Description

Cosmetic container

Technical Field

The present invention relates to a cosmetic container, and more particularly, to a cosmetic container in which discharge of a cosmetic material can be more easily adjusted by rotation of a knob.

Background

In general, cosmetics are roughly classified into solid, powder, and liquid forms, and various containers are used depending on the form of the cosmetics. Recently, cosmetics such as foundation or lipstick are being supplied in a gel or liquid state which is not in a powder form or a solid form, and a hose container or a pump container has been used in large quantities in order to contain such liquid cosmetics.

When such a hose or pump type container is squeezed or a pump is pushed in order to discharge the cosmetic, it is not easy to adjust the amount of the cosmetic to be discharged as required, and it is not easy to use the whole amount of the cosmetic remaining in the container, which is inconvenient.

In order to solve such a problem, a rotary discharge type cosmetic container has been developed and used, which can pressurize and discharge the contained cosmetic material in accordance with the rising or falling of the piston by rotating the container by the user. However, the conventional rotary discharge type cosmetic has a problem that it is difficult to adjust the amount of the cosmetic to be discharged as required because it is not easy to estimate how much the piston moves when the user performs the rotary operation.

In addition, in the conventional rotary discharge type cosmetics, the rotary operation portion is generally located at the lower end of the container, and in order to discharge the cosmetic, the user needs to hold the container body portion with one hand and rotate the rotary operation portion with the other hand, so that there is inconvenience in using the cosmetics in a state where the small mirror is held with one hand.

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

Disclosure of Invention

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a cosmetic container capable of adjusting discharge of a cosmetic material more easily by rotation of a knob.

The technical problems of the present invention are not limited to the technical problems described above, and other technical problems not described above can be clearly understood by those skilled in the art from the following descriptions.

According to one embodiment of the present invention, a cosmetic container is provided. The container includes: a knob to which a rotational force is applied by a user; a container part which contains a cosmetic material on the lower side and is provided with the knob on the upper side in a relatively rotatable manner; a piston arm which is disposed inside the container portion and which is lifted and lowered by relative rotation of the knob with respect to the container portion; a piston which is disposed in close contact with an inner wall of the container portion, is coupled to a lower portion of the piston arm, and moves up and down together with the piston arm; and a transfer tube disposed inside the container portion and having a transfer flow path formed therein for transferring the cosmetic material along a longitudinal direction of the container portion; by the relative rotation of the knob, if the piston arm and the piston descend and pressurize the cosmetic, the cosmetic can flow into the lower portion of the transfer tube and be discharged through the transfer flow path.

Preferably, a non-circular (non-circular) cross-sectional elevation guide portion may be formed in one region of the transport pipe, and a through portion corresponding to the elevation guide portion may be formed inside the piston arm; and a lifting guide part inserted into the through part to prevent the piston arm from rotating and guide the piston arm to lift when the knob rotates relatively.

Preferably, the knob and the piston arm may be screwed together by forming threads corresponding to each other on an inner peripheral surface of the knob and an outer peripheral surface of the piston arm.

Preferably, at least one opening portion may be formed in an upper portion of the container portion to penetrate therethrough in a longitudinal direction, the knob may be disposed inside the upper portion of the container portion in which the opening portion is formed, and at least a portion of the knob may be exposed to the outside.

Preferably, the transfer pipe may further include a connecting portion having a hooking ridge protruding in a circumferential direction and placed on an upper end surface of the container portion and a coupling portion extending downward from a lower region of the hooking ridge and coupled to an inner side of the upper end of the container portion, and at least a part of the transfer pipe may be inserted and disposed inside the coupling portion.

Preferably, a first step may be formed on an outer circumferential surface of a lower portion of the knob in a circumferential direction, a second step corresponding to the first step may be formed on an inner circumferential surface of an upper portion of the container portion, and the first step may be placed on the second step, so that the knob may be disposed on an inner upper portion of the container portion.

In addition, preferably, an upper end of the knob may be supported by a lower surface of the coupling portion, and a lower end of the knob may be supported by the second step of the container portion, so that the lifting of the knob may be prevented.

Preferably, a guide groove is formed in an inner peripheral surface of the container portion, at least one elastic piece capable of being bent inward is formed in an outer peripheral surface of a lower end portion of the knob, and a guide projection corresponding to the guide groove is formed in one region of the elastic piece so as to protrude outward; the guide groove and the guide protrusion are formed in a form in which an inclined surface contacting in a rotation direction of the knob and elasticity are different, thereby guiding the forward rotation of the knob and preventing the reverse rotation.

