The housing 230 may be coupled to the upper end of the container body 110 to form the outer shape of the cosmetic container 100 together with the container body. For example, the housing 230 may be formed to have the same outer diameter as the container body 110 .

The housing 230 may be detachably coupled to the upper end of the container body 110 . For example, the upper end of the container body 110 and the lower end of the housing 230 are formed with male and female screws, respectively, and may be screw-coupled to each other. The brush unit 200 may be coupled to each other in various ways other than the screw coupling structure with respect to the container body 110 and is not particularly limited. The lid 111 may be detachably coupled to the upper end of the housing 230 .

A discharge hole 232 is formed in the lower bottom surface of the housing 230 to communicate with the container body 110 so that the powder can be discharged. A plurality of discharge holes 232 may be arranged at intervals along the circumferential direction with respect to the center of the housing 230 as an axis. In the present embodiment, four discharge holes 232 may be arranged at intervals of 90 degrees. The number or size of the discharge holes 232 may be variously modified. A straight vertical groove (refer to 234 in FIG. 4 ) is formed on the inner circumferential surface of the housing 230 in the axial direction. The vertical groove 234 is a portion coupled to the sleeve 260, and this will be described later.

The rotating body 240 is a cylindrical structure with an open top, and is inserted and installed inside the housing 230 . A transfer hole 242 through which the powder is distributed is formed in communication with the discharge hole 232 formed in the housing 230 on the bottom surface of the lower end of the rotating body 240 . The transfer hole 242 is arranged to correspond to the discharge hole 232 and communicates with the discharge hole 232 .

The rotating body 240 may be axially coupled to the bottom surface of the housing 230 to be rotatably installed with respect to the housing 230 . Accordingly, the discharge hole 232 may be opened and closed while the rotating body 240 is rotated with respect to the housing 230 . When the rotating body 240 is rotated, the conveying hole 242 of the rotating body 240 moves with respect to the fixed discharge hole 232, so that the conveying hole 242 communicates with the discharge hole 232 or communicates with the discharge hole ( 232), and it does not work. Accordingly, the discharge hole 232 may be blocked by opening the discharge hole 232 by matching the transfer hole 242 and the discharge hole 232 or displacing the discharge hole 232 .

A transfer pipe 244 having a passage 246 connected to the transfer hole 242 may be formed to extend upwardly in the rotating body 240 . The powder discharged from the discharge hole 232 may be discharged to the upper portion of the conveying pipe 244 through the passage 246 of the conveying pipe 244 connected to the conveying hole 242 .

A powder brush 210 may be installed on the rotating body 240 . The powder brush 210 may be inserted and installed in a space between the transfer pipe 244 and the inner circumferential surface of the rotating body 240 . Accordingly, the powder may be discharged through the discharge hole 232 and the conveying hole 242 and supplied to the powder brush 210 along the conveying pipe 244 .

A cam groove 250 inclined with respect to the axial direction is formed on the outer peripheral surface of the rotating body 240 . The cam groove 250 is a portion coupled to the sleeve 260, and this will be described later.

For shaft coupling between the rotating body 240 and the housing 230 , a rotating shaft 247 is formed to protrude from the lower end of the rotating body 240 along the central axis. In addition, an insertion hole 236 into which the rotation shaft 247 is inserted is formed in the center of the bottom surface of the housing 230 . The rotating shaft 247 of the rotating body 240 is inserted and installed in the insertion hole 236 of the housing 230 , and the rotating body 240 is rotatably installed with respect to the housing 230 .

In the present embodiment, the rotation shaft 247 has a protrusion 248 protruding outward along the outer circumferential surface, and the insertion hole 236 may have a groove portion 237 in which the protrusion 248 is caught along the inner circumferential surface. . Accordingly, when the rotation shaft 247 is inserted into the insertion hole 236 and coupled, the protrusion 248 is engaged with the groove portion 237 so that the housing 230 and the rotation body 240 may be more closely coupled. Accordingly, it is possible to prevent a gap from being generated between the discharge hole 232 formed in the housing 230 and the transfer hole 242 formed in the rotating body 240, and prevent the powder from leaking to the outside through the two members. there will be

As shown in FIG. 3 , this embodiment may further include an airtight part that is installed closely between the rotating body 240 and the housing 230 to prevent a gap between the discharge hole 232 and the transfer hole 242 . .

