ABSTRACT:
A food container formed from a foldable blank of corrugated cardboard into a box-like configuration for transport of a food product therein such as pizza. The food container includes upper and lower portions which are swingable towards and away from one another to define closed and open configurations of the box. The lower portion of the container has a generally planar bottom wall from which a pair of elongate side walls and front and rear side walls fold upwardly and angle outwardly relative thereto. The angled orientation of the side walls permits nesting of partially assembled containers one within the other in a vertically stacked configuration. The upper portion of the container includes a generally planar top wall from which a pair of side walls fold downwardly along side edges thereof. Each of these side walls includes an outwardly projecting locking tab which engages within a correspondingly located rear slot formed in the lower portion. The upper portion further includes a frontwardly oriented side wall which folds downwardly from the top wall, which side wall includes a pair of additional locking tabs projecting outwardly from each end thereof, which locking tabs engage with a front pair of slots formed in the lower portion.
