Description

Technical Field

[0001] The present disclosure relates to a packaging package for collectibles.

Background Art

[0002] Footwear including sneakers or leather shoes and the like suffers from problems such as discoloration due to ultraviolet rays, hydrolysis of urethane used in sole portions caused by moisture that is particularly prone to occur in Japan under high temperature and high humidity conditions, or mold growth. To resolve these problems, it is conceivable to use airtight bags, storage containers, or the like. However, many of these are often shunned by collectors for reasons such as poor appearance.

[0003] For example, Patent Document 1 discloses a shoe storage bag characterized in that a bag made of a material capable of maintaining airtightness is shaped to fit the outer surface of a shoe, the foot insertion opening, and the inside of the foot insertion opening, and is provided with a shoe insertion opening that allows any shoe to be placed inside while maintaining airtightness, or a suction port for evacuating internal air. Further, Patent Document 2 discloses a compression bag characterized by having a zipper portion for sealing a bag body capable of storing shoes therein, and a bag body to be inserted into the interior of a shoe, so that air inside the shoe (the portion for inserting a foot) is evacuated to enable compression even from the inside of the shoe.

[0004] On the other hand, trading cards (also referred to as collectible cards) have gained popularity worldwide not only for gaming purposes but also as objects for appreciation or collection. Such trading cards have great variations in rarity or transaction price depending on differences in patterns, photographs, or types of special processing applied to the surface of a base material body mainly made of paper and / or polyolefin resin, and thus there is a demand for a package capable of storing trading cards for a long period of time.

[0005] For example, Patent Document 3 discloses a trading card comprising two card pieces, a front and a back, with windows at different positions; an intermediate card piece having an opening slightly larger than those windows; and a thin plate-like object that is approximately the same size as the opening of the intermediate card piece and related to the patterns provided on the two card pieces, the two card pieces being attached to the intermediate card piece so as to hold the thin plate-like object in the opening of the intermediate card piece.

There was room for improvement in terms of convenience for conventional packaging materials, including heat-shrinkable packaging materials.

[0008] Similarly, the trading cards described in Patent Document 3 also failed to adequately consider convenient packaging materials.

[0009] Therefore, the objective of this disclosure is to provide a packaging package for collected materials that can solve the problems of the above-mentioned prior art and improve convenience. [Means for solving the problem]

[Modes for carrying out the invention]

[0025] In the following, one embodiment of this disclosure will be mainly described with reference to the attached drawings.

[0026] Figure 1 is a schematic external perspective view showing an example of the disassembled configuration of a packaging package 1 for collectibles according to one embodiment of this disclosure. Figure 2 is a schematic external perspective view showing an example of the assembled configuration of the packaging package 1 of Figure 1. An example of the configuration and function of the packaging package 1 according to one embodiment will be mainly described with reference to Figures 1 and 2.

[0027] The packaging package 1 is, for example, a three-dimensional case used for packaging shoes S. The packaging package 1 has a three-dimensional shape that corresponds to the shape of the shoes S so that it can enclose the shoes S. The packaging package 1 may be formed in the shape of a shoe. Forming the packaging package 1 in the shape of a shoe can improve the appearance when the shoes S are packaged in it. The packaging package 1 is configured, for example, as a blister pack.

[0028] In this disclosure, “Shoe S” includes, for example, footwear designed to protect and support the wearer’s foot and to adequately mitigate contact with the ground. Shoes S include, for example, sneakers or leather shoes. Packaging 1 may be used, for example, by a collector for long-term storage of Shoes S for display, or by a retailer for short-term storage of Shoes S for sale. Packaging 1 may, for example, be configured as a completely transparent case to suit display purposes.

[0029] The packaging package 1 includes a container body 10, a lid 20, a mounting part 30, a sealing member 40, and a humidity indicator part 50.

[0030] The container body 10 has a recess 11 for accommodating the shoe S as a collection item. The recess 11 of the container body 10 is configured to conform to the shape of the shoe S's upper. In this disclosure, "configured to conform to the shape of the shoe S's upper" means, for example, that when the shoe S is placed in the packaging package 1, the recess 11 of the container body 10 maintains a three-dimensional shape so that the surface of the container body 10 conforms to the surface of each component of the shoe S, such as the toe, heel, opening, and sides, and covers the shoe S.

[0031] The container body 10 has an opening 13 for inserting and removing collected items, and a first surface 14 positioned relative to the opening 13. For example, the first surface 14 is positioned around the entire circumference of the opening 13, along the edge of the opening 13. In this disclosure, “collected items” include, for example, shoes S. The recess 11 of the container body 10 is positioned continuously with the opening 13 and accommodates the collected items.

[0032] The container body 10 is, for example, entirely transparent. The container body 10 is made of a transparent resin. In this disclosure, “transparent resin” includes, for example, at least one of polyethylene terephthalate (PET), polyvinyl chloride (PVC), and polypropylene (PP). As will be described later, the container body 10 may have a base layer comprising at least one of PET, PVC, and PP. The container body 10 may have, for example, a laminated structure, and its details will be described later, but it is not limited to this. The container body 10 does not have to have a laminated structure.

[0033] The container body 10 has UV-cutting and moisture-proof properties. For example, the base layer of the container body 10 may have UV-cutting and moisture-proof properties. Alternatively, or in addition, the container body 10 may have at least one of a UV-cutting layer and a barrier coating layer on the outer or inner side of the base layer. For example, the container body 10 may have at least one of a UV-cutting layer and a barrier coating layer on the outer side of the base layer, or at least one of a UV-cutting layer and a barrier coating layer on the inner side of the base layer. In this disclosure, "inner surface" means, for example, the surface facing the shoe S when the shoe S is packaged in the packaging package 1. "Outer surface" means the surface opposite to the inner surface.

[0034] The container body 10 is a sheet-like molded body. The thickness of the container body 10, that is, the thickness of the sheet constituting the container body 10, is, for example, in the range of 0.1 mm to 5.0 mm, more preferably 0.1 mm to 3.0 mm. The container body 10 is a thin sheet-like material that independently maintains a three-dimensional shape having a recess 11.

[0035] The lid 20 closes the recess 11 of the container body 10. The lid 20 is positioned opposite the bottom surface of the sole of the shoe S packaged in the packaging package 1. The lid 20 is a sheet-like base material. The lid 20 is a thin sheet and forms a flat plate shape. The lid 20 may be made of any resin having transparency or opacity, or of any other material other than resin, such as metal.

[0036] The lid 20 has a second surface 23. The second surface 23 is arranged around the entire circumference, for example, along the inside of the edge 21 of the lid 20. The lid 20 closes the opening 13 of the container body 10 by having the second surface 23 in contact with the first surface 14 of the container body 10.

[0037] The mounting portion 30 is integrally arranged along the edge 21 of the lid 20, which is, for example, composed of a flat plate shape. The mounting portion 30 has a mounting structure that attaches the container body 10 and the lid 20 to each other such that the lid 20 closes the recess 11 of the container body 10. The mounting structure of the mounting portion 30 includes, for example, an engagement structure, a locking structure, a fitting structure, an adhesive structure, a joining structure, or a screw structure. For example, the mounting portion 30 includes a fastener integrally provided on the edge 21 of the lid 20 that engages with or locks with the corresponding edge 12 of the container body 10 to fix the container body 10 to the lid 20. The mounting portion 30 attaches the container body 10 and the lid 20 to each other by applying stress to the first surface 14 and the second surface 23 that are in contact with each other.

