Description

Technical Field

[0001] The present invention relates to a stopper and a container having a stopper, and more specifically, to a stopper having a barrier membrane and a container having a stopper, wherein the barrier membrane separates and contains different types of contents before the stopper is opened, and when the stopper is opened and the contents are taken in, different types of contents can be taken in at the same time. Background Technology

[0002] Bottles and other containers used to hold various beverages or condiments are very useful to modern people.

[0003] In this type of container, a container with a functional plug that can be separated and contained has been developed and marketed. This functional plug has a separate separation space that is distinct from the internal space of the container body.

[0004] The stopper has a separation space to accommodate contents that are different in form from the contents of the main container (e.g., the main contents) (e.g., secondary contents).

[0005] Therefore, in order to ingest the main contents of the container, when the user opens the plug attached to the container and ingests the main contents, the secondary contents in the plug will also be ingested at the same time.

[0006] However, due to sealing issues in the separation space of the stopper containing the secondary contents, the main contents of the container body, which is primarily composed of liquid, can mix with the secondary contents of the stopper.

[0024] Each auxiliary part can have a fan-shaped planar shape.

[0025] The damaged protrusion may have multiple wings spaced at a predetermined angle from each other, and the height of the ends of the multiple wings may be the same.

[0026] The damaged portion may also include a central portion that connects to the plurality of wings and extends downward from the upper surface of the plug.

[0027] The height of the end of the central portion may be lower than the height of the end of each of the wings.

[0028] Each wing is located between two adjacent auxiliary body sections and may be opposite a portion of the exposed barrier membrane.

[0029] Each wing can be opposite to each auxiliary body.

[0030] The connecting strip may include a groove formed along its width.

[0031] The descent aid may be made of the same material as the blocking membrane position portion.

[0032] The descent aid may be made of a different material than the barrier membrane.

[0033] At least a portion of the barrier membrane location may be formed of a resin material, and a portion of the barrier membrane is located inside the resin material, the portion being embedded within the resin material.

[0034] The blocking membrane position portion can be inclined inward from the upper part of the cover body, with an opening in the middle portion. The blocking membrane is located at the opening portion of the blocking membrane position portion and can block the opening portion.

[0035] The blocking membrane position portion can be arranged parallel to the adjacent cover body, with an opening in the middle. The blocking membrane is located at the opening portion of the blocking membrane position portion and can block the opening portion.

[0036] The upper part of the barrier membrane location portion may be thicker than the lower part, and the upper part of the barrier membrane location portion may be connected to the adjacent container body.

[0037] According to another feature of the invention, the stopper includes: a cap portion, which is coupled to a container body having an injection port, and a damage portion, which is coupled to the cap portion. The cap portion includes: a cap portion body, coupled to the container body; a barrier film position portion, coupled to the cap portion body; and a barrier film, located at the barrier film position portion. The damage portion includes: a damage portion body, located at the upper part of the container body; and a damage protrusion, coupled to the damage portion body, which damages the barrier film by moving downward from the damage portion body. The barrier film position portion includes a coupling portion coupled to the barrier film, and the barrier film includes: a coupling surface, coupled to the coupling portion; a central surface, forming the inner side of the coupling surface; and an outer extending surface, extending outward from the coupling surface.

[0038] The cover portion may also include a descent aid portion located below the barrier membrane and assisting in the descent of the barrier membrane.

[0039] The lowering auxiliary part may include: at least one auxiliary part body located at a position in contact with the barrier membrane; and a connecting strap disposed at predetermined intervals along the edge portion of the at least one auxiliary part body, thereby connecting the at least one auxiliary part body to the cover body or the barrier membrane position portion.

[0043] The cover portion may further include an inclined surface formed on the outside of the joint portion, inclined downward toward the center of the barrier membrane, and the outer extension surface may extend inclinedly along the inclined surface.

[0044] Containers according to other features of the invention include stoppers according to said features.

[0045] Invention Effects

[0046] Based on this feature, since the contents of different types, respectively contained in the container body and the stopper, do not mix and are preserved in their original quality, the shelf life of the contents can be increased.

[0047] In addition, since the barrier membrane is firmly located in the container body, it can prevent the barrier membrane from being damaged during circulation.

[0048] Furthermore, since the ends of the barrier membrane are designed to be inserted into the container body, the barrier membrane containing metals such as aluminum can be prevented from oxidizing when exposed to air or moisture.

[0049] Furthermore, since the barrier membrane is inserted into and shaped at the barrier membrane location, the barrier membrane is embedded in the barrier membrane location, which makes the connection structure between the barrier membrane and the barrier membrane location very simple.

[0050] Furthermore, the convenience for users is greatly enhanced by the simple action of pressing the protruding part to drop the contents into the main body of the container.

[0051] Furthermore, the presence of a descent aid on the barrier membrane accelerates the descent of the damaged barrier membrane, and the increased opening of the injection port in the container body allows the contents of the stopper to descend more easily into the container body. This reduces the amount of contents lost from the stopper and further improves user convenience. Attached Figure Description

Unless otherwise specified in the drawing reference numerals, the same or similar constituent elements are given the same reference numerals, and repeated descriptions thereof are omitted. Furthermore, when describing embodiments disclosed in this specification, if it is determined that detailed descriptions of related well-known technologies would obscure the key points of the embodiments disclosed in this specification, such detailed descriptions are omitted.

[0081] Ordinal terms such as first, second, etc., may be used when describing multiple constituent elements, but the constituent elements are not limited by the terms. The terms are used only for the purpose of distinguishing one constituent element from other constituent elements.

[0082] Singular expressions include plural expressions unless explicitly defined otherwise in the context.

[0083] In this application, except where the steps must be performed in a specific causal order, each step described may be performed regardless of the order of execution.

[0084] In this application, terms such as "comprising" or "having" specify the presence of features, numbers, steps, actions, constituent elements, components, or combinations thereof as described in the specification, and should be understood to preclude the presence or possibility of one or more other features or numbers, steps, actions, constituent elements, components, or combinations thereof.

[0085] Hereinafter, a container with a stopper according to an embodiment of the present invention will be described.

[0086] The container 1 in this example has a stopper 100 and a container body 200. The container body 200 is connected to the stopper 100 by a connecting portion 202 having threads 2021 on the outer side of the side.

[0087] The stopper 100 is attached to the joint 202 of the container body 200 to prevent the contents (e.g., the main contents) contained in the internal space S200 of the container body 200 from flowing out through the inlet 204.

[0088] As an example, the main contents of the internal space S200 of the container body 200 can be a liquid substance.

