Description

  The present invention relates to a cosmetic container, and more particularly to a cosmetic container in which the discharge of cosmetics can be adjusted more easily by rotating a dial.

  In general, cosmetics are roughly classified into solid, powdery and liquid forms, and various containers are used depending on the form of the cosmetic. Nowadays cosmetic products such as foundations or lipsticks are supplied in the form of gels or liquids which are not powdery or solid. Conventionally, a tube container or a pump container is often used to store such liquid cosmetics.

  In such a tube container or pump type container, when squeezing the tube or pressing the pump to discharge the cosmetic material, it is not easy to adjust so that the desired amount of the cosmetic material is discharged, and It was not easy and inconvenient to use all the remaining cosmetics.

  In order to solve this, a rotary discharge type cosmetic container has been developed and used. This allows the user to rotate the container to push or discharge the stored cosmetic material by moving the piston up or down. However, in the conventional rotary discharge type cosmetics, when the user performs a rotary operation, it is not easy to estimate how much the piston has moved, and it is difficult to adjust the cosmetic to be discharged in a desired amount.

  Further, in the conventional rotary discharge type cosmetics, generally, the rotation operation part is located at the lower end of the container, and in order for the user to discharge the cosmetics, the body part of the container is grasped by one hand and rotated by the other hand. Since the operation part has to be rotated, it is inconvenient to use cosmetics while holding the hand mirror with one hand.

  Therefore, a cosmetic container capable of solving such a problem is required.

  The present invention is intended to solve the above problems, and an object of the present invention is to provide a cosmetic container in which the discharge of cosmetics can be adjusted more easily by rotating a dial.

  The technical problem of the present invention is not limited to the technical problem mentioned above, and other technical problems not mentioned will be apparently understood by those skilled in the art from the following description.

  According to one embodiment of the present invention, a cosmetic container is provided. The container is a dial to which a rotational force is applied by a user, a container part that accommodates cosmetics on the lower side and the dial is relatively rotatably provided on the upper side, and is arranged inside the container part. A piston arm that moves up and down by relative rotation of the dial with respect to the container part, a piston that is arranged so as to be in close contact with the inner wall of the container part, and that is coupled to the lower part of the piston arm and moves up and down together with the piston arm; A transfer pipe disposed inside and having a transfer passage formed therein in the longitudinal direction of the container for transferring the cosmetic, wherein the relative rotation of the dial lowers the piston arm and the piston. When the cosmetic material is pressed by the above, the cosmetic material flows into the lower portion of the transfer pipe and is discharged through the transfer passage.

  Preferably, an elevating guide part having a non-circular cross section is formed in a region of the transfer pipe, and a penetrating part corresponding to the elevating guide part is formed inside the piston arm. By inserting the elevating guide part into the penetrating part, it is possible to form an elevating guide part for guiding the up and down movement of the piston arm while preventing the piston arm from rotating during the relative rotation of the dial.

  Further, preferably, screw portions corresponding to each other are formed on an inner peripheral surface of the dial and an outer peripheral surface of the piston arm, and the dial and the piston arm can be screwed with each other.

  Further, preferably, at least one opening is provided in an upper part of the container in a longitudinal direction, and the dial is arranged inside an upper part of the container in which the opening is formed. The part can be exposed to the outside.

  Also, preferably, a locking step protruding in the circumferential direction and applied to the upper end surface of the container section, and extending downward from one region of the bottom surface of the locking step and tightly coupled to the inside of the upper end of the container section. A connection part may be further formed, and a connection part may be formed on the inside of which at least a part of the transfer tube is inserted.

  Further, preferably, a first step portion is formed in a circumferential direction on a lower outer peripheral surface of the dial, and a second step portion corresponding to the first step portion is formed on an upper inner peripheral surface of the container portion. The dial can be disposed on the inner upper portion of the container portion by the first step portion being in contact with the second step portion.

  Further, preferably, the upper end of the dial is supported by the bottom surface of the coupling part, and the lower end of the dial is supported by the second step part of the container part, thereby preventing the dial from moving up and down.

