US12480753 - Method and assembly for containing a hazardous object

A containment assembly comprises a first enclosure comprising a cavity for receiving a hazardous object. The first enclosure is configured for containing an explosive event of the hazardous object. A second enclosure comprises a gas impermeable layer, an inner volume, and an air-tight closure. The second enclosure is configured for receiving and containing a gas byproduct of the explosive event from the first enclosure. A gas permeable barrier is disposed between the cavity of the first enclosure and the inner volume of the second enclosure. A smart insulation arrangement may be implemented on the lower side of the first enclosure to allow the event to happen and to cool down over a longer period of time without exceeding maximum allowable temperatures on the outside of the second enclosure. This permits the flight or journey to continue.

The patent describes a containment assembly designed to safely manage explosive events from hazardous objects, featuring a first enclosure to contain the explosion and a second enclosure to trap gas byproducts. It includes pressure relief valves to prevent damage to the gas impermeable layer and a gas permeable barrier for effective separation between the two enclosures.

Claim 1

1 . A containment assembly comprising: a first enclosure comprising a cavity for receiving a hazardous object, the first enclosure configured for containing an explosive event of the hazardous object; a second enclosure comprising a gas impermeable layer, an inner volume, and an air-tight closure, the second enclosure configured for receiving and containing a gas byproduct of the explosive event from the first enclosure, wherein pressure relief valves are integrated with the second enclosure to avoid the gas impermeable layer from ripping; and a gas permeable barrier disposed between the cavity of the first enclosure and the inner volume of the second enclosure. a first enclosure comprising a cavity for receiving a hazardous object, the first enclosure configured for containing an explosive event of the hazardous object; a second enclosure comprising a gas impermeable layer, an inner volume, and an air-tight closure, the second enclosure configured for receiving and containing a gas byproduct of the explosive event from the first enclosure, wherein pressure relief valves are integrated with the second enclosure to avoid the gas impermeable layer from ripping; and a gas permeable barrier disposed between the cavity of the first enclosure and the inner volume of the second enclosure.
