Packaging blank for forming a package and package formed from a packaging blank

Abstract

A packaging blank for forming a package filled with a pourable product includes at least a first transversal crease line and a second transversal crease line extending transversally to a longitudinal axis of the packaging blank and dividing the packaging blank into a top region containing a top crease pattern and a bottom region containing a bottom crease pattern and an intermediate region contained between the first transversal crease line and the second transversal crease line. The first transversal crease line delimits the top crease pattern and the second transversal crease line delimits the bottom crease pattern. The packaging blank further comprises a plurality of linear crease lines parallel to the longitudinal axis and extending from the first transversal crease line and towards the second transversal crease line. Each linear crease line is parallel to the longitudinal axis and extends along only a portion of the intermediate region.

         5 . Packaging blank according to  claim 3 , wherein the first linear crease line and the second linear crease line are closer to respectively the first transversal boundary edge and the second transversal boundary edge than to a center point of the first transversal crease line. 
     
     
         6 . Packaging blank according to  claim 3 , wherein no further linear crease line extending from the first transversal crease line and towards the second transversal crease line is interposed between the first linear crease line and the second linear crease line 
     
     
         7 . Packaging blank according to  claim 3 , and further comprising one or more linear crease lines interposed between the first linear crease line and the second linear crease line. 
     
     
         8 . Packaging blank according to  claim 1 , wherein at least the first transversal crease line and the second transversal crease line define respective panels, which give origin and/or correspond to at least the top portion, the intermediate portion and the bottom portion of the respective package;
 wherein each linear crease line is arranged in correspondence of a respective section defined by one or more respective panels, which in turn corresponds to a respective corner of the respective top portion.   
     
     
         9 . Packaging blank according to  claim 1 , wherein the top crease pattern defines panels that form the top portion of the package and the bottom crease pattern defines panels that form the bottom portion of the package;
 wherein each linear crease line is arranged in correspondence of a section defined by one or more panels, which in turn corresponds to a corner of the top portion.   
     
     
         10 . Packaging blank according to  claim 1 , wherein each linear crease line has an extension ranging between 5 mm to 25 mm. 
     
     
         11 . Packaging blank according to  claim 1 , wherein each one of the linear crease lines has the same extension as the other linear crease lines. 
     
     
         12 . Packaging blank according to  claim 1 , and further comprising a plurality of auxiliary linear crease lines extending from the second transversal crease line and towards the first transversal crease line;
 wherein each auxiliary linear crease line only extends along a portion of the intermediate region.   
     
     
         13 . Packaging blank according to  claim 12 , wherein each auxiliary linear crease line is parallel to the longitudinal axis.
