  • this design of the diagonal crease line 235 and 435 is equally suitable for cartons having a crease line separating the front wall section 606 and the front roof section 616. Consequently, in alternative embodiments, the front wall section and the front roof section may be separated by a transverse crease line, e.g. as is shown in Fig. 9 .

  • FIG. 11 Yet another embodiment of a carton blank 50 according to the invention is shown in Fig. 11 .
  • the carton blank 50 differs from the carton blank 40 of Fig. 10 in that the first panel P1 has no transverse crease line separating the wall section sub-panel 120 and the top-closure sub-panel 130. Consequently, in the carton formed from the blank 50, the back wall will be continuous with the back roof section via a curved transition area in the same manner as is the case for the front wall 606 and the front roof section 616 of the carton 600 shown in Figs. 6-8 .

  • Figs. 13a and 13b show such an embodiment of a carton blank where the diagonal crease lines 235, 435 and the transverse crease lines 250, 450 terminate prior to reaching the respective top corner position TC2, TC3, but sufficiently close, i.e. within 0-5 mm, to define a folding line extending to the top corner position.
  • TC3 may still provide precise folding of the carton blank, although extending the crease lines 235, 435, 250 and 450 all the way to the top corner positions TC2, TC3 may be preferable.
  • the subject of the present invention i.e. the design of the diagonal crease lines of the top-closure sub-panels of panels two and four
