Description

Technical Field

[0001] The utility model relates to a bag body. Background Art

[0002] In the past, in various stores such as convenience stores and fast food restaurants, the practice of placing beverages and foods such as drinks in simple containers or wrapping them in wrapping paper and providing them to customers has been widely practiced. In addition, in recent years, in convenience stores, a sales method in which customers put beverages such as coffee in containers and purchase them has become widely popular. Moreover, in fast food restaurants, in addition to customers who eat and drink in the store, customers who accept take-out services such as picking up goods from the store and eating and drinking at places outside the store, and customers who accept delivery services such as store staff delivering goods to pre-designated places are also increasing.

[0003] Usually, when customers receive take-out service and delivery service, most of the goods are provided in the state of being contained in the bag. There have been various forms of bags in the past. As a bag, for example, a bag formed of paper material is commonly used. The bag generally has a storage space surrounded by a bottom surface and a side surface, which is used to store goods in the storage space (hereinafter, the items stored in the storage space are sometimes referred to as "contents"). (For example, patent documents 1 and 2). In the above-mentioned various stores, the behavior of storing the goods purchased by customers in the bag and providing them is widely carried out. However, when using the bag disclosed by these patent documents 1 and 2 to provide goods, there is a concern that the store clerk will carelessly store the goods in the storage space of the bag and provide them to the customer. In this case, especially when the container contained in the bag is provided to the customer in a state that it is easy to tip over in the bag, there is a concern that the customer may have a situation where the drink splashes out of the container in the bag before eating. In order to solve such a situation, the following behavior is being taken: the cup holder disclosed in patent document 3 shown below is stored in the bag, and the goods are provided to the customer in a state where the container is held by the cup holder.

[0004] Prior art literature

[0005] Patent Literature

[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 is formed with an opening for holding a container, so that the container is held by inserting the lower portion of the cup holder from above. However, in the case of a busy store, there is a concern that the container containing the beverage is not firmly inserted into the cup holder and provided to the customer. Therefore, even by using the cup holder disclosed in Patent Document 3, it is difficult to reliably solve the hidden danger of the container in the bag body tipping over. In addition, the cup holder is usually formed independently from the bag body. Therefore, when providing beverages to customers, not only is it necessary to accommodate the container in the bag body, but there is also another process of accommodating the cup holder in the bag body before the container. Therefore, there is a concern that it will be very troublesome and the operation will become troublesome.

[0010] In addition, even if the container is held by the cup holder in the bag, there is a concern that the container in the bag may fall off the cup holder due to the shaking of the customer when taking the product out or the store clerk delivering the product. In addition, there is a concern that the container in the bag may be shaken while being held by the cup holder, causing the beverage in the container to splash out of the container. Usually, when the container is housed in the bag, the lid is fitted with the peripheral edge formed on the container to be sealed, but it is difficult to eliminate the risk of the beverage leaking from the gap between the container and the lid due to the shaking of the container.

[0011] In addition, the cup holder disclosed in Patent Document 3 needs to have the strength to hold the container inserted into the opening as much as possible, and therefore, thick paper, corrugated paper, and a molded body based on a pulp molding process that have toughness are mostly used. In addition, the cup holder mostly has a three-dimensional shape in order to hold the container, but the storage performance needs to be considered during circulation and storage in the store, and therefore it needs to be a somewhat flat form. Therefore, the cup holder is required to be deformed from a flat shape to a three-dimensional shape through a simple operation. As mentioned above, the cup holder is usually formed of a strong paper material such as thick paper, and therefore, in order to deform from a flat shape to a three-dimensional shape through a simple operation, it is necessary to pre-form a fold or crease at the deformed portion. However, if such a fold is formed, in the case where a beverage leaks from the container, there is a concern that the leaked beverage will pass through the fold of the cup holder and wet the bag body.

[0012] The present invention is made in view of such problems, and its object is to provide a bag body that can simply and stably hold a container through simple operation, and can significantly reduce the wetting of the bag body by the liquid even when the beverage leaks from the container.

The description is based on these. Figure 1 Other drawings ( Figures 2 to 47 ) is the same. Figures 1 to 47 The relative size ratios such as the sizes shown in the respective drawings are described for the sake of convenience and do not limit the actual size ratios.

[0257] [1 First Implementation Method]

[0258] [1-1 Composition]

[0259] The bag body 10 of the first embodiment includes a main body 20, which is formed into a container ( Figure 2 , Figure 3 The container 200 (contents) is contained in the space 23 and the opening 24 is inserted into the storage space (space 23).

[0260] (main body)

[0261] The main body 20 has a bottom 22 and a peripheral wall portion 21 which is a wall portion continuous at the periphery of the bottom. In the main body, a housing space (hereinafter referred to as a space portion 23) is formed as a space surrounded by the peripheral wall portion continuous at the periphery of the bottom.

[0262] (Material of the main body)

[0263] The material of the main body 20 is not particularly limited, but is preferably formed of a paper material having fibers from the viewpoint of hygroscopicity and the viewpoint of reducing environmental burden. Figure 1 A to Figure 1In the example of C, the main body 20 is formed of a paper material. In addition to the so-called paper made by bonding plant fibers and other fibers, paper materials can also include chemical fiber paper, synthetic paper, water-resistant paper, coated paper, substitute paper, parchment, wool paper, glass fiber paper, stone paper, ceramic paper, etc. Paper materials can be recycled paper or non-recycled paper. In addition, as long as the main body 20 has a paper material, it is not prohibited to use non-paper materials in combination. As non-paper materials, cloth materials (woven materials and non-woven fabric materials) and the like can be cited. As non-woven fabric materials, for example, the so-called air-laid sheet formed into a sheet by combining fiber raw materials opened by air flow after fiber accumulation, pulp materials, natural fiber materials, synthetic fibers and other fiber non-woven fabrics can be cited. As the material of the main body 20, a material composed of a paper material and a non-paper material can also be used. As a non-paper material, it can be a resin composed of a resin material such as a synthetic resin and a natural resin. As an example of a combination of paper material and resin, the main body 20 may have a structure in which a resin sheet is laminated on at least one surface of the paper material. However, as described above, from the perspective of reducing environmental burden, it is preferred that the resin sheet be omitted (composed only of paper material) as the material of the main body 20.

[0264] (Surrounding wall)

[0265] The peripheral wall portion 21 stands up from the peripheral edge of the bottom 22. In addition, the peripheral wall portion is continuous at the peripheral edge of the bottom. The peripheral wall portion is formed in a cylindrical shape, and the space enclosed by the bottom and the peripheral wall portion described later forms a space portion. "The peripheral wall portion continuous at the peripheral edge of the bottom" includes any one of the cases where the bottom and the peripheral wall portion are formed by bending a single blank and the bottom and the peripheral wall portion are formed by docking different blanks. In other words, "the peripheral wall portion continuous at the peripheral edge of the bottom" means that a structure is formed in which the bottom and the peripheral wall portion are connected.

[0266] Figure 1 In the example of , the peripheral wall portion has a set of facing wall surface portions 25 and a set of facing side wall surface portions 26. In the peripheral wall portion, each wall surface portion is connected to the side wall surface portion at the side end edge of the wall surface portion.

[0267] (bottom)

[0268] The bottom portion 22 forms the bottom surface of the main body 20. The configuration of the bottom portion 22 is not particularly limited as long as it is a structure that can suppress the contents stored in the space portion from falling downward. Figure 1 In the example, Figure 5 A to Figure 5 As shown in C, the bottom is formed as a portion having a folding structure 27, and the folding structure 27 is formed by folding a portion (bottom corresponding portion 501) of the blank 500 corresponding to the bottom 22. In addition, Figure 5A is a diagram for explaining the bending of the blank 500 when the folded structure is formed. Figure 5 B. Figure 5 The example of C is an example of the bottom 22 and does not limit the structure of the bottom 22.

[0269] (Corner)

[0270] The 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 of the above, the corner portion 28 is formed so as to extend from the bottom portion toward the opening portion. The corner portion 28 is located at a boundary position between the wall surface portion and the side wall surface portion.

[0271] (Main body lining)

[0272] In the main body 20, preferably, when a set of wall portions 25 is set as a first wall portion 25A and a second wall portion 25B, a main body lining portion 29 for changing the distance between the first wall portion and the second wall portion is formed on the set of side wall portions 26. In this case, when the bag body 10 is not in use, the shape of the main body lining portion can be a shape such as a state where the distance between the first wall portion and the second wall portion is small (referred to as a contracted state). And when the bag body is in use, the shape of the main body lining portion can be a shape such as a state where the distance between the first wall portion and the second wall portion is large (referred to as a widened state). In this way, the bag body can be set to the widened state and the contracted state as needed, thereby enabling storage even in a narrow place when not in use, and ensuring a space portion for storing the contents when in use.

