Description

[Technical Field]

[0001] One aspect of the present disclosure relates to a cosmetic container, and more specifically, to a rotating discharge-type cosmetic container capable of conveniently and smoothly discharging a cosmetic content by a rotary operation.[Background Art]

[0002] In general, women use various cosmetics to make their appearance more beautiful, and color cosmetics among those cosmetics are used for the purpose of changing the appearance and making the skin beautiful to achieve more gorgeous looks.

[0003] The color cosmetics is used to make a skin color uniform and cover defects, and is divided into base makeup and point makeup which partially increases an three-dimensional effect on lips, eyes, nails, etc. The base makeup is composed of makeup base, foundation, powder, etc., and the point makeup includes lipstick, eyeliner, mascara, etc.

[0004] The foundation is a cosmetic product used to naturally cover blemishes, freckles or the like of the skin exposed to the outside, such as a face, or to express a clean and bright skin or a clear and elastic skin. When applying makeup using the foundation, the foundation is evenly spread and applied to the skin with a cosmetic puff without looking cakey.

[0005] The foundation is generally stored in a wide and flat cosmetic container, and a puff is embedded at an inner side of the cosmetic container. A user opens a lid of the cosmetic container, grasps the puff accommodated in an upper portion of an inner container lid, opens the inner container lid, and then coats the puff with the foundation cosmetic to apply the same to the skin.

[0006] However, since the conventional cosmetic container needs to be used in a state in which the lid of the container is opened, the cosmetic is completely exposed to the air, so that external foreign substances are easily introduced therein. Since a puff is repeatedly used while coming into contact with the cosmetic during use, the cosmetic is contaminated by bacteria, viruses, molds, etc., and thus there is a problem in that skin troubles are caused or a period of use is shortened. In addition, such conventional cosmetic container is used by taking out cosmetics with a cosmetic tool such as a puff or a finger, and thus there is a problem in that the amount of cosmetics used is not always constantly adjusted, thus resulting in waste of cosmetics and inconvenience of use.

[0007] Accordingly, a cosmetic container has been developed that minimizes deterioration and contamination during the use of cosmetics, is convenient to use, and is capable of constantly controlling a discharge amount of cosmetics.

[0008] As a related art having such a structure, cosmetic containers have been disclosed in Korean Registered Patent No. 10-2188196 (hereinafter, referred to as "related art 1") and Korean Registered Patent No. 10-2279516 (hereinafter, referred to as "related art 2"), which will be described as follows.

[0009] Said related art 1 includes an inner case having an inner space, a rotary bezel rotatably coupled to an upper portion of the inner case and having a discharge hole, a rotary member located in the inner space and coupled to the rotary bezel to rotate integrally with the rotary bezel, and a piston located in the inner space and coupled to the rotary member to move up and down in conjunction with the rotation of the rotary member. However, said related art 1 has a structure, in which the rotary member is screw-coupled to a center of the piston and an edge of the piston comes into close contact with an inner wall of the inner case, and when the piston does not completely come into close contact with the inner case, there is a problem in that the piston is rotated together with the rotary member at a time of a rotation operation of the rotary bevel and is not moved up and down with respect to the rotary member as an axis, thereby causing an operation failure.

[0010] Said related art 2 includes a body having an inner space, a dial rotatably coupled to an upper portion of the body and including a discharge hole through which content is discharged and a cutter for grinding the content, a screw positioned at a lower portion of the dial in the inner space and rotating integrally with the dial, and a piston screw-coupled to a circumference of the screw to move up and down an inside of the inner space by rotation of the screw. However, said related art 2 has a structure, in which a coupling protrusion of the dial is inserted into a center of the screw to rotate together, and as a gap between the coupling protrusion and the screw becomes loose, the screw idles with respect to the dial or the screw shakes from the dial, and thus there is a structural problem in that a discharge operation of a cosmetic content is not smoothly performed.

