Description

Technical Field

[0001] The invention relates to an environmentally friendly container, in particular to an environmentally friendly container made of recyclable materials. Background Art

[0002] Pharmaceuticals can be manufactured in various forms such as liquid, powder, and tablets. The reason why pharmaceuticals are manufactured in various forms is to maximize the convenience and effectiveness of patients taking medical products.

[0003] In order to maintain the best effect of medicines, their storage containers are very important. The storage containers vary according to the type of medicines, and are usually made of polypropylene (PP) or polyethylene terephthalate (PET).

[0004] However, polypropylene (PP) and polyethylene terephthalate (PET) materials have low hygroscopicity and therefore cannot remove moisture from pharmaceuticals. Liquids do not present a major problem even when made from these materials, but powders and tablets generally require a separate dryer to be placed inside a storage container in order to maintain the effects of pharmaceuticals that are extremely susceptible to moisture.

[0005] In this regard, the prior document (registered patent) No. 10-1726981 discloses a "sheet medicine protection device that simultaneously performs a buffering function and a dehumidifying function by being inserted into a sheet medicine storage container, and a sheet medicine storage container using the sheet medicine protection device". In the sheet medicine storage container, a desiccant that is separately provided and inserted into the container can absorb moisture from the medicine inside the container.

[0006] However, the above-mentioned tablet medicine storage container needs to be equipped with a desiccant separately, and a complex structure is required to form a separate space for storing the desiccant. In addition, there is a problem that the desiccant may leak and mix with the medicine or cause pollution to the surroundings, and the components must be disassembled in order to recycle it.

[0007] In addition, carbon neutrality, which reduces actual carbon emissions to "0" level in order to minimize greenhouse gases, has become an important paradigm in the era of the Fourth Industrial Revolution.

[0008] Therefore, from an individual perspective, consumers need to actively participate in the separation and recycling of materials to achieve effective recycling, and from a corporate perspective, manufacturers need to produce products that use environmentally friendly materials and adopt a design structure that allows for easy separation and recycling of product materials. In other words, pharmaceutical containers need to be designed in a form that facilitates separation and recycling.

[0104] Next, the embodiments described in this specification will be described with reference to the ideal drawings of the present invention. The morphology of the illustrated drawings may be deformed according to manufacturing technology and / or tolerances. Therefore, the embodiments of the present invention are not limited to the specific morphology shown in the drawings, but include changes in morphology caused by manufacturing processes.

[0105] In the process of describing multiple embodiments, for the convenience of description, the same names and the same reference numbers are assigned to the components that perform the same functions even in different embodiments. Furthermore, for the convenience of description, the components and actions that have been described in other embodiments will be omitted.

[0106] In addition, "at least one of A, B and C" means that it is composed of one, two or three of A, B and C, and "at least one D" means that there is more than one D. In addition, "the upper end of E" means the end located at the upper part of E.

[0107] First, the basic structure of the environmentally friendly container 1 according to the embodiment of the present invention will be described.

[0108] Figure 1 It is a schematic diagram illustrating an environmentally friendly container 1 according to an embodiment of the present invention. Figure 2 It is a schematic diagram illustrating the separation state of the environmentally friendly container 1 according to an embodiment of the present invention.

[0109] See also Figure 1 as well as Figure 2 According to an embodiment of the present invention, an environmentally friendly container 1 can store medicines and may include: an external shell 100, which is formed with an opening 100a; a cover 200; a lid for opening and closing the opening 100a of the external shell 100; and an internal shell 300, which is inserted into the interior of the external shell 100 in a detachable manner through the opening 100a.

[0110] In addition, the outer shell 100 according to the embodiment of the present invention may further include a first receiving space 101 for receiving the inner shell 300. The inner shell 300 may include a second receiving space 301 for receiving the medicine. The inner shell 300 may be separated from the outer shell 100 by translation.

[0111] The outer shell 100 may include an opening 100a. The outer shell 100 may be held by a user by being exposed to the outside of the environmentally friendly container 1. The outer shell 100 may include an outer surface exposed to the outside and an inner surface contacting or facing the inner shell 300.

[0112] The outer shell 100 can be inserted into or separated from the inner shell 300 through the opening 100a. The outer shell 100 can be formed in a shape such as a cylinder and a prism. The outer shell 100 can be formed in a structure corresponding to the inner shell 300 so that the inner shell 300 can be easily removed. The corresponding structure will be described in the subsequent content.

[0113] The cover 200 can open and close the opening 100a of the external housing 100. The cover 200 can be connected to the external housing 100 through the connection part 240. One side of the connection part 240 can be extended from the cover 200, and the other side can be extended from the external housing 100. However, it is not necessarily limited to the structure in which the cover 200 and the external housing 100 are connected through the connection part 240, and a structure that is independent and separable from each other can also be adopted.

[0114] In the case of adopting a structure in which the cover 200 is separated from the external case 100 , threads may be formed inside the cover 200 and threads may be formed on an upper outer surface of the external case 100 so as to be coupled to each other.

[0115] In contrast, in the case of a structure in which the cover 200 and the external housing 100 are connected via the connection portion 240, the external housing 100 can be forcibly embedded with the cover 200 by forming an embedding edge 160 formed along the upper end or the upper outer surface. The embedding edge 160 can maintain the cover 200 in a closed state. However, the above-mentioned forced embedding method can also be applied to a structure in which the cover 200 and the external housing 100 are separated.

[0116] The inner housing 300 can be inserted into or separated from the outer housing 100. The inner housing 300 can be inserted into or separated from the opening 100a of the outer housing 100. The inner housing 300 can include an outer surface that contacts or faces the outer housing 100 and an inner surface that contacts the medicine.

[0117] In addition, the inner shell 300 may further include a lower surface, and the lower surface may be formed to be recessed upward or to be formed to be flat. In addition, the inner shell 300 may include an inner opening 300a at the upper portion, and the medicine may be stored through the inner opening 300a.

[0118] When the inner housing 300 is completely inserted into the outer housing 100, the upper end of the inner housing 300 may be located below the upper end of the outer housing 100. That is, the inner opening 300a of the inner housing 300 may be located below the opening 100a of the outer opening 100, and the inner opening 300a may be located in the first receiving space 101.

[0119] The inner housing 300 may be formed in the form of a cylinder or a prism, etc. The inner housing 300 may be formed in a structure corresponding to the outer housing 100 so as to be easily removed from the outer housing 100. The corresponding structure will be described in the following content.

