Laterally-actuated fluid dispenser device

1. A nasal fluid dispenser device comprising a fluid reservoir ( 10 ), a pump ( 20 ) mounted on the reservoir ( 10 ) for selectively dispensing the fluid, and a nasal dispenser head ( 30 ) structured to be inserted into the nasal passage, the nasal dispenser head connected to said pump and incorporating a dispenser orifice ( 31 ), said device being characterized in that it includes at least two laterally-actuated elements ( 40 , 50 ) distributed around said nasal dispenser head ( 30 ), said laterally-actuated elements ( 40 , 50 ) being displaced simultaneously in a direction that is approximately transverse to the central axis of the device, and each co-operating with a bottom peripheral edge ( 11 ) of said reservoir ( 10 ) so as to exert an axial force thereon; and

wherein the laterally-actuated elements are formed as a one-piece integral construction with the dispenser head.

2. A device according to claim 1 , in which each laterally-actuated element ( 40 , 50 ) is secured to said nasal dispenser head ( 30 ).

3. A device according to claim 1 , in which each laterally-actuated element ( 40 , 50 ) is made in the form of an elastically deformable lever, firstly connected to the nasal dispenser head ( 30 ), and secondly cooperating with the peripheral edge ( 11 ) of the reservoir ( 10 ).

4. A device according to claim 1 , in which each laterally-actuated element ( 40 , 50 ) has a cam surface ( 45 , 55 ) co-operating with the bottom edge ( 11 ) of the reservoir ( 10 ).

5. A device according to claim 4 , in which the cam surface ( 45 , 55 ) is a sloping plane having a slope that varies during displacement of the actuator elements ( 40 , 50 ), said slope being at a maximum at the start of actuation and at a minimum at the end of actuation so that the radial force exerted by the user on the actuator elements ( 40 , 50 ) is transformed into axial force for displacing the reservoir ( 10 ) that is at a maximum at the end of actuation.

6. A device according to claim 1 , in which, after actuation, said laterally-actuated elements ( 40 , 50 ) return resiliently to their rest position.

7. A device according to claim 1 , in which, after actuation, said laterally-actuated elements ( 40 , 50 ) are returned to their rest position by the reservoir ( 10 ) returning to its respective rest position.

8. A device according to claim 1 , in which said device includes two laterally-actuated elements ( 40 , 50 ) that are diametrically opposite each other relative to said nasal dispenser head ( 30 ).

9. The device according to claim 1 , wherein simultaneous actuation of the two laterally-actuated elements results in substantially no transverse force on the fluid reservoir.

10. The device according to claim 1 , wherein the laterally-actuated elements are structured so that, upon simultaneously displacing the laterally-actuated elements in a direction that is approximately transverse to the central axis of the device when dispensing fluid into a nostril, no axial force and no transverse force is applied to the dispenser head inside the nostril.

11. The device according to claim 1 , wherein the dispenser head extends along the central axis of the device such that, upon actuation of the laterally-actuated elements, nasal fluid is expelled from the dispenser head along the central axis of the device.

12. A nasal fluid dispenser device, comprising:

a fluid reservoir containing a fluid;

a pump mounted on the reservoir for dispensing the fluid;

a nasal dispenser head structured to be inserted into the nasal passage, the nasal dispenser head connected to the pump and comprising a dispenser orifice; and

two laterally-actuated elements on opposite sides of the nasal dispenser head, the laterally-actuated elements are actuated in a direction that is substantially transverse to an axial direction of the device, each laterally-actuated element co-operating with a lower edge of the reservoir so as to exert an axial force on the reservoir; and

wherein the two laterally-actuated elements are formed as a one-piece integral construction with the dispenser head.

13. The nasal fluid dispenser according to claim 12 , wherein simultaneous actuation of the two laterally-actuated elements results in substantially no transverse force on the fluid reservoir.

14. The nasal fluid dispenser according to claim 12 , wherein the two laterally-actuated elements are structured so that, upon simultaneously displacing the laterally-actuated elements in a direction that is approximately transverse to the axial direction of the device when dispensing fluid into a nostril, no axial force and no transverse force is applied to the dispenser head inside the nostril.

15. The device according to claim 12 , wherein the dispenser head extends along the axial direction of the device such that, upon actuation of the two laterally-actuated elements, fluid is expelled from the dispenser head along the axial direction of the device.
