The can may be filled with at atmospheric pressure and then shipped while the can contains approximately atmospheric pressure. Upon receipt of the can, a user may charge the can with a compressed gas and repeat charging if needed after some of the product has been dispensed. ## Claims ### Claim 1 A method for filling and using a product in an aerosol can, comprising the steps of: a. filling a product into a container positioned within a can at atmospheric pressure; b. shipping the can after the filling step (a) while the can contains approximately atmospheric pressure; c. interlocking the can to a compressed gas delivery system such that an interlock condition is satisfied; d. charging a compartment within the can with a compressed gas from the gas delivery system after the shipping step (b) and after the interlock condition is satisfied, the compartment being a space outside of the container; and e. charging the can after a portion of the product has been dispensed after the charging step (d). ### Claim 2 (depends on 1) The method of claim 1, wherein the can includes a bottom, a sidewall, a top, and a dispensing valve affixed to the top. ### Claim 3 (depends on 2) The method of claim 2, wherein the bottom includes a reusable grommet or a filling valve. ### Claim 4 (depends on 1) The method of claim 1, wherein the can is any one of a drawn and ironed metal can, an impact extruded metal can, a metal can having a longitudinal welded seam and a seamed-on bottom, and a plastic container. ### Claim 5 (depends on 4) The method of claim 4, wherein the metal can comprises aluminum or steel. ### Claim 6 (depends on 1) The method of claim 1, wherein the can is pressurized to less than 6 bar. ### Claim 7 (depends on 1) The method of claim 1, wherein the can is pressurized to between 2 and 5 bar. ### Claim 8 (depends on 1) The method of claim 1, wherein the can is pressurized to approximately 3 bar. ### Claim 9 (depends on 1) The method of claim 1, wherein the can is configured such that during shipping DOT-2P and DOT-2Q shipping regulations do not apply. ### Claim 10 (depends on 1) The method of claim 1, wherein the compressed gas comprises a propellant gas. ### Claim 11 A method for delivering product in an aerosol can, comprising the steps of: a. filling a product into a container positioned within a can at atmospheric pressure; b. shipping the can after the filling step (a) while the can contains approximately atmospheric pressure; wherein a compartment within the can is adapted for being charged with a compressed gas after the shipping step (b) and after the can is interlocked with a compressed gas delivery system such that an interlock condition is satisfied, wherein the compartment is a space outside of the container; and the compartment within the can is adapted for being recharged after a portion of the product has been dispensed after a first charge. ### Claim 12 (depends on 11) The method of claim 11, wherein the can includes a bottom, a sidewall, a top, and a dispensing valve affixed to the top. ### Claim 13 (depends on 12) The method of claim 12, wherein the bottom includes a reusable grommet or a filling valve. ### Claim 14 (depends on 11) The method of claim 11, wherein the can is any one of a drawn and ironed metal can, an impact extruded metal can, a metal can having a longitudinal welded seam and a seamed-on bottom, and a plastic container. ### Claim 15 (depends on 14) The method of claim 14, wherein the metal can comprises aluminum or steel. ### Claim 16 (depends on 11) The method of claim 11, wherein the can is pressurized to less than 6 bar. ### Claim 17 (depends on 11) The method of claim 11, wherein the can is pressurized to between 2 and 5 bar. ### Claim 18 (depends on 11) The method of claim 11, wherein the can is pressurized to approximately 3 bar. ### Claim 19 (depends on 11) The method of claim 11, wherein the can is configured such that during shipping DOT-2P and DOT-2Q shipping regulations do not apply.
