Abstract
Description
[Technical Field]
[0001] This disclosure relates to packaging materials for packaging articles. [Background technology]
[0002] Various types of packaging materials have been known for a long time. Japanese Utility Model Publication No. 60-18365 describes a packaging material as a form of product packaging. The packaging material consists of a transparent plastic film that wraps the entire group of products, and kraft paper that is attached to the film. The group of products is housed inside a box-shaped kraft paper, and the film wraps the entire product by covering both the kraft paper and the group of products.
[0003] Japanese Utility Model Publication No. 1-38054 describes a packaging configuration comprising a box-shaped receiving plate on which the bottom of a group of goods rests, and a packaging film that wraps the receiving plate and the group of goods. In this packaging configuration, the group of goods is piled up on the receiving plate, and the packaging film wraps around the receiving plate and the group of goods in a wrap-around manner. [Prior art documents] [Patent Documents]
[0004] [Patent Document 1] Official Gazette No. 60-18365 [Patent Document 2] Publication No. 1-38054 [Overview of the Initiative] [Problems that the invention aims to solve]
[0005] In the aforementioned packaging materials and forms, a box-shaped kraft paper or receiving board is wrapped in film. However, especially in recent years, there has been a demand to reduce the amount of resin materials such as film used for environmental reasons. Thus, there is a need for environmentally friendly packaging materials.
[0006] This disclosure aims to provide environmentally friendly packaging materials. [Means for solving the problem]
[0007] The packaging material relating to this disclosure comprises (1) a packaging material for packaging an article, comprising a tray on which the article is placed, and wrapping paper for packaging the article and at least a portion of the tray.
[0008] In this packaging material, items are placed on a tray. The items, and at least a portion of the tray, are wrapped in wrapping paper. Therefore, since the items placed on the tray are wrapped in wrapping paper, the use of resin materials such as film can be eliminated. As a result, it can be an environmentally friendly packaging material. In addition, by providing wrapping paper to wrap the items, it can be opened more easily than with cardboard boxes, etc. That is, the wrapping paper can be cut with scissors to open it, so the packaging material can be opened easily.
[0009] (2) In (1) above, the wrapping paper may have a tearing section for tearing the wrapping paper. In this case, the wrapping paper can be easily cut along the tearing section, so the packaging material can be easily opened without scissors or the like.
[0010] (3) In (1) or (2) above, the tray may have a bottom on which an article is placed and a plurality of sides that rise from the outer edge of the bottom. A pair of wrapping papers may be bonded together on the outside of the side of the tray on which the article is placed, and the height of the side located inside the area where the wrapping papers are bonded together may be higher than the height of the other side. In this case, a pair of wrapping papers are bonded together on the outside of the side of the tray. The height of the side located inside this bonding area is higher than the height of the other side. Therefore, when bonding a pair of wrapping papers, the side is located inside the bonding area, making bonding easier compared to when the article is located inside the bonding area. That is, when the bonding machine is pressed against the wrapping papers to bond them, the side, not the article, repels the bonding machine, making bonding by the bonding machine easier.
[0011] (4) In any of (1) to (3) above, the article may have a curved surface facing the side of the tray. Even when an article with a curved surface is packaged, the packaging material can be easily opened.
[0012] (5) In any of the above (1) to (4), the wrapping paper may be kraft paper. In this case, the wrapping paper can be made stronger compared to other types of paper.
[0013] (6) In any of the above (1) to (4), the wrapping paper may be made of corrugated cardboard liner. In this case, the wrapping paper can be recycled because it is made of corrugated cardboard liner. Therefore, the recyclability of the wrapping paper can be increased, making it a more environmentally friendly packaging material.
[0014] (7) In any of (1) to (6) above, the packaging material may include shock-absorbing material placed on the opposite side of the tray of the article, with the shock-absorbing material interposed between the article and the wrapping paper. In this case, the article is sandwiched between the tray and the shock-absorbing material, and the shock-absorbing material is then wrapped by the wrapping paper. Therefore, the wrapping paper can be made more tear-resistant, and damage to the article can be prevented more reliably.
[0015] (8) In the above (7), the shock-absorbing material may have a plate-like portion that is placed on the article and a bent portion that is bent from the outer edge of the plate-like portion and faces the article. In this case, the plate-like portion is placed on the article and the bent portion faces the side of the article. Therefore, a part of the article can be covered from above and from the side by the shock-absorbing material, so that damage to the article can be prevented more reliably.
[0016] (9) In (7) or (8) above, the material of the shock-absorbing material may be the same as the material of the tray. In this case, since the material of the shock-absorbing material is the same as the material of the tray, the preparation of the shock-absorbing material can be made easy, and the increase in the cost of the shock-absorbing material can be suppressed. [Effects of the Invention]
[0017] According to the present disclosure, an environmentally considerate packaging material can be provided.

