[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-205954 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the packaging device described in Patent Document 1 may not have sufficient strength. For example, the lid surface (ceiling piece) may sink.

[0005] The present invention has been made in view of the above problems, and an object of the present invention is to provide a packaging device and a plate-shaped member that can improve strength. [Means for solving the problem]

[0006] A packaging tool according to the present invention is used for packaging an item. The packaging tool includes a plate-shaped member. The plate-shaped member has a reference surface, a first standing surface, an opposing surface, a side surface, and a first support surface. The first standing surface is connected to the reference surface. The first standing surface stands up against the reference surface. The opposing surface is connected to the first standing surface. The opposing surface faces the reference surface. The side surface is connected to the opposing surface. The first support surface is connected to the side surface. The first support surface is in contact with the opposing surface and the reference surface. The first support surface supports the opposing surface against the reference surface.

[0007] In one embodiment, the first support surface faces the side surface.

[0008] In one embodiment, the first support surface contacts the side surface.

[0009] In one embodiment, the first support surface has a first side, a second side, a third side, and a fourth side. The first side is connected to the side surface. The second side is connected to the first side. The second side is located on the reference surface side. The third side is connected to the first side. The third side faces the second side. The third side is located on the opposing surface side. The fourth side is connected to the second side and the third side. The fourth side faces the first side. The second side is inclined with respect to the third side. The distance between the second side and the third side becomes longer with increasing distance from the first side.

[0010] In one embodiment, the plate-shaped member further includes a second support surface that is connected to the side surface and supports the opposing surface via the side surface.

[0011] In one embodiment, the plate-like member further has a second standing surface and an auxiliary support surface. The second standing surface is connected to the reference surface. The second standing surface stands relative to the reference surface. The second standing surface faces the first standing surface. The auxiliary support surface is connected to the opposing surface. The auxiliary support surface is in contact with the reference surface. The auxiliary support surface is in contact with the second standing surface.

[0012] In one embodiment, the plate-shaped member further includes a cover surface that is connected to the second upright surface and covers at least a portion of the opposing surface.

[0013] In one embodiment, the cover surface has a cover main body and a protrusion. The protrusion protrudes from the cover main body. The opposing surface has an insertion port formed therein. The protrusion can be inserted into the insertion port. The opposing surface has a restricting portion. The restricting portion restricts movement of the protrusion when the protrusion is inserted into the insertion port.

[0014] In one embodiment, the socket includes a first portion and two second portions. The first portion extends in a first direction. The two second portions extend in a second direction from both ends of the first portion in the first direction. The second direction intersects with the first direction. The restricting portion is located between the two second portions.

[0015] In one embodiment, the protrusion has a protrusion main body and an overhanging portion. The overhanging portion overhangs from the protrusion main body. The overhanging portion is bendable relative to the protrusion main body. The protrusion is insertable into the insertion port by bending the overhanging portion relative to the protrusion main body. The overhanging portion restricts movement of the protrusion when the protrusion is inserted into the insertion port.

[0016] In one embodiment, the first upright surface has a pair of cut lines and a lead-out portion. The pair of cut lines connect to the socket. The lead-out portion is located between the pair of cut lines.

[0017] In one embodiment, the packaging device further includes a film, the film being attached to the plate-like member.

[0018] In one embodiment, the first support surface abuts against the reference surface via the film.

[0019] In one embodiment, the plate-like member is partitioned via a fold line. The film is attached so as to cover at least a portion of the reference surface. The reference surface has a placement surface and a folding surface. The item is placed on the placement surface. The folding surface is adjacent to the placement surface via the fold line and is foldingable. The item can be placed in the gap between the placement surface and the film. As the folding state of the folding surface relative to the placement surface changes, the film is stretched in contact with the item, so that the item is pressed against the plate-like member.

[0020] The plate-like member according to the present invention is for use in a packaging tool. The packaging tool is used for packaging an article. In an assembled state, the plate-like member comprises a reference surface, a first standing surface, an opposing surface, a side surface, and a first supporting surface. The first standing surface is connected to the reference surface. The first standing surface stands up relative to the reference surface. The opposing surface is connected to the first standing surface. The opposing surface faces the reference surface. The side surface is connected to the opposing surface. The first supporting surface is connected to the side surface. The first supporting surface is in contact with the opposing surface and the reference surface. The first supporting surface supports the opposing surface relative to the reference surface. Effect of the Invention

[0023] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference symbols, and the description will not be repeated. In addition, in the drawings, the X-axis, Y-axis, and Z-axis of a three-dimensional orthogonal coordinate system are appropriately described for ease of understanding. The X-axis and Y-axis are parallel to the horizontal direction, and the Z-axis is parallel to the vertical direction. The positive direction of the Z-axis indicates the vertically upward direction, and the negative direction of the Z-axis indicates the vertically downward direction.

[0024] [Embodiment 1] A packaging device 1 according to a first embodiment of the present invention will be described with reference to Fig. 1(a) and Fig. 1(b). Fig. 1(a) and Fig. 1(b) are schematic perspective views of the packaging device 1 according to the first embodiment of the present invention. Fig. 1(a) shows the packaging device 1 in a state where the cover surface 180 is closed. Fig. 1(b) shows the packaging device 1 in a state where the cover surface 180 is open.

[0025] As shown in Fig. 1(a) and Fig. 1(b), the packaging tool 1 includes a plate 100. The plate 100 is an example of a "plate-like member." The packaging tool 1 is used to pack an item. The packaging tool 1 has a rectangular parallelepiped shape.

[0026] The plate 100 is made of a single piece of cardboard with a thickness of about 5 mm. The plate 100 has a reference surface 110, a first standing surface 120, an opposing surface 130, two side surfaces (side surface 140a and side surface 140b), four first support surfaces (first support surface 150a, first support surface 150b, first support surface 150c, and first support surface 150d), a second standing surface 160, two auxiliary support surfaces (auxiliary support surface 170a and auxiliary support surface 170b), and a cover surface 180.

