ABSTRACT:
A tear open bottle cap formed of lightweight sheet metal having a circular top panel surrounded by a cylindrical skirt connected thereto by a radiused juncture portion. 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 diverge outwardly away from each other within the radiused juncture portion and continue part way about the periphery of the cap top panel in a circular path. The terminal portions of the score lines extend outwardly into the cap skirt at spaced positions opposite the pull member. An annular sealing gasket is disposed within said cap top so as to lie just radially inwardly of the circular scoring.
