Abstract: The present invention relates to a method for forming a package by moulding a cardboard blank in such a manner that a margin area (2) of the blank, surrounding a middle portion (1) of the blank, is bent upwards to form side walls of the package while the middle portion forms a bottom of the package. The cardboard blank prior to moulding is provided with at least one area (4) of reduced bending stiffness being located in a transition zone (3) between the side walls and the bottom. The package is moulded from the blank so that the at least one area (4) of reduced bending stiffness is located in the bended areas between the side walls and the bottom and extend in the running direction of the bend. The invention further relates to a package and a package blank that can be used for forming said package.

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.
