ABSTRACT:
A fluid dispenser for a bulk container of the type having a rigid outer box with a sealable flexible plastic inner bag. The dispenser includes a tubular sleeve having a flange that is heat-sealed to the outer surface of the plastic bag and a tubular turncock having a pointed inner end for piercing the bag of fluid. Extending from the tubular surface of the turncock barrel are keys that engage keyways in the bore of the tubular sleeve that both restrict longitudinal movement of the turncock to prevent removal or bag-piercing during storage and shipping and also, after the turncock is fully inserted to pierce the bag, restricts rotational movement of the turncock to prevent accidental removal and possible leakage. A second embodiment of the invention replaces the turncock with a conduit having the keys and the pointed tip, but with a tube fitting at the opposite end for dispensing the fluid at a remote valve or pump.
