（本実施形態の概要）
　（１）本発明の一側面によれば、梱包箱付き蓄電池は、蓄電池と、前記蓄電池を梱包する梱包箱と、を備え、前記蓄電池は、電極体と、前記電極体を収容する収容体と、を備え、前記収容体は、収容体側壁に 第１の凸部を有し、前記梱包箱は、梱包箱底壁と、梱包箱側壁と、を備え、前記梱包箱側壁は、側壁フラップを備え、前記側壁フラップは、前記梱包箱の内部に折り曲げ可能であり、折り曲げた状態において、少なくとも一部が、前記蓄電池の前記第１の凸部の鉛直方向の下面に接する。 (Summary of this embodiment)
(1) According to one aspect of the present invention, a storage battery with a packaging box includes a storage battery and a packaging box for packaging the storage battery, and the storage battery includes an electrode body and a container that houses the electrode body. , the container has a first protrusion on a side wall of the container, the packaging box includes a bottom wall of the packaging box, and a side wall of the packaging box, and the side wall of the packaging box includes a side wall flap. The side wall flap can be folded into the packaging box, and in the folded state, at least a portion of the side wall flap is in contact with a vertical lower surface of the first convex portion of the storage battery.
　上記の梱包箱付き蓄電池によると、作業者が側壁フラップを把持して蓄電池を持ち上げる場合、蓄電池の荷重は、第１の凸部を介して側壁フラップの面に掛かる。作業者の指先に掛かる蓄電池の荷重が、側壁フラップの面に分散されるため、安定して持ち上げることができる。これにより、梱包箱付き蓄電池の持ち易さが向上する。 According to the storage battery with a packaging box described above, when an operator lifts the storage battery by grasping the side wall flap, the load of the storage battery is applied to the surface of the side wall flap via the first convex portion. The load of the storage battery placed on the operator's fingertips is distributed over the side wall flap surface, allowing for stable lifting. This improves the ease of holding the storage battery with the packaging box.
　（２）本発明の一側面によれば、梱包箱付き蓄電池において、側壁フラップは、梱包箱側壁と繋がっている箇所に形成された折線を起点に、梱包箱内部に折れ曲がり、折線は、上下方向で、第１の凸部の下面と同じ又は下面より低い位置に設けられていてもよい。 (2) According to one aspect of the present invention, in the storage battery with a packaging box, the side wall flap is bent into the packaging box starting from a fold line formed at a point connected to the side wall of the packaging box, and the fold line is in the vertical direction. The first convex portion may be provided at the same position as or lower than the lower surface of the first convex portion.
　このような構成では、第１の凸部の下面に接するように折り曲げられた状態の側壁フラップは、水平又は梱包箱の内側に向かって上方に傾斜する。側壁フラップが水平又は内側に向かって上方に傾斜していると、作業者が梱包箱の外側から側壁フラップを把持する場合に、指先が梱包箱の外側に向かって滑りにくく、蓄電池をより安定して持ち上げることができる。 In such a configuration, the side wall flap that is bent so as to be in contact with the lower surface of the first convex portion is horizontal or inclined upward toward the inside of the packaging box. If the side wall flap is horizontal or slopes upward toward the inside, when a worker grasps the side wall flap from the outside of the packaging box, his or her fingertips will be less likely to slip toward the outside of the packaging box, making the battery more stable. It can be lifted up.
　（３）本発明の一側面によれば、梱包箱付き蓄電池において、側壁フラップは、梱包箱の内部に折り曲げた状態において、側壁フラップの先端が、収容体側壁に接触してもよい。 (3) According to one aspect of the present invention, in the storage battery with a packaging box, the tip of the side wall flap may contact the side wall of the container when the side wall flap is bent into the packaging box.
　梱包箱を持ち上げる際に側壁フラップが第１の凸部を乗り越えて上方に回動すると、鉛蓄電池の荷重が、側壁フラップには掛からない。したがって、梱包箱付き蓄電池を持ち易くすることができるという効果を得ることが難しい。一方、本発明の一側面に係る構成では、側壁フラップが、第１の凸部の基端側である収容体側壁に接触しているため、第１の凸部を乗り越えて上方に回動しにくい。これにより、側壁フラップに蓄電池の荷重が掛かりやすくなるため、蓄電池をより安定して持ち上げることができる。 When the side wall flap rotates upward over the first convex portion when lifting the packaging box, the weight of the lead-acid battery is not applied to the side wall flap. Therefore, it is difficult to obtain the effect of making the packaging box with the storage battery easier to hold. On the other hand, in the configuration according to one aspect of the present invention, the side wall flap is in contact with the container side wall, which is the base end side of the first convex portion, and therefore is less likely to rotate upward over the first convex portion. This makes it easier for the weight of the storage battery to be applied to the side wall flap, allowing the storage battery to be lifted more stably.
