Modes for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention (hereinafter referred to as the present embodiment) will be described in detail with reference to the drawings.

[0015] [Overview of the Shipping Box Unit 100] First, with reference to FIGS. 1 to 4, an overview of the shipping box unit 100 of the present embodiment will be described. FIG. 1 is a perspective view showing the shipping box unit in an assembled state. FIG. 2 is a plan view showing the shipping box unit in a deployed state. FIG. 3 is a front view showing the shipping box unit in a folded state. FIG. 4 is a top view showing the shipping box unit in an assembled state as viewed from above. When the shipping box unit 100 is viewed directly from above, the mounting table 20 and the fixing parts 11A, 11B, and 11C described later are visible, but their illustrations are omitted in FIG. 4.

[0016] Also, in each figure, the thickness and length of each part are not strictly represented and are not limited to the illustrated examples. Further, in FIGS. 3 and 4, each fold line is represented by a portion surrounded by a broken-line circle, but each fold line may be a linear portion having substantially no width.

[0017] The shipping box unit 100 is for accommodating and transporting luggage. The shipping box unit 100 is configured to be in an assembled state, a deployed state, and a folded state. The assembled state is the state shown in FIG. 1 where each side plate 10 is erected and luggage can be accommodated inside. The deployed state is the state shown in FIG. 2 where each side plate 10 is deployed. The folded state is the state shown in FIG. 3 where each side plate 10 is folded and stacked above the mounting table 20.

[0018] The shipping box unit 100 includes a mounting table 20 and four side plates 10 standing on the mounting table 20. In the shipping box unit 100, three side plates 10A to 10C are fixed to the upper surface (mounting surface) of the mounting table 20, and one side plate 10D is configured to be detachable from the mounting table 20. That is, the mounting table 20 and the side plates 10A to 10C are integrally formed, and the side plate 10D is separate. In this specification, when it is not necessary to distinguish and describe the side plates 10A to 10D, they will simply be referred to as "side plate 10".

[0019] In this embodiment, as the side plate 10, a plate material formed by laminating paperboard (referred to as a core or the like) formed in a corrugated shape on one or both sides with paperboard (referred to as a liner or the like), that is, cardboard, is adopted. For the mounting table 20 as well, a configuration formed by bending or laminating cardboard is adopted. By adopting such a configuration made of inexpensive cardboard, it is possible to reduce the cost of the transportation box unit 100 itself. Further, at the destination, the cardboard constituting the transportation box unit 100 can be disposed of or recycled, so there is no need to return it to the sender or manage it at the destination. Therefore, the return cost and the management cost can be reduced, and as a result, the transportation cost can be reduced.

[0020] Note that, in this embodiment, an example in which each member constituting the transportation box unit 100 is made of cardboard is described, but the present invention is not limited to this, and other plate materials that are inexpensive, lightweight, and easy to dispose of or recycle may be used.

[0021] In this embodiment, as shown in FIG. 2, the side plate 10D side in the transportation box unit 100 is defined as the front side, the side plate 10C side as the rear side, the side plate 10A side as the left side, and the side plate 10B side as the right side. That is, FIG. 1 shows a perspective view of the transportation box unit 100 as seen from the front right obliquely.

[0022] In the assembled transportation box unit 100, within the accommodation area C (see FIG. 4) surrounded by the four side plates 10, luggage such as furniture is accommodated on the mounting table 20. The luggage such as furniture accommodated in the transportation box unit 100 is not visible to a third party from the outside during transportation such as a move.

[0023] The uses of the transportation box unit 100 include mixed-load transportation and moving, etc., but are not limited to this, and it can be used for all transportation of carrying luggage.

[0024] [Mounting table 20] The mounting table 20 is a pallet with a rectangular planar shape. In the present embodiment, an example where the planar shape of the mounting table 20 is a square will be described, but it is not limited thereto, and any rectangle having at least four sides may be used.

