Description

Boxes and box materials

This disclosure relates to boxes and box materials.

Patent Document 1 below discloses an input device used to operate a game device. Items such as parts of the input device (e.g., replacement parts) are shipped stored inside a box with a lid. By forming such a box by folding a flat member such as corrugated cardboard, the manufacturing costs of the box can be reduced.

International Publication No. 2014/061362

In some cases, items stored in a box come with accessories such as spare parts, warranties, and instruction manuals. The challenge with a box is to protect the items stored inside the box from impact while also ensuring a place to store the accessories. For example, it can be difficult to store the accessories in the same space that is created to store the items.

The objective of this disclosure is to provide a box that can protect items stored inside the box from impact and provide storage space for accessories.

The box according to the present disclosure is a box including a storage section in which a storage space for storing items is defined, and a lid section covering the upper side of the storage section. The storage section includes an inner wall section that surrounds the storage space and opens in the vertical direction, an outer wall section that surrounds the inner wall section and forms a gap between the inner wall section and the outer wall section, a wall top plate section that is connected to the upper end of the inner wall section and the upper end of the outer wall section via a fold, and a bottom plate section that covers the lower side of the storage space and constitutes the bottom of the storage section. The outer 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 section is open. The lid section has a side plate section that covers the outer surface of the first outer wall section when the lid section is closed. This makes it possible to protect items stored inside the box from impact and to secure a storage space for accessories.

The box material according to the present disclosure is a flat box material that can be formed by folding a box including a storage section in which a storage space for storing items is defined and a lid section that covers the upper side of the storage section. When the box is formed, the storage section has an inner wall section that surrounds the storage space and opens in the vertical direction, an outer wall section that surrounds the inner wall section and forms a gap between the inner wall section and the outer wall section, a wall top plate section that is connected to the upper end of the inner wall section and the upper end of the outer wall section via a fold, and a bottom plate section that covers the lower side of the storage space and constitutes the bottom of the storage section. When the box is formed, the outer 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 can be opened and closed 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 that covers the outer surface of the first outer wall section. This makes it possible to create a box that protects items stored inside from impacts and provides storage space for accessories.

[1. Overview of the box]
The box 1, which is an example of an embodiment of the present disclosure, will be described below. In the following description, a state in which the box 1 is placed on a horizontal plane (not shown) such as a floor surface will be described, and the directions X1 and X2 along the horizontal plane will be referred to as the left direction and the right direction, respectively. Similarly, the directions Y1 and Y2 along the horizontal plane (directions perpendicular to the directions X1 and X2) will be referred to as the front and the rear, respectively. In addition, the directions Z1 and Z2 perpendicular to the horizontal plane will be referred to as the up and down, respectively. However, these directions are defined to explain the shapes and relative positional relationships of elements such as members and parts of the box 1, and do not limit the attitude of the box 1 with respect to the horizontal plane.

FIGS. 1A to 1E are perspective views of box 1, which is an example of an embodiment of the present disclosure. Box 1 is formed by folding a flat box material (see FIG. 4) such as cardboard, corrugated cardboard, or plastic. 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. FIG. 1A shows box 1 with lid section 20 closed, and FIGS. 1B to 1D show box 1 with lid section 20 open. FIG. 2 is a front view of box 1 with lid section 20 closed. FIG. 3 is a cross-sectional view taken along line III-III shown in FIG. 2.

As shown in FIG. 1A, when the lid portion 20 is closed, the shape of the box 1 is a rectangular parallelepiped. As shown in FIG. 1B, inside the storage section 10, a storage space S1 is defined that is recessed relative to the upper end of the storage section 10 (the wall top portion 13 described below). Items are stored inside this storage space S1. As shown in FIG. 1A and FIG. 1B, when the lid portion 20 of the box 1 is closed, the lid portion 20 covers the upper side of the storage section 10 and the storage space S1.

