JP7467933B2 - Lead acid battery shipping box - Google Patents

Description

The technology disclosed in this specification relates to shipping boxes for lead-acid batteries.

For example, in the case of lead-acid batteries installed in automobiles (see, for example, Patent Document 1), it was conventionally the case that when the installed lead-acid battery approached the end of its life, it was common to purchase a new lead-acid battery at a sales outlet such as an automobile dealer or an automobile parts store and replace it. When delivering lead-acid batteries to a sales outlet, for example, the delivery source packs multiple lead-acid batteries in respective packing boxes (see, for example, Patent Document 2), stacks them on a pallet, and wraps a sheet around them to prevent the load from shifting, and delivers the multiple lead-acid batteries in a bundled state to the sales outlet.

JP 2008-235055 A Patent No. 6307986

In recent years, sales of lead-acid batteries via mail order sales, such as online shopping, have become more common in BtoC (Business to Consumer) sales. As a result, lead-acid batteries are increasingly being delivered in single units. However, until now, the issues involved in delivering lead-acid batteries in single units had not been fully considered.

This specification discloses technology that improves the issues that arise when shipping lead-acid batteries one at a time.

A delivery box for a lead-acid battery, comprising: a delivery box body that houses a packaging box in which a lead-acid battery is packed, the delivery box body having an internal space of the delivery box body with a width in a short side direction of the packaging box in a top view that is wider than the width of the packaging box in the short side direction when the packaging box is housed in the delivery box body; and a first restricting portion that restricts the position of the packaging box in the short side direction inside the delivery box body.

This will improve the issues that arise when shipping lead-acid batteries individually.

(1) A delivery box for a lead-acid battery, comprising: a delivery box body that houses a packaging box in which a lead-acid battery is packed, the delivery box body having an internal space of the delivery box body in a short side direction of the packaging box in a top view that is wider than the width of the packaging box in the short side direction when the packaging box is housed in the delivery box body; and a first restricting portion that restricts the position of the packaging box in the short side direction inside the delivery box body.

As described in the aforementioned Patent Document 1, lead-acid batteries contain electrolyte inside. Typically, lead-acid batteries are formed with a gas vent hole to release gas generated inside, so if the lead-acid battery falls over, electrolyte may leak from the gas vent hole.

The inventors of the present application have discovered that when lead-acid batteries are shipped individually, there is a problem in that the packaging box is more likely to tip over in the direction of its short side during the shipping process than when multiple batteries are shipped together, increasing the possibility of leakage.
The inventors of the present application conducted a private experiment in which a packing box containing a lead-acid battery was shipped in a state in which it was made difficult to tip over in the short side direction by using an auxiliary member. As a result, the incidence of leakage was about 3% when the packing box was shipped as it was, whereas the incidence rate was about 1% when the packing box was shipped in a state in which it was made difficult to tip over in the short side direction, showing a significant improvement. From this result, it became clear that the occurrence of leakage can be suppressed if the packing box is shipped in a state in which it is difficult to tip over in the short side direction.

The above-mentioned shipping box makes it difficult for the shipping box to tip over in the short side direction compared to when the shipping box is shipped as is, because the width of the internal space of the shipping box body in the short side direction of the packing box when viewed from above is wider than the width of the packing box in the short side direction. Therefore, the above-mentioned shipping box can alleviate the issue of shipping lead-acid batteries individually (the issue of the packing box tipping over in the short side direction during shipping, which may cause leakage).

However, if the width of the bottom surface of the delivery box body is widened, a gap will be created between the delivery boxes in the short side direction of the packaging box, and the position of the packaging box will become unstable inside the delivery box during delivery. With the delivery box described above, a first regulating part that regulates the position of the packaging box in the short side direction is provided inside the delivery box, so the position of the packaging box in the short side direction inside the delivery box can also be stabilized.

(2) The delivery box body may have two slits or slots extending from a side wall perpendicular to the short side direction of the packaging box to a bottom wall in a top view, and the first restricting portion may be formed by folding back inward a portion of the delivery box body between the two slits or slots.

With the above delivery box, the first restricting portion is formed integrally with the delivery box body, which reduces the number of parts required for the delivery box compared to when the first restricting portion, which is separate from the delivery box body, is housed inside the delivery box body.

(3) A second restricting portion is provided inside the delivery box body to restrict the position of the long side of the packaging box, and the delivery box body has two slits or slots extending from a side wall perpendicular to the long side of the packaging box in a top view to a bottom wall, and the second restricting portion may be formed by folding back inward the portion of the delivery box body between the two slits or slots.

The above-mentioned delivery box allows the position of the packaging box in the long side direction to be regulated inside the delivery box. Furthermore, with the above-mentioned delivery box, the second regulating portion is formed integrally with the delivery box body, so the number of parts of the delivery box can be reduced compared to when the second regulating portion, which is separate from the delivery box body, is housed inside the delivery box body.

(4) A third regulating portion is provided inside the delivery box body to regulate the position of the packaging box in the long side direction, the delivery box body having two slits or slots extending from the side wall perpendicular to the long side direction of the packaging box to the top wall in a top view, the third regulating portion is formed by folding back the portion of the delivery box body between the two slits or slots inward, and the third regulating portion may regulate the position of the packaging box closer to the center of the delivery box than the second regulating portion in a top view.

Lead-acid batteries may come in multiple sizes, depending on the width of the long side. In such cases, if the second regulating section is set to accommodate a lead-acid battery with a wide long side, the position of the long side of the packaging box will not be adequately regulated by the second regulating section for a lead-acid battery with a narrow long side. However, it is inefficient to prepare a shipping box for each size.

According to the above-mentioned shipping box, the third regulating portion regulates the position of the packaging box closer to the center of the shipping box than the second regulating portion, so in the case of a lead-acid battery that is wider in the long side direction, the position in the long side direction can be regulated by the second regulating portion by not forming the third regulating portion. On the other hand, in the case of a lead-acid battery that is narrower in the long side direction, the position in the long side direction can be regulated by forming the third regulating portion. This eliminates the need to prepare shipping boxes for each size.

