Abstract
The embodiments of the present invention provide a blank of foldable material that configured to form a container. When formed, the container is completely self-locking. Additionally, when the blank is formed with any number of known liquid-proof sheet material or coatings, the container provides a leak/sift proof structure. Also, the container provides for all inside surfaces to be smooth, flat and interrupted surfaces. Further, as the hand hold cutouts are covered by end panels, the container retards hot or cold inside temperature degradation, which make the container ideal for use as a low-cost cooler or the like.