[0027] In this specification, side surface 140a and side surface 140b may be collectively referred to as side surface 140. Also, in this specification, first supporting surface 150a, first supporting surface 150b, first supporting surface 150c, and first supporting surface 150d may be collectively referred to as first supporting surface 150.

[0028] The reference surface 110 has a rectangular shape. In this embodiment, an article is placed on the reference surface 110.

[0029] The first standing surface 120 is connected to the reference surface 110. More specifically, the first standing surface 120 is connected to the end of the reference surface 110 on the +X direction side. The first standing surface 120 stands upright relative to the reference surface 110. The first standing surface 120 is bent in the +Z direction relative to the reference surface 110. The longitudinal direction of the first standing surface 120 is parallel to the Y axis. The first standing surface 120 is rectangular.

[0030] The facing surface 130 is connected to the first standing surface 120. The facing surface 130 is rectangular. The facing surface 130 is bent in the -X direction with respect to the first standing surface 120. That is, the facing surface 130 is bent inward. The facing surface 130 faces the reference surface 110. The longitudinal direction of the facing surface 130 is parallel to the Y axis. The facing surface 130 has an insertion port 132 formed therein. The insertion port 132 is rectangular. The insertion port 132 is formed at a position where the protrusion 182 described later can be inserted. The length of the insertion port 132 along the Y axis direction is approximately equal to the length of the protrusion 182 along the Y axis direction. Therefore, the protrusion 182 can be inserted into the insertion port 132.

[0031] The side surface 140 is connected to the opposing surface 130. More specifically, the side surface 140a is connected to the end of the opposing surface 130 in the -Y direction. The side surface 140b is connected to the end of the opposing surface 130 in the +Y direction. The side surfaces 140a and 140b are rectangular. The side surface 140a is bent in the -Z direction with respect to the opposing surface 130. The side surface 140b is bent in the -Z direction with respect to the opposing surface 130. That is, the side surfaces 140a and 140b are bent downward. The longitudinal direction of the side surface 140a and the longitudinal direction of the side surface 140b are parallel to the X-axis.

[0032] The first support surface 150 is connected to the side surface 140. More specifically, the first support surface 150a is connected to the end of the side surface 140a in the +X direction. The first support surface 150b is connected to the end of the side surface 140b in the +X direction. The first support surface 150c is connected to the end of the side surface 140a in the -X direction. The first support surface 150d is connected to the end of the side surface 140b in the -X direction. The first support surface 150 contacts the opposing surface 130 and the reference surface 110. More specifically, each of the first support surface 150a, the first support surface 150b, the first support surface 150c, and the first support surface 150d contacts the opposing surface 130 and the reference surface 110. The first support surface 150 supports the opposing surface 130 against the reference surface 110. The first support surface 150 is rectangular.

[0033] The first supporting surface 150 faces the first standing surface 120. More specifically, the first supporting surface 150a faces the first standing surface 120. The first supporting surface 150b faces the first standing surface 120. The first supporting surface 150 contacts the first standing surface 120. More specifically, the first supporting surface 150a contacts the first standing surface 120. The first supporting surface 150b contacts the first standing surface 120.

[0034] The second standing surface 160 is connected to the reference surface 110. More specifically, the second standing surface 160 is connected to an end of the reference surface 110 on the -X direction side. That is, the second standing surface 160 is connected to an end of the reference surface 110 on the opposite side in the X axis direction to the end of the reference surface 110 to which the first standing surface 120 is connected. The second standing surface 160 stands upright relative to the reference surface 110. The second standing surface 160 is bent in the +Z direction relative to the reference surface 110. The second standing surface 160 faces the first standing surface 120. The longitudinal direction of the second standing surface 160 is parallel to the Y axis. The second standing surface 160 is rectangular.

[0035] The auxiliary support surface 170 is connected to the opposing surface 130. More specifically, the auxiliary support surface 170a and the auxiliary support surface 170b are each connected to an end of the opposing surface 130 in the X-side direction. The auxiliary support surface 170 is in contact with the reference surface 110. More specifically, the auxiliary support surface 170a and the auxiliary support surface 170b are each in contact with the reference surface 110. The auxiliary support surface 170 supports the opposing surface 130 with respect to the reference surface 110. The auxiliary support surface 170 is in contact with the second standing surface 160. More specifically, the auxiliary support surface 170a and the auxiliary support surface 170b are each in contact with the second standing surface 160.

[0036] The cover surface 180 is connected to the second standing surface 160. The cover surface 180 covers at least a portion of the opposing surface 130. In this embodiment, the cover surface 180 covers the entire opposing surface 130. The cover surface 180 has a cover main body portion 181 and a protrusion portion 182. The cover main body portion 181 is rectangular. The protrusion portion 182 protrudes from the cover main body portion 181. The protrusion portion 182 is rectangular. By inserting the protrusion portion 182 into the insertion port 132, the cover surface 180 is fixed to the opposing surface 130. As a result, the cover surface 180 can be closed.

[0037] The first support surface 150 will be further described with reference to Fig. 2. Fig. 2 is an enlarged view of the vicinity of the first support surface 150a shown in Fig. 1(a). In Fig. 2, a boundary 42 indicates the boundary between the side surface 140a and the opposing surface 130.

[0038] As shown in FIG. 2, the first support surface 150a has a first side 151, a second side 152, a third side 153, and a fourth side 154. The second side 152 and the third side 153 extend in the Y-axis direction. The second side 152 and the third side 153 face each other. The first side 151 and the fourth side 154 extend in the Z-axis direction. The first side 151 and the fourth side 154 face each other. The first side 151 connects to the side surface 140a. The second side 152 connects to the first side 151. The second side 152 is located on the reference surface 110 side. The third side 153 connects to the first side 151. The third side 153 is located on the opposing surface 130 side. The fourth side 154 connects to the second side 152 and the third side 153. The first side 151 and the fourth side 154 are parallel to each other. The second side 152 and the third side 153 are parallel to each other. The distance between the second side 152 and the third side 153 is constant.

