System and method for a reusable dispensing container

A reusable dispensing container assembly, comprising:

• a canister having a first end and a second end, said canister having an upper chamber to hold dispensable substance;
• an actuator arranged proximate said first end of said canister, in communication with said chamber, said actuator having a nozzle arranged to eject said dispensable substance;
• a deformable piston arranged within said canister below said upper chamber, said piston further arranged to sealingly engage an inner surface of said canister, said piston arranged for upward movement within said canister when said actuator is actuated, said deformable piston forming a lower chamber arranged to hold pressurized gas, said deformable piston comprising at least one integral external O-ring about its circumference arranged to sealingly engage said inner surface of said canister and maintain separation of said dispensable substance and said pressurized gas;
• and,
• a pressurization station having a pressurizing and de-pressurizing needle, said needle having a rounded tip, said pressurization station operatively arranged to pressurize said canister to permit upward movement of said deformable piston when said actuator is actuated to dispense said dispensable substance through said nozzle;
• wherein said pressurization station is operatively arranged to depressurize said canister to permit downward movement of said deformable piston when said deformable piston is positioned at the apex of said upper chamber of said canister.
