Abstract:
1. A fluid dispenser device comprising: a body provided with a dispenser orifice; at least one reservoir containing a dose of fluid; movable support means that receive at least one reservoir, and that are displaceable between a non-dispensing position and a dispensing position; reservoir-opening means for opening a reservoir when said reservoir-opening means are actuated; stressing means for urging said movable support means towards said dispensing position, said stressing means including an elastically-deformable spring; blocking means for retaining said movable support means in the non-dispensing position corresponding to a cocked position of said blocking means, said blocking means comprising a blocking element connected to a rod; inhalation trigger means for releasing said blocking means and for enabling said movable support means, together with a reservoir, to be displaced towards said dispensing position at the time a user inhales, said inhalation trigger means comprising a deformable air chamber or pouch connected to said rod of said blocking means; means for modifying an inhalation flow of the user, which, at the start of inhalation, are adapted to use the inhalation flow mainly to actuate said inhalation trigger means, and, at the end of inhalation, are adapted to use the inhalation flow mainly to expel the dose of fluid contained in the reservoir, wherein said means for modifying the inhalation flow comprise a movable element that is deformable and/or displaceable between a plugging position in which it plugs an inhalation air passage, and an unplugging position in which it does not plug said inhalation air passage, said movable element being in its plugging position when the movable support means are in the non-dispensing position, and in its unplugging position when the movable support means are in the dispensing position, wherein said movable element includes at least two branches that are connected to a pivot-forming central zone, a first branch co-operating with the movable support means, and a second branch co-operating in said plugging position with said inhalation air passage.
