Description

Technical Field

[0001] One aspect of the present disclosure relates to a cosmetic container, and more particularly, to a rotation-discharge type cosmetic container to conveniently use the cosmetic content while discharging the cosmetic content through a rotation operation. Background Art

[0002] Generally, women use various cosmetics to make their appearance more beautiful. Among these cosmetics, the purpose of using makeup is to make the skin more beautiful by making the appearance more beautiful.

[0003] Color cosmetics are divided into base makeup for even skin tone and covering blemishes and spot makeup for enhancing the three-dimensional effect of lips, eyes, nails, etc. Base makeup includes base makeup, foundation, loose powder, etc., and spot makeup includes lipstick, eyeliner, mascara, etc.

[0004] Foundation refers to a cosmetic product used to naturally cover spots or blemishes on exposed skin such as the face, or to make the skin appear clean, bright, or smooth and tender. When applying makeup using foundation, the foundation is evenly applied to the skin without caking by using a cosmetic puff.

[0005] Generally, the foundation is contained and stored in a wide and flat cosmetic container, and a powder puff is placed together in the cosmetic container. The user opens the lid of the cosmetic container, holds the powder puff contained in the upper part of the lid of the inner container, opens the lid of the inner container, dips the powder puff into the foundation cosmetic content, and then applies the content on the skin for use.

[0006] However, since conventional cosmetic containers need to be used with the container lid open, the cosmetic contents may be completely exposed to the air, which may easily introduce foreign matter, and since the powder puff that has been in contact with the skin during use repeatedly contacts the cosmetic contents, the cosmetic contents may be contaminated by bacteria, viruses, fungi, etc., which may cause skin problems or may shorten the use time. In addition, since conventional cosmetic containers are configured so that the cosmetic contents are dipped and used by using a makeup tool such as a powder puff or using fingers, the amount of the cosmetic contents used may not be consistently controlled, thereby wasting the cosmetic contents and causing difficulty in use.

[0007] Therefore, cosmetic containers have been developed to minimize deterioration and contamination during use of cosmetics, to allow for convenient use, and to consistently control the amount of cosmetic contents discharged.

[0008] As prior arts having the above-described structure, cosmetic containers have been 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 are described below.

[0009] Prior art 1 includes: an inner housing having an internal space; a rotation bezel rotatably coupled to an upper portion of the inner housing and having a discharge hole; a rotating member located in the internal space and coupled to the rotation bezel to rotate integrally with the rotation baffle; and a piston located in the internal space and coupled to the rotating member to rise and fall with the rotation of the rotating member.

[0010] Prior art 2 includes: a main body having an internal space; a dial rotatably connected to an upper portion of the main body and including a discharge hole through which contents are discharged and a cutter for crushing the contents; a screw located below the dial in the internal space to rotate integrally with the dial; and a piston threadedly connected to the periphery of the screw to rise and fall within the internal space by rotation of the screw.

[0011] However, since neither of the prior arts 1 nor 2 has a separate inner shell refilling structure, the entire cosmetic container needs to be discarded after the contents stored in the inner shell are used up, which may waste resources and may pollute the environment due to the discarded container.

[0012] Therefore, it is necessary to develop a stick-type cosmetic container so that some parts of the cosmetic container are replaceable, thereby reducing the economic burden of the user, reducing resource waste and environmental pollution, and allowing convenient replacement of some parts.

In addition, it should be understood that the position or configuration of the individual elements in each disclosed embodiment may be modified without departing from the thought and scope of the present disclosure.

[0038] Therefore, the detailed description set forth below is not intended to be limiting, and the scope of the present disclosure is limited only by the appended claims and the full scope of equivalents to which the claims are entitled, if appropriate. Like reference numerals in the drawings refer to components having the same or similar functions in several aspects.

[0039] Considering the functions according to the present disclosure, the most recently widely used common terms are selected in the present disclosure as much as possible, but this may change according to the intention of those skilled in the art, precedents, the emergence of new technologies, etc. In some cases, the applicant may arbitrarily select the term, and in this case, its meaning will be explained in detail in the relevant description of the present disclosure. Therefore, the terms used in the present disclosure will be defined based on the meaning of the terms and the contents throughout the present disclosure, rather than simply based on the names of the terms.

