Abstract
Abstract Each of the four panels, and the upper and lower flaps associated therewith, of a shipping carton incorporate a full height foldable section which enables a selective reduction in the length and/or width of the carton, in conjunction with an increase in the rigidity of the carton and without affecting the ability of the flaps to close and seal the opposed ends of the carton.
