Pack of rigid type for tobacco products

Abstract

A rigid pack ( 1 ) of essentially parallelepiped appearance, designed to contain cigarettes, is composed of an inner packet ( 5 ) with a hinged lid ( 8 ), and an open-fronted box or case ( 6 ) affording a recess ( 20 ) in which the packet ( 5 ) is nested with the back ( 11 ), top ( 14 ), bottom ( 13 ) and flanks ( 12 ) offered in contact respectively to the back ( 17 ), transverse walls ( 19 ) and longitudinal walls ( 18 ) of the case ( 6 ), and with the inner packet ( 5 ) anchored along the front corner edge between the front wall ( 10 ) and the bottom ( 13 ), to the free edge presented by a corresponding transverse wall ( 19 ) of the outer case ( 6 ); the inner packet ( 5 ) is able to pivot on this corner edge, which functions as a hinge ( 21 ), between the nested position and a position partially extracted from the case ( 6 ). Also forming part of the pack is a linkage element ( 26 ) operating between the case ( 6 ) and the packet ( 5 ) in such a way as will cause the lid ( 8 ) to flip open automatically when the pack is opened.

1 . A rigid pack for tobacco products, substantially parallelepiped in appearance, characterized
 in that it comprises an inner box element or packet ( 5 ) presenting four side walls extending parallel to a longitudinal axis (A), including a front wall ( 10 ), a rear wall or back ( 11 ), two flanks ( 12 ) and at least one end wall ( 13 ) disposed transversely to the longitudinal axis (A), also an outer box element or case ( 6 ) presenting a rectangular back wall ( 17 ) and, associated rigidly with the selfsame along the four sides, two longitudinal walls ( 18 ) and two transverse walls ( 19 ), creating a parallelepiped recess ( 20 ) in which to house the inner box element ( 5 ) disposed with the back ( 11 ) breasted in contact with the rear wall ( 17 ), the end wall ( 13 ) in contact with a corresponding transverse wall ( 19 ) and the two flanks ( 12 ) in contact with the longitudinal walls ( 18 );   in that the inner box element ( 5 ) is hinged along one corner edge, coinciding with the join between the front wall ( 10 ) and the end wall ( 13 ), to a corresponding transverse wall ( 19 ) of the outer box element ( 6 ) and rotatable thus in relation to the outer box element ( 6 ) about a corner edge that functions as a hinge ( 21 ), between a nested first position and a partially extracted second position.

       6 . A pack as in  claim 1 , wherein the main or back wall ( 17 ) of the outer box element ( 6 ) presents an opening ( 30 ) through which the rear wall or back ( 11 ) of the inner box element ( 5 ) is accessible. 
   
   
       7 . A pack as in  claim 1 , wherein the front wall ( 10 ) of the inner box element ( 5 ) comprises tab means ( 33 ) such as can be pulled to extract the selfsame inner box element ( 5 ) from the outer box element ( 6 ). 
   
   
       8 . A rigid pack for tobacco products as in  claim 1 , wherein the outer box element ( 6 ) and the inner box element ( 5 ) are fashioned respectively from a first flat blank ( 6 ′) and from a second flat blank ( 5 ′), with at least one of the two blanks ( 6 ′,  5 ′) incorporating a flap ( 37 ) that serves to connect the first and the second box elements ( 5 ,  6 ) one to another. 
   
   
       9 . A pack as in  claim 8 , wherein the flap ( 37 ) constitutes an end flap of the first blank ( 6 ′) and is joined to the selfsame blank along a crease line ( 21 ′) serving to establish the hinge ( 21 ). 
   
   
       10 . A pack as in  claim 9 , wherein the first blank ( 6 ′) is of substantially rectangular outline, with the predominating dimension referable to a longitudinal axis (A″), and comprises:
 a plurality of longitudinal crease lines and transverse crease lines, delimiting a central panel ( 17 ′) that provides the back ( 17 ) of the outer box element, two longitudinal panels ( 18 ′) providing the longitudinal walls ( 18 ), and two transverse panels ( 19 ′) providing the transverse walls ( 19 );   two end panels ( 25 ′) joined one to each of the longitudinal panels ( 18 ′) and folded to create a stop ( 25 ) that serves, in use, to limit the angle through which the inner box element ( 5 ) is allowed to rotate about the second hinge ( 21 );   flaps ( 38 ) associated with the ends of each longitudinal panel ( 18 ′), providing a connection between the longitudinal walls ( 18 ) and the transverse walls ( 19 ).