  Further, preferably, a guide groove is formed on the inner peripheral surface of the container portion, and at least one elastic piece bendable inward is formed on the outer peripheral surface of the lower end portion of the dial, and a region of the elastic piece is formed. A guide protrusion corresponding to the guide groove is provided on the outer side of the guide groove, and the guide groove and the guide protrusion are formed to have different inclined surfaces and elasticity depending on the rotating direction of the dial. It is possible to guide the forward rotation of the dial and prevent the backward rotation.

  Preferably, the guide groove is formed with a first inclined surface and a second inclined surface in opposite directions, and the guide protrusion is formed with a third inclined surface and a fourth inclined surface in opposite directions. Each of the first inclined surface and the third inclined surface may have a gentler inclination than the second inclined surface and the fourth inclined surface.

  Also, preferably, when the forward rotation is applied to the dial, the first inclined surface and the third inclined surface are in contact with each other, and the elastic piece is bent inward so that the forward direction of the dial is increased. When the dial is rotated and the reverse rotation is applied to the dial, the second inclined surface and the fourth inclined surface may contact each other to prevent the reverse rotation.

  Further, preferably, a discharge head that is respectively coupled to the connecting portion and the transfer pipe and has a discharge path through which the cosmetic is discharged, and a discharge adjustment that opens and closes a communication hole through which the cosmetic flows into the discharge head. A discharge part including a part may be further included.

  Further, preferably, the discharge adjusting portion is an elastic member supported by an inner bottom surface of the discharge head and exerting an elastic force downward, and an opening / closing member which is pressed downward by the elastic member to seal the communication hole. The opening / closing member can open the communication hole by the discharge pressure of the cosmetic material due to the rotation of the dial.

  Further, preferably, at least a part may be housed on the upper side of the ejection head and may further include an application unit for applying the cosmetic material exhaled through the ejection path to the skin.

  According to the present invention, when the dial is rotated, the cosmetic material in the container is pushed out and discharged while the piston descends, so that the cosmetic material can be easily and minutely discharged and adjusted by rotating operation. Since the piston descends while being in close contact with the inner wall of the container, the cosmetic in the container can be used without being left behind.

  Further, according to the present invention, since the dial is arranged on the upper side of the cosmetic container, it is not necessary to operate the cosmetic container with both hands. By expelling, the convenience of operation can be improved.

  Further, according to the present invention, since the dial is configured to be rotatable only in one direction, is easy to operate, and is configured to generate a rotational load and a specific sound, the user can rotate the dial (that is, , The degree of lowering of the piston) is easy to grasp.

  Further, according to the present invention, since the configuration necessary for the rotation and vertical movement of the piston fulfills the function of preventing the reverse rotation, a separate configuration for regulating the rotation direction is not included. Due to the simplification, economic advantages can be obtained during the manufacture of the container.

  Further, according to the present invention, by including the discharge adjusting portion including the sealing member, it is possible to prevent the internal cosmetics from leaking out during the storage of the cosmetic container, and adjust the discharge amount of the cosmetics together with the rotating operation. Can be done more easily.

  Further, according to the present invention, by providing a massage ball in the application section, the cosmetic can be applied to the skin using the massage ball.

  1 to 8, the cosmetic container 1000 includes a dial 100, a container part 200, a piston arm 300, a piston 400, a transfer pipe 500, a connecting part 600, a discharging part 700, an applying part 800 and a cover part 900. You can

  The dial 100 is provided on the upper side of the container part 200 and can rotate relative to the container part 200 by receiving a rotational force from a user. Specifically, a first step portion 110 is formed in a circumferential direction on an outer peripheral surface of a lower portion of the dial 100, and a second step portion 220 is correspondingly formed on an inner peripheral surface of an upper portion of the container portion 200. Accordingly, the first step 110 of the dial 100 can be supported by the second step 220 of the container 200. As a result, the dial 100 can be arranged inside the upper part of the container part 200.

  Also, the dial 100 is disposed inside the upper portion of the container part 200, and at least a part of the dial 100 can be exposed to the outside through an opening 210 formed in the container part 200. That is, the user can rotate the dial 100 while holding the lower end of the container part 200 with one hand, whereby the cosmetic material contained in the container part 200 can be discharged through the discharge part 700.

  In particular, the dial 100 is not coupled to the container part 200 outside the container part 200, but is rotated inside the container part 200, so that the dial 100 can be stably rotated relatively. ..

