Microwave popcorn package
First Claim
1. A package for in situ microwave popping of popcorn, said package comprising:
- (a) a paperboard carton comprising a top wall, a bottom wall, and side and end walls foldably interconnecting said top and bottom walls, said top and bottom walls being parallel to each other;
(b) said top wall including a removable portion formed therein, and a plurality of constraining portions in said top wall with said constraining portions at least partially bounding said removable portion, whereby removal of said removable portion from said carton is operable to form an opening in said top wall which opening is at least partially bounded by said constraining portions; and
(c) a sealed flexible pouch containing popcorn kernels to be popped in said package, said kernels being substantially centrally located in said pouch, said pouch being disposed in said carton in a folded condition wherein a first pair of opposed edges of said pouch are folded into overlapping relationship with each other above the enclosed popcorn kernels and a second pair of opposed edges of said pouch are folded into overlapping relationship with each other above said first pair and said enclosed popcorn kernels so as to impart to said folded pouch a size which closely conforms to the size of said carton, said pouch being disposed in said carton with said second pair of overlapping edges of said pouch being disposed immediately inwardly of said removable portion of said carton and with a portion of said popcorn kernels being disposed in parts of said pouch positioned between said bottom wall and said top wall constraining portions sufficient such that popped pieces of popcorn within said pouch will operate to wedge said parts of said pouch between said constraining portions of said carton top wall and corresponding portions of said bottom wall to lock said pouch to said carton while said overlapping edges of said pouch are free to move outwardly of said carton through said opening to expand the pouch to receive popped kernels of the popcorn.

Abstract
The package allows the popping of popcorn in situ within a pouch contained in a carton. The carton has a tear-away portion in its top panel which is removed when the package is put into the microwave oven. The pouch is folded in the carton so that the edges of the folded pouch are disposed beneath the opening formed by removal of the tear-away portion. The top panel of the carton includes marginal constraining portions bounding the opening which constrain the pouch once the popcorn has commenced popping. The basal portion of the pouch is thus held in the carton while the remainder of the pouch expands through the opening during popping. The carton is provided with feet which elevate the bottom panel of the carton in the microwave oven to minimize scorching of the bottom panel during popping.
