Abstract: A tray for the shipment of frozen items such as frozen pies which is stackable within a box with other identical trays so that each individual frozen item is prevented from contact with any other frozen item. The tray has a bottom from which four sides extend outwardly and upwardly. The sides comprise a longitudinal pair of sides and a lateral pair of sides. A plurality of projections extend upwardly along the center line between the longitudinal sides, and two rows of protuberances, one row located on each side of the plurality of projections, extend upwardly. The plurality of projections forms a divided partition. Each protuberance is formed by a long slope which extends upwardly from the bottom of the tray towards one lateral side of the tray and by a short slope which extends almost vertically downwardly from the upper end of the long slope to the bottom of the tray. Thus, each protuberance has a resulting inverted "L" shape along its longitudinal cross-section.
