Abstract

The present invention relates to a cosmetic refill (20) intended to be inserted in a removable manner into a housing in a system (2) for treating the hair, comprising: —a hair product reservoir comprising an opening, —a porous application member (26) extending partially into the reservoir through the opening, the application member (26) being fixed in the reservoir when the refill (20) is used.

1 : A cosmetic refill intended to be inserted in a removable manner into a housing of a system for treating the hair, comprising:
 a hair product reservoir that has an opening,   a porous application member extending partially into the reservoir through the opening, the application member being fixed in the reservoir when the refill is used.   
     
     
         2 : The refill as claimed in  claim 1 , the application member extending into the reservoir over the entire height H of the latter, advantageously bearing on the bottom of the reservoir. 
     
     
         3 : The refill as claimed in  claim 1 , the application member having at least two opposite sides extending at least partially into the reservoir and at least partially in contact with the hair product contained in the reservoir. 
     
     
         4 : The refill as claimed in  claim 1 , the application member being made from a sintered material. 
     
     
         5 : The refill as claimed in  claim 1 , the application member being molded. 
     
     
         6 : The refill as claimed in  claim 1 , the application member having a cross section greater than or equal to that of the opening. 
     
     
         7 : The refill as claimed in  claim 1 , the application member being mounted in a removable manner in the reservoir. 
     
     
         8 : The refill as claimed in  claim 1 , the thickness of the application member being less than or equal to 30 mm. 
     
     
         9 : The refill as claimed in  claim 1 , the reservoir being of substantially cylindrical form. 
     
     
         10 : The refill as claimed in  claim 1 , the reservoir comprising a hair product filling aperture closed by a removeable stopper.

         13 : The method as claimed in  claim 12 , the amount of hair product deposited in one application, exerting a pressure of 34 N and moving the applicator at a speed of 2 cm/s over a standard 80 g/m 2  sheet of paper 27 cm long, being between 0.005 g and 0.5 g. 
     
     
         14 : The method as claimed in  claim 12 , the amount of hair product deposited with the refill in one application, exerting a pressure of 34 N and moving the applicator at a speed of 2 cm/s over a standard 80 g/m 2  sheet of paper 27 cm long, varying by up to 50% from the amount of product deposited between the first and the 75th applications.
