ABSTRACT:
The present invention is a package for selectively heating or cooling a food product of the package utilizing a temperature-changing pack disposed within an inner container. The temperature-changing pack is formed in a manner which prevents the inadvertent or premature mixing of the chemical reagents to initiate the heating or cooling reaction. Further, the temperature-changing pack is positioned within the inner container at a location where the food product comes into contact with the pack on multiple sides to maximize the heat transfer between pack and the food product. The inner container can be positioned within a reusable outer sleeve that insulates the inner container to further maximize the heat transfer between the pack and the food product.