[0089] like Figure 2 As shown, the stopper 100 may have a cap portion 110 that is coupled to the joint portion 202 of the container body 200 and a damage portion 120 located on the upper part of the cap portion 110 and coupled to the cap portion 110.

[0090] The cap portion 110 can be threaded into the joint portion 202 of the container body 200, and the injection port 204 can be sealed or opened by rotation.

[0091] Therefore, by blocking the inlet 204 of the container body 200 with the cover portion 110, the main contents contained in the container body 200 can be prevented from flowing out.

[0092] like Figure 3 and Figure 4 As shown, this cover portion 110 may include: a cover portion body 111, which may have a circular planar shape; a sealing portion 112, which protrudes downward from the upper part of the cover portion body 111; a barrier film position portion 113, which is inclinedly disposed on the upper surface of the cover portion body 111; a barrier film 114, which is located at the barrier film position portion 113; a lowering auxiliary portion 115, which is located above the barrier film 114; and a connecting portion 116, which is used to connect with the damaged portion 120.

[0093] The lid body 111 can be joined to the container body 200 by joining it to the container body 200 via the joint 202.

[0094] like Figure 2 As shown, the main body 111 of the cover portion may have: a side surface having a circular planar shape; and an upper surface, one end of which can be connected to the side surface and the other end of which is connected to the barrier membrane position portion 113.

[0095] At this time, the blocking membrane position part 113 can be located in the upper middle part of the cover body 111, and the upper surface of the cover body 111 can only be located in the upper edge part of the cover body 111.

[0096] In order to be combined with the container body 200, the cover body 111 may have threads 1111 on the inner side (i.e., the inner side) so that it can be threadedly combined with the joint 202 of the container body 200.

[0097] By combining the main body 111 of the cover with the main body 200 of the container, the inlet 204 of the opening of the container 200 is blocked by the cover 110, so that the main contents contained in the container 200 do not flow out to the outside and can be stored in the internal space S200 of the container 200.

[0098] Additionally, when necessary, the user can unscrew the lid body 111 from the container body 200 by rotating it in a specified direction, thereby opening the injection port 204 and allowing the contents of the container body 200 to be taken in.

[0099] like Figure 2As shown, the sealing part 112 can extend from the inner surface (i.e., the inner upper surface) of the upper membrane of the cover body 111 in the downward direction, i.e., towards the container body 200.

[0100] At this time, the sealing part 112 can be located at a predetermined distance from the inner side of the cover body 111, and can have a wall shape with a circular planar shape extending vertically downward relative to the inner upper surface.

[0101] The extension length of the sealing portion 112 extending downward can be much shorter than the extension length of the side of the cover body 111.

[0102] like Figure 2 As shown, this sealing part 112 can be tightly attached to a portion of the inner side surface of the container body 200, which is connected to the lid body body 111.

[0103] Therefore, when the container body 200 is combined with the lid body 111, the sealing part 112 is in close contact with the inner side of the container body 200 and applies pressure to the inner side of the container body 200.

[0104] Therefore, the connection between the lid body 111 and the container body 200 can be maintained more securely and firmly, thereby improving the stability of the connection structure and greatly enhancing the sealing force on the main contents contained inside the container body 200, thus increasing the circulation period of the container 1.

[0105] As described above, since the container body 200 is located between the inner side of the lid body 111 and the sealing portion 112, the spacing distance of the sealing portions 112 from the inner side of the lid body 111 can be determined based on the side thickness of the container body 200 including the thread 2021.

[0106] In an alternative example, this sealing part 112 can be omitted.

[0107] In this example, since the cover portion 110 may contain a material such as elastic plastic, the spacing of the sealing portions 112 from the inner side of the cover portion body 111 may be the same as or smaller than the side thickness of the container body 200 including the thread 2021.

[0108] As described above, the barrier film position portion 113 is continuously connected to the other end of the upper surface of the cover body 111, and can extend downward.

[0109] At this time, as Figure 2As shown, in this example, the barrier film position portion 113 can be inclined in a diagonal line from the outside, i.e., the upper surface of the cover body 111, to the inside, i.e., the downward auxiliary portion 115. In this case, the angle formed between the surface on which the container 1 is provided and the barrier film position portion 113 can be less than 90 degrees, the diameter of the barrier film position portion 113 decreases downward, and it can have a circular planar shape with an opening in the middle.

[0110] However, in an alternative example, the barrier membrane location portion 113 is connected to the upper part of the cover body 111 and may extend in parallel with the adjacent portion of the cover body 111, more specifically, the side of the cover body 111, in a downward direction. In this case, the angle formed between the mounting surface of the container 1 and the barrier membrane location portion 113 may be approximately 90 degrees. Regardless of its position, the barrier membrane location portion 113 has the same diameter and may have a circular planar shape with an opening in the middle.

[0111] Therefore, as Figure 2 As shown, the barrier membrane 114 can be located at the other end of the barrier membrane position portion 113, which is a free end that is not connected to the cover body 111.

[0112] The barrier membrane 114 is located in the middle part of the barrier membrane position portion 113 of the opening, and can be a thin film with a circular planar shape that can completely seal the barrier membrane position portion 113 of the opening.

[0113] Therefore, since the middle part of the barrier membrane position portion 113, which communicates with the internal space S200 of the container body 200, is completely blocked by the barrier membrane 114, the injection port 204 will not open until the barrier membrane 114 is damaged or the cap body 111 is separated from the container body 200, so the main contents inside the container body 200 cannot flow into the stopper 100 side.

[0114] Through this barrier membrane 114, a sealed space S100 can exist, which is enclosed by the cover portion 110, the damaged portion 120 and the barrier membrane 114, and a secondary content different from the main content can exist in the sealed space S100.

[0115] In this example, the secondary contents can be solid contents, such as in powder or capsule form.

[0116] As described above, since there is another sealed space S100 that is physically separated from the internal space S200 of the container body 100 by the barrier membrane 114, the secondary contents can be safely stored in the space S100 without mixing with the main contents.

[0117] In this example, the barrier film 114 may contain a metallic material such as aluminum.

[0118] like Figure 2 As shown, a portion of the edge of the barrier membrane 114 can be inserted into the adjacent barrier membrane position portion 113, and the diameter of the barrier membrane 114 can be larger than the diameter of the middle portion of the open barrier membrane position portion 113.

[0119] Therefore, since there can be a groove for inserting the blocking membrane 114 in the blocking membrane position portion 113, and the groove is completely filled with the material of the blocking membrane position portion 113, the blocking membrane 114 can be integrally combined with and provided in the groove of the blocking membrane position portion 113.

[0120] This barrier membrane 114 can be installed by inserting it into a portion of the cover portion 110 via injection molding.

