Description

【０００１】
【発明の属する技術分野】
この発明は、上方にフック部を備えて乾電池を収納した状態でつり下げ可能な電池パッケージに関する。
【０００２】
【発明の背景】
乾電池がつり下げ可能なパッケージに収納された状態で店頭販売されているのをよく見かける。この電池パッケージは、厚紙でできた後面シートと、透明な覆い（ブリスター）が形成された前面プラスチックシートとを貼り合わせた形態で、上方に双方のシートを貫通する開口によってつり下げ用のフック部が形成されている。電池はブリスター内に収納される。複数本の電池であれば、並列に１列に並べられた状態で収納される。また、後面シートにはミシン目が画成されており、ブリスター内の電池を取り出す際には、このミシン目を押し破ったのち、そのミシン目の破断部分を今度は手前に引き裂いてパッケージの後面を広く開封する。
【０００３】
しかし、このブリスター型電池パッケージは、紙シートとプラスチックシートとが貼着されているため、双方を完全に分離することが難しい。そのため、ゴミの分別回収が一般常識となった現在においては、このタイプのパッケージは疎まれる傾向にある。製造者としても、環境に優しい電池パッケージへの転換は、社会的な信用を維持するためにも火急の課題となっている。
【０００４】
また環境問題からの要求に加え、自動化工程によってブリスター型電池パッケージを製造するよりも、人件費の安い海外に生産拠点をシフトさせて人手によって電池パッケージを組み立てた方がコストダウンが図れるという現状からも電池パッケージの形態転換が求められている。
【０００５】
【発明の開示】
上述した電池パッケージに対する形態転換の必要性を考えると、今後は、単一の素材による人の手で組み立てが可能な店頭ディスプレイ用電池パッケージが主流となることは間違いない。そこで本発明者らは、これからの電池パッケージに求められる仕様や特徴について考察した。そして、輸送時には開封され難く、電池を取り出すときに容易に開封でき、かつ、組み立てが容易な構造や形状を備えていることが理想的であるという結論に想到した。また、外部からの衝撃が内部の電池に伝わり難く、複雑な工程を経なくても高い精度で組み立てることができる構造や形状とすることも必要であると考えた。収納電池を素早く取り出せる開封機構もあれば、より好ましいとも考えた。
したがって、本発明は上記考察に基づきなされたもので、その目的は理想的な店頭ディスプレイ用電池パッケージを提供することにある。
【０００６】
上記目的を達成するための第１の発明は、上方にフック部を備えて乾電池を収納した状態でつり下げ可能な電池用パッケージであって、略矩形状の前面と後面が上面および下面を介して連結されてなる折り畳み可能な中空角筒を主体として、前面および後面の左右縁辺に連接されたフラップがそれぞれの連接縁辺を折り線として前記角筒内方向へ折り曲げられて左右に２重の側面が形成され、当該２重側面において角筒内に面したフラップの縁辺には係止突片が突設され、外面のフラップの前記折り線上には前記係止突片が挿入される係止口が開口している店頭ディスプレイ用電池パッケージとしている。

【００２０】
【発明の実施の形態】
＝＝＝基本的な構造と特徴＝＝＝
図１は本発明の実施例における店頭ディスプレイ用電池パッケージ（以下、電池パッケージ）の外観図を示している。また、図２（Ａ）（Ｂ）のそれぞれにこのパッケージ１の前面図と右側面図とを示した。この電池パッケージ１は、厚紙でできており、略矩形状の前面２および後面３が上面４および下面５を介して連結されてなる中空角筒を主体とした構造となっている。中空角筒内は電池の収納空間であり、単３型乾電池を上下に４本、並列に並べて収納することができる。上面４の上方には開口１１ａを有する矩形状プレート１１ｂが連接されてフック部１１が形成されている。なお、この電池パッケージ１は、前面２に内部の電池を確認するための窓１０が開口している。
【００２１】