　（４）本発明の一側面によれば、梱包箱付き蓄電池において、側壁フラップの、基端から先端までの長さは、梱包箱側壁から収容体側壁までの距離よりも大きくてもよい。側壁フラップの一部は確実に収容体側壁に接触できるため、側壁フラップが第１の凸部を乗り越えて上方に回動することを抑制できる。このため、側壁フラップに蓄電池の荷重が掛かりやすくなり、蓄電池をより安定して持ち上げることができる。 (4) According to one aspect of the present invention, in the storage battery with a packaging box, the length of the side wall flap from the base end to the tip may be greater than the distance from the packaging box side wall to the container side wall. Since a portion of the side wall flap can reliably contact the side wall of the container, it is possible to suppress the side wall flap from climbing over the first convex portion and rotating upward. Therefore, the load of the storage battery is easily applied to the side wall flap, and the storage battery can be lifted more stably.
　（５）本発明の一側面によれば、梱包箱付き蓄電池において、前記側壁フラップは、前記基端と前記先端との間に中間点を有し、前記側壁フラップが前記梱包箱の内部に折り曲げられた状態において、前記基端から前記中間点までの部分は、前記第１の凸部の鉛直方向の下面に接し、前記中間点から前記先端までの部分は、前記収容体側壁に接触してもよい。 (5) According to one aspect of the present invention, in the storage battery with a packaging box, the side wall flap has an intermediate point between the base end and the tip, and the side wall flap is bent into the inside of the packaging box. In this state, the portion from the base end to the intermediate point is in contact with the vertical lower surface of the first convex portion, and the portion from the intermediate point to the tip is in contact with the side wall of the container. Good too.
　上記構成によれば、側壁フラップを、基端から中間点までの部分が第１の凸部の下面に接触した状態よりさらに内側に回動させようとしても、中間点から先端にかけての部分が第１の凸部の下面で引っ掛かり、回動しにくい。これにより、側壁フラップが第１の凸部を乗り越えて回動することが妨げられる。これにより、梱包箱付き蓄電池を、さらに安定して持ち上げることができる。 According to the above configuration, even if the side wall flap is to be rotated further inward from the state in which the portion from the base end to the middle point contacts the lower surface of the first convex portion, the portion from the middle point to the tip will be rotated further inward. It gets caught on the bottom surface of the convex part 1 and is difficult to rotate. This prevents the side wall flap from rotating over the first protrusion. Thereby, the storage battery with packaging box can be lifted more stably.
　（６）本発明の一側面によれば、梱包箱付き蓄電池において、前記収容体側壁は、上下方向で、前記第1の凸部より低い位置に第２の凸部を有し、前記側壁フラップは、前記基端と前記先端との間に中間点を有し、前記側壁フラップが前記梱包箱の内部に折り曲げられた状態において、前記基端から前記中間点までの部分は、前記第１の凸部の鉛直方向の下面に接し、前記先端は、前記中間点よりも前記収容体側壁から離れた位置にあってもよい。 (6) According to one aspect of the present invention, in the storage battery with a packaging box, the container side wall has a second protrusion at a position lower than the first protrusion in the vertical direction, and the side wall flap has an intermediate point between the base end and the distal end, and when the side wall flap is bent inside the packaging box, the portion from the base end to the intermediate point is the first point. The tip may be in contact with the lower surface of the convex portion in the vertical direction, and may be located at a position farther from the container side wall than the intermediate point.
　上記構成によれば、梱包箱付き蓄電池を持ち上げる際には、作業者の指先に掛かる蓄電池の荷重が、側壁フラップの面に分散されるため、安定して持ち上げることができる。これに加えて、蓄電池を梱包箱から取り出す際に、第２の凸部が下方から側壁フラップに接触しても、側壁フラップが折りたたまれるように変形することにより、蓄電池の取り出しが容易になる。 According to the above configuration, when lifting the storage battery with a packing box, the load of the storage battery on the fingertips of the operator is dispersed on the surface of the side wall flap, so that the storage battery can be lifted stably. In addition, even if the second convex portion contacts the side wall flap from below when taking out the storage battery from the packaging box, the side wall flap is deformed so as to be folded, making it easy to take out the storage battery.
