Problems solved by technology

However, for various reasons, PVC is no longer used as a sealing material for food (especially beverages)
However, the actually used PVC-free sealing materials with a rather high molecular weight have the disadvantage that they are not sufficiently elastic or resilient and do not ensure "resealing" during release and subsequent pressure drop at such high internal pressures
However, they rely on a soft elastic backing material, such as PVC, and cannot be applied to other types of closures, such as crown cork closures for example

Embodiment Construction

[0045] The figures show closures for bottle or other container openings. FIG. 1 shows the basic structure of a bottle cap as an example of a tear-off closure. The closure consists of an upper circular cover plate 1 adjacent to the outside of the cover plate 1 is a substantially cylindrical collar or skirt 2 which is crimped 4 over the neck 3 during the sealing and clamping process. Or surround the bottleneck 3 below the flange. A sealing gasket 5 (which is not visible in FIG. 1 ) is located on the underside of the cover plate 1 and has an annular profile seal 6 on the outer circumferential side. It can also be seen in FIG. 1 that the tear-off closure has a tear-off opening strip 7 with a tongue 8 protruding from the closure skirt 2 , wherein the tear-off strip is arranged on the closure The dashed lines 9, 9' in the limit. The dashes on both sides are generally of the same length, but can vary from half length 9' to full length 9. The tongue 8 is connected to a pulling ele...

Abstract

The invention relates to a closure for a container, especially a bottle, comprising an upper covering panel and a circumferential collar adjoining the panel on the outside, wherein a sealing insert is arranged on the underside of the covering panel which has a circumferential profile seal on the outside. The upper covering panel has at least one partly circumferential embossing which interacts with the profile seal forming a valve.

Description

technical field [0001] The present invention relates to a closure for a container, especially a bottle, comprising an upper cover plate and an annular collar or skirt adjacent the outside of the cover plate, wherein a sealing insert or gasket is arranged along the outer periphery with an annular The underside of the shaped seal cover. Such closures are also known as (closing) caps or (closing) caps. Closures within the scope of the invention are in particular bottle caps which can be configured, for example, as crown cork closures or as tear-off closures. These closures are sealed to the container by a crimping operation. In both cases, the upper cover plate of the closure incorporating the profile seal is pressed against the top of the bottle when the closure is sealed on the bottle. An annular band or collar forming the skirt of the cylindrical closure surrounds the bottle neck crimp after sealing, and the lower portion of the skirt provides a secure grip under the crimp ...
