Vessel having CO2 compressed gas source

摘要

The compressed CO2 gas source is an insert that can be fixed in a sealed manner in an opening of the vessel. The insert has a high-pressure CO2 cartridge, a pressure-regulating valve for discharging CO2 therefrom and a control element that is accessible from the outside and that can be actuated to pierce the high-pressure CO2 cartridge. The control element can be automatically interlocked and blocked against further actuation after it has first been actuated.
