[0009] Hereinafter, an embodiment of the packaging material will be described with reference to the drawings. First, a first embodiment will be described.

[0010] Fig. 1 is a schematic perspective view showing a packaging material according to a first embodiment, and Fig. 2 is an exploded perspective view of the packaging material shown in Fig. 1. Also, Fig. 3 is a schematic view showing the internal structure of the packaging material shown in Fig. 1.

[0011] The packaging material 1 of this embodiment is a bag-shaped member that stores items having a relatively flat shape, such as can badges, as storage objects A1. In a barter service via the Internet, this packaging material 1 is sent for packaging by a platform company that mediates the service to each provider of the items desired to be exchanged. A logo mark or the like indicating the platform company is printed on the outermost surface of the packaging material 1, and its quality is guaranteed. Each provider who receives the packaging material 1 stores and packs an item in the packaging material 1, and sends it to the exchange partner by mail or the like. This packaging material 1 includes two storage bags 11 and a cushioning material 12.

[0012] The two storage bags 11 are two bags, one large and one small, which are different in size from each other, and form a nested structure in which the smaller bag is relatively contained in the larger bag. The smaller bag 11 located on the innermost side is called the innermost bag 111, and the larger bag 11 located on the outermost side is called the outermost bag 112. In this embodiment, the storage bag 11 is composed of two bags, one large and one small, so one is the innermost bag 111 and the other is the outermost bag 112. The innermost bag 111 and the outermost bag 112 each have a storage opening 111a, 112a, and form a nested structure in which the innermost bag 111 is contained in the outermost bag 112 with the storage openings 111a, 112a oriented in the same direction. In this embodiment, both of the two storage bags 11 are formed of a transparent resin sheet such as OPP (Oriented Polypropylene) or the like.

[0013] A flap 112c is provided at the opening 112a of the outermost bag 112 so as to be able to be sealed, with a fold line 112b forming part of the opening edge. A strip of adhesive glue 112d for sealing is applied to the flap 112c across the entire width of the outermost bag 112, and the adhesive glue 112d is masked with masking tape 112e to prevent it from sticking unintentionally. An object A1 to be contained is contained in the innermost bag 111 of the two containing bags 11 through the opening 111a of the innermost bag 111.

[0014] The cushioning material 12 is a member provided to protect the innermost bag 111 of the two storage bags 11, and absorbs external forces. The cushioning material 12 covers the outer surface of the innermost bag 111, which is the bag to be protected, and is adhered and fixed to a bonding area 111b on a portion of the outer surface in a state in which the storage opening 111a can be opened and closed. In this embodiment, the bonding area 111b of the cushioning material 12 on the outer surface of the innermost bag 111 is only a portion close to the storage opening 111a. One bonding area 111b is provided on each of the outer surfaces of the front and back of the innermost bag 111 when it is folded into a sheet shape.

[0015] Moreover, at least a part of the adhesive area 12a on the outer surface of the cushioning material 12 is adhesively fixed to the inner surface of an outer bag (in this embodiment, the outermost bag 112) located outside the cushioning material 12. This adhesive fixation is performed in a state in which the opening 111a of the innermost bag 111, which is the bag to be protected located inside the cushioning material 12, can be opened and closed by opening and closing the opening 112a of the outermost bag 112. Moreover, the adhesive area 12a on the outer surface of the cushioning material 12 is only a part near the opening 111a of the innermost bag 111. And, the adhesive area 12a of the cushioning material 12 is provided on each of the outer surfaces of the front and back of the cushioning material 12 when the cushioning material 12 is folded into a sheet.

[0016] Here, in this embodiment, the cushioning material 12 is provided in a bag shape that covers the entire outer surface including the bottom 111c of the innermost bag 111, which is the bag to be protected, and the orientation of the accommodation opening 12b is aligned with the accommodation openings 111a, 112a of the innermost bag 111 and the outermost bag 112. Furthermore, the cushioning material 12 is a double bag of an inner cushioning bag 121 and an outer cushioning bag 122 so as to surround and cover the outer surface of the innermost bag 111 at least twice. The inner cushioning bag 121 is a bag smaller in size than the outer cushioning bag 122, and the cushioning material 12 has a nested structure in which the inner cushioning bag 121 is accommodated in the outer cushioning bag 122 with the orientations of the inner accommodation opening 12b-1 and the outer accommodation opening 12b-2 aligned. In addition, the outer surface of the inner cushioning bag 121 and the inner surface of the outer cushioning bag 122 are bonded and fixed over a wide area so as not to be separated from each other. The inner storage opening 12b-1 and the outer storage opening 12b-2, which are integrated with each other by this adhesive fixation, form the storage opening 12b of the cushioning material 12, and the innermost bag 111 is stored through this storage opening 12b. The adhesive area 111b of the innermost bag 111 is adhesively fixed to the inner surface of the inner cushioning bag 121, and the adhesive area 12a provided on the outer surface of the outermost bag 122 is adhesively fixed to the inner surface of the outermost bag 112. Each of the inner cushioning bag 121 and the outer cushioning bag 122 is formed into a bag shape using air bubble cushioning material.