　（７）本発明の別の側面によれば、蓄電池用の梱包箱は、収容体の収容体側面壁に第１の凸部を有する蓄電池を梱包し、梱包箱底壁と、梱包箱側壁と、を備え、梱包箱側壁は、側壁フラップを備え、側壁フラップは、梱包箱内部に折り曲げ可能であり、折り曲げた状態において、少なくとも一部が、蓄電池の第１の凸部の鉛直方向の下面に接する。 (7) According to another aspect of the present invention, a packaging box for a storage battery packs a storage battery having a first convex portion on a side wall of the storage body, and includes a bottom wall of the packaging box, a side wall of the packaging box, The side wall of the packaging box includes a side wall flap, and the side wall flap is foldable into the packaging box, and in the folded state, at least a portion thereof is in contact with the vertical lower surface of the first convex portion of the storage battery. .
　上記の蓄電池用の梱包箱によると、作業者が側壁フラップを把持して蓄電池を梱包した梱包箱を持ち上げる場合、蓄電池の荷重は、第１の凸部を介して側壁フラップの面に掛かる。これにより、作業者の指先に掛かる蓄電池の荷重が、側壁フラップの面に分散されるため、安定して持ち上げることができる。したがって、蓄電池が入った梱包箱の持ち易さが向上する。 According to the storage battery packaging box described above, when a worker grasps the side wall flap and lifts the packaging box in which the storage battery is packed, the load of the storage battery is applied to the surface of the side wall flap via the first convex portion. Thereby, the load of the storage battery on the fingertips of the worker is dispersed over the surface of the side wall flap, so that the worker can lift the battery stably. Therefore, the ease of holding the packaging box containing the storage battery is improved.

Inside the battery case 12, five partition walls 15 are formed at equal intervals in the left-right direction. The partition walls 15 divide the interior of the battery case 12 into six cell chambers 19.

The convex portion 20A is a protrusion provided on the side wall 20 of the battery case, and is one of the structures defined by the EN standard. The convex portion 20A is provided for hooking the claws of the robot hand when the lead-acid battery 10 is gripped by the robot hand, and is also called a robot grip. The battery case side wall 20 and the convex portion 20A are formed by integrally molding the battery case 12.
　凸部２０Ａは、電槽側壁２０の板面の前方側と後方側に１つずつ、底面からの高さが同じ位置に設けられている。図３に示すように、凸部２０Ａは、電槽１２と蓋部材１３を接着した状態では、蓋部材１３の最外周から垂下しているフランジ部１３Ａの下端よりも下方に位置している。 The convex portions 20A are provided one each on the front side and the rear side of the plate surface of the battery case side wall 20, at the same height from the bottom surface.

　極板群２３は、正極板２３Ａと負極板２３Ｂとを、間にセパレータ２３Ｃを挟んで左右方向に交互に積層したものである。各極板２３Ａ、２３Ｂは格子体に活物質が充填されたものである。 The electrode plate group 23 is made by alternately stacking positive electrode plates 23A and negative electrode plates 23B in the left-right direction with separators 23C in between. Each of the electrode plates 23A and 23B has a grid filled with an active material.
　図３に示すように、極板群２３の上端に設けられた耳部２５は、同じ極性の耳部２５ごとに、ストラップ２６と接合している。ストラップ２６はセル室１９ごとに正極用と負極用とが一組設けられている。 As shown in FIG. 3, the ears 25 provided at the upper end of the electrode plate group 23 are joined to the straps 26 for each ear 25 of the same polarity.

　梱包箱側壁４１の上寄りの位置には、側壁フラップ４５が形成されている。側壁フラップ４５は、水平方向に延びる長円形状（２本の平行線と２つの半円とで構成される形状）の下端を、水平方向に切り落とした形状である。側壁フラップ４５は、基端４５Ａ（２本の平行線のうち、上方に位置する平行線）でのみ、梱包箱側壁４１と繋がっており、先端４５Ｂ（下方に位置する平行線）および２つの半円部分は、梱包箱側壁４１の厚み方向に切断されている。側壁フラップ４５の基端４５Ａから先端４５Ｂまでの最短長さを、フラップ長Ｌ１とする。 A side wall flap 45 is formed at an upper position of the packaging box side wall 41. The side wall flap 45 has a shape in which the lower end of a horizontally extending oval shape (a shape composed of two parallel lines and two semicircles) is cut off in the horizontal direction. The side wall flap 45 is connected to the packaging box side wall 41 only at the base end 45A (the parallel line located above of the two parallel lines), and is connected to the packaging box side wall 41 only at the base end 45A (the parallel line located below) and the two halves. The circular portion is cut in the thickness direction of the packaging box side wall 41. The shortest length from the base end 45A to the tip 45B of the side wall flap 45 is defined as the flap length L1.
