Abstract
Abstract A rocking cradle is formed from a cut and scored blank of paperboard or the like. It is formed from foldably interconnected top, side and bottom panels. Both the top and bottom panels have extensions therefrom foldably connected along curved score lines, so that both the top and bottom panels, when folded and connected to define a tube, are curved in transverse cross-section. The top panel is cut and scored and foldable to position to define inner sides of the finished cradle, and extensions from the bottom panel define inner ends for the cradle. The cradle is characterized by the top panel providing end and side rails providing good structural integrity to the total structure.
