Abstract
An inhalation-synchronized fluid dispenser device having a body provided with a mouthpiece, a fluid reservoir containing a fluid and a propellant gas mounted to slide axially, a metering valve including a valve member assembled on the reservoir for selectively dispensing the fluid. The device also includes an actuator element movable and/or deformable between a non-actuation position and an actuation position; and an inhalation-controlled trigger system including an inhalation-sensitive member deformable and/or movable under the effect of inhaling so as to move and/or deform the actuator element from its non-actuation position towards its actuation position. The actuator element is a locking element that, in its non-actuation position, enables the valve member of the metering valve to move axially in the body together with the reservoir, preventing said metering valve from being actuated when the reservoir is moved axially in the body without inhaling.
