Abstract
A warmer for scented oil is provided. The warmer includes a base, a cover removably positioned on the base, and a warming device. The cover has a substantially spherical shape with an opening at an upper apex and an open channel formed in the cover at the upper apex around an outer periphery of the opening. The open channel is configured to receive the scented oil. The warming device is in a heat conductive relationship with the cover so that scented oil in the open channel is warmed by the warming device. The warming device can be one or more of a lighting device with an incandescent light bulb, a resistance heater with or without a lighting device such as a light emitting diode, or a candle.
