1 to 8, the cosmetic container 1000 is a dial 100, a container part 200, a piston arm 300, a piston 400, a transport pipe 500, a connection part 600, a discharge part It may include a 700, the coating unit 800 and the cover portion 900.

The dial 100 is provided on the upper side of the container portion 200 and receives rotational force from a user, so that it can rotate relative to the container portion 200. Specifically, the first stepped portion 110 is formed in the circumferential direction on the outer circumferential surface of the lower portion of the dial 100, and correspondingly, the second stepped portion 220 is formed on the inner circumferential surface of the upper portion of the container 200, and the dial ( The first stepped portion 110 of 100) may be mounted on the second stepped portion 220 of the container portion 200. Through this, the dial 100 may be disposed inside the upper portion of the container unit 200.

In addition, the dial 100 is disposed inside the upper portion of the container portion 200, at least a portion of the dial 100 may be exposed to the outside through the opening portion 210 formed in the container portion 200. That is, the user can rotate the dial 100 while holding the lower end of the container part 200 with one hand, so that the cosmetic material accommodated in the container part 200 is discharged through the discharge part 700. Can.

In particular, the dial 100 is not coupled to the container portion 200 from the outside of the container portion 200, but in that it rotates in a state disposed inside the container portion 200, the stable counterpart of the dial 100 You can make it possible to rotate.

On the other hand, a first thread may be formed on at least a portion of the inner circumferential surface of the lower end portion of the dial 100, and at least a portion of the outer circumferential surface of the piston arm 300 inserted into the lower end portion of the dial 100 may also correspond to the first thread. 2 Threads may be formed. Through this, the dial 100 and the piston arm 300 are screwed to allow the piston arm 300 to move up and down according to the rotation of the dial 100. This will be described in more detail below.

The container 200 may contain cosmetic material therein. Here, the cosmetic material may be applied and/or absorbed on the skin of a user for purposes such as beauty, and may be a liquid cosmetic material, but is not limited thereto.

In addition, the container unit 200 serves as a reference for rotation of the dial 100, and may be provided to allow the dial 100 to rotate relative to the upper side. In detail, the dial 100 is disposed to be rotatable relative to the inside of the upper portion of the container portion 200, so that at least a portion of the dial 100 is exposed to the outside through the opening portion 210, so that the rotational force of the user is the container. It can be transmitted to the dial 100 disposed inside the unit 200. At this time, the opening portion 210 may be formed by at least a portion of the upper portion of the container portion 200 passing through in the longitudinal direction of the container portion 200, and may be configured as at least one.

On the other hand, the dial 100 is disposed to be rotatable relative to the container portion 200, the dial 100 and the container portion 200 may be interlocked with each other to guide the rotation direction of the dial 100. Specifically, the dial 100 may be rotated only in the forward direction, and accordingly, the piston arm 300 and the piston 400 may be lowered. That is, by preventing the rotation of the dial 100 in the reverse direction, it is possible to prevent the piston arm 300 and the piston 400 from rising.

To this end, at least one guide groove 230 may be continuously formed in the circumferential direction on the inner circumferential surface of the container unit 200. The guide groove 230 may be continuously formed in the longitudinal direction of the container unit 200 from the second stepped 220, and may have a first inclined surface 232 and a second inclined surface 234, respectively. In response to this, at least one elastic piece 120 that can be bent in the inner direction may be formed on the outer peripheral surface of the lower end of the dial 100. In one region of each elastic piece 120, guide projections 130 may be formed to protrude in the longitudinal direction corresponding to the guide grooves 230, and each guide projection 130 is provided with a third inclined surface 132. 4 may have an inclined surface (134).