[0011] Thus, there is a need to develop a rotating discharge-type cosmetic container which is convenient to discharge and use the cosmetic content and in which a process of discharging the cosmetic content is performed stably and smoothly without an operational defect.[Related Art Reference][Patent Documents]

[0020] Besides, the rotary operation member may include a coupling portion screw-coupled to the elevation member, and a close contact portion extending outward from an end of the coupling portion to come into close contact with one surface of the rotary member.

[0021] Additionally, a cutting blade of the rotary operation member may be a linear protrusion extending long from a center of the rotary operation member to an edge portion thereof, and may be formed to protrude toward a cosmetic content accommodated in the inner container, and to be inclined in a rotational direction of the rotary operation member.

[0022] Likewise, the content passage hole of the rotary operation member may be formed at a position adjacent to the cutting blade, and may be connected to the discharge port of the rotary member.[Advantageous Effects]

These embodiments will be described in detail to be sufficient for those skilled in the art to practice one aspect of the present disclosure. It needs to be understood that various embodiments of one aspect of the present disclosure are different from each other, but need not be mutually exclusive. For example, specific shapes, structures, and properties described herein may be implemented as other embodiments without departing from the spirit and scope of one aspect of the present disclosure in relation to one embodiment. In addition, it needs to be understood that the position or arrangement of individual components within each described embodiment may be changed without departing from the spirit and scope of one aspect of the present disclosure.

[0028] Thus, the detailed description to be described below is not intended to be limiting, and the scope of one aspect of the present disclosure is limited only by the appended claims, as well as all the scope equivalent to those claimed by the claims, if properly described. In the drawings, similar reference numerals refer to the same or similar functions throughout the several aspects.

[0029] The terms used in one aspect of the present disclosure have been selected as currently widely used general terms as possible while considering the functions in one aspect of the present disclosure, but these may vary depending on the intention or precedent of a person skilled in the art, the emergence of new technologies, and the like. In addition, in specific cases, there are terms arbitrarily selected by the applicant, and in this case, the meaning thereof will be described in detail in the corresponding description of one aspect of the present disclosure. Thus, the terms used in one aspect of the present disclosure need to be defined based on the meaning of the terms and the contents throughout one aspect of the present disclosure, rather than the simple names of the terms.

[0030] In one aspect of the present disclosure, when a part is said to "include" a certain component, it means that the part may further include other components rather than excluding the other components, unless otherwise particularly specified. Hereinafter, a rotating discharge-type cosmetic container according to an embodiment of one aspect of the present disclosure will be described in detail with reference to the accompanying drawings.

[0031] FIG. 1 is a perspective view of a cosmetic container according to an embodiment of one aspect of the present disclosure, FIG. 2 is an exploded perspective view of a cosmetic container according to an embodiment of one aspect of the present disclosure when viewed from above, FIG. 3 is an exploded perspective view of a cosmetic container according to an embodiment of one aspect of the present disclosure when viewed from below, FIG. 4 is an exemplary perspective view showing a state in which an overcap of a cosmetic container according to an embodiment of one aspect of the present disclosure is separated, FIG. 5 is a sectional view taken along line A-A of FIG. 4, and FIG. 6 is a sectional view taken along line B-B of FIG. 4.

[0032] As shown in a drawing, the rotating discharge-type cosmetic container according to an embodiment of one aspect of the present disclosure may include an outer container 10, an inner container 20, a rotary member 30, a rotary operation member 40, and an elevation member 50.

[0033] The rotating discharge-type cosmetic container according to an embodiment of one aspect of the present disclosure will be described separately for each configuration as follows.

[0034] The outer container 10 may take on a hard cylindrical shape with one side thereof open and a space having a predetermined size therein, and at least a portion of the inner container 20 may be inserted and coupled to an inner space thereof. The outer container 10 is not limited to a hard cylindrical shape, and may be formed in various shapes or materials in consideration of a type of a cosmetic content stored therein, usability, design factors or the like.

