  • Chair base shipping carton
    Patent number: 5263582
    Abstract: A shipping carton for five legged chair bases is disclosed. The shipping carton is hexagonal with rectangular sides and four obtuse corner angles and two acute corner angles. The configuration of the carton allows for more efficient loading of a standard truck trailer or other shipping vehicle. In addition, the load has more stability and structural integrity than pentagonal cartons previously used for shipping five legged chair bases. The shipping carton of the present invention is economically formed from a single flat sheet of foldable material such as corrugated paperboard.
