     BACKGROUND OF INVENTION 
     1. Field of the Invention 
     This invention relates to devices for releasing a scent or fragrance from a scented candle. More specifically, this invention relates to devices for releasing a scent or fragrance from a scented candle that employs an electric heating element to warm or melt the scented candle. 
     2. Description of the Related Art 
     A variety of devices and techniques are well known for heating a scented candle. As candles typically have a wick, it is known to light the wick to heat the scented candle. The disadvantage of this technique is that as the wick is burned the candle is used up. It is also known to place the candle, in its container, on an electric heater or warmer. The disadvantage of this approach is that the wax or gel is heated from the bottom and that the scent is not generally released until the top surface is liquefied. A number of other devices that use heat to enhance the release of a scent are known and described in the following U.S. patent documents, which although not necessarily meeting the statutory requirements of prior art are each hereby incorporated by references in its entirety for the material contained therein: U.S. Pat. Nos. 4,137,833, 4,346,059, 4,595,564, 4,634,838, 5,651,942, 6,254,836, 6,516,142, 6,539,171, and 6,548,015.

     DETAILED DESCRIPTION 
     The invention is a heater device for heating a scented candle to enhance the deployment of the aroma from the candle. Scented candles have been developed to release a desirable aroma from the candle as it is heated. Typically, the scented candles are provided with a wick, although heating the candle by burning the wick has substantial disadvantages, including that the candle becomes used up over time and that the release of the aroma is uneven. The scented candles are generally contained within a glass jar or other similar heat conducting material. This invention provides heat to the candle by wrapping a conductor about the exterior of the candle container. The conductor is attached to an AC plug, which when plugged into a standard AC outlet, provides a current through the conductor, causing the conductor to heat up. The heated conductor heats the candle container, thereby heating the candle material, typically wax or gel, which when melted releases an aroma from the candle. The present embodiment of the invention includes a heat and electricity insulating cover located about the area of the conductor not intended to be in contact with the candle container. In some embodiments, a fuse is provided in series with the conductor to provide electrical safety measures. 
     Referring now to  FIG. 1 , which is a side view of the present embodiment of the invention  100  wrapped about a candle container. The candle  101  is held within a container  102 . The present candle  101  is an aromatic candle composed of wax, gel or the like. The container  102  is presently a glass jar, glass, cup, bowl or the like. The materials of the container  102  should be relatively resistant to heat deformation while being a good conductor of heat; therefore certain metals and ceramics may be substituted for glass as the container material. The typical candle  101  generally includes a wick  103 , although the presence of a wick is not required for use with this invention. The conductor assembly  104  is shown wrapped about the exterior of a side wall  111  the candle container  102 . Although shown here wrapping around the container  102  four times, the number of times that the conductor assembly  104  goes around the container  102  depends on the length of the conductor assembly  104  and the circumference of the container  102 . In some instances the conductor assembly  104  may circle the container  102  many times and in other instances the conductor assembly  104  may not extend complete around the container  102  even once. The conductor assembly  104  is connected at a first end  109  to a first electrical conductor  106  and is connected at a second end  110  to a second electrical conductor  107 . The first  106  and second  107  electrical conductors a formed together into an electrical cord  105 , which in turn is connected to a standard electrical plug  108  adapted for insertion into a standard wall outlet. 
       FIG. 2  shows the aromatic container heater of this invention with additional detail of the conductor assembly  104 , specifically the conductor  201  and the insulating cover  202 . In the present embodiment of the invention the conductor  201  is a bendable copper tube, although in alternative envisioned embodiments, the bendable copper tube can be substituted with a stranded cable, a mesh, a chain or another bendable but moderately rigid metal devices. Also, the material used in the conductor  201  can be substituted with another other electrical/heat conducting material, including, but not necessarily limited to, aluminum, tin, silver and gold. The first end  109  of the conductor assembly  104  is shown with the first electrical conductor  106  electrically connected to the conductor  201  and the second end  110  of the conductor assembly  104  is shown with the second electrical conductor  107  electrically connected to the other end of the conductor  201 . The insulating cover  202  is adapted to cover the portion of the conductor  201  that is not intended to be in contact with the candle container  102 . A portion  203  of the conductor  201  remains exposed for direct contact with the candle container  102 . The present preferred insulating cover  202  is composed of plastic, although other electrical and heat insulating materials, including rubber, cloth, paper, wound glass, mica and the like can be substituted without departing from the concept of this invention. 
       FIG. 3  shows the embodiment of the invention that includes an in-line fuse  301  electrically connected between the plug  300  and the electrical cord  105  to provide an electrical safety feature to the invention and an ON/OFF switch  302  also in-line between the plug  300  and the heat conductor  201 . 
     It is to be understood that the above described and referenced embodiments and examples are merely illustrative of numerous and varied other embodiments and applications which may constitute applications of the principles of this invention. These example embodiments are not intended to be exhaustive or to limit the invention to the precise form, connection or choice of components or materials disclosed herein as the present preferred embodiments. Obvious modifications or variations are possible and foreseeable in light of the above teachings. These embodiments of the invention were chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to make and use the invention, without undue experimentation. Other embodiments may be readily devised by those skilled in the art without departing from the spirit or scope of this invention and it is the intent of the inventor that they be deemed to be within the scope of this invention, as determined by the appended claims when they are interpreted in accordance with the breadth to which they are fairly legally and equitably entitled.
