Description

[Technical Field]

[0001] For example, the present invention relates to a hanging bag that can be hung in a state where it contains items in a store or the like. [Background technology]

[0002] A packaging bag that is a hanging bag is described in Patent Document 1. This packaging bag is made by overlapping a front sheet and a back sheet that use a film laminated with oriented polypropylene and unoriented polypropylene, and by tightly sealing the peripheries of the front sheet and the back sheet and providing a sealing line that crosses the bag body at a position a predetermined distance below the upper end, with the sealing line as the boundary, forming a bag portion below for storing products and a header above for providing a hanging hole. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3082838 Summary of the Invention [Problem to be solved by the invention]

[0004] However, because the packaging bag described in Patent Document 1 employs a film in which oriented polypropylene and unoriented polypropylene are laminated, if the packaging bag is disposed of by, for example, landfilling or dumping into the ocean, the packaging bag will not decompose for a long period of time and will remain in the ground or ocean. Therefore, the packaging bag described in Patent Document 1 may cause an environmental burden.

[0005] Therefore, the present invention provides a hanging bag that can contribute to reducing the environmental load. [Means for solving the problem]

[0006] The present invention provides a hanging bag comprising a bag-shaped bag body in which both ends in a first direction and one of one end and the other end in a second direction perpendicular to the first direction are closed, and the other of the one end and the other end is open, and a other sealing portion provided on the other end of the bag body and capable of sealing the open other end, wherein a hanging portion for hanging the bag body is formed on the one end or the other end of the bag body, and the bag body is made of a paper material.

[0007] According to the above configuration, for example, the item can be stored in the bag body through the other part that opens, and by sealing the other part with the other sealing part, the item can be prevented from coming out of the other part, and the bag body can be hung by the hanging part.In addition, since the bag body is made of paper material, for example, the bag body can be reused as a paper resource when discarded, which contributes to reducing the environmental burden.

[0008] Furthermore, in the hanging bag, the hanging portion may be configured as a through hole at the one portion that penetrates the bag body in a third direction perpendicular to the first direction and the second direction.

[0009] According to the above configuration, the hanging portion is configured as a through hole that penetrates the bag body in the third direction at one part of the bag body, so that, for example, when an item is placed inside the bag body through the opening at the other part, the item can be placed inside the bag body without getting caught on the hanging portion.

[0010] Further, in the hanging bag, the bag body has a front portion and a back portion arranged opposite each other in a third direction perpendicular to the first direction and the second direction, the front portion and the back portion include the other portion, the other portion of at least one of the front portion and the back portion has an extension portion formed therein extending from the other portion in the second direction, the extension portion being configured to be bendable toward the opening side of the other portion in the third direction, the other sealing portion including the extension portion and configured to seal the opening of the other portion when the extension portion is folded, and the hanging portion may be configured as a through hole penetrating the extension portion, the front portion, and the back portion in the third direction when the extension portion folded in the third direction overlaps the front portion and the back portion.

[0011] According to the above configuration, the hanging portion is configured as a through hole that penetrates the extension portion, the surface portion, and the back portion in the third direction, so that, for example, when the hanging bag is hung through the through hole by passing a hook provided on a display stand or the like, the hanging bag can be supported by the extension portion, the surface portion, and the back portion, so that the through hole is less likely to deform due to the weight and the bag can be hung securely.

[0012] In addition, in the hanging bag, the extension portion may be formed on the other portion of one of the front and back portions, and a hanging reinforcement portion that reinforces the hanging portion may be formed by joining one of the front and back portions and the folded extension portion in the third direction on the side of the other portion closer to the through hole than the through hole.

[0013] According to the above configuration, a hanging reinforcement portion that reinforces the hanging portion is formed by joining one of the front and back portions and the folded extension portion in the third direction on the side of the other portion closer to the through hole, so that, for example, when the hanging bag is hung through the through hole by a hook provided on a display stand or the like, the hanging reinforcement portion can prevent the strength of the through hole from decreasing.

[0014] Further, in the hanging bag, the bag body has a front portion and a back portion that are arranged opposite each other in a third direction perpendicular to the first direction and the second direction, the front portion and the back portion include the other portion, the other portions of the front portion and the back portion have extending portions formed thereon that extend in the second direction from the other portions, the extending portions formed on the other portions of the front portion and the back portion are connected on both sides in the first direction and are configured to be bendable to one side or the other side in the third direction so as to overlap the front portion and the back portion, the other sealing portion includes the extending portion and is configured to seal the other portion that opens when the extending portion is folded, and at least one of the extending portions formed on the other portions of the front portion and the back portion has a separation auxiliary portion formed thereon that allows the extending portions of the front portion and the back portion to be separated in the third direction.

[0015] According to the above configuration, the extension portion is bent so as to overlap the front surface portion and the back surface portion, thereby allowing the other sealing portion to seal the other surface portion, and when opening the other surface portion, the separation auxiliary portion separates the extension portions of the front surface portion and the back surface portion in a third direction, thereby allowing the other surface portion to be opened.

[0016] Further, in the hanging bag, the bag body has a surface portion and a back portion arranged opposite each other in a third direction perpendicular to the first direction and the second direction, the surface portion and the back portion include the one portion and the other portion, the hanging portion is configured as a through hole that penetrates the surface portion and the back portion in the third direction on one of the one portion and the other portion, and the surface portion and the back portion are configured to be joined in the third direction on the other side of the one portion and the other portion, closer to the through hole.

[0017] According to the above configuration, the surface portion and the back portion are joined in the third direction on the other side of the through hole, so that, for example, when an item is contained in the bag body and the item moves within the bag body, the item can be prevented from overlapping with the through hole.

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the hanging bag of the present invention will now be described. The hanging bag is intended to be hung and displayed in a storefront or the like, for example, with an article stored therein.

[0021] In the following description, the width direction of the hanging bag is referred to as the “first direction X,” the length direction of the hanging bag is referred to as the “second direction Y,” and the thickness direction of the hanging bag is referred to as the “third direction Z.” The first direction X and the second direction Y are perpendicular to each other, and the third direction Z is perpendicular to the first direction X and the second direction Y.

[0022] As shown in FIG. 1 , the hanging bag 1 of the first embodiment includes a bag body 2, a first sealed portion 240, and an second sealed portion 250. The bag body 2 is configured in a bag shape with a front portion 20 and a back portion 21 (described later) to accommodate an item. Here, "bag-shaped" refers to a bag formed by stacking two sheets, one on top of the other, and bonding the edges of the two sheets together to form a storage space for storing an item with the two sheets and an opening leading to the storage space, allowing an item to be placed into the storage space through the opening. The bag body 2 of this embodiment is configured in an envelope shape. Furthermore, the bag body 2 of this embodiment is configured such that one end 22, the other end 23 in the first direction X, and one end 24 in the second direction Y are closed, and the other end 25 in the second direction Y is open.