  Meanwhile, a first screw part may be formed on at least a part of the inner peripheral surface of the lower end of the dial 100, and a first screw part may be formed on at least a part of the outer peripheral surface of the piston arm 300 inserted inside the lower end of the dial 100. A second screw part corresponding to the one screw part may be formed. As a result, the dial 100 and the piston arm 300 are screwed together, whereby the piston arm 300 can be moved up and down by the rotation of the dial 100. This will be described in detail later.

  The container part 200 can store cosmetics therein. Here, the cosmetics can be applied and / or absorbed on the skin of the user for the purpose of beauty and the like, and are preferably liquid cosmetics, but are not limited thereto.

  Further, the container part 200 functions as a rotation reference of the dial 100, and the dial 100 may be provided on the upper side so as to be relatively rotatable. Specifically, the dial 100 is relatively rotatably disposed inside the upper part of the container part 200, and at least a part of the dial 100 is exposed to the outside through the opening part 210 so that the rotational force of the user can be increased. It can be transmitted to the dial 100 arranged inside. Here, the open part 210 may be formed by penetrating at least a part of the upper part of the container part 200 in the longitudinal direction of the container part 200, and may be composed of at least one.

  Meanwhile, the dial 100 is rotatably arranged with respect to the container part 200, and the dial 100 and the container part 200 can interlock with each other to guide the rotating direction of the dial 100. Specifically, the dial 100 can be rotated only in the forward direction, so that the piston arm 300 and the piston 400 can descend. That is, by preventing the dial 100 from rotating in the reverse direction, it is possible to prevent the piston arm 300 and the piston 400 from rising.

  Therefore, at least one guide groove 230 may be continuously formed in the inner peripheral surface of the container part 200 in the circumferential direction. The guide groove 230 may be continuously formed in the longitudinal direction of the container part 200 from the second step part 220, and may have a first inclined surface 232 and a second inclined surface 234, respectively. Corresponding to this, at least one elastic piece 120 that can be bent inward can be formed on the outer peripheral surface of the lower end portion of the dial 100. A guide ridge 130 may be provided in a longitudinal direction corresponding to the guide groove 230 in a region of each elastic piece 120. Each guide ridge 130 has a third inclined surface 132 and a fourth inclined surface. Can have 134.

  In the guide groove 230, the first inclined surface 232 and the second inclined surface 234 may be formed in opposite directions and have different inclinations. For example, the first inclined surface 232 may have a gentler inclination than the second inclined surface 234. Similarly, the third sloped surface 132 and the fourth sloped surface 134 may be formed in opposite directions and may have different slopes. For example, the third inclined surface 132 may have a gentler inclination than the fourth inclined surface 134. Preferably, the second inclined surface 234 and the fourth inclined surface 134 may be formed perpendicular to the inner peripheral surface of the container part 200 and the outer peripheral surface of the dial 100, respectively. Here, the inclination of the inclined surface can be defined as being gentle if it is close to the tangent of the circumference, and can be defined as steep if it is close to the normal of the circumference.

  On the other hand, the elastic piece 120 of the dial 100 can be formed to be bendable inside the dial 100 by cutting at least a partial region of the lower end of the dial 100. In FIG. 4, the upper end of the elastic piece 120 is integrated with the dial 100, and the left side, the right side, and the lower end of the elastic piece 120 are cut and penetrated to form the elastic piece 120 in the longitudinal direction of the dial 100. Although shown as an example, this is an exemplification, and various configurations are applicable depending on the 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 end, the lower end and the left side are incised and penetrated. Alternatively, the left side of the elastic piece 120 is integrally formed with the dial 100 and the upper end, The elastic piece 120 can be formed in the circumferential direction of the dial 100 by cutting and penetrating the lower end and the right side.

  If the dial 100 is disposed inside the upper portion of the container part 200, the guide protrusion 130 of the dial 100 can 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 comes into contact with the first inclined surface 232 of the container part 200 having the same gentle inclination, and thus the first inclined surface A part of the rotational force in the forward direction can be converted into a force for pressing the elastic piece 120 inward by the 232 and the third inclined surface 132. Accordingly, when the elastic piece 120 is bent inward of the dial 100, the third inclined surface 132 of the elastic piece 120 may move along the first inclined surface 232 of the container part 200 to rotate in the forward direction. it can.