[0039] 1(a) to 2, the first support surface 150a contacts the opposing surface 130 and the reference surface 110. Therefore, even if a force is applied in the direction D1, the first support surface 150a can prevent the opposing surface 130 from being recessed in the direction D1. As a result, the strength of the packaging tool 1 can be improved.

[0040] Moreover, the first support surface 150a contacts the opposing surface 130 and the reference surface 110. Therefore, even if a force is applied in the direction D2, the first support surface 150a can prevent the opposing surface 130 from being recessed in the direction D2. As a result, the strength of the packaging tool 1 can be improved.

[0041] Moreover, if the first support surface 150a does not exist, when a force is applied in the direction D3, the side surface 140a rotates in the direction D4 with the boundary 42 as an axis. In other words, if the first support surface 150a does not exist, when a force is applied in the direction D3, the lower end of the side surface 140a may be recessed in the direction D3. On the other hand, as shown in FIG. 2, when the first support surface 150a exists, even if a force is applied in the direction D3, the first support surface 150a is in contact with the opposing surface 130 and the reference surface 110, so that the third edge 153 of the first support surface 150a can prevent the side surface 140a from rotating in the direction D4. Therefore, even if a force is applied in the direction D3, the lower end of the side surface 140a can be prevented from recessing in the direction D3. As a result, the strength of the packaging tool 1 can be improved.

[0042] Moreover, if the first support surface 150a does not exist, when a force is applied in the direction D5, the side surface 140a rotates in the direction D6 with the boundary 42 as an axis. In other words, if the first support surface 150a does not exist, when a force is applied in the direction D5, the lower end of the side surface 140a may protrude in the direction D5. On the other hand, as shown in FIG. 2, when the first support surface 150a exists, even if a force is applied in the direction D5, the first support surface 150a is in contact with the opposing surface 130 and the reference surface 110, so that the second edge 152 of the first support surface 150a can suppress the side surface 140a from rotating in the direction D6. Therefore, even if a force is applied in the direction D5, the lower end of the side surface 140a can be suppressed from protruding in the direction D5. As a result, the strength of the packaging tool 1 can be improved.

[0043] The plate 100 according to the first embodiment of the present invention will be further described with reference to Figures 1(a), 1(b) and 3. Figure 3 is a development view of the plate 100 according to the first embodiment of the present invention.

[0044] As shown in FIG. 3, the plate 100 is in the form of a sheet. The plate 100 is a member for a packaging tool used to pack an article. The packaging tool 1 shown in FIG. 1(a) is assembled by assembling the plate 100. Therefore, the plate 100, in the assembled state, constitutes a reference surface 110, a first standing surface 120, an opposing surface 130, two side surfaces (side surface 140a and side surface 140b), four first support surfaces (first support surface 150a, first support surface 150b, first support surface 150c, and first support surface 150d), a second standing surface 160, two auxiliary support surfaces (auxiliary support surface 170a and auxiliary support surface 170b), and a cover surface 180.

[0045] Next, with reference to Figures 1(a), 1(b) and 4(a) to 6(b), a method of assembling the packaging tool 1 will be described. Figures 4(a) to 6(b) are perspective views showing a method of assembling the packaging tool 1.

[0046] From the state shown in Fig. 4(a), the side surface 140a is bent in the +Z direction as shown in Fig. 4(b), and the side surface 140b is bent in the +Z direction.

[0047] Next, from the state shown in Fig. 4(b), as shown in Fig. 5(a), first support surface 150a is bent in the +Y direction. First support surface 150b is bent in the -Y direction. First support surface 150c is bent in the +Y direction. First support surface 150d is bent in the -Y direction.

[0048] Next, from the state shown in FIG. 5(a), the auxiliary support surface 170a and the auxiliary support surface 170b are bent in the +Z direction as shown in FIG. 5(b).

[0049] Next, from the state shown in Fig. 5(b), as shown in Fig. 6(a), the opposing surface 130 is bent in the +Z direction, and then the first standing surface 120 is bent in the +Z direction. As a result, as described with reference to Figs. 1(a) and 1(b), the first supporting surface 150a, the first supporting surface 150b, the first supporting surface 150c, and the first supporting surface 150d come into contact with the opposing surface 130 and the reference surface 110.

[0050] Next, from the state shown in FIG. 6(a), the second standing surface 160 is bent in the +Z direction as shown in FIG. 6(b).

[0051] Next, from the state shown in Fig. 6(b), the protrusion 182 is bent in the +X direction, and then the cover surface 180 is bent in the +X direction, thereby inserting the protrusion 182 into the insertion port 132. By inserting the protrusion 182 into the insertion port 132, the cover surface 180 is fixed to the opposing surface 130. As a result, the cover surface 180 can be closed as shown in Fig. 1(a).

[0052] As described above with reference to Fig. 1 to Fig. 6(b), the first support surface 150 contacts the opposing surface 130 and the reference surface 110. The first support surface 150 supports the opposing surface 130 with respect to the reference surface 110. Therefore, the strength of the packaging tool 1 can be improved.

[0053] Additionally, the auxiliary support surface 170 is connected to the opposing surface 130 and is in contact with the reference surface 110. Therefore, the strength of the packaging tool 1 can be improved.

[0054] [Embodiment 2] With reference to Fig. 7(a) and Fig. 7(b), the packaging tool 1 according to the second embodiment of the present invention will be described. Fig. 7(a) and Fig. 7(b) are schematic perspective views of the packaging tool 1 according to the second embodiment of the present invention. Fig. 7(a) shows the packaging tool 1 in a state where the cover surface 180 is closed. Fig. 7(b) shows the packaging tool 1 in a state where the cover surface 180 is open. The packaging tool 1 according to the second embodiment differs from the packaging tool 1 according to the first embodiment in that the plate 100 has the second support surface 190a and the second support surface 190b. Below, the differences between the second embodiment and the first embodiment will be mainly described.

[0055] As shown in Figures 7(a) and 7(b), the plate 100 has a reference surface 110, a first standing surface 120, an opposing surface 130, two side surfaces (side surface 140a and side surface 140b), four first support surfaces (first support surface 150a, first support surface 150b, first support surface 150c and first support surface 150d), a second standing surface 160, two auxiliary support surfaces (auxiliary support surface 170a and auxiliary support surface 170b), a cover surface 180, and further two second support surfaces (second support surface 190a and second support surface 190b).

