The method includes fixing the outlet valve element in the piston; inserting the piston and the outlet valve element into the sleeve; inserting from the top the spring and the inlet valve element into said sleeve; and inserting from the top the sleeve into the pump body.

Method for assembling a high-pressure precompression pump

A device for dispensing a fluid product, having a body with a dispensing orifice, two removable reservoirs each containing a single dose of fluid product, a dispensing mechanism, and an actuating mechanism. The reservoirs are closed before the dispensing device is actuated. The body has a mechanism for opening each reservoir and adapted to open the reservoirs during actuation of the device. The reservoirs each form a sealed unit which is separate from said body, each reservoir filled with a respective fluid product and hermetically sealed before installed in the body. The body has a receiving mechanism for lateral installation of the reservoirs in the body.

A fluid dispenser device having a reservoir; a valve; a cocking member movable between rest and primed positions and between primed and dispensing positions, the cocking member includes a set of teeth; a blocking device blocking the cocking member in the primed position; a trigger system controlled by inhaling to release the blocking device; a reservoir support element including a cam opening; and a meshing wheel having a toothed projection co-operating with the set of teeth and a cam projection co-operating with the cam opening. The toothed projection is centered relative to the wheel rotation axis, and the cam projection is offset relative to the axis. The meshing wheel completes a turn when the cocking member moves from its primed towards its dispensing position, such that the cam projection causes the reservoir support element to perform reciprocating axial movement for actuating and returning the valve into its rest position.

Device for distribution of fluid product triggered by inhalation

A dispenser device for dispensing a fluid or powder composition, the dispenser device comprising: a dispenser head () that is provided with a dispenser outlet () that is formed at the end of a hollow sleeve (); an air expeller () for generating a flow of air while the device is being actuated, said air expeller including a piston () that slides in an air chamber () between a rest position and a dispensing position, said air chamber () including a cylindrical body in which said piston () slides in airtight manner; and a reservoir () that contains a single dose of composition, said reservoir () including an air inlet () that is connected to said air expeller (), and a composition outlet () that is connected to said dispenser outlet (), said air inlet () including a composition retainer member () for retaining the composition in the reservoir () until the composition is dispensed, and said composition outlet () being closed by a closure element () that is force fitted in the composition outlet () of the reservoir (); said device further comprising a mechanical opening system () that co-operates with said closure element () so as to expel it mechanically from its closed position while the device is being actuated; said device further comprising an indicator () that, in the rest position before actuation, is in a first state, and that after actuation passes into a second state, the passage from the first to the second state informing the user that the device has been actuated, said first state being a visible state and said second state being a non-visible state, said device including a pusher element () that is secured to said piston (), and on which the user presses during actuation, said dispenser head () including a skirt () that is arranged around said air chamber (), said pusher element (), in its rest position before actuation, projecting axially out from said skirt (), and after actuation, being arranged inside said skirt (), said pusher element () including an indicator () that is visible before actuation and that is not visible after actuation.

A fluid dispenser device including a body and a reservoir, and an opening mechanism. The device includes an inhalation piece and an inhalation trigger system that has a deformable air chamber and a trigger element, such that during inhalation through the inhalation piece, the air chamber is deformed and the trigger element actuates the opening mechanism. The air chamber has a deformable side body; an open first end including a peripheral edge that surrounds an opening forming the inlet of the hollow pouch; and a second end forming the bottom of the hollow pouch. The said second end includes a connection mechanism for connecting the air chamber to the trigger element. The side body is in the form of a bellows having bellows portions arranged axially one after another, the bellows-forming side body has bellows portions having outside and/or inside diameters that are different.

Fluid dispenser device with bellows

A dry powder inhaler including a main body, a plurality of individual reservoirs, such as blisters, each containing a single dose of powder, and disposed one behind another on a flexible strip, and an opening mechanism provided for opening an individual reservoir each time the device is actuated. The device includes first a displacement mechanism adapted to displace an individual reservoir to face the opening mechanism before and/or after each actuation, and a second displacement mechanism adapted to displace an individual reservoir against the opening mechanism on each actuation. The first displacement mechanism having an indexer wheel provided with a recess that receives an individual reservoir, the recess defined by a bottom wall and an inner side wall of said indexer wheel, and by an outer side wall formed on a separate adjustment element assembled on the indexer wheel.

Dry powder inhalator

A dispenser device, including an outlet, air expeller including a piston that slides in an air chamber between rest position and dispensing positions, and a reservoir containing a dose composition. The reservoir includes an air inlet connected to the air expeller, and a composition outlet connected to the outlet, the air inlet including a composition retainer member, and the composition outlet being closed by a closure element force fitted in the composition outlet of the reservoir. A mechanical opening system co-operates with the closure element to expel it from its closed position while the device is actuated. The piston, when in its rest position, co-operates in non-airtight manner with the air chamber so that the air chamber communicates with the atmosphere. The piston includes an inner lip co-operating with a cylindrical surface, the cylindrical surface including fluting co-operating in non-airtight manner with the inner lip in the rest position.

Fluid or powdery product dispensing device

A dispenser device including a dispenser head (), an outlet (); an air expeller (), and a reservoir ().
