Abstract
Abstract An insulated chest for the storage and transportation of hot and cold foods to be carried as a backpack is disclosed. The chest has a hollow box-like body having four side walls, a bottom wall and top wall. There is a first opening in one of the side walls and a door adapted to be opened and closed is attached to the body so that it seals the opening when in a closed position. In the interior of the chest a removable divider is detachably connected to the side walls below the first opening. The chest can also have a second divider sealingly connected to the side walls in the interior of the chest, defining a liquid-holding chamber. A spigot mounted on a side wall extends through the side wall into the liquid-holding chamber. One of the walls has a second opening to the liquid-holding chamber, through which the chamber can be filled with liquid, and there are means for sealing the second opening.