Modes for Carrying Out the Invention
[0019] The embodiments of the packaging material relating to this disclosure will be described below with reference to the drawings. In the description of the drawings, the same or equivalent elements will be denoted by the same reference numeral, and redundant explanations will be omitted as appropriate. In addition, for the sake of ease of understanding, some parts of the drawings may be simplified or exaggerated, and the dimensional ratios, etc., are not limited to those shown in the drawings.
[0020] The packaging material according to this embodiment is used to package articles. In this disclosure, "article" refers to an object, such as a product, display item, or food and beverage. "Product" refers to an item sold, such as a novelty item or toy. "Display item" refers to a display sample or product sample. "Food and beverage" refers to food or beverage, such as a beverage can, bottle, or PET bottle. The following example describes an example where the article is a beverage can.
[0021] The articles are placed on a tray. In this disclosure, “tray” refers to a box-shaped tray or a plate-shaped tray on which the articles are placed. The “tray” only needs to have sufficient strength to hold the articles, and the material of the tray is not particularly limited. The articles are wrapped in wrapping paper. “Wrapping paper” refers to the paper used for wrapping.
[0022] In this disclosure, "paper" refers to a material made by intertwining fibers, raking them together to form a thin film, and then drying it. In other words, "paper" is a material made by intertwining fibers to form a sheet, and includes materials in which the fibers are bonded together. Furthermore, "paper" may be made from pulp (wood fibers), synthetic paper containing synthetic resin, or synthetic fiber paper manufactured from synthetic fibers cut to a predetermined length. In this embodiment, "paper" is a concept that does not include resin films.
[0023] Figures 1(a) and 1(b) are perspective views showing a packaging material 1 in which an article is wrapped by wrapping paper 2. Figure 2 is a perspective view showing the tray 3 and article C of the packaging material 1 with the wrapping paper 2 removed. As shown in Figures 1(a), 1(b), and 2, the packaging material 1 comprises a tray 3 on which the article C is placed, and wrapping paper 2 that wraps the article C and the tray 3.
[0024] For example, tray 3 is made of paper. In this case, tray 3 can be made environmentally friendly. As an example, tray 3 is made of corrugated cardboard (e.g., microflute). The thickness of tray 3 is, for example, 0.5 mm or more and 2.0 mm or less (2.0 mm as an example). As an example, tray 3 has a box shape. Tray 3 has a rectangular box shape with an opening 3f facing vertically upward.
[0025] Tray 3 has a plurality of long sides 3b extending in a first direction D1, a plurality of first short sides 3c extending in a second direction D2 intersecting the first direction D1, and a plurality of second short sides 3d extending in a third direction D3 intersecting both the first direction D1 and the second direction D2. The first direction D1 corresponds to the longitudinal direction of tray 3, and the second direction D2 corresponds to the width direction of tray 3. When an item C is placed on it, the third direction D3 corresponds to the height direction of tray 3.
[0026] Tray 3 has a bottom portion 3A defined by a long side 3b and a first short side 3c, a side portion 3B defined by a long side 3b and a second short side 3d, and a side portion 3C defined by a first short side 3c and a second short side 3d. For example, tray 3 has a bottom portion 3A facing a third direction D3, a pair of side portions 3B aligned along a second direction D2, and a pair of side portions 3C aligned along a first direction D1. As an example, the bottom portion 3A, side portions 3B, and side portions 3C are rectangular (or square).
[0027] The bottom 3A is oriented vertically downward. For example, multiple items C are placed above the bottom 3A. Each side 3B extends in the first direction D1 and the third direction D3 at each end of the second direction D2 in the tray 3. Each side 3C extends in the second direction D2 and the third direction D3 at each end of the first direction D1 in the tray 3.
[0028] For example, the height (length to the third direction D3) of a pair of side sections 3C aligned along the first direction D1 is the same. The adhesive points 2b where the pair of wrapping papers 2 meet are located on the outside of the side sections 3C when viewed from the third direction D3. As an example, curved sections 3h are formed at the two vertically upward corners of the four corners of the side section 3C.
[0029] For example, the side portion 3B has a bent portion 3g that is bent from the end in the first direction D1 in the second direction D2, and the side portion 3C, which is bent in the third direction D3, is adhesively fixed to the outer surface of the bent portion 3g. However, the tray 3 may not have a bent portion 3g, and the structure of the tray 3 is not limited to the above example.
[0030] In this embodiment, article C is a beverage can. However, article C may be, for example, a food or beverage container other than a beverage can. For example, article C has a top surface C1 facing a third direction D3 and a side surface C2 extending vertically downward from the outer edge of the top surface C1. As an example, the top surface C1 is circular in shape, and the side surface C2 is cylindrical in shape.