[0038] The sealing member 40 is positioned on the surface of the lid 20. The sealing member 40 is positioned around the entire circumference of the shoe S, which is positioned on the surface of the lid 20 of the packaging package 1. The sealing member 40 is sandwiched between the first surface 14 and the second surface 23 and is positioned continuously along the entire circumference of the opening 13 of the container body 10. The sealing member 40 includes, for example, a packing, O-ring, gasket, or sealing material. The sealing member 40 seals the gap that occurs between the container body 10 and the lid 20, which are fitted together by the mounting portion 30, and plays a role in improving the airtightness inside the packaging package 1.

[0039] The humidity indicator unit 50 is positioned in the container body 10 and changes its state according to the humidity history inside the container body 10. In this disclosure, the "state" of the humidity indicator unit 50 includes, for example, color tone or hue. The humidity indicator unit 50 is configured such that, for example, its color tone or hue changes when it has absorbed a certain amount of water vapor according to the humidity history. The humidity indicator unit 50 is laminated integrally with the container body 10, for example, as described later, to form a laminated structure together with the container body 10. However, the humidity indicator unit 50 may be attached to the inner surface of the container body 10 as a separate component by any mounting method, including, for example, adhesive, joining, screwing, engaging, locking, or fitting.

[0040] When assembling the packaging 1, the container body 10 and the lid 20 are separated from each other, as shown in Figure 1. The container body 10 is positioned directly above the lid 20. The container body 10 moves downward toward the lid 20 and is pressed against it. At this time, the container body 10 is positioned toward the surface of the lid 20, sandwiching the sealing member 40 together with the lid 20.

[0041] The container body 10 and the lid 20, which are positioned relative to each other with the sealing member 40 in between, are fitted and fixed together by the mounting portion 30. At this time, the packaging package 1 is configured such that, for example, the container body 10 faces the main body portion 22 of the lid 20, excluding the entire circumference of the edge portion 21 of the lid 20, and the container body 10 fits inside the edge portion 21 of the lid 20 to connect, achieving the fitted state of the packaging package 1 by an internal fitting method. The main body portion 22 of the lid 20 is recessed by a step relative to the entire circumference of the edge portion 21 of the lid 20. The packaging package 1 can achieve high airtightness through this internal fitting method of fitting the container body 10 and the lid 20, and the placement of the sealing member 40 in the gap between the container body 10 and the lid 20.

[0042] The opening 13 of the container body 10 and the lid 20 are positioned relative to one of the following locations on the shoe S: the front, back, side, or bottom of the sole. For example, as shown in Figure 2, the opening 13 of the container body 10 and the lid 20 are positioned relative to the bottom of the sole of the shoe S when the packaging package 1 encloses the shoe S and the container body 10 and the lid 20 are fitted together.

[0043] The humidity indicator unit 50 is positioned so that it can be seen from the outside of the packaging package 1 even when the packaging package 1 is fitted together with the container body 10 and the lid 20 fitted together, due to the transparency of the container body 10. In the examples shown in Figures 1 and 2, the humidity indicator unit 50 is positioned at the corner of the container body 10. The humidity indicator unit 50 facilitates external visibility of the packaging package 1 by the user.

[0044] Figure 3 is a schematic external perspective view showing another first example of the arrangement of the humidity indicator unit 50 placed on the container body 10 in Figure 1. Figure 4 is a schematic external perspective view showing another second example of the arrangement of the humidity indicator unit 50 placed on the container body 10 in Figure 1. Figure 5 is a schematic rear view showing another third example of the arrangement of the humidity indicator unit 50 placed on the container body 10 in Figure 1. The variations in the arrangement of the humidity indicator unit 50 in the packaging package 1 will be mainly explained with reference to Figures 3 to 5. In Figures 3 to 5, for the purpose of simple illustration, the lid 20, mounting part 30, and sealing member 40 are omitted from the illustration, and only the arrangement relationship of the humidity indicator unit 50 in the container body 10 is mainly shown.

[0045] The humidity indicator unit 50 is located on at least a portion of the inner surface of the container body 10. The humidity indicator unit 50 is located on only a portion of the inner surface of the container body 10, for example, as shown in Figures 3 to 5. In the first example shown in Figure 3, the humidity indicator unit 50 is located on the inner surface of the container body 10 facing the opening of the shoe.

[0046] The humidity indicator unit 50 may be located on the inner surface of the container body 10 facing the surface of the shoe. In this disclosure, the “surface” of the shoe includes, for example, the side of the shoe or the back of the shoe located at the heel, adjacent to the bottom surface of the sole. For example, as shown in Figure 4, the humidity indicator unit 50 may be located on the inner surface of the container body 10 facing the side of the shoe. For example, as shown in Figure 5, the humidity indicator unit 50 may be located on the inner surface of the container body 10 facing the back of the shoe located at the heel, adjacent to the bottom surface of the sole.

[0047] The following section will primarily describe the layered structure of packaging 1.

[0048] <Definition> In this disclosure, "main component" refers to the component that is most abundant by mass.

[0049] <Packaging> An embodiment of the packaging package 1 of this disclosure will be described with reference to Figure 6. Figure 6 is a schematic cross-sectional view showing one embodiment of the packaging package 1.

[0050] As shown in Figure 6, the packaging package 1 comprises a base layer 2 and a humidity indicator layer 3. The base layer 2 corresponds to the container body 10. The humidity indicator layer 3 corresponds to the humidity indicator unit 50. The above-mentioned packaging package 1 is equipped with a humidity indicator layer 3, which changes its state according to the humidity history inside the packaging package 1. This can be visually detected, making it possible to determine when it is time for replacement.

[0051] In this disclosure, the “state” of the humidity indicator layer 3 includes, for example, color tone or hue. A change in the state of the humidity indicator layer 3 includes, for example, a change in color tone or hue. In this disclosure, "change in hue or color" of the humidity indicator layer 3 means that the hue or color before being affected by an external factor is different from the hue or color after being affected by the external factor. Hue refers to the tone of color determined by the relationship between lightness and saturation, and hue refers to the properties of color such as red, yellow, green, and blue. The external factor may be, for example, water vapor. Specifically, depending on the type or composition of the humidity indicator layer 3, this refers to a change from colorless to colored, a change from colored to colorless, a change from a first colored to a second colored, etc. From the viewpoint of appearance, a change from colorless to colored is preferable.

[0052] Packaging 1 may, for example, be configured as an entirely transparent case to suit display purposes.

[0053] Furthermore, the packaging 1 is preferably package-shaped so as to be able to enclose the collectibles inside. It is also preferable that the packaging 1 is formed to conform to the shape of the collectibles. The collectibles are not limited to, but examples include the shoes S mentioned above, and items that can be preserved for display, such as cards.

