Description

Technical Field

[0001] This utility model relates to a bag. Background Technology

[0002] Since the beginning, it has become increasingly common in various stores, such as convenience stores and fast food restaurants, to serve beverages and food in simple containers or wrapped in paper. Furthermore, in recent years, convenience stores have seen a surge in customers purchasing beverages such as coffee in pre-packaged containers. Moreover, in fast food restaurants and similar establishments, in addition to dine-in customers, there is a significant increase in customers opting for takeout services (such as picking up goods and eating them elsewhere) and delivery services (such as having goods delivered to pre-designated locations).

[0003] Typically, when customers accept takeout or delivery services, goods are usually provided in a bag. Bags have existed in various forms throughout history. For example, bags commonly made of paper are frequently used. These bags generally have a storage space enclosed by the bottom and sides, used to store goods (hereinafter, the items stored in the storage space are sometimes referred to as "contents") (e.g., Patent Documents 1 and 2). In the aforementioned types of stores, the practice of providing goods purchased by customers in bags is widespread. However, when using the bags disclosed in Patent Documents 1 and 2, there are concerns that store clerks might carelessly store goods in the bag's storage space before serving them to customers. In such cases, especially if the container stored in the bag is in a state where it is easily tipped over, there is a concern that beverages might spill out of the container before the customer can eat or drink. To address this issue, the following approach is being taken: a cup holder, as disclosed in Patent Document 3, is stored in the bag, and the goods are provided to the customer while the container is held in place by the cup holder.

[0004] Existing technical documents

[0005] Patent documents

[0006] Patent Document 1: Japanese Utility Model Registration No. 3128559

[0007] Patent Document 2: Japanese Patent Application Publication No. 2022-056066

[0008] Patent Document 3: Japanese Patent Application Publication No. 2019-038596 Utility Model Content

[0009] The cup holder disclosed in Patent Document 3 has an opening for holding the container, thus holding the container by inserting its lower part into the cup holder from above. However, in busy shops, there is a concern that the container containing the beverage may not be securely inserted into the cup holder before being served to the customer. Therefore, even using the cup holder disclosed in Patent Document 3, it is difficult to reliably solve the risk of the container tipping over inside the bag. In addition, the cup holder is usually formed independently of the bag. Therefore, when serving beverages to customers, not only is it necessary to store the container into the bag, but there is also an additional step of storing the cup holder into the bag before the container, which is a concern as it may become very time-consuming and cumbersome.

[0010] Furthermore, even when the container is held in place by a cup holder inside the bag, there are concerns about the container easily falling off the cup holder due to shaking during customer takeout and delivery by staff. There are also concerns that the beverage might spill out of the container due to shaking while held in place. Typically, when a container is placed inside a bag, it is sealed by fitting the lid against the circumference of the container. However, this does not completely eliminate the risk of leakage from gaps created between the container and the lid due to shaking.

[0011] Furthermore, the cup holder disclosed in Patent Document 3 needs to have the strength to hold the container inserted into the opening as long as possible. Therefore, it mostly uses thick paper with toughness, corrugated paper, and molded bodies based on pulp molding technology. In addition, cup holders are mostly three-dimensional in order to hold the container, but storage needs to be considered during distribution and in-store storage, so they need to be in a somewhat flat form. Therefore, cup holders need to be able to deform from a flat shape to a three-dimensional shape with a simple operation. As mentioned above, cup holders are usually made of strong paper materials such as thick paper. Therefore, in order to deform from a flat shape to a three-dimensional shape with a simple operation, creases or seams need to be formed in advance at the deformation points. However, if such creases are formed, there is a concern that if the beverage leaks from the container, the leaked beverage may wet the bag through the creases of the cup holder.

[0012] This invention was made in view of the following problems, and its purpose is to provide a bag that can easily and stably hold a container in place through simple operation, and can significantly reduce the bag from getting wet from the liquid even if the beverage leaks from the container.

[0393] The present invention will be described as an example of a bag used to contain beverages and food. However, the use of the bag is not limited to containing beverages and food; it can also be used to contain items other than beverages and food. The types of beverages and food contained in the bag of the present invention are not limited, including beverages contained in cups such as coffee and carbonated drinks, food contained in containers of a specified size and shape such as French fries, and various types of food such as hamburgers wrapped in packaging paper.

[0394] Furthermore, the following example illustrates a situation where the contents defined as items stored inside the bag are containers (cups) containing beverages, and containers of a predetermined size and shape containing food.

[0395] In this specification and accompanying drawings, even if the embodiments are different, the same reference numerals are used for configurations that have substantially the same features, and detailed descriptions of such configurations are omitted.

[0396] The following description represents preferred embodiments of this utility model, but the scope of this utility model is not limited to these embodiments. Furthermore, in the following description, directions such as front-back, left-right, up-down, and horizontal plane are used for ease of explanation, but the scope of this utility model is not limited to these directions. Figure 1In this example, the Z-axis direction is taken as the up-down direction (the upper side is the +Z direction, and the lower side is the -Z direction). The directions of the X-axis and Y-axis, which are orthogonal to each other and lie on a plane with the Z-axis as the normal, are defined as the X-axis direction and Y-axis direction, respectively. Furthermore, the plane defined by the X-axis and Y-axis, i.e., the XY plane, is a horizontal plane. This explanation is based on these concepts. Regarding the X-axis, Y-axis, and Z-axis, in... Figure 1 Other attached figures ( Figures 2 to 77 The same applies to (the ). Figures 1 to 77 The relative size ratios shown in the figures are for convenience and do not represent actual size ratios.

[0397] [1 First Embodiment]

[0398] [1-1 Composition]

[0399] The bag 10 of the first embodiment has a main body 20, which forms a container capable of holding contents ( Figure 2 , Figure 3 The container 200 has a space 23 for housing and an opening 24 for inserting the container 200 (contents) into the housing space (space 23).

[0400] (main body)

[0401] The main body 20 has a bottom 22 and a peripheral wall portion 21 that is continuous with the bottom at its periphery. In the main body, a receiving space (hereinafter referred to as space portion 23) is formed as the space enclosed by the peripheral wall portion that is continuous with the bottom at its periphery.

[0402] (Material of the main body)

[0403] The material of the main body 20 is not particularly limited, but from the viewpoints of hygroscopicity and environmental burden reduction, it is preferred to be formed of paper-like materials with fibers. Figure 1 A to Figure 1In example C, the main body 20 is formed of paper-based materials. Besides paper made by bonding plant fibers and other fibers, examples of paper-based materials include chemical fiber paper, synthetic paper, water-resistant paper, coated paper, substitute paper, parchment, wool paper, fiberglass paper, stone paper, and ceramic paper. Paper-based materials can be recycled or non-recycled paper. Furthermore, as long as the main body 20 contains paper-based materials, the use of non-paper-based materials is not prohibited. Examples of non-paper-based materials include fabric materials (woven materials and non-woven materials). Examples of non-woven materials include air-laid sheets (formed from open-fiber raw materials that have been stacked by airflow), pulp-based materials, natural fiber materials, and synthetic fibers. Materials combining paper-based and non-paper-based materials can also be used as the material of the main body 20. Non-paper-based materials can be resins composed of resin materials such as synthetic resins and natural resins. As an example of combining paper materials and resin, one could exemplify a case where the body 20 has a structure in which a resin sheet is laminated on at least one surface of the paper material. However, as described above, from the viewpoint of reducing environmental burden, it is preferable to omit the resin sheet (consisting only of paper material) regarding the material of the body 20.

[0404] When the main body 20 is composed of a sheet of paper-like material, the sheet of paper-like material forming the main body 20 preferably has water-resistant properties. For example, in the manufacturing process of such a sheet of paper-like material (for example, in the case of specifically performing a papermaking process using raw material fibers (such as pulp fibers), various additives such as lubricating strength enhancers, sizing agents (e.g., alkyl ketene dimers (AKD)), and cationic starch are added to the raw material fibers of the sheet in a prescribed amount. As additives, in addition to lubricating strength enhancers and sizing agents, calcium carbonate can also be used. In this case, various additives such as lubricating strength enhancers, sizing agents, cationic starch, and calcium carbonate can be added to the raw material fibers of the sheet. At this time, the amount of these additives is set to an amount that can improve the degree of water resistance. Thus, a sheet with improved water resistance can be obtained as a sheet of paper-like material. The additives described above are one example; other substances can also be added, or other substances with functions equivalent to those of the additives described above can be used.

[0405] When the main body 20 is made of a sheet of paper material, the main body 20 can be a main body on which a layer for improving waterproofing is formed on the surface of the sheet of paper material by means of a coating method or the like.

[0406] (Zhoubi section)

[0407] The peripheral wall portion 21 rises from the periphery of the bottom portion 22. Furthermore, the peripheral wall portion is continuous with the bottom portion at its periphery. Figure 1In the example, the peripheral wall portion 21 is continuously formed from the periphery of the bottom portion 22. The peripheral wall portion is cylindrical, and the space enclosed by the bottom portion and the peripheral wall portion (described later) forms a spatial portion. "A peripheral wall portion that is continuous with the bottom periphery" means that the peripheral wall portion is continuous at the periphery of the bottom in the state of the bag body. The cases in which the peripheral wall portion is continuous at the periphery of the bottom include the case where the bottom and the peripheral wall portion are formed by bending a single blank (the case where the peripheral wall portion is continuously formed at the periphery of the bottom), and the case where the bottom and the peripheral wall portion are formed by joining different blanks. That is to say, "a peripheral wall portion that is continuous at the periphery of the bottom" means that a structure is formed in which the bottom and the peripheral wall portion are connected.

[0408] Figure 1 In this example, the peripheral wall portion has a set of facing wall surfaces 25 (main wall surfaces) and a set of facing side wall surfaces 26. In the peripheral wall portion, each wall surface is connected to the side wall surface at its side edge.

[0409] (bottom)

[0410] The bottom 22 forms the bottom surface of the main body 20. The structure of the bottom 22 is not particularly limited as long as it can prevent the contents stored in the space from falling downwards. Figure 1 In the example, as well as Figure 5 A to Figure 5 As shown in Figure C, the bottom is formed as a portion with a folding structure 27, which is formed by folding the portion of the blank 500 corresponding to the bottom 22 (bottom corresponding portion 501). Furthermore, Figure 5 Figure A is a diagram illustrating the bending of blank 500 when a folded structure is formed. Additionally, Figure 5 B Figure 5 The example of C is an example of bottom 22, but it does not limit the construction of bottom 22.

[0411] (Corner)

[0412] The main body may have at least one corner portion 28. The corner portion 28 is formed on the inner surface 21A of the peripheral wall portion 21. Figure 1 In the example, corner 28 is formed such that it extends from the bottom toward the opening. Corner 28 is located at the boundary between the wall surface and the side wall surface.

[0413] (Main Lining Section)

[0414] Preferably, in the main body 20, when a set of wall surfaces 25 are designated as a first wall surface 25A and a second wall surface 25B, a main body lining portion 29 is formed on the set of side wall surfaces 26 to change the distance between the first wall surface and the second wall surface. In this case, when the bag body 10 is not in use, the shape of the main body lining portion can be such that the distance between the first wall surface and the second wall surface is small (referred to as the shrinking state). Furthermore, when the bag body is in use, the shape of the main body lining portion can be such that the distance between the first wall surface and the second wall surface is large (referred to as the widening state). In this way, the bag body can be set to the widening state and the shrinking state as needed, thereby allowing storage even in narrow places when not in use, and ensuring sufficient space for storing contents when in use.

[0415] (Position limiting component)

[0416] The main body is provided with a position limiting component 30. The position limiting component 30 may be a single component, or it may be as follows: Figure 6 As shown in A, there are multiple locations. Figure 6 In example A, there are two independent position limiting members 30, which can change between a first shape state ST1 and a second shape state ST2 (movement of the movable part of the limiting wall 31 in the direction of arrow T) with respect to the state of the limiting wall 31. Figure 6 For ease of explanation, details regarding the thickness of each component and the main body lining 29 have been omitted. This is relevant to... Figure 4 , Figure 7 The same applies.

[0417] The position limiting component 30 engages at least with the inner surface of the peripheral wall portion. Figure 1 , Figure 2 In the example of the above, a joining allowance portion 32 is formed in the side end of the limiting wall portion 31, which is joined to the peripheral wall portion 21, and the joining allowance portion 32 is joined to the inner surface of the peripheral wall portion. Figure 1 , Figure 2 This example is one way to avoid the formation of the joining allowance 32. For example, as well as... Figure 11 As shown in B, the position limiting member 30 can also be formed in the shape described later in the second embodiment, where the clamped wall 50 and the limiting wall are connected in a ring shape, and the clamped wall 50 is joined to the inner surface of the peripheral wall. Additionally, as... Figure 1 , Figure 2As shown, when the peripheral wall portion has a wall surface portion 25 and a side wall surface portion 26, the position limiting member 30 is preferably engaged with the wall surface portion and the side wall surface portion. In this case, when the corner portion 28 is formed at the boundary position between the wall surface portion and the side wall surface portion, when the limiting wall portion 31 is in the second shape state ST2, the position limiting member 30 covers at least a portion of the corner portion 28, thereby ensuring that the limiting wall portion of the position limiting member is in the state described above. Figure 2 As shown in Figure A, after transforming from the second shape state ST2 to the first shape state ST1, it is difficult to return from the first shape state ST1 to the second shape state ST2. Similar to the joining allowance portion 32, the portion of the limiting wall that engages with other components and parts is called the fixed portion, and the portion of the limiting wall other than the fixed portion is called the movable portion. The movable portion can move between a position close to the fixed portion (first position) and a position a predetermined distance away from the fixed portion (second position). The more the movable portion moves away from the fixed portion to the second position (second position), the easier it is to form the first shape state, allowing the small space portion 33, described later, to be sized to accommodate containers (paper cups, French fry containers, etc.).

[0418] (Restricted wall portion)

[0419] The position limiting member 30 has a limiting wall. The limiting wall limits the movement of the contents inside the space 23 (more preferably, the horizontal movement of the contents inside the small space 33).

[0420] In the position limiting member 30, the limiting wall portion 31 is configured to form at least a first shape state ST1, in which the opposing surface 34 forms a concave surface, and a second shape state ST2, which is different from the first shape state. The opposing surface 34 is defined as follows. That is, when the contents ( Figure 2 B Figure 3 When container 200 (e.g., in type B) is placed in the space 23, the surface of the limiting wall 31 that faces the contents is called the opposing surface 34. Placing the contents in the space in a manner where movement is restricted by the limiting wall means that, when the bag body 10 is configured such that the bottom faces downwards and the opening faces upwards, the horizontal movement of the contents placed in the space is restricted. Furthermore, this state of movement restriction by the limiting wall is achieved by forming a second shape state ST2 in the limiting wall when the contents are placed in the space.

[0421] The size of the limiting wall can be determined according to the size of the contents. For example, if the contents are a container 200 with a container body for holding beverages, the size of the limiting wall can be determined according to the outer diameter and outer shape of the container body 210.

[0422] Furthermore, the limiting wall is preferably formed near the upper end of the container body. This arrangement facilitates contact between the limiting wall and the outer periphery of the container, for example, when the container holding the beverage is held by the small space 33. This allows the limiting wall to function as a cup sleeve, easily achieving heat insulation and improving the container's heat retention or cold retention, thus maintaining the beverage temperature at a comfortable level for an extended period. Furthermore, when the container 200 is positioned in the small space 33, in... Figure 3 In the example shown in B, the container 200 is configured such that the container body 210 directly faces the limiting wall 31. This is an example, as... Figure 52 As shown in Figure A, a cup sleeve 41 is fitted onto the outer periphery of the container body 210 of the container 200. When the container 200 is stored in the bag body 10, as... Figure 52 As shown in Figure B, the container 200 with the cup sleeve 41 can be placed in the small space 33. By storing the container 200 in this way, the container's heat retention or cold retention is improved, and the temperature of the beverage inside the container can be maintained at a good temperature for a longer period of time. Furthermore, Figure 52 The cup sleeve 41 shown in A is formed into a cylindrical shape that conforms to the shape of the outer peripheral surface of the container body 210, but this is an example and the cup sleeve 41 is not limited to this shape.

[0423] (Positional relationship between the corner and the limiting wall)

[0424] In addition, such as Figure 1 As shown in example A, when the main body has a corner portion 28, it is preferable that when the limiting wall portion 31 is in the second shape state ST2, the position limiting member 30 covers at least a portion of at least one of the corner portions. In this case, a small space portion 33 can be formed in the position of the main body including the corner portion. In addition, in this case, when the movable part moves from the first position to the second position, the small space portion formed in the state surrounded by the fixed part and the movable part can be made large, and a state that can easily hold a relatively large contents can be formed.

[0425] (First shape state and second shape state)

[0426] Regarding the state of the restricted wall portion, there are no particular limitations as long as the first shape state ST1 is such that the opposing surface 34 forms a concave surface, but... Figure 2 In example A, the concave surface becomes a V-shaped (V-shaped cross-section) surface. Figure 2Example A is one example; the concave surface can also be a U-shaped surface. For the first shape state ST1, in the state where the opposing surface 34 forms a concave surface, this includes the case where the entire area of ​​the opposing surface 34 is concave, and also the case where a portion of the opposing surface 34 is concave. However, from the viewpoint of ensuring a small space portion 33 with sufficient size, the first shape state ST1 is preferably the case where approximately the entire area of ​​the opposing surface 34 (the area of ​​the opposing surface 34 corresponding to the aforementioned movable portion) is concave. Furthermore, regarding whether the opposing surface 34 is in the state where it forms a concave surface, it can be determined by selecting two different points of the opposing surface 34, using a straight line passing through these two points as a reference (reference line ML), and confirming whether the opposing surface 34 exists in the portion on the side away from the peripheral wall portion 21 compared to the reference line ML when viewed from above the bag body 10. If the opposing surface 34 exists in the portion on the side away from the peripheral wall portion 21 compared to the reference line, it can be determined that the "part located on the side away from the peripheral wall portion 21" of the opposing surface 34 forms a concave surface.

[0427] Regarding the state of the limiting wall portion, the second shape state ST2 is not particularly limited as long as it differs from the first shape state ST1. For example, the second shape state ST2 can be exemplified by the state in which the opposing surface 34 forms a convex surface. As an example of the state in which the opposing surface 34 forms a convex surface... Figure 1 As shown in example A, examples can be given of surfaces where a convex surface becomes mountain-shaped (with a mountain-shaped cross-section). Furthermore, Figure 1 Example A is one example; the convex surface can also be a surface resembling the outer surface of a column, a spherical surface, etc. Furthermore, the second shape state ST2 is preferably a state in which a convex surface is formed on the opposing surface such that the limiting wall portion follows the inner surface 21A of the peripheral wall portion 21. When the limiting wall portion is configured to cover the corner portion, the second shape state can be defined as a state in which the shape of the opposing surface in the limiting wall portion is a convex shape corresponding to the shape of the inner surface side of the corner portion. Additionally, in the concept that the second shape state ST2 is a state different from the first shape state ST1, it includes a state in which the opposing surface 34 is a flat surface.

[0428] (Material of the position-limiting component)

[0429] The material of the position limiting member 30 is not particularly limited. The material of the position limiting member can be paper, resin, or metal. From the perspectives of ease of handling and environmental reduction, the position limiting member is preferably made of paper. Furthermore, the position limiting member is preferably waterproof. Therefore, it is more preferable that the position limiting member is made of paper and is waterproof. When the contents contained within the bag are a container holding liquid, even if the liquid contained in the container adheres to the position limiting member, it is unlikely that the position limiting member will absorb the liquid and thus reduce its strength.