[0040] In the present disclosure, when a component "includes" some elements, it does not exclude other elements but may further include other elements unless otherwise specifically stated. Hereinafter, a rotary discharge type cosmetic container according to an embodiment of the present disclosure is described in detail with reference to the accompanying drawings.

[0041] Figure 1 is a perspective view of a cosmetic container according to one embodiment of the present disclosure. Figure 2 is an exploded perspective view of a cosmetic container according to one embodiment of the present disclosure when viewed from above. Figure 3 is an exploded perspective view of a cosmetic container according to one embodiment of the present disclosure when viewed from below. Figure 4 is a cross-sectional view of a cosmetic container according to one embodiment of the present disclosure.

[0042] As shown, the rotary discharge type cosmetic container according to an embodiment of the present disclosure is configured to include an outer housing 10 , a rotary operating member 20 , an inner housing 30 , a rotating member 40 , an operating member 50 , a lift member 60 , and a piston 70 .

[0043] Hereinafter, the rotary discharge type cosmetic container according to the embodiment of the present disclosure will be described as follows with respect to each component respectively.

[0044] The outer shell 10 has a hard cylindrical shape, one side of which is open and a space of a predetermined size is formed therein, wherein the rotation operation member 20 and the inner shell 30 are at least partially inserted and coupled to the inner space. The outer shell 10 is not limited to the hard cylindrical shape, and may be formed in various shapes or materials in consideration of the type of cosmetic contents stored therein, usability, design factors, etc.

[0045] like Figure 2 and Figure 3 As shown, a coupling extension 12 may be formed at the inner center of the outer shell 10. The coupling extension 12 extends from the bottom surface of the outer shell 10 to a predetermined height, and is coupled to the lifting member 60 while surrounding the outer side surface of the lifting member 60. When the rotating member 40 rotates, the outer shell 10 and the lifting member 60 remain fixed together, wherein a first fixed connection portion 12a may be formed on the outer periphery of the coupling extension 12 to be coupled to the lifting member 60. The first fixed connection portions 12a may protrude along the outer periphery of the coupling extension 12 while being spaced apart at regular intervals, and the first fixed connection portions 12a may be sharper toward their ends so that the outer shell 10 is smoothly assembled to the lifting member 60.

[0046] On the other hand, the holder 14 can be coupled to the outer shell 10. The holder 14 has an annular shape with both sides open to stably assemble and fix the inner shell 30 to prevent it from being separated from the outer shell 10, wherein at least a portion of the holder 14 is fixedly coupled to the outer shell 10, and the remaining portion is exposed to the open side of the outer shell 10.

[0047] A cap 80 for opening or closing the rotating member 40 may also be provided on one side of the outer shell 10. The cap 80 is detachably fastened to the outer shell 10 or the holder 14 while covering the rotating member 40, and is separated from the outer shell 10 or the holder 14 when in use to expose the rotating member 40 to the outside, and is connected to the outer shell 10 or the holder 14 to protect the rotating member 40 when stored or carried. A rotary discharge type cosmetic container according to an embodiment of the present disclosure shows that threads are formed on the holder 14 and the cap 80 and are connected together by threads. However, the present disclosure is not limited thereto, and various coupling structures such as coupling using protrusions and grooves, forced fitting coupling, and undercut coupling may exist within the scope of allowing the cap 80 to be easily attached to and removed from the holder 14.

[0048] The rotary operating member 20 is rotatably coupled to the inside of the outer housing 10 to rotate the operating member 50 while rotating together with the rotary member 40. The rotary operating member 20 is used to transmit the rotational motion of the rotary member 40 to the operating member 50, wherein the inner housing 30 can be inserted into the inner space of the rotary operating member 20, and the operating member 50 can be fixedly coupled to the center of the rotary operating member 20.