[0023] The bag body 2 is made of a paper material. Here, "paper material" refers to paper as defined in JIS P0001:1998. Examples of "paper" used in this embodiment include printing paper such as fine paper, coated paper, and lightly coated paper, and wrapping paper such as unbleached paper, semi-bleached paper, bleached paper, and semi-glossy paper. The thickness of the paper material, expressed as weight per unit area, ranges from 50 g / m² to 150 g / m². The bag body 2 of this embodiment is constructed by folding and adhering a paper member in the state shown in FIG. 2 along creases a and b. The bag body 2 of this embodiment also has a hanging portion A formed at one end 24 in the second direction Y. The hanging portion A will be described later. The cardboard forming the paper box is not included in the "paper" of this embodiment.

[0024] As shown in Fig. 1, the bag body 2 includes a front surface portion 20 and a back surface portion 21 that are arranged opposite each other in the third direction Z. The front surface portion 20 of this embodiment forms the surface of the bag body 2 in the third direction Z. As shown in Fig. 2, the front surface portion 20 includes a front main body portion 200 that is arranged on the front side in the third direction Z.

[0025] The front body portion 200 of this embodiment is configured as a rectangular sheet that is longer in the second direction Y than in the first direction X. The front body portion 200 has a front-penetrating portion A10 that penetrates in the third direction Z. The front-penetrating portion A10 of this embodiment is formed on one end (upper end in FIG. 2) of the front body portion 200 in the second direction Y. The front-penetrating portion A10 of this embodiment is formed as a circular hole. Note that the front-penetrating portion A10 of this embodiment is arranged in the center in the first direction X.

[0026] The back surface portion 21 constitutes the back surface of the bag body 2 in the third direction Z. The back surface portion 21 includes a first adhesive margin portion 210, a back main body portion 211, and a one-end extension portion 212 and an other-end extension portion 213 provided from the front main body portion 200 in the second direction Y. As shown in FIG. 2, the first adhesive margin portion 210 is provided continuing from the other end of the front main body portion 200 in the first direction X (the left end in FIG. 2). The first adhesive margin portion 210 overlaps with the front main body portion 200 by folding the first fold a, and is adhered to the back main body portion 211 (described later) in the third direction Z. The first adhesive margin portion 210 is configured to become shorter in the second direction Y as it moves away from the front main body portion 200 in the first direction X. Therefore, the first adhesive margin portion 210 can be overlapped with the front main body portion 200 without protruding in the second direction Y. Furthermore, in this embodiment, when one of the adhesive margins 210 is overlapped on the front main body portion 200, in order to prevent the front-penetrating portion A10 from being blocked, the length of the one of the adhesive margins 210 in the first direction X is shorter than the distance from the other end of the front main body portion 200 to the front-penetrating portion A10.

[0027] As shown in FIG. 2, the rear main body portion 211 is provided continuous from one end (the right end in FIG. 2) of the front main body portion 200 in the first direction X. By folding the first fold a, the rear main body portion 211 is overlapped and adhered to the one adhesive margin portion 210 that is overlapping the front main body portion 200. Therefore, the length of the rear main body portion 211 in the first direction X is set so that it overlaps the one adhesive margin portion 210. Furthermore, the rear main body portion 211 in the present embodiment is configured to be shorter than the front main body portion 200 in the first direction X and the second direction Y so as not to protrude from the front main body portion 200. On the other hand, the length of the rear main body portion 211 in the second direction Y is set so that it overlaps the one end extension portion 212 and the other end extension portion 213. A rear through-hole portion A12 that penetrates in the third direction Z is formed in the rear main body portion 211. The back-penetrating portion A12 is formed in the back main body portion 211 so as to communicate with the front-penetrating portion A10 when the back main body portion 211 is placed on top of the front main body portion 200. The back-penetrating portion A12 in this embodiment is a circular hole with a larger diameter than the front-penetrating portion A10.

[0028] As shown in FIG. 2, the one-end extending portion 212 is provided continuously from one end of the front main body portion 200 in the second direction Y (the upper end in FIG. 2). In this embodiment, the one-end extending portion 212 is configured to narrow in the first direction X as it moves away from the front main body portion 200 in the second direction Y. Therefore, the one-end extending portion 212 can be placed on the front main body portion 200 without protruding in the first direction X. In this embodiment, the one-end extending portion 212 is longer in the second direction Y than the other-end extending portion 213, which will be described later. In addition, the one-end extending portion 212 has a one-side through-portion A11 that penetrates in the third direction Z. This one-side through-portion A11 is formed so as to communicate with the back through-portion A12 when the second fold b is folded and the one-end extending portion 212 is placed on the back main body portion 211. In addition, the one-side through-portion A11 in this embodiment is configured as a circular hole with the same diameter as the front through-portion A10.

[0029] 2, the other-end extending portion 213 is provided continuous from the other end (the lower end in FIG. 2) of the front main body portion 200 in the second direction Y. The other-end extending portion 213 of this embodiment is configured so that its width in the first direction X narrows as it moves away from the front main body portion 200 in the second direction Y. This other-end extending portion 213 overlaps with the back main body portion 211 by folding the second fold b.

[0030] The one-side sealing portion 240 is the sealing portion on the closed side in the state before storing an item as shown in Figure 1. The one-side sealing portion 240 seals one end 24 of the bag main body 2 in the second direction Y. In this embodiment, the one-side sealing portion 240 seals one end 24 of the bag main body 2 in the second direction Y by overlapping and adhering the one-end extension portion 212 to the back main body portion 211. Therefore, in this embodiment, the one-end extension portion 212 is configured as the one-side sealing portion 240. Note that the relationship between "one side" and "other side" regarding the sealing portion is the same in the second and third embodiments.

[0031] As shown in FIG. 1 , the other-side sealing portion 250 is a sealing portion configured to be able to seal the other end 25 of the bag main body 2 in the second direction Y, which opens, before an article is stored. Here, in this embodiment, when an article (for example, a writing implement such as a mechanical pencil or a refill for a ballpoint pen) is stored in the bag main body 2 from the other end 25 side in the second direction Y, the second fold b is folded and the other-end extension portion 213 is overlapped and adhered to the rear main body portion 211, thereby sealing the other end 25 of the bag main body 2 in the second direction Y. Therefore, in this embodiment, the other-end extension portion 213 is configured as the other-side sealing portion 250. Note that, to make it easier to remove an article from the bag main body 2, the other-end extension portion 213 may be peelably adhered to the rear main body portion 211.

[0032] 1, the hanging portion A is for hanging the bag body 2. The hanging portion A of this embodiment is configured by communication between the front through-hole A10, the one-side through-hole A11, and the back through-hole A12. Therefore, the hanging portion A of this embodiment is configured as a through hole A1 that penetrates one end 24 of the bag body 2 in the second direction Y in the third direction Z.

