  • Blank for a bottle cap
    Patent number: 4256233
    Abstract: A blank for forming a bottle cap is disclosed, the completed bottle cap having a tear tab cooperating with score lines extending across the top of the cap for manual removal of the cap from a bottle. Two score lines are provided which extend from the tear tab to the opposite side of the blank, the score lines being asymmetrical to facilitate the formation of a tear-off tab. The described arrangements of score lines serve to obtain an easy removal of the cap from a bottle after the tearing operation.

  • Bottle caps
    Patent number: 3963140
    Abstract: A bottle cap is disclosed having a tear tab cooperating with score lines extending across the top of the cap for manually removal of the cap from a bottle. The score lines are located slightly spaced from the peripheral edge of the top of the cap and arranged at least partly around the periphery of the cap. This arrangement of the score lines serves to obtain an easily removal of the cap from the bottle after the tearing operation and is moreover in combination with the sealing element effectively preventing any risk for corrosion along the score lines.

  • 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.
