Abstract
A swing-lid closure (30; 100; 200) for containers, having a closure body (32; 214) which, on its top side, has an annular shoulder (42; 108; 212) and a through-passage channel (38) which opens out in an outlet opening (50), having a swing lid (34; 114; 208) with a lid shell (48; 112; 216) of a hinge (56) can be pivoted between a closed position and an open position, having a radial depression (58; 118; 220) of the lid shell (48; 112; 216), which is provided on the front side of the swing lid (34; 114; 208) and extends over part of the circumference of the swing lid (34; 114; 208), having a tamperproof securing strip (60; 104; 204) which extends in the circumferential direction on the annular shoulder (42; 108; 212) of the closure body (32; 214) and has its bottom edge fastened on the annular shoulder (42; 108; 212) via predetermined breaking points (64) and, in the original closed position of the swing lid (34; 114; 208), projects up into the depression (58; 118; 220) of the lid shell (48; 112; 216) in an arcuate manner, and, for the purpose of forming a tear-off opening (66), the circumferential length of the depression (58; 118; 220) of the lid shell (48; 112; 216) is greater, at least in a circumferential direction of the lid shell (48; 112; 216), than the circumferential length of the tamperproof securing strip (60; 104; 204). In its position which indicates the intact state, the tamperproof securing strip (60; 104; 204) is secured by a device (68; 70; 72; 74; 76; 78; 80; 82; 106; 108; 110; 202; 206; 210) by means of which the tamperproof securing strip (60; 104; 204) is connected in a form-fitting and/or force-fitting manner to the swing lid (34; 114; 208). This results in the tamperproof securing strip being better safeguarded against manipulation.

Description

The invention relates to a swing-lid closure for containers containing free-flowing material, comprising

    • a closure body which can have its bottom, open end connected to the container via an opening of the latter and, on its top side, has an annular shoulder and a through-passage channel for the free-flowing material, the through-passage channel being connected to the interior of the container and opening out in an outlet opening,
    • a swing lid with a lid shell, which is articulated on the periphery of the top side of the closure body by a hinge such that it can be swung between a position in which it partially engages over the closure body and closes the outlet opening and a position in which it exposes the outlet opening,
    • a radial depression of the lid shell, which is provided on the front side of the swing lid, the front side being located opposite the hinge, and extends over part of the circumference of the swing lid,
    • a tear-off tamperproof securing strip which extends in an arcuate manner in the circumferential direction on an outer periphery of the annular shoulder of the closure body and has its bottom edge fastened on the annular shoulder via predetermined breaking points and, in the original closed position of the swing lid, projects up into the depression of the lid shell in an arcuate manner over part of the circumference of the closure body, the depression of the lid shell having a circumferential length which, at least in a circumferential direction of the lid shell, is dimensioned to be greater than the circumferential length of the tamperproof securing strip, for the purpose of forming a tear-off opening for the tamperproof securing strip.

Swing-lid closures in front of the abovementioned generic type belong to the prior art and are often used for containers or bottles which are intended for goods for mass consumption, such as free-flowing body-care products, e.g. skin lotion, bath gel or skin oil, or for household and kitchen care products, e.g. furniture polish or cleaning agents for cooking utensils, or for substances used for adding to or seasoning food, e.g. ketchup or soy sauce. Such swing closures with a tamperproof securing means are also used for materials in drug stores and pharmacies, in order to make it obvious that such packs comprising a container and swing closure have been manipulated without authorization. Tamperproof securing means for such swing closures, which constitute mass-produced articles, have to be capable of being produced cost-effectively and, in particular have to ensure a high level of reliability for the tamperproof securing means. It is thus an aim to improve the tamperproof securing means for such swing closures further.

The object of the invention is thus to improve the extent to which such containers equipped with a tamperproof securing strip are safeguarded against manipulation, to the effect that the tamperproof securing strip cannot be gripped at its top edge, and bent outward around the predetermined breaking points, with or without the aid of a tool-like article, without the predetermined breaking points, which connect the tamperproof securing strip to the closure body, being destroyed.

The invention achieves this object in that, in its vertical position, which indicates the intact state and in which it is protected in the depression of the swing lid, the tamperproof securing strip is secured by a retaining device and connected in a form-fitting and/or force-fitting manner to the swing lid.

This considerably improves the extent to which the swing-lid closure is safeguarded against manipulation because it is virtually impossible to open the swing-lid closure without this being obvious, i.e. without destroying the predetermined breaking points which connect the tamperproof securing strip to the closure body and without the tamperproof securing strip being separated off from the closure body as a result.

