Abstract
Abstract A blank for a carton for packing bicycles and other articles is formed from a rectangular piece of sheet material such as corrugated paperboard so as to save waste material. It is cut and scored so that it may be preliminarily formed into a tube to be shipped flat to the packager and, as it is being erected, so that integral portions and parts may be folded into strut columns extending from wall to wall in two directions to prevent the contained article from tilting or migrating inside the container during shipment and to strengthen the carton against the pressures of stacking and handling by clamp trucks and the like.