  On the contrary, when the dial 100 tries to rotate in the opposite 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 a relatively steep inclination, the rotational force in the opposite direction becomes a force for pressing the elastic piece 120 inward by the second inclined surface 234 and the fourth inclined surface 134. Since it is not converted, the fourth inclined surface 134 of the elastic piece 120 cannot pass over the second inclined surface 234 of the container part 200, and consequently cannot rotate in the opposite direction.

  In particular, when the dial 100 rotates in the forward direction, the user has to apply a force to elastically deform the elastic piece 120, so that the user can feel a rotational load, and the elastic piece 120 may be 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 and make a clicking sound. Accordingly, the user can recognize and adjust the rotation operation by the rotation load and the sound.

  On the other hand, at least one guide groove 230 of the container part 200 is formed, and includes at least one inner recessed region that is not in direct contact with the dial 100 (in particular, the lower region of the first step 110 of the dial 100). It is possible to reduce or eliminate friction that may occur when the dial 100 rotates, and to make the dial 100 rotate smoothly.

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

  At least a part of the piston arm 300 is arranged inside the dial 100, and can be raised and lowered by rotating the dial 100. Specifically, the second screw portion corresponding to the first screw portion formed on the inner peripheral surface of the lower end portion of the dial 100 is formed on at least a part of the outer peripheral surface of the piston arm 300, whereby the dial 100 and the piston arm 300 are formed. The can be screwed together. Here, when the dial 100 rotates, the piston arm 300 is fixed without rotating together, so that the rotation of the dial 100 allows the piston arm 300 to move up and down. A transfer tube 500 may be inserted inside the piston arm 300 to prevent synchronous rotation of the piston arm 300 relative to the dial 100, as described in more detail below.

  The piston 400 is disposed inside the container part 200, and an outer peripheral surface thereof can be in close contact with an inner surface of the container part 200 and an inner peripheral surface thereof can be in close contact with an outer surface of the transfer pipe 500. The piston 400 is coupled to the lower part of the piston arm 300 and can be moved up and down together with the piston arm 300. That is, when the piston arm 300 is lowered by the rotation of the dial 100, the piston 400 is also lowered, and the cosmetic material accommodated on the lower side can be pressed. The pressed cosmetic can be discharged through the transfer pipe 500. The piston 400 may be formed of an elastic material such as rubber or silicon in order to improve the adhesion between the inner surface of the container part 200 and the outer surface of the transfer tube 500. However, this is merely an example, and may be formed of various materials according to the embodiments to which the present invention is applied.

  The transfer pipe 500 is disposed inside the container part 200, and is for transferring the cosmetic stored in the lower side of the container part 200 to the upper side, and the cosmetic can move inside the transfer pipe 500. Thus, the transfer channel 510, the elevating guide part 520 formed in at least one region of the outer surface of the transfer pipe 500, and the support part 530 formed at the upper end of the transfer pipe 500 may be included.

  The transfer channel 510 may be formed inside the transfer tube 500 in the longitudinal direction of the container part 200 to define a transfer path for cosmetics. The transfer channel 510 may include a first communication hole 512 on the lower side, into which the cosmetic material stored in the container part 200 flows, and a second communication hole 514, on the upper side, from which the cosmetic material is discharged. The first communication hole of the transfer channel 510 may be formed on the bottom surface of the container part 200 or near the bottom surface thereof so that the residual amount of the cosmetic material discharged is not left. Also, as shown in the figure, the lower end of the transfer pipe 500 may be opened laterally so that the cosmetic may flow laterally through the first communication hole 512.

  The elevating guide part 520 can prevent relative rotation of the piston arm 300 and guide the elevating and lowering of the piston arm 300. That is, even if the dial 100 rotates, the piston arm 300 does not rotate, and the piston arm 300 can move up and down.

  Specifically, the elevating guide part 520 may be formed in a region of the outer surface of the transfer tube 500 in the longitudinal direction, and the outer surface may have a non-circular cross section. Correspondingly, a penetrating part 310 into which the elevating guide part 520 can be inserted is formed inside the piston arm 300, and the penetrating part 310 can be formed in a non-circular shape like the elevating guide part 520.