[0056] In this specification, the second support surface 190a and the second support surface 190b may be collectively referred to as the second support surface 190.

[0057] The second support surface 190 is connected to the side surface 140. More specifically, the second support surface 190a is connected to the end of the side surface 140a in the -Z direction. The second support surface 190b is connected to the end of the side surface 140b in the -Z direction. The second support surface 190a and the second support surface 190b are rectangular. The second support surface 190a is bent in the +Y direction with respect to the side surface 140a. The second support surface 190b is bent in the -Y direction with respect to the side surface 140b. That is, the second support surface 190a and the second support surface 190b are bent inward. The longitudinal direction of the second support surface 190a and the longitudinal direction of the second support surface 190b are parallel to the X-axis. The longitudinal direction of the second support surface 190 is parallel to the longitudinal direction of the side surface 140. Specifically, the longitudinal direction of the second support surface 190a is parallel to the longitudinal direction of the side surface 140a, and the longitudinal direction of the second support surface 190b is parallel to the longitudinal direction of the side surface 140b.

[0058] The second support surface 190 supports the opposing surface 130 via the side surface 140. More specifically, the second support surface 190a supports the opposing surface 130 via the side surface 140a. The second support surface 190b supports the opposing surface 130 via the side surface 140b. This further improves the strength of the opposing surface 130. As a result, the strength of the packaging tool 1 can be improved.

[0059] The plate 100 according to the first embodiment of the present invention will be further described with reference to Figures 7(a), 7(b) and 8. Figure 8 is a development view of the plate 100 according to the second embodiment of the present invention.

[0060] As shown in FIG. 8, the plate 100 is in the form of a sheet. The plate 100 is a member for a packaging tool used to pack an article. The packaging tool 1 shown in FIG. 7(a) is assembled by assembling the plate 100. Therefore, in the assembled state, the plate 100 constitutes a reference surface 110, a first standing surface 120, an opposing surface 130, two side surfaces (side surface 140a and side surface 140b), four first support surfaces (first support surface 150a, first support surface 150b, first support surface 150c, and first support surface 150d), a second standing surface 160, two auxiliary support surfaces (auxiliary support surface 170a and auxiliary support surface 170b), a cover surface 180, and two second support surfaces (second support surface 190a and second support surface 190b).

[0061] Next, a method of assembling the packaging device 1 will be described with reference to Fig. 7 and Fig. 9(a) to Fig. 11(b). Fig. 9(a) to Fig. 11(b) are perspective views showing a method of assembling the packaging device 1.

[0062] From the state shown in Fig. 9(a), as shown in Fig. 9(b), the side surface 140a is bent in the +Z direction, and then the second support surface 190a is bent in the +Y direction. Also, the side surface 140b is bent in the +Z direction, and then the second support surface 190b is bent in the -Y direction.

[0063] Next, from the state shown in Fig. 9(b), as shown in Fig. 10(a), first support surface 150a is bent in the +Y direction. First support surface 150b is bent in the -Y direction. First support surface 150c is bent in the +Y direction. First support surface 150d is bent in the -Y direction.

[0064] Next, from the state shown in FIG. 10(a), the auxiliary support surface 170a and the auxiliary support surface 170b are bent in the +Z direction as shown in FIG. 10(b).

[0065] 10(b), the opposing surface 130 is bent in the +Z direction, and then the first standing surface 120 is bent in the +Z direction, as shown in FIG. 11(a). As a result, the second supporting surface 190a and the second supporting surface 190b come into contact with the reference surface 110.

[0066] Next, from the state shown in FIG. 11(a), the second standing surface 160 is bent in the +Z direction as shown in FIG. 11(b).

[0067] Next, from the state shown in Fig. 11(b), the protrusion 182 is bent in the +X direction, and then the cover surface 180 is bent in the +X direction, thereby inserting the protrusion 182 into the insertion port 132. By inserting the protrusion 182 into the insertion port 132, the cover surface 180 is fixed to the opposing surface 130. As a result, the cover surface 180 can be closed as shown in Fig. 7(a).

[0068] As described above with reference to Fig. 7 to Fig. 11(b), the second support surface 190 supports the opposing surface 130 via the side surface 140. This makes it possible to further improve the strength of the opposing surface 130. As a result, it is possible to further improve the strength of the packaging device 1.

[0069] [Embodiment 3] The packaging tool 1 according to the third embodiment of the present invention will be described with reference to Fig. 12. Fig. 12 is a schematic perspective view of the packaging tool 1 according to the third embodiment of the present invention. The packaging tool 1 according to the third embodiment differs from the packaging tool 1 according to the second embodiment in that the plate 100 does not have two auxiliary support surfaces 170 and that the plate 100 does not have a cover surface 180. The following mainly describes the differences between the third embodiment and the second embodiment.

[0070] As shown in Fig. 12, the board 100 has a reference surface 110, a first standing surface 120, an opposing surface 130, two side surfaces (side surface 140a and side surface 140b), four first support surfaces (first support surface 150a, first support surface 150b, first support surface 150c, and first support surface 150d), a second standing surface 160, and two second support surfaces (second support surface 190a and second support surface 190b). In this embodiment, the board 100 does not have a cover surface 180. Therefore, in this embodiment, the opposing surface 130 constitutes the top surface.

[0071] In the present embodiment as well, the first support surface 150 contacts the opposing surface 130 and the reference surface 110. The first support surface 150 supports the opposing surface 130 with respect to the reference surface 110. Therefore, the strength of the packaging tool 1 can be improved.

[0072] Furthermore, the second support surface 190 supports the opposing surface 130 via the side surface 140. This makes it possible to further improve the strength of the opposing surface 130. As a result, the strength of the packaging tool 1 can be further improved.

[0073] The plate 100 according to the first embodiment of the present invention will be further described with reference to Figures 12 and 13. Figure 13 is a development view of the plate 100 according to the third embodiment of the present invention.

