Compartmented heating and cooling chest

A portable, insulated carrying chest for storing, carrying, and maintaining the temperature of both heated and chilled contents, comprising:

• a receptacle having a floor and upright exterior walls;
• at least two insulated compartments defining open chambers therewithin, prevented from fluid communication with one another and with ambient air, said insulated compartments including separate substantially planar horizontal covers, whereby one of said insulated compartments is isolated from another said insulated compartment when open, and also isolated from ambient air;
• a chilled heat absorbing medium located inside a first one of said at least two insulated compartments;
• a heated heat emitting medium located in another one of said at least two insulated compartments wherein said heat emitting medium is sealed in an airtight bag and spontaneously emits heat upon exposure to air by perforating said bag;
• at least one carrier for holding said heat emitting medium, comprising two perforated carrier walls sandwiching said heat emitting medium bag and means for removably suspending said carrier from cooperating slots formed in opposing walls inside a second one of said at least two insulated compartments of said carrying chest wherein;
• said insulated compartments, said heat absorbing means and said heat emitting means defined means to simultaneously maintain a temperature inside said first compartment at a level substantially below a temperature of said ambient air surrounding said chest and a temperature inside said second compartment at a temperature substantially above said temperature of said ambient air and the freedom from any external energy source assures complete portability.
