Abstract
A candle has a core of solid fuel that can be burned by a flame on a wick in the fuel. A flame resistant and heat resistant polyethersulfone (“PES”) barrier is around the core, the PES barrier being at least partly transparent for passing light from the flame. A clear, rigid, outer shell of shell material around the PES barrier allows light from the flame to pull to an outer surface of the shell. An opaque pattern is on the PES barrier for projecting an image of the pattern with light from the flame and a translucent wrap at the outer surface of the shell receives the projected image of the pattern. Alternatively, decorative items are in the shell which are visible through the transparent material of the shell and are protected from the heat of the flame by the PES barrier.
Claims45
A candle comprising:
- a core of solid fuel that can be burned by a flame on a wick in the fuel;
- a wick extending in the core for burning the fuel;
- a flame resistant and heat resistant polyethersulfone barrier around the core, the polyethersulfone barrier being at least partly transparent for passing light from a flame burning the fuel on the wick;
- and
- a clear, rigid, outer shell around the barrier for passing light from the flame to an outer surface of the shell.
A candle comprising:
- a core of solid fuel that can be burned by a flame on a wick in the fuel;
- a wick extending in the core for burning the fuel;
- a flame resistant and intumescent barrier around the core having a melting point higher than heat temperature generated by the flame, a softening point as low as 20 degrees below the melting point but higher than the heat temperature generated by the flame, and a UL94 flammability rating of at least V-0, wherein the barrier is at least partly transparent for passing light from a flame burning the fuel on the wick;
- and
- a clear, rigid, outer shell around the barrier for passing light from the flame to an outer surface of the shell.