[0430] (The positional relationship between the contents and the position limiting components)

[0431] When the bag is not in use, the position limiting member located on the inner surface of the bag body allows the limiting wall to be in a second shape. When the bag is in use, for example, the user touches the limiting wall and changes it from the second shape to the first shape. The contents are then inserted into the space of the bag so that the contents face the opposing surface. For example, if the contents are a container holding liquid, the container is inserted into the space from the opening of the bag so that the outer peripheral surface of the container body faces the opposing surface.

[0432] (Small Space Department)

[0433] Furthermore, in this specification, the "space portion enclosed by the main body and the position limiting member" and the "space portion in which the limiting wall is set to a first shape and is designed for insertion of the container so that the container faces the opposite side" in the space portion 23 of the bag body are referred to as the small space portion 33. Moreover, the portion forming the small space portion (the portion of the limiting wall and the portion of the peripheral wall) can function as a holding portion for restricting the movement of the contents such as the container and holding the contents. Thus, according to this utility model, the portion of the peripheral wall can function as a means of restricting the movement of the contents.

[0434] As described above, when the container, which will become the contents, is placed in the space, it is preferable that at least a portion of the upper end of the limiting wall exists between it and the outer peripheral surface of the container. By having a gap between at least a portion of the upper end of the limiting wall and the outer peripheral surface of the container, even if liquid or the like splashes from the container, the splashed liquid can collide with the limiting wall, making it difficult for liquid to splash outwards from the limiting wall. Therefore, when the bag contains items other than the container, it is possible to suppress the occurrence of liquid spilling onto the upper surface of the items other than the container.

[0435] (Surface condition of the position limiting component)

[0436] The position limiting component can be in a smooth state with no surface roughening, or it can have a rough, embossed surface. By using a rough, embossed surface on the position limiting component, it is easier to achieve a higher thermal insulation effect.

[0437] (Burnt material)

[0438] Figure 1 In the example of bag A, as shown, Figure 4 , Figure 5 As shown, the main body 20 is formed from a blank 500. Figure 4 , Figure 5 This is a diagram illustrating the manufacturing process of the bag body 10. (For example...) Figure 4 As shown in A, the blank 500 can be determined according to the shape and manufacturing method of the main body 20. For example, if the main body 20 is a sheet with paper material and waterproof properties, the sheet forming the blank 500 can be a sheet obtained by papermaking of a raw material including paper material (or composed of paper material) with various of the above-mentioned additives (wet strength enhancer, AKD, calcium carbonate and cationic starch, etc. (the additives described in this specification may be added to the raw material fibers in all kinds or only some kinds of additives depending on the use and function)). Figure 4 In the example shown, the blank 500 is composed of a rectangular sheet. When manufacturing the bag body 10, the position limiting member 30 is placed as follows: Figure 4 As shown by B, it is positioned at the specified location on the billet 500. For example... Figure 4 As shown in C, the rectangular blank 500 is positioned corresponding to the corner 28. Figure 4 The blank 500 is bent in the direction of arrow F1 at the middle position (PU), so that the bonding allowance at the side end of the blank 500 is bonded (the bonded portion formed at this time is called the blank bonding portion 551). At this time, a cylindrical structure 530 is formed. The blank has a portion corresponding to the peripheral wall (peripheral wall corresponding portion 502) and a portion corresponding to the bottom (bottom corresponding portion 501) predetermined, such as Figure 5 As shown in A, the portion of the cylindrical structure corresponding to the bottom (bottom corresponding part 501) is bent inward. Figure 5In example A, the downward-extending portion (part 501A) of the bottom corresponding part 501 corresponding to the side wall surface is folded in the inward direction (the central direction of the cylindrical structure (arrow F2 direction)), and the downward-extending portion (part 501B) corresponding to the wall surface is also folded in the inward direction (the central direction of the cylindrical structure (arrow F2 direction)). At this time, the overlapping portions of part 501A and part 501B, and the overlapping portions of the two parts 501B, are bonded together using an adhesive or the like. In this case, a folded structure 27 is formed at the bottom 22. Alternatively, a reinforcing sealing material or the like may also be attached to the bottom 22.

[0439] [1-2 Functions and Effects]

[0440] According to the bag body of the first embodiment, the operation of the cup holder configured outside the bag body to stabilize the position of the container can be omitted, and the container can be held simply and stably through simple operation.

[0441] Furthermore, the bag body 10 is configured such that when the limiting wall portion 31 is in the second shape state ST2, the position limiting member 30 covers at least a portion of at least one corner portion. In this case, a small space portion 33 can be formed in the main body at the corner portion. In this case, as described above, when the movable part moves from the first position to the second position, the small space portion formed in the state surrounded by the fixed part and the movable part can be ensured to be large, and a state in which a relatively large contents can be easily held can be formed. Regarding the container 200 containing contents such as juice and coffee, the weight of the container 200 is generally relatively heavy from the viewpoint that it is heavier than foods such as bread. When the item contained in the small space portion 33 is such a container 200, the conventional bag body tends to be in a state where the container 200 is biased towards the center of the bottom of the bag body, and the bottom of the bag body will protrude and deform downward, and the shape of the bag body is prone to collapse. In this case, if bread or the like is also contained in the bag body in addition to the container 200, the shape of the bread or the like is also prone to collapse. Regarding this issue, the bag body according to the first embodiment can maintain the container 200 in a corner position within the space 23. Therefore, the shape of the bottom 22 of the bag body 10 is less likely to collapse, and the aforementioned problem can be suppressed.

[0442] [1-3 Variations]

[0443] (Variation Example 1)

[0444] In the bag body of the first embodiment, a waterproof layer may also be formed on the upper surface side of the bottom (Modification 1). When a waterproof layer is provided on the upper surface side of the bottom as in Modification 1, and a container for containing liquid is housed inside the bag body, even if liquid spills inside the bag body, it can more reliably prevent liquid from seeping into the bottom and wetting the lower surface side of the bottom of the bag body, and prevent liquid from leaking out from the bottom due to bottom damage. Examples of waterproof layers include... Figure 5 The waterproof sheet 37 shown in Figure D is laid on the upper surface side of the bottom. Furthermore, the configuration of having a waterproof layer on the upper surface side of the bottom can be achieved by laying the waterproof sheet on the upper surface side of the bottom after the main body of the bag is formed. Alternatively, the waterproof sheet can be laid on the portion corresponding to the bottom of the blank, and the blank with the waterproof sheet laid on it can be folded to form the main body, thereby achieving a configuration of having a waterproof sheet on the upper surface side of the bottom. Alternatively, the configuration of having a waterproof layer on the upper surface side of the bottom can also be achieved by curing a coating film formed by applying a waterproof coating to the portion of the blank corresponding to the bottom, thereby forming a cured waterproof coating layer, and then folding the blank with the waterproof sheet laid on it to form the main body.

[0445] (Variation Example 2)

[0446] In the bag body of the first embodiment, it is also possible that, when the restrictive wall portion is in the second shape state, such as... Figure 6 As shown in B, at least one position limiting member is positioned where the corner portion will not be covered by the limiting wall portion (Modification 2). For such a position limiting member, as... Figure 6 As shown in C, a small space 33 of sufficient size can be formed by appropriately combining the shape deformation of the bag body 10 and the shape deformation of the position limiting member 30. However, from the viewpoint that it is difficult to restore the limiting wall to the second shape state after the limiting wall is set to the first shape state when the bag is in use and before the container is inserted into the bag, it is preferable that when the limiting wall is in the second shape state, the position limiting member is provided in a manner that covers the corner position. (Modification 3)

[0447] The bag body in the first embodiment can also be configured as follows: Figure 7 A, Figure 7 As shown in B, a limiting wall portion is provided, and the forming positions of the joining allowance portion are provided at multiple locations, thereby enabling the formation of multiple small space portions 33. For example... Figure 7 As shown in B, when the component forming the limiting wall portion 31 is arranged such that it surrounds the inner surface of the peripheral wall portion 21 of the main body 20, as Figure 49As shown, a strip for forming the position limiting member 30 is disposed on the blank 500. Furthermore, a joining allowance 32 is formed according to the formation position of the small space portion 33. In addition to using the blank 500 with the joining allowance 32 disposed in this manner, it is also possible to bend it at a predetermined position as described above, thereby obtaining a bag body.

[0448] (Variation Example 4)

[0449] In the bag body of the first embodiment, such as Figure 7 C, Figure 7 As shown in D, the size of the small space is not limited to the size corresponding to that of a single container. The size of the small space can also be set to accommodate multiple containers. Figure 7 C Figure 7 In the example shown by D, in such Figure 7 In a state where a position limiting component is provided as in C, such as Figure 7 As shown in D, two containers can be configured in the small space 33.

[0450] (Variation Example 5)

[0451] In the bag body of the first embodiment, such as Figure 50 A, Figure 50 As shown in B, the position limiting member 30 may also have a limiting wall weakening part 40 provided in the limiting wall part 31.

[0452] (Containment wall vulnerability)

[0453] The vulnerable part 40 of the confinement wall can be as follows Figure 50 A, Figure 50 B represents a half-cut portion. Alternatively, the confinement wall weakening portion 40 can also be a perforated portion (not shown) formed by alternating through portions and non-through portions along a predetermined direction. Figure 50 Figure A is an example of a position limiting component 30 in the bag body 10. Figure 50 B is a schematic representation Figure 50 A diagram showing the state of the longitudinal section along line D2-D2 in A.

[0454] By forming the limiting wall weakening part 40, after the container 200 is placed in the small space part 33, when the container 200 is taken out from the bag body 10, the limiting wall weakening part 40 can be broken, making it easier to take out the container 200.

[0455] (Variation Example 6)

[0456] In the bag body of the first embodiment, such as Figure 51 A, Figure 51 As shown in B, the position limiting member 30 may have a rib-like protrusion 42 provided in the limiting wall portion 31.

[0457] (rib-like concave and convex parts)

[0458] The ribbed protrusions 42 can be like Figure 51 A, Figure 51 As shown in B, it is formed by a printing embossing process. Furthermore, the concave structure 42A and convex structure 42B constituting the rib-like embossed portion 42 are formed in a shape extending in the vertical direction, but this is only one example. For the rib-like embossed portion 42, it is not prohibited to have a configuration where the concave structure 42A and convex structure 42B extend laterally. For the rib-like embossed portion 42, the concave structure 42A and convex structure 42B may also extend obliquely. Figure 51 Figure A is an example of a position limiting component 30 in the bag body 10. Figure 51 B is a schematic representation Figure 51 A diagram showing the state of the longitudinal section of line D3-D3 of A.

[0459] By forming the ribbed protrusions 42, the restricting wall 31 is easily made flexible, and the container 200 and the like can be placed more smoothly into the small space 33. When the container 200 is taken out from the bag body 10, the container 200 can be taken out more easily by slightly stretching the restricting wall 31.

[0460] [2 Second Embodiment]

[0461] [2-1 Composition]

[0462] In the bag body of the second embodiment, such as Figure 8 , Figure 9 As shown, the position limiting member 30 has a limiting wall portion 31 and a clamping wall 50. The bag body of the second embodiment has the same configuration as that of the first embodiment, except that the position limiting member has the clamping wall 50 described above. That is, the bag body of the second embodiment has the configuration of the bag body of the first embodiment, where the position limiting member has a clamping wall. Therefore, in the description of the second embodiment, detailed descriptions of the configuration other than the clamping wall of the position limiting member are omitted.

[0463] (Sandwiched between walls)

[0464] The position limiting member has a clamped wall 50 as described above. When viewed from above (with the vertical direction as the line of sight), the clamped wall is located between the peripheral wall of the main body and the limiting wall of the position limiting member. The clamped wall is engaged with at least the inner surface of the peripheral wall. More specifically, the clamped wall is bonded to the peripheral wall by being adhered to it in a state of surface contact with the inner surface of the peripheral wall. If the portion where the clamped wall and the peripheral wall are bonded is defined as the clamped wall bonding portion 51, the clamped wall bonding portion 51 is preferably formed partially in the area where the clamped wall and the peripheral wall face each other. Furthermore, it is preferable that a gap space portion 52 is formed between the clamped wall and the peripheral wall. By forming the gap space portion 52, a layer of gas such as air can exist between the clamped wall and the peripheral wall, thereby improving the heat insulation performance of the space portion (small space portion) formed by the clamped wall and the peripheral wall in the position limiting member. Figure 8 , Figure 9 A, Figure 9 In example B, the bonded portion of the sandwiched wall is spaced apart along the vertical direction of the peripheral wall to form multiple strips. However, Figure 8 , Figure 9 The example is a case of a bonded portion between two walls. It is not prohibited for the bonded portion to be formed entirely in the area where the bonded wall and the peripheral wall face each other. Furthermore, the layout of the bonded portion can also be as follows... Figure 12 A, Figure 12 As shown in B, set appropriately. For example, Figure 12 In A, the layout of the bonded part of the sandwiched wall becomes... Figure 9 A, Figure 9 The peripheral wall portion shown in B is spaced apart vertically and formed into a multi-strip layout. Figure 12 In section B, the layout of the bonded part of the sandwich wall becomes a diagonally intersecting multi-ribbed diagonal grid-like layout.

[0465] In the second embodiment, preferably, when the restricted wall portion is in the second shape state, such as Figure 10 As shown, the lower end of the limiting wall portion 31 is positioned above the lower end of the clamped wall 50. This configuration allows the container to be placed in a small space while the position limiting member is securely attached to the main body via the clamped wall. This enhances the structural reinforcement effect of the position limiting member and its surrounding area when the container is placed in the small space. Furthermore, from the viewpoint of further enhancing the structural reinforcement effect, it is preferable that the lower end 50A of the clamped wall 50 contacts the bottom 22.

[0466] (Burnt material)

[0467] In the bag body shown in the second embodiment, a position limiting member is disposed at a predetermined position on the blank 500 for forming the main body 20. The position limiting member is fixed to the blank by a clamping wall. Based on the blank with the position limiting member disposed in this way, the bag body can be obtained by bending at the predetermined position as described in the first embodiment.

[0468] [2-2 Functions and Effects]

[0469] The bag body according to the second embodiment can achieve the same effect as the first embodiment.

[0470] [2-3 Variations]

[0471] (Variation Example 1)

[0472] According to the bag body of the second embodiment, the position limiting member is not limited to, for example... Figure 11 The case shown in Figure A, where the limiting wall and the clamped wall are bonded to each other via their side edges. For example... Figure 11 As shown in B, the position limiting component can also be formed integrally with the limiting wall and the clamped wall. Figure 11 In example B, the limiting wall 31 and the clamped wall 50 are formed continuously and integrally, thereby forming the position limiting member in a ring shape. Furthermore, Figure 11 In A, the engagement allowance 32 of the limiting wall portion 31 becomes the portion that engages with the clamped wall 50. Furthermore, Figure 11 In A, the engagement allowance 32 of the limiting wall portion 31 becomes the portion that engages with the clamped wall 50. When the position limiting member 30 is formed in a ring shape, the bag body can be manufactured as described below. Figure 48 As shown in Figure A, a position limiting member 30 is disposed at a predetermined position on the blank 500 used to form the main body 20. The position limiting member 30 is fixed to the blank 500 by a clamping wall 50. At this time, as... Figure 48 As shown in Figure B, a portion of the width direction of the clamping wall 50 can be fixed to the blank 500 by the clamping wall 50 (a portion of the width direction of the clamping wall 50 may also have a clamping wall bonding portion 51). Besides using a blank 500 with the position limiting member 30 configured in this way, it is also possible to bend at a predetermined position as described in the first embodiment, thereby obtaining a bag body. Furthermore, as a method for configuring the position limiting member 30 at a predetermined position on the blank 500 used to form the main body 20 when the position limiting member 30 is formed in a ring shape, such as... Figure 53 As shown in A, a ring-shaped body can be manufactured by rolling a sheet used to form the position limiting member 30 into a ring shape and joining the overlapping ends by bonding or the like, and then placing the ring-shaped body at a predetermined position on the blank 500. Additionally, as... Figure 53As shown in B, it is also possible to roll the sheet used to form the position limiting member 30 into a ring shape and overlap the ends, and make an overlapping body PB with adhesive or the like disposed on at least one side of the overlapping part (the state before the overlapping part is joined by adhesive). The overlapping body PB is placed at a predetermined position on the blank 500, and the overlapping body PB is bonded to the main body 20 by adhesive 51A forming the sandwiched bonding part 51.

[0473] (Variation Example 2)

[0474] The bag body according to the second embodiment may also have a configuration shown in the modified example of the first embodiment.

[0475] [3 Third Embodiment]

[0476] [3-1 Composition]

[0477] In the bag body of the third embodiment, the position limiting member 30 has a limiting wall portion 31 and an inner bottom portion 80, or, as... Figure 13 As shown, the bag includes a limiting wall portion 31, a clamped wall 50, and an inner bottom 80. The bag body of the second embodiment has the same configuration as that of the first or second embodiment, except that the position limiting member has an inner bottom 80. That is, the bag body of the third embodiment has the configuration of the first or second embodiment where the position limiting member has an inner bottom. Therefore, in the description of the second embodiment, detailed descriptions of the configuration other than the inner bottom of the position limiting member are omitted.

[0478] (inner bottom)

[0479] like Figure 13 As shown, the position limiting component has an inner bottom 80. Figure 13 The example illustrates a case where the bag body of the third embodiment is configured such that the position limiting member in the bag body of the second embodiment has a bottom. The inner bottom is sometimes referred to as the small bottom because it is a point smaller than the bottom.

[0480] The inner bottom can be separate from the limiting wall portion, but preferably, it is formed in such a way that the inner bottom is continuously connected to the limiting wall portion. The same applies to the continuity between the inner bottom and the clamped wall. Figure 13 In this example, the inner bottom 80 is formed to be continuous with the clamped wall 50 at its lower end and with the limiting wall 31 at its lower end. The inner bottom 80 supports the contents (e.g., container 200) from below within the space 23 (the interior of the small space 33). When the contents are a container (a container containing a liquid such as a beverage), "supporting the contents from below" means, as... Figure 14A, Figure 14 As shown in B, when the limiting wall portion 31 is deformed from the second shape state ST2 to the first shape state ST1 and the container 200 is disposed in the small space portion 33, the inner bottom 80 is disposed on the lower surface side of the container 200. This includes either the case where the contents are supported only by the inner bottom 80 from the lower surface side, or the case where the contents are supported by both the inner bottom 80 and the bottom 22 from the lower surface side.

[0481] (Inclined surface)

[0482] When the limiting wall portion of the position limiting member is in the first shape state ST1, at least a portion of the inner bottom 80 is preferably, as follows: Figure 15 B Figure 15 As shown in C, it has a direction approaching the peripheral wall from the boundary position TR between the inner bottom and the limiting wall portion. Figure 15 B Figure 15 In section C, an inclined surface 81 slopes downwards in the direction approaching the clamped wall 50. The inclined surface formed on the upper surface side of the inner bottom can be formed over a whole range from the boundary position between the inner bottom and the limiting wall to the boundary position TB between the inner bottom and the clamped wall, or it can be formed in a region from the boundary position between the inner bottom and the limiting wall to a predetermined position of the inner bottom. From the viewpoint of firmly supporting the contents of the container or the like from below by the inner bottom while simultaneously obtaining the effect based on the inclined surface 81, it is preferable that the inclined surface is formed in the region from the boundary position between the inner bottom and the limiting wall to a predetermined position of the inner bottom.

[0483] When the limiting wall portion of the position limiting member is in the first shape state ST1, and an inclined surface as described above is formed on the upper surface side of the inner bottom, when the container containing the contents is placed in the small space, as shown above... Figure 16 As shown, the container 200 is slightly tilted towards the peripheral wall 21 of the main body, and the upper end of the container is easily pressed against the inner surface of the peripheral wall (in the direction of arrow FE), easily forming a gap 35 between the outer peripheral surface of the container body and the upper end of the limiting wall. If a gap is formed between the outer peripheral surface of the container body and the upper end of the limiting wall, even if the contents of the container (such as liquids like beverages) leak from the container body, the contents will easily fall into the gap between the limiting wall and the container body, making it difficult for the contents to overflow and drip outwards.

