Box and blank made from cardboard sheet with convex centring devices

The present invention relates to a box, a blank, a set of blanks made from corrugated cardboard sheet and a method for forming a box having a polygonal section. The box has at least one centring tab () straddling at least one folding line () on its upper wall (), cut out on its lateral sides (), connected on one side to the upper wall () by a first joining line () and on the other side to the adjacent side wall () by a second joining line (), a parallel and offset intermediate folding line () being provided such that the tab () forms a projecting portion () on account of the folding. The bottom comprises at least one perforated surface portion () which has a shape complementary to that of the tab such that the lateral edges of the recess are designed to cooperate in contact with the lateral edges of said tab, and is designed to fit into the projecting portion of a box from below.
