SUMMARY

Technical Problem

The articles stored in the box are provided with accessories such as spare parts, warranties, and instruction manuals in some cases. The box is required to protect the articles stored inside the box from a shock and to secure a storage place for the accessories. For example, it is difficult in some cases to store the accessories in the same place as the space formed to store the articles.

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

Solution to Problem

A box according to the present disclosure is a box provided with a storage section in which a storage space for storing articles is defined and a lid section that covers an upper side of the storage section. The storage section has an inner circumferential wall section that surrounds the storage space and opens in an up-down direction, an outer circumferential wall section that surrounds the inner circumferential wall section and forms a gap with the inner circumferential wall section, a wall top plate section that is connected to an upper end of the inner circumferential wall section and an upper end of the outer circumferential wall section via creases, and a bottom plate section that covers a lower side of the storage space and configures a bottom section 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 up-down direction. The first outer wall section is able to be opened and closed to an outside of the storage section in a state in which the lid section is opened. The lid section has a side plate section that covers an outer surface of the first outer wall section in a state in which the lid section is closed. According to this, it is possible to protect the articles stored inside the box from a shock and to secure a storage place for accessories.

In addition, a box material according to the present disclosure is a flat plate-shaped box material that is able to form, by being bent, a box provided with a storage section in which a storage space for storing articles is defined and a lid section that covers an upper side of the storage section. In a state in which the box is formed, the storage section has an inner circumferential wall section that surrounds the storage space and opens in an up-down direction, an outer circumferential wall section that surrounds the inner circumferential wall section and forms a gap with the inner circumferential wall section, a wall top plate section that is connected to an upper end of the inner circumferential wall section and an upper end of the outer circumferential wall section via creases, and a bottom plate section that covers a lower side of the storage space and configures a bottom section of the storage section. In the state in which 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 up-down direction. In a state in which the box is formed and the lid section is opened, the first outer wall section is able to be opened and closed to an outside of the storage section. In a state in which the box is formed and the lid section is closed, the lid section has a side plate section that covers an outer surface of the first outer wall section. According to this, it is possible to form a box that protects the articles stored inside the box from a shock and secures a storage place for accessories.

DESCRIPTION OF EMBODIMENT

1. Overview of Box

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

FIG. 1A to FIG. 1E are perspective views of the box 1 that is an example of the embodiment of the present disclosure. The box 1 is formed by folding a flat plate-shaped box material (see FIG. 4) such as cardboard, corrugated cardboard, or plastic. The box 1 has a storage section 10 for storing articles (not illustrated) such as replacement parts of an input device and a lid section 20 connected to the storage section 10. FIG. 1A depicts a state in which the lid section 20 of the box 1 is closed, and FIG. 1B to FIG. 1D depict states in which the lid section 20 is opened. FIG. 2 is a front view of the box 1 in a state in which the lid section 20 is closed. FIG. 3 is a cross-sectional view taken along a line III-III depicted in FIG. 2.

As depicted in FIG. 1A, in a state in which the lid section 20 is closed, the box 1 has a rectangular parallelepiped shape. As depicted in FIG. 1B, a storage space S1 having a shape recessed with respect to an upper end (a wall top plate section 13 to be described later) of the storage section 10 is defined inside the storage section 10. Articles are stored inside the storage space S1. As depicted in FIG. 1A and FIG. 1B, in a state in which the lid section 20 of the box 1 is closed, the lid section 20 covers the upper sides of the storage section 10 and the storage space S1.

