Embodiment Construction

[0015] The following description is of exemplary embodiments only and is not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0016] The present invention is directed to a wick that is capable of self-extinguishing or otherwise self-obstructing combustion. In this manner, the wick is configured such that combustion along the wick changes from a first combustion rate to a second combustion rate. In a preferred embodiment, the second combustion rate becomes essentially zero such that the wick self-extinguishes. In another embodiment of the invention, the second combustion rate is slower than the first combustion rate such th...

Abstract

A wick includes a first wick portion and a second wick portion. At least one combustion barrier is positioned between the first and second wick portions. The combustion barrier is configured to obstruct combustion from the first wick portion to the second wick portion.

Description

[0001] The present invention relates generally to wicks, and more particularly to a self-extinguishing candle wick and a method of producing the same.[0002] Candle wicks are generally made of a plurality of ignitable fibers that are braided or otherwise woven together. The wicks sustain combustion, thereby maintaining a flame at an end of the wick, by transporting a liquid fuel, such as melted wax, along the fibers by capillary action. The fibers may be made of cotton, spun fiberglass, synthetic fiber or similar material that is capable of absorbing the liquid fuel. The wicks may also include a core of material, such as metal, paper, cotton or the like, that adds to the wicks rigidity.[0003] Candle combustion typically is known to depend on three components that comprise the "fire triangle." These components include fuel, heat and oxygen (or air), and appropriate proportions of any of these components are important to support candle combustion. When an external flame is brought to t...
