Description

Technical Field

[0001] The present disclosure relates to a packaging material, a bracket, and a fastener.

Background Art

[0002] Conventionally, packaging materials used for packaging and transporting parts for automobiles and various machines are known. For example, Patent Document 1 below discloses a packaging material for transporting large and heavy parts such as a transmission of an automobile. This packaging material is used for packaging a plurality of parts to be packaged having a small diameter at one end and a large diameter at the other end, and includes a first packaging member and a second packaging member (Patent Document 1, Summary, Claim 1, Paragraph 0008, etc.).

[0003] The first packaging member is a long member having a plurality of first recesses for holding one end of the part to be packaged. The second packaging member is a long member having second recesses for holding the other end of the part to be packaged, which is disposed on both sides of the first packaging member. In this first packaging member, at least the first recesses located outside in the arrangement direction of the parts to be packaged among the plurality of first recesses are formed at an inclination angle with respect to the direction orthogonal to the longitudinal direction of the first packaging member.

[0004] With such a configuration, the conventional packaging material can reduce the number of material points of the packaging member and reduce the cost. Further, the small-diameter end and the large-diameter other end of the part to be packaged can be alternately reversed and arranged, and the parts to be packaged at both ends in the arrangement direction can be arranged in an inclined posture. Thereby, the dead space can be reduced and the parts to be packaged can be efficiently packaged (Patent Document 1, Paragraph 0010, etc.).

[0005] In addition, an assembly buffer material that has good storage efficiency and can accommodate packaging objects of various shapes and sizes has been proposed. For example, the assembly buffer material described in Patent Document 2 below forms a desired packaging form by appropriately combining side plate members, end plate members, and partition plate members formed only of manufactured board materials such as foamed polyethylene and foamed polypropylene.

[0006] This cushioning material for assembly is provided with a joint groove on the side edges of the side plate member and the end plate member, an insertion hole is provided in the side plate member at a position corresponding to the fitting hole position of the bottom plate member, and the partition plate is formed into a shape corresponding to the object to be packaged, and a protrusion corresponding to the insertion hole is provided on the end edge (Patent Document 2, Summary, Claim 1, Paragraph 0007, etc.). According to this conventional cushioning material for assembly, it is possible to easily achieve cushioning packaging for various objects to be packaged (Ibid., Paragraph 0013, etc.).

Summary of the Invention

Problems to be Solved by the Invention

[0008] When transporting large and heavy items such as automotive transmissions, for example, a plurality of parts are packaged with a packaging material as described in Patent Document 1 above and placed on a metal trolley. Each item placed on the trolley in a state of being packaged with the packaging material is, for example, fixed to the trolley with a fixture such as a band or a strap via a bracket provided on the trolley, and is fixed to the trolley together with the packaging material by the fixture.

[0009] Items packaged and transported with a packaging material such as automotive parts may have their shape, size, or number changed each time due to a change in the vehicle model of the automobile, a change in the design of the parts, or a change in the production plan. The conventional packaging material described in Patent Document 1 above is suitable for transporting large and heavy items, but the shape, size, and number of the items to be packaged correspond to the shape, size, and number of the first concave portion and the second concave portion.

[0010] Therefore, there is room for improvement in this conventional packaging material in that it cannot flexibly respond to changes in the shape, size, or number of items to be packaged. Further, the conventional cushioning material for assembly described in Patent Document 2 can flexibly respond to changes in the shape, size, or number of items to be packaged, but is not suitable for packaging large and heavy items due to its structure.

[0011] Further, when an item packaged with the above conventional packaging material or assembly cushioning material is placed on a cart and fixed to the cart by hanging a fixture such as a belt passed through a bracket provided on the cart, the position of the bracket provided on the cart cannot be changed. Therefore, these conventional packaging materials or assembly cushioning materials have problems with the stability and fixability of the item on the cart when the shape, size, or number of the item to be packaged is changed.

[0012] The present disclosure provides a packaging material that can flexibly respond to changes in the shape, size, or number of large and heavy items to be packaged, and has good stability and fixability of the item to be packaged, and a bracket and a fastener that can be used with the packaging material.

Means for Solving the Problems

[0013] One aspect of the present disclosure is a packaging material for packaging an item, comprising a base member on which the item is placed, a support member detachably attached to the base member to support the item, and a bracket fixed between the base member and the support member, wherein the bracket has a connecting portion for connecting one end of a fixture spanned over the item and an engaging portion for detachably engaging the other end of the fixture.

[0014] According to the packaging material according to the above aspect, an article can be placed on the base member, and the article can be supported by the support member attached to the base member. Therefore, by the cooperation of the base member and the support member, a large and heavy article can be stably supported. Further, by changing at least one of the shape, size, or arrangement of the support member that is detachably attached to the base member and supports the article, it is possible to flexibly respond to changes in the shape, size, or number of articles placed on the base member.

