摘要

The invention relates to a cover member (1) which is intended to be mounted to a fixing ring (2), said cover member and ring together forming a fixing device for fixing a dispensing system (3), such as a pump or a valve, to the neck of a container (40). The cover member has an essentially-cylindrical configuration and comprises an outer wall (14) and an inner wall (15) which is intended to come into tight contact around the ring (2), said inner wall forming a network of hollow grooves (16, 17) from a base zone (151), which extend in at least two different directions.
