ABSTRACT:
A coupling head assembly for coupling a source container of chemical in a closed system, the assembly including a main passageway for flow of chemical from the container, an auxiliary passageway for rinsing the container when connected to a source of rinse liquid, and a second auxiliary passageway connectable to such source of rinse liquid for rinsing at least one flow line of the system to the exclusion of the container. A control device provides for performing each of the three functions. While withdrawing the chemical from the container, the control device informs the operator by a signal, of the functioning status of the coupling head assembly.
