Anti-unscrewing system between the dispenser head and the container of a dispenser device of a liquid, e.g. trigger operated

摘要

A connection system between a dispenser head (10) of a liquid and a container (2) of the liquid, comprising a base area (15a) of a frame (12) and a flange (50) screwed tight onto the neck of the container. The free rotation of the frame is prevented by a resistant torque, but the base area (15a) of the frame is made in such a way as to allow the accidental rotation of the head without unscrewing the flange.