[0120] The outer housing 100 may include a first receiving space 101, and the inner housing 300 may include a second receiving space 301. The first receiving space 101 may refer to a space for receiving the inner housing 300, and the second receiving space 301 may refer to a space for receiving medicines.

[0121] The inner housing 300 can be separated from the outer housing 100 by translational motion or sliding motion. Translational motion or sliding motion is different from rotational motion, and can be separated from the outer housing 100 without rotating the inner housing 300. In order to facilitate the separation of the inner housing 300, it is necessary to simplify the structure of the inner surface of the outer housing 100 during the separation process of the inner housing 300.

[0122] That is, it is necessary to minimize or eliminate all blocking elements located on the opening area 100b where the opening 100a of the outer housing 100 is located. The opening area 100b may refer to the first receiving space 101 which is higher than the upper end of the inner housing 300 when the inner housing 300 is fully inserted into the outer housing 100.

[0123] The opening area 100b may refer to Figure 4a , represents the space from the dotted line of the internal shell 300 to the upper end of the external shell 100. The upper end of the internal shell 300 may refer to a line formed along the uppermost end of the internal shell 300 including the grip portion 310. In addition, the upper end of the internal shell 300 may refer to a line formed along the uppermost end of the internal shell 300 excluding the grip portion 310. In other words, the opening area 100b may refer to an area where the internal shell 100 and the external shell 300 do not overlap when the internal shell 100 and the external shell 300 are combined.

[0124] The opening area 100b of the outer housing 100 may be formed with the same cross-sectional width. In addition, the opening area 100b of the outer housing 100 may be formed with the same cross-sectional shape. In addition, the opening area 100b of the outer housing 100 may be formed in a manner that the cross-sectional width gradually increases toward the upper portion.

[0125] The opening area 100b may be formed in a structure such that when the inner shell 100 is separated from the outer shell 300 by translational motion or sliding motion, the upper end of the inner shell 100 will not be blocked by the blocking elements inside the outer shell 300. For example, the inner surface of the outer shell 100 at the position of the opening area 100b may be configured in a manner such that there is no curved area, embedded area, protruding area, arched area, and bottle mouth area facing the first receiving space 101.

[0126] The shape of the external shell 300 can be constructed in a way that there is no bending area, embedded area and protruding area toward the first receiving space 101, but there can be a protrusion 400 as described later that does not hinder the translational movement or sliding movement of the internal shell 300.

[0127] The inner housing 300 may be fixed to the outer housing 100. The term "fixed" refers to a state in which the inner housing 300 is completely inserted into the outer housing 100, and does not refer to a state in which the inner housing 300 cannot be separated.

[0128] At this time, the inner housing 300 can be fixed only by the friction between the outer surface of the inner housing 300 and the inner surface of the outer housing 100. In addition, when the inner housing 300 includes the protrusion 400, it can be fixed only by the friction between the protrusion 400 of the inner housing 300 and the inner surface of the outer housing 100. In addition, when the outer housing 300 includes the protrusion 400, it can be fixed only by the friction between the outer surface of the inner housing 300 and the protrusion 400.

[0129] The inner case 300 is fixed only by the friction force between the inner case 300 and the outer case 100 , and all components fixing the inner case 300 to the outer case 100 are removed, so that the inner case 300 can be easily separated from the outer case 100 .

[0130] That is, when the friction force between the user's hand and the inner housing 300 is greater than the friction force between the inner housing 300 and the outer housing 100 , the inner housing 300 may be separated from the outer housing 100 .

[0131] Thereby, the inner case 300 can be separated from the outer case 100 without rotational motion. Furthermore, the inner case 300 can be separated from the outer case 100 only by translational motion or sliding motion without damaging at least one of the inner case 300 and the outer case 100.

[0132] Furthermore, in order to smoothly separate the inner housing 300 , the inner surface of the outer housing 100 and the outer surface of the inner housing 300 may be configured in a corresponding structure.

[0133] As an example of a corresponding structure, it may refer to a structure in which, when an edge is formed on the internal shell 300 or the external shell 100, a groove is formed on the external shell 100 or the internal shell 300 for the edge to be embedded, so that the internal shell 300 can be separated from the external shell 100 only by translational movement or sliding movement; it may refer to a structure in which an edge is formed in one of the internal shell 300 and the external shell 100; it may also refer to a threaded structure of the internal shell 300 and the external shell 100 described later.

[0134] With the above-described structure, the user can easily separate the inner case 300 from the outer case 100. By separating the recycling components without damaging the inner case 300 or the outer case 100, the recycling of materials can be promoted.

[0135] Next, the environmentally friendly materials of the outer case 100 and the inner case 300 will be described.

[0136] The outer shell 100 may include polypropylene (PP) and / or polyethylene terephthalate (PET) materials. In addition, the outer shell 100 may be made of post-consumer recycled (PCR) materials. Polypropylene (PP) and polyethylene terephthalate (PET) materials are environmentally friendly materials that are light in weight, excellent in strength, and harmless to the human body and the environment.

[0137] The inner shell 300 may include a zeolite material. The inner shell 300 may be formed using a polypropylene matrix (PP matrix) including zeolite, but is not limited thereto.

[0138] At this time, the zeolite can be obtained naturally or synthetically, and can be composed of at least one of zeolite A, zeolite X and zeolite Y classified according to the ratio of silicon to aluminum, and can also be composed of at least one of faujasite (FAU) zeolite, P1 zeolite and sodalite classified according to morphology.

[0139] The outer shell 100 may be made of a material that is strong and can prevent water from flowing in, such as polypropylene (PP) and / or polyethylene terephthalate (PET), and the inner shell 300 may be made of a zeolite material that is highly hygroscopic. In this way, the environmentally friendly container 1 can simultaneously achieve the effects of blocking external water with the help of the outer shell 100 and absorbing internal water with the help of the inner shell 300.

[0140] In particular, by using a material with strong hygroscopicity to form the inner shell 300, moisture in the second receiving space 301 can be absorbed and the moisture can be prevented from being absorbed by the medicine.

[0141] When the pharmaceutical container is composed of only an outer shell (single shell), a desiccant must be used because hygroscopicity cannot be ensured. When a desiccant is used, a separate space must be formed, which complicates the structure and makes separation and recovery difficult.

[0142] In contrast, the outer shell 100 and the inner shell 300 of the environmentally friendly container 1 according to the embodiment of the present invention are constructed separately and can be easily separated, thereby ensuring both the hygroscopicity and the convenience of separation and recycling.

[0143] That is, the manufacturer can use environmentally friendly and recyclable materials to produce an easily separable environmentally friendly container 1, and the user can achieve the effect of reducing waste and recycling materials by easily separating and recycling it.

