A food package for segregating ingredients of a multi-component food product, such as the multiple components of a sandwich, the package comprising an outer container to house a first food component and at least one flexible envelope or barrier film layer that encloses at least one intermediate food component allowing for separation of the intermediate food component during extended periods of storage and prior to opening the product. A method for opening the package comprises applying a pulling force to an externally located protruding end portion of the envelope, such that the envelope peels apart and separates into ruptured layers that are pulled out of the food product and out of the outer container by the continual pulling force from the protruding end portion.

1. A package containing a food product and configured for segregating components of the food product, the food product having a first food component and a second food component and an intermediate food component therebetween, the package comprising: an outer container having a top compartment for the first food component and a bottom compartment for the second food component arranged in a closed configuration;a flexible envelope for enclosing the intermediate food component, the flexible envelope having an upper layer and a bottom layer with a rupturable seal therebetween; anda protruding end portion extending through an opening in the outer container and connected to a portion of the flexible envelope, the envelope layers configured to peel apart and be removed from the outer container in the closed configuration as the protruding end portion is pulled away from the container to expose all surfaces of the intermediate food component while the outer container remains in the closed configuration. 2. The package according to claim 1, wherein the upper and bottom layers of the envelope roll back upon themselves in a peeling action as the protruding end portion is pulled away from the container resulting in at least two ruptured envelope layers. 3. The package according to claim 1, wherein the protruding end portion has at least a first layer extending from the upper layer of the envelope and at least a second layer extending from the bottom layer of the envelope, where the first and second layers each has an end portion that extends across the envelope and terminates at the protruding end portion. 4. The package according to claim 3, wherein the first and second layers of the protruding end portion extend from an end of the envelope opposite the protruding end portion. 5. The package according to claim 4, wherein the first layer is an extension of its respective upper layer and the second layer is an extension of its respective lower layer, thus each comprising one continuous layer. 6. The package according to claim 4, wherein the first and second layers are not wider than the end of the envelope to which the first and second layers are affixed. 7. The package according to claim 3, wherein the outer container has peripheral flanges such that the top compartment and the bottom compartment contact each other at the peripheral flanges. 8. The package according to claim 7, wherein at least one of the top and bottom compartments has a compartment film layer extending across an opening thereat and sealed to the peripheral flanges of the top or bottom compartment. 9. The package according to claim 8, wherein the protruding end portion has a third layer extending from one side of the compartment film layer and across the opening of the top or bottom compartment, the third layer further having an end portion that extends beyond the food product and outer container into the protruding end portion. 10. The package according to claim 8, wherein a first of the upper or lower layers is at least partially sealed to the compartment film layer. 11. The package according to claim 10, wherein a second of the upper or lower layers is sealed to the first of the upper or lower layers. 12. The package according to claim 11, wherein one of the upper or lower layers is sealed to the compartment film layer about a periphery of the compartment film layer except for at least an area adjacent a third layer extending from one side of the compartment film layer and into the protruding end portion. 13. The package according to claim 12, wherein each of the upper, lower, and compartment film layers begins to peel and rupture their seals at different times. 14. The package according to claim 7, wherein at least one of the upper layer and bottom layer of the envelope is sealed to the peripheral flanges of either the top or bottom compartment, and the other of the upper layer and bottom layer is sealed to the other. 15. The package according to claim 1, wherein the protruding end portion extends between the top compartment and the bottom compartment. 16. The package according to claim 1, wherein the package further comprises an outer sleeve surrounding the outer container. 17. The package according to claim 16, wherein the protruding end portion has a tail that protrudes through the outer sleeve. 18. The package according to claim 1, wherein a second envelope encloses an additional intermediate food component and both the first and second envelopes can be opened together. 19. The package according to claim 1, wherein the protruding end portion is attached to a roller. 20. The package according to claim 19, wherein the roller has a tab that is pulled to activate the roller along one side of the package and the ruptured envelope layers are wound upon the roller. 21. The package according to claim 1, wherein the top compartment and the bottom compartment are integrally connected along a portion of a side by a hinge. 22. The package according to claim 1, wherein the protruding end portion extends in a secondary compartment of the outer container outwardly from one of the top and bottom compartments. 23. The package according to claim 22, wherein the ruptured envelope layers are pulled into the secondary compartment. 24. The package according to claim 1, wherein the protruding end portion is attached to a rotating spool mounted to the container. 25. The package according to claim 24, wherein the ruptured envelope layers are rolled up along the spool as a knob integral with the spool is turned. 26. The package according to claim 1, wherein the flexible envelope further has a middle layer between the upper and bottom layers, to which a portion of the upper and bottom layers are sealed. 27. The package according to claim 26, wherein the middle layer has an opening therein through which the intermediate food component is positioned, partially surrounded by an outer frame of the middle layer to which the upper and bottom layers are sealed. 28.