In the guide groove 230, the first inclined surface 232 and the second inclined surface 234 are formed in opposite directions, and may have different inclinations from each other. For example, the first inclined surface 232 may include a second inclined surface ( 234). Similarly, the third inclined surface 132 and the fourth inclined surface 134 are formed in opposite directions, and may have different inclinations from each other. For example, the third inclined surface 132 may have a gentle slope compared to the fourth inclined surface 134. Preferably, the second inclined surface 234 and the fourth inclined surface 134 may be perpendicular to the inner peripheral surface of the container portion 200 and the outer peripheral surface of the dial 100, respectively. Here, the inclination of the inclined surface may be defined as being gentle when it is close to the tangent of the circumference, whereas it may be defined as being steep when it is near the normal of the column.

Meanwhile, the elastic piece 120 of the dial 100 may be formed to be bendable to the inside of the dial 100 by cutting at least a partial area of the lower end of the dial 100. In FIG. 4, the upper end of the elastic piece 120 is integral with the dial 100, and the left, right, and lower ends of the elastic piece 120 are cut and penetrated, so that the elastic piece 120 is the length of the dial 100. Although shown as being formed in a direction, this is exemplary, and various configurations may be applied according to an embodiment to which the present invention is applied. For example, the right side of the elastic piece 120 is integrally formed with the dial 100, and the upper, lower, and left sides are cut through, or alternatively, the left side of the elastic piece 120 is integral with the dial 100. Since the upper, lower and right sides are cut and penetrated, the elastic piece 120 may be formed in the circumferential direction of the dial 100.

When the dial 100 is disposed inside the upper part of the container part 200, the guide protrusion 130 of the dial 100 may be inserted into the guide groove 230 of the container part 200. In this state, when the dial 100 rotates in the forward direction, the third inclined surface 132 of the elastic piece 120 likewise comes into contact with the first inclined surface 232 of the container portion 200 having a gentle inclination, A part of the rotational force in the forward direction by the first inclined surface 232 and the third inclined surface 132 may be converted into a force that presses the elastic piece 120 inward. Accordingly, by bending the elastic piece 120 to the inside of the dial 100, the third inclined surface 132 of the elastic piece 120 rides over the first inclined surface 232 of the container portion 200, Forward rotation can be performed.

Conversely, when the dial 100 is to rotate in the reverse direction, the fourth inclined surface 134 of the elastic piece 120 may contact the second inclined surface 234 of the container part 200. Since the second inclined surface 234 and the fourth inclined surface 134 have relatively steep inclinations, the rotational force in the reverse direction by the second inclined surface 234 and the fourth inclined surface 134 presses the elastic piece 120 inward. Therefore, since the fourth inclined surface 134 of the elastic piece 120 does not ride on the second inclined surface 234 of the container part 200, as a result, reverse rotation is not achieved. .

In particular, when the dial 100 rotates in the forward direction, the user must feel the rotational load because the user has to apply a force for the elastic deformation of the elastic piece 120, and the elastic piece 120 is restored after the elastic deformation. The first inclined surface 232 of the guide groove 230 and the third inclined surface 132 of the guide protrusion 130 collide with each other to make a'click' sound, through which the user rotates through the rotating load and the sound You can recognize and control.

On the other hand, the guide groove 230 of the container portion 200 is formed of at least one, at least one that does not directly contact the dial 100 (especially, the lower region of the first stepped 110 of the dial 100) By including the inner recessed area, friction that may occur when the dial 100 is rotated is reduced or eliminated, so that the dial 100 can be smoothly rotated.

Depending on the embodiment, at least a portion of the container portion 200 may be formed of a transparent or translucent material. Through this, the user can operate the dial 100 while checking the movement of the piston 400 inside the container 200 or the remaining amount of the cosmetic.

At least a portion of the piston arm 300 is disposed inside the dial 100, and can be moved up and down by rotation of the dial 100. Specifically, the second thread corresponding to the first thread formed on the inner circumferential surface of the lower end portion of the dial 100 is formed on at least part of the outer circumferential surface of the piston arm 300, so that the dial 100 and the piston arm 300 are screwed to each other can do. At this time, when the dial 100 is rotated, the piston arm 300 does not rotate together, and is fixed to rotate, so that the piston arm 300 may move up and down by rotation of the dial 100. As will be described in more detail below, the transfer pipe 500 may be inserted into the piston arm 300 to prevent synchronous rotation of the piston arm 300 relative to the dial 100.

