Abstract: Device for dispensing a fluid product comprising a body (1) having a dispensing opening (12) and a piercing element (4), said body (1) containing a reservoir (10) containing at least two doses of fluid product, said reservoir (10) having a proximal axial opening closed by a membrane (30) and a distal axial opening closed by a piston (20), mounted in a sliding manner in said reservoir (10) in order to dispense a dose of fluid product on each actuation, said reservoir (10) being axially movable with respect to said body (1) between a rest position, in which said piercing element (4) does not pass through said membrane (30), and a dispensing position, in which said piercing element (4) passes through said membrane (30), said membrane (30) being capable of reclosing in a sealed manner after each actuation, when said piercing element (4) comes back out from said reservoir (10), said device comprising a lateral actuation system having an actuating member (50), laterally movable with respect to said body (1) between

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.
