  • Patent number: 7473282
    Abstract: A self-lighting candle includes a body, a wick and a frictionally flammable head proximate the wick. The frictionally flammable head ignites upon being struck against a rough surface. Heat from the flame of the ignited frictionally flammable head lights the wick. The frictionally flammable head may be formed on the wick itself, either proximate or spaced away from the candle body. Alternatively, the frictionally flammable head may be formed on a structurally rigid member partially embedded in the candle body and separate from the wick. A striking surface suitable for striking the frictionally flammable head may be permanently or removably attached to the candle body. For the first lighting of the candle, no match, lighter, or other external source of flame is necessary.
