There is provided an apparatus and method for the collection and transfer of a liquid, which is preferably waste oil. The apparatus includes a tank having a top opening with a hollow tube projecting from the top opening into the interior of the tank. A hollow stem is slidably received within the hollow tube. A funnel, which initially receives the liquid, is attached to the top end of the stem which is located outside of the tank. An opening is provided in the wall of the stem near the lower end which is located inside the tank. A cover plate is received about the bottom of the stem. The hollow tube and the lower portion of the stem form a valve so that when the stem is raised, the opening in the stem is covered by the hollow tube, and thus is sealed from the inside of the tank, so that the liquid does not flow through the opening in the stem, and when the stem is lowered, the opening in the stem is outside of the hollow tube so that liquid may flow through the opening in the stem, which permits the liquid to be collected inside the tank. When the liquid is to be transferred out of the tank, the stem is raised, thereby closing the valve. Gas pressure is applied to the inside of the tank and the pressurized liquid is discharged from the tank through a liquid exit port which is located in the lower portion of the tank.
A method for the collection and transfer of a liquid utilizing a tank having a first opening therein and a hollow tube extending from the first opening into the tank, and further utilizing a hollow stem including a wall and first and second ends with a portion of the hollow stem being slidably received in the hollow tube with an opening in the wall of the stem and with the hollow tube and opening in the wall of the stem forming a valve, comprising the steps of:
