The pressing means 440 is a device for transmitting the external force of the user to the brush holding means 420 and includes a housing 441, a pressing member 443 and a pressing member 445.

The plunger 445 is moved in accordance with an external force applied in the first direction D1 while being accommodated in the brush support means 420 to move the brush support member 420 in the first direction D1, .

The pushing member 443 is moved in the first direction D1 and the second direction D2 while at least a part of the pushing member 443 is accommodated in the housing 441. One end 4433 is formed to be engageable with the pusher 445, And an external force of the user acts on the other end 4431,

More specifically, the plunger 445 has a rear end portion 4451 formed to be engageable with one end 4433 of the pushing member 443, a distal end portion 4455 contacting with the soling gripping piece 427 of the brush supporting means 420, And a stopper 4453 which moves through the housing 441. [

The rear end portion 4451 of the push rod 445 is engageable with the screw thread 4433A formed inside the one end 4433 of the pushing member 443 according to a screw coupling method. That is, the rear end 4451 of the push rod 445 and the one end 4433 of the pushing member 443 are separated from each other at the unlocking position and the rear end 4451 of the push rod 445 and the pushing member 443 One end 4433 can be coupled. With the above structure, the pressing member 443 can push the plunger 445 in the first direction D1 only in the unlocking position and the locking position.

That is, the pushing member 445 and the pushing member 443 according to one embodiment of the present invention are integrally combined as necessary so that an external force applied in the first direction D1 is transmitted to the solenoid member 427 So that the external force applied in the first direction D1 is not transmitted to the soled piece 427 as needed. Here, the former can be regarded as a situation when the user uses the nail polish, and the latter can be regarded as a situation when the user uses the nail polish.

For example, when the user uses the nail polish, the pushing member 443 is turned counterclockwise to engage the pushing member 443 with the push rod 445, and then pushes the pushing member 443 in the first direction D1, When the nail polish is stored for a long time, the pushing member 443 is turned clockwise to separate the pushing member 443 and the push rod 445 from each other The brush 429 can be prevented from being pulled out of the body portion 450 even if the pushing member 443 is pressed by an undesired external force. That is, even if the pressing member 443 is pressed as shown in Fig. 4, the brush 429 is not drawn out.

On the other hand, when the user rotates the pressing member 443 in a counterclockwise direction so as to engage the one end 142 of the pressing member 443 and the rear end 4451 of the pressing rod 445 It is necessary to fix the plunger so that the plunger 445 does not follow it.

To this end, the intermediate portion 4453 of the plunger 445 may have a different cross-sectional shape than the tip portion 4455 or the rear end portion 4451.

For example, the distal end portion 4455 and the rear end portion 4451 of the pusher 445 may have a circular sectional shape, and the intermediate portion 4453 may have a polygonal or elliptical sectional shape. In addition, the cross-sectional shape of the hole 4415 formed at the tip end of the housing 441 through which the stopper of the push rod 445 is passed may also be polygonal or elliptical.

As described above, the middle portion 4453 of the push rod 445 is a component moving through one side of the housing 441, and the housing 441 is connected to the housing receiving portion 421 of the brush support means 420 The stopper portion 4453 of the pusher 445 is formed into a polygonal or elliptical shape so that the pusher member 443 connected to the pusher 445 is rotated, So that the rear end portion 4451 of the push rod 445 can be coupled to the screw thread 4433A formed at one end 4433 of the pushing member 443 in a screwing manner without being rotated together with the pushing member 443 do.

Although the pressing member 443 is described as being coupled with the push rod 445 in the counterclockwise direction in the above description, it is possible to form the push rod 4443A so that the pushing member 443 can be engaged with the push rod 445 Of course it is.

According to one embodiment of the present invention, the middle portion 4453 of the pusher 445 includes a protruding region 4454 protruding from one region, and the outer surface of the protruding region 4454 and the inner surface of the hole 4415 Has a tapered shape in a direction to be inserted into the hole 4415.

Figs. 3A and 3B are enlarged views of a part of the plunger 445 and the housing accommodating portion 421. Fig. Referring to FIG. 3A, a protruding region 4454 having a tapered shape is inserted in the hole 4415 in an interference fit. The protruding region 4454 inserted once is caught by the distal end of the hole 4415 as shown in B of FIG. 3 so that the push rod 445 is moved away from the housing receiving portion 421 in the second direction D2 As shown in Fig.

According to one embodiment of the present invention, the extension / retraction part 423 of the brush support means 420 is moved in the first direction 422 while the housing accommodation part 421 is fixed to the container stopper 470, (D1) and the second direction (D2). The stretchable and contractible portion 423 may be formed of a flexible material. 2, it is assumed that the stretchable and contractible portion 423 has a wrinkled shape, but various structures for stretching and shrinking operations may be applied.

