## Title
Powder cosmetic brush

## Abstract

Provided is a cosmetic brush. The cosmetic brush includes a cylindrical bottle, a body, a hair holder, a filter, a sleeve, and a cap. When makeup is applied, the sleeve descends. When the sleeve is stored, the sleeve ascends to easily close the cap. When the sleeve descends, a powder is supplied toward hairs. When the sleeve ascends (is stored), the supply of the powder is intercepted to prevent the powder from being unnecessarily discharged, thereby preventing other portable products from being damaged. Also, when the sleeve is stored, the sleeve blocks the powder discharge hole to prevent the powder remaining within the discharge hole from being hardened by moisture, thereby smoothly discharging the powder.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
Korean patent application KR 10-2011-0119030, filed Nov. 15, 2011, is incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to a powder cosmetic brush, and more particularly, to a powder cosmetic brush having a structure in which a sleeve for gathering hairs when a cap is closed is forwardly or reversely rotated together with a hair holder to maintain a powder discharge hole in an open state, thereby discharging powder from a bottle, or to maintain the powder discharge hole in a close state, thereby prevent the powder from being discharged.
DESCRIPTION OF THE RELATED ART
In general, cosmetics are classified into solid cosmetics and liquid cosmetics in which liquid cosmetics are adequately mixed. Recently, for user's convenience, cosmetics such as lipstick or foundation are being supplied in liquid type. That is, liquid cosmetics may be filled into a container having an approximate pencil shape. Then, when the cosmetics are used, a portion of the container may be rotated to discharge the cosmetics within the container into an upper portion of a cosmetic brush to make up.
In conventional cosmetic brushes used commonly, a brush is integrated with a body to use a brush coated with separate powder when makeup is applied. Since the powder and the brush are separately provided, it may be inconvenient to carry and store the powder and the brush. Accordingly, it is not easy to utilize the cosmetics.
Recently, various cosmetic brushes having a structure in which powder is received into a body having a container shape to discharge the powder received in the body toward a brush, thereby applying makeup are being proposed and used. This is disclosed in Korean Utility Model registration No. 0253672.
A conventional powder cosmetic brush includes a first body having a tube shape with upper and lower side opened, the first body receiving powder therein, a second body coupled to a lower outer surface of the first body and having a discharge hole in a central portion of a top surface thereof, the second body including a brush connected to the discharge hole on a front end thereof; a vertical transfer shaft coupled to a spring on an outer surface of a front end thereof, wherein the front end is coupled to the discharge hole of the second body and the spring is supported by an outer circumference of an upper end of the discharge hole, and an upper cap coupled to an upper end of the first body to allow the vertical transfer shaft to protrude to the upper outside, the upper cap supporting the vertical transfer shaft.
However, in the conventional powder cosmetic brush, the powder is discharged by the front end of the vertical transfer shaft. However, it may be inconvenient to constantly discharge the powder due to a structure of the vertical transfer shaft as well as to discharge the powder toward the brush due to shaking of the cosmetic brush itself.
Also, the conventional powder cosmetic brush has a structure in which a button disposed on the upper cap continuously protrudes outward by elasticity of the spring. Thus, when the powder cosmetic brush collides with other portable products during the carrying and storage or an external force is applied to the powder cosmetic brush, the button may be moved to unnecessarily discharge the powder to the brush, thereby damaging the other portable products. Also, when the powder cosmetic brush is stored in a wet state or is not used for a long time, the powder within the first body and the powder remaining within the discharge hole may be hardened by the moisture. Thus, it may be difficult to smoothly discharge the powder hardened by moisture.
Also, a cosmetic brush disclosed in U.S. Pat. No. 6,935,802 has a complicated structure in which a sleeve type protection cap is movably disposed on an inner operation body and an operation body is disposed on a lower portion of the sleeve type protection cap.
According to the conventional cosmetic brush, there are limitations that a structure for opening or closing the discharge hole for the powder is complicated and manufacturing costs are high.
SUMMARY OF THE INVENTION

Here, the powder discharge holes 123 and the communication holes 131 are opened to supply the powder within the bottle 110 into the hairs H (see FIG. 9).
In the state when the sleeve 150 descends, the dropping down prevention projection 151 is hooked on the dropping down prevention projection 151 to fix the sleeve 150 in position.
The powder discharge holes 123 and the communication holes 131 are opened to supply the powder within the bottle 110, thereby applying makeup in the state where the sleeve 150 is fixed in position.
As described above, the hair holder may be rotated by rotating the sleeve. Here, the powder discharge hole and the communication hole may be maintained in the open state to discharge the powder within the bottle. On the other hand, the powder discharge hole and the communication hole may be maintained in the close state to prevent the powder within the bottle from being discharged. Also, the powder may be discharged or not discharged by using the sleeve. Therefore, the close/open structure may be simplified to significantly reduce the mold manufacturing costs.
As described above, the hair holder may be rotated by rotating the sleeve. Here, the powder discharge hole and the communication hole may be maintained in the open state to discharge the powder within the bottle. On the other hand, the powder discharge hole and the communication hole may be maintained in the close state to prevent the powder within the bottle from being discharged. Also, the powder may be discharged or not discharged by using the sleeve. Therefore, the close/open structure may be simplified to significantly reduce the mold manufacturing costs.