図３に電池パッケージ１の左側面６および右側面７を開いた状態をそれぞれ（Ａ）（Ｂ）の外観図によって示した。中空角筒の左右開口を閉鎖する左右側面６，７は、前面２の左右縁辺２ａ，２ｂに連接されたフラップ６ａ，７ａと後面３の左右縁辺３ａ，３ｂに連接されたフラップ６ｂ，７ｂを各連接縁辺２ａ，２ｂ，３ａ，３ｂで角筒内方向に折り曲げてなる２重側面となっている。後面３に連接されているフラップ６ｂ，７ｂの縁辺６ｃ，７ｃには凸状の舌片（係止突片）８が突設され、前面２とフラップ６ａ，７ａとの連接縁辺２ａ，２ｂ上にはこの係止突片８が挿入される開口（係止口）９が設けられており、係止突片８のあるフラップ６ｂ，７ｂ、係止口のあるフラップ６ａ，７ａをこの順にそれぞれの連接縁辺に沿って折り曲げると、係止突片８と係止口９とが係合して２重側面６，７が形成されて収納空間が閉鎖される。
【００２２】
普通、２重の側面で電池収納空間を閉鎖する構造の電池パッケージは、重ね合わされたフラップを貼着するのが一般的である。しかし、このような構造では輸送中などに側面の貼着部分が剥がれると、パッケージ内部の電池を収納空間に留める力がなくなり電池が容易に外に出てしまう。それに対し、本実施例の構造では、たとえ外側のフラップ６ａ，７ａが開いたとしても、内側のフラップ６ａ，６ｂの係止突片８が係止口９に係合しているので収納空間は閉鎖されたままの状態に維持される。
【００２３】
＝＝＝収納電池の保護構造＝＝＝
さらに電池パッケージ１は、上面４の前後が斜面４ａ，４ｂになっており、これら前後斜面４ａ，４ｂの下縁がそれぞれ前後面２，３の上縁辺２ｃ，３ｃに連接されている。すなわち上面４は山型の屈折面となっている。また、前後の斜面４ａ，４ｂは左右対称の逆台形状であり、これら斜面４ａ，４ｂを分かつ境界線分４ｃにフック部１１が連接されている。下面５は、上面４と同じく前後が斜面５ａ，５ｂとなる谷型の屈折面であり、前後斜面５ａ，５ｂの上縁がそれぞれ前後面２，３の下縁辺２ｄ，３ｄに連接している。また、斜面５ａ，５ｂの形状は左右対称の台形状で、上面４の斜面４ａ，４ｂとは上下に対象な形状となっている。
【００２４】
前面２および後面３に連接されているフラップ６ａ，７ａ，６ｂ，７ｂは、上面４と下面５の前側斜面４ａ，５ａおよび後側斜面４ｂ，５ｂの左右縁辺４ｄ，４ｅ，５ｄ，５ｅにも連接されており、側面６，７の形状に近似する略六角形状となっている。
【００２５】
以上の構造により、前後に扁平な６角筒状の電池の収納空間が形成され、この空間に電池を収納したとき、上面４の山や下面５の谷の部分が空隙となる。また側面６，７の上下端部が左右に張り出すため、収納空間の４隅にも空隙ができる。それによって、内部の電池に大きなダメージを与えるとされる面積の小さな上下左右の面４〜７に加わる外力に対し、これらの空隙が緩衝となって内部の電池を保護することができる。
【００２６】
＝＝＝電池パッケージの組み立て＝＝＝
本実施例の電池パッケージ１は、組み立て易い構造や形状、機能も有している。図４は、電池パッケージ１の起源となる組み立て前の型紙の状態を展開図によって示している。この図において、実線は裁断線を示しており、点線と一点鎖線はそれぞれ谷折り（紙面奥から手前へ）の折り線と山折りの折り線を示している。電池パッケージ１の展開形状は、下面５の前後斜面５ａ，５ｂの境界線分５ｃに対してほぼ対象であり、この対象線５ｃから上には、下面５の前側斜面５ａ・前面２・上面４の前側斜面４ａ・フック部１１の前面プレート１１ｃの順に下から上に連接されており、この一連の連接形状の左右に前面２側のフラップ６ａ，７ａが連接されている。一方、対象線５ｃから下には、下面５の後側斜面５ｂ・後面３・上面４の後側斜面４ｂ・フック部１１の後面プレート１１ｄの順に上から下に連接されており、この連接形状の左右に後面３側のフラップ６ｂ，７ｂが連接されている。
【００２７】
＜組み立て手順＞
