A storage and dispensing system for viscous fluids using a single aerosol container having a multi-valve body wherein the valves are activated by a single actuator and viscous materials are kept separate until used. The system may use multiple collapsible bags, a barrier liner, a dip tube, and an omnidirectional valve. Novel mounting cups lacking conventional central pedestal portions are disclosed. New domes for containers are disclosed which eliminate the need for mounting cups. New static mixing devices are disclosed. The devices are made up of static mixing components and static dispensing components. New filling machines for aerosol containers are disclosed. The filling machines contain a plurality of conduits for the separate viscous materials. Filling heads having nozzles depress the actuators of the containers and fill the containers.

1. A filling machine comprising a filling head having multiple lower filling stems having vertical axes which are laterally spaced apart, which filling head and stems contain conduits for carrying materials to be dispensed, wherein the filling machine is configured for filling and pressurizing aerosol containers having multiple valves, which valves have laterally spaced-apart vertical axes. 2. The filling machine of claim 1, wherein the filling head has an overhang, the filling head is surrounded by a collar located beneath the overhang, and there is a spring located between the overhang and the collar to bias the collar downwardly so that the collar will abut with the container and hold the container stationary. 3. The filling machine of claim 1 wherein there is a conduit for carrying pressurizing fluid located in the filling head. 4. A method of filling an aerosol container containing multiple valves with vertical outlet openings having laterally spaced-apart axes and at least one bag for material to be dispensed, comprising providing a filling machine comprising a filling head having multiple lower filling stems having vertical axes which are laterally spaced apart, which filling head and stems contain conduits having lower outlet openings for carrying materials to be dispensed, which conduits will about with plungers of the valves of the container, aligning the stems of the filling head above the appropriate valves, bringing the filling head downwardly so that the openings of the filling stems of the filling head connect the outlet openings of the plungers of the valves of the container, and passing the materials to be dispensed from the filling machine to the aerosol container. 5. The method of claim 4, wherein the filling head an overhang, the filling head is surrounded by a collar located beneath the overhang, and there is a spring located between the overhang and the collar, bringing the collar of the filling head into contact with the container, and applying downward pressure on the container to hold the container in place. 6. The method of claim 4, wherein the filling head of the filling machine further comprises a conduit for pressurizing fluid, the container contains multiple pre-expanded bags for the material to be dispensed, and the filling stems of the filling head depress plungers of the valves of the container to expel the air from the pre-expanded bags, the container is pressurized with pressurizing fluid entering the container through the pressurizing conduit of the filling head, and the bags are charged with material to be dispensed.
