Abstract
The present invention relates to a fluid dispenser member comprising a body (1), a pusher (2) axially displaceable between a rest position and a depressed position, the pusher forming a fluid dispenser orifice (24), and a flexible part (3) connecting the body to the pusher. The part forms return spring means (35) urging the pusher towards the rest position. The part also forms the moving member (38) of an outlet valve. The part also comprises support means (33) engaged with the body, and anchor means (37) engaged with the pusher. The support means are surrounded by the anchor means. The part includes an elastically deformable portion (34) that extends between the support means and the anchor means. The elastically deformable portion (34) constitutes both the return spring means (35) and the outlet valve moving member (38).