[0031] Item C has a curved surface C3 on its side portion C2 that is oriented in a first direction D1 and a second direction D2. For example, multiple items C are arranged in tray 3 in both the first direction D1 and the second direction D2. As an example, in tray 3, six items C are arranged along the first direction D1 and four items C are arranged along the second direction D2.
[0032] The tray 3 and article C, configured as described above, are wrapped in wrapping paper 2. In the examples shown in Figures 1(a) and 1(b), the wrapping paper 2 wraps the entire tray 3 and article C. However, the wrapping paper 2 may only wrap article C and a part of the tray 3 (for example, only the top of the tray 3). The wrapping paper 2 is manufactured, for example, by bonding plant fibers. The wrapping paper 2 is, for example, kraft paper or corrugated cardboard liner. The wrapping paper 2 may be Western-style paper or Japanese-style paper. The wrapping paper 2 may be unbleached wrapping paper or bleached wrapping paper.
[0033] Unbleached wrapping paper may be heavy-duty kraft paper, other double-sided kraft paper, or other unbleached wrapping paper. Other double-sided kraft paper may be general double-sided kraft paper or special double-sided kraft paper, and other bleached wrapping paper may be ribbed kraft paper, single-sided gloss kraft paper, or other unbleached wrapping paper.
[0034] The bleached wrapping paper may be pure white roll, bleached kraft paper, or other bleached wrapping paper. The bleached kraft paper may be double-sided bleached kraft paper, or single-sided glossy (single-sided glossy bleached) kraft paper. The other bleached wrapping paper may be thin imitation paper. However, the type of wrapping paper 2 may be other than those mentioned above, for example, cardboard, coated paper, fine paper, matte paper, art post paper, matte post paper, Bristol board, or thin paper, and is not particularly limited.
[0035] The basis weight of wrapping paper 2 is, for example, 50 g / m². 2 The above and 200g / m 2 The following applies: The basis weight of wrapping paper 2 is 50 g / m². 2 As a result of the above, the thickness of the wrapping paper 2 can be set to an appropriate thickness. The basis weight of the wrapping paper 2 is 200 g / m². 2 The following conditions allow for a wrapping paper 2 that is not too thick, making it easy to fold and bend the wrapping paper 2. The basis weight of the wrapping paper 2 is 60 g / m². 2 More than 70g / m 2 or more, or 100g / m² 2It may be as described above. Also, the basis weight of the wrapping paper 2 is 180 g / m 2 or less, 160 g / m 2 or less, 150 g / m 2 or less or 120 g / m 2 or less. For example, the basis weight of the wrapping paper 2 is preferably 180 g / m 2 or less. In this case, it is possible to suppress the wrapping paper 2 from becoming too thick and difficult to fold. However, the basis weight of the wrapping paper 2 can be appropriately changed without being limited to the above-described respective values.
[0036] The wrapping paper 2 has a first extending portion 2c extending in the first direction D1 and the second direction D2 when wrapping the article C and the tray 3, and a second extending portion 2d extending in the first direction D1 and the third direction D3. The wrapping paper 2 has a first bending portion 2f bent from the end portion of the second extending portion 2d in the first direction D1 toward the second direction D2, and a second bending portion 2g bent from the end portion of the first extending portion 2c in the first direction D1 toward the third direction D3.
[0037] The wrapping paper 2 has, for example, a pair of first extending portions 2c arranged along the third direction D3 and a pair of second extending portions 2d arranged along the second direction D2. Of the pair of first extending portions 2c, the first extending portion 2c located vertically above covers the article C, and the first extending portion 2c located vertically below covers the bottom 3A of the tray 3. Each of the pair of second extending portions 2d covers the side surface portion C2 of the article C and each side portion 3B of the tray 3.
[0038] The wrapping paper 2 has, for example, a pair of first bending portions 2f arranged along the second direction D2 and a pair of second bending portions 2g arranged along the third direction D3. The location where one of the pair of second bending portions 2g is adhered to the other is the adhesion location 2b. The side portion 3C of the tray 3 is located inside the pair of second bending portions 2g when viewed along the third direction D3.
[0039] As an example, the second folded portion 2g has a trapezoidal shape with an upper and lower base extending along the second direction D2. The length of the second folded portion 2g in the second direction D2 decreases as it moves towards the center of the third direction D3 of the packaging material 1. As a result, the shape of the adhesive area 2b where the pair of second folded portions 2g overlap is hexagonal. For example, the inner surface of one second folded portion 2g is adhered to the outer surface of the other second folded portion 2g. As an example, the inner surface of the upper second folded portion 2g is adhered to the outer surface of the lower second folded portion 2g.