[0015] Also, when attaching the support member to the base member, the packaging material according to the above aspect can fix the bracket between the base member and the support member with one end of a fixture such as a band or a strap connected to the connecting portion of the bracket. Then, the article to be packaged is placed on the base member and supported by the support member, the fixture with one end connected to the connecting portion of the bracket is bridged over the article, and the other end of the fixture is engaged with the engaging portion of the bracket, thereby improving the stability and fixity of the article to be packaged.

[0016] Furthermore, according to the change in the shape, size, or number of articles placed on the base member, by changing at least one of the shape, size, or arrangement of the support member attached to the base member, the position of the bracket fixed between the base member and the support member can be flexibly changed. Therefore, according to the above aspect of the present disclosure, it is possible to flexibly respond to changes in the shape, size, or number of large and heavy articles to be packaged, and it is possible to provide a packaging material with good stability and fixity of the articles to be packaged.

[0017] In the packaging material according to the above aspect of the present disclosure, the bracket may have a plurality of supported surfaces facing a plurality of support surfaces provided on the support member.

[0018] With such a configuration, when transporting an article wrapped in a packaging material, the stability and fixity of the article can be improved. More specifically, an article wrapped in a packaging material is transported, for example, by being placed on a trolley or loaded onto a trailer, a cargo plane, or a cargo ship. Due to the shaking and vibration during transportation, various-directional forces act on the brackets of the packaging material that wraps the article via fixtures spanned over the article.

[0019] At this time, a plurality of supported surfaces of brackets facing different directions can be supported by a plurality of support surfaces of support members facing each supported surface, and the fixity and stability of the brackets fixed between the base member and the support members can be improved. Therefore, the fixture spanned over the article during transportation of the article wrapped in the packaging material can be reliably supported and fixed by brackets having excellent fixity and stability, and the stability and fixity of the wrapped article can be improved.

[0020] The packaging material according to the above aspect of the present disclosure may further include a fastener for fastening the base member and the support member.

[0021] With such a configuration, the base member and the support member attached to the base member can be fastened by the fastener. Thereby, the stability and fixity of the support member with respect to the base member can be improved, and when packaging an article with the packaging material, the stability and fixity of the article placed on the base member and supported by the support member can be improved.

[0022] In the packaging material according to the above aspect of the present disclosure, the base member may have a positioning portion for holding the support member at a predetermined position.

[0023] With such a configuration, when attaching the support member to the base member, the support member can be held in a predetermined position by the positioning portion. Thereby, the support member can support a predetermined position of the article placed on the base member, and the stability and fixity of the article to be packed by the packing material can be improved. Further, the movement of the support member attached to the base member can be prevented, and the stability and fixity of the article supported by the support member can be improved. Note that the positioning portion includes, for example, at least one of a concave portion that engages a part of the support member and a convex portion that restricts the movement of the support member.

[0024] Further, the positioning portion of the base member may be formed in a plurality of patterns corresponding to variations in the number of articles placed on the base member. Such a plurality of patterns of the positioning portion include, for example, a four-pattern when four articles are placed on the base member and a five-pattern when five articles are placed on the base member, etc., a plurality of patterns corresponding to variations in the number of articles to be packed. Thereby, the arrangement of the support member can be easily changed corresponding to the change in the number of articles placed on the base member.

[0025] In the packing material according to the above aspect of the present disclosure, the base member and the support member may be foamed resin molded products.

[0026] With such a configuration, it becomes possible to reduce the weight of the base member and the support member, improve the cushioning property, and improve the recyclability. Further, when transporting the article packed by the packing material, vibrations can be absorbed by the base member and the support member, and the stability and fixity of the article placed on the base member and supported by the support member can be improved.

[0027] Another aspect of the present disclosure is a bracket fixed to a packaging material for packaging an article, the packaging material including a base member on which the article is placed and a support member detachably attached to the base member to support the article, the bracket being fixed between the base member and the support member and having a connecting portion for connecting one end of a fixture spanned over the article and an engaging portion for detachably engaging the other end of the fixture.

[0028] The bracket according to the above aspect can be fixed between a base member on which an article is placed and a support member detachably attached to the base member when packaging the article with the packaging material. Then, one end of a fixture such as a band or a strap can be connected to the connecting portion of the bracket, the fixture can be spanned over the article placed on the base member and supported by the support member, and the other end of the fixture can be engaged with the engaging portion of the bracket. That is, the article can be fixed to the packaging material by the fixture spanned over the article via the bracket fixed between the base member and the support member.

[0029] Furthermore, according to changes in the shape, size, or number of articles placed on the base member, at least one of the shape, size, or arrangement of the support member attached to the base member can be changed, so that the position of the bracket fixed between the base member and the support member can be flexibly changed. Therefore, according to the above aspect of the present disclosure, it is possible to flexibly respond to changes in the shape, size, or number of large and heavy articles to be packaged, and it is possible to provide a bracket with good stability and fixability of the articles to be packaged.