[0035] As shown in FIGS. 2 and 3, a fixing body 60 may be further coupled to an inner side of the outer container 10. The fixing body 60 may easily and stably assemble and fix the inner container 20 to the inner side of the outer container 10, and may include a cylindrical first fixing body 62, both sides of which are open, and a ring-shaped second fixing body 64. The first fixing body 62 and the second fixing body 64 may be fixedly coupled to the inner side of the outer container 10 while being connected to each other, in which the first fixing body 62 may be completely inserted into an inner space of the outer container 10 to become an inner wall of the outer container 10, and the second fixing body 64 may be fixed to an end of the first fixing body 62 and at least a portion thereof may be exposed to one open side of the outer container 10.

[0036] The first fixing body 62 may be formed with a detachable protrusion 62a and a fitting groove 62b. The detachable protrusion 62a, which is a configuration for refilling the inner container 20, may be formed to protrude from an inner circumferential edge of the first fixing body 62 to be detachably coupled to the inner container 20, and the fitting groove 62b, which is a configuration for preventing a rotation of the fixing body 60 with respect to the outer container 10, may be formed on an outer wall of the first fixing body 62 to be fitted and coupled to a fitting protrusion 12 formed at the outer container 10. In this case, it may be preferable that the detachable protrusion 62a is formed to protrude in a pair and disposed to face each other for stable coupling between the inner container 20 and the fixing body 60, and the fitting groove 62b and the fitting protrusion 12 extend long in an insertion direction of the fixing body 60. In the rotating discharge-type cosmetic container according to an embodiment of one aspect of the present disclosure, the outer container 10 and the fixing body 60 may be separately formed and fixedly coupled to each other as an example, but one aspect of the present disclosure is not limited thereto, and the fixing body 60 may be integrally injection-molded on an inner wall of the outer container 10.

[0037] Meanwhile, one side of the outer container 10 may further include an overcap 70 for opening or closing the rotary member 30. The overcap 70 may be detachably fastened to the inner container 20 while covering the rotary member 30, may be separated from the inner container 20 when in use to expose the rotary member 30 to the outside, and may be coupled to the inner container 20 when stored or carried to protect the rotary member 30. Of course, the overcap 70 may be detachably fastened to the outer container 10 or the fixing body 60 rather than the inner container 20.

[0038] The inner container 20 may be detachably coupled to the inner side of the outer container 10, and a cosmetic content may be accommodated in the inner space thereof. In this case, it may be preferable that the cosmetic content is a solid cosmetic product which is linearly moved by an elevation member 50 and of which an upper surface is cut by the rotary member 30.

[0039] An inlet portion 22 may be formed at one side of the inner container 20, and the cosmetic content may be moved to the rotary member 30 and the rotary operation member 40 through the inlet portion 22.

[0040] An elevation guide protrusion 24 may be formed to protrude from an inner circumferential edge of the inner container 20. The elevation guide protrusion 24, which is a configuration coupled to the elevation member 50 to guide a linear movement while preventing a rotation of the elevation member 50, may be formed to extend in a movement direction of the elevation member 50 and may be formed in at least a pair to face each other.

[0041] In addition, an insertion protrusion 27 may be formed inside the inner container 20. The insertion protrusion 27 may be formed to protrude from a center of a bottom surface of the inner container 20 at a predetermined height, and may be inserted into an inner side of the rotary operation member 40 so that the rotary operation member 40 may rotate in place without shaking.

[0042] Meanwhile, a protrusion 25 may be formed to protrude outward from an outer circumferential edge of the inner container 20, a first coupling protrusion wheel 26, to which the rotary member 20 is rotatably coupled, may be formed at one side of the protrusion 25, and a detachable groove 28, which is detachably coupled to the fixing body 10, may be formed at the other side thereof. The detachable groove 28 may include an insertion section 28a extending in an insertion direction of the inner container 20 with respect to the outer container 10 and a holding section 28b connected to an end of the insertion section 28a, extending at a right angle, and having a holding protrusion 28c, and the inner container 20 may be detached from and attached to the fixing body 60 while the detachable protrusion 62a of the fixing body 60 is inserted into or removed from the insertion section 28a and the holding section 28b. In this case, it may be preferable that the first coupling protrusion wheel 26 is formed to extend along an outer circumference of the inner container 20, and the fastening groove 28 is formed in at least one pair to be symmetrical to each other.

