ABSTRACT:
The invention provides a package for popping popcorn in a microwave oven including an open-topped wide mouth container in the form of a tub or bowl formed from self-supporting, i.e. stiff, microwave transparent sheet material such as stiff paper or paperboard with a flexible and expandable cover. A layer of microwave interactive susceptor material is distributed across the bottom wall of the tub to assist in popping the popcorn. Unpopped popcorn within the tub is packaged in a sealed inner compartment or container within the tub. During cooking, the flexible cover expands upwardly as the kernels pop so as to accommodate their expansion.
