JP7777438B2 - Hanging bag - Google Patents

Description

For example, this relates to hanging bags that can be hung in storefronts and other locations with items inside.

Patent Document 1 describes a packaging bag that is a hanging bag. 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, sealing the peripheries of the front sheet and the back sheet together, and providing a sealing line that crosses the bag body at a predetermined distance below the top end. This forms a bag portion below the sealing line for storing products, and a header above the sealing line for providing a hanging hole.

Utility Model Registration No. 3082838

However, because the packaging bag described in Patent Document 1 uses a film laminated with oriented polypropylene and unoriented polypropylene, if this packaging bag is disposed of, for example, by being landfilled or dumped into the ocean, it will not decompose for a long period of time and will remain underground or in the ocean. As a result, the packaging bag described in Patent Document 1 could potentially cause a burden on the environment.

The present invention therefore provides a hanging bag that can contribute to reducing environmental impact.

The present invention relates to a hanging bag comprising a bag-shaped bag body in which both ends in a first direction and one of the ends in a second direction perpendicular to the first direction are closed, and the other of the ends is open; and a sealing part on the other end of the bag body that is capable of sealing the open other end; the bag body has a hanging part formed on the one end or the other end for hanging the bag body; and the bag body is made of a paper material.

With this configuration, for example, the item can be placed inside the bag body through the open other part, and by sealing the other part with the other sealing part, the item can be prevented from coming out of the other part. The bag body can also be hung by the hanging part. In addition, because the bag body is made of paper, for example, the bag body can be recycled as a paper resource when disposed of, thereby contributing to reducing environmental impact.

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

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

Furthermore, in the hanging bag, the bag body may have 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 including the other portion, the other portion of at least one of the front portion and the back portion having an extending portion extending from the other portion in the second direction, the extending portion configured to be bent toward the opening side of the other portion in the third direction, the other sealing portion including the extending portion and configured to seal the opening of the other portion when the extending portion is folded, and the hanging portion may be configured as a through hole penetrating the extending portion, the front portion, and the back portion in the third direction when the extending portion folded in the third direction overlaps the front portion and the back portion.

With this configuration, the hanging portion is configured as a through hole that penetrates the extension portion, the front portion, and the back portion in the third direction. Therefore, when the hanging bag is hung through the through hole using a hook provided on a display stand or the like, the hanging bag can be supported by the extension portion, the front portion, and the back portion, making it less likely for the through hole to deform due to the bag's weight, and allowing the bag to be hung securely.

Furthermore, in the hanging bag, the extension portion may be formed on the other portion of one of the front and back portions, and one of the front and back portions and the folded extension portion may be joined in the third direction on the other portion side of the through hole, thereby forming a hanging reinforcement portion that reinforces the hanging portion.

With this configuration, one of the front and back surfaces is joined to the folded extension in the third direction on the other side of the through hole, forming a hanging reinforcement that reinforces the hanging portion. Therefore, 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 can prevent the strength of the through hole from decreasing.

Furthermore, in the hanging bag, the bag body may have 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 including the other portion, the other portions of the front portion and the back portion having extending portions extending in the second direction from the other portions, the extending portions formed on the other portions of the front portion and the back portion being connected on both sides in the first direction and configured to be bendable to one side or the other in the third direction so as to overlap the front portion and the back portion, the other sealing portion including the extending portion and 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 may have a separation assisting portion formed to separate the extending portions of the front portion and the back portion in the third direction.

With this configuration, the extension portion is folded so that it overlaps the front and back surfaces, allowing the other sealing portion to seal the other surface. Furthermore, when opening the other surface, the separation assisting portion separates the extension portions of the front and back surfaces in a third direction, allowing the other surface to be opened.

Furthermore, in the hanging bag, the bag body may have a front surface portion and a back surface portion arranged opposite each other in a third direction perpendicular to the first direction and the second direction, the front surface portion and the back surface portion including the one portion and the other portion, the hanging portion being configured as a through hole penetrating the front surface portion and the back surface portion in the third direction in one of the one portion and the other portion, and the front surface portion and the back surface portion being configured to be joined in the third direction on the other side of the one portion and the other portion relative to the through hole.

