Abstract
A reservoir assembly for a non-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 non-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 non-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.
Claims22
A reservoir assembly for a non-nicotine e-vaping device, the reservoir assembly comprising:
- an outer shell including a first opening, an inner surface of the outer shell at least partially defining a reservoir configured to hold a non-nicotine pre-vapor formulation, the non-nicotine pre-vapor formulation being devoid of nicotine and including at least one non-nicotine compound;
- a wick extending from an interior of the reservoir to an exterior of the reservoir, the wick configured to draw the non-nicotine pre-vapor formulation held in the reservoir to the exterior of the reservoir;
- and
- a first membrane covering the first opening, the first membrane including
- one or more layers of a fabric that is liquid impermeable and air permeable.
A reservoir assembly for a non-nicotine e-vaping device, the reservoir assembly comprising:
- an outer shell extending in a first direction, the outer shell including a first end and an inner surface, the inner surface of the outer shell defining an interior of the outer shell;
- a plunger extending through the interior of the outer shell in a second direction normal to the first direction, the plunger including a first surface and a second surface opposite the first surface, a portion of the inner surface of the outer shell defining a liquid containment area in a portion of the interior of the outer shell between the first surface of the plunger and the first end of the outer shell, the liquid containment area being a reservoir configured to hold non-nicotine pre-vapor formulation, the plunger configured to move in the first direction within the interior of the outer shell in response to a first force being applied to the first surface of the plunger by a volume of the non-nicotine pre-vapor formulation contained in the liquid containment area, the non-nicotine pre-vapor formulation being devoid of nicotine and including at least one non-nicotine compound;
- and
- a wick extending from the interior of the outer shell to an exterior of the liquid containment area.
A method of filling a non-nicotine e-vaping device, comprising:
- providing an outer shell and a plunger, the outer shell extending in a first direction, the outer shell including a first end, an opening in the first end, and an inner surface, the inner surface of the outer shell partially defining an interior of the outer shell, the plunger extending through the interior of the outer shell in a second direction normal to the first direction, the plunger including a first surface and a second surface opposite the first surface, the first surface and a limited portion of the inner surface of the outer shell define a liquid containment area in the limited portion of the interior of the outer shell between the first surface of the plunger and the first end of the outer shell, the liquid containment area being a reservoir configured to hold non-nicotine pre-vapor formulation, the non-nicotine pre-vapor formulation being devoid of nicotine and including at least one non-nicotine compound;
- filling the liquid containment area with the non-nicotine pre-vapor formulation such that the plunger is moved in the first direction away from the first end of the outer shell by the non-nicotine pre-vapor formulation, based on the non-nicotine pre-vapor formulation applying a first force on the first surface of the plunger;
- and
- placing a portion of a wick into the liquid containment area.
