Abstract
A container (2) for heating popcorn or other types of particulate food items in a microwave oven formed from a single blank having a bottom panel (4) coated with a microwave interactive material (26) adding heat to particulate food items such as popcorn kernels and configured so that each particulate food item placed into the container (2) for heating is spaced, on average, no more than the average diameter of one such food item away from the microwave interactive layer. The container is formed for shipping in a triangular wedge shape and for expansion to a trapezoidal box shape for use within a microwave oven for heating of the particulate food items.