The push rod 445 goes out of the rod insertion cylinder 440 while being received in the housing receiving portion 421 and the stretchable and contractible portion 423 and is not directly exposed to the manicure liquid. 3 and 4, if the pusher 445 moves in and out of the rod insertion tube 440 without the configuration of the housing receiving portion 421 and the stretching portion 423, the brush 429 protrudes outside the body portion 450 The nail polish 445 is brought into contact with the nail polish liquid. When the brush 429 is received back into the body portion 450, the pusher 445 is moved into the housing 441. At this time, the nail polish liquid adhering to the intermediate portion 4453 of the plunger 445 can be exposed to air and hardened. In this case, the intermediate portion 4453 of the plunger 445 may not be able to smoothly move the hole 4451 formed at the distal end of the housing 441.

That is, the stretchable and contractible portion 423 expands and contracts in accordance with the movement of the plunger 445 in the first direction D1 and the second direction D2 while preventing the plunger 445 from being directly exposed to the nail polish liquid, ) Can be smoothly moved.

According to one embodiment of the present invention, the cosmetic container 400 provides a sealing structure to protect the manureure liquid which is easily hardened by contact with outside air.

2 to 4, the housing receiving portion 421 can be fixed in an interference fit manner between the housing 441 and the container stopper 470, and the housing receiving portion 421 can be fixed to the housing 441 and the container stopper 470, the brush support means 420 can be expanded and contracted in the first and second directions. The outer diameter of the housing 441 corresponds to the inner diameter of the housing receiving portion 421 and the inner diameter of the container cap 470 corresponds to the outer diameter of the housing receiving portion 421. [

According to an embodiment of the present invention, the elastic member 480 is accommodated in the rod insertion tube 440 and is placed along the outer peripheral surface of at least a part of the tongue piece 427 and is moved in the first direction D1, (427) in the second direction (D2). Accordingly, when the external force in the first direction D1 applied to the other end 4431 of the pressing member 443 is removed, the tongue piece 427 can move in the second direction D2, The sole 429 that has passed through the opening 440 may also move in the second direction D2 and enter the space in the tip end 412 of the rod insertion tube 440 again.

At this time, as described below, the manicure liquid is present in the space portion in the tip end portion 412 of the rod insertion cylinder 440, so that the brush 429 is impregnated with the manicure liquid, and the user presses the pushing member 443 again You can apply the nail polish solution to the desired position by pressing the brush.

According to one embodiment of the present invention, for securing the elastic member 480, the ring-shaped member 428 may be inserted and fixed between the tongue piece 427 of the brush support means 420 and the stretchable and contractible portion 423 The guide member 418, which will be described below, may be utilized to fix the elastic member on the opposite side of the ring-shaped member 428. [

That is, one end of the elastic member 480 may be fixed to the guide member 418 and the other end may be fixed to the ring-shaped member 428.

The liquid inflow hole 4161 formed in the rod insertion tube 440 is inserted into the middle region of the rod insertion tube 440 in a state where the nail polish liquid existing in the body 454 of the body portion 450 The meniscus liquid flowing into the main body 454 or the manicure liquid present in the middle area 416 is flowed into the main body 454.

As described above, the bar supporting means 420 and the elastic member 480 are accommodated in the bar insertion cylinder 440, and the expansion and contraction portion 423 is supported by the bar insertion cylinder 440 Or in the second direction D2 within the bar insertion cylinder 440 by the elastic member 480. The elastic member 480 is provided in the bar insertion cylinder 440 in the first direction D1.

At this time, the pressure in the rod insertion cylinder 440 may be increased according to the expansion and contraction of the expandable and contractible portion 423. According to the embodiment of the present invention, the number of the liquid inflow holes 4161, the overall pressure in the container 400 can be kept constant.

Further, when the user pushes the pushing member 443 to expand and contract the stretchable and contractible portion 423, the nail polish liquid in the container 400 is evenly mixed, thereby preventing the hardening of the nail polish liquid.

Referring to FIG. 2 again, in order to provide a more comfortable operation of the user in using the manicure, the other end 4431 of the pressing member 443 according to an embodiment of the present invention is slidable in a direction transverse to the first direction D1 The engaging member 447 can be engaged.

The engaging member 447 is slid in the direction transverse to the first direction D1 at a position where the pushing member 443 has completed the sliding movement in the first direction D1, that is, at the position when the user uses the nail polish Whereby one end of the engaging member 447 is caught by the rim of the container stopper 470 and movement of the pushing member 443 in the second direction D2 can be suppressed.