[0025] As shown in FIG. 3, the mounting table 20 includes a bottom plate 21, a plurality of girders 22 having a predetermined height, and a top plate 23. The upper surface of the top plate 23 is a mounting surface on which each side plate 10 and the luggage are mounted. An opening OP for inserting a lift claw is formed between the plurality of girders 22. In the present embodiment, an example is shown in which the opening OP is formed so that the lift claws are inserted from the front side and the rear side, but it is not limited thereto, and openings may be formed on the right side and the left side, or openings may be formed on any of the front side, the rear side, the right side, and the left side. In order to avoid complicating the drawing, the illustration of the bottom plate 21 and the top plate 23 is omitted except in FIG. 3. That is, the thicknesses of the bottom plate 21 and the top plate 23 are not shown.

[0026] [Details of each side plate 10] Next, with reference to FIGS. 1 to 4, the details of each side plate 10 will be described. In each figure, each fold line is shown by a dotted line. Further, each fold line provided on each side plate 10 may be formed so as to allow folding inward.

[0027] The side plates 10A to 10C have widths corresponding to the widths of the respective sides of the mounting surface of the mounting table 20, and are respectively fixed to the ends of the mounting surface. Specifically, the side plate 10A is fixed to the left end of the mounting table 20, the side plate 10B is fixed to the right end of the mounting table 20, and the side plate 10C is fixed to the rear end of the mounting table. Further, no side plate is fixed to the front end of the mounting table 20, and a space where the side plate 10D can be mounted is provided.

[0028] [Side plate 10A] The side plate 10A is movably fixed to the mounting table 20 between the deployed position and the upright position where it stands on the mounting table 20. The side plate 10A includes a fixing portion 11A, an upright portion 12A, and overlapping portions 13A and 14A.

[0029] The fixing part 11A and the standing part 12A are connected with the folding line F1a as a boundary. The folding line F1a is provided along the left edge of the mounting table 20.

[0030] The standing part 12A and the overlapping part 13A are connected with the folding line F2a as a boundary. Also, the standing part 12A and the overlapping part 14A are connected with the folding line F3a as a boundary. The folding line F2a and the folding line F3a are provided so as to extend in the vertical direction in a state where the side plate 10A stands on the mounting table 20.

[0031] The fixing part 11A is a part fixed to the left end portion of the mounting surface of the mounting table 20. The fixing part 11A is preferably fixed by adhesion or the like. However, the fixing method is not limited to this. As shown in FIG. 2, the fixing part 11A has a trapezoidal planar shape. This is a shape adopted to avoid overlapping with the fixing part 11C of the side plate 10C described later.

[0032] The standing part 12A is a part that stands on the mounting table 20 in the assembled state. The width of the standing part 12A in the front-rear direction is preferably substantially the same as the width of the mounting table 20 in the front-rear direction. Specifically, for example, the width of the standing part 12A in the front-rear direction (the width of the mounting table 20 in the front-rear direction) is preferably about 1100 [mm]. Also, the height of the standing part 12A (L1 + L2 in FIG. 2) is preferably about 1700 [mm]. In this way, in the standing part 12A, it is preferable that the width in the height direction is wider than at least the width in the front-rear direction. Since the height of the standing part 12A is high, it becomes possible to load a lot of luggage in the storage area C or store long objects such as a drying rack. The height of the mounting table 20 is about 90 [mm], and the overall height of the transport box unit 100 in the assembled state is preferably about 1790 [mm].

[0033] The overlapping portion 13A is, in the assembled state, a portion that overlaps with the side plate 10C as shown in FIG. 4. The overlapping portion 13A is located behind the mounting table 20 in the unfolded state. The overlapping portion 14A is, in the assembled state, a portion that overlaps with the side plate 10D as shown in FIG. 4. The overlapping portion 14A is located in front of the mounting table 20 in the unfolded state. Note that in the left-right direction, the width of the overlapping portion 13A may be equal to or less than half of the width of the side plate 10C. Similarly, the width of the overlapping portion 14A may be equal to or less than half of the width of the side plate 10D.

