Abstract: A spray system for dispensing a homogenous mixture of a liquid formulation and propellant as an atomized aerosol where a fill cup containing a liquid base is connected to a charge can to pressurize the inside of the fill cup and to act as a propellant. The charge can is attached to the fill cup through a fitting in fluid communication with the interior of the fill cup, where the fitting may be configured to allow the pressurized charge can to be detached after adding a propellant compatible with the liquid base to the fill cup. Preferably the liquid formulation is a paint base that can be tinted at the point of sale before charging with the charge can.

Abstract: A spray system for dispensing a homogenous mixture of a liquid formulation and propellant as an atomized aerosol where a disposable container containing a liquid base is used alone or secured within a rigid container and is charged through a fitting in fluid communication with the interior of the disposable container using a detachable pressurized charge can containing a propellant compatible with the liquid base. Preferably the liquid formulation is a paint base that can be tinted at the point of sale before charging with the charge can.

Abstract: A system for charging pressurized aerosol cans with liquid is provided combining a disposable syringe and filling machine. The syringe is loaded with a liquid, then placed in the filling machine and connected to the inlet of the pressurized container. The filling machine is activated and an electric motor or a hydraulic piston exerts force on the syringe to inject the liquid into the aerosol container.

Abstract: A spray paint system for spraying a horizontal surface having a frame supporting an inverted elongated rigid container configured to hold a paint formulation that is pressurized with a pumping device partially located within the container where the frame has at least one wheel to allow a user to roll the system along a horizontal surface while spraying paint through a removable spray tip. This system can be used to mark a horizontal surface with precise and clear writing of lines, letters or symbols.

Abstract: A pressurized package contaning an initial paint formulation having a neutral or clear color is prepared by mixing a propellant and a clear non-pigmented base or a clear pigmented base or a white pigmented base in a pressurizable container. This pressurized container is then sold to retail stores where tints and/or pigment dispersions are injected into the pressurized container to arrive at a matched or selected final color and sold directly to the end user.

Abstract: An apparatus for charging pressurized aerosol cans with liquid is provided having a reservoir, filler coupling and safety release device. The safety release device automatically prevents over-charging the can by interacting with the safety dome to cause the can to disengage from the filling reservoir.

Abstract: Methods and apparatus are disclosed for a safety enclosure for an aerosol device that includes an overlying cap coupled to a base cap. There is also a tab on the overlying cap that prevents rotation of the overlying cap with respect to the base cap and keeps the caps locked and the underlying aerosol spray device in an inoperative position. When use of the aerosol spray device is desired, the tab is ripped away. The two caps may be rotated to either align or mis-align the openings on the caps to permit or prevent user actuation of the spray device.
