Abstract

A cosmetic brush for applying make-up which includes a brush member, a main body located at the lower portion of the brush member and a movable bar connected to an intermediate coupler and reciprocally disposed to generate air pressure and to discharge cosmetic powder from the main body to the brush member by pushing up the main body when applying the make-up, wherein the movable bar includes vertical grooves and a press-ring and can move up and down by pushing the main body combined with the intermediate coupler containing the movable bar, so that the cosmetic powder housed in the body is conveyed through a powder transport duct positioned at the top portion of an upper movable body through the vertical grooves in the movable bar formed on top portion of the intermediate coupler and then distributes the cosmetic to the brush member side in a desirable distribution, resulting in improved convenience for the make-up user with an easier and simpler operation.

Claims3

Dependent claims

A cosmetics brush which comprises:

a main body for receiving a cosmetic powder;
an intermediate coupler screw-coupled to the top portion of the main body and formed with an auxiliary brush for distributing the powder to a main brush and a movable bar provided with vertical grooves and containing an opening/closing part with a threshold and a press-ring;
an upper movable body which includes a powder transport duct which is inserted by the movable bar into the intermediate coupler and having a threshold connected to the opening/closing part and is coupled with the intermediate coupler by means of guide grooves at both sides of inner bottom part of the movable body;
and
a repulsive spring disposed between the upper movable body and the intermediate coupler to hold the upper movable part apart from the main body at a desired interval,
whereby when the main body is pushed up, the movable bar is raised which allows the press ring to apply pressure to the power transport duct thereby transporting cosmetic powder to the powder transport duct through the vertical grooves arranged around the movable bar, for discharge to the auxiliary brush which, in turn, distributes the cosmetic powder uniformly to the main brush.
