Description

Technical Field

[0001] The present invention relates to a cosmetic case having a refill structure, and more particularly, to a cosmetic case having a refill structure in which a content container, a discharge mechanism, an inner lid, and an operation button move up and down from a container body by rotating an outer lid, thereby facilitating use or replacement. Background Art

[0002] In today's modern society, with the rapid diversification trend of the times, people of all ages use cosmetics according to their needs. In particular, women use various types and colors of cosmetic products and cosmetic tools, and through the research and development of cosmetic-related companies, various high-quality cosmetic products and tools are put on the market every day.

[0003] According to the purpose of use, cosmetics are classified into, for example, facial cleansing cosmetics for removing sebum, waste, and contaminants on the skin surface, base cosmetics for appropriately supplying moisture and oil to the skin, makeup cosmetics for expressing beautiful colors, hair cosmetics for protecting hair and providing nutrition and removing foreign substances from the hair or scalp, and perfumes obtained by dissolving aromatic materials in alcohol or the like and used for giving others a fragrance.

[0004] In addition, as people's interest in the stability of cosmetic ingredients and skin beauty increases due to the improvement of living standards, cosmetics are made of natural raw materials. However, since no preservatives are added to the above-mentioned cosmetics in order to reduce irritation to the skin, the risk of deterioration is relatively high compared to cosmetics made of chemical raw materials. For example, when bacteria penetrate due to contact with external air during use or when the ingredients are oxidized due to contact with air, cosmetics made of natural raw materials may be contaminated or deteriorated.

[0005] In addition, among the above-mentioned cosmetics, in order to store and use cosmetics in the form of liquids or gels such as lotions, creams, gels, shampoos, and conditioners, a container having a simple opening and closing function is usually used. The cosmetics are taken out of the container using a spatula or fingers and applied to the skin or hair. However, the above-mentioned conventional container cannot constantly control the amount of discharged cosmetics, so cosmetics are wasted.

[0006] Therefore, a pump-type cosmetic container has been developed, which minimizes the contact between cosmetics and external air and is conveniently used to constantly control the discharged amount of cosmetics.

[0007] The pump-type cosmetic container includes: a container body configured to accommodate contents; a pressurizing pump disposed in an opening of the container body and operated by pressing; and a nozzle head connected to an upper portion of the container body and also connected to the pressurizing pump, wherein when the nozzle head exposed to the outside is pressed downward, a predetermined amount of the contents accommodated in the container body is discharged to the outside through a pumping operation of the pressurizing pump.

[0008] According to the above pump-type cosmetic container, contact between the contents accommodated in the container body and external air is prevented. Since the contents are not excessively discharged through the discharge port of the nozzle, it is economical, and since the cosmetic container can be operated even when the container body is placed on the floor, it is convenient to use.

[0009] However, in a conventional cosmetic container, during storage or transportation, due to the user's carelessness, the button may be accidentally pressed, and the contents accommodated in the container may be discharged to the outside. As a result, relatively expensive cosmetics are wasted and the surrounding area is soiled by the discharged contents.

[0010] In addition, a conventional cosmetic container is stored or transported in a state where the discharge port of the button for discharging the contents to the outside is completely open. Therefore, when foreign matter is introduced into the open discharge port, the container is contaminated, and the contaminated contents are discharged and used, thereby causing a health-hazardous situation.

[0011] To solve the above problems, Korean Patent Registration No. 10-1267966 (hereinafter referred to as "the related art") discloses an airless pump cosmetic container having a retractable operation button. The above related art is configured such that the operation button of the airless pump appears and disappears after moving up and down on the upper side of the cosmetic container, and thus, the operation button is completely inserted into the container to prevent it from protruding to the outside when not in use due to carrying and storage, thereby preventing accidental operation caused by carelessness or the like to ensure safety, and promoting the operation by pumping by protruding the operation button to the outside during use.

