Description

[Technical Field]

[0001] The present invention relates to a cosmetic container, and more particularly to a rotating discharge type cosmetic container that can be conveniently used by rotating the container to discharge the cosmetic contents. [Background technology]

[0002] Generally, women use various cosmetics to make their appearance more beautiful, and among these cosmetics, color cosmetics are used to beautify the appearance and make the skin look beautiful.

[0003] The color cosmetics are used to even out skin tone and cover imperfections, and are divided into base makeup and point makeup, which enhances the three-dimensional look of specific areas such as lips, eyes, and nails. Base makeup includes makeup base, foundation, and powder, while point makeup includes lipstick, eyeliner, and mascara.

[0004] The foundation is a cosmetic product used to naturally hide freckles and blemishes on exposed skin such as the face, or to create a clean, bright, or clear, smooth skin. When applying makeup using the foundation, the foundation is spread evenly and evenly on the skin using a cosmetic puff.

[0005] Such foundations are generally stored in wide, flat cosmetic containers with a built-in puff inside. A user opens the lid of the cosmetic container, grabs the puff stored above the lid, opens the lid, and then applies the foundation to the skin with the puff.

[0006] However, the conventional cosmetic containers have problems such as the cosmetics being completely exposed to the air and foreign substances easily entering the container because the lid must be left open when used, and the cosmetics are repeatedly brought into contact with the skin during use by the puff, which has come into contact with the cosmetics, thereby contaminating the cosmetics with bacteria, viruses, fungi, etc., which can cause skin troubles and shorten the usable period. Furthermore, the conventional cosmetic containers require the cosmetics to be dispensed little by little with a cosmetic tool such as a puff or with the fingers, which makes it difficult to constantly control the amount of cosmetics used, resulting in wastage of cosmetics and inconvenience in use.

[0007] As a result, cosmetic containers have been developed that minimize deterioration and contamination during the use of cosmetics, are convenient to use, and can regulate the amount of cosmetic dispensed at a constant rate.

[0008] Prior art having such a structure is disclosed in Korean Patent Registration No. 10-2188196 (hereinafter referred to as "Prior Art 1") and Korean Patent Registration No. 10-2279516 (hereinafter referred to as "Prior Art 2"), and the details of these are as follows.

[0009] Prior Art 1 includes an inner case with an inner space, a rotating bezel rotatably connected to the top of the inner case and having a discharge hole, a rotating member located in the inner space and connected to the rotating bezel to rotate integrally with the rotating bezel, and a piston located in the inner space and connected to the rotating member to rise or fall in conjunction with the rotation of the rotating member.

[0010] Prior Art 2 includes a body with an internal space, a dial rotatably connected to the top of the body and including a discharge hole through which the contents are discharged and a cutter for crushing the contents, a screw (threaded rod) located below the dial in the internal space and rotating integrally with the dial, and a piston threadedly connected to the screw and moving up and down within the internal space as the screw rotates.

[0011] However, since the prior arts 1 and 2 do not have a separate inner case refill structure, the entire cosmetic container must be discarded after using up all the contents stored in the inner case, which not only wastes resources but also pollutes the environment due to the discarded containers.

[0012] Therefore, there is a need to develop a stick-type cosmetic container that allows some parts of the cosmetic container to be replaced, thereby reducing the economic burden on users, reducing resource waste and environmental pollution, and allowing for convenient replacement of such parts.

[0013] [Patent Document 1] Korean Patent No. 10-2188196 (Announced on December 9, 2020) [Patent Document 2] Korean Patent No. 10-2279516 (Announced on July 21, 2021) Summary of the Invention [Problem to be solved by the invention]

[0014] In order to solve the above problems, the present invention aims to provide a rotary dispenser type cosmetic container in which an inner case is detachably connected to the inside of an outer case, and a rotating member is engaged with the inside of the outer case along the direction of attachment and detachment of the inner case, so that the rotating member, the inner case, and components connected thereto can be easily separated and replaced from the outer case. [Means for solving the problem]

[0015] In order to achieve the above-mentioned object, the present invention provides a rotary-dispensing cosmetic container including: an outer case having a first fixed connection part; a rotary actuating member rotatably connected to the inside of the outer case and having a first rotary connection part; an inner case detachably connected to the rotary actuating member and containing cosmetic contents therein; a rotary member rotatably connected to the inner case, having a second rotary connection part formed therein and having a discharge port on one side; an actuating member connected to the rotary actuating member and rotating relative to the rotary actuating member; an elevating member screw-connected to the actuating member, moving linearly within the inner case and having a second fixed connection part formed therein; and a piston that moves up and down together with the elevating member to move the cosmetic contents.

