PROBLEM TO BE SOLVED: To provide a mixing device for a two-chamber container which is mounted on the two-chamber container A through simple operation for mixing in use and after mixing, is easily separated from the two-chamber container A and allows the two-chamber container A to be used as a container where an admixture is contained, wherein the two-chamber container A includes a first storage chamber R1 defined by a first mobile wall A6 and a second mobile wall A7 a second storage chamber R2 defined above the second mobile wall A7 and a communication recess 13 which communicates the first storage chamber with the second storage chamber R2 via the outer periphery of the second mobile wall A7 when the first mobile wall A6 is pushed-in and which is provided in a concave manner in the inner periphery of the second storage chamber R2.SOLUTION: The mixing device is constituted in such a way that: a cylindrical base body B2 is rotatably mounted on a seat B1, which is locked to prevent the two-chamber container A from coming off upward and is fitted in the two-chamber container A so that the two-chamber container A can be separated two drugs in respective storage chambers are mixed by pushing up the first mobile wall A6 by the distal end of the pressurizing cylinder B3 which ascends by an incorporated ascending/descending mechanism having a thread member B4 and a linkage member B5 by the relative rotation of the seat B1 and the cylindrical base bodies B2.COPYRIGHT: (C)2011,JPO&INPIT【課題】第1可動壁A6及び第2可動壁A7で第1収容室R1を区画し、第2可動壁A7上方に第2収容室R2を区画し、第1可動壁A6の押し込み時に第2可動壁A7外周を介して第1収容室内と第2収容室R2内とが連通する連通凹部13を第2収容室R2内周に凹設した二室容器Aに対し、それらを使用時に簡単な操作で装着して混合し、また、混合後は簡単に離脱させて混合剤が収容された容器として使用することができる混合装置を提案する。【解決手段】二室容器Aの上方への抜け出しを防止すべく係止し且つ二室容器Aの離脱が可能に嵌合させた筒状基体B2を台座B1上に回転可能に装着し、台座B1と筒状基体B2との相対回転により、螺子部材B4と、連係部材B5を備えた内蔵昇降機構により上昇する押圧筒B3の先端で第1可動壁A6を押し上げて各収容室内の二剤を混合する如く構成した。【選択図】図1