[0012] However, since the related art does not have a separate internal refill structure, the entire cosmetic container needs to be discarded after all the contents stored in the container are used. Therefore, resources are wasted, and environmental pollution is accelerated due to the discarded containers.

[0013] Therefore, it is necessary to develop a cosmetic container that can conveniently refill the inner container containing the contents while preventing accidental operation of the operation button and contamination of the contents.

[0022] In addition, the refill guiding grooves and the refill guiding protrusions may be respectively formed as straight lines on the inner circumference of the lifting mechanism and the outer circumference of the inner lid along the direction in which the content container is inserted or separated.

[0023] In addition, one end of the refill guiding groove may be open, and guiding inclined surfaces for guiding the insertion of the refill guiding protrusions may be formed on two side walls of the open part.

[0024] In addition, the guiding slope can be inclined at a predetermined angle in the outward direction of the refilling guiding groove.

[0025] In addition, the lifting mechanism can be formed with friction protrusions on its outer periphery, so as to generate friction between the lifting mechanism and the inner periphery of the container body while being in close contact with the inner periphery of the container body.

[0026] In addition, an inlet portion can be formed in the content container, and the inlet portion is threadedly connected to the inner cap.

[0027] In addition, the discharging mechanism can include a pump for discharging the content by pumping.

[0028] In addition, a guiding straight hole can be formed in the inner cap, and a guiding straight protrusion can be formed in the operation button, so as to fix them to each other.

[0030] In addition, a protrusion portion can be formed on the operation button, and an anti-pressing step can be formed on the outer cap, so that when the operation button is inserted into the outer cap, the protrusion portion can be located at the upper end of the anti-pressing step.

[0031] In addition, the content container, the discharging mechanism, the inner cap and the operation button can be separated from the container body and the outer cap simultaneously, or inserted into the inner spaces of the container body and the outer cap simultaneously.

[0032] According to an embodiment of the present invention, the content container, the discharging mechanism, the inner cap and the operation button are lifted and lowered within a predetermined range by rotating the outer cap, and a part of them is pulled out or pulled into the container body, thereby facilitating the use convenience, and preventing the operation button from being operated by an external force regardless of the user's intention when carrying or storing.

[0033] According to an embodiment of the present invention, when the content stored in the content container is exhausted, it is possible to prevent the entire cosmetic case from being discarded, and only the content container combined with the discharging mechanism, the inner cap and the operation button can be replaced from the container body, thereby reducing the economic burden on the user and reducing resource waste and environmental pollution.

[0034] According to an embodiment of the present invention, the content container, the discharging mechanism, the inner cap and the operation button that are lifted and lowered together with the container body can be easily separated after being pulled out from the container body, and can be easily fixed after being pushed into the inner space of the container body, so that the refilling operation can be carried out more smoothly.

[0047] When a part of the present invention "comprises" an element, the above expression does not exclude other elements, and other elements may further be included, unless otherwise specifically stated.

[0048] Hereinafter, a cosmetic case having a refill structure according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0049] Figure 1 is a perspective view showing a cosmetic case according to an embodiment of the present invention. Figure 2 is an exploded perspective view showing a cosmetic case according to an embodiment of the present invention. Figure 3 is a cross-sectional view showing a cosmetic case according to an embodiment of the present invention.

[0050] As shown in the figure, a cosmetic case having a refill structure according to an embodiment of the present invention may include a container body 10, an outer cover 20, a lifting mechanism 30, a content container 40, a discharging mechanism 50, an inner cover 60, and an operation button 70.

[0051] Each component of the cosmetic case having a refill structure according to an embodiment of the present invention will be described below.

[0052] The container body 10 has a rigid cylindrical shape with one side open, and together with the outer cover 20, defines the appearance of the container of the cosmetic case. The container body 10 is not limited to a rigid cylinder, and may be formed in various shapes and made of various materials in consideration of the type of content stored therein, usability, design factors, etc. However, preferably, it has a relatively narrow width and a relatively long length so that the user can easily grasp the container body 10.

