Abstract
【解決手段】 医療用容器1において、口元部3の表面に合成樹脂フィルム5を熱溶着により溶着し、口元部3の開口部4をシールする医療用容器の密閉方法を採用する。他に、超音波振動、高周波誘電加熱、レーザーによっても合成樹脂フィルム5を溶着することができる。また、開封においては、熱風、輻射熱、レーザー、高周波誘電加熱、電磁誘導、切欠、剥離により、合成樹脂フィルム5を溶解収縮し、開封する方法を採用する。

本発明においては、口元部3の表面に合成樹脂フィルムを溶着し、開口部4を該合成樹脂フィルムでシールし、医療用容器1を密閉する方法を採用する。溶着方法は、熱、超音波、高周波誘電、レーザーのいずれによる溶着方法でも可能である。以下、それぞれの方法について説明する。なお、合成樹脂フィルムの材質は、口元部3と同質の材料であることが好ましく、ポリプロピレン又はポリエチレンが好適である。
発熱体10の突条10aがフィルム5に当接し、フィルム5が溶解し始める。次に、フランジ3aも溶解し、フィルム5とフランジ3aとが溶着される。溶着終了後、フィルム5を適当に切断すれば、密封が完了する。なお、巻き取り装置12とローラ13とを備えていれば、フィルム5を順次供給できるので、フィルム溶着の効率が向上する。また、発熱体10は、電気ヒーター等により加熱することができる。なお、刃部15を設けて、溶着完了後、刃部15を下方に移動させてフィルム5を切断することも可能である。
超音波振動子20が振動しながら下方に移動すると、突条20aがフィルム5に当接し、フィルム5が加圧されながら振動される。フィルム5とフランジ3aとの間に摩擦が生じ、摩擦熱が発生する。該摩擦熱によりフィルム5とフランジ3aが溶解することにより、溶着される。