[0121] For this purpose, the part of the cover portion 110 into which the barrier film 114 is inserted can be made of resin material. The barrier film 114 can be located in the cover portion 110 made of resin material, for example, in a groove formed along with the edge portion of the barrier film position portion 113, thereby combining with the barrier film position portion 113, which is part of the cover portion 110.

[0122] Therefore, as Figure 2 As shown, a portion of the blocking membrane 114, for example, an edge portion, can be inserted into the edge portion of the blocking membrane position portion 113 and integrally disposed with the blocking membrane position portion 113.

[0123] Therefore, since the risk of the barrier membrane 114 inserted into the barrier membrane position portion 113 falling out of the groove can be greatly reduced, the barrier membrane 114 can be safely and securely located in the corresponding position of the barrier membrane position portion 113.

[0124] The upper and lower surfaces of the barrier membrane 114 containing metallic substances can be coated with a hygienic and safe coating material to prevent oxidation, etc.

[0125] That is, the barrier film 114 can be manufactured by cutting a barrier film sheet with a coating on its upper and lower surfaces into a circular sheet with a desired diameter.

[0126] Therefore, the side of the barrier film 114, which is the cut surface, is the part without coating. When this part without coating comes into contact with air or moisture, oxidation will occur, and the metal components contained in the barrier film 114 will flow out to the outside.

[0127] However, as shown in this example, the side of the uncoated barrier film 114 flows into the barrier film location portion 113 via insert injection molding, and can be integrally formed with and embedded in the barrier film location portion 113. Therefore, since the side of the barrier film 114 is blocked from contact with oxygen or moisture, oxidation can be prevented, and the components of the barrier film 114 are prevented from flowing out.

[0128] In addition, due to the molding of the barrier membrane position portion 113, the phenomenon of the barrier membrane 114 detaching from the barrier membrane position portion 113 can be prevented. As a result, the main contents contained in the container body 200 and the secondary contents contained in the stopper 100 can be safely separated and stored.

[0129] However, in an alternative example, the barrier membrane 114 can be attached to the lower end of the barrier membrane location portion 113 and set using an adhesive or the like.

[0130] The descent assist 115 is located on the barrier membrane 114 and is used to apply a load to the lower side of the barrier membrane 114, that is, the inner side of the container body 200.

[0131] Therefore, when the barrier membrane 114 is damaged due to the action of the damage section 120 and the connection with the barrier membrane position section 113 is released, the barrier membrane 114 falls more easily into the container body 200 due to the weight of the lowering auxiliary section 115. Thus, the opening action of the injection port 204 blocked by the barrier membrane 114 can be performed more quickly and accurately.

[0132] As an example, this descent aid 115 can be manufactured integrally with the barrier film position portion 113. In this case, the descent aid 115 can be made of the same material as the barrier film position portion 113. However, in an alternative example, the descent aid 115 can be made of a different material than the barrier film position portion 113. In this case, the descent aid 115 can be bonded to the corresponding portion of the barrier film position portion 113 by heat treatment or the like.

[0133] like Figures 5 to 6c As shown, the lowering auxiliary part 115 may include: an auxiliary part body 1151 having the same planar shape as the lower blocking membrane 114, and being circular; and a plurality of connecting straps 1152 for connecting the auxiliary part body 1151 to an adjacent cover part body 111 or blocking membrane position part 113.

[0134] The auxiliary part body 1151 can be composed of a part having a variety of planar shapes, such as a circle.

[0135] Multiple connecting strips 1152 are provided at predetermined intervals along the edge of the circular auxiliary part body 1151, and can be radially connected to the barrier membrane position part 113 at the edge of the auxiliary part body 1151.

[0136] One of the multiple connecting strips 1152 is damaged along with the lower barrier membrane 114 by the action of the damage part 120, thereby breaking the connection with the barrier membrane position part 113, thus enabling the opening of the injection port 204 of the container body 200 blocked by the barrier membrane 114.

[0137] As described above, this descent aid 115 is located on the barrier film 114 and can be attached to the barrier film 114.

[0138] At this time, since the edge portion, which is part of the blocking film 114, can be inserted into the adjacent blocking film position portion 1113, such as Figures 6a to 6c As shown, the barrier membrane 114 may include: a middle portion 114a, which is a portion located in the sealing space S100 within the damaged portion 120; and an edge portion 114b, which is a portion located within the barrier membrane position portion 113.

[0139] As an example, multiple connecting strips 1152 can have the same shape, such as Figure 6c As shown, each connecting strip 1152 may have a slot 11521, which is provided along the configuration direction of the plurality of connecting strips 1152 (e.g., the width direction of the connecting strips 1152) W1.

[0140] Therefore, the portion of the connecting strip 1152 where the groove 11521 is located can have a thinner thickness than the portion of the connecting strip 1152 without the groove.

[0141] Therefore, the strength of the connecting strip 1152 where the groove 11521 is located can be weaker than the strength of the connecting strip 1152 without the groove.

[0142] Therefore, when force is applied from the upper part of the connecting belt 1152, the disconnection action can be performed more accurately by applying force because the disconnection action can be performed more easily in the groove 11521 of the connecting belt 1152.

[0143] like Figure 2 As shown, the connecting part 116 protrudes from the outer side of the upper surface of the cover body 111 (that is, the upper surface located on the opposite side of the inner upper surface, referred to as the "outer upper surface") toward the damaged part 120 in the upward direction, and can be connected continuously in a circular manner along the upper surface of the circular cover body 111.

[0144] This joint 116 may have threads 1161 on its outer side to engage with the damaged part 120.

[0145] Therefore, the damaged part 120 can be located on the upper surface of the cover body 111 by threading with the connecting part 116.

[0146] Secondly, refer to Figures 2 to 4 The damaged part 120 will be explained.

[0147] As described above, the damaged part 120 allows the secondary contents in the sealed space S100 to flow into the internal space S200 of the container body 200 by damaging a portion of the barrier membrane 114 that blocks the injection port 204, thereby allowing them to mix with the main contents.

[0148] This damaged part 120 may include a damaged part body 121 and a damaged protrusion 124 connected to the damaged part body 121.

[0149] In this example, at least one of the tilt angle θ1 and shape of the damaged part 120 can change in the initial state, i.e., when no physical force is applied to the upper part of the damaged protrusion 124.

[0150] The damaged part body 121 may include: a main body side 1211, which is connected to the cover part 110, more specifically, to the joint part 116; and a damaged part upper surface 1212, which is connected to the main body side 1211 and extends from the main body side 1211, and at least one of the tilt angle θ1 and shape changes due to a force applied from the outside.