[0017] The object A1 is packaged with the packaging material 1 of this embodiment as follows. First, the opening 112a of the outermost bag 112 is opened, and the opening 12b of the cushioning material 12 inside and the opening 111a of the innermost bag 111 are opened together. The object A1 is packaged inside the innermost bag 111 through the opening 111a of the opened innermost bag 111. Next, the masking tape 112e is peeled off from the sealing flap 112c provided at the opening 112a of the outermost bag 112 to expose the strip-shaped adhesive glue 112d. After that, the flap 112c is folded at the crease line 112b, and the flap 112c is adhesively fixed to the outer surface of the outermost bag 112 by the adhesive glue 112d, thereby sealing the object A1 and completing the packaging of the object A1. The above operations are carried out by each provider of goods who has received the packaging material 1 from the platform operator who mediates the barter service. When the provider has completed packing the provided goods as the storage objects A1 in the packaging material 1, the provider will ship the packed provided goods to the exchange partner.

[0018] In the above description, an object A1 having a relatively flat shape, such as a can badge, is given as an example of an object to be stored in the packaging material 1 of this embodiment. However, the object to be stored in the packaging material 1 is not limited to this, and may be a small three-dimensional structure such as a capsule toy, as long as it has a size and shape that can be stored.

[0019] According to the packaging material 1 of the first embodiment described above, the object A1 is contained in the innermost bag 111 in the nested structure, and the cushioning material 12, which protects the innermost bag 111, covers the outer surface. Therefore, the object A1 contained in this packaging material 1 is stably protected by the cushioning material 12 from external forces during transportation. And, since the cushioning material 12 is bonded and fixed to a part of the outer surface of the innermost bag 111 in a state in which the storage opening 111a can be opened and closed, the storage opening 111a of the innermost bag 111 can be opened together with the cushioning material 12 to store the object A1, reducing the effort required for storage. Thus, according to the packaging material 1 described above, it is possible to perform stable packaging while reducing the effort required for the person performing the packing.

[0020] In this embodiment, the cushioning material 12 is adhered and fixed only to a part of the outer surface of the innermost bag 111, which is the bag to be protected, near the storage opening 111a. This configuration allows the innermost bag 111 to move appropriately when storing the storage object A1, thereby increasing the degree of freedom regarding storage.

[0021] In this embodiment, a part of the outer surface of the cushioning material 12 is adhered and fixed to the inner surface of an outermost bag 112, which is an outer bag located outside the cushioning material 12, in a state in which the storage opening 111a of the innermost bag 111 can be opened and closed by opening and closing the storage opening 112a of the outermost bag 112. With this configuration, the storage opening 111a of the innermost bag 111 can be opened together with the outermost bag 112 via the cushioning material 12 to store the storage object A1, further reducing the effort required for storage.

[0022] In this embodiment, only a portion of the outer surface of the cushioning material 12 that is close to the storage opening 111a of the innermost bag 111 is adhered and fixed to the inner surface of the outermost bag 112. This configuration allows the cushioning material 12 to move appropriately together with the innermost bag 111 inside the outermost bag 112 when storing the storage object A1, thereby increasing the degree of freedom regarding storage.

[0023] Furthermore, in this embodiment, the cushioning material 12 is provided so as to cover the entire outer surface including the bottom 111c of the innermost bag 111. This configuration can prevent the position of the cushioning material 12 from shifting in the depth direction of the innermost bag 111. Furthermore, compared to a case where cushioning material is provided individually for each surface of the innermost bag 111 and the edges are taped together, the cushioning material 12 covers the bottom 111c of the innermost bag 111 from the beginning, which can reduce the effort required for taping and the like.

