Abstract

A closure for containers for making a prior opening of the closure visible has a cap-shaped inner part (20) with a face (22) and a surrounding wall (25), the wall (25) being provided with an internal thread (28), which can be engaged with the external thread (18) of the container (12). A cap-shaped outer part (50) overlaps the inner part (20) and has a face (52) as well as a surrounding wall (55), the inner part (20) being rotationally mounted with annular flanges (32) inside the wall (55) of the outer part (50). In order to be able to indicate the opened state of the container, the outer part (50) has a viewing opening (68) in at least one outer surface (51), whereas the inner part (20), on its outer surface (21) facing the viewing opening (68) of the outer part (50), carries at least two differently fashioned visible surfaces (41, 42). In addition, at least one coupling device (80) is formed between the wall (25) of the inner part (20) and the wall (55) of the outer part (50). This coupling device fixes the inner part (20) and the outer part (50) with regard to one another in a defined angular position after the container (12) has been opened for the first time. The angular position of the inner part (20) relative to the outer part (50) can be visually and/or tactilely perceived on the visible surfaces (41, 42) in the viewing opening (68).

Description

Closure for visualizing a previous opening

The invention relates to a closure for containers for visualizing a previous opening.

Containers for food, drinks, medicines and the like but also for cleaning and household agents are regularly closed with a screw cap. This is usually cap-shaped and provided on a circumferential wall with a single or multi-start internal thread, which engages in a corresponding external thread on the container.

To determine whether a container has already been opened, the lid is provided with a seal, which is injured when first opened. This is, for example, a ring which is formed on thin webs of material at the bottom of the lid wall. The ring also has a radially inwardly directed collar, which is supported in the closed position of the lid from below to a formed on the container, radially outwardly directed projection. Closing the container for the first time after filling, the ring of the lid slides over the projection of the container. When opening, however, the ring with its collar remains hanging on the projection of the container. The material webs rupture during further rotation of the lid, so that the ring is completely separated.

The disadvantage of this is that the ring remains after unscrewing the lid on the container. If this is to be reused for refilling, for example in the context of a deposit bottle system, the ring must be removed before each cleaning of the bottle in a separate step, which is correspondingly expensive. If a container that has not yet been completely emptied is closed again with the lid, so you can hardly see visually whether the container has already been opened or not, especially if the bottles are in a box and you can see the lid only from above.

DE-A1 42 06 123 proposes to oversize some of the webs of material between the lid and the sealing ring and to provide the ring in the circumferential direction with a separate predetermined breaking point, so that it ruptures when opening the container and only partially detached from the lid.

Thus, the remaining ring on the lid - the so-called tamper ring - while always completely removed from the container. However, resealing the container is often difficult because the ring depending on the lid can easily get into the screw thread. Also, it is not uncommon that neither the ring nor the material webs rupture, with the result that you can hardly distinguish whether the container has already been opened or not correctly filled. If the tamper ring is made with cutting tools, in addition to high tool and spare parts costs, a high proportion of broke, which often leads to complaints of the bottler. Moreover, this type of backup requires additional material in the area of the container opening in order to be able to attach the revolving tamper belt at all. This, too, has a negative impact on the overall costs. The lid looks visually less appealing overall.

Other known, for example from DE-A1-196 41 868 or DE-C2-198 51 508 known solutions provide that an edge provided in the cover actuator is pivoted upon closing of the container after the first opening such that a signal element in the surface of the Cover appears or is issued. Furthermore, EP-A1-0 419 272 provides a signal element formed in the circumferential wall of the cover, which interacts with a flange-shaped opening edge formed thereon the first time the container is opened and is made visible laterally.

All these proposals are due to the relatively complex lever mechanisms altogether complicated in construction and correspondingly expensive to manufacture. In addition, the opening indicator usually appears only when the lid has been closed again after first opening, ie when you open the bottle for the first time after filling, the lid retains its original appearance, which virtually challenges manipulation. A bottle closure disclosed in DE-A1-32 24 463 dispenses with elements which are torn open, pushed in or exhibited upon opening. Rather, the cap-shaped screw cap has a sealing element, which is rotatably mounted on a journal formed on the inner end face of the lid and has coaxial with this two segment-shaped recesses (grooves). The lid has two inner drivers on the front side, which each engage axially in the recesses of the sealing element. Each of these grooves is limited in the direction of rotation of end walls, wherein before each wall on the bottom of the recess, a latching element is formed which forms a sliding ramp in the opening direction and in the other direction of rotation a stop surface. In the end face of the lid two segment-shaped recesses are further introduced, which lie over an annular region of the sealing element. There are printed information that - depending on the position of the lid and sealing element to each other - are visible through the recesses.

When the lid is closed for the first time, information can be seen in the recesses indicating to the user that the container has not yet been opened. When the closure is opened, the cover is first rotated relative to the sealing element frictionally held in the bottle neck until an information appears in the recesses indicating that the cover has already been opened. At the same time this is locked on the driver on the sealing element, so that both components can only be rotated together. So that the display can not be accidentally done, the lid is secured against the sealing element by means of wax bonding.

Both the cover and the sealing element are structurally very expensive and correspondingly expensive to manufacture, which has an unfavorable effect on the tool costs. But the assembly effort is very high, because the sealing element must be rotatably mounted on the axle journal and axially displaceable. For the application of the desired information is only a narrow annular area on the sealing element available, which can not be arbitrarily labeled depending on the material. Further problems are the frictional engagement between the sealing element and the neck of the bottle and the wax guard, which do not always ensure a reliable function. If the friction is too low, the seal may come off before a change of display takes place. If the friction is too great, the closure is difficult to open. The use of wax can hardly meet today's requirements of food safety. In addition, manipulations are easily possible. Another disadvantage is that in the recesses of the sealing element dirt and impurities can settle, which are difficult or impossible to remove. This can be particularly problematic when the container must be stored for a long time.

The aim of the invention is to overcome these and other disadvantages of the prior art and to provide a closure for the visualization of a previous opening for containers, which is constructed with simple means and inexpensive to produce. The closure should not only display information about the closed or open state, but also provide space for individual labels and designs that are always visible and easily recognizable. The aim is also a simple installation and always reliable handling. The total cost of materials should be low overall.

Main features of the invention are specified in claim 1. Embodiments are the subject of claims 2 to 76.

In a closure for containers for visualizing a previous opening, the solution according to the invention provides the combination of the following features: ^■ an inner part has a circumferential wall and at least one engagement element, which is engageable with a thread of the container;

^■ an outer part overlaps the inner part and has an end face and a circumferential wall,

^■ the inner part is rotatably mounted in the outer part, ^■ the outer part has at least one viewing port;

■ the inner part has at least one visible surface;

■ between the inner part and the outer part, at least one coupling device is formed, which holds the inner part and the outer part when first closing the container in a first angular position to each other and after the initial opening of the container in a second angular position fixed to each other inextricably, passing through the viewing aperture Based on the visible surfaces, the first and the second angular position of the inner part relative to the outer part is visually and / or tactually recognizable.

This bottle cap construction is not only simple and inexpensive. Above all, it ensures that you can quickly and conveniently open (full) bottles of already opened bottles at a distance and from different directions Can distinguish bottles. The construction is such that the closure changes its appearance after opening. He can change his color as well as signs, motifs, writings or statements. The viewing opening in the outer part of the closure is moved over an inner part and fixed permanently from a certain position. When moving in the opening direction, a hitherto invisible visible surface of the inner part is revealed. This leads to the visual change and distinctness of unopened bottles. To fill the bottle from the factory, a single closing rotation is possible.

In the inner part of the closure, a sealing element is preferably integrated. The closure consists for example of a mass-producible material such as plastic or sheet metal and is thus inexpensive to manufacture.

Another important embodiment of the invention provides that between the inner part and the container at least one device is formed, which fixes the inner part in its end position after the initial closing of the container. This ensures that the outer part and the inner part can not be accidentally rotated against each other. The inner part rather remains in its original closed position until the outer part reaches the second angular position and the opening indicator has changed reliably and completely. Only then can the container be fully opened.

The closure according to the invention, which is usually in two parts, thus combines multiple, effective properties in a design which is as simple as it is inexpensive. Further advantages are therefore as follows:

^■ The tamper-evident invention requires no annoying Tamperband more, which not only has a favorable effect on the handling of the cap, but also on the total material costs. ^■ One recognizes the original seal even at a distance, especially from above. This is not only in private but above all in the commercial storage of drinks, liquids and the like. advantageous.

