ABSTRACT:
A dispensing system for a plural component mixture including a first operator held container and separate flexible containers placed within the first container. Conduits coupled between the second containers and a dispensing device. The dispensing device includes a passageway and a valve for each respective component. An actuator controls the valves. A second valve is coupled in the conduits between the components' sources and the dispensing device. The second valve includes an inlet port for each component, an equal number of outlet ports, and an inlet port for flushing the plural components from at least portions of their respective conduits. The second valve has a first state where each inlet port is coupled to an outlet port and a second state where the inlet port for flushing material from the conduits and the mixed plural components is coupled to the outlet ports.
