2. Discussion of Related Art

According to a conventional art, a screw rod with which a piston is thread-coupled to ascend and descend and in which a liquid cosmetic guiding passage is formed so that a ball for opening and closing the liquid cosmetic guiding passage is elastically supported by a spring in the liquid cosmetic guiding passage is provided in a container that stores the liquid cosmetic and is coupled with a body.

Therefore, according to the conventional art, a large number of parts are coupled with each other and the structure is complicated so that manufacturing expenses increase. Also, a user must hold the container and rotate the body several times during use, which is inconvenient.

SUMMARY OF THE INVENTION

In order to solve the above-described problems, it is an object of the present invention to provide a cosmetic case in which a supporting cap to which a brush is fixed is fixed to the upper side of a tube-shaped container that stores liquid cosmetic and is coupled with a discharger closed after discharging liquid cosmetic and a cap is thread-coupled with the upper side of the tube-shaped container so that the discharger coupled with the supporting cap ascends and descends by opening and closing the cap. When the cap ascends, a ring-shaped step in the upper end of a liquid supplying container is opened so that a through hole and a liquid guiding passage formed by an inner protrusion wheel step are connected to a discharge hole and that the liquid cosmetic in the tube-shaped container is discharged to the brush. When the cap descends, the ring-shaped step in the upper end of the liquid supplying container is pressed and closed so that the liquid cosmetic stored in the tube-shaped container does not leak and that a user can safely carry the cosmetic case. Since the cap is thread-coupled with the upper side of the tube-shaped container, it is possible to prevent the liquid cosmetic from leaking and from being contaminated.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1 to 4are exploded perspective views of a cosmetic case according to the present invention and sectional views illustrating the coupled state and the operation state of the cosmetic case according to the present invention.

An opening3is formed in the upper side of a male thread2provided on the outer circumference wall of a tube-shaped container1and a step4and a ring-shaped step5and an inner protruded wheel step7are formed on the inner circumference wall of the tube-shaped container1in the lower side of a liquid supplying container6so that an additional discharger10can be inserted to ascend and descend while being provided with a sealing O-ring20.

A liquid guiding passage11is horizontally disposed in the center of the discharger10and is connected to a discharge conduit12which vertically penetrates the center of the discharger10. A pressing plate31ais formed on the circumference of a supporting cap31to which a brush30is fixed and a groove ring33is formed in the lower end and on the outer circumference wall of the discharger10so that the groove ring33is fixed to engage with the protrusion ring13provided on the inner circumference wall and in the upper side of the supporting cap31.

A groove14into which the sealing O-ring20is inserted and a locking step15are formed on the outer circumference wall and in the upper side of the discharger10. A structure containing slanted circumference walls16whose upper side is wide and whose lower side is narrow is formed below the liquid guiding passage11. Stepped jaws17and17aare formed in the lower end of the structure defining the slanted circumference walls16, the upper side of which is wide and the lower side of which is narrow. A column19which supports the jaws17and17ais provided with a divided opening18which supplies liquid cosmetic.

As described above, the supporting cap31to which the brush30is fixed is connected to the protrusion ring13of the discharger10and the discharger10which contains the sealing O-ring20provided in the groove14is inserted into the opening3of the tube-shaped container1such that the sealing O-ring20tightly seals the inner circumference wall of the opening3. The locking step15of the discharger10engages the step formed on the inner circumference wall of the opening3, whereby the slanted circumference wall16of the discharger10presses and closes the ring-shaped step5of the opening3. The column19with the divided opening18extends through hole7aformed by the inner protrusion wheel7disposed in the inner circumference wall and in the lower side of the tube-shaped container1to connect the liquid supplying container6to the inside of the tube-shaped container1through the divided opening18.

