A fluid dispenser device having a reservoir (1), a metering valve (2) having a valve member (3), and an automatic trigger system for actuating the valve. The trigger system has a resilient element (10) moved manually into a cocked position. The trigger system releases the resilient element (10) and moves to an actuating position by moving the valve member (3) towards its dispensing position. The resilient element (10) is returned manually to its rest position. The fluid dispenser device includes a valve member release system co-operating with the reservoir (1) or with the valve member (3) so that, after dispensing the fluid, the valve member (3) is released from the force exerted by the resilient element (10), so that, after the device is actuated, the valve member (3) is returned to its rest position by the return spring of the valve, independently of the position of the resilient element.
