Abstract

A self-extinguishing candle and method of making the candle are described. The self-extinguishing candle comprises a candle body formed of a candle base material and a flame resistant block in contact with or attached to the candle body. The flame resistant block is capable of extinguishing the candle flame after the candle body is substantially consumed by the candle flame. The flame resistant block is formed of at least one flame resistant.

Claims

         16 . The candle of  claim 15 , wherein the gelling agent is a di-block copolymer, tri-block copolymer, radial copolymer, star polymer, multi-block copolymer, or a mixture thereof.  
     
     
         17 . The candle of  claim 1 , wherein the first portion of the candle further includes a hydrocarbon oil in the candle base material.  
     
     
         18 . The candle of  claim 1 , wherein the first portion of the candle further includes an additive in the candle base material.  
     
     
         19 . The candle of  claim 18 , wherein the additive is an antioxidant, stabilizer, fragrance, colorant, insect repellant, or a mixture thereof.  
     
     
         20 . The candle of  claim 1 , wherein the first portion of the candle further includes an object.  
     
     
         21 . The candle of  claim 20 , wherein the object is an insoluble star, glitter, sparkle, ribbon, or a combination thereof.  
     
     
         22 . The candle of  claim 1 , wherein the candle is free-standing.  
     
     
         23 . The candle of  claim 1 , wherein the candle is contained in a jar.  
     
     
         24 . A self-extinguishing candle, comprising: 
 a candle body formed of a paraffin wax; the candle body being opaque or substantially opaque,    a wick inside the candle body for sustaining a candle flame when lit, and    a flame-resistant block in contact with one end of the candle body, the flame-resistant block including at least one flame retardant and being capable of extinguishing the candle flame after the candle body is substantially consumed by the candle flame.    
     
     
         25 . A method of making a self-extinguishing candle comprising: 
 forming a candle body from a candle base material;    forming a flame-resistant block from at least one flame retardant; and    joining the flame-resistant block to the candle body.
