A first end flap is coupled to the first side wall panel and has an upper edge defining a notch. A second end flap is coupled to the second side wall panel on the opposite side of the first end wall panel from the first end flap and has an upper edge defining a notch. A rollover flap is coupled to the first end wall panel by a trapezoidal hinge portion. The first and second end flaps are folded into an overlapping arrangement inward of the first end wall panel such that the notches of the first and second end flaps are aligned. The rollover flap is folded over the first and second end flaps and downwardly inside the container, and the hinge portion is received in the notches to form the first end wall.",
