• a second and a third blanks intended respectively to form the bottom and cover of the box each comprising a central flap to form the lower or upper face, each central flap being provided with two opposite free edges and two opposite lateral flaps arranged to cover at least partially the external surface of two opposite flaps suitable for forming the lateral faces, in line with the respective free edges of said flaps, to be glued to them.
• the flaps of two opposite flaps of the series of flaps suitable for forming the lateral faces have lateral edges of shape complementary or adaptable to the lateral edges of the flaps of the adjacent flaps of said series of flaps;
• the upper free edges of two of the side flaps intended to form the side are sides of the case are provided with at least one stacking tab, and the flaps of the folding lines of the central flap of the lid wall comprises one or several corresponding notches; - At least two blanks among the first, second and third blanks are corrugated cardboard of different quality and / or thickness.
• the first blank is made of thin double-sided cardboard, for medium compressive strength
• the bottom is made of double-double or double-sided thick cardboard to support heavy products
• the lid is made of corrugated cardboard. Double face of medium thickness, to allow a good grip for suction cups.
• the invention also provides a box obtained with a set of blanks as described above. It also offers a box with polygonal section comprising lateral faces, an upper face forming a cover and a lower face forming the bottom of the box, characterized in that two opposite lateral faces are devoid of flap on the side of the cover and provided with flaps of the side of the bottom, and two other opposite faces are devoid of flap on the side of the bottom and provided with flaps on the side of the cover, said flaps being respectively glued to the upper face and the lower face of the body, and in that the bottom and the cover are respectively formed of a single central flap provided with two opposite free edges and two opposite side flaps, said flaps being respectively glued to the outer surface of corresponding side faces, in line with the respective free edges of said faces.
