ABSTRACT:
A hot-food transporting box made of a semi-rigid material having top, back, bottom, and side panels attached to each other by fold line segments. The box also includes a multi-lamina front panel, which panel includes a first lamina extending downwardly from and attached to the top panel and a second lamina extending upwardly and attached to the bottom panel. When the box is erected, one of the front laminas is outside of, overlying, and releasably engaging the other lamina and the inside front lamina contacts the bottom or top panel to which the outside front lamina is attached, thereby retarding the sagging of the top panel of the box due to heat and moisture generated from the hot food contained therein. The inside front lamina is attached by a fold line segment to the front edge of one of the bottom and top panels. Portions of the inside front lamina and the front edge define two openings therebetween, each opening being in substantial alignment with the fold line segment and adjacent and generally perpendicular to a side panel of the box. The outside front lamina is attached by a fold line segment to the front edge of the other of the bottom and top panels and includes two tabs, each of which are folded inwardly into an opening, whereby the laminas are in releasable engagement. Inwardly directed flaps are provided on the side panels, the flaps being vertically oriented between the top and bottom panels of the box when the front laminas are in releasable engagement, so that the side panels are in a substantially 90.degree. orientation to the top and bottom panels of the box and the box remains tightly closed to prevent loss of heat from the hot food contained therein.
