Title: BLANK FOR MAKING ROUND BOXES
Abstract:
A blank for making round boxes comprises at least one panel (2, 2') which can be folded along a curved trajectory so as to define a side wall (P) of a round box and has the form of a parallelogram with a first edge and second edge (3, 4; 3', 4') situated opposite each other and a third edge and fourth edge (5, 6; 5', 6') also situated opposite to each other and transverse to the first edge and second edge (3, 4; 3', 4'). The first edge and second edge (3, 4; 3', 4') have respective outer profiles which complement each other and are formed so that, following folding along said curved trajectory, the first edge and second edge (3, 4; 3', 4') can be brought into end-to-end contact with each other along a helical joining line (G).
