A package for use in a microwave oven is sealed at both of its ends. The package is transversely folded intermediate its ends to form a first compartment in which one food product is contained, such as kernels of corn to be popped, and a second compartment in which is contained a second food product, such as a flavoring component or additive. The fold in one face wall extends inwardly and the fold in the other face wall extends outwardly, the two folds being nested together. The sides of the package are pleated. Whereas the transverse sections forming the folds are secured together in one instance and secured to the other in another instance, the pleats of the other face wall are secured to the fold in the one face wall by adhesive spots. A sufficient build-up of pressure in the compartment containing the kernels to be popped will cause the folded configuration to at least partially unfold, thereby providing communication between the compartment in which the kernels are contained and the compartment in which the flavoring component or additive is contained. The configuration of the fold is such that a dam remains which prevents any undesired flow of additive from the compartment in which it is contained into the compartment in which the corn kernels are initially contained. By grasping the closed end adjacent the second compartment and allowing the package to assume a vertical condition, the user can shake the package, simply moving the closed end up and down so that the additive in the second compartment gravitationally flows downwardly into the first compartment where it is dispersed throughout the popped product.

A package for use in a microwave oven comprising a tubular bag of flexible sheet material including first and second face walls, said tubular bag being closed at its ends, a transverse fold intermediate said ends releasably retaining said first and second face walls together in an inverted U-shaped configuration to form a partition which separates the bag into first and second compartments, said fold preventing communication between said compartments, at least a portion of said first compartment being transparent to microwave energy, a microwave absorber/heat generator element in the package associated with at least said first compartment, a first food product contained in said first compartment to be heated to a high temperature, and a different food product contained in said second compartment to be heated to a lower temperature and then to be added to said first product, said second product being flowable when heated, said transverse fold forming said partition releasing said first and second face walls causing the fold to separate so that the upper face wall comes away from the lower face wall during microwave cooking due to the internal pressure created within the bag during said cooking, when the package is laid out horizontally so that said first product can expand into said second compartment yet the lower face wall maintaining its folded shape sufficient to function as a dam to prevent the flow of said second product in the second compartment into said first compartment during heating and when the bag is maintained horizontal but allowing for flow of said second product into said first compartment when the package is oriented vertically and the gap between the face walls is expanded.