[0273] (Position restriction component)

[0274] The main body is provided with a position limiting component 30. The position limiting component 30 may be provided with one or more Figure 6 As shown in A, there are multiple ones. Figure 6 In the example of A, two position limiting components 30 are provided, each of which is independent and can change between a first shape state ST1 and a second shape state ST2 with respect to the state of the limiting wall portion 31 (movement of the movable portion of the limiting wall portion 31 in the direction of arrow T). Figure 6 In order to facilitate the description, the thickness of each component and the main body lining portion 29 are omitted. Figure 4 , Figure 7 The same is true.

[0275] The position restriction member 30 is joined to at least the inner surface of the peripheral wall portion. Figure 1 , Figure 2In the example of the present invention, a joining margin portion 32 joined to the peripheral wall portion 21 is formed at a side end of a restriction wall portion 31 described later, and the joining margin portion 32 is joined to the inner surface of the peripheral wall portion. Figure 1 , Figure 2 The example is an example, and the formation of the bonding margin portion 32 can also be avoided. Fig.11 As shown in FIG. 1B, the position limiting member 30 may be formed into a shape formed by connecting the sandwiched wall 50 and the limiting wall portion in an annular shape as described later in the second embodiment, and the sandwiched wall 50 and the inner surface of the peripheral wall portion may be joined. Figure 1 , Figure 2 As shown in FIG. 1 and FIG. 2 , when the peripheral wall portion has a wall portion 25 and a side wall portion 26, the position limiting member 30 is preferably joined to the wall portion and the side wall portion. In this case, when the corner portion 28 is formed at the boundary position between the wall portion and the side wall 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. Thus, when the limiting wall portion of the position limiting member is in the state as shown in FIG. Figure 2 After being deformed from the second shape state ST2 to the first shape state ST1 as shown in A, it is difficult to return from the first shape state ST1 to the second shape state ST2. As in the case of the joining margin portion 32, the portion of the limiting wall portion that is in a state of joining with other components and parts is called a fixed portion, and the portion of the limiting wall portion other than the fixed portion is called a movable portion. The movable portion can move between a position close to the fixed portion (first position) and a position (second position) separated from the fixed portion by a predetermined interval. The more the movable portion moves to a position (second position) further away from the fixed portion, the easier it is to form the first shape state, and the small space portion 33 described later can be formed to a size that can accommodate a container (paper cup, French fry container, etc.).

[0276] (Restriction wall)

[0277] The position restriction member 30 has a restriction wall portion. The restriction wall portion restricts movement of the contents in the space portion 23 (more preferably, horizontal movement of the contents in the small space portion 33).

[0278] In the position limiting component 30, the limiting wall portion 31 is configured to be able to form at least a first shape state ST1 in which the opposing surface 34 is formed into a concave surface, and a second shape state ST2 different from the first shape state. The opposing surface 34 is defined as follows. That is, when the content ( Figure 2 B. Figure 3In the case where the container 200 (in B, etc.) is arranged in the space portion 23, the surface of the limiting wall portion 31 facing the content is called the opposite surface 34. The case where the content is arranged in the space portion in a manner where the movement is restricted by the limiting wall portion means that when the bag body 10 is arranged such that the bottom portion faces the lower side and the opening portion faces the upper side, the horizontal movement of the content arranged in the space portion is restricted. In addition, the state where the movement is restricted by the limiting wall portion is achieved by forming the limiting wall portion into the second shape state ST2 when the content is arranged in the space portion.

[0279] The size of the limiting wall can be determined according to the size of the contents. For example, when the contents are containers 200 having a container body for beverages to be filled, the size of the limiting wall can be determined according to the outer diameter and outer shape of the container body 210.

[0280] In addition, the limiting wall is preferably formed to the vicinity of the upper end side of the container body. By forming it in this way, for example, when the container containing the beverage is held by the small space, it is easy to form a state in which the limiting wall is in contact with most of the outer peripheral surface of the container, thereby making it possible to make the limiting wall function as a cup sleeve, easily obtaining a heat insulation effect, improving the heat preservation property of the container or the cold preservation property of the container, and being able to maintain the temperature of the beverage in the container at a good temperature for a long time.

[0281] (Positional Relationship between Corner and Limiting Wall)

[0282] In addition, if Figure 1 As shown in the example of A, when the main body has a corner portion 28, it is preferred 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 at a position including the corner portion of the main body. In addition, in this case, when the movable portion moves from the first position to the second position, the small space portion formed in the state surrounded by the fixed portion and the movable portion can be ensured to be large, and a state in which relatively large contents can be easily held can be formed.

[0283] (1st shape state and 2nd shape state)

[0284] The state of the limiting wall portion is not particularly limited as long as the first shape state ST1 is a state in which the opposing surface 34 is formed into a concave surface, but Figure 2 In the example of A, the concave surface is a V-shaped surface (V-shaped in cross section). Figure 2The example of A is an example, and the concave surface can also be a U-shaped surface. For the first shape state ST1, in the state where the relative surface 34 forms a concave surface, it includes the case where the entire area of ​​the relative surface 34 becomes a concave surface, and also includes the case where a part of the relative surface 34 becomes a concave surface. However, from the viewpoint of ensuring the small space portion 33 in a sufficient size, the first shape state ST1 is preferably the case where substantially the entire area of ​​the relative surface 34 (the area of ​​the portion of the relative surface 34 corresponding to the above-mentioned movable portion) becomes a concave surface. In addition, as to whether the relative surface 34 is in a state where a concave surface is formed, it is possible to select two different points of the relative surface 34 and use the straight line passing through the two points as a reference (reference straight line ML) to confirm whether the relative surface 34 exists in the part on the side of the direction away from the peripheral wall portion 21 compared to the reference straight line ML when the bag body 10 is viewed from above, thereby making a judgment. When the facing surface 34 exists on the side away from the peripheral wall 21 relative to the reference straight line, it can be determined that “the side away from the peripheral wall 21 ” of the facing surface 34 forms a concave surface.

[0285] Regarding the state of the limiting wall portion, the second shape state ST2 is not particularly limited as long as it is a state different from the first shape state ST1. For example, the second shape state ST2 can be exemplified by a state in which the opposing surface 34 forms a convex surface. Figure 1 As shown in the example of A, the state where the convex surface becomes a mountain-shaped surface (a mountain-shaped cross section) can be cited. In addition, Figure 1 The example of A is an example, and the convex surface may also be a surface in the shape of the outer surface of a column, a spherical surface, etc. In addition, the second shape state ST2 is preferably a state in which a convex surface is formed on the opposite surface so that the limiting wall portion is along the inner surface 21A of the peripheral wall portion 21. In the case where the limiting wall portion is arranged in a manner covering the corner portion, the second shape state can be defined as a state in which the shape of the opposite surface in the limiting wall portion becomes a convex shape corresponding to the shape of the inner surface side of the corner portion. In addition, in the concept of the case in which the second shape state ST2 is a state different from the first shape state ST1, a state in which the opposite surface 34 is a flat surface is included.

[0286] (Material of position limiting parts)

[0287] The material of the position limiting component 30 is not particularly limited. The material of the position limiting component may be a paper material, or a resin or a metal. From the viewpoint of ease of disposal and the viewpoint of reducing the environmental burden, the position limiting component is preferably made of a paper material. In addition, the position limiting component is preferably waterproof. Therefore, it is more preferred that the position limiting component is made of a paper material and is waterproof. In the case where the content contained in the bag is a container containing a liquid, even if the liquid contained in the container adheres to the position limiting component, it is unlikely that the position limiting component will absorb the liquid and reduce the strength of the position limiting component.

[0288] (Positional Relationship between Contents and Position Restriction Components)

[0289] When the bag is not in use, the position limiting member provided on the inner surface side of the main body of the bag can set the limiting wall portion to the second shape state. When the bag is in use, for example, the user touches the limiting wall portion while setting the limiting wall portion from the second shape state to the first shape state. And the contents are inserted into the space of the bag in such a manner that the contents face the opposite surface. For example, in the case where the contents are a container containing a liquid, the outer peripheral surface of the container main body is inserted from the opening of the bag to the bottom of the space in such a manner that the opposite surface faces the outer peripheral surface of the container main body.