[0053] As Figure 2As shown, a connecting portion 12 is formed in the container body 10, and the connecting portion 12 can extend from one end of the container body 10 and be inserted into the outer cover 20. At least a pair of lifting spiral grooves 12a are formed in the connecting portion 12 to guide the up and down movement of the lifting mechanism 30. In other words, the lifting protrusion 32 of the lifting mechanism 30 is inserted into the lifting spiral groove 12a, and the lifting protrusion 32 rotates within a predetermined range through the outer cover 20 and moves along the lifting spiral groove 12a, thereby gradually lifting and lowering the lifting mechanism 30. Preferably, the lifting spiral groove 12a extends along the outer wall of the connecting portion 12 in a smooth curve with a predetermined inclination angle, and one end is open for assembling the lifting protrusion 32.

[0054] In addition, the inclination angle of the lifting spiral groove 12a can be changed, so that the rotation range, lifting speed and usability of the lifting mechanism 30 can be adjusted. For example, when the inclination angle of the lifting spiral groove 12a is formed to be relatively steep, the rotation range of the outer cover 20 for completely lifting and lowering the lifting mechanism 30 is shortened, so the lifting mechanism 30 can be lifted and lowered faster. On the contrary, when the inclination angle of the lifting spiral groove 12a is relatively gentle, the rotation range of the outer cover 20 for completely lifting and lowering the lifting mechanism 30 becomes longer, so the lifting mechanism 30 can be lifted and lowered slowly and naturally. Therefore, by comprehensively considering the rotation range, lifting speed, usability, etc. of the lifting mechanism 30, the lifting spiral groove 12a can be formed on the outer wall of the connecting portion 12 with an appropriate inclination angle.

[0055] The outer cover 20 is rotatably connected to one side of the container body 10 and is rotated by a user to rotate the lifting mechanism 30 provided therein.

[0056] As Figure 2 shown, the outer cover 20 has a cylindrical shape with both sides open, and preferably has the same diameter as the container body 10 for the continuity of the design. The outer cover 20 has an opening side into which the connecting portion 12 of the container body 10 is inserted and which houses the lifting mechanism 30, the inner cover 60 and the operation button 70, and another opening side through which the operation button 70 is pulled out or pulled in.

[0057] Lifting straight grooves 22 are formed on the inner circumference of the outer cover 20, and the lifting protrusion 32 passing through the lifting spiral groove 12a is inserted into the lifting straight grooves 22 to rotate the lifting mechanism 30 and at the same time guide the vertical movement of the lifting protrusion 32. Preferably, a pair of lifting straight grooves 22 are formed at opposite positions corresponding to the lifting spiral groove 12a and the lifting protrusion 32, and extend in a predetermined range in the longitudinal direction of the outer cover 20.

[0058] In addition, an insertion space 24 into which a protrusion 76 formed in the operation button 70 is inserted is formed inside the upper part of the outer cover 20, and a pressing prevention step 26 is formed below the insertion space 24 to prevent the operation button 70 from being pressed and operated from inside the outer cover 20.

[0059] The lifting mechanism 30 is connected to the inside of the connecting part 12 of the container body 10 and lifts and lowers inside the container body 10 and the outer cover 20 while rotating together with the outer cover 20.

[0060] At least a pair of lifting protrusions 32 may protrude outward from the outer circumference of the lifting mechanism 30. The lifting protrusions 32 are inserted into the lifting straight groove 22 of the outer cover 20 while passing through the lifting spiral groove 12a of the container body 10, and move along the lifting spiral groove 12a and the lifting straight groove 22 when the outer cover 20 rotates. In other words, the lifting protrusions 32 of the lifting mechanism 30 rotate together with the outer cover 20 through the lifting straight groove 22 of the outer cover 20 and lift and lower inside the container body 10 through the lifting spiral groove 12a of the container body 10, so that the inner cover 60, the content container 40, the discharge mechanism 50 connected to the inner cover 60, and the operation button 70 move up and down simultaneously. Preferably, the lifting protrusions 32 are formed in a pair like the lifting straight groove 22 and are arranged on opposite sides of each other.

