Abstract
Abstract A pallet used for the storage and transporting of containers such as beer kegs and the like. The pallet is formed as a unitary plastic member in a rotational molding operation and includes a pair of spaced outer skins which are internally connected by a plurality of properly spaced webs for internal strength. The skins also have a plurality of strategically located apertures which extend through each of the skins and are formed by webs which extend between the skins. A pair of reinforcing members formed of wood, metal or the like extend longitudinally through the pallet and engage the interiorly presented surfaces of a portion of the skins. The pallet has a plurality of downwardly extending shoulders for engagement with containers on its underface and is also provided with supporting areas on its upwardly presented surface for removably supporting a plurality of like containers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
A load-carrying pallet formed substantially of a plastic material as a substantially integral structure and comprising a first wall adapted to receive load-bearing structures thereon and having an interiorly presented surface, a second wall disposed beneath said first wall and having an interiorly presented surface spaced from the interiorly presented surface of said first wall, peripheral wall-forming means operatively associated with said first and second walls and providing operative connection between said first and second wall, at least one weblike element extending between said first and second walls to integrally join said first and second walls, and at least one rigid nonplastic reinforcing member extending between said first and second walls and snugly engaging the interiorly presented surfaces of said first and second walls.
Claim 2
Dependent Claim
124 words
A load-carrying pallet formed substantially of a plastic material as a substantially integral structure and comprising a first wall adapted to receive load-bearing structures thereon and having an interiorly presented surface, a second wall disposed beneath said first wall and having an interiorly presented surface spaced from the interiorly presented surface of said first wall, peripheral wall-forming means operatively associated with said first and second walls and providing operative connection between said first and second wall, at least one weblike element extending between said first and second walls to integrally join said first and second walls, and at least one rigid nonplastic reinforcing member extending between said first and second walls and snugly engaging the interiorly presented surfaces of said first and second walls.
Claim 3
Dependent Claim
52 words
The pallet of claim 1 further characterized in that a plurality of spaced reinforcing members extend betweEn said first and second walls and snugly engage the interiorly presented surfaces of said first and second walls, said reinforcing members being formed of a rigid structural material and being essentially noncircular in cross section.
Claim 4
Dependent Claim
156 words
A load-carrying pallet formed substantially of a plastic material as a substantially integral structure and comprising a first wall adapted to receive load-bearing structures thereon and having an interiorly presented surface, a second wall disposed beneath said first wall and having an interiorly presented surface spaced from the interiorly presented surface of said first wall, first and second enlarged sections operatively associated with said first and second walls in proximate relation to a pair of margins of said walls and providing operative attachment between said first and second walls, an intermediate section located between said first and second sections, floor-engageable elements operatively associated with said first and second sections, at least one weblike element extending between said first and second walls to integrally join said first and second walls, and at least one nonplastic reinforcing member extending between said first and second walls and snugly engaging the interiorly presented surfaces of said first and second walls.
Claim 5
Dependent Claim
156 words
A load-carrying pallet formed substantially of a plastic material as a substantially integral structure and comprising a first wall adapted to receive load-bearing structures thereon and having an interiorly presented surface, a second wall disposed beneath said first wall and having an interiorly presented surface spaced from the interiorly presented surface of said first wall, first and second enlarged sections operatively associated with said first and second walls in proximate relation to a pair of margins of said walls and providing operative attachment between said first and second walls, an intermediate section located between said first and second sections, floor-engageable elements operatively associated with said first and second sections, at least one weblike element extending between said first and second walls to integrally join said first and second walls, and at least one nonplastic reinforcing member extending between said first and second walls and snugly engaging the interiorly presented surfaces of said first and second walls.
Claim 6
Dependent Claim
74 words
The pallet of claim 3 further characterized in that load-bearing shoulders are operatively associated with said first and second sections, and cooperating load-bearing shoulders are operatively associated with said intermediate section and cooperating with the load bearing shoulders associated with said first and second sections so that the shoulders of said first and second sections and said intermediate section support the load of said pallet when the pallet is disposed on a load-bearing structure.
Claim 7
Dependent Claim
80 words
The pallet of claim 3 further characterized in that a plurality of spaced reinforcing members extend between said first and second walls for a distance approximately equal to the distance between two opposed margins of the first and second walls and snugly engage the interiorly presented surfaces of said first and second walls, said reinforcing members being formed of materials selected from the class consisting of wood and metal, said reinforcing members being rigid and essentially noncircular in cross section.
Claim 8
Dependent Claim
235 words
A load-carrying pallet formed substantially of a plastic material as a substantially integral structure and comprising a first wall adapted to receive load-bearing structures thereon and having an interiorly presented surface, a second wall disposed beneath said first wall and having an interiorly presented surface spaced from the interiorly presented surface of said first wall first and second enlarged sections located along two opposed margins of said first and second walls and providing operative attachment between said first and second walls, an intermediate section located approximately midway between said first and second enlarged sections, floor-engageable elements integrally formed with said first and second sections and said intermediate section, load-bearing shoulders operatively associated with said first and second sections, a plurality of load-bearing shoulders operatively associated with said intermediate section and cooperating with the load-bearing shoulders on said first and second sections, at least one aperture extending through said first wall and said intermediate section, a web surrounding said aperture and extending between said first wall and said intermediate section, and a plurality of spaced rigid reinforcing members extending between said first and second walls and snugly engaging a portion of the interiorly presented surfaces of said walls, said members extending for a distance approximately equal to the distance between two opposed margins of the first and second walls, said reinforcing members being formed of a rigid structural material and being essentially noncircular in cross section.
Claim 9
Dependent Claim
