A one piece substantially rectangular corrugated paperboard blank is folded into a comparatively shallow tray type container for packaging a plurality of relatively tall bottles of potable liquid in a compact relatively immovable non-wobbling cluster so that the packages may be stacked one upon the other. A top panel has portions scored and cut from each other to form reinforcing inner end parts and a vertical center panel which forms a bridge across the tray to keep the sides from spreading and it also forms a dunnage bulkhead between the halves of the bottles to cushion them from each other in a tight condition within reinforcing corners which embrace the bottles securely.
