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.

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&#39;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 
     Accordingly, the present invention is directed to a powder cosmetic brush that substantially obviates one or more problems due to limitations and disadvantages of the related art. 
     Accordingly, the present invention is directed to a powder cosmetic brush having a structure in which a sleeve gathers hairs when a cap is closed, a hair holder is rotated together by rotating the sleeve, and a powder discharge hold and a communication hole are maintained in an open state to discharge powder within a bottle or the powder discharge hole and the communication hole are maintained in a close state to prevent the powder within the bottle from being discharged, wherein the powder is discharged or not discharged by using the sleeve to simplify the close/open structure, thereby significantly reduce mold manufacturing costs. 
     According to an aspect of the present invention, there is provided a cosmetic brush including: a cylindrical bottle on which a male screw is disposed along an upper outer surface, the cylindrical bottle containing powder therein; a body in which a female screw is disposed on an inner bottom surface to be coupled to an upper portion of the cylindrical bottle, a through hole is defined in a center of a lower bottom surface thereof, a plurality of powder discharge holes are defined along an edge of the lower bottom surface, and a hook and a locking projection are disposed along an upper outer surface thereof; a hair holder inserted into the body and in which hairs are fixed to an upper portion thereof, a plurality of communication holes respectively communicating with the power discharge holes are defined in a lower portion thereof, and a wedge projection inserted into the through hole is disposed on a central bottom surface thereof; a filter inserted into the wedge projection to filter the powder passing through the powder discharge holes; a sleeve disposed to be vertically slidable along an outer surface of the hair holder, the sleeve being coupled to the hair holder so that the communication holes respectively match the powder discharge holes to open the communication hole; and a cap supported by the hook, the cap being detachably coupled to an upper portion of the body, wherein the sleeve gathers the hairs when the cap is closed and the hair holder is rotated together with the sleeve to match the power discharge holes with the communication holes, thereby maintaining an open state and discharging the powder within the bottle or mismatch the power discharge holes with the communication holes, thereby maintaining an close state and preventing the powder within the bottle from being discharged. 
     A hook groove may be horizontally defined in an upper outer surface of the hair holder, a dropping down prevention hook may be disposed on a lower outer surface of the hair holder, a fixing groove may be vertically disposed on an outer surface of the hair holder, a hook projection may be disposed on a lower portion of the sleeve to correspond (coupled) to the hook groove and the dropping down prevention hook, and a fixing projection may be disposed on the lower portion of the sleeve to correspond to the fixing groove. 
     A locking hook locked with a bottom surface of the body may be disposed on a lower portion of the hair holder, and an O-ring may be disposed on a bottom surface of the hair holder. 
     A stopper may be disposed on a bottom surface of the body, and a key rod may be disposed on a lower portion of the hair holder so that the key rod is selectively hooked on the stopper.

     Hereinafter, the powder cosmetic brush according to the embodiment of the present invention will be described in more detail. 
     The bottle  110  has a cylindrical shape with a lower side closed and an upper side opened. A space for receiving the powder is defined in the bottle  110 . The male screw  112  (see  FIGS. 3 to 5 ) is disposed along the upper outer surface of the bottle  110 . 
     Also, the female screw  121  (see  FIGS. 3 to 5 ) is disposed on the inner bottom surface of the body  120  so that the body  120  is coupled to the upper portion of the bottle  110 . 
     The through hole  121  is defined in the center of the lower bottom surface of the body. Also, the plurality of powder discharge holes  123  are defined along an edge of the lower bottom surface of the body  120 . The hook  124  and the locking projection  125  are disposed on an upper outer surface of the body  120  (see  FIG. 13 ). 
     A stopper  128  protrudes from a bottom surface of the body  120 . A key rod  138  (see  FIG. 16 ) is disposed on the hair holder  130  so that the key rod  138  is selectively hooked on the stopper  128  (see  FIG. 13 ). 
     The hair holder  130  is inserted into the body  120 , and the hairs H is fixed to an upper portion of the hair holder  130 . Also, a plurality of communication holes  131  respectively communicating with the powder discharge holes  123  are defined in the lower portion of the hair holders  130  (see  FIGS. 3 to 15 ). 
     The wedge projection  132  inserted into the through hole  122  is disposed on a central bottom surface of the hair holder  130  (see  FIGS. 14 to 16 ). 
     A dropping down prevention groove  133   a  and a guide groove  133   b  are defined in an upper outer surface of the hair holder  130 . Also, a dropping down prevention hook  134  is disposed on a lower outer surface of the hair holder  130  (see  FIGS. 14 and 18 ). 
     A dropping down prevention projection  151  is disposed on a lower inner surface of the sleeve  150  to correspond to the dropping down prevention groove  133   a , the guide groove  133   b , and the dropping down prevention hook  134  (see  FIGS. 10 and 21 ). 
     A locking hook  135  locked with a bottom surface of the body  120  is disposed on a lower portion of the hair holder  130 , and an O-ring  170  is disposed between the hair holder  130  and the body  120  (see  FIGS. 18 and 19 ). A hole  171  of the O-ring  170  is defined to constantly communicate with the discharge holes  123  of the body  120  (see  FIGS. 3 ,  19 , and  24 ). 
     The filter  140  filters the powder so that the powder is supplied at a predetermined amount through the powder discharge holes  123 . Also, the filter  140  is inserted into the wedge projection  132  (see  FIGS. 3 to 5 ). 
     The sleeve  150  is disposed to be vertically slidable along the outer surface of the hair holder  130 . When the sleeve  150  is forwardly or reversely rotated, the hair holder  130  linked with the sleeve  150  is forwardly or reversely rotated also. Thus, the powder discharge holes  123  and the communication holes  131  may be closed (see  FIG. 8 ) or opened (see  FIG. 9 ) together with each other. Here, the forward direction represents a direction (clockwise direction) in which the powder discharge holes  123  are closed, and the reverse direction represents a direction (counterclockwise direction) in which the power discharge holes  123  are opened (see  FIGS. 8 and 9 ). 
     The cap  160  is supported by the hook  124  and detachably coupled to the upper portion of the hair holder  130 . A hook projection  160  (see  FIG. 10 ) corresponding to the locking projection  125  is disposed on an inner surface of the cap  160 . 
     Hereinafter, an operation of the powder cosmetic brush  100  according to the embodiment of the present invention will be described in more detail. 
       FIGS. 2 and 4  illustrate a state in which the powder cosmetic brush  100  is closed. Here, the sleeve  150  ascends to close the cap  160  gathering the hairs H. 
     Here, the dropping down prevention projection  151  disposed on the lower inner surface of the sleeve  150  is inserted into the dropping down prevention groove  133   a  defined in the upper outer surface of the hair holder  130  to fix the sleeve  150  in position. 
     Also, when the sleeve  150  is rotated at an angle of about 45° in the forward direction, the hair holder  130  linked with the sleeve  150  is rotated also at an angle of about 45° in the forward direction. 
     The key rod  137  is intercepted by the stopper  128  of the body  120 . Here, the rotation of the hair holder  130  is completed. Here, the powder discharge holes  123  and the communication holes  131  are closed to prevent the powder within the bottle  110  from being supplied toward the hairs H (see  FIG. 7 ). 
       FIG. 6  illustrates a state in which the powder cosmetic brush  100  is opened. Here, the cap  160  is opened to allow the sleeve  150  to descend. Here, the dropping down prevention projection  151  is moved downward along the guide groove  133   b . The sleeve  150  is rotated in the reverse direction. 
     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.
