The plug 17 is placed in the hole, and the lamp lighted. As the liquid evapcrates its vapors issue through vent holes 953. When desired the device may he placed on a fiat surface, such as the top of a stove, radiator or cave bottom provided with a plurality of semiresilient retaining fingers depending therefrom normally curved to conform to the surface of an 7 electric lamp globe and having feet at their lower ends, a g hole in the top of said vessel, and a removable plug therefor, a plurality of vent holes spaced around the upper rim of said vessel, and fibrous absorbent material filling the interior thereof; said vessel being'composed of an upper part and a lower part; said upper part being cup shaped and joined in inverted position to said lower part, and said lower part having its central portion formed and shaped to provide a concave bottom closure for said upper part together with integral strips depending from said central portion to said retaining m gers, said upper and lower part being joined in fluid tight relation.
