A dome for an aerosol container, comprising at least one raised pedestal having a flat top and a bottom and a dome cover, each pedestal containing a centrally located orifice and a substantially vertical side portion interrupted by a centrally directed indentation for crimping with the dome cover, the dome cover extending across the tops of the pedestals and having vertical sides which extend downwardly from the top of the pedestals to the bottom of the pedestals and are crimped to the sides of the pedestals, the dome cover following a downward and outward path from the bottom of the raised pedestals to end in an exterior depression having an outside edge, from the outside edge of the depression the dome cover rising vertically forming an exterior wall, turning sharply outwardly forming a ledge, and curving downwardly and inwardly forming a skirt.

A combination of a dome having an inner edge and a valve housing for an aerosol container wherein the dome is made of metal and the valve housing is made of plastic, the combination being prepared by an overmolding process so that the inner edge of the dome is embedded in the valve housing and the dome curves downwardly and outwardly to end in an exterior depression having an outside edge, from the outside edge of the depression the dome rises vertically forming an exterior wall, turns sharply outwardly forming a ledge and curves downwardly and inwardly forming a skirt, the dome being of such a size as to be capable of covering the top opening of the container.

A one-piece bag for an aerosol container, the bag having a central axis, a neck, and a body, wherein the neck is prepared by injection molding and the body is prepared by blow molding.

A method of preparing a bag for use in an aerosol container, which comprises:

• presenting a single piece of thermoplastic material, injection molding a portion of the thermoplastic material to form a bag neck and blow molding the remaining thermoplastic material to form a bag body.

A filling machine for filling and pressurizing aerosol containers having multiple valves, comprising a filling head having lower filling stems, which filling head and stems contain conduits for carrying materials to be dispensed.

A method of filling an aerosol container containing multiple valves with outlet openings, and at least one bag for material to be dispensed, comprising providing a filling machine comprising a filling head having lower filling stems, which filling head and stems contain conduits having lower outlet openings for carrying materials to be dispensed, which conduits will abut 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 with 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.

A static mixing device for aerosol containers having a center and multiple plunger outlets, comprising a first static mixing component and a dispensing component, the first static mixing component comprising multiple vertical inlet conduits which will abut with the plunger outlets of the containers, multiple horizontal conduits which extend forwardly and inwardly from the vertical inlet conduits to meet at a common inlet opening, an oval conduit which extends from the common inlet opening to a first outlet which is partially occluded by a column, a circular conduit containing multiple columns which extends from the first outlet rearwardly to a single central conduit containing additional columns, which central conduit extends forwardly to a central outlet opening and the dispensing component comprising a central inlet opening which extends vertically upwardly from the central outlet opening of the static mixing component to a horizontal outlet conduit which extends forwardly to an outlet orifice.

A combination of a pressurized aerosol container containing materials which should be kept apart during storage, but be mixed at the time of dispensing and a static mixing device, which pressurized aerosol container comprises multiple compartments for storage of the materials to be dispensed, a conduit leading from each compartment to a vertical inlet conduit of a static mixing component of the static mixing device, the static mixing component having a horizontal conduit leading from each vertical inlet conduit to a common inlet opening wherein the materials are combined, an oval conduit which extends from the common inlet opening to a first outlet, a circular conduit extending from the first outlet to a single central conduit which extends to a central outlet opening, a central inlet opening of a dispensing component of the static mixing device, extends from the central outlet opening of the static mixing component to a vertical outlet conduit, and a horizontal outlet conduit extending from the vertical outlet conduit to an outlet orifice in the dispensing component, wherein there are multiple columns in the conduits of the static mixing component.
