Abstract
A stackable container for carrying produce. The container has tapered side walls or end walls to aid in the stacking of like containers. Also, the container has locking flaps that allow the container to be erected manually and without the need for fasteners. Further, at least one tapered wall of the container has a reinforcement flap that creates a partial top structure in the upper part of the container that helps prevent bulging of the walls. The reinforcement flap also creates doubled stacking tabs and diagonal corner posts that aid in the stacking of like containers.
