Description

The subject of the present invention forms a safe capsule with locking strips for with necks provided containers.

Capsules of this type, of which numerous embodiments above all, must allow a successful first Opening the capsule itself to determine the ver need before any falsification of the contents of the Be to protect containers. These capsules must also have one Provide protection against unwanted opening, for example against the opening by children who ge to the contents of the container long, which is often toxic or definitely dangerous is. Generally, attempts are made to use these capsules Gimmicks that only open in a combination of multiple movements.

The studies carried out on the realization of such capsules aim to make the capsules themselves lighter and easier more economical to manufacture and assemble, and easily by automatic machines on the neck of the container ters, which they are supposed to close, can be made attachable.

The purpose of the present invention is therefore that of entanglement to achieve these capsules in an optimal way by a capsule is supplied with a lock is provided, which provides secure protection against offers undesired opening, which is easier and more economical  is economical, and at the same time light and quickly by automatic machines on the neck of the Containers that they are supposed to hold can be put on.

This and other purposes are all achieved through the containing capsule of the type:

• - A first, the actual closure of the container bil the cylindrical element;
• - A second cylindrical element which is coaxial to the first cylindrical element is arranged and allows provide protection against unwanted opening;

Further properties and advantages of the invention are clear licher from the detailed description of an advanced,  however not the exclusive form of realization of the be capsule, which is purely an example and not be is illustrated in the accompanying drawings by to them

• - Fig. 1 shows a section in the vertical position of the capsule concerned;
• - Fig. 2 shows a section of the capsule concerned, leads out to the horizontal plane 11-11 from Fig. 1.

The capsule in question contains a first cylindrical element ( 1 ), which forms the actual closure of the container and serves to close the container itself after the first opening has taken place. The element ( 1 ) is generally injection molded from a rather hard plastic material and is provided in the embodiment shown in the figures with an internal thread that is screwed onto an external thread, which is normally provided on the neck of the container and by Stan dardausführung is.

On the outer side wall of the element ( 1 ), a number of first teeth ( 6 ) are worked on, which are arranged along the lines, and one side of which is connected to the outer wall itself. On the upper outer wall of the element ( 1 ) there are a number of first elevations ( 8 ) which are arranged radially on a circular ring. On this upper outer wall is also a truncated cone-shaped projection ( 9 ), which is located within the elevations ( 8 ) and is coaxial to the element ( 1 ).

The capsule is provided with a second cylindrical element ( 2 ), also injection-molded from plastic, which is arranged coaxially on the first cylindrical element, so that it is placed over the latter.

On the inner side wall of the element ( 2 ) a number of second teeth ( 7 ) are worked, which are arranged along the genera gene, and one side of which is connected to the inner wall itself. The teeth ( 7 ) engage in the teeth ( 6 ) worked on the element ( 1 ) and their arrangement is such that they form a kind of lock together with the teeth ( 6 ), so that thanks to the interconnected sides of the teeth ( 6 ) and ( 7 ) the corresponding rotation between the element ( 2 ) and the element ( 1 ) in the counterclockwise direction is possible, while the corresponding rotation in the clockwise direction is prevented between the same two elements. In other words, the presence of the teeth ( 6 ) and ( 7 ) allows the capsule to be screwed (clockwise rotation) onto the neck of the container, but it prevents unscrewing (counterclockwise rotation) since the interconnected sides of the Slide teeth over one another and prevent pulling into the rotation of element ( 1 ) when element ( 2 ) is rotated.

In order to facilitate the sliding of the sides of the teeth ( 7 ) over the sides of the teeth ( 6 ) it is provided that the side wall of the element ( 2 ) corresponding to each of the teeth ( 7 ) has a section of lesser thickness in relation to the thickness of the remaining part of the surface. In this way, the possibility of elastic deformation of this section is increased and consequently the sliding of the teeth ( 7 ) over the teeth ( 6 ) is facilitated.

It should be noted that in the event of an attempt to open the container by simply rotating the element ( 2 ), which a small child could do, for example, to access the contents of the container itself, the elastic return of the section of lesser strength, which occurs when the contact between the connected sides of the teeth ( 6 ) and ( 7 ) ceases, causes the teeth ( 7 ) to hit the outer wall of the element ( 1 ), with the production of a Noise that can serve as an acoustic indication of the attempt to open the container.

