Abstract: A fluid dispenser device comprising: at least one predosed reservoir (10) that is hermetically sealed and that contains a single dose of powder; an expulsion channel (20) that is terminated by a mouthpiece; and a reservoir opening system (30), each reservoir (10) including a closure layer (12) that is suitable for being pierced and/or torn by said opening system (30) so as to enable the powder that is contained in said reservoir (10) to be expelled through said expulsion channel (20), said reservoir opening system (30) comprising at least two piercer elements (31) that are actuated so as to create at least two distinct openings (25, 26) in said closure layer (12), forming at least one inlet passage (25) for the flow of gas, in particular air, and at least one outlet passage (26) for the powder entrained by said flow of gas, and said device including an inhalation trigger system (50) that creates a flow of gas in said expulsion channel (20) only when a user inhales at or above a predetermined inhalation thresh

Abstract: A fluid dispenser valve for mounting on a neck (2) of a reservoir (1) containing fluid, said valve comprising a valve body (10) including a metering chamber (15), and a valve member (20) that is movable in said metering chamber (15) between a rest position and a dispensing position, said metering chamber (15) including an upper gasket (30) and a lower gasket (40) that co-operate in leaktight manner with said valve member (20), said valve including a neck gasket (50) that co-operates in leaktight manner with said valve body (10) and with said receptacle neck (2), said neck gasket (50) and/or said upper gasket (30) and/or said lower gasket (40) being welded or adhesively bonded on the valve body (10).

Abstract: A dispenser head for mounting on a fluid dispenser, said dispenser head comprising a body (1) provided with a dispenser orifice (10), said head being provided with a cap (2) that is displaceable between a closed position, in which it covers said dispenser orifice (10), and an open position, in which it does not cover said dispenser orifice, said cap (2) being connected in permanent manner to said body (1), regardless of the position of said cap.

Abstract: An inhaler (1) for dispensing accurate and reproducible doses of powder. The inhaler includes an expulsion channel (2) opening out in an outlet orifice (3), and is characterized by a combination of or: a pre-dosing device (100) having the powder in individual reservoirs (101), each reservoir (101) containing one dose of powder, and; a transfer device (200) for transferring a dose of powder in full into the expulsion channel (2) on each actuation of the inhaler. The inhaler also includes an air flow source (300) having a pump (301) triggerable by the user the air flow source (300) sending a flow of air into the expulsion channel (2) towards the outlet orifice (3) to expel the dose of powder.

Abstract: A device for dispensing a fluid and operating without air intake, the device comprising a pump (1) mounted on a receptacle (3) containing the fluid, and a pushbutton (10) for actuating said pump, said pushbutton (10) including a fluid dispensing orifice (17), a substance having bacteriostatic activity on said fluid when it comes into contact with said substance being disposed in said dispenser device, the device being characterized in that said pushbutton (10) includes a nozzle (11) defining an expulsion channel (13) that is narrow and of small volume between the pump (1) and the dispensing orifice (17), said substance having bacteriostatic activity being disposed solely in said pushbutton (10) on or in the vicinity of said nozzle (11) such that said substance having bacteriostatic activity is of maximum effectiveness because of the small dead volume in the pushbutton.
