Description

THREADED COVER FOR BOTTLES DESCRIPTION OF THE INVENTION The invention relates to a screw cap for bottles having a safety tape formed by a plug with a bottom, in which a cylindrical shell is disposed which is provided on its inner side with a thread and the safety tape is connected with the envelope through nerves.

Threaded caps for bottles of the initially mentioned type are known (Cf., v. Gr., O 98/15465 Al). These have the objective, on the one hand, of allowing a safe closing of the bottle and, with it, an exit of the liquid that is in the bottle, both before opening it for the first time, as well as after closing it again. In addition, threaded caps should signal the opening of the bottle for the first time, to indicate to the consumer immediately an unauthorized opening of the lid, and draw your attention to a possible extraction of liquid from the inside of the bottle, or its contamination. For this purpose, the security tape is disposed in the enclosure in a destructible manner. When opening for the first time, the tape breaks itself or in the region of the nerves, so that the opening of the bottle is immediately visible even after closing it again.

The known cover closures meet the intended purpose only conditionally. Certainly, they are sealed even after closing again, so that the liquid can not drain from the bottle; but the second requirement for closures, that is, to signal an unauthorized opening and closing, is fulfilled only by insufficient closures. Because there is the possibility of opening the bottle without destroying the safety tape, so that the bottle is closed and provides the impression of the outside if it was not opened after packing in the packer, even though the bottle may have been contaminated in the intermediate within the framework of the opening described in the foregoing. This cancels the function of the security tape.

Here the invention wants to remedy. The invention is based on the objective of creating a screw cap for bottles that prevents an unauthorized and invisible opening and closing of the bottles. According to the invention, this objective is achieved because a cylinder is disposed at the bottom, coaxial with the envelope.

By means of the invention a screw cap for bottles is created which prevents the bottles from opening and closing invisibly. This is guaranteed, because it is prevented, when cutting and heating the bottle neck, thanks to the cylinder arranged coaxial with the envelope, a compress. As a result, a reduction in the diameter of the bottle thread is prevented and, therefore, the safety tape is passed without destroying it. Rather, an extraction, still in a hot state and cut off from the bottleneck, causes a destruction or breakage of the safety tape, so that the safety tape meets its objective.

In conditioning the invention, the cylinder is hollow. This hollow embodiment of the cylinder entails, on the one hand, an economical production, on the other the weight of the closure is comparable with closures known from the state of the art thanks to the reduced requirement of material for the cylinder.

Advantageously, the cylinder is closed on the side facing away from the bottom. The closed realization of the cylinder. It offers greater stability compared to the open realization. This has the consequence that even with a strong heating of the bottle neck with the screwed cover a deformation is prevented to a good degree, for which reason the safety is increased additionally against unauthorized opening and re-closing.

Preferably, the cylinder has a thread. Providing a thread in the cylinder leads to an additional increase in the stability of the closure in the closed state.

The thread may be, or else, a self-tapping thread that cuts the bottle neck when first screwing the closure into the bottle; in modification, a thread can also be provided by the manufacturer in the internal part of the bottleneck which corresponds, then, to the thread provided in the envelope.

The object of the invention is furthermore solved by means of a screw cap for bottles having a security tape, in which the closure is wrapped by a shrink film. Thanks to the use of the contraction sheet, an opening of the bottle is almost impossible without destroying the contraction sheet; insofar as it could be achieved to open a bottle without destroying the shrinkage sheet, there is then no possibility to re-arrange the sheet without visible change in the bottle, so that the consumer immediately notices the opening made of the bottle.

Other improvements and arrangements of the invention are indicated in the other subordinate claims. An exemplary embodiment of the invention is shown in the figure and is described in detail below. It shows: Fig. 1 an axial section through a screw cap; Fig. 2 an axial section through a screw cap in other packaging Fig. 3 an axial section by a screw cap in other packaging The threaded cap 1 for bottles selected as an example of embodiment is provided with a safety tape 2. The threaded cap 1 is formed by a plug 3 having a bottom 31. In the bottom 31 is disposed a cylindrical shell 32. The envelope 32 is provided on its inner side with an internal thread 33.

The casing 32 of the threaded cover 1 is connected by ribs 4 to the safety tape 2. On the inner side of the safety belt 2, retaining cams 21 are arranged which engage, in the screwed-in state of the lid 1 in a bottle, behind a rib arranged on the neck of the bottle. The retaining cams 21 are provided on the side, facing away from the bottom 31, with bevels 22 that allow a screw without destroying the lid on the bottle. The side of the retaining cams 21 which is oriented towards the bottom 31 of the plug 3, on the other hand, is carried out substantially horizontally, so that, when opening the lid 1, these are trapped in the rib arranged in the neck of the bottle, so that a correct opening of the bottle is possible only by deliberate destruction of the safety belt 2.

In bottom 31 of plug 3 is found arranged, coaxial with the casing 32, a cylinder 5. The height of the cylinder 5 essentially corresponds to the height of the safety band 2 in connection with the ribs 4 and with the casing 32. The cylinder 5 is therefore projected, to the nerve area of the bottleneck. The outer diameter 5 essentially corresponds to the inner diameter of the bottle neck, so that the bottle neck with its thread is guided in the screwed state between the casing 32 of the plug 3 and the cylinder 5.

In the exemplary embodiment, the cylinder 5 is made hollow. On its side, facing away from the bottom 31, it is closed by a floor 51. In the exemplary embodiment according to FIG. 2, the cylinder 5 has an external thread 52. The external thread 52 can be made self-tapping and therefore cut on the inner side of the bottle neck when being screwed. But it can also correspond to a thread provided on the inner side of the bottle neck. In this case, the pitch of the thread provided on the inner side of the bottle neck corresponds to that of the internal thread 33 of the plug 3.

The threaded cover 1 shown in the exemplary embodiment according to FIG. 4 is also provided with a safety tape 22. It also consists of a plug 3 that is made in a manner comparable to the example of embodiment according to FIG. 1. Likewise, ribs 4 are provided between the cap 3 and the safety belt 2. However, the threaded cap shown in the exemplary embodiment according to FIG. 4 is made without a cylinder. Rather, the lid 1 is wrapped by a shrinking sheet 7. As shown, the shrinking sheet 7 extends on the outer side of the bottle and covers the lid 1 and the bottleneck outlined.

The inventive threaded cap 1 with cylinder 5, arranged inside, prevents crushing of the bottle neck, including the thread, to remove the thread of the bottle neck without destruction of the safety belt 2. Thanks to the outside diameter of the cylinder 5 which corresponds essentially to the diameter of the cylinder 5, a deformation -in the sense of a reduction in diameter-is practically excluded. In the exemplary embodiment according to FIG. 2, a positive connection is also created because of the external thread 52 provided in the cylinder 5, which further complicates the removal of the thread from the bottle neck without destruction of the safety belt 2 .

In the exemplary embodiment provided with a shrinking sheet 7, the consequence of unscrewing the screw cap 1 is a destruction of the shrinking sheet 7. To the extent that it is possible, however, to open the screw cap 1 without destroying the sheet 7 of In principle, it is possible to re-close the bottle with the screw cap 1 and the shrinking sheet 7, but visible traces remain on the sheet that allow the consumer to detect immediately what is involved here. of a bottle already open.