　側壁フラップ４５の基端４５Ａと重なる位置に、ミシン目などからなる折線４５Ｃが、予め形成されている。作業者が鉛蓄電池１０を梱包した梱包箱４０を持つときに、側壁フラップ４５を梱包箱４０の内側に押し込むと、折線４５Ｃを起点として側壁フラップ４５が内側に折り曲げられ、手掛け穴４５Ｄ（図５参照）が形成される。図５等に示す断面視において、折り曲げた状態の側壁フラップ４５と、折線４５Ｃを起点とする下方向のなす角Ａ（図示せず）は、９０°以上であることが好ましい。すなわち、側壁フラップ４５が折り曲げられて回動する角度は９０°以上であることが好ましい。これにより、鉛蓄電池の荷重が確実に側壁フラップにかかるので、梱包箱付き鉛蓄電池が持ち易くなる。 A fold line 45C consisting of a perforation or the like is formed in advance at a position overlapping the base end 45A of the side wall flap 45. When an operator holds the packaging box 40 in which the lead-acid battery 10 is packed and pushes the side wall flap 45 inside the packaging box 40, the side wall flap 45 is bent inward starting from the fold line 45C, and the handle hole 45D (Fig. 5 ) is formed. In the cross-sectional view shown in FIG. 5 and the like, it is preferable that an angle A (not shown) formed between the bent side wall flap 45 and the downward direction starting from the fold line 45C is 90° or more. That is, it is preferable that the angle at which the side wall flap 45 is bent and rotated is 90 degrees or more. This ensures that the load of the lead-acid battery is applied to the side wall flaps, making it easier to hold the lead-acid battery with the packaging box.
　また、上下方向において、梱包箱側壁４１における折線４５Ｃの位置は、梱包箱４０に鉛蓄電池１０を収容したときに、凸部２０Ａの下面と同じ又は下面より低い位置に設定される。つまり、上下方向における側壁フラップ４５の基端４５Ａの位置は、凸部２０Ａの下面と同じか、下面よりも低い。 Further, in the vertical direction, the position of the fold line 45C on the packaging box side wall 41 is set to be the same as or lower than the lower surface of the convex portion 20A when the lead acid battery 10 is housed in the packaging box 40. That is, the position of the base end 45A of the side wall flap 45 in the vertical direction is the same as or lower than the lower surface of the convex portion 20A.
（３）梱包箱付き蓄電池の効果
　図５を参照して、実施形態１に係る梱包箱付き蓄電池１について説明する。梱包箱付き蓄電池１は、梱包箱４０に梱包された鉛蓄電池１０を持ち易くするための構成である。 (3) Effects of the storage battery with a packaging box The storage battery 1 with a packaging box according to the first embodiment will be described with reference to FIG. The storage battery 1 with a packaging box is configured to make it easier to hold the lead acid battery 10 packed in the packaging box 40.
　側壁フラップ４５のフラップ長をＬ１とする。電槽側壁２０と、電槽側壁２０に対向する梱包箱側壁４１との距離を距離Ｄ１とする。まず、フラップ長Ｌ１が、距離Ｄ１と等しい場合について説明する。 Let the flap length of the side wall flap 45 be L1. The distance between the battery case side wall 20 and the packaging box side wall 41 facing the battery case side wall 20 is defined as a distance D1. First, a case where the flap length L1 is equal to the distance D1 will be described.
