[Technical Field]

[0001] SUMMARY OF THE INVENTION An embodiment of the present invention relates to a paper battery package. [Background technology]

[0002] Conventionally, cylindrical batteries (hereinafter referred to as batteries), such as lithium-ion batteries, nickel-metal hydride batteries, and alkaline batteries, are manufactured in factories and shipped in a battery storage package containing multiple batteries. Paper battery packages are sometimes used for transporting such batteries, due to the manufacturing cost and recyclability considerations.

[0003] In paper battery packages, if the paper absorbs moisture and comes into contact with the battery's electrode terminals, rust may form on the electrode terminals. To prevent this, some paper battery packages have a case that is folded or curved so that it does not come into contact with the electrodes. [Prior art documents] [Patent documents]

[0005] However, in the above-mentioned conventional technology, because the case is folded or curved so that it does not come into contact with the electrodes, there is a problem that it is difficult to store the paper battery package upright. For this reason, for example, when batteries transported in paper battery packages are to be displayed upright on a display shelf, it is difficult to display them while they are still in the package, and the batteries must be removed from the package before displaying them, which is labor-intensive.

[0006] In one aspect, an object is to provide a paper battery package that prevents the battery from rusting and allows for easy storage in an upright position. [Means for solving the problem]

[0007] One proposal is a box-shaped paper battery package that houses multiple cylindrical batteries with the same cylindrical direction, in which the box housing the cylindrical batteries has a tapered inner surface that abuts against the edge of the cylindrical batteries housed inside to support the cylindrical batteries, and an outer surface that corresponds to this inner surface. When the outer surface is the bottom, the outer surface of the box is flat, allowing the cylindrical direction of the cylindrical batteries housed inside to be vertical, allowing the box to stand upright. The box further includes a lid member that exposes the cylindrical battery housed inside when the outer surface is the bottom surface. [Effects of the Invention]

[0008] This prevents the battery from rusting and makes it easy to store it upright. [Brief explanation of the drawings]

[0010] Hereinafter, a paper battery package according to an embodiment will be described with reference to the drawings. Components having the same functions in the embodiments will be assigned the same reference numerals, and duplicated descriptions will be omitted. Note that the paper battery package described in the following embodiment is merely an example and does not limit the embodiment. Furthermore, the following embodiments may be combined as appropriate within a range that does not cause contradictions.

[0011] The paper battery package according to the embodiment can store multiple cylindrical batteries, such as LR6 (AA) and LR03 (AAA) batteries, inside, and also functions as a storage case for the cylindrical batteries after opening. Here, we will cite a paper battery package for storing multiple cylindrical batteries lined up with their cylindrical axes parallel to each other and aligned in the cylindrical direction.

[0012] The first embodiment described below is an example of a paper battery package that houses multiple cylindrical batteries of either LR6 (AA) or LR03 (AAA) type. The second and third embodiments are examples of a paper battery package that houses a mixture of two types of cylindrical batteries, LR6 (AA) and LR03 (AAA) type.

[0013] (First embodiment) Figure 1A is a perspective view of the appearance of a paper battery package according to a first embodiment, Figure 1B is a bird's-eye view showing the front appearance of the paper battery package according to the first embodiment, and Figure 1C is a bird's-eye view showing the side appearance of the paper battery package according to the first embodiment.

[0014] 1A to 1C all show the paper battery package 1 before opening, with ten cylindrical batteries stored inside. Here, the cylindrical axis direction of the cylindrical batteries stored in the paper battery package 1 is defined as the up-down direction (Z direction), and the up-down direction of the paper battery package 1 is also defined as the same direction as this cylindrical axis direction. The left-right direction (X direction) is defined as the ten cylindrical batteries stored in the paper battery package 1 standing upright with one electrode terminal facing either up or down, and arranged in parallel in the left-right direction (X direction). The direction perpendicular to the up-down, left-right, and right-left directions is defined as the front-rear direction (Y direction).

[0015] As shown in FIGS. 1A to 1C, the appearance of the paper battery package 1 is a box body 30 that is flat from front to back, and the front panel 20 of the box body 30 seals the flap portion 11 of the upper lid member 10. The outer surface of the bottom panel 22 of the box body 30 has a flat shape that is horizontal in the left-right and front-to-back directions (XY) when the box body 30 is stood upright in the vertical direction (Z direction). Therefore, when the outer surface of the bottom panel 22 is used as the bottom of the box body 30, the box body 30 stands upright with the cylindrical direction of the cylindrical batteries stored inside oriented vertically. In other words, the box body 30 is configured to be easily stored upright.

