A container having conventional top and bottom closure flaps, and side and end walls is provided with handhole cutouts in the end walls thereof and an integral means for reinforcing the handholes and for shielding the contents of the container from the ingress of light or contamination through the handhole cutouts. The integral means comprises a pair of panels which are cut from the conventional top minor closure flaps of the container so as not to eliminate the top minor closure flaps from their normal function as load supporting members for the top major closure flaps of the container.
