Abstract
Abstract A container for holding food. The container includes cylindrical side walls fixedly mounted atop a bottom wall. A externally threaded post is rotatably and removably mounted atop the bottom wall and is in meshing engagement with a horizontally extending food supporting wall which sealingly engages the interior surface of the side walls. The top end of the threaded post is reduced in configuration and keyed to receive an external tool to facilitate the rotation of the post allowing the food supporting wall to be moved upwardly maintaining the food level adjacent the top of the container as food is withdrawn therefrom. A second tool removably mounted to the top end of the post allows the post and food supporting wall to be pulled upwardly and removed from the container.
