Description

[Technical Field]

[0001] The present invention relates to a packaging box for packaging a heavy product and a packaging structure for a storage battery unit using the same. [Background technology]

[0002] Commonly known packaging boxes for packaging heavy products are Type A packaging boxes, which are cylindrical with a bottom and an open top, and Type C packaging boxes, which consist of a lower box that supports the packaged product and an upper box that covers the packaged product.

[0003] For example, Patent Document 1 discloses an A-type packaging box for precision instruments, which is made up of an outer box and an inner member interposed between the outer box and the precision instrument housed therein, with the sides of the outer box able to open like a hinged door, and the precision instrument secured to the inner member. This packaging box for precision instruments allows the precision instrument to be removed together with the inner member by opening the side of the outer box and using a handle on the inner member. Patent Document 2 also discloses an A-type packaging box with claw holes formed in the lower surface to allow for the insertion of forklift claws. Meanwhile, Patent Document 3 discloses a C-shaped packaging box that is made up of a packaging box main body and a bottom member that covers the bottom opening, and that is formed with a handle hole, an insertion piece for connecting the packaging box main body and the bottom member, and an insertion opening.Furthermore, Patent Document 4 discloses a packaging box for electronic devices that is made up of an upper packaging box and a lower packaging box, and that has cutouts for use with a forklift formed in the lower ends of the upper packaging box and the lower packaging box. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-101367 [Patent Document 2] Patent Publication No. 2021-31156 [Patent Document 3] Japanese Patent Application Laid-Open No. 2012-76820 [Patent Document 4] Japanese Patent Application Publication No. 11-301740 Summary of the Invention [Problem to be solved by the invention]

[0005] However, although the above-mentioned packaging boxes are designed for transportation by forklift, etc., the packaged product must be completely removed from the packaging box and then transported to the installation location. In this case, there is a possibility that the packaged product may be damaged during transportation to the installation location. For this reason, the packaged product is usually protected with a foam sheet or the like before being transported to the installation location. In the case of C-type packaging boxes, it is possible to cover the product with a top box again after removing it, but this requires the installation of cushioning materials and the like again, making the process complicated. The present invention was developed in consideration of the above circumstances, and aims to provide a packaging box and packaging structure that can be easily removed and installed without damaging the packaged items inside the packaging box. [Means for solving the problem]

[0006] The packaging box of the present invention comprises a lower box that supports the packaged product and an upper box that is placed over the lower box to cover the packaged product, wherein the lower box has a cylindrical lower box body and a bottom that closes its lower end, and the upper box has a cylindrical upper box body that partially overlaps with the lower box body, and when the lower box body and the upper box body are stacked on top of each other, at least the upper box body has a first hole and a second hole that form a penetration portion through which a transport tool can be inserted that crosses the interior, and the packaged product covered by the upper box can be separated from the lower box by the transport tool inserted through the penetration portion.

[0007] In the packaging box of the present invention, when the lower box body and the upper box body are stacked, a carrying tool can be passed through the interior of the packaging box by passing it from the first hole (second hole) forming the through-hole toward the second hole (first hole). In other words, the carrying tool can be passed under the packaged product stored in the packaging box. Then, the upper box and the packaged product can be removed from the lower box simply by using the carrying tool to lift the packaged product covered by the upper box. Because the packaged product can be removed while still attached to the upper box, the packaged product can be transported to the installation position with the upper box attached. In other words, after removing the packaged product from the packaging box, there is no need to provide additional protection for the packaged product before moving it. Finally, after moving it to the installation position and placing the packaged product, the upper box can be removed, allowing the packaged product to be easily installed. Note that ropes, bands, belts, etc. can be used as the carrying tool.