[0144] Next, the structure of the lower surface of the external housing 100 will be described.

[0145] Figure 3a The diagram is a schematic diagram illustrating the pressurizing portion 120 and the pressurizing gap 110 before pressurization according to an embodiment of the present invention. Figure 3b The diagram is a schematic diagram illustrating the pressurized portion 120 and the pressurized gap 110 after pressurization according to an embodiment of the present invention. Figure 3c The diagram is a schematic diagram illustrating the pressurizing portion 120 and the pressurizing gap 110 before pressurization according to an embodiment of the present invention. Figure 3d The diagram is a schematic diagram illustrating the pressurizing portion 120 and the pressurizing gap 110 after pressurization according to an embodiment of the present invention.

[0146] See also Figure 3a as well as Figure 3d The outer housing 100 may include a pressurizing portion 120 formed on a lower surface of the outer housing 100 in order to push the inner housing 300 upward outside the outer housing 100 .

[0147] In addition, the outer shell 100 may further include a pressurizing gap 110 formed along the periphery of the pressurizing portion 120 for deforming the pressurizing portion 120 .

[0148] The outer case 100 may include an opening portion 100a at an upper portion, and may further include a side surface and a lower surface. The opening portion 100a may be located at an upper portion of the side surface, and the lower surface may be located at a lower portion thereof.

[0149] The outer housing 100 may include a pressurizing slit 110 and / or a pressurizing portion 120 at the lower surface. The pressurizing portion 120 may be located at a central portion of the lower surface, and the pressurizing slit 110 may be formed along a periphery of the pressurizing portion 120.

[0150] The pressurizing slit 110 may be formed so as to penetrate the lower surface of the external housing 100 (hole structure), or may be formed so as to be embedded from the lower surface to the upper portion of the external housing 100 (slit structure).

[0151] Specifically, the pressurizing slit may be formed in a curved hole structure or a groove structure in the peripheral direction along the periphery of the pressurizing portion 120. In addition, one or more pressurizing slits 110 may be formed, and a plurality of pressurizing slits 110 may be formed spaced apart from each other.

[0152] The pressurized slit 110 can be formed in a way that air inside and outside the outer shell 100 can circulate, which is called a hole structure. Different from this, the pressurized slit 110 can also be formed in a way that air inside and outside the outer shell 100 cannot circulate, which is called a slit structure.

[0153] In addition, the pressurizing slit 110 may be formed alone without forming the pressurizing portion 120. In the above case, a plurality of pressurizing slits 110 may be formed, and the shape thereof is not limited. That is, the pressurizing slit 110 may be formed in various shapes such as a straight line, a circle, an ellipse, and a polygon, in addition to the curved shape as described above.

[0154] When the pressurized gap 110 adopts a hole structure, the pressurized gap can allow air to pass through so that the inner housing 300 can move freely on the outer housing 100. When the inner housing 300 is inserted into the outer housing 100, the air in the first receiving space 101 can flow out to the outside through the pressurized gap 110 when the inner housing 300 moves.

[0155] On the contrary, when the inner housing 300 is separated from the outer housing 100 , external air may flow into the first receiving space 101 through the pressurization gap 110 when the inner housing 300 moves.

[0156] When the pressurized gap 110 adopts a gap structure, air circulation can be prevented because the pressurized gap 110 does not penetrate the external housing 100. In this way, the external housing 100 can play a waterproof function.

[0157] At this time, the thickness of the region where the pressurizing gap 110 exists in the external housing 100 may be smaller than the thickness of the region where the pressurizing gap 110 does not exist.

[0158] The pressurizing gap 110 can automatically widen when the pressurizing portion 120 is pressurized and cause the pressurizing portion to move upward ( Figure 3a as well as Figure 3c ), on the contrary, the pressurizing gap 110 may automatically narrow when the pressurizing state of the pressurizing portion 120 is released and cause the pressurizing portion 120 to move downward ( Figure 3b as well as Figure 3d ).

[0159] The pressurizing portion 120 may be formed to be concave upward, or may be formed to be flat.

[0160] The pressurizing portion 120 can move toward the first receiving space 101 and enter a pressurizing state when an external force is applied, and can move toward the outside again and enter a basic state when the external force disappears.

[0161] The environmentally friendly container 1 can easily separate the inner shell 300 from the outer shell 100 by using the pressurizing gap 110 and the pressurizing portion 120 .

[0162] Next, the structures of the external case 100 and the cover 200 will be described.

[0163] Figure 4a It is a schematic diagram illustrating the state before the hook portion 230 and the loop portion 130 are combined according to an embodiment of the present invention. Figure 4b It is a schematic diagram illustrating the combined state of the hook portion 230 and the loop portion 130 according to an embodiment of the present invention. Figure 4c It is a schematic diagram illustrating the combined state of the hook portion 230 and the loop portion 130 according to an embodiment of the present invention.

[0164] See also Figure 4a According to an embodiment of the present invention, the outer shell 100 may include: a cover edge 150 , which is formed to protrude along the periphery of the outer shell 100 at the upper part of the outer shell 100 .

[0165] See also Figure 4a as well as Figure 4b According to an embodiment of the present invention, the outer shell 100 may further include: a ring portion 130, which is located at the upper portion of the outer shell 100 and has a through area 130a. The cover 200 may include: a hook portion 230, which is extended toward the lower portion of the cover 200. The hook portion 230 may pass through the through area 130a and be combined with the ring portion 130.

[0166] In addition, the cover 200 according to the embodiment of the present invention may further include: an embedding portion 210 for introducing the upper end of the outer shell 100 into the interior of the cover 200; and a handle portion 220 formed from the embedding portion 210 toward the outside of the cover 200. The hook portion 230 may be formed by extending from the lower surface of the handle portion 220.

[0167] The outer shell 100 may include a cover edge 150 at the upper portion. The cover edge 150 may be located at a distance within the height of the cover 200 from the upper end portion. The cover edge 150 may be formed along the periphery of the outer shell 100. The cover edge 150 may be formed on the entire periphery of the outer shell 100, and a portion thereof may be formed in the form of the ring portion 130 described later.

[0168] The cover edge 150 may provide a space for the cover 200 to be placed when the cover 200 closes the opening 100a of the external housing 100. Specifically, the cover edge 150 may contact the lower end of the cover 200.

[0169] That is, the cover edge 150 can restrict the insertion of the insertion portion 210 into the outer housing 100. Thus, even when the cover 200 is closed with excessive force, the cover 200 can be prevented from being damaged by the end of the outer housing 100.

