Abstract
A system for the filling, transport and emptying of liquid containers which include a novel coupler mechanism for interconnection with a coupler operated extractor valve provided on the liquid container. The coupler includes a novel coupler flow control assembly for preventing liquid trapped within the coupler body from leaking back into the container to which the coupler is connected. More particularly, the coupler includes a novel one-way valve mechanism which permits liquid to be pumped from the container to which the coupler is interconnected, but positively blocks the flow of liquid in the opposite direction toward the container reservoir.