^■ The surface, which is initially hidden and becomes visible when the container is opened, has a universal advertising benefit that goes far beyond the mere opening indication. ■ The optical improvements compared to conventional constructions create a multiplicity of buying incentives, in particular as a novel unique feature in the marketing environment of the beverage industry.

■ The novel functions of the closure lid with visible surfaces and / or storage compartments awakens consumer attention. The consumer is also playfully involved. He can benefit several times (for example, through a clear and reliable information about the opening state, improved hygiene, better appearance up to a raffle).

The closure construction ^{according to} the invention makes it possible to specifically address consumer groups or groups, for example adults, adolescents and children. The integration of color or graphic codes can contribute to better visibility, which is beneficial, for example, for the elderly or people with poor eyesight.

^■ The closure is extremely effective on PET mineral water or brown PET beer bottles. The "bottle pulling" in the box is no longer necessary to detect whether a bottle is still full or already empty.

^■ The seal ^{according to} the invention not only provides a clear and reliable recognizable freshness seal, but also a higher food safety and a lower risk of manipulation. The seal ^{according to} the invention can also be used, for example, as a safety seal for motor oil sale containers or other lubricants and operating materials.

^■ Empty bottles are easier to recycle (recycling) because no colored lid residue is left on the bottle neck. ^■ The inner part is secured by a releasable fixing device when it is first opened relative to the outer element. The latter is designed so that the inner part relative to the container is released only when the appearance of the closure has changed visibly.

^■ The closure can be used on standardized PET bottles / containers and on glass bottles - or individually as a system solution in conjunction with

Material-saving, cost reduced PET bottle.

■ The closure is monochrome cost printable for two possible material colors - or even without printing costs produced, for example, with embossed icons that explain the closure in its function logically. ■ The inner part performs several functions. It is, for example, screw cap, information carrier, sealing element and the like. ■ The inner part can save further material costs as a skeleton construction. Or one uses a divided thread run, possibly in conjunction with a shortened bottleneck.

The closure according to the invention thus offers a visual-technical tamper-evident. He also creates space for image-promoting and customer-binding measures of the bottler, in which the consumer can be playfully involved - at the same address his ratio in conjunction with the advantages mentioned.

In the form of a system solution, it is possible to achieve the approximately same cost of materials as a conventional, e.g. 28 mm screw tamper closure in conjunction with a regular bottle including bottle neck for tamper protection required.

This is u.a. achieved in that the inner part of the two-part construction can be constructed like a skeleton, i. It consists of a supported thread run, which is interrupted by breakthroughs. A separate sealing insert will be eliminated because the inner part already acts as a seal, ideally it is made of a softer material than the outer part, e.g. made of PET.

The traditional Tamperband falls away, this material is eliminated. If the bottleneck is shortened accordingly - and optionally dispensed with a further bulge, fall again material costs, without the functionality and reliability of the cap is impaired. The bottleneck can also be interrupted cost-saving in Gewindelauf. Furthermore, the inner and the outer part are each so thin-walled functional that both as a whole in turn reach approximately the strength of a conventional single lid. The head of the outer element is usually half, in other variants even further recessed. The more of these properties are used, the more effective the production.

The generally designated 10 in Fig. 1 closure is designed as a screw cap and screwed onto a container 12. This is, for example, a beverage bottle with a (unspecified) body which tapers conically towards the upper end and forms a neck 14 over an annular collar 13. This limits with its upper edge 15 an opening 16 for filling and emptying the bottle 12. Between the collar 13 and the edge 15, an external thread 18 is formed on the outer circumference of the neck 14.

The closure 10 is constructed in two parts. It has a generally cap-shaped inner part 20 with an integrated sealing element 90 and also a cap-shaped outer part 50, which completely overlaps the inner part 20. Both closure parts 20, 50 are arranged substantially coaxially and rotatably supported at least in phases relative to each other, but otherwise by means of radially formed coupling devices 80 rotatably coupled together, so that the inner part 20 and the outer part 50 for opening and closing the bottle 12 together about the axis of rotation A can be rotated (see Figs. 2 and 3). On the inner part 20 marking elements 41, 42 are applied, preferably two differently shaped visible surfaces. These show through a viewing area 68 in the outer part 50 therethrough the angular or rotational position of the inner part 20 relative to the outer part 50, wherein, based on the Visible surfaces 41, 42 (and their design) can recognize whether the bottle 12 is still original sealed or has already been opened to remove the contents (see Fig. 4 and 5). The viewing area 68 is, for example, a semicircular viewing opening in the end face 52 of the outer part 50.

The cap-shaped inner part 20 has - as shown in FIG. 1 - a substantially flat end face 22 and a circumferential cylindrical wall 25, which is provided on its inner circumference 27 with a matching to the external thread 18 of the bottle 12 engaging element 28, namely an internal thread.

The end face 22 carries on its inner side 23, the sealing element 90, which preferably comprises an annular flange 92 which engages in the closed position of the closure 10 frictionally and sealingly in the opening 16 of the bottle neck 14. At the same time defines a limited by the wall 25 and the annular flange 92 annular portion 24 of the end face 22 sealingly on the upper edge 15 of the bottle 12, wherein in the transition from the end face 22 to the wall 25 an additional (not shown) elastic sealing lip may be formed , The (unspecified lower edge) of the annular flange 92 is slightly bevelled or rounded in order to facilitate the entry of the annular flange 92 into the neck of the bottle 14.

On the outer circumference 26 of the wall 25 of the inner part 20, two annular ribs 32 are respectively formed parallel to the upper and lower edge region, which project radially beyond the cylindrical outer periphery 26 of the wall 25 and engage in a form-fitting manner in the outer part 50.

The cap-shaped outer part 50 also has a substantially flat end face 52 and a circumferential cylindrical wall 55. The latter is provided for receiving the ribs 32 of the inner part 20 at its inner periphery 57 with two annular grooves 64, each of obliquely inwardly directed leadership or Sliding surfaces 62 are limited. The lower edge 58 of the outer part 50 forms a radially inverted collar 59, which also forms a guide or sliding surface 62 for the inner part 20. The collar 59 engages under the preferably conically shaped lower edge 30 of the inner part 20, so that it is additionally secured axially.

It can be seen that the inner part 20 is axially fixed-rotatably mounted with the formed on its wall 25 annular ribs 32 in the wall 55 of the outer part 50. In this case, the perpendicular to the axis of rotation A circumferential ribs 32 and grooves 64 in Axially acting locking elements with which the inner part 20 can be latched in the outer part 50.

This reduces the entire assembly effort to a single axial join the joining process, which has a favorable effect on the production costs. Separately formed stub axles are just as necessary as special tools for connecting the components 20, 50. These are rather relatively simple, which reduces the material costs to a minimum. But the tool costs are significantly reduced due to the simple geometric structure of the closure members 20, 50.

By the obliquely or conically shaped guide and sliding surfaces 62 of the inner part 20 is automatically centered with respect to the axis of rotation A, so that both parts 20, 50 are always guided reliably and smoothly into each other. The end faces 22, 52 of the inner part 20 and of the outer part 50 also contribute to this. These lie flat-sliding on each other after assembly, thus ensuring a permanently stable sliding guide. Forces acting on the outer part 50, which arise during opening and closing of the closure 10, are always transmitted uniformly to the inner part 20. This can not tilt relative to the outer part 50, so that the closure 10 can always work properly.

The upper edge 29 of the wall 25 of the inner part 20 is preferably bevelled. It thereby forms a run-on slope for the lower edge 58 of the wall 55 of the outer part 50, so that further simplifies the assembly process. The inner part 20 slides easily into the outer part 50 and is reliably held and guided by this.

In or on the end faces 22, 52 of the inner part 20 and the outer part 50 formed beads 36, 66 or depressions provide additional centering of the components 20, 50. Moreover, the centrally located beads 36, 66 sprue points for the preferably made of plastic Components 20, 50 form, which also has a favorable effect on the visual appearance. At the same time, the production costs are further reduced.

