Abstract:
1. A rigid wrapper for packets of cigarettes, the wrapper ( 1 ; 80 ; 86 ) comprising a hinged lid ( 10 ) and appearing substantially as a rectangular parallelepiped with a predominating longitudinal axis (L), presenting a front face ( 24 ) and a rear face ( 25 ), a first end face ( 19 ) and a second end face ( 15 ), top and bottom respectively, and two mutually parallel flank faces ( 26 ), the wrapper being fashioned from a flat blank ( 42 ; 81 ; 99 ) and presenting a first longitudinal axis (L′) parallel to the predominating axis (L) and a second transverse axis (T) perpendicular to the first axis, comprising a main portion ( 43 ) ultimately providing the container ( 8 ) and the lid ( 10 ) of the wrapper ( 1 ), and a longitudinal appendage ( 44 ) ultimately providing the frame ( 27 ), wherein the main portion ( 43 ) of the blank ( 42 ; 81 ; 99 ) presents a first and a second transverse crease line ( 45 , 46 ) extending parallel to the transverse axis (T) and a plurality of first longitudinal crease lines ( 47 . . . 54 ) extending parallel to the longitudinal axis (L′), combining with the first and second transverse crease lines ( 45 , 46 ) to delimit a front central panel ( 24 ′), two lateral portions ( 26 ′) lying one on either side of the central panel ( 24 ′), and an end panel ( 25 ′) and a longitudinal end flap ( 55 ) lying externally of the respective lateral portions ( 26 ′), the central panel ( 24 ′) associated at the two opposite longitudinal extremities with two first end folds ( 19 ′, 15 ′), and the end panel ( 25 ′) associated at the two opposite longitudinal extremities respectively with a second end fold ( 56 a ) to which it is joined along the first transverse crease line ( 45 ), and a third end fold ( 56 b ), opposite the second end fold ( 56 a ), to which it is joined along the second transverse crease line ( 46 ); each lateral portion ( 26 ′) associated at the longitudinal extremity delimited by the first transverse crease line ( 45 ) with a relative transverse end flap ( 57 ); the appendage ( 44 ) presenting a substantially U shaped appearance and comprising two lateral arms ( 35 ′), also a transverse panel ( 30 ′) associated on either side with the two arms ( 35 ′) by way of two respective first longitudinal crease lines ( 66 , 67 ; 68 , 69 ); the appendage ( 44 ) being hinged by the two arms ( 35 ′) to corresponding longitudinal ends of the respective lateral portions ( 26 ′) coinciding with the second transverse crease line ( 46 ), and surrounding one first end fold ( 15 ′) of the central panel ( 24 ′); the main portion ( 43 ) of the blank exhibiting a transverse perforation line ( 58 ) extending across the front central panel ( 24 ′) and the two lateral portions ( 26 ′), along which the lid ( 10 ) is separated from the container ( 8 ), joined at one end to a transverse crease line ( 11 ′) extending across the end panel ( 25 ′) and at the other end to a perforation line ( 60 ) extending across the longitudinal end flap ( 55 ), the crease and perforation lines ( 11 ′, 60 ) coinciding with the hinge line ( 11 ) along which the lid ( 10 ) is joined to the container ( 8 ); the one first end fold ( 19 ′) being designed to overlap with the corresponding second end fold ( 56 a ) and combine with the end flaps ( 57 ), bent along the first transverse crease line ( 45 ), to constitute a first top end face ( 19 ) of the lid ( 10 ); the other first end fold ( 15 ′) being designed to overlap with the corresponding third end fold ( 56 b ), bent along the second transverse crease line ( 46 ), to constitute a second bottom end face ( 15 ) of the container ( 8 ); the longitudinal end flap ( 55 ) being designed to overlap with a marginal portion of the inside surface of the end panel ( 25 ′); the appendage ( 44 ) being bent double along the second transverse crease line ( 46 ), flattened against the main portion ( 43 ) and fixed to the inside surfaces of the central panel ( 24 ′) and of the lateral portions ( 26 ′) directed toward the inside of the wrapper ( 1 ; 80 ; 86 ); at least each first end fold ( 19 ′, 15 ′) presenting a first profile ( 77 ) coinciding with at least one end portion of a respective longer side edge ( 70 , 72 ) disposed adjacent to the respective first or second transverse crease line ( 45 , 46 ), and connecting the respective longer side edge ( 70 , 72 ) with a shorter side edge ( 71 , 73 ) of the respective first end fold ( 19 ′, 15 ′) adjoining the selfsame longer side edge ( 70 , 72 ); the third end fold ( 56 b ) presenting a third profile ( 78 ) coinciding with at least one end portion of a respective longer side edge ( 74 ) disposed adjacent to the second transverse crease line ( 46 ), and connecting the longer side edge ( 74 ) with a shorter side edge ( 75 ) of the third end fold ( 56 b ) adjoining the selfsame longer side edge ( 74 ); the first and third connecting profiles ( 77 , 78 ) coinciding, when the wrapper ( 1 ; 80 ; 86 ) is erected, with the longitudinal connecting elements ( 38 , 39 , 40 , 41 ) both of the lid ( 10 ) and of the container ( 8 ).
