Abstract: A shipping/display container that may be opened without having to use a knife or other sharp instrument, and a blank for forming such a container. The container blank includes a plurality of side panels foldably connected together in a longitudinal series, and a connecting flap foldably connected to a first end of the side panels. The side panels form a line of weakness extending substantially completely across each of the side panels, and the connecting flap forms a notch extending from the first end of the side panels. To form the container, the connecting flap is connected to the second end of the side panels, forming the side panels into a continuous side wall for the container; and as this is done, the notch in the connecting flap is positioned over the end portion of the line of weakness.
