Field of the Invention

The present invention relates to a cosmetic brush and more particularly, to a cosmetic brush capable of assembling a complete product without using an adhesive in a process of manufacturing a brush.

Description of the Related Art

In general, cosmetics used for make-up are formed in a liquid, a solid, and a mixed state of the liquid and the solid. Among them, in order to apply the solid cosmetics on the face, brushes having various shapes and sizes have been developed and used.
That is, 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 an adhesive. In this case, the adhesive may be formed of a chemical material, which may have a harmful effect on the human body, and considering this, in the case of using an adhesive harmless to the human body, there is a problem that the manufacturing cost increases.
In addition, since the adhesive is a material that is vulnerable to heat, there is a problem that when the adhesive is exposed to heat, an adhesive 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.
According to an aspect of the present invention, there is provided a cosmetic brush which includes a brush body provided as a handle of a user, a brush coupling part coupled to the brush body, and a brush bristle part detachably coupled to the brush coupling part and provided with bristle members, wherein the brush coupling part includes a first coupling portion and a second coupling portion which are detachably coupled to each other, the brush coupling part is detachably coupled to the brush body while the first coupling portion and the second coupling portion are coupled to each other, and the brush bristle part is detachably coupled to the brush coupling part.
The first coupling portion may include a first body which covers one side of a lower portion of the brush bristle part, and a first insertion body which is provided at a lower portion of the first body and coupled to one side of an upper end of the brush body, wherein a first flange coupling groove coupled with one side portion of the flange member of the brush bristle part may be provided on an inner wall of the first body.
The second coupling portion may include a second body which covers the other side of the lower portion of the brush bristle part, and a second insertion body which is provided at a lower portion of the second body and coupled to the other side of the upper end of the brush body, wherein a second flange coupling groove coupled with the other side portion of the flange member of the brush bristle part may be provided on an inner wall of the second body.
In the first body, at least one first coupling groove and at least one first coupling protrusion may be provided, and in the second body, at least one second coupling protrusion coupled to the first coupling groove and at least one second coupling groove coupled with the first coupling protrusion may be provided.
The first body and the second body may be screwed to the brush body.
According to the embodiments of the present invention, the brush coupling part includes a first coupling portion and a second coupling portion detachably coupled to each other, the brush coupling part is detachably coupled to the brush body while the first coupling portion and the second coupling portion are coupled to each other, and the brush bristle part is detachably coupled to the brush coupling part to be assembled without an adhesive, thereby fundamentally preventing a harmful component of an adhesive.
Further, the brush bristle part is detachably screwed to the brush coupling part, thereby easily replacing the brush bristle part.
