TECHNICAL FIELD The present invention relates to a mascara container as a kind of a cosmetic tool, and more particularly, to a mascara container capable of hermetically sealing a mascara solution storage section and conveniently protruding and recessing a brush.

BACKGROUND ART FIG. 1 is an exploded perspective view of a conventional mascara container. As shown in FIG. 1, the conventional mascara container comprises a handle 100, a brush 120, a brush bar 110, and a mascara solution storage section 130. In particular, the handle 100, the brush 120, and the brush bar 110 are constructed as one body. The mascara container is a cosmetic tool for dip the brush 120 in the mascara solution and applying the mascara solution to eyelashes. When a user puts on mascara make-up, the user dips the brush 120 in the mascara solution of mascara solution storage section 130, and then takes out the brush 120 from the mascara solution storage section 130. The conventional mascara container has a problem in that the amount of the mascara solution applied on the brush 120 cannot be adjusted. If a large amount of the mascara solution is applied to the brush 120, the mascara solution may be run down from the brush 120. On the other hand, if a small amount of the mascara solution is applied to the brush 120, the user must inconveniently dip the brush 120 in the mascara solution of mascara solution storage section 130 again. In addition, when the user takes out the brush 120 from the mascara solution storage section 130, the mascara solution storage section 130 is exposed to air. Therefore, the mascara solution may be too dried and hardened to use. In addition, the brush of the mascara container must have a "comb" function of uniformly applying the mascara solution to the eyelashes to prevent the mascara-applied hairs of the eyelashes from sticking to each other. As an approach for achieving the comb function of uniformly applying the mascara solution to the eyelashes, a central portion of the brush is made of stiff hairs, and end portions thereof are made of soft hairs. In addition, as an approach for preventing the mascara solution from being applied to only a portion of the eyelashes, the brush is designed to have a shape of oval or trapezoid. However, these approaches cannot completely overcome the aforementioned problems.

The first sealing member 232 is attached to the distal end of the brush 230. When the brush 230 is inserted into the mascara solution storage section 210, the first sealing member 232 completely seals an injection hole of the mascara solution storage section 210. The brush bar moving screw section 236 is constructed as a main body of the brush bar 234. The one portion of the brush bar moving screw section 236 is located within the handle 240, and the other portion thereof is located within the mascara solution storage section 210. The brush bar moving screw section 236 is designed to move along an inner surface of an inner moving section 226 of the storage section adjusting member 220 described below. By turning the handle 240, the brush bar moving screw section 236 moves up and down along the inner moving section 226 of the storage section adjusting member 220, so that the brush 230 attached to the other end of the brush bar 234 can protrude from or return to the mascara solution storage section 210. The mascara solution storage section 210 of the mascara container stores the mascara solution therein and accommodates the brush 230 of the brush bar 234. In addition, the mascara solution storage section 210 has the injection hole 214 at the end thereof, so that the brush bar 234 protrudes from or returns to the mascara solution storage section 210 through the injection hole 214. A second sealing member 212 is provided to an inner surface of the injection hole 214 in order to increase sealing performance of the mascara container. When the brush 230 protrudes from or returns to the mascara solution storage section 210, the second sealing member 212 enables the brush bar 234 to completely seal the injection hole 214. Preferably, the second sealing member 212 is made of a packing material and has a shape of ring. The handle 240 accommodates the brush bar moving screw section 236 therein. The handle 240 serves as a handle for mascara container. The one end of the handle 240 is attached to a main body 221 of the storage section adjusting member 220. When the user turns the handle 240, the brush bar moving screw section 236 disposed in the handle 240 moves up and down along grooves formed on an inner surface of the inner moving section 226 of the storage section adjusting member 220. As a result, the brush 230 attached to the other end of the brush bar 234 moves up and down. As shown in FIG. 5, by turning the handle 240, the brush 230 attached to the mascara solution storage section 210 protrudes from or returns to the mascara solution storage section 210. In addition, the mascara container according to the preferred embodiment of the present invention further comprises the storage section adjusting member 220 for adjusting an inner space of the mascara solution storage section 210. The storage section adjusting member 220 includes the main body 221, the inner moving section 226, and a press valve 222.

The grooves formed on the main body 221 are engaged with the threads formed on the outer surface of the inner moving section 226. In addition, the inner moving section 226 is designed to surround the outer surface of the brush bar 234 corresponding to the inner surface of the main body 221 of the storage section adjusting member 220. The inner moving section 226 has a shape of cylinder. The threads are formed on the outer surface of the cylinder. The threads are engaged with the grooves formed on the inner surface of the main body 221. In addition, grooves are formed on an inner surface of an end portion of the inner moving section 226 contacting the handle 240 to be engaged with brush bar moving screw section 236. Therefore, the brush bar moving screw section 236 can move up and down along the grooves the inner moving section 226. The press valve 222 is disposed at an end portion of the inner moving section 226 of the storage section adjusting member 220 contacting the mascara solution storage section 210. The press valve 222 has a function of preventing the mascara solution from leaking out from the mascara solution storage section 210. When the inner moving section 226 engaged with the main body 221 of the storage section adjusting member 220 moves up and down by turning the main body 221 of the storage section adjusting member 220, the press valve 222 disposed at the end portion of the inner moving section 226 also moves up and down. Therefore, as shown in FIG. 6, when the user turns the main body 221, the press valve 222 can be moved up and down in the mascara solution storage section 210, so that the inner space of the mascara solution storage section 210 can be widened or shortened. In a case where there is a small amount of the mascara solution in the mascara solution storage section 210, the inner space is shorted by moving the press valve 222, so that it is possible to uniformly apply the mascara solution to the brush 230. In addition, it is possible to prevent the mascara solution from adhering to the inner surface of the mascara solution storage section 210. Now, constructions and operations of a mascara container according to another embodiment of the present invention will be described.
