  • Publication number: 20060024629
    Abstract: Provided is a liquid fuel candle comprising a wax body with a hollowed core, a base defining a reservoir for storage of liquid fuel attached to one end of the wax body, an insulator attached to the other end of the wax body, and a wick threaded through the hollowed core and communicating at one end with the liquid fuel and at the other end with the insulator. The base may be formed and dimensioned to resemble a conventional candle holder, and since the liquid fuel is stored within the reservoir provided by the base, the wax body may be very slender and thin without compromising candle burn time. A diffuser ring may be associated with the insulator for evaporation and dispersion of scented oils. More than one wax body, wick and insulator may be associated with a single base.

  • Patent number: 6638060
    Abstract: An everlasting candle comprising a wax body with a recessed hollow in its top for receiving an insulating container, and a smaller holding container with an annular rim set within the insulating container and communicating with the insulating container only by the rim (thereby to provide an insulative airspace between the two containers), the holding container being suitably dimensioned to replaceably receive a tea light votive candle. In use, the replaceable tea light votive candle within the everlasting candle burns with the same flame as a conventional paraffin candle, and will be liquefied and consumed during use. However, since the main wax body of the everlasting candle is separate and insulated from the replaceable tea light votive candle, the wax body of the everlasting candle will not be liquefied or consumed.
