  "abstract": "The present invention relates to containers and packaging materials, and more particularly to a container having a thermal barrier member for reducing the transfer of heat from and/or to the container. The shipping container preferably comprises an outer vessel with an O-ring and an inner vessel separated by an air gap. The inner vessel has a first and second wall and a lid assembly. The lid assembly has a top lid and a bottom lid and a thermal paste. A felt gasket is preferably positioned between the lid assembly and the first and second walls. The first and second walls comprise at least two relief valves. One relief valve is a Flame Arresting/Smoke Particulate Filtration/Chemical Adsorption Unit Assembly and the valve is bi-directional. The thermal paste is preferably a flowable polymer based heat-absorbing material. The shipping container is stackable on a registration plate with other containers.",
  "claims": [
    "1. A shipping container configured for shipping thermally active materials, the shipping container comprising: an outer vessel; an inner vessel with a first and second wall and a lid assembly, where the lid assembly comprises a top lid and a bottom lid and a superabsorbent polymer-based thermal flame retardant paste for preventing the spread of fires with temperatures exceeding 824° F.; and, where the first and second walls comprise at least two relief valves.",
    "2. The shipping container of claim 1 where there is an air gap between the inner vessel and outer vessel.",
    "3. The shipping container of claim 1 further comprising a felt gasket positioned between the lid assembly and the first and second walls.",
    "4. The shipping container of claim 1 where at least one relief valve is a flame arresting/smoke particulate filtration/chemical adsorption unit assembly.",
    "5. The shipping container of claim 1 further comprising a pallet base attached to the outside vessel.",
    "6. The shipping container of claim 1 where at least one relief valve is bi-directional.",
    "7. The shipping container of claim 1 where the outer vessel further comprises an o-ring.",
    "8. A plurality of shipping containers and at least one registration plate, each shipping container comprising: an outer vessel; an inner vessel with a first and second wall and a lid assembly, where the lid assembly comprises a top lid and a bottom lid and a superabsorbent polymer-based flame retardant thermal paste for preventing the spread of fires with temperatures exceeding 824° F.; and, where the first and second walls comprise at least two relief valves; where the plurality of shipping containers are stacked on at least one registration plate, where the at least one registration plate interlocks with the plurality of shipping containers.",
    "9. A shipping container configured for shipping thermally active materials, the shipping container comprising: a plurality of structural panels defining a container interior configured for receiving thermally active materials, and an exterior disposed adjacent to an environment in which the shipping container is placed, a thermal barrier member for placement between the thermally active materials and the environment in which a container is placed, the thermal barrier member including a thermal barrier interior panel and a thermal barrier exterior panel, where the thermal barrier interior panel and the thermal barrier exterior panel define a heat absorbing material receiving cavity; a flowable polymer based flame-retardant material for resisting temperatures exceeding 824° F. disposed within the heat absorbing material receiving cavity, wherein the thermal barrier member is configured to substantially surround the thermally active materials to prevent temperatures exceeding 824° F. from the thermally active materials heating the environment in which the shipping container is disposed to 824° F. or above; and, at least one pressure relief member for permitting pressure generated by the thermally active materials to be vented to atmosphere.",
    "10. The shipping container of claim 9 where the at least one pressure relief member comprises a flame arresting/smoke particulate filtration/chemical adsorption unit assembly."

  "description_excerpt": "The present invention relates to containers and packaging materials, and more particularly to a container having a thermal barrier member for reducing the transfer of heat from and/or to the container.\n\nWith the proliferation of electrically operated portable 1 gadgets,” the number of batteries sold to power these gadgets has mushroomed proportionately. One type of battery whose sales have increased dramatically over the past 10 years is lithium batteries. For example, it is estimated that about 4 million dollars of lithium batteries were sold in 1996, and that about 4 billion dollars in lithium batteries were sold in 2014.\n\nLithium batteries have advantages over the alkaline batteries that they usually replace. Because since lithium is a very active material, it tends to provide greater power relative to the amount of material used in a battery. Additionally, the lithium discharge curve is longer and flatter than alkaline, thus providing consistent higher voltage to the life of the battery.\n\nThese characteristics enable a gadget manufacturer to reduce the size of batteries of equivalent power required to operate the gadget, or alternately to provide a greater amount of power in a battery in a determined size.\n\nAlthough lithium batteries are more expensive than alkaline, they have especially good performance characteristics when used in small devices or those requiring a large amount of reserve power, such as cameras and smartphones.\n\nThe term “lithium battery” refers to a class of batteries that include cathodes or electrolytes that contain either metallic lithium or a lithium compound.",