図５は、型紙の状態から実際に電池パッケージ１を組み立てるまでの手順図を示している。まず、下面５の前後斜面５ａ，５ｂを分かつ境界線５ｃで型紙を折り返すとともに、フック部１１となる前後のプレート１１ｃ，１１ｄを貼着して上面４の前後斜面４ａ，４ｂを連結し、電池の収納空間が折り畳まれた状態にする（Ａ）。なお、フック部１１の前後のプレート１１ｃ，１１ｄが貼着された折り畳み形態は、上下に長く折れやすい型紙のままの形態とは異なり、別の場所にある後段の組み立て工程の現場に搬送する場合などに、コンパクトで型くずれしにくい理想的な荷姿となる。
【００２８】
次に、この折り畳み形態から、後面３側の左右のフラップ６ｂ，７ｂを折り曲げて係止突片８を前面２側のフラップ６ａ，７ａの係止口９に係合させ（Ｂ）、前面２のフラップ６ａ，７ａを後面３側に折り曲げて側面６，７を形成し、電池パッケージ１を完成させる（Ｃ）。
【００２９】
＜組み立て精度の向上＞
本実施例の電池パッケージ１は、極めて単純な工程だけで組み立てることができる基本構造や形状を備えるとともに、組み立て精度の向上を図ったり、組み立て時に型紙が意図しない形状に変形するのを防止したりするための構造・形状も備えている。例えば、型紙の折り返しの境界線５ｃには切り込み１２が画成されており、折り畳み形態にする際に境界線５ｃを逸脱した線分で折り返されないようにして、組み立て精度を向上させている。
【００３０】
＜組み立て時の変形防止＞
また、係止突片８のある後面側フラップ６ｂ，７ｂの縁辺６ｃ，７ｃは、開いた状態にある前面側フラップ６ａ，７ａの裏面に摺動しつつ係止口９と係合するまで折り曲げられる。そこで、この摺動摩擦を軽減するために、係止突片８のあるフラップ６ｂ，７ｂの縁辺６ｃ，７ｃの角１５が面取されてＲ状に形成されている。それによって、後面側フラップ６ｂ，７ｂを抵抗感無く容易に折り曲げることができるとともに、摩擦によってフラップ６ｂ，７ｂや係止突片８が屈曲したり、型紙が剥離したりすることを防止している。
【００３１】
＜確実な閉鎖機構＞
さらに、電池パッケージ１を組み立てる過程には収納空間に電池を収納する工程が含まれることから、２重側面６，７が確実に収納空間を閉鎖する機構が必要となる。そのためには、フラップ６ａ，６ｂ，７ａ，７ｂが所定の折り曲げ状態と所定の展開状態の２つの状態で固定され、中途半端な中間状態になりにくい「双安定性」を備えていることが望ましい。もちろん、この双安定性は電池を取り出す際にも有効である。
【００３２】
本実施例では、この双安定性を実現するために、係止口９のある前面側フラップ６ａ，７ａにおいて、上面４および下面５の前側斜面４ａ，５ｂと連接する山折り線４ｄ，５ｄ上と、前後面２，３の上縁辺２ａ，３ａと下縁辺２ｂ，３ｂを左右に延長した線分、すなわち側面６，７の上下端が左右に張り出して反る際の谷折り線６ｄ，７ｄ上とに、それぞれ切り込み１３，１４が画成されている。
【００３３】
この切り込み１３，１４は、前面側フラップ６ａ，７ａが展開されているときには、このフラップ６ａ，７ａが折り線に沿って自然に曲がろうとする力に対する抑止力を発生するとともに、その抑止力に抗してフラップ６ａ，７ａを折り曲げる際には積極的に折り線で曲がろうとする力に転換する。そして、折り曲げ状態にある後面側フラップ６ｂ，７ｂを上から押さえつける位置まで折り曲げられると、今度は、展開しようとする力に対して抑止力を発揮する。なお、この切り込み１３，１４は、少なくとも山折り線４ｄ上と谷折り線６ｄ上のいずれか一方にあればよい。もちろん、前面側フラップ６ａ，７ａに加えて係止突片８のある後面側フラップ６ｂ，７ｂにも同様な切り込みを備えさせてもよい。
【００３４】
なおミシン目に代えてジッパーによる開封機構を採用してもよい。このジッパーによる開封機構を備えて電池パッケージの例を図７に示した。後面の左右縁辺の下端から徐々に収束して端部へと連続するようにジッパーが形成されている。
【００３５】
＝＝＝第２の実施例：補助開封機構＝＝＝
上記実施例に示した電池パッケージ１は、側面６，７のフラップ６ａ，６ｂ，７ａ，７ｂを展開するだけでパッケージ１の外装を破ることなく内部の電池を簡単に取り出すことができる。そのため、利用者が電池パッケージ１を電池の携帯ケースとして使用するなど、その後も適宜に利用することができる。その反面、電池パッケージ１に用が無い人にとっては、わざわざフラップ６ａ，６ｂ，７ａ，７ｂを展開しなくても素早く内部の電池が取り出せた方がより便利である。本発明では、電池を素早く取り出すのに便利な補助開封機構も提供している。以下、この補助開封機構を備えた電池パッケージを本発明の第２の実施例として説明する。
