A spout that fits all quart containers is characterized by a twist of the wrist to start and stop oil flow. The spout consists of a tubular cylinder into which an angled ball valve seat and a bubble run-off area has been incorporated. A steel ball moving on and off its valve seat due to the angle of the valve seat and gravity stops and starts the oil flow. When the bubble run-off area is pointed down, causing the steel ball to lodge itself in the bubble run-off area, the oil flows and with a twist of the wrist, making a 180 degree rotation of the spout, the bubble run-off area points up causing the steel ball to seat itself on the valve seat and the oil flow stops. The spout is excellent for hard to reach places and eliminates oil spills. Two tip sizes are incorporated in the spout for small and large filler openings. The small tip is for lawnmower and motorcycles for example and the larger for cars for example. The larger opening is obtained by cutting with a knife or razor or other cutting instrument the spout in a molded recessed area inward of the smaller tip.

A pour spout adapted to dispense oil or other liquid from a container comprising a tubular body having an inlet portion and an outlet portion, the inlet and outlet portions having a generally common longitudinal axis, a valve seat disposed within said body between said inlet and outlet portions, a heavy valve ball in the body adapted to selectively close the valve seat to prevent flow of liquid from the inlet portion to the outlet portion, means in the inlet portion retaining the ball in a zone adjacent the valve seat, a ball run-off area in the inlet portion eccentric to said axis adapted to receive the ball at a location sufficiently displaced from the seat to allow flow of liquid through the body from the inlet portion to the outlet portion, the valve seat lying in a plane forming an oblique angle with respect to said axis, the orientation of the plane of the valve seat being such that the area of the seat adjacent the run-off area is downstream with reference to the direction of flow through the body relative to the area of the seat remote from the run-off area, the body being constructed and arranged in combination with said valve ball such that when the body is disposed with its outlet portion lower than its inlet portion and the ball run-off area in a non-pour position above the axis, the valve ball closes the valve seat and with the ball run-off area in a pour position below the axis, the valve ball is readily received in the ball run-off area to open the valve seat without a significant tendency to stick on the valve seat due to surface tension forces of the liquid being dispensed.
