Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims the benefit of priority to Korean Patent Application No. 10-2018-0102637 filed on Aug. 30, 2018, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a cosmetic brush and a manufacturing method thereof, and more particularly, to an improved cosmetic brush used for applying a cosmetic to a face and a manufacturing method thereof.

Description of the Related Art

In general, cosmetics used for make-up are 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.
In color cosmetics, auxiliary instruments such as mirrors and cosmetic brushes are required, and in the case of the cosmetic brushes, various kinds of brushes such as a lip brush, a blender brush, an eye shadow brush, a mascara brush, a cheek brush are used.
The above-described brush is 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 made of a plurality of bristles.
Previously, the brush is coupled to the handle using chemical materials such as adhesives. In this case, the adhesive may be formed of a chemical material, which may adversely affect the human body, and in view of this, there is a problem in that the manufacturing cost increases when an adhesive harmless to the human body is used.
Since the adhesive is a material that is vulnerable to heat, there is a problem in that when the adhesive is exposed to heat, the adhesive portion is detached and thus durability deteriorates.
The above-described technical configuration is a background technique for assisting the understanding of the present invention, and does not mean a conventional technology widely known in the art to which the present invention belongs.

SUMMARY OF THE INVENTION

Therefore, an object of the present invention is to provide an improved cosmetic brush and a manufacturing method thereof capable of being manufactured without using an adhesive and stably maintaining a bonded structure.
According to an aspect of the present invention, there is provided an improved cosmetic brush including: a brush bristle coupling portion of which brush bristles are coupled to one side portion; a connection fixing portion of which the brush bristle coupling portion is coupled to the inside; and a handle portion of which the brush bristle coupling portion and the connection fixing portion are coupled to one side portion, in which the handle portion includes a handle body, a first step body provided to be stepped on an end portion of the handle body and press-coupled with an end portion of the connection fixing portion, and a second step body provided to be stepped on an end portion of the first step body and press-coupled with end portions of the connection fixing portion and the brush bristle coupling portion.
The connection fixing portion may include a connection fixing body in which one side portion is coupled to the first step body and the second step body and the brush bristle coupling portion is accommodated therein, and the connection fixing body may include: a first pressing region provided to press the connection fixing body of a region corresponding to the region of the first step body; and a second pressing region provided to press the connection fixing body and the brush bristle coupling portion of a region corresponding to the region of the second step body.
The brush bristle coupling portion may include: a fixing body in which one side portion is inserted and coupled to the second step body and the second press region is provided; a curved body extending to the other side portion of the fixing body and fixing the brush bristles to the inside; and an end body provided at an end portion of the curved body to hold the brush bristles.
According to another aspect of the present invention, there is provided a manufacturing method for an improved cosmetic brush including: pressing one side portion of a brush bristle coupling portion to couple brush bristles to the inside of the brush bristle coupling portion; inserting the brush bristle coupling portion coupled with the brush bristles into a connection fixing portion; fitting the brush bristle connection portion and the connection fixing portion so as to fit one side portion of the connection fixing portion to a first step body of a handle portion and fit one side portion of the brush bristle coupling portion to a second step body of the handle portion, wherein the handle portion includes the handle body, the first step body provided to be stepped on the end portion of the handle body, and the second step body provided to be stepped on the end portion of the first step body; and providing a first pressing region by pressing the connection fixing portion of a region corresponding to the region of the first step body and providing a second pressing region by pressing the connection fixing portion and the brush bristle coupling portion of a region corresponding to the region of the second step body.
According to the exemplary embodiments of the present invention, a brush bristle bonding portion, a connection fixing portion, and a handle portion are coupled to each other without using an adhesive, thereby fundamentally preventing harmful components of the adhesive.
Further, the handle portion is provided with a handle body, a first step body and a second step body, the end portion of the connection fixing portion is press-coupled to the first step body, and the end portion of the connection fixing portion and the end portion of the brush bristle bonding portion is press-coupled to the first step body, thereby stably maintaining a coupled structure.