[0049] like Figure 2 As shown in the partial enlarged view of FIG. 1 , the rotary operating member 20 may include an outer wall 22, an inner wall 24 spaced apart at regular intervals inward from the outer wall 22, and a connecting bottom plate 26 for connecting the outer wall 22 and the inner wall 24 to each other. At least a portion of the inner housing 30 is inserted into the space between the outer wall 22 and the inner wall 24, the operating member 50, the lifting member 60, and the connecting extension 12 of the outer housing 10 are inserted into the inner wall 24, and the connecting bottom plate 26 is located on the bottom surface of the outer housing 10.

[0050] When the rotating member 40 rotates, the rotating operating member 20 rotates together with the rotating member 40, wherein a first rotating connection portion 22a may be formed at the end of the outer wall 22 of the rotating operating member 20 to be coupled with the rotating member 40. The first rotating connection portions 22a may extend toward the rotating member 40 while being spaced apart at regular intervals along the circumference of the end of the outer wall 22, and at least one first guide slope 22b may be formed at the end of the first rotating connection portion 22a so that the rotating operating member 20 is smoothly assembled to the rotating member 40.

[0051] In addition, a first detachable portion 22c may be formed on the outer wall 22 of the rotary operation member 20 to be detachably coupled to the second detachable portion 32 of the inner housing 30. The first detachable portion 22c may partially or continuously protrude along the inner circumference of the outer wall 22 of the rotary operation member 20.

[0052] At least one fitting protrusion 24a may be formed on the inner circumference of the inner wall 24 of the rotary operating member 20, and the fitting protrusion is coupled with the operating member 50, so that the operating member 50 can rotate together with the rotary operating member 20. The fitting protrusions 24a may be formed to protrude at regular intervals along the inner circumference of the inner wall 24.

[0053] On the other hand, the locking protrusion 28 may protrude outward from the outer periphery of the rotation operation member 20, and as shown in FIG. Figure 4 As shown, the locking protrusion 28 may be configured to be locked on the end of the holder 14 , thereby preventing the rotary operating member 20 from being separated from the outer housing 10 .

[0054] The inner housing 30 can be inserted into the space inside the outer housing 10 and detachably coupled to the rotating operating member 20, and the cosmetic content can be accommodated in the inner space. The inner housing 30 has an open side through which the cosmetic content moves to the rotating member 40. The cosmetic content may be a solid cosmetic that is moved in a straight line by the lifting member 60 and has an upper surface cut by the rotating member 40.

[0055] like Figure 2 and Figure 3 As shown, a second detachable portion 32 may be formed on the outer periphery of the inner shell 30 to be detachably coupled with the first detachable portion 22c. The second detachable portion 32 may be recessed along the outer periphery of the inner shell 30. A rotary discharge type cosmetic container according to an embodiment of the present disclosure shows that the first detachable portion 22c is formed as a protrusion and the second detachable portion 32 is formed as a groove so as to be assembled together. However, the present disclosure is not limited thereto, and the first detachable portion 22c and the second detachable portion 32 may both be formed as protrusions so as to engage with each other. In addition, the first fastening protrusion 33 may protrude from the outer periphery of the inner shell 30 to be rotatably coupled with the rotating member 40.

[0056] On the other hand, the lifting guide protrusion 34 may protrude from the inner circumference of the inner housing 30. The lifting guide protrusion 34 is coupled to the piston 70 to prevent the piston 70 and the cosmetic contents from rotating relative to the inner housing 30. The lifting guide protrusion 34 may extend in the moving direction of the piston 70, and may be formed as at least one pair arranged facing each other. In addition, the first locking protrusion 36 may protrude from the inner circumference of the inner housing 30, and at least a portion of the operating member 50 may be located on the top of the first locking protrusion.

[0057] The rotating member 40 is rotatably coupled with the inner case 30 while covering the opening portion of the inner case 30 to discharge the cosmetic content contained in the inner case 30 to the outside when the user rotates the rotating member.

