Dispensing element e.g. pump, for use with fluid product dispenser in e.g. cosmetic field, has valve seal defining truncated contact surface, and actuation assembly in sealed contact with surface in extended rest position of assembly

摘要

The element has a fixed pump body (1) defining a fluid product inlet (11) equipped with an inlet valve (12), and a stop element (21) secured to the fixed body and provided with a valve seal (3). An actuation assembly (4) is moved axially back and forth between an extended rest position and an inserted actuation position. The actuation assembly is stressed by a return spring (7) against the valve seal of the stop element in the rest position. The valve seal defines a truncated contact surface (33), and the assembly is in sealed contact with the contact surface in the rest position.
