Abstract
In a foamed plastic food container having an integral dish and cover, triangular pedestals are formed in the bottom wall of the dish. The height of the pedestals is equal to the stacking height of the container to prevent compacting during storage. Channels between the pedestals allow air circulation about the food in the container to prevent the food from becoming soggy.