(5) The first regulating portion may be a spacer that is housed inside the delivery box body and regulates the position of the packaging box in the short side direction.

In order to more reliably regulate the position of the packaging box, it is desirable to be able to freely set the shape of the first regulating portion to a certain extent. However, if the first regulating portion is integrated with the delivery box body, the degree of freedom in the shape of the first regulating portion is limited.
According to the above-mentioned delivery box, since the first restricting portion is a spacer separate from the delivery box body, the degree of freedom in shape is improved compared to when the first restricting portion is integrated with the delivery box body. Therefore, the shape of the first restricting portion can be made to more reliably restrict the position of the packaging box.

(6) The spacer may include a fourth restricting portion that restricts the position of the packaging box in the long side direction when viewed from above.

With the above shipping box, the position of the long side as well as the short side can be regulated.

(7) The fourth restricting portion is formed in a plate shape extending parallel to and spaced apart from the bottom wall of the delivery box, and a crease or perforation may be formed at the tip portion toward the center of the delivery box when viewed from above.

Lead-acid batteries may come in multiple sizes depending on the width of the long side. For example, if the fourth regulating portion is set to fit a lead-acid battery with a wide long side, the position of the long side of the packaging box will not be sufficiently regulated by the fourth regulating portion in the case of a lead-acid battery with a narrow long side. However, it is inefficient to prepare spacers for each size.

According to the above-mentioned shipping box, a crease or perforation is formed at the tip of the fourth regulating part, so in the case of a lead-acid battery that is wide in the long side direction, the position in the long side direction can be regulated by folding the tip up or down along the crease or perforation (or by cutting along the perforation). On the other hand, in the case of a lead-acid battery that is narrower in the long side direction, the position in the long side direction can be regulated by the fourth regulating part by not folding (or cutting) the tip. This eliminates the need to prepare shipping boxes for each size.

(8) The spacer has a fifth regulating portion that regulates the position of the packaging box in the long side direction when viewed from above, and the fifth regulating portion is formed by raising a part of the bottom wall of the spacer, and may regulate the position of the packaging box closer to the center of the delivery box than the fourth regulating portion when the tip is not bent or when the tip is not cut off when viewed from above.

If there is a lead-acid battery whose width in the long side direction is even narrower than the lead-acid battery described above, even if the tip of the fourth regulating portion is not bent or cut off, the fourth regulating portion will not come close to the lead-acid battery and will not be able to regulate the position of the lead-acid battery in the long side direction.
According to the above-mentioned shipping box, the fifth restriction portion can be formed by raising the bottom wall of the spacer, and in the case of a lead-acid battery having a narrower width in the long side direction, the fifth restriction portion can be formed to restrict the position in the long side direction. Therefore, it is not necessary to prepare shipping boxes for each size.

(9) The spacer may be formed by bending a single piece of cardboard formed into a predetermined shape.

With the above-mentioned shipping box, the spacer can be formed by bending a single piece of cardboard, which reduces the number of parts required compared to when a spacer is formed from multiple components.

(10) The height of the packaging box may be the same as the height of the interior space of the delivery box.

The above phrase "the height of the packaging box and the height of the internal space of the shipping box are the same" is not limited to the case where the height of the packaging box and the height of the internal space of the shipping box are exactly the same, but also includes the case where they are approximately the same.
The delivery boxes containing the packing boxes may be stacked and stored in a warehouse. In that case, if the delivery box does not have vertical strength, the lower delivery box may be crushed. Normally, lead-acid batteries have enough strength to not break when stacked several times. According to the above delivery box, the height of the delivery box is the same as the height of the internal space of the delivery box. In other words, there is almost no gap between the upper surface of the delivery box and the upper wall of the delivery box inside the delivery box. Therefore, the weight of the upper delivery box is supported by the lead-acid battery contained in the lower delivery box. Therefore, even if the delivery boxes are stacked, the delivery boxes can be prevented from being crushed.

(11) The position of the packaging box may be restricted to the center of the short side and long side directions of the packaging box when viewed from above.

The above "center in the short side direction and long side direction" is not limited to being exactly in the center, but includes being approximately in the center.
When stacking delivery boxes containing packaging boxes, if the position of the packaging boxes inside the delivery box is biased to the front, back, left, or right, the delivery boxes are likely to be crushed when stacked. With the above delivery box, the packaging box is located in the center of the delivery box when viewed from above, so the delivery boxes are less likely to be crushed when stacked.

<Embodiment 1>
A first embodiment will be described with reference to Figures 1 to 11. In the following description, the reference numerals of the drawings may be omitted for the same components, with some exceptions.

(1) Lead-acid battery and packaging box As shown in Fig. 1, the lead-acid battery 1 according to the first embodiment is rectangular when viewed from above. As shown in Table 1 below, the lead-acid battery 1 is classified into types B, D, etc. depending on the type of battery terminal (external electrode terminal).

As shown in Table 1, each type of lead-acid battery 1 is available in a number of sizes. For example, type B lead-acid batteries 1 are available in four sizes for general vehicles: B17, B19, B20, and B24. All four sizes have the same height and the same width in the short side direction when viewed from above, but the width in the long side direction when viewed from above is different. Specifically, the width in the long side direction of B17 is approximately 17 cm, B19 is approximately 19 cm, B20 is approximately 20 cm, and B24 is approximately 24 cm.
The size of the lead-acid battery 1 is expressed differently for general vehicles and for vehicles with an idling stop function. For vehicles with an idling stop function, the size of the B-type lead-acid battery 1 is expressed as J, K, M, and N. B17=J, B19=K, B20=M, and B24=N.

The D-type lead-acid battery 1 comes in four sizes: D20, D23, D26, and D31. All four sizes have the same height and the same width in the short side direction when viewed from above, but different widths in the long side direction when viewed from above.
In the following description, three sizes of lead-acid batteries B19, B20, and B24 will be described as examples of the lead-acid batteries 1 that are mainly sold on the market.

