  • Patent number: 4059221
    Abstract: A shipping container is provided which is formed from a blank of foldable sheet material. The container includes a top closure flap which is foldably connected to the upper edge of one of four side panels. The closure flap has a shape which corresponds substantially to the area delimited by the upper edges of the side panels. Foldably connected to a peripheral segment of the closure flap is a finger pull tab which is disposed a substantial distance from the connection of the flap to the side panel. The finger pull tab facilitates initially moving the closure flap from a closed position to an open position. A first pair of alternate bottom closure flaps is foldably connected to corresponding side panels. Each of the first pair of bottom closure flaps is provided with a locking tab which is interlockingly accommodated within an elongated slot formed in a bottom closure flap which is one of a second pair of alternate bottom closure flaps.
