  • Patent number: 11125390
    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.

  • Patent number: 10745185
    Abstract: The present invention relates to a flame retardant shipping container for lithium ion batteries, and more particularly for containing a thermal runaway event. The shipping container comprising an outer box, preferably made of flame-retardant corrugated fiberboard, containing a vacuum plenum/thermal shield assembly and a tray and a first flame-retardant pouch. The assembly comprising an inner container on a thermal shield inside a metalized vacuum bag. The inner container further comprises an inner cavity and an opening and a second flame-retardant pouch. The assembly rests on the tray. The pouches contain molecular sieves and palladium plated microsphere catalysts. The thermal shield has an aluminum foil surface and is filled with thermal paste. The tray is preferably flame-retardant molded paper pulp and forms at least two pockets separated by flame-retardant molded pulp separators. The tray is separated from the outer box by an air gap containing the first flame-retardant pouch.
