ABSTRACT:
An improved easy open end closure, characterized by the provision of improved pull tab positioning means for maintaining the pull tab in a desired orientation relative to the flap-defining score line, regardless of doming of the end panel. The finger ring portion of the tab is nested within a recess formed in the end panel. A protrusion, formed interior to this recess, abuts the interior periphery of the finger ring, serving as an anti-rotation abutment. The tab rivet panel is formed at an angle to the plane of the tab, inclining 4.degree.-6.degree. away from the end panel center, whereby a panelward bias is imparted to the finger ring portion of the tab by the tab attachment rivet. This bias serves to retain the finger ring within the recess.