[0484] (Waterproof)

[0485] Furthermore, in the event that liquid (such as a beverage contained in the container) splashes and drips into the gap between the limiting wall and the container body, it is preferable that the inner bottom be waterproof, based on the viewpoint of preventing "splashed liquid from reaching the inner bottom, causing damage to the inner bottom and reducing the container's support function from below". From the viewpoint of preventing damage to the position limiting member caused by liquid seeping into it, the position limiting member as a whole is preferably waterproof.

[0486] (lining)

[0487] Also Figure 14 A, Figure 15 As shown in A, the inner bottom preferably has a lining 82 (bottom lining). In this case, the inner bottom 80 has a lining portion 83, which allows the state of the limiting wall portion 31 of the position limiting member to smoothly change from the first shape state ST1 to the second shape state ST2, and can change the state of the limiting wall portion 31 from the second shape state ST2 to the first shape state ST1. Furthermore, as described above, if an inclined surface 81 is formed on the upper surface of the inner bottom, such as... Figure 15 As shown in Figure A, when the limiting wall portion is in the second shape state, it is preferable that the lower end of the limiting wall portion is positioned above the lower end of the clamped wall. In this case, if the state of the limiting wall is changed from the second shape state to the first shape state, the lower end of the limiting wall portion will be positioned above the lower end of the clamped wall, thereby more reliably forming the inclined surface 81 on the upper surface of the inner bottom 80.

[0488] [3-2 Functions and Effects]

[0489] The bag body according to the third embodiment can achieve the same effect as the first embodiment. Furthermore, the bag body of the third embodiment, having the same configuration as the second embodiment, can achieve the same effect as the second embodiment.

[0490] According to the third embodiment, the bag has an inner bottom 80, thereby significantly reducing the likelihood of the bag getting wet from the liquid even if the beverage leaks from the container.

[0491] [3-3 Variation Example]

[0492] (Variation Example 1)

[0493] According to the bag body of the third embodiment, such as Figure 17 A, Figure 17 As shown in B, the clamping wall can also be omitted from the position limiting component (Modification 1). Figure 17 A, Figure 17In example B, the outer edge 84 of the inner bottom 80 (the outermost edge of the inner bottom 80) engages with the peripheral wall portion. In this case, when the wall portion is restricted to the second shape state, as... Figure 17 As shown in B, the lower end of the limiting wall is preferably located on the upper side compared to the lower end of the outer edge 84 of the inner bottom 80.

[0494] (Variation Example 2)

[0495] In the third embodiment of the bag, an absorbent body may be provided on the upper surface of the inner bottom 80 to absorb liquid flowing down from the outer periphery of the container. Examples of absorbent bodies include facial tissues and SAP (Super Powdered Facial Tissue).

[0496] (Variation Example 3)

[0497] According to the bag body of the third embodiment, it may also be provided with the configuration shown in the modified examples of the first embodiment and the modified examples of the second embodiment.

[0498] [4 Fourth Implementation]

[0499] [4-1 Composition]

[0500] The bag body of the fourth embodiment has a configuration in which the position limiting member is provided with a limiting wall reinforcement structure, as in any one of the bag bodies of the first to third embodiments.

[0501] (Reinforced confinement wall structure)

[0502] like Figure 18 , Figure 19 As shown, the reinforcing structure of the limiting wall is a folded-back section or a reinforcing component. Figure 18 A, Figure 18 B Figure 18 The C indicates that the confinement wall reinforcement structure is an example of the case of the fold-back section 100. Figure 19 A, Figure 19 B indicates that the confinement wall reinforcement structure is an example of the case of reinforcement component 101.

[0503] (Return section)

[0504] When the reinforcing structure of the limiting wall is a folded-back portion 100, in the position limiting component, such as Figure 18 As shown in A, a folded-back portion 100 is formed at the upper end 36 of the limiting wall portion 31. Figure 18 In the folded-back section 100 shown in Figure A, a predetermined portion on the upper end 36 side of the limiting wall section 31 folds back towards the opposite surface 34. However, this is just one example; the folded-back section can also be as follows: Figure 18As shown in C, a defined portion on the upper end side of the limiting wall folds back towards the opposite side of the opposing surface 34. The face-to-face portions between the folded-back portion and the non-folded-back portion of the limiting wall can be joined together by an adhesive. Furthermore, as... Figure 18 As shown in B, when the lower end of the limiting wall portion is positioned above the lower end of the clamped wall, it is preferable that a fold-back portion 100 is formed at the upper end 36 of the limiting wall portion 31. When the lower end of the limiting wall portion is positioned above the lower end of the clamped wall, it is easier to form an inclined surface 81 on the upper surface of the inner bottom 80, and to form the fold-back portion 100 at the upper end 36 of the limiting wall portion 31. This further stabilizes the shape of the upper end 36 of the limiting wall portion 31, stabilizes the shape of the gap 35, and improves the effect based on the inclined surface 81.

[0505] (Reinforced components)

[0506] When the limiting wall reinforcement structure is the reinforcing member 101, in the position limiting member, such as Figure 19 A, Figure 19 As shown in B, a reinforcing member 101 is provided at the upper end 36 of the limiting wall portion 31. The reinforcing member 101 can be disposed on either the side opposite to the opposing surface 34 or the side facing away from the opposing surface 34. The reinforcing member 101 can also be disposed on both sides, opposite to the opposing surface 34 and the side facing away from the opposing surface 34. Furthermore, the material of the reinforcing member 101 is not particularly limited. Examples of materials for the reinforcing member include paper, resin (resin sheet), and metal, but from the viewpoints of reducing environmental burden and ease of disposal after use, paper is preferred. As the material for the reinforcing member, a material with greater toughness than the position limiting member is preferred.

[0507] (Combination of reinforced components and fold-back sections)

[0508] As a confinement wall reinforcement structure, it can also be, for example, Figure 20 A, Figure 20 B Figure 20 As shown in C, it is reinforced with a reinforcing member 101 and a fold-back portion 100. For example, in Figure 20 A, Figure 20 In example B, the upper end of the limiting wall portion is provided with a reinforcing member 101, and the upper end of the limiting wall portion 31 has a folded-back portion 100, which is formed in a manner that covers the reinforcing member 101 (in a manner that wraps the reinforcing member 101).

[0509] Furthermore, it is not limited to the case where the reinforcing member is wrapped by a folded-back section; it can also be, for example... Figure 20 As shown in C, a reinforcing member 101 is attached to the outside of the folded-back portion 100.

[0510] [4-2 Functions and Effects]

[0511] According to the bag body of the fourth embodiment, the same effect as any of the bag bodies of the first to third embodiments can be obtained. In addition, in the bag body of the fourth embodiment, the position limiting member is made more resilient, thereby making it less likely for the bag body to collapse when the container is placed in a small space.

[0512] [4-3 Variation Example]

[0513] (Variation Example 1)

[0514] In the bag body of the fourth embodiment, the reinforcing member may also be disposed on the surface of the restricting wall in such a way that the vertical direction is set as the long side direction of the reinforcing member (Modification 1).

[0515] (Variation Example 2)

[0516] According to the fourth embodiment, the bag body may also be configured as shown in the variations of the first embodiment, the second embodiment, and the third embodiment.

[0517] [5 Fifth Embodiment]

[0518] [5-1 Composition]

[0519] like Figure 21 A, Figure 21 B Figure 21 As shown in C, the bag body of the fifth embodiment has a cover portion 120 in any one of the bag bodies of the first to fourth embodiments, and an adhesive dispensing portion 121 is provided in the cover portion 120. Figure 21 A to Figure 21 In example C, one case is given where the peripheral wall portion 21 has a set of facing wall portions 25 and is provided with a cover portion and an adhesive preparation portion.

[0520] (Zhoubi section)

[0521] Figure 21 The example shows a peripheral wall portion having a set of facing wall surfaces. The set of wall surfaces 25 is designated as a first wall surface 25A and a second wall surface 25B. Furthermore, the terms first wall surface 25A and second wall surface 25B are used merely for ease of explanation, and the terms first wall surface 25A and second wall surface 25B can be used interchangeably.

[0522] (cover part)

[0523] A cover is formed at the upper end of the first wall surface in a manner that allows it to cover the upper end of the second wall surface. The shape of the cover is not particularly limited. Figure 21 In example B, it is formed into a trapezoidal shape. For example... Figure 22 A, Figure 22 B Figure 22 As shown in C, by covering the upper end of the second wall surface with the cover portion 120, a state is formed in which the opening is firmly sealed. According to the viewpoint of forming this state, the cover portion is preferably formed over the entire width of the first wall surface. Figure 22 A, Figure 22 B Figure 22 Figure C illustrates the state in which the opening 24 is sealed by the cover 120.

[0524] (Adhesive Preparation Department)

[0525] Preferably, the cover portion 120 is provided with an adhesive placement portion 121 on which adhesive is disposed, which can adhere to the second wall surface when the upper end of the second wall surface is covered by the cover portion. Examples of adhesive placement portions 121 include sealing components. Double-sided tape can be an example of a sealing component.

[0526] (Remove paper)

[0527] When the bag is not in use, from the viewpoints of preventing trash and other debris from adhering to the adhesive application area and preventing the adhesive application area from coming into contact with unintentional items, it is preferable to install a release paper 122 in a manner that covers the surface of the adhesive application area. The release paper is configured to be able to be removed from the surface of the adhesive application area when the bag is not in use (by peeling off the release paper) when the bag is in use. As the release paper, a sealing material formed of a material with weak adhesion to the adhesive constituting the adhesive application area can be used.

[0528] Furthermore, the release liner can be completely separated from the bag body, but it is preferably configured as follows: Figure 22 A to Figure 22 As shown in C, even after the release paper is peeled off from the adhesive attachment in a manner that prevents the release paper from separating, a portion of the release paper remains adhered to the bag body 10. In this case, the possibility of the release paper 122 separating from the bag body and becoming a separate waste item can be suppressed.

[0529] [5-2 Functions and Effects]

[0530] According to the bag body of the fifth embodiment, the same effect as any of the bag bodies of the first to fourth embodiments can be obtained. In addition, in the bag body of the fifth embodiment, the opening 24 of the bag body is closed, thereby improving the heat insulation of the space portion 23.

[0531] [5-3 Variation Example]

[0532] (Variation Example 1)

[0533] In the fifth embodiment, the bag body may also be, for example, Figure 23 A, Figure 23 B Figure 23 As shown in Figure C, a grip portion 130 is provided at a predetermined position on the first wall surface. The shape of the grip portion is not particularly limited as long as it is configured to allow a user to hold the grip portion 130 with their hand. Figure 23 A to Figure 23 In the example shown in C, the gripping part has a rectangular outer end and a chamfered rectangular through hole 131 inside. Furthermore, in this example, the through hole is an elongated hole with a slender shape along the transverse direction.

[0534] (The first example of the gripping part)

[0535] Figure 23 The example illustrates a first embodiment of the grip portion 130. In this first embodiment, the grip portion 130 is integrally formed with the peripheral wall portion 21. The base end of the grip portion 130 may be located at a position common to the base end of the cover portion 120, or it may be formed at a position lower than the cover portion. Regarding such a bag body 10, as... Figure 24 A, Figure 24 B Figure 24 As shown in Figure C, by covering the upper end of the second wall portion 25B with the cover portion 120, a state in which the opening portion 24 is securely sealed can be formed. Furthermore, when the opening portion 24 is sealed, as... Figure 24 A to Figure 24 As shown in C, the grip part 130 stands upright, and the bag body 10 can be easily picked up by passing the fingers through the through hole 131 of the grip part 130.

[0536] (The second example of the gripping part)

[0537] Figure 26 The example illustrates a second embodiment of the grip portion 130. In this second embodiment, the handle member 140, which forms the grip portion and the cover portion, is formed independently of the peripheral wall portion. The handle member 140 is attached to the first wall portion 25A with the adhesive portion 141 facing the outer side of the first wall portion in the direction of arrow FB, thereby forming a situation where the cover portion 120 and the grip portion 130 are arranged on the upper end side of the first wall portion 25A.

[0538] In either the first or second example of the gripping part 130, the gripping part 130 can be configured as follows: Figure 23 , Figure 24As shown in the example, it stands upright with the upper end of the second wall surface covered by the cover 120. Alternatively, it can be pre-connected with... Figure 26 The example shows the grip being configured to stand upright in the upward direction. Alternatively, in the bag body 10, the cover may be configured such that the front end of the cover faces downward.

[0539] According to a variation of the fifth embodiment, a gripping part is provided, thereby improving the ease of carrying the bag.

[0540] (Variation Example 2)

[0541] In the fifth embodiment, the bag body may also be, for example, Figure 25 A, Figure 25 As shown in B, a vulnerable part is provided at a specified position on the first wall surface. Figure 25 A, Figure 25 In example B, an embodiment is shown in which a fragility part is provided in the bag body of variation 1 of the fifth embodiment.

[0542] (Vulnerability Section)

[0543] The vulnerable part can be as follows Figure 25 A, Figure 25 As shown in B, the perforated portion 150, which is formed by alternating through portions 152 and non-through portions 151 along a prescribed direction, may also be a half-cut portion. Figure 25 A is a diagram representing an example of bag 10 when not in use. Figure 25 B is a diagram representing an example of the bag 10 in use.

[0544] The weakened portion is preferably located in the first wall surface at a position that avoids the cover portion or a portion that avoids the adhesive placement portion in the cover portion (wherein, along the position of the cover portion, it is located closer to the base end side of the cover portion than the formation position of the adhesive placement portion). By positioning the weakened portion in such a way, the opening can be opened (the closure of the opening based on the cover portion can be released) by breaking the weakened portion.

[0545] From the viewpoint of effectively suppressing the breakage of the bag body originating from the vulnerable portion, it is preferable to avoid the formation of vulnerable portions near the peripheral edge of the cover. This can be achieved when the vulnerable portion is a perforated portion with alternating through portions and non-through portions along a predetermined direction, by forming the perforated portion in a manner that arranges the non-through portions near the peripheral edge of the cover.

[0546] (Variation Example 3)

[0547] In the case where a release liner is provided in the bag body according to the fifth embodiment, a labeling section may also be provided on the exposed side of the release liner. Examples of labeling sections include a printed section on the exposed side of the release liner and a structural section for attaching the printed sheet to the exposed side of the release liner. By providing a labeling section, the contents contained in the bag can be recorded on the labeling section, so that the user can recognize the contents contained in the bag even if the opening of the bag body is not in an open state.

[0548] (Variation Example 4)

[0549] According to the fifth embodiment, the bag body may also be configured as shown in the variations of the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment.

[0550] [5-4 Reference Example]

[0551] According to the fifth embodiment of the bag body, the aforementioned cover and / or gripping portion may also be provided in the bag body from the first to the fourth embodiment, in which the position limiting component is omitted (that is, a bag body consisting only of the main body) in which the above-mentioned cover portion and / or gripping portion are provided (reference example). In the case of the reference example, the aforementioned fragility portion may also be provided.

[0552] [6. Sixth Implementation]

[0553] [6-1 Composition]

[0554] like Figure 64 A, Figure 64 As shown in B, in any one of the bag bodies of the first to fifth embodiments (except for the reference example), the bag body of the sixth embodiment has a receiving portion 155 provided in the limiting wall portion 31 of the position limiting member 30. The receiving portion 155 is a structure capable of receiving liquid falling from above the limiting wall portion 31. Examples of receiving portions 155 include... Figure 64 A and Figure 64 The upward-opening groove 156 and the upward-opening pocket shown in Figure B, etc. The receiving portion 155 can be as follows: Figure 64 As shown in the example, C is provided on the opposite side of the limiting wall 31, or as... Figure 64 A and Figure 64 As shown in section B, it is located on the side opposite to the opposing surface 34. The receiving portion 155 can be formed of the same material as the limiting wall portion 31. The receiving portion 155 is preferably configured such that at least a portion of its upper end can deform in a direction away from the limiting wall portion 31. Such a receiving portion 155 can be achieved by forming the receiving portion 155 from a material that can be deformed, such as paper. Furthermore, Figure 64 A and Figure 64B is a cross-sectional view used to illustrate the bag body 10 of the sixth embodiment. Figure 64 In A, a portion of the limiting wall 31 of the position limiting member 30 is represented. Figure 64 Example B illustrates a case where the container 200 is housed within the bag 10. Additionally, Figure 64 C is a cross-sectional view used to illustrate the bag body 10 of the sixth embodiment.

[0555] [6-2 Functions and Effects]

[0556] According to the sixth embodiment, the bag body has a receiving part, and when a container containing liquid or the like is stored in the bag body, the receiving part can easily block the liquid from splashing out of the container.

[0557] [7. Implementation Method 7]

[0558] [7-1 Composition]

[0559] The bag body of the seventh embodiment has an adhesive member 160 as shown below, which is attached to the main body 20.

[0560] In the bag body 10 of the seventh embodiment, as Figure 27 A to Figure 27 As shown in Figure C, the main body 20 has a bottom 22 and a peripheral wall portion 21 connected to the bottom 22. The peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of facing wall portions 25. The main body 20 forms a space portion 23 enclosed by the bottom 22 and the peripheral wall portion 21, which can accommodate contents (container 200, etc.), and an opening portion 24 for inserting the contents into the space portion 23. In the bag body 10 of the seventh embodiment, as... Figure 27 A to Figure 27 As shown in C, an adhesive member 160 is attached to the outer surface 21B of the peripheral wall portion 21. Furthermore, the structure of the main body 20 (peripheral wall portion 21 and bottom 22) is the same as that described in the first to sixth embodiments, therefore detailed descriptions are omitted.

[0561] (Adhesive components)

[0562] The adhesive member 160 has a first adhesive surface forming portion 161 and a second adhesive surface forming portion 162. In the adhesive member 160, the first adhesive surface forming portion 161 is adhered to a predetermined area of ​​the outer surface of the first wall surface portion 25A. Furthermore, the bag body 10 of the seventh embodiment is configured such that, when the curved structure 170 described later is formed, at least a portion of the second adhesive surface forming portion 162 can be adhered to the outer surface of the second wall surface portion 25B. The adhesive member 160 is arranged such that the second adhesive surface forming portion 162 extends across the lower end 173 of the curved structure 170.

[0563] The first adhesive surface forming portion 161 and the second adhesive surface forming portion 162 are not particularly limited as long as they are configured in a manner that allows the bending structure 170 to be formed as described later. Figure 27 In example B, the first adhesive surface forming portion 161 and the second adhesive surface forming portion 162 are formed in the separated region, but the first adhesive surface forming portion 161 and the second adhesive surface forming portion 162 can also be connected.

[0564] The shape of the adhesive component 160 is not particularly limited as long as it can form the first adhesive surface forming portion 161 and the second adhesive surface forming portion 162. Figure 27 A to Figure 27 In example C, the adhesive member 160 is formed in a U-shape, but this is just one example. From the viewpoint that the curved structure 170 can be stabilized and a grippable gap 171 can be formed, the shape of the adhesive member 160 is preferably such that the second adhesive surface forming portion 162 is located near the two ends of the curved structure 170 which are separated in the long side direction of the curved structure 170, and the first adhesive surface forming portion 161 is located at a position detached from the curved structure 170.