[0054] (base material layer) The base layer 2 is a layer that supports the humidity indicator layer 3. The base layer 2 may be the outermost layer of the packaging package 1. Therefore, one side of the base layer 2 may be in contact with the external atmosphere.

[0055] The base layer 2 may be a single layer or a laminate composed of two or more layers. From the viewpoint of preservation, it is preferable that the base layer 2 consists of two or more layers. By making the base layer 2 two or more layers, preservation can be improved, for example, by enhancing moisture resistance or UV protection. In addition, since the thickness of the packaging package 1 increases when the base layer 2 consists of two or more layers, wrinkles are less likely to occur, and as a result, a better appearance can be expected. Furthermore, if the base layer 2 is a single layer, the base layer 2 may consist of the first base layer 2a described later.

[0056] The average thickness of the substrate layer 2 is not limited, but can be, for example, 10 μm or more and 120 μm or less.

[0057] The average thickness of the base layer 2 is preferably 40% or more, and more preferably 50% or more, of the total thickness of the packaging package 1. A thickness of 45% or more of the total thickness of the packaging package 1 is preferable from the viewpoint of stable seal strength. Furthermore, from the viewpoint of transparency, the thickness of the base layer 2 is preferably 90% or less, and more preferably 80% or less, of the total thickness of the packaging package 1.

[0058] As shown in Figure 7, it is preferable that the base layer 2 has a first base layer 2a and a second base layer 2b. By having two base layers as the base layer 2 in this way, storage properties such as moisture resistance can be improved compared to when the base layer 2 is a single layer. In Figure 7, the first base layer 2a, the second base layer 2b, and the humidity indicator layer 3 are arranged in this order, but the arrangement is not limited to this, and the first base layer 2a may be provided adjacent to the humidity indicator layer 3. In other words, the second base layer 2b, the first base layer 2a, and the humidity indicator layer 3 may be laminated in this order.

[0059] The first base layer 2a and the second base layer 2b may be made of the same components or materials, or they may be made of different components or materials.

[0060] [First base layer] The first substrate layer 2a is a substrate layer 2 that supports the humidity indicator layer 3. The substrate layer 2 may consist only of the first substrate layer 2a, or it may have the first substrate layer 2a and other layers (for example, the second substrate layer 2b described later).

[0061] The first base material layer 2a is, but is not limited to, preferably a layer mainly composed of a polyolefin resin, polyester resin, or polyamide resin, and more preferably a layer made of a polyolefin resin, polyester resin, or polyamide resin. In this disclosure, "main component" refers to the component that is most abundant by mass among the components constituting the layer. Among these, from the viewpoint of moisture resistance, the first base layer 2a is preferably a layer mainly composed of polyolefin resin, more preferably made of polyolefin resin, and in other words, the first base layer 2a is more preferably a polyolefin resin film.

[0062] The polyolefin resin is preferably a resin having one or more α-olefin monomer units. The α-olefin monomers are preferably having 2 to 8 carbon atoms, and examples include ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, 3-methyl-1-pentene, 1-decene, etc., and one or more of these can be used in combination. Examples of preferred polyolefin resins include polyethylene resins and polypropylene resins.

[0063] Examples of the polyethylene-based resins mentioned above include ethylene homopolymers and ethylene-α-olefin copolymers. The α-olefin preferably has 3 to 8 carbon atoms, and examples include propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, 3-methyl-1-pentene, and 1-decene. One or more of these can be used in combination. Examples of polyethylene resins include low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), medium-density polyethylene (MDPE), high-density polyethylene (HDPE), and stretched polyethylene (OPE) and stretched polyethylene (BOPE) obtained by stretching any of these.

[0064] Examples of the polypropylene-based resins mentioned above include polypropylene homopolymers, propylene-α-olefin copolymers, and terpolymers of propylene, ethylene, and α-olefin. The above-mentioned polypropylene resin may have stereoregularity (tacticity). Specifically, it may have any of isotactic, syndiotactic, or attactic stereoregularity, or it may have multiple blocks having any of these stereoregularities. Preferably, the polypropylene resin has an isotactic pentad fraction (mmmm) of 0.5 or more, 0.6 or more, 0.7 or more, 0.8 or more, or 0.9 or more, which indicates the proportion of isotactic polypropylene. When the pentad fraction is indicated, it may also contain 50% or less, 40% or less, 30% or less, 20% or less, or 10% or less of syndiotactic and / or attactic polypropylene having stereoregularity other than isotactic polypropylene.

[0065] The above-mentioned propylene-α-olefin copolymer refers to a copolymer consisting of propylene and at least one selected from α-olefins. The above-mentioned propylene-α-olefin copolymer is preferably a copolymer consisting of propylene and at least one selected from ethylene and α-olefins having 4 to 20 carbon atoms, and more preferably a copolymer consisting of propylene and at least one selected from ethylene and α-olefins having 4 to 8 carbon atoms. Examples of the α-olefins having 4 to 20 carbon atoms include 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, 3-methyl-1-pentene, 1-decene, etc., and one or more of these can be used in combination. The copolymer may be in any form, such as a block copolymer or a random copolymer. As the above-mentioned propylene-α-olefin copolymer, a copolymer of propylene and at least one comonomer selected from ethylene comonomer, butene comonomer, hexene comonomer, and octene comonomer is preferred.

[0066] As the terpolymer of propylene, ethylene, and α-olefin described above, a terpolymer of propylene, ethylene, and an α-olefin such as butene, hexene, or octene can be suitably used. The terpolymer may be in any form, such as a block copolymer or a random copolymer. The polypropylene resins mentioned above may be resins polymerized using catalysts such as Ziegler-Natta catalysts, or resins polymerized using known catalysts such as metallocene catalysts. Preferred polypropylene resins include, for example, stretched polypropylene (OPP) and unstretched polypropylene (CPP).

[0067] Examples of the above-mentioned polyester resins include polyethylene terephthalate (PET), polybutylene terephthalate (BET), and polyethylene naphthalate (PEN).

[0068] Examples of the polyamide resins mentioned above include nylon (stretched nylon (ONy), unstretched nylon (CNy), nylon 6, nylon 66, nylon 11, nylon 12), MXD6, and the like.

[0069] Among the above, the first base material layer 2a is preferably made of stretched polypropylene (OPP), stretched polyethylene (OPE), polyethylene terephthalate (PET), or nylon, and from the viewpoint of excellent moisture resistance, it is preferably made of stretched polypropylene (OPP) or stretched polyethylene (OPE).

[0070] The average thickness of the first substrate layer 2a is not particularly limited, but can be, for example, 10 μm or more and 50 μm or less. The average thickness of the first substrate layer 2a is a value measured using a film thickness gauge.

[0071] [Second base layer] The second substrate layer 2b is one of the layers that may be provided as needed on the substrate layer 2 that supports the humidity indicator layer 3.

[0072] The second base layer 2b is not limited, but is preferably a layer mainly composed of a polyolefin resin, and more preferably a layer made of a polyolefin resin. The term "main component" refers to the component that is most abundant by mass among the components that make up the layer. Specific examples of polyolefin resins are the same as those described in the section on the first base material layer, and the explanation in that section will be used as a reference.

