The front wall has an inner layer having a top edge abutting the top wall and an outer layer. The outer layer has a horizontal tear strip thereacross which is integral with the tear strips of the end walls, forming one continuous tear strip. A glue flap is integrally attached to the top edge of the inner layer of the front wall along substantially its full length. The glue flap has a distal attachment portion and a proximal locking portion. The two portions are joined along a full length line of weakness. The distal attachment portion is secured to the inner surface of the outer layer of the front wall above the tear strip.