[0565] (Bent structure)

[0566] The bending structure 170 is defined as a portion formed by bending the first wall surface 25A and the second wall surface 25B such that the outer surfaces of the first wall surface 25A and the second wall surface 25B face each other, with a predetermined portion (first upper side wall surface portion 165A) on the upper end side of the first wall surface 25A and a predetermined portion (second upper side wall surface portion 165B) on the upper end side of the second wall surface 25B overlapping. The overlapping state of the first upper sidewall portion 165A and the second upper sidewall portion 165B includes not only a state in which the inner surfaces of the first upper sidewall portion 165A and the second upper sidewall portion 165B are in contact, but also a state in which the distance Wh between the first upper sidewall portion 165A and the second upper sidewall portion 165B is narrower than the sum of the thicknesses of the first upper sidewall portion 165A and the second upper sidewall portion 165B. Preferably, the overlapping state of the first upper sidewall portion 165A and the second upper sidewall portion 165B is a state in which the inner surfaces of the first upper sidewall portion 165A and the second upper sidewall portion 165B are in contact.

[0567] Furthermore, the portion of the peripheral wall portion 21 that is predetermined to form the curved structure 170 is referred to as the first peripheral wall portion forming portion 166, and the portion other than the first peripheral wall portion forming portion 166 is referred to as the second peripheral wall portion forming portion 167. That is, assuming that the bag body 10 has the curved structure 170, the portion forming the curved structure 170 is referred to as the first peripheral wall portion forming portion 166, and the portion other than the first peripheral wall portion forming portion 166 is referred to as the second peripheral wall portion forming portion 167. Specifically, the first peripheral wall portion forming portion 166 is defined as the portion of the peripheral wall portion 21 defined by the range from the portion formed by the opening 24 that will become the end of the peripheral wall portion 21 to the portion of the curved peripheral wall portion 21 near the bottom 22.

[0568] Figure 27 A to Figure 27 In the example of bag body 10 shown in C, the curved structure 170 is preferably as follows: Figure 28 , Figure 29 It is formed as shown. That is to say, as... Figure 28 A, Figure 28 As shown in B, a predetermined portion of the first peripheral wall forming portion 166 that is located above the upper end of the first adhesive surface forming portion 161 is folded toward the second wall surface portion 25B. At this time, the upper end of the main body 20 of the bag body 10 becomes the folded end (first folded end 172). Figure 28 In example A, the second adhesive surface forming portion 162 protrudes upward from the first bent end 172.

[0569] From a state where the first folded end 172 is set as the upper end, the bag body 10 further folds the first circumferential wall forming portion 166 at the lower end of the first circumferential wall forming portion 166 in a direction toward the second wall surface 25B. That is, the first circumferential wall forming portion 166 is folded multiple times (…). Figure 28 , Figure 29 (In the example, there are two bends). At this time, as... Figure 29 As shown, a curved structure 170 is formed. Therefore, Figure 29 A, Figure 29 In example B, the bending structure 170 is defined by a portion formed by bending the first wall surface 25A and the second wall surface 25B toward the second wall surface 25B in such a way that the outer surfaces of the first wall surface 25A and the second wall surface 25B face each other. Figure 29 A, Figure 29 In example B, the curved structure 170 becomes a folded structure formed by multiple folds. Since the curved structure 170 becomes the aforementioned folded structure, the opening 24 is concealed within the curved structure 170.

[0570] Furthermore, in the case where a curved structure 170 is formed, such as Figure 29 A, Figure 29 As shown in Figure B, at least a portion of the second adhesive surface forming portion 162 is positioned such that it does not face the outer surface of the second wall surface portion 25B via the first wall surface portion 25A. That is, when the curved structure 170 is formed, the position of the adhesive member 160 is defined such that at least a portion of the second adhesive surface forming portion 162 is bonded relative to the outer surface of the second wall surface portion 25B. Furthermore, when the curved structure 170 is not formed, as... Figure 27 A to Figure 27 As shown in C, the second adhesive surface forming portion 162 avoids adhesion relative to the outer surface 21B of the peripheral wall portion 21.

[0571] In the case where a curved structure 170 is formed, such as Figure 30 A, Figure 30As shown in B, preferably, the second adhesive surface forming portion 162 is bonded to at least the outer surface of the second wall surface portion 25B. This bonding of the second adhesive surface forming portion 162 to the outer surface of the second wall surface portion 25B facilitates the fixing of the curved structure 170. The curved structure 170 conceals the opening 24 as described above, and the bonding of the second adhesive surface forming portion 162 to at least the second wall surface portion 25B prevents third parties other than the user from opening the opening 24 of the bag and improperly inserting their hands into the bag 10 through the opening 24. Furthermore, the bonding of the second adhesive surface forming portion 162 to at least the outer surface of the second wall surface portion 25B stabilizes the curved structure 170. Therefore, the structure of the "gripable gap 171" (described later) formed along with the curved structure 170 can be stabilized.

[0572] (gap)

[0573] When the second adhesive surface forming portion 162 is bonded to the peripheral wall portion 21, it is preferably configured such that a grippable gap 171 can be formed between the first peripheral wall portion forming portion 166 in which the curved structure 170 is formed and the second peripheral wall portion forming portion 167 other than the first peripheral wall portion forming portion 166. By forming such a gap 171, the user can insert their hand into the gap 171 and hold the bag by hand. In this case, by fixing the curved structure 170, the opening 24 is closed, thereby restricting the hand from being inserted into the space portion 23 through the gap 171.

[0574] (Removed parts)

[0575] The bag body 10 in the seventh embodiment is preferably, as follows: Figures 27 to 30 As shown, a peeling member 175 with peelability is installed to cover the second adhesive surface forming portion 162. As the peeling member 175, so-called release paper can preferably be used. Preferably, the peeling member 175 is arranged to cover the second adhesive surface forming portion 162 in a state where the curved structure 170 is not formed. Furthermore, even when the curved structure 170 is formed, the peeling member 175 peels off the second adhesive surface forming portion 162 in a manner that exposes the second adhesive surface forming portion 162.

[0576] Additionally, the peeling member 175 may be configured to prevent complete separation from the adhesive member 160. Figure 30 In example A, the peeling member 175 is engaged at the end of the adhesive member 160 (the end of the second adhesive surface forming portion 162 that is more located at the front end), so that even if the peeling member 175 is peeled off from the second adhesive surface forming portion 162, the peeling member 175 can be maintained in a state where it is connected at the end of the adhesive member 160.

[0577] also, Figure 30 A, Figure 30 B does not prohibit the peeling part 175 from being completely separated from the adhesive part 160.

[0578] [7-2 Functions and Effects]

[0579] According to the seventh embodiment, the bag body 10 is formed with an adhesive member 160 and a curved structure 170 having the above-described configuration, thereby forming a grippable gap 171, allowing the user to insert their hand into the gap 171 to carry the bag body 10. Furthermore, by forming the adhesive member 160 and the curved structure 170, the curved structure 170 can be stabilized, and the opening 24 can be stably concealed, thereby suppressing the risk of a third party improperly inserting their hand into the space 23 through the opening 24.

[0580] [7-3 Variation Example]

[0581] (Variation Example 1)

[0582] Regarding the bag body 10 of the seventh embodiment, in Figure 29 In one example, the second adhesive surface forming portion 162 is configured to adhere to the second wall surface portion 25B when the curved structure 170 is formed, but this is only one example. The bag body 10 of the seventh embodiment can also be configured such that, when the curved structure 170 is formed, the second adhesive surface forming portion 162 can adhere to the first wall surface portion 25A and the second wall surface portion 25B (Modification 1). In this case, when the curved structure 170 is formed, it is preferable that the second adhesive surface forming portion 162 is disposed across the lower end 173 of the curved structure 170 and adheres to the outer surfaces of the first wall surface portion 25A and the second wall surface portion 25B. The curved structure 170 conceals the opening 24 as described above, and the second adhesive surface forming portion 162 is partially bonded to at least both the outer surfaces of the first wall surface 25A and the second wall surface 25B. This effectively prevents unauthorized opening of the bag body 10 by a third party other than the user. Specifically, the second adhesive surface forming portion 162 is positioned across the lower end 173 of the curved structure 170 and bonded to the first wall surface 25A and the second wall surface 25B. Therefore, if a third party other than the user unauthorizedly opens the opening 24 of the bag body 10, improper marks may easily remain due to breakage of the adhesive component 160. This effectively prevents unauthorized insertion of hands into the bag body 10 through the opening 24.

[0583] (Variation Example 2)

[0584] In the seventh embodiment, the bag body 10 may also have the curved structure 170 as shown in the example. Figure 36 A, Figure 36 As shown in B, it is defined by the portion formed by bending the first wall surface 25A and the second wall surface 25B toward the first wall surface 25A with the outer surface of the first wall surface 25A facing each other.

[0585] [7-3 Reference Example]

[0586] In the seventh embodiment of the bag, the position limiting component may be omitted from the bag bodies of each of the first to sixth embodiments (that is, as shown in the example). Figure 31 As shown, the aforementioned adhesive component 160 (reference example) is provided in the bag body (consisting only of the main body). Additionally, as... Figure 32 As shown, it is also possible that in the main body 20, an adhesive preparation part 179 for sealing the opening is provided on the inner surface 21A of the peripheral wall portion 21. Figure 32 In this example, the adhesive placement part 179 for sealing the opening is disposed on the upper end side of the peripheral wall part 21 and on the inner surface side of the peripheral wall part 21. Examples of this adhesive placement part include double-sided tape.

[0587] [8. Implementation Method 8]

[0588] [8-1 Composition]

[0589] The bag body 10 of the eighth embodiment has a sealing sheet 180 as shown below in any one of the bag bodies 10 of the first to seventh embodiments.

[0590] In the bag body 10 of the eighth embodiment, the main body 20 has a bottom 22 and a peripheral wall portion 21 connected to the bottom 22. The peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of facing wall portions. The main body 20 forms a space portion 23 enclosed by the bottom 22 and the peripheral wall portion 21 that can hold contents, and an opening portion 24 for inserting the contents into the space portion 23. In the bag body 10 of the eighth embodiment, as... Figure 33 A to Figure 33 As shown in Figure B, a sealing sheet 180 is attached to the outer surface 21B of the peripheral wall portion 21. Furthermore, the structure of the main body 20 (peripheral wall portion 21 and bottom 22, etc.) is the same as described in the first to seventh embodiments, therefore detailed descriptions are omitted. In the figures showing an example of the eighth embodiment (…),… Figures 33 to 35 as well as Figure 37 For ease of explanation, the description of the position limiting component 30 has been omitted in (etc.).

[0591] (Sealing sheet)

[0592] The sealing plate 180 has a sealing component 181 that can be easily installed and removed. Figure 33 A, Figure 33 In example B, the sealing member 181 is detachably and removably attached to the sealing base 182. The sealing member 181 has an adhesive surface forming portion 183, which is detachably and removably attached to the surface of the sealing base 182 when the adhesive surface forming portion 183 faces the sealing base 182. Furthermore, "detachable" means that it can be peeled off and re-attached relative to the surface of the sealing base 182 (the case of "re-attachable" also includes situations where the adhesive force of the sealing member 181 to the sealing base 182 decreases when re-attached). The sealing sheet 180 is attached to a predetermined area of ​​the outer surface 21B of the peripheral wall portion 21. Moreover, in the bag body 10 of the seventh embodiment, the sealing sheet 180 is attached to the outer surface 21B of the peripheral wall portion 21 in a manner that avoids the portion of the peripheral wall portion 21 in which the curved structure 170 is formed. Furthermore, Figure 33 A, Figure 33 In example B, the sealing sheet 180 is adhered to the second wall portion 25B in the peripheral wall portion 21, but this is only one example. At least a portion of the sealing sheet 180 can also be adhered to the portion detached from the second wall portion 25B.

[0593] (Sealing components)

[0594] In the bag body 10 of the seventh embodiment, when the curved structure 170 described later is formed, the sealing member 181 is arranged to extend across the lower end 173 of the curved structure 170 (condition 1). The sealing member is configured such that, when the curved structure 170 is formed, the adhesive surface forming portion 183 can be bonded to the peripheral wall portion 21 with the first wall portion 25A and the second wall portion 25B facing each other (condition 2).

[0595] The shape and number of sealing components 181 of the sealing sheet 180 are not particularly limited as long as they are configured in a manner that satisfies conditions 1 and 2 above. Figure 33 A, Figure 33 In example B, the sealing component 181 is composed of two rectangular sealing materials with a specified size.

[0596] (Sealing base)

[0597] The sealing base 182 can preferably be a component that has a peelable surface as one surface. With the peelable surface as the surface (the peelable surface relative to the sealing component 181 facing the surface side), the back side of the sealing base 182 is attached to the peripheral wall portion 21, thereby being disposed on the outer surface 21B of the peripheral wall portion 21.

[0598] (Bent structure)

[0599] Regarding the bag body of the eighth embodiment, the bending structure 170 is defined by the same definition as the bending structure described in the seventh embodiment. That is, the bending structure 170 is defined by bending the outer surfaces of the first wall surface 25A and the second wall surface 25B together such that a predetermined portion (first upper wall surface portion 165A) on the upper end side of the first wall surface 25A coincides with a predetermined portion (second upper wall surface portion 165B) on the upper end side of the second wall surface 25B.

[0600] The first upper sidewall portion 165A and the second upper sidewall portion 165B are also defined using the same definitions as those used for the curved structure described in the seventh embodiment. Here, similarly to the description in the seventh embodiment, the defined portion on the upper side of the peripheral wall portion 21 that is predetermined to constitute the curved structure 170 is referred to as the first peripheral wall portion forming portion 166, and the portion other than the first peripheral wall portion forming portion 166 is referred to as the second peripheral wall portion forming portion 167. In other words, assuming a state where the bag body 10 has the curved structure 170, the portion forming the curved structure 170 is referred to as the first peripheral wall portion forming portion 166, and the portion other than the first peripheral wall portion forming portion 166 is referred to as the second peripheral wall portion forming portion 167. Specifically, the first peripheral wall forming portion 166 is defined as the portion of the peripheral wall portion 21 defined by the range from the portion formed by the opening 24 that will become the end of the peripheral wall portion 21 to the portion of the curved peripheral wall portion 21 that is close to the bottom 22.

[0601] Figure 33 In the example of bag body 10 shown in A, the curved structure 170 is preferably as follows: Figure 33 B Figure 37 A, Figure 37 As shown in B, it is formed. That is to say, as... Figure 33 B Figure 37 A, Figure 37 As shown in Figure B, with the first upper sidewall portion 165A and the second upper sidewall portion 165B overlapping, the first peripheral wall portion forming portion 166 folds back multiple times toward the second wall portion 25B. At this time, as... Figure 33 B Figure 37 A, Figure 37 As shown in B, a curved structure 170 is formed. Therefore, in Figure 33 B Figure 37 A, Figure 37In example B, the bending structure 170 is defined by bending the first wall portion 25A and the second wall portion 25B towards the second wall portion 25B in a state where the outer surface of the first wall portion 25A faces the outer surface of the second wall portion 25B (the outer surface of the first wall portion 25A coincides with the outer surface of the second wall portion 25B). Figure 33 B Figure 37 A, Figure 37 In example B, the curved structure 170 becomes a folded structure formed by multiple folds. Since the curved structure 170 becomes the aforementioned folded structure, the opening 24 is concealed within the curved structure 170.

[0602] also, Figure 33 The bent structure 170 shown in B is an example. The bent structure 170 may also be defined by bending the first wall surface 25A and the second wall surface 25B toward the first wall surface 25A with the outer surface of the first wall surface 25A facing the outer surface of the second wall surface 25B.

[0603] In the case where a curved structure 170 is formed, such as Figure 33 B Figure 37 As shown in Figure A, the sealing member 181 extends from the sealing sheet 180. Furthermore, the sealing member 181 is disposed on the outer surface 21B of the peripheral wall portion 21, extending across the lower end 173 of the curved structure 170. At this time, the sealing member 181 is bonded to the peripheral wall portion 21 with the adhesive surface forming portion 183 facing the first wall surface portion 25A and the second wall surface portion 25B. The curved structure 170 is fixed by bonding the sealing member 181 relative to the first wall surface portion 25A and the second wall surface portion 25B.

[0604] In addition, sealing component 181 Figure 33 In the example shown in B, the arrangement is near both ends of the curved structure 170 along the long side direction, but this is just one example.

[0605] Regarding the bag body 10 of the eighth embodiment, when the sealing member 181 is adhered to the peripheral wall portion 21, it is also as follows: Figure 37 As shown in B, the configuration allows for the formation of a grippable gap 171 between the first peripheral wall forming portion 166 constituting the curved structure 170 in the peripheral wall portion 21 and the second peripheral wall forming portion 167 (excluding the first peripheral wall forming portion 166), as described in the seventh embodiment. By forming such a gap 171, the user can insert their hand into the gap 171 and carry the bag 10 by holding it in their hand.

[0606] [8-2 Functions and Effects]

[0607] According to the eighth embodiment, the bag body 10 is provided with a sealing member 181. Therefore, when the curved structure 170 is provided, the grippable gap 171 can be stably formed as a structure, allowing the user to insert their hand into the gap 171 to carry the bag body 10. Furthermore, by fixing the curved structure 170 with the sealing member 181, the curved structure 170 is stabilized, and the opening 24 can be stably concealed, thereby suppressing the risk of a third party improperly inserting their hand into the space 23 through the opening 24.

[0608] [8-3 Variation Example]

[0609] (Variation Example 1)

[0610] The eighth embodiment can also be, for example Figure 34 A, Figure 34 B Figure 35 A, Figure 35 As shown in B, the sealing member 181 has a through hole 184 (Modification 1). In this case, the through hole 184 is configured such that when the sealing member 181 is bonded to the outer surface 21B of the peripheral wall portion 21, the gap 171 can be exposed through the through hole 184. Figure 34 A, Figure 34 In B, this represents an example of a case where through hole 184 is formed. Figure 35 A, Figure 35 In B, it indicates that through-hole 184 forms multiple ( Figure 35 A, Figure 35 This is an example of a case where there are three in B.

[0611] [8-4 Reference Example]

[0612] (See Example 1 for reference)

[0613] In the bag body of the eighth embodiment, it is also possible to omit the position limiting member from each of the bag bodies in the first to sixth embodiments (that is, as shown in the example). Figure 31 As shown, the bag body (consisting only of the main body) is provided with the aforementioned sealing sheet 180 (Ref. Example 1). In the case of the reference example, as Figure 32 As shown, an adhesive dispensing section 179 for sealing the opening may also be provided. The adhesive dispensing section 179 for sealing the opening is disposed on the upper end side of the peripheral wall portion 21 and on the inner surface 21A side of the peripheral wall portion 21. Examples of this adhesive dispensing section 179 include double-sided tape.

[0614] (See Example 2 for reference)

[0615] In the bag body of the eighth embodiment, a sealing sheet 180 is installed in the main body of the bag body. However, it is also possible to set the bag body and the sealing sheet 180 together when the sealing sheet 180 is removed from the main body of the bag body (see Example 2). In Example 2, the sealing sheet 180 may also be pre-stored in the space of the bag body.

[0616] [9. 9th Implementation]

[0617] The bag body 10 of the ninth embodiment has a bag body fragility portion 190 as shown below in any one of the bag bodies 10 of the first to eighth embodiments.

[0618] In the bag body 10 of the eighth embodiment, the main body 20 has a bottom 22 and a peripheral wall portion 21 connected to the bottom 22. The peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of facing wall portions. The main body 20 forms a space portion 23 enclosed by the bottom 22 and the peripheral wall portion 21 that can hold contents, and an opening portion 24 for inserting the contents into the space portion 23. In the bag body 10 of the eighth embodiment, as... Figure 38 A to Figure 38 As shown in Figure B, a bag-body fragility portion 190 is formed in the peripheral wall portion 21. Furthermore, the structure of the main body 20 (peripheral wall portion 21 and bottom portion 22, etc.) is the same as described in the first to eighth embodiments, therefore detailed descriptions are omitted. The figures showing an example of the ninth embodiment (…) Figure 38 For ease of explanation, the description of the position limiting component 30 has been omitted. Figure 38 This describes an embodiment in which a bag body fragility portion 190 is formed in the second wall portion 25B of the peripheral wall portion 21 of the main body, relative to the fifth embodiment.

