Abstract
Abstract A device for the convenient collection and disposal of liquids and particularly liquids such as automobile waste oil is disclosed. The device includes a receptacle comprising a bottom wall and peripheral side walls defining in part an open central portion having a downwardly inwardly extending funnel-shaped central wall adapted for initial receipt of such liquid. The funnel terminates in a valved conduit which projects beneath the bottom wall of the receptacle so as to conveniently provide access for containers and the like into which the waste oil may then be directed. A detachable cover adapted to enclose the open central portion of the receptacle is provided so that when the cover is in place the receptacle may be used for the temporary storage and transportation of such waste oil in a convenient and clean manner.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
251 words
A device for the convenient collection and disposal of liquids such as automobile waste oil comprising a generally rectangular receptacle having a bottom wall and peripheral side walls, a downwardly inwardly extending funnel-shaped central wall for receipt of liquid thereon, said central wall having an open top and projecting through said bottom wall and terminating in a downwardly extending conduit for directing said liquid from said central wall outwardly of said receptacle as to containers adapted for placement therebeneath, said side walls, said bottom wall and said central wall cooperatively forming a hollow enclosed storage chamber surrounding said central wall and disposed within said receptacle, means opening through one of said side walls providing access to said chamber, said conduit including valve means for controlling the flow of said liquid through said conduit, said receptacle further including a detachable cover positioned over and adapted to close said open top, said cover contacting upper portions of said central wall in liquid sealing relationship thereto so that liquid may be temporarily transported in said receptacle and means for positioning said receptacle for receipt of containers beneath said conduit, said positioning means including vertically adjustable legs downwardly extending from said bottom wall, said conduit terminating above the uppermost possible position of said legs such that said conduit is displaced from a supporting surface for said legs, said legs each having a removable extension attached thereto, said legs and extensions slidably nested and means for maintaining the relative positioning of said legs and said extensions.
Claim 2
Independent Claim

A device for the convenient collection and disposal of liquids such as automobile waste oil comprising a generally rectangular receptacle having a bottom wall and peripheral side walls, a downwardly inwardly extending funnel-shaped central wall for receipt of liquid thereon, said central wall having an open top and projecting through said bottom wall and terminating in a downwardly extending conduit for directing said liquid from said central wall outwardly of said receptacle as to containers adapted for placement therebeneath, said side walls, said bottom wall and said central wall cooperatively forming a hollow enclosed storage chamber surrounding said central wall and disposed within said receptacle, means opening through one of said side walls providing access to said chamber, said conduit including valve means for controlling the flow of said liquid through said conduit, said receptacle further including a detachable cover positioned over and adapted to close said open top, said cover contacting upper portions of said central wall in liquid sealing relationship thereto so that liquid may be temporarily transported in said receptacle and means for positioning said receptacle for receipt of containers beneath said conduit, said positioning means including vertically adjustable legs downwardly extending from said bottom wall, said conduit terminating above the uppermost possible position of said legs such that said conduit is displaced from a supporting surface for said legs, said legs each having a removable extension attached thereto, said legs and extensions slidably nested and means for maintaining the relative positioning of said legs and said extensions.
Claim 3
Dependent Claim
53 words
The device set forth in claim 1, said conduit being a tube projecting below said bottom wall and said flow control means being a valve mounted in said tube, said tube and valve readily accessible for manipulation by means of relatively wide open areas defined between said legs and below said bottom wall.
Claim 4
Dependent Claim
54 words
The device set forth in claim 1, said receptacle including a top wall inwardly extending from said side walls and terminating with peripheral upper portions of said central wall, said cover having a bottom wall and a peripheral flange downwardly extending therefrom, said flange adapted to sealingly engage with said upper central wall portions.
Claim 5
Dependent Claim
34 words
The device set forth in claim 3, said flange and said upper central wall portions having cooperating locking means whereby relative rotation of said cover with respect to said receptacle sealingly closes said receptacle.
Claim 6
Dependent Claim
40 words
The device as set forth in claim 4, said locking means being a bayonet type wherein said cover includes a pair of spaced lugs adapted to underlie projections inwardly extending from said upper central wall portions upon said relative rotation.
Claim 7
