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).

Abstract: A dispenser head (1) for assembly on two parallel, hollow actuator rods, said head being made as a single piece of plastics material and comprising: two parallel coupling sleeves (11, 12) for engaging with respective ones of the actuator rods, the sleeves defining respective inlet ducts (110, 120); a dispenser endpiece (13) defining at least one outlet duct discharging into at least one dispenser orifice (1310, 1320); and a cross member (10) linking the sleeves to the endpiece, the cross member defining at least one connection duct (101, 102) linking the inlet ducts (110, 120) to the outlet duct(s) (1310, 1320), said at least one connection duct extending transversally both relative to the sleeves and relative to the outlet duct(s), said at least one connection duct (101, 102) including an access opening (1010, 1020) closed by a closure element (14, 15),the dispenser head being characterized in that the closure element (14, 15) is made integrally with the remainder (10, 11, 12, 13) of the head.

Abstract: A method of assembling a fluid dispenser comprising: a dispenser member (2), such as a pump, the member including an inlet tube (22; 61) in which there extends an inlet for admitting fluid into the dispenser member; a reservoir (10) for containing fluid, said reservoir comprising a cylinder (11; 11?) and a follower-piston (14) that is slidably mounted in said cylinder; and an annular dish (32; 32?) presenting an outer periphery (33) that is secured to the cylinder (11; 11?), and an inner periphery (321) defining an opening (20) of section that is small relative to the cylinder, the working volume of the reservoir (10) being defined between the dish (32; 32?) and the follower-piston (14) over a height of the cylinder, the method including the successive steps of: filling the reservoir (10) with fluid; and engaging the tube (22) in leaktight manner in the opening.

Abstract: A fluid dispenser having a substantially rigid shell (1) provided with an opening (14), a flexible pouch (23) fixed to a pouch support (2) forming a fixing bushing (22) defining an outlet passageway (24) for the fluid, and a dispensing member (3) such as a pump for extracting the fluid from the flexible pouch through the outlet passageway of the pouch support; and wherein the fixing bushing (22) of the flexible support (2) is fixed in the opening (14) of the shell (1).

Abstract: The invention concerns a fluid product dispenser comprising a gas reservoir (10), a fluid product reservoir (20), a dispensing head comprising at least one dispensing orifice (30). The gas reservoir and the fluid product reservoir are connected to the head so that their contents can communicate with said at least one dispensing orifice. The dispenser comprises a movable actuation wall (14; 24) to simultaneously generate a pressure state in the gas and fluid product reservoirs and thus force the fluid product and the gas through the said at least one dispensing orifice.

Abstract: A support (1) for a flexible pouch for a fluid dispenser, said support comprising an appendage (11) to which the flexible pouch is fixed via its opening, and a socket (12) on which a dispensing member such as a pump is mounted, said support defining a passageway (13) causing the dispensing member to communicate with the flexible pouch so as to enable fluid contained in the pouch to be extracted by the dispensing member, said support being characterized in that said support (1) is provided with at least one tube (2) defining an internal duct (20) open at both ends of the tube, said tube (2) being fixed to the support (1) so that it has a free end (21) extending inside the flexible pouch, while its “top” other end (22) is fixed to the support eccentrically relative to the passageway (13) so that it causes the internal duct (20) to communicate with said passageway (13).

Abstract: A fluid dispenser comprising: a flexible pouch (3) containing said fluid and provided with an opening (31); a dispensing member (5) such as a pump for drawing off fluid contained in the flexible pouch through said opening (31); and a shell (11, 12) surrounding said pouch (3) and provided with an opening (13) that coincides with the opening (31) of the flexible pouch; the shell being made in two portions (11, 12) assembled together along a connection line (14) passing through the opening (13) in the shell so that each shell portion forms a portion of the opening in the shell; said dispenser being characterized in that at least one shell portion (11, 12) is provided with a window (115, 125), through which the flexible pouch is visible.