As described above, a cap40is thread-coupled with the upper side of the tub-shaped container1. A female thread41corresponding to the male thread2formed in the upper side and on the outer circumference wall of the tube-shaped container1is formed on the inner circumference wall and in the lower side of the cap40, respectively, and a pressing step42and an inner locking wheel43are respectively formed on the inner circumference wall and in the center of the cap40so that the cap40is thread-coupled to the upper side of the tube-shaped container1. Therefore, the pressing step42formed on the inner circumference wall of the cap40is fixed to the upper side of the discharger10to press against the pressing plate31alocking flanges formed in the upper side of the supporting cap31to which the brush30is fixed and to have the discharger10descend. Therefore, the slanted circumference wall16whose upper side is wide and whose lower side is narrow formed at the outer circumference wall of the discharger10, presses and closes the ring-shaped step5formed on the inner circumference wall and in the upper side of the tube-shaped container1to intercept the liquid supplying container6connected to the divided opening18and the liquid guiding passage11connected to a discharge hole12.

In the above-described state, the pressing plate31ais pressed by the pressing step formed on the inner circumference wall in the center of the cap40and locked by the inner locking wheel (locking slots)43. When the cap40is rotated to be opened, the pressing plate31alocked by the inner locking wheel43formed on the inner circumference wall and in the center of the cap40ascends to a predetermined height together with the cap40that ascends as it is rotated.

At this time, the discharger10coupled with the supporting cap31including the pressing plate31alocking flanges ascends so that the slanted circumference wall16of the discharger10separates from the ring-shaped step5of the opening3to open the upper side of the liquid supplying container6. Therefore, the through hole7aformed by the inner protruded wheel step7formed on the inner circumference wall and in the lower end of the tube-shaped container1is connected to the liquid guiding passage11and the discharge hole12so that the liquid cosmetic in the tube-shaped container1can be discharged to the brush30. Simply stated, as the cap is unscrewed, the stopped jaws will engage inner protrusion wheel7and the pressing plate31awill snap out of a groove on the cap to enable the cap to be removed.

FIGS. 5 and 6are sectional views illustrating a cosmetic case according to a first embodiment of the present invention. As described in the structure of the discharger10ofFIGS. 1 to 4, the liquid guiding passage11connected to the discharge hole12is extended downward by the use of a supporting plate50having a bottom planar surface51.

The supporting plate50is positioned to ascend and descend in the liquid supplying container6. An opening and closing ball52is provided under the supporting plate50to open and close the through hole7aformed by the inner protruded wheel step7of the liquid supplying container6. An outer locking protrusion wheel53is provided on the outer circumference wall and in the lower end of the discharger10to which the brush30is fixed. An inner locking protrusion wheel54is provided on the inner circumference wall and in the upper end of the tube-shaped container1into which the discharger10is inserted to ascend and descend. The outer locking protrusion wheel53and the inner locking protrusion wheel54are coupled with each other so that the discharger10does not deviate when the tube-shaped container1is pressed.

FIGS. 7 and 8are sectional views illustrating a cosmetic case according to a second embodiment of the present invention. As described with reference to the structure of the discharger10ofFIGS. 1 to 6, the column19formed below the slanted circumference wall16defines the liquid guiding passage11connected to the discharge hole12said passage11being further defined by the supporting plate50formed by extending the liquid guiding passage11in the downward direction. Therefore, the through hole7aformed by the inner protruding wheel step7that forms the liquid supplying chamber6is directly opened and closed.

In the state where the cap40is thread-coupled with the tube-shaped container1, as illustrated inFIG. 3, the pressing plate31aof the supporting cap31to which the brush30is attached engaged with the upper side of the discharger10by the pressing step42formed at the inner circumference wall in the upper side of the cap40so that as the discharger10descends, the slanted circumference wall16presses and seals up the ring-shaped step5of the tube-shaped container1. Therefore, it is possible to safely carry the cosmetic case without the danger of the liquid cosmetic stored in the tube-shaped container1leaking to the outside.

