[0009] [1. Overview of the Box] Hereinafter, a box 1 which is an example of an embodiment of the present disclosure will be described. In the following description, a state where the box 1 is placed on a horizontal plane (not shown) such as a floor surface will be described, and the directions of X1 and X2 along the horizontal plane are referred to as the left direction and the right direction, respectively. Similarly, the directions of Y1 and Y2 along the horizontal plane (directions perpendicular to the directions of X1 and X2) are referred to as the front direction and the rear direction, respectively. Further, the directions of Z1 and Z2 perpendicular to the horizontal plane are referred to as the upward direction and the downward direction, respectively. However, these directions are defined for explaining the shape and relative positional relationship of elements such as members and parts of the box 1, and do not limit the posture of the box 1 with respect to the horizontal plane.

[0010] Figs. 1A to 1E are perspective views of a box 1 which is an example of an embodiment of the present disclosure. The box 1 is formed by folding a flat box material (see Fig. 4) such as cardboard, corrugated paper, or plastic. The box 1 has a storage portion 10 in which articles (not shown) such as replacement parts of an input device are stored, and a lid portion 20 connected to the storage portion 10. Fig. 1A shows a state in which the lid portion 20 of the box 1 is closed, and Figs. 1B to 1 E show a state in which the lid portion 20 is open. Fig. 2 is a front view of the box 1 with the lid portion 20 closed. Fig. 3 is a cross-sectional view taken along line III-III shown in Fig. 2.

[0011] As shown in Fig. 1A, with the lid portion 20 closed, the shape of the box 1 is rectangular parallelepiped. As shown in Fig. 1B, inside the storage portion 10, a storage space S1 having a shape recessed with respect to the upper end portion (a ceiling wall portion 13 described later) of the storage portion 10 is defined. Articles are stored inside this storage space S1. As shown in Figs. 1A and 1B, with the lid portion 20 closed in the box 1, the lid portion 20 covers the upper side of the storage portion 10 and the storage space S1.

[0012] As shown in Fig. 1B, the storage portion 10 has an inner peripheral wall portion 11 that surrounds the storage space S1 and is open in the vertical direction, and an outer peripheral wall portion 12 that surrounds the inner peripheral wall portion 11. Further, the storage portion 10 has a ceiling plate portion 13 that is connected to the upper end portion of the inner peripheral wall portion 11 and the upper end portion of the outer peripheral wall portion 12 via a fold. Also, as shown in Figs. 2 and 3, the storage portion 10 has a bottom plate portion 14 that constitutes the bottom of the storage portion 10, and a middle plate portion 15 that is disposed along the bottom plate portion 14 above the bottom plate portion 14 and constitutes the bottom of the storage space S1. As shown in Fig. 3, the bottom plate portion 14 covers the lower side of the storage space S1. The outer peripheral wall portion 12 is disposed along the edge of the bottom plate portion 14 and surrounds the bottom plate portion 14. The storage space S1 is located at the central portion of the storage portion 10 in plan view, and a gap (for example, the gaps shown by the arrows D1 and D2 in Fig. 3) is formed between the inner peripheral wall portion 11 that surrounds the storage space S1 and the outer peripheral wall portion 12 that surrounds the bottom plate portion 14. By forming a gap between the inner peripheral wall portion 11 and the outer peripheral wall portion 12, it is possible to suppress the impact generated on the outer peripheral wall portion 12 due to the fall of the box 1 or the like from being transmitted to the storage space S1, and to protect the articles stored in the storage space S1 from the impact.

[0013] In plan view, the storage portion 10 is rectangular, and the outer peripheral wall portion 12 has a rear outer wall portion 12B (first outer wall portion), a front outer wall portion 12F (second outer wall portion), a left outer wall portion 12L (third outer wall portion), and a right outer wall portion 12R (fourth outer wall portion) as shown in Figs. 1B and 1C. The rear outer wall portion 12B is formed on the rear side of the outer peripheral wall portion 12 (one side in the first direction perpendicular to the vertical direction), the front outer wall portion 12F is formed on the front side of the outer peripheral wall portion 12 (the other side in the first direction), the left outer wall portion 12L is formed on the left side of the outer peripheral wall portion 12 (one side in the second direction perpendicular to the vertical direction and the first direction), and the right outer wall portion 12R is formed on the right side of the outer peripheral wall portion 12 (the other side in the second direction).

