Summary of the Invention

Problems to be Solved by the Invention

[0004] The articles stored inside the box may be provided with accessories such as spare parts, warranty certificates, and instruction manuals. In the box, it is a problem to protect the articles stored inside the box from impact and to secure a storage place for the accessories. For example, it may be difficult to store the accessories in the same place as the space formed for storing the articles.

[0005] An object of the present disclosure is to provide a box that can protect articles stored inside the box from impact and secure a storage place for accessories.

Means for Solving the Problems

[0006] The box according to this disclosure is a box comprising a storage section having a defined storage space for storing articles, and a lid covering the upper part of the storage section. The storage section has an inner circumferential wall section surrounding the storage space and opening in the vertical direction, an outer circumferential wall section surrounding the inner circumferential wall section and forming a gap between it and the inner circumferential wall section, a top wall plate section connected to the upper end of the inner circumferential wall section and the upper end of the outer circumferential wall section via a fold, and a bottom plate section covering the lower part of the storage space and forming the bottom of the storage section. The outer circumferential wall section has a first outer wall section on one side in a first direction perpendicular to the vertical direction. The first outer wall section can be opened and closed to the outside of the storage section when the lid is open. The lid section has a side plate section that covers the outer surface of the first outer wall section when the lid is closed. This makes it possible to protect articles stored inside the box from impact and to secure storage space for accessories.

[0007] Furthermore, the box material according to this disclosure is a flat box material that can be formed by folding a box comprising a storage section having a storage space for storing articles, and a lid section covering the upper part of the storage section. When the box is formed, the storage section has an inner circumferential wall section surrounding the storage space and opening in the vertical direction, an outer circumferential wall section surrounding the inner circumferential wall section and forming a gap between it and the inner circumferential wall section, a top wall section connected to the upper end of the inner circumferential wall section and the upper end of the outer circumferential wall section via a fold, and a bottom plate section covering the lower part of the storage space and constituting the bottom of the storage section. When the box is formed, the outer circumferential wall section has a first outer wall section on one side in a first direction perpendicular to the vertical direction. When the box is formed and the lid section is open, the first outer wall section is openable and closable to the outside of the storage section. When the box is formed and the lid section is closed, the lid section has a side plate section covering the outer surface of the first outer wall section. This allows for the creation of a box that protects the contents stored inside from impact and provides a place for accessories. [Brief explanation of the drawing]

[0009] [1. Box Overview] The following describes a box 1, which is an example of an embodiment of the present disclosure. In the following description, the box 1 is described as being placed on a horizontal surface (not shown), such as the floor, and the directions X1 and X2 along the horizontal surface are referred to as the left direction and the right direction, respectively. Similarly, the directions Y1 and Y2 along the horizontal surface (directions perpendicular to the directions X1 and X2) are referred to as the front and rear, respectively. Furthermore, the directions Z1 and Z2 perpendicular to the horizontal surface are referred to as the up and down, respectively. However, these directions are defined to describe the shape and relative positional relationships of elements such as members and parts of the box 1, and do not limit the orientation of the box 1 with respect to the horizontal surface.

[0010] Figures 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 such as cardboard, corrugated cardboard, or plastic (see Figure 4). The box 1 has a storage section 10 in which items (not shown), such as replacement parts for an input device, are stored, and a lid section 20 connected to the storage section 10. Figure 1A shows the box 1 with the lid section 20 closed, and Figures 1B to 1E show the box 1 with the lid section 20 closed. E Figure 2 shows the lid 20 in the open position. Figure 3 is a front view of box 1 with the lid 20 closed. Figure 3 is a cross-sectional view taken along line III-III shown in Figure 2.

[0011] As shown in Figure 1A, with the lid 20 closed, the shape of the box 1 is a rectangular parallelepiped. As shown in Figure 1B, a storage space S1 is defined inside the storage section 10, which is recessed relative to the upper end of the storage section 10 (the wall top plate section 13, which will be described later). Articles are stored inside this storage space S1. As shown in Figures 1A and 1B, with the lid 20 closed in the box 1, the lid 20 covers the upper part of the storage section 10 and the storage space S1.

