Abstract: A medical container with an electrolyte solution stored therein is disclosed. It is formed of a resinmade container main body, a base solution compartment, at least one isolated compartment or connected compartment, and an openable portion. The base solution compartment is arranged in the container main body and is filled with the electrolyte solution in a state steamsterilized together with the container main body. The isolated compartment or connected compartment is arranged in the container main body, is isolated from the base solution compartment by an isolation wall interposed therebetween, and is filled with a bicarbonate. The openable portion permits aseptic communication between the base solution compartment and the isolated compartment or connected compartment by an operation from an outside of the container main body at the time of use. The openable portion is formed at at least a part of the isolation wall.

Abstract: Disclosed herein is a container in which a mixture of resins having different melting starting temperatures is used as a heat-sealable layer. The heat-sealable layer is heat-sealed at two or more locations under different conditions so that at least one hermetic heat seal and at least one heat seal having easy-to-peel openability are formed to define plural compartments isolated from one another. The compartments can be filled with different materials. These materials are isolated from one another until immediately before use. Upon application, the heat seal having easy-to-peel openability is broken from the outside to permit mixing of the materials. The container is useful for foods, medical and pharmaceutical substances, and the like.
