Abstract:
A candle comprising:a body of fuel having a top region and base a region thereof; an absorbent wick supported within the body of fuel and having a top and a base region corresponding to the top region and the base region of the body of fuel, whereby in use the top region of the body of fuel falls as the fuel is consumed and a top portion of the wick projects from the top region of the body of fuel to serve as a combustion station at which fuel conveyed by the wick from the body of fuel is combusted to create a flame; and a spacing member comprising a first portion which substantially encircles the wick at a location within the body of fuel above the base regions of the wick and the body of fuel to define a lower limit of travel of the combustion station as the body of fuel is consumed and a second portion which extends below the first portion whereby the said lower limit of travel of the combustion station is spaced above the base region of the body of fuel; wherein: (a) the spacing member comprises a sleeve having first and second ends and a sleeve body between the two ends, the first end defining the first portion of the spacing member; (b) the sleeve engages at its second end a sustainer disposed at the base of the body of fuel which anchors the base region of the wick, whereby the sleeve body defines the second portion of the spacing member, substantially encircles the wick and extends to the sustainer at the base of the body of fuel; (c) the thermal conductivities of the spacing member and the sustainer are such that fuel at the base region of the body of fuel is melted by the heat of the flame burning at the lower limit of travel of the combustion station; and (d) the spacing member and sustainer are arranged so that molten fuel can contact the base region of the wick while the spacing member remains in position during low burning of the base region of the body of fuel.