As shown in FIG. 2, lead-acid batteries 1 are packed and sold in packaging boxes 2. The size of the packaging box 2 varies depending on the size of the lead-acid batteries 1 packed in the packaging box 2. In the following explanation, the packaging box 2 in which a B24 size lead-acid battery 1 is packed is referred to as packaging box 2A, the packaging box 2 in which a B20 size lead-acid battery 1 is packed is referred to as packaging box 2B, and the packaging box 2 in which a B19 size lead-acid battery 1 is packed is referred to as packaging box 2C, and when no distinction is made between these, they will simply be referred to as packaging box 2.

When viewed from above, the width in the short side direction and the width in the long side direction of the internal space of the packaging box 2 are approximately the same as the width in the short side direction and the width in the long side direction of the lead-acid battery 1 packed in the packaging box 2. The height of the internal space of the packaging box 2 is approximately the same as the height of the lead-acid battery 1 packed in the packaging box 2. In the following description, the short side direction of the packaging box 2 refers to the short side direction of the packaging box 2 when viewed from above, and the long side direction of the packaging box 2 refers to the long side direction of the packaging box 2 when viewed from above.

(2) Configuration of the Delivery Box With reference to Fig. 3 to Fig. 6, a cardboard delivery box 3 used when delivering lead-acid batteries 1 one by one by a home delivery service or the like will be described. The delivery box 3 is used in common for a plurality of sizes of lead-acid batteries 1 of the same type. In the following description, an example will be described in which the delivery box 3 is used in common for three sizes, B19, B20, and B24.
3 to 5, the delivery box 3 is formed in a rectangular parallelepiped shape and is rectangular when viewed from above. In the following description, the short side direction of the delivery box 3 refers to the short side direction of the delivery box 3 when viewed from above, and the long side direction of the delivery box 3 refers to the long side direction of the delivery box 3 when viewed from above.

As shown in FIG. 3, the delivery box 3 has a delivery box body 10, a first restricting portion 11, a second restricting portion 12, and a third restricting portion 13. The first restricting portion 11, the second restricting portion 12, and the third restricting portion 13 are integrally formed with the delivery box body 10.

The packaging box 2 is placed in the delivery box 3 with its short side aligned with the short side of the delivery box 3 and its long side aligned with the long side of the delivery box 3. The delivery box 3 is sized so that when the packaging box 2A in which the B24 size lead-acid battery 1 is packed is positioned in the center of the delivery box 3 in a top view, a gap of D2 [millimeters] is created on both sides of the long side of the packaging box 2A and a gap of D1 [millimeters] is created on both sides of the short side. The height of the internal space of the delivery box 3 is approximately the same as the height of the packaging box 2.

That is, the size of the internal space of the delivery box 3 is as follows.
Width in the short side direction: Width in the short side direction of the packaging box 2 + 2 x D1
Width in the long side direction: Width in the long side direction of the packaging box 2A + 2 × D2
Height: Height of the packaging box 2 The above-mentioned D1 can be determined as appropriate, but it is desirable that it be a value that makes it difficult for the delivery box 3 to tip over in the short side direction. The value that makes it difficult for the delivery box 3 to tip over in the short side direction can be determined as appropriate through experimentation. The same applies to D2. When the inventors of the present application conducted experiments, it was found that in Type B, it is desirable that D1 be 33% or more of the width of the short side direction of the packaging box 2, and D2 be 11% or more of the width of the long side direction of the packaging box 2A.

As shown in Figure 6, the shipping box 3 is formed by folding a single piece of cardboard 14 formed into a predetermined shape. The cardboard board 14 has two long side walls 15 (an example of a side wall perpendicular to the short side direction of the packing box), two short side walls 16 (an example of a side wall perpendicular to the long side direction of the packing box) that are shorter in width than the long side walls 15, upper flaps 17 (an example of an upper wall) connected to the upper side of each long side wall 15, lower flaps 18 (an example of a bottom wall) connected to the lower side of each long side wall 15, upper flaps 19 (an example of an upper wall) connected to the upper side of each short side wall 16, lower flaps 20 (an example of a bottom wall) connected to the lower side of each short side wall 16, two long holes 21 extending parallel to each other from the long side walls 15 to the lower flaps 18, two long holes 22 extending parallel to each other from the short side walls 16 to the lower flaps 20, and two third notches 23 extending parallel to each other from the short side walls 16 to the upper flaps 19. To make assembly easier, the cardboard sheet 14 is pre-scored where it will be folded.

The upper flap 17 that is continuous with the long side wall 15 has a symmetrical shape, with the width of the upper side being narrower than the width of the lower side. Specifically, the left side of the upper flap 17 extends upward from the boundary with the long side wall 15, then inclines diagonally upward to the right, and then extends upward again. The same is true for the right side.
The lower flap 18 that is connected to the bottom of the long side wall 15 is also symmetrical in shape, with the width of the lower side being narrower than the width of the upper side. Specifically, the left side of the lower flap 18 extends downward from the boundary with the long side wall 15, then inclines diagonally downward to the right, and then extends downward again. The same is true for the right side.

The upper flap 19 that is connected to the short side wall 16 also has a symmetrical shape, with the width of the upper side being narrower than the width of the lower side. Specifically, the left side of the upper flap 19 extends upward from the boundary with the short side wall 16, and then slopes diagonally upward to the right before reaching the upper side. The same is true for the right side.
The lower flap 20 that is connected to the bottom of the short side wall 16 is also symmetrical in shape, with the width of the lower side being narrower than the width of the upper side. Specifically, the left side of the lower flap 20 extends downward from the boundary with the short side wall 16, then inclines diagonally downward to the right, and then extends downward again. The same is true for the right side.

The two first long holes 21 extend D1+D4 upward and D1 downward from the boundary between the long side wall 15 and the lower flap 18. The left-right midpoint of the two first long holes 21 coincides with the left-right center of the long side wall 15. In the following description, the portion between the two first long holes 21 is referred to as the first folded portion 24. The first folded portion 24 is formed with a fold 24A connecting the upper end of one first long hole 21 to the upper end of the other first long hole 21, a fold 24B extending in the left-right direction at a position D1 below the upper end of the first long hole 21, and a fold 24C connecting the lower end of one first long hole 21 to the lower end of the other first long hole 21.

