<First embodiment>
(Package 1000)
FIG. 1 is a perspective view schematically showing a package 1000 according to the first embodiment. FIG. 2 is an exploded perspective view of FIG. 1. Note that the object to be packaged 1 shown in FIGS. 1 and 2 is shaded for easy identification.

As shown in FIGS. 1 and 2, the package 1000 includes an object 1 to be packed and a packing material 100 for packing the object 1. The packaging material 100 includes a first packaging material 10A and a second packaging material 20A. The first packaging material 10A is constructed by a first member 11A having a first base portion 13A and at least a pair of first convex portions 14A located above the first base portion 13A, and a pair of first convex portions 14A. and a first construction member 15. The second packaging material 20A has a second base portion 23A and at least a pair of second convex portions 24A that are located below the second base portion 23A and do not overlap with the first convex portions 14A. It includes a member 21A and a second construction member 25 that is constructed over the pair of second convex portions 24A. Then, the first member 11A and the second member 21A are separated, and the object to be packed 1 is held between the first construction member 15 and the second construction member 25.

The package 1000 can hold the object 1 to be packed regardless of its thickness, and protect the object 1 from external force and impact. The package 1000 is configured such that when the object to be packed 1 is held between the first construction member 15 and the second construction member 25, the first member 11A and the second member 21A are separated. With such a configuration, by applying an external force that causes the first member 11A and the second member 21A to approach each other, the force of the first construction member 15 and the second construction member 25 to clamp the object to be packed 1 can be reduced. can be increased. Thereby, regardless of the thickness of the object to be packed 1, even a thin object to be packed like the object to be packed 1 can be held, and the object to be packed can be protected from external force and impact.

In addition, the package 1000 is packed with the object 1 sandwiched between the first construction member 15 and the second construction member 25, and the object 1 is directly connected to the first member 11A and the second member 21A. Since they are not in contact with each other, even if an unintended impact is applied to the first member 11A and the second member 21A, damage to the object to be packed 1 can be reduced.

Each element constituting the package 1000 will be described below.

(Packaged item 1)
The object to be packed 1 is a member that is packed in the packing body 1000 by being held between the first packing material 10A and the second packing material 20A. The size of the object to be packed 1 in plan view is smaller than the first packaging material 10A and the second packaging material 20A. When there is one object to be packed held between the first packing material 10A and the second packing material 20A, the size of the packing object 1 in a plan view is, for example, 60% of the first packing material 10A and the second packing material 20A. % or more and 80% or less. Further, the number of objects 1 to be packed that are held between the first packing material 10A and the second packing material 20A is not limited to one, but may be plural. When a plurality of objects 1 to be packed are held between the first packing material 10A and the second packing material 20A, in a plan view, the objects 1 to be packed are the plurality of first convex portions 14A of the first packing material 10A and the second packing material. They are spaced apart from each other so as not to overlap with the second convex portion 24A of 20A. The plurality of objects 1 to be packed may have the same or different shapes in plan view. Furthermore, the plurality of objects 1 to be packed may have the same or different thicknesses. If the thickness of each object to be packed is the same, it is possible to suppress unevenness in the force for holding each object to be packed.
The object to be packed 1 may have a thickness of, for example, 0.5 mm or more and 50 mm or less.

The object to be packed 1 is, for example, a plate-shaped member. The plate member is, for example, a planar light source. A planar light source includes, for example, a light guiding member having a plurality of through holes, a plurality of light sources are arranged in two dimensions on an FPC board (flexible printed circuit board), and the light source is placed in the through hole of the light guiding member. The light guide member is arranged on the FPC board so that the light guide member is positioned at the same position. For example, a light emitting diode can be used as the light source. For example, polycarbonate can be used for the light guide member. The dimensions of the planar light source are, for example, about 1 mm in thickness and about 350 mm x about 200 mm in plan view. In the example shown in FIG. 1 or 2, the shape of the object to be packed 1 in plan view is a rectangle. However, as shown in FIG. 3, the shape of the object to be packed 1 in plan view may be a shape based on a rectangle and having one or more portions projecting outward from one side of the rectangle. Further, the shape of the object to be packed 1 in plan view is not limited to a rectangle, but may be a square. The corners of the rectangle or square may be angular or rounded.

(packing material 100)
The packing material 100 is a member for packing the object 1 to be packed. The packaging material 100 includes a first packaging material 10A and a second packaging material 20A.

(1st packaging material 10A)
The first packing material 10A is a member that is located below the object to be packed 1 and holds the object to be packed 1 from below. The first packaging material 10A is constructed by a first member 11A having a first base portion 13A and at least a pair of first convex portions 14A located above the first base portion 13A, and a pair of first convex portions 14A. and a first construction member 15.

