Abstract:
1. A medical liquid container having a primary liquid medicament-housing chamber for housing a medicament and at least one secondary liquid medicament-housing chamber for housing a liquid medicament smaller in the amount than the liquid medicament housed in the primary liquid medicament-housing chamber, which is connected to the primary liquid medicament-housing chamber, an inside of the primary liquid medicament-housing chamber and an inside of the secondary liquid medicament-housing chamber being communicatably divided, wherein said secondary liquid medicament-housing chamber has a bulge part bulged such that the internal medicament-housing space before housing a medicament is larger than the volume of the housed medicament, the secondary liquid medicament-housing chamber is liquid tightly sealed, and communicatably divided from the primary liquid medicament-housing chamber, the liquidtight seal is formed at the outside of the primary liquid medicament-housing chamber, the end part of the secondary liquid medicament-housing chamber is inserted into the primary liquid medicament-housing chamber and heat-sealed, and the primary and secondary liquid medicament-housing chambers are made of a sheet material having a multilayer structure in which a heat sealing temperature at a joining of the outer face of the secondary liquid medicament-housing chamber with the inner face of the primary liquid medicament-housing chamber is lower than a melt-bonding temperature of inner faces of the secondary liquid medicament-housing chamber with each other.
