Abstract: A fully disposable oil candle comprises a disposable blow-molded exterior resin shell made to resemble a conventional beeswax candle and an inner disposable fuel cell. By configuring the fuel cell to include a separating structure to fit within a radial groove inside the opening of the shell, the cell and the exterior shell can be permanently joined, forming a candle that closely resembles an ordinary beeswax candle. Moreover, the separating structure of the fuel cell acts to provide distance between the fuel cell and the exterior shell, partially insulating the exterior shell from the heat of the fuel cell. By maintaining an insulating distance between the fuel cell and the exterior shell, the exterior shell can be made less robust. The result is a candle that is less expensive to manufacture and ship and more convenient for consumers to use. In addition, the separating structure can act as a safety feature by making it more difficult for individuals to remove the fuel cell from the candle once assembled.