[0290] (Small Space Department)

[0291] In addition, in this specification, the "space portion surrounded by the main body and the position limiting member" and the "space portion where the limiting wall portion is set to the first shape state and the container is inserted in a manner that the container faces the opposite surface" in the space portion 23 of the bag body are referred to as the small space portion 33. And the portion forming the small space portion (the portion of the limiting wall portion and the peripheral wall portion) can function as a holding portion for limiting the movement of the contents such as the container and holding the contents. In this way, according to the utility model, the portion of the peripheral wall portion can play the function of limiting the movement of the contents.

[0292] When the container to be the content is arranged in the space as described above, it is preferable that there is a gap between at least a portion of the upper end of the limiting wall 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 out of the container, the splashed liquid can collide with the limiting wall, and it is difficult to generate a state in which the liquid splashes outward from the limiting wall. Therefore, when the bag body stores items other than containers, it is possible to suppress the occurrence of a state in which the liquid splashes onto the upper surface side of the items other than the container.

[0293] (Surface condition of position restriction component)

[0294] The position limiting member may be in a smooth state without the surface being processed with concavoconvex shapes, or may have a concavoconvex surface being processed with relief shapes. When the position limiting member has a concavoconvex surface, a higher heat insulation effect can be easily obtained.

[0295] (Blank)

[0296] Figure 1 In the bag body shown in the example of A, Figure 4 , Figure 5 As shown, the body 20 is formed from a blank 500 . Figure 4 , Figure 5 1 is a diagram for explaining the manufacturing process of the bag body 10. Figure 4 As shown in A, the blank 500 may be determined according to the shape and manufacturing method of the main body 20. Figure 4 In the example shown, the blank 500 is composed of a rectangular sheet. When the bag body 10 is manufactured, the position limiting member 30 is placed as shown in FIG. Figure 4 It is arranged at a predetermined position of the blank 500 as shown in B. Figure 4 As shown in C, the rectangular blank 500 is at a position corresponding to the corner portion 28 ( Figure 4 The blank 500 is bent in the direction of arrow F1 at the middle position PV, so that the bonding margin corresponding portion 550 of the side end of the blank 500 is bonded (the bonding portion formed at this time is referred to as the blank bonding portion 551). At this time, a cylindrical structure 530 is formed. The blank is pre-defined with a portion corresponding to the peripheral wall portion (the peripheral wall portion corresponding portion 502) and a portion corresponding to the bottom portion (the bottom portion 501). Figure 5 As shown in A, the portion of the tubular structure corresponding to the bottom (bottom corresponding portion 501) is bent inward. Figure 5 In the example of A, the portion (portion 501A) extending downwardly of the portion corresponding to the side wall surface in the bottom corresponding portion 501 is folded in the inward direction (the center direction of the cylindrical structure (the direction of arrow F2)), and the portion (portion 501B) extending downwardly of the portion corresponding to the wall surface is folded in the inward direction (the center direction of the cylindrical structure (the direction of arrow F2)). At this time, the portion where the portion 501A overlaps with the portion 501B and the portion where the two portions 501B overlap are bonded by an adhesive or the like. In this case, a folding structure 27 is formed at the bottom 22. In addition, a sealing material or the like for reinforcement may also be attached to the bottom 22.

[0297] [1-2 Functions and effects]

[0298] According to the bag body of the first embodiment, the operation of arranging the cup holder for stabilizing the position of the container outside the bag body can be omitted, and the container can be held simply and stably by a simple operation.

[0299] [1-3 Modification Example]

[0300] (Variant 1)

[0301] In the bag of the first embodiment, a waterproof layer may be formed on the upper surface side of the bottom (variant 1). In the case where a waterproof layer is provided on the upper surface side of the bottom as in variant 1, when a container for storing liquid is stored inside the bag, even if liquid splashes inside the bag, it is possible to more reliably prevent the liquid from penetrating into the bottom and wetting the lower surface side of the bottom of the bag, and preventing the bottom from being damaged and leaking the liquid from the bottom. Examples of the waterproof layer include: Figure 5 D shown in FIG. 3 , etc., as shown in FIG. 3 . In addition, the configuration in which a waterproof layer is provided on the upper surface side of the bottom can be realized by laying a waterproof sheet on the upper surface side of the bottom after the main body of the bag body is formed. In addition, the configuration in which a waterproof sheet is provided on the upper surface side of the bottom can be realized by laying a waterproof sheet on the portion corresponding to the bottom in the blank, and folding the blank with the waterproof sheet to form the main body. In addition, the configuration in which a waterproof layer is provided on the upper surface side of the bottom can also be realized by the following operation, that is, curing the coating film formed by applying a waterproof coating to the portion corresponding to the bottom in the blank, thereby forming a waterproof coating cured layer, and folding the blank with the waterproof sheet to form the main body.

[0302] (Variant 2)

[0303] In the bag body of the first embodiment, when the limiting wall portion is in the second shape state, as shown in FIG. Figure 6 As shown in B, at least one position limiting component is provided at a position where the corner portion is not covered by the limiting wall portion (variation 2). Figure 6 As shown in C, a small space portion 33 of a 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 for the limiting wall portion to return to the second shape state after the limiting wall portion is set to the first shape state when the bag body is used and before the container is inserted into the bag body, it is preferred that the position limiting member is provided in a manner that covers the position of the corner portion when the limiting wall portion is in the second shape state.

[0304] (Variant 3)

[0305] The bag body of the first embodiment may also be constructed as follows: Figure 7 A. Figure 7 As shown in B, there is one limiting wall portion, and the formation positions of the joining margin portions are set at multiple locations, thereby forming multiple small space portions 33.

[0306] (Variant 4)

[0307] In the bag body of the first embodiment, Figure 7 C. Figure 7 As shown in D, the size of the small space portion is not limited to the case where the size corresponds to the size of one container. The size of the small space portion may also be set to a size that can accommodate multiple containers. Figure 7 C. Figure 7 In the example shown in D, Figure 7 When a position limiting component is provided as in C, Figure 7 As shown in D, two containers can be arranged in the small space portion 33.

[0308] [2. Second Embodiment]

[0309] [2-1 Composition]

[0310] In the bag body of the second embodiment, Figure 8 , Fig. 9 As shown, the position limiting component 30 has a limiting wall portion 31 and a sandwiched wall 50. The bag body of the second embodiment has the same structure as the first embodiment except that the position limiting component is provided with the sandwiched wall 50. That is, the bag body of the second embodiment has a structure in which the position limiting component is provided with a sandwiched wall in the bag body of the first embodiment. Therefore, in the description of the second embodiment, a detailed description of other structures except the sandwiched wall of the position limiting component is omitted.

[0311] (Caught in the wall)

[0312] The position limiting component has a sandwiched wall 50 as described above, and when the bag body is viewed from above (when the vertical direction is the visual direction), the sandwiched wall is located between the peripheral wall portion of the main body and the limiting wall portion of the position limiting component. The sandwiched wall is at least joined to the inner surface of the peripheral wall portion. More specifically, the sandwiched wall is adhered to the peripheral wall portion in a state of surface contact with the inner surface of the peripheral wall portion, so that the sandwiched wall and the peripheral wall portion are bonded. If the portion where the sandwiched wall and the peripheral wall portion are bonded is set as a sandwiched wall bonding portion 51, the sandwiched wall bonding portion 51 is preferably formed locally in the area where the sandwiched wall and the peripheral wall portion face each other. And, preferably, a gap space portion 52 is formed between the sandwiched wall and the peripheral wall portion. By forming the gap space portion 52, a layer of gas such as air can be present between the sandwiched wall and the peripheral wall portion, thereby, it can be expected that the thermal insulation in the space portion (small space portion) formed by the sandwiched wall and the peripheral wall portion in the position limiting component is improved. Figure 8 , Fig. 9 A. Fig. 9 In the example of B, the sandwiched wall bonding portion is formed into a plurality of strips at intervals in the vertical direction of the peripheral wall portion. However, Figure 8 , Fig. 9The example is an example of the sandwiched wall bonding portion. It is not prohibited to form the sandwiched wall bonding portion entirely in the area where the sandwiched wall and the peripheral wall portion face each other. In addition, the layout of the sandwiched wall bonding portion can also be as follows Fig.12 A. Fig.12 For example, Fig.12 In A, the layout of the sandwich wall bonding part becomes Fig. 9 A. Fig. 9 The peripheral wall portion shown in B is spaced apart in the vertical direction and formed into a plurality of belt-like layouts. Fig.12 In B, the layout of the sandwiched wall bonding portion is an oblique grid-like layout formed by a plurality of strips that cross each other obliquely.

