Abstract:
A cartridge for an e-vaping device enables separate vapors to be formed proximate to separate, respective ends of the cartridge. The cartridge includes multiple reservoirs and separate vaporizer assemblies coupled to separate reservoirs on opposite ends of the reservoirs. The separate reservoirs may hold separate pre-vapor formulations. The separate vaporizer assemblies may draw separate pre-vapor formulations from separate reservoirs towards opposite ends of the cartridge and vaporize the separate pre-vapor formulations via operation of separate heaters proximate to the separate ends. The separate heaters may be independently controlled to independently control vapor formation at the separate ends. The heaters may be controlled to independently control vapor formation rates proximate to the separate ends. The heaters may be controlled to form separate vapors at least one of simultaneously, concurrently, and at different times.
