Abstract

The invention relates to a device for treating the hair and to the corresponding application method, the device ( 2 ) comprising: —two arms ( 5, 6 ) that are able to move relative to one another between a moved-together configuration for treating the hair and a spaced-apart configuration for inserting hair to be treated between said arms, and —a system ( 18 ) for applying a product, comprising an applicator member ( 26 ) for applying the product, the application system ( 18 ) being mounted on one of the arms ( 5 ) and being able to move relative to said arm ( 5 ) between at least two positions generating, while the device ( 2 ) is being used to treat the hair, different respective application pressures of the applicator member ( 26 ) on the hair to be treated.

First claim

The invention claimed is:

1. Device for treating the hair, comprising:
two arms that are able to move relative to one another between a moved-together configuration for treating the hair and a spaced-apart configuration for inserting hair to be treated between said arms,
two heating elements that are each intended to come into contact with the hair and are each disposed on an arm, and
an application system for applying a cosmetic product, comprising a holder and a refill which is mounted on the holder and comprises an applicator member made of a porous material and being soaked with the cosmetic product for applying the cosmetic product in a liquid form on the hair while contacting the hair in the moved-together configuration of the two arms, the application system being mounted on one of the arms, and the holder being able to move relative to said arm between at least two positions generating, while the two arms are in the moved together configuration, different respective application pressures of the applicator member on the hair to be treated,
the arm opposite to the arm on which the application system is mounted comprising a counter bearing surface such that, in at least one position of the holder of the application system, the hair is pressed against the applicator member with a certain pressure by the counter bearing surface while the device is being used to treat the hair,
wherein a surface of the applicator member configured to contact the hair being continuous.

2. Device according to claim 1 , wherein one of the at least two positions generating different application pressures while the two arms are in the moved-together configuration is a contact position for applying the cosmetic product on the hair, and another one of the at least two positions generating different application pressures while the two arms are in the moved-together configuration is a position without contact with the hair to be treated, in which the applicator member is spaced apart from the hair to be treated.

3. Device according to claim 1 , wherein the application system can take up any intermediate position during the use of the device for treating the hair.

4. Device according to claim 1 , wherein each of the arms comprises a half-handle for holding the device and a jaw that comes into contact with the hair to be treated in the moved-together configuration of the arms, the application system extending along the jaw of the arm which carries it.

5. Device according to claim 4 , wherein the application system extends exclusively along the jaw.

6. Device according to claim 1 , wherein the application system is mounted in a depression in the arm which carries it.

7. Device according to claim 1 , wherein the refill is removable and is fixed by complementing shapes.

8. Device according to claim 1 , wherein the refill is accessible regardless of the configuration of the arms and the position of the application system.

9. Device according to claim 1 , wherein the refill is removable in each of the positions of the application system, whether the arms are in the moved-together or spaced-apart configuration.

10. Device according to claim 1 , wherein the application system comprises a lever or a pusher for moving the application system between said positions.

11. Device according to claim 1 , which comprises a return spring for keeping the application system in one of said positions.

12. Device according to claim 1 , which comprises at least one locking device for locking the application system in order to keep the latter in one of said positions.

13. Device according to claim 12 , wherein the locking device comprises a slider that is mounted on the arm which carries the application system, and locks the application system in one of said positions.

14. Device according to claim 12 , wherein the locking device makes it possible to lock the application system in at least two different positions.

15. Device according to claim 1 , wherein the application system is mounted on the arm which carries it by way of a pivot connection.

16. Device according to claim 15 , wherein the arm carrying the application system has a longitudinal axis, the pivot connection allowing the application system to rotate about a rotation axis parallel to the longitudinal axis of the arm which carries the application system.

17. Device according to claim 1 , wherein the application system is able to move along an axis.

18. Method for treating the hair, wherein use is made of a device as defined in claim 1 , and wherein the position of the application system is varied relative to the arm which carries it.

19. Device according to claim 1 , wherein the counter bearing surface has a shape complementary to an application surface of the applicator member with which the hair to be treated comes into contact.