[0074] As shown in Fig. 13, the plate 100 is in the form of a sheet. The plate 100 is a member for a packaging tool used to pack an item. The packaging tool 1 shown in Fig. 12 is assembled by assembling the plate 100. Therefore, in the assembled state, the plate 100 forms a reference surface 110, a first standing surface 120, an opposing surface 130, two side surfaces (side surface 140a and side surface 140b), four first support surfaces (first support surface 150a, first support surface 150b, first support surface 150c, and first support surface 150d), a second standing surface 160, and two second support surfaces (second support surface 190a and second support surface 190b).

[0075] The second upright surface 160 has an insertion portion 162. The insertion portion 162 is trapezoidal in shape.

[0076] Next, a method of assembling the packaging tool 1 will be described with reference to Fig. 12 and Fig. 14(a) to Fig. 16. Fig. 14(a) to Fig. 16 are perspective views showing a method of assembling the packaging tool 1.

[0077] 14(a), as shown in FIG 14(b), the side surface 140a is bent in the +Z direction, and then the second support surface 190a is bent in the +Y direction. Also, the side surface 140b is bent in the +Z direction, and then the second support surface 190b is bent in the -Y direction.

[0078] Next, from the state shown in Fig. 14(b), as shown in Fig. 15(a), first support surface 150a is bent in the +Y direction. First support surface 150b is bent in the -Y direction. First support surface 150c is bent in the +Y direction. First support surface 150d is bent in the -Y direction.

[0079] Next, from the state shown in FIG. 15(a), the facing surface 130 is bent in the +Z direction as shown in FIG. 15(b).

[0080] 15(b), the first standing surface 120 is bent in the +Z direction as shown in Fig. 16. As a result, the second supporting surface 190a and the second supporting surface 190b come into contact with the reference surface 110.

[0081] 16, the insertion portion 162 is folded in the +Z direction, and then the second standing surface 160 is folded in the +Z direction, so that the insertion portion 162 is inserted into the lower portion of the opposing surface 130. As a result, the packaging tool 1 can be assembled as shown in FIG.

[0082] 12 to 16, in this embodiment as well, similarly to the second embodiment, the second support surface 190 supports the opposing surface 130 via the side surface 140. Therefore, the strength of the opposing surface 130 can be further improved. As a result, the strength of the packaging tool 1 can be further improved.

[0083] [Embodiment 4] The packaging tool 1 according to the fourth embodiment of the present invention will be described with reference to Figs. 17 and 18. Fig. 17 is a development view of the packaging tool 1 according to the fourth embodiment of the present invention. Fig. 18 is a schematic perspective view of the packaging tool 1 according to the fourth embodiment of the present invention. In Fig. 17, the film 30 is indicated by a two-dot chain line to make the drawing easier to see. The packaging tool 1 according to the fourth embodiment differs from the packaging tool 1 according to the first embodiment in that the packaging tool 1 includes the film 30 and that the plate 100 is provided with a folding line 21. The following mainly describes the differences between the fourth embodiment and the first embodiment.

[0084] As shown in Fig. 17 and Fig. 18, the packaging tool 1 further includes a film 30 in addition to a plate 100. As shown in Fig. 18, in this embodiment, the film 30 is cylindrical. The film 30 is attached to the plate 100. More specifically, the film 30 is wrapped around the plate 100.

[0085] In this embodiment, the packaging tool 1 is configured by combining a film 30 and, for example, a cardboard plate 100. The packaging tool 1 can fix an object in a fixed position by pressing the object against the plate 100 with the film 30. When the plate 100 is in a folded state, an object can be placed in a gap that expands between the contact surface of the plate 100 and the film 30. As the folded state of the plate 100 changes, the film 30 is stretched and the object can be fixed by the film 30.

[0086] 17, the plate 100 is provided with folding lines 21. The folding lines 21 are formed, for example, by pressing a so-called creasing roller or creasing blade against the plate 100. The folding lines 21 may be perforated.

[0087] The folding line 21 is arranged parallel to the X-axis. The folding line 21 extends across the reference surface 110, the first standing surface 120, the opposing surface 130, the second standing surface 160, the auxiliary support surface 170b, and the cover surface 180. Therefore, the plate 100 can be easily folded so that the end portion on the +Y direction side is displaced upward about the folding line 21. In this embodiment, the folding line 21 is offset toward the +Y direction side from the center in the Y-axis direction of the plate 100. In other words, the folding line 21 is located at a position shifted from the center of the plate 100.

[0088] The reference surface 110 has an arrangement surface 111 and a folding surface 112. A folding line 21 is disposed between the arrangement surface 111 and the folding surface 112. In other words, the arrangement surface 111 and the folding surface 112 are partitioned via the folding line 21. The arrangement surface 111 is disposed on the -Y direction side of the reference surface 110, and the folding surface 112 is disposed on the +Y direction side of the reference surface 110.

[0089] An article is placed on the placement surface 111. The folding surface 112 is adjacent to the placement surface 111 via a folding line 21. The folding surface 112 is foldable. More specifically, the reference surface 110 is foldable such that the folding surface 112 is foldable at the folding line 21 relative to the placement surface 111.

[0090] The film 30 is, for example, a polyethylene film having elasticity (flexibility). The film 30 is colorless and transparent, but is not limited thereto, and may be so-called translucent or opaque, or may be colored.

[0091] The film 30 is attached so as to cover at least a part of the reference surface 110. In this embodiment, the film 30 is attached so as to cover the entire reference surface 110. In detail, the film 30 is arranged so as to mainly surround the reference surface 110, the second standing surface 160, and the cover surface 180 of the plate 100. The film 30 is arranged so that the width direction (direction perpendicular to the circumferential direction) of the cylindrical film 30 is the Y-axis direction. In other words, the film 30 is wrapped around the plate 100 so that the folding line 21 passes through the inside of the tube formed by the film 30.