Accordingly, the user does not have to continue pushing the pushing member 443 to use the nail polish, and can easily work after fixing the pushing member 443 by using the engaging member 447. [

On the other hand, the user can return the latching member 447 to the original position in order to again apply the nail polish liquid to the brush 429. In this case, the elastic piece 480 described above causes the brush piece 427 to rotate in the second The brush 429 can be returned to the direction D2 and then the brush 429 can enter the space inside the tip end 412 of the rod insertion tube 440 and be impregnated with the nail polish liquid.

5 is a view showing a process of introducing a manicure liquid into the tip end 412 of the rod insertion cylinder 440 according to an embodiment of the present invention.

5A, the bristle piece 427 of the brush support means 420 is movable in the first direction and the second direction while being inserted into the guide member 418. As shown in FIG.

At this time, the guide member 418 can guide the sliding movement of the tongue piece 427 while being fixed between the tip end portion 412 of the rod insertion tube 440 and the middle region 416. As described above, the movement of the tongue piece 427 can be performed by the operation of the pusher 445 and the pushing member 443.

A guide hole 4181 is formed in the guide member 418 so that the sliding movement of the tongue piece 427 can be guided by the guide member 418. [

Further, a narrowed portion 4273 whose outer diameter is reduced from one area of the tongue piece 427 may be formed on the tongue piece 427. [ The narrowed portion 4273 may be formed by reducing the outer diameter of the tongue piece 427 or by forming a groove in the tongue piece 427. The outer diameter of the narrowed portion 4273 is formed to be smaller than the inner diameter of the guide hole 4181 formed in the guide member 418. [

More specifically, as shown in Figs. 5A to 5D, the narrowed portion 4273 moves together with the movement of the tongue piece 427 in the first direction D1 to enter the guide member 418, The liquid material 40 received in the narrowed portion 4273 flows into the space as the neck portion 4273 enters the space portion in the tip end portion 412 of the rod insertion tube 440. [

According to an embodiment of the present invention, the lower region of the narrowed portion 4273 is tapered in the first direction so that the liquid material 40 accommodated in the narrowed portion 4273 can smoothly flow down to the space portion.

With this structure, when the user presses the pushing member 443 for the nail polish operation, the nail polish liquid present in the middle region 416 of the rod insertion cylinder 440 can be stably filled into the space in the tip end 412 After the operation, the brush 429 with the nail polish wiped is retracted back into the space in the distal end 412 and impregnated with the filled nail polish liquid.

Further, when the user presses the pushing member 443 for the nail polish operation, the pushing member 443 can be pressed once more when the nail polish liquid adhered to the brush 429 is small. At this time, So that the brush 429 can be impregnated with a sufficient amount of the manicure liquid.

That is, each time the pushing member 443 is pushed by the user, the user can adjust the amount of the liquid material desired by the user by flowing into the space portion in the tip end portion 412 by the liquid material contained in the narrowed portion 4273, It is possible to prevent a large amount of the liquid material from flowing into the space portion in the space.

The cap 490 is coupled to the distal end portion 452 of the body portion 450 so that the distal end portion 412 of the rod insertion tube 440 at which the brush 429 is impregnated with the nail polish liquid is blocked from the outside air .

Conventionally, when applying a manicure, the bottle is usually placed next to the user, so there is a danger that the bottle may fall due to carelessness, and when the bottle is put into the bottle after the use, the nail polish may be scratched There is the inconvenience of having to apply nail polish again.

In addition, since the nail polish solution contains a thinner component, the nail polish is easily volatilized unless the stopper is completely sealed due to its high volatility due to the nature of the product, and there is a problem that the nail polish liquid in the container hardens or deteriorates to lose its function as a product.

However, according to the present invention, it is possible to perform the manicure work at a desired position by pulling out the brush impregnated in the nail polish liquid present at the tip end portion of the rod insertion cylinder from the rod insertion cylinder by pressing the pressing member, So that the external force can not be transmitted by separating the pressing member from the plunger so as to prevent the sol from being pulled out and damaged from the rod insertion cylinder by an undesired external force. Further, since the pressing member is accommodated in the main body portion during the manicure work, there is aesthetic sense of beauty. Further, the cosmetic container according to the present invention is a shape that can be stored by closing the cap after use, and is a product including a good design element together with a function of protecting the brush.

Further, even if the stretching operation of the brush holding means is repeated in the bar insertion cylinder, the pressure in the container is evenly dispersed so that the liquid does not leak out of the container, thereby improving the stability of the container.