[0024] In this embodiment, the cushioning material 12 doubly surrounds and covers the outer surface of the innermost bag 111. With this configuration, the cushioning material 12 is provided so as to surround the innermost bag 111 doubly, thereby making it possible to enhance the effect of absorbing external forces.

[0025] In this embodiment, the storage opening 112a of the outermost bag 112 of the two storage bags 11 is provided with a flap 112c with a fold line 112b as a part of the opening edge so as to be able to be sealed. This configuration can reduce the labor required for sealing for waterproofing after the storage object A1 is stored. In addition, since the flap 112c for sealing is provided with a fold line 112b as a part of the opening edge of the storage opening 112a of the outermost bag 112, the flap 112c is bent at a fixed position to perform sealing. This allows even an inexperienced person to perform highly waterproof sealing.

[0026] In this embodiment, both of the two storage bags 11 are formed from a transparent resin sheet. This configuration is preferable because it allows the recipient of the packaged item to see the inside of the package through the packaging material, providing a sense of security.

[0027] In this embodiment, a logo mark or the like indicating the platform operator is printed on the outer surface of the outermost bag 112, which is the outermost surface of the packaging material 1, to guarantee its quality. This configuration makes the origin of the packaging material 1 clear, which also gives a sense of security to the recipient of the item.

[0028] In this embodiment, the cushioning material 12 is made of a bubble cushioning material. With this configuration, the cost of the cushioning material 12 can be reduced by using a bubble cushioning material that is easily available.

[0029] Next, a second embodiment will be described. This second embodiment differs from the first embodiment in the shape of the article to be stored and the shape of the innermost bag in which the article is stored. Below, the second embodiment will be described focusing on the differences from the first embodiment.

[0030] Fig. 4 is a schematic diagram showing the internal structure of a packaging material according to a second embodiment, similar to Fig. 3. In Fig. 4, components equivalent to those of the first embodiment shown in Fig. 3 are given the same reference numerals as in Fig. 3 only for those components necessary for explanation, and hereinafter, redundant explanations of the equivalent components will be omitted.

[0031] The packaging material 2 of this embodiment is a bag-shaped member that contains a small three-dimensional structure such as a capsule toy as a storage object A2. This packaging material 2 includes a slightly large outermost bag 112 and a cushioning material 12 formed in a double bag shape with air bubble cushioning material, similar to the above-mentioned first embodiment. On the other hand, in this embodiment, the innermost bag 211 that constitutes two storage bags 21 together with the outermost bag 112 is a bag large enough to contain a small three-dimensional structure, and its storage opening 211a is also provided with a sealable flap 211c. The flap 211c of this innermost bag 211 is provided with a fold line 211b on a part of the opening edge of the storage opening 211a, similar to the flap 112c of the outermost bag 112.

[0032] In the packaging material 2 of this embodiment, the storage object A2, which is a small three-dimensional structure, is stored in the slightly larger innermost bag 211, and then sealed by the flap 211c of the innermost bag 211. The sealing here is performed in the same manner as the flap 112c of the outermost bag 112, by peeling the masking tape 212e from the flap 212c of the innermost bag 211 to expose the strip-shaped adhesive glue 212d, and folding the flap 212c at the crease line 212b. This folding causes the flap 212c to be adhesively fixed to the outer surface of the innermost bag 212 with the adhesive glue 212d, thereby sealing the object. Thereafter, the flap 112c of the outermost bag 112 is sealed to double seal the object, and the packaging of the storage object A2, which is a small three-dimensional structure, with the packaging material 2 is completed.

[0033] In the above description, the object A2 is a small three-dimensional structure such as a capsule toy, as an example of the object to be stored in the packaging material 2 of this embodiment. However, the object to be stored in the packaging material 2 is not limited to this, and may be an item having a relatively flat shape, such as a can badge, as long as it has a size and shape that can be stored.

[0034] It goes without saying that the packaging material 2 of the second embodiment described above can also perform packaging with a stable level while reducing the burden on the person doing the packaging, similar to the first embodiment described above.

[0035] In this embodiment, the innermost bag 211 in which the storage object A2 is stored is also provided with a sealable flap 211c. This double sealing configuration allows for highly waterproof sealing of the storage object A2, which is a small three-dimensional structure that is more likely to have gaps in the seal compared to the flat storage object A1.