[0033] In the bag body 2 of this embodiment, when the first fold a is folded from the state of the developed view shown in Fig. 2, the one glue tab 210 overlaps the front main body portion 200, and the back main body portion 211 overlaps and is adhered to the one glue tab 210, thereby closing the one end 22 and the other end 23 in the first direction X. Here, in this embodiment, the one glue tab 210 is configured to become shorter in the second direction Y as it moves away from the front main body portion 200 in the first direction X, and the back main body portion 211 is configured to be shorter than the front main body portion in the second direction Y. Therefore, as shown in Fig. 1, when the one glue tab 210 and the back main body portion 211 overlap, a recess 2a that is recessed on one end side in the second direction Y is formed at the other end in the second direction Y of the bag body 2 (the lower end in Fig. 1). Furthermore, by arranging the front body portion 200 and the rear body portion 211 opposite each other in the third direction Z, one end 24 and the other end 25 in the second direction Y are open, and the front through-hole A10 and the rear through-hole A12 are connected to each other.

[0034] Then, by folding the second fold b, the one-end extending portion 212 is overlapped and adhered to the back main body portion 211 so that the one-side through-portion A11 communicates with the back through-portion A12 and the front through-portion A10. As a result, in this embodiment, the one-side sealing portion 240 seals the one end 24 in the second direction Y, and the bag main body 2 shown in Figure 1 is formed in which the one end 22, the other end 23 in the first direction X, and the one end 24 in the second direction Y are closed. Furthermore, the one-side through-portion A11, the back through-portion A12, and the front through-portion A10 are communicated with each other, forming a through hole A1 that penetrates the bag main body 2 in the third direction Z.

[0035] Thereafter, an article is placed into the bag main body 2 from the other end 25 side in the second direction Y, and then the second fold b is folded, so that the other end extension portion 213 overlaps and is adhered to the back main body portion 211. As a result, in this embodiment, the other sealing portion 250 seals the other end 25 of the bag main body 2 in the second direction Y. In addition, the front surface portion 20 and the back surface portion 21 overlap in the third direction Z.

[0036] As described above, according to this embodiment, in the state shown in Fig. 1, an article can be placed into the bag body 2 from the other end 25 in the second direction Y where the bag body 2 is open. Here, in this embodiment, the hanging portion A is formed at one end 24 in the second direction Y of the bag body 2, so when an article is placed into the bag body 2, it can be placed smoothly without getting caught on the hanging portion A. Therefore, for example, workability can be improved when placing an article into the bag body 2 by machine.

[0037] Furthermore, in this embodiment, by overlapping and adhering the other end extension portion 213 to the back main body portion 211, the other sealing portion 250 can seal the other end portion 25 of the bag main body 2 in the second direction Y. This makes it possible to prevent articles from coming out of the bag main body 2.

[0038] In this embodiment, the bag body 2 can be hung and displayed by inserting a hook formed on a display stand, for example, into the hanging portion A configured as the through-hole A1.

[0039] Furthermore, in the first embodiment, the front main body portion 200, the rear main body portion 211, and the one-end extending portion 212 are overlapped, and the front through-hole A10, the rear through-hole A12, and the one-end through-hole A11 are connected to form the through-hole A1. Therefore, for example, when hanging the hanging bag 1 by passing a hook provided on a display stand or the like through the through-hole A1, the hanging bag 1 can be supported by the front main body portion 200, the rear main body portion 211, and the one-end extending portion 212, so that the through-hole A1 is less likely to deform due to the weight of the hanging bag 1, and the hanging bag can be hung securely.

[0040] Furthermore, the hanging bag 1 of this embodiment is configured by passing a through hole A1 as the hanging portion A through the bag body 2 in the third direction Z, and therefore can be easily manufactured, and can be manufactured more simply than, for example, a configuration in which a separate hook is attached to the bag body 2.

[0041] In addition, in this embodiment, the bag body 2 is made by folding and gluing a single piece of paper material as shown in Figure 2, so when it is discarded it can be reused as a paper resource, thereby contributing to reducing the environmental burden.

[0042] Furthermore, the hanging bag 1 of this embodiment has the bag body 2 formed by overlapping the front surface portion 20 and the back surface portion 21, which prevents the bag from becoming bulky in the thickness direction, that is, the third direction Z. In particular, the hanging bag 1 of this embodiment is formed by overlapping paper material having a thickness of 50 g / m2 to 150 g / m2, so unlike a paper box, the effort required for assembly to make it capable of containing items is relatively small, and there is no need to ensure space in the thickness direction, so that, for example, when storing or transporting in a warehouse, a larger number of hanging bags 1 can be stored compared to a paper box.

[0043] Furthermore, in the hanging bag 1 of this embodiment, the length in the first direction X of the one glue tab portion 210 is shorter than the distance from the other end in the first direction X of the front main body portion 200 to the front-penetrating portion A10. Therefore, when the one glue tab portion 210 is overlapped on the front main body portion 200, the front-penetrating portion A10 can be prevented from being blocked by the one glue tab portion 210, and when the back main body portion 211 is overlapped on the one glue tab portion 210, the front-penetrating portion A10 and the back-penetrating portion A12 can be communicated with each other.

[0044] Furthermore, according to the hanging bag 1 of the first embodiment, the back through-hole A12 is configured as a hole with a larger diameter than the front through-hole A10. That is, in the hanging bag 1 of the first embodiment, when the front main body portion 200, the back main body portion 211, and the one glue margin portion 210 are overlapped, the through-hole (back through-hole A12) of the member arranged in the middle in the third direction Z has a larger diameter than the other through-holes (front through-hole A10, one-side through-hole A11). Therefore, even if there is some misalignment in the overlapping state when the front main body portion 200, the back main body portion 211, and the one glue margin portion 210 are overlapped, the front through-hole A10, the back through-hole A12, and the one-side through-hole A11 can communicate with each other. Therefore, for example, when the front through-hole A10, the back through-hole A12, and the one-side through-hole A11 are formed by machine, processing errors can be prevented.

[0045] Furthermore, in the hanging bag 1 of the first embodiment, the back main body portion 211, which is located between the front main body portion 200 and the one end extension portion 212 stacked in the third direction Z, has a back penetration portion A12 with a larger diameter than the front penetration portion A10 and the one end penetration portion A11, so that the appearance is less likely to be unnatural.

