Several embodiments of an improved container are disclosed. In one embodiment, the container has a rear side wall hinge and set-up panels extending therefrom so that it can be readily assembled from an integral prescored blank. Other embodiments relate to containers with improved thermal retention properties. According to one embodiment, a container is provided with an integral polymeric layer or foil layer which includes channels or depressions for releasing steam from a hot food product carried thereon. In another embodiment, a double side wall construction is provided and with vents for passing warm air between inner and outer side walls to warm the outside surface of the inner side wall to reduce the rate at which heat is transferred from inside the container through the inner side wall.
