Abstract
Abstract The lid is made up of generally rectangular bottom and top walls having their edges sealingly connected to define a hollow interior. A bottom projecting portion is formed of smaller rectangular dimensions to fit within the upper side walls of a rubbish bin in sealing relationship. The top wall of the lid is provided with ribs having parallel central portions and thence diverging towards the corners so that utilizing the lid as a water, grass or snow sled by turning the same upside down, is inhibited. Fire retardant crystals may be incorporated in the hollow interior of the lid to aid in smothering any fire which might occur in a bin covered by the lid. Furthermore, portions of the lid are accordion pleated to permit bending about a transverse axis thereby providing a built in soft hinge preventing shattering of the lid during dumping operations.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
66 words
A rubbish bin lid of generally rectangular shape having a downwardly projecting bottom portion of smaller rectangular dimensions to fit within the upper side walls of the bin when the lid is in position, the top of the lid having rib means with portions extending in different directions to thereby inhibit use of the lid as a water, grass or snow sled if turned upside down.
Claim 2
Dependent Claim
66 words
A rubbish bin lid of generally rectangular shape having a downwardly projecting bottom portion of smaller rectangular dimensions to fit within the upper side walls of the bin when the lid is in position, the top of the lid having rib means with portions extending in different directions to thereby inhibit use of the lid as a water, grass or snow sled if turned upside down.
Claim 3
Dependent Claim
41 words
A lid according to claim 1, having a hollow interior; and fire retardant crystals filling said interior so that if a fire occurs in a bin covered by the lid, the fire retardant crystals will release to fall onto the fire.
Claim 4
Dependent Claim
19 words
A lid according to claim 1, having accordion pleated portions permitting flexing of the lid about a mid-transverse axis.
Claim 5
Dependent Claim
176 words
Rubbish bin lids for closing off a generally rectangular top opening of a rubbish bin, the upper edge of the rear wall of said rubbish bin having hinge members secured thereto, with openings for receiving a hinge rod, each of said lids including: (a) top and bottom generally rectangular walls having front, rear, left and right edges connected together to define a sealed hollow interior, (b) said bottom wall having a downwardly projecting internal channel spaced inwardly of the front, rear, left and right edges of the lid to define a rectangular shape of smaller dimensions than the remaining portions of the lid to fit in sealing relationship within one half of the rectangular top opening of the rubbish bin so that the complete rectangular opening is closed off when two of the lids are in side-by-side relationship, (c) said top wall including raised ribs having parallel central portions which diverge towards the four corners of the lid to thereby inhibit use of such lid as a water, grass or snow sled if turned upside down.
Claim 6
Dependent Claim
176 words
Rubbish bin lids for closing off a generally rectangular top opening of a rubbish bin, the upper edge of the rear wall of said rubbish bin having hinge members secured thereto, with openings for receiving a hinge rod, each of said lids including: (a) top and bottom generally rectangular walls having front, rear, left and right edges connected together to define a sealed hollow interior, (b) said bottom wall having a downwardly projecting internal channel spaced inwardly of the front, rear, left and right edges of the lid to define a rectangular shape of smaller dimensions than the remaining portions of the lid to fit in sealing relationship within one half of the rectangular top opening of the rubbish bin so that the complete rectangular opening is closed off when two of the lids are in side-by-side relationship, (c) said top wall including raised ribs having parallel central portions which diverge towards the four corners of the lid to thereby inhibit use of such lid as a water, grass or snow sled if turned upside down.
Claim 7
Dependent Claim
17 words
A lid according to claim 4, in which fire retardant crystals are provided in said hollow interior.
Claim 8
Dependent Claim

A lid according to claim 4, in which the rear corners of the lid are cut away, the rear edge of the lid having a bore running longitudinally therethrough for receiving said hinge rod, the cut away corners receiving said hinge members on the bin so that the rear edge of the lid is hinged to the bin.
Claim 9
Dependent Claim
33 words
A lid according to claim 4, in which the front edge of the lid includes left and right front corner portions having top and bottom depressions defining handle gripping areas for the lid.
Claim 10
Dependent Claim
60 words
A lid according to claim 4, in which the walls of said central portions of said raised ribs are accordion pleated and corresponding central portions of the walls of the downwardly projecting internal channel spaced inwardly of the left and right edges of the lid being similarly accordion pleated so that said rectangular lid can flex about a transverse mid-axis.
