Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority of Korean Patent Application No. 10-2021-0109657 filed on Aug. 19, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

The present disclosure relates to a cosmetic brush and, more particularly, to a cosmetic brush that can be assembled into a complete product without using an adhesive in the process of manufacturing the brush and of which components can be conveniently replaced.

Description of the Related Art

In general, cosmetics that are used for makeup are usually liquid, solid, and a mixture of liquid and solid. Brushes having various shapes or sizes have been developed and used to put solid-state cosmetics on the face.

That is, such brushes are configured to put a cosmetic made of a solid powder on the hairs thereof and appropriately apply the cosmetic on a face, etc. Such brushes are composed of a grip that a user can hold with a hand and a brush part made of a plurality of hairs and formed at the end of the grip.

In the related art, a brush part was attached to the grip using chemical substances such as an adhesive. In this case, there is a problem that since adhesives may have a harmful influence on human body because they are made of chemical substances, and the manufacturing cost increases when adhesives that are not harmful to human body are used.

Further, since adhesives are substances that are vulnerable to heat, there is a problem that when they are exposed to heat, the bonded portion is separated and 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.
