Abstract

A fluid dispenser device including a body and a cover that pivots between a closed position and an open position and reservoirs each containing a dose of fluid. The reservoirs are arranged on a strip and an opening mechanism is provided. The device includes a movable support to move a reservoir against the opening mechanism. The movable support is movable between a non-dispensing position and a dispensing position. The device includes a strip-rolling system having a drum and an actuator member. The actuator member turning relative to the body in a first direction when the movable support is moved from the non-dispensing position towards the dispensing position, and in a second direction when the movable support is moved from their dispensing position towards the non-dispensing position. The actuator member causes the drum to turn only when turning in the second turning direction.

First claim

1 . A fluid dispenser device including a body and at least one cover element that is mounted to pivot on said body between a closed position and an open position, said device including a plurality of individual reservoirs each containing a single dose of fluid, such as powder, said individual reservoirs being arranged on an elongate strip, opening means being provided for opening an individual reservoir each time the device is actuated, said device including movable support means that are adapted to move an individual reservoir against said opening means-on each actuation, said movable support means being movable between a non-dispensing position and a dispensing position, the device being characterized in that it includes a strip-rolling system comprising a drum and an actuator member, the leading end being fastened to said drum, and said actuator member turning relative to the body in a first turning direction when said movable support means are moved from their non-dispensing position towards their dispensing position, and in a second turning direction, opposite to said first turning direction, when said movable support means are moved from their dispensing position towards their non-dispensing position, said actuator member causing said drum to turn only when turning in said second turning direction.

2 . A device according to claim 1 , wherein said drum is prevented from turning in said first turning direction by non-return means.

3 . A device according to claim 2 , wherein said non-return means comprise a lug that is arranged on a deformable tab, said lug co-operating with a first set of teeth of said drum so as to prevent said drum from turning in said first turning direction, said deformable tab deforming so as to enable said drum to turn in said second turning direction.

4 . A device according to claim 1 , wherein said actuator member includes a flexible tab, said flexible tab co-operating with a second set of teeth of said drum so as to turn said drum in said second turning direction, said flexible tab deforming so as to enable said actuator member to turn relative to said drum in said first turning direction.

5 . A device according to claim 1 , wherein said actuator member includes a rigid finger that co-operates with a control opening in said movable support means.

6 . A device according to claim 1 , including an inhalation trigger system that comprises a deformable air chamber that co-operates with an inhalation piece, and a trigger element that co-operates with said air chamber, such that during inhalation through said inhalation piece, said air chamber is deformed and said trigger element actuates said opening means, such that during inhalation through the inhalation piece, a reservoir is opened by said opening means.

7 . A device according to claim 1 , wherein said opening means include a perforator element that is stationary relative to said main body and that is adapted to cut a closure wall of the reservoir in such a manner that the cut portion(s) does/do not obstruct the opening(s) that is/are formed.