(First member 11A)
As shown in FIG. 4, the first member 11A has a frame shape in plan view. The first member 11A is provided so as to surround the object to be packed 1 in a plan view. The shape of the first member 11A in plan view is, for example, a rectangle. However, the shape of the first member 11A in plan view is not limited to a rectangle, but may be a square. In the case of a rectangle or square, the corners are not limited to being angular; for example, they may be rounded. The shape of the first member 11A in plan view may correspond to the shape of the object to be packed 1 in plan view, or may be a shape different from the shape corresponding to the shape of the object to be packed 1 in plan view.

In the example shown in FIG. 4, the first member 11A includes four frame sides: a first frame side 12a, a second frame side 12b, a third frame side 12c, and a fourth frame side 12d. In the lateral direction of the first member 11A, which is rectangular in plan view, the first frame side 12a and the second frame side 12b face each other. Further, the third frame side 12c and the fourth frame side 12d face each other in the longitudinal direction of the first member 11A, which is rectangular in plan view.

(First base 13A, first convex portion 14A)
The first member 11A includes a first base portion 13A and at least a pair of first convex portions 14A located above the first base portion 13A. The first base 13A is a part that supports the first protrusion 14A. The first convex portion 14A is a portion provided for constructing the first construction member 15.

As shown in FIG. 2, in the first frame side 12a of the first member 11A, the end of the first base 13A is connected to the end of the first convex part 14A, and the first base 13A and the first convex part 14A are alternately arranged. It consists of being placed in The first frame side 12a extends linearly in plan view. The same applies to the second frame side 12b, the third frame side 12c, and the fourth frame side 12d in the first member 11A.

In the example shown in FIG. 2, the first frame side 12a includes four first base portions 13A and three first convex portions 14A. Similarly, the second frame side 12b includes four first base portions 13A and three first convex portions 14A. Further, the third frame side 12c includes three first base portions 13A and two first convex portions 14A. Similarly, the fourth frame side 12d includes three first base portions 13A and two first convex portions 14A.

The first member 11A has at least one pair of first convex portions 14A. In the example shown in FIG. 2, the first member 11A includes five pairs of first convex portions 14A. Three pairs of first convex portions 14A are provided on the first frame side 12a and the second frame side 12b, and two pairs of first convex portions 14A are provided on the third frame side 12c and the fourth frame side 12d. Note that the pair of first convex portions may be first convex portions 14A provided on adjacent frame sides (for example, the first frame side 12a and the third frame side 12c) of the frame body.

The pair of first convex portions 14A is not limited to being provided in plural numbers, and may be one. For example, a pair of first convex portions 14A can be provided on the first frame side 12a and the second frame side 12b. In this case, the third frame side 12c and the fourth frame side 12d, which are not provided with the first convex portion 14A, are composed of only the first base portion 13A.

The first convex portion 14A is located above the first base portion 13A. In other words, the first convex portion 14A protrudes toward the second packaging material 20A side. The first convex portion 14A has an upper portion 14a and a pair of first side portions 14b connected to both ends of the upper portion 14a. The first base portion 13A is connected to an end portion of the first side portion 14b of the first convex portion 14A that is opposite to the end portion that is connected to the upper portion 14a.

The upper part 14a is a part provided for arranging a first construction member 15, which will be described later. The length in the extending direction of the upper part 14a can be made the same as the length in the extending direction of the first base 13A, for example, as shown in the example of FIG. 1 or 2.

The first base portion 13A, the upper portion 14a and the first side portion 14b of the first convex portion 14A are all rod-shaped members, and may be in the shape of a square column or a column. The upper part 14a of the first convex part 14A shown in the example of FIG. 1 or 2 has a quadrangular prism shape and has a rectangular upper surface, side surfaces, and lower surface. The upper surface is a surface facing the second member. Further, the lower surface is a surface located on the opposite side to the upper surface. The side surface is a surface connecting the top surface and the bottom surface. The upper surface of the upper portion 14a of the first convex portion 14A may be a flat surface or may be a curved surface that swells upward.

The pair of first side portions 14b of the first convex portion 14A are preferably inclined so that the distance between the pair of first side portions 14b becomes wider toward the first base portion 13A side. Furthermore, in the second convex portion 24A, which will be described later, the pair of second side portions 24b of the second convex portion 24A are inclined such that the distance between the pair of second side portions 24b becomes wider toward the second base 23A side. It is preferable to do so. With these configurations, when the object to be packed 1 is sandwiched between the first construction member 15 and the second construction member 25 with the upper part 14a of the first convex portion 14A and the second base 23A facing each other, the first member The first member 11A and the second member 21A can be brought closer to each other while maintaining the state in which the first member 11A and the second member 21A do not contact each other. Thereby, the force with which the first construction member 15 and the second construction member 25 clamp the object to be packed 1 can be increased. Further, in the first member 11A, one first side portion 14b of the first convex portion 14A and a first side portion of the adjacent first convex portion 14A that is connected to the first side portion 14b via the first base portion 13A. 14b is preferably narrowed toward the first base 13A side. Further, in the second member 21A, one second side portion 24b of the second convex portion 24A and a second side portion of the adjacent second convex portion 24A that is connected to the second side portion 24b via the second base portion 23A. 24b is preferably narrowed toward the second base 23A side.

