Abstract

The present invention relates to an assembly including: —a styling tool (5), in particular a straightening iron, to be moved along a lock of hair to which water and/or a cosmetic composition has been applied, and—a collecting device (7) coupled to the styling tool so as to collect a runoff generated during the movement of the tool over the hair on account of the presence of water and/or said composition on the hair, the collecting device having a reservoir (9) for picking up the runoff.

First claim

The invention claimed is:

1. Assembly comprising:
a straightening iron to be moved along a lock of hair to which water in a liquid form and/or a cosmetic composition in a liquid or foam form has been applied, the straightening iron comprising:
a bottom jaw and an upper jaw connected together by a hinge, the bottom jaw and the upper jaw being able to move relative to one another between a moved-together configuration for treating the hair and a spaced-apart configuration for inserting the hair to be treated between said jaws, and
at least one heating plate disposed on one of the bottom and upper jaws and intended to come into contact with the hair while the bottom and upper jaws are in the moved-together configuration, and

a collecting device coupled to the bottom jaw so as to collect a liquid or foam runoff generated during the movement of the straightening iron over the hair on account of the presence of water and/or said composition on the hair, the collecting device comprising:
a reservoir for picking up the runoff, the reservoir comprising an opening for collecting the liquid or foam runoff in the reservoir, the reservoir being closed except for the opening that collects the liquid or foam runoff in the reservoir,
a fastening system to couple the collecting device in a removable manner to the bottom jaw, and
a grating disposed on the reservoir in the opening,

the reservoir extending along the straightening iron, on a lateral side of the bottom jaw that is downstream of the heating plate with regard to a direction of movement of the straightening iron over the lock of hair, and laterally relative to the bottom and upper jaws.

2. Assembly according to claim 1 , wherein the grating is disposed in a removable manner on the reservoir.

3. Assembly according to claim 1 , wherein the grating has holes the largest dimension of which is less than or equal to 10 mm.

4. Assembly according to claim 1 , wherein the fastening system is adjustable to the bottom jaw on which it is fastened.

5. Assembly according to claim 1 , wherein the fastening system is configured to couple the collecting device in a removable manner to the bottom jaw by sliding.

6. Assembly according to claim 1 , wherein the fastening system is configured to couple the collecting device in a removable manner to the bottom jaw by snap-fastening.

7. Assembly according to claim 1 , wherein the fastening system is configured to couple the collecting device in a removable manner to the bottom jaw by screwing.

8. Assembly according to claim 1 , wherein the fastening system is configured to couple the collecting device in a removable manner to the bottom jaw with the aid of a closable clamping member.

9. Assembly according to claim 1 , wherein the reservoir of the collecting device has a capacity of between 5 and 20 ml.

10. Assembly according to claim 1 , wherein the reservoir is equipped with a retaining member that forms a barrier to the runoff and causes it to flow into the reservoir through the opening that extends between the straightening iron and the retaining member.

11. Assembly according to claim 10 , wherein the retaining member comprises a strip extending transversely to a plane of the grating.

12. Assembly according to claim 1 , wherein the collecting device is configured to be fastened to either one side of the straightening iron or the other in order for the latter to be used by left-handed or right-handed persons.

13. A cosmetic method for treating hair with the aid of an assembly comprising:
a straightening iron to be moved along a lock of hair comprising:
a bottom jaw and an upper jaw connected together by a hinge, the bottom jaw and the upper jaw being 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 jaws, and
at least one heating element disposed on one of the jaws and intended to come into contact with the hair while the jaws are in the moved-together configuration, and

a collecting device coupled to the bottom jaw of the straightening iron, the collecting device having a reservoir, the collecting device comprising a fastening system to couple the collecting device to the bottom jaw, the reservoir extending along the straightening iron and laterally on the side of the bottom jaw, the method comprising:
applying water in a liquid form and/or a cosmetic composition in a liquid or foam form to the hair,
passing the straightening iron over the hair, and
collecting, with the aid of the collecting device, a runoff of liquid or foam in the reservoir due to the presence of water and/or the cosmetic composition on the hair and the passage of the straightening iron.

14. Method for treating hair according to claim 13 , wherein the application of the water and/or the cosmetic composition to the hair is carried out independently of the passage of the straightening iron over the hair.

15. Method for treating hair according to claim 13 , wherein:
the water is applied to the hair during the application step and/or
the cosmetic composition is applied to the hair during the application step, and the passage of the heating element along the hair brings about the runoff resulting from the melting of a compound of the cosmetic composition previously applied to the hair.

16. Method for treating hair according to claim 13 , wherein the collecting device is fastened in a removable manner to the straightening iron.

17. Method for treating hair according to claim 13 , wherein the collecting device is fastened in a permanent manner to the straightening iron.

18. Method for treating hair according to claim 13 , wherein the collecting device is disposed downstream of the heating element with regard to a direction of movement of the straightening iron over the lock of hair.