[0313] In the second embodiment, when the limiting wall portion is in the second shape state, it is preferable that Fig.10 As shown, the position of the lower end of the limiting wall portion 31 is located at a position above the position of the lower end of the sandwiched wall 50. By configuring in this way, the container can be arranged in the small space portion in a state where the position limiting component is firmly attached to the main body through the sandwiched wall, and thus the position limiting component can be expected to improve the structural reinforcement effect of the position limiting component and its vicinity when the container is arranged in the small space portion. In addition, from the viewpoint of further improving the structural reinforcement effect, it is preferred that the lower end 50A of the sandwiched wall 50 contacts the bottom 22.

[0314] (Blank)

[0315] In the bag body shown in the second embodiment, the position limiting member is arranged at a predetermined position of the blank 500 for forming the main body 20. The position limiting member is fixed to the blank by the sandwiched wall. Based on the blank with the position limiting member arranged in this way, the bag body can be obtained by bending at a predetermined position as described in the first embodiment.

[0316] [2-2 Functions and Effects]

[0317] According to the bag body of the second embodiment, the same effects as those of the first embodiment can be obtained.

[0318] [2-3 Modification Example]

[0319] (Variant 1)

[0320] According to the bag body of the second embodiment, the position restriction member is not limited to Fig.11 The limiting wall portion and the sandwiched wall shown in A are bonded to each other through the side edges. Fig.11 As shown in B, the position limiting component may be formed by continuously and integrally forming the limiting wall portion and the sandwiched wall. Fig.11In the example of B, the limiting wall portion 31 and the sandwiched wall 50 are continuously formed integrally, whereby the position limiting member is formed in a ring shape. Fig.11 In A, the joining margin portion 32 of the limiting wall portion 31 becomes a portion joined to the sandwiched wall 50 .

[0321] (Variant 2)

[0322] The bag body according to the second embodiment may also be provided with the structure shown in the modified example of the first embodiment.

[0323] [3. Implementation Method 3]

[0324] [3-1 Composition]

[0325] 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 Fig.13 As shown, the bag body of the second embodiment has a limiting wall portion 31, a sandwiched wall 50 and an inner bottom portion 80. The bag body of the second embodiment has the same structure as the first embodiment or the second embodiment except that the position limiting component is provided with the inner bottom portion 80. That is, the bag body of the third embodiment has the structure in which the position limiting component is provided with the inner bottom portion in the bag body of the first embodiment or the second embodiment. Therefore, in the description of the second embodiment, the detailed description of the other structures except the inner bottom portion of the position limiting component is omitted.

[0326] (inner bottom)

[0327] like Fig.13 As shown, the position limiting member has an inner bottom 80 . Fig.13 The example of shows an example in which the bag body of the third embodiment is a bag body of the second embodiment in which the position restriction member has a bottom. The inner bottom may also be called a small bottom because it is a part smaller than the bottom.

[0328] The inner bottom portion may be independent of the limiting wall portion, but is preferably formed in a manner that the inner bottom portion is continuously connected to the limiting wall portion. The same applies to the continuity of the inner bottom portion and the sandwiched wall. Fig.13 In the example of , the inner bottom 80 is formed to be continuous with the sandwiched wall 50 at the position of the lower end of the sandwiched wall 50 and to be continuous with the limiting wall 31 at the position of the lower end of the limiting wall 31. The inner bottom 80 supports the content (e.g., the container 200) from below in the interior of the space 23 (inside the small space 33). In the case where the content is a container (a container containing liquid such as a beverage as the container content), "supporting the content from below" means that, for example, Fig.14 A. Fig.14As 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 arranged in the small space portion 33, the inner bottom 80 is arranged on the lower surface side of the container 200, which includes any one of a case where the contents are supported from the lower surface side by only the inner bottom 80 and a case where the contents are supported from the lower surface side by the inner bottom 80 and the bottom 22.

[0329] (Inclined surface)

[0330] 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 portion 80 is preferably as follows: Fig.15 B. Fig.15 As shown in C, there is a direction ( Fig.15 B. Fig.15 The inclined surface 81 is formed on the upper surface side of the inner bottom portion, and is inclined downward in the direction of approaching the sandwiched wall 50. The inclined surface formed on the upper surface side of the inner bottom portion can be formed in the entire range from the boundary position between the inner bottom portion and the limiting wall portion to the boundary position TB between the inner bottom portion and the sandwiched wall, or can be formed in the area from the boundary position between the inner bottom portion and the limiting wall portion to the specified position of the inner bottom portion. From the viewpoint of firmly supporting the contents of the container from below by the inner bottom portion and obtaining the effect based on the inclined surface 81, it is preferred that the inclined surface is formed in the area from the boundary position between the inner bottom portion and the limiting wall portion to the specified position of the inner bottom portion.

[0331] When the limiting wall portion of the position limiting member is in the first shape state ST1, and the inclined surface as described above is formed on the upper surface side of the inner bottom, when a container as a content is arranged in the small space portion, Fig.16 As shown, the container 200 is slightly inclined toward the peripheral wall portion 21 of the main body, and the upper end side of the container is easily pressed toward the inner surface side of the peripheral wall portion (the side in the direction of arrow FE), and a gap 35 is easily formed between the outer peripheral surface of the container body and the upper end side of the limiting wall portion. If a gap is formed between the outer peripheral surface of the container body and the upper end side of the limiting wall portion, even if the container contents (such as liquids such as beverages) leak out of the container body, the container contents are likely to fall into the gap between the limiting wall portion and the container body, and it is difficult for the container contents to splash and drip outside over the limiting wall portion.

[0332] (Waterproof)

[0333] In addition, when liquid (liquid such as a beverage in the container) splashes and drips into the gap between the limiting wall and the container body, the inner bottom is preferably waterproof from the viewpoint of preventing the splashed liquid from reaching the inner bottom and damaging the inner bottom, thereby reducing the support function of the container from below. From the viewpoint of preventing damage to the position limiting component caused by the infiltration of liquid into the position limiting component, the entire position limiting component is preferably waterproof.

[0334] (lining)

[0335] Also like Fig.14 A. Fig.15 As shown in A of FIG. 1 , the inner bottom preferably has a lining 82 (bottom lining). In this case, the inner bottom 80 has a lining portion 83, and the state of the limiting wall portion 31 of the position limiting member can be smoothly changed from the first shape state ST1 to the second shape state ST2, and the state of the limiting wall portion 31 can be changed from the second shape state ST2 to the first shape state ST1. In addition, as described above, when the inclined surface 81 is formed on the upper surface of the inner bottom, as shown in FIG. Fig.15 As shown in A, when the limiting wall is in the second shape state, it is preferred that the position of the lower end of the limiting wall is located above the position of the lower end of the sandwiched wall. In this case, if the state of the limiting wall is changed from the second shape state to the first shape state, the position of the lower end of the limiting wall is located above the position of the lower end of the sandwiched wall, thereby more reliably forming the inclined surface 81 on the upper surface of the inner bottom 80.

[0336] [3-2 Functions and Effects]

[0337] According to the bag body of the third embodiment, the same effects as those of the first embodiment can be obtained. In addition, when the bag body of the third embodiment has the same structure as that of the second embodiment, the same effects as those of the second embodiment can be obtained.

[0338] According to the bag body of the third embodiment, the inner bottom portion 80 is provided. Therefore, even when the beverage leaks out of the container, it is possible to significantly reduce the possibility that the bag body is wetted by the liquid.

[0339] [3-3 Modification Example]

[0340] (Variant 1)

[0341] According to the bag body of the third embodiment, Fig.17 A. Fig.17 As shown in B, the position limiting component can also omit the sandwiched wall (variant 1). Fig.17 A. Fig.17In the example of B, the outer edge 84 of the inner bottom 80 (the edge facing outward among the edge portions of the inner bottom 80) is joined to the peripheral wall. In this case, when the limiting wall is in the second shape state, as shown in FIG. Fig.17 As shown in B, the lower end of the limiting wall portion is preferably located above the lower end of the outer edge portion 84 of the inner bottom portion 80 .

[0342] (Variant 2)

[0343] In the bag body of the third embodiment, an absorber for absorbing the liquid transferred and flowing down from the outer peripheral surface of the container may be provided on the upper surface of the inner bottom 80. Examples of the absorber include facial tissue, SAP, and the like.

