Abstract
Candles are provided for dispensing air treatment chemicals in response to heat. There is a lid bearing the air treatment chemical. The candle includes a housing with a combustible fuel. An upper lid includes a cover plate bearing the air treatment chemical and an opening centrally disposed in the plate to allow heated air to pass through when the fuel is being combusted. The plate is suspended across an upper end of a side wall of the housing creating an air gap adjacent the radial periphery of the lid. When the fuel is combusted the air treatment chemical can be heated thereby and carried away by heated air that has passed through the central opening, and the air gap can permit cooler air to enter the cavity while the fuel is being combusted.