The airtight part is inserted into the rotating shaft 247 and coupled to the rotating body 240 , and a polygonal sealing pad 280 in which a hole 282 is formed at a position corresponding to the conveying hole 242 , and the rotating body 240 protrudes at the lower end. It may include a guide bar 284 formed to regulate the rotation of the sealing pad 280 .

While the protrusion 248 of the rotation shaft 247 is engaged with the groove portion 237 of the housing 230 , the sealing pad 280 is elastically pressed and pressed between the rotation body 240 and the housing 230 . Accordingly, the sealing pad 280 is more closely adhered to the rotating body 240 and the housing 230 to prevent a gap.

The sealing pad 280 may be formed of a material different from that of the rotating body 240 or the housing 230 . In this embodiment, the sealing pad 280 may be formed of a material having excellent elasticity and adhesion. For example, the sealing pad 280 may be formed of rubber, urethane, or silicone material.

The sealing pad 280 is a plate structure, and a hole 283 into which the rotating shaft 247 of the rotating body 240 is inserted is formed in the center. And the holes 282 are arranged in the circumferential direction with the hole 283 as the center.

The sealing pad 280 may be fitted to the rotating shaft 247 of the rotating body 240 and coupled to the lower end of the rotating body 240 . The sealing pad 280 is not freely rotated with respect to the rotating body 240 but is formed in a polygonal shape such as a rectangular shape so that it can move with the rotating body 240 , and may be fixed by the guide bar 284 .

The guide bar 284 is formed to protrude at the lower end of the rotating body 240 according to the size of the sealing pad 280 to support the side end of the sealing pad 280 . The sealing pad 280 is supported by the guide bar 284 in a state in which the hole 282 formed on the surface coincides with the transfer hole 242 of the rotating body 240 .

In this embodiment, the sealing pad 280 may be more closely attached to the surface of the rotating body 240 and the housing 230 by forming a rib 286 with increased thickness along the periphery or around the hole 283 and the hole 282. there is. Accordingly, the outer periphery of the hole 283 , the hole 282 , or the sealing pad 280 in which a gap may be generated is further pressed into close contact with the flesh portion 286 of the sealing pad 280 to increase airtightness.

A filter 270 for filtering the powder discharged through the discharge hole 232 may be further installed outside the bottom surface of the housing 230 .

The filter 270 may be a porous foam structure having a predetermined thickness in which an open cell is formed. The filter 270 may be formed to have a size that approximately covers the entire discharge hole 232 . Accordingly, the powder may be supplied to the brush unit through the discharge hole in the form of powder of a predetermined size without being agglomerated through the filter 270 .

In the present embodiment, the filter 270 may be replaced with various types according to the viscosity of the powder accommodated in the cosmetic container. For example, when the viscosity of the powder is low, a filter having a small porous open cell size may be installed and used.

The filter 270 may be positioned under the housing 230 by being inserted into the fitting bar 272 extending from the lower end of the rotating body. That is, a fitting bar 272 for fixing the filter 270 by passing through the insertion hole 236 of the housing 230 may be formed at the front end of the rotating shaft 247 of the rotating body 240 to extend into the housing. The fitting bar 272 may be integrally formed with a wedge-shaped conical protrusion 274 fixed to the front end through a hole formed at the center of the filter 270 . In addition, a stopper 276 in the form of a disk for preventing the filter 270 from being separated from the fitting bar 272 may be fitted and coupled to the conical protrusion 274 .

The stopper 276 may be coupled with the conical protrusion 274 of the fitting bar 272 being press-fitted into the hole formed in the center. The stopper 276 is caught on the conical projection 274 and fixed to the fitting bar 272 . The stopper 276 is a member having a relatively larger diameter than the hole formed in the center of the filter 270 , and the filter is caught by the stopper and does not fall off the fitting bar.

If necessary, the filter can be easily replaced and used by separating the stopper and the filter from the fit bar, mounting a new filter on the fitting bar, and fixing the stopper.

In this way, by easily replacing and installing the filter when necessary, it is possible to adjust the powder discharge amount to an optimal state.

As another embodiment, although not shown, the filter may be a single-layer sheet structure in which grid-like eyes are formed. In the case of this structure, the powder does not remain in the filter in the process of filtering the powder, so it is possible to minimize the agglomeration or sticking of the remaining powder to the filter.

A sleeve 260 is installed between the rotating body 240 and the housing 230 .

