Abstract
A frangible line defines a line of severance by extending across a carton wall that has a seam. The frangible line is extensively weakened along a predetermined segment where it traverses the seam. Preferably, the predetermined segment is extensively weakened by substantially disjoining the panel regions on either side of the line. Disjoinder is preferably achieved by making the predetermined segment a cut line.