Piston 400 is disposed inside the container portion 200, the outer circumferential surface is in close contact with the inner surface of the container portion 200, the inner circumferential surface can be in close contact with the outer surface of the transfer pipe 500. Piston 400 is coupled to the lower portion of the piston arm 300, it is possible to move up and down with the piston arm 300. That is, when the piston arm 300 descends due to the rotation of the dial 100, the piston 400 descends together to pressurize the cosmetic contained in the lower side. The pressurized cosmetic may be discharged to the outside by moving through the transport pipe 500. The piston 400 may be formed of a material having elasticity, such as rubber or silicone, in order to improve the adhesion between the inner surface of the container part 200 and the outer surface of the transfer pipe 500. However, this is exemplary, and may be formed of various materials according to embodiments to which the present invention is applied.

The transfer pipe 500 is disposed inside the container portion 200 to transfer the cosmetic material accommodated under the container portion 200 to the upper side, and the transfer flow path so that the cosmetic can move inside the transfer pipe 500 ( 510), the guide portion 520 formed on at least one area of the outer surface of the transfer pipe 500 and the support portion 530 formed on the upper end of the transfer pipe 500 may be included.

The transfer passage 510 is formed in the longitudinal direction of the container part 200 inside the transfer pipe 500 to define a transfer path of the cosmetic. The transport passage 510 may include a first communication hole 512 through which the cosmetic material accommodated in the container part 200 flows downward, and a second communication hole 514 through which the cosmetic material is discharged upward. The first communication hole of the transport flow path 510 may be formed to be close to the bottom or bottom surface of the container unit 200 so as not to leave the remaining amount of the cosmetic material. In addition, as shown, the lower end of the transfer pipe 500 is opened in the lateral direction, so that the cosmetic material may be introduced into the first communication hole 512 through the lateral direction.

The elevating guide portion 520 may prevent the relative rotation of the piston arm 300 to guide the elevating of the piston arm 300. That is, even if the dial 100 is rotated, the piston arm 300 may be prevented from rotating, so that the piston arm 300 may move up and down.

Specifically, the elevating guide portion 520 may be formed in a longitudinal direction on one region of the outer surface of the transfer pipe 500, and may have a cross-section of the outer surface to be non-circular. Corresponding to this, the inside of the piston arm 300 is formed with a through portion 310 into which the elevating guide portion 520 can be inserted, the through portion 310 is also non-circular, like the elevating guide portion 520 It can be formed as.

As such, the piston arm 300 and the transfer pipe 500 may be prevented from rotating relative to each other by the through portion 310 and the elevating guide portion 520 formed in a non-circular shape (that is, the piston arm 300 ) To be synchronously rotated with the transfer pipe 500 ), so that the piston arm 300 can be rotated and separated with respect to the rotation of the dial 100. In addition, since the dial 100 is screw-defected with the piston arm 300 inserted into the inside, and the vertical movement is prevented by the connecting portion 600 and the container portion 200, the dial 100 has a piston arm ( Rather than ascending and descending based on 300), the piston arm 300 may be moved up and down along the elevating guide portion 520 through rotation of the dial 100.

That is, when the user grips the container portion 200 and rotates the dial 100, the dial 100 rotates with the vertical movement fixed, and the piston arm 300 screwed with the dial 100 ) Is rotated and separated from the rotation of the dial 100 by the elevating guide portion 520 of the transfer pipe 500, so that the rotational movement of the dial 100 is converted to vertical movement of the piston arm 300 to be moved up and down. Can.

On the other hand, the through portion 310 of the piston arm 300 is formed in a non-circular shape, like the elevating guide portion 520, the area 312 and the elevating guide portion 520 that comes into contact with the elevating guide portion 520. And an area 314 spaced apart from each other. This is to reduce the contact surface with the transfer pipe 500 disposed in the through part 310, so that the piston arm 300 can move up and down more smoothly.