[0034] Furthermore, the side plate 10A is provided with a fold line F4a and a fold line F5a. The fold line F4a and the fold line F5a are provided to fold the transport box unit 100 into a folded state. The fold line F4a and the fold line F5a are provided so as to extend in the horizontal direction when the side plate 10A stands on the mounting table 20. The fold line F4a is provided between the fold line F1a and the fold line F5a.

[0035] Also, as shown in FIG. 2, in the unfolded state, when the length from the fold line F1a to the fold line F5a (the lower part of the side plate 10A) is L1 and the length from the fold line F5a to the left end of the side plate 10A (the upper part of the side plate 10A) is L2, the relationship L2≦L1 is preferably satisfied. Thereby, the side plate 10A can be folded inward through the fold line F5a without interfering with other parts. Also, L1 is preferably shorter than the width of the mounting table 20. Thereby, in the folded state, the side plate 10A can be folded without protruding to the right from the mounting table 20.

[0036] [Side plate 10B] The side plate 10B is movably fixed to the mounting table 20 between the deployed position and the upright position where it stands on the mounting table 20. The side plate 10B is fixed to the mounting surface of the mounting table 20 at a position facing the side plate 10A, and its shape is symmetrical with the side plate 10A about the left and right. Therefore, detailed descriptions of each part and each fold line in the side plate 10B are omitted. Note that in the side plate 10B and the side plate 10A, among the reference numerals representing each part and each fold line shown in FIG. 2, the difference in the Roman letters associated with the reference numerals is whether they are "A, a" or "B, b", and those with the same number have the same function.

[0037] However, only the position of the fold line F4b may be asymmetrical with the fold line F4a. This is because in the folded state, the side plates 10A and 10B are folded so as to overlap each other, and the heights in the folded state are different from each other. As shown in FIG. 3, since the side plate 10B is arranged above the side plate 10A in the folded state, the fold line F4b is preferably provided at a higher position than the fold line F4a. That is, as shown in FIG. 2, the relationship between the length L4 between the fold line F1b and the fold line F4b and the length L3 between the fold line F1a and the fold line F4a is preferably L4 > L3. Note that when the side plate 10A is arranged above the side plate 10B in the folded state, L4 < L3 may be appropriate. Also, L3 = L4 may be possible. In this case, since the configurations of the side plates 10A and 10B are the same, mass production of the side plates 10A and 10B becomes easy.

[0038] [Side plate 10C] The side plate 10C is movably fixed to the mounting table 20 between the deployed position and the upright position where it stands on the mounting table 20 by being supported by the side plates 10A and 10B. The side plate 10C includes a fixing portion 11C and an upright portion 12C. The fixing portion 11C and the upright portion 12C are connected with the fold line F1c as a boundary. The fold line F1c is provided along the rear edge of the mounting table 20.

[0039] The fixing part 11C is the part fixed to the rear end of the mounting surface of the mounting table 20. The fixing part 11C may be fixed to the mounting surface of the mounting table 20 by adhesion or the like. However, the fixing method is not limited to this. The standing part 12C is the part that stands on the mounting table 20 in the assembled state.

[0040] Furthermore, a fold line F2c is provided on the side plate 10C. The fold line F2c is provided for folding the transportation box unit 100 into a folded state. The fold line F2c is provided so as to extend in the horizontal direction when the side plate 10C stands on the mounting table 20. In the standing state, the fold line F2c of the side plate 10C may be provided at the same height as the fold line F5a of the side plate 10A and the fold line F5b of the side plate 10B.

[0041] [Side plate 10D] The side plate 10D is rectangular and, unlike the above-described side plates 10A to 10C, no fixing part is provided. That is, the side plate 10D is not fixed to the mounting table 20.

[0042] A fold line F1d is formed on the side plate 10D. The fold line F1d may be provided, for example, at the center in the height direction of the side plate 10D. That is, as shown in FIG. 3, the side plate 10D may be foldable so that its width is halved with the fold line F1d as a boundary. As shown in FIG. 1, the fold line F1d is provided below the fold line F5b (fold line F5a of the side plate 10A) of the side plate 10B in the assembled state.

