ABSTRACT:
A single piece corrugated paperboard blank is cut and scored to provide a field erectable container without the use of any additional elements for locking pieces together. The container is one having inclined side walls so that the produce, such as asparagus or green onions, which is stacked in a vertical orientation may be packaged and held in place during shipment. The bottom of the erected container is larger than the top and an integral opposed strapping arrangement is provided whereby a plurality of flaps or panels are arranged to be folded into an orientation and locked in place to provide a field erected container which has great vertical stacking strength. Sufficient cooling vents are provided as are opposed hand holds. Upstanding stacking tabs are also provided so that one packed container may be stacked atop another and be substantially held in place.
