Description

[Technical Field]

[0001] The present invention relates to a packaging material for storing an object to be stored. [Background technology]

[0002] Conventionally, there has been known a service that connects product providers with each other via the Internet and mediates barter transactions (see, for example, Patent Document 1). When a trading partner appears, the product provider packages and ships the target product, and receives the exchange product from the trading partner who has packaged it in the same way. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-118673 Summary of the Invention [Problem to be solved by the invention]

[0004] In many cases, in the barter intermediary services described above, the provider of the goods must prepare various packaging materials, such as storage bags and cushioning materials, at their own discretion, and then package the goods to be stored. In this situation, not only is preparing packaging materials a burden, but the level of packaging varies, which may lead to problems between providers of goods.

[0005] Therefore, in order to solve the problems present in the prior art, the present invention aims to provide a packaging material that can perform packaging at a stable level while reducing the effort required by the person doing the packaging. [Means for solving the problem]

[0006] The packaging material that solves the above-mentioned problems is characterized by comprising a plurality of bags of different sizes, each having a storage opening, which form a nesting structure in which a relatively smaller bag is stored within a larger bag with the storage openings facing in the same direction, a plurality of storage bags in which an object to be stored is stored through the storage opening of the innermost bag, which is the innermost bag located on the inside, and a cushioning material that is provided as a member to absorb external forces and that covers the outer surface of the bag to be protected and is adhesively fixed to at least a part of the outer surface in a manner that allows the storage opening to be opened and closed. [Effects of the Invention]

[0007] The above-described packaging material allows packaging to be performed with a stable level while minimizing the work required by the packer. [Brief explanation of the drawings]

[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 A1, such as can badges or other items with a relatively flat shape. This packaging material 1 is sent for packaging by a platform provider that mediates the service to each provider of the items desired to be exchanged in an internet-based barter service. A logo or other mark identifying the platform provider is printed on the outermost surface of the packaging material 1, ensuring its quality. Upon receiving the packaging material 1, each provider stores and packages an item in the packaging material 1, and then sends it to the exchange partner by mail or other means. This packaging material 1 includes two storage bags 11 and a cushioning material 12.

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

[0013] A sealable flap 112c is provided at the opening 112a of the outermost bag 112, with a fold line 112b forming part of the opening edge. A strip of adhesive 112d for sealing is applied to the flap 112c across the entire width of the outermost bag 112, and the adhesive 112d is masked with masking tape 112e to prevent it from accidentally sticking. An object A1 to be stored is placed in the innermost bag 111 of these two storage bags 11 through the opening 111a of the innermost bag 111.

[0014] The cushioning material 12 is a member provided on the innermost bag 111 of the two storage bags 11 as the bag to be protected, 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 manner that allows the storage opening 111a to 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 near 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.

[0015] Furthermore, at least a portion 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 where opening and closing the storage opening 111a of the innermost bag 111, which is the bag to be protected and located inside the cushioning material 12, can be opened and closed by opening and closing the storage opening 112a of the outermost bag 112. Furthermore, the adhesive area 12a on the outer surface of this cushioning material 12 is only a portion near the storage opening 111a of the innermost bag 111. And, one adhesive area 12a on this 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] In this embodiment, the cushioning material 12 covers the entire outer surface, including the bottom 111c, of the innermost bag 111, which is the bag to be protected, and is provided in a bag shape with the orientation of the storage opening 12b aligned with the orientations of the storage openings 111a, 112a of the innermost bag 111 and the outermost bag 112. Furthermore, the cushioning material 12 is a double bag consisting 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 smaller bag than the outer cushioning bag 122, and the cushioning material 12 has a nested structure in which the inner cushioning bag 121 is housed within the outer cushioning bag 122 with the orientations of the inner storage opening 12b-1 and the outer storage opening 12b-2 aligned. Furthermore, the outer surface of the inner cushioning bag 121 and the inner surface of the outer cushioning bag 122 are adhesively fixed over a wide area to prevent separation 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 outer cushioning 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 bubble cushioning material.