With this configuration, the front surface portion and the back surface portion are joined in the third direction on the other side of the through hole, so that, for example, if an item is stored in the bag body and moves within the bag body, the item can be prevented from overlapping with the through hole.

As described above, the hanging bag of the present invention can contribute to reducing environmental impact.

The following describes a first embodiment of the hanging bag of the present invention. The hanging bag is intended to be hung and displayed in a store, for example, with an item inside.

In the following description, the width direction of the hanging bag will be referred to as the "first direction X," the length direction of the hanging bag will be referred to as the "second direction Y," and the thickness direction of the hanging bag will be referred to as the "third direction Z." Furthermore, 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.

As shown in FIG. 1, the hanging bag 1 of the first embodiment comprises a bag body 2, a first sealing portion 240, and an opposite sealing portion 250. The bag body 2 is configured in a bag shape with a front portion 20 and a back portion 21 (described below) to accommodate an item. Here, "bag-shaped" refers to a structure in which two sheets, one on top of the other, are stacked and bonded together at their edges 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 so that one end 22 and 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.

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, as well as wrapping paper such as unbleached paper, semi-bleached paper, bleached paper, and semi-glossy paper. The thickness of the paper material, expressed in terms of 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 gluing the paper member shown in Figure 2 along folds 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 used to form the paper box is not included in the "paper" of this embodiment.

As shown in Figure 1, the bag body 2 has a front surface portion 20 and a back surface portion 21 that are arranged opposite each other in the third direction Z. In this embodiment, the front surface portion 20 forms the surface of the bag body 2 facing the third direction Z. As shown in Figure 2, this front surface portion 20 has a front body portion 200 that is arranged on the front side in the third direction Z.

The front main 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. A front through-hole portion A10 that penetrates in the third direction Z is formed in the front main body portion 200. The front through-hole portion A10 of this embodiment is formed on one end side (the upper end in Figure 2) of the front main body portion 200 in the second direction Y. The front through-hole portion A10 of this embodiment is formed as a circular hole. Note that the front through-hole A10 of this embodiment is positioned in the center in the first direction X.

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 first end extension portion 212 and an other end extension portion 213 extending from the front main body portion 200 in the second direction Y. As shown in FIG. 2, the first adhesive margin portion 210 extends 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 the front main body portion 200 when the first fold a is folded, and is adhered to the back main body portion 211 (described below) 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. This allows the first adhesive margin portion 210 to overlap the front main body portion 200 without protruding in the second direction Y. Furthermore, in this embodiment, when one glue tab 210 is placed on the front main body 200, the length of the one glue tab 210 in the first direction X is shorter than the distance from the other end of the front main body 200 to the front-penetrating portion A10 to prevent the front-penetrating portion A10 from being blocked.

As shown in FIG. 2 , the rear body portion 211 is provided continuous from one end (the right end in FIG. 2 ) of the front body portion 200 in the first direction X. When the rear body portion 211 is folded along the first fold a, it overlaps and is adhered to the one glue tab 210, which is overlapping the front body portion 200. Therefore, the length of the rear body portion 211 in the first direction X is set so that it overlaps the one glue tab 210. Furthermore, the rear body portion 211 in this embodiment is configured to be shorter than the front body portion 200 in both the first direction X and the second direction Y so as not to protrude beyond the front body portion 200. Meanwhile, the length of the rear 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 penetration portion A12 penetrating in the third direction Z is formed in the rear body portion 211. The back penetration portion A12 is formed in the back main body portion 211 so as to communicate with the front penetration portion A10 when the back main body portion 211 is stacked on top of the front main body portion 200. In this embodiment, the back penetration portion A12 is a circular hole with a larger diameter than the front penetration portion A10.

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

As shown in FIG. 2, the other-end extension 213 is continuous from the other end of the front main body 200 in the second direction Y (the lower end in FIG. 2). In this embodiment, the other-end extension 213 is configured so that its width in the first direction X narrows as it moves away from the front main body 200 in the second direction Y. This other-end extension 213 overlaps with the rear main body 211 when the second fold b is folded.

