Claim:
A method of producing a rigid, hinged-lid packet, the method comprising: folding a first blank ( 23 ) about a group ( 46 ) of cigarettes to form an container ( 2 ) with a hinged lid ( 5 ); folding a second blank ( 31 ) about the container ( 2 ) to form an outer tubular slide ( 14 ) surrounding the container ( 2 ) to slide axially with respect to the container ( 2 ); the outer tubular slide ( 14 ) having a transmission member ( 19 ), in turn having a first end ( 21 ) integral with the lid ( 5 ), a second end ( 20 ) opposite the first end ( 21 ) and integral with the slide ( 14 ), and a deformable intermediate portion ( 22 ) having a U-shaped fold between the container ( 2 ) and the slide ( 14 ); folding the transmission member ( 19 ) into a U and 180° onto a panel ( 16 ′) of the second blank ( 31 ) before folding the second blank ( 31 ) about the container ( 2 ); forming on the transmission member ( 19 ) a central fastening portion ( 40 ) separated from the rest of the transmission member ( 19 ) by an endless tear line ( 41 ) which is torn when unsealing the lid ( 5 ); and gluing the central fastening portion ( 40 ) of the transmission member ( 19 ) to the panel ( 16 ′) of the second blank ( 31 ) before folding the second blank ( 31 ) about the container ( 2 ).
