Hinge-lid packet for cigarettes

Abstract

A hinge-lid pack for cigarettes or other items usually consists of a box part and lid. In the closed position, the pack exhibits upright pack edges, namely longitudinal edges ( 29, 30 ) and transverse edges ( 31, 32, 33, 34 ). The longitudinal edges ( 29, 30 ) or transverse edges ( 31 . . . 34 ) are configured as a projection ( 35 ) or recess ( 40 ) having a round cross-section.

1 . A hinge-lid box, made of (thin) cardboard or similar packaging material, in particular for cigarettes, comprising a box part ( 10 ), lid ( 11 ) and collar ( 12 ) and having (upright) longitudinal edges ( 29 ,  30 ) and transverse edges ( 31 ,  32 ) running crosswise thereto, characterized in that the longitudinal edges ( 29 ,  30 ) and/or transverse edges ( 31 ,  32 ,  33 ,  34 ) are configured by the deformation or embossing of the packaging material as an outwardly directed projection ( 35 ) having a round cross-section or an inwardly directed recess ( 40 ) having a round cross-section.  
   
   
       2 . The hinge-lid pack according to  claim 1 , characterized in that the pack edges configured as a projection ( 35 ) have a cross-section in the shape of a pitch circle, approximately in the shape of a three-quarter circle.  
   
   
       3 . The hinge-lid pack according to  claim 1 , characterized in that the pack edges configured as a recess ( 40 ) have a cross-section in the shape of a pitch circle, correspond approximately to a quarter-circle.  
   
   
       4 . The hinge-lid pack according to  claim 1 , characterized in that all four upright longitudinal edges ( 29 ,  30 ) are uniformly configured as a projection ( 35 ) or as a recess ( 40 ).  
   
   
       5 . The hinge-lid pack according to  claim 1 , characterized in that upper and lower transverse edges ( 31  . . .  34 ) for delimiting an end wall ( 18 ), on one hand, and a base wall ( 15 ) on the other hand, are configured as projections ( 35 ) or as recesses ( 40 ).  
   
   
       6 . The hinge-lid pack according to  claim 1 , characterized in that the collar ( 12 ) has collar edges ( 43 ,  44 ) which correspond in shape to the longitudinal edges ( 29 ,  30 ).  
   
   
       7 . The hinge-lid pack according to  claim 1 , characterized in that for the configuration of the transverse edges ( 31 ,  32 ,  33 ,  34 ) as a projection ( 35 ) or recess ( 40 ), corner tabs, namely base corner tabs ( 27 ) and/or end corner tabs ( 28 ) are configured with a smaller width such that the corner tabs ( 27 ,  28 ) can be positioned exclusively between the transverse edges ( 31  . . .  34 ) configured as a projection ( 35 ) or recess ( 40 ).  
   
   
       8 . The hinge-lid pack according to  claim 1 , characterized in that the projection ( 35 ) and/or recess ( 40 ) have a radius of 1.5 mm to 4 mm.  
   
   
       9 . The hinge-lid pack according to  claim 1 , characterized by a blank which in its non-folded state is provided with embossments ( 46 ) or reinforcing seams ( 47 ) formed by deformation and having an (approximately) semicircular-shaped cross-section in the region of the longitudinal edges ( 29 ,  30 ) and/or transverse edges ( 31 ,  32 ,  33 ,  34 ), with the projections ( 35 ) or recesses ( 40 ) being formed by the folding of folding tabs or walls causing deformation of the embossment ( 46 ) or reinforcing seam ( 47 ) such that, given a pre-determined dimension of the embossment ( 46 ) or reinforcing seam ( 47 ), a projection ( 35 ) has a smaller radius and a recess ( 40 ) has a greater radius than the embossment ( 46 ) or reinforcing seam ( 47 ).