The sleeve 260 is a cylindrical structure with both ends open, and is installed to be movable up and down in the axial direction with respect to the housing 230 . The sleeve 260 may slide upward with respect to the housing 230 to collect the powder brush 210 . The sleeve 260 may slide downward with respect to the housing 230 to open the powder brush 210 in use. In addition, the sleeve 260 is organically coupled between the housing 230 and the rotating body 240 to move up and down with respect to the housing 230 to rotate the rotating body 240 forward and reverse to transfer the discharge hole 232 and The hole 242 may be selectively communicated.

That is, the opening/closing unit 220 of this embodiment moves the sleeve 260 up and down, and may communicate or block the transfer hole 242 and the discharge hole 232 without a separate operation.

4, in this embodiment, a vertical groove 234 is formed on the inner circumferential surface of the housing 230, and a protrusion 262 engaged with the vertical groove 234 is formed on the outer circumferential surface of the sleeve 260 to protrude. can be The vertical groove 234 is formed to extend continuously from the upper end to the lower end of the housing 230 in the axial direction. At least one vertical groove 234 may be formed on the inner circumferential surface of the housing 230 . In this embodiment, two vertical grooves 234 are arranged at an angle of 180 degrees. The protrusion 262 is formed to protrude from the outer peripheral surface of the sleeve 260 in accordance with the formation position of the vertical groove 234 . The protrusion 262 may be formed under the sleeve 260 .

As the protrusion 262 is fitted and coupled to the vertical groove 234 , the rotation of the sleeve 260 with respect to the housing 230 is regulated. Accordingly, the sleeve 260 is not rotated with respect to the housing 230 and may only move up and down along the vertical groove 234 .

In the present embodiment, the structure in which the vertical groove 234 and the protrusion 262 are formed in the housing 230 and the sleeve 260, respectively, has been described, but the reverse structure is also applicable. For example, a vertical groove 234 is formed on the outer circumferential surface of the sleeve 260 and a protrusion 262 is formed on the inner circumferential surface of the housing 230 to be engaged with each other.

Looking at the coupling structure of the rotating body 240 and the sleeve 260, as shown in FIGS. 4 and 5, a cam groove 250 is formed on the outer peripheral surface of the rotating body 240, and a cam groove (250) is formed on the inner peripheral surface of the sleeve 260. A cam projection 264 engaged with the 250 may be formed to protrude.

The cam groove 250 is formed to extend continuously from the upper end to the lower end of the rotating body 240 in the axial direction. At least one cam groove 250 may be formed on the outer peripheral surface of the rotating body 240 . In this embodiment, two cam grooves 250 are arranged at an angle of 180 degrees.

The cam groove 250 may extend in the axial direction and be inclined with respect to the axial direction so that both ends are spaced apart along the circumferential direction. Accordingly, when the sleeve 260 slides up and down, the cam projection 264 of the sleeve 260 moves up and down along the cam groove 250 , and the rotating body 240 rotates forward and reverse with respect to the sleeve 260 .

In addition to the above structure, a structure in which the cam groove 250 is formed on the inner circumferential surface of the sleeve 260 and the cam protrusion 264 is formed on the outer circumferential surface of the rotating body 240 is also applicable. In this structure, when the sleeve 260 moves up and down, the rotating body 240 engaged with the cam groove 250 via the cam projection 264 rotates forward and reverse along the cam groove 250 .

In this embodiment, the cam groove 250 includes an inclined portion 252 formed to be inclined with respect to the axial direction, and a straight portion 254 extending along the axial direction extending from the inclined portion 252 to form both ends of the cam groove 250 . may include. The inclined portion 252 and the straight portion 254 are integrally formed with each other to form one cam groove 250 . Accordingly, in the process of the cam projection 264 passing the inclined portion 252 of the cam groove 250, the rotating body 240 rotates, and the cam projection 264 moves the straight portion 254 of the cam groove 250. When passing, when the rotating body 240 is stopped, only the sleeve 260 can move up and down.

In this way, by forming the straight portions 254 at both ends of the inclined portion 252, the rotational position of the rotating body 240 can be accurately set. That is, when the cam protrusion 264 reaches the straight part 254 of the cam groove, even if the sleeve 260 moves up and down further, the rotating body 240 is not rotated any more. Accordingly, regardless of the difference in the degree of vertical movement of the sleeve 260, the rotating body 240 may be rotated to a set position to maintain its state. Accordingly, the opening and closing of the discharge hole 232 is performed accurately.

