Patent ID: 7448393

Claim:
A cosmetic brush comprises; a cylindrical cap; a supporting tube vertically extended, one end of which is mounted inside of the cylindrical cap; an upright-standing stem movably received in the supporting tube, the upright-standing stem having a tuft of bristles fixed on a lower end thereof; a spring disposed inside of the cylindrical cap such that the stem is elastically downwardly biased inside of the supporting tube; and a cosmetic container including a screw thread portion formed on an upper portion thereof, an inner cap mounted at an inner circumference of the screw thread portion and a cylindrical body formed at a lower portion thereof to have a width larger than that of the inner cap, the inner cap having an inlet/outlet hole with a narrow width formed on a top end thereof, wherein the stem comprises a latching protrusion outwardly protrusively formed on an outer peripheral surface of an upper portion thereof, and the supporting tube comprises a guide slit formed longitudinally on an upper portion of the supporting tube to receive the latching protrusion, the elastically downward movement of the stem being stopped by the guide slit when the tuft of bristles is exposed outside of a lower end of the supporting tube, and wherein when the supporting tube is inserted into the container through the inlet/outlet hole by means of the screw-engagement between the cap and the inner cap with each other, the latching protrusion is latched and pushed upwards by the inner cap, to thereby allow the stem and the tuft of bristles to be raised so as to be received inside of the supporting tube.