[0040] The packaging of the article C and tray 3 with wrapping paper 2 is carried out, for example, by caramel packaging. The bonding of the pair of second folded portions 2g is carried out, for example, by an adhesive machine. For example, the adhesive machine covers the tray 3 and article C, which are conveyed along the second direction D2, with the wrapping paper 2 on the side facing the second direction D2 and the top and bottom faces facing the third direction D3.
[0041] Subsequently, the adhesive machine folds the end of the wrapping paper 2 in the first direction D1 in the second direction D2 to form a first folded portion 2f and a second folded portion 2g, and applies adhesive to the outer surface of one of the second folded portions 2g and presses the other second folded portion 2g against that outer surface to form an adhesive area 2b. The adhesive machine may also form the adhesive area 2b by hot melt adhesive or part coat adhesive, and the method of adhesive fixing of the wrapping paper 2 is not particularly limited.
[0042] Next, the effects and advantages obtained from the packaging material 1 according to this embodiment will be described. In the packaging material 1, an article C is placed on a tray 3. At least a part of the article C and the tray 3 are wrapped with wrapping paper 2. Therefore, since the article C placed on the tray 3 is wrapped with wrapping paper 2, the use of resin materials such as film can be eliminated. As a result, the packaging material 1 can be made environmentally friendly.
[0043] In this embodiment, by packaging the article C and tray 3 with wrapping paper 2, the amount of paper used can be reduced compared to conventional corrugated cardboard boxes. Therefore, it contributes to further resource conservation. In addition, by providing wrapping paper 2 to wrap the article C, it can be opened more easily than with corrugated cardboard, etc. That is, the wrapping paper 2 can be cut with scissors to open it, so the packaging material 1 can be opened easily. Furthermore, while packaging materials made of corrugated cardboard can be difficult to dispose of due to their thickness, the packaging material 1 in this embodiment can be easily disposed of by simply tearing the thin wrapping paper 2.
[0044] Furthermore, some packaging materials made of cardboard have a zipper line (cutting line) and can be torn along the zipper line. However, with this type of packaging material, the torn edges remain jagged (for example, at the upper edge of tray 3), which is a problem because the packaging material does not look good after being torn. In contrast, with packaging material 1 in which tray 3 is wrapped in wrapping paper 2, the shape of tray 3 can be made without jagged edges (for example, the upper edges of sides 3B and 3C are smooth), so the appearance of tray 3 after opening can be improved.
[0045] As described above, the tray 3 may have a bottom 3A on which the article C is placed, and a plurality of side parts 3B, 3C that rise from the outer edge of the bottom 3A. A pair of wrapping papers 2 (second folded portion 2g) are bonded together on the outside of the side part 3C of the tray 3 on which the article C is placed, and the height of the side part 3C located inside the bonding area 2b where the wrapping papers 2 are bonded together may be higher than the height of the other side parts 3B.
[0046] In this case, the pair of wrapping papers 2 are bonded together on the outside of the side portion 3C of the tray 3. The height of the side portion 3C located inside the bonding area 2b is higher than the height of the other side portions 3B. Therefore, when bonding the pair of wrapping papers 2, the side portion 3C is located inside the bonding area 2b, making bonding easier compared to when the item C is located inside the bonding area 2b. That is, when the bonding machine is pressed against the wrapping papers 2 to bond them, the side portion 3C, not the item C, repels the bonding machine, making bonding by the bonding machine easier. On the other hand, the side portion 3B is lower than the side portion 3C, and the lower it is, the more desirable it is from the viewpoint of reducing material usage. Alternatively, a tray without side portions 3B (a tray that exhibits a U-shape when viewed along the second direction D2) may also be used.
[0047] As mentioned above, the article C may have a curved surface C3 that faces the side 3C of the tray 3. Even when packaging an article C having a curved surface C3, the packaging material 1 can be easily opened.
[0048] The wrapping paper 2 may also be kraft paper. In this case, the wrapping paper 2 can be made stronger compared to other types of paper.
[0049] The wrapping paper 2 may be made of corrugated cardboard liner. In this case, because the wrapping paper 2 is made of corrugated cardboard liner, the wrapping paper 2 can be recycled together with the tray 3. Therefore, the recyclability of the wrapping paper 2 can be increased, resulting in a more environmentally friendly packaging material 1.
[0050] The following describes various modifications of the packaging material relating to this disclosure. Note that this disclosure is not limited to the modifications described below. Furthermore, some components of the packaging material relating to the modifications described later are the same as some components of packaging material 1 described above. Therefore, in the following, descriptions that overlap with those of packaging material 1 will be appropriately omitted and denoted by the same reference numerals.
