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.

[ I claim:] [1.] A tamper evident cap for use in combination with a liquid dispensing system comprising a container having an access opening in communication with an internal chamber for containing the liquid to be dispensed and a dispensing valve mounted within the access opening, the dispensing valve including a body portion having a coupler receiving opening provided with a capture surface, the tamper evident cap functioning to close the coupler receiving opening and comprising:(a) a top wall including a removable segment; and(b) a yieldably deformable skirt portion connected to and circumscribing said top wall, said skirt portion including locking means for lockably engaging the capture surface of the coupler receiving opening to prevent removal of said cap therefrom until said removable segment is removed to permit said skirt portion to be inwardly deformed a sufficient distance to allow removal thereof from the coupler receiving opening.
