  • Bag utilizing a microwave susceptor and non-heated flaps
    Patent number: 5189272
    Abstract: A package for use in microwave ovens is disclosed in its preferred form of a flexible, tubular bag (18) including expandable side walls (26) interconnected between bottom and top walls (20, 22). The side walls (26) include pleats (26a, 26b, 26c, 26d) which are folded in a collapsed condition of the bag (18) and expand due to internal expansion forces generated by the popping of kernels and the creation of water vapor. The openable end (28) opposite the permanent end wall (24) of the bag (18) is formed by V-shaped adhesive strips (34, 36) located between the bottom and top walls (20, 22) and the pleats (26a, 26b, 26c, 26d).
