Abstract

See full text

A stackable tray for paper stock, drawings sheets, or the like comprising a bottom panel, opposing side walls extending upwardly from the bottom panel along the side edges thereof, and front and walls extending upwardly from the bottom panel along the front and rear edges thereof. The front wall is comprised of a pair of spaced apart front wall segments defining an opening traversing substantially the length of the tray. The walls define a top ledge extending upwardly and a bottom ledge extending downwardly. The top and bottom ledges are sized and positioned so that the top ledge of one tray is received within and bounded by the bottom ledge of a like tray when the trays are stacked, or vice versa. The bottom panel defines a plurality of recesses aligned in rows and columns. A cross brace traverses each tray and is received within a recess formed in the underside of the bottom panel. The walls and bottom panel are molded to form inner and outer shell segments with a hollow cavity therebetween, with the lower shell segment of each square recess extending upwardly adjacent to the upper shell segment of the bottom panel. The trays may be stacked with the openings facing the same or opposing directions relative to one another. Each tray will support a large weight of paper stock without flexing or bending to obstruct the opening of a tray lower in the column, and without breaking or becoming dislodged.