FIGS. 9 and 10are sectional views illustrating a cosmetic case according to a third embodiment of the present invention. By the male threads2of the upper outer circumferential wall of the tube-shaped container1ofFIGS. 1 to 8, and by the outer protruding ring2aof the tube-shaped container1, and an inner protruding ring41aof the cap40, the cap40on the top of the tub-shaped container1can be forcibly opened without female treads41formed in the lower inner circumferential wall of the cap40. Moreover, without the liquid guiding passage11formed in the center of the discharge hole12, a vertical body60which is a vertical extension of the discharge hole12, is formed. Corresponding to the structure of an upper step61formed in the upper side of the vertical body60, a groove ring62is formed in the lower side of the outer circumferential wall of the vertical body60and several erected pieces70are formed in the upper inner circumferential wall of the tube-shaped container1to open the circumference of the liquid supplying container6such that a liquid supplying chamber71is formed. A through-hole7aformed in the lower end is closed such that an opening and closing cap72, in which the inner protruding ring72ais formed in correspondence to the groove ring62of the vertical body60, is formed in the upper side of the inner circumferential wall to open and close the discharge hole12formed in the vertical body60. An elastic spring80is disposed between the upper step61of the vertical body60and the opening and closing cap72such that the opening and closing cap72is safely operated by the erected pieces70for defining the liquid supplying chamber71. An inner locking protruding wheel73is formed in the inner lower circumferential wall of the supporting cap31and is engaged with the upper side of the discharger10to cover the supporting cap31. An outer locking protruding wheel74is formed in the upper side of the outer circumferential wall of the tube-shaped container1and is engaged with the inner locking protruding wheel73such that the discharger10is not separated when pressing the tube-shaped container1.

In the liquid cosmetic case according to the preferred embodiment of the present invention as described above, the state of the cap40being thread-coupled with the tube-shaped container1, as shown inFIG. 1, is the state in which the pressing plate31aof the supporting cap31is pressed by the pressing step42formed in the upper side of the inner circumferential wall of the cap40such that the slanted circumference wall16presses and closes the ring-shaped step5of the tube-shaped container1. Thus, the liquid cosmetic stored in the tube-shaped container1does not leak and is safely stored.

When using the liquid cosmetic case according to the preferred embodiment of the present invention, as shown inFIG. 4, the cap40thread-coupled with the upper side of the tube-shaped container1is turned to open the tube-shaped container1. At that time, as the pressing plate31a, locked to the inner locking wheel43formed in the center of the inner circumferential wall of the cap40, is rotated to ascend to a predetermined height together with the ascending cap40, the discharger10coupled with the supporting cap31in which the pressing plate31ais formed also ascends together them so that the slanted circumference wall16of the discharger10is separated from the ring-shaped step5of the opening3and the upper side of the liquid supplying container6is opened. The divided opening18of the discharger10, the liquid supplying container6, the liquid guiding passage11, and the discharge hole12all communicate with each other such that when the tube-shaped container1is held by hand and pressed, the liquid cosmetic stored in the tube-shaped container1is discharged and impregnated into the brush30.

When the discharger10ascends due to the pressing of the tube-shaped container1, the stepped jaws17and17aformed in the lower sides of the divided opening18are obstructed by the inner protruding wheel step7forming the through hole7aso that the discharger10does not excessively ascend.

Moreover, as shown inFIGS. 5 and 6illustrating the first preferred embodiment of the present invention, in the state of opening the through-hole7adue to the pressure generated by opening the cap40thread-coupled with the tube-shaped container1and pressing the tube-shaped container1, the opening and closing ball52ascends and the tube-shaped container1communicates with the liquid supplying container6, the liquid guiding passage11, and the discharge hole12through the through-hole7asuch that the liquid cosmetic stored in the tube-shaped container1is discharged through the discharge hole12and is impregnated into the brush30.

By repeating the above actions, the liquid cosmetic stored in the tube-shaped container1. At that time, the outer locking protrusion wheel53of the supporting cap31fixed to the upper side of the discharge10is locked to the inner locking protrusion wheel54formed in the upper side of the inner circumference wall of the opening3so that ring the discharger10is not separated and is safely used.

