Dual compartment sandwich package

A dual compartment sandwich package fabricated of foamed polystyrene or the like and adapted to retain therein in appealing and acceptable form a sandwich including a hot meat portion, such as a hamburger, and a cool trimmings portion, such as lettuce and tomato. The package includes a base and cover having central rib means for rigidifying the package and preventing bending about the longitudinal and transverse axes thereof. There are four cooperating slots and tabs for temporary or secure locking of the cover to the base, which latter condition also forms an external seal to prevent heat exchange with the ambient atmosphere, while the central rib means form an internal barrier to prevent transfer of air and heat between the two compartments. A method of packaging a hot meat portion-cool trimmings portion sandwich, such as a lettuce and tomato hamburger sandwich for dispensing and final assembly by a customer in such a dual compartment package is also disclosed.
