ABSTRACT:
A container for keeping food chilled includes an integral sealed cooling fluid. The cooling fluid may be precooled in a freezer so as to maintain the food in the container in a chilled state upon a removal of the container from the freezer. Each container is manufactured from a flexible plastic bag or the like which allows an expansion of the container walls when the retained fluid is frozen. A rigid frame structure is positioned within the flexible bag to maintain the container shape. Various portions of the rigid frame structure are separated so as to facilitate container expansion during the freezing process.
