DOUBLE-CELL CONTAINER

摘要

Intended is to make the reliability of a dosage-preventing action higher when a weak seal portion is not opened yet in a double-cell container of a double-drug mixing type. The double-cell container comprises a strong seal portion (14) at the outer periphery of a drug bag (10), and a weak seal portion (18) for partitioning the inside into two cells (20 and 22). At the leading end of an exit (12), there is disposed a flap (28) acting as an opening/closing member, which normally closes the exit (12) from the inside of the drug bag. The flap (28) is connected at a point seal (43) to the drug bag confront face, and is displaced in association with the bulging deformation of the drug bag at the time when the weak seal portion (18) is opened, thereby to open the exit (12). The flap (28) has a small hole (44) formed to throttle the liquid flow to a small quantity. Even if a transfusion is intended with the weak seal portion being unopened, therefore, the liquid quantity to a transfusion set is throttled by the small hole (44) so that the unopened state of the weak seal portion can be understood to promote the opening of the weak seal portion.
