1. An aerosol delivery device comprising:
a cartridge comprising an outer housing formed of an outer wall, the outer housing having a mouth end and an opposing connecting end;
an atomizer assembly arranged about the connecting end of the outer housing and comprising:
a base defining a first surface and an opposing second surface, the first surface being engageable with the connecting end of the outer housing to define a reservoir chamber containing an aerosol precursor composition between the outer wall of the outer housing and the first surface of the base,
an atomizer arranged about the first surface of the base to atomize the aerosol precursor composition and form an aerosol,
a liquid transport element arranged about the first surface of the base and defining opposing first and second ends with exposed end surfaces that are in fluid communication with the reservoir chamber so as to direct the aerosol precursor composition from the reservoir chamber through the end surfaces of the liquid transport element and into contact with the atomizer, and
a reservoir chamber sealing arrangement comprising a first sealing member arranged about the first surface of the base and receiving the opposing first and second ends of the liquid transport element 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; and
a control body operably engaged with the cartridge about the connecting end of the outer housing.