[0170] The external case 100 may further include a ring portion 130 . The ring portion 130 may maintain a closed state of the opening portion 100 a of the external case 100 by being combined with the hook portion 230 of the cover 200 .

[0171] See also Figure 4a The ring portion 130 may be located at the upper portion of the outer shell 100 and may be formed by extending from the cover edge 150. However, the ring portion 130 is not necessarily limited to the following. Figure 4a The structure shown can also be formed independently of the cover edge 150.

[0172] A portion of the ring portion 130 may contact the outer surface of the outer shell 100 to form a through region 130a. Specifically, the left and right sides of the ring portion 130 may contact the outer surface of the outer shell 100, and the central portion may be separated from the outer shell 100 to form the through region 130a. The through region 130a refers to a region between the outer surface of the outer shell 100 and the ring portion 130 through which the hook portion 230 can pass.

[0173] The ring 130 can prevent the hook from being exposed to the outside by forming a through area 130a between the ring 130 and the outer surface of the outer shell 100. Thereby, the ring 130 can provide protection for the hook 230 when it is subjected to external impact and the hook 230 is engaged, thereby preventing the cover 200 from being damaged.

[0174] Figure 4a The ring portion 130 shown in the figure is formed by extending from the cover edge 150, and its two sides are in contact with the outer shell 100, so that the center is formed in a state separated from the outer shell 100. In addition, the ring portion 130 can be formed in a "U" shape, but is not necessarily limited to the above-mentioned form.

[0175] The cover 200 may include a hook portion 230 . The hook portion 230 may include a first portion 231 extending downward from the cover 200 and a second portion 232 protruding from the first portion 231 toward the outside of the external case 100 .

[0176] See also Figure 4b When the opening portion 100 a of the external housing 100 is closed, the hook portion 230 may pass through the through region 130 a of the ring portion 130 and be combined with the inner side of the ring portion 130 .

[0177] At this time, an edge may be formed inside the ring portion 130 so that the second portion 232 of the hook portion 230 can be snapped onto the edge of the ring portion 130 and combined with each other. That is, the second portion 232 may protrude toward the outside of the outer housing 100 and be combined with the ring portion 130.

[0178] As described above, by forming the hook portion 230 and the coupling portion of the ring portion 130 inside the ring portion 130 , it is possible to prevent the cover 200 from being damaged by an external force.

[0179] See also Figure 4c , the ring portion 130 may be formed by tilting downward from the cover edge 150. In this case, the ring portion 130 may not be separated from the outer shell 100, but the ring portion 130 may be extended from the cover edge 150 to form a truncated area, namely two clamping areas 130b. The clamping area 130b is equivalent to Figure 4a as well as Figure 4b The structure corresponding to the through area 130a in .

[0180] In the above case, the hook portion 230 may include a first portion 231 formed to extend downward from the cover 200 , and may include a third portion 233 recessed inward from both sides of the first portion 231 .

[0181] When the opening 100a of the outer shell 100 is closed, the hook 230 can pass through the clamping area 130b of the ring 130 and be combined with the ring 130. In the above case, although the clamping area 130b is exposed to the outside, it can be prevented from being damaged by external force by means of the handle 220 described later.

[0182] The hook portion 230 and the loop portion 130 are not limited to Figures 4a to 4cThat is, the hook portion 230 and the ring portion 130 may be configured in a structure that does not function as a clamping element when the inner housing 300 is separated from the outer housing 100, and may preferably be located outside the outer housing 100.

[0183] The cover 200 may include an embedding portion 210. The embedding portion 210 may be formed in a shape protruding upward when viewed from the upper portion of the cover 200, and may be formed in a shape recessed upward when viewed from the lower portion. That is, the embedding portion 210 may refer to a portion into which the upper end of the external housing 100 may enter. The embedding portion 210 of the cover 200 and the embedding edge 160 of the external housing 100 may maintain the closed state of the opening 100a by forcibly embedding each other.

[0184] The cover 200 may include a handle portion 220. The handle portion 220 may be formed by extending from the embedding portion 210 toward the outside of the cover 200. The handle portion 220 may correspond to a portion to which a user applies force when opening the cover 200.

[0185] The cover 200 may be provided with a connection portion 240 connected to the outer shell 100 on one side and a handle portion 220 on the other side. That is, the handle portion 220 may be lifted by a user to open the cover 200 with the connection portion 240 as an axis by means of a lever principle.

[0186] At this time, the hook portion 230 may be extended from the lower surface of the handle portion 220. When the hook portion 230 is located at the handle portion 220, the hook portion 230 and the ring portion 130 may be combined outside the outer shell 100, so the ring portion 130 may also be located on the outer surface of the outer shell 100.

[0187] With the above structure, the inner housing 300 can be separated from the outer housing 100 without being hindered by any snap-fit ​​elements. That is, the hook 230 and the ring 130 can be easily separated from the inner housing 300 by the structure fastened to each other outside the outer housing 100.

[0188] The convex shape of the handle portion 220 can provide protection for the ring portion 130 and the hook portion 230 when subjected to external force, and by means of the lever principle, the cover 200 can be easily opened even with a small force to thereby open the opening portion 100a of the external shell 100.

[0189] That is, the environmentally friendly container 1 according to the embodiment of the present invention can easily separate the inner shell 300 by configuring the ring portion 130 and the hook portion 230 on the outside of the outer shell 100, and the ring portion 130 can prevent the cover 200 from being damaged due to external force by hiding the hook portion 230, and then the opening portion 100a of the outer shell 100 can be easily opened even with a small force with the help of the handle portion 220.

[0190] Next, another embodiment of the coupling structure of the outer case 100 and the cover 200 will be described.

[0191] Figure 4d The diagram is a schematic diagram illustrating the state before the hook portion 230 and the hook groove 221 are combined according to an embodiment of the present invention. Figure 4e It is a schematic diagram illustrating the combined state of the hook portion 230 and the hook groove 221 according to the embodiment of the present invention.

[0192] In the above, the structure in which the cover 200 includes the hook portion 230 and the external housing 100 includes the ring portion 130 and the hook portion 230 is combined with the ring portion 130 is described.

[0193] In addition, see Figure 4d as well as Figure 4e The external shell 100 may include an embedded edge 160 formed along the upper external surface of the external shell 100 and a hook portion 230 connected to the external shell 100, and the cover 200 may include an embedded portion 210 for introducing the embedded edge 160 into the interior of the cover 200 and a hook groove 221 for the hook portion 230 to pass through and engage.

[0194] The outer case 100 may include a hook portion 230, and the cover 100 may include a hook groove 221. The hook portion 230 may be combined with the hook groove 221.

