Abstract
A fluid dispenser comprising a fluid reservoir (111) of variable volume, and a dispensing orifice (130), said reservoir being provided with at least one deformable actuating wall (112) urged by resilient means (15) into a rest position corresponding to the reservoir having its maximum volume, said dispenser being characterized in that the resilient means (15) are situated outside the reservoir (111), not in contact with the fluid.
Claims24
A fluid dispenser comprising a fluid and air reservoir (111) of variable volume, and a dispensing orifice (130), said reservoir being provided with at least one deformable actuating wall (112) urged by resilient means (15) into a rest position corresponding to the reservoir having its maximum volume containing both fluid and air, said dispenser being characterized in that the resilient means (15) are situated outside the reservoir (111), not in contact with the fluid.
A fluid dispenser comprising:
- a reservoir of variable volume, including a first volume and a second volume that is greater than the first volume, the reservoir comprising at least one deformable actuating wall;
- a dispensing orifice;
- and
- a resilient member;
- wherein the resilient member, when in a relaxed state, urges the at least one deformable actuating wall to a position corresponding to the reservoir having the second volume and in which the reservoir contains fluid and air;
- and
- wherein the resilient member is disposed outside the reservoir so as not to contact the fluid.