The two second long holes 22 extend D2+D5 upward and D2 downward from the boundary between the short side wall 16 and the lower flap 20. The left-right midpoint of the two second long holes 22 coincides with the left-right center of the short side wall 16. In the following description, the portion between the two second long holes 22 is referred to as the second folded portion 25. The second folded portion 25 is formed with a fold 25A connecting the upper end of one second long hole 22 to the upper end of the other second long hole 22, a fold 25B extending left-right at a position D2 below the upper end of the second long hole 22, and a fold 25C connecting the lower end of one second long hole 22 to the lower end of the other second long hole 22.

The two third slits 23 extend upward by D3 (>D2) and downward by D3 from the boundary between the short side wall 16 and the upper flap 19. The left-right midpoint of the two third slits 23 coincides with the left-right center of the short side wall 16. In the following description, the portion between the two third slits 23 is referred to as the third folded portion 27. The third folded portion 27 has a crease 27A connecting the upper end of one third slit 23 to the upper end of the other third slit 23, a crease 27B formed along the boundary between the short side wall 16 and the upper flap 19, and a crease 27C connecting the lower end of one third slit 23 to the lower end of the other third slit 23.

(3) Putting the Packaging Box into the Delivery Box The state in which the packaging box 2 is put into the delivery box 3 will be described for each size.

7, when a packaging box 2A in which a B24 size lead-acid battery 1 is packed is placed in a delivery box 3, the first fold-back portion 24 is folded inward to form the first restricting portion 11, and the second fold-back portion 25 is folded inward to form the second restricting portion 12. In contrast, the third fold-back portion 27 is not folded back. That is, the third restricting portion 13 is not formed.

8, the width of the first restricting portions 11 when viewed from the long side direction of the shipping box 3 is D1. The distance between the two first restricting portions 11 is approximately the same as the width of the short side direction of the packaging box 2. Therefore, when the packaging box 2A is placed in the shipping box 3, both side surfaces of the packaging box 2A in the short side direction are close to the first restricting portions 11.
As shown in Fig. 9, the width of the second restricting portion 12 when viewed from the short side direction of the delivery box 3 is D2. The distance between the two formed second restricting portions 12 is approximately the same as the width of the packaging box 2A in the long side direction. Therefore, when the packaging box 2A is placed in the delivery box 3, both side surfaces in the long side direction of the packaging box 2A are close to the second restricting portions 12. As a result, the front-rear, left-right position (position in the short side direction and long side direction) of the packaging box 2A is roughly restricted by the first restricting portion 11 and the second restricting portion 12 while the packaging box 2A is positioned approximately in the center in the front-rear, left-right direction within the delivery box 3.

(3-2) B20 Size As shown in Fig. 3, when a packaging box 2B in which a B20 size lead-acid battery 1 is packed is accommodated in a delivery box 3, a first restricting portion 11 is formed and a third fold-back portion 27 is folded back to form a third restricting portion 13. Although a second restricting portion 12 is also formed in Fig. 3, the second restricting portion 12 does not contribute to restricting the position of the B20 size packaging box 2B and therefore does not have to be formed.

As shown in FIG. 8, the length of the short side of the B20 size and the B24 size are the same, so when the packaging box 2B is placed in the delivery box 3, both side surfaces of the packaging box 2B in the short side direction are close to the first restricting portion 11.

As shown in FIG. 10, the width of the third regulating portion 13 when viewed from the short side direction of the delivery box 3 is D3. Since D3>D2, the third regulating portion 13 extends further toward the center of the delivery box 3 than the second regulating portion 12 when viewed from above. The distance between the two third regulating portions 13 is approximately the same as the width of the long side direction of the packaging box 2B. Therefore, when the packaging box 2B is placed in the delivery box 3, both side surfaces in the long side direction of the packaging box 2B are close to the third regulating portion 13. As a result, the front-rear, front-rear, left-right position of the packaging box 2B is roughly regulated by the first regulating portion 11 and the third regulating portion 13 while the packaging box 2B is positioned approximately in the center in the front-rear, front-rear, left-right direction within the delivery box 3.

(3-3) B19 Size As shown in Fig. 3, the first restricting portion 11 and the third restricting portion 13 are also formed when a packaging box 2C in which a B19 size lead-acid battery 1 is packed is housed in a delivery box 3. Although the second restricting portion 12 is also formed in Fig. 3, the second restricting portion 12 does not contribute to restricting the position of the B19 size packaging box 2C and therefore does not have to be formed.

As shown in FIG. 8, the length of the short side of the B19 size and the B24 size are the same, so when the packaging box 2C is placed in the delivery box 3, both side surfaces of the packaging box 2C in the short side direction are close to the first restricting portion 11.

As shown in FIG. 11, the B19 size is narrower in the long side direction than the B20 size, so when the packaging box 2C is placed in the center of the left-right direction of the delivery box 3, the side surfaces on both sides of the long side direction of the packaging box 2C are not close to either the second restricting portion 12 or the third restricting portion 13. However, the difference in the width of the long side direction between the B19 size and the B20 size is 1 cm. Therefore, the gap between the side surface in the long side direction of the packaging box 2C and the third restricting portion 13 is 5 mm, which can be said to be relatively small. Therefore, although the positional restriction in the long side direction is looser than the B20 size and the B24 size, the position of the packaging box 2C in the front-rear, front-rear, left-right direction is generally restricted by the first restricting portion 11 and the third restricting portion 13 when the packaging box 2C is positioned approximately in the center of the front-rear, front-rear, left-right direction within the delivery box 3.

