Abstract

Cosmetic treatment method for adding fibers to natural eyelashes, comprising: a) applying an adhesive composition (A) to at least part of the eyelashes, b) bringing fibers (12) borne by an applicator (10) into contact with said adhesive composition (A) present on said eyelashes, c) moving the applicator (10) away from the eyelashes, so as to release fibers (12) which adhere to said eyelashes.

First claim

The invention claimed is:

1. A cosmetic treatment method for adding fibers to natural eyelashes, comprising:
a) applying an adhesive composition to at least part of the eyelashes,
b) providing an applicator on which a plurality of fibers are borne, the fibers of the plurality of fibers being substantially parallel to one another on the applicator, the fibers of the plurality of fibers, when borne by the applicator, being not linked to one another other than via the applicator,
c) bringing said plurality of fibers borne by the applicator into contact with the eyelashes and with said adhesive composition present on said eyelashes, the fibers of the plurality of fibers being substantially parallel to the eyelashes when brought into contact with the eyelashes,
d) moving the applicator away from the eyelashes, so as to release fibers which adhere to said eyelashes.

2. The method according to claim 1 , wherein the adhesive composition is applied in step a) to said at least part of the eyelashes in a continuous or discontinuous manner.

3. The method according to claim 1 , wherein the adhesive composition is applied in step a) on the eyelashes, from the roots of the eyelashes, over a length of the eyelashes ranging from about 0.1 mm to about 10 mm.

4. The method according to claim 1 , wherein step c) is carried out by bringing fibers into contact with a top or lower part of an upper fringe of eyelashes.

5. The method according to claim 4 , wherein step c) is carried out by bringing fibers into contact with the same part of the upper fringe of eyelashes, which was treated by the adhesive composition.

6. The method according to claim 4 , wherein step c) is carried out by bringing fibers into contact with the top part of the upper fringe of eyelashes.

7. The method according to claim 1 , wherein the applicator is brought close to the eyelashes in a tangential movement until the fibers contact the adhesive composition.

8. The method according to claim 1 , wherein the fibers of the plurality of fibers are arranged as a bundle of fibers on the applicator.

9. An assembly for the cosmetic treatment of adding fibers to natural eyelashes, for the implementation of the method as defined in claim 1 , comprising:
an adhesive composition (A) to be applied to the eyelashes,
an applicator retaining a plurality of releasable fibers, the applicator having a longitudinal axis, the applicator making it possible to bring the plurality of fibers into contact with the adhesive composition applied to the eyelashes to enable them to adhere to said composition and to release fibers, the fibers of the plurality of fibers, when borne by the applicator, being not linked to one another other than via the applicator,
wherein
the applicator comprises a mechanical system comprising one or more parts that can be moved relative to one another,
the mechanical system is configured to pass from a fiber retaining configuration to a fiber releasing configuration.

10. The assembly according to claim 9 , wherein the applicator retains a mixture of fibers that differ from one another in color.

11. The assembly according to claim 9 , comprising an adhesive applicator for applying the adhesive composition to the eyelashes.

12. The assembly according to claim 11 , the adhesive applicator comprising a flocked end piece.

13. The assembly according to claim 9 , wherein the adhesive composition comprises or is constituted of an adhesive material chosen among pressure sensitive adhesives.

14. The assembly according to claim 9 , wherein the adhesive composition comprises or is constituted of an adhesive material chosen among acrylic polymers or copolymers.

15. Assembly according to claim 9 , wherein the adhesive composition is an acrylates/ethylhexyl acrylate copolymer.

16. An assembly for the cosmetic treatment of adding fibers to natural eyelashes, for the implementation of the method as defined in claim 1 , comprising:
an adhesive composition to be applied to the eyelashes,
an adhesive applicator for applying the adhesive composition to the eyelashes comprising a flocked end piece,
an applicator retaining a plurality of releasable fibers, the applicator having a longitudinal axis, the applicator making it possible to bring the plurality of releasable fibers into contact with the adhesive composition applied to the eyelashes to enable them to adhere to said composition and to release fibers,
wherein
the applicator comprises a mechanical system comprising one or more parts that can be moved relative to one another,
the mechanical system being configured to pass from a fiber retaining configuration to a fiber releasing configuration, and
the mechanical system comprises a spring that grips the fibers between its coils,
wherein
the spring comprises ends attached to actuating levers that are operated manually, and/or
the spring is compressed or released along said longitudinal axis, the applicator having a push button and two abutments near both ends of the spring, one abutment being movable along the longitudinal axis when actuating the push button.

17. The assembly according to claim 16 , wherein one abutment of the applicator is movable along the longitudinal axis when actuating the push button, the other abutment being immobile.
