Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
194 words
A waste container, comprising a metal body having longitudinally extending side walls, laterally extending end walls, a bottom wall, and a top wall having a large unobstructed access opening therein which is surrounded by an upstanding rim, a lid of fiberglass reinforced plastic or other relatively light weight material having a downwardly extending lip for disposal about the rim when the lid is over the opening to close same, and means by which the lid may be moved between its closed position and a generally upright, suspended position adjacent either side of the container, including means for raising and lowering the lid between its closed position and a raised position in which its lip is above the rim, and supporting the lid, when so raised, for guided, lateral movement toward and away from a position overhanging either side of the body, and means for engaging the lid, as it is moved into overhanging position, to permit it to be swung into its upright, suspended position, and then to be swung back into its overhanging position for guided lateral movement to a position above the opening, from which it may be lowered to closed position.
Claim 2
Dependent Claim
194 words
A waste container, comprising a metal body having longitudinally extending side walls, laterally extending end walls, a bottom wall, and a top wall having a large unobstructed access opening therein which is surrounded by an upstanding rim, a lid of fiberglass reinforced plastic or other relatively light weight material having a downwardly extending lip for disposal about the rim when the lid is over the opening to close same, and means by which the lid may be moved between its closed position and a generally upright, suspended position adjacent either side of the container, including means for raising and lowering the lid between its closed position and a raised position in which its lip is above the rim, and supporting the lid, when so raised, for guided, lateral movement toward and away from a position overhanging either side of the body, and means for engaging the lid, as it is moved into overhanging position, to permit it to be swung into its upright, suspended position, and then to be swung back into its overhanging position for guided lateral movement to a position above the opening, from which it may be lowered to closed position.
Claim 3
Dependent Claim
57 words
A waste container of the character defined in claim 1, wherein the lid includes a flange extending outwardly from each end, and the means for raising and lowering the lid comprises a frame and linkage connecting the frame to the top wall of the container body for vertical movement beneath the flange to raise and lower it.
Claim 4
Dependent Claim
62 words
A waste container of the character defined in claim 2, wherein the lid carries a deformable seal ring positioned to engage the rim as the lid is closed, and the frame has means thereon which engages the lid to hold it in closed position and the seal ring sealably engaged with the rim as the linkage moves over a dead center position.
Claim 5
Dependent Claim
36 words
A waste container of the character defined in claim 3, wherein the linkage is also constructed and arranged to hold the lid in its raised position as the linkage is moved over another dead center position.
Claim 6
Dependent Claim
194 words
A waste container, comprising a container body having longitudinally extending side walls, laterally extending end walls, a bottom wall, and a top wall having an access opening therein which is surrounded by an upstanding rim, a lid having a downwardly extending lip for disposal about the rim when the lid is over the opening to close same, and means by which the lid may be moved between its closed position and a generally upright, suspended position adjacent one side wall of the container, including means on the body adjacent each end of the opening for raising and lowering the lid between its closed position and a raised position in which its lip is above the rim, and supporting the rim, when so raised, for guided, lateral movement toward and away from a position overhanging said one side wall of the body, and means for engaging the lid, as it is moved into overhanging position, to permit it to be swung into its upright, suspended position, and then to be swung back into its overhanging position for guided lateral movement to a position above the opening, from which it may be lowered to closed position.

194 words
A waste container, comprising a container body having longitudinally extending side walls, laterally extending end walls, a bottom wall, and a top wall having an access opening therein which is surrounded by an upstanding rim, a lid having a downwardly extending lip for disposal about the rim when the lid is over the opening to close same, and means by which the lid may be moved between its closed position and a generally upright, suspended position adjacent one side wall of the container, including means on the body adjacent each end of the opening for raising and lowering the lid between its closed position and a raised position in which its lip is above the rim, and supporting the rim, when so raised, for guided, lateral movement toward and away from a position overhanging said one side wall of the body, and means for engaging the lid, as it is moved into overhanging position, to permit it to be swung into its upright, suspended position, and then to be swung back into its overhanging position for guided lateral movement to a position above the opening, from which it may be lowered to closed position.
Claim 8
Dependent Claim
53 words
A waste container of the character described in claim 5, wherein said means engagable with the lid includes a hanger pivotally connected to the container body near said one side to support the lid for pivoting with the lid into its generally upright, suspended position adjacent the one side wall of the body.
Claim 9
Dependent Claim
28 words
A waste container of the character described in claim 6, including means yieldably urging the hanger into a position in which it is so engaged by the lid.
Claim 10
Dependent Claim
52 words
