Abstract
A device has a canister for attaching to a fuel container with a wick holder passing through the canister for holding a wick in a position to draw fuel from the reservoir for combustion proximate the top cap. A snuffer in the canister has a sleeve extendible from a first retracted position to a second extended position, the second extended position extending the sleeve partially beyond the wick holder. When the canister is upright the snuffer remains in the first lowered position and when the canister is tilted beyond a predetermined angle the spring moves the sleeve to the second extended position.