[0046] Furthermore, in the hanging bag 1 of this embodiment, the front surface portion 20 and the back surface portion 21 (back main body portion 211, one glue tab portion 210, one seal portion 240, other seal portion 250) overlap in the third direction Z, ensuring strength in the third direction Z. Furthermore, as shown in FIG. 1 , the back main body portion 211 and one glue tab portion 210 overlap and are bonded in the third direction Z to form the back surface portion 21. This gives the back surface portion 21 stiffness, allowing the hanging bag 1 to maintain its shape, and eliminating the need to insert a shape-retaining backing sheet separately from the articles inside the bag main body 2. In addition, because the one seal portion 240 and the other seal portion 250 overlap at both ends in the second direction Y, strength in the third direction Z can be ensured, preventing, for example, the bag from tearing and exposing the contained articles.

[0047] In this embodiment, the one end extension portion 212 is longer in the second direction Y than the other end extension portion 213, so that an adhesive area with the rear main body portion 211 can be secured by the amount of the one through-hole A11 formed therein.

[0048] In this embodiment, when the one glue tab portion 210 and the back main body portion 211 are overlapped, a recess 2a is formed at the other end in the second direction Y of the bag main body 2 (the lower end in FIG. 1). Therefore, when an article is placed in the bag main body 2, the article can be placed without being caught at the other end in the second direction Y.

[0049] Next, a hanging bag 1 of a second embodiment will be described with reference to Figures 3 and 4. Here, when describing the hanging bag 1 of the second embodiment, a description of the same configuration as in the first embodiment will be omitted.

[0050] As shown in Fig. 3, in the hanging bag 1 of the second embodiment, one end 24 (the upper end in Fig. 3) of the bag body 2 in the second direction Y is open. Therefore, in the hanging bag 1 of the second embodiment, items are placed into the bag body 2 from the one end 24 side in the second direction Y. Furthermore, the hanging bag 1 of the second embodiment is configured to be longer in the first direction X than in the second direction Y.

[0051] The hanging bag 1 of the second embodiment does not have a portion corresponding to the one sealed portion 240 of the first embodiment. On the other hand, as shown in Fig. 3, the hanging bag 1 of the second embodiment has an adhesive portion 3 and a window portion 4 in addition to the bag body 2 and the other sealed portion 250 described in the first embodiment.

[0052] The bag body 2 of the second embodiment is similar to that of the first embodiment and includes a front surface portion 20 and a back surface portion 21. As shown in Fig. 4, the front surface portion 20 includes a front main body portion 200. The front main body portion 200 of the second embodiment is formed in a rectangular shape that is longer in the first direction X than in the second direction Y.

[0053] The front main body portion 200 is formed with a first through portion A100 and a second through portion A101 as front through portions (no reference numerals are assigned in the second embodiment) that penetrate in the third direction Z. The first through portion A100 is formed in a portion of the front main body portion 200 that overlaps with the one end extension portion 212 when the one end extension portion 212 is overlapped on the front main body portion 200. The first through portion A100 is configured as a circular hole that penetrates the front main body portion 200 in the third direction Z. The first through portion A100 is also arranged in the center in the first direction X. Furthermore, the first through portion A100 in this embodiment is arranged between front and back adhesive portions 32, 32, which will be described later, in the first direction X.

[0054] As shown in FIG. 4, the second through portion A101 is formed closer to the other end in the second direction Y (toward the lower end in FIG. 4) than the first through portion A100. The second through portion A101 of this embodiment penetrates the front main body portion 200 in the third direction Z and is configured as a rectangular hole that is longer in the second direction Y than in the first direction X. The second through portion A101 of this embodiment is disposed between the front and back adhesive portions 32, 32 described below in the first direction X. In this embodiment, the second through portion A101 is disposed near the other end in the second direction Y.

[0055] The back surface portion 21 of the second embodiment includes a back main body portion 211, one adhesive margin portion 210, another adhesive margin portion 214, and one end extension portion 212. As shown in Fig. 4, the one adhesive margin portion 210 of the second embodiment is provided continuing from the other end of the front main body portion 200 in the first direction X (the left end in Fig. 4), and the other adhesive margin portion 214 is provided continuing from one end of the front main body portion 200 in the first direction X (the right end in Fig. 4). The one adhesive margin portion 210 and the other adhesive margin portion 214 are overlapped on the front main body portion 200 from the back surface side in the third direction Z by folding the first fold a.

[0056] The rear main body portion 211 is provided continuously from the other end of the front main body portion 200 in the second direction Y (the lower end in FIG. 4 ). In the second embodiment, the one glue margin portion 210 and the other glue margin portion 214 are overlapped on the front main body portion 200, and the rear main body portion 211 is overlapped and adhered to the one glue margin portion 210 and the other glue margin portion 214. Therefore, the length of the rear main body portion 211 in the second embodiment is set so that it overlaps with the one glue margin portion 210 and the other glue margin portion 214. On the other hand, the length of the rear main body portion 211 in the second embodiment is set so that it overlaps with the one end extension portion 212. The rear main body portion 211 in the second embodiment is shorter in the second direction Y than the front main body portion 200. Therefore, as shown in Figure 3, in the second embodiment, when the front main body portion 200 and the rear main body portion 211 are stacked, the front main body portion 200 extends further toward one end (the upper end in Figure 3) in the second direction Y than the rear main body portion 211.

[0057] A back-through portion A12 is formed in the rear main body portion 211. This back-through portion A12 is formed in a portion of the rear main body portion 211 that overlaps with the first front-through portion A100 when the rear main body portion 211 is overlapped on the front main body portion 200. Therefore, when the rear main body portion 211 and the front main body portion 200 are overlapped, the back-through portion A12 and the first front-through portion A100 communicate with each other. The back-through portion A12 in this embodiment is configured as a circular hole with a larger diameter than the first front-through portion A100 and the one-side through portion A11.

[0058] In the second embodiment, the rear main body portion 211 is formed with a tear assisting portion 6 that assists in opening the hanging bag 1. This tear assisting portion 6 is configured in the shape of a broken line by intermittently cutting the rear main body portion 211. The tear assisting portion 6 in this embodiment is formed in the second direction Y on both sides of the first direction X, and is also formed in the first direction X so as to connect both sides of the first direction X. The tear assisting portion 6 in this embodiment is formed in the second direction Y on the second fold b side (upper side in FIG. 4 ) of the rear penetration portion A12.

[0059] Furthermore, the other end of the tear assisting part 6 in the first direction X (the left end in FIG. 4 ) is configured as a tear initiation part 51 that triggers opening. That is, the tear initiation part 51 in this embodiment is formed at an intersection of the first direction X and the second direction Y of the tear assisting part 6, and is inclined with respect to the first direction X and the second direction Y. By pulling this tear initiation part 51, the back main body part 211 is broken in the first direction X and the second direction Y along the tear assisting part 6.

