[0025] 1. Overview of the box

[0026] Hereinafter, a box 1 will be described as an example of an embodiment of the present disclosure. In the following description, a state in which the box 1 is placed on a horizontal surface (not shown) such as a floor surface will be described, and the directions of X1 and X2 along the horizontal surface will be referred to as the left direction and the right direction, respectively. Similarly, the directions of Y1 and Y2 along the horizontal surface (directions perpendicular to the directions of X1 and X2) will be referred to as the front and the back, respectively. In addition, the directions of Z1 and Z2 perpendicular to the horizontal surface will be referred to as the top and the bottom, respectively. However, these directions are defined in order to illustrate the shapes and relative positional relationships of components, parts and other elements of the box 1, and do not limit the posture of the box 1 relative to the horizontal surface.

[0027] Figures 1A to 1E 1 is a perspective view of a box 1 as an example of an embodiment of the present disclosure. The box 1 is made by folding a flat box material such as cardboard, corrugated cardboard, plastic, etc. (see Figure 4 The case 1 includes a storage portion 10 for storing replacement parts of the input device and other items (not shown) and a cover portion 20 connected to the storage portion 10. Figure 1A The state in which the cover portion 20 of the box 1 is closed is depicted. Figures 1B to 1D A state in which the cover portion 20 is opened is depicted. Figure 2 It is a front view of the cartridge 1 in a state where the cover portion 20 is closed. Figure 3 It is along Figure 2 A cross-sectional view taken along line III-III depicted in FIG.

[0028] like Figure 1A As shown, in the state where the cover portion 20 is closed, the box 1 has a rectangular parallelepiped shape. Figure 1B As shown, a storage space S1 is defined inside the storage portion 10, and the storage space S1 has a shape that is recessed relative to the upper end (the wall top plate portion 13 to be described later) of the storage portion 10. Items are stored inside the storage space S1. Figure 1A and Figure 1B As depicted, in a state in which the cover portion 20 of the box 1 is closed, the cover portion 20 covers the upper side of the storage portion 10 and the storage space S1 .

[0029] like Figure 1BAs depicted in FIG. 1 , the storage portion 10 includes an inner peripheral wall portion 11 and an outer peripheral wall portion 12, the inner peripheral wall portion 11 surrounds the storage space S1 and is open in the up-down direction, and the outer peripheral wall portion 12 surrounds the inner peripheral wall portion 11. In addition, the storage portion 10 includes a wall top plate portion 13 connected to the upper end of the inner peripheral wall portion 11 and the upper end of the outer peripheral wall portion 12 via a fold. In addition, as shown in FIG. Figure 2 and Figure 3 As depicted, the storage portion 10 has a bottom plate portion 14 configuring a bottom portion of the storage portion 10 and an intermediate plate portion 15 arranged above the bottom plate portion 14 along the bottom plate portion 14 and configuring a bottom portion of the storage space S1. Figure 3 As shown, the bottom plate portion 14 covers the lower side of the storage space S1. The peripheral wall portion 12 is arranged along the edge of the bottom plate portion 14 and surrounds the bottom plate portion 14. The storage space S1 is positioned in the center of the storage portion 10 in a plan view, and a gap (e.g., a space) is formed between the inner peripheral wall portion 11 surrounding the storage space S1 and the peripheral wall portion 12 surrounding the bottom plate portion 14. Figure 3 Since a gap is formed between the inner peripheral wall portion 11 and the outer peripheral wall portion 12, the impact caused in the outer peripheral wall portion 12 due to the falling of the box 1 is suppressed from being transmitted to the storage space S1, and the items stored in the storage space S1 can be protected from the impact.

[0030] The storage portion 10 is rectangular in plan view, and the 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 FIG. Figure 1B and Figure 1C The rear outer wall portion 12B is formed on the rear side (one side in the first direction perpendicular to the up-down direction) of the outer peripheral wall portion 12, the front outer wall portion 12F is formed on the front side (the other side in the first direction) of the outer peripheral wall portion 12, the left outer wall portion 12L is formed on the left side (one side in the second direction perpendicular to the up-down direction and the first direction) of the outer peripheral wall portion 12, and the right outer wall portion 12R is formed on the right side (the other side in the second direction) of the outer peripheral wall portion 12.

