  • Patent number: 12151868
    Abstract: A fire-safe container includes a polymer polymeric IBC within a metal overpack. The metal overpack includes a manway surrounding a plurality of ports. Each port is on a projection form the polymeric IBC that extends into the manway through an aperture. A collar is disposed in each aperture between the projection of the polymeric IBC and the sides of the aperture such that the port is retained in the manway and preventing the port from contacting or collapsing through the aperture. The manway includes a burst disc to release pressure when there is pressure buildup. One of the ports can provide another burst disc to relieve pressure in the polymeric IBC. The polymeric IBC burst disc can release at a pressure that is greater than the pressure at which the manway burst disc releases.
