ABSTRACT:
A blank 10 for the folding of a filp-top cigarette box includes laterally successive surface areas defining a first side wall 16, a front wall 17, a second side wall 18 and a back wall 19 of a main box portion 11. The front and side wall portions 21, 22, 23 of the lid 12 initially lie at an angle above the main box walls, and are connected at one end at a pivot point 42 and at the other end by a bridging portion 41 of a glue strip 20. The space provided by the angling is occupied by a trapezoidal lid reinforcing flap 35 flanked by intermediate punch-out elements 37, 38. During an initial processing step the lid portions are rotated in the plane of the blank about the pivot point and the bridging portion is double folded, to thus bring the lid and main box portions into abutment. Adjacent lines of longitudinally reversed and displaced blanks are laid out on a strip of packaging material with the trapezoidal projections and recesses of their edges interleaved, to thus minimize material waste.
