Abstract: A cosmetic brush which includes a cylindrical cap, a supporting tube mounted inside, of the cap, an upright-standing stem movably received in the tube, and a cosmetic container. A tuft of bristles is fixed on a lower end of the stem. A spring is disposed inside of the cap such that the stem is biased downwardly inside of the tube. The stem has a latching protrusion and the tube has a guide slit to receive the latching protrusion. The downward movement of the stem is stopped by the guide slit when the tuft of bristles is exposed outside of the tube. When the supporting tube is inserted into the container, the latching protrusion is latched and pushed upwards by the top opening of the container, thereby allowing the stem and the tuft of bristles to be raised so as to be received inside of the tube.

Abstract: The present invention relates to a cosmetic brush in which a tuft of bristles automatically gets in and out of the inside of a supporting tube by rotating the cap so as to be screw-engaged or screw-disengaged with/from the container, so that problems such as bending or spreading of the tuft of bristles and the like generated due to its twist can be prevented when rotating the tuft of bristles in a liquid cosmetics having high-viscosity.
