Abstract: A shipping, storing and dispensing container for a length of longitudinally- and radially-compressible product such as insulated or uninsulated duct for air conditioning systems. The container is adapted to have a lateral dispensing opening formed therein for allowing a desired length of compressed flexible duct or other similar product contained therein to be controllably drawn from the container, and to prevent such product from springing out of the container as a result of its internal compressive forces. The lateral dispensing opening is formed in one side and near one end of the container by punching out a flap defined by partially die-cut lines along one side and near one end of the container. The flap may be frictionally engaged with the edges of the container forming the lateral dispensing opening to close the lateral dispensing opening and re-seal the container.