[0051] (First variation) As shown in Figures 3(a) and 3(b), the packaging material 11 according to the first modified example has a wrapping paper 12 that has a different packaging form from the wrapping paper 2. For example, the wrapping paper 12 is made of Lamina®. In this case, the wrapping paper 12 is made of heat-sealable paper. However, the wrapping paper 12 may be made of paper that is thicker than Lamina.
[0052] The wrapping paper 12 wraps the article C and tray 3 in a gusset-type packaging configuration. The wrapping paper 12 has, for example, a first extending portion 12b extending in the first direction D1 and the second direction D2, a second extending portion 12c extending in the first direction D1 and the third direction D3, and gusset portions 12d located at each end of the first direction D1.
[0053] The gusset portion 12d has a first bent portion 12f that bends in the second direction D2 from the end of the second extended portion 12c in the first direction D1, and a second bent portion 12g that bends in the third direction D3 from the end of the first extended portion 12b in the first direction D1. The gusset portion 12d has a pair of second bent portions 12g aligned along the third direction D3, and the pair of second bent portions 12g are joined to each other while protruding in the first direction D1. In the packaging material 11 equipped with the first modified packaging paper 12, the use of resin materials such as film is unnecessary, and the same effects and advantages as the packaging material 1 described above can be obtained.
[0054] (Second variation) As shown in Figures 4(a) and 4(b), the packaging material 21 according to the second modified example has a packaging paper 22 which has a different packaging form from the packaging paper 12. The packaging paper 22 has a first extended portion 12b, a second extended portion 12c, and a folded portion 22d of the gusset portion, and the structure of the folded portion 22d is different from the structure of the gusset portion 12d.
[0055] The wrapping paper 22 has, for example, folded portions 22d on both sides in a first direction D1. The folded portion 22d has a first folded portion 12f and a second folded portion 22g which is folded in a third direction D3 from the end of the first extended portion 12b in the first direction D1. The folded portion 22d has a pair of second folded portions 22g aligned along the third direction D3, with one of the pair of second folded portions 22g being attached to the other.
[0056] For example, one second folded portion 22g protrudes (slightly) more in the first direction D1 than the other second folded portion 22g. In summary, in the packaging material 21, the folded portion 22d is formed at the end in the first direction D1, making it easier to handle when manually packaging the bagged product compared to the packaging material 11 described above. Furthermore, in the packaging material 21, it is possible to wrap the entire article C and tray 3 with the wrapping paper 22, so thin paper can be used as the wrapping paper 22. Therefore, the same effects and advantages as the packaging material 1 described above can be obtained.
[0057] (Third variation) As shown in Figures 5(a) and 5(b), the packaging material 31 according to the third modified example comprises a packaging paper 32 having a different shape from the packaging paper 2 described above. The packaging paper 32 has an opening 32b at its end in the first direction D1 through which the article C is exposed. The packaging paper 32 has a first extending portion 32c extending in the first direction D1 and the second direction D2, a second extending portion 32d extending in the first direction D1 and the third direction D3, and an opening forming portion 32f that forms the opening 32b at its end in the first direction D1.
[0058] The opening-forming portion 32f has a first bent portion 32g bent in the third direction D3 from each of a pair of first extended portions 32c aligned along the third direction D3, and a second bent portion 32h bent in the second direction D2 from each of a pair of second extended portions 32d aligned along the second direction D2. The opening-forming portion 32f has a pair of first bent portions 32g aligned along the third direction D3 and a pair of second bent portions 32h aligned along the second direction D2, and an opening 32b is formed between the pair of first bent portions 32g and between the pair of second bent portions 32h.
[0059] For example, each first bent portion 32g is attached to each of the ends of the second bent portion 32h in the third direction D3. Each first bent portion 32g attached to the second bent portion 32h has a rectangular shape with a long side extending along the second direction D2 and a short side extending along the third direction D3.
[0060] The opening 32b has a rectangular shape, for example, with a longer side extending along the second direction D2 and a shorter side extending along the third direction D3. Parts of a plurality of articles C and a portion of the tray 3 are exposed in the opening 32b. However, the example is not limited to this, and only parts of the plurality of articles C or only parts of the tray 3 may be exposed in the opening 32b.
[0061] In the packaging material 31 configured as described above, the wrapping paper 32 encloses the article C and the tray 3, thus providing the same effects as previously described. Furthermore, the wrapping paper 32 has an opening 32b. Therefore, the packaging material 31 can further reduce the amount of paper used compared to packaging materials with wrapping paper that does not have an opening 32b. For example, since the article C is exposed through the opening 32b, the condition of the article C can be visually inspected from outside the packaging material 31.
