<P>PROBLEM TO BE SOLVED: To reliably prevent administration in an unopened state with respect to a multi-chamber container which includes a drug solution bag having a plurality of chambers to respectively and independently seal and store drug solutions by being separated with a weak seal part and which mixes the drug solutions by opening the weak seal part with the pressurization of the drug solution bag. <P>SOLUTION: A cap 24 is mounted for covering onto a discharge port 12. A needle shape member 28 is projected integrally to the inner cavity of the drug solution bag 10 from the inner surface side of the cap 24. A needle shape member end part 28' is extended to a weak seal part 18. The opposing surfaces of the drug solution bag 10 are made to adhere via the end part 28' when the weak seal part 18 is formed. When the weak seal part 18 is not opened, the cap 24 is not removed since the needle shape member end part 28' is made to adhere onto the weak seal part 18, so that puncturing is not also performed. When the seal part is opened, the opposing surfaces of the drug solution bag 10 constituting the weak seal part 18 are separated so as to separate and remove the needle shape member end part 28'. Thus, puncturing is performed with an infusion set. <P>COPYRIGHT: (C)2007,JPO&INPIT |
