Реферат: ABSTRACT OF THE DISCLOSURE An improved easy open can end having a retained tear strip extending diametrically partly across the can end defined by a score line, and a graspable pull tab adjacent and outside the open end of the score line. The pull tab is attached to the can end by means of a rivet, the can end around the base of the rivet being deformed so as to slightly tilt the rivet toward the finger end of the pull tab. Accordingly, initial lifting of the pull tab is fully directed to the initial fracture of the score line immediately in front of the rivet, thereby ensuring desirable venting action of internal pressure and allowing opening of the can end with less effort.
