FIELD OF THE INVENTION

0002This invention is in the general field of a dunnage platform bag that is light weight, strong and made of a fire retardant material. The dunnage platform bag can accommodate a modified dunnage platform assembled from a dunnage platform base and legs attached to the base. The dunnage platform bag can form an ultra violet light, weather and dust barrier to protect the integrity of the dunnage platforms when not in use. A system and method for supplying, dispensing, positioning, tracking, transporting, forwarding and storing dunnage platforms based on the dunnage platforms bag is disclosed.

BACKGROUND OF THE INVENTION

0003The adoption of International Standardized Phytosanitary Monitoring (ISPM)-15 for wood packaging material (WPM) requires kiln dry treatment of all wood used in shipping crates and dunnage platforms (pallets). The United States in cooperation with Mexico and Canada began enforcement of the ISPM 15 standard on September 16, 2005. The North American Plant Protection Organization (NAPPO) strategy for enhanced enforcement will be conducted in three phases. Phase 1, September 16, 2005 through January 31, 2006, call for the implementation of an informed compliance via account managers and notices posted in connection with cargo that contains noncompliant WPM. Phase 2, February 01, 2006 through July 04, 2006, calls for rejection of violative crates and pallets through re-exportation from North America. Informed compliance via account managers and notices posted in cargo with other types of non-compliant WPM continues to remain enforce. Phase 3, July 05, 2006, involves full enforcement on all articles of regulated WPM entering North America. Non-compliant regulated WPM will not be allowed to enter the United States. The adoption of ISPM-15 reflects the growing concern among nations about wood shipping products enabling the importation of wood-boring insects, including the Asian Long homed Beetle, the Asian Cerambycid Beetle, the Pine Wood Nematode, the Pine Wilt Nematode and the Anoplophora Glapripwnnis.

0004Thus the wooden dunnage platform has become unattractive for the international shipment of products. Further, the wooden surface is not sanitary since it potentially can harbor in addition to insects, mould and bacteria. Thus, the wooden crate is generally illsuited for the shipment of foodstuffs and other produce requiring sanitary conditions.

0005Plastic dunnage platforms or pallets are known, see <patcit id="pcit0005" dnum="US3915089A"><text>U.S. Pat. No. 3,915,089 to Nania</text></patcit>, and <patcit id="pcit0006" dnum="US6216608B"><text>U.S. Pat. No. 6,216,608 to Woods et al.</text></patcit>, which are herein incorporated by reference in their entirety. Plastic pallet manufacturing techniques typically involve injection molding, which significantly increases the cost of the plastic pallets. In order to justify this initial investment cost of the plastic pallet, the pallet must be extensively reused. Thus, while the plastic surface of the plastic pallet obviates some of the sanitary problems with wood pallets, because of the required repetitive use the surface can become unsanitary. As a consequence when used for the shipment of foodstuffs and other produce requiring sanitary conditions, the high cost of the plastic pallet requires that the plastic surface be cleaned and kept clean prior to use.

0006Some wood pallet manufacturers have attempted to produce a more sanitary surface by combining foam with wooden surfaces. These dunnage platforms still suffer a number of disadvantages including their weight, the presence of wood requiring kiln treatment and the possibility of the foam being stripped away to expose the wood surface.

0007Thermoplastic molded dunnage platforms are known. <patcit id="pcit0007" dnum="US5833796A"><text>U.S. Pat. No. 5,833,796 to Dummett</text></patcit>, which is herein incorporated by reference in its entirety, which discloses applying thermoplastic sheets to a preformed rigid structure for manufacturing dunnage platforms.

0008<patcit id="pcit0008" dnum="GB2375096A"><text>GB 2375096</text></patcit> discloses a bulk bag for palletless transportation of goods. US RE38076 discloses a stackable pallet and a shipping container for a stack thereof.

0009Irrespective of the material used to make the dunnage platform sanitary, there remains a problem in the field of keeping sanitary dunnage platforms clean while they are being stored or otherwise not in use.

0010Further, irrespective of whether the dunnage platforms are made of wood, plastic, foam or thermoplastic, they are a source of fuel for a fire and thus represent a fire hazard. Storage of dunnage platforms after unloading, either inside or outside the delivery location increases the risk of a significant fire. Flame retardant materials are known, however, they have not been successfully incorporated into dunnage platform construction materials. Thus there is a need for a sanitary dunnage platform suitable for transporting foodstuffs, which is light, cheap and does not present a fire hazard. Since materials being shipped can also represent a fire hazard, while somewhat beneficial, it is not essential that the dunnage platform per se be fire resistant. However, there is a need for a method of storing, loading, dispensing and shipping empty sanitary dunnage platforms, which are light, inexpensive and not a fire hazard.

