Abstract

Fire ignition systems, combustible ignition structures, and methods of manufacturing and using such systems and devices are disclosed herein. In various embodiments, a fire ignition system may include a combustible container and a combustible ignition structure removably insertable into an interior of the combustible container. In various embodiments, the combustible ignition structure may include a base having a top surface and a chimney extending from the top surface. In various embodiments, the chimney may have an inner flue, a top opening into the flue, and an aperture through a side of the chimney into the flue. Other embodiments may be disclosed herein.

First claim

What is claimed is:

1. A fire ignition system, comprising:
a combustible container; and
a combustible ignition structure removably insertable into an interior of the combustible container and including:
a base having a top surface; and
a chimney extending from the top surface, the chimney having an inner flue, a top opening into the flue, and an aperture through a side of the chimney, wherein the aperture through the side of the chimney is closer to the top surface of the base than a top of the chimney and wherein the chimney includes at least four side walls, each side wall including an aperture through the side wall closer to the top surface of the base than the top of the chimney.

2. The fire ignition system of claim 1 , further comprising an insert removably insertable into the flue of the chimney and including a top flap sized to at least partially block the top opening of the chimney.

3. The fire ignition system of claim 2 , wherein the top flap connects two elongate planar pieces that are foldable to be parallel to each other and perpendicular to the top flap.

4. The fire ignition system of claim 2 , wherein the elongate planar pieces are sized similarly to one or more walls of the chimney.

5. The fire ignition system of claim 2 , further comprising an ignition device removably retainable in the flue of the chimney with the insert.

6. The fire ignition system of claim 5 , further comprising a striking surface mounted on a surface of the insert or the chimney, wherein the ignition device is a match.

7. The fire ignition system of claim 6 , wherein the match is a long-stemmed match.

8. The fire ignition system of claim 1 , wherein portions of the top surface of the base on opposite sides of the chimney slope away from the chimney.

9. The fire ignition system of claim 8 , wherein the portions of the top surface sloping away from the chimney form two sides of a generally triangular cross section of the base.

10. The fire ignition system of claim 1 , wherein the chimney and base are constructed with a single piece of foldable material.

11. A fire ignition system, comprising:
a combustible container;
solid fuel insertable into the combustible container; and
a combustible ignition structure constructed with a single piece of foldable material removably insertable into an interior of the combustible container and including:
a base having a top surface; and
a chimney extending from the top surface, the chimney having an inner flue, a top opening into the flue, and an aperture through a side of the chimney wherein the combustible ignition structure is ignitable to ignite the solid fuel, wherein the chimney includes at least four side walls, each side wall including an aperture through the side wall closer to the top surface of the base than the top of the chimney.

12. The fire ignition system of claim 11 , further comprising an insert removably insertable into the flue of the chimney and including a top flap sized to at least partially block the top opening of the chimney.

13. The fire ignition system of claim 12 , wherein the top flap connects two elongate planar pieces that are foldable to be parallel to each other and perpendicular to the top flap.

14. The fire ignition system of claim 12 , wherein the elongate planar pieces are sized similarly to one or more walls of the chimney.

15. The fire ignition system of claim 12 , further comprising an ignition device removably retainable in the flue of the chimney with the insert.

16. The fire ignition system of claim 15 , further comprising a striking surface mounted on a surface of the insert or the chimney, wherein the ignition device is a match.

17. The fire ignition system of claim 16 , wherein the match is a long-stemmed match.

18. The fire ignition system of claim 11 , wherein portions of the top surface of the base on opposite sides of the chimney slope away from the chimney.

19. The fire ignition system of claim 18 , wherein the portions of the top surface sloping away from the chimney form two sides of a generally triangular cross section of the base.

20. A fire ignition system, comprising:
a combustible bag defining an interior and a bottom surface having a footprint;
a combustible ignition structure comprising a foldable cardboard sheet, said combustible ignition structure being removably insertable into an interior of the combustible bag and including:
a base having a similar footprint as the combustible bag; and
a chimney extending from a center of the base and having a top opening into an inner flue;
wherein the chimney is defined by a first portion of the foldable cardboard sheet, the first portion having a plurality of subsections within the first portion, where opposed end subsections of the first portion are joined to form the chimney having an elongate chimney shape with a central opening therethrough, each of the subsections defining the sidewalls of the chimney, and
wherein the base is defined by a second portion of the foldable cardboard sheet, the second portion of the foldable cardboard sheet extending from the first portion of the foldable cardboard sheet, the second portion having a bottom opening through which the chimney defined by the first portion of the foldable cardboard sheet extends.

21. The fire ignition system of claim 20 , further comprising solid fuel insertable into the combustible bag about the chimney, to be between the bag and the chimney.

22. The fire ignition system of claim 20 , wherein the combustible ignition structure comprises a single continuous foldable cardboard sheet.
