Abstract
A reservoir assembly for a nicotine e-vaping device includes an outer shell, a wick, and a membrane. The outer shell includes a first opening, an inner surface of the outer shell at least partially defining a reservoir configured to hold a nicotine pre-vapor formulation. The wick extends from an interior of the reservoir to an exterior of the reservoir. The wick is configured to draw the nicotine pre-vapor formulation held in the reservoir to the exterior of the reservoir. The first membrane covers the first opening. The first membrane is one or more layers of a fabric that is liquid impermeable and air permeable.
