MODE FOR CARRYING OUT THE INVENTION

[0014] (First Embodiment) The packaging body 10 of the first embodiment will be described with reference to Figures 1 to 4. The packaging body 10 shown in Figure 1 is configured to be able to package various contents 100. The contents 100 can be arbitrarily selected by the user. In the first example, the contents 100 are food products. Food products are, for example, fresh foods and processed foods. In the second example, the contents 100 are articles. Articles are, for example, stationery and daily necessities. In the example shown in Figure 1, the contents 100 are food products.

[0015] The main components of the packaging 10 are a base material 20 and a film 30. The base material 20 has a structure suitable for the placement of contents 100. The film 30 has a structure suitable for packaging the contents 100 placed on the base material 20. Any packaging form can be selected for the packaging 10. In the first example, it is a skin pack packaging in which the base material 20, film 30, and contents 100 are packaged in close contact by heating the film 30 with heat. In the second example, it is a vacuum pack packaging in which the air in the internal space formed by the base material 20 and film 30 is removed before packaging. In skin pack packaging, there is virtually no space formed between the part of the film 30 that is not in close contact with the contents 100 and the base material 20. In vacuum pack packaging, a small space is formed between the part of the film 30 that is not in close contact with the contents 100 and the base material 20. In the example shown in Figure 1, the packaging form of the packaging 10 is skin pack packaging. With skin pack packaging, since no internal space is formed, liquids released from the food are less likely to leak out when the contents 100 are food products. Therefore, the freshness and appearance of the food products can be maintained in a suitable state for a long period of time. Furthermore, since the contents 100 do not move relative to the base material 20, there are fewer restrictions on how the package 10 can be displayed.

[0016] The shape of the base material 20 can be arbitrarily selected according to the type and size of the contents 100. In the example shown in Figure 1, the shape of the base material 20 is rectangular, which is suitable for placing the food contents 100. The shape of the base material 20 may also be triangular, square, a polygon with pentagons or more, a circle, or an ellipse. The size of the base material 20 is set according to the contents 100. Preferably, the area of ​​the base material 20 when viewed from above is at least twice the area of ​​the contents 100 when viewed from above.

[0017] The base material 20 includes a multi-layer structure. The base material 20 shown in Figure 3 includes an innermost layer 21, a barrier layer 22, a bonding layer 23, a paper layer 24, and an outermost layer 25. Each layer constituting the base material 20 is laminated by any means. In one example, each layer constituting the base material 20 is laminated by a dry lamination process.

[0018] The innermost layer 21 is laminated to the innermost part of the base material 20, in other words, the position closest to the contents 100. Preferably, the innermost layer 21 is made of a material that has a waterproof function. This prevents moisture leaking out from the contents 100. The material constituting the innermost layer 21 includes, for example, at least one of polyethylene, polypropylene, polyester, vinyl carboxylate, and acrylic acid ester. The thickness of the innermost layer 21 is selected to be sufficient for the waterproof function. For example, the thickness of the innermost layer 21 is 55 μm.

[0019] The barrier layer 22 is laminated on the side opposite to the contents 100 relative to the innermost layer 21. Therefore, if the contents 100 contain moisture, the moisture seeping out from the contents 100 is less likely to penetrate the paper layer 24. This maintains the strength of the base material 20. Hereinafter, for any given layer, the side opposite to the contents 100 may be referred to as the outside, and the side facing the contents 100 may be referred to as the inside. The barrier layer 22 is made of a material that is excellent in at least one of gas barrier properties and moisture barrier properties. Therefore, the quality of the contents 100 is maintained well over a long period of time. In this embodiment, the barrier layer 22 is made of a material that is excellent in gas barrier properties and moisture barrier properties. The material constituting the barrier layer 22 is, for example, polyethylene terephthalate with an inorganic thin film such as aluminum oxide or silicon oxide deposited on it. The gas whose permeation is suppressed by the barrier layer 22 is, for example, oxygen. The thickness of the barrier layer 22 is selected to be sufficient for gas barrier properties and moisture barrier properties. The thickness of the barrier layer 22 is, for example, 12 μm.

