Abstract
The e-vaping cartridge includes a housing, a first tube extending in a longitudinal direction within the housing, the first tube defining at least one first hole that provides fluid communication between a first annulus reservoir and a second annulus reservoir, the first annulus reservoir defined between the housing and the first tube, the second annulus reservoir defined between the first tube and a central passage traversing through the first tube. At least one first layer of absorbent material is positioned within the second annulus reservoir. A wick is in communication with the central passage, where distal ends of the wick contact the at least one first layer of absorbent material. A heater is configured to vaporize a pre-vapor formulation that is communicated by the wick from the at least one first layer of absorbent material. The device includes the cartridge.