[0619] (Vulnerable part of the bag body)

[0620] The bag body weakening portion is defined as a portion that is structurally weakened compared to a portion of the peripheral wall portion 21 that is different from the bag body weakening portion. Examples of bag body weakening portions include perforated structures and half-cut portions. Furthermore, from the viewpoint of maintaining the internal temperature of the bag body 10 as much as possible, the bag body weakening portion is preferably a half-cut portion. A half-cut portion can be defined as a structure that cuts into the peripheral wall portion 21 to a predetermined depth along the thickness direction of the peripheral wall portion 21. The depth of the "cut into the peripheral wall portion 21" forming the half-cut portion is not limited to half the thickness of the peripheral wall portion 21. The depth of the cut into the peripheral wall portion 21 can exceed half the thickness of the peripheral wall portion 21 or be less than half the thickness of the peripheral wall portion 21. The half-cut portion can be formed by cutting from the inner surface 21A of the peripheral wall portion 21 toward the outer surface 21B, or it can be formed by cutting from both the outer surface 21B and the inner surface 21A of the peripheral wall portion 21 in the thickness direction of the peripheral wall portion 21. The cut portion is preferably formed by cutting from the inner surface 21A of the peripheral wall portion 21 toward the outer surface 21B.

[0621] The fragile part of the bag body 190 Figure 38 In this example, it is formed in a U-shape, but this is just one example. The shape of the bag body fragility portion 190 is not particularly limited. In addition, by breaking the bag body fragility portion 190 to form the cover portion 191, or by lifting the cover portion 191 outward and breaking the bag body fragility portion 190, the space portion 23 of the bag body 10 can be exposed, and the contents stored in the space portion 23 can be taken out. Figure 38 A, Figure 38 In example B, by lifting the cover 191 outward in an upward direction, the fracture of the vulnerable portion 190 of the bag body develops, exposing the space portion 23 of the bag body 10. However, this is only one example of the cover 191. The cover 191 can also be configured such that the space portion 23 of the bag body 10 is exposed by lifting the cover 191 outward in a downward direction (lifting it downward), or the cover 191 can be configured such that the space portion 23 of the bag body 10 is exposed by lifting the cover 191 in a door-like manner.

[0622] The fragile part of the bag body 190 Figure 38 In this example, the 190 is formed on the second wall surface 25B, but this is just one example; it can also be formed on the first wall surface 25A, or on both the first wall surface 25A and the second wall surface 25B. Furthermore, the bag body fragility portion 190 can be formed on the entire surface of the peripheral wall portion 21. Alternatively, the bag body fragility portion 190 can be formed around the entire outer periphery of the peripheral wall portion 21.

[0623] (Film analysis)

[0624] From the viewpoint of easily displacing the cover 191, it is preferable to provide a pull tab 192 on the cover 191. The user pinches the pull tab 192 and pulls it outwards, thereby displacing (lifting) the cover 191 and causing the fragile portion 190 of the bag to break. Furthermore, as the cover 191 displaces and the fragile portion 190 of the bag breaks, the space 23 of the bag 10 is exposed, allowing the contents stored in the space 23 to be removed.

[0625] [10. Tenth Implementation]

[0626] [10-1 Composition]

[0627] In the bag body of the tenth embodiment, such as Figure 39 A, Figure 39 B Figure 39 As shown in C, similar to the fifth embodiment, any one of the bags in the first to fourth embodiments has a cover portion 120, and an adhesive placement portion 121 is provided in the cover portion 120. A cover portion through portion and a body through portion are formed on the cover portion and the body respectively, so that a gripping structure portion can be formed to function as a handle of the bag when the opening of the body is closed by the cover portion.

[0628] In the bag body of the tenth embodiment, the main body 20 has a bottom 22 and a peripheral wall portion 21 connected to the bottom 22. The peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of facing wall portions. The main body 20 forms a space portion 23 enclosed by the bottom 22 and the peripheral wall portion 21 that can hold contents, and an opening portion 24 for inserting the contents into the space portion 23. Figure 39 A to Figure 39 In example C, an example is shown where the peripheral wall portion 21 has a set of facing wall portions 25 and is provided with a cover portion 120 and an adhesive preparation portion 121.

[0629] Figure 39 In the example shown, for convenience, the pair of facing wall surfaces 25 are referred to as the first wall surface 25A and the second wall surface 25B. That is to say, the terms first wall surface 25A and second wall surface 25B are used only for ease of explanation, and the terms first wall surface 25A and second wall surface 25B can be used interchangeably.

[0630] The bag body of the tenth embodiment is similar to that described in the fifth embodiment, with a cover portion 120 and an adhesive placement portion 121 formed at the upper end of the first wall surface 25A. Additionally, as... Figure 39As shown in the example, in the bag body of the 10th embodiment, a release liner 122 is preferably provided in the same manner as described in the 5th embodiment. The configurations of the cover 120, the adhesive application section 121, and the release liner 122 are the same as described in the 5th embodiment, so detailed descriptions are omitted.

[0631] (The part through the cover and the part through the main body)

[0632] The bag body of the tenth embodiment has a cover through-hole 193 and a main body through-hole 195. Preferably, the cover through-hole 193 is formed on the inner side compared to the outer periphery of the area where the adhesive placement part 121 is formed. Figure 39 In this example, the through-hole 193 of the cover portion is formed by a rectangular through-hole in the cover portion 120. When a release liner 122 is mounted on the cover portion 120, the through-hole 193 of the cover portion is preferably formed to avoid the release liner 122.

[0633] The main body through portion 195 is formed at a predetermined position on the peripheral wall portion 21 of the main body 20. The main body through portion 195 is formed such that, when the opening portion 24 is covered by the cover portion 120, it is positioned opposite to the cover portion through portion 193. Figure 39 In this example, the main body through-hole 195 is formed by a rectangular through-hole in the peripheral wall portion 21. The main body through-hole 195 is formed on either the first wall portion 25A or the second wall portion 25B, and the formation positions of the main body through-hole 195 on the first wall portion 25A and the second wall portion 25B are preferably substantially aligned.

[0634] (Holding the structural part)

[0635] When the upper end of the second wall surface is covered by the cover 120 (in the case where the opening 24 is sealed by covering the upper end of the second wall surface with the cover 120), the position of the cover through-hole 193 is substantially aligned with the position where the main body through-hole 195 of the second wall surface 25B is formed. At this time, the positions of the cover through-hole 193, the main body through-hole 195 of the second wall surface 25B, and the main body through-hole 195 of the first wall surface 25A are substantially aligned. By achieving this state, the gripping structure 194 is formed by the cover through-hole 193 and the main body through-hole 195.

[0636] [10-2 Functions and Effects]

[0637] According to the tenth embodiment, when the opening 24 is sealed by covering the upper end of the second wall surface with the cover 120, the user can use the grip structure 194 as a handle, thereby making it easy to carry the bag 10. The cover through portion 193 is made into a tough part by providing an adhesive placement portion 121 around it, thus making the grip structure 194 a sturdy structure.

[0638] [10-3 Variation Example]

[0639] (Variation Example 1)

[0640] In the bag body of the tenth embodiment, the shapes of the flap through-hole 193 and the main body through-hole 195 are not limited to rectangular shapes, but may also be other shapes (Modification 1). In the bag body 10 of Modification 1 of the tenth embodiment, for example, the shapes of the flap through-hole 193 and the main body through-hole 195 may be as follows: Figure 41 The shape shown is elliptical, but it can also be triangular, polygonal, or an indeterminate shape. Furthermore, the shapes of the cover through-hole 193 and the main body through-hole 195 can be the same or different.

[0641] (Variation Example 2)

[0642] In the bag body of the tenth embodiment, the cover through portion 193 can be as follows: Figures 42 to 47 The terrain shown is slit-shaped (Modification 2). In Modification 2, the cover through portion 193 is preferably formed in a shape similar to that of the grip structure reinforcement portion 196.

[0643] (Holding structure reinforcement)

[0644] The grip structure reinforcement 196 can be defined as having a structure in which the straight line connecting the two ends (positions HP1, HP2) of the long side of the cover through part 193 is used as the base end BP (base end BP of grip structure reinforcement 196), so that the entire grip structure reinforcement 196 can rotate from the base end to the front end TP (front end TP of grip structure reinforcement 196) about the base end BP as the rotation axis.

[0645] (The first example of a cover penetrating part and a gripping structure reinforcement part)

[0646] Figure 42 , Figure 43 , Figure 46 The first example described in section B is the cover penetration 193 and the grip reinforcement 196. In the first example, as... Figure 42 As shown, a cover through portion 193 is formed with the front end of the cover portion 120 facing upwards, such that the grip structure reinforcement portion 196 has its base end BP on the upper side and its front end TP on the lower side.

[0647] When the opening 24 is closed by covering the upper end of the second wall surface with the cover 120, as shown in the example Figure 43 A to Figure 43 As shown in Figure C, the gripping reinforcement 196 is positioned with the base end BP on the lower side and the front end TP on the upper side. Furthermore, Figure 46 As shown in B, in this case, the grip reinforcement 196 is preferably folded towards the space portion 23. When the grip reinforcement 196 is folded towards the space portion 23, it can pass through the main body through-hole 195 of the second wall portion 25B and the main body through-hole 195 of the first wall portion 25A, so that the front end TP of the grip reinforcement 196 is located on the outer surface side of the first wall portion 25A (the outer surface 21B side of the peripheral wall portion 21). Furthermore, by folding the front end TP of the grip reinforcement 196 back towards the outer surface side of the first wall portion 25A, the structure of the grip portion 194 can be strengthened. Additionally, in the grip reinforcement 196, it is preferable that an adhesive is provided on the portion facing the outer surface side of the first wall portion 25A when the front end TP of the grip reinforcement 196 is folded back towards the outer surface side of the first wall portion 25A. In this case, a predetermined portion of the front end TP side of the grip reinforcement 196 can be bonded to the outer surface side of the first wall surface 25A, thereby further strengthening the structure of the grip reinforcement 194. In addition, in this case, the exposure of the space 23 can be reduced by the grip reinforcement 196, thereby suppressing the risk of a third party or others improperly inserting their hand into the space 23.

[0648] (The second example of the cover penetrating part and the gripping structure reinforcement part)

[0649] Figure 44 , Figure 45 , Figure 46 Example A describes a second instance of a cover penetration 193 and a grip reinforcement 196. In this second instance, as... Figure 44 As shown, with the front end of the cover 120 facing upward, a cover through portion 193 is formed such that the grip reinforcement portion 196 has its base end BP on the lower side and its front end TP on the upper side.

[0650] In the second example, when the upper end of the second wall surface is covered by the cover 120, thus closing the opening 24, as follows: Figure 45 A to Figure 45 As shown in Figure C, the gripping reinforcement 196 is positioned with the base end BP on the upper side and the front end TP on the lower side. Furthermore, as... Figure 46As shown in B, in this case, the grip reinforcement 196 is preferably folded towards the space portion 23. Similar to the first example, with the front end TP of the grip reinforcement 196 passing through the main body penetration 195 of the second wall portion 25B and the main body penetration 195 of the first wall portion 25A, a predetermined portion of the front end TP of the grip reinforcement 196 is folded back towards the outer surface of the first wall portion 25A, thereby strengthening the structure of the grip reinforcement 194. Furthermore, unlike the first example, in the second example, the front end TP is folded upwards.

[0651] (The third example of a cover penetrating part and a gripping structure reinforcement part)

[0652] Figure 47 A, Figure 47 The third example described in section B is the cover penetration 193 and the grip reinforcement 196. In the third example, as... Figure 47 As shown in A, with the front end of the cover 120 facing upward, a cover through portion 193 is formed in such a way that a first grip structure reinforcement portion 196A is formed with the base end BP on the upper side and the front end TP on the lower side, and a second grip structure reinforcement portion 196B is formed with the base end BP on the upper side and the front end TP on the lower side. Figure 47 In example A, the through portion 193 of the cover is formed by an H-shaped slit structure. In example 3, as... Figure 47 As shown in B, a structure that strengthens the structure of the gripping structure 194 described in the first and second examples above can be formed, thereby achieving the desired effect.

[0653] [10-4 Reference Example]

[0654] In the bag body of the tenth embodiment, it is also possible to omit the position limiting member from each of the bag bodies in the first to fourth embodiments (that is, as shown in the example). Figure 31 As shown, the bag (consisting only of the main body) has the aforementioned cover penetration and main body penetration (reference example). In the reference example, as... Figure 32 As shown, an adhesive dispensing section 179 for sealing the opening may also be provided. The adhesive dispensing section 179 for sealing the opening is disposed on the upper end side of the peripheral wall portion 21 and on the inner surface 21A side of the peripheral wall portion 21. Examples of this adhesive dispensing section 179 include double-sided tape.

[0655] [11. 11th Embodiment]

[0656] [11-1 Composition]

[0657] The bag body in the 11th embodiment can be, for example, Figure 54 A, Figure 54B Figure 54 C and Figure 54 As shown in example D, in any one of the bag bodies of the first to tenth embodiments, a small piece portion 220 and a peelable portion 221 are provided. Figure 54 A to Figure 54 D is a diagram used to illustrate one embodiment of the 11th implementation.

[0658] The bag body of the 11th embodiment includes a main body 20. The main body 20 has a bottom 22 and a peripheral wall portion 21 connected to the bottom 22 at its periphery. The peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of facing wall surfaces. The main body 20 forms a space portion 23 enclosed by the bottom 22 and the peripheral wall portion 21, capable of holding contents, and an opening 24 for inserting the contents into the space portion 23. Figure 54 A to Figure 54 In example C, it is shown that the peripheral wall portion 21 has a set of facing wall portions 25 and is provided with a small piece portion 220 and a peelable portion 221.

[0659] Figure 54 In the example shown, for convenience, the pair of facing wall surfaces 25 in the peripheral wall portion 21 are referred to as the first wall surface 25A and the second wall surface 25B. That is to say, the terms first wall surface 25A and second wall surface 25B are only used for ease of explanation, and the terms first wall surface 25A and second wall surface 25B can be replaced.

[0660] (Small Film Section)

[0661] The bag body of the tenth embodiment has a small piece 220 in the peripheral wall portion 21. The small piece 220 has an adhesive attachment surface 223 on which an adhesive material is disposed. The adhesive attachment surface 223 of the small piece 220 is formed in the small piece 220, when the small piece 220 is rotated about the fixed end 226 of the small piece 220, in a region that is opposite to the inner surface of the wall surface 25 connected to the small piece 220 and opposite to the outer surface of the wall surface 25 facing the wall surface 25 connected to the small piece 220. Specifically, in Figure 54 A to Figure 54 In example D, the small piece 220 is formed as a portion extending from the first wall surface 25A. Furthermore, the adhesive adhesion surface 223 of the small piece 220 is formed in the small piece 220 in a region that can be opposite to the inner surface of the first wall surface 25A and opposite to the outer surface of the second wall surface 25B that faces the first wall surface 25A when the small piece 220 is rotated about the fixed end 226 of the small piece 220.

[0662] The small piece 220 has a fixed end 226 fixed to the peripheral wall 21 and a free end 227 that is displaceable relative to the peripheral wall 21. The small piece 220 is a part that can rotate the free end 227 at least about the fixed end 226 as an axis. Figure 54 In the example, the small piece 220 is formed as a portion having a fixed end 226 on a part of the upper end 225 of the first wall surface 25A and extending from the upper end 225 of the first wall surface 25A in a roughly rectangular shape, and the front end of the extended portion (the position of the front end side of the small piece 220) is provided as a free end 227. Figure 54 In this example, the small piece 220 is made of the same material as the first wall surface 25A, allowing it to be bent near the fixed end 226, enabling the small piece 220 to rotate about the fixed end 226 as an axis. The shape of the small piece 220 is approximately rectangular. However, Figure 54 The small portion shown is one example, and the small portion is not limited to this example. For example, the small portion 220 may be a portion extending from a predetermined position on the lower side of the first wall surface 25A compared to the upper end 225. In addition, the material of the small portion 220 may be different from the material of the first wall surface 25A.

[0663] The number of small parts 220 is not particularly limited. In addition, the shape of the small parts 220 is not particularly limited. Figure 54 A to Figure 54 In example D, two small pieces 220 are formed. When there are multiple small pieces 220, for example, the small pieces 220 can be offset towards the first wall surface 25A, that is, some small pieces 220 are located in the first wall surface 25A, and the other small pieces 220 are located in the second wall surface 25B.

[0664] (Adhesive adhesion surface)

[0665] A layer 222 made of adhesive material is formed in the small section 220, and the surface of layer 222 (the surface facing the opposite surface 224 of the small section) becomes the adhesive adhesion surface 223. Furthermore, the adhesive material forming layer 222 is not particularly limited, and examples include starch pastes and acrylic adhesives. Moreover, when the bag body 10 contains containers for juice and coffee, or when it contains food items such as fries and hamburgers, the adhesive material is preferably an adhesive suitable for food packaging.

[0666] (Removable chemical component)

[0667] The peelable portion 221 is configured to be freely peelable and bondable to the small piece portion 220. In the peelable portion 221, the surface formed by the region corresponding to the portion configured to be bondable to the small piece portion 220 is called the small piece opposing surface 224. Therefore, the peelable portion 221 has a small piece opposing surface 224. Furthermore, the small piece opposing surface 224 can be specified as a region pre-defined at a position opposite the adhesive adhesion surface 223.

[0668] In the bag body 10, the location where the peelable portion 221 is provided is a position that avoids the main body 20 from being exposed to the outside. By providing the peelable portion 221 at such a location, even when the opening 24 of the bag body 10 is closed using the small piece 220, it is possible to prevent the peelable portion 221 from being exposed to the outside of the bag body 10, thus maintaining a good appearance for the bag body 10. Furthermore, the position where the main body 20 is avoided from being exposed to the outside also includes, in the case where other components (components different from the main body 20) such as the patch material 251 (described later) are provided on the inner surface side of the main body 20 in the bag body 10, a location specified on the surface area of ​​such other components as the patch material 251. For example, such as Figure 62 As shown in C, at least a portion of at least one peelable portion 221 can also be disposed at the location of the patch material 251. Furthermore, Figure 62 The figure of C also serves as a diagram representing another example of the bag body of the modified example 5 of the 11th embodiment described later.

[0669] The peelable portion 221 has a release layer 228. Examples of materials that can be used for the release layer 228 include silicone resin. Furthermore, it is preferable to provide a barrier layer that prevents the compound forming the release layer 228 from penetrating between the release layer 228 and the component located on the back side of the release layer 228 (the component forming the wall surface 25). Also preferably, the surface of the release layer 228 has small sheet-like opposing surfaces 224.

[0670] (Restrictions on the opening of the opening based on the small segment and the peelable segment)

[0671] In bag 10, such as Figure 55 A to Figure 55 As shown in C, a structure can be formed in which the small piece 220 restricts the expansion of the opening 24 while the small piece 220 is detached from the peelable portion 221. That is, in the bag body 10, it is configured such that, while at least a portion of the small piece 220 is detached from the peelable portion 221 and bent, the small piece 220 can be bonded to the peripheral wall portion 21 in the region of the adhesive adhesion surface 223 in a manner that does not impede the movement of separating the first wall surface portion 25A from the second wall surface portion 25B. Figure 55 A to Figure 55 C is a diagram illustrating the process of forming a structure that restricts the enlargement of the opening 24 by the small piece 220.

[0672] The structure that restricts the enlargement of the opening 24 by the small piece 220 can be formed as follows. Regarding the bag body 10, from... Figure 54 The state shown in D, in which the small piece 220 is bonded to the peelable part 221, is set as follows: Figure 55 A and Figure 55 As shown in B, the small piece 220 is peeled off from the peelable part 221. Figure 55 A and Figure 55 In B, the small piece 220 is located directly above the wall surface 25, but this is an example.