[0016] When sealed with the flap portion 11, the upper lid member 10 has a top plate 12 that slopes downward diagonally forward in the front-to-rear direction (Y direction). That is, in the paper battery package 1, the entire top surface of the cylindrical battery housed inside does not contact the top plate 12, but the edge portion at the top end of the cylindrical battery abuts against the top plate 12. Therefore, in the paper battery package 1, even if the paper material absorbs moisture, rust will not form on the electrode terminals of the cylindrical battery on the top plate 12 side.

[0017] The flap portion 11 of the upper lid member 10 is provided with insertion portions 11A, 11B that are inserted into insertion openings 21A, 21B provided in the front panel member 20 to seal the flap portion 11. These insertion portions 11A, 11B are connected to the flap portion 11 via zipper portions 13 that are notches on lines extending from both the left and right ends of the upper lid member 10. Therefore, the flap portion 11 of the upper lid member 10 can be opened by pulling the insertion portions 11A, 11B out of the insertion openings 21A, 21B or by breaking the zipper portion 13.

[0018] Fig. 2A is a bird's-eye view showing the front appearance of the paper battery package 1 according to the first embodiment. Fig. 2B is a bird's-eye view showing the top appearance of the paper battery package 1 according to the first embodiment. As shown in Figs. 2A and 2B, the upper cover member 10 can expose the inside of the paper battery package 1 by lifting the opened flap portion 11.

[0019] The box 30 has an open top so that the tops of the cylindrical batteries 2 housed inside are exposed. Therefore, with the paper battery package 1, the cylindrical batteries 2 inside can be easily removed by lifting the top lid 10. The top lid 10 can also be kept open by folding it behind the top panel 12 that connects to the box 30.

[0020] Fig. 3A is an overhead view showing the top appearance of the paper battery package 1 according to the first embodiment. Specifically, Fig. 3A shows the state after six of the ten cylindrical batteries 2 shown in Fig. 2B have been removed.

[0021] As shown in FIG. 3A, a divider plate 40 with insertion slots 41A-41E is provided inside the box 30. Each of the insertion slots 41A-41E holds two inserted cylindrical batteries 2 side-by-side in an upright position. The width of the opening of each of the insertion slots 41A-41E is large enough to hold two cylindrical batteries 2 side-by-side, and is narrow enough that removing one battery does not cause the remaining battery 2 to fall to the bottom. This prevents the remaining cylindrical batteries 2 from becoming difficult to remove even if the number of cylindrical batteries 2 housed in the box 30 decreases.

[0022] 2A, a semicircular cutout 11C is provided in the flap portion 11. After the zipper portion 13 is broken and opened, the tongue-shaped flap portion 11 can be resealed by inserting the cutout 11C into the insertion opening 21C of the front panel material 20.

[0023] Figure 3B is an overhead view showing the front appearance of the paper battery package according to the first embodiment. Specifically, Figure 3B illustrates the appearance of the paper battery package 1 after the zipper portion 13 has been torn off and opened, and the tongue-shaped flap portion 11 has been resealed. As shown in Figure 3B, when the tongue-shaped flap portion 11 has been resealed, the insertion portions 11A and 11B have been removed, making it easy to determine whether the paper battery package 1 is unopened or opened.

[0024] 4A is a plan view showing the backing sheet from which the paper battery package 1 according to the first embodiment is made. As shown in FIG. 4A, the box 30 is formed by folding a single sheet of backing sheet along the dotted lines and the dashed-dotted lines and assembling them. Specifically, the dashed-dotted line portion is folded back to surround the back panel 14 of the box 30, and the opposing joining surfaces A1 and A2 are bonded together to form flat housing portions on the front and back.

[0025] 4B and 4C are explanatory diagrams illustrating an example of assembly using the backing sheet that is the origin of the paper battery package 1 according to the first embodiment. Specifically, FIG. 4B is an overhead view showing the front appearance with flat housing sections formed on the front and back. FIG. 4C is an overhead view showing the rear appearance with flat housing sections formed on the front and back. As shown in FIGS. 4B and 4C, by folding back the back panel 14 so as to surround it and bonding the joining surfaces A1 and A2, flat housing sections are formed on the front and back to house the cylindrical batteries 2 side by side.

[0026] Next, in the box 30, the plate material 31 at the lower front surface of the formed housing portion is folded toward the inside of the box 30 to form an inner surface that abuts against and supports the ends of the cylindrical batteries 2 housed inside. Figure 5 is an explanatory diagram illustrating an example of assembling the plate material 31 in the paper battery package 1 according to the first embodiment.