Preferably, the guide groove may have a first inclined surface and a second inclined surface formed in opposite directions, the guide projection may have a third inclined surface and a fourth inclined surface formed in opposite directions, and the first inclined surface and the third inclined surface may have inclinations that are gentler than the second inclined surface and the fourth inclined surface, respectively.

In addition, it is preferable that if the forward rotation is applied to the knob, the elastic piece may be bent inward while the first inclined surface and the third inclined surface are in contact with each other, performing the forward rotation of the knob; if the reverse rotation is applied to the knob, the reverse rotation may be prevented while the second inclined surface is in contact with the fourth inclined surface.

Further, it is preferable that the discharge device further includes a discharge portion including: a discharge head which is coupled to the connection portion and the transfer pipe, respectively, and forms a discharge path through which the cosmetic material is discharged; and a discharge adjustment unit that opens and closes a communication hole through which the cosmetic material flows into the discharge head.

Further, it is preferable that the discharge adjustment unit includes: an elastic member supported by an inner lower surface of the discharge head and exerting an elastic force downward; and an opening/closing member which is pressed downward by the elastic member and seals the communication hole; the opening and closing member may open the communication hole by a discharge pressure of the cosmetic material according to the rotation of the knob.

In addition, it is preferable that the cosmetic applicator further includes an application section, at least a part of which is accommodated on an upper side of the discharge head, for applying the cosmetic discharged through the discharge passage to the skin.

According to the present invention, if the knob is rotated, the cosmetic in the container is pressurized and discharged while the piston is lowered, so that the discharge and discharge amount adjustment of the cosmetic can be finely and easily performed by the rotating operation, and the cosmetic in the container can be used without a surplus because the piston is lowered in close contact with the inner wall of the container.

Further, according to the present invention, the knob is disposed above the cosmetic container, so that it is not necessary to operate the cosmetic container with both hands, and the cosmetic is discharged by rotating the knob with the fingers in a state where the cosmetic container is held with one hand, thereby improving the convenience of operation.

Further, according to the present invention, the knob is configured to be rotatable only in one direction, which is advantageous in that the operation is easy, and the rotation load and the specific sound are generated, which is advantageous in that the user can easily grasp the degree of rotation (that is, the degree of lowering of the piston).

In addition, according to the present invention, since the structure required for the rotation and vertical movement of the piston has even a function of preventing the reverse rotation, and thus does not include another structure for controlling the rotation direction, economical effects can be obtained in manufacturing the container by simplifying the constituent parts.

Further, according to the present invention, since the discharge adjustment portion having the sealing member is provided, when the cosmetic container is stored, the leakage of the internal cosmetic can be prevented, and the rotation operation and the discharge amount adjustment of the cosmetic can be performed more easily.

In addition, according to the present invention, the application part is provided with the massage ball, so that the cosmetic can be applied to the skin by the massage ball.

Referring to fig. 1 to 8, the cosmetic container 1000 may include a knob 100, a container part 200, a piston arm 300, a piston 400, a transfer tube 500, a connection part 600, a discharge part 700, an application part 800, and a cap part 900.

The knob 100 is provided above the container portion 200, and can receive a rotational force applied by a user to rotate relative to the container portion 200. Specifically, the first step 110 is formed in the circumferential direction on the outer circumferential surface of the lower portion of the knob 100, and the second step 220 is formed on the inner circumferential surface of the upper portion of the container portion 200, so that the first step 110 of the knob 100 can be placed on the second step 220 of the container portion 200. Thereby, the knob 100 can be disposed inside the upper portion of the container portion 200.

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

In particular, the knob 100 is not coupled to the container portion 200 outside the container portion 200, but is rotated in a state of being disposed inside the container portion 200, and in this regard, it is possible to enable stable relative rotation of the knob 100.

On the other hand, a first screw thread may be formed on at least a portion of the inner peripheral surface of the lower end portion of the knob 100, and a second screw thread corresponding to the first screw thread may be formed on at least a portion of the outer peripheral surface of the piston arm 300 inserted inside the lower end portion of the knob 100. Thus, the knob 100 is screwed to the piston arm 300, and the piston arm 300 can be moved up and down according to the rotation of the knob 100. This is explained in more detail below.

