  • Patent number: 6579089
    Abstract: A floating candle holder is provided that includes: an anchor portion formed of a material having a density greater than that of water; a candle having a wick, the candle positioned above the anchor portion; and a shield portion having an opening defined in the top thereof for changing the candle, the shield portion positioned above the anchor portion, about the candle, and extending above the top of the wick of the candle by an amount that is at least 0.7 times as high as the largest horizontal internal dimension of the opening defined in the top of the shield portion. The anchor portion and shield portion are adapted to float the candle on water. The water line of the floating candle holder is within the bottom two-thirds of the overall height of the floating candle holder, and the center of gravity is below the water line, whereby the location of the center of gravity below the water line helps stabilize the floating candle holder against being capsized by winds.