The coupling devices 80 provided radially between the wall 25 of the inner part 20 and the wall 55 of the outer part 50 are each formed by a driver element 82, a stop element 84 and a latching element 86, which in the axial direction preferably between the ribs 32 of the inner part 20 and the grooves 64 of the outer part 50 are. In the present embodiment, two coupling devices 80 are provided, which are at an angular distance of about 180 °. As shown in FIGS. 2 and 3, the driver element 82 is formed on the inner circumference 57 of the wall 55 of the outer part 50, while the stop element 84 and the latching element 86 attach to the outer circumference 26 of the wall 25 of the inner part 20. The integral with the outer part 50 driver element 82 and the circumferentially relatively close together and preferably integral with the inner part 20 coupling elements 84, 86 are arranged or formed so that the stop element 84 for the driver element 82 in both the closing direction S and in Opening direction O each forms a stop, so that the driver element 82 can be moved in neither one nor in the other direction over the stop element 84 away. In contrast, the latching element 86 forms a sliding ramp for the driver element 82 in the opening direction O, ie the driver 82 can slide over the latching element 86 in the opening direction O. In the closing direction S, however, the locking element 86 prevents any further movement of the driver element 82. This can therefore - if it has been moved once in the opening direction O on the locking element 86 away - not be moved back again.

The mode of operation of the closure 10 according to the invention is thus as follows:

Before the first closing operation, the inner part 20 is opposite the outer part 50 in a first angular position (FIG. 2). The driver element 82 abuts the stop element 84 in the closing direction S. A first viewing surface 41 on the end face 22 of the inner part 20 is positioned so that it is visible through the sighting opening 68 introduced in the end face 52 of the outer part 50. The first visible surface 41 carries, for example, the information "closed", "new" or the like., Based on which it can be seen that the inner part 20 and the outer part 50 are still in the first angular position to each other and that the bottle 12 has not yet opened has been.

Because the driver element 82 of the outer part 50 abuts in the closing direction S on the stop element 84 of the inner part 20, the closure 10 can be placed after filling the bottle 12 on the bottle neck 14 and screwed by turning the outer part 50 in the closing direction S without the Display in the sight opening 68 changes. The outer part 50 takes the inner part 20 via the coupling device 80, until the inner part 20 is seated tightly on the bottleneck 14. The bottle 12 is now firmly closed, the outer part 50 but not yet verkuspelt with the inner part 20 inextricably. The outer part 50 can rather be rotated relative to the inner part 20 in the opening direction O, without that the inner part 20 rotates because, for example, the annular flange 92 and the annular portion 24 of the sealing element 90 frictionally rest against the neck 14 of the bottle 12 and the static friction of the sealing element 90th in the bottleneck 14 is greater than the static friction between the inner part 20 and the outer part 50.

In order to open the shutter 10, serving as a handle outer part 50 is rotated in the opening direction O. In this case, the driver elements 82 can move freely until, after approximately half a rotation, they slide over the radial latching elements 86 of the inner part 20 and come into contact with the stop elements 84. The inner part 20 continues to sit tight on the bottleneck 14. Turning the outer part 50 further in the opening direction O, the inner part 20 is also moved, because the static friction of the annular flange 92 in the bottle neck 92 is overcome. The driver elements 82 of the outer part 50 bear against the stop elements 84 of the inner part 20. The closure 10 can be fully opened to remove the contents.

The inner part 20 and the outer part 50 are now in a second angular position to each other (Fig. 3), wherein the second visible surface 42 on the end face 22 of the inner part 20 is positioned so that it through the introduced in the end face 52 of the outer part 50 viewing opening 68 is completely visible through. The second visible surface 42 carries, for example, the information "open", "open" or the like., By which it can be seen that the bottle 12 has been opened at least once.

This information is retained, even if you put the shutter 10 back on the bottle 12 and turns, because the driver elements 82 of the two coupling devices 80 are now between the stop elements 84 and the locking elements 86 and therefore can not move freely. The inner part 20 and the outer part 50 are undetachably verkuppelt each other and can only be rotated together in the closing direction S or in the opening direction O without the display in the viewing opening 68 of the outer part 50 can change again.

In the present embodiment, diametrically two coupling devices 80 are provided between the inner part 20 and the outer part 50. This allows a relative rotational movement of the outer part 50 relative to the inner part 20 before the actual opening of the bottle 12 by about 180 °. The end face 22 of the inner part 20 is generally flat. This makes it possible to form the visible surfaces 41, 42 approximately as semi-circular surfaces relatively large, each viewing surface 41, 42 preferably has the same outer contour as the viewing port 68 in the outer part 50. This has the advantage that you can always reliably detect whether the bottle 12 is still original locked or not. As long as a different colored part of the first visible surface 41 can still be seen in the viewing opening 68 in the outer part 50 and the outer part 50 relative to the inner part 20 can be moved in the closing direction S, the customer has the certainty that the bottle 12 has not yet been opened , Only when the first visible surface 41 has completely disappeared behind the end face 52 of the outer part 50 and the second visible surface 42 completely appears in the viewing aperture 68, the outer part 50 was moved to open the bottle 12 together with the driver element 82 via the locking element 86 of the inner part 20. It then has at least an opening attempt taken place, because the inner part 20 is now firmly coupled to the outer part 50. Manipulations are thus almost impossible. Also, opening the bottle 12, without the opening display 41, 42, 68 irreversibly changed, is not possible, which further affects the reliability of the closure 10.

The closure 10 according to the invention also has the advantage that the closing or opening state of the bottle 12 is readily visible at all times from a distance and from above. It is no longer necessary to check individual bottles by lifting them.

In or on the visible surfaces 41, 42, advertising messages or other marketing elements, such as e.g. Question-answer games, competitions, slogans or logos are attached, which significantly expands the capabilities of the lid 10 of the invention over conventional closures.

In the embodiment of a closure 10 according to the invention shown in FIGS. 6 to 9, the visible region 68 in the outer part 50 is designed as a circular recess almost over the entire surface of the end face 22 of the inner part 20. The end face 52 of the outer part 50 thus reduces to a relatively narrow annular portion 67, which surrounds the inner part 20 together with the wall 55.

On its inner circumference, the annular region 67 carries a pointer element 69, which in the two excellent angular positions between the inner part 20 and the outer part 50 on a respective associated marking element 41, 42 on the outer surface 21 of End face 22 of the inner part 20 shows. The marking elements 41, 42 are visible surfaces 41, 42, which are formed as circular sectors and the opening angle, for example, each 60 °. At this angular distance two or more coupling devices 80 are arranged so that. the outer part 50 is always coupled firmly on reaching the second angular position with the inner part 20 and the pointer element 69 is located on or in the second visible surface 42. The visible surface 41 thus indicates that the bottle 12 has not yet been opened while the visible surface 42 documents that the bottle has already been opened.

It can be seen in FIGS. 6 to 8 that the end face 22 of the inner part 20 is only partially printed with visible surfaces 41, 42. The remaining part of the outer surface 21 can therefore with a company logo, product information, advertising messages or the like. be provided.

As Fig. 8 further shows, the wall 25 of the inner part 20 is skeleton-like and provided with axial webs 96 and apertures 97, which significantly reduces the cost of materials. Depending on requirements, one can reduce the wall 25 to a few axial webs 96, the internal thread 28 and the annular flanges 32. But you can form the wall 25 but only in some areas as a skeleton.

A likewise material-saving and therefore cost-effective embodiment of the closure lid 10 is shown in FIGS. 10 and 11. The inner part 20 carries on the outer circumference 26 of its wall 25 an external thread 28 ', which engages as an engaging element in a correspondingly formed (not shown) internal thread in the neck portion 14 of the (also not shown) container 12.

The wall 55 of the outer part 50 is reduced in its axial height so far that the end face 22 of the inner part 20 and in the upper region of the wall 25 of the inner part 20 formed annular flange 32 is enclosed. The closure 10 is thus in the closed position with the lower edge 58 of the outer part 50 on the (not shown here) edge 15 of the container 12.

With this variant, a lot of material can be saved, especially if the inner part 20 is additionally formed skeletal. The latter is screwed to the outer part 50 in the bottle 14 provided with an internally threaded bottle and at the same time serves as a seal. The threaded portion 28 of the lid 10 is now "sunk" in the bottle 12. Outside of the bottle 12, only the relatively flat outer part 50 is visible, causing an interesting and eye-catching appearance. Depending on the angular position, the visible surfaces 41, 42, which indicate whether the bottle 12 has still been unopened or already opened, are visible through the front opening 68 introduced in the material-reduced outer part 50. In order to effect or fix the display change, coupling devices 80 (not shown) are provided between the inner part 20 and the outer part 50, the coupling elements 82, 84, 86 of which are arranged at equidistant intervals in the circumferential direction and preferably above or below the annular flange 32 the wall 25 of the inner part and the wall 55 of the outer part 50 are located.

