Abstract:
1. A packaging container for ready-prepared foods, comprising a container adapted to contain packed food, said container provided with a polymeric rim flange, and a lid heat-sealed to the rim flange, the rim flange being provided with three concentric ridges encompassing the perimeter of the container which define two spaces between the ridges, so that when closing the lid on the container, a gastight sealing line is formed between the lid and the rim flange, wherein the space between the concentric ridges of the rim flange is divided by transverse ridges into at least five separate, sealed compartments which are defined by the concentric ridges, the transverse ridges and the lid, and wherein the profile of the ridges is tapered upward to a pointed top to push grease aside as the lid is sealed to the dish.