[0016] An overcap for opening and closing the rotary member is detachably connected to the outer case.

[0017] In addition, the first fixed connection part of the outer case and the second fixed connection part of the lifting member are formed to extend along the attachment / detachment direction of the inner case and are meshed with each other to restrict the rotation of the lifting member relative to the outer case.

[0018] The first and second fixed connecting portions are alternately formed to protrude from the surfaces of the outer case and the lifting member, respectively, which face each other.

[0019] The rotation actuating member and the inner case are respectively formed with a first detachable portion and a second detachable portion, and the first detachable portion and the second detachable portion are detachably connected to each other.

[0020] In addition, the first rotational connection part of the rotational actuating member and the second rotational connection part of the rotational member are formed to extend along the attachment / detachment direction of the inner case and are meshed with each other to transmit the rotational movement of the rotational member to the rotational actuating member.

[0021] The first and second rotary connecting portions are alternately formed on the opposing ends of the rotary actuating member and the rotary member, respectively, extending over a predetermined distance in the circumferential and axial directions.

[0022] The first and second rotary connection portions are formed at their ends with a first guide inclined surface and a second guide inclined surface, respectively.

[0023] The rotating member is characterized by having a cutting blade formed thereon for scraping off the surface of the cosmetic contents.

[0024] Furthermore, during the refilling process of fastening the inner case and the rotary actuating member, the first rotary connecting portion of the rotary actuating member and the second rotary connecting portion of the rotary member are meshed and fitted together, and at the same time, the first fixed connecting portion of the outer case and the second fixed connecting portion of the lifting member are meshed and fitted together. [Effects of the Invention]

[0025] According to the embodiment of the present invention, not only is the cosmetic content ejected to the outside by rotating the rotating member, but the amount of cosmetic content ejected can be easily adjusted depending on the rotation angle of the rotating member, which has the effect of improving convenience in use.

[0026] According to an embodiment of the present invention, the rotating member, the inner case, and the components connected thereto can be conveniently separated and replaced in one go by simply pulling out the rotating member and inserting the inner case relative to the outer case.

[0027] According to the embodiment of the present invention, the inner case, which has been completely depleted of cosmetic contents, can be refilled (replaced with the entire refill container) from the outer case and used again. This refill structure not only reduces the economic burden on the user, but also has the effect of reducing waste of resources. [Brief explanation of the drawings]

It should also be understood that the location or arrangement of individual components within each described embodiment may be changed without departing from the spirit and scope of the present invention.

[0030] Accordingly, the following detailed description is not to be taken in a limiting sense, and the scope of the present invention is limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled when properly interpreted. Like reference numerals in the drawings refer to the same or similar features throughout the various aspects.

[0031] The terms used in this invention are currently commonly used and have been selected as much as possible while taking into consideration the functions of the present invention, but these may change depending on the intentions of engineers in the field, precedents, the emergence of new technologies, etc. In addition, in certain cases, the applicant may arbitrarily select terms, and in such cases, their meanings will be described in detail in the relevant description of the invention. Therefore, the terms used in this invention should be defined based on the meanings of the terms and the overall content of the present invention, rather than simply by their names.

[0032] In the present invention, when a part "comprises" a certain element, this does not mean that other elements are excluded, but that other elements may be further included, unless otherwise specified. Hereinafter, a rotary dispenser type cosmetic container according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0033] FIG. 1 is a perspective view of a cosmetic container according to one embodiment of the present invention, FIG. 2 is an exploded perspective view of a cosmetic container according to one embodiment of the present invention viewed from above, FIG. 3 is an exploded perspective view of a cosmetic container according to one embodiment of the present invention viewed from below, and FIG. 4 is a cross-sectional view of a cosmetic container according to one embodiment of the present invention.

[0034] As shown in the figure, the rotary dispensing cosmetic container according to an embodiment of the present invention may be configured to include an outer case (10), a rotary actuating member (20), an inner case (30), a rotating member (40), an actuating member (50), a lifting member (60), and a piston (70).

