ABSTRACT:
Two valve plugs project upwardly from a liquid containing tank and are each covered by a one-piece cap of molded plastics material. Each cap includes an inverted cup-shaped cylindrical portion completely enclosing the upper portion of the plug and integrally connected to a larger depending annular skirt portion by peripherally spaced frangible ties. Peripherally spaced spring finger elements are integrally molded with the skirt portion for positively engaging the valve plug to lock the cap to the valve plug. The skirt portion has at least one vertical slot and a tab which is pulled to tear the frangible ties and separate the skirt portion and the finger elements from the cover portion when access to the valve plug is desired. In one embodiment, the spring finger elements hook onto a frusto-conical portion of the valve plug, and in another embodiment, the finger elements engage radially projecting coupling pins on a valve plug.