In the embodiment of Fig. 12, the wall 25 of the inner part 20 is substantially reduced to two narrow, diametrically opposed axial webs 125. The webs 125 carry end on their inner surfaces 27 each have a pin 128 which engages in a specially designed external thread 18 on the bottle neck 14.

The greatly simplified thread form 18 shown in Fig. 13 allows a half-rotation detent or a half-turn opening of the closure lid 10 by the pins 128 of the inner part 20 after half a rotation of the outer part 50 in the closing direction S in a latching-closed position. In this position, the inner part 20 and the outer part 50 are in their first angular position to each other. The visible surface 41 on the end face 22 of the inner part 20 indicates through the sight opening 68 in the outer part 50 through that the bottle 12 has not yet been opened.

When opened by the consumer for the first time, the outer part 50 initially makes a half turn due to the coupling device 80 (not shown here) between the inner part 20 and the outer part 50, so that the hitherto invisible visible surface 42 appears in the viewing opening 68 in the outer part 50 , The inner part 20 continues with its integrated sealing element 90 sealingly on the edge 15 of the bottle 12. The locking pins 128 are still in their latching-closed position.

If the outer part 50 reaches the second angular position relative to the inner part 20, it is firmly coupled to the inner part 20 by the coupling device 80. A further half turn of the outer part 50 then leads to the complete opening of the bottle 12, because the driver elements 82 of the coupling device 80 between the stop elements 84 and the locking elements 86 are fixed inextricably. Now, the opening and closing of the bottle 12 always requires only half a turn. As can be seen in FIG. 12, the outer part 50 is also material-saving, in particular skeletal in shape, with two opposing axial wall sections 155 obscuring the axial webs 125 of the inner part 20, when the inner part 20 and the outer part 50 in the of the coupling device 80th defined first and second angular positions. Manipulations before the first opening are effectively prevented. A lower ring portion 156 ensures a stable running of the outer part 50.

A further advantage is that the appearance of the side design of the closure lid 10 remains unchanged despite the permitted relative to the first opening relative movement between the inner part 20 and the outer part 80 after opening the bottle 12, whereas the appearance of the lid surface 52 within the viewing aperture 68 clearly visible changed.

Due to the low opening effort, the embodiment of the closure lid 10 according to FIGS. 12 to 14 is particularly suitable for bottles 12 with drinks, e.g. be used during sports or driving a car.

The development of FIG. 15 provides that a storage compartment 146 for added items P, so-called premium, is provided within the closure 10 according to the invention. Both the inner part 20 and the outer part 50 are constructed axially higher for this purpose, wherein at a height H above the closed end face 22 of the preferably skeleton-shaped inner part 20 a semicircular surface element 141 is arranged, the surface slidably on the underside of the end surface 52 of Outer part 50 abuts and over eg separately formed axial webs or struts 143 is connected to the wall 25 of the inner part 20. In the circumferential direction, the storage compartment 146 is bounded by the wall 55 of the outer part 50. But you can also form the wall 25 of the inner part 20 correspondingly higher.

Are the inner part 20 and the outer part 50 - ex works - in their first angular position to each other, then the surface element 141 is completely as a closure under the viewing opening 68 in the outer part 50, ie the storage compartment 146 is closed and not accessible from the outside. The Fiächenelement 141 also indicates as a marking element that the bottle 12 has not yet been opened. A visible surface 41 applied to the surface element 141 can supplement this information, for example by inscriptions or picture elements. A formed between the inner part 20 and the outer part 50 (not shown here) securing device 170 prevents the outer part 50 can prematurely or accidentally rotate relative to the inner part 20, so that the storage compartment can be opened prematurely. The securing device 170 is, for example, a latching device which, after first closing the container 12, locks the inner part 20 and the outer part 50 in the first angular position relative to one another and can be released when the container 12 is opened for the first time by overcoming a resistance force. The latter is always smaller than the static friction between the inner part 20 and the container 12, so that the shutter 10 does not open prematurely when the outer part 50 is moved relative to the inner part 20 from the first angular position to the second angular position.

The latching device 170 has the further advantage that the closure 10 can be supplied with an open storage compartment or reservoir 146 if necessary. In this case, the on-site bottler will be able to fill the reservoir 146 himself. Subsequently, the outer part 50 is rotated in the closing direction S until it locks in the first angular position with the inner part 20. The closure 10 can now be placed on the bottle 12 and firmly closed.

Alternatively, instead of a latching device 170 between the inner part 20 and the outer part 50, a tamper connection (also not shown) can be provided which ruptures the first time the bottle 12 is opened. Man can structurally unite the securing device 170 with the coupling device 80, which would be structurally advantageous.

After the consumer opening the storage compartment 146 remains fixed due to the formed between the inner part 20 and the outer part 50 coupling device 80 is opened, so that one can clearly distinguish already opened container 12 12 of sealed containers. The opening 142 of the storage compartment 146 - which may be accessible through the wall 55 of the outer part 50 if necessary - thereby forms the second marking element which indicates in the second angular position between the inner part 20 and the outer part 50 that the bottle 12 has already been opened ,

Depending on the size of the opening 142 can in a further variant, the bottom of the storage compartment 146, ie, the end face 22 of the inner part 20 individually characterize, for example with a logo or an advertisement. This also contributes to the fact that one also from far and especially from above can recognize whether the bottle is still original sealed or has already been opened.

Premium PVCs are soft PVC toys, collection rings and similar accessories that fit in a relatively small space. Also (individually packaged) food of all kinds can be integrated in the storage compartment 146, for example as samples. Such an embodiment of the closure 10 is suitable, for example, for joint ventures or a large number of promotions.

The closure 10 according to the invention from FIG. 17 provides that on the outer circumference 26 of the wall 25 of the inner part 20, two visible surfaces 41 ', 42' are applied. The first viewing surface 41 'indicates in the first angular position between the inner part 20 and the outer part 50 that the container 12 has not yet been opened. The second visible surface 42 ', however, appears when the shutter has been opened for the first time, that is, when the inner part 20 and the outer part 50 are in the second angular position to each other and the coupling device 80, the cover parts 20, 50 undetachably coupled together. For this purpose, in the wall 55 of the outer part 50, a lateral viewing opening 68 'is introduced, which may extend over half the circumference of the outer part 50, for example.

The end face 52 of the outer part 50 is reduced to a relatively narrow annular portion 67, which encloses the inner part 20 together with the wall 55. The visible in the circular view opening 68 outer surface 21 of the end face 22 may therefore be provided with a company logo or a perpetual advertising, which always remains unchanged unchanged regardless of the opening or closing state of the bottle 12.

The inner part 20 is preferably formed skeletal in the wall area for material reduction, which can be used in the original state, the skeletonization as a viewing surface 41 ', so as to bring about the closed and printed with an information visible surface 42' a distinct discrimination contrast. The visible surface 42 'is then visible only after the opening latching by the coupling device 80. However, the visible surfaces 41 ', 42' can also be reversed, as shown in FIG. 18, so that the skeletonization appears as a marking element 42 'when the bottle 12 has been opened. As a result, for example, the "used" character of the bottle 12 is underlined. For example, in order to make raffles in the lateral viewing window 68 'more extensive and, above all, more individual, it is also possible to have a printed plastic film or a laminated paper (not shown) as a marking element 41', 42 'on the outer circumference 26 of the skeletal wall 25 of the inner part 20 apply. The film is always located between inner part 20 and outer part 50. In this case, further material savings is possible because the platform behind the action field 68 'is no longer required. The film may also be perforated or peelable, for example, to submit prize coupons to the manufacturer. A food-safe scratch principle is also possible.