[0062] (Fourth variation) As shown in Figures 6(a) and 6(b), the packaging material 41 according to the fourth modified example includes a wrapping paper 42 that forms an opening 42b. The wrapping paper 42 has a first extended portion 32c, a second extended portion 32d, and an opening-forming portion 42f that is different from the opening-forming portion 32f. The opening-forming portion 42f has a pair of first folded portions 42g aligned along the third direction D3, and a second folded portion 42h folded from the first folded portions 42g in the first direction D1.
[0063] An opening 42b is formed between a pair of first folded portions 42g, and the opening 42b extends from one end to the other in the second direction D2 of the wrapping paper 42. The wrapping paper 42 has a pair of second folded portions 42h aligned along the second direction D2. Each second folded portion 42h is folded in the first direction D1 and adhered to each second extending portion 32d.
[0064] As described above, since an opening 42b is formed in the packaging material 41, the same effects and advantages as those of the packaging material 31 can be obtained. Furthermore, in the packaging material 41, the second folded portion 42h that forms the opening 42b is folded into the second extended portion 32d, which is the long side surface, and adhered to the second extended portion 32d, so the adhesion area of the second folded portion 42h to the second extended portion 32d can be made larger than if it were folded inward.
[0065] (Fifth variation) As shown in Figures 7(a) and 7(b), the packaging material 51 according to the fifth modified example comprises a wrapping paper 52 with a different packaging form. The wrapping paper 52 packages the article C and tray 3 by fin seal packaging. The wrapping paper 52 comprises a first extended portion 32c, a second extended portion 32d, and a sealing portion 52b located at the end in the first direction D1.
[0066] The sealing portion 52b has a first bent portion 52c which is bent in a third direction D3 from the end of the first extending portion 32c in a first direction D1, and a second bent portion 52d which is bent in a second direction D2 from the end of the second extending portion 32d in a first direction D1. The sealing portion 52b has a pair of first bent portions 52c which are aligned along the third direction D3, and a pair of second bent portions 52d which are aligned along the second direction D2.
[0067] Each of the pair of second folded portions 52d is, for example, bonded to each first folded portion 52c. The length of each second folded portion 52d in the third direction D3 decreases as it moves towards the center in the second direction D2. As an example, each second folded portion 52d has a triangular shape. In the above packaging material 51 equipped with wrapping paper 52 for packaging article C and tray 3 by FinSeal packaging, the sealing performance can be enhanced and the intrusion of foreign matter can be more reliably suppressed.
[0068] (Sixth variation) As shown in Figures 8(a) and 8(b), in the packaging material 61 according to the sixth modified example, the packaging paper 62 has a pair of first extending portions 62c facing vertically upward, a second extending portion 62f facing a second direction D2, a third extending portion 62h facing vertically downward, and a sealing portion 62g located at the end in the first direction D1. The sealing portion 62g has a first folded portion 62j folded from the first extending portion 62c in the third direction D3, and a second folded portion 62k folded from the third extending portion 62h in the third direction D3. In the sealing portion 62g, the first folded portion 62j is attached to the second folded portion 62k.
[0069] The wrapping paper 62 has a tear portion 62b for tearing the wrapping paper 62. For example, the tear portion 62b is a portion intended to be torn located between a pair of first extending portions 62c aligned along a second direction D2. Because the tear portion 62b is a portion intended to be torn formed in the wrapping paper 62, it can be a more environmentally friendly tear compared to when the tear portion is tape or the like. The tear portion 62b is provided in the central part of the wrapping paper 62 in the second direction D2.
[0070] For example, the broken portion 62b includes a first portion 62p formed on the first bent portion 62j and a second portion 62q located between a pair of first extended portions 62c, with the first portion 62p and the second portion 62q being continuous with each other. The broken portion 62b has a finger rest portion 62r at the lower end of the first portion 62p formed on the first bent portion 62j. The finger rest portion 62r has notches at both ends in the width direction, making it easy to grasp with the fingers.
[0071] By pinching the finger grip portion 62r with your fingers and pulling it up, you can peel off the tear portion 62b and tear the wrapping paper 62. An example of the tear portion 62b has been described above. In this packaging material 61, the wrapping paper 62 has a tear portion 62b for tearing the wrapping paper 62. In this case, the wrapping paper 62 can be easily cut along the tear portion 62b, so the packaging material 61 can be easily opened without scissors or the like.
[0072] (Seventh variation) As shown in Figures 9(a) and 9(b), the packaging material 71 according to the seventh modified example has a different location for the break portion 72b compared to the packaging material 61 according to the sixth modified example. Specifically, the packaging material 71 has a break portion 72b located at the end of the wrapping paper 72 in the second direction D2 (for example, the right end). With this packaging material 71, the wrapping paper 72 can be easily broken by the break portion 72b, thus achieving the same effect as the packaging material 61 described above. Furthermore, because the break portion 72b in the packaging material 71 is located at the end in the second direction D2, the design of the packaging material 71 can be further improved.