[0031] In addition, the storage space S1 is rectangular in a plan view, and 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), as shown in FIG. Figure 1B and Figure 1CThe 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.

[0032] The wall top plate part 13 has a rear wall top plate part 13B (first wall top plate part) connected to each of the rear inner wall part 11B and the rear outer wall part 12B via a fold, a front wall top plate part 13F (second wall top plate part) connected to each of the front inner wall part 11F and the front outer wall part 12F via a fold, a left wall top plate part 13L (third wall top plate part) connected to each of the left inner wall part 11L and the left outer wall part 12L via a fold, and a right wall top plate part 13R (fourth wall top plate part), which is connected to each of the right inner wall part 11R and the right outer wall part 12R via a fold. The rear wall top plate part 13B, the front wall top plate part 13F, the left wall top plate part 13L and the right wall top plate part 13R are all trapezoidal. Because these are adjacent to each other, the wall top plate part 13 is formed as a square frame in a plan view. In addition, an insertion port G into which the front end of the cover portion 20 (an insertion portion 22 described later) is inserted is formed along these folds between the front outer wall portion 12F and the front wall top plate portion 13F.

[0033] like Figure 1C and Figure 1D As shown, in the state where the cover portion 20 is opened, the rear outer wall portion 12B formed on the rear side of the peripheral wall portion 12 can be opened and closed to the outside around the fold of the wall top plate portion 13 (more specifically, the rear wall top plate portion 13B). Figure 3 As depicted in the figure, a space S2 different from the storage space S1 is defined inside the storage portion 10 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. The rear outer wall portion 12B is open outwardly relative to the storage portion 10 so that accessories such as spare parts, warranty cards and user manuals of items can be put into and taken out of the space S2. In addition, limiting portions 16L and 16R that are bent relative to the rear outer wall portion 12B are formed at the left and right ends of the rear outer wall portion 12B, respectively. Edge portions E1 and E2 of the limiting portions 16L and 16R (see Figure 1E ) contacts the lower surface of the wall top plate portion 13, thereby limiting the movement of the rear outer wall portion 12B to the interior of the storage portion 10.

[0034] like Figure 3As depicted in FIG. 1 , the middle plate portion 15 is arranged above the bottom plate portion 14, and a flat plate-shaped space S3 is defined by a gap between the middle plate portion 15 and the bottom plate portion 14. The space S3 is communicated with the space S2, and the rear outer wall portion 12B is open outwardly relative to the storage portion 10, so that accessories such as warranty cards and instruction manuals can be put into and taken out of the space S3. In addition, since the space S3 is formed between the storage space S1 and the bottom plate portion 14, it is possible to suppress the impact generated in the bottom plate portion 14 due to the fall of the box 1, etc. from being transmitted to the storage space S1.

[0035] like Figure 1C As shown, in the state where 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 constituting the wall top plate portion 13 are positioned on the same plane. Figure 1E As shown, when the rear outer wall portion 12B is opened, the rear wall top plate portion 13B (connection end) connected to the rear outer wall portion 12B can move upward relative to the front wall top plate portion 13F, the left wall top plate portion 13L and the right wall top plate portion 13R around the fold with the rear wall top plate portion 13B. Therefore, when the rear outer wall portion 12B is opened outward, the rear wall top plate portion 13B connected to the rear outer wall portion 12B moves upward, so that the rear outer wall portion 12B can be easily opened compared to the case where only the rear outer wall portion 12B is moved.

[0036] like Figure 1A and Figure 1B As shown, in the state where the cover part 20 is closed, the cover part 20 has an upper plate part 21 covering the storage space S1 and the wall top plate part 13 of the storage part 10, an insertion part 22 connected to the front end of the upper plate part 21 via a fold, and a side plate part 23 connected to the rear end of the upper plate part 21 via a fold. In the state where the cover part 20 is closed, the upper plate part 21 of the cover part 20 covers the entire storage part 10 in a plan view. In addition, the insertion part 22 of the cover part 20 is inserted into the insertion port G when the cover part 20 is closed, thereby suppressing the cover part 20 from being opened without applying an external force.