[0061] As Figure 2 shown in the partial enlarged view of, the fastening protrusion 34 detachably connected to the inner cover 60 protrudes from the inner circumference of the lifting mechanism 30, and the fastening protrusion 34 may extend along the inner circumference of the lifting mechanism 30 for a predetermined section. In addition, elastic slits 34a for providing elasticity to the fastening protrusion 34 may be formed on both sides of the fastening protrusion 34. The elastic slits 34a may vertically extend for a predetermined section at both ends of the fastening protrusion 34, and when the lifting mechanism 30 and the inner cover 60 are attached and detached, the fastening protrusion 34 bends outward and elastically returns to its original position, and thus, the lifting mechanism 30 and the inner cover 60 can be easily connected or separated.

[0062] In addition, a refill guide groove 36 may be formed on the inner circumference of the lifting mechanism 30. The refill guide groove 36 may guide the separation or insertion direction of the following components so that the refill operation of the inner cover 60 and the content container 40, the discharge mechanism 50 connected to the inner cover 60, and the operation button 70 proceed smoothly. The refill guide groove 36 is formed as a straight line in a predetermined section on the inner circumference of the lifting mechanism 30 along the direction in which the content container 40 is inserted or separated, and preferably, one end of the refill guide groove 36 (i.e., the end in the direction in which the inner cover 60 is separated) may be open, while the other end (i.e., the end in the direction in which the inner cover 60 is inserted) may be closed.

[0063] The guiding inclined surfaces 36a can be formed on two side walls of the opening portion of the refill guiding groove 36 to guide the correct insertion of the refill guiding protrusion 66 formed on the inner lid 60. Preferably, the guiding inclined surfaces 36a are inclined in the outward direction of the refill guiding groove 36 at a predetermined angle. In other words, the guiding inclined surfaces 36a can widen the entrance width of the refill guiding groove 36 to guide the insertion position of the refill guiding protrusion 36, so that the refill guiding protrusion 66 can be more easily inserted into the refill guiding groove 36.

[0064] In addition, the friction protrusions 38 can protrude outward from the upper outer periphery of the lifting mechanism 30, and the friction protrusions 38 can be in close contact with the inner wall of the connecting portion 12 of the container body 10, so as to generate friction between the container body 10 and the lifting mechanism 30 when the lifting mechanism 30 rotates through the outer lid 20. Therefore, it can be expected that the rotational feeling is improved during the rotation operation of the outer lid 20.

[0065] The content container 40 is inserted and stored as a storage member for storing liquid or gel content therein in the internal space of the container body 10.

[0066] The inlet portion 42 can be formed on one side of the content container 40, through which the content can be filled, and a part of the discharge mechanism 50 to be described later can be inserted therein. Preferably, threads are formed on the outer periphery of the inlet portion 42 so as to be threadedly connected to the threads formed on the lower inner periphery of the inner lid 60. In the cosmetic case according to an embodiment of the present invention, the content container 40 and the inner lid 60 are shown to be threadedly connected to each other. However, the present invention is not limited thereto, and can be implemented in various connection schemes within the range of stably and fixedly connecting the content container 40 and the inner lid 60, such as the connection between protrusions and grooves, or forced fit connection or engagement.

[0067] The discharge mechanism 50 is installed at the inlet portion 42 of the content container 40 or at a position adjacent to the inlet portion 42 to discharge the content stored in the content container 40. In other words, while being installed inside the inner lid 60, one side of the discharge mechanism 50 is inserted into the inlet portion 42 of the content container 40 and the other side is connected to the operation button 70. Preferably, the discharge mechanism 50 includes a discharge metering pump, which is a pump for discharging a fixed amount of content to the outside through a pumping operation.