A further embodiment of the invention has in the edge region of the lateral viewing opening 68 'a e.g. vertically mounted or formed tubular depot 46, in which a rolled-up surface element 44 is inserted in the form of a film or a banner. The foil 44 or the banner is factory-connected to the inner part 20, e.g. wedged, jammed or glued. When opening the closure 10 for the first time, the film 44 is rolled out of the depot 46 between the wall 25 of the inner part 20 and the wall 55 of the outer part 50, so that a separate visible surface 43 applied thereto is visible as a marking element within the viewing opening 68 '. The film 44 has reached its entire propagation in the action window area 68 'of the outer part 50 until the permanent fixing state of the inner part 20 and the outer part 50 in the second angular position. It then remains in this state even when repeated closing and opening the bottle 12th

In the embodiment shown in FIG. 20, a multiplicity of lateral viewing openings 68 'are made in the side wall 55 of the outer part 50. The marking elements 41 ', 42' printed on the outer circumference 26 of the side wall 25 of the inner part are - as well as the coupling devices (not shown here) 80 arranged in correspondingly narrow angular distances from one another.

Therefore, instead of half a turn, this version of the closure 10 according to the invention requires only a few millimeters of movement until the coupling devices 80 have coupled the inner part 20 to the outer part 50 in the second angular position in a non-detachable manner.

As FIG. 20 further shows, the inner part 20 has been reduced to the wall region 25, which has an extremely favorable effect on the material consumption. The inner part 20 thus forms a ring which is inserted in the wall 55 of the outer part 50 and rotatably locked.

Radially formed on the inner part 20 engaging elements 72 of a securing device 70 ensure that the inner part 20 remains fixed after the initial closing of the container 12 and during the first rotational movement of the outer part 50 in the opening direction O in its first angular position, which will be shown in more detail below.

The embodiment of a closure blanket 12 according to the invention shown in FIGS. 21 to 23 uses as marking elements no changing visible surfaces 41, 42 or 41 ', 42' or viewing and opening surfaces 141, 142 which are in view openings 68, 68 'in FIG

Outer part 50 appear, but the combination of intact areas

241, 241 'and embossing elements 244, which leave clear marks within defined viewing areas 268, 268' after the first opening of the container 12 in the previously intact surface areas 241, 241 '. On the basis of these deformed and / or color-changed surface areas 242, 242 'is always reliably recognizable whether the container 12 has already been opened or not.

The inner part 20 is rotatably mounted in the outer part 50. He wears on its end face 22 an embossing element 244, which is formed as a vertical pointed or cutting rib and arranged edge. In variant a) of FIG. 21, the embossing element 244 forms a single point whose flanks fall off on both sides in the circumferential direction. In variant b) of Fig. 21, the rib 244 is made longer, e.g. over an angular range of 120 ° or 160 °. Variant c) of FIG. 21 uses, instead of a continuous stamping element 244, a plurality of tips arranged one behind the other, which - as well as the longer rib - can vary in height.

Important in this embodiment is that the inner part 20 and the outer part 50 are axially arranged and guided during the initial closing and before the first opening of the bottle 12 so that the embossing elements 244 can not touch the outer part 50. The latter has - as FIG. 22 shows - in the region of the end face 52 an annular surface area 241, which has a reduced material thickness relative to the wall 55 and the remaining area of the end face 52 of the outer part 50. The intact area 241 also forms the second visible surface 242 and the viewing area 268, namely, when the embossing element 244 as a marking element plastically deforms the previously intact surface 241 by mechanical action. The mode of operation of the closure 10 according to the invention is thus as follows:

Turning the shutter 10 for the first time, the inner part 20 is taken from the outer part 50 via the (not shown here) coupling device 80 and screwed onto the bottle neck 14. A mechanical deformation of the surface area 241 does not take place. The inner part 20 and the outer part 50 are in the first angular position to each other. The consumer recognizes at the intact surface areas 241 that the bottle 12 has not yet been opened.

If the closure 10 is opened via the outer part 50, the inner part 20 initially remains in its closed position until after about half a turn the coupling device 80 has coupled the two cover parts 20, 50 inseparably together. Already shortly before reaching this second angular position between the inner part 20 and the outer part 50, the embossing elements 244 of the inner part 20 engage within the viewing areas 268 in the hitherto still intact surface areas 241. These are plastically deformed due to the reduced material thickness of the ribs 244 shown in Fig. 21, so that it is irretrievably recognizable from the surface areas 242 now marked, that the bottle 12 has already been opened.

The embossing elements 244 of the inner part 20 need not penetrate the surface areas 241 in order to effect the display change. It is sufficient to deform the plastic in the defined viewing area 268. This results in a typical white fracture color, the so-called white fracture. This is particularly well recognizable from a distance, especially when using colored plastics.

As indicated by arrows 245 in FIG. 22, in addition to the resulting white fracture, the region of the end face 52 enclosed by the viewing region 268 of the outer part 50 can be raised, whereby the optical change is further enhanced. For this purpose, the embossing elements 244 and / or the inner part 20 are provided with corresponding adjusting elements (not shown), e.g. a ramp.

The embodiment of FIG. 23 uses a single pointed rib as the embossing element 244, which is arranged on the end face 22 of the inner part 20 (see FIG. 21a). If it comes to the first opening, the rib 244 penetrates upon reaching the second angular position between the inner part 20 and outer part 50 in a circular field of view 268, the hitherto unscathed marking element 241 now by white fracture as the second Marking element 242 is marked. The remaining area of the end face 52 of the outer part 50 can be printed with advertising messages or other marketing elements.

So that the inner part 20 always remains securely in its closed position before the first opening, a securing device 70 is formed between the inner part 20 and the container 12. This is, for example, a latching device 71, which has at least one locking lug 72 formed on the inner part 20. The latter engages in the closed position of the inner part 20 positively in a (not shown) latching recess 74 in the bottle neck 14 of the container 12 a. Only after the permanent coupling of inner part 20 and outer part 50 by the coupling device 80, the locking lugs 72 release from the locking recesses. The container 12 can be opened.

In order to bring the embossing elements 244 into contact with the intact surface areas 241, it is possible to insert, for example, between the inner part 20 and the outer part 50

(Provide unspecified) Provide adjusting thread, by which the outer part 50 is initially moved axially relative to the inner part 20 when first opened, before the entire closure 10 unscrews from the bottleneck 14. You can do that

Embossing elements 244 but also lead over (not shown) ramps, so that the unopened before opening surface areas 241 are marked upon reaching the second angular position between the inner part 20 and outer part 50. This then signals the opening made and is no longer reversible.

The embossing principle works with all colorful lid colors and plastics suitable for fracture discoloration. Depending on the application needs, there is the possibility with the

Embossing elements 244 within the viewing areas 268 letters or symbols in the

Emboss areas 241. Since this visualization of an opening is not only a visual but also a haptic marking, this originality assurance is also suitable for the blind.

In the variant of FIG. 24a, the visualization of the first opening takes place in the radial direction

Direction.

The inner part 20 is designed to reduce the material ring, ie reduced to the wall 25. In this example, webs 246 are formed at four equally spaced locations, which are mounted parallel to the longitudinal axis A pivotally. Every footbridge 246 carries at its free end a marking element 244 ', namely an embossing element which is provided in the radial direction with a tip.

The outer part 50 is provided in the region of its wall 55 with an annular viewing area 268 ', which has a reduced material thickness compared to the other wall areas. The viewing area 268 'thus forms the first visible surface 241', which signals in intact condition that the container 12 has not yet been opened (see Fig. 24b).

If the container 12 is opened for the first time, the outer part 50 moves by about 90 ° until it is non-detachably coupled in the second angular position with the inner part 20. Already shortly before reaching the dome position, the webs 246 are provided with the embossing elements 244 'radially outward, so that the previously intact surface areas 241' are at least partially plastically deformed. The resulting white fracture surfaces 242 'irretrievably indicate that the container 12 has been opened at least once (see Fig. 24c).

To supplement or alternative to the previous embodiments to avoid premature co-rotation of the inner part 20 with the outer part 50 to be actuated, in particular to ensure that the outer part 50 irreversibly entrains the inner part 20 when the driver element 82 of the coupling device 80 on reaching the second Angle position between inner part 20 and outer part 50, the locking element 86 has completely overcome, between the inner part 20 and the container 12, a securing device 70 is provided.

This is formed, for example, by a rod-shaped or bar-shaped engaging element 72 formed on the lower edge 30 of the inner part 20, which after the first closing of the container 12, i. when the inner part 20 and the outer part 50 are in the first angular position to each other, engages in a corresponding receptacle 74 in the collar 13 below the bottle neck 14.

