The present invention relates to a method of assembling a group of irregular tetrahedral packages (1a, 1b) having a first orientation and a mirrored second orientation, said packages (1a, 1b) each having two panels (5, 6) that are isosceles right triangles, and two elongated panels (7, 8) that are right triangles. The method comprises the steps of providing an L-shaped blank (10) having a rectangular central wall (15), a rectangular right wall (13), and a rectangular left wall (14), the right wall (13) and the left wall (14) being attached on neighbouring edges of the central wall (15) via weakening lines (11, 12), arranging one package (la) with a first orientation and one package (lb) with a second orientation on each of the right wall (13), left wall (14) and central wall (15), wherein all packages (la, lb) are placed such that a panel (5, 6) with isosceles right triangle shape faces the cardboard blank (10), and where the hypotenuse of said panel is directed towards a central corner (16), between the right wall (13) and the left wall (14), and such that the top downward angled edges of all packages also are directed towards said central corner (16), such that the cardboard blank can be folded into a cube by angling the right wall (13) from an unfolded position, and by angling the left wall (14) from an unfolded position, until the packages (la, lb) rest on top of the packages (la, lb) on the central wall (15). |