[0027] As shown in Figure 5, the plate material 31 at the lower front of the housing portion is folded inward toward the inside of the box body 30 to form an inner surface that abuts against the vertically lower end of the cylindrical battery 2 to support it. Here, the plate material 31 is folded inward at an acute angle toward the inside of the box body 30. This forms a slope in the plate material 31, with the back panel 14 side higher and the front side lower, and the inner surface forms a tapered surface 31A that tapers toward the front side. This tapered surface 31A supports the cylindrical battery 2 stored inside the box body 30 by abutting against the vertically lower edge of the tube.

[0028] Furthermore, the end of the plate material 31 is folded back (downward) to the outside of the box body 30 at fold line 31B along the way to form folded plate material 31C. Specifically, the folded plate material 31C is formed by folding back at an acute angle toward the inside of the box body 30 and then folding back downward from fold line 31B where it abuts against the back panel 14. This folded plate material 31C functions as a support member that supports the load applied to the tapered surface 31A on the back panel 14 side.

[0029] Next, the bottom and front panels of the box 30 are formed by folding the bottom panel 22 and front panel 20 connected to the lower part of the back panel 14 of the formed housing portion forward. Specifically, the bottom panel 22 is folded at a right angle from the fold at the lower end of the back panel 14 toward the inside (front side) of the box 30. Next, the front panel 20 is folded at a right angle from the fold on the front side of the bottom panel 22. In the paper battery package 1, cylindrical batteries 2 are housed by inserting a partition plate 40 into the box 30 formed in this way.

[0030] Figure 6 is an explanatory diagram illustrating the storage of cylindrical batteries 2 in a paper battery package 1 according to the first embodiment. As shown in Figure 6, in the paper battery package 1, a divider plate 40 is inserted into a box 30 formed by assembling backing sheets. Next, two cylindrical batteries 2 are inserted into each of the insertion slots 41A to 41E of the divider plate 40, storing a total of ten cylindrical batteries 2. Next, in the paper battery package 1, the upper lid member 10 is folded back toward the front and the flap portion 11 is fastened, completing the boxing process with the ten cylindrical batteries 2 stored inside.

[0031] Here, the cylindrical batteries 2 are supported by the vertically lower edge of the tube abutting against the tapered surface 31A, so the electrode terminals on the vertically lower side of the cylindrical batteries 2 do not come into contact with the tapered surface 31A. Therefore, even if the paper material of the paper battery package 1 absorbs moisture, rust will not form on the electrode terminals on the vertically lower side of the cylindrical batteries 2 housed inside.

[0032] Additionally, the folded-over plate material 31C, which functions as a support for the load applied to the tapered surface 31A on the back plate 14 side, abuts its end against the bottom plate material 22 for support. As a result, even when the load of the cylindrical batteries 2 is applied to the tapered surface 31A, the support provided by the folded-over plate material 31C maintains the slope of the tapered surface 31A. This prevents electrode terminals located vertically below the cylindrical batteries 2 from coming into contact with the tapered surface 31A.

[0033] (Second embodiment) 7A and 7B are overhead views showing the front appearance of a paper battery package according to the second embodiment with the flap portion 11 open. As shown in Figures 7A and 7B, the paper battery package 1A is configured to house a mixture of two types of cylindrical batteries: LR6 (AA size) cylindrical batteries 2 and LR03 (AAA size) cylindrical batteries 3.

[0034] Specifically, as shown in Fig. 7A, the storage compartment 51 on the left side of the front, formed by a divider plate 50, accommodates LR6 (AA) cylindrical batteries 2. As shown in Fig. 7B, the storage compartment 52 on the right side of the front, also formed by a divider plate 50, accommodates LR03 (AAA) cylindrical batteries 3. The storage compartment 52 has a sealing lid 53 that slopes downward diagonally forward in the front-to-rear direction (Y direction). This prevents the entire top surface of the cylindrical battery 3 from coming into contact with paper, even for cylindrical batteries 3 that are shorter in the cylindrical axis direction than the cylindrical batteries 2.

[0035] Figure 8 is a bird's-eye view showing the front appearance of a divider plate 50 according to the second embodiment. As shown in Figure 8, the storage section 51 has sockets 51A to 51C. Each of the sockets 51A to 51C holds two inserted cylindrical batteries 2 side by side and in an upright position. The storage section 52 has sockets 52A to 52C. Each of the sockets 52A to 52C holds two inserted cylindrical batteries 3 side by side and in an upright position.

[0036] FIG. 9 is an explanatory diagram illustrating the storage of cylindrical batteries 2, 3 in a paper battery package 1A according to the second embodiment. As shown in FIG. 9, in the paper battery package 1A, a partition plate 50 is inserted into the box 30 formed by assembling backing sheets. Next, two cylindrical batteries 2 are inserted into each of the insertion slots 51A-51C of the storage section 51 of the paper battery package 1A, storing a total of six cylindrical batteries 2. Similarly, in the paper battery package 1A, two cylindrical batteries 3 are inserted into each of the insertion slots 52A-52C of the storage section 52, storing a total of six cylindrical batteries 3. Next, in the paper battery package 1A, the lid member 53 is folded back and locked to the front, and then the upper lid member 10 is folded back to the front and the flap member 11 is locked. This completes the packaging of the paper battery package 1A with six cylindrical batteries 2 and six cylindrical batteries 3 stored inside.

