## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
Korean patent application KR 10-2011-0119029, filed Nov. 15, 2011, is incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to a cosmetic case for powder, and more particularly, to a cosmetic powder case which securely stores a makeup brush that is taken out and conveniently used for a makeup.
DESCRIPTION OF THE RELATED ART
Recently, the demand of functional cosmetics increases over the world, and new materials and formulations are successively developed.
Accordingly, cosmetic cases for maximally protecting the functions of effective components and providing use convenience are actively developed.
Cosmetics may be classified into solid type cosmetics and solid/liquid type cosmetics. There are a number of cosmetics having various functions and forms, such as makeup bases, eye shadows, two way cakes, powder pacts, and skin covers, according to users' tastes and skin conditions.
A makeup cosmetic may be formed by injecting an oily powder source into a case, and then pressing the source with a press. Such makeup cosmetics may be typically compressed to a solid state. Particularly, powder sources may be formed by mixing a coloring matter, a binder, and a base material such as talc, titanium dioxide, mica, silica, nylon powder, poly methyl methacrylate, sericite, kaolin, or bismuth oxychloride. In this case, the binder may be selected from the group consisting of silicone-based oil, hydrocarbon-based oil, advanced fatty acid-based oil, high alcoholic oil, ester-based oil, glyceride-based oil, lanoline-based oil, animal oil, and vegetable oil.
Cosmetics compressed in a solid state may be applied to a user's face by using a cosmetic puff. In this case, the amount of a cosmetic attached to the puff may be varied. In addition, an amount of the cosmetic applied initially to the face may be greater than that of the cosmetic applied later to the face. As a result, the cosmetic is unevenly applied to the face.
To address this limitation, a cosmetic case may be filled with cosmetic powder, and an opening of the case may be closed with a puff, so that the powder can be uniformly discharged through the puff.
A cosmetic case disclosed in Korean Utility Model Registration No. 20-0431987 includes: a lower body including a storing space therein; an upper body coupled to the top of the lower body; a storing case coupled to an inner portion of the upper body; and an opening/closing cover coupled to the upper body. A support plate is coupled to the inner portion of the cover, and includes a leaf spring on the rear surface thereof to apply elastic force to the outside. A packing member formed of at least one of rubber, silicone, and soft synthetic resin to provide a sealing function is coupled to the front edge of the support plate, and protrude forward.
However, typical cosmetic powder cases do not have a brush storage. Even when a cosmetic powder case has a brush storage, the brush may be accidentally removed and lost from the cosmetic power case.
A compact cosmetic case assembly disclosed in Korean Examined Utility Model Publication No. 1996-0008289 includes: a hollow case including a screw thread 11 on the outer surface thereof; a partition plate removably coupled to the case, and having a surface with holes; a puff placed on the partition plate; an inner cover including a screw thread engaging with the screw thread of the case; an upper cover coupled to the inner cover, and integrally including a storage having a certain shape that is formed by cutting a certain portion of a plane and a circumferential surface; and a cosmetic brush assembly removably inserted in the storage and having a shape corresponding to the storage.
In addition, a cosmetic case assembly disclosed in Korean Utility Model Laid-open Publication No. 1997-048837 includes: a cosmetic brush; a slider fixing an end of the cosmetic brush; and a case in which the slider can moves, and the cosmetic brush is pushed in and pulled out according to moving positions of the slider.
In addition, a cosmetic case disclosed in Korean Utility Model Registration No. 20-0209938 includes: a body including a hollow part at the upper portion thereof to receive a certain amount of contents, and including a brush storage at the lower inner portion thereof to store a brush; an opening/closing cover hinged to the upper side of the body, and including a seeing through window in the center thereof to perceive the contents with a naked eye, and including a fit recess at an upper side opposed to a hinge portion thereof, wherein a folded portion of a brush is fitted in the fit recess to close the hollow part; and the brush including a protective cap covering bristles and a grip to protect the bristles, and stored in the brush storage of the body. The folded portion is fitted in the cover, to thereby couple the body to the cover.
However, such cosmetic cases have a complicated brush storage, and thus, mold costs thereof are high, and the brush may be accidentally removed and lost.

Openings 133a and 133b are formed by cutting left and right portions of the rotation guide 133. The guide recess 134 is provided in plurality at the front and rear sides of the openings 133a and 133b (along a Y axis), and are formed in the inner surface of the rotation guide 133. An insertion recess 135 is formed above the guide recess 134.
