The top side can have at least one protrusion, and the opposite side extending parallel can have at least one recess, into which a protrusion of a packaging container, for example, an identically shaped packing container, can be inserted. Such a packaging container can be produced in an economical and environmentally friendly manner, for example, by having holes punched in the top side and in the bottom side, and the protrusions and recesses attached in inserts, which are inserted into the packaging container.
