Abstract

A sheet metal pull tab for easy opening cans of the full panel pull-out type which has a special and coordinated configuration, shape and contour of pull-ring, keyhole-shaped slot, nose and nose-forming walls which serve readily without tab failure to rupture the score line formed in a can end for removal of an end panel defined by the score line. The new pull tab structure imparts unusual overall strength to the pull tab that enables the pull tab either to provide greater strength when formed from the same gauge sheet metal or to provide the same strength when formed from lighter gauge sheet metal as compared with similar prior sheet metal pull tabs having the same outer contour; and also to provide such a pull tab structure which reduces the amount of metal, disregarding gauge, that is required to form the strong pull tab structure.
