Abstract: A fluid dispenser device with a body (1), and an axially movable dispenser head (2). The body receives a reservoir (10) having a tube (11) with a proximal axial opening (12) closed by a stopper (20) and adapted to slide in leaktight manner in the tube (11). The dispenser head includes a cannula (4) connected at one end to the dispenser orifice (3), and provided at its other end with a perforating tip (5) for perforating the stopper. The cannula is inserted into a cannula support (9) secured to the dispenser head and including a borehole with an inside diameter equal to, or a little greater than, the outside diameter of the cannula. The distal end of the cannula support (9) has a projection extending inwards and an inside diameter equal to, or a little less than, the outside diameter of the cannula.

Abstract: A fluid dispenser device with a body (1) and an axially movable dispenser head (2). The body receives a reservoir (10) that has a hollow tube (11) having a proximal axial opening (12) closed by a stopper (20) that slides in leaktight manner in the tube during actuation. The dispenser head includes a cylindrical cannula (4) connected to the dispenser orifice (3) and a perforating tip (5) with an opening (6) for perforating the stopper. The stopper has a radial wall (22) perforated by the cannula during actuation, the opening of the cannula defining a peripheral edge (7) around the opening and that includes an axial end and a proximal end separate by an axial extent of the opening (6). Two doses of fluid are dispensed during two successive actuations, the axial extent of the opening being less than the axial thickness of the radial wall of said stopper.
