Device for treating the hair

Abstract

Device for treating the hair having two hair treatment jaws that are movable relative to one another between a spaced-apart configuration and a moved-together configuration, an internal treatment member having an internal surface for heating the hair to be treated, which extends over one of the two jaws towards the other in the moved-together configuration of the two jaws and is configured to come into contact with the hair extending between the two jaws in the moved-together configuration thereof, an external treatment member having an external surface for heating the hair to be treated, which extends over one of the jaws towards the exterior of the jaws, one of the jaws having a lateral recess along at least a part of the jaw, the lateral recess facing at least a part of the other jaw and being delimited at least in a proximal and/or distal part of the jaw by a guiding surface.

1 . A device for treating the hair, comprising:
 two hair treatment jaws that are movable relative to one another between a spaced-apart configuration for inserting hair to be treated between said jaws and a moved-together configuration for treating the hair,   an internal treatment member having an internal surface for heating the hair to be treated, which extends over one of the two jaws towards the other of the jaws in the moved-together configuration of the two jaws and is configured to come into contact with the hair extending between the two jaws in the moved-together configuration thereof,   an external treatment member having an external surface for heating the hair to be treated, which extends over at least one of the two jaws towards the exterior of the jaws,   
       one of the jaws having a lateral recess along at least a part of the jaw, the lateral recess facing at least a part of the other jaw and being delimited at least in a proximal and/or distal part of the jaws by a guiding surface affording a sufficient obstacle to contain the hair to be treated within the lateral recess. 
     
     
         2 . The device according to  claim 1 , wherein the or each guiding surface has a variable height He. 
     
     
         3 . The device according to  claim 1 , wherein the jaw having the lateral recess has a width  1   1  measured, at the lateral recess, parallel to the median plane of the device defined by the internal treatment surface in the moved-together configuration of the jaws, that is less than or equal to the width  1   2  of the other jaw. 
     
     
         4 . The device according to  claim 1 , wherein the or each external treatment member has an external plate extending over the external surface of the corresponding jaw, having a shape substantially complementary to the latter, the or each external plate having an external contact surface for contact with the hair at least partially defining the external heating surface. 
     
     
         5 . The according to  claim 1 , having two internal treatment members that each extend over one of the jaws and each have at least one internal heating surface, the internal heating surfaces; facing one another and being configured to grip the hair between one another in the moved-together configuration of the jaws. 
     
     
         6 . The device according to  claim 1 , having two external treatment members that each extend over one of the jaws and each have at least one external hair heating surface extending over the respective jaws towards the exterior of the device, being on opposite sides to one another on the device in the moved-together configuration of the jaws. 
     
     
         7 . The device according to  claim 1 , wherein at least one jaw has an external hair guiding portion delimited laterally in the proximal and/or distal part of the jaw, better still in the proximal and distal part of the jaw, by a stop surface, the or each external heating surfaces extending, at least partially, in the external guiding portion of the corresponding jaw. 
     
     
         8 . The device according to  claim 7 , wherein the lateral recess extends in the guiding portion of the corresponding jaw, the guiding surface or surfaces; being formed by the stop surface or surfaces of the guiding portion, the stop surface or surfaces of the jaw that has a lateral recess preferably having a continuously variably height He. 
     
     
         9 . The device according to  claim 1 , having an additional hair treatment member that extends from one of the two jaws towards the other jaw in the moved-together configuration of the two jaws and is arranged on said jaw laterally in the moved-together configuration of the jaws with respect to the internal treatment member. 
     
     
         10 . The device according to  claim 9 , wherein the additional treatment member may have at least one steam outlet and/or a cosmetic product applicator member and/or a member that exerts a pulling force on the hair. 
     
     
         11 . The device according to  claim 9 , the additional treatment member extending over and from the jaw that does not have the lateral recess in the direction of the other jaw and having a comb at least partially facing the lateral recess and the moved-together configuration of the jaws, extending towards the other jaw and being accommodated at least partially in the lateral recess, and one or more steam outlets facing a part of the jaw bearing the lateral recess, the steam outlet or outlets extending between the comb and the internal hair heating surface or surfaces. 
     
     
         12 . The device according to  claim 11 , wherein the comb is arranged on the corresponding jaw such that the distal end of its teeth is spaced apart by a non-zero distance Dd from hair wound under tension around the two jaws in the moved-together configuration of the jaws. 
     
     
         13 . A method for treating the hair with the aid of the device according to  claim 1 , involving the insertion of a lock of hair between the two jaws and/or against at least a part of the external heating surface of the device and the movement of the device along the lock of hair from the root to the tip thereof.
