Abstract

A cosmetic brush is provided to carry a cosmetic powder therein to, protect the brush from the contamination or the wear-down, and prevent the discharge of the powder while the brush is not in use. The cosmetic brush comprises a cylinder containing the cosmetic powder and having discharge holes on one end; a connect cap being coupled with the cylinder and guiding the discharge of the cosmetic powder through the discharge holes; a pressure pump being screw-coupled with the cylinder to make the cosmetic powder move into the brush by its pumping; a guide tube being coupled with the cylinder, the brush moving therein; a sliding tube having the brush inserted therein and being free to rotate with fitting into the guide tube; a discharge pipe being placed into the brush to uniformly supply the cosmetic powder; and a covering cap for detachably covering the sliding tube to protect the brush.

Claims

1. A cosmetic brush comprising:

a cylinder, a first end of which is open to contain cosmetic powder, and a second end of which has discharge holes to discharge the cosmetic powder and is coupled with a connect cap to open/close the discharge holes and to guide the discharge of the cosmetic powder;

a pressure pump being screw-coupled with said first end of the cylinder, and injecting air to discharge the cosmetic powder in the cylinder into a brush having an external end and two or more guide protrusions;

a guide tube being coupled with the cylinder at a first end of said guide tube, and having two or more guide grooves in a spiral on its inner surface to guide movement of said guide protrusions of the brush;

a sliding tube having a slide aperture longitudinally formed in a surface of a first part of said sliding tube for receiving the brush inserted therein, the slide aperture being coupled with the guide protrusions of the brush, and the sliding tube being free to rotate with fitting into the guide tube; and

a covering cap detachably coupled with a second part of the sliding tube for covering and protecting the brush.

2. The cosmetic brush according to the claim 1, wherein one or more guide protrusions are formed on an outer circumferential surface of the cylinder having the discharge holes, and one or more guide grooves are formed on an inner circumferential surface of the connect cap, the guide protrusion and the guide groove being rotatably coupled with each other by force fitting.

3. The cosmetic brush according to the claim 1, wherein a discharge pipe is formed on the connect cap extended from one surface of the connect cap, the discharge pipe is aligned with at least on of the discharge holes on said second end of the cylinder and being inserted into the brush.

4. The cosmetic brush according to the claim 3, wherein the discharge pipe is formed to have a length to reach inside the brush to apply the cosmetic powder uniformly on a skin portion of a user when a user is using the brush, and to move forwardly to an external end of the brush when the brush is out of use and kept in.

5. The cosmetic brush according to the claim 1, wherein a packing is interiorly formed on an inner surface of the connect cap to surround said discharge holes of the cylinder.

6. The cosmetic brush according to the claim 1, wherein the guide tube and the sliding tube are rotatably coupled with each other by force fitting.

7. The cosmetic brush according to the claim 1, wherein a fixing stop is formed on both ends of the slide aperture of the sliding tube, respectively and coupled with the guide protrusion of the brush to prevent the further sliding movement of the brush by a longitudinally applied force on the brush or the sliding tube.

8. A cosmetic brush comprising:

first means, a first end of which is open to contain cosmetic powder, and a second end of which has discharge holes to discharge the cosmetic powder and is coupled with a connect cap to open/close the discharge holes and to guide the discharge of the cosmetic powder;

pump means being screw-coupled with said first end of said first means, and injecting air to discharge the cosmetic powder in said first means into a brush having an external end and two or more guide protrusions;

guide means being coupled with said first means at a first end of said guide means, and having two or more guide grooves in a spiral on its inner surface to guide movement of said guide protrusions of the brush;

sliding means having a slide aperture longitudinally formed in a surface of a first part of said sliding means for receiving the brush inserted therein, the slide aperture being coupled with the guide protrusions of the brush, and said sliding means being free to rotate with fitting into said guide means; and

covering means detachably coupled with a second part of said sliding means for covering and protecting the brush.

9. The cosmetic brush according to the claim 8, wherein one or more guide protrusions are formed on an outer circumferential surface of the first means having the discharge holes, and one or more guide grooves are formed on an inner circumferential surface of the connect cap, the guide protrusion and the guide groove being rotatably coupled with each other by force fitting.

10. The cosmetic brush according to the claim 8, wherein a discharge pipe is formed on the connect cap extended from one surface of the connect cap, the discharge pipe is aligned with at least one of the discharge holes on said second end of said first means and being inserted into the brush.

11. The cosmetic brush according to the claim 10, wherein the discharge pipe is formed to have a length to reach inside the brush to apply the cosmetic powder uniformly on a skin portion of a user when a user is using the brush, and to move forwardly to an external end of the brush when the brush is out of use and kept in.

12. The cosmetic brush according to the claim 8, wherein a packing is interiorly formed on an inner surface of the connect cap to surround said discharge holes of the first means.

13. The cosmetic brush according to the claim 8, wherein the guide means and the sliding means are rotatably coupled with each other by force fitting.

14. The cosmetic brush according to the claim 8, wherein a fixing stop is formed on both ends of the slide aperture of the sliding means, respectively, and coupled with the guide protrusion of the brush to prevent the further sliding movement of the brush by a longitudinally applied force on the brush or the sliding means.
