Abstract
A cartridge for selective delivery of aerosol precursor compositions includes a housing, and a reservoir disposed within the housing and defining three chambers each having an aerosol precursor composition therein. The reservoir is in fluid communication with an aerosol forming arrangement configured to form an aerosol from any of the aerosol precursor compositions. A selector defines one or more dispensing selectively aligned with one or more of the three chambers, such that the aerosol precursor composition disposed within each of the three chambers is capable of being dispensed therefrom through the selectively aligned dispensing ports to the aerosol forming arrangement. The cartridge further includes a flow tube extending longitudinally through a central axis of the reservoir and the selector so that each of the three chambers is arranged circumferentially around the flow tube, the flow tube being disposed so that the formed aerosol is transported through the flow tube.
