Problems solved by technology

As a result, when the internal pressure of the bottle increases, it can occur that the closure element is pushed out of the mouth region of the bottle until the closure element loses its hold and possibly comes off completely.

Embodiment Construction

[0008] The closure element 1 shown has a bung 3 which can be introduced into the mouth of the bottle. Connected to the plug is a head 5 whose outer diameter is larger than that of the plug 3 . For example, the outer diameter of the head 5 can be provided substantially corresponding to the outer diameter of the bottle in the region of the mouth, so that the bottle almost merges into the closure element. The plug 3 and the head 5 are preferably designed in one piece.

[0009] In the transition region between the plug 3 and the head 5 there is a seal 7 which has at least one first sealing region 9 which abuts against the plug 3 . As shown in the figures, it is preferred to provide a second sealing area 11 immediately above the first sealing area, which abuts against the head 5 from below.

[0010] In this case, a sealing bead 13 is provided on the outer side of the first sealing region 9 facing away from the stopper 3 , which seals the interior of the bottle from the environmen...

Abstract

The invention relates to a closing element for bottles, comprising a stopper (3), which engages in the neck of the bottle, and a head (5) whereby the external diameter thereof is greater than the stopper, in addition to a sealing element (7) which is arranged in the transition area between the stopper and the head, and a first sealing area (9), which is in contact with the stopper, comprising at least one sealing bulge (13) which is oriented towards the outside. The closing element is characterised in that the first sealing area (9) comprises at least one projection, which is oriented towardsthe outside, or at least one annular-shaped bulge (15) which is arranged on the side of the annular bulge (13) which is opposite the head and at a distance in relation thereto, and at least one recess which is arranged in the periphery of the bulge.

Description

technical field [0001] The invention relates to a closure element for a bottle having a bung which fits into the mouth of said bottle and a head with a larger outer diameter than the bung and a seal arranged between the bung and the head In a transition region therebetween and with a first sealing region abutting the bung, said first sealing region comprising at least one outwardly directed sealing protrusion. Background technique [0002] Closing elements of the type discussed here are known. They are used in particular in bottles with high-value contents, in particular bottles made of glass. In order to ensure a hermetic closure of the contents of the bottle, a seal is provided. After closure at the manufacturer, closure elements of the type in question are usually protected, for example by a plastic or aluminum cap which holds the closure element on the bottle. After the first opening, ie after removal of the cap, the closure element is held by friction between the sea...
