Abstract
Abstract A technique for both cleaning up the crankcase oil changing process and recycling the oil for use as heating oil or, after refining, as lubricating oil, utilizes a shallow pan with a funnel defined on one edge which captures used oil from the engine crankcase, an oil can opener spout which makes a circular hole in the top of the oil can from which the fresh oil is poured into the crankcase after the used oil is drained, and a series of plugs which are inserted into the openings made by the oil can opener spout so that the used crankcase oil can be poured back into the cans the new oil came in by utilization of the special oil drip pan with the funnel extension.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
79 words
An oil changing kit comprising: (a) a flattened open-topped container; (b) a funnel extending from one side of said container and communicating with the interior thereof and dfines a partial lid for said container to catch otherwise spilled oil when said container is tilted toward said spout, whereby said container can be filled from a crankcase and drained into oil cans through said funnel; and (c) said funnel having a spout with a first valve in the tip thereof.
Claim 2
Dependent Claim
79 words
An oil changing kit comprising: (a) a flattened open-topped container; (b) a funnel extending from one side of said container and communicating with the interior thereof and dfines a partial lid for said container to catch otherwise spilled oil when said container is tilted toward said spout, whereby said container can be filled from a crankcase and drained into oil cans through said funnel; and (c) said funnel having a spout with a first valve in the tip thereof.
Claim 3
Dependent Claim
26 words
Structure according to claim 1 wherein said funnel has a second valve spaced toward the container from said first valve to define a metered volume therebetween.
Claim 4
Independent Claim
65 words
A method for reclaiming crankcase oil comprising the following steps: (a) draining the used oil from the crankcase into a container; (b) cutting a hole in a sufficient number of fresh oil cans to fill the crankcase; (c) pouring fresh oil from said cans into said crankcase; (d) pouring used oil from said container into said cans; and (e) plugging the holes in said cans.
Claim 5
Dependent Claim
26 words
A method according to claim 3 wherein said container has an integral funnel with a spout and step (d) includes filling said cans through said spout.
Claim 6
Dependent Claim
59 words
A method according to claim 4 wherein said funnel includes two spaced valves defining a volume therebetween no larger than the volume of one of said cans and step (d) includes first filling said funnel with a charge of used oil from said container and then discharging said charge by releasing the valve nearest the tip of said funnel.
Claim 7
Dependent Claim
42 words
A method according to claim 3 wherein step (b) is accomplished with an oil can opener spout which cuts a circular hole in a can and step (e) comprises pressing pre-formed circular plugs into the circular holes so cut in said cans.