[0151] The main side 1211 may have a shape that extends upward, then inward, and then downward.

[0152] In this case, the main body side 1211 may include: a first side portion 1211a, which extends upward in a height direction (e.g., longitudinally) that is perpendicular to the mounting surface; an upper surface 1211b, which is continuously connected to the first side portion 1211a and extends inward in a planar direction (e.g., laterally) that is parallel to the mounting surface; and a second side portion 1211c, which descends downward in the height direction at the end of the upper surface 1211b, which is a free end not connected to the first side portion 1211a.

[0153] At this time, the middle part of the upper surface 1211b is open, so that there can be an empty space in the middle. There can be an empty space surrounded by the second side portion 1211c of the main body side 1211, and the upper surface 1212 of the damaged part can be located in this space.

[0154] The upper surface 1212 of the damaged portion can cover at least a portion of the upper surface 1211b of the opening of the damaged portion 120 and is connected to at least one damaged protrusion 124, thereby allowing at least one damaged protrusion 124 to be provided.

[0155] One end of the upper surface 1212 of the damaged part can be connected to the edge of the upper surface 1241 of the damaged protrusion 124, and the other end can be located at the lower part of the second side surface 1211c.

[0156] At this time, since the height of the upper surface 1241 of the damaged protrusion 124 is higher than the height of the lower part of the second side portion 1211c, the upper surface 1212 of the damaged portion can tilt from the upper surface 1241 of the damaged protrusion 124 towards the lower side of the second side portion 1211c when in the initial state.

[0157] Therefore, the upper surface 1212 of the damaged portion can be a convex surface with a circular planar shape that protrudes upward and connects to one side (i.e., the free end) of the lower part (specifically the second side part 1211c) of the main body side 1211. The middle part of such an upper surface 1212 of the damaged portion can be hollow.

[0158] Therefore, the damaged protrusion 124 can be located in an empty space of the damaged part body 121, for example, in an empty space surrounded by the upper surface 1212 of the damaged part.

[0159] The damaged part 121 can be combined with the cover part 110, whereby the damaged protrusion 124 is located on the upper side of the cover part 110 where the barrier film 114 is located, and can move toward the barrier film 114 as needed, thereby damaging the barrier film 114.

[0160] The thread P1211 for threaded engagement with the connecting portion 116 of the cover portion 110 can be located at the lower part of the first side portion 1211a. Therefore, as described above, the damaged portion 120 can be threadedly engaged with the connecting portion 116 by using the thread P1211.

[0161] The extension length of the second side portion 1211c, which extends downward in parallel with the first side portion 1211a, may be shorter than the extension length of the first side portion 1211a.

[0162] One end of this second side face 1211c can be connected to the end of the upper surface 1211b of the damaged body 121, and the other end can be connected to one side end of the upper surface 1212 of the damaged part.

[0163] Therefore, the damaged protrusion 124 can be connected to the second side portion 1211c of the damaged part body 121 via the upper surface 1212 of the damaged part. In this example, as... Figure 7As shown, the position of the upper surface 1212 of the damaged part changes relative to the second side surface 1211c, moving in the vertical direction. Depending on this vertical positional change, the tilt angle θ1 of the upper surface 1212 of the damaged part changes. For example, in the initial state, the upper surface 1212 of the damaged part may have an inclined surface in an upward direction (first direction) (e.g., + direction) centered on the edge of the damaged part body 121.

[0164] When a physical force is applied to the outer surface of the protruding upper surface 1241 in the initial state, the damaged upper surface 1212 can have a structure that slopes downwards from the edge portion of the damaged upper surface 1212, i.e., the portion connected to the main body side surface 1211. In this case, at least one of the tilt angle θ1 formed by the damaged upper surface 1212 and the setting surface and the shape can be changed from the initial state to the driven state. As an example, the damaged upper surface 1212 has a sloped surface that slopes down in the opposite direction (second direction) (e.g., - direction) from the edge of the connected damaged body 121, so that both the shape and the tilt angle θ1 can be changed from an uphill slope to a downhill slope.

[0165] Based on the vertical positional change of the upper surface 1212 of the damaged part, the damaged protrusion 124 connected to the upper surface 1212 of the damaged part can also move vertically.

[0166] like Figure 2 and Figure 4 As shown, the upper and side portions of the damaged protrusion 124 are respectively sealed by the protruding upper surface 1241 and the protruding side surface 1242, which serve as the upper and side surfaces, respectively, while the lower portion may be open. In this case, the outer side of the protruding upper surface 1241 of the damaged protrusion 124 can be continuously connected to the edge of the damaged upper surface 1212. Thus, the protruding upper surface 1241 and the damaged upper surface 1212, which are connected to each other, can serve as the plug upper surface U100 covering at least a portion of the upper surface of the plug 100.

[0167] At this time, since the protruding length of the downward protruding side 1242, that is, the downward extension length, can vary depending on the position, the surface formed by virtually connecting the lower end of the protruding side 1242 can have a virtual inclined surface that is inclined to either side.

[0168] In addition, the end of the protruding side 1242 of the damaged protrusion 124, that is, the part opposite to the blocking membrane 114, may also have an inclined surface. In this case, the sharpness of the end of the damaged protrusion 124 increases, so the damage action of the blocking membrane 114 located at the bottom can be performed more easily, thereby improving user convenience.

[0169] As described above, the damaged protrusion 124 can move toward the lower side of the barrier membrane 114 side depending on at least one change in the tilt angle θ1 and shape of the damaged body 121.

[0170] At once Figure 2 In other words, the damaged protrusion 124 can move in the downward direction by the change in tilt angle θ1 caused by the change in the state of the upper surface 1212 of the damaged part.

[0171] Furthermore, since the longest protruding part of the damaged protrusion 124, namely the lower part of the barrier membrane 114, is closest to it, the lowermost end EP124 of the part that can be damaged first by the descending action of the damaged protrusion 124, compared with other parts (e.g., the shortest damaged protrusion part P124), can be inclined in a shape that is concave to the outer protruding side on the inner protruding side of the lowermost end EP124 of the damaged protrusion 124, rather than in a straight diagonal line. Figure 2 As shown, the ends of other portions of the damaged protrusion 124 (e.g., the shortest damaged protrusion portion P124) may be obliquely inclined.

[0172] As an example, the end of the lowest end EP124 can be multiple inclined surfaces or curved surfaces with different inclination angles to each other.

[0173] Therefore, the protruding side ends of other parts of the damaged protrusion 122 (e.g., the shortest damaged protrusion part P124) are inclined to a slope, so the thickness will decrease proportionally to the downward side, and the thickness can be predicted. Conversely, the thickness of the lowest end EP124 is disproportionate, so its thickness may not be predictable.

