ABSTRACT:
A corrugated box has two side panels joined by parallel end panels. An automatic bottom panel extends from a side panel, and has two converging reverse-scored fold lines which extend between a side panel and the outer edge of the automatic bottom panel. End flaps are folded up from the automatic bottom panel and are connected to the end panels to form box side walls. One of the end flaps has a diagonal fold line, with portions of the flap above the diagonal fold line only being adhered to the end panel. The angles of the reverse scored fold lines are selected depending on the dimensions of the box to allow the automatic bottom panel to be deployed from a folded position alongside the side and end panels to an assembled position perpendicular to the side and end panels, simply by displacing one side panel with respect to the other. A strip of latex dry seal gum adhesive is applied to the box interior bottom panel, as well as to the box automatic bottom panel, such that when the box is erected the two strips overlie each other and form an adhesive bond, thereby increasing the box bottom strength. The two strips of adhesive are applied to opposing faces of the corrugated blank, and in the box collapsed condition are facing away from each other and are shielded on the inside of the collapsed assembly, being thereby protected from dust and other contamination to provided an extended adhesive life.
