Fluid dispenser device

1. A fluid dispenser device, comprising: a dispenser orifice; a reservoir containing at least one dose of fluid; at least one piston axially slidable in said reservoir so as to dispense said fluid; a dispenser member co-operating with said piston; and an actuator element co-operating with said dispenser member; wherein said dispenser member is displaceable between a blocking position, preventing said actuator element from being actuated, and a release position in which the actuation of said actuator element displaces said dispenser member so as to dispense a dose of fluid, said dispenser member being displaced manually from the blocking position to the release position before said device is actuated; and

wherein said dispenser member is axially displaceable towards the piston, and said actuator element is a lateral actuator element that is displaced inwardly in a direction that is approximately perpendicular to the axial displacement direction of said dispenser member;

wherein said dispenser member slides axially between said blocking position in which said dispenser member is disposed remote from said piston, and said release position in which said dispenser member is disposed in contact with said piston.

2. A fluid dispenser device according to claim 1 , in which said fluid dispenser device includes a body including said dispenser orifice at one end, and a bottom wall at the other end, said dispenser member projecting from said bottom wall when in the blocking position.

3. A device according to claim 1 , in which said dispenser member includes at least one engagement means co-operating with said actuator element while the actuator element is being actuated.

4. A device according to claim 3 , in which said at least one engagement means includes a projection co-operating with a cam surface of said actuator element.

5. A device according to claim 3 , in which, when the dispenser member is in the blocking position, said at least one engagement means co-operates with the actuator element so as to prevent the actuator element from being actuated.

6. A fluid dispenser device, comprising: a dispenser orifice; a reservoir containing at least one dose of fluid; at least one piston axially slidable in said reservoir so as to dispense said fluid; a dispenser member co-operating with said piston; and an actuator element co-operating with said dispenser member; wherein said dispenser member is displaceable between a blocking position, preventing said actuator element from being actuated, and a release position in which the actuation of said actuator element displaces said dispenser member so as to dispense a dose of fluid, said dispenser member being displaced manually from the blocking position to the release position before said device is actuated; and

wherein said dispenser member is axially displaceable towards the piston, and said actuator element is a lateral actuator element that is displaced inwardly in a direction that is approximately perpendicular to the axial displacement direction of said dispenser member;

wherein said dispenser member includes at least one engagement means co-operating with said actuator element while the actuator element is being actuated;

wherein said at least one engagement means includes two axially offset engagement means, a first engagement means co-operating with the actuator element so as to dispense a first dose of fluid, and a second engagement means co-operating with the actuator element so as to dispense a second dose of fluid.

7. A device according to claim 6 , in which said at least one engagement means includes a projection co-operating with a cam surface of said actuator element.

8. A device according to claim 6 , in which, when the dispenser member is in the blocking position, said at least one engagement means co-operates with the actuator element so as to prevent the actuator element from being actuated.

9. A fluid dispenser device, comprising:

a dispenser orifice;

a reservoir containing at least one dose of fluid;

a piston axially slidable in the reservoir so as to dispense the fluid;

a dispenser member operatively co-operating with the piston so as to slide the piston; and

an actuator element operatively co-operating with the dispenser member so as to axially displace the dispensing member; and

wherein the dispenser member is displaceable between a blocking position that prevents actuation of the actuator element and a release position in which actuation of the actuator element is permitted to displace the dispenser member so as to dispense a dose of fluid; and

wherein the dispenser member is structured to be manually displaced towards the piston from the blocking position to the release position before the device is actuated;

wherein the actuator element is a lateral actuator element that is displaced inwardly in a direction that is approximately perpendicular to the axial displacement direction of the dispenser member; and

wherein the dispenser member comprises a protrusion that operatively engages the actuator element so as to block lateral displacement of the actuator element when the dispenser member is in the blocking position and to slide along a cam surface of the actuator element when the dispenser member is in the release position and while the actuator element is being laterally displaced.

10. The fluid dispenser device according to claim 9 , wherein the dispenser member is manually displaced from the blocking position to the release position by manually moving the dispenser member in an axial direction.