The one-side sealing portion 240 is the sealing portion on the closed side in the state before storing items 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 rear 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.

As shown in FIG. 1 , the other sealing portion 250 is a sealing portion configured to seal the other end 25 of the bag main body 2 in the second direction Y, which opens, before an item is placed inside the bag main body 2. In this embodiment, when an item (e.g., a writing implement such as a mechanical pencil or a ballpoint pen refill) is placed inside the bag main body 2 from the other end 25 in the second direction Y, the second fold b is folded and the other end extension 213 is overlapped and adhered to the rear main body 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 213 is configured as the other sealing portion 250. Note that the other end extension 213 may be releasably adhered to the rear main body 211 to facilitate removal of the item from the bag main body 2.

As shown in FIG. 1, the hanging portion A is used to hang the bag body 2. In this embodiment, the hanging portion A is configured by connecting the front through-hole A10, the one-side through-hole A11, and the back through-hole A12. Therefore, in this embodiment, the hanging portion A 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.

In this embodiment, the bag body 2 is folded along the first fold a from the unfolded state shown in FIG. 2, so that the first glue tab 210 overlaps the front body portion 200, and the rear body portion 211 overlaps and adheres to the first glue tab 210, thereby closing one end 22 and the other end 23 in the first direction X. In this embodiment, the first glue tab 210 is configured to become shorter in the second direction Y as it moves away from the front body portion 200 in the first direction X, and the rear body portion 211 is configured to be shorter than the front body portion in the second direction Y. Therefore, as shown in FIG. 1, when the first glue tab 210 and the rear body portion 211 overlap, a recess 2a is formed at the other end of the bag body 2 in the second direction Y (the lower end in FIG. 1) that is recessed toward one end in the second direction Y. 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.

Then, by folding the second fold b, the one-end extension 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, forming a bag main body 2 in which the one end 22 in the first direction X, the other end 23, and the one end 24 in the second direction Y are closed, as shown in FIG. 1. Furthermore, the one-side through-portion A11, the back through-portion A12, and the front through-portion A10 communicate with each other, forming a through hole A1 that penetrates the bag main body 2 in the third direction Z.

After that, items are placed into the bag body 2 from the other end 25 side in the second direction Y, and the second fold b is folded so that the other end extension 213 overlaps and adheres to the back body portion 211. As a result, in this embodiment, the other sealing portion 250 seals the other end 25 of the bag body 2 in the second direction Y. Furthermore, the front surface portion 20 and the back surface portion 21 overlap in the third direction Z.

As described above, according to this embodiment, in the state shown in Figure 1, items can be placed inside 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 of the bag body 2 in the second direction Y, so when placing items inside the bag body 2, they can be placed smoothly without getting caught on the hanging portion A. This can improve the workability when placing items into the bag body 2 using a machine, for example.

In addition, in this embodiment, by overlapping and adhering the other end extension portion 213 to the rear 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 prevents items from coming out of the bag main body 2.

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

In addition, in the first embodiment, the front main body portion 200, the rear main body portion 211, and the one-end extension portion 212 are stacked, 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, 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 extension portion 212. Therefore, for example, the through-hole A1 is less likely to deform due to the weight of the hanging bag 1, and the bag can be hung securely.

In addition, the hanging bag 1 of this embodiment is constructed by passing a through hole A1 serving as the hanging portion A through the bag body 2 in the third direction Z, making it easy to manufacture, compared to a configuration in which a separate hook is attached to the bag body 2, for example.

In addition, in this embodiment, the bag body 2 is constructed by folding and gluing a single sheet of paper material as shown in Figure 2, so when it is discarded, it can be reused as a paper resource, contributing to reducing the environmental impact.

Furthermore, because the hanging bag 1 of this embodiment has the bag body 2 formed by stacking the front surface portion 20 and the back surface portion 21, it is possible to prevent the bag from becoming bulky in the third direction Z, which is the thickness direction. In particular, because the hanging bag 1 of this embodiment is formed by stacking paper material having a thickness of 50 g/m2 to 150 g/m2, the assembly work required to make it capable of containing items, as with a paper box, is relatively less, and there is no need to reserve space in the thickness direction. For example, when storing or transporting in a warehouse, a larger number of hanging bags 1 can be stored compared to paper boxes.

