Abstract
A container is made in a collapsed configuration with bellows fold corners for self erection. Outer end wall panels are joined to the container bottom, leading to horizontal ledge panels and inner end wall panels fold over and down to lock via tabs into openings in the bottom. Columns reside under the ledge panels and are provided by column forming panels folded inwardly and glued to the inner end wall panels. Fold lines define the corners of each column and bear against inner sides of the front and back walls holding the columns open. The column forming panels have protruding tabs back by corresponding tabs on one of the ledge panels betwen the inner and outer panels of the end walls. These tabs form a two thickness registration tab that engages a corresponding opening in the container bottom for stacking.
