Abstract

A foamed plastic food container having a dish and cover interconnected by a hinge at one end and a latching means at the other end. The hinge is biased towards the open position. The latching means comprises a male flange-like member raised above the rim of the dish and a female member on the cover. The female member comprises an outwardly protruding chamber having an indentation sloping inward toward a shelf, with a U-shaped slot being cut into the indentation and shelf. The slot is substantially wider than the width of the flange thereby permitting easy closing and opening.