[0020] The bonding layer 23 is laminated on the outside of the barrier layer 22, for example. The bonding layer 23 is made of a material that can bond the barrier layer 22 and the paper layer 24. The material that makes up the bonding layer 23 is, for example, ethylene-methacrylic acid copolymer resin (EMAA resin). The thickness of the bonding layer 23 is selected to be sufficient to bond the barrier layer 22 and the paper layer 24. The thickness of the bonding layer 23 is, for example, 20 μm.

[0021] The paper layer 24 is laminated, for example, on the outside of the bonding layer 23. The material constituting the paper layer 24 is, for example, non-recycled paper. The basis weight contributing to the thickness of the paper layer 24 can be arbitrarily selected. Preferably, the basis weight of the paper layer 24 is determined based on the relationship between the resistance of the base material 20 to warping when the base material 20 and the film 30 are bonded together, and the thickness of the packaging 10. A preferred example of the maximum basis weight of the paper layer 24 is 1000 g / m². 2 The basis weight of the 24th layer of paper is 1000 g / m². 2 The thickness of the packaging 10 will not become excessive if the following conditions are met. This reduces the cost of the packaging 10. The basis weight of the paper layer 24 is 1000 g / m². 2If the following conditions are met, a fine gap is formed that allows water vapor to pass through. A preferred minimum value for the basis weight of the paper layer 24 is 100 g / m². 2 The basis weight of the 24th layer of paper is 100 g / m². 2 In the above case, the base material 20 is less likely to warp when the base material 20 and the film 30 are joined together. An example of a preferred range for the basis weight of the paper layer 24 is 100 g / m². 2 More than ~1000g / m 2 The following is an example: For instance, the basis weight of paper layer 24 is 450 g / m². 2 That is the case.

[0022] The outermost layer 25 is laminated on the outside of the paper layer 24. The outermost layer 25 is made of a material that includes a waterproofing function. Therefore, even if condensation occurs, water is less likely to penetrate the paper layer 24. This maintains the strength of the base material 20. The materials that make up the outermost layer 25 are, for example, polyethylene, polypropylene, and polyester. The thickness of the outermost layer 25 is selected to be sufficient to prevent water from penetrating the paper layer 24. The thickness of the outermost layer 25 is, for example, 20 μm.

[0023] The film 30 comprises multiple layers. Preferably, the multiple layers are made of transparent material so that the contents 100 can be seen. The film 30 shown in Figure 4 comprises an innermost layer 31, a first adhesive layer 32, a barrier layer 33, a second adhesive layer 34, an intermediate layer 35, and an outermost layer 36. Each layer of the film 30 is laminated by any means. In one example, each layer constituting the film 30 is laminated by co-extrusion.

[0024] The innermost layer 31 is laminated on the innermost part of the film 30, in other words, in the position closest to the contents 100. When the packaging form of the package 10 is a skin pack or a vacuum pack, the portion of the innermost layer 31 facing the contents 100 is in close contact with the contents 100, as shown in Figure 2. The materials constituting the innermost layer 31 are polyethylene, polypropylene, and polyester. The thickness of the innermost layer 31 is, for example, 30 μm.

[0025] The first adhesive layer 32 is laminated, for example, on the outside relative to the innermost layer 31. The first adhesive layer 32 adheres the innermost layer 31 to the barrier layer 33. The material constituting the first adhesive layer 32 is, for example, an adhesive resin polymerized with adhesive functional groups. The thickness of the first adhesive layer 32 is selected to be suitable for bonding the innermost layer 31 to the barrier layer 33. The thickness of the first adhesive layer 32 is, for example, 5 μm.

[0026] The barrier layer 33 is laminated, for example, on the side opposite to the contents 100 relative to the first adhesive layer 32. The barrier layer 33 is preferably made of a material that is excellent in at least one of gas barrier properties, oil resistance, and moisture resistance. The material constituting the barrier layer 33 is, for example, ethylene-vinyl alcohol copolymer (EVOH). The gas whose permeation is suppressed by the barrier layer 33 is, for example, oxygen. The thickness of the barrier layer 33 is selected to be suitable for implementing at least one of gas barrier properties, oil resistance, and moisture resistance. The thickness of the barrier layer 33 is, for example, 30 μm.