  As such, the non-circular penetrating part 310 and the elevating guide part 520 may prevent the piston arm 300 and the transfer pipe 500 from rotating relative to each other (ie, the piston arm 300 may move relative to the transfer pipe 500). The rotation of the piston arm 300 can be separated from the rotation of the dial 100. Furthermore, since the dial 100 is screwed with the piston arm 300 inserted inside and the vertical movement is prevented by the connecting part 600 and the container part 200, the dial 100 does not move up and down with the piston arm 300 as a reference, The rotation of 100 may cause the piston arm 300 to move up and down along the lift guide 520.

  That is, when the user rotates the dial 100 while holding the container portion 200, the dial 100 rotates with the vertical movement being fixed, and the piston arm 300 screwed with the dial 100 is transferred to the transfer pipe 500. Since the rotation of the dial 100 is separated from the rotation of the dial 100 by the elevating guide part 520, the rotational movement of the dial 100 is converted into the vertical movement of the piston arm 300, so that the piston arm 300 can be moved up and down.

  Meanwhile, the penetrating part 310 of the piston arm 300 may be formed in a non-circular shape like the elevating guide part 520 and may include a region 312 contacting the elevating guide part 520 and a region 314 separated from the elevating guide part 520. This is to reduce the contact surface with the transfer pipe 500 arranged in the through portion 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 (in particular, on the upper side of the second communication hole 514). The support part 530 is connected to the discharge part 700 on the upper side and is supported by the connecting part 600 on the lower side. The transfer pipe 500 can be stably arranged in the cosmetic container 1000.

  Specifically, the support part 530 communicates with the transfer channel 510 inside the locking step 532 and the locking step 532, which is provided so as to project in the circumferential direction so that the transfer tube 500 is placed on the upper end of the connecting part 600. As described above, the container 534 may be recessed to house the discharge adjusting part 720, and the coupling part 536 may be extended above the locking step 532 and coupled to the inside of the discharge head 710.

  Cosmetics may flow into the accommodation portion 534 in communication with the second communication holes 514, and a sufficient space may be formed in which the discharge adjusting portion 720 is disposed and operated. In addition, the transfer pipe 500 is disposed inside the connection part 600, and the storage part 534 may have an outer diameter corresponding to the through hole of the connection part 600 so that the transfer pipe 500 does not shake or come off. In addition, the coupling portion 536 is provided on the upper side so as to be in close contact with the inner surface of the ejection head 710 of the ejection portion 700, an engagement groove is formed in the circumferential direction, and an engagement protrusion formed on the inner surface of the ejection head 710 is formed. Can be engaged.

  The connection part 600 may be arranged such that the lower side is connected to the upper end of the container part 200, the upper side is connected to the discharge part 700, and the transfer pipe 500 is inserted inside.

  Specifically, a locking step 610 that protrudes in the circumferential direction is formed on the outer peripheral surface of the connecting part 600, and the locking step 610 can be hooked on the upper end of the container part 200. Also, a coupling portion 620 extending downward is formed in a region of the bottom surface of the locking step 610. Therefore, if the locking step 610 is placed on the upper end surface of the container part 200, the coupling part 620 can be closely attached to the inside of the upper end of the container part 200. Here, at least one engaging protrusion is formed on the outer peripheral surface of the coupling portion 620, and an engaging groove corresponding to the engaging protrusion is formed on the inner peripheral surface of the upper end of the container part 200. The coupling part 600 may be coupled to the container part 200 by being engaged with.

  In this way, if the connecting part 600 is connected to the upper end of the container part 200, the bottom surface of the connecting part 620 and the upper end surface of the dial 100 can be brought into contact with or close to each other. That is, the upper side of the dial 100 is supported by the connecting part 600, and the lower side of the dial 100 is supported by the container part 200 as described above. It is possible to stably rotate relative to each other.

