The box comprises a base (1) that is in the shape of a quadrilateral, and whose sides are continued by two main flaps (2,3) and two auxiliary flaps (4,5), respectively associated with two opposed sides (6,7) & (8,9) of the base by a fold line. The flaps have no fold and their width b,b1 increases starting from the side a,a1,6,7,8,9 of the base, their edge (21,31,41,51) having a convex shape, in order to decrease again towards the end (22,32,42,52). The main flaps are continued by a locking and gripping tab (10,11) connected to the flaps by a fold line (12,13). The auxiliary flaps have a longitudinal slot (14,15) in their end (42,52) to receive the tabs of the main flaps when the latter are brought together by their tabs. The auxiliary flaps curve against the edges (41,51) of the main flaps, bearing against the latter and being hooked, by their slot, onto the tabs. |
