The invention claimed is: 1. A packaging machine former to engage an upwardly projecting locating spigot of a packaging machine, the spigot including a gas outlet, the former including: a base having a socket to receive the spigot so that the former is located thereby with respect to the machine; a former member over which strip bag material passes to be configured into tubular bag material, the former member providing a generally vertically oriented product passage into which product is deposited for delivery into the tubular bag material; and wherein said base and member provide gas passages that communicate with the socket so to receive a gas from said spigot and deliver the gas to said product passage. 2. The former of claim 1, wherein said gas passages extend to said member so as to deliver the gas to said product passage. 3. The former of claim 2, further including a backing member extending downwardly from the base, and wherein said gas passages extend through said backing member to deliver said gas to the interior of the tubular bag material. 4. The former of claim 3, wherein the former is configured to engage a packaging machine having a pair of upwardly extending locating spigots, each spigot providing a gas outlet, and wherein said socket is a first socket, and said base has a second socket, with the sockets being positioned to each respectively receive a respective one of the spigots so as to receive gas therefrom, with the gas passages communicating with each socket. 5. The former of claim 1, wherein the former is configured to engage a packaging machine having a pair of upwardly extending locating spigots, each spigot providing a gas outlet, and wherein said socket is a first socket, and said base has a second socket, with the sockets being positioned to each respectively receive a respective one of the spigots so as to receive gas therefrom, with the gas passages communicating with each socket. 6. A packaging machine including a mounting upon which a packaging former is to rest so as to be supported thereby, and wherein said mounting includes an upwardly extending spigot to be received by the former to locate the former with respect to the machine, said spigot including a gas passage to which a gas is delivered to the former, and a moveable valve member operatively associated with the passage so as to be moveable between a first position closing said passage, and a second position permitting gas to pass through said passage, said moveable valve member being urged to the first position and moved to the second position upon engagement with the former. 7. A packaging machine former to engage an upwardly projecting locating spigot of a packaging machine, the spigot including a gas outlet, the former including: a base having a socket to receive the spigot so that the former is located thereby with respect to the machine; a former member over which strip bag material passes to be configured into tubular bag material, the former member providing a generally vertically oriented product passage into which product is deposited for delivery into the tubular bag material; a backing member extending downwardly from the base, and wherein said base, former member and backing member provide gas passages that communicate with the socket so to receive a gas from said spigot and deliver the gas to said product passage, with said passages extending through said backing member to deliver said gas to the interior of the tubular bag material. 8. The former of claim 7, wherein the former is configured to engage a packaging machine having a pair of upwardly extending locating spigots, each spigot providing a gas outlet, and wherein said socket is a first socket, and said base has a second socket, with the sockets being positioned to each respectively receive a respective one of the spigots so as to receive gas therefrom, with the gas passages communicating with each socket.
