Abstract
Abstract An improved spill pallet for the support of drums which contain hazardous material. The pallet provides a support surface which vertically abuts a grate upon which a number of drums are placed. Beneath the support surface is provided a number of bowl-shaped chambers which receive and contain spilled or leaked liquid. The support surface includes a peripheral rim, a series of support rails, and a central support member. The rails extend from a side wall of the pallet inwardly toward the central support member, a space or gap separating an inner terminal end of the rails and the central support member. Adjacent bowl-shaped chambers are fluidly connected by channels defined by the space between the terminal end of each rail and the central support member. The channels increase the volume available for retention and containment of liquid to at least two times the maximum volume of any drum or container placed on the pallet while the rails laterally support the side walls and help prevent deformation thereof.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
A spill pallet for supporting a plurality of fluid containing vessels, said pallet having a bottom wall and a series of vertically-oriented side walls, said bottom wall cooperating with said side walls to define an open-topped box structure, said side walls providing a peripheral rim and said bottom wall having a central support member extending upwardly therefrom, a grate mounted on said central support member and having edges supported by said peripheral rim, a series of supporting rails also extending upwardly from said bottom wall and inwardly from said side walls toward the central support member to further support said grate, the rails interconnecting the side and bottom walls and laterally stiffening the side walls, a series of fluid-receiving chambers being bounded by the rails, central support member, and side walls, terminal ends of the rails being spaced from the central support member to define fluid communication channels which fluidly interconnect adjacent chambers.
Claim 2
Dependent Claim
153 words
A spill pallet for supporting a plurality of fluid containing vessels, said pallet having a bottom wall and a series of vertically-oriented side walls, said bottom wall cooperating with said side walls to define an open-topped box structure, said side walls providing a peripheral rim and said bottom wall having a central support member extending upwardly therefrom, a grate mounted on said central support member and having edges supported by said peripheral rim, a series of supporting rails also extending upwardly from said bottom wall and inwardly from said side walls toward the central support member to further support said grate, the rails interconnecting the side and bottom walls and laterally stiffening the side walls, a series of fluid-receiving chambers being bounded by the rails, central support member, and side walls, terminal ends of the rails being spaced from the central support member to define fluid communication channels which fluidly interconnect adjacent chambers.
Claim 3
Dependent Claim
26 words
A spill pallet according to claim 1, wherein the chambers and channels have a combined volume which is at least twice that of each containment vessel.
Claim 4
Dependent Claim
27 words
A spill pallet according to claim 2, wherein the rim, central support member, and rails cooperate to define a grate-supporting surface, said grate vertically supporting the vessels.
Claim 5
Dependent Claim
36 words
A spill pallet according to claim 1, wherein the rails have an upper surface, a pair of downwardly sloping lateral surfaces, and a downwardly sloping terminal surface, said downwardly sloping surfaces merging with the bottom wall.
Claim 6
Dependent Claim
44 words
A spill pallet according to claim 4, wherein the central support member comprises an upper surface and a series of downwardly sloping lateral surfaces, the upper surfaces of the rails and the central support member cooperating with the rim to define a grate-supporting surface.
Claim 7
Dependent Claim
28 words
A spill pallet according to claim 5, wherein the Chambers and channels have a combined volume which is at least twice that of each of the containment vessels.
Claim 8
Dependent Claim
184 words
A spill pallet for supporting a plurality of fluid containing vessels, said pallet comprising a bottom wall, a series of vertically upstanding walls, and a vessel supporting grate, said bottom wall cooperating with said side walls to define an open-topped box structure which is removably covered by the grate, said side walls providing a peripheral rim and said bottom wall having a central support member extending upwardly therefrom, a series of supporting rails extending upwardly from said bottom wall and inwardly from said side walls toward the central support member, said rim, central support member and rails having generally co-planar surfaces which cooperate to vertically engage and support said grate, said rails interconnecting the side and bottom walls and laterally stiffening the side walls, wherein a series of chambers are bounded by the rails, central support member, and side walls and terminal ends of the rails are spaced from the central support member to define fluid communication channels, said channels fluidly interconnecting adjacent chambers and cooperating with said chambers to define an available volume which is at least twice that of each containment vessel.
Claim 9
Dependent Claim
184 words
A spill pallet for supporting a plurality of fluid containing vessels, said pallet comprising a bottom wall, a series of vertically upstanding walls, and a vessel supporting grate, said bottom wall cooperating with said side walls to define an open-topped box structure which is removably covered by the grate, said side walls providing a peripheral rim and said bottom wall having a central support member extending upwardly therefrom, a series of supporting rails extending upwardly from said bottom wall and inwardly from said side walls toward the central support member, said rim, central support member and rails having generally co-planar surfaces which cooperate to vertically engage and support said grate, said rails interconnecting the side and bottom walls and laterally stiffening the side walls, wherein a series of chambers are bounded by the rails, central support member, and side walls and terminal ends of the rails are spaced from the central support member to define fluid communication channels, said channels fluidly interconnecting adjacent chambers and cooperating with said chambers to define an available volume which is at least twice that of each containment vessel.
Claim 10
Dependent Claim
