Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
208 words
Trash barrel, comprising: (a) a single-piece plastic container having four upper tapered side walls, four lower tapered side walls which are generally extensions of the upper side walls, but are spaced inwardly of and parallel with the upper side walls, and a bottom surface, said four lower side walls forming a downwardly-extending pedestal adapted to engage the ground, and an abutment extending laterally from the pedestal, the bottom of said abutment being higher than the bottom of the pedestal, and the opposite outer side surfaces of the abutment being spaced inwardly of the respective outer opposite side surfaces of the pedestal, and (b) a pair of wheels rotatably mounted on the opposite side surfaces of the abutment, the wheels being generally tangential to a ground plane including the bottom of the pedestal and lying entirely within an envelope defined by the planes of the outer surfaces of the upper side walls and the ground surface, so that, when the trash barrel is nested with other identical trash barrels, the trash barrel is supported by contact of its upper side walls only with the upper side walls of the next lower trash barrel and the wheels do not contact the lower side walls of said next lower trash barrel.

Trash barrel, comprising: (a) a single-piece plastic container having four upper tapered side walls, four lower tapered side walls which are generally extensions of the upper side walls, but are spaced inwardly of and parallel with the upper side walls, and a bottom surface, said four lower side walls forming a downwardly-extending pedestal adapted to engage the ground, and an abutment extending laterally from the pedestal, the bottom of said abutment being higher than the bottom of the pedestal, and the opposite outer side surfaces of the abutment being spaced inwardly of the respective outer opposite side surfaces of the pedestal, and (b) a pair of wheels rotatably mounted on the opposite side surfaces of the abutment, the wheels being generally tangential to a ground plane including the bottom of the pedestal and lying entirely within an envelope defined by the planes of the outer surfaces of the upper side walls and the ground surface, so that, when the trash barrel is nested with other identical trash barrels, the trash barrel is supported by contact of its upper side walls only with the upper side walls of the next lower trash barrel and the wheels do not contact the lower side walls of said next lower trash barrel.
Claim 3
Dependent Claim
25 words
Trash barrel as recited in claim 1, wherein the bottom of the abutment is connected to the bottom of the pedestal by a curved surface.
Claim 4
Dependent Claim
46 words
Trash barrel as recited in claim 2, wherein a handle is mounted on the upper portion of the side wall extending above the wheels, so that pulling on the handle causes the container to rotate about the wheel axis and lift the pedestal from the ground.
Claim 5
Dependent Claim
19 words
Trash barrel as recited in claim 3, wherein a cover fits snugly over the top edge of the container.