[0036] Next, a third embodiment will be described. The third embodiment differs from the first embodiment in the shape of the stored item and the configuration of the cushioning material. The following describes the third embodiment, focusing on the differences from the first embodiment.

[0037] Fig. 5 is a schematic perspective view showing a packaging material according to a third embodiment, and Fig. 6 is an exploded perspective view of the packaging material shown in Fig. 5. Also, Fig. 7 is an exploded perspective view of the cushioning material shown in Fig. 6.

[0038] The packaging material 3 of this embodiment is a bag-like member that contains an object A3, such as a card-like thin article that is easily deformed. The packaging material 3 includes a double-layered storage bag 11 that is composed of an innermost bag 111 and an outermost bag 112, similar to the first embodiment described above. On the other hand, the cushioning material 32 in this embodiment, which uses the innermost bag 111 as the bag to be protected, is not bag-like, unlike the first embodiment, and has a configuration that holds the innermost bag 111 by sandwiching it, and includes two rectangular flat plates 321 and a cushion portion 322.

[0039] The two rectangular flat plates 321 hold the innermost bag 111 between them, and in this embodiment, they are a pair of plate-like parts constituting a folded cardboard box 323 in which a rectangular piece of cardboard is folded in half along a crease line 321a in the center in the longitudinal direction. The innermost bag 111 is bonded and fixed at an adhesive area 1111b on its outer surface near the storage opening 111a to the opposing inner surfaces of the two rectangular flat plates 321 of the folded cardboard box 323 in a state in which the storage opening 111a can be opened and closed.

[0040] The cushion portion 322 is a rectangular sheet-like object attached to the outer surfaces of the two rectangular flat plates 321, and in this embodiment, has a double structure in which two rectangular bubble cushioning materials are stacked. This double-structured cushioning portion 322 is folded in half at a location corresponding to the crease line 321a of the folding cardboard 323, and is attached entirely to the outer surfaces of each rectangular flat plate 321 to form the cushioning material 32 folded in half. In addition, on the outer surface of the cushioning portion 322 of this cushioning material 32, an adhesive area 32a for bonding with the outermost bag 112 is provided near the storage opening 111a of the innermost bag 111 on the inside. This adhesive area 32a is provided on each of the outer surfaces of the front and back of the cushioning material 32 folded in half, and is adhesively fixed to the inner surface of the outermost bag 112.

[0041] In the packaging material 3 of this embodiment, a thin, easily deformed object such as a card is packaged as the object A3. When packaging, the opening 112a of the outermost bag 112 is opened, and the opening 111a of the innermost bag 111 is opened through the cushioning material 32 folded in half, and the object A3 is packaged in the innermost bag 111 through the opening 111a. Next, the masking tape 112e is peeled off from the sealing flap 112c provided at the opening 112a of the outermost bag 112 to expose the strip-shaped adhesive glue 112d. After that, the flap 112c is folded at the crease line 112b, and the flap 112c is adhesively fixed to the outer surface of the outermost bag 112 by the adhesive glue 112d, thereby sealing the object A3 and completing the packaging of the object A3.

[0042] It goes without saying that the packaging material 3 of the third embodiment described above can also perform packaging with a stable level while reducing the burden on the person doing the packaging, similar to the first embodiment described above.

[0043] In this embodiment, the cushioning material 32 includes two rectangular flat plates 321 that sandwich and hold the innermost bag 111 as the bag to be protected between them, and cushion portions 322 attached to the outer surfaces of the two rectangular flat plates 321. With this configuration, a thin and easily deformed article such as a card-shaped item as the storage object A3 can be effectively protected by sandwiching it between the two rectangular flat plates 321, and the cushion portions 322 on the outer surfaces can suppress the effects of external forces.

[0044] Next, a fourth embodiment will be described. The fourth embodiment differs from the first embodiment in that the stored items are relatively large items such as stuffed toys, and the fourth embodiment is configured to be able to store such items. Below, the fourth embodiment will be described focusing on the differences from the first embodiment.

[0045] FIG. 8 is a schematic exploded perspective view of a packaging material according to a fourth embodiment.

