Abstract The present invention relates to a modification of a form of contemporary lunch box wherein a compartment is provided below the bottom surface of the lunch box of substantially the same area as the lunch box extending longitudinally along its entire length, having enclosed sides, a bottom, and open ends to allow easy access. The depth of said compartment may vary; however, it is generally such that it will accommodate a folded garment, such as a raincoat.