0011Optiledge™ feet are lightweight, strong, phytosanitary, molded feet in an L-shape designed to attach to the bottom of a crate or shipping unit and which can act as a transport device. Optiledge™ can in some circumstances be used as an alternative to a wood pallet for loading and shipping units. When the product to be shipped contains a deck, Optiledge™ can be made integral to the packaged product and can act as a pallet during the storage and distribution of the packaged product. Optiledge™ or any similar device is not appropriate when the unit load does not include a deck surface onto which the Optiledge™ type device can be mounted

SUMMARY OF THE INVENTION

0012The invention provides a dunnage platform bag system as disclosed in claim 1 and a system of monitoring location, condition and status of cargo loaded on dunnage platforms as disclosed in claim 15. In one embodiment of the invention, a dunnage platform bag is disclosed that is light weight, strong, made of a fire retardant material and which forms an ultra violet light, weather and dust particle barrier to protect the integrity of the dunnage platforms when not in use. In addition, a system and method for loading, storing, dispensing, positioning, tracking, and transporting empty dunnage platforms based on the dunnage platform bag is disclosed.

0013In an alternative embodiment of the present invention, a dunnage platform with damaged feet is modified such that the feet can be removed and replacement feet can be attached. In an embodiment of the present invention, the damaged feet of a dunnage platform can be removed and Optiledge™ feet can be attached to the dunnage platform deck. In another embodiment of the invention, a dunnage platform deck with stubs is manufactured and molded feet are press fitted into the stubs or otherwise attached to the dunnage platform deck. In various embodiments of the invention, the modified dunnage platforms can be loaded into the dunnage platform bag.

0014This summary is not intended to be a complete description of, or limit the scope of, the invention. Other embodiments of methods for manufacturing a dunnage platform and repairing the legs of damaged dunnage platforms, within the scope of the invention, can be understood by a person having ordinary skill in the art. Alternative and additional features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

DETAILED DESCRIPTION OF THE INVENTION

0016In one embodiment of the invention, a manufacturer makes a commitment to an airfreight cargo forwarder of a cargo lift volume contract in return for supply of thermoplastic dunnage platforms to resolve ISPM-15 issues and other advantages such as cargo safety, human safety, convenience and resolving fire risk issues involved with storage of flammable dunnage platforms. Client agrees to pay shipping freight cost as would be incurred with wood pallets. In return the manufacturer makes a commitment of sufficient thermoplastic dunnage platforms for shipping the cargo. The airfreight cargo forwarder who assigns manufacturing capacity to clients requires a balancing commitment from the client of a cargo lift volume contract. The airfreight cargo forwarder saves between 17 and 33 % of the total freight cost of shipping the cargo (after subtracting the cost of the thermoplastic dunnage platforms), while solving clients ISPM-15 concerns.

0017In an embodiment of the invention, a dunnage platform manufacturer (hereinafter 'manufacturer'), shipping forwarder (hereinafter `forwarder') and manufacturer with cargo to ship (hereinafter 'client') co-operate to ship a client's cargo without ISPM-15 concerns at a reduced cargo freight cost, thereby producing a useful concrete and tangible result. In another embodiment of the present invention, the manufacturer ships the thermoplastic dunnage platforms in a fire retardant bag which the client can use to hang and store the dunnage platforms thereby saving space while eliminating a fire hazard and thereby producing a useful concrete and tangible result. In an alternative embodiment of the present invention, the manufacture supplies dunnage platforms with RFID tags thereby allowing the forwarder to track the shipment while en route thereby producing a useful concrete and tangible result.

0018Forwarders to provide dunnage platforms to their clients free of charge in exchange for retaining the financial benefit of weight savings, while giving their clients: (1) improved convenience, (2) cost of not having to buy pallets, (3) eliminating ISPM-15 issues, (4) improving cargo safety (5) improving human safety and (6) gaining greater contracted cargo volume from clients.

0019Manufacturer production facilities are: (1) remarkably portable and inexpensive, (2) easily deployed anywhere, and (3) able to produce up to 15,000 pallets per month. Factories can be readily placed in forwarders' market regions to service their local clients. No other competitive pallet production can match this scalability and the manufacturer manufacturing process is fully patented.

0020Each forwarder can secure exclusive "Agency" rights for a port or market region and pre-sell the full monthly production allocation of 15,000 pallets (per manufacturer machine) by consigning them free of charge to strategic clients in exchange for cargo lift volume contracts. When the first allocation is gonc, prc-salc of a second unit can bcgin until the major market clients can be fully sold on a first-option basis. This strategy removes all risks from the program rollout. Clients can be selected based on optimum profiles for cargo destinations, freight costs, type of cargo, size and importance of client and overall value of service the program provides to forwarder and client.

0021Revenues to forwarder can be calculated on a cargo weight savings basis of 40 pounds per pallet and pallet costs can be paid to manufacturer from those savings, leaving the cash balance to the forwarder. At $1 per pound, each pallet can yield $15 cash profit ($225,000 month) to the forwarder. At $0.75 pound, it can produce $75,000 per month, especially considering surcharges alone are reaching as much as $.80 per pound in some markets. The forwarder can have no cash risk, as manufacturer is paid $25 per pallet from the saving stream (following collection of client's invoices) and the remainder is held by the forwarder. The only investment of the forwarder is the cost of sales efforts to pre-sell the cargo region.

