1. A cowling for use with a container of pressurized gas having a central axis and a flow regulator mounted thereon, said flow regulator extending axially along said axis and having (i) a shut off valve, (ii) a pressure gauge and (iii) a fill port positioned at spaced intervals about said axis and facing away therefrom, said cowling being manufactured as an integral unitary one piece unit and including a lower engagement end, a wall portion extending axially upwardly from said engagement end to an upper end, said wall portion having (a) a first opening which, when the cowling is used with said container, is aligned with and provides access to manipulate said shut off valve of said container, (b) a second opening which, when the cowling is used with said container, is aligned with said pressure gauge of said container, wherein said second opening defines a generally Y-shaped configuration having a bottom edge, spaced upwardly from said engagement end, a pair of spaced apart lower side edges extending upwardly from said bottom edge substantially parallel to each other and, when the cowling is used with said container, to said axis, an upwardly and outwardly tapered edge extending from each of said lower side edges, a pair of spaced apart upper side edges extending upwardly from said tapered edges substantially parallel to each other and, when the cowling is used with said container, to said axis and a top edge extending between said upper edges and spaced downwardly from the upper end of said cowling and (3) a third opening which, when the cowling is used with said container, is aligned with and provides access to said fill port of said container. 2. A cowling in combination with a mounting ring and a container for pressurized gas having a central axis and a flow regulator mounted thereon, said flow regulator extending axially along said axis and having (i) a shut off valve, (ii) a pressure gauge and (iii) a fill port positioned at spaced intervals about said axis and facing away therefrom, said cowling being manufactured as an integral unitary one piece unit and including a lower engagement end, a wall portion extending axially upwardly from said engagement end to an upper end, said wall portion having (a) a first opening aligned with and providing access to manipulate said shut off valve of said container, (b) a second opening aligned with said pressure gauge of said container, wherein said second opening defines a generally Y-shaped configuration having a bottom edge, spaced upwardly from said engagement end, a pair of spaced apart lower side edges extending upwardly from said bottom edge substantially parallel to each other and to said axis, an upwardly and outwardly tapered edge extending from each of said lower side edges, a pair of spaced apart upper side edges extending upwardly from said tapered edges substantially parallel to each other and to said axis and a top edge extending between said upper edges and spaced downwardly from the upper end of said cowling and (3) a third opening aligned with and providing access to said fill port of said container, said container having a neck extending upwardly to an upper end and having inwardly facing threads defining an opening parallel to or lying on said axis and said mounting ring including a circular outer ring extending substantially parallel to said axis from a lower end to an upper end, said ring having inwardly facing threads, a bottom wall extending from the lower end of said ring inwardly toward said axis, a tapered wall section extending inwardly and upwardly from said bottom wall, said tapered section having a plurality of apertures, a top extending from said tapered wall section toward said axis, said top having a lower surface engaged to said neck upper end and a center hole in which is positioned said flow regulator, said flow regulator having outwardly facing threads engaged to said neck inwardly facing threads and having a shoulder clamping the lower surface of said mounting ring to said neck upper end. 3. A cowling in combination with a mounting ring and a container for pressurized gas according to claim 2 wherein said container neck has a recessed shoulder adjacent said inwardly facing threads and extending downwardly from said neck engagement surface and further including a gasket positioned in said recess shoulder, said flow regulator shoulder being in sealing engagement with said gasket. 4. A cowling in combination with mounting ring and a container for pressurized gas according to claim 3 wherein said gasket is formed of a fluoroelastomer material. 5. A cowling in combination with a mounting ring and a container for pressurized gas according to claim 2 wherein said tapered wall section is thinner in the area adjacent to said bottom wall than in the area adjacent said top. 6. A cowling in combination with amounting ring and a container for pressurized gas according to claim 2 wherein said top is below a plane defined by the upper end of said outer ring. 7. A cowling in combination with a mounting ring and a container for pressurized gas according to claim 6 further including a pair of raised areas or plates on said top, said raised areas or plates having straight edges parallel to one another on opposite sides of said center hole, said flow regulator having spaced apart surfaces adjacent the respective straight edges. 8. A cowling in combination with amounting ring and a container for pressurized gas according to claim 2 further including means for preventing rotation of said cowling relative to said mounting ring. 9. A cowling in combination with amounting ring and a container for pressurized gas according to claim 8 wherein said means for preventing rotation comprises an aperture in said outer ring and a screw or rivet in said aperture engaged to the wall portion of said cowling.