The rod-shaped or bar-shaped engagement element 72 is connected at the end to the wall 25 of the inner part 20 via a joint 34 or a film hinge. The other end of the rod 72 is also fixed to the bottom edge 30 of the inner part 20 via a material web 35, which is relatively thin with respect to the film hinge 34, so that the engagement element 72 lies approximately parallel to the lower edge 30. The downward side surface of the rod 72 is provided with serrations or teeth 38. Such are also in the recording 74 formed in the ring 13. The existing teeth or teeth 79 are directed upward. They preferably have the same dimensions and proportions as the serrations or teeth 38 of the rod 72.

If the container 12 is closed for the first time, the teeth 38 of the rod 72, when they reach the closed position, engage positively in the teeth 79 of the receptacle 74. The inner part 20 is thus non-positively connected to the container 12. If the closure 10 is opened via the outer part 50, it can first be rotated independently of the inner part 20. The latter is reliably retained by the web 74 located in the receptacle 74 until the outer part 50 reaches the second angular position and is coupled firmly to the inner part 20 by the coupling device 80. If the outer part 50 is then further rotated in the opening direction O, the relatively thin material web 35 tears. The web 72 separates from the receptacle 74. The inner part 20 can be rotated in the opening direction O.

The force required to trigger the web 72 from the receptacle 74 is greater than the force required to guide the driver element 82 of the coupling device 80 via the latching element 86. Only when the inner part 20 and the outer part 50 are permanently coupled together and the Verschluss.10 indicates optically or tactile that an opening attempt has taken place, the inner part 20 can be detached from the container 12. The torn-off web 72 illustrates, in addition to the changed appearance of the visible surfaces 41, 41 ', 42, 42', 141, 142, that the container has been opened at least once.

In order to take into account tolerances at the closing fixed point from filling, the receptacle 74 can be arbitrarily longer than the web 72, which is preferably integral with the inner part 20. The securing device 70 can be distributed over the circumference, be formed at several points, for example at a distance of 90 ° or 180 °.

29 to 30 show a simplified embodiment of a securing device 70 with two webs 72, which are connected one behind the other at an angle obliquely to the axial direction A fixed to the lower edge 30 of the inner part 20, preferably in one piece with this. The recess 74 in the edge 13 of the container 12 is - as well as the webs 72 - without teeth 38, 79 and executed twice.

When first closing slide the (double) webs 72 over the edge 13 of the container 12 until they engage with their free ends in the receptacles 74. Opens the consumer the Closure 10, tear the web 72 of the inner part 20 from visible and thus clarifies the broken additional seal to the already changed appearance of the lid 10. The position of the webs 72 and the receptacles 74, which together form a locking device, depends on the closed position of the inner part 20 on the bottle neck 14 so that the webs 72 always reliably reach the receptacles 74 during the first closure.

Another possible embodiment of a securing device 70 between the inner part 20 and the container 12 is shown in FIGS. 31 and 32.

The inner part 20 has in its wall 25 a separately formed wall part 25 ', which is connected in a (unspecified) window via a relatively small material web 39 with the main part of the wall 25. The wall portion 25 'forms an engagement element 72, which in the closed position of the closure lid 10 with a (not shown here) receptacle 74 in the bottle neck 14 of the container 12 can be brought into engagement. The receptacle 74 is formed, for example, from the end (not shown) of the male thread 18 on the container neck 14 or from any other defined recess on the container 12, e.g. the already mostly existing (but not visible here) Vent slots 19 in the bottle thread 18th

On its outer circumference 26, the wall part 25 'carries at the edge two guide lugs 47, 48 which are aligned parallel to the longitudinal axis A and can be brought into operative connection with actuators (not shown) in the outer part 50. On the inner periphery of the wall portion 25 'is - as indicated in Fig. 31 by dashed lines - a portion of the internal thread 28 is formed.

When first closing the lid 10 ex works, the wall portion 25 'completes the threaded portion 28 of the inner portion 20, as shown in FIG. As soon as the inner part 20 has reached its sealing end position on the container 12, a first actuator of the outer part 50 comes into contact with the right-hand guide nose 48 of the wall part 25 'in that last moment of the closure path (see arrow in FIG. 31). The wall part 25 'is pressed as an engagement element 72 in the receptacle 74 of the securing device 70. The inner part 20 is fixed relative to the container 12.

When first opened by the consumer, the outer part 50 engages after reaching the second angular position with a second actuator on the left guide lug 47 of the wall portion 25 '. As a result, the engagement element 72 is ejected from the receptacle 74. pressed or lifted. The wall portion 25 'returns to its original state. The inner part 20 can be moved freely relative to the bottleneck 14.

In order to ensure the trouble-free production of the inner part 20, the wall part 25 'can be sprayed on the outside and then joined inwards.

The securing device 70 in the embodiment of FIG. 33 is a locking device 71 formed between the inner part 20 and the external thread 18 of the bottle neck 14, which prevents the inner part 20 from prematurely rotating relative to the container 12 when the bottle 12 is opened. The external thread 18 is usually provided with bottles for carbonated drinks with axial gaps 19, the so-called vent slots, which are distributed at intervals over the circumference of the neck 14. In the embodiment described below, these vent slots 19 are used as latching recesses 74.

A further latching device 76 is located between the inner part 20 and the outer part 50. This prevents further safety device 170 unintentional rotation of the outer part 50 relative to the inner part 20 out of the first angular position, for example, when handling the bottle 12. The display of the visible surface 41st In the viewing aperture 68, therefore, it is only then changed when the bottle 12 or the closure 10 is actually to be opened, that is, when the locking device 76 or the safety device 170 has been deliberately overcome.

Construction and operation of the securing devices 70, 170 are shown in FIGS. 33a to 33g.

Fig. 33a shows the closure 10 ex factory. The inner part 20 has as a latching element on the circumferential side one or more cantilever spring-mounted clamping webs 72, which are each formed in a recess 37 in the wall 25 and project beyond the inner circumference 27 also radially inwardly. Each clamping ridge 72 is positioned and dimensioned so that when screwing the inner part 20 on the bottleneck 14 after filling from the external thread 18 of the bottle 12 is pressed against a restoring force radially outward (see Fig. 33b) until the shutter 10 its Has reached closing position. In this, the clamping bar 72 is - as Fig. 33c shows - on a vent slot 19 in the external thread 18. He springs radially inward and lies down with a stop edge 73 formed at the end behind a lying at the same level web of External thread 18. He thus engages in the locking recess 74 formed by the vent slot 19. The position of the clamping webs 72 within the inner part 20 is matched to the respective closed position of the closure 10 relative to the external thread 18 of the bottle 12, so that the latching device 71 always reliably engages.

Upon reaching the end position of the closure 10, the outer part 50 is rotated relative to the inner part 20 still a piece in the closing direction S, whereby a provided on the inner circumference 57 of the wall 55 of the outer part 50 resilient latching lug 77 engages in a corresponding latching recess 177 on the outer circumference of the clamping bar 72 (see Fig. 33d). The latching lug 77 and the latching recess 177 thereby form the latching device 76 of the securing device 170. The bottle 12 is now sealed. Opening or manipulating the closure 10 or the bottle 12 is not possible without conscious overcoming the securing devices 70, 170.

If the closure 10 is opened via the outer part 50, first the locking device 76 or the securing device 170 must be overcome, i. the locking lug 77 of the outer part 50 is released by force from the locking recess 177 in the clamping web 72 (Fig. 33e). The latter is further supported with its stop edge 73 in the latching recess 19, 74 on the external thread 18, so that the inner part 20 can not rotate. Only when the outer part 50 has performed its intended for the display change in the viewing aperture 68, 68 'half rotation and has reached the second angular position relative to the inner part 20, the clamping web 72 is released from the detent recess 74 and the gap 19 of the external thread 18. For this purpose-as shown in FIG. 33f-a driver 78, for example a hook 78 or a tongue, is provided on the inner circumference 57 of the wall 55 of the outer part 50. This engages behind the clamping element 72 upon reaching the second angular position and pulls it out with continuous rotation of the outer part 50 in the opening direction O radially out of the gap 19 of the external thread 18. The securing device 70 has been overcome. The cap 10 is released as a whole for opening (see Fig. 33g).

The coupling device 80 (not shown) couples the inner part 20 - as described above - to the outer part 50, so that the bottle 12 can be fully opened. The visible surface 42, 42 'appears irreversibly in the viewing aperture 68, 68' of the outer member 50 and indicates that the bottle 12 has already been opened.

