ABSTRACT:
A closure cap, in particular for bottle-like containers, having an element assuring intactness, which is connected by tear strips with a cap portion and remains on the container after the closure has been opened for the first time by tearing the tear strips, characterized in that a separation seam separating the element assuring intactness from the cap portion has a first set of alternating segments disposed in zigzag fashion periodically about the circumference of the element insuring intactness and additionally has a second set of alternating segments similar to said first set and carried by the cap portion. The first and second sets of segments mesh with each other. Tear strips are carried by the cap jacket between the element insuring intactness and the cap portion. The first and second sets of segments mesh with one another and serve as a coupling means during closure. The segments of the separation seam may be embodied in a plurality of forms including an undulating form; a sawtooth-like form; in quadrilateral, square or rectangular form; a semitrapezoidal form; and a trapezoidal form.
