1. An inhalation-synchronized fluid dispenser device comprising:
a body provided with a mouthpiece, a reservoir containing a fluid and a propellant gas, the reservoir configured to be axially slidable in said body during actuation, a metering valve including a valve member being assembled on said reservoir for selectively dispensing the fluid;
an actuator element that is movable and/or deformable between a non-actuation position wherein the reservoir is axially blocked to preclude said metering valve from being actuated, and an actuation position wherein the reservoir is configured to axially slide in the body to permit said metering valve to be actuated; and
an inhalation-controlled trigger system including an inhalation-sensitive member that is deformable and/or movable under the effect of inhaling, said inhalation-sensitive member, when deformed and/or moved, moving and/or deforming said actuator element from its non-actuation position towards its actuation position;
said actuator element being a blocking element that, in the non-actuation position, co-operates with the body and with the reservoir so as to prevent said reservoir from moving axially in the body, wherein said actuator element is a blocking ring that is fastened on said reservoir and includes at least one axial tab that co-operates with a shoulder that is secured to said body so as to prevent said reservoir from moving axially in said body;
wherein said at least one axial tab is deformable radially outwards so as to pass from the non-actuation position towards the actuation position, a trigger element being provided so as to hold said at least one axial tab in the non-actuation position;
wherein said trigger element is mounted to move between a blocking position that blocks said blocking ring in the non-actuation position, and a release position that does not block said blocking ring; and
wherein said inhalation-controlled trigger system includes a deformable membrane that defines a deformable air chamber, said deformable membrane being fastened to said trigger element, said deformable membrane being deformed during inhaling to move said trigger element from the blocking position towards the release position.