As depicted in FIG. 1B, the storage section 10 has an inner circumferential wall section 11 that surrounds the storage space S1 and opens in the up-down direction and an outer circumferential wall section 12 that surrounds the inner circumferential wall section 11. In addition, the storage section 10 has a wall top plate section 13 that is connected to an upper end of the inner circumferential wall section 11 and an upper end of the outer circumferential wall section 12 via creases. In addition, as depicted in FIG. 2 and FIG. 3, the storage section 10 has a bottom plate section 14 configuring a bottom section of the storage section 10 and a middle plate section 15 that is arranged above the bottom plate section 14 along the bottom plate section 14 and configures a bottom section of the storage space S1. As depicted in FIG. 3, the bottom plate section 14 covers the lower side of the storage space S1. The outer circumferential wall section 12 is arranged along the edge of the bottom plate section 14 and surrounds the bottom plate section 14. The storage space S1 is positioned at the center of the storage section 10 in plan view, and gaps (for example, gaps indicated by arrows D1 and D2 in FIG. 3) are formed between the inner circumferential wall section 11 surrounding the storage space S1 and the outer circumferential wall section 12 surrounding the bottom plate section 14. Since the gaps are formed between the inner circumferential wall section 11 and the outer circumferential wall section 12, a shock caused in the outer circumferential wall section 12 due to the falling of the box 1 or the like is suppressed from being transmitted to the storage space S1, and the articles stored in the storage space S1 can be protected from the shock.

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

In addition, the storage space S1 is rectangular in plan view, and the inner circumferential wall section 11 has a rear inner wall section 11B (first inner wall section), a front inner wall section 11F (second inner wall section), a left inner wall section 11L (third inner wall section), and a right inner wall section 11R (fourth inner wall section) as depicted in FIG. 1B and FIG. 1C. The rear inner wall section 11B is formed on the rear side of the inner circumferential wall section 11, the front inner wall section 11F is formed on the front side of the inner circumferential wall section 11, the left inner wall section 11L is formed on the left side of the inner circumferential wall section 11, and the right inner wall section 11R is formed on the right side of the inner circumferential wall section 11.

The wall top plate section 13 has a rear wall top plate section 13B (first wall top plate section) that is connected to each of the rear inner wall section 11B and the rear outer wall section 12B via a crease, a front wall top plate section 13F (second wall top plate section) that is connected to each of the front inner wall section 11F and the front outer wall section 12F via a crease, a left wall top plate section 13L (third wall top plate section) that is connected to each of the left inner wall section 11L and the left outer wall section 12L via a crease, and a right wall top plate section 13R (fourth wall top plate section) that is connected to each of the right inner wall section 11R and the right outer wall section 12R via a crease. All of the rear wall top plate section 13B, the front wall top plate section 13F, the left wall top plate section 13L, and the right wall top plate section 13R are trapezoidal. Since these are adjacent to each other, the wall top plate section 13 is formed into a square frame in plan view. In addition, an insertion port G into which a front end (an insertion section 22 to be described later) of the lid section 20 is inserted is formed between the front outer wall section 12F and the front wall top plate section 13F along these creases.

As depicted in FIG. 1C and FIG. 1D, the rear outer wall section 12B formed on the rear side of the outer circumferential wall section 12 can be opened and closed to the outside about a crease with the wall top plate section 13 (more specifically, the rear wall top plate section 13B) in a state in which the lid section 20 is opened. As depicted in FIG. 3, a space S2 different from the storage space S1 is defined inside the storage section 10 by the rear inner wall section 11B, the rear outer wall section 12B, the rear wall top plate section 13B, and the bottom plate section 14. The rear outer wall section 12B is opened to the outside relative to the storage section 10, so that accessories such as spare parts, warranties, and instruction manuals of the articles can be taken in and out of the space S2. In addition, restriction sections 16L and 16R bent relative to the rear outer Wall section 12B are formed at a left end and a right end of the rear outer wall section 12B, respectively. Edge sections E1 and E2 (see FIG. 1E) of the restriction sections 16L and 16R contact a lower surface of the wall top plate section 13, so that the rear outer wall section 12B can be restricted from being moved to the inside of the storage section 10.

