Abstract
Abstract Disclosed is an improved cover or door for a bin type refuse container. In a preferred two-piece embodiment the invention comprises an upper member and a lower member joined together to form a generally unitary structure. A plurality of water channeling troughs or ribs are formed on the upper surface (upper member) of the cover. A plurality of support ribs are formed on the lower surface (lower member) of the member. In a preferred single piece embodiment, the invention comprises a ribbed, grooved, channeled, or corrugated platform member with lips or flanges extending downwardly from the periphery thereof so as to form a grooved, ribbed, channeled or corrugated platform like member with a slightly concaved underside. A plurality of support rods, tubes or other members extend across the underside of the platform like member abutting against the opposing edge lips or flanges. Two of these single piece covers may be formed simultaneously by rotomolding with subsequent severence of the rotomolded part into two mirror-image halves. In both the single piece and double piece embodiment, the upper surface may be peaked, arched or bowed to facilitate channeling and runoff of rainwater.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
239 words
A refuse container cover comprising: an upper member comprising a generally rectangular platform like body having an upper surface and a lower surface, a front edge, a rear edge and two lateral side edges extending between said front and rear edges; a lower member comprising a generally rectangular platform like body having an upper surface a lower surface, a front edge, a rear edge and two lateral side edges extending between said front and rear edges; said upper and lower members being joined in coplanar juxtaposition such that the lower surface of the upper member is generally opposite the upper surface of the lower member, such joining of the upper and lower members resulting in the formation of a generally unitary refuse container cover structure; means for connecting said cover to a refuse container such that said cover will be movable (a) between an "open position" whereby access to the interior of said refuse container is permitted and (b) a "closed" position whereby access to the interior of said refuse container is substantially precluded; a plurality of first elongate ribs formed on said upper member, said first elongate ribs being in generally parallel relation to one another and oriented in a first direction; and a plurality of second elongate ribs formed on said lower member, said second elongate ribs being in generally parallel relation to one another and oriented in a second direction generally perpendicular to said first direction.
Claim 2
Dependent Claim
239 words
A refuse container cover comprising: an upper member comprising a generally rectangular platform like body having an upper surface and a lower surface, a front edge, a rear edge and two lateral side edges extending between said front and rear edges; a lower member comprising a generally rectangular platform like body having an upper surface a lower surface, a front edge, a rear edge and two lateral side edges extending between said front and rear edges; said upper and lower members being joined in coplanar juxtaposition such that the lower surface of the upper member is generally opposite the upper surface of the lower member, such joining of the upper and lower members resulting in the formation of a generally unitary refuse container cover structure; means for connecting said cover to a refuse container such that said cover will be movable (a) between an "open position" whereby access to the interior of said refuse container is permitted and (b) a "closed" position whereby access to the interior of said refuse container is substantially precluded; a plurality of first elongate ribs formed on said upper member, said first elongate ribs being in generally parallel relation to one another and oriented in a first direction; and a plurality of second elongate ribs formed on said lower member, said second elongate ribs being in generally parallel relation to one another and oriented in a second direction generally perpendicular to said first direction.
Claim 3
Dependent Claim
39 words
The refuse container cover of claim 1 wherein: said upper member further comprises a rear edge lip, a front edge lip and two lateral edge lips formed about the periphery thereof and extending in a generally downward direction therefrom.
Claim 4
Dependent Claim
39 words
The refuse container cover of claim 1 wherein: said lower member further comprises a rear edge lip, a front edge lip and two lateral edge lips formed about the periphery thereof and extending in a generally upward direction therefrom.
Claim 5