According to a first embodiment of the invention, at least one snap-in hook projects radially outward, in relation to the main axis of the swing closure, from the bottom edge of the lid shell, which forms the radially inner rear wall of the depression. The tamperproof securing strip is provided, in the region of its bottom edge, with at least one latching edge for the snap-in hook. Furthermore, at least one locking opening is provided on the underside of the gripping ridge of the swing lid, this at least partially enclosing the top edge of the tamperproof securing strip. In a further configuration of this first embodiment, at least one locking pin projects up from the top edge of the tamperproof securing strip, at least one corresponding locking opening being provided in the underside of the gripping ridge of the swing lid. The tamperproof securing strip is fastened on a radially outer, axially offset, arcuate stepped portion of the annular shoulder of the closure body, the radial width of this corresponding approximately to the sum of the radial widths of the tamperproof securing strip and of the snap-in hook on the lid shell. It is possible for the gripping ridge to extend more or less over a semicircle, and, in the intact position of the swing lid, to cover over at least the top edge of the tamperproof securing strip and to be aligned with the circumferential surface of the same.

According to a second embodiment, retaining elements are integrally formed on the inside of the tamperproof securing strip, the retaining elements extending radially inward and the swing lid resting thereon, by way of its lid shell in the closed position of the swing lid. It is possible here for the retaining elements to be U-shaped and to engage around the lid shell of the closed swing lid, in which case one of the two U-legs is formed by the tamperproof securing strip, from the bottom edge of which a U-crosspiece extends radially inward as a support for the lid shell and merges into the second U-leg, which extends parallel to the radially inner surface of the tamper proof securing strip. The U-shaped retaining elements are advantageously arranged on both sides of the snap-in hook.

According to a third embodiment, the at least one latching edge of the tamperproof securing strip with the at least one snap-in hook of the swing lid may be formed by at least one latching tongue which, as an integral constituent part of the tamperproof securing strip, extends radially inward in the direction of the annular shoulder of the closure body and the free end of which terminates at an axial distance from the annular shoulder. That side of the snap-in hook which is directed toward the latching edge is preferably arranged level with the bottom edge of the lid shell, the height of this bottom edge being reduced by the height of the snap-in hook. It is further advantageous if at least one radially inwardly set-back portion of the lid shell is provided, in the region of the radial depression thereof, with at least one radially outer latching shoulder, which engages beneath the latching edge of the latching tongue of the tamperproof securing strip in the closed position of the swing lid.

In a further configuration of this third embodiment, it is recommended for the radially set-back portion of the lid shell to be designed as an axis-parallel guide groove for the latching tongue of the tamperproof securing strip and to be offset radially inward to an extent which corresponds approximately to the sum of the radial dimensions of the tamperproof securing strip with its latching tongue and the snap-in hook of the swing lid. It is further advantageous if the bottom edge of the latching shoulder, this bottom edge being directed toward the closure body, is aligned with the bottom edge of the lid shell.

FIGS. 1 to 8 illustrate the first embodiment of the swing-lid closure 30 for bottles or containers which contain free-flowing material, are known per se and are thus not shown. The swing-lid closure 30 comprises a closure body 32 which can have its bottom, open end connected to the container via an opening of the latter and, on its top side, has an annular shoulder 42 and a through-passage channel 38 for the free-flowing material, the through-passage channel being connected to the interior of the container and opening out in an outlet opening 50.

Also provided is a swing lid 34 with a lid shell 48, which is articulated on the periphery of the top side of the closure body 32 by a hinge 56 such that it can be swung between a position in which it partially engages over the closure body 32 and closes the outlet opening 50 and a position in which it exposes the outlet opening 50. A radial depression 58 of the lid shell 48 is provided on the front side of the swing lid 34, this front side being located opposite the hinge 56, and extends over part of the circumference of the swing lid 34.

A tamperproof securing strip 60 extends in an arcuate manner in the circumferential direction on an outer periphery of the annular shoulder 42 of the closure body 32 and has its bottom edge fastened on the annular shoulder 42 via predetermined breaking points 64. In the original closed position of the swing lid 34, the tamperproof securing strip 60 projects up into the depression 58 of the lid shell 48 in an arcuate manner over part of the circumference of the closure body 32, the depression 58 of the lid shell 48 having a circumferential length which, at least in a circumferential direction of the lid shell 48, is dimensioned to be greater than the circumferential length of the tamperproof securing strip 60, for the purpose of forming a tear-off opening 66 (FIG. 4) for the tamperproof securing strip 60.

A cap shell 36 of the closure body 32 is provided, on the inside, with fastening means, in the present exemplary embodiment with a thread 40 by way of which the closure body 32 can be screwed on to a corresponding external thread on a container neck enclosing the opening. Of course, as is known per se, other fastening methods such as clip-in protuberances, welding, or forming the container and closure body integrally are likewise possible. At the bottom end of the cap shell 32, in a manner known per se, an encircling tamperproof securing strip 41 is fastened, via one or more predetermined breaking points (not shown), with inner protuberances 43, which engage beneath an annular bead on the neck of the container and secure the tamperproof securing strip 41 if the closure body 32 is unscrewed from the container neck.