As depicted in FIG. 3, the middle plate section 15 is arranged above the bottom plate section 14, and a flat plate-shaped space S3 is defined by a gap between the middle plate section 15 and the bottom plate section 14. The space S3 is connected to the space S2, and the rear outer wall section 12B is opened to the outside relative to the storage section 10, so that accessories such as warranties and instruction manuals can be taken in and out of the space S3. In addition, since the space S3 is formed between the storage space S1 and the bottom plate section 14, a shock caused in the bottom plate section 14 due to the falling of the box 1 or the like can be suppressed from being transmitted to the storage space S1.

As depicted in FIG. 1C, in a state in which the rear outer wall section 12B is closed, the rear wall top plate section 13B, the front wall top plate section 13F, the left wall top plate section 13L, and the right wall top plate section 13R configuring the wall top plate section 13 are positioned on the same plane. As depicted in FIG. 1E, when the rear outer wall section 12B is opened, the rear wall top plate section 13B (connection end) connected to the rear outer wall section 12B can be moved upward relative to the front wall top plate section 13F, the left wall top plate section 13L, and the right wall top plate section 13R about a crease with the rear wall top plate section 13B. Thus, when the rear outer wall section 12B is opened to the outside, the rear wall top plate section 13B connected to the rear outer wall section 12B is moved upward, so that the rear outer wall section 12B can easily be opened as compared with a case where only the rear outer wall section 12B is moved.

As depicted in FIG. 1A and FIG. 1B, in a state in which the lid section 20 is closed, the lid section 20 has an upper plate section 21 that covers the storage space S1 and the wall top plate section 13 of the storage section 10, an insertion section 22 that is connected to a front end of the upper plate section 21 via a crease, and a side plate section 23 that is connected to a rear end of the upper plate section 21 via a crease. In a state in which the lid section 20 is closed, the upper plate section 21 of the lid section 20 covers the entire storage section 10 in plan view. In addition, the insertion section 22 of the lid section 20 is inserted into the insertion port G when the lid section 20 is closed, so that the lid section 20 is suppressed from being opened without application of an external force.

As depicted in FIG. 1C, the side plate section 23 of the lid section 20 is connected to the bottom plate section 14 via a crease. As depicted in FIG. 3, in a state in which the lid section 20 is closed, the side plate section 23 contacts an outer surface of the rear outer wall section 12B and covers the outer surface of the rear outer wall section 12B. In a state in which the lid section 20 is closed, the side plate section 23 of the lid section 20 covers the outer surface of the rear outer wall section 12B, so that the rear outer wall section 12B can be restricted from being opened to the outside. Thus, it is possible to suppress the accessories stored in the space S2 and the space S3 from falling out to the outside of the rear outer wall section 12B.

In addition, as depicted in FIG. 1B, a circular-arc slit K is formed in the side plate section 23. Both ends of the slit K are connected to a crease with the upper plate section 21, and a cantilever plate section 24 defined by the slit K and the crease can be bent relative to the upper plate section 21 at an angle different from the angle formed by the upper plate section 21 and the side plate section 23. The cantilever plate section 24 may project rearward of the side plate section 23, for example, in a state in which the lid section 20 is closed. When the cantilever plate section 24 of the box 1 is pulled rearward in a state in which the box 1 is stored in an outer box (not illustrated), the box 1 can be pulled out rearward from the outer box.

2. Relation With Developed View

FIG. 4 is a plan view of a flat plate-shaped box material configuring the box 1. The box 1 is formed by folding the box material depicted in FIG. 4 along creases. In FIG. 4 and FIG. 5A to FIG. 5D to be described later, dotted lines indicate creases of mountain folds, and dashed lines indicate creases of valley folds.

As depicted in FIG. 4, the rear wall top plate section 13B is connected to the rear inner wall section 11B and the rear outer wall section 12B via the creases. Similarly, the front wall top plate section 13F is connected to the front inner wall section 11F and the front outer wall section 12F via the creases, the left wall top plate section 13L is connected to the left inner wall section 11L and the left outer wall section 12L via the creases, and the right wall top plate section 13R is connected to the right inner wall section 11R and the right outer wall section 12R via the creases.

