This application claims the benefit of application Ser. No. 12/386,530 filed on Apr. 20, 2009.

BACKGROUND OF THE INVENTION

Large, enclosed steel marine shipping and transporting containers are used for a number of purposes. One particular container, the so-called intermodal marine shipping container, has been the standard container of the marine transportation shipping industry since its introduction by Malcolm Mclean and Sea Land Shipping over sixty years ago. These containers are hollow, six-sided boxes, fabricated almost entirely of welded mild steel corrugated sheets, or aluminum and/or non-recyclable fiberglass reinforced plastic (FRP), in very few cases, such as in refrigeration containers. The containers are constructed in accordance with International Standards Organization (ISO) standard marine transportation size lengths of twenty feet, forty feet, forty five feet, forty eight feet, and fifty three feet, heights between eight feet and nine and a half feet, widths of eight feet. They are also provided with uniform distance lifting eyes and structural design specifications.

Intermodal marine shipping containers are easily lifted, moved, and secured, so that they can be shipped by sea, air, or land. The containers, because they are typically manufactured from steel, are relatively heavy and have a high heat transfer ratio. They are labor intensive in their manufacture and assembly (almost 95% of all manufacturing being sent to low cost manufacturing countries), are prone to accelerated corrosion from sea (salt) elements, and are environmentally difficult to recycle. These steel containers are not capable of being scanned with present standard x-ray technology from the outside and, being steel, are incapable of accepting radio frequency (RF) transmissions without the use of exterior antenna.

Representative examples of prior art intermodal marine shipping containers are disclosed with regard to the prior art discussed below. However, these containers are mainly made of mild steel, aluminum, or connected fiberglass reinforced panels, and, in a number of variations, they are configured to be collapsible or reduced in size to provide space savings during storage and transportation. All such containers would fail to obtain ISO certification through rigorous ABS testing for static loading bearing capability, vertical corner loading, and the watertight integrity required for marine intermodal shipping containers. The containers also were not developed to provide a solution to the problems of RF permeability for internal and external transmissions.

U.S. Pat. No. 3,570,698 discloses a collapsible rectangular steel shipping container having opposed horizontally-hinged sidewalls which can be collapsed or folded inward and downward.

U.S. Pat. No. 3,877,602 discloses a collapsible steel container with improved fastener assemblies, formed from a plurality of lightweight, insulating panel members, each detachably secured together along their respective edges by fastener assemblies.

U.S. Pat. No. 5,190,179 discloses a collapsible framed, box type, waterproof shipping container including pivoting end walls and bi-folding side walls.

U.S. Pat. No. 5,865,334 discloses a self-contained, segmented, six-sided reusable container, including both an assembled form and a collapsed form. The sides and ends are interconnected while the container is in its assembled form.

U.S. Pat. No. 5,979,684 discloses a cargo container wherein at least two walls adjacent to each other are constituted using integrally formed FRP panels. The container has a sandwich panel including a core of plywood or polyurethane foam, and FRP skin as the main rigidity maintaining member.

U.S. Pat. No. 7,002,472 discloses a container configured for transporting cargo on a transportation vehicle A method for transporting the container on the transportation vehicle is disclosed. Disposed within the container housing is at least one detector for detecting security deviations and a communications link capable of transmitting the possible threat information to a central cargo data collection location.

U.S. Pat. Pub. No. 2004/0263329 discloses a container intrusion detection method and apparatus which emits a wireless signal within the container, detects the wireless signal near the container, and responds to detection of a change in a characteristic of the detected wireless signal by transmitting a wireless notification to a location remote from the container.

U.S. Pat. Pub. No. 2005/0046567 discloses a container and contents monitoring system which utilizes a monitoring device, a reader, a server, a software backbone and a receptacle for housing a plurality of sensors. The device communicates with the plurality of sensors and the reader in order to determine the condition of the container and its contents. The reader transmits the information from the device to the server. The device determines if a container abnormality has occurred, based on at least one of the sensors located on or in the container.

U.S. Pat. Pub. No. 2006/0016807 discloses a foldable, steel freight container, comprising a frame and other container components foldable for compactness.

U.S. Pat. Pub. No. 2006/0144837 discloses a segmented cargo carrying container which can be disassembled and thus collapsed.

None of the containers or container systems in the prior art addresses the many requirements and needs related to the law, economics, security, and practicality demanded in today's modern transportation shipping industry.
