ABSTRACT:
A tray for carrying food is disclosed as being constructed from a paperboard blank (12) having a central panel (14) of a rectangular shape with side portions (16, 17) and end portions (18, 19). A mid portion (20) is located therebetween. After assembly of the tray, side panels (22, 24) and end panels (30, 32) are folded upwardly from the central panel (14) about scoreline connections (26, 28-34, 36). A pair of horizontally extending roof panels (38, 40) overlie the central panel (14) in a horizontally spaced relationship to economize on the amount of paperboard needed for assembly of the tray and allow moisture to escape from the food. To provide rigidity to the tray and stability to a stack of multiple trays while preventing contact between food and the next highest tray in a stack, a retainer (46) extends upwardly from each corner of the central panel (14). Each retainer (46) comprises a pair of vertically spaced corners (48, 50). Located in the middle portion of the central panel (14) is a pair of interlocking tabs (52, 54) which are positionable generally perpendicularly above the central panel (14) to provide horizontal separation between food in the tray and a spaced vertical relationship between the food and the central panel of the next highest tray in a stack of trays.