[0344] (Variant 3)

[0345] The bag body according to the third embodiment may also be provided with the configurations shown in the modification of the first embodiment and the modification of the second embodiment.

[0346] [4. Implementation Method 4]

[0347] [4-1 Composition]

[0348] The bag body according to the fourth embodiment has a configuration in which a restriction wall reinforcement structure is provided on the position restriction member in any of the bag bodies according to the first to third embodiments.

[0349] (Reinforcement structure of the restraining wall)

[0350] like Fig.18 , Fig.19 As shown, the limiting wall reinforcement structure is a folded portion or a reinforcement member. Fig.18 A. Fig.18 B. Fig.18 C represents an example in which the restriction wall reinforcement structure is the folded portion 100 . Fig.19 A. Fig.19 B shows an example in which the restriction wall reinforcement structure is the reinforcement member 101 .

[0351] (Fold back)

[0352] In the case where the limiting wall reinforcement structure is the folded portion 100, in the position limiting component, as Fig.18 As shown in FIG. 8A , a folded portion 100 is formed at the upper end 36 of the limiting wall portion 31 . Fig.18 In the folded portion 100 shown in A of FIG. 1 , a predetermined portion of the upper end 36 side of the limiting wall portion 31 is folded back toward the opposite surface 34 side. However, this is an example, and the folded portion may also be Fig.18As shown in C, a predetermined portion of the upper end side of the limiting wall portion is folded back toward the opposite side of the opposite surface 34. The facing portions between the folded back portion and the non-folded back portion of the limiting wall portion can be bonded to each other by an adhesive. Fig.18 As shown in FIG. 1B , when the lower end of the limiting wall portion is located above the lower end of the sandwiched wall, it is preferred that a folded 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 located above the lower end of the sandwiched wall, it is easy to form an inclined surface 81 on the upper surface of the inner bottom 80, and the folded portion 100 is formed at the upper end 36 of the limiting wall portion 31, thereby further stabilizing the shape of the upper end 36 of the limiting wall portion 31, stabilizing the shape of the gap 35, and further improving the effect of the inclined surface 81.

[0353] (Reinforcement parts)

[0354] In the case where the limiting wall reinforcement structure is the reinforcement member 101, in the position limiting member, as Fig.19 A. Fig.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 arranged relative to any one of the opposite surface 34 side or the surface side opposite to the opposite surface 34. The reinforcing member 101 can also be arranged respectively relative to both the opposite surface 34 side and the surface side opposite to the opposite surface 34. In addition, the material of the reinforcing member 101 is not particularly limited. As the material of the reinforcing member, paper materials, resins (resin sheets), metals, etc. can be cited, but from the viewpoint of reducing the environmental burden and the ease of disposal after use, it is preferably composed of paper materials. As the material of the reinforcing member, it is preferable to use a material with stronger toughness than the position limiting member.

[0355] (Combination of reinforcement member and folded back portion)

[0356] As the limiting wall reinforcement structure, it can also be, for example Fig. 20 A. Fig. 20 B. Fig. 20 As shown in C, a reinforcing member 101 and a folded portion 100 are used. For example, in Fig. 20 A. Fig. 20 In the example of B, a reinforcing member 101 is provided at the upper end of the limiting wall portion, and the upper end of the limiting wall portion 31 has a folded portion 100, and the folded portion 100 is formed in a manner covering the reinforcing member 101 (in a manner wrapping the reinforcing member 101).

[0357] In addition, it is not limited to the case where the reinforcing member is wrapped by the folded back portion, and it may also be such that Fig. 20 As shown in FIG. 3C , a reinforcing member 101 is attached to the outside of the folded portion 100 .

[0358] [4-2 Functions and Effects]

[0359] According to the bag body of the fourth embodiment, the same effect as any one 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 restriction member becomes more resilient, thereby making it difficult for the shape of the bag body to collapse when the container is arranged in a small space.

[0360] [4-3 Modification Example]

[0361] (Variant 1)

[0362] In the bag body of the fourth embodiment, the reinforcing member may be arranged on the surface of the restricting wall portion such that the up-down direction is the longitudinal direction of the reinforcing member (modification 1).

[0363] (Variant 2)

[0364] The bag body according to the fourth embodiment may be provided with the configurations shown in the modification of the first embodiment, the modification of the second embodiment, and the modification of the third embodiment.

[0365] [5. Implementation Method 5]

[0366] [5-1 Composition]

Fig.21 In the example of B, it is formed into a trapezoidal shape. Fig. 22 A. Fig. 22 B. Fig. 22 As shown in C, the upper end of the second wall portion is covered by the cover portion 120, thereby forming a state in which the opening portion is firmly sealed. From the perspective of forming this state, the cover portion is preferably formed over the entire width of the first wall portion. Fig. 22 A. Fig. 22 B. Fig. 22 C is a diagram for explaining a state where the opening 24 is covered by the cover 120 .

[0372] (Adhesive placement section)

[0373] Preferably, the cover 120 is provided with an adhesive placement portion 121 where an adhesive is placed, and the adhesive can be bonded to the second wall surface when the cover covers the upper end of the second wall surface. The adhesive placement portion 121 can be a sealing member or the like. As the sealing member, a double-sided tape can be exemplified.

[0374] (Release Paper)

[0375] When the bag is not in use, from the viewpoint of preventing garbage from being attached to the adhesive placement part and preventing the adhesive placement part from coming into contact with other unintended items, it is preferred that a release paper 122 be installed so as to cover the surface of the adhesive placement part. The release paper is configured so that it can be released from the state of being attached to the surface of the adhesive placement part when the bag is not in use (the release paper can be peeled off) when the bag is in use. As the release paper, a sealing material formed of a material having weak adhesion to the adhesive constituting the adhesive attachment part can be used.

[0376] In addition, the release paper can be completely separated from the bag body, but is preferably constructed as follows. Fig. 22 A to Fig. 22 As shown in C, even after the release paper is peeled off from the adhesive attachment portion so that the release paper does not separate, a part of the release paper is maintained in a state of being adhered to the bag body 10. In this case, the possibility of the release paper 122 separating from the bag body and becoming independent waste can be suppressed.

[0377] [5-2 Functions and Effects]

[0378] According to the bag body of the fifth embodiment, the same effects as those of any of the bags 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 retaining property of the space 23 .

From the viewpoint of being able to stabilize the curved structure 170 and forming the grippable gap 171, the shape of the adhesive member 160 is preferably a shape that enables the second adhesive surface forming portion 162 to be located near both ends of the curved structure 170 separated in the long side direction of the curved structure 170, and enables the first adhesive surface forming portion 161 to be located at a position separated from the curved structure 170.

[0413] (Bending structure)

[0414] The bending structure 170 is defined by a portion formed by bending the first wall surface 25A and the second wall surface 25B in such a manner that the outer surface of the first wall surface 25A and the outer surface of the second wall surface 25B face each other while a specified portion (the first upper end side wall surface portion 165A) on the upper end side of the first wall surface 25A overlaps with a specified portion (the second upper end side wall surface portion 165B) on the upper end side of the second wall surface 25B. The state where the first upper wall portion 165A and the second upper wall portion 165B overlap includes not only a state where the inner surface of the first upper wall portion 165A and the inner surface of the second upper wall portion 165B are in contact, but also a state where the distance Wh between the first upper wall portion 165A and the second upper wall portion 165B is narrowed so as to be smaller than the sum of the thicknesses of the first upper wall portion 165A and the second upper wall portion 165B. The state where the first upper wall portion 165A and the second upper wall portion 165B overlap is preferably a state where the inner surface of the first upper wall portion 165A and the inner surface of the second upper wall portion 165B are in contact.

[0415] In addition, a predetermined portion of the upper end side of the peripheral wall portion 21 that is to form the curved structure 170 is referred to as a first peripheral wall portion forming portion 166, and a portion other than the first peripheral wall portion forming portion 166 is referred to as a second peripheral wall portion forming portion 167. That is, in the case where the curved structure 170 is assumed to be formed in the bag body 10, the portion that forms the curved structure 170 is referred to as the first peripheral wall portion forming portion 166, and a 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 a portion of the peripheral wall portion 21 defined by a range from a portion formed by the opening portion 24 that will become an end portion of the peripheral wall portion 21 to a portion of the curved peripheral wall portion 21 that is close to the bottom 22.

