Fire pit liner and method of using the same
View Patent ↗A fire pit liner is provided herein. The fire pit liner can comprise a non-flammable material liner in a non-expandable uniform circular bowl-shape which is collapsible into the form of a bag. There is also provided a method of operating a fire pit employing the fire pit liner. The method can comprise providing a fire pit, providing the fire pit liner of the invention to the fire pit, conducting a fire in the fire pit, and collapsing the fire pit liner into the form of a bag, and optionally disposing of the bag.
1 . A fire pit liner comprising a non-flammable material liner in a non-expandable uniform circular bowl-shape which is collapsible into the form of a bag, and wherein the fire pit liner has a non-flammable threading material threaded through a smaller circumference of the fire pit liner than the full circumference of the fire pit material and wherein the threading material is a metal material in a wire form which is of an increased strength compared to the strength of the fire pit liner material.
2 . The fire pit liner of claim 1 wherein the non-flammable material liner is made of a material selected from the group consisting of metal, glass and ceramic.
3 . The fire pit liner of claim 1 , wherein the non-flammable material liner is a metallic paper made of tempered aluminum foil having a thickness within the gauge range of 0.001 inches to 0.005 inches and a tempering which is in the range of 50% to 100%.
4 . The fire pit liner of claim 1 wherein the liner is circular and is configured to have a diameter which is larger than the diameter of the fire pit to which it is to be applied.
5 . The fire pit liner of claim 1 , wherein the size of the non-expandable uniform circular bowl-shaped fire pit liner has a depth of from about 2 inches to about 12 inches.
6 . The fire pit liner of claim 1 , wherein the non-expandable uniform circular bowl-shaped fire pit liner is formed by hand by pressing down on a flat circular fire pit liner material so as to conform the liner material to an interior concave surface of the underlying fire pit.
7 . A fire pit system comprising:
a fire pit liner comprising a non-flammable material liner in a non-expandable uniform circular bowl-shape which is collapsible into the form of a bag; and,
a fire pit, and wherein the fire pit liner has a non-flammable threading material threaded through a smaller circumference of the fire pit liner material than the full circumference of the fire pit material and wherein the threading is a metal material in a wire form which is of an increased strength compared to the strength of the fire pit liner material.
8 . The fire pit system of claim 7 , wherein the firepit is elevated by a number of legs.
9 . The fire pit system of claim 7 , wherein liner is configured in the fire pit as a protective cover to the underlying surface of a wood burning area of the fire pit.
10 . The fire pit system of claim 7 , wherein the uniform circular bowl-shaped fire pit liner is layered upon another underlying uniform circular bowl-shaped fire pit liner in a series of overlaid fire pit liners, the top layer of which is configured to be removed after one or more uses of the fire pit to expose the next unused fire pit liner.
11 . The fire pit system of claim 7 , wherein the threading material is selected from the group consisting of an aluminum, copper, steel, and brass wire of about 16-to-30-gauge wire.
12 . The fire pit system of claim 7 , wherein the threading material is a fire-resistant textile material made with any one or more of poly benzyl imidazole, aromatic polyamides, flame retardant cotton, coated nylon, phosphorus-containing natural or synthetic cords or ropes, melamine-containing cords or ropes, and modacrylic cords or ropes.
13 . A method of operating a fire pit comprising:
(a) providing a fire pit;
(b) providing the fire pit liner of claim 1 to the fire pit;
(c) conducting a fire in the fire pit; and,
(d) collapsing the fire pit liner into the shape of a bag.
14 . The method of claim 13 , wherein the step (b) of providing the fire pit liner comprises applying a flat circular metal paper material by pressing the metal paper material of the fire pit liner into the fire pit such that it is flush with the surface of the underlying fire pit.
15 . The method of claim 13 , wherein the step (d) of collapsing the fire pit liner into the shape of a bag comprises either cinching circumferential edge points of the non-expandable, uniform circular bowl-shaped fire pit liner, or pulling the metal material in a wire form which is of an increased strength compared to the strength of the fire pit liner material, and which has been threaded through the smaller circumference of the fire pit liner, in order to cinch the fire pit liner.
16 . The method of claim 13 , further comprising discarding the fire pit liner in the form of a pouch.
17 . A method of operating a fire pit comprising:
(a) providing a fire pit;
(b) providing a fire pit liner comprising a non-flammable material liner in a non-expandable uniform circular bowl-shape which is collapsible into the form of a bag to the fire pit and wherein the fire pit liner has a non-flammable threading material threaded through a smaller circumference of the fire pit liner material than the full circumference of the fire pit material and wherein the threading material is a metal material in a wire form which is of an increased strength compared to the strength of the fire pit liner material;
(c) conducting a fire in the fire pit; and,
(d) collapsing the fire pit liner into the shape of a bag.
18 . The method of claim 17 , wherein the step (d) of collapsing the fire pit liner into the shape of a bag comprises either cinching circumferential edge points of the non-expandable, uniform circular bowl-shaped fire pit liner, or pulling the metal material in a wire form which is of an increased strength compared to the strength of the fire pit liner material, and which has been threaded through the smaller circumference of the fire pit liner, in order to cinch the fire pit liner.
