ABSTRACT:
An improved collapsible, reusable shipping container is disclosed which is particularly usable for transportation of freight by air which is formed of a paperboard material having a high strength-to-weight ratio which is covered with a moisture sealing external coating to minimize weather damage thereto. The container is fully collapsible and includes door panels easily opened and closed to facilitate placement and removal of baggage or other cargo articles therein. An arcuate roof structure is provided to minimize the possibility of puddling or other such water damage to the top surface of the housing. The container can include one or two sets of doors which overlap one another and are retained from outward movement by vertically extending retaining straps when the container is in the loaded configuration.
