Problems solved by technology

Also, manufacturers in making these closures and fittings often use too much torque during the initial assembly of the closure onto the fitting, thus damaging the dispensing fitting
When initially fitting the fitting onto the container, too much torque can destroy the bottom fitting and pieces of the fitting can fall into the container
Furthermore, it has been found that with prior art closures, the resistance of the plug or inner seal ring on the inner surface of the neck of the closure or fitting is insufficient when the closure encounters a bump and causes the closure to unscrew slightly. prevent it from unscrewing

Embodiment Construction

[0015] Detailed description of the preferred embodiment

[0016] like figure 1 As shown, a plastic cap or closure 10 of the present invention has been screwed onto the neck 13 of an adapter 12 which is typically fitted to a container for holding liquids, such as soft drinks, fruit juices, etc. on the container. Typically, the closure 10 is made of a harder plastic material than the material of the fitting 12 . The plastic material used to make the closure 10 includes, but is not limited to, polypropylene, and the plastic material used to make the fitting 12 includes, but not limited to, polyethylene. Also throughout the application, the terms "fitting" and "container" and "container neck" are used interchangeably.

[0017] like Figure 2-4 As shown, the sealing member 10 is provided with a top wall 24 and a downwardly extending outer wall 20 , and an inner sealing ring 22 is arranged inwardly from the outer wall 20 at intervals. The outer wall 20 is generally provided wit...

Abstract

A sealing member for fittings, which is provided with an outer sidewall extending downward and spaced from an inner sealing ring, and the outer sidewall adjacent to the top wall is provided with a plurality of mutually spaced inwardly extending Ribs to engage the mouth at the exit from the neck of the fitting.

Description

technical field [0001] The present invention relates to an improved sealing arrangement for a container closure, and more particularly to an improved sealing arrangement for a closure having an inner seal that forms a seal against the inner surface of the neck of a container or fitting ring. Background technique [0002] In the manufacture of containers with dispensing fittings or spouts on top, these fittings are usually provided with a closure, wherein the fitting includes an inner sealing ring connected to a Spaced apart from the exterior of the skirt of the closure member, the neck wall of the dispense fitting is sandwiched between the inner seal ring and the outer skirt of the closure member when in the closed condition. For relatively small closures, such as those used on gable-top cartons for milk, orange juice, and other liquids, the closure and fitting are typically made of a relatively flexible plastic material. Furthermore, manufacturers in making these closures...
