ABSTRACT:
A flat, comparatively shallow box containing an arrangement for keeping a comparatively flat food item warm for a protracted length of time, with this box having rectangularly-shaped top and bottom members of approximately equal size. The top and bottom members are hingedly secured together by a hinge disposed along an edge common to both members, with the top member having side members disposed along each of its remaining side edges. The bottom member has a flap disposed on the edge opposite the hinge, such that closure of the box can be effected after a comparatively flat food item has been inserted into the box. The arrangement for keeping a food item warm is a sealed container for a heat-retaining substance, the container being disposed in the interior of the box, affixed to the underside of the top member. The container is thus disposed close to, or in direct contact with, the food item when the box has been closed, with the heat-retaining substance, having earlier been brought up to a selected raised temperature, serving by its proximity to keep the food item warm.
