Abstract:
A box and a wheeled dolly component system comprising: a box having a pair of opposed side walls, a pair of opposed end walls, a horizontal bottom wall, and a top opening for receiving articles to be transported, at least two of said walls having an upper planar wall portion and a lower planar wall portion, each upper planar wall portion extending outwardly beyond each lower planar wall portion and being interconnected to form an edge portion extending substantially along an entire length of each respective wall, each edge portion of at least one of said pairs of opposed side walls and end walls comprising at least one downwardly facing planar surface which is parallel to the bottom wall of the box, at least one of said upper planar wall portions comprising a plurality of recessed portions extending upwardly from said downwardly facing planar surface; and a wheeled dolly having support surfaces for supporting said box consisting of a pair of opposed vertically oriented side support walls and a pair of opposed vertically oriented end support walls which form an opening in said wheeled dolly extending through the entire wheeled dolly, said side and end support walls having upper edge portions extending substantially along their entire lengths with the edge portions of at least one pair of such side and end support walls having at least one complementary upwardly facing planar surface which mates with the corresponding downwardly facing planar surface on the wall of the box when the box is being supported by the dolly, at least one of said edge portions comprising a plurality of upwardly extending projections, one of said projections having a greater vertical height than the remaining plurality of projections for preventing a planar member from being supported in a horizontal orientation on the dolly, and wherein said dolly further includes a plurality of wheel housings each of which projects a sufficient distance outwardly from each of the opposed walls about the exterior of said dolly to provide clearance for the insertion of a wheel in each respective wheel housing such that said wheel housings permit a plurality of wheeled dollies to be stacked one upon another.
