This application claims the benefit of Korean Application No. 10-2015-0184963 filed on Dec. 23, 2015 with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
The present invention relates to a brush and a manufacturing method thereof and, more particularly, to a brush that is manufactured by mechanically pressing it and a manufacturing method thereof.
Make-up for put on makeup is generally provided in a liquid state, a solid state, and a mixed state of liquid and solid. Brushes having various shapes and sizes have been developed and used to apply solid-state make-up to a face.
That is, those brushes enable a user to put make-up that is in a solid powder state on the brushes and then appropriately apply the make-up to a face. Those brushes are composed of a hand that a user can hold with a hand and a plurality of hairs at an end of the handle.
The hairs have been attached to a handle by chemical substances such as an adhesive in the related art. In this case, since the adhesive is a chemical substance and may have a harmful influence on a human body, so using an adhesive that is not harmful to a human body in consideration of this problem increases the manufacturing cost.
Further, since adhesives are vulnerable to heat, when they are exposed to heat, the adhered portion is separated and durability is decreased.
The technical configuration described above is the background for helping understand the present invention, but does not mean the related art that is widely known in the field of the present invention.
Korean Utility Model No. 20-0255125 (Jang-Seong Park), Publication Date: 2001.12.13.
Accordingly, an object of the present invention is to provide a brush that can remove the defects due to using an adhesive by mechanically pressing the brush, and a manufacturing method thereof.

The brush hairs may not be disposed at the outermost edge of the brush coupler and top of the coupling member may be bent and locked to the outermost edge.
The fixing member may include a packing.
The brush body may be made of wood.
The brush body may be made of metal and a pressing groove may be formed at the portion, where the coupling member is pressed, on the brush body.

In this state, the pressing head 233 is moved toward the front side of the main body 100 by operating the brush-fitting unit 200. As illustrated in
Thereafter, the pressing head 233 is returned to the initial position and then the brush-rotating unit 400 is operated, whereby the brush holder 360 is rotated at a predetermine angle, about 20 degrees. The pressing head 233 is moved again to surround the pressing body 210, thereby pressing the coupling member 30 with the plurality of pressing projections 220. Accordingly, sequential grooves are formed on the coupling member 30, as illustrated in
Finally, the finished brush 1 is returned to the brush-feeding unit 300 after the pressing head 233 is returned to the initial position, and then the brush 1 is released from the pair of holder tongs 363.
As described above, according to the embodiment, a coupling member and a brush body are combined by pressing the portion of the coupling member where the coupling member and the brush body are in contact with each other, so they can be combined without an adhesive and it is possible to preclude harmful substances of an adhesive.
Further, a fixing member is provided between a brush hair part and a coupling member, so it is possible to prevent shaking of the brush hair part before coupling the brush body.
