Backpack personal defense material dispenser

1. A backpack material dispenser, comprising:

a. a pumpless pressure tank for storing and discharging a material under pressure contained in the pressure tank;

b. a hose and a shut off valve connected to an output opening of the pressure tank for allowing flow of the material from the pressure tank under pressure and through a nozzle communicating with a discharge end of the hose;
