  • E-liquids are usually a mixture of propylene glycol, glycerin, nicotine, and flavorings.
  • E-cigarettes may provide nicotine by forming an aerosol of liquid particles. E-liquids without nicotine also exist.
  • E-cigarettes have been based on a cartridge system, wherein a user can exchange an empty cartridge with a new, full cartridge. Filling lines for filling these cartridges with the E-liquid (or liquid) have been developed.
  • the quantity of liquid that needs to be inserted into the cartridge is quite small.
  • the discharge nozzle of the filling device is inserted into the cartridge, ejects this quantity of liquid in the cartridge, and is subsequently retracted from the cartridge.