　梱包箱４０の内部に鉛蓄電池１０を収容した後に、側壁フラップ４５を、折線４５Ｃを起点として内側に折り曲げる。フラップ長Ｌ１が距離Ｄ１と等しいため、側壁フラップ４５の先端４５Ｂは、電槽側壁２０に接触する。また、上下方向において、折線４５Ｃと、凸部２０Ａの下面が同じ高さに位置するため、側壁フラップ４５が９０°回動すると、側壁フラップ４５が凸部２０Ａの下面に当接して、それ以上回動できなくなる。このとき、側壁フラップ４５は水平になっている。 After storing the lead-acid battery 10 inside the packaging box 40, the side wall flap 45 is bent inward starting from the fold line 45C. Since the flap length L1 is equal to the distance D1, the tip 45B of the side wall flap 45 contacts the battery case side wall 20. In addition, since the fold line 45C and the lower surface of the convex portion 20A are located at the same height in the vertical direction, when the side wall flap 45 rotates 90 degrees, the side wall flap 45 comes into contact with the lower surface of the convex portion 20A. It becomes impossible to rotate. At this time, the side wall flap 45 is horizontal.
　この状態で、作業者が手掛け穴４５Ｄに指先を挿入し、側壁フラップ４５に指先を掛けて梱包箱付き蓄電池１を持ち上げる。鉛蓄電池１０の荷重は、凸部２０Ａを介して側壁フラップ４５に掛かる。作業者は、側壁フラップ４５の面に力を掛けて持ち上げればよい。作業者の指先が凸部２０Ａに直接掛かる場合と比べ、指先の接触面積が大きいため、安定して持ち上げることができる。これにより、梱包箱付き蓄電池１の持ち易さが向上する。 In this state, the operator inserts his fingertip into the hand hole 45D, hangs his fingertip on the side wall flap 45, and lifts the storage battery 1 with packaging box. The load of the lead acid battery 10 is applied to the side wall flap 45 via the convex portion 20A. The operator only has to apply force to the surface of the side wall flap 45 and lift it. Since the contact area of the worker's fingertips is larger than that in the case where the worker's fingertips directly hang on the convex portion 20A, it is possible to lift it stably. This improves the ease of holding the storage battery 1 with packaging box.
　梱包箱付き蓄電池１の構成によると、側壁フラップ４５を形成するにあたり、梱包箱４０の部品点数は増加せず、また、手掛け穴４５Ｄも、元々梱包箱４０に形成されているため、加工工数は増加しない。さらに、凸部２０Ａは、ＥＮ規格の鉛蓄電池１０に元々形成されており、鉛蓄電池１０の仕様を変更しなくても凸部２０Ａは形成されている。したがって、コストや工数を増加させずに、持ち易さを向上させることができる。 According to the configuration of the storage battery 1 with a packaging box, when forming the side wall flap 45, the number of parts of the packaging box 40 does not increase, and the hand hole 45D is also originally formed in the packaging box 40, so the number of processing steps is reduced. Does not increase. Further, the convex portion 20A is originally formed in the lead acid battery 10 of EN standard, and the convex portion 20A can be formed without changing the specifications of the lead acid battery 10. Therefore, ease of holding can be improved without increasing cost or man-hours.
　電槽１２と蓋部材１３は、熱溶着により接着されている。これに対し、電槽側壁２０と凸部２０Ａは、一体成形により形成されており、熱溶着と比べて強度が高い。そのため、例えば蓋部材１３のフランジ部１３Ａの下面に側壁フラップ４５を引っ掛けて、鉛蓄電池１０の荷重が掛かる場合と比べると、凸部２０Ａに鉛蓄電池１０の荷重が掛かる場合の方が、荷重がかかった部分が破損した場合に、希硫酸等の鉛蓄電池の内容物が漏れ出すおそれが低い。 The battery case 12 and the lid member 13 are bonded together by thermal welding. On the other hand, the battery case side wall 20 and the convex portion 20A are formed by integral molding, and have higher strength than those formed by thermal welding. Therefore, compared to the case where the load of the lead-acid battery 10 is applied by hooking the side wall flap 45 on the lower surface of the flange part 13A of the lid member 13, for example, the load is smaller when the load of the lead-acid battery 10 is applied to the convex part 20A. There is a low risk that the contents of the lead-acid battery, such as dilute sulfuric acid, will leak out if the affected part is damaged.
　梱包箱付き蓄電池１の構成によると、折線４５Ｃは、上下方向で、凸部２０Ａの下面の高さ以下に設けられている。上記の例（図５）では、折線４５Ｃの高さと、凸部２０Ａの下面の高さは同じである。この場合、側壁フラップ４５は９０°回動して水平な姿勢で凸部２０Ａの下面に当接する。 According to the configuration of the storage battery 1 with a packaging box, the fold line 45C is provided below the height of the lower surface of the convex portion 20A in the vertical direction. In the above example (FIG. 5), the height of the broken line 45C and the height of the lower surface of the convex portion 20A are the same. In this case, the side wall flap 45 rotates by 90 degrees and comes into contact with the lower surface of the convex portion 20A in a horizontal position.