The angle formed between the upper portion 14a and the first side portion 14b of the first convex portion 14A is preferably larger than 90 degrees and smaller than 160 degrees, and more preferably larger than 130 degrees and smaller than 140 degrees. Thereby, the height of the first convex portion 14A can be ensured while suppressing contact between the first member 11A of the first packaging material 10A and the second member 21A of the second packaging material 20A. In addition, "the height of the first convex part 14A" refers to the height from the end of the first side part 14b on the first base side to the upper part in the direction orthogonal to the upper surface of the upper part 14a when the upper part 14a is in the shape of a square prism. This is the length to the top surface of 14a. Further, when the upper part 14a is columnar, the length is the length from the end of the first side part 14b on the first base side to the upper end of the upper part 14a in the direction connecting the upper end and the lower end of the circle.

The height of the first convex portion 14A is preferably at least the same as the thickness of the object 1 to be packed and at most 10 times the thickness of the object 1 to be packed. Thereby, it is possible to prevent the package 1000 from becoming excessively thick. As a result, when storing the packages 1000 in a transport case (for example, a cardboard box or a container), the number of packages 1000 that can be stored in the transport case can be increased. The height of the first convex portion 14A can be, for example, 6 mm when the thickness of the object to be packed 1 is 1 mm.

In the example shown in FIGS. 1 and 2, the heights of the five pairs of first convex portions 14A provided on the first member 11A are all the same. However, the height of the pair of first protrusions 14A provided on the first frame side 12a and the second frame side 12b is the same as that of the pair of first protrusions 14A provided on the third frame side 12c and the fourth frame side 12d. It may be higher or lower than the height.

When two or more first protrusions 14A are provided on one frame side, it is preferable that the interval between the upper parts 14a of adjacent first protrusions 14A be shorter than the length of the outer shape of the object to be packed 1. Thereby, the object to be packed 1 can be held by the first construction member 15 installed on the first convex portion 14A.

The material of the first base portion 13A and the first convex portion 14A is, for example, thermosetting resin, thermoplastic resin, metal, wood, or the like. When producing the first member 11A using resin, it can be produced by integrally molding it by compression molding, transfer molding, or injection molding. In addition, the first frame side 12a, the second frame side 12b, the third frame side 12c, and the fourth frame side 12d are each manufactured integrally, and the ends of each frame side are bonded together using an adhesive to form a flat surface. It is also possible to produce the first member 11A which is frame-shaped in appearance. Further, a plurality of first base parts 13A and a plurality of first convex parts 14A are respectively produced, and a frame side is produced by bonding the first base part 13A and the first convex part 14A using an adhesive, and the ends of the frame side are It is also possible to create a frame-shaped first member in a plan view by using an adhesive. When producing the first member 11A using wood, a plurality of first bases 13A and a plurality of first protrusions 14A are respectively produced, and the first bases 13A and the first protrusions 14A are bonded together using an adhesive. A frame-shaped first member can be manufactured by creating a frame side and using an adhesive between the ends of the frame side in a plan view. When producing the first member 11A using metal, it may be produced by pressing a frame-shaped member with a metal mold or the like, or it may be produced using a mold. The first base portion 13A and the first convex portion 14A may be made of the same material or may be made of different materials. Note that the first member 11A may be purchased and prepared.

The thickness of the first base portion 13A is, for example, 6 mm. The thickness of the first side portion 14b and the upper portion 14a of the first convex portion 14A may be the same as or different from the thickness of the first base portion 13A.

The number of first convex portions 14A provided on opposing frame sides is not limited to the same number as shown in FIG. 2, but may be different. When the number of first protrusions 14A provided on the opposing frame sides is different, for example, three first protrusions 14A are provided on the first frame side 12a, and two first protrusions 14A are provided on the second frame side 12b. can be provided. In this case, for example, the first construction member 15 can be constructed from one first convex portion 14A provided on the second frame side 12b toward two first convex portions 14A on the first frame side 12a.

In addition, when a plurality of objects 1 to be packed are arranged side by side within the frame of the first member 11A, a frame including the first convex portion 14A and the first base 13A is provided in the area between the objects 1 to be packed in the first member 11A. You can add edges. The same applies to the second member 21A.

Note that the first convex portion 14A is not limited to being composed of the upper portion 14a and the first side portion 14b, but may be composed only of the first side portion 14b. In this case, the first convex portion 14A can have a triangular shape in cross-section. Further, the shape of the first convex portion 14A in a cross-sectional view may be a semicircle. The same applies to the second convex portion 24A.

