Abstract:
A fluid dispenser comprising: a fluid reservoir (10) serving to contain fluid; and a dispenser head (2) mounted on the reservoir (10) to take fluid from the reservoir, said head (2) defining a dispensing chamber (26) communicating with the reservoir via an inlet valve (25, 215) and communicating with the outside at a dispensing orifice via an outlet valve (237, 222); said dispenser being characterized in that the chamber (26) comprises at least one elastically deformable actuating wall (231) that is depressed in order to generate a pressure inside the chamber that is high enough to close the inlet valve and to open the outlet valve.
Abstract:
The present invention relates to a device for distribution of fluid products of the type which has container (1) in which product (P) to be distributed is held and on which a distribution device is mounted, which is engaged in opening (2) of container (1) by the intermediary of bushing (3) and a sleeve. The invention consists of the fact that bushing (3) has cylindrical skirt (31) and at least two deformable tabs (33) arranged in the extension of cylindrical skirt (31) defining a receiving space for the sleeve in which pump body (4) is mounted, at least free ends (33a) of tabs (33), before introduction of pump body (4), projecting towards the interior of said space in order to allow passage through opening (2), bushing (3) having radial projection (32) in such a way that, when radial projection (32) rests on the exterior edge of opening (2), tabs (33) project inside of container (1) at most up to zone of connection (a) with cylindrical skirt (31) and are separated by the sleeve in such a way as to lock bushing (3) in the opening.
Abstract:
A filling method for filling a reservoir (10) of variable working volume with a fluid, the method being characterized in that the reservoir (10) is firstly emptied of any content, such that its working volume is substantially zero, and the fluid is then injected into the reservoir, thereby increasing the working volume of the reservoir (10).
Abstract:
A dispenser head for mounting on an actuator rod of a fluid dispenser member. The actuator rod is displaceable up and down along an axis. The dispenser head includes a bearing surface for displacing the dispenser head and for actuating the fluid dispenser member. The head further includes a dispenser endpiece that internally defines an endpiece channel that opens out to the outside at a dispenser orifice. The endpiece presents an elongated configuration with a connection end connected to the remainder of the head and a free end. The dispenser orifice is situated in the proximity of the free end. The dispenser orifice is provided with internal closure member that is suitable for selectively closing the dispenser orifice from the inside.
Abstract:
A fluid dispenser device comprising: a reservoir (R) of variable working volume comprising a sealing slide-cylinder (100) and a follower piston (2) that is in sliding sealing contact in said cylinder; dispenser means (3) that are suitable for putting the fluid stored in the reservoir under pressure in such a manner as to drive a fraction of the fluid through a dispenser orifice (37), and under suction in such a manner as to move the follower piston in the direction that decreases the working volume of the reservoir; and non-return means that are suitable for preventing any substantial movement of the follower piston in the direction that increases the working volume of the reservoir; in which device the non-return means include at least one chamber (C) of variable volume that is filled with fluid from the reservoir during the suction stage.