[0012] As shown in Figure 1B, the storage section 10 has an inner circumferential wall section 11 that surrounds the storage space S1 and is open in the vertical direction, and an outer circumferential wall section 12 that surrounds the inner circumferential wall section 11. The storage section 10 also has a top wall section 13 that is connected to the upper end of the inner circumferential wall section 11 and the upper end of the outer circumferential wall section 12 via a fold. Furthermore, as shown in Figures 2 and 3, the storage section 10 has a bottom plate section 14 that constitutes the bottom of the storage section 10, and a middle plate section 15 that is positioned above the bottom plate section 14 along the bottom plate section 14 and constitutes the bottom of the storage space S1. As shown in Figure 3, the bottom plate section 14 covers the lower side of the storage space S1. The outer circumferential wall section 12 is positioned along the edge of the bottom plate section 14 and surrounds the bottom plate section 14. The storage space S1 is located in the center of the storage section 10 in a plan view, and a gap (for example, the gaps shown by arrows D1 and D2 in Figure 3) is formed between the inner circumferential wall 11 surrounding the storage space S1 and the outer circumferential wall 12 surrounding the bottom plate 14. The formation of a gap between the inner circumferential wall 11 and the outer circumferential wall 12 suppresses the transmission of impacts generated on the outer circumferential wall 12 due to the box 1 being dropped, etc., to the storage space S1, thereby protecting the items stored in the storage space S1 from impact.

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

[0014] In a 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 creases respectively, 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 creases respectively, 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 creases respectively, 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 creases respectively. 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 their adjacent arrangement, the wall top plate portion 13 is formed in a rectangular frame shape in a plan view. Also, between the front outer wall portion 12F and the front wall top plate portion 13F, along their creases, a front end portion of the lid portion 20 (insertion portion 22 described later) It is inserted an insertion opening 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 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 put in and taken out inside the space S2. Further, regulation portions 16L and 16R that are bent with respect to the rear outer wall portion 12B are formed at the left and right ends of the rear outer wall portion 12B. By the edges E1 and E2 (see FIG. 1E) of the regulation portions 16L and 16R hitting 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 put in and taken out inside the space S3. Further, 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 fall 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 part 12BWith the fold as the center, it can move upward more than the front wall top section 13F, the left wall top section 13L, and the right wall top section 13R. In this way, when the rear outer wall section 12B opens outward, the rear wall top section 13B, which is connected to the rear outer wall section 12B, moves upward, making it easier to open the rear outer wall section 12B compared to a case where only the rear outer wall section 12B moves.

[0019] As shown in Figures 1A and 1B, the lid 20 has an upper plate portion 21 that covers the storage space S1 and the top wall portion 13 of the storage unit 10 when the lid 20 is closed, an insertion portion 22 connected to the front end of the upper plate portion 21 via a fold, and a side plate portion 23 connected to the rear end of the upper plate portion 21 via a fold. When the lid 20 is closed, the upper plate portion 21 of the lid 20 covers the entire storage unit 10 in a plan view. In addition, the insertion portion 22 of the lid 20 is inserted into the insertion opening G when the lid 20 is closed, thereby preventing the lid 20 from opening without external force.

[0020] As shown in Figure 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 Figure 3, when the lid portion 20 is closed, the side plate portion 23 is in contact with the outer surface of the rear outer wall portion 12B and covers the outer surface of the rear outer wall portion 12B. When the lid portion 20 is closed, the side plate portion 23 of the lid portion 20 covers the outer surface of the rear outer wall portion 12B, thereby preventing the rear outer wall portion 12B from opening outwards. This prevents accessories stored in space S2 and space S3 from falling out of the rear outer wall portion 12B.

[0021] Furthermore, as shown in Figure 1B, the side plate portion 23 has an arc-shaped cut K. 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 relative to the top plate portion 21 at an angle different from the angle made between the top plate portion 21 and the side plate portion 23. The cantilever plate portion 24 may protrude to the rear of the side plate portion 23 when the lid portion 20 is closed, for example. When the box 1 is stored in the outer box (not shown), the box 1 can be pulled out from the outer box by pulling the cantilever plate portion 24 of the box 1 backward.

[0022] [2. Relationship with unfolded diagrams] Figure 4 is a plan view of the flat box material that makes up box 1. Box 1 is formed by folding the box material shown in Figure 4 along the folds. In Figure 4 and Figures 5A to 5D described later, dotted lines indicate mountain folds, and dashed lines indicate valley folds.

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

[0024] Furthermore, in the unfolded view shown in Figure 4, the rear inner wall 11B, front inner wall 11F, left inner wall 11L, and right inner wall 11R that constitute the inner circumferential wall 11 are formed at positions separate from each other. Of the wall portions that constitute the inner circumferential wall 11, the rear inner wall 11B and the front inner wall 11F are connected to the front and rear ends of the middle plate 15 via folds, respectively, but the left inner wall 11L and the right inner wall 11R are not connected to the middle plate 15. In this way, it becomes possible to assemble the box 1 from a single sheet of plate-shaped box material.