In addition, in the hanging bag 1 of this embodiment, the length of the one glue tab 210 in the first direction X is shorter than the distance from the other end of the front main body part 200 in the first direction X to the front-penetrating part A10. Therefore, when the one glue tab 210 is placed over the front main body part 200, the front-penetrating part A10 is prevented from being blocked by the one glue tab 210, and when the back main body part 211 is placed over the one glue tab 210, the front-penetrating part A10 and the back-penetrating part A12 can be connected to each other.

Furthermore, according to the hanging bag 1 of the first embodiment, the back penetration portion A12 is configured as a hole with a larger diameter than the front penetration portion 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-side glue margin portion 210 are overlapped, the penetration portion (back penetration portion A12) of the member located in the center in the third direction Z has a larger diameter than the other penetration portions (front penetration portion A10, one-side through portion 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-side glue margin portion 210 are overlapped, the front penetration portion A10, the back penetration portion A12, and the one-side through portion A11 can communicate with each other. Therefore, for example, when forming the front penetration portion A10, the back penetration portion A12, and the one-side through portion A11 by machine, processing errors can be prevented.

In addition, in the hanging bag 1 of the first embodiment, the rear 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 rear penetration portion A12 with a larger diameter than the front penetration portion A10 and the one-end penetration portion A11, so the appearance is less likely to be unnatural.

In addition, 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 surface 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 separate shape-retaining backing sheet for the items inside the bag main body 2. Additionally, 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 is ensured, preventing the bag from tearing and exposing the stored items, for example.

In this embodiment, the one-end extension portion 212 is longer in the second direction Y than the other-end extension portion 213, ensuring a sufficient adhesive area with the rear main body portion 211 for the one-end through portion A11.

In addition, in this embodiment, when the one glue tab portion 210 and the back main body portion 211 overlap, a recess 2a is formed at the other end of the bag main body 2 in the second direction Y (the lower end in Figure 1). Therefore, when storing items in the bag main body 2, the items can be stored without getting caught at the other end in the second direction Y.

Next, the hanging bag 1 of the second embodiment will be described using Figures 3 and 4. When describing the hanging bag 1 of the second embodiment, the same configuration as the first embodiment will not be described.

As shown in Figure 3, in the hanging bag 1 of the second embodiment, one end 24 (the upper end in Figure 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.

The hanging bag 1 of the second embodiment does not have a portion equivalent to the one-side sealing portion 240 of the first embodiment. However, as shown in Figure 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-side sealing portion 250 described in the first embodiment.

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. In the second embodiment, the front main body portion 200 is formed in a rectangular shape with the first direction X being longer than the second direction Y.

The front main body portion 200 has a first through portion A100 and a second through portion A101 formed 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 placed 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 positioned in the center in the first direction X. Furthermore, in this embodiment, the first through portion A100 is positioned in the first direction X between the front and back adhesive portions 32, 32 described below.

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. In this embodiment, the second through portion A101 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. In addition, the second through portion A101 in this embodiment is positioned in the first direction X between the front and back adhesive portions 32, 32 described below. In this embodiment, the second through portion A101 is positioned near the other end in the second direction Y.

The back surface portion 21 of the second embodiment comprises 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.

The rear body portion 211 is provided continuous from the other end of the front body portion 200 in the second direction Y (the lower end in Figure 4). In the second embodiment, the one glue margin portion 210 and the other glue margin portion 214 are overlapped on the front body portion 200, and the rear 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 body portion 211 in the second embodiment is set so that it overlaps the one glue margin portion 210 and the other glue margin portion 214. On the other hand, the length of the rear body portion 211 in the second embodiment is set so that it overlaps the one end extension portion 212. The rear body portion 211 in the second embodiment is shorter in the second direction Y than the front body portion 200. Therefore, as shown in FIG. 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 FIG. 3) in the second direction Y than the rear main body portion 211.