[0014] In addition, in plan view, the storage space S1 is rectangular, and as shown in FIGS. 1B and 1C, the inner peripheral wall portion 11 has a rear inner wall portion 11B (first inner wall portion), a front inner wall portion 11F (second inner wall portion), a left inner wall portion 11L (third inner wall portion), and a right inner wall portion 11R (fourth inner wall portion). The rear inner wall portion 11B is formed on the rear side of the inner peripheral wall portion 11, the front inner wall portion 11F is formed on the front side of the inner peripheral wall portion 11, the left inner wall portion 11L is formed on the left side of the inner peripheral wall portion 11, and the right inner wall portion 11R is formed on the right side of the inner peripheral wall portion 11.

[0015] The wall top plate portion 13 has a rear wall top plate portion 13B (first wall top plate portion) connected to the rear inner wall portion 11B and the rear outer wall portion 12B via folds, a front wall top plate portion 13F (second wall top plate portion) connected to the front inner wall portion 11F and the front outer wall portion 12F via folds, a left wall top plate portion 13L (third wall top plate portion) connected to the left inner wall portion 11L and the left outer wall portion 12L via folds, and a right wall top plate portion 13R (fourth wall top plate portion) connected to the right inner wall portion 11R and the right outer wall portion 12R via folds. The rear wall top plate portion 13B, the front wall top plate portion 13F, the left wall top plate portion 13L, and the right wall top plate portion 13R are all trapezoidal. By adjacent to each other, the wall top plate portion 13 is formed in a rectangular frame shape in plan view. Further, between the front outer wall portion 12F and the front wall top plate portion 13F, along these folds, the front end portion of the lid portion 20 (insertion portion 22 described later) is inserted An insertion port G is formed.

[0016] As shown in FIGS. 1C and 1D, the rear outer wall portion 12B formed on the rear side of the outer peripheral wall portion 12 can be opened and closed outward about the fold line with the wall top plate portion 13 (more specifically, the rear wall top plate portion 13B) when the lid portion 20 is open. As shown in FIG. 3, inside the storage portion 10, a space S2 different from the storage space S1 is defined by the rear inner wall portion 11B, the rear outer wall portion 12B, the rear wall top plate portion 13B, and the bottom plate portion 14. When the rear outer wall portion 12B opens outward with respect to the storage portion 10, accessories such as spare parts of the article, warranty certificates, and instruction manuals can be taken in and out inside the space S2. In addition, regulation portions 16L and 16R that are bent with respect to the rear outer wall portion 12B are formed at the left end portion and the right end portion of the rear outer wall portion 12B. When the edge portions E1 and E2 (see FIG. 1E) of the regulation portions 16L and 16R contact the lower surface of the wall top plate portion 13, the movement of the rear outer wall portion 12B inside the storage portion 10 can be regulated.

[0017] As shown in FIG. 3, the middle plate portion 15 is disposed above the bottom plate portion 14, and a flat space S3 is defined by the gap between the middle plate portion 15 and the bottom plate portion 14. The space S3 is connected to the space S2, and when the rear outer wall portion 12B opens outward with respect to the storage portion 10, accessories such as warranty certificates and instruction manuals can also be taken in and out inside the space S3. In addition, by forming the space S3 between the storage space S1 and the bottom plate portion 14, the impact generated on the bottom plate portion 14 due to the drop of the box 1 or the like can be suppressed from being transmitted to the storage space S1.

[0018] As shown in FIG. 1C, when the rear outer wall portion 12B is closed, the rear wall top plate portion 13B, the front wall top plate portion 13F, the left wall top plate portion 13L, and the right wall top plate portion 13R that constitute the wall top plate portion 13 are located on the same plane. As shown in FIG. 1E, when the rear outer wall portion 12B opens, the rear wall top plate portion 13B (connection end portion) connected to the rear outer wall portion 12B rear outer wall portion 12BIt can move above the front wall top plate portion 13F, the left wall top plate portion 13L, and the right wall top plate portion 13R, centering on the fold with it. In this way, when the rear outer wall portion 12B opens outward, the rear wall top plate portion 13B connected to the rear outer wall portion 12B moves upward, making it easier to open the rear outer wall portion 12B compared to the case where only the rear outer wall portion 12B moves.

[0019] As shown in FIGS. 1A and 1B, the lid portion 20 includes a top plate portion 21 that covers the storage space S1 and the wall top plate portion 13 of the storage portion 10 in a state where the lid portion 20 is closed, an insertion portion 22 connected to the front end portion of the top plate portion 21 via a fold, and a side plate portion 23 connected to the rear end portion of the top plate portion 21 via a fold. In a state where the lid portion 20 is closed, the top plate portion 21 of the lid portion 20 covers the entire storage portion 10 in a plan view. Further, the insertion portion 22 of the lid portion 20 is inserted into the insertion port G when the lid portion 20 is closed, suppressing the lid portion 20 from opening without an external force being applied.