[0673] Furthermore, so that the adhesive adhesion surface 223 is aligned with the wall surface 25 connected to the small piece 220 ( Figure 55 In C, the first wall surface 25A) faces the wall surface 25 ( Figure 55 The small piece 220 is bent (part of the small piece 220 is folded back) on the outer surface of the second wall surface 25B in section C. The adhesive attachment surface 223 of the small piece 220 is then bonded to the wall surface 25. At this time, movement that separates the first wall surface 25A and the second wall surface 25B (i.e., movement that separates the upper ends of the first wall surface 25A and the upper ends of the second wall surface 25B) is restricted. Here, the restriction on movement that separates the upper ends of the first wall surface 25A and the upper ends of the second wall surface 25B indicates that the expansion of the opening 24 is restricted.

[0674] [11-2 Functions and Effects]

[0675] In the past, to prevent unintentional enlargement of the opening in the bag, a separate sealing material was prepared on the peripheral wall and applied to seal the opening 24. However, the workability was reduced due to the need to prepare the separate sealing material and manage the inventory of the additional sealing material.

[0676] According to the 11th embodiment, the bag body is provided with a small piece 220 having an adhesive attachment surface 223 pre-formed in the main body 20, thereby eliminating the need for preparing separate sealing material and managing the inventory of sealing material. Furthermore, the adhesive attachment surface 223 of the small piece 220 is not only temporarily fixed by the peelable portion 221 (allowing for easy re-peeling and bonding), but also prevents the peelable portion 221 from being exposed to the outside of the bag body 10, thereby suppressing any degradation in appearance caused by unintentional exposure of the peelable portion 221.

[0677] [11-3 Variations]

[0678] (Variation Example 1)

[0679] In the bag body of the 11th embodiment, as follows Figure 56 As shown in A, it is also possible that an adhesive material sheet 230, which is formed independently of the peripheral wall portion 21, is adhered to the peripheral wall portion 21, and a portion of the adhesive material sheet 230 forms the small piece portion 220. This method is referred to as Variation 1 of the 11th embodiment. Figure 56 A is a cross-sectional view of the main part of the bag body in Modified Example 1 of the 11th embodiment. Figure 56 In section A, the bag body of variation 1 of the 11th embodiment is described as having the same characteristics as... Figure 55 The sectional view corresponding to the sectional view of A. Furthermore, Figure 56 In section A, for ease of explanation, the state in which the adhesive adhesion surface 223 is detached from the opposing surface 224 of the small piece is shown. In the unused state, it is preferable that the adhesive adhesion surface 223 and the opposing surface 224 of the small piece are bonded to each other.

[0680] Adhesive sheet 230 is used to attach a specified portion of one end of the material to the wall surface 25. Figure 56 In the example of A, the first wall surface 25A is bonded. A small piece is formed by extending from the wall surface 25 in a state where it is not bonded to the wall surface 25 that is the other end. The part of the adhesive material sheet 230 that is different from the small piece is called the fixing part 240. The fixing part 240 of the adhesive material sheet 230 and the bonding surface of the wall surface 25 are the same as the surface on which the adhesive adhesion surface 223 is formed. Furthermore, the "state where it is not bonded to the wall surface 25" referred to here means that the adhesive adhesion surface 223 of the small piece is not bonded to the wall surface 25 (the wall surface 25 facing the wall surface 25 that is bonded to a predetermined portion at one end). Figure 56 In example A, the outer surface of the second wall face (25B) is bonded. Figure 56 In this example, the adhesive material sheet 230 has an adhesive layer 222 on at least one side of the material sheet substrate sheet 231, and the portion where the layer 222 is formed is designated as a small piece 220. Furthermore, the adhesive material sheet 230 is bonded to the wall surface 25 in a defined area excluding the small piece 220, and in a region on the surface of the material sheet substrate sheet 231 that is the same side as the surface where the layer 222 is formed. Additionally, the upper end of the portion of the adhesive material sheet 230 bonded to the wall surface 25 preferably also serves as the fixing end 226 of the small piece 220.

[0681] The adhesive material sheet 230 is bonded to the side of the wall surface 25 opposite to the side where the peelable portion 221 is formed. Furthermore, when the bag body 10 is not in use (before the opening 24 is restricted from enlarging), the adhesive material sheet 230 is bent so that the adhesive surface 223 of the small piece 220 of the adhesive material sheet 230 faces the opposite side 224 of the small piece of the peelable portion 221, and the adhesive surface 223 is then easily peeled off and bonded to the other side.

[0682] (The formation of a state in which the expansion of opening 24 is restricted)

[0683] In a variation 1 of the 11th embodiment, the adhesive adhesion surface 223 is made to connect with the wall surface 25 (which is connected to the small piece 220) Figure 56 In A, the first wall surface 25A) faces the wall surface 25 ( Figure 56 In section A, the small piece 220 of the adhesive material sheet 230 is bent so that the outer surfaces of the second wall surface 25B face each other. The adhesive adhesion surface 223 of the small piece 220 is then bonded to the wall surface 25. At this time, the movement of the first wall surface 25A and the second wall surface 25B away from each other is hindered, thereby restricting the expansion of the opening 24.

[0684] (Variation Example 2)

[0685] In the bag body of the 11th embodiment, as follows Figure 56 As shown in B, the peelable portion 221 can also be formed from a release paper 235 that is formed independently of the peripheral wall portion 21. This method is referred to as Variation 2 of the 11th embodiment. Figure 56 B is a cross-sectional view of the main part of the bag body in Modification 1 of Embodiment 11. Figure 56 In section B, regarding the bag body of variant 1 of the 11th embodiment, it is described that... Figure 55 The sectional view corresponding to the sectional view of B. Furthermore, Figure 56 In section B, for ease of explanation, the state in which the adhesive adhesion surface 223 and the opposing surface 224 of the small piece are peeled off is shown. In the unused state, it is preferable that the adhesive adhesion surface 223 and the opposing surface 224 of the small piece are bonded to each other.

[0686] The release paper 235 has a structure in which a release layer 228 is formed on at least one side of the base paper 236. Small sheet-like opposing surfaces 224 are formed on the surface of the release layer 228. Figure 56The peelable portion 221 shown in B is formed by bonding the release paper 235 to the peripheral wall portion 21 with the side of the base paper 236 facing away from the forming surface of the release layer 228 towards the peripheral wall portion 21. However, the portion to which the release paper 235 is bonded is not limited to the peripheral wall portion 21. For example, in the case where the bag body is provided with a handle member as described later, the release paper 235 may also be bonded to the patch material that fixes the handle member to the bag body.

[0687] (Variation Example 3)

[0688] In the bag body of Modification 2 of Embodiment 11, as... Figure 57 A to Figure 57 As shown in D, alternatively, an adhesive material sheet 230, formed independently of the peripheral wall portion 21, can be adhered to the peripheral wall portion 21. A portion of the adhesive material sheet 230 forms the small piece portion 220, and a release paper 235 is used to adhere the side facing away from the small piece portion 224 to the adhesive material sheet 230. This method is referred to as Variation 3 of the 11th embodiment. Figure 57 A to Figure 57 D represents a diagram used to illustrate the main part of the bag body in Modification 1 of Embodiment 11.

[0689] The adhesive material sheet 230 is similar to that in modified example 1, with a specified portion on one end side being bonded to the wall surface 25 ( Figure 56 In example A, the first wall surface 25A) is bonded, and a small piece is formed by the portion that is not bonded to the wall surface 25 which is the other end and extends from the wall surface 25. However, the fixing part of the adhesive material sheet 230 in the surface of the adhesive material sheet 230 and the bonding surface of the wall surface 25 are different from the surface on which the adhesive adhesion surface 223 is formed.

[0690] Similar to Modified Example 2, the release paper 235 has a structure in which a release layer 228 is formed on at least one side of the base paper 236. However, the release paper 235 is bonded to the adhesive material sheet 230 with the side facing away from the surface where the release layer 228 is formed, i.e., the small piece facing surface 224. At this time, the release paper 235 is bonded to the surface of the adhesive material sheet 230 where the adhesive adhesion surface 223 is formed. Assuming that at least a portion of the release paper 235 is bonded to the bag body 10 via the adhesive material sheet 230, the release paper 235 forms a peelable portion 221.

[0691] When the bag body 10 is not in use (before the expansion of the opening 24 is restricted), similarly to the modified example 1, the adhesive material sheet 230 is bent so that the adhesive surface 223 of the small piece 220 of the adhesive material sheet 230 faces the opposing surface 224 of the small piece of the peelable part 221, and the adhesive surface 223 is peeled off and bonded to the adhesive surface 223 again.

[0692] (The formation of a state in which the expansion of opening 24 is restricted)

[0693] In the bag body 10 of the modified example 3 of the 11th embodiment, as follows: Figure 58 A to Figure 58 As shown in C, a structure can be formed in which the expansion of the opening 24 is restricted by the small piece 220 when the small piece 220 is peeled off from the peelable part 221.

[0694] In variation 3 of the 11th embodiment, such as Figure 58 As shown in C, the adhesive adhesion surface 223 is aligned with the wall surface 25 connected to the small piece 220. Figure 58 In C, the wall face 25 (the first wall face 25A) faces the wall face 25 ( Figure 56 In section C, the small piece 220 of the adhesive material sheet 230 is bent so that the outer surfaces of the second wall portion 25B face each other. Furthermore, the adhesive adhesion surface 223 of the small piece 220 is bonded to the wall portion 25. At this time, the movement of the first wall portion 25A and the second wall portion 25B away from each other is hindered, thereby restricting the expansion of the opening 24.

[0695] (Variation Example 4)

[0696] In the bag body of Modification 2 of Embodiment 11, as... Figure 59 A to Figure 59 As shown in D, alternatively, an adhesive material sheet 230, independently formed from the peripheral wall portion 21, can be bonded to the peripheral wall portion 21. A portion of the adhesive material sheet 230 forms the small piece portion 220. The adhesive material sheet is bonded to the outer surface of the peripheral wall portion, and the release paper is bonded to the inner surface of the peripheral wall portion. This method is referred to as Variation 4 of the 11th embodiment. Figure 59 A to Figure 59 D represents a diagram used to illustrate the main part of the bag body in Modification 1 of Embodiment 11.

[0697] In the bag body of Modification 4 of the 11th embodiment, the small piece 220 has the same structure as the small wall portion shown in Modification 1, and the peelable portion 221 has the same structure as the peelable portion shown in Modification 2, so detailed description is omitted.

[0698] Regarding the bag body 10 of the modified example 4 of the 11th embodiment, when the bag body 10 is not in use (before the state of the opening 24 being restricted is formed), similarly to the modified examples 1 and 2, the adhesive material sheet 230 is bent so that the adhesive surface 223 of the small piece 220 of the adhesive material sheet 230 faces the opposing surface 224 of the small piece of the peelable part 221, and the adhesive surface 223 is peeled off and bonded to the adhesive surface 223 again.

[0699] (The formation of a state in which the expansion of opening 24 is restricted)

[0700] In the bag body 10 of the modified example 4 of the 11th embodiment, as follows: Figure 60 A to Figure 60 As shown in C, a structure can be formed in which the expansion of the opening 24 is restricted by the small piece 220 when the small piece 220 is peeled off from the peelable part 221.

[0701] In variation 4 of the 11th embodiment, such as Figure 60 As shown in C, the adhesive adhesion surface 223 is aligned with the wall surface 25 connected to the small piece 220. Figure 60 In C, the wall face 25 (the first wall face 25A) faces the wall face 25 ( Figure 60 In section C, the small piece 220 of the adhesive material sheet 230 is bent so that the outer surfaces of the second wall portion 25B face each other. Furthermore, the adhesive adhesion surface 223 of the small piece 220 is bonded to the wall portion 25. At this time, the movement of the first wall portion 25A and the second wall portion 25B away from each other is hindered, thereby restricting the expansion of the opening 24.

[0702] (Variation Example 5)

[0703] In the bag body of the 11th embodiment, as follows Figure 61 A and Figure 61 As shown in B, a handle component 250 may also be provided. This method is referred to as Variation 5 of the 11th embodiment. Figure 61 A and Figure 61 B is a diagram illustrating one embodiment of variation 5 of the 11th embodiment. Figure 61In this example, by attaching patch material 251, used to secure the handle component 250 to the bag body 10, to the bag body 10 with adhesive or the like, the handle component 250 is secured to the inner surface of the bag body 10 (the inner surface of the body 20) at a position slightly lower than the upper end of the main body 20. However, it is not prohibited to secure the handle component 250 to the outer surface of the main body 20. The lower end of the handle component 250 is located slightly lower than the upper end of the main body 20, and a portion of the handle component 250 is located higher than the upper end of the main body 20. This portion of the handle component 250, located higher than the upper end of the main body 20, can function as a gripping part for the user to hold. The shape of the handle component 250 is not particularly limited. Figure 61 A, Figure 61 In example B, the handle component 250 is integrally formed in a U-shape, but this is just one example. In variation 5 of the 11th embodiment, in Figure 61 A, Figure 61 In example B, the release liner 235 may be bonded to the bag body 10 at a position avoiding the patch material 251, thereby forming the peelable portion 221 at a position avoiding the patch material 251. Figure 61 As shown in C, at least a portion of the release paper 235 can be bonded to the patch material 251, thereby forming at least a portion of the peelable portion 221 in the area overlapping with the patch material 251. Furthermore, at least a portion of the peelable portion 221 can be formed in the area overlapping with the patch material 251, which is also true when the peelable portion 221 is not formed by the release paper 235 and the release layer 228 is formed on the inner surface of the body 20.

[0704] (Variation Example 6)

[0705] In the bag body of the 11th embodiment, as follows Figure 62 A, Figure 62 As shown in B, a pull tab 241 capable of being pinched can also be provided extending from the free end 227 side of the small piece 220. This method is referred to as Variation 6 of the 11th embodiment. Figure 62 A and Figure 62Figure B is a diagram illustrating the main part of the bag body 10 of the modified example 6 of the 11th embodiment. The size and shape of the pull tab 241 extending from the free end 227 side of the small piece 220 are not particularly limited, but it is preferable to have a size and shape that allows a user to pinch it with their fingers. Furthermore, it is preferable to avoid forming an adhesive adhesion surface 223 on the pull tab 241. In the bag body of the 11th embodiment, by providing the pull tab 241, the possibility of the user coming into contact with the adhesive adhesion surface 223 can be suppressed, and the adhesive adhesion surface 223 of the small piece 220 can be bonded to the wall surface 25 in a manner that restricts the expansion of the opening of the bag body 10.

[0706] Furthermore, in the bag body 10 of the modified example 6 of the 11th embodiment, such as Figure 63 A, Figure 63 As shown in B, it can also be that at the base end of the pull tab 241, the portion on the free end 227 side of the small piece 220 (the portion corresponding to the pull tab 241) is folded back upwards. Figure 63 A, Figure 63 In section B, reference numeral 242 refers to the folded-back portion formed by folding the pull tab 241 back in the upward direction. Furthermore, when the folded-back portion 242 is formed and the front end of the pull tab 241 faces upward, as... Figure 63 A, Figure 63 As shown in B, preferably, at least a portion of the pull tab 241 is positioned above the upper end 225 of the peripheral wall portion 21 of the main body 20. This configuration makes the pull tab 241 easily visible from the outside of the bag body 10. Furthermore, Figure 63 A, Figure 63 Figure B is a diagram illustrating the main part of the bag body 10 of Modification 6 of the 11th Embodiment. Furthermore, Modification 6 of the 11th Embodiment can be applied to any one of the bag bodies 10 of Modifications 1 to 5 of the 11th Embodiment. For example, in... Figure 63 In section C, an example is shown where the configuration of Modification 6 of the 11th Embodiment is applicable to the bag body 10 of Modification 3 of the 11th Embodiment. Furthermore, Figure 63 In C, an example is shown where the front end of the pull tab 241 faces upward (an example where a folded-back portion 242 is formed).

[0707] [11-4 Reference Example]

[0708] In the 11th embodiment of the bag, the position limiting member may be omitted from the bag bodies of each of the 1st to 6th embodiments (that is, only the position limiting member is omitted). Figure 31 The bag body shown is provided with the small piece 220 and the peelable part 221 (reference example).

[0709] The bag body of the reference example of the 11th embodiment has a main body having a bottom and a peripheral wall portion continuous with the bottom at its periphery. The main body forms a space portion enclosed by the bottom and the peripheral wall portion capable of holding contents, and an opening portion for inserting the contents into the space portion. Furthermore, the peripheral wall portion has a first wall portion and a second wall portion as a set of facing wall portions. The peripheral wall portion also has a small piece portion with an adhesive attachment surface on which an adhesive material is disposed. The small piece portion has a fixed end fixed to the peripheral wall portion and a free end displaceable relative to the peripheral wall portion. The free end of the small piece portion can rotate at least about the fixed end. A peelable portion is provided, which has a small piece opposing surface at a position opposite to the adhesive attachment surface, and can be easily peeled back and bonded to the small piece portion again via the small piece opposing surface. In the bag body of the reference example of the 11th embodiment, the location where the peelable portion is provided is a location where the main body will avoid external exposure. Furthermore, the bag body is configured such that, with at least a portion of the small piece peeled from the peelable portion and bent, the small piece can be bonded to the peripheral wall portion in the area of ​​the adhesive adhesion surface without hindering movement that separates the first wall surface from the second wall surface.

[0710] In the case of the reference example, such as Figure 32 As shown, an adhesive dispensing section 179 for sealing the opening may also be provided. The adhesive dispensing section 179 for sealing the opening is disposed on the upper end side of the peripheral wall portion 21 and on the inner surface 21A side of the peripheral wall portion 21. Examples of this adhesive dispensing section 179 include double-sided tape.

[0711] [12. 12th Embodiment]

[0712] In the bag body of the 12th embodiment, such as Figure 65 A, Figure 65 As shown in example B, it is also possible that any one of the bag bodies in the first to tenth embodiments is provided with a surface bonding piece 253 and a peelable portion 254. Figure 65 A to Figure 65 Figure B is a diagram used to illustrate one embodiment of the 12th implementation.

[0713] The bag body of the 12th embodiment includes a main body 20. The main body 20 has a bottom 22 and a peripheral wall portion 21 connected to the bottom 22 at its periphery. The peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of facing wall surfaces. The main body 20 forms a space portion 23 enclosed by the bottom 22 and the peripheral wall portion 21, capable of holding contents, and an opening 24 for inserting the contents into the space portion 23. Figure 65 A to Figure 65 In example B, it is shown that the peripheral wall portion 21 has a set of facing wall portions 25 and is provided with an inner surface bonding piece 253 and a peelable portion 254.

[0714] Figure 65 In the example shown, for convenience, the pair of facing wall surfaces 25 in the peripheral wall portion 21 are referred to as the first wall surface 25A and the second wall surface 25B. That is to say, the terms first wall surface 25A and second wall surface 25B are only used for ease of explanation, and the terms first wall surface 25A and second wall surface 25B can be replaced.

[0715] The peelable portion 254 is the same as the peelable portion 221 described in the description of the 11th embodiment, and therefore a detailed description is omitted. Figure 65 In this example, the peelable portion 254 can be formed from a release paper 235 formed independently of the peripheral wall portion 21, as described in Modification 2 of the 11th embodiment. The release paper 235 has a structure in which a release layer 228 is formed on at least one side of the base paper 236. In the peelable portion 254, the side of the peelable portion 254 that faces the adhesive adhesion surface 223 is called the opposing surface 255.

