  • In color cosmetics, auxiliary instruments such as mirrors and cosmetic brushes are required, and even in the case of the cosmetic brushes, various types of brushes, such as a lip brush, a blender brush, an eye shadow brush, a mascara brush, a cheek brush are used according to a use purpose.
  • The above-described brushes are provided so that the cosmetics made of solid powder may be coated on bristles of the brush to be properly applied on the face and the like. Such a brush may be constituted by a handle which may be held by a user and a brush provided at the front end of the handle and formed of a plurality of bristles.
  • In the related art, the brush is coupled to the handle by using chemical materials such as a glue. In this case, the glue may be formed of a chemical material, which may harmful affect the human body, and considering this, when a glue harmless to the human body is used, there is a problem that the manufacturing cost increases.
  • In addition, since the glue is a material that is vulnerable to heat, there is a problem that when the glue is exposed to heat, a glue portion is detached so that the durability deteriorates.
  • The above-described technical configuration is the background art for helping in the understanding of the present invention, and does not mean a conventional technology widely known in the art to which the present invention pertains.
    • SUMMARY OF THE INVENTION
  • Therefore, the present invention has been made in an effort to provide a no-glue cosmetic brush and its manufacturing method capable of being manufactured without using a glue and manufactured using a shorter brush hair than the related art.

  • The fusion portion may be provided with a diameter smaller than an upper portion of the brush hair and provided by thermal fusion.
  • The fusion portion may be 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.
  • According to another aspect of the present invention, there is provided a no-glue cosmetic brush manufactured by the aforementioned method, as a cosmetic brush.
  • According to the embodiments of the present invention, the fusion portion is provided by applying heat to the lower end of the shaped brush hair and inserted to the hair fixing tube and then the hair fixing tube is pressed, thereby manufacturing the brush without using a glue.
  • Further, according to the aforementioned method, the brush may be manufactured by using a shorter brush hair than the related art without using a glue, thereby reducing the brush hair.
