Abstract: A leakproof and liquid-tight packaging box of corrugated board, which box is erected mechanically using glueing as an aid. What is essential in the invention is that the corner surfaces of the structurally strong, torsionally rigid, leakproof and liquid-tight packaging box stackable one on top of another are folded and glued to the outer surface of the vertical surface of the short side. In addition, it comprises an inward-formed cone structure of the vertical surface of the long side of the box, and a rigid and load-resistant beam structure is formed on all sides of the packaging box.