[0020] As shown in FIG. 1C, the side plate portion 23 of the lid portion 20 is connected to the bottom plate portion 14 via a fold. As shown in FIG. 3, in a state where the lid portion 20 is closed, the side plate portion 23 is in contact with and covers the outer surface of the rear outer wall portion 12B. By covering the outer surface of the rear outer wall portion 12B with the side plate portion 23 of the lid portion 20 in a state where the lid portion 20 is closed, the rear outer wall portion 12B can be restricted from opening outward. Thereby, it is possible to suppress the accessories stored in the space S2 or the space S3 from falling out to the outside of the rear outer wall portion 12B.

[0021] Also, as shown in FIG. 1B, an arc-shaped cut K is formed in the side plate portion 23. Both ends of the cut K are connected to the fold with the top plate portion 21, and the cantilever plate portion 24 defined by the cut K and the fold can bend with respect to the top plate portion 21 at an angle different from the angle formed by the top plate portion 21 and the side plate portion 23. The cantilever plate portion 24 may protrude rearward of the side plate portion 23, for example, in a state where the lid portion 20 is closed. By pulling the cantilever plate portion 24 of the box 1 rearward in a state where the box 1 is stored in an outer box (not shown), it becomes possible to pull the box 1 rearward out of the outer box.

[0022] [Relationship with the development view] FIG. 4 is a plan view of the flat box material constituting the box 1. The box 1 is formed by folding the box material shown in FIG. 4 along the fold lines. In FIG. 4 and FIGS. 5A to 5D described later, the dotted line indicates the mountain fold line, and the dashed-dotted line indicates the valley fold line.

[0023] As shown in FIG. 4, the rear wall top plate portion 13B is connected to the rear inner wall portion 11B and the rear outer wall portion 12B via a fold line. Similarly, the front wall top plate portion 13F is connected to the front inner wall portion 11F and the front outer wall portion 12F via a fold line, the left wall top plate portion 13L is connected to the left inner wall portion 11L and the left outer wall portion 12L via a fold line, and the right wall top plate portion 13R is connected to the right inner wall portion 11R and the right outer wall portion 12R via a fold line.

[0024] Also, in the development view shown in FIG. 4, the rear inner wall portion 11B, the front inner wall portion 11F, the left inner wall portion 11L, and the right inner wall portion 11R that constitute the inner peripheral wall portion 11 are formed at positions separated from each other. Among the wall portions constituting the inner peripheral wall portion 11, the rear inner wall portion 11B and the front inner wall portion 11F are connected to the front end portion and the rear end portion of the middle plate portion 15 via fold lines, respectively, but the left inner wall portion 11L and the right inner wall portion 11R are not connected to the middle plate portion 15. By doing so, it becomes possible to assemble the box 1 from a single plate-like box material.

[0025] As shown in FIG. 4, support pieces 34L and 34R are formed at the left end portion and the right end portion of the middle plate portion 15. The support pieces 34L and 34R support the middle plate portion 15 by being bent downward with respect to the middle plate portion 15 and contacting the bottom plate portion 14, and form a space S3 (see FIG. 3) between the bottom plate portion 14 and the middle plate portion 15. The width D3 of the middle plate portion 15 in the left-right direction (the distance between the support piece 34L and the support piece 34R) is equal to the width D4 of the bottom plate portion 14 in the left-right direction. By doing so, a sufficient width can be ensured in the left-right direction in the space S3 between the bottom plate portion 14 and the middle plate portion 15.

[0026] As shown in FIG. 4, on the rear inner wall portion 11B, the first extending portions 31L and 31R are connected via a fold. The first extending portions 31L and 31R are respectively connected to the left end portion and the right end portion of the rear inner wall portion 11B. On the front inner wall portion 11F, the second extending portions 32L and 32R are connected via a fold. The second extending portions 32L and 32R are respectively connected to the left end portion and the right end portion of the front inner wall portion 11F. The first extending portions 31L and 31R have a concave portion C1 on the outer edge, and the second extending portions 32L and 32R have a concave portion C2 on the outer edge. In the example shown in FIG. 4, the first extending portions 31L and 31R and the second extending portions 32L and 32R are formed in the same shape. The functions of the first extending portions 31L and 31R and the second extending portions 32L and 32R will be described later.