[0035] The rotary dispenser type cosmetic container according to the embodiment of the present invention will be described below with respect to each of its components.

[0036] The outer case (10) is in the form of a hard cylinder with one side (the upper side in the drawing) open and a certain size of space inside, into which the rotary actuation member (20) and at least a part of the inner case (30) are inserted and coupled. The outer case (10) is not limited to a hard cylinder, but may be formed in various shapes or materials in consideration of the type of cosmetic contents stored therein, usability, design elements, etc.

[0037] 2 and 3, a cylindrical or columnar coupling extension 12 may be formed along the central axis at the center of the interior of the cylindrical cup-shaped outer case 10. The coupling extension 12 extends to a certain height from the bottom of the outer case 10, and the lifting member 60 is coupled to cover the outside of the coupling extension 12. The outer case 10 and the lifting member 60 are fixed together when the inverted cylindrical cup-shaped rotating member 40 is gripped and rotated. A first fixed connecting portion 12a in the form of a vertical rib extending in the axial direction is formed on the outer circumferential surface of the coupling extension 12, and may be coupled to the lifting member 60. Here, the first fixed connecting portions (12a) are formed to protrude from the outer circumferential surface of the coupling extension portion (12) so as to be spaced apart at regular intervals in the circumferential direction, and it is preferable that the first fixed connecting portions (12a) are formed to be tapered toward the end (the upper end is tapered upward in FIG. 8) so that the outer case (10) and the lifting member (60) can be smoothly fitted together.

[0038] Meanwhile, a fixing member 14 may be inserted and coupled to the inside (on the inner peripheral surface) of the outer case 10. The fixing member 14 is ring-shaped (cylindrical in the drawing) with both sides open, and stably assembles and fixes the inner case 30 to the outer case 10 so that it does not separate from the outer case 10. At least a portion of the fixing member 14 is fixed and coupled to the inside of the outer case 10, and the remaining portion is exposed to the open side of the outer case 10.

[0039] One side (upper side in the figure) of the outer case 10 may further include an inverted cylindrical cup-shaped overcap 80 that opens or closes the rotating member 40. The overcap 80 is detachably fastened to the outer case 10 (the outer cylindrical portion) or the fixed body 14 so as to cover the rotating member 40. During use, the overcap 80 is separated from the outer case 10 or the fixed body 14 to expose the rotating member 40 to the outside, and during storage or carrying, it is connected to the outer case 10 or the fixed body 14 to protect the rotating member 40. In the rotary-dispensing cosmetic container according to one embodiment of the present invention, the fixed body (14) and the overcap (80) are shown as having threads formed on each of them and are screwed together, but this is not limited to this, and various types of connection structures may be used, such as connection using a protrusion and a groove or a recess, forced fitting, or undercut connection, as long as the overcap (80) can be easily attached and detached from the fixed body (14).

[0040] The rotary actuating member 20 is rotatably connected to the inside of the outer case 10 and rotates together with the rotary member 40, thereby rotating the actuating member 50. The rotary actuating member 20 serves to transmit the rotational motion of the rotary member 40 to the actuating member 50. An inner case 30 is inserted into the inner space of the rotary actuating member 20, and the actuating member 50 is fixedly connected to the center.

[0041] 2, the rotary actuating member 20 may comprise a tubular (particularly cylindrical) outer wall 22, a tubular (particularly cylindrical) inner wall 24 spaced apart from the outer wall 22 at a predetermined distance, and a connecting bottom plate 26 connecting the outer wall 22 and the inner wall 24. At least a portion of the inner case 30 is inserted into the space between the outer wall 22 and the inner wall 24, and the actuating member 50, the lifting member 60, and the connecting extension 12 of the outer case 10 are inserted inside the inner wall 24, and the connecting bottom plate 26 is attached to the bottom surface of the outer case 10.