In addition, in the developed view depicted in FIG. 4, the rear inner wall section 11B, the front inner wall section 11F, the left inner wall section 11L, and the right inner wall section 11R configuring the inner circumferential wall section 11 are formed at positions apart from each other. Among the wall sections configuring the inner circumferential wall section 11, the rear inner wall section 11B and the front inner wall section 11F are connected to a front end and a rear end of the middle plate section 15 via creases, respectively, but the left inner wall section 11L and the right inner wall section 11R are not connected to the middle plate section 15. With such a configuration, the box 1 can be assembled from a single plate-like box material.

As depicted in FIG. 4, support pieces 34L and 34R are formed at a left end and a right end of the middle plate section 15, respectively. The support pieces 34L and 34R are bent downward relative to the middle plate section 15 and contact the bottom plate section 14 to support the middle plate section 15, and the space S3 (see FIG. 3) is formed between the bottom plate section 14 and the middle plate section 15. A width (the distance between the support piece 34L and the support piece 34R) D3 of the middle plate section 15 in a left-right direction is equal to a width D4 of the bottom plate section 14 in the left-right direction. With such a configuration, a sufficient space in the left-right direction can be secured in the space S3 between the bottom plate section 14 and the middle plate section 15.

As depicted in FIG. 4, first extension sections 31L and 31R are connected to the rear inner wall section 11B via creases. The first extension sections 31L and 31R are connected to a left end and a right end of the rear inner wall section 11B, respectively. Second extension sections 32L and 32R are connected to the front inner wall section 11F via creases. The second extension sections 32L and 32R are connected to a left end and a right end of the front inner wall section 11F, respectively. The first extension sections 31L and 31R have recessed sections C1 on the outer edges, and the second extension sections 32L and 32R have recessed sections C2 on the outer edges. In the example depicted in FIG. 4, the first extension sections 31L and 31R and the second extension sections 32L and 32R are formed in the same shape. The functions of the first extension sections 31L and 31R and the second extension sections 32L and 32R will be described later.

As depicted in FIG. 4, insertion sections 33L and 33R are connected to the left inner wall section 11L and the right inner wall section 11R via creases, respectively. The insertion section 33L is formed on the side opposite to the side where the left wall top plate section 13L is formed in the left inner wall section 11L. The insertion section 33R is formed on the side opposite to the side where the right wall top plate section 13R is formed in the right inner wall section 11R. The functions of the insertion sections 33L and 33R will be described later.

In the developed view depicted in FIG. 4, the rear outer wall section 12B, the front outer wall section 12F, the left outer wall section 12L, and the right outer wall section 12R configuring the outer circumferential wall section 12 are formed at positions apart from each other. Among the wall sections configuring the outer circumferential wall section 12, the front outer wall section 12F, the left outer wall section 12L, and the right outer wall section 12R are connected to the bottom plate section 14 via creases. In the outer circumferential wall section 12, the rear outer wall section 12B is not connected to the left outer wall section 12L, the right outer wall section 12R, and the bottom plate section 14. Therefore, in a state in which the box 1 is assembled and the lid section 20 is opened, the rear outer wall section 12B can be opened and closed to the outside of the storage section 10.

In addition, in the developed view depicted in FIG. 4, the rear wall top plate section 13B, the front wall top plate section 13F, the left wall top plate section 13L, and the right wall top plate section 13R configuring the wall top plate section 13 are formed at positions apart from each other. Since the rear wall top plate section 13B is not connected to the left wall top plate section 13L and the right wall top plate section 13R in the wall top plate section 13, the rear wall top plate section 13B connected to the rear outer wall section 12B can be moved upward relative to the front wall top plate section 13F, the left wall top plate section 13L, and the right wall top plate section 13R when the rear outer wall section 12B is opened as depicted in FIG. 1E.

