Electronic nicotine delivery system
First Claim
1. A system for generating a vapor from a liquid comprising:
- a) an electric heater having a body comprising at least one sidewall that defines an interior void, at least one inner surface, at least one outer surface, and a plurality of apertures through the at least one sidewall, the electric heater comprising an electrically resistive material contained within a heat diffusing material;
b) an elongate wick having a longitudinal axis, a first end, a second end, and an outer surface, the elongate wick comprising a durable elongate structure having a plurality of liquid-conducting features on the outer surface;
wherein at least a portion of the liquid-conducting features of the elongate wick proximate the first end engage at least a portion of the at least one inner surface of the electric heater and at least a portion of the liquid-conducting features of the elongate wick are capable of conducting the liquid from a source proximate the second end of the wick along the outer surface of the elongate wick to the electric heater.

Abstract
A system to generate a vapor from a liquid includes an electric heater and an elongate wick. The electric heater defines an interior void having an inner surface and a plurality of apertures, and it is formed of an electrically resistive material contained within a heat diffusing material. The elongate wick is formed of a durable elongate structure having a plurality of liquid-conducting features on the outer surface. At least a portion of the liquid-conducting features of the elongate wick proximate the first end engage at least a portion of the one inner surface of the electric heater and are capable of conducting a the liquid from a source proximate the second end of the wick along the outer surface of the elongate wick to the electric heater.

21. An elongate wick useful in a system for generating a nicotine-containing vapor comprising:
-
a) a solid, elongate structure having a longitudinal axis, a first end and a second end; b) a plurality of longitudinally extending channels defined by longitudinally extending ribs formed on the outer surface of the elongate structure, the channels being arranged and configured to transport a liquid along the elongate wick; and c) an inner bore having a diameter disposed along the longitudinal axis of the elongate structure; wherein the diameter of the inner bore is greater than a distance separating adjacent longitudinally extending ribs. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
