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リ・・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つ
てヒケ・・Ｃを生じる欠点があつた。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図に示す如くガイドＤを設けた蓋
A′も提案されているが、これによつても常に万
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
を要する欠点があつた。
本発明は、上記の欠点を一挙に解消せんとする
ものであり、以下これを一実施例に基づいて説明
する。
まず図において１はポリオレフイン系合成樹脂
例えばポリプロピレン或はポリエチレンで成型さ
れた電槽、２，３はそれぞれ電槽１の隔壁及び周
壁、４は電槽１と同等材料からなる蓋、５は従来
の突条Ｂ（第５図及び第６図参照）の様な突出し
た被溶着部を有していない蓋下面、６は融合して
一体となつた熱溶着部、７は熱板、８は電槽１の
上端面（換言すれば隔壁２及び周壁３の上端面）
に対応して熱板７の上面に付設されたリブ、９は
蓋４を吸引して保持するための吸着盤である。な
お図中１０は極板群、１１，１２はそれぞれ注液
口及び端子孔、１３は端子を示す。
次に、図示した本発明蓄電池の製造法について
説明すると、まず常法により極板群１０を組成
し、これを電槽１に挿入すると共にセル間を接続
した後、第３図に示す如く熱板７を介在させて電
槽１の上端面と蓋下面５とを溶融する。このと
き、第４図に示す如く平坦であつた蓋下面５の被
溶着部は、熱板７のリブ８によつて溝状に溶融さ
れる。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。
なお熱板リブ８の巾は３〜10mmが適当であり、
この様なリブ８を有する熱板７を用いて熱溶着に
適した１〜1.5mmの深さまで溶融する場合、蓋４
の厚さは２mm以上とするのが望ましい。
本発明は、叙上の通り電槽１の上端面と被溶着
部の突出していない蓋下面５とを熱溶着するの
で、極板群１０を挿入した状態において電槽１の
隔壁２や周壁３が反つていても、電槽１の上端面
に対応して溶融される蓋下面５の溶融巾が電槽隔
壁等の反リ・・の大きさに見合つた寸法となる様に、
熱板リブ８の巾を適宜寸法に設定しておくことに
より、電槽１と蓋４とを確実且つ簡単に溶着する
ことができる。しかも蓋下面５には従来の様な突
条Ｂを全く設けないので、蓋４は実質的に平板上
の単純な形となり、従つて肉厚の不均等による
ヒケ・・がなく外観的にも良好で且つ蓋４のコストも
従来品に比し安価となる利点を有する。
上記の利点を有する本発明は、熱溶着により電
槽と蓋とを接合するタイプの各種蓄電池に適用可
能であるが、多量生産される自動車用蓄電池等に
は取分け好適である。
【図面の簡単な説明】
第１図は本発明蓄電池の要部破断側面図、第２
図は同蓄電池の要部拡大断面図、第３図は電槽と
蓋を熱板で加熱溶融している状態を示す要部破断
側面図、第４図は蓋の斜視図、第５図及び第６図
は従来の蓋の各例を示す部分断面図である。 １……電槽、４……蓋、５……蓋下面、６……
熱溶着部、７……熱板、８……リブ。
