Abstract
A manually operated self defense device comprising a manually operated pump driven propulsion chamber which can propel either a stream or spray at a potential attacker wherein the self defense device is characterized by the fact that no pre-pressurized gas or irritant canisters are used, and wherein the self defense device irritant or disabling storage container is not refillable by the user, and when used, the first pump action loads the propulsion chamber from a storage container, and thereafter, the propulsion chamber is always primed and ready for instant operation, and in as much as no pre-charged gas canisters are employed, there is no gas leakage, and reliability is greatly improved, resulting in a self protection device which is capable of providing multiple discharges without the loss of operating range, or effectiveness, and which contains an internal safety mechanism designed to prevent the attacker from turning the self defense device upon the user.
