Embodiment Construction

[0213] figure 1 A schematic illustration of an elongated cartridge 2 for an aerosol generating system for generating an aerosol comprising nicotine lactate particles according to a first embodiment of the invention is shown.

[0214] Cartridge 2 has a length of about 15 mm, a width of about 7 mm and a height of about 5.2 mm. Barrel 2 includes an elongated body 4 , a distal end cap 6 and a proximal end cap 8 .

[0215] The body 4 has a length of about 13 mm, a width of about 7 mm and a height of about 5.2 mm. The distal end cap 6 and the proximal end cap 8 have a length of about 2 mm, a width of about 7 mm and a height of about 5.2 mm.

[0216] Cartridge 2 includes an elongated first compartment 10 extending from a proximal end of body 4 to a distal end of body 4 . The first compartment 10 comprises a nicotine source comprising a first carrier material 12 impregnated with about 10 mg nicotine and about 4 mg menthol.

[0217] Cartridge 2 includes an elongated second compartm...

Abstract

A cartridge (2, 102) for an aerosol generating system, the cartridge comprising a first compartment (10, 110) having a first air inlet (20, 120) and a first air outlet (26, 126) , the first compartment comprises a nicotine source; and a second compartment (14, 114) having a second air inlet (22, 122) and a second air outlet (28, 128), the second compartment comprising Lactic acid source. A ratio of the flow area of ​​the first air inlet to the flow area of ​​the second air inlet is between about 3:4 and about 1:2. An aerosol generating system (200) comprising: the cartridge (102); and an aerosol generating device (202) comprising: a housing defining a cavity (208) for receiving at least a portion of the cartridge ( 206); and a heater for heating said first compartment and said second compartment of said cartridge.

Description

technical field [0001] The present invention relates to a cartridge for an aerosol generating system and an aerosol generating system comprising such a cartridge. In particular, the present invention relates to a cartridge assembly comprising a nicotine source and an acid source for use in an aerosol generating system for in situ generation of an aerosol comprising nicotine salt particles; and a cartridge comprising An aerosol generating system for such cartridges. Background technique [0002] Devices for delivering nicotine to a user are known which include a source of nicotine and a source of a volatile delivery enhancing compound. For example, WO 2008 / 121610 A1 discloses a device in which nicotine and an acid such as pyruvate react with each other in the gas phase to form an aerosol of nicotine salt particles which can be inhaled by a user. [0003] Differences between the vapor concentrations of nicotine and acid in such devices can detrimentally result in poor reacti...
