Full Description:
BACKGROUND OF THE INVENTION 
   The present invention relates to an identity preserved (“IP”) container. In particular, to an IP container with a frame supporting an enclosure with a liner forming a bin terminating in a centrally located belly door. 
   Recent advances in biotechnology have revolutionized the agricultural industry, and in particular grain production. The proliferation of a wide variety of bio-engineered and genetically modified crops and food products provides unprecedented opportunity for farmers to achieve larger profit margins though production of niche products, especially compared to the economics of traditional grain products. Realization of the profits associated with these specialty grains, however, requires identify preservation of the grain throughout the distribution chain. In other words, from the farm to the factory the specialty or IP grain cannot co-mingle with other grains if the farmer expects the end users to pay a premium for the product. 
   In addition, with regard to genetically modified organisms (“GMO”) certain jurisdictions ban the importation of GMO crops, or limit the use of the crops in a manner that requires segregation of GMO grains from other grains. 
   As the technology of bio-engineering continues to evolve grain products the trend toward specialty grains will continue to grow, which will continue to transform what once was a fungible commodity into a product that requires special handling and segregation. 
   The traditional distribution methods applied to grains simply do not accommodate IP grains. At nearly every step of the established process grain is co-mingled. For example, during harvest, wagons or trucks offload the grain from the harvester for transportation to a local community grain elevator. In many cases, the wagons or trucks may contain grain from other sources, and almost certainly contain grain dust or pollen from other sources. Furthermore, the elevators handle large quantities of grain from over a fairly large region. Next, the elevator typically dispenses the grain to a larger truck or railcar for further transportation. For overseas transportation the grain is loaded into very large cargo holds of ships with grain from throughout the country. At each of these steps, substantial co-mingling takes place in a manner that makes IP movement completely impossible. 
   Containerization comprises one transportation option that that has greatly reduced the time and costs of shipping products over great distances, but heretofore has not been adopted for transportation of grains. Until the mid-1960s, cargo traveling by truck, rail, and ship traveled in essentially a haphazard and random manner. The lack of standardization made shipping cargo expensive and labor intensive. The introduction of standardized shipping containers, facilitated by the development of pallets and modem fork lifts, made it possible to greatly decrease the time and costs involved in shipping all types of cargo, including small items and delicate cargo. The development of intermodal containers made it possible to use one standard sized container to ship cargo by rail, truck, and by ship. The containers are large and can thus carry large amounts of cargo, they can be stacked, and can be moved from one transportation type to another without the need for disturbing the underlying cargo. In addition, the containers can be sealed to protect the cargo from contamination, and from other associated hazards. Thus, the proliferation of standardized containers has dramatically improved the art of cargo transportation. 
   Traditional standardized containers, however, are not particularly well suited for the transportation of grains, and transportation of IP grains in particular. Typically, the containers are side or end loaded and due to the fact that grain by its nature is a flowable material, this makes loading difficult. Furthermore, unloading grain is also difficult. The container must be tipped so that the grain can flow out of the side or end doors, and even this will not remove all of the grain and/or pollen from the container. Thus, shipment of IP grains in conventional standardized containers would require cleaning and decontamination of the containers before each reuse. 
   Accordingly, a need exists for a convenient transportation device that preserves the identity of the product or substance transported.

   DETAILED DESCRIPTION OF THE INVENTION 
   In the Figures,  FIG. 1  shows an IP container  10  that consists of a modified standardized intermodal container. The dimensions and construction of standard containers are well known in the art. In the preferred embodiment of the invention the container is 6058 mm×2500 mm×2591 mm (length×width×height) in external dimension, and 5880 mm×2420 mm×2387.5 mm in internal dimensions. This inner cubic capacity is 34 m 3 . Of course, these dimensions can and will vary depending on the application. In the preferred embodiment of the invention the IP container  10  is manufactured from an existing container, however, those of ordinary skill in the art will understand that the invention is not so limited. In particular, the IP container  10  could be specifically manufactured in a manner that would eliminate the need for modification. 