(First construction member 15)
The first construction member 15 is a member for holding the object 1 to be packed, and is used together with the second construction member 25 described later to sandwich the object 1 to be packed. The first construction member 15 is constructed over the pair of first convex portions 14A.

In the example shown in FIG. 2, the first packaging material 10A includes five first construction members 15. Three first construction members 15 are installed on the first convex portion 14A provided on the first frame side 12a and the first convex portion 14A provided on the second frame side 12b, and three first construction members 15 are provided on the third frame side 12c. Two first construction members 15 are provided that are constructed between the first convex portion 14A provided on the first convex portion 14A and the first convex portion 14A provided on the second frame side 12b. In the example shown in FIG. 2, the first construction member 15 is provided on all the first convex portions 14A.

In the example shown in FIG. 2, three first construction members 15 are constructed between the first convex portion 14A provided on the first frame side 12a and the first convex portion 14A provided on the second frame side 12b. parallel to each other. The two first construction members 15 installed between the first convex portion 14A provided on the third frame side 12c and the first convex portion 14A provided on the fourth frame side 12d are parallel to each other. Moreover, the first construction member 15 is constructed between the first convex portion 14A provided on the first frame side 12a of the first member 11A and the first convex portion 14A provided on the second frame side 12b, and The first convex portion 14A provided on the third frame side 12c of the member 11A and the first convex portion 14A provided on the fourth frame side 12d of the member 11A are orthogonal to each other.

The first construction member 15 may be constructed in two directions, the longitudinal direction and the lateral direction of the first member 11A, as shown in FIG. 2, or may be constructed only in either direction. The first construction members 15 installed in the same direction may be parallel to each other, or as shown in FIG. 6A, the two first construction members 15 may intersect. As shown in FIG. 6B, two first construction members 15 are disposed on the first convex portion 14A of the second frame side 12b. 14A may be constructed.

The first construction member 15 may be constructed between the first convex portion 14A provided on the first frame side 12a and the first convex portion 14A provided on the third frame side 12c or the fourth frame side 12d. Similarly, the first construction member 15 is constructed between a first convex portion 14A provided on the second frame side 12b and a first convex portion 14A provided on the third frame side 12c or the fourth frame side 12d. Good too.

In the example shown in FIGS. 1 and 2, the width of the first construction member 15 is the same as the length of the upper portion 14a of the first convex portion 14A in the extending direction. However, the width of the first construction member 15 may be wider or narrower than the length of the upper portion 14a of the first convex portion 14A in the extending direction. When the width of the first construction member 15 is wider than the length of the upper part 14a in the extending direction, the first construction member 15 may be arranged astride two adjacent first protrusions 14A via the first base 13A. good. Here, the "width of the first construction member 15" is the length of the first construction member 15 in the direction perpendicular to the construction direction and the thickness direction of the first construction member 15.

The length of the first construction member 15 in the construction direction may be the same as the length between the first projections 14A in the pair of first projections 14A, or may be longer. The first construction member 15 may be constructed so that there is no slack, or it may be constructed in a slack state.

When a plurality of first construction members 15 are provided, the object to be packed 1 can be held stably. However, depending on the size of the first construction member 15 and the size of the object to be packed 1, the number of the first construction members 15 may be one. The first construction member 15 is not limited to being provided on all the first convex portions 14A. That is, there may be a first convex portion 14A in which the first construction member 15 is not provided.

It is preferable that the first construction member 15 is an elastic body. The tensile modulus of the first construction member 15 is preferably 1.0 MPa or more. As a result, even if excessive force is applied to the first packaging material 10A or the second packaging material 20A in a state where the object to be packed 1 is held between the first construction member 15 and the second construction member 25, the first construction member 15 and the second construction member 25 It is possible to suppress excessive force from being applied to the object to be packed 1 due to the bending of the member 15. As the material of the first construction member 15, for example, resin such as rubber or plastic can be used. In the example shown in FIGS. 1 and 2, the first construction member 15 has a sheet shape. Each first construction member 15 may be composed of a single sheet, or may be composed of a plurality of members arranged or stacked. When a plurality of members are arranged or overlapped, each member may be parallel to each other, or some members may intersect with each other. The plurality of members may be made of the same material or may be made of different materials. Further, the first construction member 15 may be a mesh-like sheet. The thickness of the first construction member 15 is, for example, 100 μm. The thickness of the first construction member 15 may be uniform throughout, or may differ partially.

In the example shown in FIG. 2, the first construction member 15 is constructed on the upper surface of the upper portion 14a of the first convex portion 14A. The first construction member 15 is bonded to the upper surface of the first convex portion 14A using an adhesive, for example. Alternatively, a member made of a material different from that of the first construction member may be provided at the end of the first construction member, and this member and the first convex portion may be joined via an adhesive. Note that the first construction member 15 is not limited to being joined to the upper surface of the upper portion 14a of the first convex portion 14A, but may be joined to the lower surface or side surface of the upper portion 14a. Further, two or more of the upper surface, side surfaces, and lower surface of the upper portion 14a may be joined. In addition, the "side surface" here refers to the side surface of the side which is not connected to the 1st side part 14b among the four side surfaces which connect the upper surface and the lower surface of the upper part 14a.