The brush holder 140 is rotatably coupled to the inner portion of the rotation guide 133.
A flange 142d contacting the upper end of the rotation guide 133 is disposed at an upper edge of the brush holder 140. A knurling portion 142e is formed on an outer surface of the flange 142d. The knurling portion 142e makes it possible for a user to rotate the brush holder 140 without a slip.
The guide protrusion 141 is formed on the outer circumferential surface of the brush holder 140 to correspond to the guide recess 134.
The insertion recess 135 facilitates inserting of the guide protrusion 141 into the guide recess 134 when the brush holder 140 is coupled to the inner portion of the rotation guide 133.
The brush insertion part 142 is formed in the upper portion of the brush holder 140.
A brush inlet 142a and a brush outlet 142b are formed at the left and right sides of the brush insertion part 142 (along an X axis) to correspond to the openings 133a and 133b. 
An exposure hole 142c is formed in the upper portion of the brush insertion part 142 to expose the handle 151 of the brush 150 out of the brush holder 140, so that the brush 150 can be easily taken out.
The handle 151 exposed through the exposure hole 142c is pressed and pushed with a user's hand to slide the brush 150, whereby the brush 150 can be easily taken out from the brush holder 140.
When the openings 133a and 133b, the brush inlet 142a, and the brush outlet 142b are aligned in the left and right direction (along the X axis) (in an open state), the brush 150 can be slid, and taken out from the brush holder 140.
When the openings 133a and 133b, the brush inlet 142a, and the brush outlet 142b are not aligned in the left and right direction, and the openings 133a and 133b are aligned along the Y axis (in a closed state), the brush 150 is prevented from being accidentally removed from the brush insertion part 142.
The brush 150 including the handle 151 and the hairs 157 fixed to the handle 151 is inserted and stored in the brush insertion part 142, and is selectively pulled out and used.
A tension piece 142g for fixing the brush 150 is formed on a bottom surface 142f of the brush insertion part 142. Fixing recesses 151a are formed in top and bottom surfaces of the handle 151 to correspond to the tension piece 142g. 
An aligning recess 151b for guiding sliding of the brush 150 is formed on a center line L of the handle 151.
A fixing protrusion 134a for fixing the guide protrusion 141 is formed on a bottom of the guide recess 134.
Hereinafter, an operation of the cosmetic powder case 100 configured as described above will now be described.
A certain amount of powder is stored in the space 111 of the case main body 110, and a portion of the powder is supplied through the powder discharge holes H of the sifter 120. Then, a user uses the puff P or the brush 150 to apply the powder to her face.
To store the brush 150 in the brush insertion part 142, the user holds and rotates the brush holder 140.
Since the guide protrusion 141 is inserted in the guide recess 134, the brush holder 140 smoothly rotates. At this point, the openings 133a and 133b, the brush inlet 142a, and the brush outlet 142b are aligned with one another.
Then, the handle 151 of the brush 150 is inserted through the brush inlet 142a. When the brush 150 is further inserted, the tension piece 142g is elastically inserted in the fixing recess 151a of the handle 151 so as to prevent an accidental movement of the brush 150.
The brush holder 140 is held and rotated reversely. The guide protrusion 141 is fixed to the fixing protrusion 134a to prevent an accidental rotation of the brush holder 140. At this point, the openings 133a and 133b are not misaligned with the brush inlet 142a and the brush outlet 142b. 
Accordingly, the rotation guide 133 closes the brush inlet 142a and the brush outlet 142b so as to prevent an accidental removal of the brush 150 from the brush insertion part 142, and thus, the brush 150 is securely stored in the brush insertion part 142, and is prevented from being lost.
When the brush 150 is taken out for a makeup, the brush holder 140 is held and rotated. At this point, the openings 133a and 133b, the brush inlet 142a, and the brush outlet 142b are aligned with one another. The handle 151 is pressed through the exposure hole 142c, and is slid to take out the brush 150 through the brush outlet 142b. 
As described above, according to the embodiments of the present invention, a brush holder is rotatably installed on a cap, and a brush is inserted and stored in the brush holder, thereby effectively preventing the brush from being lost. In addition, a structure for storing the brush is simplified, to thereby significantly decrease mold costs.
In addition, the brush can be conveniently taken out for a makeup, and be inserted and be stored in a brush insertion part of the brush holder. Since a handle of the brush is exposed out of the brush holder, the handle can be pressed and be easily taken out with a user's hand.
In addition, a tension piece makes it possible to securely store the brush in the brush insertion part without a movement.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
