Claims18
Fluid product dispenser comprising:
- a variable volume reservoir (12) comprising a deformable wall (14) and a mobile wall (11), the mobile wall being movable in order to reduce the volume of the reservoir by deformation of the deformable wall,
- a distribution orifice (32), and
- actuation means (2) to move the mobile wall (11) of the reservoir, wherein the actuation means rotate and comprise a thread (21) engaged with the mobile wall of the reservoir.
Fluid product dispenser comprising:
- a variable volume reservoir (12) comprising a deformable wall (14) and a mobile wall (11), the mobile wall being movable in order to reduce the volume of the reservoir by deformation of the deformable wall;
- a distribution orifice (32);
- and
- an actuating cylinder having an internal thread coupled to the mobile wall (11) of the reservoir, wherein the actuating cylinder is rotatable so as to move the mobile wall in an axial direction of the thread.
