MICROWAVE FOOD SCORCH SHIELDING

摘要

A microwave container (10) which morphs from a relatively microwave transparent condition to a relatively microwave blocking condition in response to microwave irradiation. The container wall section has a plurality of discrete, unconnected microwave reflective material elements (20) initially permitting the transmission of microwave energy into the container (10) and either a microwave absorptive material (22) or a thermally responsive material active to coalesce the microwave reflective material elements (20) into a connected array or pattern to block the transmission of microwave energy from entering the container (10) after absorbing a predetermined amount of microwave energy.
