<p>The bucket is made from a corrugated cardboard blank (12), s coated on one face with a hydrophobic material. The blank external outline is polygon shaped and has in its center a polygonal base wall (20) delimited by a series of folding lines (14-19) parallel to the sides (21-26). The blank has a second series of folding lines (27-32) which connect the tops of the base wall to the tops of the outline. A third series of folding lines (33-44) issue from the tops of the base wall and are slightly inclined to the external outline sides, thereby defining a side wall (45-50) and triangular flaps (51-62).</p> |