[0058] The rotating member 40 may be formed with a discharge surface 42 exposed to the outside to directly contact the makeup tool or the user's finger, and a discharge port 42a for discharging the cosmetic contents contained in the inner housing 30 to the outside may be formed in the discharge surface 42. The discharge surface 42 may be recessed toward the center from the edge of the rotating member 40 to prevent the contents discharged from the inner housing 30 from flowing downward to the periphery of the rotating member 40, and the discharge port 42a may be a hole having a long straight line shape extending from the center of the discharge surface 42 to the edge portion. One side wall of the discharge port 42a may be inclined at a predetermined angle in the rotation direction of the rotating member 40 to smoothly discharge the cosmetic contents. The rotary discharge type cosmetic container according to the embodiment of the present disclosure is exemplified by a long straight line extending on the discharge surface 42 in which the discharge port 42a extends. However, the present disclosure is not limited thereto, and the shape, number or position of the discharge port 42a may be variously changed within a range that allows the cosmetic contents to be easily discharged to the outside.

[0059] The rotating member 40 may be provided with a cutting blade 42b for cutting the surface of the cosmetic content while rotating. The cutting blade 42b refers to a protrusion having a straight line shape and extending from the center to the edge of the rotating member 40, and may be located near the lower portion of the discharge port 42a to protrude toward the cosmetic content contained in the inner housing 30 and extend in the same direction as the discharge port 42a. The cutting blade 42b may become sharper toward its tip and be inclined in the rotation direction of the rotating member 40 so as to smoothly grind the surface of the cosmetic content and discharge it.

[0060] In addition, the second fastening protrusion 43 may protrude from the inner circumference of the rotating member 40 to rotatably engage with the first fastening protrusion 33 of the inner housing 30. Alternatively, one of the first fastening protrusion 33 and the second fastening protrusion 43 may be formed as a groove to rotatably engage with each other.

[0061] On the other hand, the rotating member 40 is fixedly coupled to the rotating operating member 20 so that the rotating operating member 20 rotates, wherein a second rotating connection portion 44 may be formed at the end of the rotating member 40 to be assembled to the first rotating connection portion 22a of the rotating operating member 20. The first rotating connection portion 22a and the second rotating connection portion 44 extend in the disassembly direction of the inner housing 30 to engage with each other, thereby transmitting the rotational motion of the rotating member 40 to the rotating operating member 20. The first rotating connection portion 22a and the second rotating connection portion 44 may extend alternately from the opposite ends of the rotating operating member 20 and the rotating member 40 by predetermined sections, respectively. The second rotating connection portion 44 may extend toward the rotating operating member 20 while being spaced apart at regular intervals along the circumferential end of the rotating member 40. At least one second guide slope 44a is formed at the end of the second rotating connection portion 44, and the second guide slope 44a guides the assembly direction so that when the rotating operating member 20 and the rotating member 40 are coupled to each other, the second rotating connection portion 44 is smoothly inserted between the first rotating connection portion 22a.

[0062] On the other hand, the inner housing 30 and the rotating member 40 may further include a rotation direction control structure for controlling the rotation direction of the rotating member 40. In other words, the rotation direction control structure is added to the inner housing 30 and the rotating member 40, respectively, so as to allow the rotating member 40 to rotate only in the upward direction of the lifting member 60 and prevent the rotating member 40 from rotating in the downward direction of the lifting member 60, thereby improving the convenience of use. For example, a one-way rotating protrusion (not shown) for transmitting only rotation in one direction, such as a ratchet (a gear that transmits only rotation in one direction but not movement in the opposite direction) gear, may be formed on the outer periphery of the inner housing 30 and the inner periphery of the rotating member 40, respectively, to interlock with each other.

[0063] The operating member 50 has a cylindrical shape with two sides opened, and is disposed in the inner space of the outer shell 10 , and is connected to and rotates with the rotating operating member 20 , so that the lifting member 60 moves in a straight line.