[0037] like Figure 1C As shown, the side plate portion 23 of the cover portion 20 is connected to the bottom plate portion 14 by a fold. Figure 3 As shown, in the state where the cover portion 20 is closed, the side plate portion 23 contacts the outer surface of the rear outer wall portion 12B and covers the outer surface of the rear outer wall portion 12B. In the state where the cover portion 20 is closed, the side plate portion 23 of the cover portion 20 covers the outer surface of the rear outer wall portion 12B, thereby restricting the rear outer wall portion 12B from opening outward. Therefore, it is possible to suppress the accessories stored in the space S2 and the space S3 from falling out of the rear outer wall portion 12B.

[0038] In addition, if Figure 1B As shown, a circular arc slit K is formed in the side plate portion 23. Both ends of the slit K are connected to the upper plate portion 21 at the fold, and the cantilever plate portion 24 defined by the slit K and the fold can be bent relative to the upper plate portion 21 at an angle different from the angle formed by the upper plate portion 21 and the side plate portion 23. The cantilever plate portion 24 can protrude to the rear of the side plate portion 23, for example, in a state where the cover portion 20 is closed. When the cantilever plate portion 24 of the box 1 is pulled backward in a state where the box 1 is stored in an outer box (not shown), the box 1 can be pulled out backward from the outer box.

[0039] 2. Relationship with the expansion diagram

[0040] Figure 4 is a plan view of a flat plate-shaped box material constituting the box 1. The box 1 is formed by Figure 4 The box material depicted in is folded along the creases. Figure 4 and the following Figure 5A to Figure 5D In the figure, the dotted lines represent the creases of the mountain fold, and the dashed lines represent the creases of the valley fold.

[0041] like Figure 4 As shown, 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. 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, 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, and the right wall top plate portion 13R is connected to the right inner wall segment portion 11R and the right outer wall portion 12R via a fold.

[0042] In addition, Figure 4 In the development diagram depicted in FIG, 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 constituting 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 and rear ends of the middle plate portion 15 via folds, respectively, but the left inner wall portion 11L and the right inner wall portion 11R are not connected to the middle plate portion 15. With such a configuration, the box 1 can be assembled from a single plate-shaped box material.

[0043] like Figure 4 As shown, the support members 34L and 34R are respectively formed at the left and right ends of the middle plate portion 15. The support members 34L, 34R are bent downward relative to the middle plate portion 15 and contact the bottom plate portion 14 to support the middle plate portion 15, and a space S3 is formed between the bottom plate portion 14 and the middle plate portion 15 (see Figure 3The width D3 of the middle plate portion 15 in the left-right direction (the distance between the support member 34L and the support member 34R) is equal to the width D4 of the bottom plate portion 14 in the left-right direction. With this configuration, a sufficient space in the left-right direction can be ensured in the space S3 between the bottom plate portion 14 and the middle plate portion 15.

[0044] like Figure 4 As depicted in , the first extension portions 31L and 31R are connected to the rear inner wall portion 11B via a fold. The first extension portions 31L and 31R are connected to the left and right ends of the rear inner wall portion 11B, respectively. The second extension portions 32L and 32R are connected to the front inner wall portion 11F via a fold. The second extension portions 32L and 32R are connected to the left and right ends of the front inner wall portion 11F, respectively. The first extension portions 31L, 31R have a recessed portion C1 at the outer edge, and the second extension portions 32L, 32R have a recessed portion C2 at the outer edge. Figure 4 In the example depicted in FIG. 1 , the first extension portions 31L and 31R and the second extension portions 32L and 32R are formed in the same shape. The functions of the first extension portions 31L and 31R and the second extension portions 32L and 32R will be described later.

[0045] like Figure 4 As depicted in FIG. 1 , the insertion portions 33L and 33R are connected to the left inner wall portion 11L and the right inner wall portion 11R via folds, respectively. The insertion portion 33L is formed on a side of the left inner wall portion 11L opposite to a side where the left wall top plate portion 13L is formed. The insertion portion 33R is formed on a side of the right inner wall portion 11R opposite to a side where the right wall top plate portion 13R is formed. The functions of the insertion portions 33L and 33R will be described later.