[0174] By utilizing the shape of the lowermost end EP124 of the damage protrusion 124, the damage protrusion 124 can more accurately and quickly damage the barrier membrane 114.

[0175] Therefore, when pressure is applied to the upper surface of the damaged protrusion 124 by the user's action, the damaged protrusion 124 descends downward with respect to the damaged body 121 as the center. Through this descent of the damaged protrusion 124, a portion of the inclined end of the damaged protrusion 124 comes into contact with and penetrates a portion of the adjacent lower blocking membrane 114, thereby damaging a portion of the blocking membrane 114 and the connecting strip 1152 (see reference). Figure 7 ).

[0176] At this time, even when the damaged protrusion 124 is lowered to its lowest height, the part of the damaged protrusion 124 with the shortest protrusion length (i.e., the shortest damaged protrusion part P124) will not come into contact with the blocking membrane 114 corresponding to the lower part. Therefore, the part of the blocking membrane 114 located below the shortest damaged protrusion part P124 and the connecting strip 1152 can still remain connected to the blocking membrane position part 113.

[0177] Since the damaged part 120 is formed as a single unit, all the constituent elements of the damaged part 120 can be made of the same material, such as a plastic material with elasticity.

[0178] In addition, in this example, the thickness of the upper surface 1212 of the damaged part 120 can be thinner than the thickness of other constituent elements (e.g., the damaged part body 121).

[0179] In this case, when pressure is applied to the upper part of the damaged protrusion 124 by means of a finger or the like, the damaged protrusion 124 may have a thickness that allows it to move in the downward direction depending on the applied pressure.

[0180] Due to the thickness of the upper surface 1212 of this damaged part, the user can easily damage the barrier membrane 114 by dropping the damaged protrusion 124 when needed, allowing the secondary contents in the sealed space S100 to fall into the internal space S200 of the container body 200 and mix with the main contents, thereby enabling intake (see reference). Figure 7 ).

[0181] At this time, the maximum descent length of the damaged protrusion 124 can be determined based on at least one of the tilt angle θ1 of the upper surface 1212 of the damaged portion and the width W125 of the upper surface 1212 of the damaged portion, that is, the length between the damaged protrusion 124 and the second side portion.

[0182] In order to take in the contents of the container 1 with this structure, the user can first damage a part of the barrier membrane 114 and a part of the lowering auxiliary part 115 by lowering the damage protrusion 124, so that the secondary contents in the sealed space S100 of the damage part 120 can fall into the internal space S100 of the container body 200.

[0183] In this state, the user can shake container 1 to evenly mix the main contents and secondary contents that are in different states.

[0184] Secondly, the user can unlock the connection 116 with the cover 110 by rotating the damaged part 120 in the corresponding direction. After removing the damaged part 120 from the cover 110, the user can unlock the cover 110 again by rotating the cover 110 connected to the container body 200 in the corresponding direction and expose the injection port 204, so that the main contents and secondary contents mixed together can be taken in.

[0185] Alternatively, by rotating the cap portion 110 attached to the container body 200 in the corresponding direction, the locked state of the cap portion 110 with the damaged portion 120 attached to the upper part is released and the injection port 204 is exposed, so that the main contents and secondary contents inside the container body 200 can be taken in together.

[0186] As described above, by inserting the barrier membrane 114 into and placing it in the barrier membrane position portion 113 through injection molding, the blocking force between the internal space S200 where the main contents are located and the sealed space S100 where the secondary contents are located can be increased, and the phenomenon of barrier membrane 114 detachment can be reduced.

[0187] This greatly reduces the possibility of unnecessary mixing between the main contents and secondary contents during circulation.

[0188] Furthermore, since the barrier film 114 is inserted into and formed in the barrier film position portion 113, the connection structure between the barrier film 114 and the barrier film position portion 113 becomes very simple.

[0189] Furthermore, since the secondary contents can be lowered into the container body 200 to be mixed with the main contents simply by pressing the protrusion 124, the main contents and secondary contents can be easily taken in, thereby greatly improving user convenience.

[0190] Secondly, refer to Figures 8 to 11 The plug 100a according to another embodiment of the present invention will be described.

[0191] Compared to Figures 1 to 7 The plug 100 shown here, for the constituent elements of the plug 100a of this example which have the same structure and perform the same function, are given the same reference numerals as the plug 100, and detailed descriptions thereof are omitted.

[0192] The plug 100a in this example may also have a cap portion 110a and a damage portion 120a.

[0193] The cover portion 110a may include: a cover portion body 111a; a sealing portion 112; a barrier film position portion 113a connected to the cover portion body 111; a barrier film 114 located at the barrier film position portion 113a; a lowering auxiliary portion 115 located above the barrier film 114; and a connecting portion 116 for connecting with the damaged portion 120.

[0194] The main body 111a of the cover portion may also have: a side surface with threads 1111 for engaging with the container body 200; and an upper surface for connecting with the side surface.

[0195] In this example, the outer side of the cover body 111a may have a plurality of longitudinal protrusions 1112, which extend longitudinally and are spaced along the outer peripheral surface of the side.

[0196] Therefore, since this longitudinal protrusion 1112 prevents or reduces sliding motion, the user can more easily perform the rotation of the plug 100.

[0197] Due to the structure of this cover body 111a, the sealing part 112 is located on the inner surface of the upper surface of the cover body 111a and can extend downward, while the connecting part 116 is located on the outer surface of the upper surface and can extend upward.

[0198] However, regarding the upper surface of the cover body 111a in this example, the length extending inward can be shorter compared to the case of the cover body 111.

[0199] Therefore, as Figure 2 As shown, with regard to the plug 100, since at least two of the sealing portion 112, the joint portion 116 and the blocking membrane position portion 113 are in different positions on the upper surface of the cap body 111, the at least two provided portions may not overlap each other.

[0200] However, in the case of the plug 100a in this example, as Figure 11 As shown, on the upper surface of the cover body 111a, the positions of at least two of the sealing portion 112, the joint portion 116, and the barrier film position portion 113a can at least partially overlap. For example, as... Figure 11 As shown, the inner side of the connecting part 116 can be connected to the edge of the barrier film position part 113a.

[0201] As described above, with the reduction in the length of the upper surface of the cover body 111a extending inward, the connection position of the barrier film position portion 113a, which connects to the edge of the upper surface of the cover body 111a, can be moved further outward compared to the case of the cover body 110. Consequently, compared to the case of the cover body 110, the tilt angle θ2 of the barrier film position portion 113a relative to the mounting surface of the container with the stopper 100a (i.e., the tilt angle relative to the mounting surface of the container) can also be reduced.

