Abstract
A closure cap that is connected captively with the neck of a container. To this end, a retaining ring is used to engage beneath a bead on the container mouth when the cap is in position on the container mouth. The cap wall is firmly connected with this retaining ring by the tether. The retaining ring at the same time serves as an anti-tamper security for the closure. In its original condition, the tether runs between the cap wall and the retaining ring along the circumference of the closure cap and is connected by nominal rupture bridge pieces not only with the retaining ring but also with the lower edge of the cap wall. In order to avoid the risk of destruction of these nominal rupture bridge pieces during fitting of the closure cap, and at the same time ensure that the retaining ring holds firmly to the container mouth with the closure cap in position on the container mouth, the retaining ring is equipped with a plurality of tongues protruding radially inwards from its inner surface, the tongues being aligned upwards towards the cap base and engaging beneath the bead on the container mouth when the closure cap is in position on the container mouth.