[0073] Furthermore, the second base material layer 2b is preferably made of a polypropylene resin or a polyethylene resin, and more preferably of unoriented polypropylene (CPP) or linear low-density polyethylene (LLDPE). The embodiments of the polypropylene resin and polyethylene resin are the same as those described in the section on the first base material layer, and the explanation in the section on the first base material layer will be applied accordingly.

[0074] Furthermore, a preferred combination of the first base layer 2a and the second base layer 2b is one in which one of the first base layer 2a and the second base layer 2b is made of polyethylene resin and the other is made of polypropylene resin. With such a combination of layers, the packaging package 1 has higher moisture resistance and better preservation properties. More specifically, preferred combinations of the first base layer 2a and the second base layer 2b include a combination of stretched polypropylene (OPP) and unstretched polypropylene (CPP), a combination of stretched polypropylene (OPP) and linear low-density polyethylene (LLDPE), a combination of stretched polyethylene (OPE) and unstretched polypropylene (CPP), and a combination of stretched polyethylene (OPE) and linear low-density polyethylene (LLDPE).

[0075] The average thickness of the second substrate layer 2b is not particularly limited, but can be, for example, 20 μm or more and 120 μm or less. The average thickness of the second substrate layer 2b is a value measured using a film thickness gauge.

[0076] [Functional Layer] As shown in Figure 8, it is preferable that the packaging package 1 of this disclosure has a functional layer 2c as part of the container body 10 between the first base layer 2a and the second base layer 2b described above. By providing the functional layer 2c, the shelf life of the packaging package 1 can be improved. The functional layer 2c is not limited to, but examples include a UV-cutting layer and a barrier coating layer. The functional layer 2c may be a single layer or two or more layers. A suitable functional layer 2c is an ultraviolet-cutting layer and / or a barrier coating layer; in other words, preferably, an ultraviolet-cutting layer and / or a barrier coating layer are provided between the first base layer and the second base layer. By providing an ultraviolet-cutting layer, discoloration of the shoes due to ultraviolet rays can be suppressed. Furthermore, by providing a barrier coating layer, gas barrier properties and moisture resistance can be improved.

[0077] -UV (ultraviolet) cut layer- The ultraviolet (UV) cut layer is a layer that has the function of blocking at least a portion of ultraviolet light, for example, at least a portion of light with a wavelength of 300 nm to 380 nm. By having such a layer, discoloration of shoes caused by ultraviolet irradiation can be suppressed.

[0078] The UV-blocking layer can be, for example, a layer in which a material that absorbs or blocks ultraviolet rays (hereinafter also referred to as "UV-blocking agent") is dispersed in a resin.

[0079] Examples of UV-blocking agents that can be used include inorganic UV-blocking agents such as zinc oxide, titanium dioxide, cerium oxide, and iron oxide, as well as organic UV-blocking agents such as benzotriazole and benzophenone. Furthermore, examples of resins included in the UV-cutting layer include polyurethane resin, vinyl chloride-vinyl acetate copolymer, cellulose resin, vinyl chloride-acrylic copolymer resin, ethylene-vinyl acetate copolymer resin, vinyl acetate resin, acrylic resin, polyester resin, alkyd resin, polyvinyl chloride resin, rosin resin, rosin-modified maleic acid resin, terpene resin, phenol-modified terpene resin, ketone resin, cycloadhesive rubber, chlorinated rubber, butyral, polyacetal resin, petroleum resin, and modified resins thereof. These resins can be used individually or in mixtures of two or more.

[0080] The UV-blocking layer can be formed, for example, by applying an ink in which a material that absorbs or blocks the above-mentioned ultraviolet rays is dispersed in a resin to the base layer 2 (first base layer 2a or second base layer 2b).

[0081] The average thickness of the UV-blocking layer is not particularly limited, but for example, it can be between 0.1 μm and 6 μm. The average thickness of the UV-blocking layer is a value measured by cross-sectional analysis using a scanning electron microscope (SEM).

[0082] -Barrier Coat Layer- The barrier coating layer has at least gas barrier properties or moisture resistance. By providing the barrier coating layer, the gas barrier properties and / or moisture resistance of the packaging 1 can be improved.

[0083] The barrier coat layer is not limited to, but preferably consists of at least one of polyvinylidene chloride, an aluminum oxide vapor-deposited layer, or a silica vapor-deposited layer.

[0084] The barrier coating layer can be formed, for example, by applying a component that forms the barrier coating layer, such as polyvinylidene chloride, to the base layer 2 (first base layer 2a and / or second base layer 2b).

[0085] The average thickness of the barrier coating layer is not particularly limited, but for example, it can be between 10 nm and 30 μm. The average thickness of the barrier coating layer is a value measured by cross-sectional analysis using a scanning electron microscope (SEM).

[0086] [Adhesive layer] An adhesive layer may be provided between the first base layer 2a and the second base layer 2b, if necessary, for bonding the first base layer 2a and the second base layer 2b together. The adhesive forming the adhesive layer is not particularly limited as long as it is transparent and can bond the first base layer 2a and the second base layer 2b together, but examples include polyether urethane and polyester urethane. Furthermore, if a functional layer 2c is provided between the first base layer 2a and the second base layer 2b, the functional layer 2c can be formed by first forming the functional layer 2c on the first base layer 2a and / or the second base layer 2b, then applying an adhesive to the first base layer 2a and / or the second base layer 2b, and joining the two layers together. Furthermore, the adhesive layer is not limited to being provided between the first base layer 2a and the second base layer 2b, but may be provided between any two layers as needed.

[0087] The average thickness of the adhesive layer is not particularly limited, but for example, it can be between 1 μm and 6 μm. The average thickness of the adhesive layer is a value measured by cross-sectional analysis using a scanning electron microscope (SEM).

[0088] (others) UV-blocking properties may be imparted to one or more layers selected from the group consisting of the first base layer 2a, the second base layer 2b, the UV-cut layer, the barrier coat layer, and the adhesive layer. In other words, in the packaging package 1 of this disclosure, it is preferable that one or more layers selected from the group consisting of the first base layer 2a, the second base layer 2b, the barrier coat layer, and the adhesive layer have UV-blocking properties. By having these layers have UV-blocking properties, the UV-blocking properties of the packaging package 1 as a whole can be further improved. Furthermore, if an adhesive layer is not provided, it is preferable that one or more layers selected from the group consisting of the first base layer 2a, the second base layer 2b, and the barrier coat layer have UV-blocking properties.

[0089] One method for imparting UV-blocking properties to layers such as the first substrate layer 2a and the second substrate layer 2b is to use UV-blocking ink.

[0090] Furthermore, the surface of each layer may be subjected to any surface treatment. Examples of such surface treatments include corona treatment, ozone treatment, and flame treatment.

[0091] (Humidity indicator layer) The packaging package 1 of this disclosure includes a humidity indicator layer 3. When the humidity indicator layer 3 absorbs a certain amount of water vapor, its state changes. By visually detecting the change in the state of the humidity indicator layer 3, it is possible to determine when the packaging package 1 needs to be replaced. In this disclosure, "change in state" refers to, for example, a change in color tone or a change in hue.

