Shipping container

Abstract

A rectangular shipping container of corrugated cardboard in which the bottom is closed by first and second closure flaps hingedly connected to the lower edges of the side walls, and third and fourth closure flaps hingedly connected to the lower edges of the end walls. The first and second flaps are foldable inwardly to horizontal positions closing the bottom of the container in which their inner edges are closely spaced apart and define a channel. The third and fourth flaps are slotted and are foldable inwardly to horizontal positions in which they underlie the first and second flaps and their slots underlie the channel. A first retainer is slidable in the channel and in the slot in one of the slotted flaps, engaging the first and second flaps and the slotted flap to hold them in their horizontal positions. A second retainer is slidable in the channel and in the slot in the other slotted flap, engaging the first and second flaps and the other slotted flap to hold them in their horizontal positions. The retainers are slidable in the channel toward one another far enough to withdraw from the slots and then slidable out of the channel through either end thereof to release all of the flaps.
