Containers

Claim 2

A container comprising rotatable support elements, a base mounted upon said support elements, a plurality of side members, a set of at least two spigots on each side member extending from a lower region thereof for removable attachment of the side member to the base, parallel crossmembers on the base, each crossmember comprising spaced elongate elements arranged one above the other and tubular elements extending between said elongate elements, said tubular elements defining a series of sets of upwardly open holes of corresponding spacing to said sets of spigots for receiving said spigots to support the side members on the base and to provide means for stowing the side members of more than one container on the base for stowage.

Claim 3

A container according to claim 1 wherein means are provided for the stacking of a second base on the said base, which means comprises recesses in the upper surface of the base positioned so as to receive therein the support elements of the said second base.

Claim 4

A container according to claim 2 wherein the said recesses are each substantially rectangular and are disposed towards the corners of the base with their longitudinal axes parallel to each other and to one side of the base.

Claim 5

A container according to claim 1 wherein the base has a pair of opposed sidewalls, the crossmembers extending substantially parallel to said sidewalls to divide the area between said walls into three discrete portions, surfacing means being provided to extend over each of the said areas, flanges provided by the crossmembers and elements projecting inwardly from the sidewalls of the base forming support means for the said surfacing means.

Claim 6

A container according to claim 1 wherein each side member is composed of a framework comprising an elongate bottom element and a plurality of upright elements secured to the bottom element, terminal portions of the upright elements projecting below the bottom element to form said spigots.

Claim 7

A container comprising, in combination, a base and a plurality of side members, rotatable support elements secured to the base to depend therefrom for movement of the container along a travel surface, said base comprising a peripheral frame, a plurality of parallel crossmembers each having a series of similarly spaced apertures and secured to the frame to divide the area within said periphery into at least three discrete portions and infill means providing a support surface over said area, openings in said infill means being vertically coincident with the rotatable support elements to receive said elements of a second, similar base stacked upon said support surface, spigots depending from each of the side members and having a spacing corresponding to the spacing of the parallel crossmembers, said spigots being removably insertable into the apertures of the crossmembers to support their side members in an upright position on the base.

Claim 8

A container comprising, in combination, a base and a plurality of side members, rotatable support elements secured to the base to depend therefrom for movement of the container along a travel surface, said base comprising a peripheral frame, a plurality of parallel crossmembers each having a series of similarly spaced apertures and secured to the frame to divide the area within said periphery into at least three discrete portions and infill means providing a support surface over said area, openings in said infill means being vertically coincident with the rotatable support elements to receive said elements of a second, similar base stacked upon said support surface, spigots depending from each of the side members and having a spacing corresponding to the spacing of the parallel crossmembers, said spigots being removably insertable into the apertures of the crossmembers to support their side members in an upright position on the base.

Claim 9

A container according to claim 6 wherein the said crossmembers each comprise bars arranged one above the other and tubular elements extending between the said bars defining the respective holes.