The container portion 200 may contain cosmetics therein. The cosmetic material is a material that can be applied to and/or absorbed by the skin of the user for the purpose of beauty or the like, and preferably, a liquid cosmetic material, but is not limited thereto.

The container portion 200 functions with reference to the rotation of the knob 100, and may be provided so that the knob 100 can relatively rotate upward. Specifically, the knob 100 is disposed rotatably relative to the inside of the upper portion of the container portion 200, and at least a part of the knob 100 is exposed to the outside through the opening portion 210, so that the rotational force of the user can be transmitted to the knob 100 disposed inside the container portion 200. In this case, the open portion 210 may be formed by penetrating at least a part of the upper portion of the container portion 200 in the longitudinal direction of the container portion 200, and may be formed of at least one member.

On the other hand, the knob 100 is disposed to be rotatable with respect to the container portion 200, and the rotation direction of the knob 100 can be guided by interlocking the knob 100 and the container portion 200 with each other. Specifically, the knob 100 can be rotated only in the forward direction, and thus the piston arm 300 and the piston 400 can be lowered. That is, the reverse rotation of the knob 100 is prevented, and the piston arm 300 and the piston 400 are prevented from being lifted.

For this, at least one guide groove 230 may be continuously formed in the circumferential direction on the inner circumferential surface of the container part 200. The guide groove 230 may be continuously formed from the second step 220 in the length direction of the container part 200, and may have a first inclined surface 232 and a second inclined surface 234, respectively. Correspondingly, at least one elastic piece 120 capable of bending in the inward direction may be formed on the outer peripheral surface of the lower end portion of the knob 100. In one region of each elastic piece 120, a guide protrusion 130 may be formed to protrude in a length direction corresponding to the guide groove 230, and each guide protrusion 130 may have a third inclined surface 132 and a fourth inclined surface 134.

In the guide groove 230, the first inclined surface 232 and the second inclined surface 234 may be formed in opposite directions to each other, and have different inclinations from each other. For example, the first inclined surface 232 may have a gentler inclination than the second inclined surface 234. Similarly, the third inclined surface 132 and the fourth inclined surface 134 may be formed in opposite directions to each other, and have different inclinations from each other. 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 perpendicular to the inner circumferential surface of the container portion 200 and the outer circumferential surface of the knob 100, respectively. In contrast to the gentle inclination, the steep inclination may be defined if the inclination of the inclined surface is close to the normal of the circumference.

On the other hand, the elastic piece 120 of the knob 100 may be formed to be bendable inward of the knob 100 by cutting at least a partial region of the lower end portion of the knob 100. In fig. 4, the upper end of the elastic piece 120 is integrally formed with the knob 100, and the left, right and lower ends of the elastic piece 120 are cut and penetrated so that the elastic piece 120 is formed in the longitudinal direction of the knob 100, but 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 formed integrally with the knob 100, and the upper end, the lower end and the left side are cut and penetrated, or differently from this, the left side of the elastic piece 120 is formed integrally with the knob 100, and the upper end, the lower end and the right side are cut and penetrated, so that the elastic piece 120 may be formed along the circumferential direction of the knob 100.

If the knob 100 is disposed inside the upper portion of the container part 200, the guide protrusions 130 of the knob 100 may be inserted into the guide grooves 230 of the container part 200. In this state, when the knob 100 is rotated 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 portion 200 having a gentle inclination, and a part of the forward rotational force can be converted into a force that presses the elastic piece 120 inward by the first inclined surface 232 and the third inclined surface 132. Accordingly, the elastic piece 120 is bent toward the inside of the knob 100, so that the third inclined surface 132 of the elastic piece 120 goes over the first inclined surface 232 of the container part 200, and thus the forward rotation can be performed.

In contrast, when the knob 100 is rotated reversely, the fourth inclined surface 134 of the elastic piece 120 may be in contact with the second inclined surface 234 of the container portion 200. Since the second inclined surface 234 and the fourth inclined surface 134 have relatively steep inclinations, the reverse rotational force is not converted into a force for pressing the elastic piece 120 inward by the second inclined surface 234 and the fourth inclined surface 134, and therefore the fourth inclined surface 134 of the elastic piece 120 cannot go over the second inclined surface 234 of the container portion 200, and as a result, the reverse rotation is not performed.

In particular, when the knob 100 is rotated in the forward direction, a user applies force for elastic deformation of the elastic piece 120 and thus feels a rotational load, and in the process of restoring after the elastic piece 120 is elastically deformed, 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 generate a "click" sound, thereby allowing the user to recognize and adjust the rotational operation through the rotational load and the sound.