[0027] The second adhesive layer 34 is laminated on the outside of the barrier layer 33. The second adhesive layer 34 adheres the barrier layer 33 to the intermediate layer 35. The material constituting the second adhesive layer 34 is, for example, an adhesive resin polymerized with adhesive functional groups. The thickness of the second adhesive layer 34 is selected to be suitable for bonding the barrier layer 33 to the intermediate layer 35. For example, the thickness of the second adhesive layer 34 is 5 μm.

[0028] The intermediate layer 35 is laminated on the outside of the second adhesive layer 34. The intermediate layer 35 is preferably made of a material that is excellent in at least one of toughness and wear resistance. The material constituting the intermediate layer 35 is, for example, polyamide. The thickness of the intermediate layer 35 is selected to be suitable for achieving at least one of toughness and wear resistance. The thickness of the intermediate layer 35 is, for example, 30 μm.

[0029] The outermost layer 36 is laminated on the outside relative to the intermediate layer 35. The outermost layer 36 is preferably made of a material that is excellent in at least one of the following: heat resistance, gas barrier properties, moisture resistance, strength, and transparency. Examples of materials that make up the outermost layer 36 are polyethylene, polypropylene, and polyester. The thickness of the outermost layer 36 is selected to be suitable for at least one of the following: heat resistance, gas barrier properties, moisture resistance, strength, and transparency. For example, the thickness of the outermost layer 36 is 50 μm.

[0030] The packaging 10 further includes a resealing means. The resealing means is a means for repackaging part or all of the contents 100 after the contents 100 have been removed from the packaging 10. An example of a resealing means is an adhesive layer 50 having adhesive properties. In one example, the thickness of the adhesive layer 50 in the lamination direction on the packaging 10 is 10 μm or more. The thickness of the adhesive layer 50 in the lamination direction is 40 μm or less. Another example of a resealing means is a zipper tape and a slider zipper.

[0031] The adhesive layer 50 adheres the base material 20 and the film 30. As shown in Figure 2, the adhesive layer 50 is configured to adhere to the innermost layer 21 of the base material 20. The adhesive layer 50 is configured to adhere to the innermost layer 31 of the film 30 when the packaging body 10 packages the contents 100. Preferably, the adhesive layer 50 is made of a material that does not come into contact with and affect the food if the contents 100 are food. Examples of effects include food spoilage, odor of the adhesive layer 50, and transfer of stickiness to the food. The adhesive layer 50 is made of at least one of the following: an acrylic adhesive made of an acrylic polymer, a urethane adhesive made of polyurethane, a silicone adhesive made of a silicone polymer, or a rubber adhesive. The adhesive layer 50 is made up of one or more layers. The adhesive strength and adhesive of each layer of the adhesive layer 50 may be the same or different. In one example, the adhesive strength between the innermost layer 31 and the adhesive layer 50 is 0.1 N / 15 mm or more. Preferably, the adhesive strength between the innermost layer 31 and the adhesive layer 50 is 1 N / 15 mm or more. The adhesive strength between the innermost layer 31 and the adhesive layer 50 is 10 N / 15 mm or less. Preferably, the adhesive strength between the innermost layer 31 and the adhesive layer 50 is 8 N / 15 mm or less. In one example, the adhesive strength between the innermost layer 31 and the adhesive layer 50 of the film 30 is 2.0 N / 15 mm. The adhesive strength between the innermost layer 31 and the adhesive layer 50 of the film 30 is weaker than the adhesive strength between the innermost layer 21 and the adhesive layer 50 of the base material 20. In one example, the adhesive strength between the innermost layer 21 and the adhesive layer 50 is 10 N / 15 mm or more. Preferably, the adhesive strength between the innermost layer 21 and the adhesive layer 50 is 15 N / 15 mm or more. The contents 100 are removed when the innermost layer 31 and the adhesive layer 50 peel off. The adhesive layer 50 is configured to maintain its adhesiveness so that it can be re-adhered to the innermost layer 31.

