1. A box made of corrugated cardboard sheet material and having a polygonal cross section, including side walls, an upper wall forming a top of the box and a lower wall forming a bottom of the box, the upper wall and the side walls being connected through folding lines, wherein the top of the box co
1. A box made of corrugated cardboard sheet material and having a polygonal cross section, including side walls, an upper wall forming a top of the box and a lower wall forming a bottom of the box, the upper wall and the side walls being connected through folding lines, wherein the top of the box comprises at least one cut-out convex portion which protrudes slightly in relation to the upper wall while remaining substantially in a same plane as the upper wall, and the bottom of the box comprises at least one corresponding portion having a perforated surface and having a complementary shape to the convex portion, situated opposite the convex portion and arranged so as to be fitted into a convex portion of a box below, wherein the convex portion is formed by a tongue that is partially cut out in the upper wall, connected on one side that is deformed by folding in a junction zone between the upper wall and an adjacent one of the side walls, and is cut out on its other sides in relation to the upper wall, andwherein the upper wall is formed at least in part by a flap that is attached in the junction zone to the adjacent one of the side walls, via one of the folding lines that includes a first part of the one of the folding lines that is not in alignment with a second part of the one of the folding lines, the first part of the one of the folding lines being situated substantially opposite the convex portion in order to form the side that is deformed by folding in the junction zone. 2. The box as claimed in claim 1, wherein the upper wall is formed at least in part by two flaps, the convex portion being pre-cut into a corresponding flap by a line in the form of a flattened Ω of which a summit faces towards an interior of the box. 3. The box as claimed in claim 1, wherein the lower wall and the side walls are formed by a tray and the upper wall is formed by a cover. 4. The box as claimed in claim 1, and having a center wherein the box comprises at least two convex portions, which are symmetrical in relation to the center of the box. 5. The box as recited in claim 4, wherein the at least two convex portions have a generally rounded shape as a portion of a circle. 6. The box as claimed in claim 1, and having a transversal axis wherein the box comprises two sets of two convex portions, which are symmetrical in relation to a transversal axis of the box. 7. A blank or a set of blanks made of corrugated cardboard sheet material intended to form a box having a polygonal cross section and including side walls, an upper wall and a lower wall forming a bottom of the box, wherein the upper wall is formable by at least one flap that is attached to a top of an adjacent one of the side walls in a junction zone via a folding line that includes a first part of the folding line that is not in alignment with a second part of the folding line, wherein at least one portion is connected on a deformable side in the junction zone and is partially cut out in the flap on its other sides, the deformable side being substantially opposite and in proximity to the first part of the folding line, in order to form, upon folding on the deformable side, a convex portion that protrudes slightly in relation to a top surface of the box while remaining substantially in a same plane as the top surface, andwherein the bottom comprises at least one portion of a corresponding perforated surface having a complementary shape to the convex portion. 8. The blank or set of blanks as claimed in claim 7, wherein the first part of the folding line is parallel to and is offset from the second part of the folding line by a distance e, wherein e lies between 1 and 5 mm. 9. The blank or the set of blanks as claimed in claim 8, wherein the blank or the set of blanks comprises two sets of two partially cut-out portions that are symmetrical in relation to a transversal axis of the blank. 10. The blank or set of blanks as claimed in claim 7, wherein the blank or set of blanks comprises four flaps forming the lower wall of the bottom of the box, and the upper wall comprises at least two partially cut-out portions, which are symmetrical in relation to a center of the blank, in order to constitute the convex portion during formation of the box. 11. The blank or set of blanks are recited in claim 10, wherein the at least two partially cut-out portions have a generally rounded shape as a portion of a circle. 12. The blank or set of blanks as claimed in claim 7, wherein the set of blanks comprises a first blank for forming the bottom of the box and a second blank forming the upper wall, the said upper wall comprising at least two partially cut-out portions that are symmetrical in relation to a center of the second blank, in order to constitute the convex portion during formation of the box. 13. The blank or the set of blanks as claimed in claim 7, wherein the at least one portion is cut out in the upper wall by a line in the form of an Ω of which a summit faces towards a side opposite the first part of the folding line. 14. The blank or the set of blanks as claimed in claim 7, wherein the blank or the set of blanks comprises two flaps in order to form the upper wall at least in part.
