Distribution unit e.g. pump fixing device for e.g. perfumery field, has shoulder forming gripping unit, and stop unit formed by lower end, where units define axial retention unit for locking hoop on ring in separated axial positions

摘要

The device has a fixing ring (1) with a fixation unit (12) in the shape of a continuous locking cord passing by forcibly fitting on a neck of a container. A covering hoop (2) is axially engaged from the top to the bottom around the ring and comprises a shoulder forming a gripping unit which cooperates with a stop unit formed of the hoop, where the stop unit is formed by the lower end of a skirt (11). The gripping unit and the stop unit define an axial retention unit for locking the hoop on the ring in distinct, separated axial positions.
