Claim:
A disposable food delivery container comprising substantially similar upper and lower container sections which are shaped to co-operate and define an enclosure for receiving a food item to be delivered in the container, each of said sections comprising: (a) a substantially square panel defining a base plane and having four lateral edges of substantially equal length and four corners; (b) a sidewall formed integrally with said panel and extending along each lateral edge thereof at an angle with respect to said base plane, each sidewall being of substantially constant width and defining, together with the three other sidewalls, a plane of attachment to another container section, the sidewalls being adapted to mate with the corresponding sidewalls of said other container section at said plane of attachment; (c) at least one chimney formed integrally with the said panel and extending outward from said base plane to said plane of attachment, each chimney being arranged adjacent one of the four corners and being adapted to mate with a corresponding chimney of said other container section at said plane of attachment, said chimney forming a flue for the passage of vapors and having at least one vent for allowing vapors to enter said flue from the container and dissipate in the atmosphere when vapor pressure inside the container exceeds a certain threshold above the atmospheric pressure.
