Container for containing explosive device and blast containing panel therefor

Abstract

A container for containing an explosive device, including an outer shell and blast containing panels disposed against inner surfaces of the outer shell to substantially define an enclosure. Each blast containing panel includes a fragment-retaining layer and at least one mitigating layer facing the enclosure. Each mitigating layer includes a cell structure having an outer wall connected to the fragment-retaining layer and a cell walls extending from the outer wall and forming cells having one end closed by the outer wall and an opposed end open, a blast effect mitigating material received within the cells, a fabric layer disposed against and sealing the open end of the cells, a mesh layer overlaying the fabric layer, and a frame forming a perimeter surrounding sides of the cell structure. The mitigating layer reduces a blast wave force and the fragment-retaining layer resists a remainder of the blast wave force and retains fragments.

Description

TECHNICAL FIELD[0001]The present specification relates to explosion containment, and more particularly to a container allowing safe transport of at least one small explosive device and to blast containing panels for such containers.BACKGROUND OF THE ART[0002]Small explosive devices such as detonators, detonating cord, airbag inflators and fuses are widely used and often need to be carried in the presence of others, including the general public.[0003]Upon detonation, rapid combustion processes produced even by a small explosive device compress surrounding fluid media so quickly that shock waves are produced. Also, the physical expansion of the hot blast combustion products adds to pressure loading of objects in its path, as well as generates radiation. The hot blast combustion products are typically capable of igniting combustible materials nearby and inflicting burns on exposed humans. Humans may be killed by intense blast pressure alone, as this causes lung damage above threshold l...

AI Technical Summary

Benefits of technology

This patent describes a container for holding an explosive device, which includes a multi-layered system to reduce the force (blast wave) of the explosion. The container includes an outer shell with a movable cover and blast containing panels that are securely closed to prevent any blast waves from escaping. The panels have a layered structure that includes a cell structure with cells filled with blast effect mitigating material, a fabric layer, a mesh layer, and a frame. The mitigating layer is designed to lessen the force of the blast wave, while the fragment-retaining layer is designed to hold fragments of the explosion. The technical effects of this invention include the reduction of danger and injury caused by blast waves, as well as the safe and secure containment of explosive devices.

Problems solved by technology

Upon detonation, rapid combustion processes produced even by a small explosive device compress surrounding fluid media so quickly that shock waves are produced.

Also, the physical expansion of the hot blast combustion products adds to pressure loading of objects in its path, as well as generates radiation.

Humans may be killed by intense blast pressure alone, as this causes lung damage above threshold levels.

Below threshold conditions for fatal injury, blast pressure may cause damage to ears and lungs, and sudden accelerations that lead to spinal injuries.

Moreover, fragments from exploding cased explosive devices may lead to fatal internal damage.

Large obstructions such as buildings surrounding a street in which a blast occurs prolong pressure durations and lead to greater damaging capability.

As a result, such containers are usually destroyed when the elements contained therein explode, and components are hurled at significant velocities.

As such, these containers would be unsuitable for transportation of small explosive devices next to people, as the components projected by the explosion could cause serious injury.