When the object to be packed 1 is sandwiched between the first construction member 15 and the second construction member 25, in order to prevent the object to be packed 1 from slipping, at least one of the first construction member 15 and the second construction member 25 is covered. An anti-slip finish can be applied to the surface facing the packaged object 1. For example, the surface of the first construction member 15 may be provided with irregularities, or may be coated with a material that has an anti-slip effect. The same applies to the second construction member 25 and the third construction member 35, which will be described later.

(Second packaging material 20A)
The second packing material 20A is a member that is located above the object to be packed 1 and holds the object to be packed 1 from above. The second packaging material 20A is constructed over a second member 21A having a second base 23A and at least a pair of second protrusions 24A located below the second base 23A, and a pair of second protrusions 24A. and a second construction member 25.

(Second member 21A)
The second member 21A has a frame shape in plan view, as shown in FIG. The second member 21A is provided so as to surround the object to be packed 1 in a plan view. The shape of the second member 21A in plan view is the same as that described for the first member 11A, so the description thereof will be omitted. In the example shown in FIG. 5, the second member 21A is configured with four frame sides: a fifth frame side 22a, a sixth frame side 22b, a seventh frame side 22c, and an eighth frame side 22d. In the lateral direction of the second member 21A, the fifth frame side 22a and the sixth frame side 22b face each other. In the longitudinal direction of the second member 21A, the seventh frame side 22c and the eighth frame side 22d face each other.

(Second base 23A, second convex portion 24A)
The second member 21A includes a second base portion 23A and at least a pair of second convex portions 24A located below the second base portion 23A. The second base portion 23A is a portion that supports the second convex portion 24A. The second convex portion 24A is a portion provided for constructing the second construction member 25.

As shown in FIG. 2, in the fifth frame side 22a of the second member 21A, the end of the second base 23A is connected to the end of the second convex part 24A, and the second base 23A and the second convex part 24A are alternately arranged. It consists of being placed in The fifth frame side 22a extends linearly in plan view. The same applies to the sixth frame side 22b, seventh frame side 22c, and eighth frame side 22d in the second member.

In the example shown in FIG. 2, the fifth frame side 22a includes three second base portions 23A and two second convex portions 24A. Similarly, the sixth frame side 22b includes three second base portions 23A and two second convex portions 24A. Further, the seventh frame side 22c includes two second base portions 23A and one second convex portion 24A. Similarly, the eighth frame side 22d includes two second base portions 23A and one second convex portion 24A. Note that the convex portion located below the second base portion 23A, which is present at the end of each frame side, is not the second convex portion 24A.

The second member 21A has at least one pair of second convex portions 24A. In the example shown in FIG. 2, the second member 21A includes three pairs of second convex portions 24A. Two pairs of second convex portions 24A are provided on the fifth frame side 22a and the sixth frame side 22b, and one pair of second convex portions 24A is provided on the seventh frame side 22c and the eighth frame side 22d. Note that the pair of second convex portions 24A may be second convex portions 24A disposed on adjacent frame sides (for example, the fifth frame side 22a and the seventh frame side 22c) of the frame body. Similar to the pair of first protrusions 14A, the number of the pair of second protrusions 24A is not limited to a plurality, and may be one.

The second convex portion 24A is located below the second base portion 23A. In other words, the second convex portion 24A protrudes toward the first packaging material 10A side. The second convex portion 24A has a lower portion 24a and a pair of second side portions 24b connected to both ends of the lower portion 24a. The second base portion 23A is connected to an end portion of the side portion of the second convex portion 24A opposite to the end portion connected to the lower portion 24a.

The lower part 24a is a part provided for arranging a second construction member 25, which will be described later. The length in the extending direction of the lower part 24a can be made the same as the length in the extending direction of the second base 23A, for example, as shown in the example of FIG. 1 or 2.

The second base portion 23A, the lower portion 24a of the second convex portion 24A, and the second side portion 24b are all rod-shaped members, and may be square columnar or columnar. The lower portion 24a of the second convex portion 24A shown in the example of FIG. 1 or 2 has a quadrangular prism shape and has a rectangular upper surface, side surfaces, and lower surface. The lower surface is a surface facing the first member. Further, the upper surface is a surface located on the opposite side to the lower surface. The side surface is a surface connecting the top surface and the bottom surface. The lower surface of the lower part 24a of the second convex portion 24A may be a flat surface or may be a curved surface that swells downward.

The pair of second side portions 24b of the second convex portion 24A are preferably inclined so that the distance between the pair of second side portions 24b becomes wider toward the second base portion 23A side.