The annular shoulder 42 bounds the top end of the cap shell 36 and merges into a tubular outlet nozzle 44 which forms the through-passage channel 38. The outlet nozzle 44 is tapered conically to a slight extent in the direction of its outer, free end and can thus also be used as a drinking nozzle.

On the underside of the annular shoulder 42, an encircling sealing lip 46 which is directed obliquely inward toward the container is provided at a radial distance from the inside of the cap shell 36 for the purpose of sealing the closure body 32 in relation to the end surface of the container neck.

The swing lid 34 engages, by way of the lid shell 48 over the top, outer end of the closure body 32, this end being formed by the outlet nozzle 44, and is provided with the outlet opening 50 (FIGS. 1 and 3), which is arranged coaxially in relation to the through-passage channel 38 of the closure body 32. The swing lid 34 also engages, by way of a tubular stub 54 which projects down from the underside of a head wall 52, over the outlet nozzle 44 of the closure body 32 and butts with sealing action, by way of its inner circumferential surface, against the outer circumferential surface of the outlet nozzle 44.

The swing lid 34 is connected integrally to the closure body 32 by the hinge 56 and is arranged such that it can be pivoted between the closed position, which is shown in FIGS. 3, 6 and 7 and an open position which is shown in FIGS. 1, 2, 4, 5 and 8 and in which the outlet opening 50 of the outlet nozzle 44 is exposed.

The tamperproof securing strip 60 projects vertically, i.e. in an axis-parallel manner to the main axis of the swing-lid closure 30, but in an arcuate manner in the circumferential direction of the same, into the correspondingly shaped depression 58 of the lid shell 48, such that the outer circumferential surface of the tamperproof securing strip 60 is located within an outer enveloping surface of the swing closure 30 and thus does not make it any more difficult for the swing closure 30 to be either produced or fitted.

According to the invention, in its vertical position, which indicates the intact state and in which it is protected in the depression 58 of the swing lid 34, the tamperproof securing strip 60 is secured by a device by means of which the tamperproof securing strip 60 is connected in a form-fitting and/or force-fitting manner to the swing lid 34.

According to the first embodiment, the securing device comprises, inter alia, two snap-in hooks 68 which project radially outward, in relation to the main axis x of the swing-lid closure 30, from the bottom edge 62 of the lid shell 48, which forms the inner rear wall of the depression 58. The tamperproof securing strip 60 is provided, in the region of its bottom edge 62, with two latching edges 70 for the snap-in hooks 68, these being formed by rectangular cutouts 72 of the bottom edge of the tamperproof securing strip 60. Of course, it is also possible to provide just one snap-in hook 68, or more than two snap-in hooks 68, on the swing lid 34 and a corresponding number of latching edges 70 on the tamperproof securing strip 60.

The securing device of this embodiment also includes a top edge 76 of the tamperproof securing strip 60 being anchored in the gripping ridge 74 of the swing lid 34. For this purpose, preferably two locking pins 78 project up from the top edge 76 of the tamperproof securing strip 60. Accordingly, for the engagement of the locking pins 78, two corresponding, pocket-like locking openings 80 are provided in the underside of the gripping ridge 74 of the swing lid 34. In the original closed position, the two locking pins 78 thus engage in the two locking openings 80, while the lower-level top edge on either side of the locking openings 80 of the tamperproof securing strip 60 butts directly against the planar underside of the gripping ridge 74 and, by means of the gripping ridge 74 which projects outward beyond the tamperproof securing strip 60 is protected against unauthorized manipulation. This locking of the tamperproof securing strip 60 at its top edge 76 is offset on both sides in relation to the snap-in-hook locking 68, 70 as can clearly be seen from FIGS. 1, 4 and 8. Since the snap-in hook 68 engages beneath the tamperproof securing strip 60 at the latching edge 70, the top edge 76 and the locking pins 78 are permanently and reliably enclosed in the locking openings 80 of the gripping ridge 74. Depending on the respective use conditions and on the size of the swing-lid closure, it is thus possible to use at least one locking pin with at least one associated locking opening, that is to say a single locking opening can form an arcuate longitudinal groove for the engagement of the entire top edge, located on the same level, of the tamperproof securing strip 60.

It can be seen that, in this way, it is also the case that the top edge 76 of the tamperproof securing strip 60 is not accessible with the aid of tool-like equipment and the tamperproof securing strip 60 can only be removed, for the purpose of opening the swing lid 34, as a result of its predetermined breaking points 64 being destroyed. Consequently, it is virtually impossible to gain unauthorized access to the contents of the container without the destruction or removal of the tamperproof securing strip 60 being obvious.

