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.
Abstract:

Abstract:
The invention relates to a fluid product distribution body (1), comprising a fluid product distribution chamber (10) with a variable volume defined with an inlet valve (15, 115), by means of which the chamber (10) communicates with the reservoir (20), said valve comprising a seat (115) and a moving body (15), a piston (135) which may be displaced to vary the volume of the chamber (10), said piston (135) being held in the rest position by means of a return spring (131) and an outlet valve (131, 125), by means of which the fluid product escapes from the chamber (10), under pressure, to flow towards a distribution opening (127). Said valve comprises a valve seat (125) and a moving valve body (131) which may be displaced with a sealing effect when not in contact with said seat, the return spring means and the mobile valve body being formed by one and the same element (131) comprising a wall (130) in sealing contact with the seat (125), the seat (125) having an annular embodiment. The invention is characterised in that the element (131) runs in a sealing manner within the seat.
Abstract:
A fluid dispenser comprising a first fluid dispenser member (1) associated with a first fluid reservoir (15), said first member comprising a first actuating rod (11) mounted to move along a first rod axis between a rest position and an actuated position, and a second fluid dispenser member (2) associated with a second fluid reservoir (25), said second member comprising a second actuating rod (21) mounted to move along a second rod axis between a rest position and an actuated position, the first rod (11) having a free end (111) pointing in a first direction and a second rod (21) having a second free end (211) pointing in a second direction, the two members being disposed one relative to the other with the first and second rod axes extending parallel and with the first direction being opposite to the second direction, so that one dispenser member is disposed upside down relative to the other dispenser member, said fluid dispenser being characterized in that at least one of the reservoirs is an “airless” reservoir, with its volume decreasing as fluid is extracted therefrom.
Abstract:
A pump of type comprising a moving member mounted to move relative to a support, the moving member having a central duct into which the substance to be dispensed penetrates via at least one opening, the support co-operating with the moving member to define a variable volume pump chamber around said central duct, the pump also having a diaphragm having a central portion in which said central duct is inserted, the diaphragm being organized in such a manner as to isolate the pump chamber from the opening(s) of the central duct when the volume of the pump chamber increases and the substance is sucked into it. At least one of the central duct and the central portion of the diaphragm includes an annular bulge that is suitable, when the volume of the pump chamber increases, for bearing in leakproof manner on the other of the central portion and the central duct of the diaphragm, so as to isolate the pump chamber from the opening(s) of the central duct.
Abstract:
This invention has as its subject a dispensing device for fluid-like products, composed of a container having a cylindrical drum, of which one end is provided with a movable base and the other end includes a neck which is capped by a distributor assembly including a pump with axial intake which is fitted onto a plunger sleeve. The lower face of the sleeve penetrates into the neck of the container during the fixing of the distributor assembly in the neck of the container, coming into position in sliding sealing engagement with a bearing surface of the neck.
Abstract:
A method for packaging a fluid product dispenser, where the said dispenser includes a reservoir (1) of constant effective volume filled with a fluid product (10), and a dispensing device (3) that includes a dip tube (2) which is intended to extract the fluid product (10) contained in the reservoir on operation of the dispensing device (3), the reservoir (1) and the dip tube (2) being made from a material or materials that are substantially or perfectly transparent, where the said dip tube initially contains air (A), and the dip tube (2) is connected to the dispensing device and has one free end extending to the bottom of the reservoir,the method being characterized in that the air (A) is extracted from the dip tube (2) and is replaced by the fluid product.
Abstract:
A fluid dispenser comprising: a fluid reservoir (1) having a neck (11) defining an opening (10) and an axis X, the neck (11) projecting axially from a shoulder (13); and a dispenser unit (D) comprising a dispenser member (4), such as a pump or a valve, and a fastener system (2, 31) for fastening the dispenser member (4) on the neck (11) of the reservoir (1), the fastener system comprising a fastener ring (2) that is engaged with the neck (11) and a blocking hoop (31) that is engaged axially around the ring (2) for blocking the ring on the neck in the final assembled position; disassembly means (14, 34) for axially moving the hoop (31) relative to the ring (2), from the final assembled position to a disassembled position in which the hoop does not block the ring on the neck, such that the unit (D) can be removed from the neck (11), the disassembly means comprising two elements (14, 34) capable of turning mutually relative to each other about the axis X, the dispenser being characterized in that one element (14) of the disassembly means is secured to the reservoir, while an other element (34) is secured to the dispenser unit (D).
