  • Publication number: 20260198544
    Abstract: A cartridge may include a housing, a liquid supply reservoir in the housing and configured to store a pre-vapor formulation, a vaporizer, and a porous plug. The vaporizer may be in liquid communication with the liquid supply reservoir. The vaporizer may be configured to generate a vapor from heating a portion of the pre-vapor formulation. The porous plug may be connected to the housing and separated from the liquid supply reservoir. The porous plug may be permeable to the vapor. The porous plug may enclose a flavoring additive contacting a storage material. The flavoring additive may be configured to at least partially elute from the storage material or at least partially volatilize from the storage material if the vapor flows through the porous plug. An e-vaping device may include the cartridge.
