Abstract

A packaging unit for a product such as mascara includes an applicator and a reservoir provided with at least one wiper. The applicator has a handle and at least one tuft of bristles implanted parallel to the median plane of this handle. The wiper is arranged so as to wipe the bristled part along the axis of the bristles.

Claims

1. A packaging unit for a liquid to pasty product to be applied to keratinous fibers, comprising:

a reservoir for the product and provided with a wiper; and

an applicator having a planar handle and a bristly part having bristles, said applicator being mountable on said reservoir for closing said reservoir, wherein said wiper has a shape complementary to that of said bristly part, wherein said wiper is positioned so as to wipe the bristles along their longitudinal axes, and wherein said bristly part has at least one tuft of bristles implanted parallel to the plane of the handle.

2. A packaging unit according to claim 1, wherein a width of the free end of the tuft of bristles, measured along a first direction parallel to the plane, is at least equal to a quarter of an arc formed of the fibers, the bristles being capable of applying the product to the keratinous fibers along a longitudinal axis of the fibers.

3. A packaging unit according to claim 1 including means for preventing the clogging of the wiper.

4. A packaging unit according to claim 3 wherein said clogging preventing means comprises a flexible pouch contained in the reservoir, said flexible pouch containing the product.

5. A packaging unit according to claim 1 wherein said wiper is flocked.

6. A packaging unit according to claim 1 wherein said wiper is formed of a material chosen from elastomers and thermoplastic materials.

7. A packaging unit according to claim 1 wherein said part with bristles has an overall effective length capable of providing an optimum loading of the fibers.

8. A packaging unit according to claim 7 wherein the length of said part with bristles ranges from 5 to 40 mm.

9. A packaging unit according to claim 1 wherein said handle of the applicator is mounted on a cap capable of being catch-engaged on the reservoir.

10. A packaging unit according to claim 1 including means at said handle for sealing said reservoir.

11. A packaging unit according to claim 1 wherein said packaging unit is made solely of plastic materials.

12. A packaging unit according to claim 1 wherein said wiper comprises means for wiping ends of the bristles along an internal wall of the wiper during inclination of the applicator.

13. A packaging unit according to claim 1 wherein said product is mascara.

14. A packaging unit for a liquid to pasty product to be applied to keratinous fibers, comprising:

a reservoir for the product and provided with a wiper; and

an applicator having a planar handle and a bristly part having bristles, said applicator--being mountable on said reservoir for closing said reservoir, wherein said wiper has a shape complementary to that of said bristly part and wherein said wiper is positioned so as to wipe the bristles along their longitudinal axes, including means for creating a low pressure in the reservoir during the removal of the applicator from this reservoir so that the bristles are loaded with the product.

15. A packaging unit according to claim 14 wherein said low pressure creating means include reliefs formed on an internal wall of the wiper.

16. A packaging unit for a liquid to pasty product to be applied to keratinous fibers, comprising:

a reservoir for the product and provided with a wiper; and

an applicator having a planar handle and a bristly part having bristles, said applicator--being mountable on said reservoir for closing said reservoir, wherein said wiper has a shape complementary to that of said bristly part and wherein said wiper is positioned so as to wipe the bristles along their longitudinal axes, wherein said wiper has, in cross-section thereof in a plane perpendicular to a direction of movement of the handle during wiping, an oblong opening for the passage of the bristled part.

17. A packaging unit according to claim 16 wherein a fixed end of the part with bristles is situated in the vicinity of the opening of the wiper.

18. A packaging unit according to claim 16 wherein the wiper has reliefs at said opening.

19. A packaging unit for a liquid to pasty product to be applied to keratinous fibers, comprising:

a reservoir for the product and provided with a wiper; and

an applicator having a planar handle and a bristly part having bristles, said applicator--being mountable on said reservoir for closing said reservoir, wherein said wiper has a shape complementary to that of said bristly part and wherein said wiper is positioned so as to wipe the bristles along their longitudinal axes, wherein said wiper has at least one longitudinal slot.