[0060] As in the first embodiment, the one-end extending portion 212 is provided continuous from one end of the front main body portion 200 in the second direction Y (the upper end in FIG. 4). A one-end through-portion A11 is formed in the one-end extending portion 212. This one-end through-portion A11 is configured as a circular hole with a larger diameter than the first front through-portion A100. This one-end through-portion A11 is configured to communicate with the back through-portion A12 when the one-end extending portion 212 is placed on the back main body portion 211. Furthermore, in this embodiment, a tongue portion 50 is formed at the other end in the first direction X (the left end in FIG. 4) of the one-end extending portion 212, which is used when opening the hanging bag 1. Specifically, the tongue portion 50 overlaps with the tear start end 51 when the one-end extending portion 212 is placed on the back main body portion 211. Then, when the hanging bag 1 is opened, the tongue portion 50 is pulled together with the tear start end 51. The tongue portion 50 of this embodiment is formed by bending the other end of the one-end extension portion 212 in the first direction X into a substantially S-shape.

[0061] The adhesive part 3 is for adhering the front main body part 200, the rear main body part 211, and the one-end extending part 212. As shown in Fig. 4, the adhesive part 3 of this embodiment includes a front-back adhesive part 32 that adheres the front main body part 200 and the rear main body part 211 together, a sealing adhesive part 30 that adheres the rear main body part 211 and the one-end extending part 212 together, and an auxiliary adhesive part 31 that adheres the front main body part 200 and the one-end extending part 212 together.

[0062] The front-back adhesive portion 32 is for adhering the front main body portion 200 and the rear main body portion 211 that are overlapped in the third direction Z. As shown in Fig. 3, the front-back adhesive portion 32 of this embodiment adheres the front main body portion 200 and the rear main body portion 211 to one end side and the other end side in the first direction X of the front-penetrating portion. Furthermore, the front-back adhesive portion 32 is arranged on the front-penetrating portion side in the first direction X of the one glue margin portion 210 and the other glue margin portion 214 that are overlapped on the front main body portion 200. Furthermore, as shown in Fig. 4, the front-back adhesive portion 32 of this embodiment is arranged in the second direction Y across the front main body portion 200 and the rear main body portion 211.

[0063] The sealing adhesive portion 30 includes a back adhesive portion 301 formed on the back main body portion 211 and an extended adhesive portion 300 formed on the one end extending portion 212. In this embodiment, the back adhesive portion 301 is formed between the back penetration portion A12 and the breaking assist portion 6 in the second direction Y. The extended adhesive portion 300 is arranged so as to overlap the back adhesive portion 301 when the one end extending portion 212 is overlapped on the back main body portion 211. In addition, in this embodiment, the extended adhesive portion 300 is formed on the one end side in the second direction Y relative to the one penetration portion A11. In this embodiment, the back adhesive portion 301 and the extended adhesive portion 300 are formed to have approximately the same length in the first direction X. In addition, the sealing adhesive portion 30 in this embodiment is configured as adhesive glue.

[0064] The auxiliary adhesive portion 31 is for adhering the front main body portion 200 and the one-end extending portion 212 when the front main body portion 200 and the one-end extending portion 212 are overlapped. As shown in FIG. 4 , the auxiliary adhesive portion 31 of this embodiment includes an auxiliary front adhesive portion 311 provided on the front main body portion 200 and an auxiliary one-end adhesive portion 310 provided on the one-end extending portion 212. The auxiliary front adhesive portion 311 and the auxiliary one-end adhesive portion 310 are configured to overlap and adhere to the front main body portion 200 and the one-end extending portion 212 when they are overlapped. Furthermore, in this embodiment, the auxiliary front adhesive portion 311 and the auxiliary one-end adhesive portion 310 are arranged between the one-side through-portion A11 and the first front through-portion A100 in the second direction Y. Therefore, when the front main body portion 200 and the one end extension portion 212 of this embodiment are overlapped, the auxiliary front adhesive portion 311 and the auxiliary one end adhesive portion 310 are adhered to one end side of the through hole A1 in the second direction Y. The auxiliary adhesive portion 31 of this embodiment is made of adhesive glue.

[0065] The hanging reinforcement portion is intended to reinforce the hanging portion A. In the hanging bag 1 of this embodiment, the hanging reinforcement portion is configured by the auxiliary adhesive portion 31. That is, the auxiliary adhesive portion 31 bonds the front main body portion 200 to the one-end extending portion 212 at one end side in the second direction Y relative to the through hole A1 (the upper end side in FIG. 3 ), thereby preventing the bag body 2 from expanding in the third direction Z. Therefore, the hanging reinforcement portion of this embodiment prevents the bag body 2 from expanding in the third direction Z at the one end side in the second direction Y relative to the through hole A1 by bonding the front main body portion 200 to the one-end extending portion 212. Therefore, for example, when the hanging bag 1 is hung from a hook or the like via the through hole A1, the bag body 2 at the one end side in the second direction Y relative to the through hole A1 is prevented from tearing due to the weight of the hanging bag 1.

[0066] As shown in Fig. 3, the window 4 is for checking the inside of the hanging bag 1. This window 4 is provided in the front main body 200. The window 4 in this embodiment is formed by attaching a window main body 40 to the second through-hole A101. Specifically, the window main body 40 in this embodiment is formed from a transparent plastic sheet or translucent glassine paper.

[0067] The other seal portion 250 of the second embodiment seals one end 24 of the bag body 2 in the second direction Y. Therefore, in the second embodiment, the one end extending portion 212 is configured as the other seal portion 250 described in the first embodiment. That is, by folding the second fold b, the one end extending portion 212 and the rear main body portion 211 overlap, and by bonding the extended adhesive portion 300 and the rear side adhesive portion 301, the rear main body portion 211 and the one end extending portion 212 are bonded to each other, thereby configuring the other seal portion 250.

[0068] 3, the hanging portion A of the second embodiment is configured as a through hole A1 that penetrates the front main body portion 200, the rear main body portion 211, and the one-end extension portion 212 in the third direction Z. Specifically, the through hole A1 is configured by communicating the first front through portion A100, the one-side through portion A11, and the rear through portion A12.

[0069] When forming the hanging bag 1 of the second embodiment using the above configuration, the first fold a is folded to overlap the one adhesive margin portion 210 and the other adhesive margin portion 214 on the front main body portion 200, and then the second fold b is folded to overlap the back main body portion 211 on the front main body portion 200, the one adhesive margin portion 210, and the other adhesive margin portion 214. This allows the first front penetration portion A100 and the back penetration portion A12 to communicate in the third direction Z. Furthermore, when the back main body portion 211 is overlapped on the front main body portion 200, the one adhesive margin portion 210, and the other adhesive margin portion 214, the back main body portion 211 is adhered to the one adhesive margin portion 210 and the other adhesive margin portion 214, and the back main body portion 211 is adhered to the front main body portion 200 via the front and back adhesive portions 32, 32. This closes one end 22 and the other end 23 in the first direction X and the other end 25 in the second direction Y.