【００３６】
図６に本発明の第２の実施例における電池パッケージを後面からの斜視図によって示した。この電池パッケージ１ｂの補助開封機構は、後面３を広く開封して電池を取り出すためのものであり、後面３の左右縁辺３ａ，３ｂの一部２１ａには左右対象のミシン目２１が画成されているとともに、この左右縁辺３ａ，３ｂに沿ったミシン目２１を収束するように屈折させ、その収束部２１ｂの先端にはミシン目２１の継ぎ目が無い端部２１ｃが設けられている。開封時にこの端部２１ｃを手前に引き出し、そのままパッケージ１ｂを引き裂くと、収束部２１ａのミシン目２１が徐々に後面３の左右縁辺２１ａのミシン目２１へと案内し、ミシン目２１を外れてパッケージ１ｂが引き裂かれないようになっている。
【００３７】
またこの第２の実施例では、端部２１ｃは上面４の後側斜面４ｂに画成されており、型紙を折り曲げてこの電池パッケージ１ｂを組み立てると、端部２１ｃが上面４の後側斜面４ｂから切り離されて後面３に沿って延長するように設けられる。そのため、斜面４ｂと端部２１ｃとの間に指を入れることができ、容易に端部２１ｃを摘むことができる。
【００３８】
さらにミシン目２１は、端部２１ｃとは反対側の斜面５ｂの縁辺５ｅに連続しており、ミシン目２１を全て破断すると、端部２１ｃから下面５の後側斜面５ｂまで後面３が大きく開封され、電池がより容易に取り出せるようになっている。
【００３９】
なお、ジッパーによる補助開封機構を採用することもできる。図７にジッパーによる補助開封機構を備えた電池パッケージの外観図を示した。ジッパーが折り線と重なると、組み立て時にジッパーに沿って折れ曲がってしまう可能性があることから、ジッパー２２を後面の左右縁辺３ａ、３ｂの下端近傍から徐々に端部２２ｂへ向けて収束させている。またこの例では、下面５の後斜面５ｂの縁辺５ｅにミシン目２３が画成されており、ジッパー２２がこのミシン目２３に連続している。、
＝＝＝その他の実施例・変更例＝＝＝
上記各実施例に示した電池パッケージは、いずれも４本の乾電池を左右に寝かした状態で上下に並べて収納している。もちろん、収納される電池の数や収納方向はこれに限るものではない。また、２重側面となるフラップの係合突片と係合口の数やそれらの係合位置も適宜に変更可能である。図８に収納される電池の数や方向を変更した電池パッケージを例示した。（Ａ）は上下方向に８本の電池を並列にして収納することができる電池パッケージであり、係止突片と係止口による係合箇所が左右の側面にそれぞれ２つずつ設けられている。また（Ｂ）には２本の電池を左右方向に並列にして収納できる電池パッケージを示した。
なお当然のことではあるが、フック部の形状、前面の確認用窓の形状や有無、電池パッケージの素材などは適宜に変更可能であり、上記実施例に限るものではない。
【００４０】
【発明の効果】
本発明の店頭ディスプレイ用電池パッケージによれば、電池収納空間が係止突片を備えたフラップと係止口を備えたフラップとを重ね合わせて２重側面で閉鎖されているため、輸送時などにパッケージが開封して電池が脱落・破損することがない。また、電池を取り出す際には容易に開封することができる。組み立ても容易で生産コストも抑えることもできる。
【００４１】
単一の素材で製造することができ、リサイクルや廃棄時には分別が不要となる。したがって、環境問題に十分対応することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a battery package that can be hung in a state of having a hook portion on the upper side and housing a dry battery.
