ABSTRACT:
Disclosed herein is a filled and sealed, self-contained mixing container. The container has compartments which are isolated from each other. Plural substances which contain components susceptible to mutual reaction unless isolated from each other are contained in the respective compartments. In use, these compartments are communicated together so that the individual contents can be mixed within the container. A flow passage or passages, each of which has an isolator for the contents and is adapted to communicate the compartments with each other, and is formed by a side channel provided on an outer surface of a wall of the container. Mixing of the contents without exposure to the external atmosphere can be realized by irreversible destruction of the isolator upon use. The container is suited particularly for a closed therapy system.
