An inhaler comprising a housing defining a chamber to receive a strip having a plurality of blisters each containing a dose of medicament for inhalation by a user is disclosed. It comprises an actuating lever and a blister strip drive member rotatably mounted in the chamber to sequentially move each blister into a blister opening position. The blister strip drive member and the actuating lever comprise a drive gear and a drive gear element, respectively, that cooperate to effect rotation of the blister strip drive member in response to rotation of the actuating lever. The drive gear and drive gear element are disposed on the outside of the housing remote from the chamber.

An inhaler comprising a housing defining a chamber to receive a strip having a plurality of blisters each containing a dose of medicament for inhalation by a user is disclosed. It comprises an inhaler comprising a housing to receive a strip having a plurality of blisters, each blister having a puncturable lid and containing a dose of medicament for inhalation by a user, a mouthpiece mounted to the housing and through which a dose of medicament is inhaled by a user, a blister piercing member mounted for rotation about a first axis and an actuating mechanism including an actuating lever mounted for rotation about a second axis to sequentially move each blister into alignment with the blister piercing member, wherein the actuating lever co-operates with the blister piercing member so that the blister piercing member pivots about said first axis in response to rotation of the actuating member from an initial position about the second axis to puncture the lid of an aligned blister so an airflow through the blister is generated to en-train the dose contained therein and carry it, via the mouth-piece, into the users airway when a user inhales through the mouthpiece. The inhaler comprises an actuating lever load control member to control the force that must be applied to the actuating lever to cause it to rotate from its initial position such that a biasing force is applied to the actuating lever throughout all, or at least a substantial portion of, the stroke of the actuating lever.

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.

A fluid dispenser device including a body (10) and at least one cover element (11, 12) that is mounted to pivot on said body (10) between a closed position and an open position, said device including at least one individual reservoir containing a single dose of fluid, such as powder, opening means (80) being provided for opening an individual reservoir each time the device is actuated, said device including movable support means (50) that are adapted to move an individual reservoir against said opening means (80) on each actuation, said movable support means (50) being displaceable between a non-dispensing position and a dispensing position, said movable support means (50) being urged towards their dispensing position by resilient means (70), such as a spring or a spring blade, and being held in their non-dispensing position by blocking means that are released by the user inhaling, said device including a cocking member (800) that co-operates with said resilient means (70) and with a cam surface (51) that is formed on said movable support means (50), said cocking member (800) and said resilient means (70) being assembled in a housing provided in a housing piece (700) connected to a cover element (12).

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.
