Abstract
Abstract Small, effective fire igniter tablets are provided comprising a major amount of a combination of wax and a cellulosic material powder in the form of a tablet or cylinder and a minor amount on and/or near the surface of said tablet or cylinder of an aliphatic diacyl peroxide. The tablets are found to readily ignite and burn for a sufficient time to insure kindling of logs or other solid fuel, both natural and synthetic.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A fire kindling tablet comprising a major amount of a wax-cellulosic wood powder composition, wherein said cellulosic wood powder is present in from about 40 to 80 weight percent and having on its surface from about 0.05 to 0.5 weight percent of said tablet of a peroxide-cellulosic wood powder composition comprised of a diacyl peroxide of at least 20 carbon atoms combined with a cellulosic wood powder, said diacyl peroxide being present in from 25 to 90 weight percent of said peroxide-cellulosic wood powder composition, wherein said wax has a melting point in the range of about 115° to 200° F.
Claim 2
Dependent Claim
101 words
A fire kindling tablet comprising a major amount of a wax-cellulosic wood powder composition, wherein said cellulosic wood powder is present in from about 40 to 80 weight percent and having on its surface from about 0.05 to 0.5 weight percent of said tablet of a peroxide-cellulosic wood powder composition comprised of a diacyl peroxide of at least 20 carbon atoms combined with a cellulosic wood powder, said diacyl peroxide being present in from 25 to 90 weight percent of said peroxide-cellulosic wood powder composition, wherein said wax has a melting point in the range of about 115° to 200° F.
Claim 3
Dependent Claim
58 words
A tablet according to claim 1, wherein said wood powder is a size less than 50 U.S. mesh, said wax has a melting temperature in the range of about 115° to 180° F and said tablet is formed by compressing together the wax-cellulosic wood powder composition with the peroxide-cellulosic wood powder composition coated on at least one side.
Claim 4
Dependent Claim
13 words
A tablet according to claim 2 wherein said diacyl peroxide is lauroyl peroxide.
Claim 5
Dependent Claim
29 words
A tablet according to claim 1, wherein said tablet has a minimum dimension of at least one-half inch and a maximum dimension of not more than about 4 inches.
Claim 6
Dependent Claim
52 words
A tablet according to claim 1, substantially in the form of a cylinder, wherein said wood powder of a size less than about 50 U.S. mesh, said wax has a melting temperature in the range of 115° to 180° F, and said cylinder is formed by compressing said wax-cellulosic wood powder composition.
Claim 7
Dependent Claim
23 words
A tablet according to claim 5, having at least one groove formed along the curved side filled with said peroxide-cellulosic wood powder composition.
Claim 8
Dependent Claim
31 words
A tablet according to claim 5, wherein at least one end coated with said peroxide-cellulosic wood powder composition, which is compressed simultaneously with the compression of said wax-cellulosic wood powder composition.
Claim 9
Dependent Claim
96 words
A fire kindling tablet comprising a major amount of a wax-cellulosic powder composition, wherein said cellulosic powder is present in from about 40 to 80 weight percent and having on its surface from about 0.05 to 0.5 weight percent of said tablet of a peroxide-cellulosic powder composition comprised of a diacyl peroxide of at least 20 carbon atoms combined with a cellulosic powder, said diacyl peroxide being present in from 25 to 90 weight percent of said peroxide-cellulosic powder composition, wherein said wax has a melting point in the range of about 115° to 200° F.
Claim 10
Dependent Claim
96 words
A fire kindling tablet comprising a major amount of a wax-cellulosic powder composition, wherein said cellulosic powder is present in from about 40 to 80 weight percent and having on its surface from about 0.05 to 0.5 weight percent of said tablet of a peroxide-cellulosic powder composition comprised of a diacyl peroxide of at least 20 carbon atoms combined with a cellulosic powder, said diacyl peroxide being present in from 25 to 90 weight percent of said peroxide-cellulosic powder composition, wherein said wax has a melting point in the range of about 115° to 200° F.
Claim 11
Dependent Claim
31 words
A fire kindling tablet in accordance with claim 8, wherein said cellulosic powder is formed from a member selected from the group consisting of wood, leaves, straw, nuthulls and rice hulls.
