Description
図4は、本実施形態における電池缶の底部のコーナー付近の外観の一部を拡大した斜視図である。同図は、図3(B)の部分に対応する部分である。従来の鉢巻状のA線の上方に、略平行に鉢巻状のB線を設ける。このA線及びB線の詳細は、図5で説明する。
図6は、本実施例における破壊強度測定方法を説明するための図である。本実施例では、縦41[mm]、横40[mm]、高さ4.9[mm]のアルミニウム製の電池缶を用いた。同図に示すように、ストロー状の加圧口31の付いた金属性カバー30を電池缶1の上部の開口部に溶接することにより、その電池缶1を密閉する。次に、その密閉された電池缶1に増幅圧縮エア32を加圧口31より注入して、電池缶1の内圧を上昇させ、電池缶1が破壊した時の圧力を測定する。
なお、本発明は上記の実施形態に何ら限定されるものでなく、本発明の目的を変更しない範囲で適宜変更して実施することが可能である。また、実施例ではアルミニウム製の電池缶を用いたが、材質はこれに限定されず、例えば、金、銀、銅、白金、真鍮、鉄、ステンレス、チタン、ニッケル、マグネシウム、セラミック、ガラス等の無機材料またはこれらの組み合わせでもよい。また、材質は、エンジニアプラスチック等の高分子有機材料、またはこれらの組み合わせでもよい。また、電池缶に限定しなくても、内圧がかかり、かつ、スリム化及び軽量化の必要のあるあらゆる成型品に利用することができる。
また、本実施例では、テーパー27に関する実施例について説明したが、曲面28の場合でも同様の効果を得ることができる。
