ABSTRACT:
An expandable food such as popcorn is sealed within a pouch formed of a substantially oxygen-impermeable, flexible, synthetic high polymer film which is dimensioned so as to fit for storage and efficient cooking of the food product in an outer bowl-like protective paperboard container. The outer container and pouch can be heated in a microwave oven and the expandable pouch and food is supported and confined in the bowl of the outer container, from which the food can be consumed. The outer container is formed from a unitary blank which can be partially erected and shipped in a flat, knockdown condition to a food processor for filling with the food pouch. The base of the outer container is provided with self-locking tabs to prevent the bowl-like container from collapsing and returning to its knock-down, shipped condition after fully erected and filled with the food pouch.
