Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
In a material vapor generator with heat accelerated and controlled vapor release: a reservoir material; vaporizable material impregnated in said reservoir material subject to activation by heat source means; positioning means holding said reservoir material for heat controlled vaporization release of said vaporizable material by heat from said heat source means; with said material vapor generator in the form of a lamp; and wherein said lamp is shaped for internal illumination with light source means supported by body means; and with said reservoir material in the form of side walling means supported by said body means in spaced relation from said light source means for air circulation in the space between said side walling means and said light source means.
Claim 2
Dependent Claim
120 words
In a material vapor generator with heat accelerated and controlled vapor release: a reservoir material; vaporizable material impregnated in said reservoir material subject to activation by heat source means; positioning means holding said reservoir material for heat controlled vaporization release of said vaporizable material by heat from said heat source means; with said material vapor generator in the form of a lamp; and wherein said lamp is shaped for internal illumination with light source means supported by body means; and with said reservoir material in the form of side walling means supported by said body means in spaced relation from said light source means for air circulation in the space between said side walling means and said light source means.
Claim 3
Dependent Claim
13 words
The material vapor generator of claim 1, wherein said reservoir material is wax.
Claim 4
Dependent Claim
44 words
The material vapor generator of claim 1, wherein said lamp is shaped for internal illumination with a lamp bulb on an electrical plug body; and sections of reservoir material of said walling means in the form of side walls attached to said electrical body.
Claim 5
Dependent Claim
28 words
The material vapor generator of claim 3, wherein said side walls are vaporizable material impregnated wax subject to slow vaporizing release of the vaporizable material with moderate heating.
Claim 6
Dependent Claim
19 words
The material vapor generator of claim 3, wherein said side walls are vaporizable material impregnated porous plastic material walls.
Claim 7
Dependent Claim
22 words
The material vapor generator of claim 1, wherein said vaporizable material is one of a vaporizable scent, air freshener or insecticide material.
Claim 8
Dependent Claim
22 words
The material vapor generator of claim 1, wherein said vaporizable material is a plurality of vaporizable scent, air freshener or insecticide materials.
