CONTAINER FOR LOCALISATION OF BLAST EFFECTS OF EXPLOSION Russian patent published in 2008 - IPC F42D5/04 F42B39/00 

FIELD: explosion engineering.

SUBSTANCE: container contains a body with a lid and a chamber being mounted therein with a gap between said chamber and body and a cavity for a detonating mechanism. The lid and the body walls are gas-permeable and the chamber consists of at least three concentric spherical or coaxial cylindrical perforated shells being placed one into another with a gap between them and made of metal or polymer materials. The shells are disconnectable and connectors of adjacent shells are positioned in mutually perpendicular planes. The gaps between the adjacent shells of the chamber as well as between the chamber and the body are filled with a gas-permeable material, while the chamber shells, the container body and lid have various degrees of perforation. The degree of perforation of the shells decreases from the centre of the container to its periphery.

EFFECT: invention allows to avoid damage to the personnel and to localize the explosion effect.
