Abstract

The present invention relates to an adjustable applicator for fluid product comprising a reservoir for the fluid product to be applied, a stopper carrying application means which are immersed in the fluid product in the reservoir (when the stopper is in place) and a wiping arrangement placed next to the opening of the reservoir, comprising a conduit having a variable transverse section for regulating the amount of product remaining on the applications means when it is withdrawn through the conduit.

According to the invention, in order to vary the section of the conduit, there is provided a wiper of resilient material, means for lateral adjustment of the wiper, which are movable about a fixed articulation point in order rigidly to restrict the wiper in a plane perpendicular to its longitudinal axis as well as means to activate the said means for lateral adjustment.

Use is particularly to the manufacture of make-up articles, and more particularly to mascara applicators.

Claims

1. In an adjustable applicator for fluid product comprising a reservoir for the fluid product, a stopper carrying application means which is immersed in the fluid product when the reservoir is closed by the stopper, and wiping means for said application means, which forms a rigid ring, the diameter of which is adjustable, said application means being passed through said rigid ring when it is withdrawn from said reservoir, the improvement comprising a flexible sleeve of uniform cross-section, which extends through said rigid ring and is supported at its two ends by said reservoir, said flexible sleeve being constricted between its two ends by said rigid ring in order to be urged against said application means and said constricted sleeve presenting to said application means a progressively decreasing inner section which progressively compresses said application means as said application means passes through said flexible sleeve.

2. An improved applicator according to claim 1, wherein said wiping means comprises a plurality of arms, distributed around the periphery of said flexible sleeve, substantially parallel to its axis, but being movable about an articulation, and a rigid sleeve surrounding said arms and urging their free ends against the periphery of said flexible sleeve, the transverse section of said flexible sleeve depending on the displacement of said rigid sleeve in its axial direction.

3. An improved applicator according to claim 2, wherein said arms are disposed in a slightly conical array and wherein said rigid sleeve has a corresponding tapering circular inner surface which cooperates with said arms.

4. An improved applicator according to claim 1, wherein said wiping means are constituted by two arms disposed about said flexible sleeve in a plane perpendicular to its axis, one or more of said arms being articulated at its fixed extremity, and by a slider permitting adjustment of separation of the free ends of said arms by its displacement in the axial direction with respect to said arms.

5. An improved applicator according to claim 4, wherein the surface of said two arms which are in contact with said slider are inclined with respect to the axis of said flexible sleeve, and wherein the surfaces of said slider which cooperate with said surfaces of said two arms are inclined in a complementary way.
