Abstract: A dispenser member such as a pump or a valve, comprising:

Abstract: A fluid dispenser device such as a pump or a valve designed to be fitted to a neck of a receptacle, said device comprising: a body in which a piston can be caused to slide by depressing a pusher; a fixing member for fixing the body to the receptacle neck; and a dip tube for bringing the fluid from the receptacle to the body, the dip tube having a free end situated in the vicinity of the bottom of the receptacle and a fixed end held by connection means; wherein the connection means are formed by the fixing member.

Abstract: A hand-operated pump for fluid distribution comprising a pump body defining a pump chamber, a hollow control rod traveling in the pump body between a rest position and a depressed, lower position, a free floating piston assembled in a sliding manner on the control rod, the piston and the rod serving to define an outlet valve, characterized in that the outlet valve exhibits a cylindrical tight sealing contact adapted to open by sliding the piston towards the top on the rod at a determined height and the rod includes a surface engaged by the piston and widening in a vertical direction towards the top.

Abstract: A fluid-dispensing member is designed to be mounted on the neck of a container. The dispensing member includes: a body defining a chamber that slidably receives a piston; a fixing member designed to co-operate with the neck and extending around the body; and a delivery channel connecting the chamber to a stationary dispensing orifice. The delivery channel is formed between the body and the fixing member. The fixing member is suitable for co-operating with an inside wall of the neck so as to fix the dispensing member in the neck.

Abstract: A fixing device for fixing a dispensing member to the neck of a receptacle, said fixing device comprising:

Abstract: A fluid dispenser device comprising: a fluid pump (1) comprising: a pump body (10) provided with an inlet valve member (12); an actuating rod (2) mounted to move axially in the body (10); and a free piston (3) mounted to slide in leaktight manner in the body (10), the piston (3) being mounted to move over the actuating rod (2) to form an outlet valve member (332) therewith; and an air pump comprising an air chamber (54) provided with an inlet valve member (515), with an outlet valve member (331), and with a piston (48) for compressing the air in the chamber; the fluid dispenser device being characterized in that the outlet valve (332) of the fluid pump and the outlet valve (331) of the air pump open out into a common duct (23).

Abstract: A fluid-dispensing member comprising: a body defining a chamber; an actuating rod provided with a pusher; a piston mounted on the actuating rod to slide in leaktight manner in the chamber; an inlet valve; and an outlet valve; wherein the outlet valve comprises a differential piston that can be moved under the action of the pressure exerted on the fluid by the piston against the action of a spring which abuts at one end against the differential piston, and at its other end against the pusher.