The definable by the design of the locking elements force to overcome the securing device 170, 76 between the inner part 20 and the outer part 50 is It is always smaller than the equally definable force required to overcome the static friction between the sealing element 90 and the bottle neck 14 and / or overcoming the securing device 70 between the inner part 20 and the bottle 12. However, it is dimensioned so that the outer part 50, for example when gripping the bottle 12 on the closure 10 can not prematurely or accidentally turn.

The force required to overcome the securing device 70 and the locking device 71 between the inner part 20 and the bottle 12 is always smaller than the force required for irreversible coupling of the inner part 20 to the outer part 50 with the coupling device 80, so that when opening the lid 10 the second angular position can always reach complete and reliable.

The closure of FIGS. 34 to 37 dispenses with an additional securing device 170 between inner part 20 and outer part 50. Also, the clamping webs or engaging elements 72 do not automatically enter the receptacles or latching recesses 19, 74 when closing the lid 10 actuated in the outer part 50 integrated actuators 56 and pressed by these after overcoming a definable resistance force in the vent slots 19, 74. The reliability of operation of the closure lid 10 is thereby further increased.

The structure and operation of the securing device 70 is shown in FIGS. 34 to 37.

The inner part 20 and the outer part 50 are coupled to one another via the coupling device 80 (not shown here) such that the inner part 20 can be screwed onto the container 12 via the outer part 50. The in the wall 25 of the inner part

20 formed clamping webs 72 protrude - as Fig. 34 shows - not on the inner circumference

27 of the wall 25 also. Rather, they lie in recesses 53, which are on the inner circumference

57 of the wall 55 of the outer part 50 are formed. Inwardly, each clamping web 72 is at its free end by a on or in the inner wall 25 of the inner part

20 trained, resilient retaining lug 33 supported.

When the closure 10 reaches its closed position, the inner part stops such that the clamping webs 72 lie radially over the vent slots 19. However, the outer part 50 can also turn a little further here, so that the lying in the recesses 53 clamping webs 72 of the actuators 56 of the outer part 50 - overcoming the force applied by the retaining tabs 33 resistance - are pressed radially inward (see Fig. 35). In this case, the clamping webs 72 enter the vent slots 19, wherein the end formed stop edges 73 are behind the (unspecified) webs of the external thread 18. The Vent-slots 19 are as locking recesses 74 components of the securing device 70. The retaining lugs 33 fix the clamping webs 72 now in the vent slots 19, 74, wherein both the retaining lugs 33 and the clamping webs 72 of the outer part 50, in particular of the inner circumference 57 additionally secured. The bottle 12 is sealed. Opening or manipulating the closure 10 is not possible without deliberately overcoming the securing device 70.

If you open the shutter 10 via the outer part 50, it is rotated from the first angular position to the second angular position. The inner part 20 remains fixed by the securing device 70 initially in its position until the coupling device 80, the inner part 20 and the outer part 50 has permanently coupled together and the displays 41, 41 ', 141, 241, 241', 42, 42 ', 142nd , 242, 242 'in the viewing areas 68, 68', 268, 268 'the closure 10 have been optically and / or haptically changed.

Upon reaching the second angular position - after about half a turn - are the recesses 53 in the wall 55 of the outer part 50 and the Vent slots 19 in the thread 18 of the bottle neck 14 again radially behind the other, so that the retaining lugs 33 can release the clamping webs 72 ( see Fig. 36).

Turning now the outer part 50 and the inner part 20 coupled thereto in the opening direction O on, the clamping webs 72 are released by the torque generated by the consumer - against the resistance of the clamping lugs 33 - from the recesses 19, 74 and into the recesses 53 of the outer part pressed in (Fig. 37). The clamping lugs 33 return to their original state. The lid 10 is henceforth usable as any conventional closure without any restrictions.

Since both elements 20, 50 are factory-fitted together so that they also overcome a barb principle, and the latching technology is in the hidden state, manipulation is considerably more difficult. Optionally, also tear functions can be integrated, which make a repeated process of detent impossible.

Between the inner part 20 and the outer part 50, a (not shown) re-hook detent can be additionally provided, which by means of relatively small detent steps or by means of decreasing latching steps indicates that the irreversible fixation of the cover parts 20, 50 is imminent.

The modular latching principle of the aforementioned embodiments (Figures 33 to 37) is applicable in all containers 12 with vent slots 19, which are necessary for venting in carbonating drinks, for example in PET bottles for mineral water, sodas or beer. Since the engagement elements 72 only take up little space within the slots 19, the original venting provided is not impaired. However, it is also possible to use, instead of the integrated slots 19, separate receptacles 74, which are introduced in the container thread area 18.

The closure 10 shown in Figs. 38 to 40 is provided with a securing device 70, the engagement elements 72 engage in receptacles 74 on the inner wall of the container neck 14 to hold the inner part 20, while the outer part 50 from the first angular position to the second angular position is moved.

The receptacles 74 are latching depressions, which are arranged near the container rim 15 (see FIG. 40), while the engagement elements 72 form identical latching lugs which are formed either on the annular flange 92 of the sealing element 90 or on separately formed axial webs 93 (see FIG. 39) ). The arrangement of the latching elements 72, 74, which together form a latching device 71, is selected so that the latching lugs 72 engage positively in reaching the closed position of the inner part 20 in the locking recesses 74.

The force for overcoming the latching device 71 is greater than the force necessary to connect the outer part 50 in the second angular position via the coupling device 80 with the inner part 20. Turning now the outer part 50 as a handle further in the opening direction O, however, the applied torque is always large enough to overcome the locking device 71. The engagement elements 72 slide out of the latching depressions 74. The entire closure 10 can be opened.

A further variant of this embodiment provides that the latching lugs 74 and / or the axial webs 93 on initial opening of the lid 10 tear or tear. The axial webs 93 are provided for this purpose with (not shown) predetermined breaking points, which is irreversibly fixed after exceeding the second angular position, so if the coupling device 80 is permanently fixed and the shutter 10 its outer appearance in the viewing ports 68, 68 ', 268, 268' has, break up or tear down. The locking device 71 can then no longer engage after the first opening of the container 12. The lid 10 can be like a conventional lid on the container 12 and unscrew it.

The closure 10 according to the invention, as shown in FIGS. 41 to 44, uses as latching element 72 a pivotable and bendable triangle 102, which is articulated in or on the wall 25 of the inner part 20. To simplify the manufacturing process, the triangle 102 is initially outside the wall 25 (Figure 41). It is pivoted radially inward before or during assembly of the inner part 20 in the outer part 50, so that it protrudes with its tip 103 beyond the inner circumference 27 of the inner part 20 also radially inwardly (Fig. 42). Axial is the triangle 102 between the (not visible here) threads of the internal thread 28 of the inner part 20th

When the closure 10 is first closed after filling, the triangle 102 with its tip 103 follows the course of the external thread 18 on the container 12. As soon as the closure 10 has reached its closed position, the triangle 102 snaps into one of the gaps 19 (not shown) Slots) of the external thread 18 of the bottle 12.

Now opens a consumer, the closure 10 for the first time, he pushes the left turn of the outer part 50, the triangle 102 in the opening direction O. This lies in the gap

19 behind the stop edge 73 of the same level (not shown)

Web of the external thread 18 (see Fig. 42). The inner part 20 is opposite to the

Outer part 50 is locked and remains in this position until the coupling device 80 engages.

Now, by further rotation of the outer part 50, the detent function of the triangle 102 can be canceled, resulting in the entire opening of the closure 10 (see

Fig. 43).

So that the triangle 102 can not engage again in the vent slots when the closure cap 10 is re-closed, it is completely opened, as indicated in FIG. 44, so that the triangle 102 rests flat against the inner wall 27 of the inner part 20.

This embodiment thus represents a further latching function. The small, foldable triangle 102 is integrated in the threaded portion of the inner part 20. It is connected to the wall 22 by a flexible tab 104. Prerequisite for the function is a bottle thread 18 with recesses 19 (Vent slots). In a further embodiment of the invention shown in Fig. 45, additional clamping elements 94 are formed on the inner side 23 of the end face 22 of the inner part 20, which act on the annular flange 92 of the sealing element 90 with an additional radially outward force. As a result, the static friction of the annular flange 92 in the bottle neck 14 is increased when the closure is in its closed position. The clamping elements 94 may be arranged distributed in equidistant intervals over the circumference or designed as a continuously rotating element.

