ABSTRACT:
A tear-off convenience bottle cap formed of lightweight sheet metal having a circular top panel surrounded by a cylindrical skirt. An annular sealing gasket disposed within said cap at the juncture of the top and skirt. An integrally formed pull member extends away from the skirt edge with a score line commencing at either side of the pull member extending upwardly across the cap skirt. The score lines continue part way about the periphery of the cap top panel protected against exposure to the bottle contents by the annular sealing gasket and are then directed radially outwardly into the cap skirt opposite the pull member, thus minimizing the pull force required to dislodge the cap from the underlying bottle finish at the termination of the tearing action.