[0042] The rotation actuating member 20 rotates together with the rotation member 40 when the rotation actuating member 20 is gripped and rotated, and a pulse-wave-shaped (specifically, curved plate-shaped with an arcuate cross section) first rotation connecting portion 22a is formed at an end (upper end in the figure) of the outer wall 22 of the rotation actuating member 20 to be coupled with the rotation member 40. The first rotation connecting portion 22a is spaced apart at regular intervals in the circumferential direction from the end of the outer wall 22 and extends to protrude toward the rotation member 40 (upward in the figure). It is preferable that the end (upper end) of the first rotation connecting portion 22a has at least one first guide inclined surface 22b formed thereon to allow the rotation actuating member 20 and the rotation member 40 to be smoothly fitted together.

[0043] A first detachable portion 22c is formed on the outer wall 22 of the rotation actuating member 20 and can be detachably connected to the second detachable portion 32 of the inner case 30. The first detachable portion 22c is preferably formed to protrude partially or continuously in the circumferential direction from the inner circumferential surface of the outer wall 22 of the rotation actuating member 20.

[0044] At least one engaging protrusion 24a is formed on the inner peripheral surface of the inner wall 24 of the rotary actuating member 20 to be coupled with the actuating member 50, thereby allowing the actuating member 50 to rotate together with the rotary actuating member 20. The engaging protrusions 24a are preferably formed on the inner peripheral surface of the inner wall 24 at regular intervals in the circumferential direction.

[0045] Meanwhile, a latching protrusion (28) is formed on the outer peripheral surface of the rotation actuating member (20) so as to protrude outward. As shown in FIG. 4, the latching protrusion (28) is latched onto the end of the fixed body (14), thereby preventing the rotation actuating member (20) from coming off the outer case (10).

[0046] The inner case (30) is detachably coupled to the rotary actuation member (20) when inserted into the inner space of the outer case (10), and the cosmetic contents can be stored in the inner space. One side of the inner case (30) is open, and the cosmetic contents are transferred to the rotary member (40) through the open portion. At this time, the cosmetic contents are moved linearly (along the central axis) by the lifting member (60), and are preferably solid cosmetics whose upper surface is scraped by the rotary member (40).

[0047] As shown in Figures 2 and 3, a second detachable portion (32) is formed on the outer circumferential surface of the inner case (30), and the second detachable portion (32) and the first detachable portion (22c) can be detachably coupled to each other. The second detachable portion (32) is preferably recessed in the circumferential direction of the outer circumferential surface of the inner case (30). In the rotary dispenser type cosmetic container according to one embodiment of the present invention, the first detachable portion (22c) is formed as a protrusion and the second detachable portion (32) is formed as a groove that are fitted together. However, this is not limited thereto. The first detachable portion (22c) and the second detachable portion (32) can both be formed as protrusions and hooked together. In addition, a first fastening protrusion (33) is formed on the outer circumferential surface of the inner case (30) and can be rotatably coupled to the rotating member (40).

[0048] Meanwhile, a lift guide protrusion (34) may be formed on the inner circumferential surface of the inner case (30). The lift guide protrusion (34) is coupled to the piston (70) (lift guide groove (74) on the outer circumferential edge thereof) to prevent the piston (70) and the cosmetic contents from rotating relative to the inner case (30). The lift guide protrusion (34) is preferably formed to extend in the movement direction of the piston (70) (direction along the central axis), and at least one pair of lift guide protrusions (34) is preferably formed and arranged facing each other. A first latch protrusion (36) (a circumferential rib-like protrusion in the illustration) is formed on the inner circumferential surface of the inner case (30), and at least a portion of the actuating member (50) may be attached to the upper surface thereof. As can be seen from FIGS. 4 and 5, the cosmetic contents are accommodated in the space between the upper inner circumferential surface of the outer wall of the inner case (30) and the upper surface of the piston (70). In the illustrated example, the lower part of the inner case (30) has a triple wall, between which the lower cylindrical part of the piston (70) is fitted. As shown in Fig. 4, the latch protrusion (36) is provided on the inner peripheral surface of the inner wall.

[0049] The rotating member (40) covers the open portion of the inner case (30) and is rotatably connected to the inner case (30). When the rotating member (40) is grasped and rotated by the user, the cosmetic contents contained in the inner case (30) are discharged to the outside.

