  • Patent number: 8950332
    Abstract: A non-lethal, hand or rifle fired grenade which widely disperses non-lethal pellets—using a flexible multipocket bladder type device which is mounted on a rigid internal frame. The grenade provides a wide distribution arc of rotation for the pellets, as the pellets are located in pockets about the bladder, which is blown outward to expel the pellets. Further, as the propellant is located within the flexible multipocket bladder, the hot gases and embers cannot escape—thereby helping to protect the target individuals from exposure to such potentially hazardous materials.