[0032] The operation of the packaging 10 of the first embodiment will be described with reference to Figures 2, 5, and 6. For example, the user 200 peels off the film 30 and the adhesive layer 50. The contents 100 contained in the packaging 10 are exposed through the space created between the film 30 and the adhesive layer 50. The user 200 takes out a portion of the contents 100. The contents 100 are repackaged by re-adhering the film 30 and the adhesive layer 50.

[0033] According to the packaging 10 of the first embodiment, the following further effects can be obtained. The adhesive strength between the adhesive layer 50 and the innermost layer 31 of the film 30 is weaker than the adhesive strength between the adhesive layer 50 and the innermost layer 21 of the base material 20. Therefore, the adhesive layer 50 and the film 30 can be easily peeled apart, and the contents 100 can be easily removed.

[0034] (Second Embodiment) The packaging body 10 of the second embodiment will be described with reference to Figures 7 to 9. Components common to the packaging body 10 of the first embodiment are denoted by the same reference numerals as in the packaging body 10 of the first embodiment, and redundant explanations may be omitted. The packaging body 10 of the second embodiment differs from the packaging body 10 of the first embodiment in the position of the adhesive layer 50 in the packaging body 10, the means of bonding the base material 20 and the film 30, and the method of removing the contents 100.

[0035] The base material 20 and the film 30 are joined by any means. In one example, the base material 20 and the film 30 are joined by an easy-peel structure 40. The easy-peel structure 40 is a structure in which the innermost layer 21 of the base material 20 and the innermost layer 31 of the film 30 are sealed. The innermost layer 21 is made of a material that is easy to peel when sealed with the innermost layer 31 of the film 30. The material that makes up the innermost layer 21 is, for example, an easy-peel film. The innermost layer 31 is made of a material that is easy to peel when sealed with the innermost layer 21 of the base material 20. The material that makes up the innermost layer 31 is, for example, an ionomer resin.

[0036] The easy-peel structure 40 is constructed by heating the base material 20 and film 30, which are capable of forming the easy-peel structure 40, according to heating conditions. The heating conditions include heating time and heating temperature. An example of heating time is 20 seconds. An example of heating temperature is 150 degrees. The seal strength of the easy-peel structure 40 is set to a degree that allows it to be easily peeled off by the user, but does not peel off naturally during transport and display. In one example, the seal strength of the easy-peel structure 40 is 1.0 N / 15 mm or more. When the seal strength of the easy-peel structure 40 is 1.0 N / 15 mm or more, the film 30 is less likely to peel off from the base material 20 even when standard stress is applied to the packaging 10 during transport and display. In one example, the seal strength of the easy-peel structure 40 is 5.0 N / 15 mm or less. If the seal strength of the easy-peel structure 40 is 5.0 N / 15 mm or less, the user can easily peel the film 30 from the base material 20 by applying a standard force to peel off the packaging 10. An example of a seal strength for the easy-peel structure 40 is 2.0 N / 15 mm.

[0037] The peeling type of the easy-peel structure 40 includes at least one of the cohesive peeling type, interlayer peeling type, or interfacial peeling type. With the interfacial peeling type easy-peel structure 40, when the film 30 is peeled from the base material 20, peeling marks of the film 30 are less likely to remain on the base material 20, improving the appearance of the package 10. With the cohesive peeling type easy-peel structure 40, peeling marks of the film are more likely to remain on the base material 20, which is effective in deterring tampering and alteration of the package 10.

[0038] The adhesive layer 50 is provided between multiple layers that make up the base material 20. In one example, the adhesive layer 50 is provided between the barrier layer 22 and the bonding layer 23. In another example, it is provided between the paper layer 24 and the outermost layer 25. In the following, the multiple layers of the base material 20 that are inside the adhesive layer 50 may be referred to as the first layer 20A, and the multiple layers of the base material 20 that are outside the adhesive layer 50 may be referred to as the second layer 20B. In one example, the first layer 20A includes the innermost layer 21 and the barrier layer 22. The second layer 20B includes the bonding layer 23, the paper layer 24, and the outermost layer 25. The adhesive strength between the first layer 20A and the adhesive layer 50 is, for example, 3N / 15mm. The adhesive strength between the second layer 20B and the adhesive layer 50 is, for example, 3N / 15mm. The adhesive layer 50 may be provided instead of the bonding layer 23.

