Abstract
An easy open end employs an enlarged 'moustache' score, in which the apex of the outward curves of the score lie outside of the plane of the sides of the pull tab to effectuate a rolling of the metal ribbon between the rivet and the peripheral weakened area, so as to avoid lateral forces which tend to tear the metal along the ribbon.
