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.

A deformable container comprising a bottom dish and a top cover having a connecting hinge at one end and a latching means having a male portion and a female portion at the other end, wherein: said bottom dish comprises a base wall and side walls outwardly inclined from said base wall and terminating at their edges remote from said base wall in a flared first rim; at one end of said dish said first rim being integrally molded to said hinge and at the opposite end said first rim terminating at and being integrally molded to said male portion of said latching means; said male portion of said latching means comprises a central segment lying in a plane substantially parallel to said base and displaced above the level of said first rim in a direction away from said base; said central segment being connected to the top of the side wall of the bottom dish; and supporting segments interconnecting said central segment and said first rim on each side of said central segment; said supporting segments also being connected to the top edge of said side wall; whereby the side wall, central segment, supporting segments and first rim form a relatively rigid structure free of hinge-like connections between the side wall and the male portion of the latching means; said top cover comprises a top wall and side walls outwardly inclined from said top wall and terminating in a flared second rim; at one end of said cover said second rim being integrally molded to said hinge and at the opposite end said second rim terminating at and being integrally molded to said female portion of said latching means; said female portion of said latching means comprises an outwardly protruding chamber formed at least in part in the cover side wall and disposed on the side of said second rim toward said top wall; a shelf defining the end of the protruding chamber nearer the top wall and connected to the cover side wall, said shelf being substantially parallel to said top wall; an inwardly protruding indentation formed in said chamber, said indentation angling from the outer edge of said chamber toward the inner portion of said shelf; and a U-shaped slot cut into said chamber with the outer circumference of the U cut into said shelf and the inner circumference of the U cut into the inwardly protruding indentation; said inner and outer circumferences of the slot being displaced from one another in a direction parallel to the plane of the shelf whereby the slot may be formed by a cutting tool moving perpendicular to the plane of said shelf; and said hinge, said botton dish, said top cover, and said male and female portions of said latching means being constructed and arranged so that as said cover is rotated about said hinge toward the closed position said central segment rides on said inwardly sloping indentation until it snaps into said slot.
