PROBLEM TO BE SOLVED: To provide a multi-chambered low-cost container that improves the joining strength of a weak sealed part and facilitates drugs to pass the container when administering them.SOLUTION: The multi-chambered container has a diluent liquid chamber 3 provided next to the one end side of a drug chamber 1 across a partitioning weak sealed part 2 as a border, and an empty chamber 5 with an opening part 6 next to the opposite end side of the drug chamber 1 across a drug discharging weak sealed part 4 as a border. A film material 7 is stuck to the drug chamber 1 for improving the joining strength of both the partitioning weak sealed part 2 and the drug discharging weak sealed part 4. The discharging weak sealed part 4 includes a part 8 that especially easily opens for passing the drugs.COPYRIGHT: (C)2008,JPO&INPIT【課題】 弱シール部の接合強度を向上させ、かつ、投与時の開通を容易としたコスト安の複室容器を提供する。【解決手段】 薬剤収容室1の一端側に仕切り用弱シール部2を介して希釈液室3が連設される一方、前記薬剤収容室1の他端側に排出用弱シール部4を介して口部6を有する空室5が連設される複室容器において、薬剤収容室1には、仕切り用弱シール部2及び排出用弱シール部4の接合強度を向上させるためのフィルム材7が貼り付けられ、かつ、排出用弱シール部4には、部分的に開通させやすい易開通部分8が設けられている。【選択図】 図1
