ABSTRACT:
A device for heating a fragrant gel is assembled from a base plate and a tray holder adapted to hold a gel cartridge. Electrical terminal prongs connect to a heating element which is disposed in an elongated channel in the base plate. The tray holder has a complimentary elongated channel, such that the heating element is completely sealed and electrically insulated when the holder is joined to the plate. The opposite convex side of the channel forms an elongated rail in the holder which acts both as a heat-distribution and a cartridge retaining member.
