DETAILED DESCRIPTION OF THE DRAWINGS

[0041]FIG. 1 illustrates a plan view of a container 1, and end wall 2, such as an aluminum beverage container, with a major portion of a cover 10, removed for clarity, having a permanently attached resealable device, manufactured of a suitable elastomeric components, incorporating the principles of this invention.

[0042] Referring to FIGS. 1, FIG. 2, a preferred embodiment of this invention is shown positioned and attached to a beverage container 1 having an end wall 2, and aperture 3.

[0043] Into aperture 3, is inserted, in circumferential sealing engagement, rim seal 5, having a depending wall engaging the marginal edge defining aperture 3, in an annular locking recess 4.

[0044] The inwardly open circumference of rim seal 5 is formed to incorporate a taper 21, dimensioned such as to have one diameter open toward the exterior of container 1, and a larger diameter open to the interior of container 1. A small diameter gas vent hole 9, communicates...

Abstract

A closure set within an aperture of a container end wall, such as a beverage container, whereby pressurized gasses within the container force bias a tapered sealing panel into gas tight sealing engagement within a complementary tapered rim seal. An enclosing cover, providing contamination protection, is rotated open, uncovering a vent hole, exhausting pressurized gasses prior to the tapered sealing panel being opened, such as to provide a pour opening. Rotation of the cover actuates co-joined levers that transfer a force to automatically open or close the tapered sealing panel. A space located on the inside surface of the cover is first available to a user, containing indicia and promotional messages on initial opening of the container.

Description

FIELD OF THE INVENTION [0001] The present invention relates to an end member of a container, such as an aluminum beverage container, having an aperture defining a pour opening set in an end wall of a container. Such a container will be pressurize, caused by dissociating gasses released from the beverage product, resulting in high pressure gasses collecting within the container. Such gasses are required to be contained to protect the freshness of the product. BACKGROUND OF THE INVENTION [0002] A search of prior art reveals many patents issued that address the opening, venting and resealing of a container, such as an aluminum beverage can. [0003] Once the can is open, if all the contents are not consumed, any remaining beverage could be resealed, and remain fresh for later consumption. This would eliminate the present practice of disposing of the unconsumed contents, which is wasteful, and can be inconvenient or inappropriate. Numerous U.S. patents such as, U.S. Pat. Nos. 4,442,950. 4...
