A TAP-HEAD (10) TO DISPENSE LIQUIDS WHEREIN THE TURN ON AND TURN OFF CONTROL IS DISPOSED AT THE OUTLET PORT. IT COMPRISES A HOUSING BODY (12), THREE CYLINDRICAL BODIES (14,20,28), BIASING MEANS, AND A SEALING MEANS CONFIGURED TO REGULATE THE FLOW OF LIQUID THROUGH THE TAP-HEAD. BY APPLYING PRESSURE AGAINST THE CYLINDRICAL BODIES THE CYLINDRICAL BODIES ARE ALIGNED TO ALLOW FLOW OF LIQUID OUT. A TWISTING MEANS IS PROVIDED TO HOLD THE ASSEMBLY IN AN OPEN POSITION. BY FURTHER TWISTING THE ASSEMBLY, THE FLOW OF LIQUID IS STOPPED.(FIG. 2)
