また、加熱溶融法の場合、内容物の注入の際に
充填口の内面に内容物が付着すると溶着不能とな

そこで、本発明は、斯様な欠点のないそして簡
単な充填口シール方法を提供しようとするもので

以下、第３図乃至第６図に示す実施例について
説明する。
第３図は、第１例であり、図において、Ｉ〜
は、第１行程乃至第４行程を示している。
第１行程Ｉは、倒立させて内容物Ｂを充填した
合成樹脂製の押出しチユーブＡにおいて、充填口
Ｃを、該口のやや下方でクランプ１１により挾持
して仮閉じすると共に、クランプ上へ突出させ
る。
第２行程は、クランプ上に突出する上記充填
口Ｃを、ヒーター１２で加熱して外面を溶融状態
にする。
第３行程は、外面が溶融状態の上記充填口Ｃ
に、断面コ字状の合成樹脂製シール材Ｅを嵌合さ

より造つておく。
第４行程は、嵌合した上記シール材Ｅを、左
右から他のクランプ１３で挾んで加圧し、シール
材Ｅを充填口Ｃの外側と接合させ、充填口を閉塞
する。
なお、第２行程では、充填口Ｃを加熱したが、
これに代えてシール材を加熱してもよい。
第４図は、第２例であり、図において、Ｉ〜
は、第１行程乃至第３行程を示している。
第１行程Ｉは、第１例と同様で、倒立させて内
容物Ｂを充填した合成樹脂製の押出しチユーブＡ
において、充填口Ｃを、該口のやや下方でクラン
プ１１により挾持して仮閉じすると共に、クラン

第２行程は、クランプ上に突出すると上記充
填口Ｃに、断面コ字状の合成樹脂製のシール材Ｅ
を嵌合させる。
第３行程は、嵌合した上記シール材Ｅを、左
右からホーン１４とアンビル１５とで挾んでホー
ンから超音波振動を与え、シール材Ｅと充填口Ｃ
の外側との接合面相互間に発熱を生じさせて、い

に、クランプ上へ突出させる。
第２行程は、クランプ上に突出する上記充填
口Ｃに、第２例と同様に、断面コ字状の合成樹脂
製のシール材Ｅを嵌合させる。
第３行程は、嵌合した上記シール材Ｅを、高

高周波電流を供給し、該高周波電流により充填口
Ｃ部分のアルミシートａに起電力を生じさせて発
熱を得、つまり、高周波誘導加熱を得て、これに
より充填口Ｃの外側とシール材Ｅとを溶着させ、
充填口Ｃを閉塞する。
本発明によれば、閉じた充填口の外側にシール
材を嵌合させるから、充填口が十分に閉じた状態
でそして該充填口が外からしつかりと包み込まれ
