[0001] Reference to the related application

[0002] This application claims priority from Korean patent application No. 10-2021-0109657 filed on August 19, 2021 with the Korean Intellectual Property Office.

[0003] CONTEXT OF THE INVENTION Scope of the invention

[0004] This disclosure relates to a cosmetic brush and, more particularly, a cosmetic brush that can be assembled into a complete product without using adhesive in the brush manufacturing process and whose components can be easily replaced.

[0005] Description of the prior art:

[0006] In general, cosmetics used for makeup are usually liquids, solids, and a mixture of liquids and solids. Brushes of different shapes or sizes have been developed and used to apply solid cosmetics to the face.

[0007] In other words, these brushes are configured to deposit a cosmetic product consisting of a solid powder onto their bristles and to apply the cosmetic product appropriately to a face, etc. These brushes consist of a handle that a user can hold with their hand and a brush part consisting of a plurality of bristles and formed at the end of the handle.

[0008] In related art, a part of the brush was attached to the handle using chemical substances such as an adhesive. The problem in this case is that adhesives can have a harmful effect on the human body because they are made of chemical substances, and that the manufacturing cost increases when adhesives that are not harmful to the human body are used.

[0009] Moreover, since adhesives are substances vulnerable to heat, the problem is that when they are exposed to heat, the glued part separates and the durability decreases.

[0010] The above description is the context to help understand this disclosure.