As shown in FIG. 1B, the storage section 10 has an inner wall portion 11 that surrounds the storage space S1 and opens in the vertical direction, and an outer wall portion 12 that surrounds the inner wall portion 11. The storage section 10 also has a wall top plate portion 13 that is connected to the upper end of the inner wall portion 11 and the upper end of the outer wall portion 12 via a fold. As shown in FIG. 2 and FIG. 3, the storage section 10 has a bottom plate portion 14 that constitutes the bottom of the storage section 10, and a middle plate portion 15 that is arranged above and along 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 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 located in the center of the storage section 10 in a plan view, and a gap (for example, the gap indicated by arrows D1 and D2 in FIG. 3) is formed between the inner wall portion 11 surrounding the storage space S1 and the outer wall portion 12 surrounding the bottom plate portion 14. By forming a gap between the inner wall portion 11 and the outer wall portion 12, an impact generated on the outer wall portion 12 due to, for example, the dropping of the box 1 is prevented from being transmitted to the storage space S1, and the items stored in the storage space S1 can be protected from the impact.

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

Furthermore, the storage space S1 is rectangular in plan view, and the inner 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 Figures 1B and 1C. The rear inner wall portion 11B is formed on the rear side of the inner wall portion 11, the front inner wall portion 11F is formed on the front side of the inner wall portion 11, the left inner wall portion 11L is formed on the left side of the inner wall portion 11, and the right inner wall portion 11R is formed on the right side of the inner wall portion 11.

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, 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, 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, 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. 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 being adjacent to each other, the wall top plate portion 13 is formed into a rectangular frame shape in a plan view. Additionally, between the front outer wall portion 12F and the front wall top plate portion 13F, an insertion opening G for the front end portion of the lid portion 20 (the insertion portion 22 described below) is formed along these folds.

1C and 1D, the rear outer wall 12B formed on the rear side of the outer peripheral wall 12 can be opened and closed outward around the fold with the wall top plate 13 (more specifically, the rear wall top plate 13B) when the lid 20 is open. As shown in FIG. 3, inside the storage section 10, a space S2 different from the storage space S1 is defined by the rear inner wall 11B, the rear outer wall 12B, the rear wall top plate 13B, and the bottom plate 14. By opening the rear outer wall 12B outward relative to the storage section 10, it becomes possible to insert and remove accessories such as spare parts, warranty cards, and instruction manuals into and from the inside of the space S2. In addition, the left and right ends of the rear outer wall 12B are formed with restricting

portions

16L and 16R that are bent relative to the rear outer wall 12B. The edges E1, E2 (see FIG. 1E) of the restricting

portions

16L, 16R come into contact with the underside of the wall top plate portion 13, thereby restricting the rear outer wall portion 12B from moving inwardly of the storage portion 10.

As shown in FIG. 3, the middle plate 15 is disposed above the bottom plate 14, and a flat space S3 is defined by the gap between the middle plate 15 and the bottom plate 14. Space S3 is connected to space S2, and the rear outer wall 12B opens outward relative to the storage section 10, allowing accessories such as warranty cards and instruction manuals to be inserted and removed from inside space S3. In addition, the formation of space S3 between the storage space S1 and the bottom plate 14 prevents any impact on the bottom plate 14, such as when the box 1 is dropped, from being transmitted to the storage space S1.

As shown in FIG. 1C, when the rear outer wall portion 12B is closed, the rear wall top portion 13B, front wall top portion 13F, left wall top portion 13L, and right wall top portion 13R constituting the wall top 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 portion 13B (connection end portion) connected to the rear outer wall portion 12B can move upward beyond the front wall top portion 13F, left wall top portion 13L, and right wall top portion 13R, centered on the fold with the rear wall top portion 13B. In this way, when the rear outer wall portion 12B opens outward, the rear wall top 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 when only the rear outer wall portion 12B moves.

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

As shown in FIG. 1C, the side plate 23 of the lid 20 is connected to the bottom plate 14 via a fold. As shown in FIG. 3, when the lid 20 is closed, the side plate 23 contacts the outer surface of the rear outer wall 12B and covers the outer surface of the rear outer wall 12B. When the lid 20 is closed, the side plate 23 of the lid 20 covers the outer surface of the rear outer wall 12B, thereby preventing the rear outer wall 12B from opening outward. This prevents accessories stored in spaces S2 and S3 from falling out to the outside of the rear outer wall 12B.

Also, as shown in FIG. 1B, the side plate portion 23 has an arc-shaped slit K formed therein. Both ends of the slit K are connected to a crease with the upper plate portion 21, and the cantilever plate portion 24 defined by the slit K and the crease can bend with respect to the upper plate portion 21 at an angle different from the angle between the upper plate portion 21 and the side plate portion 23. For example, the cantilever plate portion 24 may protrude rearward from the side plate portion 23 when the lid portion 20 is closed. When the box 1 is stored in an outer box (not shown), the cantilever plate portion 24 of the box 1 can be pulled rearward from the outer box.

