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.
