<p>A liquid transfer system which minimizes user exposure to hazardous materials, effectively addresses new governmental regulations and provides a positive methods for deterring system tampering. The liquid transfer system includes a novel valve mechanism which can be connected to a container such as a metal or plastic drum, and a coupler mechanism which can be removably coupled with the valve mechanism for operating the valve mechanism. An important aspect of the liquid transfer system is a tamper evident closure cap for closing the top to the dispensing valve mechanism of the system. The tamper evident cap is of a unique character such that it must be broken before access to the container can be achieved. The top opening of the valve mechanism is uniquely configured so that it will accept only couplers of a particular compatible design. In this way, couplers and valves can be custom designed for individual users and use of, or tampering with, containers belonging to the individual user by users of similar systems if positively prevented.</p> |