[0017] The packaging of the object A1 using the packaging material 1 of this embodiment is performed as follows. First, the opening 112a of the outermost bag 112 is opened, which causes the opening 12b of the cushioning material 12 inside it and the opening 111a of the innermost bag 111 to be opened together. The object A1 is placed 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, exposing the strip-shaped adhesive glue 112d. Thereafter, the flap 112c is folded along the crease 112b, and the flap 112c is adhesively fixed to the outer surface of the outermost bag 112 with the adhesive glue 112d, thereby sealing the object A1 and completing the packaging of the object A1. The above work is performed by each provider of goods who receives packaging material 1 from the platform operator who mediates the barter service. Once the provided goods are packed as storage objects A1 in packaging material 1, each 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, has been 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 of the nested structure, and the cushioning material 12, which protects the innermost bag 111, covers its outer surface. Therefore, the object A1 contained in this packaging material 1 is stably protected by the cushioning material 12 from external forces during transport. Furthermore, since the cushioning material 12 is adhesively fixed to a portion of the outer surface of the innermost bag 111 in a state in which the opening 111a can be opened and closed, the opening 111a of the innermost bag 111 can be opened together with the cushioning material 12 to contain the object A1, thereby reducing the effort required for packaging. Thus, the packaging material 1 described above enables stable packaging while minimizing the effort required for the packer.

[0020] In this embodiment, the cushioning material 12 is adhesively fixed only to a portion of the outer surface of the innermost bag 111, which is the bag to be protected, that is close to 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] Furthermore, in this embodiment, 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 closest to the storage opening 111a of the innermost bag 111 is adhesively 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 cushioning material 12 from shifting in position in the depth direction of the innermost bag 111. Furthermore, compared to a case where cushioning material is provided individually on each side 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 reduces the effort required for taping and the like.

[0024] In this embodiment, the cushioning material 12 double-wraps and covers the outer surface of the innermost bag 111. With this configuration, the cushioning material 12 is provided so as to double-wrap around the bag, thereby enhancing 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 sealable flap 112c, with part of the opening edge forming a fold line 112b. This configuration reduces the labor required for sealing the bag for waterproofing purposes after the storage object A1 is stored. Furthermore, because the sealing flap 112c is provided with part of the opening edge of the storage opening 112a of the outermost bag 112 as the fold line 112b, the flap 112c is bent at a specific position to seal the bag. This allows even an inexperienced person to perform highly waterproof sealing.

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

[0028] In this embodiment, the cushioning material 12 is formed using 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 articles to be stored and the shape of the innermost bag in which these articles are stored. The following description of the second embodiment will focus 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 assigned the same reference numerals as in Fig. 3 only for those components necessary for explanation, and redundant explanations of the equivalent components will be omitted below.

[0031] The packaging material 2 of this embodiment is a bag-shaped member that stores a small three-dimensional structure, such as a capsule toy, as a storage object A2. Similar to the first embodiment, this packaging material 2 includes a slightly larger outermost bag 112 and a cushioning material 12 formed into a double-bag shape using bubble cushioning material. Meanwhile, in this embodiment, the innermost bag 211, which together with the outermost bag 112 constitutes two storage bags 21, is large enough to store a small three-dimensional structure, and its storage opening 211a is also provided with a sealable flap 211c. Similar to the flap 112c of the outermost bag 112, the flap 211c of this innermost bag 211 is provided with a fold line 211b along part of the opening edge of the storage opening 211a.

[0032] In the packaging material 2 of this embodiment, the object A2, which is a small three-dimensional structure, is placed in the slightly larger innermost bag 211, and then sealed with the flap 211c of the innermost bag 211. This sealing is achieved by peeling the masking tape 212e from the flap 212c of the innermost bag 211, exposing the strip-shaped adhesive glue 212d, and folding the flap 212c along the crease 212b, just like with the flap 112c of the outermost bag 112. This folding adheres and fixes the flap 212c to the outer surface of the innermost bag 212 with the adhesive glue 212d, thereby completing the sealing. The flap 112c of the outermost bag 112 is then sealed, completing the packaging of the object A2, which is a small three-dimensional structure, in the packaging material 2.