[0043] [Assembly process] Referring to FIGS. 1, 2, and 5A to 5C, the assembly process of the transportation box unit 100 will be described.

[0044] First, prepare the transportation box unit 100 in the unfolded state shown in FIG. 2.

[0045] Then, the side plate 10A is bent through the fold line F1a, and the standing part 12A is made to stand on the mounting table 20. As a result, the state shown in FIG. 5A is obtained. In the state shown in FIG. 5A, since the side plate 10A is unstable, it is necessary for the user to support the side plate 10A.

[0046] Next, the side plate 10C is bent through the fold line F1c, and the standing part 12C is made to stand on the mounting table 20. Further, the side plate 10A is bent through the fold line F2a, and the overlapping part 13A is arranged along the inner surface of the side plate 10C. At this time, the through hole h formed in the overlapping part 13A is aligned with the through hole h formed in the side plate 10C. Then, a clamping tool (not shown) is fitted into these through holes h to fix the side plate 10A and the side plate 10C. As a result, the side plate 10A and the side plate 10C support each other and become self-standing on the mounting table 20. As a result, the state shown in FIG. 5B is obtained. Although the detailed description of the clamping tool is omitted, it may be a member that can sandwich two overlapping side plates and fix those side plates to each other. Also, the clamping tool may be configured to be detachable from the side plate by the user's manual operation.

[0047] Furthermore, the side plate 10B is bent through the fold line F1b, and the standing part 12B is made to stand on the mounting table 20. Further, the side plate 10B is bent through the fold line F2b, and the overlapping part 13B is arranged along the inner surface of the side plate 10C. At this time, the through hole h formed in the overlapping part 13B is aligned with the through hole h formed in the side plate 10C. Then, a clamping tool (not shown) is fitted into these through holes h to fix the side plate 10B and the side plate 10C. As a result, the side plate 10B and the side plate 10C support each other and become self-standing on the mounting table 20. As a result, the state shown in FIG. 5C is obtained. Note that the loading of luggage into the storage area C may be performed in the state shown in FIG. 5C. That is, it is preferable to load the luggage before standing the side plate 10D on the mounting table 20.

[0048] Furthermore, place the side plate 10D on the front end portion of the mounting table 20. At this time, bend the side plate 10A through the fold line F3a. At this time, align the through-hole h formed in the side plate 10D with the through-hole h formed in the overlapping portion 14A. Then, fit a clamping tool (not shown) into these through-holes h to fix the side plate 10D to the side plate 10A.

[0049] Similarly, bend the side plate 10B through the fold line F3b to align the through-hole h formed in the side plate 10D with the through-hole h formed in the overlapping portion 14A. Then, fit a clamping tool (not shown) into these through-holes h to fix the side plate 10D to the side plate 10B. Thereby, the assembly is completed, and the assembled state shown in FIG. 1 is achieved.

[0050] Furthermore, as shown in FIG. 6, the opening formed above the transport box unit 100 may be closed by the cover plate 30. As shown in FIG. 2, the cover plate 30 includes a lid portion 31, an overlapping portion 32, and an overlapping portion 33. The lid portion 31 and the overlapping portion 32 are connected via the fold line F1e. The lid portion 31 and the overlapping portion 33 are connected via the fold line F2e.

[0051] As shown in FIG. 6, the cover plate 30 is provided such that the lid portion 31 is placed on the upper end of each side plate 10. In that state, bend the cover plate 30 through the fold line F1e and arrange the overlapping portion 32 along the side plate 10C. Also, bend the cover plate 30 through the fold line F2e and arrange the overlapping portion 33 along the side plate 10D.

[0052] Furthermore, although not shown, it is advisable to wrap a wrap or the like around the periphery of the assembled transport box unit 100. At this time, the wrap or the like may be wrapped so as to maintain a state where the overlapping portion 32 is in contact with the side plate 10C and the overlapping portion 33 is in contact with the side plate 10D. Thereby, the standing state of each side plate 10 becomes more stable, and even if the luggage accommodated in the accommodation area C leans against the side plate 10, it is possible to suppress the side plate 10 from falling down.