[0046] exist Figure 4 In the development shown, 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 constituting the peripheral wall portion 12 are formed at positions separated from each other. In the wall portion constituting the 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 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. Therefore, in the state where the box 1 is assembled and the cover portion 20 is opened, the rear outer wall portion 12B can be opened and closed to the outside of the storage portion 10.

[0047] In addition, Figure 4In the development diagram depicted in FIG, 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 constituting the wall top plate portion 13 are formed at positions separated from each other. 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 in the wall top plate portion 13, when the rear outer wall portion 12B is opened, the rear wall top plate portion 13B connected to the rear outer wall portion 12B can move upward relative to the front wall top plate portion 13F, the left wall top plate portion 13L, and the right wall top plate portion 13R, as shown in FIG. Figure 1E shown.

[0048] 3. Box Assembly

[0049] FIG. 5A to FIG. 5D 1 and 1 are diagrams each illustrating a method of assembling the box 1. Figure 5A to Figure 5D In, omitted Figure 4 An illustration of the slit K and cantilever plate portion 24 depicted in FIG.

[0050] First, if Figure 5A As shown, in the flat-plate-shaped box material, the front outer wall portion 12F is bent relative to the bottom plate portion 14, and the front wall top plate portion 13F is bent relative to the front outer wall portion 12F. Then, the rear outer wall portion 12B is bent relative to the rear wall top plate portion 13B, the rear inner wall portion 11B is bent relative to the rear wall top plate portion 13B and the middle plate portion 15, and the front inner wall portion 11F is bent relative 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 backwards in this order. It should be noted that in Figure 5A In the process, 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.

[0051] Next, if Figure 5A and Figure 5BAs depicted, the first extension portions 31L and 31R are bent forward relative to the rear inner wall portion 11B, and the second extension portions 32L and 32R are bent backward relative to the front inner wall portion 11F. At this time, the concave portion C2 formed at the edge of the second extension portion 32L is hooked to the concave portion C1 formed at the edge of the first extension portion 31L on the left side, so that the first extension portion 31L and the second extension portion 32L are fixed. Similarly, the concave portion C2 formed at the edge of the second extension portion 32R is hooked to the concave portion C1 formed at the edge of the first extension portion 31R on the right side, so that the first extension portion 31R and the second extension portion 32R are fixed. In addition, the support members 34L, 34R are bent downward relative to the middle plate portion 15.

[0052] Figure 5C Depicts the assembly process as viewed from above. Figure 5B The state of box 1 is depicted in FIG. Figure 5C As shown, in a state where the first extension part 31L and the second extension part 32L on the left side are engaged with each other, these extension parts extend in an inclined direction relative to the front-to-back direction. In addition, in a state where the first extension part 31R and the second extension part 32R on the right side are engaged with each other, these extension parts extend in an inclined direction relative to the front-to-back direction. Thus, in a plan view of the box 1, a hexagon is formed with the first extension parts 31L, 31R, the second extension parts 32L, 32R, the rear inner wall part 11B and the front inner wall part 11F as sides. Here, a gap (second gap) is formed between the first extension part 31L and the second extension part 32L that are engaged with each other and the middle plate part 15. In addition, a gap (second gap) is also formed between the first extension part 31R and the second extension part 32R that are engaged with each other and the middle plate part 15.

[0053] Next, if Figure 5B and Figure 5DAs shown, the left portion of the storage portion 10 is formed 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. Through this step, the first extension portion 31L and the second extension portion 32L on the left side are arranged below the left wall top plate portion 13L, and the left inner wall portion 11L is arranged on the inner side relative to the first extension portion 31L and the second extension portion 32L. In addition, in this step, the insertion portion 33L is inserted into the gap (second gap) formed between the first extension portion 31L and the second extension portion 32L on the one hand and the middle plate portion 15 on the other hand. As described above, since the first extension portion 31L and the second extension portion 32L extend in an inclined direction relative to the front-to-back direction, these extension portions contact the upper surface of the insertion portion 33L in a wider area T1 than the case where these extension portions extend only in the front-to-back direction. Therefore, it is possible to effectively suppress the insertion portion 33L from being separated from the gap between the first extension portion 31L and the second extension portion 32L formed on the one hand and the middle plate portion 15 on the other hand. Therefore, it is possible to suppress the left inner wall portion 11L from moving inwardly around the fold with the left wall top plate portion 13L.

