Abstract
Abstract A fiberboard container for the shipment of fragile and irregularly shaped articles includes a top tray, a bottom tray and, in some cases, a protective sleeve between the trays. Each of the trays has cavities to hold the articles, the cavities being formed in a pad of the tray. Each of the trays is constructed with a top pad and a bottom pad, which pads may be of laminated paperboard panels, and spacers of laminated fiberboard, to separate the top pad from the bottom pad.
