A container for a food product, such as pizza, has a bottom, two side walls, a rear wall and a front wall, all formed from a single blank of paperboard. A lid folds over the rear wall. Lid flaps depend from the lid on each side for insertion on an interior side of each of the side walls. The lid flaps have a retaining portion of greater height and a recessed portion. Diagonal corner walls extend between the side walls and the front wall. A slot locates in each corner wall for receiving a tab depending from the lid to lock the lid in a closed position. The slot and tabs have lower edge that incline in opposite directions.