[0054] Similarly, the right part of the storage part 10 is formed by bending the right outer wall part 12R, the right wall top plate part 13R, the right inner wall part 11R and the insertion part 33R. Through this step, the first extension part 31R and the second extension part 32R on the right side are arranged below the right wall top plate part 13R, and the right inner wall part 11R is arranged on the inner side relative to the first extension part 31R and the second extension part 32R. In this step, the insertion part 33R is inserted into the gap formed between the first extension part 31R and the second extension part 32R on the one hand and the middle plate part 15 on the other hand. The first extension part 31R and the second extension part 32R are in contact with the upper surface of the insertion part 33R in a wider area T2 than the case where these extension parts extend only in the front-back direction. Therefore, it is possible to suppress the right inner wall part 11R from moving inward around the fold with the right wall top plate part 13R.

[0055] Finally, the limiting portions 16L, 16R are bent relative to the rear outer wall portion 12B, and the limiting portions 16L, 16R are stored in the storage portion 10 ( Figure 3 Then, the side plate portion 23, the upper plate portion 21 and the insertion portion 22 are bent relative to the bottom plate portion 14, and the insertion portion 22 is inserted into the insertion port G. Through the above steps, the box 1 can be assembled from a box material such as a plate-like cardboard or a corrugated cardboard.

[0056] 4. Summary

[0057] As described above, in the box 1 described in the present embodiment, there are provided a storage portion 10 defining a storage space S1 for storing articles and a cover portion 20 covering the upper side of the storage portion 10. The storage portion 10 has an inner peripheral wall portion 11 surrounding the storage space S1, an outer peripheral wall portion 12 surrounding the inner peripheral wall portion 11 and forming a gap with the inner peripheral wall portion 11, and a wall top plate portion 13 connected to the upper end of the outer peripheral wall portion 12 and the upper end of the inner peripheral wall portion 11 via a fold. 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 caused in the outer peripheral wall portion 12 due to the falling of the box 1, etc. from being transmitted to the storage space S1 defined by the inner peripheral wall portion 11. Therefore, it is possible to protect the articles stored in the storage space S1 from impact.

[0058] In addition, the peripheral wall portion 12 of the box 1 has a rear outer wall portion 12B, which can be opened and closed outwardly around the fold with the wall top plate portion. Therefore, a space (for example, space S2) for storing accessories of items can be ensured between the inner peripheral wall portion 11 (rear inner wall portion 11B) and the rear outer wall portion 12B. In addition, the cover portion 20 has a side plate portion 23, which covers the outer surface of the rear outer wall portion 12B when the cover portion 20 is closed. Thereby, when the cover portion 20 is closed, the rear outer wall portion 12B can be restricted from opening outward, and the accessories stored inside the rear outer wall portion 12B can be suppressed from falling to the outside.

[0059] It should be noted that the present invention is not limited to the above-mentioned embodiments. Although the shape in the plan view of the box 1 described in the embodiment is a square, the shape in the plan view of the box 1 may be, for example, a polygon such as a triangle or a pentagon, or may have an arc portion. In this case as well, by providing an inner peripheral wall portion 11 surrounding the storage space S1 and an outer peripheral wall portion 12 surrounding the inner peripheral wall portion 11 and forming a gap with the inner peripheral wall portion 11, the items stored in the storage space S1 can be protected from impact. In addition, a portion of the outer peripheral wall portion 12 (for example, the rear outer wall portion 12B) can be opened and closed to the outside, and the side plate portion 23 of the cover portion 20 covers the outer surface of the portion when the cover portion 20 is closed, so that the storage position of the item accessories can be ensured between the inner peripheral wall portion 11 and the outer peripheral wall portion 12, and the accessories can be suppressed from falling to the outside of the outer peripheral wall portion 12 when the cover portion 20 is closed.
