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. ## Claims ### Claim 1 A method of assembling a food product in container, the method comprising: pulling on a protruding end portion of a flexible envelope enclosing an intermediate food component between a first food component and a second food component while relatively simultaneously pulling in an opposite direction on the container while in a closed configuration; peeling apart a rupturable seal between at least two layers of the flexible envelope, the two layers rolling back upon themselves resulting in a ruptured flexible envelope removed from the container that remains in the closed configuration, to expose all surfaces of the intermediate food component while the intermediate food component is positioned between the first food component and the second food component; and separating a top compartment and a bottom compartment of the container to expose the first food component and the second food component with the exposed intermediate food component therebetween. ### Claim 2 (depends on 1) The method according to claim 1, further comprising winding the ruptured flexible envelope around a roller. ### Claim 3 (depends on 1) The method according to claim 1, further comprising turning a knob that contains the protruding end portion wrapped around a spool connected to the knob and the ruptured envelope is subsequently wrapped around the spool. ### Claim 4 (depends on 1) The method according to claim 1, wherein the first and second food components are a pair of bread components. ### Claim 5 (depends on 1) The method according to claim 1, wherein the food product is a sandwich. ### Claim 6 (depends on 1) The method according to claim 1, further comprising peeling away a compartment film layer extending across an opening of at least one of the top and bottom compartments and sealed to peripheral flanges thereof. ### Claim 7 (depends on 6) The method according to claim 6, further comprising peeling apart a first of an upper or lower layer of the flexible envelope from the compartment film layer. ### Claim 8 (depends on 7) The method according to claim 7, further comprising peeling apart a second of the upper or lower layers of the flexible envelope sealed to the first of the upper or lower layers of the flexible envelope. ### Claim 9 (depends on 1) The method according to claim 1, wherein pulling on the protruding end portion comprises first removing a pre-scored portion of the protruding end portion from an upper layer of the flexible envelope and then pulling on the protruding end portion to peel apart the rupturable seals. ### Claim 10 (depends on 1) The method according to claim 1, wherein the two layers of the flexible envelope are partially sealed to an intermediate layer therebetween. ### Claim 11 (depends on 10) The method according to claim 10, further comprising pulling on a pull strip attached to the intermediate layer in a direction opposite that used for pulling the protruding end portion. ### Claim 12 (depends on 1) The method according to claim 1, further comprising pulling on multiple protruding end portions each attached to a separate flexible envelope. ### Claim 13 A method of assembling a food product in a container, the method comprising: pulling on a protruding end portion of a flexible envelope enclosing an intermediate food component between a first food component and a second food component while relatively simultaneously pulling in an opposite direction on the container while in a closed configuration; peeling apart a rupturable seal between at least two layers of the flexible envelope, the two layers rolling back upon themselves resulting in a ruptured flexible envelope removed from the container that remains in the closed configuration, to expose all surfaces of the intermediate food component while positioned between the first food component and the second food component, wherein the protruding end portion extends in a secondary compartment of the container outwardly from one of the top and bottom compartments, and the ruptured envelope is pulled into the secondary compartment; and separating a top compartment and a bottom compartment of the container to expose the first food component and the second food component with the exposed intermediate food component therebetween. ### Claim 14 A package for segregating two or more components that are combined to make a product, the package comprising: an outer container having a top compartment for housing one of a product portion and a bottom compartment for housing the other of a product portion arranged in a closed configuration; an outer barrier material to keep the components separate within the outer container, the outer barrier material having an upper layer and a bottom layer and further having a rupturable seal therebetween; and a protruding end portion affixed to the outer barrier material and extending through an opening in the outer container, the outer barrier material configured to peel apart along its rupturable seal and to roll each of the upper and bottom layer of the outer barrier material back upon itself in a peeling action resulting in at least two ruptured layers and configured to be removed from the outer container that remains in the closed configuration as the protruding end portion is pulled away from the closed container to expose all surfaces of the components therein within the product portions. ### Claim 15 (depends on 14) The package according to claim 14, wherein the top compartment is for housing one of a pair of bread components and the bottom compartment is for housing the other of the pair of bread components. ### Claim 16 (depends on 14) The package according to claim 14, wherein the outer barrier material is a flexible envelope for enclosing a food component therebetween. ### Claim 17 (depends on 14) The package according to claim 14, wherein the product is a sandwich.