[0064] like Figure 4 As shown, the operating member 50 can be inserted into the center of the rotary operating member 20 and the inner housing 30, thereby being fixedly coupled to the rotary operating member 20. At least one assembly groove 54 can be formed on the outer periphery of the operating member 50, and the insertion protrusion 24a of the rotary operating member 20 can be inserted therein, so that the operating member 50 can rotate together with the rotary operating member 20. The assembly groove 54 can be recessed at regular intervals along the outer periphery of the operating member 50. In addition, the second locking protrusion 56 can protrude from the outer periphery of the operating member 50 and be located on the top of the first locking protrusion 36 of the inner housing 30, thereby stably rotating relative to the inner housing 30 without shaking, and separating from the rotary operating member 20 while moving together with the inner housing 30 when the inner housing 30 is refilled.

[0065] The operating member 50 is coupled thereto while surrounding the outer side of the lifting member 60 , wherein a thread may be formed on the inner circumference of the operating member 50 , and a thread is formed on the outer circumference of the lifting member 60 , thereby being thread-coupled to each other.

[0066] The lift member 60 is threadably coupled to the operating member 50 , and moves linearly in the inner space of the inner case 30 , thereby pushing the cosmetic contents upward toward the opening portion of the inner case 30 in proportion to the rotation angle of the rotating member 40 .

[0067] like Figure 2 and Figure 3 As shown, the lifting member 60 may include: a hollow coupling portion 62 having a thread formed on its outer circumference and threadedly coupled to the operating member 50; and a support portion 64 extending outward from the end of the coupling portion 62 and in close contact with one surface of the piston 70 to push the piston 70 upward. The coupling portion 62 and the support portion 64 may be integrally injection molded, or may be separately injection molded so that the coupling portion 62 is fixedly coupled to the center of the support portion 64.

[0068] A thread may be formed on the outer periphery of the coupling portion 62 to be threadedly coupled with a thread formed on the inner periphery of the operating member 50. The coupling portion 62 is fixedly coupled to the outer side of the coupling extension portion 12 of the outer housing 10, wherein a second fixed connection portion 62a may be formed on the inner periphery of the coupling portion 62 to be assembled to the first fixed connection portion 12a of the outer housing 10. The first fixed connection portion 12a and the second fixed connection portion 62a extend along the disassembly direction of the inner housing 30 and engage with each other to limit the rotation of the lifting member 60 relative to the outer housing 10. The first fixed connection portion 12a and the second fixed connection portion 62a may alternately protrude from the opposite surfaces between the outer housing 10 and the lifting member 60. The second fixed connection portion 62a may protrude while being spaced apart at regular intervals along the inner periphery of the coupling portion 62, and the second fixed connection portion 62a may be sharper toward its end to allow the second fixed connection portion 62a to easily enter the space between the first fixed connection portions 12a.

[0069] On the other hand, the support portion 64 is formed with locking grooves 64 a to be coupled with the piston 70 , wherein a plurality of locking grooves 64 a may be spaced apart at regular intervals along the edge of the support portion 64 .

[0070] The piston 70 is disposed in the inner space of the inner housing 30 to move the cosmetic content to the discharge port 42 a while being lifted together with the lift member 60 .

[0071] A close contact portion 72 may be formed on the edge of the piston 70 to be in close contact with the inner wall of the inner housing 30, a lifting guide groove 74 may be formed in the close contact portion 72 to be coupled with the lifting guide protrusion 34 of the inner housing 30, and a locking protrusion 76 may be formed inside the piston 70 to be coupled with the locking groove 64a of the lifting piece 60. Therefore, the piston 70 and the cosmetic content can stably move straight along the lifting guide protrusion 34 within the inner housing 30 without rotating.

[0072] As described above, in the rotary discharge type cosmetic container according to one embodiment of the present disclosure, during the refilling process in which the inner shell 30 and the rotary operating member 20 are separated and fastened, the first rotary connection portion 22a of the rotary operating member 20 is engaged and assembled with the second rotary connection portion 44 of the rotary member 40, and the first fixed connection portion 12a of the outer shell 10 is engaged and assembled with the second fixed connection portion 62a of the lifting member 60. Therefore, the discharge amount of the cosmetic content can be easily controlled according to the rotation angle of the rotary member 40, thereby improving the convenience of use, and the inner shell 30 in which the cosmetic content is completely exhausted can be refilled from the outer shell 10, thereby reducing the economic burden and resource waste of the user, and the rotary member 40 can be pulled out or the inner shell 30 can be inserted relative to the outer shell 10, so that the rotary member 40, the inner shell 30 and the components connected thereto can be conveniently separated and replaced at the same time.

