形成して重ね合わせ溶着した筒体の端部に、プラスチッ

する装置に関する。
〔従来の技術〕
例えば歯磨用のクリームなどのクリーム、軟膏状物質の
容器として第７図に示す形状の押出チューブが広く用い
られている。このチューブはプロー成形法によりポリエ
チレン、ポリプロピレン等で一体成形されている。しか
しこれらの材料はガスバリヤ−性が十分ないため封入し
たものが芳香を有するものである場合には、芳香成分が
容器を透過して消失する。また酸素が容器を透過して内
部に侵入し封入物が変質、変色するなどし長期の保存に
耐えない。このためねりわさび１ねり辛子などの容器に

以上の欠点を解消するため、最近では、数十μｍの厚さ

ミニウム表面の保護を目的としてポリエチレンフィルム
又はポリプロピレンフィルムを貼り合わせたラミネート
フィルムを用いたチューブが開発されている。このラミ

返しの曲げに強い。
このラミネートフィルムは、その構造上からプロー成形
法やインジェクション成形法によす直接チューブを形成
することは不可能である。
この素材を用いてチューブを製造するには大別して次の
二通りの方法がある。
第３図に示すように、ラミネートフィルム／を円筒状に
曲げ両端を重ね合わせ、重ね合わせ部を溶着して第９図

筒体コとを一体化する。また別途成形した口部３と筒体
コとを溶着して第１０図に示すように一体化する。前者
の方法では、筒体コを一つ一つ金型に挿入しなければな

ンジェクションマシンの稼動率が下がる。
後者の方法では、フィルムの筒状化と、口部の成形が別
工程で行なわれるため、それぞれの工程を最も能率的な
条件下で生産できる。しかしこの方法で問題となるのは
、別々に成形した口部３と筒体コとの溶着工程である。
これにはヒートシールによる方法と、高周波誘導加熱に
よる方法とがある。ヒートシールによる方法では、シー
ルに時間がかかること、溶着用金型の温度管理が難かし
いことなどから高速で安定した生産には不向きである。
そのため、最近では高周波誘導加熱による方法が注目さ

高周波誘導加熱による方法の原理は、第１１図に示すよ

流れる電流７が生じ、その向きはワークコイルの電流の

〔発明が解決しようとする問題点〕
本発明はラミネートフィルムからなる前記の筒体コの端

部分品を溶着するに当り、口部３内にアルミシートｔの
