ABSTRACT:
Fluid dispenser device having a body (1), a fluid reservoir (3), a dispensing member, such as a pump or a metering valve having a piston or a valve member that is mounted to move axially, which dispensing member is fitted to the reservoir (3), and an actuating element (5) mounted to move between a rest position and an actuating position, for actuating the dispensing member and thus for selectively dispensing the fluid contained in the reservoir (3). In the fluid dispenser device, the direction in which the actuating element (5) moves is different from, and preferably perpendicular to, the axial direction in which the piston or the valve member of the dispensing member moves. The device further includes a force-regulating mechanism that predetermines the force to be exerted on the actuating element (5) for actuating the dispensing member, the force being constant each time the device is actuated, independently of the quantity of fluid contained in the reservoir (3) and/or of the resistance of the piston or of the valve member of the dispensing member.
