PROBLEM TO BE SOLVED: To provide a mixing container and a manufacturing method of the mixing container capable of easily mixing reagent liquids by a specimen sampling tool in the mixing container in which a plurality of reagent liquids are mixed by inserting the specimen sampling tool.SOLUTION: A mixing container 10 comprises a first container 11 for storing a first liquid and a second container 20 for storing a second liquid while being inserted to the first container 11. The second container 20 comprises: a cylindrical member 21 made of resin having a top opening 22 and a bottom opening 23 and a sealing film 30 made of a weaker material than the cylindrical member 21 for sealing the bottom opening 23. The cylindrical member 21 comprises a bent part 35 which is supported by an inner peripheral surface 21a between the top opening 22 and bottom opening 23, bent by being pressed against a specimen sampling tool inserted from the top opening 22, and breaks through the sealing film 30. The bent part 35 comprises a sharp projection piece 50, which projects toward the sealing film 30 and causes an initial break to the sealing film 30 at the time of bending, on an opposing surface facing the sealing film 30.COPYRIGHT: (C)2015,JPO&INPIT【課題】検体採取具の挿入によって複数の試薬液が混合される混合容器において、検体採取具による試薬液の混合を容易に行うことが可能な混合容器及び混合容器の製造方法を提供する。【解決手段】混合容器10は、第1液を貯留する第1容器11と、第1容器11に挿入された状態で第2液を貯留する第2容器20と、を備える。第2容器20は、頂部開口22と底部開口23とを有する樹脂製の筒状部材21、筒状部材21よりも脆弱な材質で形成され底部開口23を封止する封止膜30と、を備える。筒状部材21は、頂部開口22と底部開口23との間に内周面21aに支持され、頂部開口22から挿入された検体採取具に押圧されることで屈曲し、封止膜30を突き破る屈曲部35を備え、屈曲部35は、封止膜30に対向する対向面に、封止膜30に向かって突出し、屈曲時に封止膜30に初期破れを生じさせる先鋭の突出片50を備える。【選択図】図1
