Abstract

A device (1) for applying a make-up product for keratinous fibers, in particular eyelashes, includes a handle (8) of a substantially flat profile, whose first end (10) carries an applicator element (50) having a free end. The applicator element is formed by a blade (6) defining a unitary structure elastically deformable in a multidirectional mode, and disposed substantially parallel to a plane of the handle. The blade (6) has two main sides (51, 52), the surface of at least one of the sides having reliefs (53) capable of retaining some of the product after a substantial portion of the surface has been brought into contact with the product. The width of the free end, measured along a first direction (X) parallel to the plane, is at least equal to a quarter of the average width of an arc of eyelashes.

Claims

1. A device for applying a make-up product for eyelashes, comprising:

a substantially flat handle;

an applicator element having a free end and being mounted to a first end of said handle, said applicator element being formed by a blade defining a unitary structure elastically deformable in at least two orthogonal directions and disposed substantially parallel to a plane of the handle, wherein said blade has two main sides, wherein a width of said free end, measured along a first one of said orthogonal directions which is parallel to said plane, is at least equal to a quarter of an average width of an arc of the eyelashes to which the make-up product is to be applied; and

reliefs formed on a surface of at least one of the main sides and being capable of retaining some of the product after a substantial portion of said surface has been brought into contact with the product.

2. An application device according to claim 1, wherein the width is from 0.75 cm to 3 cm.

3. An application device according to claim 1, wherein the free end of the applicator element has a thickness, measured along a direction perpendicular to said plane, which is no greater than the thickness of said first end of the handle.

4. An application device according to claim 3, wherein said blade has a length, along a second one of said orthogonal directions, ranging from 10 mm to 60 mm.

5. An application device according to claim 4, wherein said length ranges from 10 mm to 30 mm.

6. A device according to claim 1, wherein said elastically deformable material has a hardness in the range of 10 Shore A to 90 Shore D.

7. A device according to claim 1, wherein said applicator element is formed of an elastomeric material chosen from the group of elastomers consisting of polyethylene, polyurethane, polyester, polyether block amides, polyvinyls, terpolymers of ethylene, of propylene and of a diene (EPDM), sequenced polymers of styrene-butadiene (SEBS-SIS), silicone, nitrile and butyl.

8. A device according to claim 1, wherein said blade has prongs at said free end for separating the eylashes after application of the product thereto.

9. A device according to claim 4, wherein the applicator element is formed of at least one block of foam having one of open cells, half-open cells and closed cells.

10. A device according to claim 9, wherein said foam is a foam of one of polyurethane, polyethylene, polyvinyl chloride, polyether, natural rubber and synthetic rubber.

11. A device according to claim 9, wherein said applicator element has an elastically deformable core sandwiched between two foam blocks.

12. A device according to claim 11, wherein the elastically deformable core has a length along the second one of said orthogonal directions greater than the length of the foam blocks between which it is sandwiched, and wherein said core has, adjacent the free end of the applicator element, prongs capable of separating the eyelashes after application of the product.

13. A device according to claim 9, wherein the reliefs are formed by an embossed finish orientated along the second one of said orthogonal directions, said embossed finish being obtained by one of pressing the foam and longitudinal welds.

14. A device according to claim 1, wherein said reliefs are formed by one of grooves, striations, openings passing through at least a part of the thickness of the blade, a flocked coating diamond-shaped bosses, grooves and hollows.

15. A device according to claim 1, wherein said applicator element has a flocked coating over at least a portion of at least one of said main sides.

16. A device according to claim 15, wherein the flocked coating has a mixture of bristles of different characteristics.

17. A device according to claim 1 claim, wherein said free end of the applicator element has a beveled concave shape.

18. A device according to claim 1, wherein an end of the handle opposite to said first end comprises means for separating the eyelashes after application of the product.

19. A device according to claim 18, wherein said separating means comprises a comb.

20. A device according to claim 1, wherein said applicator element is mounted on the first end of the handle by one of bonding and duplex injection molding together with the handle.

21. A device according to claim 1, wherein the handle has an axially curved profile, the blade being disposed along a curve substantially identical with the curve of the handle.

22. A device according to claim 1, wherein the handle comprises two parts articulated around an articulation parallel to said first one of said orthogonal directions.

23. An application device according to claim 4, wherein said length ranges from 15 mm to 20 mm.

24. A device according to claim 1, wherein said elastically deformable material has a hardness in the range of 30 Shore A to 60 Shore D.

25. A device according to claim 15, wherein the flocked coating has a mixture of bristles of different diameters.

26. A device according to claim 25, wherein the flocked coating has a mixture of bristles of different kinds.

27. A device according to claim 26, wherein the flocked coating has a mixture of bristles of different lengths.

28. A device according to claim 27, wherein the flocked coating has a mixture of bristles of different hardnesses.

29. A device according to claim 1 claim, wherein said free end of the applicator element has a beveled convex shape.