[0092] The humidity indicator layer 3 is preferably composed such that its color (e.g., hue) changes between a state in which it does not absorb water vapor and a state in which it absorbs a certain amount of water vapor. The humidity indicator layer 3 can be formed from a composition including, for example, cobalt chloride, an organic dye, a binder resin, and a nonwoven fabric with good moisture absorption.

[0093] Examples of organic dyes include methyl violet, brilliant green, food green No. 3, food blue No. 3, and humidifier B.

[0094] Examples of binder resins include polyvinyl alcohol, polyurethane, acrylic resin, polystyrene sulfonic acid, and polyallylamine.

[0095] Examples of non-woven fabrics with good moisture absorption include polypropylene, polyethylene, and polyester.

[0096] The proportions of each material in the composition forming the humidity indicator layer 3 can be appropriately set to adjust the intensity of the color or the amount of absorbed water vapor that causes a color change.

[0097] Furthermore, the humidity indicator layer 3 does not need to be provided over the entire container body 10 of the packaging package 1, but may be formed only on a part of the container body 10 of the packaging package 1. When the humidity indicator layer 3 is provided on a part of the packaging package 1, it can be provided, for example, on the part corresponding to the opening of the shoe, the part corresponding to the bottom of the shoe, the part corresponding to the heel of the shoe, the part corresponding to the side of the shoe, etc. Furthermore, the humidity indicator layer 3 may be formed by attaching it to at least one surface of the packaging package 1, or it may be formed by laminating it as part of the layer structure of the packaging package 1. From the viewpoint of design freedom for the packaging package 1, it is preferable that the humidity indicator layer 3 is formed by attaching it to the packaging package 1. On the other hand, from the viewpoint of aesthetics for the packaging package 1, it is preferable that the humidity indicator layer 3 is formed by laminating it as part of the layer structure of the packaging package 1. When the humidity indicator layer 3 is formed by attaching it to the packaging package 1, if the packaging package 1 has a back surface, it is preferable to attach the humidity indicator layer 3 from the back surface. Furthermore, the humidity indicator layer 3 may have a pattern shape that displays characters or images when viewed from above.

[0098] The humidity indicator layer 3 can be formed, for example, by applying the above-described composition to the substrate layer 2. However, it is not limited to this, and the humidity indicator layer 3 may also be formed by pre-forming the above-described composition into a sheet or the like, and then adhering the formed composition to the substrate layer 2.

[0099] Examples of the discoloration patterns (changes in color tone or hue) of the humidity indicator layer 3 include, but are not limited to, a discoloration pattern in which the color changes from colorless to colored, or a discoloration pattern in which the first color changes to a second color.

[0100] The average thickness of the humidity indicator layer 3 is not particularly limited, but for example, it can be 100 μm or more and 5000 μm or less, preferably 100 μm or more and 500 μm or less. The average thickness of the humidity indicator layer 3 is a value measured by cross-sectional analysis using a scanning electron microscope (SEM).

[0101] (Physical properties of packaging, etc.) -Packaging thickness- The container body 10 of the packaging package 1 of this disclosure preferably has a thickness of 0.1 mm or more and 5.0 mm or less. Having a certain thickness makes the packaging package 1 aesthetically pleasing. Furthermore, for transparency, the thickness of the container body 10 of the packaging package 1 is more preferably 0.1 mm or more and 3.0 mm or less. The thickness of packaging 1 can be measured with a film thickness gauge.

[0102] -Water vapor transmission- The packaging package 1 of this disclosure has a water vapor transmission rate of 20 g / m² at 40°C and 90% RH. 2 It is preferable that the water vapor permeability is less than or equal to the above upper limit. By having a water vapor transmission rate of the packaging package 1 that is less than or equal to the above upper limit, the packaging package 1 becomes a packaging package 1 with excellent moisture resistance. From the viewpoint of moisture resistance, the water vapor permeability of packaging 1 should be as low as possible, and is 10 g / m² under conditions of 40°C and 90% RH. 2 It is more preferable that it be less than 5 g / m². 2 It is even more preferable that it be less than or equal to one day. The water vapor transmission rate of packaging 1 is measured using the isobaric method with a PARMATRAN3 / 33 (Mokon Corporation: water vapor transmission rate measuring device) under conditions of 40°C and 90% RH. Furthermore, the water vapor transmission rate of the packaging 1 can be reduced to below the above upper limit by, for example, adjusting the material used in the base layer 2 or by providing a barrier coat layer.

[0103] -UV transmittance- The packaging package 1 of this disclosure preferably has an ultraviolet transmittance of 15% or less at wavelengths of 360 nm or less. By keeping the ultraviolet transmittance of the packaging package 1 below the above upper limit, discoloration of shoes due to ultraviolet light can be suppressed. From a similar viewpoint, the ultraviolet transmittance of the packaging package 1 is more preferably 5% or less, and even more preferably 1% or less. In one embodiment, the ultraviolet transmittance may be 30% or more, depending on the balance with other transparency, etc. UV transmittance (%) = Average transmittance of ultraviolet light with a wavelength of 300-360 nm Ultraviolet transmittance is measured using a UV-Vis-Near-Infrared Spectrophotometer (SIMADZU, UV-3600). The ultraviolet transmittance can be reduced to or below the above upper limit by providing an ultraviolet-cutting layer or by giving ultraviolet-cutting properties to the layer provided in the packaging 1.

[0104] -Hayes- From the viewpoint of transparency, the packaging package 1 of this disclosure preferably has a haze of 40% or less. When the haze of packaging package 1 is below the above upper limit, it becomes a packaging package with excellent transparency and appearance. From the same viewpoint, it is more preferable that the haze of packaging package 1 be 10% or less. However, depending on the balance with other physical properties, the haze may be 5% or more. The haze of packaging package 1 is a value measured using a haze meter in accordance with JIS K7105.

[0105] -Oxygen permeability- The packaging package 1 of this disclosure has an oxygen permeability of 200 cc / m³ under conditions of 23°C and 0% RH. 2It is preferable that the water vapor permeability of the packaging package 1 is less than or equal to the above upper limit. By having a water vapor permeability of the packaging package 1 that is less than or equal to the above upper limit, the packaging package 1 becomes excellent in preventing mold growth and suppressing discoloration of sneakers due to oxidation. The water vapor permeability of packaging 1 is preferably as low as possible from the viewpoint of preventing mold growth and suppressing discoloration of sneakers due to oxidation, and is 100 cc / m³ under conditions of 23°C and 0% RH. 2 It is more preferable that it be less than 50cc / m 2 It is even more preferable that it be less than or equal to one day. The oxygen permeability of packaging 1 is measured using an OX-TRAN2 / 22 (Mokon Co., Ltd.: oxygen permeability measuring device) in accordance with JIS-K7126 (isobaric method) under an atmosphere of 23°C and 0% RH. Furthermore, the oxygen permeability of the packaging 1 can be kept below the above upper limit by, for example, adjusting the material used in the base layer 2 or by providing a barrier coat layer.

