Abstract
A fluid dispenser device including an outlet, a pocket having an interior volume for containing a fluid, the interior volume being delimited at least in part by a movable wall, a reservoir arranged to contain the fluid, a pocket cap, a cavity, a reservoir orifice joining the reservoir and the cavity; wherein the pocket cap is arranged to be mounted by insertion in the cavity of the device so as to be mounted by extending: —by passing through the pocket at least partially while passing through the movable wall or—by going along the pocket at least partially, the device comprising an inlet orifice arranged to insert the pocket cap into the device from the outside of the device and opening into the cavity.
Claims28
A device for dispensing a fluid, comprising:
- a pocket comprising an interior pocket, said interior pocket having an interior volume arranged to contain the fluid,
- a movable wall being arranged to, under the exertion of a pressing pressure on a pressing surface, reduce the interior volume of the interior pocket by deforming and/or by moving,
- an outlet arranged to dispense the fluid, characterized in that the interior volume of the interior pocket is delimited at least in part by:
- a piston integral with a junction wall or a bottom wall,
- a housing of the piston arranged to accommodate the piston and guide it during an axial movement of the piston in the housing,
- the piston or the housing being formed at least in part by at least part of the movable wall, and/or:
- the piston or the housing being in direct contact with a wall forming the pressing surface;
- or
- the piston or the housing being formed at least in part by at least part of the pressing surface;
- the device further comprising:
- a dispensing channel arranged to conduct the fluid from the interior pocket to the outlet;
- and
- a mixer arranged to receive different separate flows of fluid and mix them in the form of a spray at the outlet.