The angle between the lower part 24a of the second convex part 24A and the second side part 24b is larger than 90 degrees and smaller than 160 degrees, similar to the angle between the upper part 14a and the first side part 14b of the first convex part 14A. It is preferable to make the angle smaller, and more preferably larger than 130 degrees and smaller than 140 degrees.

The height of the second convex portion 24A is preferably at least the same as the thickness of the object 1 to be packed and at most 10 times the thickness of the object 1 to be packed. In addition, "the height of the second convex part 24A" means, when the lower part 24a has a quadrangular prism shape, from the end of the second side part 24b on the second base side to the lower part in the direction orthogonal to the lower surface of the lower part 24a. This is the length to the bottom surface of 24a. Further, when the lower part 24a is columnar, the length is the length from the end of the second side part 24b on the second base side to the lower surface of the lower part 24a in the direction connecting the upper end and the lower end of the circle.

In the example shown in FIGS. 1 and 2, the heights of the three pairs of second convex portions 24A provided on the second member 21A are all the same. However, the height of the pair of second convex portions 24A provided on the fifth frame side 22a and the sixth frame side 22b is the same as that of the pair of second convex portions 24A provided on the seventh frame side 22c and the eighth frame side 22d. It may be higher or lower than the height.

When two or more second convex portions 24A are provided on one frame side, it is preferable that the interval between the lower portions 24a of adjacent second convex portions 24A be shorter than the length of the outer shape of the object to be packed 1.

The second base portion 23A and the second convex portion 24A may be made of the same material as the first base portion 13A and the first convex portion 14A. The second member can be manufactured by the same method as described for the first member, so the description thereof will be omitted. Further, the second member may also be purchased and prepared in the same manner as the first member.

The thickness of the second base portion 23A is, for example, 6 mm. The thickness of the second side portion 24b and lower portion 24a of the second convex portion 24A may be the same as or different from the thickness of the second base portion 23A.

(Second construction member 25)
The second construction member 25 is a member for holding the object 1 to be packed, and is used together with the first construction member 15 described above to sandwich the object 1 to be packed. The second construction member 25 is constructed over the pair of second convex portions 24A.

In the example shown in FIG. 2, the second member 21A includes three second construction members 25. Two second construction members 25 are installed on the second protrusion 24A provided on the fifth frame side 22a and the second protrusion 24A provided on the sixth frame side 22b, and two second construction members 25 are provided on the seventh frame side 22c. One second construction member 25 is provided, which is constructed between the second convex portion 24A provided on the eighth frame side 22d and the second convex portion 24A provided on the eighth frame side 22d. In the example shown in FIG. 2, the second construction member 25 is provided on all the second convex portions 24A.

In the example shown in FIG. 2, the two second construction members 25 are constructed between the second convex portion 24A provided on the fifth frame side 22a and the second convex portion 24A provided on the sixth frame side 22b. parallel to each other. Further, a second construction member 25 is installed between the second convex portion 24A provided on the seventh frame side 22c and a second convex portion 24A provided on the eighth frame side 22d, and a second construction member 25 is installed on the seventh frame side 22c. The second convex portion 24A provided on the eighth frame side 22d and the second construction member 25 installed on the second convex portion 24A provided on the eighth frame side 22d are perpendicular to each other.

The second construction member 25 may be constructed in two directions, the longitudinal direction and the lateral direction of the second member 21A, as shown in the example of FIG. 2, or may be constructed only in either direction. The second construction members 25 installed in the same direction may be parallel to each other like the first construction members 15, or the two first construction members 15 may intersect.

The second construction member 25 may be constructed between the second convex portion 24A provided on the fifth frame side 22a and the second convex portion 24A provided on the seventh frame side 22c or the eighth frame side 22d. Similarly, the second construction member 25 is constructed between a second convex portion 24A provided on the seventh frame side 22c and a second convex portion 24A provided on the seventh frame side 22c or the eighth frame side 22d. Good too.

In the example shown in FIGS. 1 and 2, the width of the second construction member 25 is the same as the length of the lower portion 24a of the second convex portion 24A in the extending direction. However, the width of the second construction member 25 may be wider or narrower than the length of the lower part 24a of the second convex portion 24A in the extending direction. When the width of the second construction member 25 is wider than the length of the lower part 24a of the second convex portion 24A in the extending direction, the second construction member 25 is attached to two adjacent second convex portions 24A via the second base portion 23A. They may be placed astride each other. Here, the "width of the second construction member 25" is the length of the second construction member 25 in the direction perpendicular to the construction direction and the thickness direction of the second construction member 25.

The length of the second construction member 25 in the construction direction may be the same as the length between the second projections 24A in the pair of second projections 24A, or may be longer. The second construction member 25 may be constructed so that there is no slack, or it may be constructed in a slack state.