[0106] (Packaging) In the packaging package 1 of this disclosure, a humidity indicator layer 3 is laminated on one side of the base material layer 2, and the package covers the shoe so that the side with the laminated humidity indicator layer 3 can come into contact with the shoe. In other words, the humidity indicator layer 3 is provided on the inner surface of the packaging package 1 that faces the shoe. By providing the humidity indicator layer 3 on the inner surface of the packaging package 1 in this way, the amount of water vapor inside the packaging package 1 can be visualized, and the time for replacement can be confirmed.

[0107] In the packaging package 1, the humidity indicator layer 3 may be provided on the entire surface of the container body 10 of the packaging package 1, or on a portion of the surface of the container body 10 of the packaging package 1. When the humidity indicator layer 3 is provided on a portion of the surface of the container body 10 of the packaging package 1, for example, the humidity indicator layer 3 may be provided on the inner surface of the packaging package 1 facing the opening of the shoe, the inner surface of the packaging package 1 facing the side of the shoe, the inner surface of the packaging package 1 facing the part adjacent to the bottom on the back of the shoe where the heel is located, and the inner surface of the packaging package 1 facing the bottom of the shoe.

[0108] (Method of manufacturing packaging) The packaging package 1 of this disclosure can be manufactured by applying a composition for forming the humidity indicator layer 3 to a base layer 2, drying it to form a laminated sheet, and then molding and bonding it into a predetermined shape (e.g., the shape of a shoe). Alternatively, instead of applying the composition for forming the humidity indicator layer 3, the composition for forming the humidity indicator layer 3 may be formed in advance into a sheet and then attached to the packaging package. Furthermore, if the base material layer 2 consists of two or more layers, it can be manufactured by lamination using an adhesive.

[0109] The following sections will primarily describe the effects of the invention and its variations.

[0110] According to the packaging package 1 of the above embodiment, it is possible to improve convenience. The packaging package 1 has a recess 11 for accommodating shoes and comprises a sheet-like container body 10 made of transparent resin and a sheet-like lid 20 that closes the recess 11. As a result, the packaging package 1 allows shoes to be easily packaged by enclosing the shoes and closing the recess 11 of the container body 10 with the lid 20.

[0111] Unlike heat-shrinkable packaging materials, packaging package 1 is reusable and does not require special techniques such as heat shrinking for packaging. Packaging package 1 allows users to easily package display shoes without spending time or effort. Packaging package 1 also makes it easy to remove the packaged shoes from the package. As a result, packaging package 1 makes it easy to put shoes in and take them out.

[0112] The packaging package 1 improves airtightness inside the bag and thus enhances preservation by sealing the inside of the container body 10 with the lid 20, thereby closing the recess 11 of the container body 10. In addition, the packaging package 1 has UV-blocking properties, which suppresses discoloration of shoes packaged in the packaging package 1 due to ultraviolet rays. The packaging package 1 has moisture-resistant properties, which suppresses hydrolysis or mold growth of the polyurethane used in the sole of the shoes due to moisture. The packaging package 1 can improve both convenience and the preservation of shoes.

[0113] The packaging package 1 can achieve high airtightness through the internal fitting of the container body 10 and the lid 20, and the placement of a sealing member 40 in the gap between the container body 10 and the lid 20. For example, the packaging package 1 can achieve high airtightness by having a sealing member 40 sandwiched between the first surface 14 of the container body 10 and the second surface 23 of the lid 20, and continuously arranged along the entire circumference of the opening 13. Therefore, the packaging package 1 can further improve the preservation of shoes packaged in the packaging package 1.

[0114] The packaging package 1 has a sheet-like container body 10 made of transparent resin, making it possible to make the container body 10 entirely transparent. Therefore, the packaging package 1 can also improve the appearance of the shoes packaged in it. In addition, the packaging package 1 can further improve the appearance of the shoes when packaged by having the recessed parts 11 of the container body 10 conform to the shape of the shoe's upper. The packaging package 1 can improve convenience and preservation as well as the appearance of the packaged shoes.

[0115] As described above, packaging package 1 can achieve the desired appearance, preservation, and convenience of the packaged shoes.

[0116] The mounting portion 30 of the packaging package 1 applies stress to the first surface 14 and the second surface 23 that are in contact with each other, thereby attaching the container body 10 and the lid 20 to each other. This makes it easy to attach the container body 10 and the lid 20 to the packaging package 1, and makes it easy to achieve a fitted state in which the container body 10 and the lid 20 are fitted together.

[0117] The packaging package 1 further includes a humidity indicator unit 50 that changes its state according to the humidity history inside the container body 10. This makes it possible to determine when the packaging package 1 needs to be replaced. The packaging package 1 can easily inform the user of when it needs to be replaced, for example, by making the user perceive a change in the state of the humidity indicator unit 50. For example, the packaging package 1 can easily inform the user of when it needs to be replaced by visually communicating a change in the color tone or hue of the humidity indicator unit 50.

[0118] The humidity indicator unit 50 is positioned on the inner surface of the container body 10 facing the surface of the shoe. This allows the packaging package 1 to position the humidity indicator unit 50 in a location easily visible to the user storing the shoes packaged in the packaging package 1. The user can easily see the humidity indicator unit 50 even when, for example, the shoes are packaged in the packaging package 1 and stored for display.

[0119] The humidity indicator unit 50 is positioned on the inner surface of the container body 10 facing the opening of the shoe. This allows the packaging package 1 to position the humidity indicator unit 50 in a location that is easily visible to the user storing the shoes packaged in the package 1, but is not particularly conspicuous. Therefore, the packaging package 1 can maintain the appearance of the packaged shoes. The user can easily check the humidity indicator unit 50 even when, for example, the shoes are packaged in the packaging package 1 and stored for display. The user can also appreciate the shoes packaged in the packaging package 1 in an aesthetically pleasing manner.

[0120] The surface of the shoe includes the portion adjacent to the bottom surface of the sole on the side or back of the shoe. This allows the packaging package 1 to position the humidity indicator section 50 in a location easily visible to the user storing the shoes packaged in the packaging package 1. The user can, for example, check the humidity indicator section 50 in a location that they frequently view when admiring the shoes packaged in the packaging package 1. Therefore, the user can also quickly determine when it is time to replace the packaging package 1.

[0121] The container body 10 has a base layer containing at least one of PET, PVC, and PP. This makes it possible to make the entire container body 10 transparent using these transparent resins. Thus, the packaging package 1 can improve the appearance of the shoes packaged in it.

[0122] The base material layer of the container body 10 has UV-blocking and moisture-proof properties. As a result, the packaging package 1 can suppress discoloration of shoes packaged in the packaging package 1 due to ultraviolet rays. The packaging package 1 can suppress hydrolysis or mold growth of the urethane used in the sole of the shoes due to moisture. The packaging package 1 can improve the shelf life of the shoes.