(4) Indication of precautions during delivery As shown in Figures 3 and 6, precautions are inscribed on the exterior of the delivery box 3 to call attention not to tip the delivery box 3 during delivery. Specifically, the precaution "Do not tip" is printed in conspicuous letters such as red on five of the exterior faces of the delivery box 3 excluding the bottom face. A precaution indicating that it is the top face is printed in conspicuous letters on the top face of the delivery box 3.
The above-mentioned precautions may be indicated by a method other than printing. For example, the precautions may be indicated by attaching a sticker on which the precautions are printed to the outer surface of the delivery box 3.

(5) Delivery of lead-acid batteries using a delivery box In the first embodiment, the lead-acid batteries 1 are stored in a warehouse of a delivery company while being packed in a packaging box 2. When a purchaser orders the lead-acid battery 1 through mail order, a delivery box 3 is assembled by an operator of the delivery company, and the stored packaging box 2 (the packaging box 2 in which the lead-acid battery 1 is packed) is placed in the delivery box 3 (step 1).

Next, the delivery company delivers the delivery box 3 containing the packaging box 2 to the address specified by the purchaser (step 2). Specifically, the delivery box 3 is delivered to the delivery company's sorting center, where it is sorted by workers, and then delivered to the address specified by the purchaser.

(6) Effect of the embodiment According to the shipping box 3, the width of the internal space of the shipping box main body 10 in the short side direction of the packing box 2 in a top view is made wider than the width of the short side direction of the packing box 2, so the shipping box 3 is less likely to tip over in the short side direction compared to when the packing box 2 is shipped as is. Therefore, the shipping box 3 can improve the problem when shipping lead-acid batteries 1 one by one (the problem that the packing box 2 may tip over in the short side direction during the shipping process, causing leakage).
Furthermore, according to the shipping box 3, a first regulating portion 11 that regulates the position of the packing box 2 in the short side direction is provided inside the shipping box 3, so that the position of the packing box 2 in the short side direction inside the shipping box 3 can also be stabilized.

According to the delivery box 3, the first restricting portion 11 is formed integrally with the delivery box body 10, so the number of parts of the delivery box 3 can be reduced compared to when the first restricting portion 11, which is separate from the delivery box body 10, is housed inside the delivery box body 10.

The delivery box 3 is provided with a second restricting portion 12, so that the position of the packaging box 2 in the long side direction can be restricted inside the delivery box 3. Furthermore, the delivery box 3 has a second restricting portion 12 formed integrally with the delivery box body 10, so that the number of parts of the delivery box 3 can be reduced compared to when the second restricting portion 12, which is separate from the delivery box body 10, is housed inside the delivery box body 10.

According to the delivery box 3, the third restricting portion 13 restricts the position of the packaging box 2 closer to the center of the delivery box 3 than the second restricting portion 12 when viewed from above, so in the case of a B20 size packaging box 2B or a B19 size packaging box 2C, which have a narrower width in the long side direction than the B24 size, the third restricting portion 13 can be formed to restrict the position in the long side direction. This means that there is no need to prepare a delivery box 3 for each size.

According to the delivery box 3, the height of the packaging box 2 and the height of the internal space of the delivery box 3 are the same, so there is almost no gap between the top surface of the packaging box 2 and the top wall of the delivery box 3 inside the delivery box 3. Therefore, when multiple delivery boxes 3 are stacked, the weight of the upper delivery box 3 is supported by the lead-acid battery 1 housed in the lower delivery box 3. Therefore, even when the delivery boxes 3 are stacked, the collapse of the delivery boxes 3 can be suppressed.

When using a delivery box 3, the packaging box 2 is located in the center of the delivery box 3 when viewed from above, making it less likely to be crushed when the delivery boxes 3 are stacked.

When a consumer purchases a lead-acid battery 1 through mail order, the consumer may also purchase other products, such as a battery checker. When the shipping box 3 is used, gaps D1 and D2 are created inside the packaging box 2 when the packaging box 2 is housed therein, so there is also the advantage that the purchased other products can be packed together in the shipping box 3.

<Embodiment 2>
The second embodiment will be described with reference to FIGS.

(1) Configuration of the Delivery Box As shown in Fig. 12, the delivery box 203 according to the second embodiment is composed of a delivery box main body 210 and two spacers 40 (an example of a first restricting portion) housed inside the delivery box main body 210. The size of the internal space of the delivery box 203 is the same as the size of the internal space of the delivery box 3 according to the first embodiment, and a gap of D2 is created on both sides in the long side direction of the packaging box 2A, and a gap of D1 is created on both sides in the short side direction of the packaging box 2A.
As shown in FIG. 13 , the front-rear and left-right positions (short side and long side positions) of the packaging box 2 are regulated by two spacers 40 inside the delivery box body 210 .

(1-1) Delivery Box Body As shown in Figure 14, the delivery box body 210 is formed from a single corrugated board 214 formed into a predetermined shape. The corrugated board 214 has two long side walls 215, two short side walls 216 that are shorter in width than the long side walls 215, upper flaps 217 connected to the upper side of each long side wall 215, lower flaps 218 connected to the lower side of each long side wall 215, upper flaps 219 connected to the upper side of each short side wall 216, and lower flaps 220 connected to the lower side of each short side wall 216. Each flap is rectangular in shape.

A first handle portion 41 is formed on the short side wall 216. The first handle portion 41 is cut out in a racetrack shape (a shape consisting of two parallel lines and two semicircles) extending in the left-right direction with the upper side as the base end. When a worker holds the delivery box 203, the first handle portion 41 is bent inward by the worker to form a first handle hole 41A (see FIG. 12).
To facilitate assembly, the cardboard sheet 214 is pre-scored at the fold locations.

15, the spacer 40 is formed by bending a single corrugated cardboard sheet 42. The width of the corrugated cardboard sheet 42 in the front-rear direction is approximately the same as the width of the short side of the internal space of the delivery box 203 when viewed from above.

The cardboard plate 42 is symmetrical from front to back, and from the left side, has a first protrusion 43, two first rectangular holes 44 spaced apart from each other, a second handle hole 45, a first insertion hole 46, an insertion hole 47, two second insertion holes 48 provided in front of and behind the insertion hole 47, a second rectangular hole 49, a recess 50 recessed to the left from the right end of the cardboard plate 42, two second protrusions 51 protruding to the right from the right end of the cardboard plate 42 on both the front and rear of the recess 50, multiple slits 52-57 and 59, multiple folds 61-68, and multiple perforations 58, 69, 70.