[2. Relationship with the development diagram]
Fig. 4 is a plan view of a flat box material constituting box 1. Box 1 is formed by folding the box material shown in Fig. 4 along the creases. In Fig. 4 and Figs. 5A to 5D described below, dotted lines indicate mountain folds, and dashed lines indicate valley folds.

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 creases. 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 creases, the left wall top plate portion 13L is connected to the left inner wall portion 11L and the left outer wall portion 12L via creases, 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 creases.

In addition, in the development view shown in FIG. 4, the rear inner wall portion 11B, front inner wall portion 11F, left inner wall portion 11L, and right inner wall portion 11R that make up the inner wall portion 11 are formed at positions separated from one another. Of the walls that make up the inner 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. In this way, it becomes possible to assemble the box 1 from a single plate-shaped box material.

As shown in Figure 4,

support pieces

34L, 34R are formed on the left and right ends of the middle plate 15.

Support pieces

34L, 34R are bent downward relative to the middle plate 15 and contact the bottom plate 14 to support the middle plate 15, forming a space S3 (see Figure 3) between the bottom plate 14 and the middle plate 15. The width D3 of the middle plate 15 in the left-right direction (the distance between

support pieces

34L and 34R) is equal to the width D4 of the bottom plate 14 in the left-right direction. This ensures that the space S3 between the bottom plate 14 and the middle plate 15 is sufficiently wide in the left-right direction.

As shown in FIG. 4, the

first extensions

31L, 31R are connected to the rear inner wall 11B via creases. The

first extensions

31L, 31R are connected to the left and right ends of the rear inner wall 11B, respectively. The

second extensions

32L, 32R are connected to the front inner wall 11F via creases. The

second extensions

32L, 32R are connected to the left and right ends of the front inner wall 11F, respectively. The

first extensions

31L, 31R have a recess C1 on their outer edges, and the

second extensions

32L, 32R have a recess C2 on their outer edges. In the example shown in FIG. 4, the

first extensions

31L, 31R and the

second extensions

32L, 32R are formed in the same shape. The functions of the

first extensions

31L, 31R and the

second extensions

32L, 32R will be described later.

As shown in FIG. 4, the left inner wall portion 11L and the right inner wall portion 11R are connected by

insertion portions

33L, 33R via folds. The insertion portion 33L is formed on the side of the left inner wall portion 11L opposite the side on which 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 the side on which the right wall top plate portion 13R is formed. The function of the

insertion portions

33L, 33R will be described later.

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

In addition, in the development view shown in FIG. 4, the rear wall top plate portion 13B, front wall top plate portion 13F, left wall top plate portion 13L, and 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, 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, so that when the rear outer wall portion 12B opens, as shown in FIG. 1E, the rear wall top plate portion 13B that is connected to the rear outer wall portion 12B can move upward relative to the front wall top plate portion 13F, left wall top plate portion 13L, and right wall top plate portion 13R.

3. Assembling the Box
5A to 5D are diagrams for explaining a method of assembling the box 1. Note that in Fig. 5A to 5D, the cut K and the cantilever plate portion 24 shown in Fig. 4 are omitted.

First, as shown in Figure 5A, in a flat box material, the front outer wall portion 12F is folded against the bottom plate portion 14, and the front wall top plate portion 13F is folded against the front outer wall portion 12F. Then, the rear outer wall portion 12B is folded against the rear wall top plate portion 13B, the rear inner wall portion 11B is folded against the rear wall top plate portion 13B and the middle plate portion 15, and the front inner wall portion 11F is folded against the front wall top plate portion 13F and the middle plate portion 15. In this process, the front outer wall portion 12F, front wall top plate portion 13F, front inner wall portion 11F, middle plate portion 15, rear inner wall portion 11B, rear wall top plate portion 13B, and rear outer wall portion 12B are lined up rearward in that order. In FIG. 5A, the left and right wall tops 13L, 13R,

inner wall portions

11L, 11R, and

insertion portions

33L, 33R are also folded, but these may be folded in a later process.