[0039] The packaging 10 further comprises an opening section 60. The opening section 60 is configured for removing the contents 100 from the packaging 10. The opening section 60 is provided, for example, in a base material 20. In one example, the opening section 60 is a notch provided along the stacking direction of the base material 20. In another example, the opening section 60 is a cutout provided along the stacking direction of the base material 20. The notch is formed into a perforation, for example, by laser processing using laser irradiation or processing with a cutter. The opening section 60 includes a first opening section 61 and a second opening section 62.

[0040] The first opening portion 61 is provided in the first layer 20A. The first opening portion 61 is configured to allow the first piece P1, including the first layer 20A, to be peeled off from the base material 20. In a plan view of the base material 20 with the first piece P1 attached, the first opening portion 61 is provided on at least a portion of the first piece P1 in the circumferential direction. The first opening portion 61 is sealed from the outside by the adhesive layer 50 and the film 30 when the packaging body 10 contains the contents 100.

[0041] The second opening portion 62 is provided in the adhesive layer 50 and the second layer 20B. The second opening portion 62 is configured to allow the second piece P2, including the second layer 20B and the adhesive layer 50, to be peeled from the base material 20. In a plan view of the base material 20 with the second piece P2 attached, the second opening portion 62 is provided on at least a portion of the second piece P2 in the circumferential direction. The second opening portion 62 is provided at a different position from the first opening portion 61 in the stacking direction. The second opening portion 62 is configured to be visible when the package 10 contains its contents. The inner end of the second opening portion 62 is sealed from the outside by the first layer 20A.

[0042] In one example, the shape of the first piece P1 in plan view is circular. In another example, it is polygonal. In one example, the shape of the second piece P2 in plan view is circular. In another example, it is polygonal. Preferably, the shape of the first piece P1 and the shape of the second piece P2 are the same. Preferably, the area of ​​the first piece P1 in plan view is smaller than the area of ​​the second piece P2 in plan view. In one example, the area of ​​the first piece P1 in plan view is 0.2 to 0.5 times the area of ​​the second piece P2 in plan view. The area of ​​the first piece P1 in plan view is larger than the area of ​​the contents 100 in plan view. In one example, the area of ​​the first piece P1 in plan view is 1.1 to 1.5 times the area of ​​the contents 100 in plan view.

[0043] The operation of the packaging 10 of the second embodiment will be described with reference to Figures 8 and 9. For example, user 200 peels off the second piece P2 from the area where the second opening 62 is provided, exposing the first opening 61 and the first piece P1. The first piece P1 is peeled off from the area where the first opening 61 is provided, exposing the contents 100. A portion of the contents 100 is taken out, and the contents 100 are repackaged by reattaching the first piece P1 and the second piece P2 to the base material 20.

[0044] According to the packaging 10 of the second embodiment, the following further effects can be obtained. The first opening 61 and second opening 62 provided in the base material 20 allow the first piece P1 and the second piece P2, which constitute a part of the base material 20, to be peeled off, and a portion of the contents 100 can be taken out. The adhesive layer 50 allows the first piece P1 and the second piece P2 to be reattached to the base material 20, and the contents 100 can be repackaged.

[0045] Since the base material 20 and the film 30 are joined by an easy-peel structure 40, the contents 100 can be easily removed by peeling off the easy-peel structure 40 when there is no need to repackage the contents 100.

[0046] (Third embodiment) The packaging body 10 of the third embodiment will be described with reference to Figures 10 to 12. Components common to the packaging body 10 of the first and second embodiments are denoted by the same reference numerals, and redundant explanations may be omitted. The packaging body 10 of the third embodiment differs from the packaging body 10 of the second embodiment in that it includes a notch 70.