[0195] The outer shell 100 may include a hook portion 230, a support portion 170, and a hook connection portion 230a. As described above, the hook portion 230 may include a first portion 231 and a second portion 232. However, unlike the above, the hook portion 230 may be extended from the support portion 170 and formed upward, and may be directly or indirectly connected to the outer shell 100.

[0196] The support portion 170 may have the same structure as the hook portion 130, but unlike the hook portion 130, the through region 130a may not be formed. In this case, the support portion 170 may separate the hook portion 230 from the external housing 100. However, the shape of the support portion 170 is not particularly limited, and any shape that can separate the hook portion 230 from the external housing 100 may be adopted.

[0197] The support portion 170 may include a first support portion 170a and a second support portion 170b. The first support portion 170a may be located on the outer surface of the external housing 100 to provide a distance between the hook portion 230 and the external housing 100. The second support portion 170b may be connected to the first support portion 170a and may be connected to the hook portion 230.

[0198] The support portion 170 may space the hook portion 230 from the external housing 100 , thereby providing a space for the edge of the embedding portion 210 to be located when the cover 200 closes the external housing 100 .

[0199] At this time, the embedding portion 210 may include a 1-1 sealing portion 211, a 1-2 sealing portion 212, and a 1-3 sealing portion at the edge. That is, the 1-1 sealing portion 211 to the 103 sealing portion 213 may be located between the hook portion 230 and the outer surface of the outer housing 100.

[0200] The hook connection portion 230a may be located between the support portion 170 and the hook portion 230, with one end connected to the support portion 170 and the other end connected to the hook portion 230. The hook connection portion 230a may be formed with a width smaller than the hook portion 230. The width refers to the length in a direction toward the outside or inside of the external housing 100.

[0201] The hook connection part 230a can make the hook part 230 easily move toward the inside and outside of the outer shell 100. At this time, the hook part 230 can move toward the inside and outside of the outer shell 100 with the hook connection part 230a as the axis. That is, the hook connection part 230a can improve the mobility of the hook part 230.

[0202] The cover 200 may include a hook groove 221. Specifically, the handle portion 220 of the cover 200 may include a hook groove 221.

[0203] When the hook portion 230 is in the closed state, the second portion 232 will be locked in the hook groove 221 and the cover 200 will not be able to open. At this time, the upper movement of the cover 200 can be limited by the hook portion 230, and the lower movement can be limited by the cover edge 150. In this way, the state in which the cover 200 closes the external housing 100 can be maintained.

[0204] On the contrary, when the hook portion 230 is in the open state, it can move toward the inside of the external housing 100 without being caught by the hook groove 221 , so that the cover 200 is opened.

[0205] The cover 200 has a structure that can easily open the outer case 100 .

[0206] When a force in the inner direction of the outer housing 100 is applied to the first portion 231, the hook portion 230 may enter an open state. On the contrary, when the force applied to the first portion 231 disappears, the hook portion 230 may enter a closed state.

[0207] Thus, the user can lift the handle portion 220 of the cover 200 while pressing the first portion 231 of the hook portion 230 to open the cover 200 , and can easily open the cover 200 with the simple action as described above.

[0208] The cover 200 adopts a structure that can easily close the outer case 100 .

[0209] The embedding portion 210 may include a 1-1 sealing portion 211 , a 1-2 sealing portion 212 , and a 1-3 sealing portion. The outer housing 100 may include an embedding edge 160 . In this case, the embedding edge 160 may include a 2-1 sealing portion 161 and a 2-2 sealing portion 162 .

[0210] The 1-1 sealing portion 211 corresponds to a region that is recessed from the inner side of the cover 200 or the embedded portion 210 toward the outside of the cover 200. The 1-2 sealing portion 212 is formed by extending downward from the 1-1 sealing portion 211, and corresponds to a region that protrudes from the inner side of the cover 200 or the embedded portion 210 toward the inside of the cover 200. The 1-3 sealing portion 213 corresponds to a region that is extended downward from the 1-2 sealing portion 212 and inclined toward the outside of the cover 200.

[0211] In the structure in which the cover 200 seals the outer housing 100, the 1-1 sealing portion 211 and the 2-1 sealing portion 161 may be located in contact with or adjacent to each other. In this case, the 1-2 sealing portion 212 and the 2-2 sealing portion 162 may be located in contact with each other. In particular, the contact between the 1-2 sealing portion 212 and the 2-2 sealing portion 162 can prevent moisture from flowing into the first receiving space 101.

[0212] During the closing process, the 2-1st sealing portion 161 can move along the inclination of the 1-3rd sealing portion 213 and continue to move beyond the 1-2nd sealing portion 212 and stop on the 1-1st sealing portion 211. Since the 1-1st sealing portion 211 to the 1-3rd sealing portion 213 are formed by continuous bending, the 2-1st sealing portion 161 can be easily moved, thereby allowing the cover 200 to easily close the external housing 100.

[0213] In the opening process, the 2-1st sealing portion 161 may move in a manner opposite to the closing process described above.

[0214] In addition, the handle portion 220 may include a hook groove 221. The position of the groove 221 is not limited, and may be formed correspondingly at a position where the hook portion 230 can pass through.

[0215] The groove 221 may include a groove straight portion 221a and a groove inclined portion 221b. The groove straight portion 221a refers to a region located at the upper portion of the hook groove 221 and where the hook groove 221 maintains the same horizontal cross-sectional shape.

[0216] The groove inclined portion 221b is a region extending downward from the groove straight portion 221a and gradually increasing the horizontal cross-sectional width of the hook groove 221. At this time, the groove 221 can be composed of an inner surface and an outer surface, and the outer surface of the hook groove 221 can be gradually inclined toward the outer direction downward.

[0217] During the closing process, the hook portion 230 will pass through the hook groove 221 and the second portion 232 may be blocked by the upper surface of the handle portion 220 and combined with the hook groove 221. The second portion 232 may be formed to protrude toward the outside of the outer shell 100 compared to the first portion 231, and may be formed to be gradually inclined toward the inside of the outer shell 100 toward the upper portion. At this time, the hook inclined portion 232a refers to the inclined surface of the second portion 232.

[0218] The hook inclined portion 232a may contact the groove inclined portion 221b, so that the second portion 232 easily passes through the hook groove 221. The second portion 232 may pass through the hook groove 221 and be easily combined with the hook groove 221.