Next, as shown in Figures 5A and 5B, the

first extensions

31L, 31R are bent forward relative to the rear inner wall 11B, and the

second extensions

32L, 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 by hooking the recess C2 formed on the edge of the second extension 32L to the recess C1 formed on the edge of the first extension 31L on the left side. Similarly, the first extension 31R and the second extension 32R are fixed by hooking the recess C2 formed on the edge of the second extension 32R to the recess C1 formed on the edge of the first extension 31R on the right side. In addition, the

support pieces

34L, 34R are bent downward relative to the middle plate 15.

FIG. 5C shows the box 1 in the process of assembly shown in FIG. 5B, viewed from above. As shown in FIG. 5C, when the first extension portion 31L and the second extension portion 32L on the left side are interlocked with each other, these extension portions extend in a diagonal direction relative to the front-to-rear direction. Also, when the first extension portion 31R and the second extension portion 32R on the right side are interlocked with each other, these extension portions extend in a diagonal direction relative to the front-to-rear direction. As a result, in a plan view of the box 1, a hexagon is formed with the

first extension portions

31L, 31R, the

second extension portions

32L, 32R, the rear inner wall portion 11B, and the front inner wall portion 11F as its sides. Here, a gap (second gap) is formed between the first extension portion 31L and the second extension portion 32L, which are interlocked 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, which are interlocked with each other, and the middle plate portion 15.

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 folded to form the left portion of the storage portion 10. Through this process, the first extension portion 31L and the second extension portion 32L on the left side are positioned below the left wall top plate portion 13L, and the left inner wall portion 11L is positioned inside the first extension portion 31L and the second extension portion 32L. Also, during 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 described above, the first extension portion 31L and the second extension portion 32L extend in a diagonal direction relative to the front-to-rear direction, and therefore contact the upper surface of the insertion portion 33L in a region T1 that is wider than when these extension portions extend only in the front-to-rear direction. This effectively prevents the insertion portion 33L 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 crease with the left wall top plate portion 13L.

Similarly, the right outer wall 12R, the right wall top plate 13R, the right inner wall 11R, and the insertion portion 33R are folded to form the right portion of the storage section 10. In this process, the first extension 31R and the second extension 32R on the right side are positioned below the right wall top plate 13R, and the right inner wall 11R is positioned inside the first extension 31R and the second extension 32R. In this process, the insertion portion 33R is inserted into the gap formed between the first extension 31R and the second extension 32R and the middle plate 15. The first extension 31R and the second extension 32R come into contact with the upper surface of the insertion portion 33R in a region T2 that is wider than when these extensions extend only in the front-rear direction. This makes it possible to prevent the right inner wall 11R from moving inward around the fold with the right wall top plate 13R.

Finally, the restricting

portions

16L, 16R are folded against the rear outer wall portion 12B, and the restricting

portions

16L, 16R are stored inside the storage portion 10 (inside the space S2 shown in FIG. 3). Then, the side plate portion 23, the top plate portion 21, and the insertion portion 22 are folded against the bottom plate portion 14, and the insertion portion 22 is inserted inside the insertion opening G. Through these steps, the box 1 can be assembled from box materials such as plate-shaped cardboard or corrugated cardboard.

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

The outer peripheral wall 12 of the box 1 also has a rear outer wall 12B that can be opened and closed outward around a crease with the wall top plate. This allows a space (e.g., space S2) for storing accessories of an item to be secured between the inner peripheral wall 11 (rear inner wall 11B) and the rear outer wall 12B. The lid 20 also has a side plate 23 that covers the outer surface of the rear outer wall 12B when the lid 20 is closed. This prevents the rear outer wall 12B from opening outward when the lid 20 is closed, and prevents accessories stored inside the rear outer wall 12B from falling out to the outside.

The present invention is not limited to the above embodiment. The shape of the box 1 described in the embodiment is 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 may have an arc-shaped portion. Even in this case, the inner wall portion 11 surrounding the storage space S1 and the outer wall portion 12 surrounding the inner wall portion 11 and forming a gap between the inner wall portion 11 can be provided to protect the items stored in the storage space S1 from impact. In addition, by making a part of the outer wall portion 12 (for example, the rear outer wall portion 12B) openable and closable outward, and covering the outer surface of the part with the side plate portion 23 of the lid portion 20 in a closed state, a storage space for accessories of the items can be secured between the inner wall portion 11 and the outer wall portion 12, and the accessories can be prevented from falling out to the outside of the outer wall portion 12 with the lid portion 20 closed.