[0068] As Figure 3As shown, the discharging mechanism 50 may include: a housing 51 that is inserted into the inlet portion 42 of the content container 40 and has a content suction port 51a formed at its lower portion; a straw 52 that is connected to the content suction port 51a and inserted into the content container 40; a suction valve plate 53 that is used to open and close the content suction port 51a of the housing 51; a sealing cap 54 that surrounds and is connected to the upper portion of the housing 51; a rod portion 55 that reciprocates along the pumping operation direction while passing through the sealing cap 54; a resilient spring 56 that resiliently supports the rod portion 55; an operating discharge pipe 57 that is connected to the rod portion 55 and reciprocates together with it; and an operating discharge ring 58 that is assembled outside the operating discharge pipe 57 and is in close contact with the inner circumference of the housing 51.

[0069] In addition, a sealing ring 59 may be provided between the housing 51 of the discharging mechanism 50 and the inlet portion 42 of the content container 40 to maintain the airtightness inside the content container 40. The sealing ring 59 is formed of an elastic material for further improving the sealing force of the content container 40, and may preferably be formed of at least one material among polyurethane rubber, natural rubber, elastomer, nitrile rubber (NBR), and silicone resin, or formed of elastic polypropylene, polyethylene, or acrylonitrile butadiene styrene (ABS), and particularly, it may be most desirable to be formed of a thermoplastic elastomer (TPE) which is a material between rubber and plastic and has softness and excellent durability.

[0070] The inner lid 60 is connected to the inlet portion 42 of the content container 40 and rises or falls together with the lifting mechanism 30 while being fastened to the lifting mechanism 30, and the discharging mechanism 50 may be installed while passing through the center of the inner lid 60. The lower inner wall 61 may extend downward from the inner lid 60, the lower outer wall 63 may extend downward while being spaced apart from the outside of the lower inner wall 61 by a predetermined interval, and a thread may be formed on the inner circumference of the lower outer wall 63 to be threadedly connected to the thread formed in the inlet portion 42 of the content container 40.

[0071] As Figure 2 shown, a fastening groove 64 that is detachably connected to the lifting mechanism 30 is formed on the outer circumference of the inner lid 60, and a fastening protrusion 34 of the lifting mechanism 30 may be connected to the fastening groove 64. The fastening groove 64 may extend completely along the outer circumference of the inner lid 60.

[0072] In addition, a refill guiding projection 66 is formed on the outer periphery of the inner lid 60, and the refill guiding projection 66 can be inserted into the refill guiding groove 36 of the lifting mechanism 30. The refill guiding projection 66 can be formed in a straight line in a predetermined section on the outer periphery of the inner lid 60 along the direction in which the content container 40 is inserted or separated, and can be disposed below the fastening groove 64 to allow the refill guiding projection 66 to be inserted into the refill guiding groove 36, and then the fastening groove 66 and the fastening projection 34 are fastened in sequence.

[0073] In addition, as Figure 3 shown, the locking claw 67 can protrude outward from the upper part of the fastening groove 64 of the inner lid 60, so that the separation of the inner lid 60 into the container body 10 can be prevented. At least one guiding straight hole 68 can be formed in the upper part of the inner lid 60, so that the linear reciprocating movement of the operation button 70 can be guided. Preferably, the guiding straight hole 68 extends in a predetermined section along the movement direction of the operation button 70.

[0074] The operation button 70 is connected to the discharging mechanism 50 to discharge the content stored in the content container 40 to the outside while performing a vertical reciprocating movement through the pressing operation of the user.

[0075] A discharge channel 72 can be formed in the center of the operation button 70 to connect to the discharging mechanism 50.

[0076] A nozzle connection hole 74 can be formed on one side of the discharge channel 72, and a nozzle 80 having a discharge port 82 can be connected to the nozzle connection hole 74. Preferably, the nozzle 80 is completely inserted into the nozzle connection hole 74.