[0050] The rotating member 40 has a discharge surface 42 that is exposed to the outside and comes into direct contact with a cosmetic tool or a user's fingers. The discharge surface 42 may have a discharge opening 42a formed therein for discharging the cosmetic contents contained in the inner case 30 to the outside. The discharge surface 42 is formed to be recessed from the periphery of the rotating member 40 toward the center (curved concave in FIG. 4) so ​​that the contents discharged from the inner case 30 do not drip off the periphery of the rotating member 40. Preferably, the discharge surface 42a is a linear hole extending from the center to the periphery of the discharge surface 42. Here, one side wall of the discharge opening 42a may be formed to be inclined at a certain angle (e.g., 5 to 60 degrees from the vertical) toward the rotation direction of the rotating member 40 to smoothly discharge the cosmetic contents. In the rotary-dispensing cosmetic container according to the embodiment of the present invention, the discharge outlet (42a) is shown as being in a linear shape extending long on the discharge surface (42), but this is not limited to this, and the shape, number, or position of the discharge outlet (42a) can be changed in various ways as long as the contents of the cosmetic can be easily discharged to the outside.

[0051] The rotating member 40 may be provided with a cutting blade 42b that scrapes the surface of the cosmetic contents as it rotates. The cutting blade 42b is a linear protrusion extending from the center of the rotating member 40 (directly below the center of the discharge surface 42) to the periphery, and is formed adjacent to and protruding from the discharge opening 42a toward the cosmetic contents contained in the inner case 30 located below it, and may be formed to extend in the same direction as the discharge opening 42a. Here, the cutting blade 42b is preferably tapered toward its end (tip) and tilted toward the rotation direction of the rotating member 40 (e.g., at an angle of 5 to 60 degrees from the vertical) in order to smoothly scrape the surface of the cosmetic contents for discharge.

[0052] A rib-shaped second fastening protrusion 43 extending a predetermined length in the circumferential direction is formed on the inner peripheral surface of the rotating member 40, and can be rotatably hooked and coupled to the first fastening protrusion 33 of the inner case 30. Of course, either the first fastening protrusion 33 or the second fastening protrusion 43 can be formed as a groove, and can be rotatably fitted to each other.

[0053] Meanwhile, the rotating member 40 is fixedly coupled to the rotating actuating member 20 and rotates the rotating actuating member 20. Pulse-wave-shaped second rotating connectors 44 may be formed at an end (lower end in the drawing) of the rotating member 40, and each may be fitted between the pulse-wave-shaped first rotating connectors 22a of the rotating actuating member 20. The first rotating connectors 22a and the second rotating connectors 44 are formed to extend in the direction of attachment / detachment of the inner case 30 and engage with each other to transmit the rotational motion of the rotating member 40 to the rotating actuating member 20. The first rotating connectors 22a and the second rotating connectors 44 may be formed to extend over a certain circumferential distance alternately at the ends of the rotating actuating member 20 and the rotating member 40 that face each other. Preferably, the second rotational coupling portions 44 are spaced apart at regular intervals in the circumferential direction from the end portions of the rotational member 40 and extend toward the rotational actuating member 20. At least one second guide inclined surface 44a is formed on each end portion of the second rotational coupling portions 44, and the second guide inclined surface 44a guides the assembly direction so that the second rotational coupling portions 44 are smoothly fitted between the first rotational coupling portions 22a when the rotational actuating member 20 and the rotational member 40 are coupled together.

[0054] Meanwhile, the inner case 30 and the rotating member 40 may further include a rotation direction control structure for controlling the rotation direction of the rotating member 40. That is, by adding a rotation direction control structure to each of the inner case 30 and the rotating member 40, the rotating member 40 can be rotated only in the ascending direction of the lifting member 60 and prevented from rotating in the descending direction of the lifting member 60, thereby increasing convenience of use. For example, one-way rotation protrusions (not shown) that transmit rotation in only one direction like a ratchet gear (a gear that transmits rotation in only one direction and not in the opposite direction) can be formed on the outer circumferential surface of the inner case 30 and the inner circumferential surface of the rotating member 40, respectively, so that they can mesh with each other.

[0055] The actuating member (50) is in the form of a cylinder with both sides open, and is disposed in the inner space of the outer case (10). It is connected to the rotary actuating member (20) and rotates together with the actuating member (50) to move the lifting member (60) linearly.

