  • Bottle cap with gasket
    Patent number: 3958710
    Abstract: A bottle cap is disclosed having a pair of spaced score lines extending across the top of the cap and across a peripheral depending skirt to the edge. A sealing element is bonded to the surface of the inside of the cap. The bonded interface between the sealing element and the cap extends across portions of each of the score lines away from a downwardly depending tear-off flap. The bonded interface serves to prevent tearing of the score lines when the cap is removed. The sealing element is undamaged when the cap is removed so that the cap may be reused.
