Abstract: The invention relates to a package for ready-prepared foods, which comprises a dish (1) containing packed food that has been cooked in the dish, and a lid heat- sealed to the rim flange (2) of the dish. Upon cooking grease lands onto the rim flange, the detriment of which caused to the sealing has in the invention been prevented by providing the rim flange with elevated ridges (3, 4) so that, upon closing the dish, a gastight sealing line is formed between the lid and the ridges. According to the invention the rim flange has two or more concentric longitudinal ridges (3) circulating the dish and transverse ridges (4), by means of which the space between two longitudinal ridges (3) has been divided into at least five compartments for diminishing the possibility of sealing leakages. In practice there can be considerably more compartments, suitably 10-200. The dish can be made of polymer- coated cardboard, the rim flange of injection-moulded plastics and the lid of polymer-coated paper so that a closure making possible the pulling off of the lid is produced during heat-sealing.
