A fluid dispenser device having a body (1), a fluid reservoir (3) containing two half-doses, a dispensing mechanism that dispenses a half-dose of fluid upon actuation, and an energy accumulation mechanism (50, 51, 55) that accumulates energy in the hand of the user and released suddenly so that each of the half-doses is dispensed in full. The dispensing mechanism includes a dispensing member (8) mounted to slide in the reservoir (3) for dispensing the fluid, an actuating element (5) mounted to move between a rest position and an actuating position and on which the user exerts an actuating force to move the dispensing member (8) inside said reservoir (3). The actuating element is mounted to move in a direction substantially transverse to the direction in which the dispensing member (8) moves, and a dose-splitting mechanism (7, 12) dispenses a half-dose of fluid each time the dispensing mechanism is actuated.

The invention claimed is: 1. A nasal fluid spray device comprising a body (1), a fluid reservoir (3) containing two half-doses of fluid, each half-dose being for dispensing in a respective nostril, a dispensing orifice (30), and dispensing means (5, 6, 7, 8, 9) for dispensing a respective half-dose
The invention claimed is: 1. A nasal fluid spray device comprising a body (1), a fluid reservoir (3) containing two half-doses of fluid, each half-dose being for dispensing in a respective nostril, a dispensing orifice (30), and dispensing means (5, 6, 7, 8, 9) for dispensing a respective half-dose of fluid each time the dispensing means are actuated, said dispensing means being implemented so that each of the half-doses of fluid can be dispensed during a respective one of two successive occasions on which the dispensing means are actuated, it being possible to actuate the dispensing means on said successive occasions by the user of the device using a single hand, the nasal spray device further comprising energy accumulation means (50, 51, 55) adapted to accumulate energy in the hand of the user, said energy being released suddenly as of a predetermined force exerted by the hand of the user on said dispensing means, thereby guaranteeing that each of the half-doses is sprayed in full, said dispensing means comprising a dispensing member (8) mounted to slide in said reservoir (3) for dispensing the fluid, and dose-splitting means (7, 12) for dispensing a half-dose of fluid each time the dispensing means are actuated, said nasal spray device being characterized in that the dispensing means further comprise an actuating element (5) mounted to move between a rest position and an actuating position, and on which the user exerts an actuating force to move said dispensing member (8) inside said reservoir (3), said actuating element being mounted to move in a direction substantially transverse to the direction in which the dispensing member (8) moves. 2. A device according to claim 1, in which the dose-splitting means (7, 12) are secured to said dispensing member (8), and are formed by a first projection (7) co-operating with the actuating element (5) when the device is actuated for the first time to dispense the first half-dose of fluid, and a second projection (12) adapted to move out of the way while the first half-dose of fluid is being dispensed, said second pair of projections (12) co-operating with said actuating element (5) after the first half-dose has been dispensed, so as to dispense the second half-dose when the device is actuated for the second time. 3. A device according to claim 1, in which said dose-splitting means (7, 12) co-operate with said actuating element (5) to return it to its rest position after the first half-dose has been dispensed. 4. A device according to claim 1, in which said actuating element (5) has a cam surface (6) co-operating with said dispensing member (8), preferably via said dose-splitting means (7, 12). 5. A device according to claim 1, in which said energy accumulation means (50, 51, 55) are exempt from breakable bridges of material. 6. A device according to claim 5, in which said energy accumulation means (50, 51, 55) are provided between said actuating element (5) and said body (1) of the device. 7. A device according to claim 1, in which said energy accumulation means comprise an elastically deformable element (50) which deforms when it is subjected to said predetermined force. 8. A device according to claim 1, in which said energy accumulation means comprise an elastically deformable catch (50) provided on one of two elements (5, 1; 8, 1; 5, 8) that move relative to each other while the device is being actuated, said elastically deformable catch (50) co-operating with the other of said two elements that move relative to each other to prevent them from moving relative to each other until a predetermined force is applied that is adapted to deform said elastically deformable catch (50). 9. The device according to claim 1, wherein the dispensing member is a piston mounted to slide in the reservoir for dispensing the fluid.
