Abstract
A corner post construction fashioned from corrugated paperboard of single or more thickness. The corner post is made from a unitary blank of corrugated paperboard, the blank being generally rectangular and provided with three parallel slit scorelines running generally longitudinally of the blank. The scorelines define four generally rectangular panels, with the two innermost panels being of substantially the same width, but with the first and second outermost panels being of respectively greater and different widths. The slit scorelines are reverse cut, with the middle coming in from one surface of the unitary blank and the outer two slit scorelines coming in from the other surface. All three scorelines extend completely through the blank, except for the outermost or facing layers of the corrugated board. After slit scoring, the two outermost panels are glued to their respective next adjacent innermost panels to form the corner post in its storage or shipping condition. For use, the panels are opened and an abutment takes place between an edge of one of the two outermost panels and the other outermost panel to automatically limit rotation to 90 degrees.