The front-to-rear centers of the first protrusion 43, the second handle hole 45, the first insertion hole 46, the insertion hole 47, the second rectangular hole 49 and the recess 50 coincide with the front-to-rear center of the cardboard board 42.
The first protrusion 43 protrudes leftward from the left end of the cardboard plate 42. The first protrusion 43 is formed in a trapezoid shape with the upper base on the right side and the lower base on the left side. The upper base (the right side of the first protrusion 43) is located to the right of the left side of the cardboard plate 42 by approximately the thickness of the cardboard plate 42.

The distance between the rear side 44A of the rear first rectangular hole 44 and the front side 44D of the front first rectangular hole 44 is approximately equal to the width of the packaging box 2 in the short side direction.
The shape of the second hand hole 45 generally corresponds to the shape of the first hand portion 41 formed in the delivery box main body 210. As shown in Fig. 16, the second hand hole 45 is formed at a position overlapping with the first hand hole 41A when viewed from a direction perpendicular to the wall surface of the delivery box main body 210 on which the first hand portion 41 is formed when the spacer 40 is housed in the delivery box main body 210.

The first insertion hole 46 shown in FIG. 15 is a rectangular hole into which the third protrusion 56 and the fourth protrusion 60 described below are inserted. The front-to-rear width of the first insertion hole 46 is approximately the same as the front-to-rear width of the third protrusion 56 and the front-to-rear width of the fourth protrusion 60. The left-to-right width of the first insertion hole 46 is approximately twice the thickness of the cardboard plate 42.

The insertion hole 47 is a hole into which the first protrusion 43 is inserted. The insertion hole 47 is formed across the sixth fold 66. Specifically, the position of the right side of the insertion hole 47 is located to the right of the sixth fold 66 by approximately the thickness of the cardboard board 42. The width of the insertion hole 47 in the front-to-rear direction is wider than the width of the upper base (right side) of the first protrusion 43 and narrower than the width of the lower base (left side).

The two second insertion holes 48 are provided on the front and rear sides of the insertion hole 47. The two second insertion holes 48 are holes into which the second protrusions 51 are inserted. The left side of the second insertion holes 48 overlaps with the sixth fold 66.
The second rectangular hole 49 is formed by connecting a small rectangular hole 49A on the left side to a large rectangular hole 49B on the right side. The width of the small rectangular hole 49A in the front-rear direction is approximately equal to the distance between the two first slits 53. The width of the large rectangular hole 49B in the front-rear direction is approximately equal to the width of the short side of the packaging box 2.

The recess 50 is for allowing the first protrusion 43 inserted into the first insertion hole 46 to escape into the space inside the spacer 40. The recess 50 is recessed from the right end of the cardboard plate 42 to the left. The width of the recess 50 in the front-to-rear direction is the same as or wider than the width of the bottom base of the first protrusion 43.
The two second protrusions 51 are each inserted into the second insertion hole 48. The front-rear position and front-rear width of the second protrusions 51 are approximately the same as the front-rear position and front-rear width of the second insertion hole 48. The left-right width of the second protrusions 51 is approximately the same as the depth of the second insertion hole 48 (the thickness of the cardboard plate 42).

Next, the plurality of slits 52 to 57 and 59 will be described.
Of the two first slits 52, the rear first slit 52 is formed along a trapezoid from the rear end of the upper base (right side) of the first protrusion 43 to the left end of the corrugated board 42. Similarly, the front first slit 52 is formed along a trapezoid from the front end of the upper base (right side) of the first protrusion 43 to the left end of the corrugated board 42.

Of the two second slits 53, the rear second slit 53 extends to the left along the front edge 44B of the rear first rectangular hole 44. The front second slit 53 extends to the left along the rear edge 44C of the front first rectangular hole 44.
Of the two third slits 54, the rear second slit 54 extends to the right along the rear side 44A of the rear first rectangular hole 44. The front third slit 54 extends to the right along the front side 44D of the front first rectangular hole 44. The right end of the third slit 54 extends to the vicinity of the first insertion hole 46.

The fourth slit 55 extends forward from a position a predetermined distance to the left from the right end of the third slit 54 on the rear side, extends to the right at a predetermined position by the thickness of the cardboard plate 42, then extends forward again, then extends to the left at a predetermined position, then extends forward again. By forming the fourth slit 55 in this shape, a third protrusion 56 is formed in the cardboard plate 42. The front-to-rear width of the third protrusion 56 is approximately the same as the front-to-rear width of the first insertion hole 46.

Of the two fifth slits 57, the rear fifth slit 57 extends leftward from the rear edge of the large rectangular hole 49B by approximately the thickness of the cardboard plate 42. The front fifth slit 57 extends in the same manner.
The sixth notch 59 is for forming a fourth protrusion 60. The shape of the fourth protrusion 60 is the same as the shape of the third protrusion 56. When the cardboard plate 42 is folded, the fourth protrusion 60 is inserted into the first insertion hole 46.

Next, a description will be given of the plurality of folds 61 to 68 and 71. The plurality of folds are provided to facilitate assembly of the corrugated cardboard sheet 42.
The first fold 61 coincides with the upper base (right side) of the first protrusion 43 .
The second fold 62 extends from the left end of the rear second slit 53 toward the front to the left end of the front second slit 53 .

Of the two third folds 63, the rear third fold 63 extends rearward from the left rear corner of the rear first rectangular hole 44. The front third fold 63 extends frontward from the left front corner of the front first rectangular hole 44.
The rear fourth fold 64 extends rearward at a position spaced a predetermined distance to the left from the right end of the rear second slit 54. The front fourth fold 64 extends forward at a position spaced a predetermined distance to the left from the right end of the front second slit 54.

