Abstract:
A rifle-muzzle launched payload delivering projectile, comprising:(a) a launch tube defining an interior cavity, and having an opening at one end with an inner diameter sized to fit over the end of a muzzle of a rifle; (b) a bullet trap fixedly located in said launch tube cavity opposite from the launch tube opening, said bullet trap adapted for safely capturing a bullet fired from said muzzle; and (c) a payload assembly mounted on said launch tube opposite from said opening end, said payload assembly further configured for safely releasing a payload associated therewith in a controlled manner during delivery in absence of shrapnel formation or fragmentation, and wherein said payload assembly further comprises: (i) a casing having a distal end and a proximal end, said casing defining a chamber adapted for retaining an aerosol composition; (ii) a propellant housed in a reservoir in said casing for generating an expandable gas into said chamber upon ignition thereof; (iii) a primer for igniting said propellant; and (iv) a frangible portion of said casing in contact with the aerosol composition, said frangible casing portion adapted for safely rupturing in a controlled manner under pressure generated by said propellant after ignition, whereby an aerosol cloud is expelled and released into the atmosphere therefrom.