[0056] 4, the actuating member 50 may be inserted into the center of the rotary actuating member 20 and the inner case 30 and fixedly coupled to the rotary actuating member 20. At least one mating recess 54 is formed on the outer circumferential surface of the actuating member 50, into which the mating protrusion 24a of the rotary actuating member 20 is inserted, thereby allowing the actuating member 50 to rotate together with the rotary actuating member 20. The mating recesses 54 are preferably recessed and spaced apart at regular intervals in the circumferential direction on the outer circumferential surface of the actuating member 50. A rib-like second latch protrusion (56) extending within a certain range in the circumferential direction is formed on the outer peripheral surface of the actuating member (50), and as it is attached to the upper surface of the first latch protrusion (36) of the inner case (30), it can rotate stably without shaking relative to the inner case (30). Furthermore, when the inner case (30) is refilled, it can be separated from the rotating actuating member (20) as it moves together with the inner case (30).

[0057] The actuating member (50) is connected to the lifting member (60) while covering the outside of the latter. A screw thread is formed on the inner peripheral surface of the actuating member (50) and a screw thread is formed on the outer peripheral surface of the lifting member (60), so that they can be screwed together.

[0058] The lifting member (60) is screw-connected to the actuating member (50) and moves linearly within the internal space of the internal case (30), pushing the cosmetic contents up into the open portion of the internal case (30) in proportion to the rotation angle of the rotating member (40).

[0059] 2 and 3, the lifting member 60 may be formed of a hollow coupling portion 62 having a screw thread formed on its outer periphery and screw-coupled to the actuating member 50, and a support portion 64 extending outward from the end (the upper end in the drawing) of the coupling portion 62 and contacting one side of the piston 70 to push up the piston 70. Of course, the coupling portion 62 and the support portion 64 may be integrally injection molded, or may be separately injection molded, with the coupling portion 62 fixedly coupled to the center of the support portion 64.

[0060] The coupling portion 62 has a screw thread formed on its outer circumferential surface, which can be screw-coupled with a screw thread formed on the inner circumferential surface of the actuating member 50. The coupling portion 62 is fixedly coupled to the outside of the coupling extension portion 12 of the outer case 10, and the inner circumferential surface of the coupling portion 62 has a second fixed connecting portion 62a formed as a plateau-shaped protrusion extending in the axial direction, which is engaged with a first fixed connecting portion 12a of the outer case 10, which is also a plateau-shaped protrusion extending in the axial direction. The first fixed connecting portion 12a and the second fixed connecting portion 62a are formed to extend in the attachment / detachment direction of the inner case 30, and are engaged with each other to restrict the rotation of the lifting member 60 relative to the outer case 10. The first fixed connecting portions 12a and the second fixed connecting portions 62a may be alternately formed to protrude from the opposing surfaces of the outer case 10 and the lifting member 60. Here, the second fixed connecting portions 62a are formed to protrude from the inner peripheral surface of the coupling portion 62 at regular intervals in the circumferential direction, and the second fixed connecting portions 62a are preferably tapered toward their ends (i.e., the lower ends are tapered downward) so that the second fixed connecting portions 62a can easily enter the spaces between the first fixed connecting portions 12a.

[0061] Meanwhile, the support portion 64 is formed with a plurality of latch recesses 64a to be coupled with the piston 70, and the latch recesses 64a may be formed at regular intervals along the periphery of the support portion 64.

[0062] The piston (70) is disposed in the inner space of the inner case (30) and moves the cosmetic contents to the discharge port (42a) as it moves up and down together with the lifting member (60).

[0063] The piston 70 has a contact portion 72 formed on its periphery to be in close contact with the inner wall of the inner case 30, and the contact portion 72 has a lift guide groove 74 formed therein to be engaged with the lift guide protrusion 34 of the inner case 30. The piston 70 also has a latch protrusion 76 formed on its inner side to be engaged with the latch groove 64a of the lift member 60. This allows the piston 70 and the cosmetic contents to move stably and linearly along the lift guide protrusion 34 within the inner case 30 without rotating.

