Abstract
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, knock-down 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.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
229 words
A quick-opening, non-metallic container for housing an expandable food pouch in a non-expanded and in an expanded condition comprising: a base portion having a bottom support panel of regular polygonal shape bisected by a scoreline and adapted to be folded about said scoreline, upwardly and outwardly extending side wall panels connected to preselected ones of the edges of said polygonally shaped bottom support panel, each one of said side wall panels being connected to the adjacent one thereof to form with said bottom support panel a bowl when said bottom support panel is unfolded about said scoreline, said bowl being adapted to receive an expandable food pouch in a stored condition, a plurality of overlapped, separate top panels, each top panel having an edge resiliently and foldably connected to one of said side panels, and means connected to said bottom support panel extending between said bottom support panel and said side wall panels for locking said bottom support panel in a substantially horizontal plane relative to said sidewalls, said locking means including a pair of abutment tabs foldably connected to opposed sides of said bottom support panel adapted to be placed in contact with the interior of a pair of adjacent sidewall panels, and a V-shaped locking tab cut from at least one of said pair of abutment tabs extending at least partially beneath one of said sidewall panels.
