Abstract: The present invention generally relates to a flexible tab used to open beer/beverage can ends and food can ends. The tab has a plurality of slots provided in about a middle part of the tab between a nose portion and a lift portion on opposing sides of the tab. The slots combine to form a fulcrum that extends generally transverse to an axis that passes along a length of the tab. The fulcrum allows the lift portion to pivot upwards and downwards in relation to the nose portion. The tab also has a paneled or beaded area adjacent to the slots at about the middle part of the tab. Tooling for the manufacture of the flexible tab is also provided. A method for manufacturing the flexible tab is additionally provided as well.

Abstract: An easy open can end has an improved structure for facilitating the opening operation of the tear panel, a method of further forming a can end to have the improved structure, and tooling for accomplishing the method. The further formation of the can end is particularly useful in easy-open can ends having enlarged tear panels.

Abstract: An easy open can end having shallow panel integrally formed in the tear away panel and a tab nose bead formed on the panel proximate the rivet, a method of further forming a can end to incorporate the aforedescribed features, and tooling for the further forming of the easy opening end.

Abstract: An easy open can end having an improved rivet structure integrally formed thereon for the attachment of a pull tab, a method of further forming a can end to incorporate the improved rivet, and tooling for accomplishing the method. The further formation of the can end includes the steps of bubble formation, first button formation, and final rivet formation.

Abstract: A sheet metal end closure for a container of pressurized products, which closure includes a substantially planar central panel, a countersink around the central panel, a chuckwall around the countersink and a seaming flange around the chuckwall. It further includes an annular downwardly stepped portion between the central panel and the countersink and a coined zone in the panel radius which connects the stepped portion to the countersink. The invention includes a method and apparatus for forming such a sheet metal closure wherein the panel radius between the central panel and the countersink is coined around at least a portion of the circumference of the central panel before the periphery of the central panel is reformed. In accordance with this invention, a major portion of the central panel is moved away from the countersink by depressing the outer peripheral portion of the central panel along with the countersink and chuckwall.

Abstract: An improved easy open can end having a retained tear strip extending diametrically partly across the can end defined by a score line, and a graspable pull tab adjacent and outside the open end of the score line. The pull tab is attached to the can end by means of a rivet, the can end around the base of the rivet being deformed so as to slightly tilt the rivet toward the finger end of the pull tab. Accordingly, initial lifting of the pull tab is fully directed to the initial fracture of the score line immediately in front of the rivet, thereby ensuring desirable venting action of internal pressure and allowing opening of the can end with less effort.
