Abstract
A flat sheet of box material has fold lines demarcated thereon for forming the sheet into a rectangular box for containing and protecting articles. Inflatable air pouches are secured to portions of the sheet which become the inner walls of the top, bottom and sides of the box. Air passages communicate the pouches with each other and an air vale enables simultaneous inflation of the pouches after the box has been filled and closed. Assembly of boxes at factories or elsewhere is facilitated as it is not necessary to insert liners or add other cushioning material at that time.
