Claim 0:
1. An inhalation-synchronized fluid dispenser device comprising a device body provided with a mouthpiece, a fluid reservoir containing a fluid and a propellant gas being mounted to slide axially in said device body, a metering valve including a valve member being assembled on said reservoir for selectively dispensing the fluid, said device further comprising:
a blocking element that is movable and/or deformable between a non-actuation position in which said metering valve cannot be actuated, and an actuation position in which said metering valve can be actuated, said blocking element, in its non-actuation position, co-operating firstly with the device body and secondly with the reservoir so as to prevent said reservoir from moving axially in the device body; and
an inhalation-controlled trigger system including an inhalation-sensitive member that is deformable and/or movable under the effect of inhaling, wherein, when said inhalation-sensitive member, is deformed and/or moved, is configured to move and/or deform said blocking element from its non-actuation position towards its actuation position;
said device includes an actuator that is fastened on said reservoir, said actuator comprising a proximal wall that is fastened on an end of the reservoir, an actuator body that slides axially past said proximal wall, and a spring that is arranged between said proximal wall and a distal wall of said actuator body, said actuator body sliding axially past said proximal wall between a rest position and a cocked position in which said spring is compressed, such that on said inhalation-controlled trigger system being actuated, said compressed spring moves said reservoir axially in said device body so as to actuate said metering valve; and
wherein said blocking element is a blocking ring that is fastened on said reservoir, and that includes at least one axial tab co-operating with a shoulder that is secured to said device body so as to prevent said reservoir from moving axially in said device body.
