Abstract:

A candle assembly includes a support base, a melting plate having a capillary pedestal, a wick holder that fits onto the capillary pedestal, and a fuel element that fits over the wick holder. The wick holder includes a sleeve having first and second open ends. A wick fits into the sleeve and extends between the open ends. The sleeve has a constricted portion, which is disposed between the open ends and has a cross-sectional area less than any other cross-sectional area between the open ends. The constricted portion reduces an effective capillary fluid flow capacity of the wick between the open ends, which may thereby regulate how quickly fuel is consumed when the candle assembly is burning. A capillary well disposed between the wick holder and the capillary pedestal may be adapted to promote a successful relight after an initial burn of the candle assembly. A candle holder, such as including the melting plate supported by a base, may be adapted to promote laminar air flow thereacross during a burn in a substantially calm atmospheric environment.
