Abstract
A microwavable container useful in the microwave heating of items, particularly foodstuffs, comprises readily separable components. An outer shell which will remain relatively cool and, therefore, capable of being handled, is flexibly hinged to an inner shell capable of sustaining high temperatures. The inner shell rotatably folds about the flexible hinge in such a way that it is arranged in a substantially spaced relation to the outer shell and is releasably secured to the outer shell. The outer shell is made of a first microwavable polymeric material. The inner shell is made of a second microwavable polymeric material which is different from the first microwavable polymeric material. A consumer may heat a food product in the inner shell of the present invention without risking contact with that inner shell when the inner shell becomes hot. After use, the components are readily separable for separate recycling processes.
