Candle and method of making same

Abstract

A candle including regions made up of fuels which produce differing flame heights and/or flame levels when burned, and a method of making such a candle, are disclosed.

1 . A candle, comprising: 
 a candle body comprising first and second regions, the first region formed of a first fuel producing a first flame height when burned, and the second region formed of a second fuel, different from the first fuel, producing a second, larger flame height when burned, wherein the first region is disposed over the second region; and    a wick disposed in the candle passing through the first and second regions, a portion of the wick protruding from the first region,    wherein the candle, when lit, provides an overall flame level lower, with respect to the base of the candle, than the flame level which would result from the same candle without the first region.    
   
   
       2 . The candle of  claim 1 , further comprising a non-flammable, open-ended container, wherein the candle is disposed inside the container with the protruding portion of the wick exposed.  
   
   
       3 . The candle of  claim 2 , wherein the candle, in lit use, will not ignite a single layer of tissue paper placed on the top of the container within ten seconds.  
   
   
       4 . The candle of  claim 3 , wherein the second region is such that an identical candle, omitting the first region, in lit use ignites a single layer of tissue paper placed on the top of the container within ten seconds.  
   
   
       5 . A candle according to  claim 1 , wherein the first region comprises less than 10% of the candle, based on the total weight of the fuel.  
   
   
       6 . A candle according  claim 1 , wherein the first region has a smaller average cross-sectional area than the second region.  
   
   
       7 . A candle according  claim 1 , wherein at least one of the fuels is non-liquid.  
   
   
       8 . A candle according to  claim 7 , wherein at least one of the fuels comprises a wax.  
   
   
       9 . A candle according to  claim 7 , wherein the first fuel is non-liquid and comprises vegetable oil triglycerides.  
   
   
       10 . A candle according to  claim 9 , wherein the first fuel comprises palm oil triglycerides.  
   
   
       11 . A candle according to  claim 9 , wherein the second fuel is non-liquid and comprises an aliphatic hydrocarbon.  
   
   
       12 . A candle according to  claim 11 , wherein the second fuel comprises an alkane.  
   
   
       13 . A candle according to  claim 12 , wherein the second fuel comprises a semi-refined paraffin.  
   
   
       14 . A candle, comprising: 
 a candle body comprising first, second, and third regions formed of corresponding first, second, and third fuels, the first region disposed over the second region and the second region disposed over the third region, wherein the fuel forming the second region produces a flame height, when burned, different from the flame height produced by the fuel forming the first region and different from the flame height produced by the fuel forming the third region; and    a wick disposed in the candle passing through the first, second, and third regions, a portion of the wick protruding from the first region.    
   
   
       15 . A candle according to  claim 14 , wherein at least one of the fuel regions is non-liquid.  
   
   
       16 . A candle according to  claim 15 , wherein each of the first, second, and third fuel regions is solid.  
   
   
       17 . A candle according to  claim 16 , wherein the second region has a smaller average cross-sectional area than the third region and wherein the fuel forming the second region produces a flame height smaller than the fuel forming the third region.  
   
   
       18 . A candle according  claim 17 , wherein the first region has a larger average cross-sectional area than the second region and wherein the fuel forming the first region produces a flame height larger than the fuel forming the second region.  
   
   
       19 . A candle according  claim 17 , wherein the first region has a smaller average cross-sectional area than the second region and wherein the fuel forming the first region produces a flame height smaller than the fuel forming the second region.  
   
   
       20 . A candle according  claim 16 , wherein the fuel forming the second region produces a flame height larger than the fuel forming the first region and larger than the fuel forming the third region.  
   
   
       21 . A candle according to  claim 14 , comprising a plurality of regions comprising respective fuels, wherein the wick passes through each of the regions, and wherein the size of the flame height produced by each of the fuel regions is in relative proportion to the average cross-sectional area of each of the regions.  
   
   
       22 . A candle according to  claim 14 , wherein at least one of the differences in flame height is at least 20% of the flame height produced by produced by the fuel forming the second region.  
   
   
       23 . A candle according to  claim 22 , wherein the difference in flame height is at least 33% of the flame height produced by produced by the fuel forming the second region.  
   
   
       24 . A candle according to  claim 23 , wherein the difference in flame height is at least 100% of the flame height produced by produced by the fuel forming the second region.  
   
   
       25 . A method of making a candle, comprising the steps of: 
 providing a body of first solid wax fuel disposed in a non-flammable container and having a wick disposed therein, a portion of the wick exposed at a top end of the body and the container;    forming a layer of second solid wax fuel over the top end of the body; and    selecting the second solid wax fuel to provide a flame height shorter than the flame height provided by the first solid wax fuel when burned under identical conditions.    
   
   
       26 . The method of  claim 25 , further comprising selecting the first solid wax fuel and providing the body of first solid wax fuel such that the body of first solid wax fuel would, in lit use in the container, ignite a single layer of tissue paper placed on the top of the container within ten seconds.