On the other hand, the guide groove 230 of the container part 200 is formed in at least one shape and includes at least one inner recessed region not directly contacting the knob 100 (particularly, the lower region of the first step 110 of the knob 100), so that friction that may occur when the knob 100 is rotated can be reduced or removed, and the rotation of the knob 100 can be smoothly performed.

According to an embodiment, at least a portion of the container portion 200 may be formed of a transparent or translucent material. Thereby, the user may operate the knob 100 while confirming the movement of the piston 400 or the remaining amount of the cosmetic inside the container part 200.

At least a portion of the piston arm 300 may be disposed inside the knob 100 and be lifted and lowered by rotation of the knob 100. Specifically, a second screw corresponding to a first screw formed on an inner peripheral surface of a lower end portion of the knob 100 is formed on at least a portion of an outer peripheral surface of the piston arm 300, so that the knob 100 and the piston arm 300 can be screwed together. At this time, when the knob 100 is rotated, the piston arm 300 is not rotated together but is rotated and fixed, and thus the piston arm 300 can be lifted and lowered by the rotation of the knob 100. As will be described in greater detail below, the take-off tube 500 may be inserted inside the plunger arm 300 in order to prevent synchronous rotation of the plunger arm 300 relative to the knob 100.

The piston 400 is disposed inside the container portion 200, and has an outer peripheral surface closely contacting the inner surface of the container portion 200 and an inner peripheral surface closely contacting the outer surface of the transport pipe 500. The piston 400 may be coupled to a lower portion of the piston arm 300 to be lifted and lowered together with the piston arm 300. That is, if the piston arm 300 descends by the rotation of the knob 100, the piston 400 descends together, and the cosmetic contained in the lower side can be pressurized. The pressurized cosmetic may be moved and discharged to the outside through the transfer tube 500. The piston 400 may be made of a material having elasticity such as rubber or silicone rubber in order to enhance the adhesion force with the inner surface of the container portion 200 and the outer surface of the transport pipe 500. However, this is merely exemplary, and may be formed of various materials according to an embodiment to which the present invention is applied.

The transfer tube 500 is disposed inside the container unit 200 to transfer the cosmetic material contained in the lower side of the container unit 200 to the upper side, and may include a transfer flow path 510 formed inside the transfer tube 500 to allow the cosmetic material to move, a lifting guide 520 formed in at least one region of the outer surface of the transfer tube 500, and a support 530 formed at the upper end of the transfer tube 500.

The transfer flow path 510 may be formed along the longitudinal direction of the container unit 200 inside the transfer tube 500, and defines a transfer path of the cosmetic. The transfer flow path 510 may include a first communication hole 512 at a lower side through which the cosmetic contained in the container unit 200 flows, and a second communication hole 514 at an upper side through which the cosmetic is discharged. The first communication hole of the transfer flow path 510 may be formed at or near the lower surface of the container unit 200 so as not to leave the remaining amount of the discharged cosmetic material. Further, as shown in the figure, the lower end of the transfer tube 500 is opened in the lateral direction, and the cosmetic can be flowed into the first communication hole 512 in the lateral direction.

The elevation guide part 520 may prevent the relative rotation of the piston arm 300 and guide the elevation of the piston arm 300. That is, even if the knob 100 is rotated, the piston arm 300 may be not rotated, so that the piston arm 300 is lifted and lowered.

Specifically, the elevation guide part 520 may be formed in one region in the longitudinal direction in the outer surface of the transport pipe 500, and the outer surface may have a non-circular (non-circular) cross section. Correspondingly, a through portion 310 into which the elevation guide portion 520 is inserted is formed inside the piston arm 300, and the through portion 310 may be formed in a non-circular shape like the elevation guide portion 520.

As described above, the piston arm 300 and the transport pipe 500 can be prevented from rotating relative to each other (that is, the piston arm 300 can be rotated in synchronization with the transport pipe 500) by the through portion 310 and the elevation guide portion 520 formed in a non-circular shape, and therefore, the piston arm 300 can be rotated and separated from the knob 100 with respect to the rotation. Further, since the knob 100 is screwed to the piston arm 300 inserted inside and prevented from being lifted up by the connection part 600 and the container part 200, the knob 100 can be lifted up and down not with reference to the piston arm 300 but with the piston arm 300 lifted up and down along the lifting and lowering guide part 520 by the rotation of the knob 100.