[0025] As shown in Figure 4, support pieces 34L and 34R are formed at the left and right ends of the middle plate portion 15. The support pieces 34L and 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, forming a space S3 (see Figure 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 (distance between support pieces 34L and 34R) is equal to the width D4 of the bottom plate portion 14 in the left-right direction. In this way, sufficient width in the left-right direction can be secured in the space S3 between the bottom plate portion 14 and the middle plate portion 15.

[0026] As shown in Figure 4, the first extensions 31L and 31R are connected to the rear inner wall 11B via folds. The first extensions 31L and 31R are connected to the left and right ends of the rear inner wall 11B, respectively. The second extensions 32L and 32R are connected to the front inner wall 11F via folds. The second extensions 32L and 32R are connected to the left and right ends of the front inner wall 11F, respectively. The first extensions 31L and 31R have a recess C1 on their outer edge, and the second extensions 32L and 32R have a recess C2 on their outer edge. In the example shown in Figure 4, the first extensions 31L and 31R and the second extensions 32L and 32R are formed in the same shape. The functions of the first extensions 31L and 31R and the second extensions 32L and 32R will be described later.

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

[0028] In the unfolded view shown in Figure 4, the rear outer wall 12B, front outer wall 12F, left outer wall 12L, and right outer wall 12R that constitute the outer perimeter wall 12 are formed at positions separate from each other. Of the walls that constitute the outer perimeter wall 12, the front outer wall 12F, left outer wall 12L, and right outer wall 12R are connected to the bottom plate 14 via folds. In the outer perimeter wall 12, the rear outer wall 12B is not connected to the left outer wall 12L, the right outer wall 12R, or the bottom plate 14. Therefore, when the box 1 is assembled and the lid 20 is open, the rear outer wall 12B can be opened and closed to the outside of the storage section 10.

[0029] Furthermore, in the unfolded view shown in Figure 4, the rear wall top section 13B, front wall top section 13F, left wall top section 13L, and right wall top section 13R that constitute the wall top section 13 are formed at positions separate from each other. In the wall top section 13, the rear wall top section 13B is not connected to the left wall top section 13L and the right wall top section 13R. Therefore, as shown in Figure 1E, when the rear outer wall section 12B opens, the rear wall top section 13B, which is connected to the rear outer wall section 12B, can move upward relative to the front wall top section 13F, the left wall top section 13L, and the right wall top section 13R.

[0030] [3. Assembling the box] Figures 5A to 5D illustrate the assembly method of box 1. Note that the cut K and cantilever plate section 24 shown in Figure 4 are omitted in Figures 5A to 5D.

[0031] First, as shown in Figure 5A, in a flat box-shaped material, the front outer wall portion 12F is bent relative to the bottom plate portion 14, and the front 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 top plate portion 13B, the rear inner wall portion 11B is bent relative to the rear top plate portion 13B and the middle plate portion 15, and the front inner wall portion 11F is bent relative to the front top plate portion 13F and the middle plate portion 15. In this process, the front outer wall portion 12F, the front top plate portion 13F, the front inner wall portion 11F, the middle plate portion 15, the rear inner wall portion 11B, the rear top plate portion 13B, and the rear outer wall portion 12B are bent in this order. From the front They are lined up at the back. Note that in Figure 5A, the left and right wall top panels 13L, 13R, the inner wall panels 11L, 11R, and the insertion parts 33L, 33R are also folded, but these may be folded in a later step.

[0032] Next, as shown in Figures 5A and 5B, the first extensions 31L and 31R are bent forward relative to the rear inner wall 11B, and the second extensions 32L and 32R are bent backward relative to the front inner wall 11F. At this time, the first extension 31L and the second extension 32L are fixed together by hooking the recess C2 formed on the edge of the second extension 32L into the recess C1 formed on the edge of the left first extension 31L. Similarly, the first extension 31R and the second extension 32R are fixed together by hooking the recess C2 formed on the edge of the second extension 32R into the recess C1 formed on the edge of the right first extension 31R. In addition, the support pieces 34L and 34R are bent downward relative to the middle plate 15.

[0033] Figure 5C shows a top view of box 1 during assembly, as shown in Figure 5B. As shown in Figure 5C, the first extension 31L and the second extension 32L on the left side are interlocked, and these extensions extend diagonally with respect to the front-to-back direction. Similarly, the first extension 31R and the second extension 32R on the right side are interlocked, and these extensions extend diagonally with respect to the front-to-back direction. As a result, in a plan view of box 1, a hexagon is formed with the first extensions 31L, 31R, the second extensions 32L, 32R, the rear inner wall 11B, and the front inner wall 11F as its sides. Here, a gap (second gap) is formed between the interlocked first extensions 31L and 2 extensions 32L and the middle plate 15. A gap (second gap) is also formed between the interlocked first extensions 31R and 2 extensions 32R and the middle plate 15.

