It is something which has with the medicine where as for the drug box, the liquid has the opening section which is entrance and exit possible on Tip side, is enclosed by main internal of the container itself and the container which are formed with the material which possesses flexibiility, through the opening section, is dissolved by the liquid inflow. It concatenates with the frame part and at least the compressed section and the frame part which of one side among the compressed sections of pair are provided in rim of the compressed section and the compressed section of the pair where with this drug box, as for the container itself, it minded the gap in the initial state which the liquid is not restoration by main internal of the container yet and opposed and was provided, forms compressed form possesses with the deformation possible easily transformable part easily, the case the liquid restoration to main internal of the container, the compressed section initial state compared to alienating mutually due to the fact that the easily transformable part becomes deformed, the container itselfIn order for capacity to increase, it is constituted.薬剤収納容器は、先端側に液体が出入り可能な口部を有し、可撓性を有する材料で構成された容器本体と、容器本体内に収納され、口部を介して流入した液体によって溶解される薬剤とを備えるものである。この薬剤収納容器では、容器本体は、容器本体内に未だ液体が充填されていない初期状態で間隙を介し対向して設けられた、扁平形状をなす一対の扁平部と、扁平部の外周に設けられた枠部と、一対の扁平部のうちの少なくとも一方の扁平部と枠部とを連結し、容易に変形可能な易変形部とを有し、容器本体内に液体が充填された際には、易変形部が変形することにより、扁平部同士が互いに初期状態よりも離間して、容器本体の容積が増大するよう構成されている。
