Abstract
Abstract An oil lamp includes beverage can of the tab opening type having a sector shaped discharge opening and defining an oil reservoir. A resilient wire helix wick holder engages the upper portion of a wick and engages between successive convolutions the opposite convergent edges of the discharge opening, the wick being immersed in the oil in the can and projecting a short distance above the helix. Alternatively, the wick holder is a pair of telescoping collars having opposing flanges embracing the inner opposite borders of the discharge opening and engaging the wick.
