Abstract

A closure cap for closing the opening of a bottle container. A neck of the bottle container includes a latching projection. The closure cap includes a latching arm attached to a ring (R), which circumferentially encircles the neck of the bottle container underneath the latching projection. The ring (R) includes a length store (L) and an undergripping projection. The length store allows the ring (R) to be flexed so that the diameter of the ring is large enough to pass over the latching projection. The undergripping projection is located on the upper side of the ring and sits against the latching projection when the ring (R) is in an unflexed position.
