Container assembly consisting of a tray-shaped bottom part (3) and a tray-shaped lid (2). The closure effective between them consists of a U-shaped part (10, 12) that is fixed to the lid and a straight end edge that is fixed to the bottom part. The straight end edge is inserted in the U-shaped part to produce closure. The U-shaped part and/or straight end edge are locally provided with elevations (22, 23) to provide a continuous connection between the interior and the exterior of the assembly, the dimensions of the connection being accurately defined. |
