A fluid dispenser member comprising a dispenser wall () defining an outside surface () and an inside surface (), said wall () having a dispenser orifice () passing therethrough, connecting the inside surface to the outside surface, the inside surface () forming a sealing slide-cylinder () for a piston () that is suitable for being displaced, from a rest position, along an axis X in said cylinder and with leaktight contact, so as to open an outlet valve (), said piston () forming a portion of a fluid chamber () in which fluid is selectively put under pressure and flows through the open outlet valve towards the dispenser orifice, the piston forming a closure wall () that is suitable for closing the dispenser orifice () in the rest position, the closure wall () being positioned, in the rest position, over the dispenser orifice () beside its inside surface (), the closure wall () coming into leaktight contact with the inside surface (),

Fluid dispenser member

A stopper member (C) for mounting on an opening () of a fluid reservoir (P), said member being characterized in that it comprises:

Stopper member, a fluid dispenser comprising such a member, and a method of manufacturing such dispenser

Fluid product dispenser

A fluid pump having a pusher with a push wall defining a push outside surface and an inside surface; and a peripheral skirt which extends from the inside surface of the push wall. A pump chamber is provided with an inlet valve and with an outlet valve, a dispensing orifice via which the fluid is dispensed, a main piston, and a differential piston that is mounted to move in the pump chamber in response to variation in the pressure. The differential piston is mounted to move away from the push wall when the pressure increases in the pump chamber; the pusher and the differential piston being mounted to move along an actuating axis that extends substantially perpendicularly to the push wall. The differential piston is formed integrally with an inlet valve moving member that co-operates with an inlet valve seat.

A fluid product dispenser having a reservoir of fluid product defining a moveable actuating wall, a distribution orifice, and a spring structured to act on the actuating wall to produce a state of maximum volume of the reservoir. The spring co-operates with an arming element structured to cause the spring from an initial state in which the spring does not bias the actuating wall to a state in which the spring biases the actuating wall.

A fluid dispenser () for dispensing a fluid in liquid or in powder form, the dispenser including a reservoir () serving to contain fluid, and a dispensing orifice () via which the fluid is dispensed. The reservoir () having an actuating wall () and a backing wall (), the walls be adapted to be brought towards each other by elastic deformation to reduce the volume of the reservoir, and thus to deliver fluid through the dispensing orifice. The dispenser further having a one-piece body () and at least one flexible sealing film (), the actuating wall and the backing wall being formed by the one-piece body, wherein the actuating wall and the backing wall are angularly positioned relative to each by forming an angle that decreases when they are brought towards each other.