[0027] As shown in FIG. 4, on the left inner wall portion 11L and the right inner wall portion 11R, the insertion portions 33L and 33R are connected via a fold. The insertion portion 33L is formed on the side of the left inner wall portion 11L opposite to the side where the left wall top plate portion 13L is formed. The insertion portion 33R is formed on the side of the right inner wall portion 11R opposite to the side where the right wall top plate portion 13R is formed. The functions of the insertion portions 33L and 33R will be described later.

[0028] In the developed view shown in FIG. 4, the rear outer wall portion 12B, the front outer wall portion 12F, the left outer wall portion 12L, and the right outer wall portion 12R that constitute the outer peripheral wall portion 12 are formed at positions separated from each other. Among the wall portions that constitute the outer peripheral wall portion 12, the front outer wall portion 12F, the left outer wall portion 12L, and the right outer wall portion 12R are connected to the bottom plate portion 14 via a fold. In the outer peripheral wall portion 12, the rear outer wall portion 12B is not connected to the left outer wall portion 12L, the right outer wall portion 12R, and the bottom plate portion 14. For this reason, in a state where the box 1 is assembled and the lid portion 20 is opened, the rear outer wall portion 12B can be opened and closed outside the storage portion 10.

[0029] Also, in the developed view shown in FIG. 4, the rear wall top plate portion 13B, the front wall top plate portion 13F, the left wall top plate portion 13L, and the right wall top plate portion 13R that constitute the wall top plate portion 13 are formed at positions separated from each other. In the wall top plate portion 13, since the rear wall top plate portion 13B is not connected to the left wall top plate portion 13L and the right wall top plate portion 13R, as shown in FIG. 1E, when the rear outer wall portion 12B opens, the rear wall top plate portion 13B connected to the rear outer wall portion 12B can move upward with respect to the front wall top plate portion 13F, the left wall top plate portion 13L, and the right wall top plate portion 13R.

[0030] [3. Assembly of the box] FIGS. 5A to 5D are diagrams for explaining the method of assembling the box 1. In FIGS. 5A to 5D, the cut line K and the cantilever plate portion 24 shown in FIG. 4 are not shown.

[0031] First, as shown in FIG. 5A, in the flat box material, the front outer wall portion 12F is bent with respect to the bottom plate portion 14, and the front wall top plate portion 13F is bent with respect to the front outer wall portion 12F. Then, the rear outer wall portion 12B is bent with respect to the rear wall top plate portion 13B, the rear inner wall portion 11B is bent with respect to the rear wall top plate portion 13B and the middle plate portion 15, and the front inner wall portion 11F is bent with respect to the front wall top plate portion 13F and the middle plate portion 15. In this step, the front outer wall portion 12F, the front wall top plate portion 13F, the front inner wall portion 11F, the middle plate portion 15, the rear inner wall portion 11B, the rear wall top plate portion 13B, and the rear outer wall portion 12B are arranged in this order from the front in the rear. In FIG. 5A, the left and right wall top plate portions 13L, 13R, the inner wall portions 11L, 11R, and the insertion portions 33L, 33R are also bent, but these may be bent in a later step.

[0032] Next, as shown in FIGS. 5A and 5B, the first extension portions 31L and 31R are bent forward with respect to the rear inner wall portion 11B, and the second extension portions 32L and 32R are bent backward with respect to the front inner wall portion 11F. At this time, the recess C2 formed at the edge of the second extension portion 32L is hooked on the recess C1 formed at the edge of the first extension portion 31L on the left side, thereby fixing the first extension portion 31L and the second extension portion 32L. Similarly, the recess C2 formed at the edge of the second extension portion 32R is hooked on the recess C1 formed at the edge of the first extension portion 31R on the right side, thereby fixing the first extension portion 31R and the second extension portion 32R. Further, the support pieces 34L and 34R are bent downward with respect to the middle plate portion 15.

[0033] FIG. 5C shows a state of the box 1 being assembled shown in FIG. 5B as viewed from above. As shown in FIG. 5C, in a state where the first extension portion 31L and the second extension portion 32L on the left side are combined with each other, these extension portions extend in an oblique direction with respect to the front-rear direction. Also, in a state where the first extension portion 31R and the second extension portion 32R on the right side are combined with each other, these extension portions extend in an oblique direction with respect to the front-rear direction. Thereby, in a plan view of the box 1, a hexagon is formed with the first extension portions 31L and 31R, the second extension portions 32L and 32R, the rear inner wall portion 11B, and the front inner wall portion 11F as respective sides. Here, a gap (second gap) is formed between the first extension portion 31L and the second extension portion 32L that are combined with each other and the middle plate portion 15. Also, a gap (second gap) is formed between the first extension portion 31R and the second extension portion 32R that are combined with each other and the middle plate portion 15.

