PROBLEM TO BE SOLVED: To provide a mixer, mounted by simple operation to perform mixing, and simply detached after mixing to be used as a container holding the mixed agent.SOLUTION: In this two-chamber container, a first holding chamber R1 is partitioned by a first movable wall A6 and a second movable wall A7, a second holding chamber R2 is partitioned above the second movable wall A7, and a communicating recessed part 13 communicating the interior of the first holding chamber R1 with the interior of the second holding chamber R2 through the outer periphery of the second movable wall A7, when the first movable wall A6 is pushed in, is recessed in the inner periphery of the second holding chamber R2. A cylindrical base B4, where the two-chamber container A can be locked to be prevented from slipping out upward and the two-chamber container is removably fitted, is rotatably mounted on a pedestal B1, and a mechanism for lifting a pressing body B6 with small force by relative rotation of the cylindrical base B4 to the pedestal B1 is provided. The first movable wall A6 is pushed up by the tip of the rising pressing body B6 to mix two agents in the respective holding chambers.COPYRIGHT: (C)2012,JPO&INPIT【課題】簡単な操作で装着して混合し、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供する。【解決手段】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R1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、二室容器Aを上方への抜け出しを防止した状態で係止可能で、且つ二室容器が着脱可能に嵌合される筒状基体B4を、台座B1上に回転可能に装着し、台座B1に対する筒状基体B4の相対回転により、押圧体B6を小さな力で上昇させる機構を備え、上昇する押圧体B6の先端により第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