[0030] Another aspect of the present disclosure is a fastener for connecting a first foamed resin molded article and a second foamed resin molded article, including a nut non-rotatably fitted into a recess provided in a first fastening portion of the first foamed resin molded article, and a bolt inserted through a second through-hole penetrating a second fastening portion of the second foamed resin molded article and inserted through a first through-hole penetrating the first fastening portion of the first foamed resin molded article and opening into the recess, the bolt being screwed into the nut fitted into the recess. The nut has a bottomed screw hole that limits the screwing amount of the bolt to a predetermined screwing amount, and the bolt has a total length of the thickness when the first fastening portion and the second fastening portion are elastically compressed and the predetermined screwing amount. The fastener is characterized by this.

[0031] According to the fastener according to the above aspect of the present disclosure, the fastening force for fastening the first fastening portion of the first foamed molded article and the second fastening portion of the second foamed molded article is limited to a predetermined range, and the first fastening portion and the second fastening portion can be firmly fastened while being compressed within the elastic range to prevent damage. Therefore, for example, when the base member and the support member of the packaging material according to the above aspect of the present disclosure are foamed resin molded articles, the first fastening portion of the base member as the first foamed resin molded article and the second fastening portion of the support member as the second foamed resin molded article can be firmly fastened while being compressed within the elastic range to prevent damage.

[0032] Here, the fastening direction of the first foamed molded article and the second foamed molded article by the fastener according to the above aspect is, for example, the depth direction of the first through-hole penetrating the first fastening portion and the second through-hole penetrating the second fastening portion, that is, the axial direction of the bolt inserted through the first through-hole and the second through-hole. In this case, the nut non-rotatably fitted into the recess can be described as the same non-circular nut fitted into a non-circular recess as viewed from the fastening direction. Note that the non-circular shape includes, for example, an elliptical shape, an oval shape, a triangular shape, a quadrangular shape, other polygonal shapes, a cross shape, a star shape, or other irregular shapes.

[0033] In the fastener according to the above aspect of the present disclosure, a disc-shaped washer portion having a diameter larger than that of the head portion may be integrally provided between the cylindrical portion having a threaded portion and the head portion of the bolt.

[0034] With such a configuration, when fastening the first foamed molded product and the second foamed molded product with the fastener according to the above aspect, the stress acting from the end face of the head of the bolt to the second fastening portion of the second foamed molded product can be relaxed by the washer portion having a larger area than the end face of the head. Therefore, when fastening the first foamed molded product and the second foamed molded product with the fastener according to the above aspect, damage to the second fastening portion of the second foamed molded product can be more reliably prevented.

Effects of the Invention

[0035] According to the present disclosure, it is possible to flexibly respond to changes in the shape, size, or number of articles to be packaged, and to provide a packaging material with good stability and fixability of the articles, brackets used for the packaging material, and fasteners.

Embodiments for Carrying Out the Invention

[0037] Hereinafter, embodiments of a packaging material, a bracket, and a fastener according to the present disclosure will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a packaging material, a bracket, and a fastener according to the present disclosure. FIG. 2 is an enlarged perspective view showing an example of a fixture S spanned over an article G packaged by the packaging material 100 of FIG. 1.

[0038] The packaging material 100 of the present embodiment is used, for example, for packaging a large and heavy article G such as a transmission of an automobile. The packaging material 100 is used, for example, for packaging the article G at a shipping source such as a parts factory, and is transported in a state where the article G is packaged from the shipping source to a destination such as an automobile factory, and is unpacked and recovered at the destination and reused.

[0039] One or more articles G packaged by the packaging material 100 are transported, for example, by being placed on a cart or loaded on a trailer, a cargo plane, or a cargo ship. The packaging material 100 supports and fixes the packaged article G to ensure the stability of the article G during transportation, and protects the article G from impacts and vibrations acting during transportation. The packaging material 100 includes, for example, a base member 110, a support member 120, and a bracket 130. Further, the packaging material 100 includes, for example, a fastener 140 (see FIG. 9).

[0040] In the example shown in FIG. 1, the packaging material 100 includes one base member 110, four sets of support members 120, and four pairs of brackets 130. Note that the number of support members 120 and the number of brackets 130 included in the packaging material 100 are not particularly limited. That is, the packaging material 100 can include one or more support members 120 and one or more brackets 130 according to the number of articles G placed on one base member 110.

[0041] As shown in FIG. 2, when packing the article G with the packing material 100, the article G is placed on the base member 110 and supported by the support member 120 detachably attached to the base member 110. In this state, a fixture S such as a fixing band or a fixing strap is further stretched over the article G from one end to the other end of the article G. Thereby, the article G is fixed to the packing material 100 by the fixture S. Although details will be described later, the bracket 130 fixed between the base member 110 and the support member 120 has a connecting portion 131 for connecting one end of the fixture S stretched over the article G and an engaging portion 132 for detachably engaging the other end of the fixture S.

[0042] FIG. 3 and FIG. 4 are a top view and a bottom view of the base member 110 constituting the packing material 100 of FIG. 1, respectively. FIG. 5 is a plan view showing another arrangement pattern of the support member 120 on the base member 110 of FIG. 1.

[0043] The base member 110 is, for example, a foamed resin molded product. As the material of the base member 110, for example, besides Piocelan (registered trademark) which fuses the characteristics of polystyrene and polyolefin, polystyrene, polypropylene, polyethylene, polyethylene terephthalate, etc. can be used. The base member 110 has, for example, a rectangular plate shape and has irregularities on the upper surface. The length of each side of the base member 110 is, for example, 1 m or more, and the thickness of the base member 110 is, for example, 100 mm or less.

