Abstract:
1. A container for receiving an explosive element and containing fragments projected by an explosion thereof, the container comprising: a seamless enclosure made of walls defining a first open end and a first closed end , the seamless enclosure being collapsible, the walls are formed by a plurality of independent interleaved plies of material, the material and number of plies are selected to contain fragments projected by the explosion; an outer casing having a plurality of first and second panels defining a second enclosure for snugly receiving the seamless enclosure, the first and second panels being rigid, the first panels being hingedly connected to the second panels such that the first panels are movable between a first deployed configuration, where the first panels define a second open end corresponding to the first open end, to a second folded configuration, where the first panels at least partially close the second open end, thereby reducing a height of the outer casing; and a first attachment system on the outer casing for maintaining the first panels in the first deployed configuration when the container is receiving the explosive element; an inner casing snugly surrounded by the seamless enclosure, the inner easing having a plurality of third and fourth panels defining a third enclosure, the third and fourth panels being composed of a blast mitigation material significantly reducing a strength of a blast produced by the explosion before the blast reaches the seamless enclosure, the third panels being hingedly connected to the fourth panels such that the third panels are movable between a third deployed configuration, where the third panels define a third open end corresponding to the first open end, to a fourth folded configuration, where the third panels at least partially close the third open end thereby reducing a height of the inner casing; and a second attachment system an the inner casing for maintaining the third panels in the third deployed configuration when the container is receiving the explosive element; whereby the container is folded for storage by collapsing the seamless enclosure and moving the first panels of the outer casing in the second folded configuration, and the first panels of the outer casing can be moved in the second folded configuration at least when the third panels of the inner casing are in the fourth folded configuration.
