ABSTRACT:
An improved tab opener and retained-tab easy-open structure and end closure assembly method are disclosed. The tab opener is fabricated from flat-rolled sheet metal to present a rounded edge periphery. In preparing an end closure for assembly on a can body, the tab opener is secured to the end closure such that the raw edge sheet metal of the rounded periphery is disposed outwardly in relation to the can body. The raw edge metal, scorelines, and other portions of the end closure needing repair can be repaired simultaneously after securing the tab opener to the end closure.
