A volumetric measuring/dispensing device for liquids is provided which has a measuring container having graduation markings thereon for measuring the quantity of liquid in the container. The container has an upper valve housing and a lower valve housing mounted in the top and bottom of the container. A valve stem having a single handle extends through the upper and lower valve housings and is selectively turnable by a turning the single handle to a selected one of three different positions, namely: a filling position, a closed position and an emptying position. When in the filling position, the upper and lower housings in conjunction with the valve stem respectively provide for the entrance of liquid into the interior of the container while at the same time provide for the exit of air out of the container. When in the closed position, the upper and lower housings in conjunction with the valve stem respectively provide for the closure of all entrances into and exits out of the container by both liquid and air. When in the emptying position, the upper and lower housings in conjunction with the valve stem respectively provide for the entrance of ambient air into the interior of the container while at the same time provide for the exit of liquid out of the interior of the container.