[0043] In other words, when the inner container 20 is pushed into an inner space of the fixing body 60 while the detachable protrusion 62a is inserted into the insertion section 28a of the detachable groove 28 and the inner container 20 is continuously rotated in any one direction with respect to the fixing body 60, the detachable protrusion 62a may be inserted into the holding section 28b of the detachable groove 28, and thus the inner container 20 and the fixing body 60 may be fixedly coupled to each other. In addition, when the inner container 20 is rotated in an opposite direction with respect to the fixing body 60 to move the detachable protrusion 62a from the holding section 28b of the detachable groove 28 to the insertion section 28a and the inner container 20 is continuously pulled from the fixing body 60, the detachable protrusion 62a may be released from the insertion section 28a, and thus the inner container 20 and the fixing body 60 may be separated from each other.

[0044] The rotary member 30 may be rotatably coupled to the inner container 20 and rotatably operated by a user, so that the cosmetic content accommodated in the inner container 20 may be discharged to the outside.

[0045] As shown in FIG. 4, the rotary member 30 may be formed with a discharge surface 32 which is exposed to the outside to come into a direct contact with a cosmetic tool or a user's finger, and the discharge surface 32 may be formed with a discharge port 32a for discharging the cosmetic content accommodated in the inner container 20 to the outside. It may be preferable that the discharge surface 32 is formed to be recessed inward from an upper portion of the rotary member 30 so that the content discharged from the inner container 20 may not flow down to an outer side of the rotary member 30, and the discharge port 32a is a linear hole extending long from a center of the discharge surface 32 to an edge portion thereof. At this time, both side walls of the discharge port 32a may be formed to be inclined at a predetermined angle in a rotational direction of the rotary member 30 for smooth discharge of the cosmetic content. In the rotating discharge-type cosmetic container according to an embodiment of one aspect of the present disclosure, it has been described as an example that the discharge port 32a may have a linear shape extending long on the discharge surface 32, but one aspect of the present disclosure is not limited thereto, and the shape, number, or position of the discharge port 32a may be variously changed within a range in which the cosmetic content may be easily discharged to the outside.

[0046] As shown in FIG. 5, the rotary member 30 may be rotatably coupled to the inner container 20 while surrounding an open inlet portion 22 of the inner container 20 with the discharge surface 32, and one surface of the rotary operation member 40 may come into contact with an opposite surface of the discharge surface 32 as a whole.

[0047] Meanwhile, at least one discharge port 32a may be formed on the discharge surface 22, and when formed in plural, a plurality of discharge ports 32a may be radially disposed to be spaced apart from each other at a predetermined angle at an upper surface of the rotary member 30, and a discharge area or position of the cosmetic content may be variously adjusted according to the number of discharge ports 32a, an angle spaced apart from the adjacent discharge ports 32a, and the like. For example, the discharge port 32a may be intensively disposed at a portion of the discharge surface 32, so that the cosmetic content may be discharged while being limited to a partial area of the discharge surface 32. On the contrast, the discharge port 32a may be uniformly disposed over the discharge surface 32 as a whole, so that the cosmetic content may be discharged while widely spreading over an entire area of the discharge surface 32.