A back-penetrating portion A12 is formed in the rear main body portion 211. This back-penetrating portion A12 is formed in a portion of the rear main body portion 211 that overlaps with the first front-penetrating 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-penetrating portion A12 and the first front-penetrating portion A100 are connected. In this embodiment, the back-penetrating portion A12 is configured as a circular hole with a larger diameter than the first front-penetrating portion A100 and the first-penetrating portion A11.

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 Figure 4) of the rear penetration portion A12.

In addition, the other end of the tear assisting portion 6 in the first direction X (the left end in Figure 4) in the second embodiment is configured as a tear initiation portion 51 that triggers opening. That is, the tear initiation portion 51 in this embodiment is formed at the intersection of the first direction X and the second direction Y of the tear assisting portion 6, and is inclined with respect to the first direction X and the second direction Y. By pulling this tear initiation portion 51, the rear main body portion 211 is broken in the first direction X and the second direction Y along the tear assisting portion 6.

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

The adhesive portion 3 is used to bond the front main body portion 200, the rear main body portion 211, and the one-end extension portion 212. As shown in Figure 4, the adhesive portion 3 in this embodiment includes a front-back adhesive portion 32 that bonds the front main body portion 200 and the rear main body portion 211 together, a sealing adhesive portion 30 that bonds the rear main body portion 211 and the one-end extension portion 212 together, and an auxiliary adhesive portion 31 that bonds the front main body portion 200 and the one-end extension portion 212 together.

The front and back adhesive portions 32 are intended to bond the front main body portion 200 and the back main body portion 211, which are stacked in the third direction Z. As shown in FIG. 3, the front and back adhesive portions 32 of this embodiment bond the front main body portion 200 and the back main body portion 211 to one end side and the other end side in the first direction X, relative to the front-penetrating portion. Furthermore, the front and back adhesive portions 32 are positioned closer to the front-penetrating portion in the first direction X, relative to the one glue margin portion 210 and the other glue margin portion 214, which are stacked on the front main body portion 200. Furthermore, as shown in FIG. 4, the front and back adhesive portions 32 of this embodiment are positioned in the second direction Y across the front main body portion 200 and the back main body portion 211.

The sealing adhesive portion 30 comprises a backside 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 backside 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 positioned so as to overlap the backside adhesive portion 301 when the one end extending portion 212 is overlapped on the back main body portion 211. Furthermore, in this embodiment, the extended adhesive portion 300 is formed on the one end side in the second direction Y relative to the one end penetration portion A11. In this embodiment, the backside adhesive portion 301 and the extended adhesive portion 300 are formed to have approximately the same length in the first direction X. Note that the sealing adhesive portion 30 in this embodiment is configured as adhesive glue.

The auxiliary adhesive portion 31 is intended to adhere the front main body portion 200 and the one-end extension portion 212 when the front main body portion 200 and the one-end extension portion 212 are overlapped. As shown in FIG. 4 , the auxiliary adhesive portion 31 in this embodiment comprises 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 extension 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 extension 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 disposed 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. Note that the auxiliary adhesive portion 31 of this embodiment is made of adhesive glue.

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 composed of an auxiliary adhesive portion 31. That is, the auxiliary adhesive portion 31 bonds the front main body portion 200 to the one-end extension portion 212 at one end side in the second direction Y relative to the through hole A1 (the upper end side in Figure 3), thereby preventing the bag body 2 from expanding in the third direction Z. Therefore, the hanging reinforcement portion of this embodiment bonds the front main body portion 200 to the one-end extension portion 212, preventing the bag body 2 from expanding in the third direction Z at one end side in the second direction Y relative to the through hole A1. 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 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.

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

The other sealing portion 250 in 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 sealing 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 adhesive portion 301, the rear main body portion 211 and the one-end extending portion 212 are bonded to form the other sealing portion 250.

As shown in FIG. 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 connecting the first front through portion A100, the one-side through portion A11, and the rear through portion A12.