[0053] [Folding Process] Next, with reference mainly to FIGS. 2 and 3, the folding process of the shipping box unit 100 will be described.

[0054] First, prepare the shipping box unit 100 in the unfolded state shown in FIG. 2.

[0055] Next, bend the side plate 10C through the fold line F2c. Further, bend the side plate 10C through the fold line F1c. As a result, the side plate 10C is placed on the mounting table 20 in a folded state.

[0056] Next, bend the side plate 10D through the fold line F1d and place it on the side plate 10C. At this time, it is advisable to place the side plate 10D in the folded state on the side plate 10C such that the short side direction of the folded side plate 10D is in the left - right direction.

[0057] Next, bend the side plate 10A through the fold line F5a. Further, bend the side plate 10A through the fold lines 1a and F4a. As a result, the side plate 10A will be placed on the side plate 10D in a folded state.

[0058] Next, bend the side plate 10B through the fold line F5b. Further, bend the side plate 10B through the fold lines F1b and F4b. As a result, the side plate 10B will be placed on the side plate 10A in a folded state.

[0059] Through the above steps, the folded state shown in FIG. 3 is achieved. Also, the cover plate 30 shown in FIGS. 2 and 6 may be placed on the side plate 10B in the state shown in FIG. 3. Note that the overlapping order of each side plate is not limited to that described here. Also, the side plate 10D, which is a separate member, may be managed separately instead of being overlapped with the other side plates 10.

[0060] [Summary] In the transport box unit 100 according to the present embodiment, since the mounting table 20 and the three side plates 10 are integrated, the number of parts can be reduced. Therefore, handling during movement and storage of the transport box unit 100 becomes easy. Further, since the three side plates are integrated with the mounting table 20, it is not necessary to consider which side plate is arranged at which position during assembly, and it can be easily assembled. Also, loss of the side plates during movement and storage can be suppressed. Further, by providing fold lines on each side plate 10 so that it can be folded, the whole can be made compact. Specifically, the left-right and front-back widths in the folded state can be made substantially equal to the left-right and front-back widths of the mounting table 20. That is, the outer shape in plan view of the transport box unit 100 in the folded state becomes a shape close to a square. By making it into such a compact folded state, it becomes easy to carry, and other spaces during storage can be widened. Also, the transport box units 100 in the folded state may be stacked and stored, or loaded on the loading platform of a truck. Note that, although the width in the front-back direction becomes wider than that of the mounting table 20 by at least the widths of the overlapping portions 13A, 14A, 13B, and 14B, the widths of the overlapping portions 13A, 14A, 13B, and 14B are about several centimeters and do not cause problems during movement and storage. Note that when the widths of the overlapping portions 13A, 14A, 13B, and 14B are made wide, they may be in the folded state as shown in FIG. 3 in the folded state.

[0061] [Others] As shown in each figure, two through holes h into which clamping tools (not shown) are fitted are formed in the overlapping portion 13A. However, the number of through holes h is not limited to that shown. The through holes h formed in the overlapping portion 13A are preferably formed so as to avoid at least straddling the fold line. Specifically, the through holes h formed in the overlapping portion 13A are preferably formed on the left side and the right side of the fold line F5a, respectively. The same applies to the overlapping portion 14A, the overlapping portion 13B, and the overlapping portion 14B.

[0062] Although illustration is omitted, auxiliary holes may be separately formed adjacent to each through hole h. A person assembling the transport box unit 100 may insert a hand or finger inside through the auxiliary holes so as to be able to access the clamping tool from the inside. This facilitates the handling of the clamping tool.

[0063] As described above, the embodiments according to the present invention have been described. However, the specific configurations shown in these embodiments are shown as examples, and it is not intended to limit the technical scope of the present invention thereto. Those skilled in the art may appropriately modify these disclosed embodiments, and it should be understood that the technical scope of the invention disclosed in this specification includes such modifications.