[0202] The damaged part 120a in this example may also include: a damaged part body 121a, which has a body side 1211a and a damaged part upper surface 1212a; and a damaged protrusion 124a connected to the damaged part body 121a.

[0203] like Figure 11 As shown, with Figure 2 Unlike the main body side 1211, the main body side 1211a of this example may have a side portion extending upward in the height direction, but does not have an upper surface extending in the planar direction.

[0204] Therefore, the upper surface 1212a of the damaged part is directly connected to the side part extending in the height direction, and can exist in the empty space surrounded by the main body side 1211a.

[0205] As described above, since the main body side 1211a of this example does not have a portion extending in the planar direction, one side of the upper surface 1212a of the damaged part can be directly connected to the adjacent main body side 1211a portion.

[0206] The upper surface 1212a of this damaged part can also be a convex surface with a circular planar shape, having a convex shape that protrudes upward, and can move vertically about the connected main body side surface 1211a. In addition, the thickness of the upper surface 1212a of the damaged part can be thinner than the thickness of the main body side surface 1211a.

[0207] like Figure 11 As shown, the damaged protrusion 124a is connected to the edge of the adjacent damaged upper surface 1212a, and can extend in the downward direction on the damaged upper surface 1212a.

[0208] Such a damaged protrusion 124a may include: a protrusion upper surface 1241; a central portion 1243 extending downward from the middle part of the protrusion upper surface 1241; and a plurality of wings 1244 connected to the central portion 1253 and arranged radially at intervals from each other along the outer peripheral surface of the central portion 1243.

[0209] The upper surface 1241 of the protrusion can have a circular planar shape or a flat surface.

[0210] Therefore, the upper part of the damaged portion 120a can be completely covered by the upper surface 1212a of the damaged portion and the upper surface 1241 of the protruding portion 124a. In addition, these upper surfaces 1212a of the damaged portion and the upper surface 1241 of the protruding portion can form the upper surface of the plug having the damaged protrusion 124a and extending downward.

[0211] The central portion 1243 may have a column shape, having a circular cross-sectional shape extending from the middle portion of the inner surface of the protruding upper surface 1241.

[0212] The end of the central portion 1243 may have a side surface with a smaller diameter than other portions, and the lower end may be a flat surface.

[0213] like Figures 9 to 11 As shown, multiple wings 1244 can be arranged outward from the center portion 1243.

[0214] Each wing 1244 can extend for a considerable length along the extension direction of the central portion 1243, and at least two wings 1243 can have different extension lengths.

[0215] At this time, the extension length of each wing 1244 can be shorter than the extension length of the center part 1243.

[0216] like Figures 9 to 11 As shown, each wing 1244 can be a protruding piece that extends outward from the center 1243.

[0217] In the plurality of wings 1244, all wings except the longest wing which is the lowest in height at the very end (e.g., the wing with the longest extension) may have the same shape.

[0218] The number of wings other than the longest wing can be at least one.

[0219] In this example, there are a total of four wings 1244, and each wing except the longest wing can have three wings.

[0220] Multiple wings 1244 can have stepped structures that vary in height depending on their position. For example, such as... Figure 11 As shown, among the multiple wing portions 1244, the height of the end point EP431 of the inner portion adjacent to the center portion 1243 can be higher than the height of the end point EP432 of the outer portion. Therefore, the extension length of the inner portion can be shorter than the extension length of the outer portion.

[0221] Due to the stepped structure of each wing 1244, the inner side adjacent to the center portion 1243 can have an empty space surrounded by the outer portion of each wing 1244. In this case, the longest wing 1244 and the other wing 1244 can differ from each other in shape regarding the connecting surface CP43 between the end EP431 of the inner portion and the outer portion. For example, the connecting surface CP43 of the longest wing 1244 is an inclined surface; conversely, the connecting surface CP43 of the other wing 1244 can be a straight surface (e.g., a vertical surface).

[0222] When a physical force is applied to the upper part of the damaged protrusion 124a due to the multiple wings 1244 having this structure, and the damaged protrusion 124a moves in the downward direction, the central part 1243, which is closest to the barrier membrane 114 among the multiple wings 1244, comes into contact with the middle part of the barrier membrane 114, so that a physical force can be applied to the contacted part.

[0223] Subsequently, due to the continuous descent of the wing 1244, the portion of the blocking membrane 114 opposite the longest wing 1244, that is, an edge portion adjacent to the middle portion of the damaged blocking membrane 114, will be damaged first.

[0224] In this state, due to the continuous descent of the wing 1224, the damaged part can be damaged in sequence around the damaged part via the longest wing 1244. The damaged part that is disconnected from the connecting belt 1152 can be more easily lowered to the lower part by means of the inclined surface CP43 of the longest wing 1244.

[0225] Secondly, refer to Figures 12 to 18 The plug 100b according to another embodiment of the present invention will be described in detail.

[0226] Compared to Figures 1 to 7 The plug 100 shown here, for the components of the plug 100b of this example which have the same structure and perform the same function, are given the same reference numerals as the plug 100, and detailed descriptions thereof are omitted.

[0227] The plug 100b in this example may also have a cap portion 110b and a damage portion 120b.

[0228] The cover portion 110b may include: a cover portion body 111b; a sealing portion 112; a barrier film position portion 113a connected to the cover portion body 111b; a barrier film 114 located at the barrier film position portion 113a; a lowering auxiliary portion 115b located above the barrier film 114; and a connecting portion 116 for connecting with the damaged portion 120b.

[0229] The main body 111b of the cover portion may have: a side surface having threads 111 for engaging with the container body 200; and an upper surface for connecting with the side surface.

[0230] Due to the structure of this cover body 111b, the sealing part 112 and the connecting part 116 can be located on the inner and outer surfaces of the upper surface of the cover body 111b, respectively.

[0231] However, regarding the upper surface of the cover body 111a in this example, the length extending inward can be shorter compared to the case of the cover body 111.

[0232] Therefore, as Figure 2 As shown, since at least two of the sealing portion 112, the joint portion 116, and the barrier film position portion 113 are located at different positions on the upper surface of the cover body 111, the portions at at least two positions may not overlap each other.

[0233] However, for the purposes of this example, as Figure 15 As shown, on the upper surface of the cover body 111a, the positions of at least two of the sealing portion 112, the joint portion 116, and the barrier film position portion 113a can at least partially overlap. As an example, such as... Figure 15 As shown, the inner side of the joint 116 can be connected to the edge of the barrier film position portion 113a.