[0044] As shown in FIGS. 1 and 3, the base member 110 has, for example, a positioning portion 111 that holds the support member 120 in a predetermined position. More specifically, in the present embodiment, the positioning portion 111 is a recess provided on the upper surface of the base member 110. Note that the positioning portion 111 is not limited to a recess and may be a protrusion provided on the upper surface of the base member 110. The positioning portion 111 has a shape that conforms to a part of the support member 120, engages a part of the support member 120, and holds the support member 120 in a predetermined position on the base member 110.

[0045] The positioning portion 111 includes, for example, a plurality of positioning portions 111A, 111B, 111C having different shapes. Each of the plurality of positioning portions 111A, 111B, 111C is, for example, a recess that fits a part of each of a plurality of support parts 121, 122, 123 having different shapes that constitute the support member 120, and there are portions where they are provided in an overlapping manner with different arrangements. Note that the number of the positioning portions 111A, 111B, 111C having different shapes included in the positioning portion 111 can be changed corresponding to the number of the support parts 121, 122, 123 that constitute the support member 120.

[0046] The positioning portion 111 includes, for example, a plurality of patterns corresponding to variations in the number of articles G placed on the base member 110. More specifically, as shown in FIG. 1, for example, the positioning portion 111 includes two patterns: a four-pattern case where four articles G are placed on the base member 110 and a five-pattern case where five articles G are placed on the base member 110 as shown in FIG. 5. Note that the positioning portion 111 may further include three or more patterns such as a six-pattern.

[0047] As shown in FIG. 4, the base member 110 has, for example, a recess 112 for non-rotatably fitting a nut 141 (see FIG. 9) of a fastener 140 described later. The recess 112 is provided, for example, in a first fastening portion 113 of the base member 110 fastened by the fastener 140. Although details will be described later, the fastening direction of the fastener 140 for fastening the base member 110 and the support member 120 is the thickness direction of the base member 110 perpendicular to the plane of FIG. 4.

[0048] In this case, the recess 112 for non-rotatably fitting the nut 141 can be described as a recess 112 having the same shape as the nut 141 for fitting a non-circular nut 141 as viewed from the fastening direction of the fastener 140. More specifically, the shape of the recess 112 is, for example, a rectangular parallelepiped shape for fitting a rectangular parallelepiped-shaped nut 141 with a predetermined dimensional tolerance, and is rectangular as viewed from the fastening direction of the fastener 140.

[0049] Note that the shape of the recess 112 as viewed from the fastening direction of the fastener 140 can be an arbitrary non-circular shape such as an elliptical shape, an oval shape, a triangular shape, a quadrangular shape, other polygonal shapes, a cross shape, a star shape, or other irregular shapes according to the shape of the nut 141. Each of the plurality of recesses 112 provided on the bottom surface of the base member 110 is provided at a position overlapping with the attachment position of each of the plurality of support members 120 attached to the upper surface of the base member 110 in the fastening direction of the fastener 140.

[0050] Further, the base member 110 has a first through hole 114 through which a bolt 142 (see FIG. 9) of the fastener 140 for fastening the base member 110 and the support member 120 is inserted. Each first through hole 114 penetrates, for example, the first fastening portion 113 of the base member 110 and opens at the bottom surface of each recess 112 and the positioning portion 111 on the upper surface of the base member 110, respectively. The first fastening portion 113 of the base member 110 is a portion fastened to a second fastening portion 125 (see FIG. 5) of the support member 120 by the fastener 140 described later, for example.

[0051] Details will be described later, but each support member 120 attached to the base member 110 has one or more second through-holes 124 (see FIG. 5) that penetrate a second fastening portion 125 fastened to the first fastening portion 113 of the base member 110. The first through-hole 114 of the base member 110 is provided at a position corresponding to each second through-hole 124 of the support member 120 disposed at the mounting position on the upper surface of the base member 110, and allows the bolt 142 of the fastener 140 inserted through each second through-hole 124 of the support member 120 to pass through.

[0052] That is, the recess 112 and the first through-hole 114 of the base member 110 are provided corresponding to the arrangements of the four support members 120 in four patterns when placing four articles G on the base member 110, for example, as shown in FIG. 1. At the same time, the recess 112 and the first through-hole 114 of the base member 110 are provided corresponding to the arrangements of the five support members 120 in five patterns when placing five articles G on the base member 110, for example, as shown in FIG. 5.

[0053] FIG. 6 is a perspective view of the support member 120 constituting the packing material 100 of FIG. 1 as viewed obliquely from above. FIG. 7 is a perspective view of the support member 120 constituting the packing material 100 of FIG. 1 as viewed obliquely from below. FIG. 8 is a perspective view of the bracket 130 constituting the packing material 100 of FIG. 1 as viewed obliquely from above and obliquely from below. FIG. 9 is a perspective view of the fastener 140 constituting the packing material 100 of FIG. 1. FIG. 10 is a front view showing the nut 141 of the fastener 140 of FIG. 9 in cross section.

