Abstract
Abstract An end cap for being mounted on a fuel container, which end cap has a projection with a pair of holes through which a wick cord is looped. The free ends of the wick cord are then knotted inside the end cap with the remaining portion of the ends extending into the fuel. The openings in the end cap are larger than the wick cord, thus air is able to pass through these openings along with air passing through openings in the end caps adjacent the projection. This free flow of air shapes the flame to burn upwardly and away from the end cap and in a manner that the cord is not burned. Additionally, it is not possible to pull the cord up above the projection to enlarge the loop to increase the flame height.
