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.

A collapsible shipping container, especially adapted for the transportation of freight by air, is formed of material that inherently possesses a high degree of strength in relation to its weight and may, to this end, be constructed primarily of heavy-duty corrugated paperboard or the like. The container is fully collapsible to a flattened condition. Incorporated in the container is a special capability for retention of door panels in both their folded and their outwardly swung, use positions. This characteristic is imparted to the container structure by the use of flexible loops adjustable as to size. One of these is threaded through openings of one door panel, while the other is similarly connected to another door panel so as to travel therewith between the folded and extended or use positions of those panels. The other door panels are provided with slots, so that the loops can separably engage adjacent panels both in the collapsed and use positions of the container.