[0054] The support member 120 is, for example, a foamed resin molded product similar to the base member 110. The support member 120 has, for example, three support parts 121, 122, and 123 with different shapes. Note that each support member 120 may be constituted by one support part, or may be constituted by two or a plurality of four or more support parts. Each of the support parts 121, 122, and 123 has support surfaces 121a, 122a, and 123a for supporting the article G placed on the base member 110, as shown in FIG. 2.

[0055] The first support component 121 has, for example, a concave support surface 121a on its upper surface and is disposed under the front end portion of the article G placed on the base member 110. The support surface 121a of the first support component 121 has, for example, a shape along the outer shape of the lower portion of the front end portion of the article G to be packaged, and supports the front end portion of the large and heavy article G from below over the entire width direction of the article G.

[0056] The first support component 121 has, for example, countersinks 121b at both longitudinal ends in the longitudinal direction of the support component 121 which is the width direction of the article G to be supported. A second through-hole 124 for inserting the bolt 142 of the fastener 140 is provided at the bottom of the countersink 121b. The second through-hole 124 penetrates, for example, the second fastening portion 125 of the first support component 121 that is fastened to the first fastening portion 113 of the base member 110 by the fastener 140, and opens to the bottom surface of the countersink 121b and the bottom surface of the first support component 121, respectively.

[0057] Also, although details will be described later, as shown in FIG. 7, the first support component 121 has, for example, a plurality of support surfaces 121c facing a plurality of supported surfaces 135 of a bracket 130 fixed between the base member 110 and the first support component 121. The plurality of support surfaces 121c of the first support component 121 are provided, for example, as recesses 121d for engaging the bracket 130.

[0058] The second support component 122 has, for example, a concave support surface 122a on its upper surface, similar to the first support component 121, and is disposed under the rear end portion of the article G placed on the base member 110. The support surface 122a of the second support component 122 has, for example, a shape along the outer shape of the lower portion of the rear end portion of the article G to be packaged, and supports the rear end portion of the large and heavy article G from below over the entire width direction of the article G.

[0059] The second support part 122 has, for example, countersinks 122b at both longitudinal ends in the longitudinal direction of the support part 122, which is the width direction of the article G to be supported, similar to the first support part 121. A second through-hole 124 for inserting the bolt 142 of the fastener 140 is provided at the bottom of the countersink 122b. The second through-hole 124 penetrates, for example, the second fastening part 125 of the second support part 122 that is fastened to the first fastening part 113 of the base member 110 by the fastener 140, and opens to the bottom surface of the countersink 122b and the bottom surface of the second support part 122, respectively.

[0060] Also, although details will be described later, the second support part 122 has, similar to the first support part 121, a plurality of support surfaces 122c facing a plurality of supported surfaces 135 of the bracket 130 fixed between the base member 110 and the second support part 122, for example. The plurality of support surfaces 122c of the support part 122 are provided as recesses 122d for engaging the bracket 130, similar to the first support part 121, for example.

[0061] The third support part 123 has, for example, a concave support surface 123a on the upper surface, similar to the first support part 121 and the second support part 122, and is disposed under the upper right rear part of the article G placed on the base member 110. The support surface 123a of the third support part 123 has a shape along the outer shape of the upper right rear part of the article G to be packed, and supports the upper right rear part of the large and heavy article G from below and behind. The third support part 123 has, for example, an elongated columnar shape extending in the vertical direction in a state of being attached to the horizontally arranged plate-shaped base member 110.

[0062] That is, the third support component 123 is provided in a columnar shape that fills the vertical gap formed between the upper right rear part of the article G placed on the horizontally arranged base member 110 and the upper surface of the base member 110. The lower end portion of the third support component 123 has, for example, a plurality of convex portions 123b that engage with a concave positioning portion 111C provided on the upper surface of the base member 110. By engaging these plurality of convex portions 123b with the concave positioning portion 111C provided on the upper surface of the base member 110, the third support component 123 can be detachably attached to the base member 110 without using a fastener 140.

[0063] The bracket 130 has, for example, a bottom plate portion 133 and a main body portion 134 connected to one end of the bottom plate portion 133. The bottom plate portion 133 has, for example, a rectangular planar shape, and the main body portion 134 is connected to one end in the longitudinal direction. With such a configuration, the bracket 130 has a generally L-shaped shape when viewed from the width direction, which is the short side direction of the bottom plate portion 133. The bracket 130 can be manufactured, for example, from a metal such as aluminum. Also, the bracket 130 may be a non-foamed resin molded product made of a resin such as polystyrene, polypropylene, polyethylene, or polyethylene terephthalate.

[0064] The main body portion 134 has, for example, a rectangular cylindrical columnar portion 134a extending in a direction perpendicular to the bottom plate portion 133 and an inclined portion 134b provided between the columnar portion 134a and the bottom plate portion 133. The connecting portion 131 and the engaging portion 132 described above are provided on the columnar portion 134a of the main body portion 134.

