Description
く、フランジ部に沿って縦方向に剥離することにより開封が容易であり、またパック容器を取り扱う製造業者、豆腐などの商品をパックする業者、パック容器入り商品を運搬する業者及び販売する業者、或いは末端の消費者に、開封の不安、例えば製造、流通過程で誤って開封してしまうのではないかという不安や、商品を手にした消費者が、途中で開封されているのではないかという不安を抱かせることがないという効果を奏する。
は、円型リング状の剥離用フィルム36に等間隔で3個の内向きの剥離開始部51を傾斜状に設けた例を示す。
型、図28、丸型、図29)、成形され破断部を形成されたパック容器11が進むにつれ剥離用フィルム16がパック容器11にはまり込むようにし、さらに熱ヒーターによって成形品と剥離用フィルム16が一体化した後、打ち抜き機によって成形シートと剥離用フィルム16を一緒に打ち抜くことによって、大量に安く作ることができる。54は切断予定線を示す。ただし、フランジ部12の外側に剥離開始部21、41があると、パック容器11の打ち抜きと剥離用フィルム16の打ち抜きで寸法が異なるため技術的に大変難しくなる。ところが内側の剥離開始部31、51の場合には打ち抜き寸法が同じなので、簡単であるばかりでなく、打ち抜き型等変更の必要がないためさらに安く製造できる利点がある。