[0077] In addition, a protrusion 76 can protrude outward from the outer periphery of the operation button 70. When the operation button 70 is pulled into the outer lid 20, the protrusion 76 is inserted into the insertion space 24 of the outer lid 20 and is located at the upper end of the anti-pressing step 26 to limit the pressing of the operation button 70. Therefore, when storing or carrying the cosmetic case, the operation button 70 inserted into the outer lid 20 can be prevented from being pressed by external force and misoperated.

[0078] In addition, at least one guiding straight protrusion 78 can protrude from the inner periphery of the operation button 70 to be inserted into the guiding straight hole 68 of the inner lid 60. Preferably, similar to the guiding straight hole 68 of the inner lid 60, the guiding straight protrusion 78 can extend in a predetermined section along the movement direction of the operation button 70.

[0079] As described above, in the cosmetic case according to an embodiment of the present invention, the content container, the discharge mechanism, the inner lid, and the operation button are lifted and lowered within a predetermined range by rotating the outer lid, and a part thereof is pulled out or pulled into the container body, thereby facilitating the use convenience. When carrying or storing, it is possible to prevent the operation button from being operated by an external force regardless of the user's intention. When the content stored in the content container is exhausted, it is possible to prevent the entire cosmetic case from being discarded, and it is possible to replace only the content container combined with the discharge mechanism, the inner lid, and the operation button from the container body. Therefore, the economic burden on the user can be reduced, and resource waste and environmental pollution can be reduced. In addition, in the cosmetic case according to an embodiment of the present invention, the content container, the discharge mechanism, the inner lid, and the operation button that are lifted and lowered together with the container body can be easily separated after being pulled out from the container body, and can be easily fixed after being pushed into the inner space of the container body, so that the refilling operation can be carried out more smoothly.

[0080] Figures 4 to 9 FIG. is a view for explaining the use and refilling of a cosmetic case having a refilling structure according to an embodiment of the present invention. The use and refilling method of a cosmetic case having a refilling structure according to an embodiment of the present invention will be described with reference to the above drawings.

[0081] Figure 4 FIG. is a perspective view showing a state in which an operation button is pulled into an outer lid according to an embodiment of the present invention. Figure 5 FIG. is a perspective view showing a state in which an operation button is pulled out from an outer lid according to an embodiment of the present invention. Figure 6 FIG. is a cross-sectional view showing a state in which an operation button is pressed according to an embodiment of the present invention. Figure 7 FIG. is a cross-sectional view showing a state in which the pressing of an operation button is released according to an embodiment of the present invention. Figure 8 FIG. is a cross-sectional view showing a state in which a content container, a discharge mechanism, and an operation button are separated from a container body and an outer lid according to an embodiment of the present invention. Figure 9 FIG. is a cross-sectional view showing a state in which a content container, a discharge mechanism, and an operation button are inserted into an inner space of a container body and an outer lid according to an embodiment of the present invention.

[0082] To use the cosmetic case having a refilling structure according to the present invention, the container body 10 is held and the outer lid 20 is rotated in one direction.

[0083] As Figure 5As shown, when the outer lid 20 rotates relative to the container body 10, the lifting projection 32 of the lifting mechanism 30 inserted into the lifting straight groove 22 of the outer lid 20 rotates together with the outer lid 20, and at the same time, the lifting projection 32 moves upward along the lifting spiral groove 12a of the container body 10. As the inner lid 60 is fastened to the lifting mechanism 30 and the content container 40, the discharge mechanism 50 and the operation button 70 connected to the inner lid 60 gradually rise, and the operation button 70 is pulled outwards from the outer lid 20. The lifting projection 32 of the lifting mechanism 30 moves linearly within the lifting straight groove 22 of the outer lid 20.