[0070] Next, an article is placed inside the bag main body 2 from the open one end 24 in the second direction Y, and the second fold b is folded to overlap the one end extension portion 212 with the front main body portion 200 and the rear main body portion 211. As a result, the one end through-portion A11 communicates with the rear through-portion A12 and the first front through-portion A100 in the third direction Z. Furthermore, as the one end extension portion 212 overlaps the front main body portion 200 and the rear main body portion 211, the auxiliary front adhesive portion 311 and the auxiliary one end adhesive portion 310 are adhered, and the extending adhesive portion 300 and the rear side adhesive portion 301 are adhered. In this way, the hanging bag 1 of the second embodiment is formed.

[0071] As described above, according to the hanging bag 1 of the second embodiment, the hanging portion A is configured as a through hole A1 that penetrates the one end extension portion 212, the front main body portion 200, and the rear main body portion 211 in the third direction Z. Therefore, for example, when hanging the hanging bag 1 by passing a hook through the through hole A1, the hanging bag 1 can be supported by the one end extension portion 212, the front main body portion 200, and the rear main body portion 211, so that the hanging bag 1 can be hung securely.

[0072] Furthermore, in the second embodiment, a hanging reinforcement portion is formed by bonding the one end extension portion 212 and the front main body portion 200 with the auxiliary adhesive portion 31 on one end side in the second direction Y from the through hole A1. Therefore, on one end side in the second direction Y from the through hole A1, the auxiliary adhesive portion 31 can prevent the front main body portion 200 and the one end extension portion 212 from separating, and the hanging reinforcement portion can prevent the one end side in the second direction Y from being torn due to the weight of the hanging bag 1 or the like.

[0073] Furthermore, in this embodiment, the front main body portion 200 and the rear main body portion 211 are bonded together at the front and rear adhesive portions 32, 32. Therefore, when an item is placed inside the bag main body 2, the front main body portion 200 and the rear main body portion 211 are prevented from separating at both ends in the first direction X, thereby maintaining the shape of the hanging bag 1, and the bag main body 2 is allowed to bulge in the third direction Z between the front and rear adhesive portions 32, 32, thereby creating a three-dimensional effect.

[0074] Also, in the second embodiment, a window portion 4 is provided in the front main body portion 200. Therefore, it is possible to check the items inside the bag main body 2 through the window portion 4. In particular, in this embodiment, when the hanging bag 1 is hung, it is possible to check the items inside the hanging bag 1 through the front main body portion 200 on the front side. Furthermore, because the second through portion A101 that constitutes the window portion 4 is located near the other end in the second direction Y (the lower end in FIG. 3), it is easy to check the items that have moved to the other end in the second direction Y due to their own weight or the like inside the bag main body 2.

[0075] Next, a hanging bag 1 according to a third embodiment will be described. In describing the hanging bag 1 according to the third embodiment, descriptions similar to those of the hanging bag 1 according to the first and second embodiments will be omitted.

[0076] As shown in Fig. 5, the hanging bag 1 of the third embodiment is configured so that the second direction Y is longer than the first direction X. This hanging bag 1 is open at one end 24 in the second direction Y, and articles are placed in the bag main body 2 from the side of the open end 24 in the second direction Y. The hanging bag 1 of the third embodiment also includes the bag main body 2, one sealed portion 240, the other sealed portion 250, a separation assisting portion c (shown in Fig. 8), an adhesive portion 3, a window portion 4, and a hanging portion A.

[0077] The bag body 2 includes a front surface portion 20 and a back surface portion 21 that are disposed opposite each other in the third direction Z. As shown in FIG. 8 , the front surface portion 20 of the third embodiment includes a front main body portion 200, similar to the first and second embodiments. The front main body portion 200 is formed with a first through-hole A100 and a second through-hole A101 that penetrate the front main body portion 200 in the third direction Z as front through-holes (not indicated by reference numerals). The first through-hole A100 of the third embodiment is configured as a circular hole that penetrates the front main body portion 200 in the third direction Z. The first through-hole A100 is positioned so as to communicate with the back through-hole A12 when the front main body portion 200 and the back main body portion 211 are overlapped in the third direction Z. The second through-hole A101 of the present embodiment is configured as a circular hole with a larger diameter than the first through-hole A100. The second through portion A101 is located at the other end 25 in the second direction Y (the lower end in FIG. 8) than the first through portion A100. The second through portion A101 in this embodiment is formed on the other end side in the first direction X (the right end in FIG. 8). In this embodiment, the second through portion A101 is configured as a window portion 4 for checking the inside of the bag body 2.

[0078] As shown in Figure 8, the back surface portion 21 includes a front one end extension portion 217 that is continuous from one end of the front main body portion 200 in the second direction Y (the upper end of Figure 8), an other end margin portion 214 that is continuous from the front one end extension portion 217 and one end of the front main body portion 200 in the first direction X (the right end of Figure 8), a back plate portion 21a that is continuous from the other end of the front main body portion 200 in the first direction X (the left end of Figure 8), and an other end extension portion 213 that is continuous from the other end of the front main body portion 200 in the second direction Y (the lower end of Figure 8).

[0079] The front one end extending portion 217 is disposed at one end in the second direction Y of the front main body portion 200 (the upper end in FIG. 8). This front one end extending portion 217 is connected in the first direction X to an extended glue margin portion 215 and a back one end extending portion 212, which will be described later, with a separation assisting portion c, which will be described later, sandwiched therebetween. The front one end extending portion 217 is provided with a front one side through-portion A13a that passes through the front one end extending portion 217 in the third direction Z. This front one side through-portion A13a is disposed so as to communicate with the back one side through-portion A13b when the front one end extending portion 217 and the back one end extending portion 212 are overlapped.

[0080] 8, in the third embodiment, the other glue tab 214 includes an extended glue tab 215 that overlaps with the front end extended portion 217, and a main body glue tab 216 that overlaps with the front main body portion 200. That is, in the third embodiment, when the first fold a is folded, the extended glue tab 215 overlaps with the front end extended portion 217, and the main body glue tab 216 overlaps with the front main body portion 200.

[0081] As shown in FIG. 8, the back plate portion 21a includes a back main body portion 211 that forms the back surface in the third direction Z, and a back one-end extension portion 212 that continues from the back main body portion 211. The back main body portion 211 is formed to have approximately the same length as the front main body portion 200 in the first direction X and the second direction Y. Therefore, when folded along the first fold a, the back main body portion 211 closely overlaps the front main body portion 200. In addition, the back main body portion 211 of this embodiment is formed with a back penetration portion A12 that penetrates the back main body portion 211 in the third direction Z. This back penetration portion A12 is arranged to communicate with the first front penetration portion A100. In addition, the back penetration portion A12 of this embodiment is formed longer toward the other end side in the second direction Y (the lower end side in FIG. 8) than the first front penetration portion A100.

