The invention relates to pallets with integral collapsible Gaylord-type containers made of nylon, and useful methods for their preparation and use.
Transport and storage pallets and containers made of plastic are widely used in national and international trade. These pallets and containers protect and carry their contents during storage and transport, and there is a growing need for durable pallets and containers that efficiently maintain the quality of their contents.
One especially useful transport and storage container is the pallet with collapsible containers using a structural platform pallet made of metal, wood, or plastic materials. Wooden pallets and collapsible containers have been around for several years used, but their production and maintenance make them unwieldy and expensive. In addition, wooden pallets and collapsible containers have limited useful life due to adverse weather and can fail due to rotting when they are wet. In addition, wooden pallets and collapsible containers are assembled by fastener means such as glue, nails, or staples. Harsh weather conditions also accelerate the decline of these fasteners leading to failure of the wooden pallets and collapsible containers.
The potential for insect infestation also presents a growing need to treat wooden pallets and collapsible containers created before export. For nearly twenty years, the European Union has required heat treatment or chemical treatment for all unprocessed wood pallets and collapsible containers made from conifers. Freight transport on wooden pallets and collapsible containers that do not meet these requirements are rejected at the border. It is even more likely is that such non-compliant wooden pallets with Gaylord type containers are destroyed at the expense of the shipper.
Metal pallets and collapsible containers also have problems. Typically, they are expensive, heavy, and susceptible to corrosion.
Plastic pallets and collapsible containers, including High-density Polyethylene (“HDPE”), present possible flammability issues and related problems. If fire occurs, plastic pallets and collapsible containers are susceptible to flow, resulting in molten plastic leads, whereby the heat and fire spreads. The National Fire Protection Association has issued Forced Regulations that the usefulness of plastic pallets and collapsible containers to reduce these hazards. These Regulations impose that plastic pallets and collapsible containers have a composition comprising a thermosetting resin, which may be an epoxy resin, and a plurality of thermoplastic resins. These compositions may contain, for example, flame retardants. One known approach is constructions of polyvinylchloride pallets having a polyolefin upper deck and a polycarbonate or polyphenylene lower deck. Other approaches employ a polyolefin/halogenated epoxy pallet and collapsible container composition, where the halogenated epoxide acts as a flame retardant, optionally combined with a second flame retardant. These retardant regulations impose the expense of one or more of these additional and complex manufacturing component chemical subparts.
Another limitation for goods stored and transported on pallets and collapsible containers internationally are that the specific goods are not trackable, monitored, or accounted for between a shipping port and a receiving port of entry.
Finally, a further limitation for goods stored and transported on pallets and collapsible containers internationally are that during transport or storage the specific goods are subjected to extreme environmental conditions that degrade or spoil the transported goods with no means for alerting the sending party, the transporting party, or the receiving party of these conditions during storage and transport.
Thus there is a need for an improved pallet and collapsible container constructed of nylon that is durable and that overcomes the many limitations of existing metal, wood, and plastic pallets and containers.
There is yet a further need for an improved pallet and collapsible container construction of nylon that provides a low profile, high weight capacity product with pallet jack, forklift, and pallet equipment (PE) access from all sides through openings within the pallet portion so the improved pallet and collapsible container can be used with most material handling equipment including forklifts, pallet jacks, PE, and palletizers and other standard material handling equipment used in the art.
There is a further need for an improved pallet and collapsible container constructed of nylon rated to have a “no flashpoint” rating by either Underwriting Laboratories or nylon manufacturers making nylon a natural fire-resistant material eliminating any need for fire retardants. Constant re-evaluation of carcinogens in fire retardant means for plastic pallets and collapsible containers under the Environment Protection Act make plastic pallets and collapsible containers potential targets for recalls for the fire-retardant chemicals. The improved nylon pallet and collapsible container overcomes this limitation of plastic pallets and collapsible containers and makes the improved nylon pallet and collapsible container suited for the food and pharmaceutical industries.
A further need for an improved pallet and collapsible container constructed of nylon is using only recycled nylon for the improved nylon pallet and collapsible container manufacture, thus greatly decreasing the environmental carbon footprint of such durable improved pallets and collapsible containers. The nylon pallets and collapsible containers would also be recyclable into new nylon pallets and collapsible containers at the end of each improved nylon pallet's useful life cycle.
There is yet a further need for an improved nylon pallet and collapsible container that includes data collecting capabilities using RFID/GPS hybrid cellular based tags and/or sensors for temperature and environmental gasses such as carbon dioxide for data transmission during storage and transport, and use of other block-chain technologies, to maximize pallet platform and data potential, to meet the needs of shippers, transporters, and recipients, and to fulfil governmental regulations and industry standards.
A further need exists for an improved nylon pallet and collapsible container capable of accepting custom designed removable locking casters providing more flexibility where forklifts, pallet jacks, or PE cannot access or move pallets in tight spaces. This feature allows pallet interlinking to enhance forklift utility in pulling multiple loads at a time saving forklift trips. Locking casters also allow movement of heavily loaded pallets on a warehouse floor without the need of forklifts, pallet jacks, or PE.
