Pack for smoking articles

Abstract

A pack for smoking articles substantially in the form of a generally rectangular parallelepiped includes a pair of opposed major side walls; a pair of opposed minor side walls; four longitudinal edges between the major and minor side walls; and a pair of substantially rectangular opposed end faces defined by transverse edges of the major and minor side walls. At least one of the opposed substantially rectangular end faces is an open end face defined by free transverse edges of the major and minor side walls, at least one of the four longitudinal edges has a non-right-angled portion and the transverse perimeter of the pack is substantially constant. The pack is preferably formed from a folded blank and the non-right-angled portion is preferably defined by at least three lines of weakness in the blank.

1 . A pack for smoking articles substantially in the form of a generally rectangular parallelepiped, the pack comprising:
 a pair of opposed major side walls;   a pair of opposed minor side walls;   four longitudinal edges between the major and minor side walls; and   a pair of opposed substantially rectangular end faces defined by transverse edges of the major and minor side walls,   wherein at least one of the opposed substantially rectangular end faces is an open end face defined by free transverse edges of the major and minor side walls, at least one of the four longitudinal edges has a non-right-angled portion and the transverse perimeter of the pack is substantially constant.   
   
   
       2 . A pack according to  claim 1 , wherein at least one of the four longitudinal edges has a pair of opposed substantially right-angled portions adjacent the opposed substantially rectangular end faces, and the non-right-angled portion is disposed between the pair of substantially right-angled portions. 
   
   
       3 . A pack according to  claim 1  wherein at least one of the four longitudinal edges has a non-right-angled, generally flat bevelled portion. 
   
   
       4 . A pack according to  claim 1 , wherein at least one of the four longitudinal edges has a non-right-angled, generally rounded portion of substantially curved transverse cross-section. 
   
   
       5 . A pack according to  claim 1  formed from a folded blank, wherein at least one of the four longitudinal edges has a non-right-angled portion formed by at least two longitudinal lines of weakness in the blank. 
   
   
       6 . A pack according to  claim 5  wherein the at least two longitudinal lines of weakness are generally parallel, with one being in a respective adjacent major side wall of the pack and another being in a respective adjacent minor side wall of the pack. 
   
   
       7 . A pack according to  claim 5  wherein at least one of the four longitudinal edges has a non-right-angled portion formed by at least three longitudinal lines of weakness in the blank. 
   
   
       8 . A pack according to  claim 1  wherein at least one of the four longitudinal edges has a rounded portion of substantially outwardly convex transverse cross-section. 
   
   
       9 . A pack according to  claim 1  wherein each of the four longitudinal edges has a non-right-angled portion.