[0416] Fig. 27 A to Fig. 27 In the example of the bag body 10 shown in C, the curved structure 170 is preferably as follows Fig.28 , Fig.29 That is, Fig.28 A. Fig.28 As shown in B, a predetermined portion of the first peripheral wall forming portion 166 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). Fig.28 In the example of A, the second adhesive surface forming portion 162 protrudes upward from the first bent end 172 .

[0417] The bag body 10 is formed by further bending the first peripheral wall forming portion 166 at the lower end of the first peripheral wall forming portion 166 in a direction toward the second wall surface portion 25B from the state where the first bending end 172 is set as the upper end. In other words, the first peripheral wall forming portion 166 is bent multiple times ( Fig.28 , Fig.29 In this case, the bend is twice. Fig.29 As shown, a curved structure 170 is formed. Therefore, Fig.29 A. Fig.29 In the example of B, the curved structure 170 is defined by a portion in which the first wall surface 25A and the second wall surface 25B are bent toward the second wall surface 25B in such a manner that the outer surface of the first wall surface 25A and the outer surface of the second wall surface 25B face each other. Fig.29 A. Fig.29 In the example of B, the bent structure 170 is a bent structure portion formed by multiple bending. The bent structure 170 is the above-mentioned bent structure portion, and thus, in the bent structure 170, the opening 24 is concealed.

[0418] In addition, when the curved structure 170 is formed, Fig.29 A. Fig.29 As shown in FIG. 1B, at least a portion of the second bonding surface forming portion 162 is in a state of facing the outer surface of the second wall surface portion 25B without passing through the first wall surface portion 25A. That is, when the curved structure 170 is formed, the position of the adhesive member 160 is determined so that at least a portion of the second bonding surface forming portion 162 can be bonded to the outer surface of the second wall surface portion 25B. Furthermore, when the curved structure 170 is not formed, as shown in FIG. Fig. 27 A to Fig. 27 As shown in C, the second bonding surface forming portion 162 avoids bonding with respect to the outer surface 21B of the peripheral wall portion 21 .

[0419] When the curved structure 170 is formed, Fig.30 A. Fig.30As shown in B, it is preferred that the second adhesive surface forming portion 162 is bonded to at least the outer surface of the second wall surface 25B. In this way, the second adhesive surface forming portion 162 is bonded to the outer surface of the second wall surface 25B, thereby making it easy to fix the curved structure 170. The curved structure 170 becomes a structural portion that conceals the opening 24 as described above, and the second adhesive surface forming portion 162 is bonded to at least the second wall surface 25B, thereby preventing a third party other than the user from opening the opening 24 of the bag body and improperly inserting a hand into the bag body 10 from the opening 24. Moreover, the second adhesive surface forming portion 162 is bonded to at least the outer surface of the second wall surface 25B, thereby stabilizing the curved structure 170. Therefore, the structure of the "gripable gap 171" described later formed along with the formation of the curved structure 170 can be stabilized.

[0420] (gap)

[0421] When the second adhesive surface forming portion 162 is bonded to the peripheral wall portion 21, it is preferably configured so that a grippable gap 171 can be formed between the first peripheral wall portion forming portion 166 forming the curved structure 170 in the peripheral wall portion 21 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 the hand into the gap 171 and carry the bag with the 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 from the gap 171.

[0422] (Peel off parts)

[0423] The bag body 10 of the seventh embodiment is preferably as follows Figures 27 to 30 As shown, a peeling member 175 having peelability is installed in a manner covering the second adhesive surface forming portion 162. As the peeling member 175, so-called peeling paper can be preferably used. The peeling member 175 is preferably configured in a manner covering the second adhesive surface forming portion 162 in a state where the curved structure 170 is not formed. And, the peeling member 175 is peeled off from the second adhesive surface forming portion 162 in a state where the curved structure 170 is formed, so that the second adhesive surface forming portion 162 is exposed.

[0424] In addition, the peeling member 175 may be configured to avoid being completely separated from the adhesive member 160 . Fig.30 In example A, the peeling member 175 is joined at the end of the adhesive member 160 (the end located further on the front end side from the forming portion of the second adhesive surface forming portion 162), and 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 of being connected at the end of the adhesive member 160.

[0425] also, Fig.30 A. Fig.30 B does not prohibit the peeling member 175 from being completely separated from the adhesive member 160 .

[0426] [7-2 Functions and Effects]

[0427] According to the bag body 10 of the seventh embodiment, the adhesive member 160 and the curved structure 170 having the above-mentioned configuration are formed, thereby forming a grippable gap 171, thereby allowing the user to insert a hand into the gap 171 to carry the bag body 10. In addition, by forming the adhesive member 160 and the curved structure 170, the curved structure 170 can be stabilized, and the state of hiding the opening 24 can be stably formed, thereby suppressing the risk of a third party improperly inserting a hand into the space 23 from the opening 24.

[0428] [7-3 Modification Example]

[0429] (Variant 1)

[0430] Regarding the bag body 10 of the seventh embodiment, Fig.29 In the example of the embodiment, the second adhesive surface forming portion 162 is configured to be bonded to the second wall surface portion 25B when the curved structure 170 is formed, but this is an example. The bag body 10 of the seventh embodiment may also be configured to be bonded to the first wall surface portion 25A and the second wall surface portion 25B when the curved structure 170 is formed (variant 1). In this case, when the curved structure 170 is formed, it is preferred that the second adhesive surface forming portion 162 is arranged across the lower end 173 of the curved structure 170 and is bonded to the outer surface of the first wall surface portion 25A and the outer surface of the second wall surface portion 25B. The curved structure 170 is a structural part that conceals the opening 24 as described above, and the second adhesive surface forming part 162 is bonded to at least the outer surface of the first wall surface 25A and the outer surface of the second wall surface 25B, thereby more effectively preventing a third person other than the user from illegally opening the opening 24 of the bag body 10. That is, the second adhesive surface forming part 162 is arranged across the lower end 173 of the curved structure 170 and is bonded to the first wall surface 25A and the second wall surface 25B, thereby, when a third person other than the user illegally opens the opening 24 of the bag body 10, it is easy to leave an illegal trace due to the occurrence of a break in the adhesive member 160, thereby more effectively preventing a hand from being illegally inserted into the bag body 10 from the opening 24.

[0431] (Variant 2)

[0432] In the bag body 10 of the seventh embodiment, the curved structure 170 may be as follows: Fig.36 A. Fig.36 As shown in B, it is defined by a portion formed by bending the first wall surface 25A and the second wall surface 25B toward the first wall surface 25A side in a state where the outer surface of the first wall surface 25A and the outer surface of the second wall surface 25B face each other.

[0433] [7-3 Reference Example]

Fig.32 As shown, in the main body 20 , an adhesive placement portion 179 for sealing the opening may be provided on the inner surface 21A of the peripheral wall portion 21 . Fig.32 In the example of FIG. 1 , the adhesive placement portion 179 for closing the opening is placed on the upper end side of the peripheral wall portion 21 and on the inner surface side of the peripheral wall portion 21. The adhesive placement portion can be, for example, a double-sided tape or the like.

[0435] [8 8th Implementation Method]

[0436] [8-1 Composition]

[0437] The bag body 10 of the eighth embodiment includes the sealing sheet 180 described below in any of the bag bodies 10 of the first to seventh embodiments.

[0438] 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, and the peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of wall portions facing each other. The main body 20 forms a space portion 23 surrounded by the bottom 22 and the peripheral wall portion 21 and capable of storing the 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 shown in FIG. Fig.33 A to Fig.33 As shown in FIG. 1B , a sealing sheet 180 is attached to the outer surface 21B of the peripheral wall portion 21. In addition, the structure of the main body 20 (the peripheral wall portion 21 and the bottom portion 22, etc.) is the same as that described in the first to seventh embodiments, so detailed description is omitted. Figure 33 to Figure 35 as well as Fig.37 For the sake of convenience, the description of the position limiting component 30 is omitted.

[0439] (Sealing sheet)

[0440] The sealing sheet 180 has a sealing member 181 which can be detachably mounted. Fig.33 A. Fig.33 In the example of B, there is a structure in which the sealing component 181 is detachably attached to the sealing base 182. The sealing component 181 has an adhesive surface forming portion 183, and is detachably attached to the surface of the sealing base 182 in a state in which the adhesive surface forming portion 183 faces the sealing base 182. In addition, detachably attached means that it can be peeled off and re-adhered relative to the surface of the sealing base 182 (the case of "re-adhering" also includes the case where the adhesive force of the sealing component 181 to the sealing base 182 is reduced when re-adhering). The sealing sheet 180 is attached to a specified 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 avoiding the portion of the peripheral wall portion 21 where the curved structure 170 is formed. In addition, Fig.33 A. Fig.33 In the example of B, the sealing sheet 180 is attached to the second wall surface 25B in the peripheral wall portion 21, but this is an example. At least a part of the sealing sheet 180 may be attached to a portion separated from the second wall surface 25B.