　また、図６の梱包箱付き蓄電池２では、上下方向において、梱包箱側壁１４１の折線１４５Ｃは、凸部２０Ａの下面より下の位置に設けられている。この場合、側壁フラップ１４５は９０°以上回動し、梱包箱４０の内側に向かって上方に傾斜する。フラップ長Ｌ２は、距離Ｄ１と同じでもよいし、距離Ｄ１より大きくてもよい。 Furthermore, in the storage battery 2 with a packaging box shown in FIG. 6, the fold line 145C of the packaging box side wall 141 is provided at a position below the lower surface of the convex portion 20A in the vertical direction. In this case, the side wall flap 145 rotates by more than 90 degrees and tilts upward toward the inside of the packaging box 40. The flap length L2 may be the same as the distance D1 or may be larger than the distance D1.
　図５、図６に示すように、側壁フラップ４５が水平又は内側に向かって上方に傾斜していると、作業者が梱包箱４０の外側から指先を挿入して梱包箱４０を持ち上げる場合に、指先が梱包箱４０の外側に向かって滑りにくくなる。これにより、梱包箱付き蓄電池１の持ち易さがさらに向上する。 As shown in FIGS. 5 and 6, when the side wall flaps 45 are horizontal or inclined upward toward the inside, when an operator inserts his or her fingertips from the outside of the packaging box 40 and lifts the packaging box 40, The fingertips become less likely to slip toward the outside of the packaging box 40. This further improves the ease of holding the storage battery 1 with packaging box.
　梱包箱付き蓄電池１の構成によると、側壁フラップ４５は、梱包箱４０の内部に折り曲げた状態において、先端４５Ｂが、電槽側壁２０に接触する。 According to the configuration of the storage battery with packaging box 1, the tip 45B of the side wall flap 45 comes into contact with the battery case side wall 20 when the side wall flap 45 is bent into the packaging box 40.
　側壁フラップ４５の先端４５Ｂが、電槽側壁２０に接触しない場合、つまり、側壁フラップ４５のフラップ長Ｌ１が、電槽側壁２０と梱包箱側壁４１の距離Ｄ１よりも小さい場合であっても、側壁フラップ４５の一部が凸部２０Ａの下面に当接することにより、梱包箱付き蓄電池１の荷重を側壁フラップ４５で受けることが可能となるので、持ち易さは向上する。しかしながら、側壁フラップ４５が凸部２０Ａを乗り越える可能性があり、この場合は鉛蓄電池１０の荷重を側壁フラップ４５で受けられず、梱包箱４０を安定して持ち上げることができなくなるおそれがある。これに対し、先端４５Ｂが電槽側壁２０に接触している場合は、側壁フラップ４５が凸部２０Ａを乗り越えにくく、鉛蓄電池１０の荷重を側壁フラップ４５で確実に受けることができる。これにより、鉛蓄電池１０を梱包した梱包箱４０を、より安定して持ち上げることができる。 Even if the tip 45B of the side wall flap 45 does not contact the battery case side wall 20, that is, even if the flap length L1 of the side wall flap 45 is smaller than the distance D1 between the battery case side wall 20 and the packaging box side wall 41, the side wall Since a part of the flap 45 comes into contact with the lower surface of the convex portion 20A, the load of the storage battery 1 with a packing box can be received by the side wall flap 45, and thus the ease of holding is improved. However, there is a possibility that the side wall flap 45 may climb over the convex portion 20A, and in this case, the load of the lead acid battery 10 cannot be received by the side wall flap 45, and there is a possibility that the packaging box 40 cannot be lifted stably. On the other hand, when the tip 45B is in contact with the battery case side wall 20, the side wall flap 45 is difficult to climb over the convex portion 20A, and the load of the lead acid battery 10 can be reliably received by the side wall flap 45. Thereby, the packaging box 40 in which the lead-acid battery 10 is packed can be lifted more stably.
＜実施形態２＞
　図７を参照して、実施形態２に係る梱包箱付き蓄電池３について説明する。実施形態２において実施形態１と実質的に同一の構成要素には、同一の符号を付して説明を省略する。 <Embodiment 2>
A packaging box-attached storage battery 3 according to embodiment 2 will be described with reference to Fig. 7. In embodiment 2, components that are substantially the same as those in embodiment 1 will be denoted by the same reference numerals, and description thereof will be omitted.
