ABSTRACT:
The dish vessel consists of vessel components which may in particular be used as plate or pot. On the rim the vessel components show a profile of elevations and depressions arranged in such manner that the profiles of two vessel components seated on one another and facing each other, interlock positively. The profiles are elevations having an arc-like cross-section and protruding out of the rim in longitudinal cross-sectional direction and/or depressions running into the rim, which show at one side in direction to the rim essentially perpendicular cheeks and at the remaining sides merge without steps into the rim. The surfaces of the cheeks are essentially perpendicular to a connecting line from the central point of the vessel component to the center of the cheeks.