The engaging part 132 is, for example, the edge part of a notch provided in an arc shape at the upper part of the columnar part 134a where the rear part of the columnar part 134a is notched from the lower end to the upper end. As shown in FIG. 2, for example, the engaging part 132 engages a hook H attached to the other end of the fixture S whose one end is connected to the connecting part 131, so that the other end of the fixture S is detachably engaged.

[0067] On the upper surface of the bottom plate part 133, for example, a rectangular frame-shaped first convex part 133a and a linear second convex part 133b are provided. The linear second convex part 133b is provided so as to cross the middle part in the longitudinal direction of the rectangular frame-shaped first convex part 133a in the short side direction. On the upper surface of the bottom plate part 133, the height in the protruding direction of the second convex part 133b is higher than the height in the protruding direction of the first convex part 133a. The bottom surface of the bottom plate part 133 is a flat surface without unevenness.

[0068] As shown in FIG. 7, the first convex part 133a and the second convex part 133b on the upper surface of the bottom plate part 133 engage with groove parts 121d1, 122d1 provided in recesses 121d, 122d of the first support part 121 or the second support part 122 constituting the support member 120, respectively. In this way, with the bottom plate part 133 engaged with the recesses 121d, 122d of the first support part 121 or the second support part 122, respectively, the bottom surface of the bottom plate part 133 is flush with the bottom surfaces of the first support part 121 or the second support part 122, for example, without a step.

[0069] When the inclined portion 134b of the main body portion 134 takes the direction perpendicular to the upper surface of the bottom plate portion 133 as the height direction of the bracket 130, an inclined surface 134b1 is provided between the central portion in the height direction of the front portion of the columnar portion 134a and the first convex portion 133a on the upper surface of the bottom plate portion 133. A rectangular recess 134b2 is formed in the inclined surface 134b1 of the inclined portion 134b. As shown in FIG. 7, the inclined portion 134b engages with the respective recesses 121d and 122d of the first support component 121 or the second support component 122 that constitute the support member 120.

[0070] In this way, with the inclined portion 134b of the main body portion 134 engaged with the respective recesses 121d and 122d of the first support component 121 or the second support component 122, the convex portions 121d2 and 122d2 provided in the recesses 121d and 122d respectively engage with the recess 134b2 of the inclined portion 134b. Also, in this state, the front end portion of the columnar portion 134a of the main body portion 134 engages with the respective recesses 121d and 122d of the first support component 121 or the second support component 122 as shown in FIG. 7.

[0071] That is, the bracket 130 has a plurality of supported surfaces 135 facing the plurality of support surfaces 121c and 122c that define these recesses 121d and 122d in a state of being engaged with any of the recesses 121d and 122d of the first support component 121 or the second support component 122 of the support member 120. The plurality of supported surfaces 135 include, for example, the upper surface and side surface of the bottom plate portion 133, the outer surfaces of the first convex portion 133a and the second convex portion 133b, the side surface and front surface of the front end portion of the columnar portion 134a, the side surface and the inclined surface 134b1 of the inclined portion 134b, and the bottom surface and the inner side surface of the recess 134b2 as shown in FIG. 8.

[0072] The fastener 140 is a fastener 140 that connects the base member 110 and the support member 120. The fastener 140 includes a nut 141 and a bolt 142. The nut 141 is non-rotatably fitted into a recess 112 provided in a first fastening portion 113 on the bottom surface of the base member 110 shown in FIG. 4. The nut 141 has, for example, a rectangular parallelepiped shape corresponding to the rectangular parallelepiped-shaped recess 112 of the base member 110.

[0073] The bolt 142 is inserted through a second through hole 124 that penetrates through respective second fastening portions 125 of a first support component 121 and a second support component 122 that constitute the support member 120. Further, the bolt 142 is inserted through a first through hole 114 that penetrates through the first fastening portion 113 of the base member 110 and opens into the recess 112, and is screwed into the nut 141 fitted into the recess 112.

[0074] As shown in FIG. 10, the nut 141 has a bottomed screw hole 141a that limits the screwing amount of the bolt 142 to a predetermined screwing amount SA. That is, the depth D of the bottomed screw hole 141a is equal to, for example, the predetermined screwing amount SA of the bolt 142. The bottomed screw hole 141a is provided, for example, at the central portion in the longitudinal direction of the rectangular parallelepiped-shaped nut 141. Thereby, the area of the side surface of the nut 141 is widened, and when the bolt 142 is screwed into the bottomed screw hole 141a of the nut 141, the stress acting from the side surface of the nut 141 on the recess 112 of the base member 110 can be relaxed.

[0075] The bolt 142 has, for example, a total length L that is the sum of the thickness T when the first fastening portion 113 of the base member 110 and the second fastening portion 125 of the first support component 121 or the second support component 122 of the support member 120 are elastically compressed, and the predetermined screwing amount SA of the bolt 142. Further, the bolt 142 has, for example, a disk-shaped washer portion 142d having a diameter larger than that of the head 142c integrally provided between a cylindrical portion 142b having a threaded portion 142a and the head 142c.