[0092] The film 30 may be attached to the plate 100 by various methods. For example, the film 30 is attached to the plate 100 by passing the plate 100 through the inside of the film 30 that has been formed in advance into a ring shape. Alternatively, the film 30 is attached to the plate 100 by wrapping the film 30 around the plate 100 at least once using a band wrapping machine or the like and bonding the films 30 together. With the film 30 attached to the plate 100, the plate 100 can be folded at the folding lines 21.

[0093] Next, a method for arranging an article 50 using the packaging tool 1 will be described with reference to Figs. 18 to 21. Figs. 19(a) to 19(c) are schematic cross-sectional views taken along line XIX-XIX in Fig. 18. Figs. 20 and 21 are schematic perspective views of the packaging tool 1 according to a fourth embodiment of the present invention. The article is fixed using the packaging tool 1 by following steps S11, S12, and S13 in this order from top to bottom in Figs. 19(a) to 19(c).

[0094] As shown in Fig. 19(a), the packaging tool 1 in the unfolded state is in the shape of a flat plate (S11). From this state, as shown by the upward arrow in the figure, the plate 100 is folded at the folding line 21 to bring the folding surface 112 closer to the placement surface 111, resulting in a folded state (folding step) (see Fig. 20).

[0095] Next, with the plate 100 in the folded state, the article 50 is placed in the gap A between the placement surface 111 and the film 30 (S12; placement step). In this manner, the packaging tool 1 is brought into a state in which the folding surface 112 is folded relative to the placement surface 111 at the folding line 21 (hereinafter, sometimes referred to as the folded state). When the packaging tool 1 is in the folded state, the article 50 can be placed in the gap A between the film 30 and the upper surface of the plate 100.

[0096] Thereafter, as indicated by the downward arrow in the figure, the folded surface 112 is unfolded relative to the placement surface 111 to assume an unfolded state (S13). This causes the film 30 to be stretched in a state of contact with the upper portion of the article 50. This causes the article 50 to be pressed against the plate 100 (unfolding step).

[0097] FIG. 21 is a perspective view showing the packaging device 1 in an unfolded state after packaging.

[0098] 21, when the unfolding step is performed, the length of a straight line connecting the front end and rear end of the plate 100, the fold of the folding line 21, and the top of the article 50 in a side view becomes longer than in the initial unfolded state because the article 50 is placed thereon. The film 30 is stretched slightly while in contact with the top of the article 50. Therefore, the film 30 presses the article 50 against the plate 100. In this manner, the article 50 can be fixed to the plate 100.

[0099] As shown in FIG. 21, after the article 50 is fixed to the board 100, the package 1 is assembled as described with reference to FIGS. 4(a) to 6(b), thereby packaging the article 50.

[0100] In this embodiment, the first support surface 150 abuts against the reference surface 110 via the film 30. Therefore, the film 30 is pressed down by the first support surface 150. Therefore, the force with which the film 30 presses the article 50 against the plate 100 can be strengthened. As a result, it is possible to suppress the article 50 from shifting.

[0101] In the packaging tool 1 described with reference to Figs. 17 to 21, the film 30 is arranged so as to mainly surround the reference surface 110, the second standing surface 160, and the cover surface 180 of the plate 100, but the present invention is not limited to this. Fig. 22 is a development view of the packaging tool 1 according to a modified example of the fourth embodiment of the present invention. As shown in Fig. 22, the film 30 may be arranged so as to mainly surround the reference surface 110 and the second standing surface 160 of the plate 100.

[0102] [Embodiment 5] With reference to Fig. 23(a) and Fig. 23(b), the packaging tool 1 according to the fifth embodiment of the present invention will be described. Fig. 23(a) and Fig. 23(b) are schematic perspective views of the packaging tool 1 according to the fifth embodiment of the present invention. Fig. 23(a) shows the packaging tool 1 in a state where the cover surface 180 is closed. Fig. 23(b) shows the packaging tool 1 in a state where the cover surface 180 is open. The packaging tool 1 according to the fifth embodiment is different from the packaging tool 1 according to the first embodiment in that the shape of the first support surface 150 (the first support surface 150a, the first support surface 150b, the first support surface 150c, and the first support surface 150d) is different, the way in which the cover surface 180 is closed is different, and an opening 136 is formed in the opposing surface 130. Hereinafter, the differences between the fifth embodiment and the first embodiment will be mainly described.

[0103] As shown in Figures 23(a) and 23(b), the plate 100 has a reference surface 110, a first standing surface 120, an opposing surface 130, two side surfaces (side surface 140a and side surface 140b), four first support surfaces (first support surface 150a, first support surface 150b, first support surface 150c, and first support surface 150d), a second standing surface 160, two auxiliary support surfaces (auxiliary support surface 170a and auxiliary support surface 170b), and a cover surface 180. Note that in Figures 23(a) and 23(b), the first support surface (first support surface 150a, first support surface 150b, first support surface 150c, and first support surface 150d) and the two auxiliary support surfaces (auxiliary support surface 170a and auxiliary support surface 170b) are hidden and cannot be seen.

[0104] The cover surface 180 has a cover main body portion 181 and a protrusion portion 182. In this embodiment, the protrusion portion 182 has a protrusion main body portion 1822 and overhanging portions (overhanging portions 1824a and 1824b). In this specification, the overhanging portions 1824a and 1824b may be collectively referred to as overhanging portions 1824. The overhanging portions 1824 overhang from the protrusion main body portion 1822. The overhanging portions 1824 can be bent relative to the protrusion main body portion 1822. The protrusion portion 182 can be inserted into the insertion port 132 by bending the overhanging portions 1824 relative to the protrusion main body portion 1822.

