ABSTRACT:
An improved easy-open end closure pull tab comprising a double folded rivet panel having a lower portion which is carried beyond the outer periphery of the tab ring to form a nose. The panel fold functions as a spring to bias the tab away from the end panel of an end closure after assembly and raises the tab above the end panel so that the tab is springy which increases its abuse resistance. The double folded rivet panel construction allows machining the tab from thin sheet stock.