[0076] The nut 141 and bolt 142 that constitute the fastener 140 are non-foamed resin molded products made of a resin such as polystyrene, polypropylene, polyethylene, or polyethylene terephthalate. Also, the nut 141 and bolt 142 may be made of metal, for example.

[0077] Hereinafter, the operations of the packaging material 100, bracket 130, and fastener 140 of this embodiment will be described.

[0078] The packaging material 100 of this embodiment is a packaging material 100 for packaging the article G as described above. The packaging material 100 includes a base member 110 on which the article G is placed, a support member 120 that is detachably attached to the base member 110 and supports the article G, and a bracket 130 that is fixed between the base member 110 and the support member 120. This bracket 130 has a connecting portion 131 that connects one end of a fixture S spanned over the article G, and an engaging portion 132 that detachably engages the other end of the fixture S.

[0079] With such a configuration, the packaging material 100 of this embodiment can place the article G on the base member 110 and further support the article G by the support member 120 attached to the base member 110. Therefore, by the cooperation of the base member 110 and the support member 120, a large and heavy article G can be stably supported. Also, by changing at least one of the shape, size, or arrangement of the support member 120 that is detachably attached to the base member 110 and supports the article G, it is possible to flexibly respond to changes in the shape, size, or number of articles G placed on the base member 110.

[0080] Further, when attaching the support member 120 to the base member 110, the packaging material 100 of the present embodiment can fix the bracket 130 between the base member 110 and 120 with one end of a fixture S such as a band or a strap connected to the connecting portion 131 of the bracket 130. Then, the article G to be packaged is placed on the base member 110 and supported by the support member 120. The fixture S with one end connected to the connecting portion 131 of the bracket 130 is spanned over the article, and by engaging the other end of the fixture S with the engaging portion 132 of the bracket 130, the stability and fixity of the article G to be packaged can be improved.

[0081] Furthermore, as described above, the packaging material 100 of the present embodiment can flexibly change the position of the bracket 130 fixed between the base member 110 and the support member 120 by changing at least one of the shape, size, or arrangement of the support member 120 attached to the base member 110. Therefore, according to the present embodiment, it is possible to flexibly respond to changes in the shape, size, or number of large and heavy articles G to be packaged, and to provide a packaging material 100 with good stability and fixity of the articles G to be packaged.

[0082] Also, in the packaging material 100 of the present embodiment, as described above, the bracket 130 has a plurality of supported surfaces 135 facing the plurality of support surfaces 121c, 122c provided on the support member 120.

[0083] With such a configuration, the stability and fixity of the article G can be improved when the article G packaged by the packaging material 100 is transported. More specifically, the article G packaged by the packaging material 100 is transported, for example, by being placed on a trolley or loaded on a trailer, a cargo plane, or a cargo ship. Due to the shaking and vibration during transportation, various forces act on the bracket 130 of the packaging material 100 that packages the article G via the fixture S spanned over the article G.

[0084] At this time, a plurality of supported surfaces 135 of the brackets 130 facing different directions are supported by a plurality of support surfaces 121c and 122c of the support members 120 facing each supported surface 135, and the fixability and stability of the brackets 130 fixed between the base member 110 and the support members 120 can be improved. Therefore, the fixture S bridged over the article G during the conveyance of the article packed by the packing material 100 can be surely supported and fixed by the brackets 130 having excellent fixability and stability, and the stability and fixability of the packed article G can be improved.

[0085] In addition, the packing material 100 of the present embodiment further includes a fastener 140 for fastening the base member 110 and the support member 120.

[0086] With such a configuration, the packing material 100 of the present embodiment can fasten the base member 110 and the support member 120 attached to the base member 110 with the fastener 140. Thereby, the stability and fixability of the support member 120 with respect to the base member 110 are improved, and the stability and fixability of the article G placed on the base member 110 and supported by the support member 120 during the packing of the article G by the packing material 100 can be improved.

[0087] In addition, in the packing material 100 of the present embodiment, the base member 110 has a positioning portion 111 for holding the support member 120 at a predetermined position.

[0088] With such a configuration, when the support member 120 is attached to the base member 110, the support member 120 can be held at a predetermined position by the positioning portion 111. Thereby, the support member 120 can support a predetermined position of the article G placed on the base member 110, and the stability and fixability of the article G packed by the packing material 100 can be improved. Further, the movement of the support member 120 attached to the base member 110 can be prevented, and the stability and fixability of the article G supported by the support member 120 can be improved.

[0089] Further, in the packaging material 100 of the present embodiment, the base member 110 and the support member 120 are foamed resin molded products.

[0090] With such a configuration, it is possible to reduce the weight of the base member 110 and the support member 120, improve the cushioning property, and improve the recyclability. Further, when the article G packaged by the packaging material 100 is transported, vibrations can be absorbed by the base member 110 and the support member 120, and the stability and fixity of the article G placed on the base member 110 and supported by the support member 120 can be improved.

