A folded food carton is formed from a matable, lay flat blank for retaining, transporting and serving hot food such as pizza. The blank includes an arrangement of end panels, side panels and cover panels foldable relative to a bottom panel such that, in the erected carton, the cover panels overlap and are interlocked with the side panels by means of offset locking tabs. The end panels slant upwardly and inwardly from the bottom panel to add rigidity and save material for the carton. The side panels flare upwardly and outwardly from the bottom panel and extend above the cover panels to enhance stackability and prevent shifting of stacked cartons one on top of the other. Several methods of packaging pizza in the folded carton are disclosed.

We claim: 1. A pizza box formed from an integral blank of material, the pizza box comprising: a substantially flat and rectangular bottom panel; a pair of opposed end panels and a pair of opposed, first transverse fold lines, each end panel being hingedly joined to the bottom panel along its respective first transverse fold line; a pair of opposed cover panels and a pair of opposed, second transverse fold lines, each cover panel being bingedly joined to its respective end panel along its respective second transverse fold line, each cover panel having opposed longitudinal edges, and each cover panel having a set of opposed locking tabs extending outwardly from the longitudinal edges; a pair of side panels hingedly joined to the bottom panel along a pair of opposed longitudinal fold lines, each side panel having openings for frictionally receiving the locking tabs on the cover panels; and, wherein the pizza box is foldable along the fold lines into a closed position by folding the side panels, end panels and cover panels, the cover panels being generally parallel to the bottom panel, overlapping each other and interlocking with the side panels via the locking tabs, the end panels slanting inwardly and upwardly relative to the bottom panel, the side panels slanting outwardly and upwardly relative to the bottom panel, and the side panels extending above the cover panels. 2. The pizza box of claim 1, wherein each end panel has opposed side edges diverging outwardly from ends of the first transverse fold lines to ends of the second transverse fold lines, the end panels are trapezoidal in shape. 3. The pizza box of claim 1, wherein the side edges of each side panel extend at an acute angle relative to the second transverse fold lines. 4. The pizza box of claim 1, wherein each cover panel is substantially rectangular and each locking tab is formed with a pair of outwardly diverging edges and a pair of outwardly extending, converging edges. 5. The pizza box of claim 1, wherein the locking tabs on each cover panel are offset with at least one of said locking tabs lying adjacent the second transverse fold line and the other one of said locking tabs being positioned adjacent an outer end of the cover panel. 6. The pizza box of claim 1, wherein the longitudinal fold lines lie parallel to a longitudinal axis passing through the bottom panel, and the first and second transverse lines lie parallel to each other and transverse to the longitudinal axis. 7. The pizza box of claim 1, wherein each side panel is formed with a contoured outer edge, a pair of shoulders and a pair of side edges disposed at acute angles relative to one of the longitudinal fold lines. 8. The pizza box of claim 7, wherein the contoured outer edge include a pair of spaced apart extended portions and a pair of spaced apart recesses, the extended portions and recesses on one side panel being offset relative to the extended portions and recesses on the opposite side panel. 9. The pizza box of claim 8, wherein the openings formed in each side panel lie inwardly of the extended portions. 10. The pizza box of claim 1, wherein the openings are sized to permit venting of a hot food product packaged in the pizza box. 11. The pizza box of claim 1, wherein upon folding the end panels, the side panels and the cover panels, the end panels are oriented at an acute angle relative to the bottom panel. 12. The pizza box of claim 1, wherein upon folding the end panels, the side panels and the cover panels, the side panels are oriented at an obtuse angle relative to the bottom panel. 13. The pizza box of claim 1, wherein the outwardly-slanting side panels facilitate vertical stacking of other pizza boxes one on top of the other and define guides to prevent side-to-side shifting of the other pizza boxes stacked upon the cover panels. 14. The pizza box of claim 1, wherein the end panels are substantially trapezoidal in shape. 15. The pizza box of claim 1, wherein each end panel has opposed side edges diverging outwardly from ends of the first transverse fold lines to ends of the second transverse fold lines. 16. The pizza box of claim 1, wherein each cover panel is substantially rectangular. 17. The pizza box of claim 1, wherein each locking tab is formed with a pair of outwardly diverging edges and a pair of outwardly extending, converging edges.