   The IP container  10  includes a bottom  12 , side walls  14 , back wall  16 , doors  18 , and a top  20 . In the preferred embodiment of the invention the doors  18  are welded shut to preserve an airtight inner storage cavity. The interior of the IP container  10  includes a lining that takes the general form of a funnel bin. In particular, the lining includes tapered funnel panels  22  supported by a plurality of funnel braces  25 . The funnel panels  22  form an angle  23  of forty-five degrees (see  FIG. 6 ). The liner includes side panels  24 . The liner is constructed of polyboard, or other similar type no-stick material. Polyboard is commercially available from commercial suppliers like McMasters-Carr of Elmhurst, Ill., and is typically made of sheets of polypropylene. 
     FIG. 6  shows the joint between the side panels  24  and the funnel panels  22 . The funnel panels  22  are supported with funnel braces  25  and with angle brackets  34 . In addition, angle brackets  34  support the joint between the side panels  24  and the funnel panels  22 . The side panels  24  terminate at a tapered side panel joint end  27  the meets the funnel panels  22  flush. The joint between the side panels  24  and the funnel panels  22  is then poly extrusion welded in place. In this manner, the joint between the side panels  24  and the funnel panel  22  will prevent cargo from inadvertently logging in the joint between the panels  24 ,  22 . 
     FIG. 4  depicts the method of attaching the side panels  24  to the side walls  14  of the IP container  10 . A metal fastener  48  is attached to the side wall  14  with weldments, or similar attachment means, wherein the head of the fastener  48  is captured within a recess  50  in the side panel  24 . A poly cap  52  is secured over the recess  50  and poly extrusion welded in place to maintain a non-stick surface on the side panel  24  to prevent inadvertent capture of any portion of the IP container  10  cargo. The side panels  24  are attached to the side walls  14  of the IP container  10  at regularly spaced intervals to provide for secure attachment. 
     FIGS. 2 and 3  depict the belly door  26  that lies at the bottom of the funnel formed by the funnel panels  22 . The belly door  26  lies in a 3′×2′ opening in the center of the bottom  12  of the IP container  10 . The belly door  26  comprises a first plate  28  made of ½″ thick poly board and a second plate  30  made of ¼″ steel. A channel  32  runs the length of two opposing sides of the belly door  26 . The belly door  26  moves between a closed and an open position by moving in the channel  32 . Angle brackets  34  attach to the top and inside portions of the channel  32  to form a joint between the first plate  28  and funnel plates  22 . Rubber seals  36  runs the length of the channels  32  between the first plates  28  and the bottom of the angle brackets  34  to prevent cargo from collecting in the channel  32 . Slats  54  made of polyboard fit between the second plates  30  and the bottom of the channels  32  to capture the lower portion of the belly door  26 . The area between the inward sections of the angle brackets  34  form a well 1¾″ deep. In addition, the belly door  26  includes opposing racks  40  that run the length of the underside of the belly door  26 , for use in moving the belly door  26  between a closed and open position. 
     FIG. 3  shows the mechanism  38  for moving the belly door  26 . The mechanism  38  includes spur gears  42  aligned with the racks  40 , which connect to a shaft  44 . The shaft  44  is captured by pillow bearings  46 . Two of the pillow bearings  46  attach under the belly door  26  to a portion of bracing  56  that runs along the bottom  12  of the IP container  10 . The other pillow bearing attached to an end of the bracing  56  near toward an outside edge of the bottom  12  of the IP container  10 . A crank (not shown) attaches to the shaft  44  at the outside edge to allow for manually moving the belly door by rotating the crank. The belly door  26  is sized to fit between adjacent brace member  56  of the IP container, and moves in a direction perpendicular to the brace members  26 . 
     FIG. 5  shows an embodiment of the invention that utilizes a compartment wall  58  located within the interior of the IP container  10 . The compartment wall  58  creates a partition to allow for segregating the IP container  10  into a plurality of sections. The compartment wall  58  comprises a liner essentially identical to the liner described hereinabove, except that the three liner panels  24  attach to each other with fasteners  48  to form the compartment wall  58 . The compartment wall  58  components are also comprised of polyboard. A piece of rectangular tubing  64  supports the compartment wall  58  above a plurality of support braces  62  placed along and under the rectangular tubing  64 . Angle brackets  34  provide support at the joint between the side panels  24  and the funnel panels  22 , and at the transition between the top of the compartment wall  58  and the top  20  of the IP container  10 . Each compartment or section created by the compartment wall(s)  58  would include its own belly door  26 . 
   The top  20  of the IP container  10  includes a plurality of sealable hatches  60  through which cargo enters the IP container  10 . The top  20  creates an airtight seal in the IP container  10 , except for opening the hatches  60  and belly doors  26 . 
