Abstract
Abstract A stackable carton having a lid and tray is formed from planar folded blanks of corrugated board. The tray has recesses on its lower end edges and tabs in alignment therewith on its upper end wall edges. The lid when assembled on the tray has openings aligned with the tray tabs such that the tabs pass through the lid and extend upwardly for receipt in the recesses in the lower end edges of a like carton stacked thereon.