As shown inFIGS. 7 and 8illustrating the second preferred embodiment of the present invention, the discharger10ascends, as shown inFIG. 7, due to the pressure generated in the tube-shaped container1by opening the cap40thread-coupled with the tube-shaped container1and pressing the tube-shaped container1, and the slanted circumference wall16for closing the through-hole7aformed by the inner protruded wheel step7ascends such that the through-hole7a, the liquid guiding passage11, and the discharge hole12communicate with each other so that the liquid cosmetic stored in the tube-shaped container1is discharged through the discharge hole12and is impregnated into the brush30.

After use, the cap40is thread-coupled with the upper side of the tube-shaped container1such that the slanted circumference wall16securely closes the through-hole7aso that the liquid cosmetic stored in the tube-shaped container1is prevented from leaking.

As shown inFIGS. 9 and 10illustrating the third preferred embodiment of the present invention, when opening the cap40thread-coupled with the tube-shaped container1, the pressing step42formed in the central portion of the inner circumference wall of the cap40releases the pressing plate31aengaged with the upper side of the discharger10and is elastically supported by the upper step61of the vertical body60of the discharger10and the upper side of the opening and closing cap72such that the discharger10ascends due to the elastic force of the elastic spring60installed between the circumference of the vertical body60and the erected pieces70. At this time, the lower side of the discharge hole12pressing and closing the lower side of the vertical body60is opened such that the tube-shaped container1communicates with the discharge hole12by the communication of the several erected pieces70with the discharge hole12.

Thus, due to the pressure generated by pressing the tube-shaped container1, the liquid cosmetic stored in the tube-shaped container1is discharged and impregnated into the brush30.

As such, after using the brush30into which the liquid cosmetic is impregnated, the cap40is again thread-coupled with the upper side of the tube-shaped container1such that the pressing step42of the cap40presses the pressing plate31aof the supporting cap31engaged with the upper side of the discharger10and the lower side of the vertical body60contacts the inner bottom of the opening and closing cap72so that the inner protruding ring72ain the inner circumference wall of the opening and closing cap72is engaged with the groove ring62formed in the outer circumference wall of the vertical body60. Thus, the tube-shaped container1and the discharge hole12are securely pressed and closed.

At this time, since the elastic spring80is elastically pressed between the upper step61of the vertical body60and the upper circumference of the opening and closing cap72, the liquid cosmetic stored in the tube-shaped container1does not leak and is safely stored.

Therefore, the liquid cosmetic case according to the preferred embodiments of the present invention is structured such that the discharger10coupled with the supporting cap31automatically ascends and descends due to the opening and closing of the cap40. When the cap40ascends, the ring-shaped step5as the upper side of the liquid supplying container6is opened such that the through-hole7adefined by the inner protruding wheel step7, the liquid guiding passage11, and the discharge hole12, communicate with each other so that the liquid cosmetic in the tube-shaped container1is discharged to the brush30. When the cap40descends, since the ring-shaped step5as the upper side of the liquid supplying container6is pressed and closed, the liquid cosmetic stored in the tube-shaped container1does not leak and is safely stored.

As described above, the supporting cap, in which the brush is attached, is fixed to the upper side of the tube-shaped container for storing the liquid cosmetic and the discharger for discharging the liquid cosmetic is coupled with the upper side of the tube-shaped container such that the cap is thread-coupled with the tube-shaped container so that the discharger coupled with the supporting cap automatically ascends and descends due to the opening and closing of the cap. Thus, when the cap ascends, the ring-shaped step as the upper side of the liquid supplying container is opened such that the through-hole formed by the inner protruding wheel step, the liquid guiding passage, and the discharge hole communicate with each other so that the liquid cosmetic in the tube-shaped container is discharged to the brush. When the cap descends, and the ring-shaped step as the upper side of the liquid supplying container is pressed and closed, the liquid cosmetic stored in the tube-shaped container does not leak and is safely stored. When using the liquid cosmetic case, since a desired amount of the liquid cosmetic is easily discharged by repeatedly pressing the tube-shaped container by the user, loss of the liquid cosmetic can be prevented.
