Abstract

There is provided a cartridge assembly (2) for use in an aerosol-generating system, the cartridge assembly (2) comprising a cartridge (4), a cartridge cover (6) and a mouthpiece (8). The cartridge (4)comprises at least one compartment having an air inlet (16, 18) and an air outlet. The cartridge cover (6) is helicoidally moveable with respect to the cartridge (4) between a first position in whichthe air inlet (16, 18) is obstructed and a second position in which air may flow through the air inlet (16, 18). The mouthpiece (8) is helicoidally moveable with respect to the cartridge (4) betweena third position in which the air outlet is obstructed and a fourth position in which air may flow through the air outlet.

Description

technical field [0001] The present invention relates to a cartridge assembly for use in an aerosol generating system and an aerosol generating system comprising said cartridge assembly. The invention finds particular application as a cartridge assembly comprising a nicotine source and an acid source for generating an aerosol comprising nicotine salt particles. Background technique [0002] Devices for delivering nicotine to a user and comprising a source of nicotine and a source of a volatile delivery enhancing compound are known. For example, WO 2008 / 121610 A1 discloses a device in which nicotine and a volatile acid such as pyruvate react with each other in the gas phase to form an aerosol with nicotine salt particles which can be inhaled by the user. [0003] In WO 2008 / 121610 A1 a source of nicotine and a source of a volatile delivery enhancing compound may be housed in a compartment sealed by one or more removable or frangible barriers prior to initial use of the aeroso...