In addition to the above structure, the cam groove 250 may have a structure formed in a spiral shape as a whole along the axial direction. Also in this structure, in the process of the cam projection 264 passing the cam groove 250, the rotating body 240 in which the cam groove 250 is formed rotates forward and reverse in a spiral form with respect to the sleeve 260 to open and close the discharge hole 232. can

In this embodiment, when the sleeve 260 is moved downward, the powder brush 210 is exposed, and the discharge hole 232 is opened to be in use. Conversely, when the sleeve 260 is moved upward, the powder brush 210 is wrapped and protected by the sleeve 260 , while the discharge hole 232 is blocked to block the discharge of the powder.

3, the sleeve 260 is further formed with an elastic piece 266 at the lower portion, and a locking groove 267 through which the elastic piece 266 is hooked on the upper portion of the rotating body 240 is further formed. can be The elastic piece 266 may be formed between the slits cut at the front end of the sleeve 260 to elastically adhere to the rotating body 240 .

The locking groove 267 is formed at a position corresponding to the position of the elastic piece 266 when the sleeve 260 is maximally raised, so that the elastic piece 266 can be caught in the locking groove 267 .

Accordingly, the sleeve 260 may be moved up and down in a state resiliently in close contact with the rotating body 240 by the elastic piece 266 . In addition, when the maximum rises, the sleeve 260 is fixed to the rotating body 240 while the elastic piece 266 is seated in the locking groove 267 . Therefore, the sleeve 260 can be fixed to the rotating body 240 in an elevated state, and when the cosmetic container is not in use, the discharge hole 232 blocking state according to the rise of the sleeve 260 can be stably maintained.

In addition, a stepped 268 is formed as an inner circumferential surface at the lower end of the sleeve 260 , and a flange 269 may protrude along the outer circumferential surface at the upper end of the rotating body 240 inserted into the sleeve 260 . Accordingly, when the sleeve 260 is moved upward, the step 268 of the sleeve 260 is caught on the flange 269 of the rotating body 240 to prevent the sleeve 260 from being separated from the rotating body 240 . be able to do

5 shows the opening and closing action of the discharge hole according to the elevation of the sleeve.

As shown, the rotating body 240 rotates forward and reverse according to the elevation of the sleeve 260 to open and close the discharge hole 236 .

The sleeve 260 can move only up and down with respect to the housing 230 in which the protrusion 262 is hung in the vertical groove 234 . In addition, the sleeve 260 is coupled to the rotating body 240 and the cam groove 250 and the cam projection 264 as a medium. The rotating body 240 is not moved vertically with respect to the housing 230 but is only rotatably coupled, so that only rotation is possible when the sleeve 260 moves up and down.

Accordingly, when the sleeve 260 is moved up and down, the rotating body 240 engaged with the cam protrusion 264 of the sleeve 260 through the cam groove 250 rotates with respect to the housing 230 . As the rotating body 240 rotates with respect to the fixed housing 230 , the position of the transfer hole 242 with respect to the discharge hole 232 is moved and the discharge hole 232 may be opened and closed.

That is, when the sleeve 260 is raised to the housing 230 , the rotating body 240 rotates in one direction so that the transfer hole 242 formed in the rotating body 240 is formed in the housing 230 of the discharge hole 232 formed in the housing 230 . misplaced in position. Accordingly, while the discharge hole 232 is blocked, the discharge of the powder is blocked.

Conversely, when the sleeve 260 is lowered from the housing 230 , the rotating body 240 rotates in the opposite direction. Accordingly, the transfer hole 242 formed in the rotating body 240 is moved to the position of the discharge hole 232 formed in the housing 230 . That is, as the rotating body 240 rotates with respect to the fixed housing 230 , the transfer hole 242 is aligned with the discharge hole 232 position and communicates with each other. Accordingly, as the discharge hole 232 is opened, the powder may be supplied to the powder brush 210 through the discharge hole 232 and the transfer hole 242 .

As described above, the opening/closing unit 220 of the present embodiment can open and close the discharge hole 232 by rotating the rotating body 240 by moving the sleeve 260 up and down. Therefore, a separate operation for opening and closing the discharge hole 232 is unnecessary, so that the user can use it more conveniently.

6 shows the structure of the air injection unit according to the present embodiment.

As shown, the air spray unit 300 is installed at the lower end of the container body 110 and sprays air toward the discharge hole 232 , so that the powder can be forcibly ejected to the brush unit 200 .

