Abstract
Abstract Disclosed herein is an oil filler cap for disposition upon the rocker cover in an internal combustion engine in which the opening mechanism commonly used for opening oil cans to allow the lubricant to pass within the engine is integral with the valve cap itself. Specifically, the device includes an inverted cone having a hardened tip area at its vertical extremity, an overlying protective shroud, plural openings disposed on the conical area, and an upper pinch plate for latching the cap onto the valve cover itself. Cooperating with the pinch plate is an underlying outwardly flared terminus having tab members to allow co-action with a latch upon the rocker cover.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
263 words
An oil filler cap comprising in combination: a tube with latching means on a lower portion thereof for attachment to an oil inlet on a car, a hardened tip on a top portion of said tube used to puncture an oil can, a flared skirt medial portion tapering towards said tip of said tube between said upper and lower portions provided with openings therethrough, whereby when an oil can is punctured on said tip and forced on said flared skirt medial portion, the puncture is enlarged and oil passes through said openings down said tube and into the oil inlet of the car, an overlying protective cap extending over said tip and tapering medial portion whereby when not in use said tip is not exposed and oil vapors are contained within said cap, said latching means comprises an outwardly flared terminus on the lowermost portion of said tube, at least two tab members extending outwardly from said terminus, and a pinch plate above said terminus extending outwardly from said tube whereby said terminus is placed below the oil inlet and said pinch plate thereabove, said tab members oriented to pass through the inlet and when rotated will force and secure said pinch plate down and around said inlet, and said pinch plate comprises an annular flange extending outwardly from said tube having diametrically opposed ears along an outer periphery thereof, an outer lip integral with said ears, a recessed annular top groove within said outer lip, a concentric annular upstanding channel member within said groove and a circular recess within said channel member.

Claim 3
Dependent Claim
51 words
The device of claim 1 wherein a gasket is provided between said pinch plate and said terminus to provide a vapor seal when tightened against an area around the oil inlet, and an annular seal resides within said circular recess to provide a tight fit with said cap which sits thereon.
Claim 4
Dependent Claim
27 words
The device of claim 1 in which a spring plate is disposed between said pinch plate and said gasket for providing tension along the vapor seal area.
Claim 5
Dependent Claim
23 words
