Abstract of the Disclosure: An integral tongue is lanced from a steel can top except along a transverse bend line scored on the undersurface of the tongue adjacent to the can top. An arcuate nose portion of a pull tab is riveted to a first portion of the tongue. Opposing shoulders on the tab overlie portions of the can top adjacent to the tongue. A ring or lever portion of the tab is lifted and pivoted on the shoulders, thereby bending the first portion of the tongue under a ribbed second portion. The pull tab is then pivoted in the opposite direction, thereby displacing the entire tongue outwardly relative to the can top along the bend line.
