MAKEUP BRUSH

[0001] The present disclosure relates to a makeup brush and, more particularly, to a makeup brush that allows a complete product to be assembled without using an adhesive during the manufacturing process of the brush and enables convenient mounting of bristles.

[0002] In general, cosmetics that are used for makeup are in the form of a liquid, a solid, or a mixture of liquid and solid. Brushes having various shapes or sizes have been developed and used to apply solid-type cosmetics to the face.

[0003] That is, such brushes are configured to allow solid powder-type cosmetics to be applied appropriately to the face or the like by being picked up on the bristles of the brushes. Such brushes include a handle that can be held by a user and a brush head that is provided at a front end of the handle and composed of a plurality of bristles.

[0004] Previously, the brush head was bonded to the handle using chemicals such as adhesives. In this case, since adhesives are made of chemicals, they may have harmful effects on the human body, and considering this, if adhesives harmless to the human body are used, there is a problem that manufacturing costs increase.

[0005] Further, since adhesives are materials vulnerable to heat, when they are exposed to heat, there is a problem that the bonded part separates and the durability decreases. The above description is the background for helping understand the present disclosure and does not means the related art well known in the art.
