Abstract
Abstract A reusable burner device which provides a flame for warming or cooking food or liquids, which includes a canister carrying fuel such as diethyleneglycol (D.E.G.) or mineral spirits, with a burner assembly therein, which includes an unique wick structure which extends down into the fuel, which includes a plurality of parallel, co-planer strands containing a plurality of threads in side by side arrangement with a thermal conducting wire woven thereabout, which wick is set at a predetermined height to provide a hot flame with a fixed burn time. The device is provided with a cap to close off the burner assembly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
204 words
In a reusable burner device for burning liquid fuel which includes a hollow, cylindrical reservoir open at one end with a bottom wall to close off the reservoir, and which contains liquid fuel for burning, a burner assembly attached to said reservoir in fluid tight relation, and closing off the open end of the reservoir, said burner assembly includes a top wall, with a hollow projection extending therefrom and which is open at both its upper and its lower ends, a wick holder plate engaged with said projection closing off said upper end opening, said wick holder plate has a transverse slit therein, at least one row of teeth extending across said slit, the improvement which comprises: wick means carried by said plate extending through said slit engaged by said teeth, with a tip at a predetermined height above said plate and extending down into said fuel, said wick means includes a wick having a plurality of parallel, co-planar strands containing a plurality of threads in side by side arrangement, and at least one length of thermal conducting wire woven about said strands to retain them together in co-planar configuration, and which extends down into said fuel to carry heat down into said fuel.

In a reusable burner device for burning liquid fuel which includes a hollow, cylindrical reservoir open at one end with a bottom wall to close off the reservoir, and which contains liquid fuel for burning, a burner assembly attached to said reservoir in fluid tight relation, and closing off the open end of the reservoir, said burner assembly includes a top wall, with a hollow projection extending therefrom and which is open at both its upper and its lower ends, a wick holder plate engaged with said projection closing off said upper end opening, said wick holder plate has a transverse slit therein, at least one row of teeth extending across said slit, the improvement which comprises: wick means carried by said plate extending through said slit engaged by said teeth, with a tip at a predetermined height above said plate and extending down into said fuel, said wick means includes a wick having a plurality of parallel, co-planar strands containing a plurality of threads in side by side arrangement, and at least one length of thermal conducting wire woven about said strands to retain them together in co-planar configuration, and which extends down into said fuel to carry heat down into said fuel.
Claim 3
Dependent Claim
24 words
A burner device as defined in claim 1 in which said reservoir is formed of a lightweight metallic material compatible with said liquid fuel.
Claim 4
Dependent Claim
24 words
A burner device as defined in claim 1 in which removable cap means are provided to close off said upper end of said projection.
Claim 5
Dependent Claim
32 words
A burner device as defined in claim 1 in which said wick holder plate has vent means to provide for pressure differences and to permit fuel to flow back into said reservoir.
Claim 6
Dependent Claim
33 words
A burner device as defined in claim 1 in which said slit is provided with two rows of complemental teeth which extend toward the middle of said slit to engage said wick means.
Claim 7
Dependent Claim
25 words
A burner device as defined in claim 1 in which said co-planar strands are of fiberglass threads, and said lengths of wire are of copper.
Claim 8
Dependent Claim
40 words
A burner device as defined in claim 3 in which said cap means includes a plurality of external threads on said hollow projection, and a cap to engage said threads to close off said projection above said wick holder plate.
Claim 9
Dependent Claim
23 words
A burner device as defined in claim 1 in which said wick is folded back on itself prior to passing through said slit.
Claim 10
Dependent Claim
25 words
A burner device as defined in claim 1 in which said wick means has at least a portion thereof in contact with said bottom wall.
Claim 11
Dependent Claim
28 words
A burner device as defined in claim 1 in which said threads when heated neutralize changes in the gravitational pull as the fuel level drops in the reservoir.
