[PROBLEMS] To provide a multiple liquid drug mixing type of drug bag wherein one time operation for opening a weak seal can also open the entrance for injection of a drug to be compounded. [MEANS FOR SOLVING PROBLEMS] A drug bag (10) is formed from a soft material in a film form, the inner cavity is partitioned by a weak seal section (18) into a plurality of cells (20, 22), and an entrance member (14) for the injection of a drug to be compounded is provided so as to face one (20) of the cells. The entrance member (14) for the injection of a drug to be compounded has sealed cells (36A, 36B and 36C) for storing drugs, cells (36A, 38B and 36C) store drugs to be compounded and are usually closed by an exfoliatable film (44), to stop the injection of the drug to be compounded to the drug bag (10). The exfoliatable film (44) is pressure-sensitively adhered strongly to the opposite surface of the plastic film constituting the drug bag. When the drug bag (10) is subjected to expansion deformation by the pushing pressure caused in the opening of the weak seal section (18), the exfoliatable film (44) undergoes expansion displacement together with the bag, the exfoliatable film (44) is exfoliated from the entrance member (14) for the injection of a drug to be compounded, and thus drugs to be compounded are injected to the drug bag (10) from respective cells (36A, 38B and 36C). |
