ABSTRACT:
A tubular corrugated paperboard shipping container having a rigid base frame, a cleat-reinforced tubular corrugated paperboard body attached thereto, and a top frame. The corrugated paperboard body includes a pair of spaced-apart attaching strips fixed on opposing side wall panels of the body. One of the pair of attaching strips on each panel is disposed in alignment with a member of the base frame. The other one of the pair of attaching strips is positioned on the panel in alignment with the top frame. Staples driven through the paperboard wall and the attaching strips secure the paperboard container to the base frame and to the top frame to ensure against component separation, thereby providing a cleated container with improved structural rigidity. A plastic sheet in the top frame prevents dust and dirt from entry into the container.