[0073] (Variation 8) As shown in Figures 10(a) and 10(b), in the eighth modified example of packaging material 81, the packaging paper 82 comprises a first extended portion 32c, a second extended portion 32d, a sealing portion 82b located at the end in the first direction D1, and a break portion 82c provided in the sealing portion 82b. The break portion 82c is provided, for example, in the center in the third direction D3.
[0074] In the sealing portion 82b, as described above, a pair of second bent portions 82f, aligned along the second direction D2, are attached to a pair of first bent portions 82d, aligned along the third direction D3. The broken portion 82c includes a first portion 82g located on one of the pair of second bent portions 82f (the right side in the example of Figure 10(a)) and a second portion 82h extending along the first direction D1 in the second extending portion 32d.
[0075] The first portion 82g and the second portion 82h are continuous with each other. A finger grip portion 82j is provided at the central end of the first portion 82g in the second direction D2, and the wrapping paper 82 can be torn by pinching and pulling the finger grip portion 82j. As described above, since a tear portion 82c is formed on the side of the packaging material 81, the wrapping paper 82 can be easily torn along the tear portion 82c formed on the side of the packaging material 81. As described above, the position, shape, and size of the tear portion that tears the wrapping paper can be changed as appropriate.
[0076] Next, the packaging material according to the ninth modified example will be described with reference to Figure 12. The packaging material according to the ninth modified example comprises the wrapping paper 2 mentioned above, a tray 103, and shock-absorbing material 104. Figure 12 shows the packaging material according to the ninth modified example with the wrapping paper 2 removed, illustrating an example in which 24 items (4 x 6) of article C are packaged. For example, the material of the tray 103 is the same as the material of the tray 3 mentioned above, and is paper as one example.
[0077] Tray 103 has multiple long sides 103b extending in the first direction D1, multiple first short sides 103c extending in the second direction D2, and multiple second short sides 103d extending in the third direction D3. Tray 103 differs from tray 3 in that its height (length in the third direction D3) is lower (smaller) than that of tray 3 described above.
[0078] The tray 103 has a side portion 103B defined by a long side 103b and a second short side 103d, and a side portion 103C defined by a first short side 103c and a second short side 103d. For example, the tray 103 has a bottom portion facing a third direction D3, a pair of side portions 103B aligned along a second direction D2, and a pair of side portions 103C aligned along a first direction D1. Multiple articles C are placed on the bottom portion of the tray 103. As an example, curved portions 103h are formed at the two upper corners of the four corners of the side portion 103C. Similar curved portions are formed at the two upper corners of the four corners of the side portion 103B.
[0079] For example, the shock-absorbing material 104 is made of paper. For example, the shock-absorbing material 4 may be made of corrugated cardboard (e.g., microflute). For example, the material of the shock-absorbing material 104 is the same as the material of the tray 103. The thickness of the shock-absorbing material 104 is, for example, 0.5 mm or more and 3.0 mm or less (2.0 mm as an example). The shock-absorbing material 104 is, for example, box-shaped. For example, the shock-absorbing material 104 is a rectangular box shape with an opening facing vertically downward.
[0080] The shock-absorbing material 104 has a plurality of long sides 104b extending in a first direction D1 and a plurality of short sides 104c extending in a second direction D2. The shock-absorbing material 104 has a plate-like portion 104A defined by the long sides 104b and the short sides 104c, and a bent portion 104C that is bent from the outer edge of the plate-like portion 104A and faces the side surface of the article C.
[0081] For example, the plate-like portion 104A is rectangular in shape. The plate-like portion 104A is oriented vertically upward. The plate-like portion 104A is placed on the top surface of the article C. For example, the bent portion 104C may be the part that is bent downward from the end of the plate-like portion 104A in the first direction D1. Alternatively, the bent portion may be the part that is bent downward from the end of the plate-like portion 104A in the second direction D2.
[0082] For example, the height of the folded portion 104C is greater than the height of the tray 103 (side portion 103C). In this case, the top surface of the item C can be protected more reliably. However, the height of the folded portion 104C may be the same as the height of the tray 103, or it may be less than the height of the tray 103. As an example, the folded portion 104C has a rectangular shape. Curved portions 104h may be formed at the two lower corners of the four corners of the folded portion 104C.
