Abstract
Abstract A light-weight, one piece maintenance free, weather-resistant, stiff, warp and sag-proof planar molded plastics material cover or lid for containers has embossed portions defining hinge structure along the rear edge thereof, spaced transverse ribs across the width thereof and a longitudinal rib adjacent the front edge thereof merged into the transverse ribs. A peripheral lip is also formed around at least the front and sides. The lid or cover is substantially uniform in thickness, the embossed ribs are preferably U-shaped in cross section, and the embossed hinged structure has apertures forming bearings for a hinge rod.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
134 words
In combination with a container having an open top section with hinge rod brackets and a hinge rod at the back edge thereof, a one piece molded plastics material lid for said open section comprising a substantially planar sheet of substantially uniform thickness with a dependent peripheral lip along the front and sides of the sheet, said sheet having U-shaped hinge portions extending along the rear edge thereof with end wall portions having bores adapted to receive the hinge rod carried by the brackets of the container, and a plurality of embossments in said sheet extending transversely and longitudinally providing reinforcing ribs including at least one longitudinal rib spanning the sheet near the front edge thereof and a plurality of transverse ribs spanning the sheet between the longitudinal rib and the U-shaped hinge portions.
Claim 2
Dependent Claim
134 words
In combination with a container having an open top section with hinge rod brackets and a hinge rod at the back edge thereof, a one piece molded plastics material lid for said open section comprising a substantially planar sheet of substantially uniform thickness with a dependent peripheral lip along the front and sides of the sheet, said sheet having U-shaped hinge portions extending along the rear edge thereof with end wall portions having bores adapted to receive the hinge rod carried by the brackets of the container, and a plurality of embossments in said sheet extending transversely and longitudinally providing reinforcing ribs including at least one longitudinal rib spanning the sheet near the front edge thereof and a plurality of transverse ribs spanning the sheet between the longitudinal rib and the U-shaped hinge portions.
Claim 3
Dependent Claim
113 words
A lid or cover for open top containers comprising a single embossed plastics material sheet of uniform thickness having front, side and back edges, a U-shaped embossment along the back edge adapted to receive a hinge rod therethrough to connect the sheet with a container, a plurality of spaced parallel transverse embossments in said sheet extending from adjacent said U-shaped embossment into closely spaced relation with the front edge of the sheet, a longitudinal embossment extending longitudinally across the sheet closely adjacent the front edge thereof and intersecting said transverse embossments, said transverse and longitudinal embossments providing reinforcing ribs holding the sheet against distortion, and an integral dependent peripheral lip on the sheet.
Claim 4
Dependent Claim
113 words
A lid or cover for open top containers comprising a single embossed plastics material sheet of uniform thickness having front, side and back edges, a U-shaped embossment along the back edge adapted to receive a hinge rod therethrough to connect the sheet with a container, a plurality of spaced parallel transverse embossments in said sheet extending from adjacent said U-shaped embossment into closely spaced relation with the front edge of the sheet, a longitudinal embossment extending longitudinally across the sheet closely adjacent the front edge thereof and intersecting said transverse embossments, said transverse and longitudinal embossments providing reinforcing ribs holding the sheet against distortion, and an integral dependent peripheral lip on the sheet.
Claim 5
Dependent Claim
14 words
The lid of claim 1 wherein the plastics material is a cross linked polyethylene.
Claim 6
Dependent Claim
29 words
The lid of claim 1 wherein the sheet has a thickness of from 1/8 to 1/4 inches and the embossments have a depth of from 1/2 to 1 inch.
Claim 7
Dependent Claim
12 words
The lid of claim 1 wherein the transverse and longitudinal embossments intersect.
Claim 8
Dependent Claim
25 words
The lid of claim 5 wherein the intersections are near the front edge of the sheet rearwardly of the front ends of the transverse embossments.
Claim 9
Dependent Claim
20 words
The lid of claim 1 wherein the transverse ribs are in spaced parallel relation across the length of the sheet.
Claim 10
Dependent Claim
27 words
The lid or cover of claim 2 wherein the U-shaped embossment is segmented and each segment has apertured end walls providing bearings riding on the hinge rod.
Claim 11
Dependent Claim
28 words
The lid or cover of claim 2 wherein the embossments are positioned to accommodate mounting of the sheet with either face thereof providing the top of the cover.
Claim 12
Dependent Claim
19 words
The lid or cover of claim 2 wherein the ribs are raised from the top face of the sheet.
Claim 13
Dependent Claim
19 words
The lid or cover of claim 2 wherein the ribs are depressed from the top face of the sheet.
Claim 14
Dependent Claim
17 words
The lid or cover of claim 2 wherein the U-shaped embossment is deeper than the rib embossments.
