Abstract
Abstract Enclosed herein is a container cover for use in conjunction with a refuse container characterized by a polymeric body formed into a substantially planar sheet. The sheet has a first side having a plurality of longitudinally extended ribs spanning the greater portion length of the sheet and a second side having a plurality of latitudinally transverse ribs spanning the greater portion of the width of the sheet. Support brace receiving bosses are provided to secure the cover in a fixed open position during refuse loading. The upper surface of the container cover is characterized by an arcuate span lengthwise and width wise, while the plane of the underside of the cover is characterized by a longitudinally arcuate span. In this manner, additional stiffness and durability is built into the refuse container cover.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
120 words
A container cover for use in conjunction with a refuse container, comprising: a plastic body formed into a double wall substantially planar sheet bounded by a substantially continuous peripheral edge; said sheet defined by a first side having a plurality of longitudinally extending ribs spanning the greater part of the length of said sheet; and, a second side having a plurality of transverse ribs spanning the greater part of the width of the said sheet, with said first and second sides being spaced apart from one another; and integral hinge means for pivotally securing side cover to the refuse container; whereby, a light-weight, durable, flexible and resilient container cover is pivotally securing to the top of a commercial trash container.
Claim 2
Dependent Claim
120 words
A container cover for use in conjunction with a refuse container, comprising: a plastic body formed into a double wall substantially planar sheet bounded by a substantially continuous peripheral edge; said sheet defined by a first side having a plurality of longitudinally extending ribs spanning the greater part of the length of said sheet; and, a second side having a plurality of transverse ribs spanning the greater part of the width of the said sheet, with said first and second sides being spaced apart from one another; and integral hinge means for pivotally securing side cover to the refuse container; whereby, a light-weight, durable, flexible and resilient container cover is pivotally securing to the top of a commercial trash container.
Claim 3
Dependent Claim
78 words
A container cover as in claim 1, wherein: said planar sheet defines a bracket receiving reinforced recess; said reinforced recess being provided to receive a support bracket which is pivotally secured at one end to the side of said refuse container; said reinforced recess positioned near said hinge means and said bracket; whereby said cover may be fixed at an open angle to maintain a partially opened lid without significant bending or drooping even under high temperature conditions.
Claim 4
Dependent Claim
40 words
A container cover as in claim 1, wherein said hinge means comprises: a steel reinforcing tube integrally positioned along an edge of said sheet; said tube positioned to receive a hinge rod; whereby, pivotal movement of said cover is achieved.
Claim 5
Dependent Claim
39 words
The container cover as in claim 1, wherein: said longitudinally extending ribs spanning the greater part of the length of said sheet are positioned orthogonal to said transverse ribs spanning the greater part of the width of said sheet.
Claim 6
Dependent Claim
36 words
The container cover as in claim 1, wherein: the plastic body is molded to provide a substantially hollow planar assembly having longitudinally extending ribs on said first side and transverse extending ribs on said second side.
Claim 7
Dependent Claim
35 words
The container cover as in claim 1, wherein: said longitudinally extending ribs have an arcuate span along their length and side to side; and, said latitudinally extending ribs have an arcuate span side to side.
Claim 8
Dependent Claim
14 words
The container cover of claim 1, wherein: said cover is formed of cross-linked polyethylene.
Claim 9
Dependent Claim
54 words
A cover for commercial trash containers as defined in claim 1 wherein said cover has a raised upper portion and a recessed lower portion having dimensions which match but which are slightly larger than said raised upper portion, whereby a plurality of said lids will nest and stack when piled on top of one-another.
Claim 10
Dependent Claim
56 words
A plastic lid for commercial trash bins, comprising: an upper first sheet surface and a lower second sheet surface; said first and second sheet surfaces each having ridges formed in substantially opposite directions; whereby, a composite lid formed by said first and second sheet surfaces has increased strength and resistance to bending, both front-to-back and side-to-side.
Claim 11
Dependent Claim
56 words
A plastic lid for commercial trash bins, comprising: an upper first sheet surface and a lower second sheet surface; said first and second sheet surfaces each having ridges formed in substantially opposite directions; whereby, a composite lid formed by said first and second sheet surfaces has increased strength and resistance to bending, both front-to-back and side-to-side.
Claim 12
Dependent Claim
25 words
The plastic lid of claim 9, wherein: front-to-back ridges are formed on the first sheet surface which are slightly arcuate and serve to facilitate drainage.
Claim 13
Dependent Claim

The plastic lid of claim 9, wherein: the ridges formed in opposite directions are orthogonal to each other.
Claim 14
Dependent Claim
54 words
A cover for commercial trash containers as defined in claim 9 wherein said cover has a raised upper portion and a recessed lower portion having dimensions which match but which are slightly larger than said raised upper portion, whereby a plurality of said lids will nest and stack when piled on top of one-another.
Claim 15
Dependent Claim
17 words
A container cover as defined in claim 9, wherein said cover is a hollow rotationally molded product.
Claim 16
Dependent Claim
76 words
A container cover for commercial trash bins, comprising: an upper first side having a plurality of longitudinally extending ribs spanning the greater portion of length of said cover, said upper first side being substantially convex; a lower side having a plurality of latitudinally extending ribs spanning the width of said lid, said lower side being substantially concave; and, a molded reinforced hinge for receiving a rod for pivotally attaching said cover to a commercial trash bin.
Claim 17
Dependent Claim
76 words
A container cover for commercial trash bins, comprising: an upper first side having a plurality of longitudinally extending ribs spanning the greater portion of length of said cover, said upper first side being substantially convex; a lower side having a plurality of latitudinally extending ribs spanning the width of said lid, said lower side being substantially concave; and, a molded reinforced hinge for receiving a rod for pivotally attaching said cover to a commercial trash bin.
Claim 18
Dependent Claim
54 words
A cover for commercial trash containers as defined in claim 14 wherein said cover has a raised upper portion and a recessed lower portion having dimensions which match but which are slightly larger than said raised upper portion, whereby a plurality of said lids will nest and stack when piled on top of one-another.
Claim 19
Dependent Claim
