Abstract

A single-piece corrugated box suited for shipping one or more articles, e.g. hazardous articles such as cans of paint, varnish, solvent or other liquid hydrocarbon includes four upright side wall panels that are connected by vertical fold lines and upper and lower pairs of abutting, full-overlap article-stabilizing flaps that are provided with punched openings therein positioned in vertical alignment with each other so that one pair of stabilizing flaps surrounds and interlocks over the upper end of the article and the other pair of stabilizing flaps surrounds and interlocks over the lower end of the article. Each pair of stabilizing flaps is supported exteriorally by a pair of laterally opposed end flaps which are folded centrally so as to enclose and abut the ends of the article as well as the underlying stabilizing flaps. The stabilizing flaps are hinged to the side walls of the box by horizontal fold lines. These fold lines form opposed anchoring points for the stabilizing flaps which cooperate with the interlocking of the stabilizing flaps over the article to strengthen and rigidify the box to enhance protection of the article that is packaged therein. The stabilizing flaps both extend horizontally in a straight line toward the article from the side wall to serve as a shock- and pressure-resisting brace between the article being shipped and the side wall of the box.
