<P>PROBLEM TO BE SOLVED: To provide a multi-chamber container which reliably mixes medicaments and discharge the mixed medicament. <P>SOLUTION: A cylindrical insert 30 made of a rubber is press-fitted in and is welded to the inner circumference of a discharge outlet 12 inside the discharge outlet 12. The insert 30 is formed into a cylindrical shape with an elastomer rubber having an adequate thickness, and the central part is displaced due to the elasticity between a first state in which the central part is curved and protruded greatly into a hollow side of a medicament bag 10 and is substantially closed and a second state in which the central part is protruded to the side of a rubber stopper 20 and is opened. When the welded part between the separated chambers is not opened, the insert remains in the first shape, and the discharge of the medicament is prevented since the liquid flow is not initiated substantially even if the rubber stopper is punctured. The insert is transformed from the first shape into the second shape by liquid pressure at the time of the opening of the welded part. Since an opening part is formed on the insert 30, the medicament is discharged through the opening part. <P>COPYRIGHT: (C)2008,JPO&INPIT |
