ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATIONS
Not Applicable.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
Not Applicable.
BACKGROUND
1. Field of Invention
This invention relates to liquid-fuel imitation candles, specifically to safe, efficient, cool-burning methods of supplying fuel to a decorative flame.
2. Description of Prior Art
Places of worship have long used candles as decoration, as symbols of departed souls, and as devices to solicit donations. More recently, oil-fired lamps have been used for the same purposes. Liquid fuels have been developed to burn cleanly, without noticeable odor, and without the wax residue characteristic of spent candles. Problems inherent in liquid-fueled imitation candles include heat build-up in the wick holder, and management of the return flow of fuel. Re-fueling processes, while straightforward, admit to fluid spills and resultant oily residues, as well as possible fire hazards.
SUMMARY
A specially-shaped wick holder, in conjunction with an irregularly-shaped refueling orifice, is capable of efficient heat dissipation and fluid return.
OBJECTS AND ADVANTAGES
The objects and advantages of the present invention are:
(a) To provide a liquid-cooled wick holder, which prevents heat damage to composition parts.
(b) To provide a fluid return path to compensate for capillary action in excess of that required to support a flame.
(c) To provide an easily refilled body and wick holder assembly.