The rear fifth fold 65 extends rearward from the right end of the rear second slit 54. The front fifth fold 65 extends frontward from the right end of the front second slit 54.
The sixth fold 66 extends forward and backward from the right end of the cardboard sheet 42 at a position spaced a predetermined distance to the left.

Of the two seventh folds 67, the rear seventh fold 67 extends rearward from the left end of the rear fifth slit 57. The front seventh fold 67 extends frontward from the left end of the front fifth slit 57.
Of the two eighth folds 68, the rear eighth fold 68 extends rearward at a position spaced a predetermined distance to the right from the left end of the rear side of the large rectangular hole 49B. The front eighth fold 68 extends forward at a position spaced a predetermined distance to the right from the left end of the front side of the large rectangular hole 49B.
The ninth fold 71 extends from the right front corner of the rear first rectangular hole 44 toward the front to the right rear corner of the front first rectangular hole 44 .

Next, we will explain the multiple perforations 58, 69, and 70. These perforations are for folding or cutting off parts of the cardboard 42 depending on the size of the packaging box 2.

Of the two first perforations 58, the rear first perforation 58 extends to the right from the rear edge of the large rectangular hole 49B. The same is true for the front first perforation 58. The first perforation 58 is for cutting off a part of the cardboard sheet 42.
The second perforation 69 is formed so as to connect the right ends of the two first perforations 58. The second perforation 69 is for folding the corrugated cardboard 42. Instead of the second perforation 69, a crease may be formed.
Of the two third perforations 70, the rear third perforation 70 extends rearward from the rear end of the sixth slit 59. The front third perforation 70 extends forward from the front end of the sixth slit 59. The third perforations 70 are for folding the cardboard sheet 42. A crease may be formed instead of the third perforations 70.

(1-3) Formation of Spacers and Shape of Spacers With reference to FIG. 15 and FIG. 17, a procedure for forming the spacers 40 from the corrugated cardboard plate 42 will be described.

First, the cardboard sheet 42 shown in FIG. 15 is folded 90 degrees (90 degrees toward the front in the direction perpendicular to the paper surface in FIG. 15, the same applies below) at the seventh crease 67, the eighth crease 68, and the third perforation 70, and the two second protrusions 51 are inserted into the second insertion holes 48.

Next, the left side of the cardboard plate 42 is folded 90 degrees at the sixth fold 66. When the left side of the cardboard plate 42 is folded 90 degrees at the sixth fold 66, the fourth protrusion 60 is inserted into the first insertion hole 46. Next, the cardboard plate 42 is folded 90 degrees at the fifth fold 65, the fourth fold 64, and the third fold 63. Next, the first protrusion 43 is folded 90 degrees or more and inserted into the insertion hole 47 from below.

As shown in FIG. 17, the spacer 40 thus formed has a shape including a bottom wall 80, two guide portions 81, a vertical wall 82, and a plate-like fourth restricting portion 83 that is spaced upward from the bottom wall 80 and extends parallel to the bottom wall 80. The two guide portions 81 are each rectangular annular when viewed from the front-to-rear direction, and are spaced apart from each other in the front-to-rear direction. The vertical wall 82 rises in a plate-like shape from the edge of the bottom wall 80 with its wall surface perpendicular to the left-to-right direction. In appearance, the fourth restricting portion 83 extends horizontally to the left from the vertical wall 82. Although omitted in FIG. 17, the fourth restricting portion 83 has the second perforation 69 described above.

(2) Putting the Packaging Box in the Delivery Box The state in which the packaging box 2 is put in the delivery box 203 will be described for each size.

18 , when a packaging box 2A in which a B24 size lead-acid battery 1 is packed is placed in a delivery box 203, the tip of the fourth restricting portion 83 is cut off at the two first perforations 58 and folded down (or up) at the second perforations 69. The tip of the fourth restricting portion 83 may be cut off at the second perforations 69.
19 , when the packaging box 2A is housed in the delivery box 203, the bottom walls 80 of the two spacers 40 are partially overlapped inside the delivery box 203. When the packaging box 2A is housed in the delivery box 203 in this state, the packaging box 2 is placed on the bottom walls 80 of the two spacers 40.

The distance between the two guide portions 81 in the front-to-back direction matches the distance between the short sides of the packing box 2, so when the packing box 2 is stored, the left side of the packing box 2 is sandwiched in the front-to-back direction (short side direction of the packing box 2) between the two guide portions 81 of the left spacer 40, and the right side of the packing box 2 is sandwiched in the front-to-back direction between the two guide portions 81 of the right spacer 40. This regulates the position of the packing box 2 in the short side direction.

The distance between the second perforation 69 of the fourth regulating portion 83 of one spacer 40 and the second perforation 69 of the fourth regulating portion 83 of the other spacer 40 matches the width of the long side of the packaging box 2A. Therefore, when the packaging box 2A is stored, the packaging box 2A is sandwiched between the two fourth regulating portions 83 in the long side direction. As a result, the position of the packaging box 2A (short side and long side positions) is roughly regulated by the two spacers 40 while it is positioned approximately in the center of the front, back, left and right in the delivery box 203.

(2-2) B20 Size As shown in FIG. 17 described above, when a packaging box 2B in which a B20 size lead-acid battery 1 is packed is placed in a shipping box 203, the fourth restricting portion 83 is not bent at the second perforation 69.
Since the B20 size and the B24 size have the same length in the short side direction, even when the packing box 2B is stored in the delivery box 203, the packing box 2B is sandwiched from the front and rear directions by the two guide parts 81 of each spacer 40. This regulates the position of the packing box 2B in the short side direction.

As shown in FIG. 20, if the fourth restricting portion 83 is not folded at the second perforation 69, when the packaging box 2B is placed in the delivery box 203, the left side of the packaging box 2B is close to the right end of the fourth restricting portion 83 of the left spacer 40. The same is true for the right side of the packaging box 2. As a result, the front-to-back and left-to-right position of the packaging box 2B is roughly restricted by the spacer 40 while it is positioned approximately in the center in the front-to-back and left-to-right directions within the delivery box 203.

