Abstract

【課題】包材内に逆止弁を収納することにより包材の取扱いの邪魔になることがなく、また逆止弁が外部に露出していないので非常に衛生的な包材とすることができる逆止弁付き包材を提供する。 【解決手段】プラスチックフィルム製の包材と、該包材の開口部へ溶着した筒状フィルム製の外筒と、該外筒に内装され、上端に真空ポンプのチューブを装着する脱気口を突設した逆止弁用のハウジングと、該ハウジング内において弁口を前記脱気口側に向けて配設された逆止弁と、該逆止弁の開口部に延長チューブで連結されたフィルタ部材とを備え、 別途用意した真空ポンプのチューブを前記外筒内のハウジングの脱気口に装着し、真空ポンプを作動して前記包材内の空気を排出した場合においては、前記逆止弁で外気が包材内に逆流しないようにしたことを特徴とする逆止弁付き包材。