That is, when the user grips the container part 200 and rotates the knob 100, the knob 100 is rotated in a state in which the up-and-down movement is fixed, and the piston arm 300 screwed with the knob 100 is rotated and separated from the rotation of the knob 100 by the elevation guide part 520 of the transport pipe 500, whereby the rotational movement of the knob 100 can be converted into the vertical movement of the piston arm 300 and elevated.

On the other hand, the penetrating portion 310 of the piston arm 300 may be formed in a non-circular shape like the elevation guide portion 520, and may include a region 312 in contact with the elevation guide portion 520 and a region 314 spaced apart from the elevation guide portion 520. This is to reduce the contact surface with the transport pipe 500 disposed in the through portion 310, and to allow the piston arm 300 to move up and down more smoothly.

The support part 530 is formed at the upper end of the transport pipe 500 (particularly, at the upper side of the second communication hole 514), the upper side is coupled to the discharge part 700, and the lower side is supported by the connection part 600, so that the transport pipe 500 can be stably disposed in the cosmetic container 1000.

Specifically, the supporting part 530 may include: a catching rib 532 formed to be protruded in a circumferential direction so that the transport pipe 500 is placed on the upper end of the connection part 600; an accommodating portion 534 formed recessed inside the hooking rib 532 so as to communicate with the transfer flow path 510, and accommodating the discharge adjustment portion 720; and a coupling portion 536 extending upward from the hanging rib 532 and coupled to the inside of the ejection head 710.

The receiving portion 534 may be formed with a space that communicates with the second communication hole 514, into which the cosmetic material can flow, and the discharge adjustment portion 720 may be sufficiently arranged and operated. Further, the transport pipe 500 is disposed inside the connection portion 600, and the housing portion 534 may have an outer diameter corresponding to the through hole of the connection portion 600 so that the transport pipe 500 does not shake or come off. The coupling portion 536 is formed to protrude upward, and is closely attached to the inner surface of the discharge head 710 of the discharge portion 700, and a hooking groove is formed in the circumferential direction, so that a hooking protrusion formed on the inner surface of the discharge head 710 can be inserted and engaged.

The connecting portion 600 is coupled to the upper end of the container portion 200 at the lower side and coupled to the discharge portion 700 at the upper side, so that the transport pipe 500 can be inserted and disposed inside.

Specifically, a hooking ridge 610 protruding in the circumferential direction is formed on the outer circumferential surface of the connection portion 600, and the hooking ridge 610 can be placed on the upper end of the container portion 200. In addition, a coupling portion 620 extended downward is formed at a lower region of the hooking ridge 610, and if the hooking ridge 610 is seated on the upper end surface of the container portion 200, the coupling portion 620 may be closely attached to the inside of the upper end of the container portion 200. At this time, at least one hooking protrusion is formed on the outer circumferential surface of the coupling portion 620, a corresponding hooking groove is formed on the inner circumferential surface of the upper end of the container portion 200, and the hooking protrusion is inserted into the hooking groove, so that the coupling portion 600 can be coupled to the container portion 200.

As described above, if the connection part 600 is coupled to the upper end of the container part 200, the lower surface of the coupling part 620 may contact or approach the upper end surface of the knob 100. That is, such that the upper side of the knob 100 is supported by the connection part 600, as previously described, such that the lower side of the knob 100 is supported by the container part 200, it is possible to make the knob 100 stably rotate relatively with respect to the container part 200 without moving up and down.

A through hole may be formed inside the connection portion 600 to penetrate vertically. The transfer pipe 500 can be inserted and disposed inside the through hole, and particularly, at least a part of the transfer pipe 500 (i.e., the outside of the housing part 534) corresponds to the inner diameter of the through hole, so that the transfer pipe 500 can be stably placed on the connection part 600. Further, a hooking groove may be formed in a circumferential direction on an upper side of the connection portion 600, so that the discharge head 710 may be coupled to the connection portion 600.

Although the connection part 600 is illustrated as a separate structure from the transport pipe 500, this is only exemplary, and the connection part 600 and the transport pipe 500 may be implemented in one structure according to an embodiment to which the present invention is applied.

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

The discharge head 710 may communicate with the transfer tube 500 to discharge the cosmetic, and may have an inner lower end coupled to the upper end of the connection portion 600 and an inner upper end coupled to the transfer tube 500. To this end, the discharge head 710 may be formed with a discharge passage 712, and the discharge passage 712 communicates with the second communication hole 514 to provide a path for the movement of the cosmetic material.

