The square packing cases (1) made of cardboard can be reusedas building blocks. They have on their edges slits (5) into which clip-like connecting elements (6,7) can be inserted to connect similar types of packing cases. Each end side of the empty packing case can be reclosed cleanly and sufficiently stable by interfitting flaps and tongues (2,4). USE/ADVANTAGE - The packing cases can be made cheaply and easily out of cardboard.