[0123] The container body 10 has at least one of a UV-cutting layer and a barrier coating layer on the outer or inner surface of the base material layer. The packaging package 1, with its UV-cutting layer, can suppress discoloration of shoes due to ultraviolet light. The packaging package 1, with its barrier coating layer, can improve the gas barrier and moisture resistance inside the container body 10. Therefore, the packaging package 1 can suppress hydrolysis or mold growth of the urethane used in the sole of the shoes due to moisture. The packaging package 1 can improve the shelf life of the shoes.

[0124] The thickness of the container body 10 is within the range of 0.1 mm to 5.0 mm, or 0.1 mm to 3.0 mm. This allows the packaging package 1 to be constructed with a thin, sheet-like container body 10. Therefore, the packaging package 1 can improve the appearance of the shoes packaged in it.

[0125] It will be apparent to those skilled in the art that this disclosure can be implemented in other predetermined forms besides the embodiments described above without deviating from its spirit or essential features. Therefore, the prior description is illustrative and not limiting. The scope of the disclosure is defined not by the prior description but by the added claims. Any modifications within their equivalent scope are included therein.

[0126] For example, the shape, pattern, size, arrangement, orientation, type, and number of each component described above are not limited to those shown in the above description and drawings. The shape, pattern, size, arrangement, orientation, type, and number of each component may be configured arbitrarily as long as they can achieve their function. Each component of the illustrated packaging package 1 is a functional concept, and the specific form of each component is not limited to those shown.

[0127] In the above embodiment, the packaging package 1 was described as having an attachment portion 30 that attaches the container body 10 and the lid 20 to each other by applying stress to the first surface 14 and the second surface 23 that are in contact with each other, but it is not limited to this. The packaging package 1 may have other attachment structures that can attach the container body 10 and the lid 20 to each other, instead of or in addition to the attachment portion 30.

[0128] In the above embodiment, the packaging package 1 is described as having a humidity indicator unit 50 placed in the container body 10 and changing its state according to the humidity history inside the container body 10, but it is not limited to this. The packaging package 1 does not have to have a humidity indicator unit 50.

[0129] In the above embodiment, the humidity indicator unit 50 was described as being located on the inner surface of the container body 10 facing the surface of the shoe or on the inner surface of the container body 10 facing the opening of the shoe, but it is not limited to this. The humidity indicator unit 50 may be located on any other part of the container body 10. For example, the humidity indicator unit 50 does not have to be located on the inner surface of the container body 10, as long as it is possible to change its state according to the humidity history inside the container body 10.

[0130] In the embodiments described above, the surface of the shoe includes, but is not limited to, portions of the side or back of the shoe adjacent to the bottom surface of the sole. The surface of the shoe may include any other surface of the shoe.

[0131] In the above embodiment, the state of the humidity indicator unit 50 was described as including, for example, color tone or hue, but is not limited thereto. The state of the humidity indicator unit 50 may include, for example, a state that affects the sense of smell, such as odor, or a state that affects the sense of hearing, such as sound, in addition to, a state that affects the sense of sight, such as color tone or hue.

[0132] In the above embodiment, the container body 10 was described as having a base layer containing at least one of PET, PVC, and PP, but is not limited thereto. The resin material contained in the base layer of the container body 10 may be any other resin material that can maintain the transparency of the container body 10, instead of or in addition to at least one of PET, PVC, and PP.

[0133] In the above embodiment, the base layer of the container body 10 was described as having ultraviolet-blocking and moisture-proof properties, but it is not limited to this. The base layer of the container body 10 does not have to have at least one of ultraviolet-blocking and moisture-proof properties.

[0134] In the above embodiment, the container body 10 was described as having at least one of an ultraviolet-cutting layer and a barrier coating layer on the outer or inner side of the base layer, but it is not limited to this. The container body 10 may have a layer structure that does not include either an ultraviolet-cutting layer or a barrier coating layer, or it may not have a layer structure at all.

[0135] In the above embodiment, the thickness of the container body 10 was described as being in the range of 0.1 mm to 5.0 mm or 0.1 mm to 3.0 mm, but it is not limited to this. The thickness of the container body 10 may be in any other numerical range as long as the container body 10 can be constructed in a sheet-like form.

[0136] In the above embodiment, the packaging package 1 is described as being arranged so that the container body 10 faces the main body 22 of the lid 20, excluding the entire circumference of the edge 21 of the lid 20, and the fitting state of the packaging package 1 is achieved by an internal fitting method in which the container body 10 fits inside the edge 21 of the lid 20 and is connected. However, the packaging package 1 may achieve the fitting state by other internal fitting methods. For example, the packaging package 1 may achieve the fitting state of the packaging package 1 by an internal fitting method in which the main body 22 of the lid 20, excluding the entire circumference of the edge 21 of the lid 20, fits inside the container body 10 and is connected. In this case, the main body 22 of the lid 20 may, for example, protrude by one step relative to the entire circumference of the edge 21 of the lid 20.

[0137] The above embodiments primarily describe a shoe packaging package 1, but are not limited thereto. The packaging package 1 of this disclosure may also be for cards. That is, the collectibles may include cards.

[0138] In this disclosure, “card” includes, for example, collectible cards such as trading cards and postcards. Here, “trading card” refers to a card medium such as paper, resin, or metal, on which various types of images, photographs, documents, etc., such as individually different characters, are printed. Packaging 1 may be used, for example, by collectors for long-term storage for viewing and preservation, or by retailers for short-term storage for sale.

[0139] Figure 9A is a schematic external perspective view showing an example of the configuration of the disassembled packaging package 1 according to the first modified example of this disclosure. An example of the configuration of the packaging package 1 according to the first modified example will be mainly described with reference to Figure 9A. The packaging package 1 according to the first modified example differs from the above embodiment in that it contains a card S as a collectible.

[0140] The packaging package 1 for the card S may have a container body 10, similar to the embodiment described above, having an opening 13 for inserting and removing the card S as collectibles, and a first surface 14 positioned relative to the opening 13. However, the recess 11 of the container body 10 may be configured in a rectangular parallelepiped shape to conform to the shape of a single card or a set of multiple stacked cards S.

[0141] The packaging package 1 for the card S may have a second surface 23, and a lid 20 that closes the opening 13 by the second surface 23 contacting the first surface 14, similar to the embodiment described above. In addition, the packaging package 1 for the card S may have a sealing member 40 that is sandwiched between the first surface 14 and the second surface 23 and continuously arranged along the entire circumference of the opening 13, similar to the embodiment described above. In this case, the container body 10 may have UV-cutting and moisture-proof properties, similar to the embodiment described above.

[0142] The mounting portion 30 may be partially positioned at the center of one side of the edge portion 21 of the lid 20, as shown in Figure 1, or it may extend along the entire length of that side, as newly shown in Figure 9A.

[0143] Figure 9B is a schematic external perspective view showing an example of the configuration of the disassembled packaging package 1 according to the second modified example of this disclosure. An example of the configuration of the packaging package 1 according to the second modified example will be mainly described with reference to Figure 9B. The packaging package 1 according to the second modified example is the same as the first modified example in that it contains cards S as collectibles, but the number of recesses 11 in the container body 10 is different.