[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 with 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 explained above can also perform stable packaging at a low level while minimizing the work required of the packer, as in the first embodiment.

[0035] In this embodiment, the innermost bag 211 that contains the storage object A2 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 than the flat storage object A1.

[0036] Next, a third embodiment will be described. This third embodiment differs from the first embodiment in the shape of the stored items and the configuration of the cushioning material. Below, the third embodiment will be described, 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-shaped member that stores thin, easily deformable items, such as card-shaped items, as storage objects A3. This packaging material 3 includes a double storage bag 11 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, which uses the innermost bag 111 as the bag to be protected in this embodiment, is not bag-shaped, unlike the first embodiment, but has a configuration that sandwiches and holds the innermost bag 111, 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 that make up a folded cardboard box 323 made by folding a rectangular piece of cardboard 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] Cushion portion 322 is a rectangular sheet-like material attached to the outer surfaces of two rectangular flat plates 321, and in this embodiment has a double structure consisting of two overlapping rectangular bubble cushioning materials. This double-structured cushion portion 322 is folded in half at locations corresponding to crease line 321a of folding cardboard 323 and attached to the entire outer surfaces of each rectangular flat plate 321 to form bifold-shaped cushioning material 32. Furthermore, on the outer surface of cushion portion 322 of cushioning material 32, adhesive areas 32a for bonding with outermost bag 112 are provided near storage opening 111a of innermost bag 111. One adhesive area 32a is provided on each outer surface of bifold-shaped cushioning material 32, on the front and back sides, and is adhesively fixed to the inner surface of outermost bag 112.

[0041] The packaging material 3 of this embodiment is used to package a thin, easily deformed item, such as a card, as the storage object A3. During packaging, the storage opening 112a of the outermost bag 112 is opened, and the storage opening 111a of the innermost bag 111 is opened via the double-folded cushioning material 32, and the storage object A3 is placed into the innermost bag 111 through the storage opening 111a. Next, the masking tape 112e is peeled off the sealing flap 112c provided at the storage opening 112a of the outermost bag 112, exposing the strip-shaped adhesive glue 112d. Thereafter, the flap 112c is folded along the crease 112b, and the flap 112c is adhesively fixed to the outer surface of the outermost bag 112 with the adhesive glue 112d, thereby sealing the storage object A3 and completing the packaging of the storage object A3.

[0042] It goes without saying that the packaging material 3 of the third embodiment explained above can also perform packaging with a stable level while minimizing the work required by the packer, as in the first embodiment.

[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, thin and easily deformed items such as cards as the storage object A3 can be effectively protected by sandwiching them 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. This 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] As described above, the packaging material 4 of this embodiment is a bag-shaped member for storing relatively large items A4, such as stuffed toys. The basic structure of this packaging material 4 is the same as that of the first embodiment, and includes two storage bags 41, each consisting of an innermost bag 411 and an outermost bag 412 formed from a transparent resin sheet, and a cushioning material 42 formed into a double-bag shape from bubble cushioning material. The two storage bags 41 and the cushioning material 42 are such that the smallest innermost bag 411 is large enough to store an item A4, such as a stuffed toy, and the cushioning material 42 and the outermost bag 412 are sized to match the size of the innermost bag 411. 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] Furthermore, 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 allow sealing even when an A4 size item 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 minimizing the work required of the packer, similar to the first embodiment described above.

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

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

[0051] For example, in the first to fourth embodiments described above, packaging materials 1, 2, 3, and 4 are exemplified as examples of packaging materials, each of which includes two storage bags 11, 21, and 41: an innermost bag 111, 211, and an outermost bag 112, and which 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, or may be provided for each of the innermost bag and all or part of the other bags, with one cushioning material provided for each bag.

[0052] Furthermore, in the first to fourth embodiments described above, examples of the cushioning material are cushioning materials 12, 32, and 42 that are adhesively fixed only to a portion of the outer surface of the bag to be protected that is closer to the storage opening 111a, 211a, and 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. Even if the cushioning material is adhesively fixed only to a portion 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, a configuration in which cushioning material 12, 32, and 42 is adhesively fixed only to a portion of the outer surface of the bag to be protected that is closer to the storage opening 111a, 211a, and 411b can increase the degree of freedom in storing the items A1, A2, A3, and A4 to be stored.

