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.

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 spray head for a fluid dispenser device, including a hollow body having a substantially cylindrical sleeve and extending along a longitudinal axis (A), a substantially radial end wall provided with a spray orifice; and a spray profile upstream from the spray orifice. The spray profile includes at least one channel that is non-radial and/or non-axial relative to the longitudinal axis (A). The head, the spray orifice, and the spray profile are made as a single piece, the spray profile including a central pin, the internal end of the central pin, arranged inside the hollow body, being of shape that is conical or frustoconical, so as to guide the fluid towards the at least one non-radial and/or non-axial channel, the internal end forming an outlet valve.
