CA 2457064

A flame-retardant wick holder (10, 400) for a candle is made of a material having UL-94 vertical bum test rating of at least V-0, including polymers (i.e. - polyethersulfone, polyphenylsulfone, polyvinylchloride, polysulfones) and ceramics. The wick holder supports a wick (30) at the bottom of a candle (100). 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 (10, 400) includes a barrier (80) extending upwardly around the holder for catching a drooping wick from causing secondary wicking and possible flashover near the end of the candle (100) useful life.

Un support de mèche ignifuge (10, 400) destiné à une bougie est fait d'un matériau correspondant au moins au classement V-0 de combustion verticale selon UL-94, qui comprend des polymères (p.ex. polyéthersulfone, polyphénylsulfone, polyvinylchloride, polysulfones) et des matières céramiques. Le support de mèche sert de support à une mèche (30) dans la partie inférieure d'une bougie (100). Grâce au matériau de support de mèche, la flamme sur la mèche s'éteint dès qu'elle atteint le support, ce qui élimine le risque d'embrasement du combustible restant de la bougie à la fin de la vie utile de la bougie. Dans une variante, le support (10, 400) comprend une barrière (80) qui s'étend verticalement autour du support de manière à pouvoir capter une mèche tombante, à empêcher ainsi la formation d'une mèche secondaire et à éviter le risque d'un embrasement à la fin de la vie utile de la bougie (100).