[0105] The opposing surface 130 is formed with a plug 132. In this embodiment, the plug 132 includes a first portion 1322 and two second portions (the second portion 1324a and the second portion 1324b). In this specification, the second portion 1324a and the second portion 1324b may be collectively referred to as the second portion 1324. The first portion 1322 extends in a first direction (Y-axis direction). The first direction is parallel to the direction in which the first standing surface 120 extends. The second portion 1324 extends in a second direction (X-axis direction) from both ends of the first portion 1322 in the first direction. In detail, the second portion 1324a extends in the -X direction from an end portion of the first portion 1322 on the -Y direction side. The second portion 1324b extends in the -X direction from an end portion of the first portion 1322 on the +Y direction side. The second direction intersects with the first direction. In this embodiment, the second direction is perpendicular to the first direction. The protrusion 182 can be inserted into the insertion port 132. More specifically, the protrusion main body 1822 can be inserted into the first portion 1322. The protrusion 1824a can be inserted into the second portion 1324a. The protrusion 1824b can be inserted into the second portion 1324b. The protrusion 1824 restricts the movement of the protrusion 182 when the protrusion 182 is inserted into the insertion port 132. The restriction of the movement of the protrusion 182 by the protrusion 1824 will be described later with reference to FIG. 30(b).

[0106] The opposing surface 130 has a restricting portion 134. The restricting portion 134 is rectangular. The restricting portion 134 is located between two second portions (second portion 1324a and second portion 1324b). The restricting portion 134 restricts movement of the protrusion 182 when the protrusion 182 is inserted into the insertion port 132. The restriction of the movement of the protrusion 182 by the restricting portion 134 will be described later with reference to FIG. 30(a).

[0107] An opening 136 is further formed in the facing surface 130. The opening 136 is substantially rectangular. The corners of the opening 136 are rounded. By forming the opening 136, when the cover surface 180 is opened, the article packed in the packaging tool 1 can be visually confirmed.

[0108] The first upright surface 120 has a pair of cut lines (cut lines 122a and 122b) and a pull-out portion 124. In this specification, the cut lines 122a and 122b may be collectively referred to as cut lines 122. The cut lines 122a and 122b connect to the socket 132. The cut lines 122a and 122b are, for example, perforations. The pull-out portion 124 is located between the pair of cut lines 122 (cut lines 122a and 122b). The pull-out portion 124 can be pulled out to the front side (+X direction side) by tearing both ends of the pull-out portion 124 in the Y-axis direction along the cut lines 122a and 122b. The upper end of the pull-out portion 124 protrudes further than the rest of the first upright surface 120. Therefore, it is easy to pull out the pull-out portion 124 by holding the tip of the pull-out portion 124.

[0109] The plate 100 according to the fifth embodiment of the present invention will be further described with reference to Figures 23(a), 23(b) and 24. Figure 24 is a development view of the plate 100 according to the fifth embodiment of the present invention.

[0110] As shown in FIG. 24, the plate 100 is in the form of a sheet. The plate 100 is a member for a packaging tool used to pack an article. The packaging tool 1 shown in FIG. 23(a) is assembled by assembling the plate 100. Therefore, in the assembled state, the plate 100 constitutes a reference surface 110, a first standing surface 120, an opposing surface 130, two side surfaces (side surface 140a and side surface 140b), four first support surfaces (first support surface 150a, first support surface 150b, first support surface 150c, and first support surface 150d), a second standing surface 160, two auxiliary support surfaces (auxiliary support surface 170a and auxiliary support surface 170b), and a cover surface 180.

[0111] The first support surface 150a, the first support surface 150b, the first support surface 150c, and the first support surface 150d are substantially trapezoidal in shape. The second side 152 is inclined with respect to the third side 153. The distance between the second side 152 and the third side 153 increases with increasing distance from the first side 151.

[0112] Next, a method of assembling the packaging tool 1 will be described with reference to Fig. 23 and Fig. 25(a) to Fig. 30(b). Fig. 25(a) to Fig. 29 are perspective views showing a method of assembling the packaging tool 1. Fig. 30(a) is a schematic cross-sectional view taken along line XXXA-XXXA in Fig. 29. Fig. 30(b) is a top view of the vicinity of the insertion port 132, the restricting portion 134, and the protruding portion 182.

[0113] From the state shown in Fig. 25(a), the side surface 140a is bent in the +Z direction as shown in Fig. 25(b), and the side surface 140b is bent in the +Z direction.

[0114] Next, from the state shown in Fig. 25(b), as shown in Fig. 26(a), first support surface 150a is bent in the +Y direction. First support surface 150b is bent in the -Y direction. First support surface 150c is bent in the +Y direction. First support surface 150d is bent in the -Y direction.

[0115] Next, from the state shown in FIG. 26(a), the auxiliary support surface 170a and the auxiliary support surface 170b are bent in the +Z direction as shown in FIG. 26(b).

[0116] 26(b), the opposing surface 130 is bent in the +Z direction, and then the first standing surface 120 is bent in the +Z direction, as shown in FIG. 27(a). As a result, the first supporting surface 150a, the first supporting surface 150b, the first supporting surface 150c, and the first supporting surface 150d come into contact with the opposing surface 130 and the reference surface 110.

[0117] Next, from the state shown in FIG. 27(a), the second standing surface 160 is bent in the +Z direction as shown in FIG. 27(b).

[0118] Next, from the state shown in FIG. 27(b), the protruding portion 1824a is bent in the +X direction as shown in FIG. 28(a).

[0119] Next, from the state shown in FIG. 28(a), the protrusion main body 1822 is bent in the +X direction as shown in FIG. 28(b).

[0120] Next, by bending cover surface 180 in the +X direction, protrusion 182 is inserted into socket 132. More specifically, protrusion main body 1822 of protrusion 182 is passed through first portion 1322 of socket 132, protrusion 1824a of protrusion 182 is passed through second portion 1324a of socket 132, and protrusion 1824b of protrusion 182 is passed through second portion 1324b of socket 132, and protrusion 1824b of protrusion 182 is passed through second portion 1324b of socket 132, and protrusion 1824b of protrusion 182 is inserted into socket 132.

[0121] When the protrusion 182 is inserted into the insertion port 132, as shown in FIG. 30(a), the tip of the restricting portion 134 comes into contact with the protrusion main body portion 1822. Therefore, with the protrusion 182 inserted into the insertion port 132, the restricting portion 134 restricts the upward movement of the protrusion 182. This makes it possible to prevent the protrusion 182 from coming out of the insertion port 132. As a result, the cover surface 180 is firmly fixed to the opposing surface 130. Therefore, the cover surface 180 can be closed as shown in FIG. 29 without using tape or glue.