When forming the hanging bag 1 of the second embodiment using the above configuration, the first fold a is folded to overlap the first glue margin 210 and the second glue margin 214 on the front main body portion 200, and then the second fold b is folded to overlap the rear main body portion 211 on the front main body portion 200, the first glue margin 210, and the second glue margin 214. This connects the first front penetration portion A100 and the rear penetration portion A12 in the third direction Z. Furthermore, when the rear main body portion 211 is overlapped on the front main body portion 200, the first glue margin 210, and the second glue margin 214, the rear main body portion 211 is adhered to the first glue margin 210 and the second glue margin 214, and the rear 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.

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

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 passes through 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, allowing the hanging bag 1 to be hung securely.

In addition, in the second embodiment, the one-end extension 212 and the front main body 200 are bonded together by the auxiliary adhesive 31 on the one end side in the second direction Y of the through hole A1, thereby forming a hanging reinforcement portion. Therefore, the auxiliary adhesive 31 prevents the front main body 200 and the one-end extension 212 from separating on the one end side in the second direction Y of the through hole A1, and the hanging reinforcement portion prevents the one end side in the second direction Y of the through hole A1 from being torn due to the weight of the hanging bag 1, etc.

In addition, in this embodiment, the front main body portion 200 and the rear main body portion 211 are bonded together by the front and rear adhesive portions 32, 32. Therefore, when items are 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. Between the front and rear adhesive portions 32, 32, the bag main body 2 is given a bulge in the third direction Z, creating a three-dimensional effect.

In addition, in the second embodiment, a window portion 4 is provided in the front main body portion 200. Therefore, items inside the bag main body 2 can be checked through the window portion 4. In particular, in this embodiment, when the hanging bag 1 is hung, the items inside the hanging bag 1 can be checked from the front main body portion 200 on the front side. Furthermore, because the second through-hole A101 that constitutes the window portion 4 is positioned near the other end in the second direction Y (the lower end in Figure 3), it is easy to check 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.

Next, we will explain the hanging bag 1 according to the third embodiment. When explaining the hanging bag 1 according to the third embodiment, we will omit explanations that are the same as those for the hanging bag 1 according to the first and second embodiments.

As shown in Figure 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 items are placed inside 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 assist portion c (shown in Figure 8), an adhesive portion 3, a window portion 4, and a hanging portion A.

The bag body 2 includes a front portion 20 and a back portion 21 that are arranged opposite each other in the third direction Z. As shown in FIG. 8 , the front 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 has 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 numbered). 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. This 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 this embodiment is configured as a circular hole with a larger diameter than the first through-hole A100. This 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. In this embodiment, the second through portion A101 is formed on the other end in the first direction X (the right end in FIG. 8 ). In this embodiment, the second through portion A101 is configured as a window 4 for checking the inside of the bag body 2.

As shown in Figure 8, the back surface portion 21 includes a front one-end extension portion 217 extending from one end of the front main body portion 200 in the second direction Y (top end of Figure 8), a second-end adhesive margin portion 214 extending from the front one-end extension portion 217 to one end of the front main body portion 200 in the first direction X (right end of Figure 8), a back plate portion 21a extending from the other end of the front main body portion 200 in the first direction X (left end of Figure 8), and a second-end extension portion 213 extending from the other end of the front main body portion 200 in the second direction Y (bottom end of Figure 8).

The front end extension 217 is located at one end of the front main body 200 in the second direction Y (the upper end in Figure 8). This front end extension 217 is connected in the first direction X to the extended glue margin 215 and the back end extension 212, which will be described later, across a separation assisting portion c, which will be described later. The front end extension 217 is provided with a front end through-portion A13a that penetrates the front end extension 217 in the third direction Z. This front end through-portion A13a is located so as to communicate with the back end through-portion A13b when the front end extension 217 and the back end extension 212 are overlapped.

As shown in Figure 8, in the third embodiment, the other glue margin 214 includes an extended glue margin 215 that overlaps the front end extension 217, and a main body glue margin 216 that overlaps the front main body 200. That is, in the third embodiment, when the first fold a is folded, the extended glue margin 215 overlaps the front end extension 217, and the main body glue margin 216 overlaps the front main body 200.