[0441] (Sealing parts)

[0442] In the bag body 10 of the seventh embodiment, when the curved structure 170 described later is formed, the sealing member 181 is arranged so as to straddle the lower end 173 of the curved structure 170 (condition 1). The sealing member is configured so as to be bonded to the peripheral wall portion 21 in a state where the bonding surface forming portion 183 faces the first wall surface portion 25A and the second wall surface portion 25B when the curved structure 170 is formed (condition 2).

[0443] The shape and number of the sealing members 181 included in the sealing sheet 180 are not particularly limited as long as they are configured to satisfy the above-mentioned conditions 1 and 2. Fig.33 A. Fig.33 In the example of B, the sealing member 181 is composed of two rectangular sealing materials having a predetermined size.

[0444] (Sealed Base)

[0445] The sealing base 182 can preferably use a component having a peelable surface as one surface. With the peelable surface as the surface (with the peelable surface relative to the sealing component 181 facing the front side), the back side of the sealing base 182 is attached to the peripheral wall portion 21, thereby being arranged on the outer surface 21B of the peripheral wall portion 21.

[0446] (Bending structure)

[0447] Regarding the bag body of the eighth embodiment, the curved structure 170 is defined by the same definition as the curved structure described in the seventh embodiment. That is, the curved structure 170 is defined by the portion formed by bending the first wall surface 25A and the second wall surface 25B in such a manner that the outer surface of the first wall surface 25A and the outer surface of the second wall surface 25B face each other in a state where a predetermined portion (first upper end side wall surface portion 165A) on the upper end side of the first wall surface 25A overlaps with a predetermined portion (second upper end side wall surface portion 165B) on the upper end side of the second wall surface 25B.

[0448] The first upper end side wall surface portion 165A and the second upper end side wall surface portion 165B are also defined by the same definition as the curved structure described in the seventh embodiment. Here, similarly to the content described in the seventh embodiment, the predetermined portion of the upper end side of the peripheral wall portion 21 that is scheduled to form the curved structure 170 in the peripheral wall portion 21 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, in the case where the curved structure 170 is assumed to be formed in the bag body 10, the portion that forms 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 a portion of the peripheral wall 21 defined by a range from a portion formed by the opening 24 to be the end of the peripheral wall 21 to a portion of the curved peripheral wall 21 close to the bottom 22 .

[0449] Fig.33 In the example of the bag body 10 shown in A, the curved structure 170 is preferably as follows Fig.33 B. Fig.37 A. Fig.37 In other words, Fig.33 B. Fig.37 A. Fig.37 As shown in FIG. 1B, in a state where the first upper end side wall surface portion 165A and the second upper end side wall surface portion 165B overlap, the first peripheral wall portion forming portion 166 is folded back toward the second wall surface portion 25B several times. Fig.33 B. Fig.37 A. Fig.37 As shown in B, a curved structure 170 is formed. Fig.33 B. Fig.37 A. Fig.37In the example of B, the curved structure 170 is defined by a portion formed by bending the first wall portion 25A and the second wall portion 25B toward 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 (a state where the outer surface of the first wall portion 25A overlaps the outer surface of the second wall portion 25B). Fig.33 B. Fig.37 A. Fig.37 In the example of B, the bent structure 170 is a bent structure portion formed by multiple bending. The bent structure 170 is the above-mentioned bent structure portion, and thus, in the bent structure 170, the opening 24 is concealed.

[0450] also, Fig.33 The curved structure 170 shown in B is an example. The curved structure 170 may be defined by a portion formed by bending the first wall surface 25A and the second wall surface 25B toward the first wall surface 25A side in a state where the outer surface of the first wall surface 25A and the outer surface of the second wall surface 25B face each other.

[0451] When the curved structure 170 is formed, Fig.33 B. Fig.37 As shown in A of FIG. 1 , the sealing member 181 is drawn out from the sealing sheet 180. Furthermore, the sealing member 181 is arranged on the outer surface 21B of the peripheral wall portion 21 in a manner that straddles the lower end 173 of the curved structure 170. At this time, the sealing member 181 is bonded to the peripheral wall portion 21 in a state where the bonding surface forming portion 183 faces the first wall portion 25A and the second wall portion 25B. The sealing member 181 is bonded to the first wall portion 25A and the second wall portion 25B in this manner, thereby fixing the curved structure 170.

[0452] In addition, the sealing member 181 is Fig.33 In the example shown in B, they are arranged near both end portions of the curved structure 170 along the long side direction, but this is only an example.

[0453] Regarding the bag body 10 of the eighth embodiment, when the sealing member 181 is bonded to the peripheral wall portion 21, Fig.37 As shown in FIG. 1B , a grippable gap 171 can be formed 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 other than the first peripheral wall forming portion 166 as described in the seventh embodiment. By forming such a gap 171, the user can insert the hand into the gap 171 and carry the bag body 10 by holding the hand.

[0454] [8-2 Functions and Effects]

[0455] According to the bag body 10 of the eighth embodiment, the sealing member 181 is provided, and thus, when the curved structure 170 is provided, the gap 171 that can be gripped can be stably formed as a structure, and thus, the user can insert the hand into the gap 171 and carry the bag body 10. In addition, the curved structure 170 is fixed by the sealing member 181, and thus, the curved structure 170 is stabilized, and the state of hiding the opening 24 can be stably formed, and thus, the risk of a third party improperly inserting the hand from the opening 24 into the space 23 can be suppressed.

[0456] [8-3 Modification Example]

[0457] (Variant 1)

[0458] In the eighth embodiment, it can also be as follows Fig.34 A. Fig.34 B. Fig.35 A. Fig.35 As shown in FIG. 1B , the sealing member 181 has a through hole 184 (modification 1). In this case, the through hole 184 is configured so that the gap 171 can be exposed from the through hole 184 when the sealing member 181 is bonded to the outer surface 21B of the peripheral wall portion 21 . Fig.34 A. Fig.34 B shows an example of a case where one through hole 184 is formed. Fig.35 A. Fig.35 In B, it is indicated that the through hole 184 forms a plurality of ( Fig.35 A. Fig.35 An example of a situation where there are three in B).

[0459] [8-4 Reference Example]

[0460] The bag body of the eighth embodiment may be a bag body in which the position restriction member is omitted from each of the bag bodies of the first to sixth embodiments (that is, Fig.31 As shown in FIG. 1 , the sealing sheet 180 (reference example) is provided in the bag body consisting only of the main body. Fig.32 As shown, an adhesive placement portion 179 for closing the opening may be provided. The adhesive placement portion 179 for closing the opening is placed on the upper end side of the peripheral wall portion 21 and on the inner surface 21A side of the peripheral wall portion 21. The adhesive placement portion 179 may be a double-sided tape or the like.

[0461] [9 9th Implementation Method]

[0462] The bag body 10 of the ninth embodiment includes the bag body 10 of any of the first to eighth embodiments and includes the bag body fragile portion 190 described below.

[0463] 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, and the peripheral wall portion 21 has a first wall portion 25A and a second wall portion 25B as a set of wall portions facing each other. The main body 20 forms a space portion 23 surrounded by the bottom 22 and the peripheral wall portion 21 and capable of storing the 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 shown in FIG. Fig.38 A to Fig.38 As shown in FIG. 1B , a bag body weakening portion 190 is formed on the peripheral wall portion 21. In addition, the structure of the main body 20 (the peripheral wall portion 21 and the bottom portion 22, etc.) is the same as that described in the first to eighth embodiments, so detailed description is omitted. Fig.38 ) In the figure, for the sake of convenience, the description of the position limiting component 30 is omitted. Fig.38 An example in which the bag body of the fifth embodiment has a bag body fragile portion 190 formed on the second wall surface portion 25B of the peripheral wall portion 21 of the main body.