[0047] The packaging 10 further includes a notch 70. The notch 70 is designed to facilitate the separation of the adhesive layer 50 from the first layer 20A that constitutes the base material 20. In one example, the notch 70 is formed by cutting out a portion of the adhesive layer 50. The notch 70 creates a space S1 between the first layer 20A and the second layer 20B. The size of the space S1 is formed to be large enough for the fingertips of a user 200 to fit into. One or more notches 70 are provided on the base material 20. In the example shown in Figure 10, one notch 70 is provided on the base material 20. Preferably, the notch 70 is provided in a portion corresponding to the corner of a polygon when the base material 20 has a polygonal shape.

[0048] The operation of the packaging 10 of the third embodiment will be described with reference to Figures 11 and 12. For example, the user 200 peels off the first layer 20A and the adhesive layer 50 from the notch 70. The first opening 61 is exposed. The third piece P3 is peeled off from the portion where the first opening 61 is located, and the contents 100 are exposed. A portion of the contents 100 is taken out, and the contents 100 are repackaged by reattaching the third piece P3 to the base material 20.

[0049] According to the packaging 10 of the third embodiment, the following further effects can be obtained. The notch 70 creates a space S1. By inserting a fingertip into space S1, the user 200 can more easily peel off the adhesion between the first layer 20A and the adhesive layer 50.

[0050] (Fourth Embodiment) The packaging body 10 of the fourth embodiment will be described with reference to Figures 13 to 15. Components common to the packaging body 10 of the first to third embodiments are denoted by the same reference numerals, and redundant explanations may be omitted. The packaging body 10 of the fourth embodiment differs from the packaging body 10 of the first to third embodiments in the configuration of the film 30.

[0051] In the fourth embodiment of the packaging 10, the adhesive layer 50 is laminated at any location on the film 30. In the first example, the adhesive layer 50 is laminated inside the innermost layer 31 of the film 30. In the second example, the adhesive layer 50 is laminated between the innermost layer 31 and the barrier layer 33. In the third example, it is laminated between the barrier layer 33 and the intermediate layer 35. Figure 13 shows the first example of the packaging 10. In the first example of the packaging 10, the contents 100 are placed on the innermost layer 21 of the base material 20 and packaged by being covered with the adhesive layer 50 of the film 30. When the adhesive layer 50 is provided at the location of the second or third example, the film 30 further comprises the configuration of an opening portion 60.

[0052] The adhesive layer 50 is provided with a notch 51. The notch 51 is configured to allow the contents 100 to be removed. The notch 51 separates the adhesive layer 50 into a first adhesive layer 50A and a second adhesive layer 50B. In this embodiment, the first adhesive layer 50A adheres to the innermost layer 31 of the film 30. The second adhesive layer 50B adheres to the innermost layer 21 of the base material 20. The notch 51 is formed, for example, by laser processing using laser irradiation or by processing with a cutter.

[0053] The operation of the fourth embodiment of the packaging 10 will be described with reference to Figures 14 and 15. For example, user 200 separates the adhesive layer 50 into a first adhesive layer 50A and a second adhesive layer 50B from the cut portion 51. When the cut in the adhesive layer 50 by the cut portion 51 reaches the contents 100, the contents 100 are exposed to the outside. A portion of the contents 100 is removed, and the contents 100 are repackaged by the first adhesive layer 50A and the second adhesive layer 50B adhering to each other again.

[0054] (modified version) The descriptions of each embodiment are illustrative of possible forms of packaging according to the present invention and are not intended to limit those forms. In addition to each embodiment, packaging according to the present invention may take the form of, for example, variations of each embodiment shown below, and combinations of at least two non-inconsistent variations.

[0055] The innermost layer 21 and innermost layer 31 in the packaging 10 of the first embodiment may be configured to be joined by an easy-peel structure 40. In this case, the base material 20 and the film 30 are joined by the easy-peel structure 40 and the adhesive layer 50.

[0056] In the packaging 10 of the second embodiment, the first opening portion 61 may extend to the adhesive layer 50. The first opening portion 61 is composed of the first layer 20A and the adhesive layer 50 in the base material 20. The second opening portion 62 is composed of the second layer 20B.