[0034] Next, as shown in FIGS. 5B and 5D, by bending the left outer wall portion 12L, the left wall top plate portion 13L, the left inner wall portion 11L, and the insertion portion 33L, the left portion of the storage portion 10 is formed. In this process, the left first extension portion 31L and the second extension portion 32L are disposed below the left wall top plate portion 13L, and the left inner wall portion 11L is disposed inside the first extension portion 31L and the second extension portion 32L. Further, in this process, the insertion portion 33L is inserted into a gap (second gap) formed between the first extension portion 31L and the second extension portion 32L and the middle plate portion 15. As described above, since the first extension portion 31L and the second extension portion 32L extend in an oblique direction with respect to the front-rear direction, the upper surface of the insertion portion 33L comes into contact with the insertion portion 33L in a wider region T1 than when these extension portions extend only in the front-rear direction. Therefore, it is possible to effectively suppress the insertion portion 33L from coming off from the gap formed between the first extension portion 31L and the second extension portion 32L and the middle plate portion 15. Thereby, it is possible to suppress the left inner wall portion 11L from moving inward about the fold line with the left wall top plate portion 13L.

[0035] Similarly, by bending the right outer wall portion 12R, the right wall top plate portion 13R, the right inner wall portion 11R, and the insertion portion 33R, the right portion of the storage portion 10 is formed. In this process, the right first extension portion 31R and the second extension portion 32R are disposed below the right wall top plate portion 13R, and the right inner wall portion 11R is disposed inside the first extension portion 31R and the second extension portion 32R. In this process, the insertion portion 33R is inserted into a gap formed between the first extension portion 31R and the second extension portion 32R and the middle plate portion 15. The first extension portion 31R and the second extension portion 32R come into contact with the upper surface of the insertion portion 33R in a wider region T2 than when these extension portions extend only in the front-rear direction. Thereby, it is possible to suppress the right inner wall portion 11R from moving inward about the fold line with the right wall top plate portion 13R.

[0036] Finally, the restricting portions 16L and 16R are bent with respect to the rear outer wall portion 12B, and the restricting portions 16L and 16R are stored inside the storage portion 10 (inside the space S2 shown in FIG. 3). Then, the side plate portion 23, the upper plate portion 21, and the insertion portion 22 are bent with respect to the bottom plate portion 14, and the insertion portion 22 is inserted inside the insertion opening G. Through the above steps, the box 1 can be assembled from a box material such as a sheet of cardboard or corrugated paper.

[0037] [4. Summary] As described above, the box 1 described in this embodiment includes a storage portion 10 in which a storage space S1 for storing an article is defined, and a lid portion 20 that covers the upper side of the storage portion 10. The storage portion 10 includes an inner peripheral wall portion 11 that surrounds the storage space S1, an outer peripheral wall portion 12 that surrounds the inner peripheral wall portion 11 and forms a gap between the inner peripheral wall portion 11, and a wall top plate portion 13 that is connected to the upper end portion of the outer peripheral wall portion 12 and the upper end portion of the inner peripheral wall portion 11 via a fold line. By forming a gap between the outer peripheral wall portion 12 and the inner peripheral wall portion 11, it is possible to suppress the impact generated on the outer peripheral wall portion 12 due to the dropping of the box 1 or the like from being transmitted to the storage space S1 defined by the inner peripheral wall portion 11. Therefore, the article stored in the storage space S1 can be protected from impact.

[0038] Also, the outer peripheral wall portion 12 of the box 1 has a rear outer wall portion 12B that can be opened and closed outward about the fold line with the wall top plate portion 13 Thereby, a space (for example, the space S2) for storing the accessories of the article can be secured between the inner peripheral wall portion 11 (the rear inner wall portion 11B) and the rear outer wall portion 12B. Further, the lid portion 20 has a side plate portion 23 that covers the outer surface of the rear outer wall portion 12B when the lid portion 20 is closed. Thereby, when the lid portion 20 is closed, the opening of the rear outer wall portion 12B to the outside can be restricted, and the accessories stored inside the rear outer wall portion 12B can be prevented from falling out to the outside.