[0091] By the way, in a conventional packaging material, for example, a packaging material that packages an article is placed on a cart, and a fixture such as a band or a strap is passed around the packaging material via a bracket provided on the cart, and the packaging material is fixed on the cart by the fixture, thereby stabilizing the packaged article. In this case, the position of the bracket provided on the cart cannot be changed. Therefore, when the shape, size, or number of the articles to be packaged is changed, the conventional packaging material has problems with the stability and fixity of the articles on the cart.

[0092] On the other hand, the bracket 130 of the present embodiment is fixed to the packaging material 100 for packaging the article G. The packaging material 100 includes, as described above, a base member 110 on which the article G is placed, and a support member 120 that is detachably attached to the base member 110 and supports the article G. The bracket 130 is fixed between the base member 110 and the support member 120, and has a connecting portion 131 that connects one end of the article G that is bridged over the article G, and an engaging portion 132 that detachably engages the other end of the fixture S.

[0093] With such a configuration, when packing the article G with the packing material 100, the bracket 130 of the present embodiment can be fixed between the base member 110 on which the article G is placed and the support member 120 detachably attached to the base member 110. Then, one end of a fixing tool S such as a band or a strap is connected to the connecting portion 131 of the bracket 130, the fixing tool S is stretched over the article G placed on the base member 110 and supported by the support member 120, and the other end of the fixing tool S can be engaged with the engaging portion 132 of the bracket 130. That is, the article G can be fixed to the packing material 100 by the fixing tool S stretched over the article G via the bracket 130 fixed between the base member 110 and the support member 120.

[0094] Furthermore, the bracket 130 of the present embodiment can flexibly change the position of the bracket 130 by changing at least one of the shape, size, or arrangement of the support member 120 attached to the base member 110 according to changes in the shape, size, or number of the articles G placed on the base member 110. Therefore, according to the present embodiment, it is possible to flexibly cope with changes in the shape, size, or number of large and heavy articles G to be packed, and it is possible to provide a bracket 130 with good stability and fixability of the articles G to be packed.

[0095] In addition, when the support member 120 of the foamed resin molded product is fastened to the base member 110 of the foamed resin molded product with a fastener such as an ordinary bolt or nut in the packing material 100 of the present embodiment, there is a risk that the fastening force of the fastener becomes excessive and the base member 110 or the support member 120 is damaged. Also, in order to avoid damage to the base member 110 and the support member 120, if the fastening force by an ordinary fastener is insufficient, the base member 110 and the support member 120 cannot be firmly fastened, and there is a risk that the stability is impaired.

[0096] In contrast, the fastener 140 of the present embodiment is a fastener 140 that connects the base member 110 as the first foamed resin molded product and the support member 120 as the second foamed resin molded product. The fastener 140 includes a nut 141 and a bolt 142. The nut 141 is non-rotatably fitted into a recess 112 provided in a first fastening portion 113 of the first foamed resin molded product. The bolt 142 is inserted through a second through-hole 124 that penetrates a second fastening portion 125 of the second foamed resin molded product, and is also inserted through a first through-hole 114 that penetrates the first fastening portion 113 of the first foamed resin molded product and opens into the recess 112, and is screwed into the nut 141 fitted into the recess 112. The nut 141 has a bottomed screw hole 141a that limits the screwing amount of the bolt 142 to a predetermined screwing amount SA. The bolt 142 has a total length L of the thickness T when the first fastening portion 113 and the second fastening portion 125 are elastically compressed and the predetermined screwing amount SA.

[0097] According to the fastener 140 of the present embodiment, the fastening force for fastening the first fastening portion 113 of the base member 110 as the first foamed molded product and the second fastening portion 125 of the support member 120 as the second foamed molded product can be limited to a predetermined range. Therefore, according to the fastener 140 of the present embodiment, the first fastening portion 113 of the base member 110 as the first foamed resin molded product and the second fastening portion 125 of the support member 120 as the second foamed resin molded product can be firmly fastened while being compressed within the elastic range to prevent damage.

[0098] Further, in the fastener 140 of the present embodiment, a disc-shaped washer portion 142d having a diameter larger than that of the head 142c is integrally provided between the cylindrical portion 142b having a screw portion 142a and the head 142c of the bolt 142.

[0099] With such a configuration, when fastening the base member 110 as the first foamed molded product and the support member 120 as the second foamed molded product by the fastener 140 of the present embodiment, the stress acting from the end face of the head 142c of the bolt 142 to the second fastening portion 125 of the support member 120 can be relaxed by the washer portion 142d having a larger area than the end face of the head 142c. Therefore, when fastening the base member 110 and the support member 120 according to the present embodiment, damage to the second fastening portion 125 of the support member 120 can be more reliably prevented.

[0100] As described above, according to the present embodiment, it is possible to flexibly respond to changes in the shape, size, or number of the articles G to be packaged, and to provide the packaging material 100 having good stability and fixability of the articles G, and the brackets 130 and fasteners 140 used for the packaging material 100.

[0101] As described above, the embodiments of the packaging material, brackets, and fasteners according to the present disclosure have been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and even if there are design changes and the like within the scope not departing from the gist of the present disclosure, they are included in the present disclosure. For example, the packaging material may include a fixture bridged over the article.