[0082] The rear one end extension portion 212 is provided from one end of the rear main body portion 211 in the second direction Y (the upper end in FIG. 8 ). In this embodiment, the rear one end extension portion 212 is formed to be substantially the same as the rear main body portion 211 in the first direction X. Therefore, when the rear one end extension portion 212 is folded along the second fold line b and overlapped on the rear main body portion 211, the rear one end extension portion 212 overlaps the rear main body portion 211 exactly. The rear one end extension portion 212 has a rear one through-portion A13b penetrating in the third direction Z. As shown in FIG. 5 , this rear one through-portion A13b is arranged to communicate with the front one through-portion A13a when the rear one end extension portion 212 is overlapped on the front one end extension portion 217 (not shown in FIG. 5 ). In addition, in this embodiment, the rear one through-portion A13b is configured as a circular hole that is longer in the first direction X than the front one through-portion A13a.

[0083] As shown in Fig. 8, the other-end extending portion 213 is provided from the other end of the front main body portion 200 in the second direction Y (the lower end in Fig. 8). This other-end extending portion 213 overlaps with the rear main body portion 211 when the front main body portion 200 is folded along the second fold line b. That is, in this embodiment, when the front main body portion 200 and the rear main body portion 211 are overlapped, the other-end extending portion 213 overlaps with the rear main body portion 211, thereby sealing the other end portion 25 of the bag body 2 in the second direction Y. Therefore, as shown in Figs. 5 and 7, the other-end extending portion 213 constitutes one sealing portion 240.

[0084] The other sealing portion 250 of the third embodiment is composed of a front end extending portion 217, a rear end extending portion 212, and an extended glue margin portion 215, which are overlapped in the third direction Z. That is, in the third embodiment, from the state shown in Fig. 5, the second fold b is folded to overlap the front end extending portion 217 (not shown in Fig. 5), the extended glue margin portion 215 overlapping the front end extending portion 217, and the rear end extending portion 212 on the rear main body portion 211, thereby sealing one end 24 of the bag main body 2 in the second direction Y, as shown in Fig. 6.

[0085] As shown in Fig. 5, the hanging portion A of the third embodiment is configured as a through hole A1, similar to the first and second embodiments. As shown in Fig. 6, this through hole A1 is configured by communication between a first front through portion A100, a back through portion A12, a front one through portion A13a, and a back one through portion A13b.

[0086] The separation assisting portion c is configured to be able to separate the extension portion in the third direction Z. This separation assisting portion c is configured as a dashed-line perforation extending intermittently in the second direction Y between the front one end extension portion 217 and the back one end extension portion 212 and the extended glue margin portion 215. Furthermore, the separation assisting portion c in this embodiment is continuous from the first fold a in the second direction Y. Therefore, in a state in which the front one end extension portion 217, the extended glue margin portion 215, and the back one end extension portion 212 are overlapped along the first fold a, the front one end extension portion 217 and the back one end extension portion 212 can be separated in the third direction Z by cutting the separation assisting portion c at both ends in the first direction X (the right end and the left end in FIG. 5 ). Note that the separation assisting portion c in this embodiment is configured to extend along the second direction Y.

[0087] In this embodiment, the rear one end extending portion 212 has an adhesive portion 3 formed thereon, which adheres the rear one end extending portion 212 to the rear main body portion 211 and the front main body portion 200. This adhesive portion 3 is disposed closer to one end in the second direction Y (the upper end side in FIG. 8 ) than the rear one through-hole A13b. Furthermore, the adhesive portion 3 in this embodiment is disposed so as to overlap the rear through-hole A12 and the rear main body portion 211 when the rear one end extending portion 212 is overlapped on the rear main body portion 211.

[0088] In the bag body 2 of this embodiment, from the state shown in Fig. 8, the first fold a is folded, the other glue tab 214 overlaps the back side of the front main body portion 200, and the back plate portion 21a is overlapped and bonded to the back side of the other glue tab 214. Thereafter, the second fold b is folded, and the other front end extension 213 is overlapped and bonded to the back main body portion 211. As a result, as shown in Fig. 5, the one end 22 and the other end 23 in the first direction X and the other end 25 in the second direction Y of the bag body 2 are sealed, and the one end 24 in the second direction Y is opened. Furthermore, as the front main body portion 200 and the back main body portion 211 overlap, and the one back end extension 212 and the one front end extension 217 overlap, the one front through-hole A13a and the one back through-hole A13b communicate with each other, and the first front through-hole A100 and the back through-hole A12 communicate with each other.

[0089] Then, after placing an article into the bag main body 2 from the open one end 24 in the second direction Y, the second fold b is folded and the one back end extension 212 is overlapped on the back main body portion 211. At this time, as shown in Figures 6 and 7, the adhesive portion 3 is adhered to the back main body portion 211 and also adhered to the front main body portion 200 via the back penetration portion A12. Therefore, the other sealing portion 250 seals the one end 24 in the second direction Y of the bag main body 2. Furthermore, by overlapping the one back end extension 212 on the back main body portion 211, the one front penetration portion A13a, the one back penetration portion A13b, the first front penetration portion A100, and the back penetration portion A12 are communicated with each other.

[0090] As described above, according to the third embodiment, as shown in FIG. 6, the second fold b is folded so that the front end extension portion 217 and the back end extension portion 212 overlap the front main body portion 200 and the back main body portion 211, and the other sealing portion 250 can seal one end portion 24 of the bag main body 2 in the second direction Y.

[0091] Furthermore, in the hanging bag 1 of the third embodiment, when opening one end 24 of the bag main body 2 in the second direction Y, the separation assisting parts c, c are broken and the back end extension part 212 and the front end extension part 217 are separated in the third direction Z, causing the front end extension part 217 to stand up on one end side in the second direction Y, as shown in Fig. 7. Therefore, in the hanging bag 1 of this embodiment, once the separation assisting parts c, c are broken to open one end 24 in the second direction Y, it can be seen that the one end 24 of the bag main body 2 in the second direction Y has been opened.

[0092] In the third embodiment, the separation assisting portions c, c are arranged in the second direction Y, so that the one end 24 of the bag body 2 in the second direction Y can be easily opened.

[0093] In addition, in the third embodiment, the front one-side through-hole A13a, the back one-side through-hole A13b, the first front one-side through-hole A100 and the back one-side through-hole A12 are connected to form a through-hole A1, so that the hanging bag 1 can be supported by the four parts: the front one-end extension portion 217, the back one-end extension portion 212, the back main body portion 211 and the front main body portion 200.

[0094] In the third embodiment, as shown in Fig. 6, the adhesive portion 3 is adhered to the front main body portion 200 via the back through-hole A12. Therefore, as shown in Fig. 7, the front surface portion 20 (not shown in Fig. 7) and the back surface portion 21 are adhered (joined) in the third direction Z on the other end side (lower end side) in the second direction Y of the through-hole A1. This prevents the article in the bag main body 2 from rising in the second direction Y so as to overlap the through-hole A1.