   In the preferred embodiment of the invention a conventional intermodal standardized container is converted into the IP container  10  according to the following method. The first step involves removing the floor of the container, typically made of plywood, to expose the bottom bracing including the center brace. A hole for the hatch is cut in the top, wherein each compartment includes one hatch located directly over the center of each compartment. Working from the back compartment forward toward the container doors, the belly door is located in the bottom center of each compartment. The belly door channels are welded in place to the existing center most braces in each compartment. The remainder of the belly door is then constructed between the channels. The mechanism for moving the belly door is then constructed by aligning the spur gears with the rack welded to the bottom of the belly door. The pillow bearings are then placed in the manner shown and described hereinabove. A 2″ hole can be placed in the lower portion of the side wall to allow for inserting the crank onto the shaft for moving the belly door. 
   Next, the liner is constructed. Measuring the distance from the edge of the belly door to the walls comprises an easy method for determining the length of the funnel panels, in that this distance is the same as the length of two sides of a right triangle, of which the funnel panels forms the hypotenuse. This will ensure a forty-five degree angle. This distance is marked on the side walls of the container, and angle brackets are welded to the side walls in the orientation shown in  FIG. 6 . The funnel braces are then placed on the bottom of the container, angle brackets can be used to support the bottom of the braces. The funnel panels and side panels can then be cut and secured in place. Compartment walls are then constructed by first welding 2″×2″ angle brackets to the 3″×1″ rectangular tubing at regular spaced intervals, as shown in  FIG. 5 . The rectangular tubing is then welded to the side walls of the container at the appropriate height, and supported by three support braces. The funnel panels can be put in place on the various compartments, this will allow for assembly of the three piece center compartment walls from the back of the container to the front. Prior to placing the center compartment walls in place, 2″×2″ angle brackets are welded to the each side wall and top of the container to allow for mounting the upper corners of the center compartment walls. The angle brackets include predrilled holes for this purpose, this allows for using stainless steal bolts to mount the center compartment walls to the angle brackets. Additional side panels and funnel panels are attached to each compartment in the manner described above. The final step in the process is to enter the container from the open belly door and extrusion weld all of the seams. The container doors, if not already sealed, can be sealed at this time as well. 
   Configured in this manner, the IP container comprises an airtight self-contained transportation device suitable for moving cargo that requires complete segregation. In particular, the IP container is preferably designed for the transportation of IP grains like corn, soybeans, wheat, sorghum, rice and the like, and for processed material such as sugar. The top-loading hatch makes for convenient loading of flowable material like grains, and the belly door allows for easy unloading of the same substances. The very slick surfaces of the liner allows the cargo to flow out of the interior of the IP container on unloading, and the special construction prevents the retention of even small amounts of the cargo. This substantially eliminates the need for special cleaning and sterilization of the IP container between uses. The IP container is airtight, which allows for loading cargo in a specified moisture condition and maintaining that condition until the cargo arrives at its destination. Once the cargo is loaded into the IP container, it is sealed and not disturbed until it arrives at its ultimate destination. In this manner, the problems associated with prior art transportation systems is substantially eliminated, especially as those problems relate to cargo that requires identity preservation. 
     FIG. 8  shows a perspective view the uncovered IP container  10 . In this embodiment of the invention, the inner storage cavity of the container  10  includes four steel reinforcement support panels  65 . The support panels  65  are made of ¼″ steel plate that fasten and reinforce and support the underside of the poly board funnel panels  22  located inside the container  10 . The funnel panels  22  can be made of any commercially available thermoplastics such as polypropylene and ABS that are tough and impact resistant. Two rows of 2″×2″×¼″ angle iron frame  66  that run the length of the each of the support panels  65  are attached generally in the middle of the each of the support panels  65 . The joint between the suport panels  65  is poly extrusion welded in place. The angle iron frame  66  is similarly welded to the support panels  65  to form a stable entity. The support panels  65  are secured to the floor  12  of container  10  by a plurality of vertically orientated square tubing supports  25 . The 2″×2″×⅛″ square tubing supports  25  vertically extend from the floor  12  of container  10  to connect with the angle iron frame  66 . Three evenly spaced square tubing supports  25  are connected along the side of each support panel  65  to the angle iron frame  66 .
