Abstract

An open-topped wide mouth paperboard tub (40) for popping popcorn in a microwave oven includes an upstanding side wall (12) which has a free edge (41) at the top and a lower edge (21) which rests on the oven floor. The tub (40) also includes a flat bottom wall (16) connected to the side wall (12) at an elevation spaced upwardly from its bottom edge (21) to define an air compartment between the bottom wall (16) and the oven floor. A microwave susceptor layer (48) is connected to the bottom wall (16) to assist in popping the popcorn. The lower edge (21) is uninterrupted to make possible a sealing engagement with the oven floor so that the air in the compartment becomes heated during cooking. A layer of unpopped kernels (50) rests on the bottom wall (16) in heat conductive relationship with the susceptor (48). A flexible cover (12') which is sealed to the free edge (41) expands upwardly as the kernels (50) pop to accommodate their expansion.
