Refill for a device for the treatment of the hair

Abstract

A refill for a device for treating hair, including: a reservoir of elongate shape along a longitudinal axis, defining a cavity containing a cosmetic composition to be applied to the hair, the reservoir having a flank for mounting the refill on the device, extending parallel to the longitudinal axis of the reservoir, a porous application member for applying the cosmetic composition to the hair, of elongate shape and extending parallel to the longitudinal axis of the reservoir. The application member being fitted in a slot-shaped opening in the reservoir that leads into the cavity, this opening being offset laterally toward the mounting flank, relative to a median plane of the cavity that contains the longitudinal axis of the reservoir and is parallel to the mounting flank.

         20 . A refill for a device for treating the hair, having:
 a reservoir of elongate shape along a longitudinal axis, defining a cavity containing a cosmetic composition to be applied to the hair, the reservoir having a flank for mounting the refill on the device, extending parallel to the longitudinal axis of the reservoir,   a porous application member for applying the cosmetic composition to the hair, of elongate shape and extending parallel to the longitudinal axis of the reservoir, the application member being fitted in a slot-shaped opening in the reservoir that leads into the cavity, this opening being offset laterally toward the mounting flank, relative to a median plane of the cavity that contains the longitudinal axis of the reservoir and is parallel to the mounting flank.   
     
     
         21 . The refill as claimed in  claim 20 , wherein the mounting flank bears a profile for fastening to the treatment device, extending along the reservoir, the fastening profile being configured to be fastened to an insertion guide of the device, the opening opening toward the outside between the longitudinal axis of the reservoir and the fastening profile. 
     
     
         22 . The refill as claimed in  claim 20 , wherein the cavity is cylindrical. 
     
     
         23 . The refill as claimed in  claim 20 , wherein the opening has a constant width along its length and over its height. 
     
     
         24 . The refill as claimed in  claim 20 , wherein the application member extends through the opening into the cavity over at least a part of its height. 
     
     
         25 . The refill as claimed in  claim 20 , wherein the opening has, in cross section through the refill, a median plane parallel to said median plane of the cavity and spaced apart from said median plane of the cavity by a nonzero distance d. 
     
     
         26 . The refill as claimed in  claim 25 , wherein distance d between the median plane of the opening in cross section through the refill and the median plane of the cavity is constant along the longitudinal axis of the reservoir, and corresponds to a fraction of between 30 and 100% of the distance K between the longitudinal axis of the reservoir and the lateral wall of the cavity, measured perpendicularly to the median plane of the cavity. 
     
     
         27 . The refill as claimed in  claim 20 , wherein the application member is in abutment against a wall of the reservoir. 
     
     
         28 . The refill as claimed in  claim 20 , wherein the application member has an application portion extending at least partially outside the opening and the cavity and a remaining portion extending through the opening in the reservoir and into the cavity, the application portion being thicker than the portion, 
     
     
         29 . The refill as claimed in  claim 28 , wherein the application member has a shoulder between the application portion and the portion, which comes into abutment against a wall of the reservoir. 
     
     
         30 . The refill as claimed in  claim 20 , wherein the application member is made of felt. 
     
     
         31 . The refill as claimed in  claim 20 , which has a removable cover configured to cover the application member. 
     
     
         32 . A device for the heat treatment of the hair, straightening the hair, having:
 two arms that are movable 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, the two movable arms defining a treatment surface between one another in the moved-together configuration,   a refill as claimed in  claim 20 , which is mounted in a removable manner on one of the two arms.   
     
     
         33 . The device as claimed in  claim 32 , which has a heating element that is intended to come into contact with the hair and defines, with the opposite arm facing it, the treatment surface, 
     
     
         34 . The device as claimed in  claim 33 , wherein the device has two heating elements that are intended to come into contact with the hair and are each disposed on an arm, defining the treatment surface between one another. 
     
     
         35 . The device as claimed in  claim 32 , wherein one of the arms has a steam outlet, 
     
     
         36 . The device as claimed in  claim 35 , wherein the steam outlet is disposed between the treatment surface defined by the heating element(s) intended to come into contact with the hair and the application member of the refill. 
     
     
         37 . The device as claimed in  claim 32 , wherein the application member is at a distance v from the steam outlet, measured between the median plane of the opening and the median plane of the steam outlet, of less than or equal to 10 mm. 
     
     
         38 . The device as claimed in  claim 32 , which has a pressing element, facing the application member, that is configured to press the hair against the application member in the moved-together configuration of the arms. 
     
     
         39 . The device as claimed in  claim 37 , wherein the pressing element is mounted on a spring configured to press the hair against the application member with a constant force.
