DE895859C - Capsule closure made of elastic plastic for bottles - Google Patents

Description

Elastic closures have recently been used to close bottles made of plastic in use, in which the capsule by a so-called tear-off flap is torn open. This closure is so elastic that it cannot be opened by opening it can be damaged and reused after partial emptying of the bottle ring can be.

These capsule closures have proven themselves very well and delighted increasing popularity.

Lately delivery requests have become known, according to which these Type of closures no longer returned to their original state after being opened for the first time can be, so that the lock once opened can be used for ongoing use used for emptying the bottle, i.e. opening and reclosing, but can never be restored to its original state.

Such a closure is intended to prevent the recipient an original bottle is enabled after the contents of the bottle have been used up to fill the bottle with an inferior quality, again original to close and sell as new goods.

A closure that perfectly fulfills these functions it must also be required that it is flush with the top edge of the bottle, that it has no protruding edges or bumps, which under certain circumstances Damage the cellophane, celluloid, stamniol or shrink capsule, he did can be easily pulled up and that especially the first time it is not opened either creates particular difficulties or requires tools.

The one described in the following description fulfills all of these requirements Closure in an ideal way, and it should therefore suit its purpose in each Turn relationship fair.

The subject matter of the invention is shown in FIGS.

Fig. I shows the section through the bottle with the bottle closure in longitudinal section; Fig. 2 shows the bottle closure in longitudinal section with section through the diving cap; FIG. 3 shows a section A-B through FIG.

The closure consists of an expedient way of thermoplastic Injection molded elastic closure body I. This closure body has two different approaches, so-called bead-like undercuts, which are Press into the grooves in the neck of the bottle when fitting it onto the neck of the bottle.

In contrast to most such closures, the subject of the invention two wart-like undercuts, i.e. thickenings 2 and 3.

In the closure itself, as indicated by 4, there is a sharp-edged one Metal strips inserted.

This sheet metal strip lies on the inner wall except for its two ends 6 of the closure body I flat. {These sheet metal strip ends run through the cutouts 5 through the closure body 7 and lie on the outer wall of the closure body 7 plan on. The outer wall of the closure therefore has a smooth surface and a tinfoil shrink-fit capsule or something similar to be raised.

With 8 the bottle neck is referred to on which the closure is raised.

Opening a bottle with the new cap is very simple. One of the metal strip ends6, which extends through the tinfoil or shrink capsule in its contours becomes right-angled with any sharp object pulled up and with a jerk around the neck of the bottle, causing the Upper and lower part of the bottle closure connecting webs 9 cut through will. Then the immersion cap is removed from the top of the bottle cap, with the designated 10. Flap of the upper part of the closure is ready to hand. This The flap is pulled strongly upwards, the elastic upper part of the fastener is released the bottle opening is pulled down and the bottle is ready to be poured.

After this initial opening, the connecting webs are between The upper part of the closure and the lower part of the closure have been cut through and the metal strip is no longer connected to the lock. The lock can no longer be in Original version can be used. The upper part can, however, be used for closing of the bottle, by gently closing and opening it for so long until the bottle is empty.

Due to the above-described arrangement of the closure, all are desired Effects achieved.

For the production of the above-described closure are suitable especially all thermoplastic, elastic injection materials.
