PROBLEM TO BE SOLVED: To provide a medical container preventing administration of a medical agent with a fracturable portion of a discharge port unfractured and, even when a medical agent discharging needle tube is inserted with the fracturable portion unfractured, preventing damaging of the distal end thereof.SOLUTION: This medical container 1 includes a container body 2, and the discharge port 3 fixed thereto. The discharge port 3 has a medical agent storage part 34, the fracturable portion 31c that closes one end side of the medical agent storage part and is communicated with the interior of the container body by fracture, and an operating portion 31b thereof. The medical agent storage part 34 stores, in the interior thereof, a medical agent outflow preventing member 4 that can accept the distal end 51 of the medical agent discharging needle tube 50 that has entered in the medial agent storage part 34 with the fracturable part unfractured, and that prevents the outflow of the medical agent from the needle tube 50 accepted therein.COPYRIGHT: (C)2013,JPO&INPIT【課題】本発明の目的は、排出ポートの破断可能部な未破断のまま薬剤が投与されることがなく、かつ、破断可能部が未破断の状態にて、薬剤排出用針管が穿刺されても、その先端部に損傷を与えることがない医療用容器を提供する。【解決手段】医療用容器1は、容器本体2とそれに固定された排出ポート3とを備える。排出ポート3は、薬剤収納部34と、薬剤収納部の一端側を閉塞し、かつ、破断により容器本体内と連通とする破断可能部31cおよびその操作部31bを備える。薬剤収納部34内には、破断可能部の未破断時に薬剤収納部34内に侵入した薬剤排出用針管50の先端部51を受け入れ可能、かつ、受け入れた針管50からの薬剤の流出を阻害する薬剤流出阻害部材4が収納されている。【選択図】図3
