Abstract:
The method of making the e-vaping cartridge includes cutting at least one first hole through a first channel, sliding a housing over the first channel, the at least one first hole providing fluid communication between a first reservoir and a second reservoir, the first reservoir being defined between the housing and the first channel, where the second reservoir is defined between the first channel and a central passage traversing through the first channel. The method further includes inserting at least one first layer of absorbent material within the second reservoir, and positioning a heater and a wick in communication with the central passage. Distal ends of the wick contact the at least one first layer of absorbent material, where the 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.