[0084] After that, as Figure 6 shown, when the discharge mechanism 50 connected to the operation button 70 is pressurized by pressing the operation button 70 exposed to the outside, the rod portion 55 of the discharge mechanism 50 and the operation discharge pipe 57 connected to the lower portion of the rod portion 55 move downward together. Since the operation discharge ring 58 is in close contact with the inner surface of the housing 51, only the operation discharge pipe 57 moves downward, so a gap is generated between the operation discharge pipe 57 and the operation discharge ring 58, thereby creating a passage for the content.

[0085] After that, when the operation button 70 is continuously pressed, the lower end of the rod portion 55 that moves downward through the operation button 70 presses the operation discharge ring 58, causing the operation discharge ring 58 to move downward together with the operation discharge pipe 57, thereby reducing the volume inside the housing 51. Therefore, the suction valve plate 53 closes the content suction port 51a due to the discharge pressure in the housing 51, and the content accommodated in the housing 51 comes out simultaneously between the operation discharge pipe 57 and the operation discharge ring 58, passes through the inlet passage formed in the center of the operation discharge pipe 57, and is discharged to the discharge port 82 of the nozzle 80 via the discharge passage 72 of the operation button 70.

[0086] After that, as Figure 7 shown, when the pressure on the operation button 70 is released, the elastic spring 56 that elastically supports the rod portion 55 of the discharge mechanism 50 returns to its original shape, causing the rod portion 55 to move upward, and the operation discharge pipe 57 connected to the lower side of the rod portion 55 also moves upward. The lower portion of the operation discharge pipe 57 pulls the operation discharge ring 58 upward and the gap between the operation discharge pipe 57 and the operation discharge ring 58 is blocked, causing the operation discharge pipe 57 and the operation discharge ring 58 to move upward together, so the volume inside the housing 51 increases, thereby generating a vacuum pressure.

[0087] After that, the suction valve plate 53 rises due to the vacuum pressure generated inside the housing 51, so the content suction port 51a formed on the bottom surface of the housing 51 opens, allowing the content accommodated in the content container 40 to be introduced into the housing 51 through the straw 52.

[0088] After makeup is completed, the operation button 70 is inserted into the outer cover 20 for storage or carrying. When the outer cover 20 is rotated in the reverse direction, the lifting projection 32 of the lifting mechanism 30 inserted into the linear lifting groove 22 of the outer cover 20 rotates together with the outer cover 20, and at the same time, the lifting projection 32 moves downward along the lifting spiral groove 12a of the container body 10. As the inner cover 60 is fastened to the lifting mechanism 30 and the content container 40, the discharge mechanism 50 and the operation button 70 connected to the inner cover 60 gradually descend, and the operation button 70 is pulled into the outer cover 20, as Figure 4 shown. The lifting projection 32 of the lifting mechanism 30 moves linearly within the linear lifting groove 22 of the outer cover 20.

[0089] In addition, when all the contents contained in the content container 40 are used up, the content container 40 can be replaced and used. As Figure 8 shown, when the outer cover 20 is rotated relative to the container body 10 to pull the operation button 70 out of the outer cover 20 and the operation button 70 is pulled out of the container body 10, the inner cover 60 is pulled together with the operation button 70, and the fastening between the fastening projection 34 formed in the lifting mechanism 30 and the fastening groove 64 formed in the inner cover 60 is simultaneously released, so that the lifting mechanism 30 and the inner cover 60 are separated, and continuously, the inner cover 60, the content container 40, the discharge mechanism 50 connected to the inner cover 60, and the operation button 70 come out of the container body 10 and the outer cover 20 together.

[0090] As Figure 9 shown, the discharge mechanism 50, the inner cover 60, and the operation button 70 connected to the new content container 40 are inserted into the container body 10 while being inserted into the opening of the outer cover 20. The refill guide projection 66 of the inner cover 60 is guided to the correct position by the guiding inclined surface 36a of the lifting mechanism 30 and inserted into the refill guide groove 36, so that the refill operation proceeds smoothly.
