Fluid dispenser device
View Patent ↗A fluid dispenser device having an outlet valve ( 22, 36 ) including a seat ( 22 ) and a movable member ( 36 ) that is urged in leaktight manner against the seat ( 22 ), the dispenser device being switchable between a locked position and a working position in which the outlet valve ( 22, 36 ) is closed, the dispenser device not being actuatable in the locked position, but being actuatable in the working position, the movable member ( 36 ) being urged by at least one resilient element ( 42 ) against the seat ( 22 ) in the working position, the dispenser device being characterized in that, in the locked position, the movable member ( 36 ) is urged against the seat ( 22 ) by at least one bearing element ( 41 ) other than the at least one resilient element ( 42 ).
1. A fluid dispenser device having an outlet valve ( 22 , 36 ) comprising a seat ( 22 ) and a movable member ( 36 ) that is urged in leaktight manner against the seat ( 22 ), the dispenser device being switchable between a locked position and a working position in which the outlet valve ( 22 , 36 ) is closed, the dispenser device not being actuatable in the locked position, but being actuatable in the working position, the movable member ( 36 ) being urged by resilient means ( 42 ) against the seat ( 22 ) in the working position, the dispenser device being characterized in that, in the locked position, the movable member ( 36 ) is urged against the seat ( 22 ) by bearing means ( 41 ) other than the resilient means ( 42 ).
2. A dispenser device according to claim 1 , in which the bearing means ( 41 ) are substantially rigid, such that they are not resilient.
3. A dispenser device according to claim 1 , in which the resilient means ( 42 ) are relaxed in the locked position, such that they are not subjected to any stress or deformation.
4. A dispenser device according to claim 1 , in which the resilient means ( 42 ) are formed of plastics material.
5. A dispenser device according to any claim 1 , in which switching between the locked position and the working position is generated by relative movement between at least a portion ( 36 ) of the outlet valve and the resilient means ( 42 ).
6. A dispenser device according to claim 5 , in which the relative movement is turning movement.
7. A dispenser device according to claim 6 , further including a pusher ( 2 ) on which the user presses so as to actuate the dispenser device, the pusher ( 2 ) being turned so as to switch from one of the locked position and the working position to the other of the locked position and the working position.
8. A dispenser device according to claim 1 , in which the resilient means ( 42 ) exert a force along an axis X, the movable member ( 36 ) of the valve being urged against the seat ( 22 ) in the direction of the axis X.
9. A dispenser device according to claim 8 , in which the resilient means ( 42 ) comprise at least two resilient elements that are distributed about the axis X, and the bearing means ( 41 ) comprise at least two bearing elements that are distributed about the axis X.
10. A dispenser device according to claim 1 , in which the resilient means ( 42 ) and the bearing means ( 41 ) are made integrally of plastics material.
11. A dispenser device according to claim 1 , in which the movable member ( 36 ) is secured to at least one contact zone ( 38 ) bearing against the resilient means ( 42 ) or the bearing means ( 41 ).
12. A dispenser device according to claim 11 , in which the movable member ( 36 ) is formed integrally with at least one axial tab ( 37 ) defining said at least one contact zone ( 38 ).