[0048] The rotary member 30 may be fixedly coupled to the rotary operation member 40 to transmit a rotational motion to the rotary operation member 40. As shown in FIG. 3, at least one rotation limiting protrusion 34 may be formed to protrude from an inner circumferential edge of the rotary member 30 to be fixedly coupled to the rotary operating member 40, and a second coupling protrusion wheel 36 may be formed to be rotatably coupled to a first coupling protrusion wheel 26 of the inner container 20. In the rotating discharge-type cosmetic container according to an embodiment of one aspect of the present disclosure, it has been described as an example that a protrusion may be formed at the inner container 20 and the rotary member 30, respectively, and undercut-coupled to each other, but one aspect of the present disclosure is not limited thereto, and the protrusion and the groove may be formed at the inner container 20 and the rotary member 30, respectively, so as to be fitted and coupled to each other.

[0049] Meanwhile, the inner container 20 and the rotary member 30 may further include a rotational direction control structure which allows the rotary member 30 to rotate in only one direction. In other words, the addition of the rotational direction control structure to each of the inner container 20 and the rotary member 30 may allow the rotary member 30 to be rotated only in an ascending direction of the elevation member 50, and may prevent the same from being rotated in a descending direction of the elevation member 50, thereby increasing the convenience of use. For example, a one-way rotary protrusion (not shown) which transmits rotation in only one direction, such as a ratchet gear - which transmits rotation in only one direction and does not transmit motion in an opposite direction - may be formed at an outer circumferential edge of the inner container 20 and an inner circumferential edge of the rotary member 30, respectively, to engage with each other.

[0050] The rotary operation member 40 may be formed inside the inner container 20 and may be rotated together with the rotary member 30 to discharge the cosmetic content to the discharge surface 32 of the rotary member 30.

[0051] As shown in FIGS. 2 and 3, the rotary operation member 40, which is a configuration for moving the elevation member 50 while being rotated by the rotary member 30 and for thinly cutting an upper surface of the cosmetic content moved by the elevation member 50, may include a hollow coupling portion 42 screw-coupled to the elevation member 50 and a close contact portion 44 extending outward from an end of the coupling portion 42 and coming into close contact with one surface of the rotary member 30. The coupling portion 42 may be rotated in place while being inserted into the insertion protrusion 27 of the inner container 20, and may be formed with a screw thread at an outer circumferential edge thereof so as to be screw-coupled to a screw thread formed on the elevation member 50, and the close contact portion 44 may be inserted and fixed to an inner space of the rotary member 40 to rotate together with the rotary member 40. Of course, the coupling portion 42 and the close contact portion 44 may be integrally injection-molded, or may be separately injection-molded, so that the coupling portion 42 may be fixedly coupled to a center of the close contact portion 44.

[0052] As shown in FIG. 6, the close contact portion 44 may be a portion which comes into close contact with an inner surface of the rotary member 30 as a whole for a stable rotary operation of the rotary operation member 40, and may be formed of a disk, through which at least a partial area is penetrated, and disposed between the inner container 20 and the rotary member 30. The close contact portion 44 may be formed with a cutting blade 44a for thinly cutting a surface of the cosmetic content and a content passage hole 44b, through which the cosmetic content cut by the cutting blade 44a passes. The cutting blade 44a, which is a linear protrusion extending long from a center of the rotary operation member 40 to an edge portion thereof, may be formed to protrude toward the cosmetic content accommodated in the inner container 20, may become sharper toward an end thereof, and may be formed to be inclined in a rotational direction of the rotary operation member 40. In addition, it may be preferable that the content passage hole 44b is formed at a position adjacent to the cutting blade 44a, is connected to the discharge port 32a of the rotary member 30, and extends from a center of the rotary operation member 40 to an edge portion thereof to have a fan shape with a predetermined area. Here, the cutting blade 44a may be located at a lower portion of the discharge port 32a and formed to extend in the same direction as the discharge port 32a, and the content passage hole 44b may be located in front of the cutting blade 44a in an inclined direction.

