System and method for a reusable dispensing container
A reusable dispensing container assembly, having a canister having a first end and a second end, the canister having an upper chamber to hold dispensable substance, an actuator arranged proximate the first end of the canister, in communication with the chamber, the actuator having a nozzle arranged to eject the dispensable substance, and, a deformable piston arranged within the canister below the upper chamber, the piston further arranged to sealingly engage an inner surface of the canister, the piston arranged for upward movement within the canister when the actuator is actuated, the deformable piston forming a lower chamber arranged to hold pressurized gas, the deformable piston comprising at least one integral external O-ring about its circumference arranged to sealingly engage the inner surface of the canister and maintain separation of the dispensable substance and the pressurized gas.
1. 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.
2. The reusable dispensing container assembly recited in claim 1 wherein said canister further comprises a valve arranged on said second end of said canister, said valve is arranged to accept said needle.
3. The reusable dispensing container assembly recited in claim 2 wherein said valve further comprises:
an upper split portion having two bills; and,
an interior cavity having a first portion defined by said upper spilt portion of said valve, said interior cavity having a neck portion, said interior cavity having a flared portion distally arranged in relation to said first portion,
wherein said flared portion of said interior space of said valve is arranged to accept said needle; and,
wherein said first portion of said interior space of said valve is arranged to accept said needle, said rounded tip of said needle is operatively arranged to spilt said bills of said upper split portion of said valve.
4. 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.
5. 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 engage said canister and create suction within said canister to pull said deformable piston distally in the direction of said second end of said canister.
6. The reusable dispensing container assembly recited in claim 1 , wherein said piston is hollow.
7. The reusable dispensing container assembly recited in claim 6 , wherein said hollow piston includes an internal cavity in communication with said pressurized gas, wherein said pressurized gas causes said piston to expand against an inner wall of said canister.
8. The reusable dispensing container assembly recited in claim 3 , wherein said needle of said pressurization station is arranged pressurize said canister by engaging said needle with an interior space of said valve.
9. The reusable dispensing container assembly recited in claim 3 , wherein said needle of said pressurization station is arranged depressurize said canister by engaging said needle between said two bills of said upper spilt portion of said valve.
10. The reusable dispensing container assembly recited in claim 7 , wherein said hollow piston includes a top surface having an aperture, said aperture arranged to removably accept a removal tool.
11. The reusable dispensing container assembly recited in claim 7 , wherein said hollow piston is comprised of a deformable material, said removal tool is arranged to engage said piston to forcibly remove by deformation said piston from an opening of said canister.