[0002]
BACKGROUND OF THE INVENTION
We often see that batteries are sold over-the-counter in packages that can be suspended. This battery package is a form in which a rear sheet made of cardboard and a front plastic sheet formed with a transparent cover (blister) are bonded together, and a hook part for hanging by an opening penetrating both sheets upward. Is formed. The battery is housed in a blister. If there are a plurality of batteries, they are stored in a line in parallel. In addition, the rear sheet has a perforation. When the battery in the blister is taken out, after the perforation is pushed through, the broken part of the perforation is torn forward and the rear surface of the package. Widely open.
[0003]
However, in this blister type battery package, since a paper sheet and a plastic sheet are adhered, it is difficult to completely separate both. For this reason, at the present time when separated collection of garbage has become common sense, this type of package tends to be sparse. As a manufacturer, switching to an environmentally friendly battery package has become an urgent issue in order to maintain social trust.
[0004]
Moreover, in addition to demands from environmental issues, it is possible to reduce costs by shifting the production base to overseas where labor costs are low and assembling the battery package manually rather than manufacturing blister battery packages by automated processes. However, there is a need to change the form of the battery package.
[0005]
DISCLOSURE OF THE INVENTION

FIG. 3 shows the state in which the left side surface 6 and the right side surface 7 of the battery package 1 are opened by the external views of (A) and (B), respectively. The left and right side surfaces 6 and 7 that close the left and right openings of the hollow rectangular tube include flaps 6a and 7a that are connected to the left and right edges 2a and 2b of the front surface 2 and flaps 6b and 7b that are connected to the left and right edges 3a and 3b of the rear surface 3, respectively. Each connecting edge side 2a, 2b, 3a, 3b is a double side surface that is bent inwardly into the square tube. Convex tongues (locking protrusions) 8 project from the edges 6c and 7c of the flaps 6b and 7b connected to the rear surface 3, and on the connecting edges 2a and 2b between the front surface 2 and the flaps 6a and 7a. Are provided with openings (locking ports) 9 into which the locking protrusions 8 are inserted. The flaps 6b and 7b with the locking protrusions 8 and the flaps 6a and 7a with the locking holes are respectively arranged in this order. Are bent along the connecting edge, the engaging protrusion 8 and the engaging port 9 are engaged with each other to form the double side surfaces 6 and 7 and the storage space is closed.
[0022]
In general, a battery package having a structure in which the battery housing space is closed by double side surfaces is generally attached with an overlapped flap. However, in such a structure, if the sticking portion on the side surface is peeled off during transportation, the force that holds the battery in the package in the storage space is lost, and the battery easily goes out. On the other hand, in the structure of the present embodiment, even if the outer flaps 6a and 7a are opened, the engaging projections 8 of the inner flaps 6a and 6b are engaged with the engaging opening 9, so that the storage space is It is kept closed.
[0023]
=== Protective structure of storage battery ===
Further, the battery package 1 has slopes 4a and 4b on the front and back of the upper surface 4, and the lower edges of the front and back slopes 4a and 4b are connected to the upper edges 2c and 3c of the front and rear faces 2 and 3, respectively. That is, the upper surface 4 is a mountain-shaped refracting surface. Further, the front and rear slopes 4a and 4b have symmetrical trapezoidal shapes, and the hook portion 11 is connected to the boundary line segment 4c that separates the slopes 4a and 4b. The lower surface 5 is a valley-shaped refracting surface with the front and rear inclined surfaces 5a and 5b, like the upper surface 4, and the upper edges of the front and rear inclined surfaces 5a and 5b are connected to the lower edges 2d and 3d of the front and rear surfaces 2 and 3, respectively. . In addition, the shapes of the slopes 5a and 5b are symmetrical trapezoidal shapes, and the shapes of the slopes 4a and 4b on the upper surface 4 are the top and bottom.
[0024]
The flaps 6a, 7a, 6b, 7b connected to the front surface 2 and the rear surface 3 are also formed on the front slopes 4a, 5a of the upper surface 4 and the lower surface 5 and the left and right edges 4d, 4e, 5d, 5e of the rear slopes 4b, 5b. It is connected and has a substantially hexagonal shape that approximates the shape of the side surfaces 6 and 7.