The support part 530 is formed on the upper end of the transfer pipe 500 (especially, the upper side of the second communication hole 514), and is coupled to the discharge part 700 on the upper side, and on the connection part 600 on the lower side. By being supported by, the transport tube 500 can be stably placed in the cosmetic container 1000.

Specifically, the support part 530 includes a locking jaw 532 formed to protrude in the circumferential direction so that the transfer pipe 500 is mounted on the upper end of the connection part 600; A receiving portion 534 in which the discharge adjusting portion 720 is accommodated by being concavely recessed to communicate with the transfer passage 510 from the inside of the locking jaw 532; And an engaging portion 536 formed to extend above the locking jaw 532 and engaged with the inner side of the discharge head 710.

The receiving portion 534 may communicate with the second communication hole 514, and cosmetic may be introduced, and a space sufficient for the discharge adjusting portion 720 to be disposed and operated may be formed. In addition, the transfer pipe 500 is disposed inside the connection portion 600, so that the shaking or departure of the transfer pipe 500 does not occur, the receiving portion 534 has an outer diameter corresponding to the through hole of the connection portion 600 Can have In addition, the engaging portion 536 is formed to protrude upward, in close contact with the inner surface of the discharge head 710 of the discharge portion 700, a locking groove is formed in the circumferential direction, formed on the inner surface of the discharge head 710 The locking projections can be fitted.

The connection part 600 is coupled to the upper end of the container part 200 on the lower side, and coupled to the discharge part 700 on the upper side, so that the transfer pipe 500 is inserted and disposed inside.

Specifically, a locking jaw 610 protruding in a circumferential direction is formed on an outer circumferential surface of the connecting portion 600 so that the locking jaw 610 is mounted on the top of the container 200. In addition, a coupling portion 620 extending downwardly is formed in one region of the bottom surface of the locking jaw 610, and when the locking jaw 610 is seated on the top surface of the container 200, the coupling portion 620 is a container It may be in close contact with the inside of the top of the portion 200. At this time, at least one locking protrusion is formed on the outer circumferential surface of the coupling portion 620, and a corresponding locking groove is formed on the inner circumferential surface of the upper end of the container portion 200, so that the locking protrusion fits into the locking groove, thereby connecting the part 600 Can be combined with the container portion 200.

As such, when the connection portion 600 is coupled to the top of the container portion 200, the bottom surface of the coupling portion 620 and the top surface of the dial 100 may be in contact or close. That is, the upper side of the dial 100 is supported by the connecting portion 600, and as described above, the lower side of the dial 100 is supported by the container portion 200, so that the dial 100 does not move up and down. , It can be stably rotated relative to the container portion 200.

A through hole that penetrates up and down may be formed inside the connection part 600. The transfer pipe 500 may be inserted and disposed inward through the through-hole, and in particular, at least a portion of the transfer pipe 500 (ie, the outside of the receiving portion 534) may correspond to the inner diameter of the through-hole, and thus the transfer pipe The 500 may be stably mounted on the connection part 600. In addition, on the upper side of the connection portion 600, a locking groove may be formed along the circumferential direction, so that the discharge head 710 can be coupled to the connection portion 600.

Although the connection part 600 is shown with the transport pipe 500 as a separate configuration, this is an example, and according to an embodiment to which the present invention is applied, the connection part 600 and the transport pipe 500 may be implemented as one configuration. It might be.

The discharge part 700 is disposed at the upper end of the connection part 600 and is for discharging the cosmetic material transferred along the transport flow path 510 by the descending of the piston 400, the discharge head 710 and the discharge control part ( 720).

The discharge head 710 may communicate with the transfer pipe 500 to discharge cosmetic material, and may be combined with the transfer pipe 500 to the inner top, in addition to the top of the connection portion 600 to the inner bottom. To this end, the discharge head 710 may be formed with a discharge path 712 communicating with the second communication hole 514 and providing a path for the cosmetic to move.
