Claims (14)
- 刳り抜き本体を有するインサートと;圧出オリフィスを通って開通する中央流路が貫通している前記本体の延長線上にある分配用ノズルと;前記ノズルの基部に前記インサートを横断して取付けられ、分配方向での液体の通過および液体分配後にその補償として流入を促される空気のその逆方向での通過を可能にするための、部分的に親水性で部分的に疎水性である抗菌性の濾過膜とを有する、液体分配用滴下ヘッドであって、前記インサートが、前記膜の方向へと多孔質パッドを横断する液体流を調節する多孔質パッドを含んでいる、滴下ヘッドであり、インサート(4)は、中央ペレット(11)を支持する複数の長手方向アーチ(13)を形成する基部によって、分配用ノズルの反対側で前記パッドを超えて終結しており、分配用ヘッドの出口で補償のために流入する空気のラジアル方向の流れのために開放された複数の通路をアーチ相互間に構成していることを特徴とする、液体分配用滴下ヘッド。
- アーチ(13)はその数が三つであり、ボトルの頸部の軸を中心として互いに角度的に等距離で配置されていることを特徴とする、請求項1に記載の分配用ヘッド。
- 前記中央ペレットが、インサートの出口での直接的な軸方向噴射を妨げながら、分配用ヘッドから進入する空気をその中央ペレットの周囲に通過させるための開放空間を残すような形で、インサートの軸内に心出しされていることを特徴とする、請求項1または2に記載の分配用ヘッド。
- アーチ(13)の高さが1〜5mm、好ましくは2〜4mmであることを特徴とする、請求項1〜3のいずれか一つに記載の分配用ヘッド。
- 多孔質パッドが、20〜120μm相当の孔径を有するフェルトの形状をした疎水性材料でできた微多孔質パッドであることを特徴とする、請求項1〜4のいずれか一つに記載の分配用ヘッド。
- 多孔質パッド(8)の上面と膜(7)との間の距離が2mm超、好ましくは約3mm以上であることを特徴とする、請求項1〜5のいずれか一つに記載の分配用ヘッド。

- 請求項1〜9のいずれか一つに記載の分配用ヘッドを介して貯室内部に空気を取込むことにより可逆的に弾性変形する壁を有する貯室を含む、液体分配用滴下ボトルであって、液体が、前記壁に対し加えられた圧力の作用下で前記分配用ヘッドを通って送出され、前記分配用ヘッドが、前記貯室と連通した状態でボトルの頸部にインサートを介して気密的に取付けられており、かつ、部分的に親水性で部分的に疎水性である抗菌性の濾過膜が、前記ノズルの基部に前記インサートを横断して取付けられており、分配方向での液体の通過および液体の分配後にボトル内に補償として流入を促される空気のその逆方向での通過を可能にしている液体分配用滴下ボトルであって、インサート(4)の基部が、前記貯室の内部で終結し、複数のアーチによって構成された複数の通路が、前記パッドを横断した後にボトル内に進入する空気のために、貯室の周囲に向かうラジアル方向の流れのために開放されていることを特徴とする、液体分配用ボトル。
- インサート(4)が、中央ペレットの妨害によりボトルの周囲壁に向かってラジアル方向に導かれる進入空気が前記壁に沿って層流状態で誘導されるように、ボトルの周囲壁のくびれ部分(20)の部位にインサートの基部が延在する状態で、ボトルの頸部(10)に取付けられることを特徴とする、請求項10に記載のボトル。
- インサート(4)が、ボトルの頸部(10)の内部に押し込み嵌合されることでボトル内に組立てられること、およびその上縁部に、ボトルの頸部(10)の上縁部によって支持される、より大きい直径の冠状部(14)を有し、こうして前記頸部(10)内に前記インサート(4)が正しく位置づけされるようになっていることを特徴とする、請求項10または11のいずれか一つに記載のボトル。
- 中央ペレット(11)が、ボトルの軸内に心出しされ、こうしてインサートの出口での直接的な軸方向噴射を妨げながら、ボトルの周囲壁に向かってラジアル方向に空気が通過するための開放空間を残すようになっていることを特徴とする、請求項10〜12のいずれか一つに記載のボトル。
- 界面活性特性を有する化合物を含む液体、詳細には目薬の包装に使用されることを特徴とする、請求項1〜13のいずれか一つに記載のボトル。
