Blast-Resistant Container With Sliding Door And Nested Structure

The patent implements a nested structure where an inner container is placed inside an outer container. The inner container provides the primary blast-resistant containment, while the outer container provides additional protection and structural support. This nesting approach allows the system to achieve high blast resistance without requiring the entire outer structure to be equally thick and heavy, thereby reducing overall weight while maintaining protection capability.

The patent employs composite construction by combining different materials and structural elements - the inner container, outer container, and various structural components between them. This composite approach allows optimization of each layer for specific functions, achieving high strength-to-weight ratio by using appropriate materials in each zone rather than uniformly thick construction throughout.

The patent divides the blast-resistant container into multiple separate components - inner container, outer container, door assembly, and structural elements. This segmentation allows each component to be manufactured independently using standard fabrication processes, reducing the need for expensive custom fabrication of a single monolithic structure. The modular components can be assembled using conventional joining methods, significantly lowering manufacturing cost while maintaining blast resistance.

The nested configuration of inner and outer containers allows for standardized manufacturing of each layer, which can be produced separately and then assembled. This approach reduces manufacturing complexity and cost compared to creating a single complex thick-walled structure, as each nested layer can be optimized and fabricated using appropriate standard processes.

By segmenting the container into modular components (inner container, outer container, door assembly), the patent enables the system to achieve large containment volume while maintaining manageable weight for each individual component. This segmentation allows the container to be transported and positioned more easily compared to a single monolithic structure of equivalent volume, as components can be handled separately and assembled on-site.

The nested structure allows the inner container to be placed within the outer container, maximizing the use of available space and achieving efficient volume utilization. This configuration provides large containment capability while the modular nested components can be transported and assembled more readily than a solid block of equivalent volume, improving accessibility and deployability.