[0008] In the packaging box of the present invention, it is preferable that the lower box body has a pair of first lower box perforation lines extending downward from the open upper end and a pair of second lower box perforation lines extending downward from the open upper end, and the upper box body has a pair of first upper box perforation lines extending upward from the open lower end and a pair of second upper box perforation lines extending upward from the open lower end, and a first lower box flap, a second lower box flap, a first upper box flap, and a second upper box flap can be formed by breaking the first lower box perforation lines, the second lower box perforation lines, the first upper box perforation lines, and the second upper box perforation lines, respectively, and that the first hole is formed by opening the first lower box flap and the first upper box flap, and the second hole is formed by opening the second lower box flap and the second upper box flap. In this case, by breaking each of the perforations and opening each of the flaps, a penetration can be formed in the bottom of the packaging box.

[0009] In the packaging box of the present invention, it is preferable that the first hole and the second hole are formed by cutting out the lower box body and the upper box body, respectively. The packaging structure for a storage battery unit of the present invention is characterized by including a storage battery unit as the packaged product and the packaging box of the present invention. [Effects of the Invention]

[0010] The packaging box of the present invention allows heavy packaged products to be easily removed at the site, and after removal, the packaged products can be transported to the installation location while being protected by the upper box. [Brief explanation of the drawings]

[0012] Next, a battery unit packaging structure of the present invention will be described based on an embodiment.

[0013] "Storage battery unit packaging structure 1 (first embodiment)" The storage battery unit packaging structure 1 of FIG. 1 includes a storage battery unit 10 and a packaging box 100 that houses the storage battery unit.

[0014] "Storage Battery Unit 10" As shown in Fig. 2, the storage battery unit 10 has a gap 15 penetrating downward from front to back. More specifically, the storage battery unit 10 has a storage battery body 11 and a pair of support legs 12 that support the storage battery body 11, and a gap 15 penetrating downward from front to back is provided between the support legs 12. In this embodiment, the packaged product will be described mainly as a storage battery unit. However, the packaged product of the present invention is not particularly limited as long as it is heavy and difficult to carry by one person and has a gap penetrating in any direction in the main body (particularly the bottom of the main body). Examples include precision machinery such as printers, large water heaters, and refrigerators. Furthermore, even in the case of a product with a flat bottom that does not have support legs 12, if packaging materials (such as polystyrene or cardboard pads) are placed in place of support legs 12, gap 15 will be formed between the packaging materials (below the packaged product), and the present invention can be applied.

[0015] "100 packing boxes" 1b, the packing box 100 has a lower box 110 that supports the storage battery unit 10, and an upper box 120 that is placed over the lower box 110 to cover the storage battery unit 10. The packing box 100 is assembled by overlapping the lower part of the upper box 120 on the outside of the lower box 110.

[0016] "Lower box 110" As shown in Figure 3a, lower box 110 has a cylindrical lower box main body 111 and a bottom surface 112 that closes the bottom end. In other words, lower box 110 (or lower box main body 111) is open at the top end. Cylindrical lower box main body 111 has a rectangular cross-sectional shape (opening shape) and is composed of four walls: lower box front wall 111a, lower box rear wall 111b, lower box left wall 111c, and lower box right wall 111d. Bottom surface 112 also has a rectangular shape that closes lower box main body 111.

[0017] Lower box front wall 111a has a pair of first lower box perforations 115a, 115b extending downward from the upper end. More specifically, first lower box perforations 115a, 115b are provided on either side of the left-right center of lower box front wall 111a, at the same distance from the center, and the pair of first lower box perforations 115a, 115b is provided across the entire height of lower box front wall 111a. Therefore, by breaking the pair of first lower box perforations 115a, 115b, first lower box flap 118 is formed that can be folded from top to bottom between the pair of first lower box perforations 115a, 115b, as shown in FIG. 3b. Lower box rear wall 111b has a pair of second lower box perforations 116a, 116b extending downward from the upper end (see FIG. 3a). More specifically, second lower box perforations 116a, 116b are provided on either side of the left-right center of lower box rear wall 111b, at the same distance from the center, and the pair of second lower box perforations 116a, 116b are provided across the entire height of lower box rear wall 111b. Therefore, by breaking the pair of second lower box perforations 116a, 116b, second lower box flap 119 is formed that can be folded from top to bottom between the pair of second lower box perforations 116a, 116b (see FIG. 3b).