[0144] For example, the packaging package 1 for the card S may have multiple recesses 11 in the container body 10. The multiple recesses 11 in the container body 10 may be formed at positions corresponding to the arrangement of multiple cards S, or multiple sets of multiple cards stacked on top of each other, arranged in the planar direction of the lid 20.

[0145] Figure 10 is a schematic external perspective view showing an example of the configuration of the disassembled packaging package 1 according to the third modified example of this disclosure. Figure 11 is a schematic external perspective view showing an example of the configuration of the fitted packaging package 1 of Figure 10. An example of the configuration of the packaging package 1 according to the third modified example will be mainly described with reference to Figures 10 and 11.

[0146] In the above embodiment, the container body 10 was described as having a recess 11 that conforms to the shape of the upper of the shoe S contained in the collection, but it is not limited to this. The container body 10 may be configured as a box having an opening 13 without having a recess 11, for example. The container body 10 may be configured as a box having the shape of a rectangular parallelepiped or a cube, for example.

[0147] The humidity indicator unit 50 may be located on the inner surface of the front side of the container body 10, for example, as shown in Figures 10 and 11. However, it is not limited to this, and the humidity indicator unit 50 may be located on the inner surface of the side side of the container body 10, or on the inner surface of the rear side of the container body 10.

[0148] According to the third modified example of the packaging package 1 described above, the container body 10 is configured as a box having an opening 13, making it easy to stack multiple packaging packages 1. In addition, the packaging package 1 facilitates the insertion and removal of shoes S through the opening 13.

[0149] Figure 12 is a schematic external perspective view showing an example of the configuration of the disassembled packaging package 1 according to the fourth modified example of this disclosure. Figure 13 is a schematic external perspective view showing an example of the configuration of the fitted packaging package 1 of Figure 12. An example of the configuration of the packaging package 1 according to the fourth modified example will be mainly described with reference to Figures 12 and 13.

[0150] In the third modification described above, the container body 10 is described as being configured as a box having the shape of a rectangular parallelepiped or a cube, but it is not limited to this. The container body 10 may be configured with a shape having an inclined surface 15 on a part of its front side. This makes it possible for the packaging package 1 to have the front of the container body 10 configured in a shape that conforms to the shape of the shoe S contained within the packaging package 1.

[0151] Figure 14A is a schematic external perspective view showing an example of the configuration of the open state of the packaging package 1 according to the fifth modified example of this disclosure. Figure 14B is a schematic top view showing an example of the configuration of the closed state of the packaging package 1 according to the fifth modified example of this disclosure. An example of the configuration of the packaging package 1 according to the fifth modified example will be mainly described with reference to Figures 14A and 14B. In the above embodiment, the container body 10 and the lid 20 have been described as being separate from each other, but this is not limited to this. The container body 10 and the lid 20 may be permanently connected.

[0152] In this case, the lid 20 may open or close the opening 13 of the container body 10, like a door to the container body 10. The opening 13 of the container body 10 and the lid 20 may be positioned relative to the side of the shoe S. The shoe S may be inserted into and removed from the inside of the container body 10 from the side through the opening 13 when the lid 20 is lowered and open.

[0153] The width L1 of the container body 10 may be greater than or equal to the width L2 on the opening 13 side, which is the sum of the width of the opening 13 and the width of the mounting portion 30. For example, the corner of the container body 10 adjacent to the opening 13 may have an R-shape toward the inside of the container body 10 in a top view as shown in Figure 14B, and may be configured to include the mounting portion 30 inside the width L1. This makes it possible to efficiently arrange multiple packaging packages 1 in a state where adjacent pairs of packaging packages 1 are in close contact without any gaps on the left and right when stacked vertically and horizontally.

[0154] Figure 15 is an enlarged schematic diagram of a part of the configuration of the packaging package 1 according to the sixth modified example of the present disclosure. In the above embodiment, the packaging package 1 does not have any other configuration at the location where the sealing member 40 is placed on the surface of the lid 20, but is not limited thereto. The lid 20 of the packaging package 1 may further have a magnet 24 embedded within the thickness of the main body portion 22 at the location where the sealing member 40 is placed on the surface of the lid 20. The container body 10 may further have a metal member 16 such as iron embedded within the thickness of the edge portion 12 facing the sealing member 40.

[0155] As a result, the packaging package 1 can improve the airtightness inside the packaging package 1 when it is fitted. In the fitted state, the packaging package 1 can improve the tightness between the container body 10 and the lid 20 by sandwiching the sealing member 40 between the magnet 24 and the metal member 16, and the magnetic force of the magnet 24 that attracts the metal member 16.

[0158] (Manufacturing example 1: Packaging package A) DIC Dry LX-470EL (manufactured by DIC Corporation), SP-60 (manufactured by DIC Corporation), and ethyl acetate were mixed in a weight ratio of 1:1:1. This mixture was then applied to a biaxially oriented polypropylene film (manufactured by Toyobo Co., Ltd., P2161 OPP film) using a laminator, and then laminated to an unoriented polypropylene film (manufactured by Toyobo Co., Ltd., P1128 CPP film). The amount of adhesive solids applied was 3 g / m². 2 The resulting laminate film was stored at 40°C for 72 hours to obtain packaging package A. A humidity indicator (manufactured by Asei Kogyo, RH70) was attached to the unoriented polypropylene film side of the obtained packaging package A.

[0159] (Manufacturing Example 2: Packaging Package B) UV-cut ink (DIC Corporation, XS-891) was diluted with a diluent (DIC Corporation, Univia NT Reducer No. 1 K) to a viscosity of 16 seconds (25°C, Zahn Cup No. 3). The diluted UV-cut ink was printed onto a biaxially oriented polypropylene film (Toyobo Co., Ltd., P2161 OPP film, 20 μm thick) using a gravure printing press. The thickness of the UV-cut ink layer was 1 μm. The obtained film was laminated with an unoriented polypropylene film (Toyobo Co., Ltd., P1128 CPP film, 30 μm thick) using the same method as in Production Example 1 to obtain packaging package B.

[0160] (Manufacturing Example 3: Packaging Package C) Packaging package C was obtained in the same manner as in Manufacturing Example 1, except that the biaxially oriented polypropylene film was changed to a biaxially oriented polypropylene film coated with polyvinylidene chloride (manufactured by Daicel Corporation, Kenesi OP 1050, No. 20).

[0161] <Rating> The packaging was measured using the following method.

[0162] (Water vapor transmission rate) For the above-mentioned packaging packages A, B, C, and D, the water vapor transmission rate was measured using the isobaric method with a PARMATRAN3 / 33 (Mokon Corporation: water vapor transmission rate measuring device) under an atmosphere of 40°C and 90% RH. A smaller number indicates better moisture resistance. The results are shown in Table 1.

[0163] (Average thickness) The thicknesses of packaging packages A, B, C, and D were measured using a film thickness gauge. The results are shown in Table 1.

[0164] (Oxygen permeability) For the above-mentioned packaging packages A, B, C, and D, oxygen permeability was measured using an OX-TRAN2 / 22 (Mokon Co., Ltd.: oxygen permeability measuring device) in accordance with JIS-K7126 (isobaric method) under an atmosphere of 23°C and 0%RH. The results are shown in Table 1.
