Abstract
Description
(1)空気は通すが水(液体)は通さないこと
(2)大気導入弁と同様の役割が必要であることから、通気性は少ないほうが良い。ただし、全く空気を通さないと、外層11と内層12の間に空気が入らないので、不適である。また、通気性のバランスも考慮する必要がある。
(3)超音波溶着による取り付けを行う場合、超音波溶着で適する材質であること(超音波溶着の際に微細粉が発生しないこと)
これら要件を満たす疎水性フィルタFを用いることにより、スクイズ時の内圧維持と、復元時の外気導入をコントロールすることが可能である。

Claims (5)
- 外殻と内袋とを有し、内袋に収容される内容物の減少に伴って前記内袋が収縮する二重容器であって、
前記外殻には空気導入孔が形成されるとともに、空気を透過し水を遮断する疎水性フィルタが前記空気導入孔を塞ぐように設けられていることを特徴とする二重容器。 - 前記疎水性フィルタは、ポリプロピレンの不織布により形成されていることを特徴とする請求項1記載の二重容器。