[0053] Meanwhile, one or more rotation limiting grooves 46 may be formed at an outer circumferential edge of the rotary operation member 40 to be coupled to the rotation limiting protrusion 34 of the rotary member 30. In this case, the at least one rotation limiting protrusion 34 and the at least one rotation limiting groove 46 may be formed in a relatively different shape or size so as to be distinguished from a remaining rotation limiting protrusion 34 and a remaining rotation limiting groove 46, so that the rotary member 30 and the rotary operation member 40 may be always assembled in a constant direction. In other words, as shown in a drawing, the rotation limiting protrusion 34 of the rotary member 30 and the rotation limiting groove 46 of the rotary operation member 40 may be formed as a protrusion or a groove, in which at least one rotation limiting protrusion 34 and at least one rotation limiting groove 46 may be formed as a double protrusion or a double groove so as to be coupled only to each other, so that the discharge port 32a of the rotary member 30 and the cutting blade 44a of the rotary operation member 40 may be always positioned up and down on the same line, and an assembly direction of the rotary member 30 and the rotary operation member 40 may be constantly controlled so that the content passage hole 44b may be connected to the discharge port 32a of the rotary member 30.

[0054] The elevation member 50 may be screw-coupled to the rotary operation member 40 to linearly move in an inner space of the inner container 20, and may push the cosmetic content to the inlet portion 22 of the inner container 20 in proportion to a rotation angle of the rotary operation member 40.

[0055] A through hole 52 may be formed at a center of the elevation member 50 to allow at least a portion of the rotary operation member 40 to pass therethrough, a screw thread may be formed at an inner circumferential edge of the through hole 52 to be screw-coupled to a screw thread formed at the rotary operation member 40, and the elevation member 50 may be linearly moved along an inner wall of the inner container 20 in a state in which an outer circumference thereof comes into close contact with the inner wall of the inner container 20.

[0056] As shown in FIGS. 2 and 3, an elevation guide groove 54 may be formed at an edge of the elevation member 50 to be coupled to an elevation guide protrusion 24 of the inner container 20. The elevation guide groove 54 may guide a linear movement of the elevation member 50 while preventing the elevation member 50 from rotating with respect to the inner container 20.

[0057] FIGS. 7 to 8 are views showing an operation process of the rotating discharge-type cosmetic container according to an embodiment of one aspect of the present disclosure, and a process of using the rotating discharge-type cosmetic container according to an embodiment of one aspect of the present disclosure will be described with reference thereto.

[0058] FIG. 7 is an exemplary sectional view showing a state in which a rotary member is rotated in FIG. 6, and FIG. 8 is an exemplary perspective view showing a state in which a cosmetic content is discharged to a discharge surface according to an embodiment of one aspect of the present disclosure.

[0059] In order to use the rotating discharge-type cosmetic container according to the embodiment of one aspect of the present disclosure, as shown in FIG. 4, an overcap 70 may be separated from the outer container 10 or the inner container 20 to expose the rotary member 30 to the outside.

[0060] After that, as shown in FIG. 7, when the rotary member 30 is rotated in any one direction with respect to the inner container 20, the rotary operation member 40 coupled to the rotary member 30 is rotated together, whereas a rotation of the elevation member 50 is restricted by the inner container 20. Accordingly, the elevation member 50 screw-coupled to the rotary operation member 40 may be gradually moved upward in proportion to a rotary section of the rotary operation member 40, and the cosmetic content may be pushed up in a direction of the rotary member 30 and the rotary operation member 40 by the elevation member 50.

[0061] At the same time, as the rotary member 30 and the rotary operation member 40 rotate, the cutting blade 44a may cut an upper surface of the cosmetic content, and the cosmetic content cut by the cutting blade 44a may be discharged to the discharge port 32a of the discharge surface 32 through the content passage hole 44b.

[0062] After that, the cosmetic content discharged to the discharge surface 32 of the rotary member 30 are taken by a cosmetic tool such as a puff (not shown) and applied evenly to the skin for makeup. After the makeup is finished, the rotary member 30 may be surrounded by the overcap 70 and may be coupled to the outer container 10 or the inner container 20 so as to be stored or carried.
