ABSTRACT:
An easy open can cap has an elongated tear strip defined by a main score and a ring pull tab attached to the tear strip by a rivet. A bending score is provided on the tear strip near the rivet, the bending score extending perpendicular to a longitudinal extending center line of the tear strip so that when the ring pull tab is initially lifted, the tear strip bends at the bending score to thereby reduce the applied force necessary for initiating opening of the tear strip. The main score has a starting end portion extending partially around the area of said rivet and a terminating end portion at the opposite end of the tear strip, the main score having a transitional portion between the starting end portion and the terminating end portion with the transitional portion having a thinner score residual than that of the starting end portion.
