[PROBLEMS] To provide a multichamber container composed of a drug solution bag which is made of a soft synthetic resin film and a drug container which can be attached to the drug solution bag, whereby drugs can be surely mixed together and then discharged. [MEANS FOR SOLVING PROBLEMS] A discharge port (12) has a cylindrical shape and a synthetic resin film forming a drug solution bag (10) is welded to the outer periphery of the discharge port (12) in such a manner that it can be easily peeled off due to the pressurization by the drug solution bag (10). The welded section (13) consists of a first area (L1) welded at a low sealing strength and a second area (L2) welded at a high sealing strength. The discharge port (12) has a continuous hole (18) formed in the second area (L2). Due to the pressurization by the drug solution bag (10), connection firstly occurs in the first area (L1) so that first and second partitioned chambers (23, 24) are connected together. Thus, first and second drug solutions contained in the first and second partitioned chambers (23, 24) are mixed together. Due to the continuous pressurization by the drug solution bag (10), connection finally occurs in the second area (L2) too so that the drug solution mixture is introduced into the discharge port (12) through the continuous hole (18) formed in the discharge port (12). |
