ABSTRACT:
A dish-shaped container is made from a folded cardboard blank sealable on both sides. The container has a rectangular bottom and four upfolded lateral panels which are connected to the container corners respectively by four triangular-shaped corner panels. A circumferential double-walled outer flange parallel to the bottom consists of first and second outer strips. The first outer strips are folded on the respective lateral panel, and the second outer strips are aligned with their cut edges towards the outer surface of the respective lateral panels. The first outer strips extend continuously over the entire periphery of the container, so that there are no breaks up to the filler area. The second outer strips are left out in the area of the corner panels. As a result of the double layer, the container comprises a reinforced outer flange and is in addition absolutely impermeable to liquids in the corner areas.
