ABSTRACT:
A unitary molded plastic bakery tray, with the end walls higher than the side walls to provide a 90 degree cross-nesting, and the end walls having interengaging feet and rails to provide for 180 degree oriented high stacking and like oriented low stacking. The bottom is either a flat planar surface with chamfered bottom edges or is raised so that the tray is provided with corner structure having chamfered bottom edges. Blind stacking structure is provided by an additional outer rail on each end wall and additional outer feet on each end wall for engaging the outer rail. Alternatively, blind stacking is provided by structure along each end wall having large feet and cooperating large recesses coplanar with inner small feet and cooperating inner recesses such that the large feet can span and smoothly slide over the small recesses during blind stacking. Further, trays of different series having different stacking heights can be blind stacked on one another during stacking, but include bottom and side wall structure that prevents inter cross-nesting of trays of different series.
