Abstract
The present invention includes an aerosol delivery device including a cartridge, an atomizer assembly arranged about a connecting end of the cartridge, and a control body operably engaged with the cartridge about the connecting end. The atomizer assembly includes a base defining a first surface engageable with the connecting end to define a reservoir chamber containing an aerosol precursor composition, an atomizer arranged about the first surface of the base, a liquid transport element defining opposing first and second ends with exposed end surfaces that are in fluid communication with the reservoir chamber, and a reservoir chamber sealing arrangement comprising a first sealing member to circumferentially seal the opposing first and second ends of the liquid transport element and expose the end surfaces thereof, such that the reservoir chamber is sealed by the reservoir chamber sealing arrangement except at the exposed end surfaces of the liquid transport element.
