Fluid product dispensing device
First Claim
1. A fluid dispenser device comprisinga reservoir (1) containing fluid and a propellant gas,a metering valve (2) mounted on said reservoir and comprising a metering chamber and a valve member (3) mounted to move between a dispensing position and a rest position, andan automatic trigger system for actuating said valve, said trigger system comprising a resilient element (10) formed by or secured to a spring, said resilient element capable of being moved manually by the user into a cocked position in which it is held under tension, actuation of the trigger system releasing said resilient element (10) which then moves to an actuating position while exerting a force adapted to moving the valve member (3) of the valve (2) towards its dispensing position, said resilient element (10) then being returned manually by the user from its actuating position to its rest position in which it no longer urges said valve member towards its dispensing position,said fluid dispenser device further comprises a mechanical valve member release system which co-operates with the reservoir (1) or with the valve member (3) of the valve (2) so that, after dispensing the fluid contained in the metering chamber of the valve, said valve member (3) is mechanically released from the force exerted by said resilient element (10) of the trigger system, so that, after the device is actuated, said valve member (3) is returned to its rest position by the return spring of the valve, independently of the position of said resilient element,said valve member release system comprising a locking element (20) co-operating with one of the valve member (3) and the fluid reservoir (1), said locking element (20) being mounted to move between a locking position, in which the valve member (3) can be brought into its dispensing position by said resilient element (10) of the trigger system, and an unlocking position, in which the valve member (3) is brought into its rest position independently of the position of said resilient element (10), said locking element (20) being urged to its unlocking position after the trigger system has been actuated,the valve member release system including a retaining member (30) that can be moved from a retaining position in which it retains said locking element (20) in its locking position, and a non-retaining position in which it does not retain said locking element (20) in its locking position, said retaining member (30) being moved towards its non-retaining position when the valve member (3) reaches its dispensing position,said valve member release system including a control element (40) co-operating firstly with the valve member (3) and secondly with the retaining member (30) so that when the valve member (3) reaches its dispensing position, the control element (40) makes it possible to move the retaining member (30) to its non-retaining position so that the locking element (20) is moved into its unlocking position, and the valve member is returned to its rest position by the return spring of the valve, said control element being a sleeve surrounding said retaining member externally.

Abstract
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.

15. A fluid dispenser device comprising:
-
a reservoir containing a fluid; a metering valve mounted on the reservoir; a valve member moveable between a dispensing position and a rest position; a resilient member; wherein when the resilient member is cocked, actuation of a trigger releases the resilient member so that it exerts a force on the valve member to move the valve member from the dispensing position to the rest position; and wherein a release system mechanically releases the valve member from the force exerted by the resilient member by returning the valve member to its rest position independently of the position of the resilient member, and wherein the fluid dispenser device further comprises; a locking element attached to the reservoir; a retaining member; and a control member surrounding externally the reservoir and the locking element; wherein the control member comprises a first diameter portion and a second diameter portion, the first diameter being larger than the second diameter and wherein the locking element comprises a third diameter portion and a fourth diameter portion, the third diameter being larger than the fourth diameter; wherein before the trigger is actuated, the retaining member is engaged with the fourth diameter portion of the locking element and contacts the control member at the second diameter portion; and wherein after the trigger is actuated, the retaining member contacts the third diameter portion of the locking element and the first diameter portion of the control member. - View Dependent Claims (16, 17)