0022In one embodiment of the invention, the dunnage platform bag is a modular, lightweight, strong, ultra violet light insulating, fire resistant, tamper proof receptacle for storing, reloading, dispensing, tracking and transporting dunnage platforms. <figref idref="f0001">Figures 1</figref> and <figref idref="f0002">2</figref> depict an embodiment of the dunnagc platform bag invention in which the dunnagc platform bag is 30.5 m (120 inches) x 1.27 m (50 inches) x 1.07 m (42 inches) and weighs 3.2 kg (7 lb). In another embodiment, the dunnage platform bag includes a spreader and base. In other embodiments the dimension of the dunnage platform bag will vary depending on the dimension of the dunnage platform to be stored in the bag. In one embodiment of the invention, the dunnage platform bag consists of four sides a top and a bottom sewn together. In one embodiment of the invention, two parallel zippers separated by between approximately 52-78 mm (20-30 inches) can each sewn into one side of the bag and located on that side approximately 13 mm (5 inches) down from top of the bag and approximately 10 m (40 inches) from the bottom of the bag. In this invention, it will be understood by persons having skill in the art that the use of the term 'approximately' when used together with dimensions that indicate a preferred range can vary by up to 50% of the preferred range. In another embodiment of the invention, the zippers extend the full length of the bag. In another embodiment, a cord string is attached to the two zippers to enable both zippers to be opened or close simultaneously. In an alternative embodiment, Velero™ is used to rcscal one or more openings in the dunnage platform bag. In another embodiment, one or more re-sealable openings can be used for inserting, removing or inspecting the plurality of dunnage platforms.

0023<figref idref="f0001"><b>Figure 1</b></figref>, shows the dunnage platform bag holding 22 dunnage platforms (of dimension 1219 mm (48 inches) x 1016 mm (40 inches) x 139 mm (5.5 inches)) prior to stretching and hanging. <figref idref="f0001"><b>Figures 1</b></figref> and <figref idref="f0002"><b>2</b></figref> show that the dunnage platform bag material is sufficiently strong to allow handling of the fully loaded dunnage platform bag.

0024In one embodiment of the invention, the material of the bag is strong enough to allow the bag to be hoisted and the dunnage platform bag and transport base left hanging for dispensing. In an embodiment, of the invention thermoplastic molded dunnage platforms can be loaded in the dunnage platform bag. In an embodiment of the invention, the thermoplastic dunnage platforms have RFID tags inserted into the core prior to coating the core with the thermoplastic layer. A RFID reader mounted in the base or the spreader can then read the RFID tags in the individual dunnage platforms. In an alternative embodiment of the invention, plastic dunnage platforms can be loaded in the dunnage platform bag. In another embodiment, cargo loaded on one or more dunnage platforms can be inserted into the dunnage platform bag. In various embodiments, sufficiently strong material can be used and the seams can be strengthened to compensate for the additional weight of the plastic dunnage platforms or the cargo.

0025<figref idref="f0001"><b>Figure 1</b></figref> shows that the dunnage platform bag holding twenty-two dunnage platforms remains stable when the zippered bag is opened for manual insertion, removal or inspection of the dunnage platforms. <figref idref="f0002"><b>Figure 2</b></figref> shows the dunnage platform bag lying length wise on a surface holding a dunnage platform and two zippers open for manual insertion, removal and inspection of the dunnage platforms.

0026<figref idref="f0003"><b>Figure 3</b></figref> shows a perspective of the dunnage platform bag <b>300</b> attached to a transport base frame total height 3.267 m (128 11/16 inches). In an embodiment of the invention, the dunnage platform bag <b>320</b> has a top and four sides, where the four sides can be attached to a transport base, which forms the bottom side. In an embodiment of the invention, the transport base frame <b>350</b> has a flange attached to the inside of the frame which abuts the lowest dunnage platform (i.e., the dunnage platform in contact with the dunnage platform stop trigger 910) so as to seal the bottom of the dunnage platform bag. The flange is flexible enough to allow the dunnage platforms to be dispensed or reloaded while retaining sufficient rigidity to form a seal between the transport base frame 650 and the undercarriage or sides of the lowest dunnage platform in the stack of dunnage platforms loadcd in the bag. In various embodiments of the invention, the flange can be made of flexible rubber or plastic.

0027In <figref idref="f0003"><b>Figure 3</b></figref>, a spreader plate <b>310</b> has dimensions slightly larger than the length and width of the bag <b>320</b> to which it is attached through load binders <b>330</b>. In an embodiment of the invention, a hook <b>340</b> with plate submerged into the spreader plate <b>310</b> is used to hold the bag <b>320</b> upright.