[0095] Furthermore, in the third embodiment, the second through portion A101 constituting the window portion 4 is located closer to the other end in the second direction Y (the lower end in FIG. 8) than the first through portion A100, at the other end 25 in the second direction Y. Furthermore, this second through portion A101 is formed on the other end side in the first direction X (the right end in FIG. 8). Therefore, in this embodiment, since the second through portion A101 is formed near a corner of the hanging bag 1, the hanging bag 1 is less likely to be distorted.

[0096] The hanging bag of the present invention is not limited to the first to third embodiments described above, and various modifications are possible. For example, in the third embodiment, the article in the bag body 2 is prevented from rising in the second direction Y to prevent the through-hole A1 from overlapping with the article. However, in the first and second embodiments, the same technique as in the third embodiment may be used to prevent the through-hole A1 from overlapping with the article. In this case, the through-hole of the member disposed in the center in the third direction Z may be configured to be larger toward the lower end than the other through-holes. Alternatively, the article in the bag body 2 may be prevented from rising in the second direction Y by a method other than the above, for example, by bonding the front surface portion 20 and the back surface portion 21 in the third direction Z at a predetermined distance below the through-hole A1.

[0097] In the above first embodiment, a case was described in which one end 24 in the second direction Y is closed and the other end 25 is open, but this is not limited to this. For example, the other end 25 in the second direction Y may be closed and one end 24 may be open.

[0098] In the first embodiment described above, the length of one of the adhesive margins 210 in the first direction X is configured to be shorter than the distance from the other end of the front main body 200 in the first direction X to the front-penetrating portion A10, thereby preventing the front-penetrating portion A10 from being blocked. However, this is not limited to this, and for example, the length of the one of the adhesive margins 210 in the first direction X may be set so as to block only at least a portion of the front-penetrating portion A10.

[0099] Furthermore, in the hanging bag 1 of the first embodiment described above, a through hole A1 is formed as the hanging portion A at one end 24 in the second direction Y, but the present invention is not limited to this, and the hanging portion A may be formed as a through hole A1 that penetrates the other end 25 of the bag body 2 in the second direction Y. In this case, it is considered that a through hole A1 is formed that penetrates the other end extending portion 213. That is, the front through portion A10 is formed on the other end 25 side of the front main body portion 200 in the second direction Y, the back through portion A12 is formed in the back main body portion 211 so as to communicate with the front through portion A10 when the back main body portion 211 is overlapped on the front main body portion 200, and the other through portion that communicates with the front through portion A10 and the back through portion A12 is formed in the other end extending portion 213.

[0100] Furthermore, in the above first to third embodiments, the through hole A1 serving as the hanging portion A is described as being circular, but the present invention is not limited to this and may be, for example, a rectangular or keyhole-shaped through hole. Furthermore, as shown in Fig. 9, for example, the through hole A1 may be comprised of a main body through portion A2 that penetrates the hanging bag 1 in the third direction Z between both ends of the hanging bag 1 in the first direction X and the second direction Y, a first through portion A3 that extends from the main body through portion A2 in the first direction X, and a second through portion A4 that extends from the first through portion A3 to the end in the second direction Y. This makes it possible to hang the hanging bag 1 by hooking it onto the hook by passing a hook through the main body through portion A2 from the second through portion A4, via the first through portion A3, and then

[0101] Furthermore, in the first to third embodiments, the through portions constituting the through hole A1 are configured to have different diameters, but this is not limiting, and for example, all of the through portions may have the same diameter.

[0102] Furthermore, in the bag body 2 of the first to third embodiments described above, a through hole A1 was formed as the hanging portion A, but this is not limited to this, and for example, instead of the through hole A1, a hook may be attached as the hanging portion A.

[0103] Furthermore, in the above first to third embodiments, the one end 24 or the other end 25 in the second direction Y is sealed by the one end extension portion 212 or the other end extension portion 213 overlapping the front main body portion 200 or the back main body portion 211, but this is not limiting, and for example, the one end 24 or the other end 25 in the second direction Y may be sealed by bonding the front portion 20 and the back portion 21 together within the bag body 2. That is, in this case, the other sealing portion 250 is configured as an adhesive portion that bonds the front portion 20 and the back portion 21 together.

[0104] In addition, in the above first to third embodiments, the bag body 2 was composed of a front portion 20 and a back portion 21, but for example, the bag body 2 may be configured with a gusset in the third direction Z, which is the thickness direction.

[0105] Furthermore, in the third embodiment, the separation assisting portions c are disposed at both ends in the first direction X, but this is not limiting, and for example, they may be formed between both ends in the first direction X. That is, in this case, it is considered that the separation assisting portions c are not continuous with the first fold a in the second direction Y. Furthermore, while the separation assisting portions c in the third embodiment are configured to extend along the second direction Y, this is not limiting, and for example, they may be inclined toward the first direction X as they progress in the second direction Y.

[0106] Furthermore, in the third embodiment described above, the separation assisting portion c is configured as a broken-line perforation extending intermittently in the second direction, but this is not limited thereto, and the separation assisting portion c may be configured, for example, as an adhesive portion provided in the front end extension portion 217 for peelably adhering the front end extension portion 217 and the back end extension portion 212 together.

[0107] In the second embodiment, the case where the hanging reinforcement portion is formed by bonding the front main body portion 200 and the one-end extending portion 212 with the auxiliary adhesive portion 31 at one end side in the second direction Y relative to the through hole A1 (the upper end side in FIG. 3 ) has been described. However, the present invention is not limited to this. For example, the front main body portion 200 or the one-end extending portion 212 may be thickened in the third direction Z at one end side in the second direction Y relative to the through hole A1, thereby bringing the front main body portion 200 and the one-end extending portion 212 closer to each other, thereby increasing strength. Furthermore, in forming the hanging reinforcement portion, the front main body portion 200 and the one-end extending portion 212 do not need to be bonded with the auxiliary adhesive portion 31. For example, the front main body portion 200 and the one-end extending portion 212 may be bonded (joined) without the auxiliary adhesive portion 31 interposed therebetween.

[0108] In the second and third embodiments, the window portion 4 was formed by penetrating the front main body portion 200 in the third direction Z, but this is not limited to this. For example, the front main body portion 200 may be made of a paper material that is transparent in the third direction Z.

[0109] Furthermore, in the second embodiment described above, the adhesive portion 3 is provided with a front-back adhesive portion 32 in order to adhere the front main body portion 200 and the rear main body portion 211 in the third direction Z, but this is not limited to this, and for example, the adhesive portion 3 may not be provided with a front-back adhesive portion 32 in order not to adhere the front main body portion 200 and the rear main body portion 211 in the third direction Z.
