  • the width of these latter flaps is equal to half of l1 .
  • the manufacture of the blanks F9 is economical in sheet material, since two blanks F9 can be nested one inside the other, with longitudinal offset.
  • FIG. 41 there is shown a blank F10 in which the series of flaps 1 to 8 is such that the height h thereof is less than the width L of flaps 3 and 7, unlike what has been shown for the blanks F1 to F9, previously described.
  • the flaps 18.1 and 18.5 are substantially similar to those of the blank F2 of Figure 17, while the flaps 18.3 and 18.7 are substantially similar to those of the blank F1 of Figure 1.

  • the cover of the box C10 is formed by the folding and fixing the flaps 19.3 and 19.7 on the flaps 19.1 and 19.5, previously folded down, so that said flaps 19.3 and 19.7, projecting from the flaps 19.1 and 19.5, form cavities 96 at the ends of said checkout.
  • the shape of said cavities 96 corresponds to that of flaps 18.1 and 18.5.
  • the projections formed by the flaps 18.1 and 18.5 from the bottom of the upper body are housed in the cavities 96 of the lower case cover, of so that the cooperation of projections 18.1 and 18.5 and cavities 96 ensures the vertical stability of said boxes.
  • This stability is further reinforced by the fact that the flaps 2,4,6,8 include the projections 71 and the notches 70 of the blank F3 of FIG. 20, so that the box C10 has nipples 74 and similar recesses 73 to those of the C3 box, favoring the stacking of said C10 boxes.
  • the flaps 1 and 5 of the blanks F1 to F10 described above have been removed.
  • component 8 is linked to component 2 and carries the tab 16.
  • the box C11 has a hexagonal section and no longer octagonal.

  • Sections 2,3,4 and 7 include flaps 18.2, 18.3, 18.4, 18.7, 19.2, 19.3, 19.4 and 19.7 likely to form the bottom and the cover of the box C12.
  • the blank F13 of FIG. 50 comprises a series of eight identical flaps 1 to 8, to which are respectively associated with identical trapezoidal flaps 18.1 to 18.8 and 19.1 to 19.8.
  • Box C13 obtained from blank F13 therefore has an octagonal section corresponding to a square section with the four corners cut.

  • the blank F14 in FIG. 53 has a series of five flaps 3 to 7, the tongue 16 being linked to the first flap 3.
  • Box C14 therefore has a triangular section with two cut corners.
  • Part 5 carries flaps 18.5 and 19.5 of substantially corresponding triangular shape comprising their base inclined sides 22, to adapt to the faces side corresponding to flaps 4 and 6.
