ABSTRACT:
A convertible food container including two outwardly opening shells having inner walls interconnected along a common upper edge thereof for hinged movement of the shells between an open tray-forming position and a closed carton-forming position. The inner walls include integral tongue and recess lock components which are manually engageable to prevent movement of the inner walls, and hence the shells, relative to each other. A separate retainer enables a locking together of two overlying and facing containers in the open positions thereof.
