PROBLEM TO BE SOLVED: To provide a double inner stopper for a medical fluid container which prevents a medical fluid in the medical fluid container from scattering in a cap when the cap is removed and has no possibility of generating deterioration of the medical fluid.SOLUTION: An inner cylinder 11 and an outer cylinder 12 respectively integrally molded are combined coaxially vertically, and are inserted into an opening part K1 of the medical fluid container K, and the lower end part of a blocking pin 12b of the outer cylinder 12 is inserted into a tapered hole 11b of the bottom part of the inner cylinder 11 constituting the double inner stopper 10 of the medical fluid container K. A small channel for a flow path of the medical fluid communicating with a spouting hole 11a from the inside of the medical fluid container K is formed in either one of the inner face of the tapered hole 11b or the outer face of the lower end part of the blocking pin 12b.COPYRIGHT: (C)2010,JPO&INPIT【課題】キャップを外す際などにおいて、薬液容器内の薬液がキャップ内に飛散することを防止し、かつ薬液の変質のおそれがない薬液容器の二重中栓を提供する。【解決手段】それぞれが一体成型された内筒11と外筒12を上下に同軸状に組み合わせて薬液容器Kの口部K1に挿着し、該薬液容器Kの二重中栓10を構成する内筒11の底部のテーパ孔11bに外筒12の閉塞ピン12bの下端部を挿入し、テーパ孔11bの内面、閉塞ピン12bの下端部の外面のいづれか一方に薬液容器Kの内部から注出孔11aに連通する薬液の流路用の小溝を形成する。【選択図】図1
