Fluid product dispenser

1. A fluid product dispenser comprising:

a reservoir of fluid product defining an actuating wall able to be moved;

a distribution orifice; and

spring means adapted to act on the actuating wall to produce a state of maximum volume of the reservoir, the spring means co-operating with arming means structured to bring the spring means to bias the actuating wall starting from an initial state in which the spring means do not bias the actuating wall; and

wherein the spring means and the arming means are integrally formed.

2. Dispenser according to claim 1 , in which the spring means and the arming means are connected by a deformable zone.

3. Dispenser according to claim 2 , in which the deformable zone is able to form a fold line.

4. Dispenser according to claim 1 , in which the spring means are integrated into the deformable wall.

5. Dispenser according to claim 1 , in which the distribution orifice is sealed by a removable sealing organ.

6. Dispenser according to claim 5 , in which the reservoir contains almost only the fluid product before the removable sealing organ is withdrawn.

7. The dispenser according to claim 1 , in which the arming means is located outside the reservoir.

8. The dispenser according to claim 1 , in which the arming means comprises a pivoting arming organ.

9. A fluid product dispenser comprising:

a reservoir of fluid product defining an actuating wall able to be moved;

a distribution orifice; and

spring means adapted to act on the actuating wall to produce a state of maximum volume of the reservoir, the spring means co-operating with arming means structured to bring the spring means to bias the actuating wall starting from an initial state in which the spring means do not bias the actuating wall; and

wherein the spring means comprise a flexible front plate and a rear plate, the reservoir being situated between the front and back plates, the arming means comprising spacer means able to be positioned between the front plate and the rear plate to separate them from each other, at least locally, the flexible front plate thus being elastically deformable when the rear plate approaches so as to squash the reservoir between them.

10. Dispenser according to claim 9 , in which the spacer means are produced in integral manner by the front plate or the rear plate.

11. Dispenser according to claim 9 , in which the spacer means are movable selectively between an inoperative position in which the two plates extend substantially parallel corresponding to a minimum volume state of the reservoir and an operative position in which the two plates are separated from each other.

12. Dispenser according to claim 9 , in which the spacer means comprise an articulated flap integral with the front plate or back plate respectively at the level of an articulation line and defining a bearing edge intended to come into bearing contact against the rear or front plate respectively, said flap being substantially non-deformable.

13. Dispenser according to claim 9 , in which the plates are fixed together around their peripheries, apart from the level of an open side where the spacer means are located.

14. Dispenser according to claim 9 , in which the reservoir is formed by a flexible pouch set between the front and rear plates.

15. Dispenser according to claim 9 , in which the reservoir is formed by the front and rear plates.

16. Dispenser according to claim 9 , in which the dispensing orifice is closed by a removable sealing organ, common actuating means being provided for consecutively removing the removable sealing organ and positioning the spacer means between the two plates.

17. Dispenser according to claim 16 , in which the common actuating means comprise a strip defining a first extremity connected to the spacer means and a second traction extremity, the removable sealing organ being integral with the strip, such that traction on the strip at the level of the second traction extremity produces, firstly, removal of the removable sealing organ and, secondly, the positioning of the spacer means between the two plates.

18. A fluid product dispenser comprising:

a reservoir of fluid product defining an actuating wall able to be moved;

a distribution orifice; and

spring means adapted to act on the actuating wall to produce a state of maximum volume of the reservoir, the spring means co-operating with arming means structured to bring the spring means to bias the actuating wall starting from an initial state in which the spring means do not bias the actuating wall; and

further comprising a front plate and a rear plate, the reservoir being located between the front and rear plates, the arming means comprising spacer means which can be positioned between the front plate and the rear plate, to separate them from each other, at least locally, the spacer means being elastically deformable so as to allow the front and rear plates to approach each other and thus squash the reservoir located between them.

19. A fluid product dispenser comprising:

a reservoir of fluid product defining an actuating wall able to be moved;

a distribution orifice; and

spring means adapted to act on the actuating wall to produce a state of maximum volume of the reservoir, the spring means co-operating with arming means structured to bring the spring means to bias the actuating wall starting from an initial state in which the spring means do not bias the actuating wall; and

wherein the arming means form the spring means.

20. A fluid product dispenser comprising:

a reservoir of fluid product, the reservoir comprising a moveable actuating wall,

a distribution orifice,

a spring, and

an arming device that arms the spring;

wherein when the spring is unarmed within the dispenser, the spring does not bias the moveable actuating wall, and when the spring is subsequently armed within the dispenser by the arming device, the spring biases the actuating wall and increases the volume of the reservoir; and

wherein the distribution orifice communicates the interior of the reservoir with the exterior of the dispenser, and further comprising a sealing device for sealing off the distribution orifice, the sealing device separate from the arming device.