[0025]
With the above structure, a storage space for a flat hexagonal cylindrical battery is formed in the front and rear, and when the battery is stored in this space, the crests on the upper surface 4 and the valleys on the lower surface 5 become voids. Moreover, since the upper and lower ends of the side surfaces 6 and 7 project to the left and right, voids are formed at the four corners of the storage space. Accordingly, these gaps can serve as a buffer to protect the internal battery against an external force applied to the upper, lower, left, and right surfaces 4 to 7 having a small area that is supposed to cause great damage to the internal battery.
[0026]
=== Assembling the battery package ===
The battery package 1 of this embodiment also has a structure, shape, and function that are easy to assemble. FIG. 4 is a development view showing the state of the pattern before assembly, which is the origin of the battery package 1. In this figure, the solid line indicates the cutting line, and the dotted line and the alternate long and short dash line indicate the fold line of the valley fold (from the back to the front of the page) and the fold line of the mountain fold, respectively. The unfolded shape of the battery package 1 is substantially the target with respect to the boundary line segment 5c of the front and rear slopes 5a and 5b of the lower surface 5, and the front slope 5a, front surface 2, and upper surface 4 of the lower surface 5 are located above the target line 5c. The front slope 4a and the front plate 11c of the hook portion 11 are connected from the bottom to the top, and the flaps 6a and 7a on the front surface 2 side are connected to the left and right of this series of connection shapes. On the other hand, below the target line 5c, the rear slope 5b of the lower surface 5, the rear face 3, the rear slope 4b of the upper face 4, and the rear plate 11d of the hook portion 11 are connected in order from the top to the bottom. The flaps 6b and 7b on the rear surface 3 side are connected to the right and left of the.
[0027]
<Assembly procedure>
FIG. 5 shows a procedure diagram from the state of the pattern to the actual assembly of the battery package 1. First, the front and rear slopes 5a and 5b of the lower surface 5 are divided, the pattern paper is folded back at the boundary line 5c, and the front and rear plates 11c and 11d to be the hook portions 11 are attached to connect the front and rear slopes 4a and 4b of the upper surface 4 to The storage space is folded (A). Note that the folded form in which the plates 11c and 11d before and after the hook part 11 are attached is different from the form of a pattern that is long and easy to fold, and is transported to a subsequent assembly process site in another place. For example, it is an ideal packaging that is compact and difficult to lose shape.
[0028]
Next, from this folded form, the left and right flaps 6b, 7b on the rear surface 3 side are folded to engage the locking protrusions 8 with the locking openings 9 of the flaps 6a, 7a on the front surface 2 side (B). The flaps 6a and 7a are bent to the rear surface 3 side to form the side surfaces 6 and 7, and the battery package 1 is completed (C).
[0029]
<Improved assembly accuracy>
The battery package 1 of the present embodiment has a basic structure and shape that can be assembled by a very simple process, improves assembly accuracy, and prevents the pattern from being deformed into an unintended shape during assembly. It also has a structure and shape to do this. For example, the notch 12 is defined in the boundary line 5c for folding the paper pattern, and the assembly accuracy is improved so that the folded pattern is not folded at a line segment that deviates from the boundary line 5c.
[0030]
<Preventing deformation during assembly>
Further, the edges 6c and 7c of the rear side flaps 6b and 7b with the locking protrusions 8 are bent until they are engaged with the locking holes 9 while sliding on the back surfaces of the front side flaps 6a and 7a in the open state. It is done. Therefore, in order to reduce this sliding friction, the corners 15 of the edges 6c and 7c of the flaps 6b and 7b with the locking protrusions 8 are chamfered to form an R shape. As a result, the rear side flaps 6b and 7b can be easily bent without a sense of resistance, and the flaps 6b and 7b and the locking protrusion 8 are prevented from being bent or the pattern paper is peeled off due to friction. .
[0031]
<Reliable closing mechanism>
Furthermore, since the process of assembling the battery package 1 includes a step of storing the battery in the storage space, a mechanism for the double side surfaces 6 and 7 to reliably close the storage space is required. For that purpose, it is desirable that the flaps 6a, 6b, 7a, 7b are fixed in two states, a predetermined bent state and a predetermined unfolded state, and have “bistability” that is unlikely to be a halfway intermediate state. . Of course, this bistability is also effective when the battery is taken out.
