Abstract

A container blank particularly suitable for carrying liquids formed from a paperboard web fed in from a roll, the upper and lower edges of which are provided with short cut lines along the score lines forming the side panels. The method for obtaining such as blank consists of a set of rectilinear cut lines spaced apart from each other in correspondence of said upper and lower edges executed at the same time as said short cut lines or during a following stage, the lips defined by short cut lines and by score lines parallel to the edges being folded over and brought into contact with the corresponding panels simultaneously with the carrying out of short cut lines or later after the side seaming of the blank; in this way the container can selectively exhibit different types of top and bottom end closures.
