Problems solved by technology

However, container closures are generally not easily tightened by users, especially by young and old users
In addition, sufficient sealing force can only be obtained by providing threads with a small pitch angle on the container closure and container neck, which causes the sealing torque acting on the container closure to be leveraged on the container lip and container closure. Creates a strong downward seal between the bases of the cap

Embodiment Construction

[0058] Referring to Fig. 1, the container closure assembly includes a container neck 1 and a container closure 2, the container closure 2 is provided with a base 3 and a peripheral skirt 4 provided with threads, and the terminal of the container neck 1 is a smooth Lip 5. As shown in the "Prior Art" section on the left side of Figure 1, in prior art container closure assemblies, the lip 5 and resilient gasket 6 form a compression seal.

[0059] The container neck 1 is injection molded from polyethylene terephthalate (PET), and the container cover 2 is integrally injection molded from polyethylene. As disclosed in detail in the European patent application EP-A-1446332, the container neck 1 and the container closure 2 are respectively provided with integrally formed, fast-rotating, large-pitch angle thread lines with pressure safety features. European patent application EP-A-1446332 The entire content of the application is incorporated by reference.

Abstract

A container closure assembly comprising a threaded closure with a sealing plug (24) and a sealing skirt (20) pinching a container lip (5). The skirt and the plug comprise sealing ribs (21, 22, 26, 27) that engage the lip of the container. The ribs are located at substantially equal longitudinal distances from the base (3) of the closure.

Description

technical field [0001] The present invention relates to an improved seal for a container closure assembly, which is particularly suitable for sealing gas-liquid containers such as carbonated beverage containers and non-carbonated beverage containers. Background technique [0002] As is well known, glass, paper, metal or plastic beverage containers are generally provided with a screw-on top which is refastenable on the neck of the container. Typically, the container is topped with a screw-on container closure assembly to provide a reliable gas-liquid seal. The fastening of the container closure to the container neck preserves the quality of the beverage both during transport and storage, as well as the remainder of the beverage after consumption. [0003] In the prior art, some container closure assemblies have elastic gaskets on the base of the container closure. When the container closure is fastened on the container neck, the elastic liner is pressed against the lip of t...