When a plurality of second construction members 25 are provided, the object to be packed 1 can be held stably. However, depending on the size of the second construction member 25 and the size of the object to be packed 1, the number of the second construction members 25 may be one. The second construction member 25 is not limited to being provided on all the second convex portions 24A. That is, there may be a second convex portion 24A in which the second construction member 25 is not provided.

It is preferable that the second construction member 25 is an elastic body. It is preferable that the tensile modulus of the second construction member 25 is 1.0 MPa or more. As a result, even if excessive force is applied to the first packaging material 10A or the second packaging material 20A in a state where the object to be packed 1 is held between the first construction member 15 and the second construction member 25, the second construction member 15 and the second construction member 25 By bending the member 25, it is possible to prevent excessive force from being applied to the object to be packed 1. The same material as the first construction member 15 can be used for the second construction member 25 . In the example shown in FIGS. 1 and 2, the second construction member 25, like the first construction member 15, has a sheet shape. Like the first construction member 15, each second construction member 25 may be composed of a single sheet, or may be a plurality of members arranged or stacked. When a plurality of members are arranged or overlapped, each member may be parallel to each other, or some members may intersect with each other. The plurality of members may be made of the same material or may be made of different materials. Further, the second construction member 25 may be a mesh-like sheet. The thickness of the second construction member 25 is, for example, 100 μm. The thickness of the second construction member 25 may be uniform throughout, or may vary partially. The thickness of the second construction member 25 may be the same as or different from the thickness of the first construction member 15.

In the example shown in FIG. 2, the second construction member 25 is constructed on the lower surface of the lower part 24a of the second convex portion 24A. The second construction member 25 is bonded to the lower surface of the second convex portion 24A using an adhesive, for example. Note that the second construction member 25 is not limited to being joined to the lower surface of the lower portion 24a of the second convex portion 24A, but may be joined to the upper surface or side surface of the lower portion 24a. Moreover, two or more of the lower surface, side surface, and upper surface of the lower part 24a may be joined. In addition, the "side surface" here refers to the side surface of the side which is not connected to the 2nd side part 24b among the four side surfaces which connect the upper surface and the lower surface of the lower part 24a.

In the package 1000, the first base 13A of the first packaging material 10A and the second protrusion 24A of the second packaging material 20A face each other, and the first protrusion 14A of the first packaging material 10A and the second packaging material It is preferable that the first packaging material 10A and the second packaging material 20A overlap so that the second base part 23A of the packaging material 20A faces each other. This prevents the first member 11A of the first packaging material 10A and the second member 21A of the second packaging material 20A from coming into contact when the object to be packed 1 is held between the first packaging material 10A and the second packaging material 20A. can be suppressed.

In the package 1000, the height from the first base 13A to the lower part 24a of the second protrusion 24A is preferably lower than the height from the first base 13A to the upper part 14a of the first protrusion 14A. As a result, the height from the first base 13A to the lower part 24a of the second convex part 24A is the same as the height from the first base 13A to the upper part 14a of the first convex part 14A. The force with which the member 15 and the second construction member 25 clamp the object 1 to be packed can be increased.

It is preferable that the first packaging material 10A and the second packaging material 20A have the same size and the same shape in plan view. In this way, when the first packaging material 10A and the second packaging material 20A are the same, the member (first packaging material 10A) that holds the object to be packed 1 from below and the member that holds the object to be packed 1 from above It can be used for either member (second packaging material 20A), and costs can be reduced.

(Another example of the first embodiment)
FIG. 7 is a diagram schematically showing another example of the package 1000E according to the first embodiment. FIG. 8 is an exploded perspective view of FIG. 7. The object to be packaged 1 illustrated in FIGS. 7 and 8 is shaded for easy identification. Comparing the package 1000 and the package 1000E, the heights of the first convex portion 14A and the second convex portion 24A of the packaging material in the package 1000E are the same as those of the first convex portion 14A and the second convex portion 24A of the packaging material 100 in the package 1000. The difference is that the height is lower than that of the convex portion 24A, and the other configurations are the same. In the case of the package 1000E, since the packaging material 100E in which the first convex portion 14A and the second convex portion 24A are low in height is used, the package can be made thinner.

Further, the shapes of the first base portion 13B and the second base portion 23B in plan view are both rectangular. However, the shape of the first base 13B and the second base 23B in plan view is not limited to a rectangle, but may be a square. The size of the first base portion 13B and the second base portion 23B in plan view is larger than the size of the object to be packed 1. The thickness of the first base portion 13B and the second base portion 23B is, for example, 3 mm or more and 10 mm or less.

The first convex portion 14B is disposed on the upper surface of the first base portion 13B, and is disposed in a region that does not overlap with the object to be packed 1 in plan view. The first convex portion 14B is provided with a pair of two first convex portions 14B in the lateral direction of the rectangular first base portion 13B.

