OG exemplary drawing
 
1. A cartridge for an e-vaping device, the cartridge comprising:
a first reservoir configured to hold a first pre-vapor formulation;
a second reservoir configured to hold a second pre-vapor formulation
a channel structure including,
a channel surface, the channel surface including,
a first channel surface portion defining at least one inner surface of the first reservoir, the second reservoir, or both the first reservoir and the second reservoir, and
a second channel surface portion adjacent the first channel surface portion, the channel surface configured to draw the first pre-vapor formulation from the first reservoir and to draw the second pre-vapor formulation from the second reservoir, the channel structure being a disc structure, the first channel surface portion being an outer annular portion of the channel surface, and the second channel surface portion being an inner portion of the channel surface, and
a plurality of open-microchannels extending between the first channel surface portion and the second channel surface portion, each of the plurality of open-microchannels being in fluid communication the first reservoir or the second reservoir; and
at least one heating element configured to vaporize the first pre-vapor formulation, the second pre-vapor formulation, or both the first pre-vapor formulation and the second pre-vapor formulation.
