A unitary molded plastic bakery tray, with the end walls higher than the side walls to provide for 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 feed 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.

In a unitary molded plastic bakery tray having a rectangular bottom, a pair of opposed side walls, a pair of opposed and walls, said side walls and end walls being alternately connected to each other and to said bottom around the perimeter of said bottom to provide an upwardly opening rectangular tray, and interengaging means along said end walls for providing first and second different vertical stacking positions of like trays in a like orientation and 180 degree rotated orientation, respectively, for holding therebetween bakery products of corresponding height during storage and transportation, wherein the improvement relating to facilitating blind stacking, comprises: guide feet at the opposite ends of each of said end walls adjacent said bottom, and outwardly spaced from and separate from said interengaging means, each of said guide feet having a flat downwardly facing first portion; stacking rail means along each of said end walls spaced outwardly from and separate from said interengaging means, said stacking rail means having recesses at its opposite ends vertically aligned with said guide feet respectively for freely receiving therein said guide feet to a nesting depth of like trays sufficiently for said interengaging means to provide each of said first and second stacking positions; each said stacking rail means having a flat upwardly facing second portion extending along an entire length of said stacking rail means constructed to receive and support thereon said first portions of said guide feet of an upper said tray to maintain like orientation or 180 degree orientation of like trays vertically spaced at a height greater than said first and second stacking positions, so that when blind stacking said trays, said guide feet of an upper said tray engage said stacking rail means of a lower said tray slidably along the entire length of said stacking rail means to maintain said interengaging means spaced from each other and inoperative until said guide feet align with said interengage with said recesses; each said stacking rail means further having an inwardly facing third portion extending downwardly from said second portion and extending along the entire length of said stacking rail means; and outwardly facing means adjacent each of said guide feet and spaced downwardly from said first portion of said guide feet of an upper said tray for engaging said third portion of said stacking rail means of a lower said tray to resist lateral movement between upper and lower ones of said trays during blind stacking.
