DEFENSIVE DEVICE, MAINLY SELF-DEFENSIVE DEVICE AND CARTRIDGE CASE USED IN IT Russian patent published in 2006 - IPC F41B9/00 F41H9/10 F42B5/145 

FIELD: means of self-defense.

SUBSTANCE: the cartridge case has a spraying unit, solid, gaseous and/or liquid operative substance kept in an accumulating chamber, starting charge, ignition charge for ignition of the starting charge with the aim of ejection of the operative substance from the accumulating chamber through the spraying unit to the environment. In the area of the spraying inlet provision is made for a cut-off member, which in the non-ignited state prevents outlet of the operative substance from the accumulating chamber, however, after ignition it frees the spraying unit so that parts of the spraying member cannot penetrate from it. The accumulating chamber has a piston installed for motion due to the working gases from its initial position to the working gases from its initial position to the final position for ejection of the operative final position for ejection of the operative substance. A means of unloading from pressure is engageable with the piston, after a complete ejection of the operative substance it causes a complete removal of pressure of the working gases. At least two cartridge cases may be installed together in the self-defensive device. The self-defensive device has a symmetry plane, relative to which one cartridge case is symmetrically positioned, and an actuating mechanism with a single actuating pusher with the aid of which the operative substance respectively of one cartridge case is ejected to the environment with the preset configuration of distribution. The actuating pusher is in the symmetry plane.

EFFECT: enhanced reliability of operation of the self-defensive device.
