ABSTRACT:
A paperboard container is formed from a single piece with appropriate cuts, score lines and slots to become, when in the erected condition, a food container for holding hot food such as pizzas. Top and bottom panels are provided as are appropriate side panels. At the back side panel on each side thereof panels are provided whereby two opposed triangular flaps are folded back over an angle of 180.degree. to form a multi-layer construction to add to the strength. In another embodiment, front angled corners are constructed where triangular panels are created as is a generally rectangular antislide panel which, when the bottom receptacle portion is formed will be inclined inwardly within the interior of the container to form an antislide barrier.
