Description

【発明の詳細な説明】 本発明は、電槽と蓋とを熱溶着してなる蓄電池とその製
造法の改良に関するものである。
従来、この種の蓄電池においては、第５図に示す如く電
槽（図示省略）の上端面に対応して蓋Ａの下面に溶着代
としての突条Ｂを設けている。
しかしながら此の構造では成型上並びに組立上、必然的
に生じる電槽隔壁等の反りを考慮して、突条Ｂの巾を電
槽隔壁等の巾よりも広く設定しているため、蓋の肉厚が
部分的に不均等になってヒケＣを生じる欠点があった。
また電槽隔壁等と蓋下面の突条Ｂとを正しく衝合させる
ための手段として、第６図に示す如くカイトＤを設けた
蓋Ａ′も提案されているか、これによっても常に万全で
あるとは言えず、いずれにしても電槽と蓋とを完全に熱
溶着するためには組立上かなりの手数を要する欠点があ

本発明は、上記の欠点を一挙に解消せんとするものであ

次に、図示した本発明蓄電池の製造法について説明する

引続いて熱板７を除去し、電槽１と蓋４とを相互に圧着
すれば、第１図及び第２図に示す如く前記両者を液密に
シールする熱溶着部６の形成された蓄電池が得られる。

本発明は、叙上の通り電槽１の上端面と被溶着部の突出

挿入した状態において電槽１の隔壁２や周壁ろが反って
いても、電槽１の上端面に対応して溶融される蓋下面５