　図７に、梱包箱付き蓄電池３を示す。側壁フラップ３４５の、基端３４５Ａから先端３４５Ｂまでのフラップ長Ｌ３は、梱包箱側壁３４１から電槽側壁２０までの距離Ｄ１よりも大きい。 FIG. 7 shows the storage battery 3 with a packaging box. A flap length L3 from the base end 345A to the tip 345B of the side wall flap 345 is greater than the distance D1 from the packaging box side wall 341 to the battery case side wall 20.
　側壁フラップ３４５は、基端３４５Ａで内側に折れ曲がっていることに加え、基端３４５Ａと先端３４５Ｂの中間点３４５Ｅにおいて下方に向かって折れ曲がっている。側壁フラップ３４５は、基端３４５Ａと、中間点３４５Ｅの２箇所で逆方向に９０°ずつ折れ曲がっており、クランク形状になっている。 In addition to being bent inward at the base end 345A, the side wall flap 345 is also bent downward at the midpoint 345E between the base end 345A and the tip 345B. The side wall flap 345 is bent at 90° in opposite directions at two points, a base end 345A and a middle point 345E, and has a crank shape.
　側壁フラップ３４５は、中間点３４５Ｅにおいて凸部２０Ａの下面と電槽側壁２０の両方に接触している。側壁フラップ３４５は、中間点３４５Ｅから先端３４５Ｂにかけて、電槽側壁２０に接触しながら下方に延びている。そのため、側壁フラップ３４５を、基端３４５Ａから中間点３４５Ｅまでの部分が凸部２０Ａの下面に接触した状態よりさらに内側に回動させようとしても、中間点３４５Ｅから先端３４５Ｂにかけての部分が凸部２０Ａの下面で引っ掛かり、回動しにくい。これにより、側壁フラップ３４５が凸部２０Ａを乗り越えて、凸部２０Ａと梱包箱側壁４１の間まで回動することが妨げられる。そして、側壁フラップ３４５を凸部２０Ａの下面に接触させて、側壁フラップ３４５で鉛蓄電池１０の荷重を、より確実に受けることができる。その結果、梱包箱付き蓄電池３を、さらに安定して持ち上げることができる。 The side wall flap 345 is in contact with both the lower surface of the convex portion 20A and the battery case side wall 20 at the intermediate point 345E. The side wall flap 345 extends downward from the intermediate point 345E to the tip 345B while contacting the battery case side wall 20. Therefore, even if an attempt is made to rotate the side wall flap 345 further inward from the state in which the portion from the base end 345A to the intermediate point 345E contacts the lower surface of the convex portion 20A, the portion from the intermediate point 345E to the tip 345B becomes the convex portion. It gets caught on the bottom surface of 20A and is difficult to rotate. This prevents the side wall flap 345 from climbing over the convex portion 20A and rotating between the convex portion 20A and the packaging box side wall 41. By bringing the side wall flap 345 into contact with the lower surface of the convex portion 20A, the load of the lead acid battery 10 can be more reliably received by the side wall flap 345. As a result, the storage battery 3 with packaging box can be lifted more stably.
＜実施形態３＞
　図８を参照して、実施形態３に係る梱包箱付き蓄電池４について説明する。実施形態３において実施形態１と同一の構成要素には、同一の符号を付して説明を省略する。 <Embodiment 3>
With reference to FIG. 8, a storage battery 4 with a packaging box according to a third embodiment will be described. In Embodiment 3, the same components as in Embodiment 1 are given the same reference numerals and explanations are omitted.
　図８に、梱包箱付き蓄電池４を示す。側壁フラップ４４５の、基端４４５Ａから先端４４５Ｂまでのフラップ長Ｌ４は、梱包箱側壁４４１から電槽側壁２０までの距離Ｄ１よりも大きい。側壁フラップ４４５は、基端４４５Ａで内側に９０°折れ曲がっているだけでなく、基端４４５Ａと先端４４５Ｂの中間点４４５Ｅにおいて、下方外側に向かって折れ曲がっている。 FIG. 8 shows the storage battery 4 with a packaging box. A flap length L4 from the base end 445A to the tip 445B of the side wall flap 445 is greater than the distance D1 from the packaging box side wall 441 to the battery case side wall 20. The side wall flap 445 not only bends inward at 90° at the base end 445A, but also bends downward and outward at the midpoint 445E between the base end 445A and the distal end 445B.