[0122] Also, when the protrusion 182 is inserted into the insertion port 132, the overhanging portion 1824a and the overhanging portion 1824b return to the open state due to the restoring force of the cardboard as shown in FIG. 29 and FIG. 30(b). Therefore, the overhanging portion 1824a is located outside (-Y direction side) the second part 1324a of the insertion port 132. Also, the overhanging portion 1824b is located outside (+Y direction side) the second part 1324b of the insertion port 132. Therefore, when the overhanging portion 1824 is inserted into the insertion port 132, the overhanging portion 1824 restricts the upward movement of the protrusion 182. Therefore, it is possible to prevent the protrusion 182 from coming out of the insertion port 132. As a result, the cover surface 180 is firmly fixed to the facing surface 130. Therefore, it is possible to close the cover surface 180 as shown in FIG. 29 without using tape or glue.

[0123] When the cover surface 180 is opened, both ends of the pull-out portion 124 in the Y-axis direction are torn along the cut lines 122a and 122b, and the pull-out portion 124 is pulled out toward the front (+X direction). This allows the protrusion 182 to be exposed. The protrusion 182 can be passed through the insertion port 132 and pulled up (+Z direction). As a result, the cover surface 180 can be opened.

[0124] The first support surface 150 will be further described with reference to Fig. 31. Fig. 31 is an enlarged view of the vicinity of the first support surface 150a.

[0125] As described with reference to FIG. 24, the second side 152 is inclined with respect to the third side 153. The distance between the second side 152 and the third side 153 becomes longer as it moves away from the first side 151. Therefore, as shown in FIG. 31, the second side 152 comes into contact with the reference surface 110, so that the first side 151 is inclined toward the inside (+Y direction side) of the packaging tool 1 with respect to the Z axis direction. Therefore, in conjunction with the first support surface 150a, the side surface 140a moves so as to be inclined toward the inside (+Y direction side) of the packaging tool 1 with respect to the Z axis direction. As a result, the lower end 149 of the side surface 140a is disposed inside the end 119 on the -Y direction side of the reference surface 110. The side surface 140a, which is bent with respect to the opposing surface 130, tends to spread outward due to the restoring force of the cardboard. As a result, a gap is likely to be generated between the lower end 149 of the side surface 140a and the end 119 on the -Y direction side of the reference surface 110. However, in this embodiment, the first support surface 150 causes the lower end 149 of the side surface 140a to be disposed more inward than the end 119 on the -Y direction side of the reference surface 110. As a result, it is possible to suppress the occurrence of a gap between the lower end 149 of the side surface 140a and the end 119 on the -Y direction side of the reference surface 110. Since the first support surface 150c has a similar configuration to the first support surface 150a, the lower end 149 of the side surface 140a is disposed more inward than the end 119 on the Y axis direction of the reference surface 110 in conjunction with the first support surface 150c. Similarly, the first support surface 150b and the first support surface 150d have a similar configuration to the first support surface 150a, and therefore the lower end 149 of the side surface 140b is disposed more inward than the end 119 on the +Y direction side of the reference surface 110 in conjunction with the first support surface 150b and the first support surface 150d. As a result, it is possible to prevent a gap from being generated between the lower end 149 of the side surface 140b and the end 119 of the reference surface 110 on the +Y direction side.

[0126] As described above with reference to Figs. 23(a) to 31, the cover surface 180 has the cover body portion 181 and the protrusion portion 182. The protrusion portion 182 protrudes from the cover body portion 181. The opposing surface 130 has the insertion port 132 formed therein. The protrusion portion 182 can be inserted into the insertion port 132. The opposing surface 130 has a restricting portion 134. The restricting portion 134 restricts the movement of the protrusion portion 182 when the protrusion portion 182 is inserted into the insertion port 132. Therefore, it is possible to prevent the protrusion portion 182 from coming out of the insertion port 132. As a result, the cover surface 180 is firmly fixed to the opposing surface 130. Therefore, the cover surface 180 can be closed as shown in Fig. 29 without using tape or glue.

[0127] In this embodiment, similarly to the fourth embodiment, the packaging tool 1 may further include a film 30. In this case, similarly to the fourth embodiment, the plate 100 is provided with a folding line 21.

[0128] The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 31). However, the present invention is not limited to the above embodiments, and can be implemented in various forms without departing from the scope of the present invention (for example, (1) to (2) shown below). The drawings are mainly schematic illustrations of the respective components for ease of understanding, and the thickness, length, number, etc. of each component shown in the drawings differ from the actual ones due to the convenience of drawing. Furthermore, the materials, shapes, dimensions, etc. of each component shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible without substantially departing from the effects of the present invention.

[0129] (1) Although the film 30 is cylindrical, the present invention is not limited to this. For example, the film 30 may be sheet-shaped. In this case, the film 30 may be attached to the plate 100 by adhering the film 30 to the plate 100.

[0130] (2) The material of the plate and the film is not limited to the above embodiment. In addition to cardboard, thick paper may be used as the plate. The plate is not limited to being made of paper, but may be made of resin such as polyethylene or rubber. If the plate is made of rubber, when the plate is in an unfolded state, it is possible to apply tension to the film by the repulsive force of the plate. The plate may be a plate-shaped member that can be folded and then unfolded again. The film is not limited to being made of resin such as polyethylene or rubber, but may be made of fiber or paper. The paper film is, for example, high-quality paper, so-called printing paper. If the film is paper, it is easy to apply letters and patterns to the film by printing on the film. If the film is paper, it is easy to color the film by printing on the film. The film may be Japanese paper. If the film is Japanese paper, the film has elasticity. The film may be cloth. The film is, for example, opaque. If the film is resin, the end of the film may be fixed to the plate by welding. The film may or may not be stretchable, but it is preferable that the film be stretchable so that tension is applied to the film when the plate is in the unfolded state. [Explanation of symbols]
