DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is now described with respect to various embodiments. It is to be understood that what is described herein need not limit the invention to the specific embodiments described. Those in the field having the benefit of this disclosure will appreciate that the present invention has wide application.
FIG. 1 illustrates a preferred embodiment of the combustible fuel article 10 of the present invention. The combustible fuel article 10 includes a base 12 of vegetable wax and a plurality of cardboard strips 14 extending partially within the wax base 12 and extending outside of the wax base. The wax base 12 binds the cardboard strips 14 together, as shown in FIG. 2.
Although various types of cardboard can be used, recycled cardboard is preferred because of its eco-friendly attributes. The cardboard strips 14 are preferably made from a double-wall or single-wall cardboard that is not waxed or treated in any way. The cardboard should also be kept dry and reasonably clean with no previous exposure to food or oil, such as may be present using recycled cardboard from the restaurant industry.
To form the cardboard strips 14, large pieces of cardboard are cut on a combo cross-cut industrial cardboard shredder. Care should be taken to cut the cardboard with the grain of the cardboard so as to preserve the fluting of the cardboard. This helps maintain the strength and resiliency of the cardboard. The grain of the cardboard can be determined with reference to the ribs or corrugation in the cardboard. Although the specific size of the cardboard strips 12 may vary from application to application, cardboard strips having the dimensions ⅛″×⅛′×4″ have been found suitable for use for most applications. A sufficient length of the cardboard strip 14 should extend beyond the wax base 12 to ensure that the combustible fuel article 10 can be easily lit and the fire sustained until the wax base 12 begins to burn. Having approximately 3.5 inches of the cardboard strip 14 extending beyond the wax base 12 has been found suitable.
Various types of vegetable waxes can be used for the wax base 12. However, pillar and votive soy wax is preferred because of the hardness of the wax. As with the cardboard strips 14, the size of the wax base 12 can vary, depending upon the specific fuel needs of the application. However, a base having a height of approximately 1.5 inches and a diameter of approximately 1 inch has been found suitable for most applications. The preferred embodiment of the combustible fuel article 10 in FIG. 1 is shown with a base 12 formed as a circular cylinder. The base 12 can take on a solid rectangular or other shape as may be preferable for aesthetic purposes.
Following is a description of the preferred method of manufacturing the combustible fuel article 10 in FIG. 1. First, the soy wax is heated until it becomes liquefied. The liquefied wax is then poured into a mold 16 to form the base 12, as shown in FIG. 3. If fragrances, essential oils or other scented oils are used, they are preferably added while the wax is liquefied and before it is poured into the mold 16. A colorant can also be added at the same time.
With the wax still in a liquid state in the mold 16, the cardboard strips 14 are added to the mold 16. The amount and number of cardboard strips 14 used for each mold 16 is relevant to the size and shape of the mold. The cardboard strips 14 should extend outside of the mold 16, above the top surface of the wax base 12. The wax base 12 is then allowed to cool and solidify. Once the wax base 12 has solidified, the combustible fuel article 10 is taken out of the mold 16. The resulting finished product is a combustible fuel article 10 having a solid wax base 12 from which cardboard (preferably shredded) protrudes out of it. Notably, the wax binds the cardboard strips 14 together into a shape and provides a base 12 for the combustible fuel article 10 that sustains the burning process, providing additional fuel and burning at a slower rate than the cardboard strips 14.
To use the combustible fuel article 10 as a fire starter, the user puts the article 10 next to kindling and wood. The combustible fuel article 10 preferably should be leaned against, lying next to or between the wood pieces or fire logs. For best results, the combustible fuel article 10 should be angled approximately 45° to 60° from horizontal with cardboard strips positioned beneath the wax base 12, as illustrated in FIG. 4 where the combustible fuel article 10 is shown with wood pieces 18. This orientation provides a better ignition and a better burning sequence of the combustible fuel article 10. The wood should include small pieces, such as pieces of kindling. The protruding portions of the cardboard strips 14 are ignited with fire by a match or other lighter. The cardboard strips 14 catch on fire and continue to burn. As the cardboard strips 14 burn, they start on fire the remainder of the wood intended to burn. The wax base 12 eventually becomes ignited and actually sustains the fire long enough to allow the neighboring wood to catch on fire.
Those skilled in the art having the benefit of this disclosure will appreciate that the exemplary combustible fuel article 10 described herein provides a natural and earth friendly product, which can make use of renewable vegetable material, such as soybean wax, and recycled cardboard material. No additional harmful chemicals need be added to create the product, and no carbon monoxide or toxic fumes are released into the environment when the combustible fuel article 10 burns.
The combustible fuel article 10 can be used in a dwelling in a fire burning fireplace or wood stove that vents to the outside. It can also be used outdoors in fireplaces, campfires, bonfires, firepits, chimnerias and the like.
The present invention has been disclosed, including its various aspects relating to a new combustible fuel article and methods of manufacturer and use thereof. The present invention contemplates numerous options, variations, and alternatives, and should not be limited to the details of the embodiments set forth herein.