As shown in FIG. 8 , the back plate portion 21a includes a back 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 body portion 211. The back body portion 211 is formed to have approximately the same length as the front body portion 200 in the first direction X and the second direction Y. Therefore, when folded along the first fold a, the back body portion 211 closely overlaps the front body portion 200. In addition, the back body portion 211 of this embodiment is formed with a back penetration portion A12 that penetrates the back body portion 211 in the third direction Z. This back penetration portion A12 is positioned so as 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 in the second direction Y (the lower end side in FIG. 8 ) than the first front penetration portion A100.

The rear end extension 212 is provided from one end of the rear main body 211 in the second direction Y (the upper end in FIG. 8 ). In this embodiment, the rear end extension 212 is formed to be approximately the same as the rear main body 211 in the first direction X. Therefore, when the rear end extension 212 is folded along the second fold b and placed on the rear main body 211, the rear end extension 212 closely overlaps the rear main body 211. The rear end extension 212 has a rear one-side through-hole A13b that penetrates in the third direction Z. As shown in FIG. 5 , this rear one-side through-hole A13b is positioned so as to communicate with the front one-side through-hole A13a when the rear end extension 212 is placed on the front one-side through-hole 217 (not shown in FIG. 5 ). Furthermore, in this embodiment, the rear one-side through-hole A13b is configured as a circular hole that is longer in the first direction X than the front one-side through-hole A13a.

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

The other sealing portion 250 in the third embodiment is composed of a front end extension portion 217, a rear end extension 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 extension portion 217 (not shown in FIG. 5), the extended glue margin portion 215 overlapping the front end extension portion 217, and the rear end extension portion 212 with the rear main body portion 211, thereby sealing one end portion 24 of the bag main body 2 in the second direction Y, as shown in FIG. 6.

As shown in Figure 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 Figure 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.

The separation assisting portion c is configured to separate the extension portion in the third direction Z. This separation assisting portion c is configured as a dashed-line perforation that extends intermittently in the second direction Y between the front end extension portion 217 and the back end extension portion 212 and extended glue margin portion 215. Furthermore, in this embodiment, the separation assisting portion c is continuous from the first fold a in the second direction Y. Therefore, by folding the first fold a and overlapping the front end extension portion 217, extended glue margin portion 215, and back end extension portion 212, the front end extension portion 217 and back 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 and left ends in Figure 5). Note that the separation assisting portion c in this embodiment is configured to extend along the second direction Y.

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

In this embodiment, the bag body 2 is folded from the state shown in FIG. 8 along the first fold a, with the other glue tab 214 overlapping the back side of the front body portion 200, and the back plate portion 21a overlapping and bonded to the back side of the other glue tab 214. Then, the second fold b is folded, and the other front end extension 213 is overlapping and bonded to the back 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 body portion 200 and the back 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.

After placing an item inside the bag body 2 from the opening at one end 24 in the second direction Y, the second fold b is folded and the rear end extension 212 is placed on top of the rear main body 211. At this time, as shown in Figures 6 and 7, the adhesive portion 3 is adhered to the rear main body 211 and also adhered to the front main body 200 via the rear penetration portion A12. Therefore, the other sealing portion 250 seals the one end 24 of the bag body 2 in the second direction Y. Furthermore, by placing the rear end extension 212 on top of the rear main body 211, the front one penetration portion A13a, the rear one penetration portion A13b, the first front penetration portion A100, and the rear penetration portion A12 are connected.

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 rear end extension portion 212 overlap the front main body portion 200 and the rear main body portion 211, allowing the other sealing portion 250 to seal one end portion 24 of the bag main body 2 in the second direction Y.

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 portions c, c are broken, and the back end extension portion 212 and the front end extension portion 217 are separated in the third direction Z, causing the front end extension portion 217 to stand upright on one end side in the second direction Y, as shown in Figure 7. Therefore, in the hanging bag 1 of this embodiment, once the separation assisting portions c, c are broken to open one end 24 in the second direction Y, it can be seen that one end 24 of the bag main body 2 in the second direction Y has been opened due to the breaking of the separation assisting portions c, c.

In addition, in the third embodiment, the separation assisting portions c, c are arranged in the second direction Y, making it easier to open one end 24 of the bag body 2 in the second direction Y.

