1. The cap made of formed plastic is designed for closing containers with necks. It consists of the top, the cylindrical cover equipped with at least one helical rib on the inside, and the anti-tempering ring. The latter is detachable along the incision line in the plane perpendicular to the symmetry axis of the cap. The anti-tempering ring has the form of a ring-shaped band, which constitutes a bottom extension of the cylindrical cover. At the bottom edge, the ring-shaped band has a tape, which is turned inside and contains at least one gap. The tape is deflected upwards and rests against the ring on the container neck, when the cap is closed. The ring-shaped band contains at least one formed zone of lower strength, extending parallel to the symmetry axis of the cap, along the height of the ring-shaped band, between its bottom edge and the transversal plane of the incision. The band also contains a local thickening, protruding on the edge side of the internal surface of the ring-shaped band. The thickening is on both sides of the transversal plane of the incision and one of its edges adheres to the ring plane of the cap, which goes through the zone of lower strength. Unique characteristics: The angular width of the local thickening (11) of the ring-shaped band (5) corresponds to the angle between two successive gaps (7) in the tape (6) turned inside. |
