Abstract
Abstract A shipping container of tubular form for shipping pipes and tubes of great length, being made of two blanks secured together. A first blank has five side-by-side panels each hinged to the adjacent panel(s) and a second blank of equal length has three side-by-side panels similarly hinged. The middle panels only are adhered together and in erected condition, each of the four walls of the container has the thickness of two panels. A method for making a shipping container includes producing multi-ply paperboard in indefinite lengths, cutting it into blanks of two different widths, cutting four V-notches in the wider blank and two V-notches in the narrower blank to produce a five panel and a three-panel blank, and then securing the middle panels together with the notches parallel and opening in the same direction.
