Abstract
A fluid product dispenser having a reservoir of fluid product defining a moveable actuating wall, a distribution orifice, and a spring structured to act on the actuating wall to produce a state of maximum volume of the reservoir. The spring co-operates with an arming element structured to cause the spring from an initial state in which the spring does not bias the actuating wall to a state in which the spring biases the actuating wall.
Claims23
A fluid product dispenser comprising:
- a reservoir of fluid product comprising a varying volume, the reservoir defining an actuating wall structured to be moved during operation to reduce the volume of the reservoir from a maximum volume state;
- a distribution orifice;
- and
- a spring structured to return the actuating wall to the maximum volume state of the reservoir;
- the spring cooperating with an arming device and structured to bias the actuating wall in the maximum volume state starting from an initial state in which the spring does not bias the wall.

A fluid product dispenser comprising:
- a reservoir of fluid product comprising a varying volume, the reservoir defining an actuating wall structured to be moved to reduce the volume of the reservoir from a maximum volume state;
- a distribution orifice;
- a spring structured to return the actuating wall to the maximum volume state of the reservoir;
- and
- an arming device that, when armed, moves the actuating wall to the maximum volume state of the reservoir;
- the spring being inactive so as not to bias or move the actuating wall until the arming device has first moved the actuating wall in the maximum volume state.

A fluid product dispenser comprising:
- a reservoir of fluid product comprising a varying volume, the reservoir defining an actuating wall structured to be moved to reduce the volume of the reservoir from a maximum volume state;
- a distribution orifice comprising a removable sealing organ;
- and
- an arming device structured to move the actuating wall to the maximum volume state of the reservoir;
- the volume of the reservoir being substantially unchanged upon removal of the sealing organ until the arming device moves the actuating wall.

A fluid product dispenser comprising:
- a reservoir of fluid product comprising a varying volume, the reservoir defining an actuating wall structured to be moved between a minimum volume state and a maximum volume state;
- a distribution orifice;
- an arming device movable between two positions, a first position in which the actuating wall is in the minimum volume state and a second position in which the arming device has moved the actuating wall to the maximum volume state;
- a spring that returns the actuating wall to the maximum volume state, the spring only operant applying a force on the wall after the arming device has moved to the second position.

A fluid product dispenser comprising:
- a reservoir of fluid product comprising a varying volume, the reservoir defining a actuating wall structured to be moved to reduce the volume of the reservoir from a maximum volume state;
- a distribution orifice;
- a spring;
- and
- an arming device structured to move the actuating wall to the maximum volume state and to move the spring to an active state wherein the spring applies a force to return the wall to the maximum volume state initially moved by the arming device.

A product dispenser comprising:
- a reservoir of product comprising a varying volume, the reservoir defining an actuating wall structured to be moved during operation to reduce the volume of the reservoir from a larger volume state;
- a distribution orifice;
- first means for applying a force to the actuating wall so as to expand the reservoir towards the larger volume state;
- and
- second means for arming the first means so that the first means applies a force to the actuating wall so as to expand the reservoir towards the larger volume state only after the second means has armed the first means;
- and
- wherein the first means does not bias the actuating wall before the second means has armed the first means.
