Abstract
A multi level bakery tray comprising a generally rectangular bottom, and generally rectangular opposed side and end walls extending upwardly from the bottom. Two pairs of feet are disposed along a lower edge of the end walls while a pair of deep pockets and a pair of shallow pockets are disposed along an upper edge of the end walls. When multiple trays are stacked in a like orientation the shallow pockets receive the feet in a high position. When trays are oriented 180.degree. the deep pockets receive the feet in a low position. Blind stacking and unstacking is accomplished by cooperation between sloped surfaces of the feet and pockets, between the feet and the upper edges of the end walls, and between a drag rail formed beneath the end walls and a shoulder formed on the side walls. Cross nesting is also accomplished by rotating a tray 90.degree. and placing it on a lower tray in a third position lower than the high and low positions.
