ABSTRACT:
A blank has four top wall areas which serve as flaps for forming the top of a parallelepiped box. Fold lines connect the top wall areas to each other to reduce the risk of leakage from the box. One of the top wall areas has two oblique fold lines therein or at its edges, and two other top wall areas are formed to permit the formation of a spout for dispensing the contents of the box. These spout-forming top wall areas are provided with oblique folding lines which extend to a corner of the box and are arranged to register with each other in the completed box. Markings and/or a line of weakness identify a severance line which, after being severed, permits movement of portions of the spout forming top wall areas to a vertical position to provide a dispensing spout.