Further, two hooking protrusions may be formed on the inner surface of the ejection head 710 so as to protrude in the circumferential direction. Wherein, the hooking protrusion at the upper side may be coupled to the hooking groove of the coupling portion 536 of the supporting portion 530. The hooking protrusion located at the lower side may be coupled to a hooking groove disposed at the upper side of the connection part 600.

A mounting portion 714 may be formed on the inner lower surface of the ejection head 710. The seating portion 714 is formed by a region recessed outside the discharge passage 712, and functions as a reference point for seating an elastic member 724 of the discharge adjusting portion 720, and supports the elastic member 724 such that the elastic member 724 generates an elastic force, as described in more detail below.

An accommodation space 716 is formed at the upper end of the discharge head 710 so as to be recessed inward, and the application unit 800 can be accommodated and arranged. However, this is merely exemplary, and the application part 800 and the receiving space 716 may not be used in the present invention according to an embodiment.

The discharge adjustment unit 720 is disposed inside the discharge head 710, and can adjust the discharge of the cosmetic material while opening and closing the second communication hole 514 of the transfer flow path 510. Specifically, the discharge adjustment portion 720 opens the second communication hole 514 when the knob 100 is rotated, and the cosmetic can be discharged to the outside through the discharge passage 712. In addition, when the knob 100 is not rotated, that is, in a normal storage state, the second communication hole 514 may be sealed so that the cosmetics do not leak.

For this, the discharge adjustment portion 720 may include an opening and closing member 722 having a larger inner diameter than the second communication hole 514 and formed in a ball shape, and an elastic member 724 pressing the opening and closing member 722.

The elastic member 724 is coupled to the mounting portion 714 outside the discharge passage 712, and can exert an elastic force downward. Therefore, the opening and closing member 722 pressed downward by the elastic member 724 can seal the second communication hole 514.

When the knob 100 is rotated and the cosmetic is moved up along the transfer flow path 510 by the downward movement of the piston 400, the opening/closing member 722 is moved up by the discharge pressure of the cosmetic, so that the second communication hole 514 is opened and the cosmetic can be moved to the discharge path 712, and when the rotation of the knob 100 is stopped, the opening/closing member 722 is again pressed by the elastic member 724 and the second communication hole 514 can be closed. Thereby, the cosmetic can be prevented from leaking without applying a rotational force to the knob 100.

On the other hand, the opening/closing member 722 is disposed above the second communication hole 514, and when the user attempts to rotate the knob 100 in the reverse direction while the second communication hole 514 is sealed, a negative pressure is generated in the housing space of the transfer tube 500 as the piston 400 rises, so that the knob 100 is prevented from rotating in the reverse direction. This is because stronger resistance occurs in reverse rotation. In addition, even if the knob 100 is rotated in the reverse direction and the piston 400 is raised by a predetermined length, the piston 400 may be lowered while being rotated in the forward direction again in the process of canceling the negative pressure.

The applicator 800 may contact the skin of the user and apply the cosmetic discharged through the discharge passage 712 to the skin. As shown in fig. 9, the coating portion 800 may be formed in a ball (bal) type. At this time, a housing space 716 having a shape corresponding to the coating portion 800 may be formed at an upper portion of the discharge head 710, the coating portion 800 may be housed inside the housing space 716, and at least a part of the coating portion 800 may be exposed to the outside. The discharge path 712 of the discharge head 710 is formed to penetrate at least a part of the accommodation space 716, and the cosmetic material discharged through the discharge path 712 can be applied to the application unit 800.

Specifically, the coating portion 800 can be accommodated inside the accommodating space 716 from the center line thereof to a portion corresponding to a predetermined height, so that a part of the coating portion 800 is exposed to the outside and does not come off the outside of the accommodating space 716.

In particular, the application unit 800 may be spaced apart from the inner side surface of the accommodating space 716 by a predetermined interval, so that the application unit 800 may rotate inside the accommodating space 716, thereby enabling the cosmetic to be smoothly applied to the skin.

In fig. 9, a ball-type coating portion 800 is illustrated, but various configurations of coating portions may be used according to an embodiment to which the present invention is applied. For example, a brush type coating portion may be used. In addition, according to the embodiment, the cosmetic container of the present invention may not use the application section.

