Abstract
A filling system for an electronic cigarette (10) is disclosed in which a nozzle (38) of a liquid dispenser (80) contains a plunger (62) which is biased by a spring (60) into a closed position in which liquid is prevented from flowing through the nozzle (38). In use the nozzle (38) is inserted into an open end (42) of a liquid reservoir (34) for an electronic cigarette containing an air tube (32). The plunger (62) engages with the end of the air tube (32) blocking the air tube (32) and opening the liquid flow path through the nozzle (38). The arrangement of the plunger (62) and nozzle (38) is such that operation of the plunger (62) only occurs when the nozzle (38) engaged within a liquid reservoir (32). A membrane (96) can be provided to prevent leakage from the liquid reservoir (34) when the nozzle (38) is disengaged.