[0018] "Upper box 120" As shown in Figure 3c, upper box 120 has a cylindrical upper box main body 121 and a top surface 122 that closes the top end. In other words, upper box 120 (or upper box main body 121) is open at the bottom end. Cylindrical upper box main body 121 has a rectangular cross-sectional shape (opening shape) similar to that of lower box main body 111, and is composed of four walls: upper box front wall 121a, upper box rear wall 121b, upper box left wall 121c, and upper box right wall 121d. Top surface 122 also has a rectangular shape that closes the top end of upper box main body 121. Upper box body 121 receives lower box body 111 therein, and the lower parts of upper box front wall 121a, upper box rear wall 121b, upper box left wall 121c, and upper box right wall 121d are arranged outside lower box front wall 111a, lower box rear wall 111b, lower box left wall 111c, and lower box right wall 111d. Note that "the cross-sectional shape of upper box body 121 is similar to the cross-sectional shape of lower box body 111" also includes the cross-sectional shape of upper box body 121 being substantially the same as the cross-sectional shape of lower box body 111, so that lower box body 111 can be inserted into upper box body 121.

[0019] Upper box front wall 121a has a pair of first upper box perforations 125a, 125b extending upward from the bottom edge. Specifically, first upper box perforations 125a, 125b are provided at equal distances from the left-right center of upper box front wall 121a, and the pair of first upper box perforations 125a, 125b are the same length. By breaking the pair of first upper box perforations 125a, 125b, a first upper box flap 128 is formed that can be folded upward between the pair of first upper box perforations 125a, 125b, as shown in FIG. 3d. It is preferable that first upper box perforations 125a, 125b be positioned at the same distance as or slightly longer than (outside of) first lower box perforations 115a, 115b (i.e., outward from the center). The length of first upper box cutout lines 125a, 125b is preferably the same as or slightly longer than first lower box cutout lines 115a, 115b. By enlarging the shape of first upper box flap 128 on the outside, first lower box cutout line 115 of lower box 110 on the inside can be easily broken, and first lower box flap 118 can also be easily folded. Upper box rear wall 121b has a pair of second upper box perforations 126a, 126b extending upward from the lower end (see FIG. 3c). More specifically, second upper box perforations 126a, 126b are provided at equal distances from the left-right center of upper box rear wall 121b, and the pair of second lower box perforations 126a, 126b are the same length. First lower box perforations 125a, 125b and second upper box perforations 126a, 126b are also the same length. Therefore, by breaking the pair of second upper box perforations 126a, 126b, a second upper box flap 129 is formed that can be folded upward between the pair of second upper box perforations 126a, 126b (see FIG. 3d). Second upper box cutout lines 126a, 126b are preferably positioned the same distance as or slightly longer (outside of the center) than second lower box cutout lines 116a, 116b. Second upper box cutout lines 126a, 126b are preferably the same length as or longer than second lower box cutout lines 116a, 116b. As with first upper box flap 128, by enlarging the shape of second upper box flap 129 on the outside, it becomes easier to break second lower box cutout line 116a on the inside and fold second lower box flap 119.