[0219] As described above, during the opening process, the user can easily release the engagement between the hook portion 230 and the hook groove 221 by lifting the handle portion 220 while pressing the first portion 231. Furthermore, the elastic force of the grip portion 310 of the inner housing 300 can be used to apply force to the cover 200 and thereby easily open the cover 200.

[0220] Next, the protrusion 400 of the inner case 300 or the outer case 100 will be described.

[0221] Figure 5 Schematic diagram illustrating a vertical protrusion 400 of an inner shell 300 according to an embodiment of the present invention. Figure 6 It is a schematic diagram illustrating the inner housing 300 and the air flow path 101a according to an embodiment of the present invention. Figure 7 The diagram is a schematic diagram illustrating an internal casing and an air flow path according to an embodiment of the present invention. Figure 8 Schematic diagram illustrating the threaded protrusion 400 of the inner shell 300 according to an embodiment of the present invention.

[0222] Re-read Figure 4aAccording to an embodiment of the present invention, the outer housing 100 may further include: a plurality of protrusions 400 formed on the inner surface of the outer housing 100. The protrusions 400 may form an air flow path 101a on the first receiving space 101 by contacting the outer surface of the inner housing 300 (see Figure 6 ).

[0223] The outer housing 100 may include a protrusion 400 (inner protrusion). The protrusion 400 may be formed to protrude inward from the inner surface of the outer housing 100. The protrusion 400 may be provided in plurality and formed in a vertical direction, but the number and shape thereof are not limited.

[0224] The protrusion 400 may come into contact with the outer surface of the inner case 300 and fix the inner case 300 to the outer case 100 by generating friction with the inner case 300 .

[0225] At this time, the outer surface of the inner case 300 may be formed smoothly. Smooth formation means that there is no protruding area on the outer surface of the inner case 300.

[0226] In addition, the protrusion 400 can form the air flow path 101a by contacting the outer surface of the inner case 300. When the inner case 300 is inserted into the outer case 100, the air inside the outer case 100 moves along the air flow path 101a and thereby easily induces the insertion of the inner case 300.

[0227] In contrast, in the case of separating the inner housing 300 from the outer housing 100 , air outside the outer housing 100 will move along the air flow path 101 a and thereby easily induce separation of the inner housing 300 .

[0228] The air flow path 101a formed by the protrusion 400 may be provided alone (including the case of providing a plurality of air flow paths) or may be provided together with the pressurization slit 119 formed on the lower surface of the outer housing 100. In this case, the pressurization slit 110 may be formed in a hole structure or a slit structure. In addition, the air flow path 101a may be divided into a plurality of parts by means of a plurality of protrusions 400.

[0229] At this time, the air flow path 101 a can maintain the first receiving space 101 of the outer housing 100 at the same air pressure as the outside, thereby easily completing the separation and insertion of the inner housing 300 .

[0230] See also Figure 5 as well as Figure 6According to an embodiment of the present invention, the inner housing 300 may include: a plurality of protrusions 400 formed on the outer surface of the inner housing 300. The protrusions 400 may form an air flow path 101a on the first receiving space 101 by contacting the inner surface of the outer housing 100.

[0231] The inner housing 300 may include a protrusion 400 (outer protrusion). The protrusion 400 may be formed to protrude outward from the outer surface of the inner housing 300. The protrusion 400 may be provided in plurality and formed in a vertical direction, but the number and shape thereof are not limited.

[0232] The protrusion 400 may come into contact with the inner surface of the outer case 300 and fix the inner case 300 to the outer case 100 by generating friction with the outer case 300 .

[0233] At this time, the inner surface of the outer case 100 may be formed to be smooth. The smooth formation means that there is no protruding area on the inner surface of the outer case 100.

[0234] Furthermore, the protrusion 400 may form the air flow path 101a by contacting the inner surface of the outer case 100. At this time, as described above, the protrusion 400 may exist together with the pressurization slit 110 provided on the lower surface of the outer case 100, or may exist alone.

[0235] See also Figure 7 According to an embodiment of the present invention, the outer surface of the inner shell 300 may be formed in a polygonal column shape. The edges of the outer surface may contact the inner surface of the outer shell 100 to form an air flow path 101a in the first receiving space 101.

[0236] The outer surface of the inner shell 300 may be formed in a cylindrical shape or in a polygonal column shape. Figure 7 The case where the outer surface of the inner shell 300 is configured in the shape of a twelve-prism is only one embodiment, and the present invention is not limited thereto, but may be configured in various forms.

[0237] When the outer surface of the inner case 300 is formed in a polygonal column shape, the edges of the outer surface may contact the inner surface of the outer case 100. In this case, the edges may form an air flow path 101a inside.

[0238] Furthermore, the inner surface of the outer shell 100 may be cylindrical or polygonal. When the inner surface of the outer shell 100 is cylindrical, the edges of the outer surface of the inner shell 300 may contact the inner surface of the outer shell 100 to form an air flow path 101a in the first receiving space 101.

[0239] In contrast, when the inner surface of the outer shell 100 is formed in the same shape as the inner surface of the outer shell 100, the outer surface of the inner shell 300 and the inner surface of the outer shell 100 will contact each other, and the edges of the outer surface of the inner shell 300 and the edges of the inner surface of the inner shell 300 may also contact each other.

[0240] At this time, although the air flow path 101a is not formed, the flow of air can be induced by the pressurized gap 110 of the hole structure formed on the lower surface of the outer housing 100. In the above case, the inner housing 300 can be fixed to the outer housing 100 more firmly.

[0241] See also Figure 8 According to an embodiment of the present invention, the inner shell 300 may include: a protrusion 400 formed in a threaded shape on the outer surface of the inner shell 300.

[0242] The inner housing 300 may include a protrusion 400 (threaded protrusion). The protrusion 400 may be formed to protrude from the outer surface of the inner housing 300. At this time, the outer housing 100 may include a thread groove (not shown). The thread groove may be formed to be recessed from the inner surface of the outer housing 100.

[0243] The protrusion 400 of the inner housing 300 and the thread groove of the outer housing 100 may form a threaded connection, so that the inner housing 300 can be inserted into or separated from the outer housing 100 by means of the threaded connection.

[0244] Different from the above, the outer housing 100 may include the protrusion 400 and the inner housing 300 may include the thread groove.

[0245] In the case as described above, the inner case 300 may be more firmly fixed to the outer case 100 .

[0246] As another embodiment, the protrusion 400 provided on the inner shell 300 may be formed along the periphery of the upper end of the inner shell, and may be extended from the upper end in a plurality of vertical lines, and the plurality of lines may be extended to the lower surface of the inner shell 300 (see Fig. 9 ).