[0716] (Inner surface bonding piece)

[0717] The bag body of the 12th embodiment has an inner surface bonding piece 253 attached to the peripheral wall portion 21. The inner surface bonding piece 253 is bonded to the inner surface side of the peripheral wall portion 21, and can be configured in the same way as the adhesive material sheet 230 described in the description of the 11th embodiment, except that it is always positioned from the upper end of the peripheral wall portion 21 to the lower side regardless of whether the opening portion 24 is open or closed (or from the upper end of each of the upper ends of the first wall portion 25A and the second wall portion 25B). Therefore, the configuration of the inner surface bonding piece 253 will continue to be described using the reference numerals and names used in the configuration of the adhesive material sheet 230. Figure 65 The example illustrates the following situation: as an inner surface bonding piece 253, similar to the adhesive material piece 230, a component with a structure having a layer 222 of adhesive on at least one side of the substrate piece 231 is used.

[0718] Therefore, the inner surface bonding piece 253 has an adhesive adhesion surface 223 on which an adhesive material is disposed. Furthermore, the portion of the inner surface bonding piece 253 in which the adhesive adhesion surface 223 is formed, such as... Figure 66 A to Figure 66As shown in D, this portion is formed in a region that is opposite to the inner surface of the second wall surface 25B when it rotates about the fixed end 253A of the inner surface bonding piece 253. The fixed end 253A is formed at approximately the end edge of the bonding area between the inner surface bonding piece 253 and the first wall surface 25A, and at the end edge near the area where the adhesive adhesion surface 223 is formed. Figure 66 A to Figure 66 Figure D is used to illustrate the operation of the inner surface bonding piece 253 when the inner surface bonding piece 253 is used to limit the expansion of the opening 24 of the bag body 10.

[0719] In the bag body of the 12th embodiment, such as Figure 65 As shown in Figure A, an inner surface bonding piece 253, independently formed from the peripheral wall portion 21, is bonded to the peripheral wall portion 21. When not in use, the adhesive adhesion surface 223 contacts the opposing surface 255. When in use, as... Figure 66 A to Figure 66 As shown in D, the adhesive adhesion surface 223 is separated from the opposing surface 255, and the adhesive adhesion surface 223 is bonded to the inner surface of the second wall surface 25B. This restricts the expansion of the opening 24.

[0720] Furthermore, the inner surface bonding piece 253 is preferably spaced at a predetermined interval between the fixed end 253A and the area where the adhesive adhesion surface 223 is formed. In this case, the interval between the fixed end 253A and the area where the adhesive adhesion surface 223 is formed is preferably greater than the thickness of the inner surface bonding piece 253. With this size, after the adhesive adhesion surface 223 is bonded to the inner surface of the second wall surface 25B, deformation such as slight lateral movement of the second wall surface 25B and the first wall surface 25A near the opening 24 of the bag body 10 can be expected to correct any misalignment between the second wall surface 25B and the first wall surface 25A.

[0721] [12-2 Reference Example]

[0722] In the bag body of the 12th embodiment, it is also possible to omit the position limiting member from the bag bodies of each of the 1st to 10th embodiments (that is, as shown in the example). Figure 31 The bag shown (consisting only of the main body) is provided with the aforementioned inner surface bonding piece 253 and peelable part 254 (reference example).

[0723] [13. 13th Embodiment]

[0724] [13-1 Composition]

[0725] In the bag body of the 13th embodiment, such as Figure 67 A and Figure 67As shown in example B, in any one of the bag bodies of the first to the twelfth embodiments, the main body 20 is composed of a bending structure 260, and a side end adhesive portion 261 is provided on the bending structure 260 in a manner that satisfies specific conditions. Figure 67 A to Figure 67 Figure B is a diagram used to illustrate one embodiment of the 13th implementation.

[0726] The bag body of the 13th embodiment includes a main body 20. The main body 20 has a bottom 22 and a peripheral wall portion 21 connected to the bottom 22 at its periphery. The peripheral wall portion 21 has a set of facing wall surfaces 25 and a set of facing side wall surfaces 26. In the peripheral wall portion, each wall surface is continuous with the side wall surface at its side edge. Figure 67 In example A, the peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of facing wall portions 25. The main body 20 forms a space portion 23 enclosed by the bottom 22 and the peripheral wall portion 21, capable of receiving contents, and an opening 24 for inserting the contents into the space portion 23. Figure 67 A to Figure 67 In example B, it is shown that the peripheral wall portion 21 has a set of facing wall portions 25.

[0727] Figure 67 For convenience, the two opposing wall surfaces 25 shown in the example are referred to as the first wall surface 25A and the second wall surface 25B. In other words, the terms first wall surface 25A and second wall surface 25B are used only for ease of explanation and can be replaced with other terms.

[0728] The main body 20 has at least one corner portion on the inner surface of the peripheral wall portion 21 that extends from the bottom toward the opening. Figure 67 In the example of the main body 20 shown in A, there are four boundary positions between the wall surface 25 and the side wall surface 26, and a corner 28 is formed at each boundary position.

[0729] in addition, Figure 67 In this example, a position limiting member 30 is engaged at a predetermined position on the peripheral wall portion 21 of the main body 20. The main body 20 is composed of a bent structure 260, so the position limiting member 30 is engaged with the inner surface side of the bent structure 260.

[0730] (Bent structure)

[0731] The bent structure 260 constituting the main body 20 is a structure formed by bending the blank 500, and is defined as a structure that forms a structure corresponding to the peripheral wall portion 21 and the bottom portion 22. Here, the blank 500 is as follows: Figure 67The area shown in C can be defined as a sheet material formed in a shape corresponding to the main body 20. Additionally, the blank 500 is formed from a paper-like material. Figure 67 C is a top view illustrating one embodiment of the blank 500 that forms the bent structure 260, i.e., the blank that forms the main body 20. The paper material constituting the blank 500 can be any paper material suitable as the material of the main body 20. The material of the main body 20 is the same as the material of the main body 20 described in the first embodiment, and therefore a detailed description is omitted.

[0732] (Side-end adhesive part)

[0733] The bent structure 260 has a side end bonding portion 261 that bonds the first overlapping structure corresponding portion 560A and the second overlapping structure corresponding portion 560B, described later, to each other. The side end bonding portion 261 can be formed in the same way as the blank bonding portion 551 described in the first embodiment, and is formed by bonding them together with an adhesive or the like. Furthermore, the bent structure 260, as... Figure 67 As shown in Figure A, the first overlapping structure corresponding portion 560A and the second overlapping structure corresponding portion 560B are positioned in this order from the inner surface side of the bent structure 260, and the inner surface side of the first overlapping structure corresponding portion 560A is exposed to the "space inside the bent structure 260" side of the space portion 23 of the main body 20. The layout of the side end adhesive portion 261 is not particularly limited, and can be as follows: Figure 68 The terrain, like B, can be striped, grid-like, dotted, or... Figure 68 As shown in A, the surface to which one side is bonded is extended (one side forming).

[0734] (Burnt material)

[0735] Figure 67 In example C, the blank 500, when viewed from the thickness direction, has an upper edge 563, a lower edge 564, and a set of side edges 565 (lateral edge portions) as its outer peripheral portion 562. The blank 500 includes a portion corresponding to the peripheral wall portion 21 (peripheral wall corresponding portion 502) and a portion corresponding to the bottom portion 22 (bottom corresponding portion 501).

[0736] The upper edge 563 of the billet is a portion of the outer peripheral edge 562 that forms the opening 24 when the main body 20 is formed by the bending structure 260. The lower edge 564 of the billet is a portion of the outer peripheral edge 562 formed on the opposite end side to the upper edge 563 of the billet. The lower edge 564 of the billet is located at the bottom 22 when the main body 20 is formed by the bending structure 260. A set of billet side ends 565 are portions of the outer peripheral edge that are connected to the upper edge 563 and the lower edge 564 of the billet, and the set of billet side ends 565 are located on opposite end sides. Figure 66 In C, the blank 500 is separated along its long side. The blank 500 has a first blank side end 565A and a second blank side end 565B as a set of blank side ends 565.

[0737] The blank 500 has an overlapping structure corresponding portion 560. The overlapping structure corresponding portion 560 is defined as a portion for joining a predetermined portion located inside the first blank side end 565A and a predetermined portion located inside the second blank side end 565B when a bent structure 260 is formed from the blank 500. As the overlapping structure corresponding portion 560, a first overlapping structure corresponding portion 560A and a second overlapping structure corresponding portion 560B are formed. Figure 67 In the blank 500 shown in C, the first overlapping structure corresponding portion 560A is determined by a predetermined portion on the side of the first blank side end 565A, and the second overlapping structure corresponding portion 560B is determined by a predetermined portion on the side of the second blank side end 565B.

[0738] The blank 500 has a first inward region 566A and a second inward region 566B. The first inward region 566A is defined as the region of the first overlapping structure corresponding portion 560A (the region of the surface of the first overlapping structure corresponding portion 560A) that faces inward toward the bending structure 260 (the side of the space portion 23 in the main body 20). The second inward region 566B is defined as the region of the second overlapping structure corresponding portion 560B (the region of the surface of the second overlapping structure corresponding portion 560B) that faces inward toward the bending structure 260 (the side of the space portion 23 in the main body 20).

[0739] At the specified position of the billet 500, such as Figure 67 C Figure 68 As shown in A, there is a predetermined relative region IVR. The predetermined relative region IVR is defined as a region in the blank 500 that is reserved for the position limiting member 30 to be positioned relative to (configured with).

[0740] The billet 500 specifies that at least one predetermined relative region IVR satisfies any one of the following three conditions A, B, and C.

[0741] Condition A: The predetermined relative area IVR is specified in the area that avoids the second inner area 566B.

[0742] Condition B: The predetermined relative region IVR is the area that is transversely cut at the corner corresponding to the curved position 567.

[0743] Condition C: One of the two side edge EGPs of the predetermined relative region IVR is located in the first inward region 566A.

[0744] Figure 67 In example C, the predetermined relative region IVR satisfies three conditions A, B, and C.

[0745] (The process of forming a bent structure from a blank)

[0746] The bending structure 260 can be formed, for example, by performing a process of bending the blank 500 and a process of bonding the specified parts as shown below. Figure 67 In the example shown in C, the blank 500 is composed of a rectangular sheet. A position limiting member 30 is bonded to a predetermined relative area IVR of the blank 500. Figure 67 In this process, the position limiting member 30 is made of a strip (strip) sheet, which is bonded to the blank 500 at both ends along its long side. The blank 500 with the position limiting member 30 bonded to it is then used to perform a bending process.

[0747] The blank 500 is defined as having a corner-corresponding bending position 567, and the position where the blank 500 is bent is specified at the portion corresponding to the corner 28. During the bending process of the blank 500, the blank 500 is bent at the corner-corresponding bending position. Furthermore, Figure 66 In the example, the corner corresponding to the bending position 567 is the portion determined by position PU1. Furthermore, Figure 67 The position PU2 shown in C is the position of the fold line, which is the folded part used to form the lining structure (the lining that can constitute the main lining part 29) when the bent structure 260 is viewed from the outer surface side.

[0748] Furthermore, the first overlapping structure corresponding portion 560A and the second overlapping structure corresponding portion 560B of the blank 500 overlap. At this time, the first overlapping structure corresponding portion 560A is arranged such that the second inward region 566B of the second overlapping structure corresponding portion 560B faces each other, so that the first inward region 566A of the first overlapping structure corresponding portion 560A is exposed.

[0749] In the process of bonding the blank 500, the first overlapping structure corresponding portion 560A and the second overlapping structure corresponding portion 560B of the blank 500 are bonded to each other, thereby forming a side end bonding portion 261. At this time, the blank 500 becomes a cylindrical structure 530. Furthermore, in the cylindrical structure 530, a position limiting member 30 is bonded to the first inward region 566A of the first overlapping structure corresponding portion 560A.

[0750] The portion of the cylindrical structure 530 corresponding to the bottom 22 (bottom corresponding part 501) is bent inward. Figure 67 C Figure 68 In example A, the bottom corresponding portion 501 has a first lower side portion and a second lower side portion. The first lower side portion is defined as a portion (part 501A) extending downward from the portion of the bottom corresponding portion 501 corresponding to the sidewall surface. There is one set (two) of the first lower side portions (part 501A). The second lower side portion is defined as a portion (part 501B) extending downward from the portion of the bottom corresponding portion 501 corresponding to the wall surface. There is one set (two) of the second lower side portions (part 501A). In the blank 500, the first lower side portion and the second lower side portion are arranged alternately.

[0751] The first lower portion (part 501A) of the cylindrical structure 530 is bent inward (towards the center of the cylindrical structure (arrow F2 direction)), and the second lower portion (part 501B) is also bent inward (towards the center of the cylindrical structure (arrow F2 direction)). At this time, the overlapping portions of parts 501A and 501B, and the overlapping portions of the two parts 501B, are bonded together with an adhesive or the like. In this case, a folded structure 27 is formed at the bottom 22. Additionally, reinforcing sheets or the like can be adhered to the bottom 22. Thus, a bent structure 260 is formed.

[0752] [13-2 Functions and Effects]

[0753] In conventional bags, side-end adhesive portions are formed at or near the corners. In this case, it is difficult to place a position-limiting component in the corner where the side-end adhesive portions are formed.

[0754] According to the bag body of the 13th embodiment, the positions of the side end adhesive portion and the position limiting member in the blank are set at specific positions, and the positions of the side end adhesive portion and the position limiting member are different. As a result, the side end adhesive portion can be formed and the position of the position limiting member is arranged at the corner.

[0755] [13-3 Variation Example]

[0756] (Variation Example 1)

[0757] Regarding the bag body 10 of the 13th embodiment, a specific blank 500 as shown below can also be used. That is, as a specific blank 500, such as Figure 68 A, Figure 68 As shown in B, the blanks for the adhesive portion corresponding to the adhesive portion A and the adhesive portion corresponding to the adhesive portion B can also be specified in such a way that at least a portion of the adhesive portion corresponding to the adhesive portion A also serves as at least a portion of the adhesive portion corresponding to the adhesive portion B. Here, in the blank 500, the adhesive portion corresponding to the adhesive portion A is the portion in the first overlapping structure corresponding portion 560A that corresponds to the side-end adhesive portion 261. Figure 68 A to Figure 68 The portion B, indicated by reference numeral 571 in the drawing (the shaded portion) is the part of the blank 500 that corresponds to the portion that joins the position limiting member 30 and the bending structure 260 (the portion 572 opposite to the joining allowance portion 32). This arrangement having both the adhesive portion A and the adhesive portion B is referred to as Variation 1 of the 13th Embodiment. Figure 68 A, Figure 68 B is a top view illustrating an embodiment of the blank 500 formed for the bag body 10 of a modified example 1 of the 13th embodiment.

[0758] According to a variation of the 13th embodiment, when performing a process of bonding the first overlapping structure corresponding part and the second overlapping structure corresponding part to form a side end bonding part by using heat sealing or the like, it is also possible to heat seal the part where the position limiting member is joined to the blank, thereby forming a state in which the part where the position limiting member and the blank are joined more firmly.

[0759] The corresponding portions A and B of the adhesive portion can be completely repeated, or a portion of the corresponding portion B can be included in the corresponding portion A. It is also possible for the corresponding portion A to include the corresponding portion B. Furthermore, these provisions do not prohibit the corresponding portion A from being included in the corresponding portion B.

[0760] Figure 68 In B, the side-end adhesive portion 261 is composed of multiple linear adhesive portions arranged in a stripe pattern. In this example, the adhesive portion corresponding to portion A in the blank 500 is determined by portions corresponding to the multiple linear adhesive portions, and the adhesive portion corresponding to portion B is determined by a portion of a single linear adhesive portion. Furthermore, in variation 1 of the 13th embodiment, as... Figure 68 As shown in C, separation of the adhesive portion A and the adhesive portion B in the bag body 10 of the 13th embodiment is not prohibited.

[0761] (Variation Example 2)

[0762] Regarding the bag body 10 of the 13th embodiment, as follows Figure 69 A, Figure 69 As shown in example B, a handle structure 252 may also be provided on the main body 20. This method is referred to as variation 2 of the 13th embodiment. Figure 69 A is a top view illustrating an embodiment of the bag body 10 of Modified Example 2 of the 13th embodiment. Figure 69 The description of B is a top view of an embodiment of the blank 500 formed by the bag body 10 of the modified example 2 of the 13th embodiment.

[0763] The configuration of having a handle structure 252 on the main body 20 can be achieved by bonding the handle structure 252 to the bending structure 260.

[0764] The handle structure 252 represents the structure in which the handle component 250 and the patch material 251 are combined. The handle component 250 and the patch material 251 can be described using the same content as in Variation 5 of the 11th embodiment, therefore detailed description is omitted. In terms of the appearance of the main body 20, the handle component 250 is arranged such that it is partially exposed upwards from the upper end of the peripheral wall portion 21, and the patch material 251 is arranged such that it covers the portion of the handle component 250 opposite to the peripheral wall portion 21. The patch material 251 is bonded to both the peripheral wall portion 21 and the handle component 250. The handle component 250 is also bonded relative to both the peripheral wall portion 21 and the patch material 251.

[0765] (Burnt material)

[0766] The blank 500 formed for the bag body 10 of the modified example 2 of the 13th embodiment is as follows: Figure 69 As shown in C, a specific area is designated as the handle bonding area 575. Figure 69 C is a top view showing an example of the blank 500 formed for the bag body 10 of the modified example 2 of the 13th embodiment. The handle bonding area 575 represents the area in the blank 500 corresponding to the area where the handle structure 252 is bonded. In the blank 500, the handle bonding area 575 is preferably defined as an area that will not transversely cut the end ELN of the blank side end 565 when the structure 260 is bent. In the bag body 10 of the modified example 2 of the 13th embodiment, even assuming that the handle structures 252 are respectively provided on a set of wall surfaces 25, and the position limiting member 30 is provided on all corners 28 (bag body 10 as shown) Figure 69 In the case where the terrain is box-shaped, a bending structure 260 can also be formed by bending the blank 500 in such a state that all corners of the corners 28 formed at the four corners are provided with position limiting members 30. The position limiting members 30 and the handle structure 252 are pre-engaged with the blank 500 at the specified positions.

[0767] With the handle bonding area 575 defined in this way, the handle structure 252 is bonded to the designated position in the blank state 500. In this case, the necessity of performing the process of placing the handle structure 252 in the designated position after forming the bent structure 260 can be eliminated, thereby simplifying the manufacturing process of the bag body 10.

[0768] [14. 14th Embodiment]

[0769] [14-1 Composition]

[0770] In the bag body of the 14th embodiment, such as Figure 70 A, Figure 70 B and Figure 70 As shown in example C, in any one of the first to thirteenth embodiments of the bag body, the main body 20 is composed of a bending structure 260, which is provided with an overlapping structure (bottom side overlapping structure 580) and a lower end fold-back portion 581, which will be described later. Figure 70 A to Figure 70 C is a diagram used to illustrate one embodiment of the 13th implementation.

[0771] The bag body of the 14th embodiment includes a main body 20. The main body 20 has a bottom 22 and a peripheral wall portion 21 connected to the bottom 22 at its periphery. The peripheral wall portion 21 has a set of facing wall surfaces 25 and a set of facing side wall surfaces 26. In the peripheral wall portion, each wall surface 25 is continuous with the side wall surface at its side edge. Figure 70 In example A, the peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of facing wall portions 25. The main body 20 forms a space portion 23 enclosed by the bottom 22 and the peripheral wall portion 21, capable of receiving contents, and an opening 24 for inserting the contents into the space portion 23. Figure 70 A to Figure 70 In example C, it is shown that the peripheral wall portion 21 has a set of facing wall portions 25.

[0772] Figure 70 For convenience, the two opposing wall surfaces 25 shown in the example are referred to as the first wall surface 25A and the second wall surface 25B. In other words, the terms first wall surface 25A and second wall surface 25B are used only for ease of explanation and can be replaced with other terms.