[0032]
In the present embodiment, in order to realize this bistability, on the front side flaps 6a and 7a having the locking port 9, on the mountain fold lines 4d and 5d connected to the front side inclined surfaces 4a and 5b of the upper surface 4 and the lower surface 5. And a line segment obtained by extending the upper and lower edges 2a, 3a and the lower edges 2b, 3b of the front and rear surfaces 2, 3 to the left and right, that is, the valley fold lines 6d, 7d when the upper and lower ends of the side surfaces 6, 7 project to the left and right. Incisions 13 and 14 are defined above and below, respectively.
[0033]
When the front side flaps 6a and 7a are unfolded, the notches 13 and 14 generate a deterring force against the force that the flaps 6a and 7a naturally bend along the fold line. When the flaps 6a and 7a are bent against this, the force is positively converted to a force to bend at the fold line. And if it is bent to the position which presses back side flaps 6b and 7b in the state of bending from the top, this time, deterrent power will be demonstrated to the force which is going to expand. The cuts 13 and 14 may be at least on one of the mountain fold line 4d and the valley fold line 6d. Of course, in addition to the front side flaps 6a and 7a, the rear side flaps 6b and 7b having the locking protrusions 8 may be provided with similar notches.
[0034]
Note that a zipper opening mechanism may be employed instead of the perforation. FIG. 7 shows an example of a battery package provided with this zipper opening mechanism. A zipper is formed so as to converge gradually from the lower end of the left and right edges of the rear surface and continue to the end.
[0035]
=== Second Example: Auxiliary Opening Mechanism ===
The battery package 1 shown in the above embodiment can be easily taken out without breaking the package 1 by simply unfolding the flaps 6a, 6b, 7a and 7b on the side surfaces 6 and 7. Therefore, the user can use the battery package 1 as appropriate, such as using the battery package 1 as a battery carrying case. On the other hand, it is more convenient for a person who does not use the battery package 1 to quickly take out the internal battery without having to unfold the flaps 6a, 6b, 7a, 7b. The present invention also provides an auxiliary opening mechanism convenient for quickly removing the battery. Hereinafter, a battery package provided with this auxiliary opening mechanism will be described as a second embodiment of the present invention.
[0036]
FIG. 6 is a perspective view of the battery package according to the second embodiment of the present invention from the rear surface. The auxiliary opening mechanism of the battery package 1b is for opening the rear surface 3 wide and taking out the battery, and the left and right perforations 21 are defined on the left and right edges 3a and 3b of the rear surface 3. In addition, the perforation 21 along the left and right edges 3a and 3b is refracted so as to converge, and an end 21c without a seam of the perforation 21 is provided at the tip of the convergence portion 21b. When the end 21c is pulled forward and the package 1b is torn as it is opened, the perforation 21 of the converging portion 21a gradually guides to the perforation 21 on the left and right edges 21a of the rear surface 3, and the perforation 21 is removed from the package. 1b is not torn.
[0037]
In the second embodiment, the end 21c is defined on the rear slope 4b of the upper surface 4. When the battery package 1b is assembled by folding the pattern, the end 21c becomes the rear slope 4b of the upper surface 4. So as to extend along the rear surface 3. Therefore, a finger can be put between the inclined surface 4b and the end 21c, and the end 21c can be easily picked.
[0038]
Further, the perforation 21 is continuous with the edge 5e of the slope 5b opposite to the end 21c, and when the perforation 21 is completely broken, the rear surface 3 is greatly opened from the end 21c to the rear slope 5b of the lower surface 5. Thus, the battery can be taken out more easily.
[0039]
An auxiliary opening mechanism using a zipper can also be employed. FIG. 7 shows an external view of a battery package provided with an auxiliary opening mechanism using a zipper. If the zipper overlaps the fold line, it may be bent along the zipper during assembly, so the zipper 22 is gradually converged from the vicinity of the lower ends of the left and right edges 3a and 3b on the rear surface toward the end 22b. . In this example, a perforation 23 is defined on the edge 5 e of the rear slope 5 b of the lower surface 5, and the zipper 22 is continuous with the perforation 23. ,
