Description
請求項1に記載の発明によれば、谷折りされた前記封止部は、前記注出部以外の部分全体にわたってそれぞれ密着させて接着されたことにより、注出部と封止部との接合部分周辺に気泡が形成されることや、この気泡中の空気が収容室内部に漏れ出す事態を防止できる。これにより、収容室内部に収容された流動体の変質を一層確実に防止できる。
まず、図4に示す通り、一対の第一のシート6,6を、それぞれの融着性樹脂フィルム8が対向するように配置させる。
次に、図5に示す通り、第二のシート7によって形成された封止部4を長手方向略中央部で谷折りし、谷折りにされた封止部4の間に注出部2の固定部14を保持させる。容器本体1の注出部2の筒状部13には、キャップ17が螺合されても良い。
次に、第一の工程で対向された一対の第一のシート6,6の一端部側に前記第二の工程で得られた封止部4及び注出部2を配設し、対向する第一のシート6,6同士、及び、第一のシート6と封止部4とが接触した状態とする。この状態で、図6の(a)に示す通り、対向する第一のシート同士6,6の両側の周縁部18,18と、封止部4と第一のシート6の一端部とをそれぞれヒートプレス(図示せず)等によって加熱・加圧する。これにより、融着性樹脂フィルム8が融解したのちに固化し、加熱・加圧した箇所は熱融着される。これにより、収容室5が形成されるが、この段階では第一のシート6,6の基端側は熱融着されていない。
