A compressed gas cartridge dispensing system capable of dispensing at least
two different capacities of non-threaded neck compressed gas cartridges as
well as optionally dispensing all cartridges having a 3/8-24 neck thread.
The standard 12-gram CO.sub.2 non-threaded neck compressed gas cartridge
fits this dispenser. The same dispensing system is also capable of
dispensing larger capacity cartridges having a neck dimensioned smaller
than a 3/8-24 female thread minor diameter with a water capacity in the
range of 16 to 50 ml. Obvious advantages to the dispensing system are
added options offering increased versatility for harnessing compressed gas
cartridges of differing capacities in a unique dispenser including a novel
cartridge storage feature.