[0234] As described above, with the reduction in the length of the upper surface of the cover body 111a extending inward, the connection position of the barrier film position portion 113a, which is connected to the edge of the upper surface of the cover body 111a, can be moved further outward compared to the case of the cover body 110. Consequently, the inclination angle θ2 of the barrier film position portion 113a relative to the mounting surface of the container with the stopper 100b can also be reduced compared to the case of the cover body 110.

[0235] The damaged part 120b in this example may also include: a damaged part body 121b, which has a body side 1211a and a damaged part upper surface 1212b; and a damaged protrusion 124b, which is connected to the barrier membrane damaged body 121b.

[0236] like Figure 15 As shown, with Figure 2 Unlike the main body side 1211, the main body side 1211a of this example may have a side portion extending upward in the height direction, but does not have an upper portion extending in the planar direction.

[0237] Therefore, the upper surface 1212b of the damaged part is directly connected to the main body side 1211a extending along the height direction, and there can be an empty space surrounded by the main body side 1211a.

[0238] As described above, since the main body side surface 1211a does not have a portion extending in the planar direction, one side of the upper surface 1212b of the damaged portion can be directly connected to the adjacent main body side surface 1211a portion.

[0239] The upper surface 1212b of this damaged part can also be a convex surface with a circular planar shape, having an upwardly projecting convex shape, and can move downward about the connected main body side surface 1211a. In addition, the thickness of the upper surface 1212a of the damaged part can be thinner than the thickness of the main body side surface 1211a.

[0240] like Figure 15 As shown, the upper surface 1212b of the damaged part in this example may include: a first part 1212b1, which is directly connected to the main body side 1211a and is inclined downward from the corresponding part of the main body side 1211a; and a second part 1212b2, which is continuously connected between the first part 1212b1 and the damaged protrusion 124b and is inclined from the first part 1212b1 toward the damaged protrusion 124b.

[0241] Due to the first part 1212b1 and the second part 1212b2, the upper surface 1212b of the damaged part can have a shape that extends downward from the side surface 1211a of the main body and then bends, and extends upward.

[0242] Therefore, the damaged protrusion 124b can move vertically around the recess that serves as the junction of the first part 1212b1 and the second part 1212b2.

[0243] like Figure 15 As shown, the damaged protrusion 124b is connected to the upper surface 1212b of the damaged portion, specifically to the second portion 1212b2 located at the edge of the adjacent upper surface 1212b of the damaged portion, and can extend from the upper surface 1212b of the damaged portion in the downward direction.

[0244] like Figure 14 As shown, such a damaged protrusion 124b may include: a protrusion upper surface 1241; a central portion 1243 extending downward from the middle portion of the protrusion upper surface 1241; and a plurality of wings 1244b connected to the central portion 1243 and arranged radially at intervals from each other along the outer peripheral surface of the central portion 1243.

[0245] The upper surface 1241 of the protrusion can have a circular planar shape or a flat surface.

[0246] Therefore, the first part 1212b1, the second part 1212b2 and the protruding upper surface 1241 of the damaged part also cover the upper part of the damaged part 120b, which can constitute the upper surface of the plug as the upper surface of the cover part 200.

[0247] However, this stopper surface is not limited to this; other shapes of upper surfaces that can move the damaged protrusion 124b downward by force applied externally, such as the stopper surface, are also possible.

[0248] The central portion 1243 may have a column shape, having a circular cross-sectional shape extending from the middle portion of the inner surface of the protruding upper surface 1241.

[0249] like Figure 13 and Figure 14 As shown, multiple wings 1244b can be arranged outward from the center portion 1243, can extend for a long time along the extension direction of the center portion 1243, and can have the same length and shape.

[0250] Each wing 1244b can be a protrusion extending outward from the center portion 1243. Therefore, at the same height, the protrusion height outward of each wing 1244b can be the same.

[0251] At this time, the end of each wing 1244b may have an inclined surface with a curved surface that is inclined upward with the center portion 1243 as the center, and the damaged protrusion 124b in this example may have an arrow shape.

[0252] Because of the multiple wings 1244b with this structure, when physical force is applied to the upper part of the damaged protrusion 124b, and the damaged protrusion 124b moves in the downward direction, among the multiple wings 1244b, the central part 1243 most adjacent to the barrier membrane 114 is damaged first, and the exposed area EP114 located in the middle part of the barrier membrane 114 is damaged. Through the continuous downward movement of the damaged protrusion 124b, the exposed area EP114 located between the corresponding parts of the barrier membrane 114 (e.g., the downward auxiliary part 115b) with the middle part EP114 of the damaged barrier membrane 114 as the starting point will be damaged.

[0253] The descent aid 115b located on the barrier membrane 114 also makes it easier for the damaged barrier membrane 114 to move into the interior of the container body 200 by adding weight to the damaged barrier membrane 114.

[0254] Therefore, as Figure 16a and Figure 16bAs shown, the lowering auxiliary part 115b of this example may include: a plurality of auxiliary part bodies 1151b, which are disposed at intervals on the barrier membrane 114; and a plurality of connecting strips 1152, which are located at the edge of each auxiliary part body 1151b and connect each auxiliary part body 1151b to the cover body body 111a.

[0255] Therefore, as Figure 16a As shown, since multiple auxiliary body parts 1152b are spaced apart on the barrier membrane 114, and... Figure 6a and Figure 6b Unlike other examples, the descending auxiliary part 115b in this example may have a partially exposed barrier membrane area EA115 between two adjacent auxiliary part bodies 1152b.

[0256] The auxiliary part body 1151b and the connecting strip 1152 are made of the same material as each other, and the auxiliary part body 1151b and the connecting strip 1152 may also be made of the same material as the adjacent barrier membrane position part 113a.

[0257] like Figure 16a As shown, each auxiliary part body 1152b may have a fan-shaped planar shape.

[0258] As described above, when the descent auxiliary section 115b is divided into multiple auxiliary section bodies 1152b, the correspondence between each wing 1244b of the damaged protrusion 124b corresponding to the descent auxiliary section 115b can be as follows: Figure 17 and Figure 18 As shown.

[0259] First, such as Figure 17 As shown, as an example, each wing 1244b of the damaged protrusion 124b can be configured to face the barrier membrane exposure area EA115, which is located between adjacent auxiliary body 1151b.

[0260] In this case, after each wing 1244b of the damaged protrusion 124b comes into contact with the corresponding barrier membrane exposure area EA115, the contacted barrier membrane exposure area EA115 can be damaged.

[0261] At this time, the barrier membrane 114 can perform a damage action from the middle part corresponding to the center part 1243 to the edge side, and the corresponding auxiliary part body 1151b can be located on each damaged barrier membrane part.

