ABSTRACT:
The corrugated container is provided with internal reinforcing panels to form corners of increased thickness, thereby augmenting the stacking strength of the container. Locking tabs are formed in either vertical endwalls or in horizontal lid panels of the container and are interlocked with the reinforcing panels being folded between overlapping reinforcing panels. Locking slots are provided in the carton sidewalls and locking flaps have ear portions engagable with edges of the locking slots, to hold the lid panels in a closed position.