It is important that the friction generated by the clamping elements 94 between the annular flange 92 and the bottle neck 14 is always greater than the force that is necessary in order to engage with the driver element 82 of the outer part 50, the locking element 86 of

Clutch device 80 on the inner part 20 to overcome. If the driver element 82 abuts against the stop element 84 of the coupling device 80, the force necessary to overcome the static friction between the annular flange 92 and the bottle neck 14 can be applied without difficulty via the outer part 50. The closure 10 can be completely unscrewed.

In a further embodiment of the invention - as schematically indicated in FIGS. 46 and 47 - the engagement element 72 of the securing device 70 is formed by the lower end of the external thread 18 on the container neck 14. On the inner circumference 27 of the wall 25 of the (not shown here) inner part 20, a corresponding receptacle 74 is formed, which receives the end 74 of the external thread 18 upon reaching the closed position of the inner part 20. For this purpose, a slot 114 is formed in the receptacle 74, which forms a positive fit behind the threaded end 72. This position is preferably reached after half a turn of the lid 10 in the closing direction S.

If the outer part 50 when first opening the bottle 12, the second angular position reached, the securing device 70 is overcome by the receptacle 74 slides over the external thread 18.

In order to prevent premature rotation of the outer part 50 relative to the inner part 20, a second securing device 170 (not shown) can also be provided here. This provides, for example, a plastic tape or a chain with predetermined breaking point (s), which is formed radially between the inner part 20 and the outer part 50 and connects both parts 20, 50 from the factory. The securing device 170 would not break at the first closing rotation after filling the bottle 12, but only when the shutter 10 is opened for the first time. In yet another variant, it is possible to provide on the outer circumference 26 of the inner part 20 further detent recesses (not shown) which, when the closure 10 is opened, are passed by a detent nose (not shown) on the inner circumference 57 of the outer part 50, but without force or force therein to intervene positively. In this way, when opening the bottle 12, not only the visual display in the shutter 10 is changed. The first opening of the bottle 12 is also displayed acoustically.

The variant of Figs. 49 and 50 shows an embodiment of a securing device 170 between the inner part 20 and the outer part 50. The latter carries at its lower lid edge 58 two diametrically opposed locking webs 172, which on reaching the first angular position between the inner part 20 and outer part 50 in corresponding locking recesses 174 engage over the lower edge 30 of the inner part 20.

The locking elements 172, 174 prevent the outer part 50 from accidentally rotating relative to the inner part 20, for example, when handling the bottles 12. Only when consciously has a force been used to overcome the securing device 170, the shutter 10 can be displayed in the field of view 68, 68 ', 268, 268' change.

However, one can use the locking webs 172 in combination with the locking recesses 174 as a coupling device 80. In this case, the locking webs 172 ex factory directly adjacent to the locking recesses 174 and can be moved after the first time closing the bottle 12 in the opening direction O. Only when the inner part 20 and the outer part 50 have reached the second angular position, the latching webs 174 engage in the locking recesses 174 such that they are no longer releasable.

This type of detent is therefore used to fix the now changed appearance of the closure 10. To prevent manipulation, one can mask the locking elements 172 by (not shown) projections or by a sheath on the outer part 50.

The technique shown in FIGS. 51 to 53 replaces the laterally mounted locking webs of the coupling device 80 for fixing the external appearance of the closure lid 10 in the form of a detent plate 122 following the mold in the head part 22 of the inner part 20

Plate 122 itself requires no additional material, it is outward embossed. Further material costs require only two opposing ramps 123, through which the outer part 50 can reach the height of the detent plate 122.

At the same time, a side guide (unspecified) attached to the inner member 20 provides a height level difference, as shown in Fig. 53. Thus, if the outer member 50 is still higher in the factory, it will move during or after reaching its target distance, i. After reaching the second angular position, now put over the inner part 20 in such a way that it forms a flat surface on the head part. The plate 122 on which the

Visible surface 42 is applied, is now form-fitting within the viewing aperture 68. This provides additional stability of the fixing state, since the detent plate 122 of the inner part

20 is now closed from all sides.

In order to provide the rotation with a barb effect, a toothed detent can be integrated, see FIG. 52. The first detent step takes place with the first consumer movement of the outer part 50. For this toothing, a slightly increased material expenditure would be required. The toothing is such that it does not affect the sealing function of the inner part 20 in any way. The locking teeth in the inner part 20 are not shown here.

In order to fix the inner part 20 at the consumer first rotation, all the above-mentioned locking functions can be integrated here again.

Other important advantages of the invention are:

^■ The height of the closure 10 can be reduced compared to conventional constructions.

^■ The bottleneck 14 of the bottle 12 can be shortened because the previously provided circlip is eliminated.

^■ The closure 10 itself comes with a much smaller amount of material.

^■ The viewing opening 68, 68 'can be made considerably larger.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways. So you can, for example, the sealing element 90 and the inner part 20 also form separately, which is always advantageous if both parts 20, 90 are to be made of different materials. The sealing element 90 is simply clipped into the inner part 20 or locked in this case. Another alternative provides that. in the inner part 20 a (not shown) ring is inserted, which is preferably rotatably mounted on the outer circumference 26 of the wall 25. On the ring, the outer part 50 is attached. During the first opening of the bottle 12, the inner part 20 now remains in its position initially, whereas the outer part 50 can be rotated with the ring until the locking position defined by the coupling device 80 is reached, for example after about half a turn. The closure 10 is thereby in three parts. The previously described Zack-latching function is here also optionally used by the previously described "Barb principle".

Yet another embodiment of the invention provides that the display change is generated within the viewing ports 68, 68 'by a chemical reaction or reaction, triggered by mechanical forces. For this one can e.g. below or within a transparent seal that the consumer can see, provides a solid, food grade substance that has a source color ex works. Once this substance comes into contact with the liquid contents, it is "armed", but does not change its color in a vacuum. As soon as the substance reacts with oxygen, it immediately changes its color and the seal is visibly recognizable as "unsealed" from the outside. However, it is also possible by the rotation of the outer part 50 relative to the inner part 20 bring together several substances within a viewing aperture 68, 68 ', so that a color change comes about (in this case, the substances have no contact with the content). Or the mechanical rotation triggers a reaction of only a single substance, which leads to the color change.

In another (not shown) option, the locking recesses 177 can be repeatedly and so designed that the latching lug 77 on the outer part 50 can always be moved only in one direction, namely in the opening direction O. The once started opening rotation can not be undone.

This latching principle is associated with corresponding counter-elements in the interior of the outer part 50. The Fixierstrecke to the final changing appearance takes place in small, non-returnable steps. Thus, the outer part 50 each engage conically to the left piece by piece, but it is locked to the right. The final detent also takes place at the end of the detent track. Furthermore, any possible manipulation of the closure 10 are made considerably more difficult. Ultimately, this detent is a safety-enhancing, supportive principle. The click sound also gives the consumer their own control over the unsealing process. It will be appreciated that a closure for container for visualizing a previous opening preferably has a cap-shaped inner part 20 with an end face 22 and a peripheral wall 25, wherein the wall 25 is provided with an internal thread 28 which engages with an external thread 18 of the container 12 can be brought. A cap-shaped Außenteii 50 overlaps the inner part 20 and has an end face 52 and a circumferential wall 55, wherein the inner part 20 is rotatably mounted with at least one annular flange 32 in the wall 55 of the outer part 50. In order to be able to display the opening state of the container, the outer part 50 has at least one outer surface 51 a viewing opening 68, 68 ', while the inner part 20 carries at least two differently shaped visible surfaces 41, 42 on its outer surface facing the viewing opening 68 of the outer part 50. In addition, between the wall 25 of the inner part 20 and the wall 55 of the outer part 50 at least one coupling device 80 is formed which fixes the inner part 20 and the outer part 50 after the first opening of the container 12 in a defined angular position to each other, wherein on the visible surfaces 41, 42 in the viewing opening 68, 68 ^* the angular position of the inner part 20 relative to the outer part 50 visually and / or tactively recognizable.

All of the claims, the description and the drawings resulting features and advantages, including design details, spatial arrangements and method steps may be essential to the invention both in itself and in various combinations.