On the upper inner wall of the element ( 2 ) a number of second elevations ( 10 ) are worked, which are arranged radially on egg NEM circular ring, which is accordingly to the circular ring on which the first number of elevations ( 8 ) is arranged. On this upper inner wall there is also an annular flexi ble projection ( 11 ) which bears against the frustoconical projection ( 9 ) when the element ( 2 ) is placed over the element ( 1 ). The height of the annular projection ( 11 ) is such that the number of the first elevations ( 8 ) is kept at a slight distance from the number of the second elevations ( 10 ).

When simply rotating the element ( 2 ), the elevations ( 10 ) do not touch the elevations ( 8 ).

On the other hand, if a slight pressure is exerted on the element ( 2 ) from above, the annular projection ( 11 ) bends when sliding on the side surface of the frusto-conical projection ( 9 ) and enables the upper wall of the element ( 2 ) to approach it top wall of the element ( 1 ). If the element ( 2 ) is then rotated, the elevations ( 10 ) interact with the elevations ( 8 ) and connect the element ( 1 ) in rotation with the element ( 2 ), which is why unscrewing the capsule and thus that Opening is enabled.

If the application of pressure to the upper part of the element ( 2 ) ceases, the elastic setback of the annular projection ( 11 ) removes the upper wall of the element ( 2 ) from the upper wall of the element ( 1 ), so that intermeshing between the elevations ( 10 ) and the elevations ( 8 ) is prevented.

In order to promote the elastic deformation of the annular projection ( 11 ), a number of incisions ( 12 ) are provided, which are arranged along the generatrix of the projection ( 11 ) itself.

To sum up what has been said above, thanks to the interlocking of the teeth ( 6 ) and ( 7 ), the capsule is screwed onto the neck of the container even if only the element ( 2 ) is turned clockwise while unscrewing the Capsule can only take place if the capsule is pressed and the element ( 2 ) is rotated counterclockwise, since it is necessary to unscrew the elevations ( 10 ) and the elevations ( 8 ).

The capsule in question also contains an annular element ( 3 ), which in turn contains a first ring ( 15 ), a second ring ( 16 ) and an additional element ( 17 ).

The first ring ( 15 ) engages inside and below in the first cylindrical element ( 1 ), while the second ring ( 16 ), which is connected by break points coaxially with the first ring ( 15 ), forms the sealing strip of the capsule. The ring ( 16 ) actually positions itself at the moment the capsule is screwed onto the neck of the container below an annular element with which the necks of the containers are normally provided, which is why it generates the capsule in its movement of lifting off the container by unscrewing the capsule itself, cannot follow. If the capsule is unscrewed for the first time, the breaking points that connect the ring ( 15 ) to the ring ( 16 ) break and there is evidence that the container has been opened for the first time.

The additional element ( 17 ) has a diameter which is less than the smallest inside diameter of the ring-shaped element ( 1 ). The element ( 17 ) is coaxially connected by breaking with the annular element, in particular with the ring ( 16 ), so that it can easily be released from the ring ( 16 ) ge, either during the manufacture of the capsule or during the Screw the capsule onto the container.

The additional element ( 17 ), which is injection molded in one piece with the annular element ( 3 ), can take various forms, each of which has a specific purpose. In the example shown in the figure, the element ( 17 ) is shown as a kind of disc, which is positioned in the inner upper part of the element ( 1 ) when it is released and acts as a seal. For this purpose, an internal annular groove ( 19 ) is provided in the upper part of the cylindrical element ( 1 ), which receives the peripheral part of the additional element ( 17 ).

The additional element ( 17 ) can also have the shape of a droplet spout, a drip catcher or still other shapes. In this case, the element ( 17 ) fits into the neck of the container and remains connected to it.

The particular form of realization shown also allows, in addition to the closure securing strip and the additional element being injection-molded in one piece, the work for placing the capsule and the additional elements on the neck of the container, which are often carried out with automatic machines. to simplify considerably. For example, if one considers the element in its form as a seal, the process of inserting the seal into the inner upper part of the element will actually be avoided, a process that is generally performed separately from placing the capsule on the neck of the container. The same considerations can also be made about all other elements that could form the additional element ( 17 ).

The capsule in question thus differs from that to known capsules have the advantages that they have a ver final security strips and effective protection against un has the desired opening, and that it is possible, be it during the manufacturing phase as well as when placing on the Neck of the container to hold the capsule to have an additional element without the additional manufacture of an element or an additional assembly process of the To have to do the element itself.

Numerous changes of a practical nature can be made to the invention be made in the construction details, however without  out of the scope of the claimed inventive idea approach.