[0037] (Third embodiment) In the second embodiment, a configuration was illustrated in which the lid material 53 that covers the top end faces of the cylindrical batteries 3 is provided on the partition plate 50, but the lid material that covers the top end faces of the cylindrical batteries 3 may also be provided on the box body 30 side. Figure 10 is a plan view showing the backing sheet that is the origin of the paper battery package according to the third embodiment.

[0038] As shown in Figure 10, the mount has a lid 35 for covering the upper end surface of the cylindrical battery 3 at a position corresponding to the right front side when the dashed line portion is folded back to form a flat housing portion at the front and back.

[0039] 11 is an explanatory diagram illustrating an example of assembly of a backing sheet, which is the origin of a paper battery package according to the third embodiment. As shown in FIG. 11, the housing portion of the box body 30 is formed by folding back the back plate 14 to surround it and adhering the joining surfaces A1 and A2. Then, a lid member 35, which is folded inward when used, is placed on the right front side of this housing portion. The plate member 31 and the bottom plate member 22 are folded in the same manner as in the first embodiment.

[0040] Figure 12 is an explanatory diagram illustrating the storage of cylindrical batteries 2, 3 in a paper battery package according to the third embodiment. As shown in Figure 12, in a paper battery package 1B, a partition plate 60 is inserted into a box 30 formed by assembling backing sheets. The partition plate 60 has a storage section 61 with insertion openings 61A-61C for inserting two cylindrical batteries 2, and a storage section 62 with insertion openings 62A-62C for inserting two cylindrical batteries 3.

[0041] Next, in the paper battery package 1B, two cylindrical batteries 2 are inserted into each of the slots 61A-61C of the storage section 61, storing a total of six cylindrical batteries 2. Similarly, in the paper battery package 1B, two cylindrical batteries 3 are inserted into each of the slots 62A-62C of the storage section 62, storing a total of six cylindrical batteries 3. Next, in the paper battery package 1B, the lid member 35 is folded back and locked, and then the upper lid member 10 is folded back and locked to the front, and the flap portion 11 is locked. This completes the packaging of the paper battery package 1B with six cylindrical batteries 2 and six cylindrical batteries 3 stored inside.

[0042] As described above, the paper battery packages 1, 1A, and 1B are box-shaped packages that house multiple cylindrical batteries 2, 3 arranged with their cylindrical orientations aligned. The box body 30 of the paper battery packages 1, 1A, and 1B that houses the cylindrical batteries 2, 3 has a tapered inner surface (tapered surface 31A) that abuts against the cylindrical edges of the cylindrical batteries 2, 3 housed inside to support the batteries, and an outer surface that corresponds to the inner surface. When used as the bottom, this outer surface has a flat shape that allows the box body 30 to stand upright with the cylindrical orientation of the cylindrical batteries 2, 3 housed inside oriented vertically. This allows the paper battery packages 1, 1A, and 1B to protect the cylindrical batteries 2, 3 from rusting while facilitating storage of the cylindrical batteries 2, 3 in an upright position.

[0043] Box 30 has plate 31 that is folded at an acute angle toward the inside of box 30 to form the inner surface, and bottom plate 22 that is folded into plate 31 and then folded at a right angle toward the inside of box 30 to form the outer surface. This allows paper battery packages 1, 1A, 1B to be realized with a simple configuration by folding plate 31 and bottom plate 22, which is useful from the perspectives of, for example, manufacturing costs and recyclability.

[0044] Plate material 31 is folded toward the outside of box body 30 at crease 31B, which is partway up to the end where it is folded at an acute angle toward the inside of box body 30, so that the end abuts against bottom plate material 22, which is folded after plate material 31 is folded. This allows paper battery packages 1, 1A, 1B to support the load applied to tapered surface 31A of plate material 31 by the cylindrical batteries 2, 3 stored inside when box body 30 is erected, at the end of plate material 31.

[0045] When the outer surface of the box 30 that corresponds to the tapered inner surface is used as the bottom, the box 30 has an upper lid 10 that exposes the cylindrical batteries 2, 3 stored inside. This allows the cylindrical batteries 2, 3 to be stored upright in the paper battery packages 1, 1A, 1B, and allows the cylindrical batteries 2, 3 to be easily removed. [Explanation of symbols]
