  • Patent number: 4522618
    Abstract: Apparatus for forming a tapered, nestable leakproof container having a bottom wall integral with front and back panels and side panels and a triangular connecting panel between additional panels extending from the front and back panels and the side panels, wherein the apparatus comprises a die and a tapered mandrel for forcing a blank through the die. The container blank is positioned on a support immediately above the die and held in position by guides on the support. Before the tapered mandrel engages the blank, glue is applied to the outer edges of the side panels of the rear wall of the container at the inner surfaces adjacent the outer edges of side panels connected to the rear panel and at the inner surface adjacent the outer edges of the side panels. The blank is forced into the die by the tapered mandrel. Appropriate pressure rollers resist the entry of the mandrel and move outwardly as the mandrel moves into the die moving the blank into the die.
