The present invention includes a wick holder (20), whereby the upper portion of the ferrule is "S" crimped (30), without piercing the ferrule (24), to reduce the flow of fuel upward through the ferrule. The bottom of the base (22), on the opposite side of the cylindrical ferrule, is completely sealed off by a hot-melt adhesive (42), thereby preventing fuel from traveling up the hollow ferrule (24). By reducing the flow of fuel within the present wick holder, the wick holder restricts the supply of fuel to the candle wick when the flame burns the candle wick down to the top of the wick holder ferrule. By restricting the supply of fuel to the wick, the candle flame, upon burning down to the top of the wick holder, self-extinguishes before allowing the flame to approach the surface of the glass candle holder (15).
L'invention concerne un porte-mèche de chandelle (20) dans lequel la partie supérieure de la virole est sertie en "S" (30), sans percement de la virole (24), de manière à réduire l'écoulement de combustible vers le haut, via la virole. Le fond de la base (22), sur le côté opposé de la virole cylindrique, est entièrement colmaté par un adhésif thermofusible (42), ce qui empêche le combustible de remonter par la virole creuse (24). En réduisant le flux de combustible dans le porte-mèche considéré, on parvient à limiter l'apport de combustible à la mèche de la chandelle lorsque la flamme brûle la mèche jusqu'au sommet de la virole du porte-mèche, moyennant quoi la flamme s'éteint d'elle-même avant d'atteindre la surface du bougeoir en verre (15).