[0046] The packaging material 4 of this embodiment is a bag-shaped member that stores a relatively large item such as a stuffed toy as a storage object A4, as described above. The basic structure of this packaging material 4 is the same as that of the first embodiment described above, and includes two storage bags 41 consisting of an innermost bag 411 and an outermost bag 412 formed of a transparent resin sheet, and a cushioning material 42 formed in a double bag shape with air bubble cushioning material. The two storage bags 41 and the cushioning material 42 are such that the innermost bag 411, which is the smallest size, is large enough to store a storage object A4 such as a stuffed toy, and the cushioning material 42 and the outermost bag 412 are large enough to accommodate the innermost bag 411 on the inside. Furthermore, the innermost bag 411, the cushioning material 42, and the outermost bag 412 are all rectangular bags with foldable gussets 411a, 42a, and 412a formed on the sides. An adhesive area 411c is provided near the storage opening 411b of the innermost bag 411 and is adhesively fixed to the inner surface of the cushioning material 42. Similarly, an adhesive area 42c is provided near the storage opening 42b of the cushioning material 42 and is adhesively fixed to the inner surface of the outermost bag 412.

[0047] In addition, a flap 412c is provided at the storage opening 412b of the outermost bag 412. This flap 412c is formed with a sufficient length to be able to seal the bag even when the A4 storage object is stored and the gusset 412a is open, and is coated with adhesive glue 412d and masked with masking tape 412e.

[0048] It goes without saying that the packaging material 4 of the fourth embodiment described above can also perform packaging with a stable level while reducing the effort required by the person doing the packaging, similar to the first embodiment described above.

[0049] In this embodiment, the two storage bags 41 and the cushioning material 42 are both rectangular bags with foldable gussets 411a, 42a, 412a on the sides. This configuration allows for effective storage of relatively large storage objects A4, such as stuffed toys. The packaging material 4 of this embodiment may also be used to store flat objects such as the can badges in the first embodiment, or small three-dimensional objects such as capsule toys.

[0050] The above-described first to fourth embodiments are merely examples of the packaging material, and the packaging material is not limited to these embodiments. In other words, the packaging material can be used by making appropriate modifications according to the respective applications.

[0051] For example, in the above-mentioned first to fourth embodiments, packaging materials 1, 2, 3, and 4 are exemplified as an example of a packaging material, which includes two storage bags 11, 21, and 41, namely, an innermost bag 111, 211, and an outermost bag 112, and the innermost bag 111, 211, and 411 are covered with a cushioning material 12, 32, and 42. However, the packaging material is not limited to this, and may include three or more storage bags. In this case, the cushioning material may be provided for only the innermost bag among the storage bags excluding the outermost bag as the bag to be protected, or the cushioning material may be provided for each bag, with the innermost bag and all or part of the other bags being the bags to be protected.

[0052] In the above-mentioned first to fourth embodiments, the cushioning material 12, 32, 42 is adhesively fixed only to a part of the outer surface of the bag to be protected that is close to the storage opening 111a, 211a, 411b. However, the cushioning material is not limited to this, and may be adhesively fixed to the entire outer surface of the bag to be protected, and even if it is adhesively fixed only to a part of the outer surface, it may be adhesively fixed at a position away from the storage opening of the bag to be protected. However, as described above, according to the configuration in which the cushioning material 12, 32, 42 is adhesively fixed only to a part of the outer surface of the bag to be protected that is close to the storage opening 111a, 211a, 411b, the degree of freedom regarding the storage of the storage objects A1, A2, A3, A4 can be increased.

[0053] In the above-mentioned first to fourth embodiments, as an example of the cushioning material, the cushioning material 12, 32, 42 is bonded and fixed to the inner surface of the outer bag (outermost bag 112, 412) located on the outside in a state in which the storage opening 111a, 211a, 411b of the bag to be protected can be opened and closed. However, the cushioning material is not limited to this, and the cushioning material may be stored in the outer bag in a non-adhesive state. However, as described above, by bonding and fixing the cushioning material 12, 32, 42 to the inner surface of the outer bag (outermost bag 112, 412) in a state in which the storage opening 111a, 211a, 411b of the bag to be protected can be opened and closed, the effort required for storage can be further reduced.

[0054] In the above-mentioned first to fourth embodiments, the cushioning material 12, 32, 42 is exemplified as an example of the cushioning material, in which only a part of the outer surface near the storage opening 111a, 211a, 411b of the bag to be protected is adhesively fixed to the inner surface of the outer bag (the outermost bag 112, 412). However, the cushioning material is not limited to this, and the entire outer surface may be adhesively fixed to the inner surface of the outer bag, and even if only a part of the outer surface is adhesively fixed, a position away from the storage opening of the bag to be protected may be adhesively fixed. However, as described above, the configuration in which only a part of the outer surface of the cushioning material 12, 32, 42 near the storage opening 111a, 211a, 411b of the bag to be protected is adhesively fixed to the inner surface of the outer bag (the outermost bag 112, 412) can increase the degree of freedom regarding storage.