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 the hanging bag 1 can be supported by the front one-end extension 217, the back one-end extension 212, the back main body 211, and the front main body 200.

In addition, 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 penetration portion A12. Therefore, as shown in FIG. 7, the front portion 20 (not shown in FIG. 7) and the back portion 21 are adhered (joined) in the third direction Z at the other end side (lower end side) of the through hole A1 in the second direction Y. This prevents items in the bag main body 2 from rising in the second direction Y so as to overlap the through hole A1.

In addition, in the third embodiment, the second through portion A101 that constitutes the window portion 4 is located closer to the other end in the second direction Y (the lower end in Figure 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 in the first direction X (the right end in Figure 8). Therefore, in this embodiment, because 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.

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 items in the bag body 2 are prevented from rising in the second direction Y, thereby preventing the through hole A1 from overlapping with the items. However, in the first and second embodiments, a similar method to that of the third embodiment may be used to prevent the through hole A1 from overlapping with the items. In this case, it is considered that the through hole of the member located in the middle in the third direction Z is configured to be larger toward the lower end than the other through holes. Alternatively, items in the bag body 2 may be prevented from rising in the second direction Y using a method other than the above, such as 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.

In the first embodiment described above, a case was described in which one end 24 in the second direction Y is closed and the other end 25 is open. However, 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.

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 body portion 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 the length of one of the adhesive margins 210 in the first direction X may be set, for example, so as to block only at least a portion of the front-penetrating portion A10.

In addition, 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. However, this 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 extension 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 extension 213.

In addition, in the above first to third embodiments, the through hole A1 serving as the hanging portion A is described as being circular, but this is not limiting 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 composed 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 easy 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.

Furthermore, in the first to third embodiments described above, the diameters of the through-holes A1 are different for each of the through-holes, but this is not limiting, and for example, all of the through-holes may have the same diameter.

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. For example, instead of the through hole A1, a hook may be attached as the hanging portion A.

In addition, in the first to third embodiments described above, the one end 24 or the other end 25 in the second direction Y is sealed by the one end extension 212 or the other end extension 213 overlapping the front main body portion 200 or the rear main body portion 211. However, this is not limited to this. 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 rear portion 21 together within the bag body 2. In other words, in this case, the other sealing portion 250 is configured as an adhesive portion that bonds the front portion 20 and the rear portion 21 together.

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

In addition, in the third embodiment, the separation assisting portion c is disposed at both ends in the first direction X, but this is not a limitation. For example, it may be formed between both ends in the first direction X. That is, in this case, it is conceivable that the separation assisting portion c is not continuous with the first fold a in the second direction Y. In addition, while the separation assisting portion c in the third embodiment is configured to extend along the second direction Y, this is not a limitation. For example, it may be inclined toward the first direction X as it progresses in the second direction Y.

In addition, in the third embodiment described above, the separation assisting portion c is configured as a broken-line perforation extending intermittently in the second direction. However, this is not limited to this. For example, the separation assisting portion c may be configured as an adhesive portion provided on the front end extension portion 217 for releasably adhering the front end extension portion 217 and the back end extension portion 212.

In the second embodiment described above, the hanging reinforcement portion is formed by bonding the front main body portion 200 and the one-end extension 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 ). However, this is not limited to this. For example, the front main body portion 200 or the one-end extension 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 extension portion 212 closer to each other, thereby increasing strength. Furthermore, when forming the hanging reinforcement portion, it is not necessary for the front main body portion 200 and the one-end extension portion 212 to be bonded with the auxiliary adhesive portion 31; for example, the front main body portion 200 and the one-end extension portion 212 may be bonded (joined) without the auxiliary adhesive portion 31.

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

In addition, in the second embodiment described above, the adhesive portion 3 includes a front-back adhesive portion 32 to bond the front main body portion 200 and the rear main body portion 211 in the third direction Z. However, this is not limiting. For example, the adhesive portion 3 may not include a front-back adhesive portion 32 in order to not bond the front main body portion 200 and the rear main body portion 211 in the third direction Z.
