Abstract: A fluid dispenser having a receptacle with a neck (10); a dispensing member (2); and a fixing member (3; 2) for fixing the dispensing member (2) to the neck (10) of the receptacle (1). The fixing member cooperates with the inside wall of the neck, which is provided with a notch (12) that extends over a portion of the periphery of the neck, and the fixing member provided with snap-fastening means (32; 22) and with a skirt (30, 20) that engages in the neck of the receptacle. The snap-fastening means has an outside radial projection (32; 22) received in the notch in the inside wall of the neck. The snap-fastening means further has a locking ring (4; 20; 61) engaged in the skirt to the level of the notch (12) in the inside wall of the neck.

Abstract: The invention concerns a fixing device for a fluid product dispenser adapted for mounting on a container or reservoir which has a neck. A dispensing member is mounted on the reservoir neck. The neck has an outer peripheral thickness defining, with the rest of the neck, a lower shoulder. The fixing device comprises a fixing ring to fix the dispensing member on the neck. The fixing ring comprises a peripheral skirt extending up to beneath the shoulder. The skirt is provided with flaps, the ends of which point inwards and upwards and are urged to stop in contact against the shoulder thereby providing a catching mechanism for the fixing ring on the reservoir neck.

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 packaging assembly, including a fluid dispenser defining substantially parallel opposite side edges, and a housing having two substantially parallel opposite sides. Each side defines an inside wall, with the two inside walls facing each other, and each inside wall is provided with a respective longitudinal groove which extends over at least a portion of the length of the side. The two resulting grooves are parallel, and at least a portion of each of the opposite side edges of the dispenser are slidably engaged in the corresponding one of the grooves in the housing, so as to enable the dispenser to be slidably extracted from the housing.

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 dispenser device has a fluid reservoir (10) and a dispensing member (20), such as a pump, actuated by an actuating rod (5) that is connected to a dispenser head (30) to dispense fluid selectively. The dispensing member is fixed to the reservoir by a fixing element (40), the dispenser device being provided with an air vent (50) situated outside the reservoir and outside the fixing element, an air filter element (60, 75) being disposed in the vicinity of the air vent, outside the fixing element, and the filter element being held on or in the vicinity of the air vent by an outer member (70) fixed to the fixing element and/or to the reservoir. The outer member has a fixing portion (71) which is fixed to the fixing element of the dispenser device, and a flexible membrane portion connected in leaktight manner to the actuating rod and/or to a piece (35) of the dispenser head.

Abstract: A fluid dispenser having a reservoir forming a bottom, side walls, and a neck; and a dispensing member, such as a pump or a valve mounted on the neck. The dispensing member is provided with a tube extending inside the reservoir to the point of being in contact with the bottom via its free bottom end. At least over a portion of the tube's length, the tube has a deformation zone that is deformed by the free end of the tube pressing against the bottom.

Abstract: A dispenser device is provided for dispensing a fluid substance in spray form. The dispenser device comprises a reservoir containing the fluid to be dispensed and a spray orifice. The reservoir includes at least one actuating wall that can be deformed by applying a pressing force.

Abstract: A reservoir (10) containing a fluid to be dispensed, and provided with a closure and/or filling device for closing and/or filling said reservoir, said device comprising at least one closure element (20, 120, 220) acting as a leaktight closure stopper when at rest,-said at least one closure element (20, 120, 220) comprising: an annular portion (21, 121, 221) whose outside diameter corresponds substantially to the inside diameter of the reservoir (10), said annular portion (21, 121, 221) being inserted in leaktight manner in said reservoir; and a central portion (22, 122, 222) having an end wall (23, 123, 223) which closes off said reservoir (10) in leaktight manner when in the rest position; said reservoir being characterized in that said end wall (23, 123, 223) is provided with at least one slit (24, 124, 224) suitable for opening under the effect of at least a predetermined minimum pressure.

Abstract: A pre-compression pump for dispensing metered quantities of fluid, said pump including a piston (1) secured to or integral with an actuating rod (2) and slidably-received in a pump body (3) including a pump chamber (10) defined between an inlet valve (11) and an outlet valve (12), said pre-compression pump being characterized in that, when the pump is actuated, said outlet valve (12) is urged towards its closed position by the pressure of the fluid contained in the pump chamber (10), and in that, at the end of the actuating stroke of the pump, a lever element (30) moves said outlet valve (12) towards its open position to enable the fluid contained in the pump chamber (10) to be expelled.
