Abstract
Abstract Grease disposal apparatus for use under an automotive vehicle, which includes a grease pan having a central portion adapted to rest upon the floor surface with the outer circumference of the pan being elevated so that grease collect thereon will run downward to the central portion, a quantity of grease-absorbent material placed upon the pan central portion but removable therefrom, and a removable cover over the grease-absorbent material. A grease pan having a raised outer edge which is resiliently supported so that it will temporarily deflect towards the floor surface when a vehicle tire runs upon it, and being of such configuration that wind currents blowing across the grease pan will not exert a significant lifting force upon the pan either by blowing into a gap underneath the pan edge or by the airfoil of blowing across its upper surface.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
Grease disposal apparatus comprising, in combination: an integrally formed base member made of a plastic material, having a base portion with a flat generally circular upper surface thereon, a peripheral wall surrounding said flat surface and having a number of grease entry ports formed therein, and a generally cylinder pedestal rising up from the center of said flat circular surface and substantially concentric therewith; an elongated flat strip of grease absorbent material formed into a roll with a central opening therein, said roll having one end face thereof disposed upon said flat circular surface of said base member and said central opening thereof receiving said pedestal; a generally circular cover member disposed above and covering said roll, the peripheral edge of said cover member being disposed in close proximity to the upper surface of said peripheral wall of said base member; and means detachably securing the center of said cover member to said pedestal of said base member.
Claim 2
Dependent Claim
158 words
Grease disposal apparatus comprising, in combination: an integrally formed base member made of a plastic material, having a base portion with a flat generally circular upper surface thereon, a peripheral wall surrounding said flat surface and having a number of grease entry ports formed therein, and a generally cylinder pedestal rising up from the center of said flat circular surface and substantially concentric therewith; an elongated flat strip of grease absorbent material formed into a roll with a central opening therein, said roll having one end face thereof disposed upon said flat circular surface of said base member and said central opening thereof receiving said pedestal; a generally circular cover member disposed above and covering said roll, the peripheral edge of said cover member being disposed in close proximity to the upper surface of said peripheral wall of said base member; and means detachably securing the center of said cover member to said pedestal of said base member.
Claim 3
Dependent Claim
36 words
Apparatus as in claim 1 wherein the thickness of the roll is greater than the height of said grease entry ports, and the cover member is downwardly curved on its peripheral edge to a cup-shaped configuration.
Claim 4
Dependent Claim
152 words
Grease disposal apparatus comprising, in combination: an integrally formed grease pan having a central portion adapted to rest upon the floor surface, a main portion extending radially outwardly from said central portion and at the same time upwardly to an elevated position above the floor surface so as to collect grease and cause same to flow down into and upon said central portion, and a circumferentially extending peripheral apron portion which extends outwardly from said main portion and then downwardly to supportingly engage the floor surface, said apron being resilient whereby the elevated portion of said pan may be temporarily deflected downward to the floor surface whenever a vehicle tire runs thereupon; a quantity of grease-absorbent material removably disposed upon said pan central portion; and a cover removably disposed above said grease-absorbent material and cooperating with said pan to provide multiple paths through which grease may flow into said pan central portion.
Claim 5
