  • the fold lines 4 of the side wall of the box are perfectly superimposed on the fold lines 12 of the reinforcement.
  • FIG. 2 shows the blank 1, and the internal reinforcement 10, from which the box 1 shown in FIG. 1 can be produced by folding.
  • the relative dimensions, and in particular the distances between fold lines are calculated beforehand, for example by computer (CAD / CAM), so as to allow the exact superimpositions of the lines during assembly.
  • FIG 3 there is shown a blank for the production of a box of the type shown in Figure 1, but having a rectangular section with cut corners, that is to say whose side wall 2 has eight panels 3
  • the internal reinforcement belt 10 likewise has eight flaps 11.
  • the embodiment of the box 1 shown in Figure 4 differs from that of Figure 1 in that, in this case, the internal reinforcement belt 10 is associated with a bottom panel 14, in one piece , secured to box 1.
  • the latter then has, internally, a smooth bottom, avoiding possibly marking the products that it is intended to contain.
  • bottom flaps 6 can then constitute only part of the bottom of the box 1, as can be clearly seen in FIG. 4 in particular.
  • the external face of the panel 14, of rectangular shape, is joined by gluing, to the flaps 6.