[0034] Next, as shown in Figures 5B and 5D, the left outer wall portion 12L, the left wall top plate portion 13L, the left inner wall portion 11L, and the insertion portion 33L are bent to form the left side of the storage portion 10. In this process, the left first extension portion 31L and the second extension portion 32L are positioned below the left wall top plate portion 13L, and the left inner wall portion 11L is positioned inward from the first extension portion 31L and the second extension portion 32L. In this process, the insertion portion 33L is inserted into the gap (second gap) formed between the first extension portion 31L and the second extension portion 32L and the middle plate portion 15. As mentioned above, since the first extension portion 31L and the second extension portion 32L extend diagonally with respect to the front-rear direction, they contact the upper surface of the insertion portion 33L over a wider area T1 than if these extension portions extended only in the front-rear direction. Therefore, the insertion portion 33L can be effectively prevented from coming out of the gap formed between the first extension portion 31L and the second extension portion 32L and the middle plate portion 15. This prevents the left inner wall portion 11L from moving inward around the fold with the left wall top plate portion 13L.

[0035] Similarly, the right side of the storage section 10 is formed by folding the right outer wall section 12R, the right wall top section 13R, the right inner wall section 11R, and the insertion section 33R. In this process, the right first extension section 31R and the second extension section 32R are positioned below the right wall top section 13R, and the right inner wall section 11R is positioned inward of the first extension section 31R and the second extension section 32R. In this process, the insertion section 33R is inserted into the gap formed between the first extension section 31R and the second extension section 32R and the middle plate section 15. The first extension section 31R and the second extension section 32R contact the upper surface of the insertion section 33R over a wider area T2 than if these extension sections extended only in the front-rear direction. This prevents the right inner wall section 11R from moving inward around the fold with the right wall top section 13R.

[0036] Finally, the restricting parts 16L and 16R are folded relative to the rear outer wall part 12B, and the restricting parts 16L and 16R are stored inside the storage part 10 (inside the space S2 shown in Figure 3). Then, the side plate part 23, the top plate part 21, and the insertion part 22 are folded relative to the bottom plate part 14, and the insertion part 22 is inserted inside the insertion opening G. Through these steps, the box 1 can be assembled from box material such as cardboard or corrugated cardboard.

[0037] [4. Summary] As described above, the box 1 described in this embodiment comprises a storage section 10 which defines a storage space S1 for storing articles, and a lid section 20 which covers the upper side of the storage section 10. The storage section 10 has an inner circumferential wall section 11 which surrounds the storage space S1, an outer circumferential wall section 12 which surrounds the inner circumferential wall section 11 and forms a gap between it and the inner circumferential wall section 11, and a top wall section 13 which is connected to the upper end of the outer circumferential wall section 12 and the upper end of the inner circumferential wall section 11 via a fold. By forming a gap between the outer circumferential wall section 12 and the inner circumferential wall section 11, it is possible to suppress the transmission of impacts generated on the outer circumferential wall section 12 due to the box 1 being dropped or the like to the storage space S1 defined by the inner circumferential wall section 11. Therefore, articles stored in the storage space S1 can be protected from impact.

[0038] Furthermore, the outer wall portion 12 of box 1 is the wall top portion 13 The lid has a rear outer wall portion 12B that can be opened and closed outward around a fold. This ensures that a space (e.g., space S2) for storing accessories of the article is secured between the inner circumferential wall portion 11 (rear inner wall portion 11B) and the rear outer wall portion 12B. The lid portion 20 also 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. This prevents the rear outer wall portion 12B from opening outward when the lid portion 20 is closed, and prevents accessories stored inside the rear outer wall portion 12B from falling out.

[0039] It should be noted that the present invention is not limited to the embodiments described above. The shape of the box 1 described in the embodiments was a rectangle in plan view, but the shape of the box 1 in plan view may be a polygon such as a triangle or a pentagon, or it may have an arc-shaped portion. In this case as well, by providing an inner circumferential wall portion 11 surrounding the storage space S1 and an outer circumferential wall portion 12 surrounding the inner circumferential wall portion 11 and forming a gap between it and the inner circumferential wall portion 11, the articles stored in the storage space S1 can be protected from impact.
