A corrugated paperboard container (10) has a bottom (11), opposite side walls (12, 13) and opposite end walls (14, 15). The end walls include an end panel (18) that is foldably connected to the bottom, and end flap panels (16, 17) that are foldably connected to the side walls. A roll-over flap (23)
A corrugated paperboard container (10) has a bottom (11), opposite side walls (12, 13) and opposite end walls (14, 15). The end walls include an end panel (18) that is foldably connected to the bottom, and end flap panels (16, 17) that are foldably connected to the side walls. A roll-over flap (23) is connected to the end wall by a web (24), and a notch (20) is in the top edge of the end flap panels. The end wall panel and end flap panels are folded into overlying relationship, and the roll-over flap is folded over an upper edge of the end wall panel, with the web lying in the notch. A projection or hook (41) extends into one side of the notch to engage an edge of the web to retain the web in the notch. A blank for making the container is also disclosed. A cover (50, 70) for the container, and a blank for making the same, include an end wall panel (54, 75) and end flap panels (57, 58), with a roll-over flap (23, 76) connected to the end wall panel, and a hook (41) to engage an edge of the web joining the roll-over flap to an end panel of the cover. In one embodiment of a cover, crushed areas (61, 62) are formed in the cover to provide a depression for receiving an edge of the end flap panels, and in another embodiment, a cover lock tab (73) extends downwardly from the end walls of the cover for engagement in hand hold openings (80) in the ends of a container.
