Abstract
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…