[0262] Therefore, by means of the auxiliary body 1151b located in each damaged barrier membrane section, the descent action of the damaged barrier membrane section can be performed more quickly and easily, and the opening speed of the injection port blocked by the barrier membrane 114 can be increased.

[0263] In addition, since the edge of the auxiliary part body 1151b located on the damaged barrier membrane part is connected to the barrier membrane position part 113a via the connecting strip 1152, the damaged barrier membrane part moves towards the container body 200 more quickly, thereby increasing the opening area of ​​the injection port.

[0264] Secondly, refer to Figure 18 Further examples of the correspondence between each wing 1244b of the descent aid 115b and the damage protrusion 124b are illustrated.

[0265] and Figure 17 The difference lies in Figure 18 In the example, each wing 1244b can be located at a position corresponding to the auxiliary body 1151b, rather than the exposed barrier membrane exposure area EA115. Therefore, with Figure 17 In contrast to the case in the previous example, each wing 1244b can be positioned on the upper surface 1241 of the protrusion with a rotation of approximately 60 degrees.

[0266] Thus, each wing 1244b of the descending damaged protrusion 124b can apply force to the corresponding auxiliary body 1151b after it comes into contact with the adjacent auxiliary body 1151b.

[0267] Therefore, the barrier membrane 114 can be damaged with the exposed area EA115 as the center. Since the exposed area EA115 lacks the auxiliary body 1151b, its strength is relatively weaker than the barrier membrane portion with the auxiliary body 1151b. Even so, because the exposed area EA115 of the barrier membrane 114 opposite the center 1243 is damaged first, the barrier membrane 114 is damaged from its center to its edge, and the barrier membrane 114 can be divided into multiple damaged barrier membrane portions.

[0268] Even under these circumstances, the lowering action of the damaged barrier membrane portion can be performed more quickly and easily by means of the auxiliary body 1151b located in each damaged barrier membrane portion, thereby increasing the open area of ​​the injection port.

[0269] The following is for reference Figures 19 to 22 Another embodiment of the present invention will be described below. For ease of explanation, reference will be made to the following. Figures 19 to 22 The embodiments described herein focus on the differences from the embodiments described above.

[0270] Figure 19 This is a cover portion illustrating yet another embodiment of the present invention. Figure 20 The barrier film is shown to be bonded to the cover portion in another embodiment of the present invention.

[0271] Reference Figure 19 and Figure 20 The cover portion 100 includes a cover portion body 111c, a barrier film position portion 113c, and a barrier film 114. In particular, the barrier film position portion 113c includes a joint portion 190 and a groove portion 195.

[0272] The joining portion 190 is the part that joins with the barrier film 114. Specifically, the joining portion 190 includes an attachment surface 191 facing upwards and engaging with the joining surface. The attachment surface 191 is formed as an annular surface facing upwards and is attached to and engaged with the lower surface of the barrier film 114. The joining portion 190 is formed in a shape that protrudes relative to the outer groove portion 195, and the attachment surface 191 may correspond to the upper surface of the protruding joining portion 190.

[0273] Here, the attachment surface 191 can be formed as a flat surface, but depending on the situation, it can be formed as an inclined surface, causing it to descend in the central direction (e.g., the central direction of the barrier film 114). As described above, when the attachment surface 191 is formed as an inclined surface, the contents slide and accumulate in the central direction, thereby allowing them to easily enter the interior of the container.

[0274] The groove 195 is formed around the outer side of the joint 190 and is the part that separates the joint 190 from the main body 111c of the cover portion. The groove 195 can be covered by the outer extension surface 114c corresponding to the outermost side of the barrier membrane 114.

[0275] The outer extension surface 114c may extend beyond the groove 195 and further outward. Specifically, the outer extension surface 114c may be formed as an inclined surface extending to the cover portion 110 to cover the inclined surface of the cover portion 110.

[0276] Reference Figure 15 The inclined surface of the cover portion 110 will be described below. The inclined surface of the cover portion 110 refers to the inclined surface formed on the outer side of the joint portion 190, sloping downwards towards the center of the barrier film 114. It is related to... Figure 15 The part shown in the middle corresponds to the structure 113a.

[0277] The lower surface of the barrier film 114 is attached to and bonded to the attachment surface 191 of the bonding portion 190. If the portion of the barrier film 114 that is attached to and bonded to the attachment surface 191 is referred to as the bonding surface 114b, then the barrier film 114 may also include a central surface 114a and an outer extension surface 114c based on the bonding surface 114b.

[0278] Specifically, the barrier film 114 may include: a bonding surface 114b, which bonds to the bonding portion 190; a central surface 114a, forming the inner side of the bonding surface 114b; and an outer extending surface 114c, extending outward from the bonding surface 114b. According to the above structure, the outer extending surface 114c of the barrier film 114 is located outside the container body 200, rather than the container body 200 containing beverages, etc. When the uncoated portion of the outer edge of the barrier film 114 comes into contact with beverages, corrosion and other problems may occur. Figure 19 and Figure 20 The structure shown has the outer edge of the barrier membrane 114 located outside the container body 200 rather than within the container body 200, thus having the advantage of not coming into direct contact with beverages and preventing corrosion and other problems.

[0279] Figure 21 The cover portion of another embodiment of the present invention is shown. Figure 22 The barrier film is shown to be bonded to the cover portion in another embodiment of the present invention.

[0280] Reference Figure 21 and Figure 22 The cover portion 110 may further include a descent assist portion 115c located below the barrier film 114 and assisting in the descent of the barrier film. The descent assist portion 115c includes: at least one assist portion body 1151c located at a position in contact with the barrier film 114; and a connecting strap 1152 disposed at predetermined intervals along the edge portion of the at least one assist portion body 1151c, connecting the at least one assist portion body 1151c to the cover portion body 111c or the barrier film position portion 113c. At least a portion of the assist portion body 1151c is coupled to the lower surface of the barrier film 114 and can descend downwards together with the barrier film 114.

[0281] The technical features disclosed in each embodiment of the present invention are not limited to that embodiment. Unless they are incompatible with each other, the technical features disclosed in each embodiment can be combined and applied to other different embodiments.

[0282] Therefore, in each embodiment, the description focuses on the individual technical features, but unless each technical feature is incompatible with the others, they can be combined and applied together.

[0283] This invention is not limited to the embodiments and accompanying drawings described above, and various modifications and variations can be made from the viewpoint of those skilled in the art. Therefore, the scope of this invention is determined not only by the scope of the claims in this specification, but also by those equivalent to those claims.
