  Container candleUSPTO Application #: 20060093979Title: Container candle Abstract: The present invention relates to container candles, such as melting plate candles, which employ heat conductive elements to distribute heat from a burning flame at a wick to a support plate for a solid fuel and to the body of said solid fuel, so as to more rapidly liquefy the solid fuel, such as paraffin wax, and to more uniformly and intensely heat such fuels to increase the efficiency of consumption thereof and to more rapidly release volatile materials contained within said fuels. The container of said candle is treated by the application thereto of a thin layer of a low emissivity coating material, such as a doped tin oxide, and the heat conductive support plate is configured so as to have a capillary pedestal upon the surface thereof, which cooperatively engages a wick holder comprising a preferably consumable wick and heat conductive fins which conduct heat from a flame upon said wick to said support plate, said wick holder further engaging said capillary pedestal in such a locking manner as to resist accidental removal from said pedestal. The fuel may be provided in various forms, configured to cooperatively engage said wick holder and support plate, and may comprise various volatile materials. The capillary pedestal, in conjunction with the wick holder, causes rapid and complete flow of the liquefied fuel to said wick. (end of abstract) Agent: S.c.

RELATED APPLICATION(S) [0001] Not applicable. FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable. BACKGROUND OF THE INVENTION [0003] 1. Field of the invention [0004] The present invention relates to a container candle comprising a conventional candle located within a candle holder preferably made of glass. In the preferred embodiments of the invention, the improvement is specifically related to melting plate candles comprising a container, a melting plate, a wick holder, and means to secure the wick clip or wick holder assembly to the melting plate candle, said candle assembly further comprising a replaceable wick and/or fuel puck. This invention is most particularly designed to be used in a melting plate candle having means to provide a capillary feed between the wick holder and the melting plate, as well as in jar candles or conventional container candles. It is to be noted that the primary concept of the present invention, although most effective in a melting plate candle environment, is also useful in any conventional candle utilizing a solid fuel element and a wick upon which fuel is consumed. Although the preferred embodiments of the invention relate to melting plate candles, the invention is broadly applicable to any form of container candle. [0005] 2. Description of the Related Art [0006] Conventional candles are well known, and may constitute such various forms as candle sticks, jar candles, votive lights, tea lights, melting plate candles, and other forms. The present invention relates to those forms of candle in which a solid fuel element is contained within a container, preferably of a glass material so as to permit the passage of light from the flame on the wick to the surrounding area. [0007] Recently, melting plate candles and simmer plate dispensers have been used to provide rapid melting of a solid fuel element and/or rapid dispensing of a vaporizable material to the atmosphere. An example of such a dispensing device is shown in U.S. Pat. No. 6,780,382, issued Aug. 24, 2004, in which a dispenser for active materials is shown. This reference, incorporated herein by reference, illustrates a melting plate dispenser of volatile materials comprising a solid fuel containing active material, a consumable wick, and a heat conductive base having conductive elements, and the configuration of such elements. [0008] In U.S. Pat. No. 6,802,707, issued Oct. 12, 2004, a melting plate candle comprising solid fuel, a consumable wick, a concave melting plate comprising a lobe by which heat is conducted from the flame upon the candle to the plate, and the configuration of such elements, are shown. [0009] In addition to the above, in application Ser. No. 10/780,028, filed Feb. 17, 2004, a candle comprising solid fuel, a melting plate, a lobe which engages a wick holder comprising a wick and conducting heat to said lobe and to said melting plate is taught, wherein said wick holder engages said lobe in such a manner as to create a capillary flow of melted fuel to the wick itself. [0010] In each of the above references, the melting of solid fuel is facilitated by the presence of a melting plate, and by other heat conductive surfaces, such as heat fins which are part of thee wick clip. In addition, the use of conductive lobes is suggested to further distribute heat from the flame to the solid fuel element and to the liquid fuel resulting from melting of the solid fuel. Although these references do teach improved methods for distributing heat to the solid fuel element and to the liquid fuel, it is to be noted that considerable heat is lost by radiation to the surrounding atmosphere, or to the container walls which may comprise materials which are not well suited to conduct heat back to the fuel element or the liquified fuel, but can be heated by the flame to an external surface temperature which is uncomfortable or possibly excessive to the touch. The present invention is directed to a method whereby more of the heat generated by the flame upon the wick may be captured and used to more efficiently melt the fuel element and the pool of liquid fuel, while not heating the container surface to the point that the container surface is unsafe to the consumer. SUMMARY OF THE INVENTION [0011] The present invention relates to a candle holder or container having a reflective or low emission coating applied to the inner surface of the candle holder for the purpose of raising the temperature of the wall so as to assure complete and more rapid melting of the wax adjacent the container wall. By coating of the inner surface of the container, in those areas subject to the radiation of heat from the burning candle, not only is one able to more efficiently heat said surface, but one may, by proper choice of the coating material, assure that the internal surface temperature is elevated sufficiently to assure melt of all wax in contact therewith, while the external surface is not raised to an unsafe temperature. [0012] The present invention, designed for use with a candle holder or dispenser of actives such as a melting plate candle, as described above, but suitable for use with most forms of container candles and/or dispensing devices, may also provide a means for retention of the wick holder at a specific central position, by use of a retention means designed to fit over and around, or within, a specifically positioned pedestal or depression or opening within the bottom of the melting plate. [0013] Specifically, the wick holder of the preferred embodiment of the present invention comprises a wick holder designed to provide heat fins, a wick positioning holder, and a base designed to not only engage a similarly shaped portion of the bottom of the container, in such a manner as to prevent its easy displacement from the bottom of the container, but to also create a capillary flow of melted wax, or liquefied active containing material, between the wick holder itself and the portion of the bottom by which it is engaged. Such an embodiment is shown in U.S. patent application Ser. No. 10/780,028, filed Feb. 17, 2004, incorporated herein by reference. [0014] The present invention thus provides a candle or lamp device capable of rapidly and completely melting a solid fuel to form a large liquid pool, with little or no incomplete melting of wax adjacent the container, thus ensuring efficient and complete utilization of all of the fuel provided, while providing increased safety by limiting the external surface temperature of the container external surface. Further, the concept of the present invention offers highly decorative as well as functional candles and lamps, which may utilize a variety of gel and solid fuels, with the significant advantages of permitting rapid and convenient replacement of one fuel element by another at the desire of the consumer, without the need to clean or scrape the container in which said candle is utilized. [0015] These and other embodiments of the invention shall be illustrated in the figures and description which follow. BRIEF DESCRIPTION OF THE DRAWINGS [0016] FIG. 1 illustrates the basic concept of a melting plate candle of the prior art, in simplified perspective view, of which the present invention constitutes an improvement.
