Abstract: A treatment method for treating the surface of a fluid dispenser device, said method being characterized in that it comprises a step of using chemical grafting to form a thin film on at least one support surface of at least one portion of said device that is in contact with the fluid while said device is being actuated, said thin film having non-stick properties relative to said fluid.

Abstract: A fluid dispenser device comprising: a body (100) that is provided with a dispenser orifice (110); a reservoir (1) containing fluid and a propellant gas; and a metering valve (20) that is assembled on said reservoir (1); said reservoir (1) being movable in said body (100) so as to actuate the metering valve (20) and dispense a dose of fluid through said dispenser orifice (110), said metering valve (20) including a valve member (30) that slides in said metering valve (20) during actuation; said device further comprising at least one sealing element (40, 41, 42) so as to form a leaktight seal, at least one sealing element (40, 41, 42) of said device comprising COC elastomer.

Abstract: A treatment method for treating an elastomer surface of a fluid dispenser device, the method including the step of using chemical grafting to form a thin film on at least one support surface of at least one elastomer surface of the dispenser device, the thin film avoiding the elastomer surfaces sticking during the manufacturing and assembly stages.

Abstract: A treatment method for treating the surface of a fluid dispenser device, said method comprising the step of using chemical grafting to form a thin film on at least one support surface of at least one component part that is in contact with said fluid, said thin film preventing interactions between said fluid and said component part.

Abstract: A fluid dispenser head including a fluid dispenser member; a dispenser endpiece that is connected to a nozzle via a duct; a pusher that is manually and axially movable down and up so as to move the dispenser endpiece, in such a manner as to dispense fluid; and a rotary control hoop for moving the pusher axially between a storage position and an actuatable position. The head further includes axial guide for guiding the pusher axially without turning about its own axis; and rotary cam that is turned by the control hoop, the pusher being in engagement with the cam so as to urge the pusher in axial movement, without any turning component.

Abstract: A fluid dispenser comprising: a fluid reservoir including a neck defining an opening; and a dispenser member, such as a pump or a valve, including a body that is held in stationary manner in the opening of the reservoir, defining an annular gap between the neck and the body; a source of radiation being disposed in the annular gap.

Abstract: A dose counter, the counter having a base body, with a rotary counter element assembled in the base body on a pin forming the axis of rotation. The rotary counter element co-operating with an actuator member adapted to cause the rotary counter element to turn each time the actuator member is actuated. The actuator member including a fastener for fastening to the base body (460) and arranged on a first side of the pin, and a substantially rigid support portion arranged on a second side of said pin. The support portion supporting an actuator element so that, on each actuation, the actuator element is moved in translation. The support portion is connected to the fastener via an elastically-deformable portion that surrounds the pin. The support portion is extended towards the pin by a substantially-rectilinear flexible branch that supports a lug adapted to co-operate with the counter element on each actuation.

Abstract: A fluid dispenser device including: a body (1) incorporating a dispenser orifice (5); a reservoir (10) containing the fluid; and a dispenser member (15), such as a metering valve or pump, for selectively dispensing the fluid contained in the reservoir (10), the device also including a dose indicator having an electronic display the display including a permanent display member (21) that does not require any energy in order to keep the display unchanged, and that requires only a small amount of energy in order to change the display.

Abstract: An inhaler comprising: a body; at least one cover element that is movable between a closed position and an open position; individual reservoirs formed on a reservoir substrate; movable support means that receive said reservoir substrate and that are displaceable between a non-dispensing position and a dispensing position; and an indicator device for indicating doses that have been dispensed or that remain to be dispensed, said indicator device comprising: a rotary indicator element that supports indicator means, such as numbers, colors, and/or symbols; and an actuator that co-operates with said movable support means so as to cause said rotary indicator element to turn when said movable support means return from the dispensing position to the non-dispensing position.

Abstract: A treatment method for treating the surface of a fluid dispenser device, said method comprising the step of using chemical grafting to form a thin film on at least one support surface of at least one portion of said device that is in contact with said fluid, said thin film having bactericidal and/or bacteriostatic properties.

Abstract: A fluid dispenser including, a fluid reservoir with a neck externally threaded and that internally defines an opening that communicates with the inside of the reservoir, the neck forming at least one helical thread; and a dispenser head that is mounted on the neck by a fastener member in engagement both with the threaded neck and with the dispenser member. The fastener member includes a ring, the ring forming: a reception mechanism for receiving the dispenser member; an annular ledge; and a skirt that is in engagement with the threaded neck. The ring includes a rupture mechanism between the ledge and the skirt so as to separate the ledge from the skirt by turning the ring on the threaded neck, in such a manner as to remove the dispenser member from the reservoir.

Abstract: A fluid dispenser device having a dispenser member, such as a pump or a valve, that is mounted on a fluid reservoir and that is actuated by a dispenser head that includes a spray orifice. The device further having a visual indicator that is movable between an indicating position and a non-indicating position, the visual indicator being moved into their non-indicating position at the start of each actuation of the dispenser member, and being moved from the non-indicating position towards the indicating position by the fluid, while it is being dispensed.

Abstract: A fluid dispenser including a fluid reservoir including a neck with a constricted opening that communicates with an inside volume; and a dispenser member including a fluid inlet that is provided with a dip tube, the dip tube provided with a substantially-plane flexible sheet having shape memory. The sheet presents a transverse dimension, in the direction that is perpendicular to the dip tube, that is greater than the dimension of the constricted opening, such that the sheet must be caused to take up a deformed configuration in order to pass through the neck, and must then relax into a substantially-plane rest configuration inside the inside volume. The sheet presents a bottom edge having a portion that, in the rest configuration, penetrates into the constricted opening to initiate the deformation of the sheet, so as to bring it subsequently into its deformed configuration.
