Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 81 words
A fireworks device comprising: a body comprised substantially of a polyethylene material, said polyethylene material comprising the primary, active pyrotechnic ingredient of said fireworks device; suspension means connected to said body; ignition means connected to said body and being exposed; and said suspension means and said ignition means being oriented relative to one another and to said body such that said ignition means is located generally at the bottom of said body when said body is suspended by said suspension means.
Claim 2
Dependent Claim 81 words
A fireworks device comprising: a body comprised substantially of a polyethylene material, said polyethylene material comprising the primary, active pyrotechnic ingredient of said fireworks device; suspension means connected to said body; ignition means connected to said body and being exposed; and said suspension means and said ignition means being oriented relative to one another and to said body such that said ignition means is located generally at the bottom of said body when said body is suspended by said suspension means.
Claim 3
Dependent Claim 23 words
A fireworks device as recited in claim 1 wherein the polyethylene of said body has average molecular weight of less than about 100,000.
Claim 4
Dependent Claim 22 words
A fireworks device as recited in claim 2 wherein the polyethylene of said body has an average molecular weight of about 25,000-50,000.
Claim 5
Dependent Claim 47 words
A fireworks device as recited in claim 3 wherein: said body defines spaced top and bottom surfaces; said suspension means comprising a hanger embedded in and extending from said top of said body; and said ignition means comprising a wick embedded in and extending from said bottom.
Claim 6
Dependent Claim 58 words
The fireworks display device of claim 4 comprising: shield means of a material of sufficiently low combustibility to resist heat and splatterings from said body when it is burning, said shield means shielding at least the sides of said body from exposure to wind such that when the body is aflame, the flame does not readily blow out.
Claim 7
Dependent Claim 20 words
A fireworks device as recited in claim 5 wherein said shield means has spaced openings for ventilating and emitting light.
Claim 8
Dependent Claim 58 words
The fireworks display device of claim 1 comprising: shield means of a material of sufficiently low combustibility to resist heat and splatterings from said body when it is burning, said shield means shielding at least the sides of said body from exposure to wind such that when the body is aflame, the flame does not readily blow out.
Claim 9
Dependent Claim 47 words
A fireworks device as recited in claim 1 wherein: said body defines spaced top and bottom surfaces; said suspension means comprising a hanger embedded in and extending from said top of said body; and said ignition means comprising a wick embedded in and extending from said bottom.
Claim 10
Dependent Claim 114 words
A fireworks device as recited in claim 8 further comprising: said body having an elongated candle shape with one end of said candle comprising said top surface and the other said bottom surface; a shield of a material of sufficiently low combustibility to resist heat and splatterings from said body when it is burning, said shield means having a hollow cylindrical shape with an open end partially enclosing said body, the central axis of said shield being approximately aligned with the central axis of said body, the open end of the shield exposing the end of said body containing said wick, for shielding said body from wind and preventing lateral splattering of burning polyethylene.
Claim 11
Dependent Claim 20 words
A fireworks device as recited in claim 9 wherein said shield means has spaced openings for ventilating and emitting light.
Claim 12
Dependent Claim 45 words
A fireworks device as recited in claim 1 wherein said body has a generally longitudinal elongated shape with a plurality of protrusions extending vertically downward, said ignition means comprising a wick embedded in each protrusion and extending from generally the lowest portion of said protrusion.
Claim 13
Dependent Claim 36 words
A fireworks device as recited in claim 11 further comprising: a shield laterally surrounding the top and sides of said elongated shaped body and leaving the bottom of said protrusions of said elongated shaped body exposed.
Claim 14
Dependent Claim 14 words
The fireworks device of claim 1 in which said polyethylene is low density polyethylene.
Claim 15
Dependent Claim 26 words
The fireworks device of claim 13 in which said low density polyethylene has a density of from about 0.910 to about 0.925 grams per cubic centimeter.
Claim 16
Dependent Claim 140 words
A fireworks device comprising: a body made of a substantially polyethylene flame dripping material; suspension means connected to said body; ignition means connected to said body and being exposed; said suspension means and said ignition means being oriented relative to one another and to said body such that said ignition means is located generally at the bottom of said body when said body is suspended by said suspension means; and shield means of a material of sufficiently low combustibility to resist heat and splatterings from said body when it is burning said shield means housing said body in spaced relationship thereto for protecting said body from the wind, and said shield means being open at the bottom so as to expose the bottom of said body and said ignition means to said body can be ignited and drip flaming material.
Claim 17
Dependent Claim 140 words
A fireworks device comprising: a body made of a substantially polyethylene flame dripping material; suspension means connected to said body; ignition means connected to said body and being exposed; said suspension means and said ignition means being oriented relative to one another and to said body such that said ignition means is located generally at the bottom of said body when said body is suspended by said suspension means; and shield means of a material of sufficiently low combustibility to resist heat and splatterings from said body when it is burning said shield means housing said body in spaced relationship thereto for protecting said body from the wind, and said shield means being open at the bottom so as to expose the bottom of said body and said ignition means to said body can be ignited and drip flaming material.
Claim 18
Dependent Claim 20 words
A fireworks device as recited in claim 15 wherein said shield means has spaced openings for ventilating and emitting light.