  Through holes may be vertically provided inside the connection part 600. The transfer tube 500 may be inserted and arranged in the inside through the through hole. In particular, by making at least a part of the transfer pipe 500 (that is, the outside of the accommodating part 534) correspond to the inner diameter of the through hole, the transfer pipe 500 can be stably applied to the connecting part 600. .. In addition, an engaging groove may be formed on the upper side of the connecting portion 600 along the circumferential direction, and thus the ejection head 710 may be connected to the connecting portion 600.

  Although the connection part 600 is shown as a separate structure from the transfer pipe 500, this is merely an example, and the connection part 600 and the transfer pipe 500 may have a single structure according to an embodiment to which the present invention is applied. It can also be embodied in.

  The discharge part 700 is disposed at the upper end of the connection part 600, and discharges the cosmetic material transferred along the transfer flow path 510 when the piston 400 descends. The discharge part 700 may include a discharge head 710 and a discharge adjustment part 720. it can.

  The discharge head 710 communicates with the transfer pipe 500 to discharge cosmetics, and the inner lower end may be connected to the upper end of the connection part 600, and the inner upper end may be connected to the transfer pipe 500. To this end, the ejection head 710 may be formed with an ejection passage 712 that communicates with the second communication hole 514 and provides a passage along which the cosmetic material moves.

  Also, two engaging protrusions may be provided on the inner surface of the ejection head 710 in the circumferential direction. Here, the engagement protrusion located on the upper side may be coupled with the engagement groove of the coupling portion 536 of the support portion 530. The lower engaging protrusion may be combined with the upper engaging groove of the connecting part 600.

  A mounting portion 714 may be formed on the inner bottom surface of the ejection head 710. The mounting portion 714 is formed such that an outer region of the discharge passage 712 is roughened, and supports the elastic member 724 of the discharge adjusting portion 720 housed therein, as will be described later in more detail. The member 724 can function as a reference point for generating an elastic force.

  An accommodating space 716 is formed inward at the upper end of the ejection head 710, and the coating part 800 can be accommodated and arranged in the accommodating space 716. However, this is an example, and the coating unit 800 and the accommodation space 716 may not be applied to the present invention depending on the embodiment.

  The discharge adjusting unit 720 is disposed inside the discharge head 710, and can open and close the second communication hole 514 of the transfer channel 510 to adjust the discharge of the cosmetic material. Specifically, the discharge adjusting unit 720 may open the second communication hole 514 when the dial 100 is rotated so that the cosmetic material is discharged to the outside through the discharge passage 712. In addition, when the dial 100 does not rotate, that is, in the normal storage state, the second communication hole 514 can be sealed to prevent the cosmetic material from leaking.

  To this end, the discharge adjusting unit 720 may include an opening / closing member 722 formed in a ball shape and having an inner diameter larger than that of the second communication hole 514, and an elastic member 724 that presses the opening / closing member 722.

  The elastic member 724 may be coupled to the mounting portion 714 on the outer side of the discharge passage 712 to exert an elastic force downward. Therefore, the opening / closing member 722 pressed downward by the elastic member 724 can seal the second communication hole 514.

  Further, when the dial 100 rotates and the cosmetic material rises along the transfer flow path 510 due to the lowering of the piston 400, the opening / closing member 722 rises due to the discharge pressure of the cosmetic material, and the second communication hole 514 opens. The cosmetic can be moved to the discharge path 712, and when the dial 100 stops rotating, the opening / closing member 722 can be pressed again by the elastic member 724 to seal the second communication hole 514. As a result, it is possible to prevent the cosmetic material from leaking when the rotational force is not applied to the dial 100.

  On the other hand, when the opening / closing member 722 is arranged above the second communication hole 514 to seal the second communication hole 514 and the user tries to rotate the dial 100 in the opposite direction, the piston 400 moves up. As a result, a negative pressure is generated inside the accommodation space of the transfer pipe 500, which makes it difficult to rotate the dial 100 in the reverse direction. This is because stronger resistance is generated during reverse rotation. Further, even if the dial 100 rotates in the reverse direction and the piston 400 rises by a predetermined length, the piston 400 can descend due to forward rotation again in the process of eliminating the negative pressure.