[0055] In the first to fourth embodiments described above, the cushioning materials 12, 32, and 42 are provided to cover the entire outer surface of the bag to be protected, including the bottom 111c. However, the cushioning material is not limited to this, and may cover only a part of the outer surface of the bag to be protected. However, by covering the entire outer surface of the bag to be protected, including the bottom 111c, with the cushioning materials 12, 32, and 42, it is possible to suppress the positional deviation of the cushioning materials 12, 32, and 42, and also to reduce the effort of taping the cushioning materials 12, 32, and 42, as described above.

[0056] In the above-mentioned first, second and fourth embodiments, the cushioning material 12, 42 is exemplified as wrapping and covering the outer surface of the bag to be protected in a double layer. However, the cushioning material is not limited to this, and may be, for example, a cushioning material that covers the outer surface of the bag to be protected in only a single layer, as exemplified as the cushioning material 32 in the third embodiment. However, as described above, the cushioning material 12, 42 wrapping and covering the outer surface of the bag to be protected in a double layer can enhance the effect of absorbing external force. The number of cushioning materials is not limited to two, and the outer surface of the bag to be protected may be covered by overlapping multiple layers of three or more layers.

[0057] In the above-mentioned first to fourth embodiments, as an example of the packaging material, the packaging materials 1, 3, and 4 in which the storage openings 112a and 412b of the outermost bags 112 and 412 are provided with the sealable flaps 112c and 412c, and the packaging material 2 in which the storage opening 211a of the innermost bag 211 is also provided with the flap 211c, are shown. However, the packaging material is not limited to this, and may be one in which no sealing flap is provided for any of the multiple storage bags. However, as described above, by providing at least the outermost bags 112 and 412 with the sealing flaps 112c and 412c, the work of sealing for waterproofing and the like can be reduced, and even an inexperienced person can perform highly waterproof sealing.

[0058] In the above-mentioned first to fourth embodiments, as an example of the plurality of storage bags, the plurality of storage bags 11, 21, 41 formed of a transparent resin sheet such as OPP are exemplified. However, the plurality of storage bags are not limited to this, and may be entirely or partially formed of an opaque material. However, as described above, by forming all of the plurality of storage bags from a transparent resin sheet, it is possible to give a sense of security to the recipient of the packaged item.

[0059] In the above-mentioned third embodiment, the cushioning material 32 including two rectangular flat plates 321 and a cushion portion 322 constituting the folded cardboard 323 is exemplified as an example of the cushioning material. However, the cushioning material is not limited to this, and may be formed in a bag shape as exemplified as the cushioning materials 12 and 42 in the first, second, and fourth embodiments. The cushioning material may have any specific configuration as long as it is capable of absorbing an external force on the bag to be protected, covers the outer surface of the bag to be protected, and is bonded and fixed to at least a part of the outer surface in a state in which the storage opening can be opened and closed. However, as described above, the cushioning material 32 including two rectangular flat plates 321 and a cushion portion 322 can effectively protect a thin and easily deformed object such as a card-shaped object as the storage object A3 and suppress the influence of external forces. Note that even if the cushioning material is configured to include two rectangular flat plates and a cushion portion, the two rectangular flat plates are not limited to a part of a folded-shaped member such as the folded cardboard 323. The two rectangular flat plates may be individual flat plates, and may be made of any material other than cardboard, such as a resin plate, a cardboard plate, a wooden plate, a metal plate, etc. In the above-described third embodiment, the cushion portion 322 having a double structure is illustrated as an example of the cushion portion, but the cushion portion is not limited to this and may have a single structure or a multi-layer structure of three or more layers.

[0060] In the above-mentioned first to fourth embodiments, the cushioning materials 12, 32, and 42 formed using bubble cushioning material are exemplified as an example of the cushioning material. However, the cushioning material is not limited to this, and any material such as a urethane sheet or a rubber sheet can be used as long as it has an effect of absorbing external forces. However, as described above, the cost of the cushioning materials 12, 32, and 42 can be reduced by using bubble cushioning material, which is easily available. [Explanation of symbols]
