Abstract: A graduated proportioning and mixing container is disclosed, which includes two liquid-receiving compartments and a mixing compartment. One liquid-receiving compartment is larger than the other, and both are graduated to indicate ratio-designated levels, by which two liquids may be mixed in definite, accurately and precisely determined ratios. The preferred use of the container is for preparation of two-cycle fuel mixes, containing certain various ratios of gasoline to oil. The smaller of the two liquid-receiving compartments is downwardly tapering, with the volume of the downwardly tapering compartment decreasing toward the bottom of the container. The larger compartment has a complimentary shape, so that the container as a whole has a rectilinear shape. The container further includes two openings, one associated with each liquid-receiving compartment, and each opening has a threaded cap. Each opening is adapted to provide a triple seal, in order to avoid leakage of the contents.

Abstract: 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.