[0247] Next, the structures of the fixing edge 140 of the outer housing 100 and the fixing groove 320 of the inner housing 300 will be described.

[0248] Fig. 9 2 is a schematic diagram illustrating the fixing groove 320 of the inner shell 300 according to an embodiment of the present invention. Fig.102 is a schematic diagram illustrating the fixing groove 140 of the external housing 100 according to an embodiment of the present invention. Fig.11a It is a schematic diagram illustrating the combined state of the fixing groove 320 and the fixing edge 140 according to an embodiment of the present invention. Fig.11b It is a schematic diagram illustrating the separation state of the fixing groove 320 and the fixing edge 140 according to an embodiment of the present invention.

[0249] See also Fig. 9 as well as Fig.10 According to an embodiment of the present invention, the outer shell 100 may further include a fixing edge 400 formed along a vertical direction on the inner surface and used to fix the inner shell 300. The inner shell 300 may include a fixing groove 320 on the outer surface through which the fixing edge 140 can pass. The fixing groove 320 may be formed in a manner that the depth gradually decreases from the upper part to the lower part of the inner shell 300.

[0250] The outer shell 100 may include a fixing edge 140 formed on the inner surface. The fixing edge 140 may be formed along the vertical direction on the inner surface of the outer shell 100. As a corresponding configuration, the inner shell 300 may include a fixing groove 320 formed on the outer surface. The fixing groove 320 may be formed on the outer surface of the inner shell 300 along the vertical direction.

[0251] The fixing edge 140 and the fixing groove 320 may be formed to correspond to each other, so that the inner housing 300 is combined with and separated from the outer housing 100 in a state where the fixing edge 140 contacts the fixing groove 320. At this time, the inner housing 300 can be separated from the outer housing 100 only by translation or sliding motion.

[0252] The fixing groove 320 may be formed in such a manner that the depth gradually becomes shallower from the upper portion to the lower portion of the inner case 300. With the above-described structure, the inner case 300 may be firmly fixed when the inner case 300 is completely inserted into the outer case 100.

[0253] In contrast, when the inner case 300 is almost separated from the outer case 100 (before being completely separated), the inner case 300 can be easily separated from the outer case 100 .

[0254] See also Fig.11a , the inner housing 300 cannot rotate in the fully inserted state, but can only perform translational movement or sliding movement. The above effect can be presented when the fixing edge 14 enters the upper fixing groove 320 formed with a relatively deep depth. In the fully combined state as described above, the inner housing 300 can be firmly fixed to the outer housing 100.

[0255] See also Fig.11b The inner housing 300 can rotate in a state of being almost separated, and can also perform translational motion or sliding motion. The above-mentioned effect can be presented when the fixing edge 14 enters the lower fixing groove 320 formed with a relatively shallow depth. In the state of being almost separated as described above, the inner housing 300 can perform rotational motion and be easily separated from the outer housing 100.

[0256] Furthermore, the fixing groove 320 may be formed with a shallower depth toward the lower portion of the inner housing 300, and the fixing groove 320 may disappear at the lowermost end. In this way, the inner housing 300 may be formed into a structure that can freely rotate and move before being completely separated from the outer housing 100. That is, from the upper region 320a to the lower region 320b of the fixing edge 140, its depth may be gradually reduced continuously or discontinuously.

[0257] In addition, different from the above, the inner housing 300 may include the fixing edge 140 and the outer housing 200 may include the fixing groove 320. In this case, the insertion and separation process of the inner housing may be the same as described above.

[0258] In the process of inserting the inner case 300 , the inner case 300 may be gradually firmly fixed to the outer case 100 , and in the process of separating the inner case 300 , may be gradually freely separated from the outer case 100 .

[0259] Next, the grip portion 310 provided in the inner housing 300 will be described.

[0260] Fig.12a Schematic diagram showing the gripping portion 310 in a bent state according to an embodiment of the present invention. Figure 12b It is a schematic diagram illustrating the changes of the holding portion 310 according to the embodiment of the present invention. Fig.12c This is a schematic diagram illustrating a state in which the grip portion prevents the cover from closing according to an embodiment of the present invention.

[0261] See also Figure 3a , Figure 5 as well as Fig.11a According to an embodiment of the present invention, the inner shell 300 may include a gripping portion 310 protruding from an upper end portion for a user to grip.

[0262] In addition, the upper end of the inner housing 300 according to the embodiment of the present invention may be formed to be inclined downward from the first height h1 to the second height h2. The holding portion 310 may be formed to be extended upward at the second height h2.

[0263] The grip portion 310 may be formed to extend from the upper end portion of the inner housing 300. In particular, the grip portion 310 refers to a portion that can be gripped by a user in order to easily separate the inner housing 300 from the outer housing 100.

[0264] Re-read Figure 5 , the first height h1 may refer to the highest upper end of the side of the inner case 300, and the second height h2 may refer to the lowest upper end of the side of the inner case 300. That is, the upper end of the inner case 300 may be formed to be inclined downward from the first height h1 to the second height h2.

[0265] With the aid of the above-mentioned inclined structure, even if the grip portion 310 is long, the grip portion 310 can be prevented from protruding upward and outward when the lid 200 is closed. The grip portion 310 is equivalent to a portion that can be gripped by a user. If its length is too short, it will not be able to perform its function, so it can be formed to protrude from the second height h2.

[0266] The entire grip portion 310 may be located below the upper end of the external housing 100, or a portion of the grip portion 310 may be located protruding above the upper end of the external housing 100. The latter will be described in the following content.

[0267] In addition, the upper end of the grip 310 may be located at the same height as the upper end of the outer case 100. In this case, the upper end of the grip 310 may contact the cover 200 and thereby fix the inner case 300 in the upper and lower directions inside the outer case 100.

[0268] In addition, the first height h1 refers to the highest position on the side of the inner shell 300 (excluding the gripping portion 310), and by means of the inclined structure as described above, it is possible to ensure that the space in contact with the medicine, namely the second receiving space 301, reaches the maximum width.

[0269] Thus, the internal shell 300 can be equipped with a handle portion 310 whose upper end is inclined from a first height h1 to a second height h2 and extends upward at the second height h2, thereby providing a structure in which the handle portion 310 provides a sufficient length for the user to hold while not protruding to the outside of the external shell 100.

[0270] See also Figure 8 , Fig.11a as well as Fig.11b According to an embodiment of the present invention, the holding portion 310 may include: a holding groove 311 formed on at least one of the outer surface and the inner surface of the holding portion 310.

[0271] In addition, according to the embodiment of the present invention, the handle 310 may be at least partially exposed to the upper portion of the external shell 100 when inserted into the external shell 100 .