The shapes of the first convex portion 14B and the second convex portion 24B are rectangular parallelepipeds, as shown in FIG. However, the shapes of the first convex portion 14B and the second convex portion 24B are not limited to this, and may be the first convex portion 14A and the second convex portion 24A as described in the first embodiment.

The first convex portion 14B can be bonded to the first base portion 13B with an adhesive. The first base portion 13B and the first convex portion 14B may be made of the same material or may be made of different materials. The same applies to the second convex portion 24B, in which the material described in the first embodiment can be used as the material for the first base portion 13B.

In the example shown in FIG. 10, two first construction members 15 and two second construction members 25 are provided.

In the package 2000 of the second embodiment, the first member 11B and the second member 21B include the flat first base 13B and the second base 23B. Compared to the case where the member 21A is frame-shaped, the first member 11B and the second member 21B have higher strength against external forces. On the other hand, in the package 1000 or 1000E of the first embodiment, since the first member 11A and the second member 21A are frame-shaped, the first member 11B and the second member 21B described in the second embodiment are The weight can be reduced compared to the case where the first base portion 13B and the second base portion 23B are plate-shaped.

<Third embodiment>
(Package 3000)
FIG. 11 is a perspective view schematically showing a package 3000 according to the third embodiment. FIG. 12 is an exploded perspective view of FIG. 11. The objects to be packaged 1A and 1B shown in FIGS. 11 and 12 are painted out to make them easier to identify.

As shown in FIGS. 11 and 12, the package 3000 includes, in addition to the object to be packed 1 (the first object to be packed 1A), the first packing material 10A, and the second packing material 20A described in the first embodiment, , a second packaged object 1B, and a third packaging material 30A. The third packaging material 30A is constructed over a third member 31A having a third base 33A and at least a pair of third protrusions 34A located below the third base 33A, and a pair of third protrusions 34A. and a third construction member 35.

Thereby, when the second object to be packed 1B is held between the second construction member 25 and the third construction member 35, contact between the second member 21A and the third member 31A can be suppressed.

The first object to be packed 1A is preferably arranged in a region where the first construction member 15 and the second construction member 25 overlap. Thereby, the first object to be packed 1A is stably held. Similarly, it is preferable that the second object to be packed 1B is also arranged in a region where the second construction member 25 and the third construction member 35 overlap.

The package 3000 includes two items 1 to be packed. However, the number of objects to be packed is not limited to this, and three or more objects to be packed can be packed by stacking the packing materials and objects to be packed alternately.

Although an example has been described in which the second upper construction member 25B of the second packaging material 20A is constructed on the pair of second bases 23A, the present invention is not limited thereto. For example, the second member 21A of the second packaging material 20A may further include a pair of convex portions located above the second base portion 23A, and the second upper construction member 25B may be constructed on the pair of convex portions.

(Packing method)
The packaging method according to this embodiment will be explained below. Here, a method for packing a package according to the first embodiment will be described. Similar methods may be adopted for other embodiments.

(Process of preparing the first packaging material 10A)
A first member 11A having a first base portion 13A and at least a pair of first convex portions 14A located above the first base portion 13A, and a first construction member 15 that is constructed over the pair of first convex portions 14A. A first packaging material 10A is prepared. The first packaging material 10A may be prepared by manufacturing it, or may be prepared by purchasing it. The same applies to the second packaging material 20A described later.

(Step of preparing second packaging material 20A)
A second member 21A having a second base portion 23A and at least a pair of second convex portions 24A located below the second base portion 23A; and a second construction member 25 installed over the pair of second convex portions 24A. A second packaging material 20A is prepared. The second packaging material 20A can be the same as the first packaging material 10A.

(Process of placing the object to be packed 1)
The object to be packed 1 is placed on the first packing material 10A so that the object to be packed 1 is held by the first construction member 15.

(Step of placing second packaging material 20A)
The second packing material 20A is placed on the object to be packed 1 with the object to be packed 1 holding the second construction member 25 and the first member 11A and the second member 21A separated from each other.

Through the above steps, a package 1000 in which the object to be packaged 1 is packed can be obtained.

When packing a plurality of objects 1 to be packed, a plurality of packages as described in the first embodiment may be prepared and each package may be stacked. Alternatively, as described in the third embodiment, the first packaging material 10A, the second packaging material 20A, and the third packaging material 30A are the same packaging material, and the packaging material and the object to be packed 1 are alternately arranged. The first packing material 10A, the object to be packed 1A, the second packing material 20A, the second object to be packed 1B, and the third packing material 30A may be stacked in this order.

In the package, the packing materials can be fixed to each other using tape or string, with the object to be packed being held between the packing materials. Thereby, it is possible to maintain the force of the packing material to clamp the object to be packed. Note that after wrapping the package in a bag (for example, a bag having an antistatic function), the packing materials can be fixed to each other using tape or string.

The package can be stored in a transport case.
