Abstract
A disposable container for heating seeds, kernels, nuts, grains, popcorn or the like items, using microwave radiation. The container comprises a can-shaped package having a floor where the items are placed and held in a clump. As the items are heated with microwave radiation, the items pop, the cover panel and/or container walls expand to form a new shape wherein the walls are inclined toward the floor. As the items pop, the unpopped items continue to be directed into a clump. Alternatively, a ferrite and metal material may be placed on the floor to enhance the heating process.
