Abstract: A cosmetic brush having a stem and a brush part is disclosed. The brush part, comprising bristles formed through injection molding, is provided on an end of the stem. The brush part includes a base for coupling the brush part to the stem, and the bristles which are integrated with the base through injection molding have a fine thickness. Each of the bristles is formed through injection molding to have thickness ranging from 0.05 mm to 0.15 mm. The brush part is manufactured through injection molding, thus enabling the use of various materials and affording various designs, therefore improving the competitiveness of a product. Further, structure and manufacturing process are simplified, so that manufacturing and equipment costs are reduced.

Abstract: The present invention provides a mascara brush, which is manufactured through a double injection molding process, thus reducing production costs and enhancing workability and productivity. The mascara brush of the present invention includes a bristle part (120), for applying mascara to eyelashes, and a comb part (130) for tidying the eyelashes. The bristle part has a cylindrical brush body (110) and bristles (121), which are formed around the brush body through an injection molding process. The comb part is formed such that part of the comb part is embedded in the brush body. The bristle part and the comb part are formed through double injection molding. Furthermore, each bristle may have branches to thus have a snowflake shape, thus increasing its ability to absorb mascara.

Abstract: A mascara brush is disclosed. The mascara brush of the present invention includes a bristle part (120) for applying mascara to eyelashes, and a comb part (130) for tidying the eyelashes. The bristle part and the comb part are integrally formed with a brush body through an injection molding process, such that the bristles of the bristle part are thin and the comb teeth of the comb part are relatively thick. As such, in the present invention, because the bristle part, for applying mascara to the eyelashes, and a comb part, for tidying the eyelashes, are integrally formed with the brush body by injection molding, manufacturing equipment and manufacturing and assembling processes can be simplified, thus reducing production costs and enhancing workability and productivity.
