Abstract
A fluid product dispenser having a vessel and provided with a neck forming at least one helical thread, and a dispensing head mounted on the neck of the vessel, the head having a dispensing member and a fastening member engaging both with the threaded neck and the dispensing member The fastening member has a deformable and malleable skirt intended to engage with the threaded neck, and a rigid collar engaged around the skirt to push the skirt radially against the threaded neck in such a way as to deform the skirt against the thread so as to create a thread imprint in the skirt. The helical thread has an intermediate portion that has, on at least some of its length, a cross-section that decreases in the unscrewing direction and increases in the screwing direction, such that the unscrewing torque decreases and the rescrewing torque increases.
