Device for dispensing combined doses of fluid product
First Claim
1. A nasal fluid dispense spray device comprising a body (1), dispensing means (30) for dispensing the fluid, a first reservoir (10) containing a first fluid and a second reservoir (20) containing a second fluid, the first and second fluids to be mixed prior to dispensing so as to form one or more doses of fluid to be dispensed, said fluid dispenser device being characterized in that it further comprises a mixture-forming system for mixing the first and second fluids in one of said reservoirs (10, 20), said mixture-forming system having a manual actuating element (50) that is mounted to move in a direction that is substantially perpendicular to the direction in which the fluid is dispensed, said manual actuating element (50) being actuatable with one hand and acting, after said first and second fluids have been mixed, to actuate the dispensing means (30) for dispensing the fluid, without any further manipulation of the device being necessary;
- said actuating element comprising energy accumulation means for preventing the actuating element from being actuated until a threshold force is applied to the actuating element.

Abstract
A fluid dispenser device comprising a body (1), dispensing means (30) for dispensing the fluid, a first reservoir (10) containing a first fluid and a second reservoir (20) containing a second fluid, the first and second fluids being to be mixed prior to dispensing so as to form one or more doses of fluid to be dispensed, said fluid dispenser device being characterized in that it further comprises a mixture-forming system for mixing the first and second fluids in one of said reservoirs (10, 20), said mixture-forming system having a manual actuating element (50) that is mounted to move in a direction that is substantially perpendicular to the direction in which the fluid is dispensed, said manual actuating element (50) being actuatable with one hand and acting, after said first and second fluids have been mixed, to actuate the dispensing means (30) for dispensing the fluid, without any further manipulation of the device being necessary.

16. A fluid spray device comprising a body, dispensing means for dispensing the fluid, a first reservoir containing a first fluid and a second reservoir containing a second fluid, the first and second fluids to be mixed prior to dispensing so as to form one or more doses of fluid to be dispensed, said fluid dispenser device being characterized in that it further comprises a mixture-forming system for mixing the first and second fluids in one of said reservoirs, said mixture-forming system having a manual actuating element that is mounted to move in a direction that is substantially perpendicular to the direction in which the fluid is dispensed, said manual actuating element being actuatable with one hand and acting, after said first and second fluids have been mixed, to actuate the dispensing means for dispensing the fluid, without any further manipulation of the device being necessary;
- and
wherein the mixture-forming system comprises a first piston mounted to slide in the first reservoir, a passageway interconnecting the two reservoirs, and one or more pegs co-operating firstly with said piston and secondly with the actuating element, in particular via a cam surface on said element, which cam surface transforms the substantially lateral motion of the actuating element into axial motion of the first piston so as to transfer the fluid contained in the first reservoir to the second reservoir through said passageway.

17. A nasal fluid spray device comprising:
-
a body, a piston that dispenses the fluid; a first reservoir comprising a first fluid; a second reservoir comprising a second fluid; a passageway for conveying the first fluid to the second fluid prior to dispensing so as to form one or more doses of mixed fluid in the second reservoir; and a manual actuating element mounted to move in a direction substantially perpendicular to the direction in which the fluid is dispensed, the manual actuating element configured to be actuated with one hand and acting, after the first and second fluids have been mixed, to actuate the piston to dispense the fluid;
the actuating element comprising an energy accumulation elastic member that prevents the actuating element from being actuated until a threshold force is applied to the actuating element. - View Dependent Claims (19)
