Abstract
Microwaveable heat retentive receptacles comprising a volume for receiving a product, in heat exchange communication with a microwave absorbing material, wherein the microwave absorbing material preferably comprises polyesters. Pouches containing the microwave absorbing material are also provided which can be associated with containers to provide improved heat storage characteristics.
Claims41
A microwaveable heat retentive container comprising
- at least one portion for receiving a material;
- and
- a heat storage mass comprising a microwave absorbing material in heat exchange communication with said at least one portion, said microwave absorbing material comprising at least one polymeric resin having a melting point of at least 400.degree. F., said polymeric resin comprising repeating units having at least one of nitrogen, oxygen, and sulfur atom.
A microwaveable heat retentive container for heated foods or beverages, comprising
- (a) an outer shell,
- (b) an inner wall within said outer shell, and
- (c) a material susceptible to heating by microwave radiation, said material having a time/temperature profile such that, when from approximately 50-120 grams of said material is subjected to microwave radiation having a frequency of from approximately 2,300-2,600 MHZ, at a power of from approximately 600-1,000 W, for a period of approximately 11/4-21/2 minutes, said material is heated to a temperature in a range of approximately 170-325.degree. F.
A method of providing a heated product to a consumer or user, comprising
- (a) placing a microwaveable container in a microwave oven, said container comprising a material susceptible to heating by microwave radiation, said material having a time/temperature profile such that, when from approximately 20-120 grams of said material is subjected to microwave radiation having a frequency of from approximately 2,300-2,600 MHZ, at a power of from approximately 600-1,000 W, for a period of approximately 11/4-21/2 minutes, is heated to a temperature in the range of approximately 175.degree. F.-325.degree. F.;
- (b) adding heated product to said container, either prior or subsequent to (a);
- and
- (c) providing said container with heated product to a consumer or user.
A pouch having disposed therein a microwave absorbing material comprising polymeric acetal, acetate, cellulosic, nylon, amide, imine, ester, ether, sulfone, and/or combinations thereof.