The cap 900 is used to seal the discharge unit 700 and the application unit 800, and may be detachably coupled to the discharge unit 700, particularly, to the discharge head 710. For such coupling, various configurations can be applied to the cap 900 and the ejection head 710. For example, the inner surface of the lower end of the cap 900 and the outer surface of the lower end of the discharge head 710 are provided with corresponding screws, and the cap 900 can be coupled to the discharge head 710 by screwing. For example, a hooking groove may be formed in the circumferential direction on the inner surface of the lower end of the cap 900, and a hooking protrusion may be formed on the outer surface of the lower end of the discharge head 710 so as to correspond to the hooking groove of the cap 900, so that the cap 900 may be inserted into and coupled to the discharge head 710.

Referring to fig. 10, in a state where the cap portion 900 of the cosmetic container 1000 containing the cosmetic in the container portion 200 is removed, if the user rotates the knob 100 in the forward direction with the fingers after gripping the lower end of the container portion 200 (i.e., while not rotating the container portion 200), the piston arm 300 and the piston 400 can be lowered in the container portion 200 by the rotation of the knob 100.

Specifically, the piston arm 300 is separated from the rotation of the knob 100 by the elevation guide part 520 of the delivery pipe 500, and therefore, the piston arm 300 screwed with the knob 100 can be lowered without rotating by the rotation of the knob 100. Thereby, the piston 400 is lowered to pressurize the cosmetic material downward, the cosmetic material is transferred upward along the transfer flow path 510 of the transfer tube 500, and the opening and closing member 722 of the discharge adjustment portion 720 opens the second communication hole 514 by the raised discharge pressure of the cosmetic material, thereby enabling discharge through the discharge portion 700.

At this time, the elastic pieces 120 and the guide protrusions 130 of the knob 100 and the guide grooves 230 of the container part 200 may control the rotation direction of the knob 100. That is, the knob 100 is rotated only in the forward direction to prevent the reverse rotation, and the piston 400 is raised, and the discharged cosmetic and/or the cosmetic contained in the transfer passage 510 are prevented from flowing into the container unit 200 again, or air is allowed to flow into the container unit 200 and the transfer pipe 500, or negative pressure is generated.

In which fig. 11 (a) illustrates a front view of the cosmetic container, and fig. 11 (b) illustrates a sectional view of the cosmetic container.

The cosmetic container 1000' of fig. 11 is the same as the cosmetic container 1000 of fig. 1 to 10, and redundant description thereof will be omitted.

Referring to fig. 11, since the knob 100 ' is provided on the upper side of the container portion 200 ' and no open portion is formed in the container portion 200 ', the knob 100 ' is relatively rotatably disposed on the upper end portion of the container portion 200 '.

Specifically, the knob 100 ' is at least partially inserted into the container portion 200 ', and the first step 110 ' formed on the outer circumferential surface is seated on the upper end surface of the container portion 200 ', so as to be disposed at the upper end of the container portion 200 '. At this time, although not shown in fig. 11, a coupling protrusion may be formed to protrude in a circumferential direction on an outer circumferential surface of the knob 100 '(particularly, on a lower side of the first step) in order to rotatably couple the knob 100' and the container portion 200 ', and a coupling groove may be formed to be recessed inside the container portion 200'. The coupling protrusion of the knob 100 'is inserted into the coupling groove of the container part 200', so that the knob 100 'can be prevented from being separated from the container part 200', and such coupling protrusion and coupling groove can be formed in a circumferential direction so that the knob 100 'can be relatively rotated with respect to the container part 200'.

In addition, the connection part 600 ' may be coupled to the upper end of the knob 100 ', instead of being coupled to the upper end of the container part 200 ' at the lower side. Specifically, the hooking rib 610 'of the connection part 600' may be seated on the upper end surface of the knob 100 ', and the coupling part 620' of the connection part 600 'may be closely attached to the inside of the upper end of the knob 100'. At this time, at least one hooking protrusion is formed on the outer circumferential surface of the coupling portion 620 ', a corresponding hooking groove is formed on the inner circumferential surface of the upper end of the knob 100', and the hooking protrusion is inserted into the hooking groove, so that the coupling portion 600 'can be coupled to the knob 100'.

As described above, the preferred embodiments are disclosed in the drawings and the specification. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation or limitation, the scope of the invention being set forth in the claims. Therefore, as will be understood by those skilled in the art, various modifications and equivalent embodiments can be derived therefrom.