3. Assembly of Box

FIG. 5A to FIG. 5D are diagrams each explaining a method of assembling the box 1. It should be noted that, in FIG. 5A to FIG. 5D, the illustrations of the slit K and the cantilever plate section 24 depicted in FIG. 4 are omitted. First, as depicted in FIG. 5A, in the flat plate-shaped box material, the front outer wall section 12F is bent relative to the bottom plate section 14, and the front wall top plate section 13F is bent relative to the front outer wall section 12F. Then, the rear outer wall section 12B is bent relative to the rear wall top plate section 13B, the rear inner wall section 11B is bent relative to the rear wall top plate section 13B and the middle plate section 15, and the front inner wall section 11F is bent relative to the front wall top plate section 13F and the middle plate section 15. In this step, the front outer wall section 12F, the front wall top plate section 13F, the front inner wall section 11F, the middle plate section 15, the rear inner wall section 11B, the rear wall top plate section 13B, and the rear outer wall section 12B are arranged rearward in this order. It should be noted that, in FIG. 5A, the left and right wall top plate sections 13L and 13R, the inner wall sections 11L and 11R, and the insertion sections 33L and 33R are also bent, but these may be bent in the subsequent step.

Next, as depicted in FIG. 5A and FIG. 5B, the first extension sections 31L and 31R are bent forward relative to the rear inner wall section 11B, and the second extension sections 32L and 32R are bent rearward relative to the front inner wall section 11F. At this time, the recessed section C2 formed at the edge of the second extension section 32L is hooked to the recessed section C1 formed at the edge of the first extension section 31L on the left side, so that the first extension section 31L and the second extension section 32L are fixed. Similarly to this, the recessed section C2 formed at the edge of the second extension section 32R is hooked to the recessed section C1 formed at the edge of the first extension section 31R on the right side, so that the first extension section 31R and the second extension section 32R are fixed. In addition, the support pieces 34L and 34R are bent downward relative to the middle plate section 15.

FIG. 5C depicts a state in which the box 1 which is being assembled and is depicted in FIG. 5B is viewed from above. As depicted in FIG. 5C, in a state in which the first extension section 31L and the second extension section 32L on the left side are engaged with each other, these extension sections extend in an oblique direction relative to a front-rear direction. In addition, in a state in which the first extension section 31R and the second extension section 32R on the right side are engaged with each other, these extension sections extend in an oblique direction relative to the front-rear direction. Thus, in plan view of the box 1, a hexagon having the first extension sections 31L and 31R, the second extension sections 32L and 32R, the rear inner wall section 11B, and the front inner wall section 11F as sides is formed. Here, a gap (second gap) is formed between the first extension section 31L and the second extension section 32L which are engaged with each other and the middle plate section 15. In addition, a gap (second gap) is also formed between the first extension section 31R and the second extension section 32R which are engaged with each other and the middle plate section 15.

Next, as depicted in FIG. 5B and FIG. 5D, the left portion of the storage section 10 is formed by bending the left outer wall section 12L, the left wall top plate section 13L, the left inner wall section 11L, and the insertion section 33L. By this step, the first extension section 31L and the second extension section 32L on the left side are arranged below the left wall top plate section 13L, and the left inner wall section 11L is arranged on the inner side relative to the first extension section 31L and the second extension section 32L. In addition, in this step, the insertion section 33L is inserted into the gap (second gap) formed between the first extension section 31L and the second extension section 32L on one hand and the middle plate section 15 on the other hand. As described above, since the first extension section 31L and the second extension section 32L extend in the oblique direction relative to the front-rear direction, these extension sections come into contact with an upper surface of the insertion section 33L in a region Tl wider than that of a case where these extension sections extend only in the front-rear direction. Therefore, it is possible to effectively suppress the insertion section 33L from being removed from the gap formed between the first extension section 31L and the second extension section 32L on one hand and the middle plate section 15 on the other hand. Thus, the left inner wall section 11L can be suppressed from being moved to the inside about the crease with the left wall top plate section 13L.