  The application part 800 contacts the user's skin and can apply the cosmetic material exhaled through the ejection path 712 to the skin. The coating part 800 may be formed in a ball type, as shown in FIG. Here, a housing space 716 having a shape corresponding to the coating unit 800 may be formed on the discharge head 710, the coating unit 800 is housed inside the housing space 716, and at least a part of the coating unit 800 is provided. Can be exposed to the outside. In addition, the ejection path 712 of the ejection head 710 may be formed to penetrate at least a part of the accommodation space 716 so that the cosmetic material ejected through the ejection path 712 is supplied to the application unit 800.

  Specifically, a part corresponding to a predetermined height from the center line of the coating part 800 can be housed inside the housing space 716. This makes it possible to prevent a part of the coating unit 800 from being exposed to the outside, but prevent the coating unit 800 from being separated to the outside of the accommodation space 716.

  In particular, the application unit 800 may be spaced apart from the inner surface of the accommodation space 716 at a predetermined interval, and thus the application unit 800 may rotate inside the accommodation space 716 so that the cosmetic may be smoothly applied to the skin. it can.

  Although a ball type coating unit 800 is shown in FIG. 9, various configurations of the coating unit can be applied depending on the embodiment to which the present invention is applied. For example, a brush type application unit can be applied. Also, depending on the embodiment, the application part may not be applied to the cosmetic container of the present invention.

  The cover part 900 is for sealing the ejection part 700 and the coating part 800, and can be detachably coupled to the ejection part 700, particularly the ejection head 710. A variety of configurations may be applied to the cover unit 900 and the ejection head 710 for such coupling. For example, screw parts corresponding to each other are formed on the inner surface of the lower end of the cover 900 and the outer surface of the lower end of the ejection head 710, and the cover 900 can be coupled to the ejection head 710 by screwing. Further, for example, an engagement groove may be formed in the inner surface of the lower end of the cover 900 in the circumferential direction, and the outer surface of the lower end of the ejection head 710 may be engaged with the engagement groove of the cover 900. By forming the protrusion, the cover 900 can be fitted to the ejection head 710.

  FIG. 10 illustrates the operation of a cosmetic container according to an embodiment of the invention.

  Referring to FIG. 10, after the user holds the lower end of the container part 200 with the cover part 900 of the cosmetic container 1000 accommodating the cosmetic in the container part 200 removed (i.e., the container part 200 does not rotate). If the dial 100 is rotated in the forward direction with a finger, the piston arm 300 and the piston 400 can be lowered into the container 200 by the rotation of the dial 100.

  Specifically, the lift guide part 520 of the transfer tube 500 separates the rotation of the piston arm 300 from the rotation of the dial 100, so that the rotation of the dial 100 can lower the piston arm 300 screwed with the dial 100 without rotation. it can. As a result, the piston 400 moves downward to press the cosmetic downward, the cosmetic is transferred upward along the transfer passage 510 of the transfer tube 500, and the discharge adjusting unit 720 is opened / closed by the rising discharge pressure of the cosmetic. When the member 722 opens the second communication hole 514, it can be discharged through the discharge unit 700.

At this time, the elastic piece 120 and the guide protrusion 130 of the dial 100 and the guide groove 230 of the container part 200 can control the rotating direction of the dial 100. That is, by allowing the dial 100 to rotate only in the forward direction, but preventing the dial 100 from rotating in the reverse direction, the piston 400 rises and is housed in the discharged cosmetic and / or transfer channel 510. It is possible to prevent the cosmetic material from flowing into the container part 200 again, or the air from flowing into the container part 200 and the transfer pipe 500, or the negative pressure from being generated.

A fastening ridge may be provided in the circumferential direction, and correspondingly, a fastening groove may be formed inwardly inside the container part 200 ′. By inserting the fastening ridge of the dial 100 ′ into the fastening groove of the container part 200 ′, it is possible to prevent the dial 100 ′ from coming off from the container part 200 ′. By forming the fastening groove in the circumferential direction, the dial 100 'can rotate relative to the container portion 200'.

  Further, the lower side of the connecting part 600 'is not connected to the upper end of the container part 200', but can be connected to the upper end of the dial 100 '. Specifically, the locking step 610 'of the connecting part 600' is hooked on the upper end surface of the dial 100 ', so that the connecting part 620' of the connecting part 600 'can be brought into close contact with the inside of the upper end of the dial 100'.