[0464] (Bag fragile part)

[0465] 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 the bag body weakening portion include a perforated structural portion and a half-cut portion. In addition, from the viewpoint of maintaining the temperature inside the bag body 10 as much as possible, the bag body weakening portion is preferably a half-cut portion. The half-cut portion can be defined as a structural portion that cuts the peripheral wall portion 21 to a predetermined depth along the thickness direction of the peripheral wall portion 21, and the depth of "cutting into the peripheral wall portion 21" that forms the half-cut portion is not limited to the portion that cuts into the peripheral wall portion 21 to half the thickness of the peripheral wall portion 21. The depth of cutting into the peripheral wall portion 21 may exceed half the thickness of the peripheral wall portion 21, or may be less than half the thickness of the peripheral wall portion 21. The half-cut portion may be formed by cutting from the inner surface 21A of the peripheral wall portion 21 toward the outer surface 21B, or may 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 half-cut portion is preferably formed by cutting from the inner surface 21A toward the outer surface 21B of the peripheral wall portion 21 .

[0466] The bag body fragile portion 190 is Fig.38In the example, the bag body 10 is formed into a U-shape, but this is an example. The shape of the bag body fragile part 190 is not particularly limited. In addition, by breaking the bag body fragile part 190 to form the cover part 191, or by lifting the cover part 191 outward and breaking the bag body fragile part 190, the space part 23 of the bag body 10 can be exposed, and the contents stored in the space part 23 can be taken out. Fig.38 A. Fig.38 In the example of B, the cover surface 191 is lifted up in the outward direction from the bottom to the top, thereby causing the rupture of the bag fragile part 190 to develop, and the space part 23 of the bag body 10 can be exposed. However, this is an example of the cover surface 191. The cover surface 191 can also be formed so that the space part 23 of the bag body 10 is exposed by lifting the cover surface 191 in the outward direction from the top to the bottom (lifting it downward), and the cover surface 191 can also be formed so that the space part 23 of the bag body 10 is exposed by lifting the cover surface 191 in a door shape.

[0467] The bag body fragile portion 190 is Fig.38 In the example, the bag body fragile portion 190 is formed on the second wall portion 25B, but this is an example, and it may be formed on the first wall portion 25A, or may be formed on both the first wall portion 25A and the second wall portion 25B. In addition, the bag body fragile portion 190 may be formed on the entire surface of the peripheral wall portion 21. In addition, the bag body fragile portion 190 may be formed in a manner surrounding the entire outer circumference of the peripheral wall portion 21.

[0468] (Pull Tab)

[0469] From the viewpoint of making it easy to displace the cover surface 191, it is preferable to provide a pull tab 192 on the cover surface 191. The user pinches the pull tab 192 and pulls it outward, thereby displacing (lifting) the cover surface 191 and causing the rupture of the bag body fragile part 190 to develop. In addition, as the cover surface 191 is displaced, the rupture of the bag body fragile part 190 develops, forming a state in which the space part 23 of the bag body 10 is exposed, and the contents stored in the space part 23 can be taken out.

[0470] [10 10th embodiment]

[0471] [10-1 Composition]

[0472] In the bag body of the tenth embodiment, Fig.39 A. Fig.39 B. Fig.39As shown in C, similarly to the fifth embodiment, a cover portion 120 is provided in any one of the bags of the first to fourth embodiments, and an adhesive configuration portion 121 is provided on the cover portion 120, and a cover penetration portion and a main body penetration portion are respectively formed on the cover portion and the main body, so that a gripping structure portion that functions as a handle of the bag body can be formed when the opening of the main body is closed by the cover portion.

[0483] [10-3 Modification Example]

[0484] (Variant 1)

[0485] In the bag body of the tenth embodiment, the shapes of the cover penetration portion 193 and the main body penetration portion 195 are not limited to a rectangular shape, and may be other shapes (variant 1). In the bag body 10 of the variant 1 of the tenth embodiment, for example, the shapes of the cover penetration portion 193 and the main body penetration portion 195 may be as follows: Fig.41 The illustrated shape is an ellipse, but it may be a triangle, a polygon, or an indefinite shape. In addition, the shapes of the cover penetration portion 193 and the main body penetration portion 195 may be the same or different from each other.

[0486] (Variant 2)

[0487] In the bag body of the tenth embodiment, the cover penetration portion 193 can be as follows Figure 42 to Figure 47 In the modification 2, the cover penetration portion 193 is preferably formed in a shape similar to the grip structure reinforcement portion 196 .

[0488] (Grip structure reinforcement)

[0489] The gripping structure reinforcement portion 196 can be determined as a portion having the following structure, wherein a straight line connecting the two ends (positions HP1 and HP2) in the long side direction of the cover portion through-portion 193 is used as the base end BP (the base end BP of the gripping structure reinforcement portion 196), and the entire gripping structure reinforcement portion 196 can be rotated from the base end to the front end TP (the front end TP of the gripping structure reinforcement portion 196) with the base end BP as the rotation axis.

[0490] (First example of the cover penetration portion and the grip structure reinforcement portion)

[0491] Fig.42 , Fig.43 , Fig.46 The first example of the cover penetration portion 193 and the grip structure reinforcement portion 196 is described in B. In the first example, Fig.42 As shown, the cover penetration portion 193 is formed so that the grip structure reinforcement portion 196 has the base end BP located at the upper side and the front end TP located at the lower side when the front end of the cover 120 is directed upward.

[0492] When the upper end of the second wall surface is covered by the cover 120 to close the opening 24, Fig.43 A to Fig.43 As shown in C, the gripping structure reinforcement portion 196 is in a state where the base end BP is located at the lower side and the front end TP is located at the upper side. Fig.46As shown in B, in this case, the gripping structure reinforcement portion 196 is preferably bent toward the space portion 23 side. If the gripping structure reinforcement portion 196 is bent toward the space portion 23 side, it can pass through the main body penetration portion 195 of the second wall portion 25B and the main body penetration portion 195 of the first wall portion 25A, so that the front end TP of the gripping structure reinforcement portion 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 gripping structure reinforcement portion 196 back toward the outer surface side of the first wall portion 25A, the structure of the gripping structure portion 194 can be reinforced. In addition, in the gripping structure reinforcement portion 196, it is preferred 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 gripping structure reinforcement portion 196 is folded back toward the outer surface side of the first wall portion 25A. In this case, a predetermined portion of the front end TP side of the gripping structure reinforcement portion 196 can be bonded to the outer surface side of the first wall surface portion 25A, and the structure of the gripping structure portion 194 can be further reinforced. In addition, in this case, the exposure of the space portion 23 can be reduced by the gripping structure reinforcement portion 196, thereby suppressing the risk of a third party or the like improperly inserting a hand into the space portion 23.

[0493] (Second example of the cover penetration portion and the grip structure reinforcement portion)

[0494] Fig.44 , Fig.45 , Fig.46 A of FIG. 1 shows a second example of the cover penetration portion 193 and the grip structure reinforcement portion 196. In the second example, Fig.44 As shown, the cover penetration portion 193 is formed so that the grip structure reinforcement portion 196 is in a state where the base end BP is located at the bottom and the front end TP is located at the top when the front end of the cover 120 is directed upward.

[0495] In the second example, when the upper end of the second wall surface is covered by the cover 120 to close the opening 24, Fig.45 A to Fig.45 As shown in C, the gripping structure reinforcement portion 196 is in a state where the base end BP is located at the upper side and the front end TP is located at the lower side. Fig.46 As shown in B, in this case, the gripping structure reinforcement portion 196 is preferably bent toward the space portion 23. This is similar to the first example, by folding back a predetermined portion of the front end TP side of the gripping structure reinforcement portion 196 toward the outer surface side of the first wall surface 25A while the front end TP of the gripping structure reinforcement portion 196 passes through the main body penetration portion 195 of the second wall surface 25B and the main body penetration portion 195 of the first wall surface 25A, thereby reinforcing the structure of the gripping structure portion 194. In addition, unlike the first example, in the second example, the front end TP is bent toward the upper side.

[0496] (Third example of the cover penetration portion and the grip structure reinforcement portion)

[0497] Fig.47 A. Fig.47 The third example of the cover penetration portion 193 and the grip structure reinforcement portion 196 is described in B. In the third example, Fig.47 As shown in A, when the front end of the cover 120 is facing upward, the cover through portion 193 is formed in such a manner that a first holding structure reinforcement portion 196A is formed as a holding structure reinforcement portion 196 in which the base end BP is located on the upper side and the front end TP is located on the lower side, and a second holding structure reinforcement portion 196B is formed in which the base end BP is located on the upper side and the front end TP is located on the lower side. Fig.47 In A, the cover penetration portion 193 is formed by an H-shaped slit structure. Fig.47 As shown in B, a structure that reinforces the structure of the gripping structure 194 described in the above-mentioned first and second examples can be formed, thereby achieving the effects obtained therewith.