Similarly, the right portion of the storage section 10 is formed by bending the right outer wall section 12R, the right wall top plate section 13R, the right inner wall section 11R, and the insertion section 33R. By this step, the first extension section 31R and the second extension section 32R on the right side are arranged below the right wall top plate section 13R, and the right inner wall section 11R is arranged on the inner side relative to the first extension section 31R and the second extension section 32R. In this step, the insertion section 33R is inserted into the gap formed between the first extension section 31R and the second extension section 32R on one hand and the middle plate section 15 on the other hand. The first extension section 31R and the second extension section 32R come into contact with an upper surface of the insertion section 33R in a region T2 wider than that of a case where these extension sections extend only in the front-rear direction. Thus, the right inner wall section 11R can be suppressed from being moved to the inside about the crease with the right wall top plate section 13R.

Finally, the restriction sections 16L and 16R are bent relative to the rear outer wall section 12B, and the restriction sections 16L and 16R are stored inside the storage section 10 (inside the space S2 depicted in FIG. 3). Then, the side plate section 23, the upper plate section 21, and the insertion section 22 are bent relative to the bottom plate section 14, and the insertion section 22 is inserted into the inside of the insertion port G. By the above steps, the box 1 can be assembled from the box material such as plate-like cardboard or corrugated cardboard.

4. Summary

As described above, the box 1 described in the present embodiment is provided with the storage section 10 in which the storage space S1 for storing articles is defined and the lid section 20 for covering the upper side of the storage section 10. The storage section 10 has the inner circumferential wall section 11 that surrounds the storage space S1, the outer circumferential wall section 12 that surrounds the inner circumferential wall section 11 and forms a gap with the inner circumferential wall section 11, and the wall top plate section 13 that 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 the creases. By forming a gap between the outer circumferential wall section 12 and the inner circumferential wall section 11, a shock caused in the outer circumferential wall section 12 due to the falling of the box 1 or the like can be suppressed from being transmitted to the storage space S1 defined by the inner circumferential wall section 11. Therefore, the articles stored in the storage space S1 can be protected from the shock.

In addition, the outer circumferential wall section 12 of the box 1 has the rear outer wall section 12B that can be opened and closed to the outside about the crease with the wall top plate section. Thus, a space (for example, the space S2) for storing accessories of the articles can be secured between the inner circumferential wall section 11 (rear inner wall section 11B) and the rear outer wall section 12B. In addition, the lid section 20 has the side plate section 23 that covers the outer surface of the rear outer wall section 12B in a state in which the lid section 20 is closed. Thus, in a state in which the lid section 20 is closed, it is possible to restrict the rear outer wall section 12B from being opened to the outside, and it is possible to suppress the accessories stored inside the rear outer wall section 12B from falling out to the outside.

It should be noted that the present invention is not limited to the above-described embodiment. Although the shape of the box 1 described in the embodiment is square in plan view, the shape of the box 1 in plan view may be, for example, a polygon such as a triangle or a pentagon, or may have a circular-arc portion. Also in this case, the articles stored in the storage space S1 can be protected from a shock by providing the inner circumferential wall section 11 that surrounds the storage space S1 and the outer circumferential wall section 12 that surrounds the inner circumferential wall section 11 and forms a gap with the inner circumferential wall section 11. In addition, a part (for example, the rear outer wall section 12B) of the outer circumferential wall section 12 can be opened and closed to the outside, and the side plate section 23 of the lid section 20 covers an outer surface of the part in a state in which the lid section 20 is closed, so that a storage place for accessories of the articles can be secured between the inner circumferential wall section 11 and the outer circumferential wall section 12, and the accessories can be suppressed from falling out to the outside of the outer circumferential wall section 12 in a state in which the lid section 20 is closed.