The air injection unit 300 of this embodiment is formed in the holder 310 installed at the open lower end of the container body 110, the cover 312 installed on the holder 310, the cover 312 and the container body (110) an air pipe 314 extending upward to transport air, a button 316 installed at the bottom of the holder 310 and protruding outward so that it can be pressed from the outside, an inner wall 311 of the holder 310 and An elastic member 318) installed between the buttons 316 to apply an elastic return force to the button 316, installed at the top of the air tube 314 to adjust the air pressure of the air tube 314 according to the button 316 operation. It may include a check valve 320 for spraying air into the discharge hole 232 of the container body 110 by being opened and closed.

In addition, the air injection unit 300 may further include a piston member 317 installed on the button 316 and resiliently in close contact with the inner circumferential surface of the holder 310 by having a skirt having an outer diameter extending upward.

The holder 310 may be detachably coupled to the lower end of the container body 110 . For example, a male screw and a female screw are formed at the lower end of the container body 110 and the lower end of the holder 310 to be screwed to each other.

A cover 312 is coupled to the upper end of the holder 310 . The cover 312 may cover the holder 310 to seal the inner space of the cover 312 . An air tube 314 is integrally formed on the upper end of the cover 312 . The air tube 314 communicates with the inner space of the holder 310 and extends vertically toward the discharge hole. Accordingly, when the button 316 is pressed, the air in the inner space of the cover 312 may be ejected toward the discharge hole through the air tube 314 .

A hole is formed at the bottom of the holder 310 to be coupled to the button 316 . A cylinder-shaped inner wall 311 to which the piston member 317 is closely adhered may be formed inside the holder 310 . The button 316 is inserted into the holder 310 and is installed to protrude to the outside through the hole of the holder 310 . A piston member 317 is installed inside the button 316 and moves like the button 316 . The piston member 317 is formed with a skirt portion having a gradually increasing diameter toward the upper portion and is in close contact with the inner wall 311 of the holder 310 . The piston member 317 may be formed of, for example, an elastic material such as rubber or silicone.

Accordingly, when the button 316 is pressed, the skirt portion of the piston member 317 is in close contact with the inner wall 311 of the holder to push the air in the inner space of the holder 310 to the air tube 314 .

An elastic member 318) is inserted into the inner space of the holder 310 and elastically installed between the button 316 and the cover 312. Accordingly, when the button 316 is pressed, the elastic member 318 is elastically compressed and an elastic return force is applied to the button 316 to restore the button 316 to its original state.

A check valve 320 is installed at the front end of the air pipe 314 .

The check valve 320 is a valve 320 that transfers the fluid in only one direction, and can transfer the fluid from the air pipe 314 to the discharge hole 232, and block the fluid transfer in the opposite direction. Accordingly, air is injected into the discharge hole by the check valve 320 , and the powder does not flow into the air pipe 314 through the check valve 320 .

In this embodiment, the check valve 320 is formed of an elastic material, the lower end is open and communicates with the air tube 314, and both surfaces extending to the upper side form a sharp horn shape that gradually decreases in thickness, and A slit-shaped cutting line 322 may be formed at the upper end to be in contact with each other.

The check valve 320 may be made of an elastic material so as to be deformable by elasticity. For example, the check valve 320 may be formed of a material such as rubber, silicone, or resin. The check valve 320 has its own elasticity, and when the external force is removed in a state elastically deformed by external pressure, it can be returned to its original state by its own elastic restoring force.

The check valve 320 may be opened and closed according to a change in internal pressure through the air pipe 314 to discharge air in one direction. That is, when the button 316 is pressed, when the internal pressure of the holder 310 increases, the cut line 322 of the front end of the check valve 320 is widened and opened. Accordingly, air from the air pipe 314 is injected toward the discharge hole 232 of the housing 230 through the check valve 320 .

Conversely, when the external force is removed from the button 316 , the pressure of the air tube 314 is lowered while the button 316 is returned to its original state. Accordingly, between the cut lines 322 of the front end of the check valve 320 are closely closed, and the powder outside the check valve 320 does not flow into the air tube 314 .

As such, by spraying air toward the discharge hole 232 through a simple structure, the powder in the container body 110 can be more smoothly discharged to the powder brush 210 through the discharge hole 232 and used.

Although exemplary embodiments of the present invention have been illustrated and described as described above, various modifications and other embodiments may be made by those skilled in the art. All such modifications and other embodiments are intended to be contemplated and included in the appended claims without departing from the true spirit and scope of the present invention.
