  • Patent number: 10329048
    Abstract: A stackable paperboard container is provided and includes a bottom panel, a pair of side panels, a pair of end panels, a pair of side flaps, and a pair of top walls. The pair of side panels extend from the bottom panel and are foldable about a side panel fold line. The pair of end panels extend from the bottom panel and are foldable about an outer end fold line. Each side flap extends from one of a pair of side panels and is foldable about a side flap fold line. Each top wall extends from one of pair of end panels and is foldable about a top wall fold line. Each top wall includes a wall section, a pair of top wall flaps, each top wall flap extending from one side of the wall section and foldable about by a top flap fold line, and a pair of bottom locking tabs, wherein each bottom locking tab extends from each of the pair of top wall flaps along a locking tab fold line and is insertable into a bottom tab slot of the bottom panel.
