Abstract
A microwave container 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 initially permitting the transmission of microwave energy into the container and either a microwave absorptive material or a thermally responsive material active to coalesce the microwave reflective material elements into a connected array or pattern to block the transmission of microwave energy from entering the container after absorbing a predetermined amount of microwave energy.