This stable anchoring of the top edge 76 of the tamperproof securing strip 60 is preferably, and significantly, assisted in that the tamperproof securing strip 60, as a result of being curved in the circumferential direction, is resistant to being bent outward, but is also fastened on a radially outer, axially offset, arcuate stepped portion 82 of the annular shoulder 42 of the closure body 32, the radial width of this corresponding approximately to the sum of the radial widths of the tamperproof securing strip 60 and of the snap-in hook 68 on the lid shell 48. As a result, the snap-in hook 68, which engages beneath the latching edge 70, is secured between the approximately axis-parallel circumferential surface 84 in FIG. 3 of the annular shoulder 42, this circumferential surface bounding the stepped portion 82 in the radially inward direction, and the inside of the tamperproof securing strip 60, i.e. it cannot be pushed or moved radially inward in order to be unlocked.

The gripping ridge 74, located diametrically opposite the hinge 56 extends more or less over a semicircle, and, in the intact position of the swing lid 34 covers over, as has been described above, at least the top edge 76 of the tamperproof securing strip 60 and, according to FIG. 3, projects outward to a large extent, in a protective manner beyond the tamperproof securing strip 60.

FIGS. 9 to 15 illustrate the second embodiment of a swing-lid closure 100 according to the invention, in which case, in order to avoid repetition, the same parts are not described anew, and use is made of the designations which were utilized for the first embodiment.

In the case of the present second embodiment, two retaining elements 102 which are of U-shaped configuration, are provided for a tamperproof securing strip 104. The upwardly projecting tamperproof securing strip 104 here forms one of two legs of the U-shaped retaining elements 102. A horizontal crosspiece 106 of the U-profile of the retaining elements 102 extends radially inward from the inside of the tamperproof securing strip 104, in the region of the bottom edge of the latter and approximately parallel to an annular shoulder 108, and bears a second leg 110 parallel to, and at a sufficient distance from, the tamperproof securing strip 104, so that the U-shaped retaining elements 102 each engages around a lid shell 112 of a closed swing lid 114 from the bottom edge thereof, as can clearly be seen from FIG. 14. The radially inwardly extending, horizontal U-crosspiece 106, which is approximately parallel to the annular shoulder 108, forms the support for the lid shell 112 here. Of course, it is also possible, if appropriate, to provide just a single retaining element 102 of appropriate dimensions.

According to a variant of this second embodiment, it may be sufficient, in certain circumstances, if only the U-crosspiece 106 of the retaining elements 102 extends radially inward and the leg 106 is omitted, with the result that an L-profile is formed in cross section with the tamperproof securing strip 104. In this case, the lid shell 112, in its closed position, rests on the horizontal leg or crosspiece 106 of the L-profile and retains the tamperproof securing strip 104 in its position in which it projects up from the annular shoulder 108 within a depression 118 beneath a gripping ridge 120.

FIGS. 16 to 22, show the third embodiment of a swing-lid closure 200, in the case of which at least one latching edge 202 of a tamperproof securing strip 204 for at least one snap-in hook 206 of a swing lid 208 is formed by at least one latching tongue 210. The latching tongue 210 is formed as an integral constituent part of the tamperproof securing strip 204 and extends radially inward, and downward in the direction of an annular shoulder 212 of a closure body 214, from the top side of the tamperproof securing strip 204. The free end of the latching tongue 210 terminates at an axial distance from the annular shoulder 212. That side of the latching edge 202 which is directed towards a swing lid 208 is beveled radially inward in the direction of the annular shoulder 212 of the closure body 214 and that side of the at least one snap-in hook 206 which is directed toward the latching edge 202 are beveled correspondingly. That side of the snap-in hook 206 which is directed toward the latching edge 202 is arranged level with the bottom edge 226 of the lid shell 216, the height of this bottom edge being reduced by the height of the snap-in hook 206 (FIG. 22).

The snap-in hook 206 is arranged in a radially inwardly set-back U-shaped portion 218 which forms an axial guide groove 224 in the lid shell 216 for the latching tongue 210 is provided, in the region of a radial depression 220, with at least one radially outer latching shoulder 222, which engages beneath the latching edge 202 of the latching tongue 210 of the tamperproof securing strip 204 in the closed position of the swing lid 208 (FIG. 22). The axis-parallel guide groove 224 for the latching tongue 210 of the tamperproof securing strip 204 is offset radially inward to an extent which corresponds approximately to the sum of the radial dimensions of the tamperproof securing strip 204 with its latching tongue 210 and the snap-in hook 206 of the swing lid 208. In the closed position, the latching tongue 210 locks the latching hook 206, with elastic prestressing, on the stepped portion 82 in a force-fitting and form-fitting manner in relation to the outside 84 of the annular shoulder 212, with the result that, as a result of the gripping ridge 74 engaging over the top edge of the tamperproof securing strip 204, unauthorized bending out of the tamperproof securing strip 204 without the predetermined breaking points being destroyed is virtually impossible.
