25b 内容液保持部材
Claims (7)
- ボトルの口部に設けられた栓体に、ボトル内に収容された内容液を吐出するための吐出路を設け、該吐出路にはフィルターを設け、該フィルターは、吐出方向の下流側から上流側への細菌類の透過を阻止するように細菌類を濾過する濾過膜と、濾過膜の上流側に設けられた多孔質体からなる内容液保持部材とからなり、該内容液保持部材は濾過膜に面接触しており、
ボトルは、スクイズ変形可能な外層ボトルと、該外層から剥離可能に設けられた内層袋とを備え、該内層袋内に前記内容液が収容され、外層ボトルをスクイズ変形させることにより外層ボトルと内層袋との間の空気を加圧可能であり、該加圧空気によって内層袋が圧縮され、これにより内層袋内の内容液が前記内容液保持部材及び濾過膜を通過し、
内層袋は、内部負圧と大気圧との圧力差が濾過膜の濾過抵抗よりも大きくなるように膨張する復元性を有し、該内層袋の復元性によって内層内部に負圧を生じさせ、これにより濾過膜の下流側に残留する残液を濾過膜の上流側に吸引するように構成されていることを特徴とするフィルター付き容器。 - フィルターは、内容液が含浸された状態において下流側から空気を吸い込むための抵抗が、前記内層袋の復元性による内層袋の内部圧力と大気圧との差よりも大きくなるように設けられていることを特徴とする請求項1に記載のフィルター付き容器。
- 濾過膜は、その下流側表面近傍の平均孔径が0.1〜0.5μmでありかつ上流側に至るに従って平均孔径が大きくなるか若しくは同等である多孔質体からなる薄膜であることを特徴とする請求項1又は2記載のフィルター付き容器。
- 内容液保持部材を内容液が上流側から下流側へ通過するための必要圧力は12hPa以下であることを特徴とする請求項1,2又は3記載のフィルター付き容器。
- 内容液保持部材を内容液が上流側から下流側へ通過するための必要圧力は、濾過膜の濾過抵抗よりも小さいことを特徴とする請求項1〜4のいずれか1項に記載のフィルター付き容器。
- 前記濾過膜は、親水性を有することを特徴とする請求項1〜5のいずれか1項に記載のフィルター付き容器。
- 外層ボトルには、外層ボトルと内層袋との間に外気を導入するための導入口が形成されていることを特徴とする請求項1〜6に記載のフィルター付き容器。
