Abstract: A device for dispensing a fluid product, having a body with a dispensing orifice, two removable reservoirs each containing a single dose of fluid product, a dispensing mechanism, and an actuating mechanism. The reservoirs are closed before the dispensing device is actuated. The body has a mechanism for opening each reservoir and adapted to open the reservoirs during actuation of the device. The reservoirs each form a sealed unit which is separate from said body, each reservoir filled with a respective fluid product and hermetically sealed before installed in the body. The body has a receiving mechanism for lateral installation of the reservoirs in the body.

Abstract: A fluid dispenser device having a reservoir; a valve; a cocking member movable between rest and primed positions and between primed and dispensing positions, the cocking member includes a set of teeth; a blocking device blocking the cocking member in the primed position; a trigger system controlled by inhaling to release the blocking device; a reservoir support element including a cam opening; and a meshing wheel having a toothed projection co-operating with the set of teeth and a cam projection co-operating with the cam opening.
