Abstract
A multi-chamber container of two liquid mixing type, aiming for obtaining an increased reliability for preventing an administration from being practiced under a non separated condition of a weak seal. The medical baghas an outer peripheral strong sealand a weak sealfor separating the space inside the medical bag into two partitionsand. At the tip end of an outlet port, a flapas a valve member is provided, which usually closes the outlet portto the space inside the medical bag. The flapis connected to the opposite surface of the medical bag, so that the flapis displaced in cooperation with an expansion deformation of the medical bag as obtained when the weak sealis opened, resulting in opening of the outlet port. The flap is formed with a small holefor limiting a liquid flow amount to a small value. When an infusion operation being started under the non-opened state of the weak seal, the liquid flow amount to the outlet port is restricted to a small amount by the small hole, thereby notifying the non-opened state of the weak seal and warning that the weak seal should be opened.
