レトルト加熱殺菌を必要とする液体飲料を充填する口部付き袋の製造方法として、予め成形した口部をラミネートフイルムで形成した袋の開口部に挿入し、開口部に挿入し口部をシール部に合わせた形状を持つヒートシールバーを用いて袋の開口部内面に溶着する口部付き袋を作る製造方法は知られている。
【０００３】
この種の口部付き袋は、缶やビンに比較して軽量で開封性がよいので、液体飲料だけでなくうどんのめんつゆや焼き肉のたれの収納容器としてガラス瓶やプラスチック容器に代えて用いることもできる。
【０００４】
【発明が解決しようとする課題】
上記口部付き袋の製造方法は、成形した口部を袋の内面にヒートシールバーを用いて溶着することで口部付き袋を製造するので、口部と袋とのヒートシール部は三次元形状になり、口部をシール部に合わせた形状を持つヒートシールバーで加熱加圧処理しても、口部と袋のヒートシール部にピンホールのようなシール不良が発生し、シール不良の口部付き袋が成形され、しかも、口部付き袋のピンホールのようなシール不良を検査機により検出することが難しい。
本発明は上記した点に鑑みてなされたもので、口部と袋とのヒートシール部にピンホールのようなシール不良が発生しない口部付き袋の製造方法を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明の口部付き袋の製造方法は、ラミネートフイルムで形成した袋の開口部に少なくとも１本の口部成形具を挿入し、口部成形具を含む開口部を口部成形空間を有する金型で囲み、金型の口部成形空間内の前記金型の内側面と前記口部成形具及び前記袋の外側面との間に樹脂を注入し、少なくとも１本の注ぎ口を有する口部を袋の表面に一体成形するレトルト用口部付き袋の製造方法であって、前記ラミネートフイルムは、ポリエチレンフィルムとポリエステルフィルムとアルミホイルとポリエチレンフィルムの順に層設された４層ラミネートフィルム、または無延伸ポリプロピレンフィルムとポリエステルフィルムとアルミホイルと無延伸ポリプロピレンフィルムの順に層設された４層ラミネートフィルムであり、口部は、袋を形成するラミネートフイルムの表面フイルムと同じ樹脂で成形されることを特徴とする。
