ABSTRACT:
A receptacle for delivering food in a hot condition in the form of a bag formed of insulating material having a closure defined at an end. Within the bag an insert of a high density material capable of retaining heat is located and is heated by an electric resistance heater. Prior to use, the insert mass is heated to the desired temperature and food, such as pizza, placed within the bag will stay warm due to the heat retention of the mass. A plurality of bags are stored in a heated condition so as to be ready for use as needed.