[0053] Furthermore, in the above-described first to fourth embodiments, as an example of the cushioning material, cushioning materials 12, 32, 42 are illustrated as being adhesively fixed to the inner surface of the outer bag (outermost bag 112, 412) located outside the outer bag in a state in which the storage openings 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-adhered state. However, as described above, by adhesively 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 openings 111a, 211a, 411b of the bag to be protected can be opened and closed, the effort required for storage can be further reduced.

[0054] Furthermore, in the above-described first to fourth embodiments, as an example of the cushioning material, cushioning materials 12, 32, and 42 are illustrated in which only a portion of the outer surface of the cushioning material 12, 32, and 42 that is close to the storage opening 111a, 211a, and 411b of the bag to be protected is adhesively fixed to the inner surface of the outer bag (outermost bag 112, 412). However, the cushioning material is not limited to this, and the entire outer surface of the cushioning material 12, 32, and 42 may be adhesively fixed to the inner surface of the outer bag. Even if only a portion of the outer surface of the cushioning material 12, 32, and 42 that is close to the storage opening 111a, 211a, and 411b of the bag to be protected is adhesively fixed to the inner surface of the outer bag (outermost bag 112, 412), however, as described above, a configuration in which only a portion of the outer surface of the cushioning material 12, 32, and 42 that is close to the storage opening 111a, 211a, and 411b of the bag to be protected is adhesively fixed to the inner surface of the outer bag (outermost bag 112, 412) can increase the degree of freedom regarding storage.

[0055] Furthermore, 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, as an example of the cushioning material. However, the cushioning material is not limited to this, and may cover only a portion of the outer surface of the bag to be protected. However, as described above, by having the cushioning materials 12, 32, and 42 cover the entire outer surface of the bag to be protected, including the bottom 111c, it is possible to prevent the cushioning materials 12, 32, and 42 from shifting in position, and also to reduce the effort required to fasten the cushioning materials 12, 32, and 42 with tape, etc.

[0056] Furthermore, in the above-described first, second, and fourth embodiments, the cushioning materials 12 and 42 are exemplified as doubly surrounding and covering the outer surface of the bag to be protected. However, the cushioning material is not limited to this, and may be, for example, a material that covers the outer surface of the bag to be protected with only a single layer, as exemplified by the cushioning material 32 in the third embodiment. However, as described above, by doubly surrounding and covering the outer surface of the bag to be protected with the cushioning materials 12 and 42, the effect of absorbing external forces can be enhanced. Note that the number of cushioning materials is not limited to two, and three or more layers may be stacked to cover the outer surface of the bag to be protected.

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

[0058] Furthermore, in the above-described first to fourth embodiments, a plurality of storage bags 11, 21, 41 formed from a transparent resin sheet such as OPP are exemplified as an example of a plurality of storage bags. However, the plurality of storage bags are not limited to this, and all or part of the storage bags may be formed from an opaque material. However, as described above, forming all of the plurality of storage bags from a transparent resin sheet can give a sense of security to the recipient of the packaged items.

[0059] Furthermore, in the third embodiment described above, an example of a cushioning material is illustrated as a cushioning material 32 including two rectangular flat plates 321 and a cushion portion 322 that constitute a folded cardboard box 323. However, the cushioning material is not limited to this and may be, for example, a bag-shaped cushioning material, as illustrated in 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 can absorb external forces applied to the bag to be protected, cover the outer surface of the bag to be protected, and be adhesively fixed to at least a portion of the outer surface in a manner that allows the opening to 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 thin and easily deformed items, such as cards, as the storage object A3 and reduce the effects 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 being part of a folded member, such as the folded cardboard box 323. The two rectangular flat plates may be individually provided 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 addition, in the above-described third embodiment, the cushion portion 322 having a double structure is exemplified 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 first to fourth embodiments described above, the cushioning materials 12, 32, and 42 are formed using bubble cushioning material 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 the 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]
