No-glue cosmetic brush and its manufacturing method

Abstract

Disclosed are a no-glue cosmetic brush and its manufacturing method. The manufacturing method of the no-glue cosmetic brush of the present invention includes the steps of forming a shape of a brush hair by using a plurality of hair members; providing a fusion portion by applying heat to a lower end of the shaped brush hair; processing the brush hair in a desired shape by pressing a hair fixing tube in a region to which the fusion portion is inserted; and coupling the brush hair to the hair fixing tube by pressing the hair fixing tube after inserting the brush hair to the hair fixing tube.

What is claimed is: 
     
         1 . A manufacturing method of a no-glue cosmetic brush comprising the steps of:
 forming a shape of a brush hair by using a plurality of hair members;   providing a fusion portion by applying heat to a lower end of the shaped brush hair;   processing the brush hair in a desired shape by pressing a hair fixing tube in a region to which the fusion portion is inserted; and   coupling the brush hair to the hair fixing tube by pressing the hair fixing tube after inserting the brush hair to the hair fixing tube.   
     
     
         2 . The manufacturing method of the no-glue cosmetic brush of  claim 1 , wherein the fusion portion is provided with a diameter smaller than the upper portion of the brush hair and provided by thermal fusion. 
     
     
         3 . The manufacturing method of the no-glue cosmetic brush of  claim 1 , wherein the fusion portion is disposed at a position of the shaped hair fixing tube when coupling the brush hair to the hair fixing tube so as not to require the fixing of the position of the brush hair. 
     
     
         4 . A no-glue cosmetic brush manufactured by the method of  claim 1 . 
     
     
         5 . A no-glue cosmetic brush manufactured by the method of  claim 2 .
