ABSTRACT:
The cardboard blanks for conversion into hinged-lid packets for arrays of cigarettes are dimensioned and configurated in such a way that an elongated reinforcing strip at the inner side of the front panel of the lid is longer than the front panel. Those terminal sections of the reinforcing strip which extend beyond the ends of the front panel in a blank are bent prior to or during the folding of the reinforcing strip against the inner side of the front panel so that they do not adversely affect the configuration of the lateral panels of the lid and the appearance of a finished packet because the lateral panels are not caused to bulge outwardly.