[0083] As described above, the packaging material according to the ninth modification includes an impact-absorbing material 104 placed on the opposite side of the tray 103 of the article C, with the impact-absorbing material 104 interposed between the article C and the wrapping paper 2. That is, by covering the impact-absorbing material 104 with the wrapping paper 2, the impact-absorbing material 104 is positioned between the article C and the wrapping paper 2. Therefore, the impact-absorbing material 104 is wrapped by the wrapping paper 2 with the article C sandwiched between the tray 103 and the impact-absorbing material 104. Thus, the wrapping paper 2 can be made more resistant to tearing, and damage to the article C can be prevented more reliably.
[0084] In particular, in the ninth modification, the tray 103 on which the item C is placed, and the shock-absorbing material 104 placed on the item C, are wrapped in wrapping paper 2, making it difficult for the item C to come into contact with the wrapping paper 2. Therefore, it is possible to more reliably prevent situations such as the item C coming into contact with the wrapping paper 2 during transport and the wrapping paper 2 tearing.
[0085] The shock-absorbing material 104 has a plate-like portion 104A that rests on the article C, and a bent portion 104C that is bent from the outer edge of the plate-like portion 104A and faces the article C. Therefore, the plate-like portion 104A rests on the article C, and the bent portion 104C faces the side surface of the article C. Consequently, the shock-absorbing material 104 can cover a part of the article C from above and from the side, thus more reliably preventing damage to the article C.
[0086] The material of the shock-absorbing material 104 is, for example, the same as the material of the tray 103. In this case, since the material of the shock-absorbing material 104 is the same as the material of the tray 103, the preparation of the shock-absorbing material 104 can be made easy, and the increase in the cost of the shock-absorbing material 104 can be suppressed.
[0087] The tray 103 has, for example, two curved portions 103h located above the side portion 103C. In this case, when the tray 103 is wrapped with the wrapping paper 2, the wrapping paper 2 can be made more resistant to tearing. The shock-absorbing material 104 has, for example, two curved portions 104h located below the folded portion 104C. In this case, when the shock-absorbing material 104 is wrapped with the wrapping paper 2, the wrapping paper 2 can be made more resistant to tearing.
[0088] The packaging material relating to the ninth modified example has been described above. In the ninth modified example, for example, similar to the folded portion 3g in Figure 2, the shock-absorbing material 104 has a folded portion that is folded from the end in the first direction D1 to the second direction D2, and the folded portion 104C may be attached to the folded portion with an adhesive. In this case, it becomes possible to attach the four corners of the shock-absorbing material 104, which has a rectangular shape when viewed from the third direction D3, by adhesive fixing.
[0089] In the ninth modification, the shape and size of the tray 103 and the shape and size of the shock-absorbing material 104 are not limited to the above examples and can be changed as appropriate. For example, the shape and size of the shock-absorbing material 104 may be the same as the shape and size of the tray 103. In this case, since the shock-absorbing material 104 can be the same as the tray 103, the preparation of the shock-absorbing material 104 can be made even easier. Also, in the ninth modification, an example in which 24 items C are packaged was described. However, the number of items C to be packaged is not particularly limited and may be, for example, 12 items (4 x 3).
[0090] The embodiments and various modifications of the packaging material relating to this disclosure have been described above. However, the packaging material relating to this disclosure is not limited to the embodiments or various modifications described above, and may be further modified within the scope of the gist described in the claims. That is, the configuration, shape, size, number, material and arrangement of each part of the packaging material can be appropriately changed within the scope of the gist described above. In this disclosure, embodiments and the first to eighth modifications have been described, but the packaging material may be a combination of multiple forms from the embodiments and the first to ninth modifications.
[0091] For example, in the above-described embodiment, the break portion 62b, which is the portion to be broken, was explained. As the break portion, it is also possible to use PP (polypropylene) tape, cut tape, or string, and the type of break portion is not particularly limited. Also, as schematically shown in Figure 11, the break portion 92b of the packaging paper 92 of the packaging material may be formed in the portion 92c where a pair of packaging papers 92 are bonded together. In this case, the packaging paper 92 can be broken along the portion 92c at the break portion 92b, making it even easier to open the packaging paper 92.
[0092] In the embodiments described above, a box-shaped tray 3 was described. However, the tray may be plate-shaped, or as described above, U-shaped, and the shape of the tray is not particularly limited. Also, in the embodiments described above, a cylindrical article C had a circular top surface C1 and cylindrical side surfaces C2. However, the shape of the article may be a rectangular parallelepiped, a prismatic shape, etc., and is not particularly limited.
[0093] In the embodiments described above, a packaging material 1 was used to package article C, which is a beverage can. However, the packaging material according to this disclosure may also be, for example, a packaging material for packaging paper cartons, bottles, or PET bottles containing beverages, and the type, shape, size, number, and arrangement of articles packaged in the packaging material can be changed as appropriate.
