Abstract
Abstract A molded single service food container adapted to permit eating the food directly from the container, comprising a formed tray portion generally wedge shaped having a planar top edge which is angularly disposed with respect to the bottom. A cover portion having substantially similar characteristics may be hinged to the tray by a continuous hinged member. Both tray and cover are preferably thermoformed plastic, either vacuum or pressure formed. The shallow end is provided with food elevating means to prevent food which overhangs the shallow end from contacting an unsanitary surface. CONTINUATION-IN-PART
