Patent ID: 8360055

Claim:
A fluid dispenser device, comprising: a body provided with a dispenser orifice; at least one cover element that is movable between a closed position and an open position; a plurality of individual reservoirs each containing a dose of fluid, said reservoirs being formed on a reservoir substrate; movable support means that receive said reservoir substrate, and that are displaceable between a non-dispensing position and a dispensing position; reservoir opening means for opening a respective reservoir each time said opening means are actuated; said reservoir substrate being displaceable, together with said movable support means, between the non-dispensing position, in which it does not co-operate with said opening means, and the dispensing position, in which said opening means open a respective reservoir; loading means for urging said movable support means towards said dispensing position; blocking means for retaining said movable support means in the non-dispensing position; trigger means for releasing said blocking means and for enabling said movable support means, together with said reservoir substrate, to be displaced towards said dispensing position; and said loading means include an elastically-deformable loading element that co-operates with a cam surface that comprises at least two different sloping surfaces, a first cam-surface portion that is adapted to deform and/or load said loading means, and a second cam-surface portion that co-operates with said deformed and/or loaded loading means; said elastically-deformable loading element comprises a compressible spring; and a rod is interposed between said spring and said cam surface, with displacement of the rod against said cam surface compressing or decompressing said spring or compressing and decompressing said spring.
