Device for the inhalation-synchronized dispensing of a fluid product

An inhalation-synchronised fluid product dispenser device comprising a body provided with a mouthpiece, a product reservoir containing a fluid product and a propellant gas being mounted to slide axially relative to said body, a metering valve, comprising a valve member movable between a rest position and an actuation position, being assembled on said reservoir for selectively dispensing the fluid product on each actuation, said device further comprising:

• a blocking element that is movable and/or deformable between a blocking position in which said metering valve cannot be actuated, and an actuation position in which said metering valve can be actuated;
• a trigger element that is movable and/or deformable between a locking position in which it the trigger element blocks said blocking element in the blocking position, and a release position wherein the trigger element does not block said blocking element;
• an inhalation-controlled trigger system comprising an inhalation-sensitive member that is deformable and/or movable under the effect of inhaling, said inhalation-sensitive member cooperating with said trigger element, such that when said inhalation-sensitive member is deformed and/or moved, said inhalation-sensitive member it moves and/or deforms said trigger element towards the release position, thus allowing said blocking element to move and/or deform from the blocking position towards the actuation position;
• an actuating member cooperating with said blocking element, such that in the blocking position of said blocking element, said blocking element prevents said actuating member from moving axially, and in the actuation position of said blocking element, said blocking element enables said actuating member to move axially;
• a cover fixed on said body;
• a push member cooperating with said actuating member and mounted to slide axially in said cover;
• a spring disposed between said cover and said push member;
• wherein, before inhalation, said push members out of contact with said reservoir, such that the force exerted on said push member by said spring is not transmitted to said reservoir, and during inhalation, said push member moves axially with said actuating member so as to come into contact with said reservoir and move said reservoir axially in said body so as to actuate said metering valve.
