A container for storage and cooking food comprising: a hollow body of material formed into a bottom and a perimeter wall extending upward from the bottom and thereby providing an upwardly opening tray; said wall having a lower portion and an upper portion with each portion having an inner surface and an outer surface; said wall having a ledge extending outward from the inner surface of said lower wall portion to the inner surface of said upper wall portion; said upper wall portion continuing upward from the ledge to a level where said material is turned outward to form a perimeter rim of the tray; said rim extending outward to a transition region where said material is turned downward to form a perimeter skirt of the tray encircling and spaced from said upper wall portion of said tray; a second body of material formed into a panel and a perimeter wall extending upward from the panel and then outward to form a perimeter rim of the lid and then downward to form a perimeter skirt of the lid; the perimeter wall and rim and skirt of the lid providing a downwardly-opening perimeter channel received on the rim of the tray and sealed to the tray by sealing engagement of a surface of said upper portion of the wall of the tray with a surface of said perimeter wall of said lid continuous around the perimeter of said perimeter wall of the lid; means in said panel and said ledge for connecting said lid to said tray prior to establishing said sealing engagement comprising a projection in one of said panel and said ledge and a recess in the other of said panel and said ledger; said projection and said recess being in registry when said tray rim is received in said lid channel to enable a post-in-socket relationship; said projection and recess are shaped to admit said projection into said recess when forced together, and resist separation under force directed toward removal of said projection from said recess; said projection extends downward from said panel and has stem portion proximate said panel and head portion remote from said panel; said recess extends downward into said ledge and has a narrow entrance proximate said ledge wider chamber below said entrance; whereby admission of said head through said entrance is resisted and removal of said head from said chamber is resisted.
