  • Bottle cap seal
    Patent number: 3933266
    Abstract: A bottle cap seal having a long skirt in which the seal is of the type which is used on sparkling wine and champagne bottles.The cap, formed by rolling a thin metal sheet on a punch and by gluing the superposed lateral edges, is formed with a depression in the gluing zone, adjacent its upper edge. The depression operates to prevent excessive penetration of one cap into the other during handling, with the result that the caps are easily adapted for use with automatic distribution and sealing machines.
