1. A siphon head, providable in two separate mutually attachable parts, for dispensing a liquid from a pressurized container, said container having an interior storage space for containing a liquid and a threaded neck, said siphon head comprising (a) a cap assembly, comprising i) a generally cylindrical shell defining an interior cap space and having threads thereon positioned and sized in diameter and pitch to engage said threaded neck of said container to removably attach said cap assembly to said container;ii) a siphon tube having a proximal end and a distal end, wherein the distal end of the siphon tube reaches into said interior storage space of said container when said cap assembly has been attached to said container, and said siphon tube has an interior passage therein operable to flow said liquid from said container in response to a pressure drop at the proximal end of said siphon tube;iii) a valve disposed in said cap assembly, said valve being attached to the proximal end of said siphon tube so as to be in closed fluid communication with said interior passage of said siphon tube, said valve further providing an openable seal, said seal further being actuatable to open and thereby cause a pressure drop at the proximal end of said siphon tube in response to a force applied to said valve, said valve being biased in a normally closed position;(b) an actuator assembly removably attached to said cap assembly, comprising i) a housing having a fitting for securely engaging an exterior fitting of said cap assembly to removably attach said housing to said cap assembly, andii) a unitary actuating member movably attached to said housing, said actuating member comprising an ejector nozzle and a vertical tubular portion integrally formed with an actuating lever and an actuator rod, wherein said actuating member is configured to move between a first position, where said actuator rod is not in contact with said valve and said valve is closed, to a second position, where the actuating member engages said valve to exert a force on said valve to cause said valve to open, and wherein said ejector nozzle and actuating lever are integral with one another to move together relative to the siphon tube when the actuating member is moved from the first position to the second position, wherein the cap assembly further comprises a transversal partition having an axial bore surrounded by an annular channel and a bottom free end of the actuator rod is aligned with said bore and the open end of the vertical tubular portion is aligned with the annular channel in a manner that said bottom free end and said open end are spaced apart from the bore and channel, respectively, in the first position of the actuating member and in a manner that said bottom free end is passing through said bore and pushing over said valve and said open end is in sealing engagement to said channel, in the second position of the actuating member. 2. The siphon head of claim 1, further comprising a safety interlock comprising a breakable annular strip at a bottom edge of a cylindrical outer wall of said cylindrical shell and projecting retaining members to lock against a neck of said container. 3. The siphon head of claim 1, wherein said valve is provided with a seat in said shell, said seat being in the form of a rib forming a seal for the contents of said container. 4. The siphon head of claim 1, wherein said fitting of the housing and said exterior fitting of the cap assembly comprise corresponding engageable threads. 5. The siphon head of claim 1, wherein said interior of cap assembly further comprises a cylindrical boss with a cylindrical inner wall for receiving said valve, and wherein said valve is fittable into said cylindrical inner wall of said cap assembly. 6. The siphon head of claim 5, wherein said valve is a cylindrical resilient piece, said resilient piece further comprising an inner passage having grooves therein for retaining said siphon tube. 7. The siphon head of claim 6, wherein said valve is fitted into said cylindrical inner wall of said boss of said cap assembly by a threaded fitting, wherein the interior of said cylindrical wall and the exterior of said valve have corresponding engageable threads. 8. The siphon head of claim 6, wherein said valve is fitted into said cylindrical inner wall of said boss of said cap assembly by a diameter restriction in said cylindrical inner wall and the body of said resilient valve has a diameter retainable in said restriction. 9. The siphon head of claim 1, wherein said valve is comprised of a resilient material and wherein said openable seal comprises a frustoconical axial bore in said shell of said cap assembly and a corresponding frustoconical sealing head in said valve. 10. The siphon head of claim 1, wherein said valve is comprised of a resilient material and wherein said openable seal comprises a sealing head in said valve, and the body of said valve further comprises a plurality of resilient ribs joining said body and said sealing head and defining a passage for fluid through said valve. 11. The siphon head of claim 3, wherein said valve is comprised of a resilient material and a sealing head, and wherein said valve further comprises a sealing shoulder around said sealing head for sealing against a valve seat formed within said valve, to form a seal for preventing fluid escape from said container. 12. The siphon head of claim 1 wherein said siphon tube is a tube for filling an empty container onto which said cap assembly has been threadedly attached and sealed. 13. The siphon head of claim 12 further comprising a safety interlock comprising a breakable annular strip at a bottom edge of a cylindrical outer wall of said cylindrical shell and projecting retaining members to lock against said container neck. 14. The siphon head of claim 1, wherein the shell of said cap assembly further comprises an annular ring concentric with and interior to said threads in said shell for forming a fluid-tight seal with the inner upper circumference of said neck of said container.