(2-3) B19 Size As shown in Fig. 21, when a packaging box 2C in which a B19 size lead-acid battery 1 is packed is placed in a shipping box 203, the fourth restricting portion 83 is not folded at the second perforation 69, as in the case of packaging box 2B. In the case of packaging box 2C, a part of the bottom wall 80 of the spacer 40 is raised to form a fifth restricting portion 90. The fifth restricting portion 90 is located closer to the center of the shipping box 203 than the fourth restricting portion 83 in an unfolded state, as viewed from above.

Since the B19 size and the B20 size have the same length in the short side direction, when the packaging box 2C is placed in the delivery box 203, the packaging box 2C is sandwiched from the front and rear between the two guide portions 81 of the left and right spacers 40.
22, when the fifth restricting portion 90 is formed, when the packaging box 2C is placed in the delivery box 203, the left side surface of the packaging box 2C comes close to the fifth restricting portion 90 of the left spacer 40. The same is true for the right side of the packaging box 2C. As a result, the position of the packaging box 2C in the front, back, left and right directions is generally restricted by the spacer 40 while the packaging box 2C is positioned approximately in the center in the front, back, left and right directions within the delivery box 203.

(3) Indication of Precautions During Delivery As shown in Figures 12 and 14, precautions are also inscribed on the outside of the delivery box 203 to warn users not to tip the delivery box 203 during delivery.

(4) Effect of the embodiment According to the delivery box 203, the first restricting portion is the spacer 40 separate from the delivery box main body 10, so the degree of freedom in shape is improved compared to when the first restricting portion is integrated with the delivery box main body 10. Therefore, the shape of the first restricting portion can be made to more reliably restrict the position of the packaging box 2.

According to the delivery box 203, the spacer 40 is provided with a fourth restricting portion 83 that restricts the position of the long side of the packaging box 2 when viewed from above, so that the position of the long side can be restricted in addition to the position of the short side.

According to the delivery box 203, the second perforation 69 is formed at the tip of the fourth restricting portion 83, so in the case of the packaging box 2A, the position in the long side direction can be restricted by bending the tip up or down. On the other hand, in the case of the packaging box 2B, the position in the long side direction can be restricted by not bending the tip. Therefore, it is not necessary to prepare delivery boxes 203 for each size.

According to the delivery box 203, the fifth restricting portion 90 can be formed by raising the bottom wall 80 of the spacer 40. In the case of the packaging box 2C, the fifth restricting portion 90 can be formed to restrict the position in the long side direction. This means that there is no need to prepare delivery boxes 203 for each size.

With the delivery box 203, the spacer 40 can be formed by bending a single piece of cardboard 214, which reduces the number of parts compared to forming the spacer 40 from multiple components.

<Other embodiments>
The present invention is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included within the technical scope of the present invention.

(1) In the above embodiment 1, a gap D2 is generated in the long side direction when the packaging box 2 is contained in the delivery box 3, but it is also possible to prevent a gap from being generated in the long side direction.

(2) In the above embodiment 1, the cardboard plate 14 has two oblong holes 21, two oblong holes 22, and two third notches 23. However, the oblong holes 21 and the oblong holes 22 may be notches. The notches 23 may be oblong holes.

(3) In the above embodiment 1, the delivery box 3 is used commonly for the three sizes of lead-acid batteries 1, but the delivery box 3 may be prepared for each size of lead-acid batteries 1. In that case, unnecessary regulating parts may not be formed. For example, in the case of a delivery box 3 dedicated to a B24 size packaging box 2A, the third regulating part 13 is not used and is therefore unnecessary. Therefore, the third regulating part 13 may not be formed. In the case of a delivery box 3 dedicated to a B20 size packaging box 2B or a delivery box 3 dedicated to a B19 size packaging box 2C, the second regulating part 12 does not contribute to regulating the position of the packaging box 2B or the packaging box 2C and is therefore unnecessary. Therefore, the second regulating part 12 may not be formed.

(4) In the above embodiment 2, a gap D2 is generated in the long side direction when the packaging box 2 is contained in the delivery box 203. However, it is also possible to prevent a gap from being generated in the long side direction.

(5) In the above embodiment 2, the second perforation 69 is formed in the fourth restricting portion 83 of the spacer 40. However, if a B24 size packaging box 2A is not accommodated, the second perforation 69 does not need to be formed.

(6) In the above embodiment 2, the fifth restricting portion 90 is formed by raising the bottom wall 80 of the spacer 40. However, if a B19 size packaging box 2C is not accommodated, the fifth restricting portion 90 does not have to be formed.

(7) In the above embodiments 1 and 2, the height of the packaging box 2 and the height of the internal space of the delivery box 3 are the same, but they do not necessarily have to be the same.

(8) In the above embodiments 1 and 2, the position of the packaging box 2 is restricted to the center of the short side and long side directions of the packaging box 2 when viewed from above. However, the packaging box 2 does not necessarily have to be restricted to the center.

(9) In the above embodiments 1 and 2, the caution "Do not lay flat" is written on all outer surfaces of the delivery box 3 and delivery box 203 except for the bottom surface. However, the caution does not necessarily have to be written on all outer surfaces except for the bottom surface. However, it is preferable to write the caution on at least two of the five surfaces excluding the bottom surface.

(10) In the above embodiments 1 and 2, the delivery box 3 and the delivery box 203 are described as being applied to three sizes of B-type lead-acid batteries 1, but the dimensions of the delivery box 3 and the delivery box 203 may be changed to apply them to other types and sizes of lead-acid batteries 1. In the above embodiments 1 and 2, the delivery box 3 and the delivery box 203 are described as being applied to a lead-acid battery 1 for a general vehicle, but they may be applied to a lead-acid battery 1 for an idling stop vehicle.

(11) In the above-mentioned second embodiment, no caution is written encouraging the user to place their hands in the first handle hole 41A when carrying the box, but this caution may be written further. Some delivery companies prohibit carrying the box by placing hands in handle holes, but since the delivery box 203 is a box used only for delivery, there is no problem with placing hands in the first handle hole 41A.