[0064] As described above, in the refilling process of the rotary-dispensing cosmetic container according to one embodiment of the present invention, in which the inner case (30) and the rotary actuating member (20) are separated and fastened, the first rotary connecting portion (22a) of the rotary actuating member (20) and the second rotary connecting portion (44) of the rotary member (40) are fitted together so as to mesh with each other, and at the same time, the first fixed connecting portion (12a) of the outer case (10) and the second fixed connecting portion (62a) of the lifting member (60) are fitted together so as to mesh with each other. Therefore, the amount of cosmetic content dispensed can be easily adjusted by the rotation angle of the rotating member (40), improving convenience of use. Furthermore, the inner case (30) can be detached from the outer case (10) after the cosmetic content has been completely consumed and replaced or refilled, reducing the economic burden on the user and waste of resources. Furthermore, the rotating member (40), the inner case (30), and the components connected thereto can be easily separated and replaced at the same time by pulling out the rotating member (40) from the outer case (10) or inserting the inner case (30).

[0065] 5 to 8 are diagrams illustrating the operation and refilling processes of a rotary dispenser type cosmetic container according to an embodiment of the present invention. The use and refilling processes of a rotary dispenser type cosmetic container according to an embodiment of the present invention will be described with reference to these figures.

[0066] FIG. 5 is a cross-sectional view illustrating a state in which a cosmetic container is rotated according to one embodiment of the present invention, FIG. 6 is a cross-sectional view illustrating a state in which a cosmetic container is operated according to one embodiment of the present invention to eject the contents of the cosmetic to the outside, FIG. 7 is a perspective view illustrating a state in which an inner case of a cosmetic container according to one embodiment of the present invention is separated, and FIG. 8 is a perspective view illustrating a state in which an inner case of a cosmetic container according to one embodiment of the present invention is inserted.

[0067] To use the rotary dispenser type cosmetic container according to the embodiment of the present invention, the overcap (80) is separated from the outer case (10) or the fixed body (14) to expose the rotary member (40) to the outside.

[0068] 5, when the rotating member (40) is rotated in either direction relative to the outer case (10), the rotating actuating member (20) coupled to the rotating member (40) and the actuating member (50) connected to the rotating actuating member (20) rotate together, while the rotation of the lifting member (60) is restricted by the coupling extension (12) of the outer case (10). As a result, the lifting member (60) screw-coupled to the actuating member (50) gradually moves upward in proportion to the distance the rotating member (40) has rotated, and as the piston (70) is lifted by the lifting member (60), the cosmetic contents are pushed up toward the discharge opening (42a) of the rotating member (40).

[0069] At the same time, as the cutting blade (42b) of the rotating member (40) rotates, it scrapes off the upper surface of the cosmetic contents, and as shown in Figure 6, the cosmetic contents scraped off by the cutting blade (42b) are discharged through the discharge opening (42a).

[0070] The cosmetic contents dispensed onto the dispensing surface 42 of the rotating member 40 are then applied by pressing them onto a makeup tool such as a puff (not shown) and then evenly spreading the contents onto the skin. After applying makeup, the rotating member 40 is covered with the overcap 70 and connected to the outer case 10 or fixed body 14 for storage or carrying.

[0071] On the other hand, when all the cosmetic contents contained in the inner case 30 have been used, the inner case 30 is replaced and used. As shown in Figure 7, the rotating member 40 is grasped and pulled out from the outer case 10 to separate the components connected to the rotating member 40, i.e., the inner case 30, the actuating member 50, the lifting member 60, and the piston 70. At this time, the first detachable portion 22c of the rotating actuating member 20 is disengaged from the second detachable portion 32 of the inner case 30. Subsequently, the second rotational coupling portion 44 of the rotating member 40 is disengaged from the first rotational coupling portion 22a of the rotating actuating member 20, and simultaneously, the second fixed coupling portion 62a of the lifting member 60 is disengaged from the first fixed coupling portion 12a of the outer case 10.

[0072] Thereafter, as shown in FIG. 8, the inner case (30) connected to the rotating member (40), the operating member (50), the lifting member (60), and the piston (70) are completely separated from the outer case (10), and then a new rotating member (40), inner case (30), the operating member (50) connected to the inner case (30), the lifting member (60), and the piston (70) are inserted into the inner space of the outer case (10) to perform replacement. At this time, the second rotary connecting portion (44) of the rotary member (40) is inserted between the first rotary connecting portions (22a) of the rotary operating member (20), and at the same time, the second fixed connecting portion (62a) of the lifting member (60) is inserted between the first fixed connecting portions (12a) of the outer case (10), and successively, the first detachable portion (22c) of the rotary operating member (20) and the second detachable portion (32) of the inner case (30) are fastened together.
