Definitions

• the subject matter relates generally to a heat source and a method of using the heat source that controls a prolonged and continuous burning of charcoal without the use of a lighting fluid or other igniting aid.
• the main problems with lighting fluids or other similar aids include the likelihood that the lighting fluid or at least fumes from the lighting fluid will penetrate into the cooking food. Also, lighting fluid is itself an environmental pollutant, releasing volatile organic compounds (VOCs) into the atmosphere. Still another frustrating aspect of lighting fluid is the user generally must be carrying the lighting fluid as a separate, dangerously combustible item.
• VOCs volatile organic compounds
• Another method ignition uses an electric charcoal starter. A layer of charcoal is laid down, then the electric starter is placed on top and then an additional layer of charcoal is placed over the top of the starter. The electric charcoal starter is then plugged in and ignites the charcoal once it has heated up sufficiently. This process is also time consuming and has the restriction of requiring access to an electrical outlet. Just as the chimney starter, the electric charcoal starter must be allowed to cool before it can be safely stored. This method is most obviously limited by the necessity of an electrical outlet, which is not always available when barbequing, as well as the required cooling period. [0012] While these two methods forego the use of lighter fluid, they still have limitations suggesting that a disposable, portable ignition source would be more convenient and safer for the ignition of charcoal.

• An inner chimney flue receives air for igniting and burning the charcoal-based fuel and an outer chimney flue exhausts the combustion fumes from the charcoal-based fuel.
• a bottom wall member secures to the inner chimney to flue and the outer chimney flue and forms a combustible material to be consumed during the ignition of the charcoal-based fuel.
• the top of the device is left open to exhaust the combustion fumes from the outer chimney flue.
• An ignition ring establishes a sustained ignition of sufficient duration to ignite uniformly the charcoal- based fuel.
• the inner chimney flue, outer chimney flue, the open top, the ignition lattice, and the inner chimney insert cooperate to provide uniform and rapid burning of the charcoal-based fuel.
• This disclosure provides a long-burning charcoal-based heat source that requires no lighting fluid or similar igniting aid for either initial or sustained burning.
• This package is designed such that it may be folded flat to facilitate ease of transportation and assembly of final product.
• Yet a further object of the present disclosure is to provide a combustible package that includes a self-contained igniter for eliminating any need for petroleum-based flame accelerators.
• an ignition ring also of a non-polluting combustible material, maintains a flame that assures the charcoal will light during the burning of the combustion package.
• the inner chimney flue insert also made of a non-polluting combustible material, may be placed under the package in circumstances where the barbeque grill or smoker does not allow sufficient airflow to the inner chimney flue. Additionally, the opening at top of the package forms a secondary exhaust chimney, resulting in a conductive path for the hot exhaust fumes generated by the igniting charcoal. This causes a more rapid and more reliable burning of the charcoal.
• Still another object of the present disclosure is the provision of a charcoal package in which charcoal will be fed automatically into the part of the burning assemblage which is the hottest, whereby to promote ignition of the charcoal.

• An ignition ring 22, consisting of a combustible material surrounds the inner chimney.
• the inner chimney insert 14 resides inside of the inner chimney 16 and possesses a safety match 23 and a match strike pad 15 at the top.
• the inner chimney insert 14 additionally provides structural support to the heat source 10 so that it may be stacked during transport.
• FIGURE 5 depicts the flaps 24 located at the base 26 of the heat source 10.
• the flaps 24 are meant to promote ignition of the inner chimney flue 16.
• the result therefore, is an integrated and economical ignition system, including inner chimney 16, outer wall 18, ignition ring 22, inner chimney insert 14 with safety match 23 and strike pad 15, and flaps 24.
• FIGURE 6 shows the heat source 10 when disassembled, including the open top 12 bounded by the outer wall 18, with the inner chimney insert 14 removed and opened, revealing the included safety matches 23 meant to be used to ignite the heat source 10.

• FIGURE 9 shows a possible configuration of the heat source 10 before ignition. With the bag opening 12 fully extended, the ignition ring 22 surrounds the inner chimney flue 16, which is bounded by the outer wall 18. The package then rests on top of the inner chimney insert 14 to promote ignition and sustained burning of the charcoal-based fuel that is contained by the heat source 10.

• the heat source 10 filled with charcoal-based fuel 28 may be placed in a grill 30.
• heat source 10 begins to catch flame.

• An inner flue is defined by the chimney structure for receiving air for igniting and burning the charcoal-based fuel.
• An outer chimney flue is defined by the outer wall of the first combustible inner, vertical, upright, chimney structure and the inner wall of the second combustible, vertical, upright wall structure, the outer chimney for exhausting combustion fumes from the charcoal- based fuel.
• a bottom wall member is secured to the inner chimney flue and the outer chimney flue and formed of a combustible material so as to be consumed during the ignition and burning of the charcoal-based fuel.

• One particularly advantageous aspect of heat source 10 includes the ability to be formed from comparatively inexpensive materials using comparatively inexpensive and efficient manufacturing techniques.
• prior combustible heat sources may include some of the novel features of the disclosed subject matter, none show the desirable attributes heat source 10 that may be formed of prefabricated paperboard or similar material from which the inner chimney 16 and inner chimney insert 14 are formed and the paper or similar material from which all the outer walls 18 may be formed.