[0073] Figures 5 to 8 is a diagram illustrating an operation process and a refilling process of a rotary discharge type cosmetic container according to an embodiment of the present disclosure. Figures 5 to 8 A use process and a refilling process of the rotary discharge type cosmetic container according to an embodiment of the present disclosure are described.

[0074] Figure 5 is a sectional view illustrating a rotating operation of a cosmetic container according to an embodiment of the present disclosure. Figure 6 is a sectional view illustrating a state in which a cosmetic container is operated to discharge the contents of cosmetics to the outside according to one embodiment of the present disclosure. Figure 7 is a perspective view illustrating a state in which an inner case of a cosmetic container is separated according to an embodiment of the present disclosure. Figure 8 is a perspective view illustrating a state in which an inner case of a cosmetic container is inserted according to one embodiment of the present disclosure.

[0075] In order to use the rotary discharge type cosmetic container according to an embodiment of the present disclosure, the cap 80 is separated from the outer body 10 or the holder 14 to expose the rotating member 40 to the outside.

[0076] Afterwards, if Figure 5As shown, when the rotating member 40 rotates in one direction relative to the outer shell 10, the rotating operating member 20 coupled to the rotating member 40 and the operating member 50 connected to the rotating operating member 20 rotate together, and the rotation of the lifting member 60 is restricted by the coupling extension 12 of the outer shell 10. Therefore, the lifting member 60 threadedly coupled to the operating member 50 gradually moves upward in proportion to the rotation range of the rotating member 40, and the piston 70 is lifted by the lifting member 60, thereby pushing the cosmetic content upward toward the discharge port 42a of the rotating member 40.

[0077] At the same time, the cutting blade 42b of the rotating member 40 rotates to cut the upper surface of the cosmetic content, so that the cosmetic content cut by the cutting blade 42b is discharged through the discharge port 42a, as shown in FIG. Figure 6 shown.

[0078] After that, by using a makeup tool such as a powder puff (not shown), the cosmetic contents discharged through the discharge surface 42 of the rotating member 40 are dipped and evenly applied on the skin for makeup. After the makeup is completed, the rotating member 40 is covered by the cap 80 and connected to the outer shell 10 or the holder 14 for storage or carrying.

[0079] In addition, when the cosmetic contents contained in the inner shell 30 are all used up, the inner shell 30 is replaced and used again. Figure 7 As shown, the rotating member 40 is pulled out from the outer housing 10, thereby separating the components connected to the rotating member 40, that is, the inner housing 30, the operating member 50, the lifting member 60 and the piston 70. At this time, the first detachable portion 22c of the rotating operating member 20 is disassembled from the second detachable portion 32 of the inner housing 30, the second rotating connection portion 44 of the rotating member 40 continues to be separated from the first rotating connection portion 22a of the rotating operating member 20, and the second fixed connection portion 62a of the lifting member 60 is separated from the first fixed connection portion 12a of the outer housing 10.

[0080] Afterwards, if Figure 8 As shown, the inner housing 30, the operating member 50, the lifting member 60 and the piston 70 connected to the rotating member 40 are completely separated from the outer housing 10, and then the new rotating member 40 and the inner housing 30, the operating member 50, the lifting member 60 and the piston 70 connected to the inner housing 30 are inserted into the inner space of the outer housing 10 for replacement. While the second rotating connection portion 44 of the rotating member 40 is inserted between the first rotating connection portions 22a of the rotating operating member 20, the second fixed connection portion 62a of the lifting member 60 is inserted between the first fixed connection portions 12a of the outer housing 10, and the first detachable portion 22c of the rotating operating member 20 and the second detachable portion 32 of the inner housing 30 are continuously connected to each other.
