Abstract
A lower receptacle section with a flat base and upwardly sloping side walls mates with an upper cover section a flat top and downwardly sloping side walls. A hinge connects portion of the lower section lip to a portion of the upper cover section lip. Integrally formed v-shaped ribs in the flat base and the flat top provide structural strength, and pre-formed creases (or fold lines) facilitate folding of the food box for disposal.
