Flip-top packet for cigarettes

Abstract

A hinge-lid box for cigarettes, namely for a cigarette block ( 13 ), is designed, in the region of a lid ( 11 ) and in the region of a base wall ( 17 ) in each case, such that cavities namely chambers ( 50 ), are formed on the inside. For this purpose, an end wall ( 21 ) and a base wall ( 17 ) are partially or predominantly rounded in order to space the end wall ( 21 ) or base wall ( 17 ) apart from the cuboidal cigarette block ( 13 ).

       22 . The hinge-lid box as claimed in  claim 18 , characterized in that the end wall ( 21 ) is of at least double-layered design in the central section ( 26 ), specifically by virtue of a crosspiece ( 35 ) being arranged on the outside of end wall ( 21 ) and/or base wall ( 17 ), with end regions of the end tabs ( 27 ,  28 ) being fastened on an inner side of the crosspiece ( 35 ).  
   
   
       23 . The hinge-lid box as claimed in  claim 18 , characterized in that the end wall ( 21 ) has rounded side sections ( 25 ) and a planar, transverse central section ( 26 ), with the side sections ( 25 ) being of at least partially elliptical design with a pronounced curvature in the region of the side walls ( 16 ,  20 ).  
   
   
       24 . The hinge-lid box as claimed in  claim 22 , characterized in that the lid front wall ( 18 ) and lid rear wall ( 19 ) conform to the contour of the end wall ( 21 ) and base wall ( 17 ) and are connected to one another in the central region by the crosspiece ( 35 ).  
   
   
       25 . The hinge-lid box as claimed in  claim 22 , characterized in that the end wall ( 21 ) in sub-regions outside the crosspiece ( 35 ) is supported on a free edge of the lid front wall ( 18 ) and lid rear wall ( 19 ) by means of a broadening ( 42 ) provided on the end tabs ( 27 ,  28 ).  
   
   
       26 . The hinge-lid box as claimed in  claim 18 , characterized in that, in addition to the chamber ( 50 ) formed above the cigarette block ( 13 ) or, as an alternative to this chamber ( 50 ), a free chamber ( 51 ) is formed below the pack contents ( 3 ) on the base side, with a base wall ( 17 ) as well as box front wall ( 14 ) and box rear wall ( 15 ) being configured analogously to end wall ( 21 ) and/or lid front wall ( 18 ) and/or lid rear wall ( 19 ) in order to delimit the base-side chamber ( 51 ).  
   
   
       27 . The hinge-lid box as claimed in  claim 21 , characterized in that the end wall ( 21 ) and/or base wall ( 17 ) comprise/comprises the two oblique side sections ( 25 ) and the horizontal or transverse central section ( 26 ), the oblique side sections ( 25 ) adjoining the side walls ( 20 ,  16 ), on the one hand, and the central section ( 26 ), on the other hand, at an obtuse angle in each case.  
   
   
       28 . The hinge-lid box as claimed in  claim 27 , characterized in that the chamber ( 50 ), which is formed at least above the cigarette block ( 13 ), is of trapezoidal design in cross section.  
   
   
       29 . The hinge-lid box as claimed in  claim 28 , characterized in that the end wall ( 21 ) as a whole, namely over its entire width, is directed obliquely in a roof-like shape and has a planar design.  
   
   
       30 . The hinge-lid box as claimed in  claim 29 , characterized in that the end tabs ( 27 ,  28 ) are extended beyond the cigarette block ( 13 ) in the plane of the lid side wall ( 20 ) on at least one side and can be folded over into the oblique plane of the end wall ( 21 ) at a distance above the cigarette block to form a peripheral edge ( 54 ,  55 ) and butt against said end wall on the inside.  
   
   
       31 . The hinge-lid box as claimed in  claim 21 , characterized in that the end wall ( 21 ) and/or the base wall ( 17 ) are spaced apart from the pack contents by a smaller distance in a preferably central sub-region than in lateral regions such that the chamber ( 50 ) has lateral widenings or comprises two lateral sub-chambers.  
   
   
       32 . The hinge-lid box as claimed in  claim 31 , characterized in that the end tabs ( 27 ,  28 ) are extended beyond the cigarette block ( 13 ) in the plane of the lid side wall ( 20 ), are folded at an acute angle, and directed obliquely downward, in the region of the peripheral edge ( 54 ,  55 ), and have a horizontally folded end leg ( 52 ) on the inside of the crosspiece ( 35 ).  
   
   
       33 . The hinge-lid box as claimed in  claim 18 , characterized in that end tabs ( 27 ,  28 ) of the lid side walls ( 20 ) and/or of the box side walls ( 16 ) butt against free peripheral edges of the lid front wall ( 18 ) and lid rear wall ( 19 ) and/or of the box front wall ( 14 ) and box rear wall ( 15 ), specifically by way of a broadening of the end wall ( 21 ) or base wall ( 17 ) and/or of the end tabs ( 27 ,  28 ) which is formed in the abutment region.