[0773] The main body 20 has at least one corner portion on the inner surface of the peripheral wall portion 21 that extends from the bottom toward the opening. Figure 70In the example of the main body 20 shown in A, there are four boundary positions between the wall surface 25 and the side wall surface 26, and a corner 28 is formed at each boundary position.

[0774] in addition, Figure 70 In this example, a position limiting member 30 is engaged at a predetermined position on the peripheral wall portion 21 of the main body 20. The main body 20 is composed of a bent structure 260, so the position limiting member 30 is engaged with the inner surface side of the bent structure 260.

[0775] (Bent structure)

[0776] The bending structure 260 constituting the main body 20 is a structure formed by bending the blank 500, and is defined as a structure that forms a structure corresponding to the peripheral wall portion 21 and the bottom portion 22. The blank 500 can be defined as a sheet material formed into a shape corresponding to the main body 20. In addition, the blank 500 is formed of paper material. The paper material constituting the blank 500 can be any paper material that can be used as the material of the main body 20. The material of the main body 20 is the same as the material of the main body 20 described in the first embodiment, and therefore a detailed description is omitted. Figure 70 In this example, the bending structure 260 has a side-end bonding portion 261. The side-end bonding portion 261 is a structural part that bonds a group of blank side ends 565 of the blank 500. The layout of the side-end bonding portion 261 is not particularly limited. Specifically, the side-end bonding portion 261 can be constructed in the same manner as the side-end bonding portion described in the 13th embodiment.

[0777] In the bag body 10 of the 14th embodiment, the bending structure 260 constituting the main body 20 has a first inward fold portion 582 and a second inward fold portion 583, and a bottom-side overlapping structure portion 580 formed as an overlapping structure portion corresponding to the bottom 22. In addition, in the bending structure 260, at least one of the set of second inward fold portions 583 is formed with a lower end fold-back portion 581, and at least a portion of the lower end fold-back portion 581 is disposed in the bottom-side overlapping structure portion 580 (located in the bottom-side overlapping structure portion 580).

[0778] (First inner fold)

[0779] The first inner fold 582 is defined as a portion having a structure formed by bending the first lower side portion (part 501A) of the blank 500 (described later) toward the inside of the bending structure 260. There are two (a set) first lower side portions in the blank 500, and a set of first inner fold portions 582 is formed in the bending structure.

[0780] (Second inner fold)

[0781] The second inner fold 583 is defined as a portion having a structure formed by bending the second lower side portion (part 501B) of the blank 500 (described later) toward the inside of the bending structure 260. Figure 70 In the example shown, the second inner fold 583 is a structure formed by bending the second lower side portion on the lower surface side of the first lower side portion (in a way that partially or entirely covers the lower surface side side of the first lower side portion). Two second lower side portions are provided in the blank 500 (a set), and a set of second inner fold portions 583 is formed in the bent structure 260.

[0782] (Diagonal bend)

[0783] Figure 70 In the example of the bent structure 260 shown, the second inner fold 583 forms a slanted fold 584. The slanted fold 584 is defined as a structure that folds the blank 500 back along a straight line extending obliquely relative to the lower edge of the lower edge of the blank 564 as a bending axis. The slanted fold 584 is formed in a manner that overlaps with the side end portion of the second inner fold 583. Figure 70 In this process, a slanted fold 584 is formed such that the side end portion of the second inner fold 583 is slanted. That is to say, Figure 70 In the example of the bag body 10 shown, the bending structure 260 is configured such that the width of the second inner fold 583 decreases from the base end of the second inner fold 583 toward the lower end of the lower edge of the blank 564. Furthermore, Figure 70 In this example, the second inner fold 583 is connected to the first inner fold 582 at the end edge of the oblique fold 584. That is, the outer end edge of the oblique fold 584 and the outer end edge of the first inner fold 582 are interconnected.

[0784] (Lower fold-back section)

[0785] At least one of the second inner folded portions 583 is provided with a lower end folded-back portion 581 that folds back a predetermined portion of the lower edge portion 564 of the blank. The lower end folded-back portion 581 may be a portion that folds back in the direction of the bending structure 260 (the folded-back portion to the inside) or a portion that folds back in the direction of the bending structure 260 (the folded-back portion to the outside). Figure 70 In the example shown, one of the two second inner folds 583 has a lower end fold-back portion 581, which is formed as a "fold-back portion toward the inner side of the bending structure 260". At least a portion of the lower end fold-back portion 581 is disposed in the bottom side overlapping structure portion 580 (located in the bottom side overlapping structure portion 580). Figure 70 In the example shown, the lower end fold-back portion 581 is integrally disposed on the bottom side overlapping structure portion 580.

[0786] (Bottom side overlapping structure)

[0787] The bottom side overlapping structure 580 is defined as an overlapping structure in which a group of the second inner folds 583 overlap each other when viewed from above the main body 20.

[0788] (Burnt material)

[0789] Figure 71 In example A, the blank 500, when viewed from the thickness direction, has an upper edge portion 563 and a lower edge portion 564 as its outer peripheral portion 562. In the blank 500, the outer peripheral portion 562 refers to a portion defined as the outer peripheral edge containing the blank 500 (a portion extending from a position slightly inward compared to the outer peripheral edge). A portion corresponding to the peripheral wall portion 21 (peripheral wall corresponding portion 502) and a portion corresponding to the bottom portion 22 (bottom corresponding portion 501) are defined. Furthermore, Figure 71 In the blank 500 shown in example A, there is a set of blank side ends 565. Figure 71 A is a top view showing an example of the blank 500 used to form the bag body 10 of the 13th embodiment. Furthermore, Figure 71 In section A, an example is shown where a blank with the configuration described in embodiment 13 is used. This is for... Figure 73 The same applies to A.

[0790] The upper edge portion 563, the lower edge portion 564, and a set of blank side ends 565 can be defined using the same definitions as described in the 13th embodiment. That is, the upper edge portion 563 is the portion of the outer peripheral edge portion 562 that forms the opening 24 when the main body 20 is formed by the bending structure 260. The lower edge portion 564 is the portion of the outer peripheral edge portion 562 formed on the opposite end side to the upper edge portion 563. The lower edge portion 564 is located at the bottom 22 when the main body 20 is formed by the bending structure 260. A set of blank side ends 565 are portions of the outer peripheral edge portion connected to the upper edge portion 563 and the lower edge portion 564, and the set of blank side ends 565 are located on opposite end sides. In the blank 500, there are a first blank side end 565A and a second blank side end 565 as a set of blank side ends 565.

[0791] In the blank 500, the bottom corresponding portion 501 has a first lower side portion and a second lower side portion. The first lower side portion is defined as a portion (part 501A) extending downward from the portion of the bottom corresponding portion 501 corresponding to the sidewall surface. There is one set (two) of the first lower side portions (part 501A). The second lower side portion is defined as a portion (part 501B) extending downward from the portion of the bottom corresponding portion 501 corresponding to the wall surface. There is one set (two) of the second lower side portions (part 501A). In the blank 500, the first lower side portion and the second lower side portion are arranged alternately.

[0792] (The process of forming a bent structure from a blank)

[0793] The bending structure 260 can be formed, for example, by performing a process of bending the blank 500 and a process of bonding the specified parts as shown below. Figure 71 In the example shown in A, the blank 500 is composed of a rectangular sheet. A position limiting member 30 is bonded to a predetermined position on the blank 500. Figure 71 In part A, the position limiting member 30 is made of a strip (strip) sheet, which is bonded to the blank 500 at both ends along its long side. The blank 500 with the position limiting member 30 bonded to it is then used to perform a bending process.

[0794] The blank 500 is defined as having a corner corresponding to the bending position 567, and the position where the blank 500 is bent is specified at the part corresponding to the corner 28. In the process of bending the blank 500, the blank 500 is bent at the corner corresponding to the bending position. Figure 71 (The arrow bends in the direction of arrow F1). Furthermore... Figure 71 In example A, the corner portion corresponds to the bending position 567. Similarly, as described in the 13th embodiment, the position corresponding to the corner portion 28 ( Figure 71 The location of A (PU1) is determined by this part. Furthermore, Figure 71 The position PU2 shown in A is the same as that described in the 13th embodiment.

[0795] Furthermore, in the process of bonding the blanks 500, the two blank side ends 565 of the blanks 500 overlap, and these blank side ends 565 are bonded to each other in a defined area of ​​the overlapping portion, thereby forming a side end bonding portion 261. At this time, as Figure 71 As shown in B, the blank 500 becomes a cylindrical structure 530. Figure 71 B is a perspective view illustrating an example of a cylindrical structure 530.

[0796] The portion of the cylindrical structure 530 corresponding to the bottom 22 (bottom corresponding portion 501) is as follows: Figure 71 B Figure 72A, Figure 72 As shown in B, it bends inward. Figure 72 A, Figure 72 B is a perspective view illustrating the process of bending the bottom corresponding part 501 for the cylindrical structure 530.

[0797] Figure 71 In example B, the first lower portion (part 501A) of the cylindrical structure 530 is bent inward (towards the center of the cylindrical structure 530 (arrow F2 direction)). A set of first lower portions are bent separately. At this time, as a structural part formed by bending a set of first lower portions, such as... Figure 72 As shown in A, a set of first inner fold portions 582 are formed. In addition, along with the formation of the first inner fold portions 582, the end edge portion of part 501B is bent obliquely to form an oblique fold portion 584.

[0798] Additionally, at least one of the second lower side portions (part 501B) folds back a specified portion of the lower side edge portion 564 of the billet. At this time, as... Figure 72 As shown in B, the folded-back portion forms the lower folded-back section 581.

[0799] Furthermore, the second lower side portion (part 501B) bends inward (towards the center of the cylindrical structure (arrow F2 direction)). A set of second lower side portions bend separately. At this time, as... Figure 70 As shown in C, a set of second inward folds 583 are formed as a structural part by bending a set of second lower side portions. At this time, a portion where portions 501A and 501B overlap and a portion where two portions 501B overlap are formed. The portion where the two portions 501B overlap (that is, the portion where a set of second inward folds 583 overlap each other) becomes the bottom side overlapping structural part 580. Figure 70 In example C, when viewed from above, the lower fold-back portion 581 is located on the bottom side of the overlapping portion 580 of the bent structure 260.

[0800] At least one of the overlapping portions of part 501A and part 501B, and the overlapping portions of two parts 501B (bottom-side overlapping structure 580), is bonded. Preferably, both the overlapping portions of part 501A and part 501B, and the overlapping portions of two parts 501B (bottom-side overlapping structure 580) are bonded. In this case, the bonding method can preferably be a method using adhesive or the like. As a result, the structure of the bent structure 260 is fixed, forming the portion that becomes the bottom 22. Thus, the bent structure 260 constituting the main body 20 is formed. Furthermore, it is not prohibited to also attach reinforcing sheets or the like to the portion that becomes the bottom 22.

[0801] [13-2 Functions and Effects]

[0802] In the past, there has been a requirement to improve the strength of the bottom in bag designs. Improving the strength of the bottom is important in that it is difficult for the bottom to break or deform, even when relatively heavy contents, such as beverage containers, are placed in the space of the bag.

[0803] According to the bag body of the 14th embodiment, in the bent structure 260 constituting the main body 20, a bottom-side overlapping structure 580 is formed at the portion corresponding to the bottom 22, and a lower end fold-back portion 581 is also formed. Therefore, the structure of the bottom 22 becomes more robust. Therefore, according to the bag body of the 14th embodiment, it is difficult for the bottom shape to collapse or the bottom to break.

[0804] [14-3 Variation Example]

[0805] (Variation Example 1)

[0806] In the bag body of the 14th embodiment, such as Figure 73 As shown in B, the second inner fold 583 may also omit the oblique fold 584. This method is referred to as Variation 1 of the 14th embodiment. Figure 73 B is a bottom view illustrating the bottom 22 in one embodiment of the bag body of the 14th embodiment, variation 1. The 14th embodiment, variation 1, is, for example, as shown in... Figure 73 As shown in Figure A, this is specifically achieved by separating the first lower side portion (part 501A) and the second lower side portion (part 501B) in the blank 500 through a cut 585 or the like. When the first lower side portion and the second lower side portion are separated, the first inner fold portion 582 and the second inner fold portion 583 are formed in the separated state.

[0807] [14-4 Reference Example]

[0808] In the bag body of the 14th embodiment, it is also possible to omit the position limiting member from the bag bodies of the 1st to 13th embodiments (that is, ...). Figure 31 As shown, in a bag consisting only of the main body, the aforementioned bent structure includes an overlapping section (described later) and a lower end fold-back section (described later) (reference example). In the reference example, as... Figure 32 As shown, an adhesive dispensing section 179 for sealing the opening may be provided. The adhesive dispensing section 179 for sealing the opening is disposed on the upper end side of the peripheral wall portion 21 and on the inner surface 21A side of the peripheral wall portion 21. Examples of this adhesive dispensing section 179 include double-sided tape.

[0809] [15. 15th Embodiment]

[0810] [15-1 Composition]

[0811] In the bag body of embodiment 15, such as Figure 74 A, Figure 74 B Figure 74 C and Figure 74 As shown in example D, in any one of the bag bodies of embodiments 1 to 14, at least in the second shape state ST2, the position limiting member 30 has a fold-back structure 590 in the limiting wall portion 31. Figure 74 A, Figure 74 B Figure 74 C and Figure 74 Figure D is a diagram illustrating one embodiment of the 15th embodiment. The other components besides the fold-back structure 590 can be the same as those in any of the bag bodies of the 1st to 14th embodiments. Therefore, the other components of the position limiting member 30 besides the fold-back structure 590 are omitted from the description.

[0812] (Return to structural section)

[0813] In the position limiting member 30, in the second shape state ST2, a fold-back structure 590 is formed in the limiting wall portion 31. The position and shape of the fold-back structure 590 are not particularly limited. Figure 74 In the example, in the second shape state ST2, a folded-back structure 590 is formed on the portion facing the wall surface 25. However, this does not prohibit the folded-back structure from being formed on the portion facing the side wall surface 26. It does not prohibit the folded-back structure 590 from being formed on both the portion facing the wall surface 25 and the portion facing the side wall surface 26. Furthermore, it does not prohibit the folded-back structure 590 from being formed in the range from the portion facing the side wall surface 26 to the portion facing the wall surface 25.

[0814] Position limiting component 30 is configured such that, in Figure 74 A and Figure 74 When the shape changes from the second shape state ST2 to the first shape state ST1 as shown in D, the folded structure 590 can change from a folded state to a released state. The folded state refers to, as... Figure 74 As shown in Figure A, a configuration is formed in which the folded-back structure 590 is folded. The folded-back structure 590 is configured such that the surfaces of the folded-back structure 590 located on the side of the small space portion 33 are opposite to each other within at least a portion of the area of ​​the position limiting member 30. The released state refers to, as... Figure 74 As shown in Figure D, the state in which the folded structure 590 is displaced toward the inside of the space section 23 ("released from the folded state" state). Figure 74 In A, the shape deformation of the folded state and the released state can be achieved by displacing the restricting wall 31 in the direction of arrow T.

[0815] Figure 74 In the example shown in C, the folded-back structure 590 has a broken line 591 extending in the vertical direction, but this is just one example. For example, the folded-back structure 590 may also have a broken line extending in the diagonal direction.

[0816] The number of fold-back structures 590 formed in a position limiting component 30 can be as follows: Figure 75 The example of A is one, but it can also form two or more. Figure 75 Example B describes that, as a position limiting member 30, three folded-back structural portions 590 are formed in the limiting wall portion 31. Figure 75 One of the four position limiting components 30 described herein has three folding structures 590 formed on it. Figure 75 A, Figure 75 B is a top view illustrating an example of the formation of the folded-back structural section 590. Furthermore, Figure 75 A, Figure 75 In section B, for ease of explanation, the thickness of the main body 20 and the position limiting component 30 is omitted. Additionally, the detailed structure of the main body 20 (e.g., the structure of the bottom 22) is also omitted. This is for... Figure 76 as well as Figure 77 The same applies.

[0817] exist Figure 74 In example A, the shape of the fold-back structure 590 in the position limiting component is a Z-shaped fold-back in the cross-section. However, this is just one example. The shape of the fold-back structure 590 can also be a meandering fold-back shape or a shape different from the Z-shaped fold-back shape.

[0818] When multiple fold-back structures 590 are formed in a position limiting member 30, the fold-back structures 590 can have the same shape or different shapes. Figure 74 In example A, two folded-back structural parts 590 are formed, and the shape of each folded-back structural part 590 is formed into a Z-shape facing opposite directions when viewed from above the bag body 10 (with the vertical direction as the line of sight).

[0819] Furthermore, the position limiting member 30, which has the folding structure 590, is in Figure 74 In example A, the position limiting member 30 is located at corner 28. This is an example, such as... Figure 73 As shown, the position limiting member with the folded-back structure 590 can also be as follows: Figure 76 A, Figure 76 Example B is a position limiting member 30 disposed in a position on the inner surface of the peripheral wall portion 21 other than the corner portion 28. Figure 76In section A, an example is shown where the position limiting member 30 has multiple folded-back structural parts 590. Figure 76 In section B, an example is shown where a folded-back structure 590 is formed in the position limiting member 30.

[0820] Position limiting component 30 Figure 74 In example A, the sheet is formed into a strip shape, but the shape of the sheet forming the position limiting member 30 is not limited to this. The shape of the sheet forming the position limiting member 30 can also be as follows: Figure 77 A to Figure 77 As shown in C, the sheet is formed in a fan shape. In this case, by forming the folded-back structure 590, it is also easy to set the position limiting member 30 to the second shape state. In addition, the shape of the sheet forming the position limiting member 30 can be such that, when the position limiting member 30 is set to the second shape state, the limiting wall portion 31 is a curved surface that is inclined upwards, which makes it easy to set the limiting wall portion 31 of the position limiting member 30 to have excellent matching with the shape of containers such as coffee cups. Figure 77 A is a top view representing an example of the position limiting component 30. Figure 77 B is used to illustrate that there is a Figure 77 A top view of the bag body 10 of the position limiting component 30 shown in Figure A. Figure 77 C represents Figure 77 A sectional view of the state of the H2-H2 line section in B.

[0821] [13-2 Functions and Effects]

[0822] Conventional bags are designed to hold relatively large items within a small space, serving as containers or other containers that can accommodate such items. In such cases, large-sized components are required as position-limiting parts, which limits the area on the inner surface of the peripheral wall where the position-limiting parts can be installed. Therefore, it is desirable to expand the small space without increasing the area on the inner surface of the peripheral wall where the position-limiting parts can be installed.

[0823] According to the bag body of the 15th embodiment, as the position limiting member transitions from the second shape state to the first shape state, the folded-back structure gradually disengages, thereby enabling the small space to expand compared to omitting the folded-back structure. Therefore, the small space can be expanded without enlarging the area on the inner surface of the peripheral wall where the position limiting member is provided.

[0824] Based on the description in this specification above, the technologies shown in (E1) to (E50) below can be appreciated.

[0825] (E1) A bag body, wherein,

[0826] The device has a main body, a bottom, and a peripheral wall portion continuous with the bottom at its periphery. The main body forms a space enclosed by the bottom and the peripheral wall portion, capable of receiving contents, and an opening for inserting the contents into the space.

[0827] The main body is provided with a position limiting member, which has a limiting wall portion that restricts the movement of the contents inside the space.

[0828] The position limiting component engages at least with the inner surface of the peripheral wall portion.

[0829] When the contents are placed in the space in such a way that the movement is restricted by the restricting wall, the surface of the restricting wall that faces the contents is designated as the opposing surface. In this case, the restricting wall is configured to be able to form at least a first shape state in which the opposing surface forms a concave surface, and a second shape state different from the first shape state.

[0830] (E2) The bag body as described in (E1) above, wherein,

[0831] The inner surface of the peripheral wall portion has at least one corner portion extending from the bottom toward the opening.