　側壁フラップ４４５は、中間点４４５Ｅにおいて凸部２０Ａの下面と電槽側壁２０の両方に接触している。側壁フラップ４４５は、中間点４４５Ｅから先端４４５Ｂにかけて、電槽側壁２０に接触せずに下方外側に向かって延びている。 The side wall flap 445 is in contact with both the lower surface of the convex portion 20A and the battery case side wall 20 at the intermediate point 445E. The side wall flap 445 extends downward and outward from the intermediate point 445E to the tip 445B without contacting the battery case side wall 20.
　ＥＮ規格の蓄電池は、電槽底壁２２に、平面視にて凸部２０Ａよりも外側に突出した固定部２９を有している。図８の構成では、側壁フラップ４４５は、中間点４４５Ｅから先端４４５Ｂにかけて、下方外側に向かって延びている。このような構成では、梱包箱４０内の鉛蓄電池１０を鉛直上方に取り出す際に、固定部２９が下方から側壁フラップ４４５に接触しても、側壁フラップ４４５が折り畳まれるように変形する。そして、折り畳まれた側壁フラップ４４５が押しのけられて、鉛蓄電池１０を取り出すことができる。これにより、側壁フラップ４４５が固定部２９に引っ掛かりにくくなり、鉛蓄電池１０の取り出しが容易になる。 The EN standard storage battery has a fixing part 29 on the bottom wall 22 of the battery case that protrudes outward from the convex part 20A in plan view. In the configuration of FIG. 8, sidewall flap 445 extends downwardly and outwardly from midpoint 445E to tip 445B. In such a configuration, even when the fixing portion 29 contacts the side wall flap 445 from below when the lead acid battery 10 inside the packaging box 40 is taken out vertically upward, the side wall flap 445 is deformed so as to be folded. The folded side wall flap 445 is then pushed away and the lead acid battery 10 can be taken out. This makes it difficult for the side wall flap 445 to get caught on the fixing portion 29, making it easier to take out the lead acid battery 10.
＜実施形態４＞
　図９を参照して、実施形態４に係る梱包箱付き蓄電池５について説明する。実施形態４において実施形態１と同一の構成要素には、同一の符号を付して説明を省略する。 <Embodiment 4>
With reference to FIG. 9, a storage battery 5 with a packaging box according to a fourth embodiment will be described. In Embodiment 4, the same components as in Embodiment 1 are given the same reference numerals and explanations are omitted.
　梱包箱付き蓄電池５の梱包箱５４０では、側壁フラップ５４５のフラップ長Ｌ５が、電槽側壁２０と梱包箱側壁５４１との距離Ｄ１よりも大きい。また、側壁フラップ５４５は、基端５４５Ａで折れ曲がり、水平になっている。先端５４５Ｂが、凸部２０Ａの下面に接触している。 In the packaging box 540 of the storage battery 5 with packaging box, the flap length L5 of the side wall flap 545 is larger than the distance D1 between the battery case side wall 20 and the packaging box side wall 541. Further, the side wall flap 545 is bent at the base end 545A and is horizontal. The tip 545B is in contact with the lower surface of the convex portion 20A.
　フラップ長Ｌ５が、距離Ｄ１よりも大きいため、側壁フラップ５４５を折り曲げて先端５４５Ｂが電槽側壁２０に当接して水平になると、梱包箱側壁５４１が外側に撓んで弾性変形する。このとき、梱包箱側壁５４１の復元力Ｆにより、先端５４５Ｂが電槽側壁２０に押し付けられる。これにより、側壁フラップ５４５が凸部２０Ａを乗り越えて上方に折れ曲がることが抑制される。作業者は、鉛蓄電池１０の荷重を、凸部２０Ａを介して側壁フラップ５４５で受けることができるため、梱包箱付き蓄電池５を安定して持ち上げることができる。 Since the flap length L5 is larger than the distance D1, when the side wall flap 545 is bent and the tip 545B comes into contact with the battery case side wall 20 and becomes horizontal, the packaging box side wall 541 bends outward and is elastically deformed. At this time, the tip 545B is pressed against the battery case side wall 20 by the restoring force F of the packaging box side wall 541. This prevents the side wall flap 545 from climbing over the convex portion 20A and bending upward. Since the worker can receive the load of the lead-acid battery 10 on the side wall flap 545 via the convex portion 20A, the worker can stably lift the storage battery 5 with a packaging box.
