Abstract

A storage container or bin primarily constructed of extruded fluted plastic panels. The container includes two opposed pairs of generally parallel side walls, each side wall including at least one upright extruded plastic panel disposed with the flutes extending vertically to provide vertical column strength. A stacking and reinforcing loop of metal rod is positioned in direct load-bearing engagement with the upper edges of the side walls, with the rod being fixedly secured to each side wall by securing flanges which are integral with the fluted material defining the side walls and which snugly wrap around the top rod and are fixedly secured to the respective side wall. The top stacking rod is provided with a stacking bracket adjacent each corner of the container, which bracket is positioned outwardly and upwardly of the reinforcing rod to secure and cooperate with a lower corner of a second container when the latter is vertically stacked on the top stacking rod of the first container.
