  • Closure cap of plastic material
    Patent number: 4664279
    Abstract: The tear-off guarantee strip (6) of the closure cap (1) has a peripheral detent edge portion (9) whose inside diameter is smaller than the outside diameter of a peripheral projection (8) on the mouth (3) of a container. In addition to the detent edge portion (9), provided on the inside (7) of the guarantee strip are at least one holding projection (10) and a bead (26), which both strengthen the effect of the detent edge portion (9). The combination of detent edge portion, holding projections and bead gives optimum results in regard to the function of the guarantee strip and the possibility of removing the closure cap from molding tools which open in an axial direction.