[0020] 4a, in the packing box 100 configured in this manner, a first hole 108 is formed in the front lower portion from a first lower box-side notch in the front wall of the lower box whose upper end is opened by opening first lower box flap 118 and a first upper box-side notch in the front wall of the upper box whose lower end is opened by opening first upper box flap 128, and a second hole 109 is formed in the rear lower portion from a second lower box-side notch in the rear wall of the lower box whose upper end is opened by opening second lower box flap 119 and a second upper box-side notch in the rear wall of the upper box whose upper end is opened by opening second upper box flap 129. In other words, the first hole 108 and the second hole 109 in the packing box 100 are formed at a position where the lower box 110 and the upper box 120 overlap. The first hole 108 and the second hole 109 form a through portion 105 in the packing box 100. This through-hole 105 overlaps with the gap 15 of the storage battery unit 10 supported by the lower box 110. Therefore, as shown in Fig. 4b, the carrying rope R can be passed under the storage battery unit 10 by inserting it through the first hole 108 or the second hole 109 and pulling it out through the through-hole 105 and out the second hole 109 or the first hole 108. Then, as shown in FIG. 4c, the transporter can use the transport rope R to lift the storage battery unit 10 and remove it from the lower box 110. At this time, the upper box 120 remains attached to the storage battery unit 10. Therefore, after the product is removed, the storage battery unit 10 can be protected by the upper box 120 until it is transported or installed. Finally, after transportation or surrounding transportation is completed, or immediately before use, the upper box 120 is removed from the storage battery unit 10, completing the product installation (see FIG. 4d). In this way, the packaging box 100 allows the packaged product to be easily removed from the packaged state, and the packaged product can be transported to the installation location without being damaged after removal. It goes without saying that instead of the transport rope R, transport equipment such as bands, belts, etc. can be used.

[0021] [Other variations] In the packaging box 100 of FIG. 1, perforations are provided so that the flaps are formed in the center of the respective walls, but the positions of the pair of perforations are not particularly limited. In the packaging box 100 of Fig. 1, each flap is rectangular, but the shape is not particularly limited. Also, although one flap is provided on each wall, as in the packaging box 100A of Fig. 5a, perforations may be provided on each wall (for example, first upper box flaps 128a, b, second upper box flaps 129a, b) so that two or more flaps can be provided, thereby providing two or more penetrations that penetrate the packaging box. Also, the number of flaps on each wall may be different. 1 is configured so that the lower box 110 is inserted into the upper box 120, but it may also be configured so that the upper box 120 is inserted into the lower box 110. In this case, by enlarging the shape of the outer flaps, it becomes easier to break the inner perforation lines and fold the flaps. In the packaging box 100 of FIG. 1, the cross-sectional shapes of the lower box body 111 and the upper box body 121 are similar to each other, but they may have different shapes. In the packaging box 100 of Fig. 1, the cross-sectional shapes of the lower box body 111 and the upper box body 121 are rectangular, but the cross-sectional shapes may be circular, triangular (not shown), or pentagonal or higher (not shown) as in the packaging box 100B of Fig. 5b. Note that, as in the packaging box 100B of Fig. 5b, the upper end of the upper box 120 may be open and closed with a separate lid C. 1 has flaps formed on lower box body 111 and upper box body 121, but as in packaging box 100C in FIG. 5c, a pair of lower box-side cutouts in lower box body 111 and a pair of upper box-side cutouts in upper box body 121 may serve as first hole 108 and second hole 109 without providing flaps. In this case as well, first hole 108 or second hole 109 forms through-hole 105. Note that the lower box-side cutouts in lower box body 111 and the upper box-side cutouts in upper box body 121 may be closed with a lid or the like before use, and the lid may be designed to be rupturable along a perforation line, for example, or a separate member such as a sticker may be used. In the packaging box 100 of FIG. 1, the first and second holes are provided at the overlapping positions of the lower box 110 and the upper box 120, respectively, and are formed by both the lower box 110 and the upper box 120. However, as in the packaging box 100D of FIG. 5d, the first and second holes 108A and 109A may be formed only in the upper box 120. That is, the pair of upper box-side cutouts (first and second holes 108A and 109A) of the upper box 120 are provided at least above the upper end of the lower box 110. In this case, the first and second holes 108A and 109A form the through-hole 105. Note that while the cutouts in the upper box 120 are rectangular, they may be closed shapes such as polygons or circles, or may have an open bottom. Furthermore, a cutout line may be provided in the upper box body 121 in the shape of the upper box-side cutout, and the upper box may be closed with a lid or flap before use.
