  • Patent number: 5904476
    Abstract: A chafing dish fuel canister is provided having a snuffing device attached thereto. The chafing dish canister has inserted through the lid an inner sleeve which is securely fitted thereon. The wick extends upwards through the inner sleeve from the canister containing the combustible fuel. Over the top of the inner sleeve is place a reservoir sleeve which is press fitted thereon. Reservoir sleeve has an open outwardly extending reservoir formed at the upper portion thereof for retaining excess fuel not burned during use of the chafing dish fuel canister. Surrounding the reservoir sleeve is a snuffing bowl which is movable along the reservoir sleeve. When the canister is overturned, the reservoir bowl snuffs out the flame. The reservoir sleeve has a annular retention recess for preventing the bowl from snuffing the flame unless the dish is actually overturned. Also, the collection reservoir surrounding the wick allows excess fuel to either be burned or drain back into the canister.
