ABSTRACT:
An improved easy-open end closure has a generally C-shaped ancillary scoreline in the end panel closely adjacent a rivet which is positioned between a piercing portion of a tab to which it is attached and at least a portion of the rupturable ancillary scoreline. The peculiar shape of the scoreline, with its inwardly looped ends, facilitates movement of the handle portion of the tab away from the end panel by rendering the adjacent portion of the end panel more flexible and minimizes tear out of the flexing portion of the panel by substantially eliminating areas of stress concentration.
