Abstract
A carton having a bottom panel comprised of two overlapping flaps. The outer flap has a primary male tab engaging a primary female locking edge in the inner flap, while the inner flap has a secondary male locking tab engaging a secondary female locking opening in the outer flap. The secondary locking tab is connected to the carbon along a fold line coinciding with the fold line connecting the inner flap to the adjacent side panel, allowing a large secondary locking tab to be used even though the bottom panel is narrow. The outer and inner flaps are able to overlap across substantially the full width of the flaps to form a bottom panel of double thickness.