[0272] The holding portion 310 may include a holding groove 311. The holding groove 311 may be formed on the outer surface and / or the inner surface of the holding portion 310. That is, the holding groove 311 may be formed only on the outer surface of the holding groove 311, may be formed only on the inner surface, or may be formed on both the inner surface and the outer surface.

[0273] The holding groove 311 may be in the shape of being recessed inward from one side of the holding portion 310. Figure 8 As shown, the holding groove 311 can be formed to maintain the same width throughout the depth, and at least one holding groove 311 can be provided. However, the shape and number of the holding groove 311 are not limited to Figure 8 .

[0274] In contrast, Fig.11a as well as Fig.11b As shown, the holding groove 311 can be formed in a manner that the width gradually narrows in the depth direction, and at least one can be provided. In the above case, the holding portion 310 when viewed from the side can present a plurality of curved shapes by means of the holding groove 311. That is, the holding groove 310 repeatedly constitutes a convex area and a concave area.

[0275] The holding groove 311 can increase the holding area of ​​the holding portion 310 when the user holds it, so as to easily separate the inner shell 300 .

[0276] See also Fig.12a as well as Figure 12b According to an embodiment of the present invention, the holding portion 310 may be elastic. The holding portion 310 may be bent toward the second receiving space 301 of the inner shell 300 when the cover 200 is closed. The holding portion 310 may return to a basic state when the cover 200 is opened.

[0277] The holding portion 310 may be elastic and may include a holding groove 311. Fig.11a as well as Fig.11b , the holding portion 310 can maintain a straight line as a basic state. Even if the holding portion 310 is temporarily bent due to elasticity, it can also return to the basic state. That is, the holding portion 310 can be elastically deformed and can return to the basic state when the external force disappears.

[0278] See also Fig.12a, the grip portion 310 can be bent by the cover 200 when the outer housing 100 is closed. The grip portion 310 can be formed long so that the user can easily hold the inner housing 300. At this time, even if the grip portion 310 protrudes outside the outer housing 100, it can be bent by the cover 200 and the opening 100a of the outer housing 100 can be closed. In the above case, the elastic force of the grip portion 310 can be smaller than the bonding force between the cover 200 and the outer housing 100.

[0279] See also Figure 12b , the holding portion 310 can eliminate the bending by elastic force when the outer shell 100 is opened. At this time, the elastic force of the holding portion 310 can apply force to the cover 200, so that the cover 200 can be opened more easily.

[0280] See also Fig.12c The grip portion 310 may protrude toward the outside of the external housing 100 , thereby preventing the cover 200 from being accidentally closed when the opening portion 100 a of the external housing 100 is open.

[0281] Thus, the user can disengage the hook portion 230 from the loop portion 130 with a single touch, thereby completely opening the cover 200 through the grip portion 310. That is, a one-touch opening method can be achieved.

[0282] With the aid of the structure described above, the holding portion 310 can be formed with a sufficient length to prevent the cover 200 from being accidentally closed. Although it is formed with a sufficient length, it is flexible and can be bent toward the second receiving space 301 to easily close the external shell 100. It can also achieve the effect of one-touch opening of the cover 200 through elastic force.

[0283] In addition, refer to Fig. 9 According to an embodiment of the present invention, the inner shell 300 may include: two fixing grooves 320 formed to at least a portion of the height of the outer surface of the inner shell 300; and two fixing slits 330 formed from the portion of the height of the inner shell 300 in a manner corresponding to the fixing grooves 320. The holding portion 310 may be located between the portion of the height and the two fixing slits 330. In addition, the inner shell 300 may further include a flat portion 340 between the two fixing slits 330.

[0284] As described above, the inner housing 300 may include a fixing groove 320 on the outer surface. Specifically, the inner housing 300 may include two fixing grooves 320 formed parallel to each other in a vertical direction. At this time, the fixing groove 320 may be formed to at least a portion of the height of the inner housing 300.

[0285] In addition, the inner housing 330 may include two fixing slits 330 formed from at least a portion of the height. At this time, the fixing slits 330 may be formed at positions corresponding to the fixing grooves 320. Here, corresponding means that when an imaginary extension line is formed from the fixing grooves 320 formed in the vertical direction, the fixing slits 330 are formed along the extension line.

[0286] That is, the fixing groove 320 starting from the lower end of the inner case 300 may be extended to at least a portion of the height, and the fixing slit 330 starting from at least a portion of the height may be extended to the upper end of the inner case 300 .

[0287] At this time, the holding portion 310 may be extended upward from at least a portion of the height, and the holding portion 310 may be located between the two fixing slits 330 .

[0288] By positioning the grip portion 310 between the fixing slits 330 , a longer grip portion 310 can be formed. Furthermore, by forming a longer grip portion 310 , the gripping area of ​​the user can be further expanded, and the risk of breakage of the grip portion 310 when bent can be reduced.

[0289] The inner housing 300 may include a flat surface portion 340. The inner housing 300 is not limited to a shape such as a prism or a cylinder, but even when the inner housing 300 is configured in a cylindrical shape, it may include a flat surface portion 340 in at least a portion.

[0290] The plane portion 340 may be located between the two fixing slits 330, and the grip portion 310 may be formed from the upper end of the plane portion 340. At this time, since the upper end of the plane portion 340 is formed in a straight line, the connection between the grip portion 310 and the plane portion 340 may also be formed in a straight line. Thus, the grip portion 310 can be easily converted into a bent state and a basic state.

[0291] The environmentally friendly container 1 according to the embodiment of the present invention can be made of environmentally friendly materials and can be recycled. In addition, the environmentally friendly container 1 can be constructed in a structure that is easy to separate, so that users can easily classify and recycle materials.

[0292] In addition, the outer case 100 is provided with the embedding edge 160 , and the cover 200 is provided with the embedding portion 210 , so that the inflow of moisture into the first receiving space 101 and the second receiving space 301 can be prevented by being combined with each other.

[0293] Furthermore, the inner housing 300 is provided with a gripping portion 310, so that it can be easily separated from the outer housing 100. In addition, the gripping portion 310 can be formed to protrude outside the opening portion 100a provided on the outer housing 100, thereby increasing the area available for the user to grip, and can prevent the cover 200 from being accidentally closed, and further can also achieve the effect of a one-touch opening of the cover 200 by elastic force.

[0294] The above content describes the preferred embodiments of the present invention, but a person skilled in the art can make various modifications and variations to the present invention without departing from the concept and spirit of the present invention as described in the appended claims.
