Flame-resistant wick holder for candle
View Patent ↗A flame-retardant wick holder for a candle is made of a material having a UL-94 vertical burn test rating of at least V-0, including polymers and ceramics. The wick holder supports a wick at the bottom of a candle. The wick holder material causes the flame on the wick to extinguish when it reaches the holder, thereby preventing flashover of the residual candle fuel at the end of the candle useful life. One version of the holder has a cylindrical sleeve fit over a wick clip holding the lower end of the wick. The cylindrical holder is well adapted for use in pillar-type candles.
1. A wick assembly for a candle having a wick, the candle made from a fuel capable of melting to form a liquid pool and traveling by capillary action to a flame burning on the wick, the wick assembly comprising:
a wick clip holding one end of the wick inside a tube having an upper end, the wick extending from the upper end;
a sleeve having a top end, a bottom end, a side wall connecting the top end to the bottom end, and a bore through the sleeve for fitting around the tube and the wick, the sleeve top end positioned adjacent or extending past the tube upper end, the sleeve being made from a non-combustible material selected from the group consisting of polyethersulfone and polyvinylchloride.
2. A wick assembly according to claim 1 , wherein the sleeve is frictional fit to the tube.
3. A wick assembly according to claim 1 , wherein the sleeve is cylindrical.
4. A wick assembly according to claim 3 , wherein the sleeve diameter is about 0.25 inches.
5. A wick assembly according to claim 4 , wherein the wick clip further comprises a disc shaped portion connected to the tube adjacent the one end of the wick.
6. A wick assembly according to claim 1 , wherein the sleeve is fixed to the wick clip by an adhesive.
7. A wick assembly according to claim 1 , wherein the top end of the sleeve extends past the tube upper end.
8. A wick assembly according to claim 7 , wherein the top end extends past the tube upper end at least 0.125 inches.
9. A self-extinguishing candle, comprising:
a wick clip holding one end of a wick inside a tube having an upper end, the wick extending from the upper end;
a sleeve having a top end, a bottom end, a side wall connecting the top end to the bottom end, and a bore through the sleeve for fitting around the tube and the wick, the sleeve top end positioned adjacent or extending past the tube upper end, the sleeve being made from a non-combustible material selected from the group consisting of polyethersulfone and polyvinylchloride;
a candle fuel surrounding the sleeve, the wick extending through the candle fuel so that at least a portion of the wick is exposed above the candle fuel for lighting to melt the candle fuel adjacent the wick, the sleeve extinguishing a flame burning on the wick when the flame reaches the top surface of the sleeve.
10. A self-extinguishing candle according to claim 9 , wherein the sleeve is frictional fit to the tube.
11. A self-extinguishing candle according to claim 9 , wherein the sleeve is cylindrical.
12. A self-extinguishing candle according to claim 11 , wherein the sleeve diameter is about 0.25 inches.
13. A self-extinguishing candle according to claim 12 , wherein the wick clip further comprises a disc shaped portion connected to the tube adjacent the one end of the wick.
14. A self-extinguishing candle according to claim 11 , wherein the candle fuel forms a pillar candle.
15. A wick assembly according to claim 9 , wherein the sleeve is fixed to the wick clip by an adhesive.
16. A wick assembly according to claim 9 , wherein the top end of the sleeve extends past the tube upper end.
17. A wick assembly according to claim 16 , wherein the top end extends past the tube upper end at least 0.125 inches.
