ABSTRACT:
A container, especially a food container, has straight, frustoconical side walls to give it resistance to vertical loads. A bottom is recessed upward from the bottom edge of the side wall. At the top, a flange extends radially outward. The flange is textured with grooves formed by mold machining marks to enhance bonding between the container and a flexible sheet material used to close the container. Spacers project outward from near the top of the container to permit several containers to be stacked without getting stuck to each other. The spacers have a T-shape, with the head of the T being integral with the side wall and the leg of the T forming an outwardly projecting rib.
