Abstract

Abstract An improved nicotine dispensing device for non-pyrolytic use which is adapted to release nicotine-bearing vapors into air drawn through the device. The device comprises one or more nicotine-bearing sections, one or more insulating sections which are linearly aligned with nicotine-bearing sections and a fluid impermeable housing. The housing retains the nicotine-bearing and insulating sections. This invention also includes a method for the preparation of an improved nicotine dispensing device. The method includes the steps of preparing one or more fluid retaining sections and one or more insulating sections. The fluid retaining sections and insulating sections are linearly arranged and wrapped with a fluid impermeable housing material. A nicotine containing material is then injected into, or incorporated within, the fluid retaining sections.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 143 words
An improved nicotine dispensing device for nonpyrolytic use, said device being adapted to release nicotine-bearing vapors into air drawn through said device, said device comprising: (a) one or more nicotine-bearing sections containing from 1 to 30 mg. of nicotine, characterized by the presence of a fibrous material, said fibrous material being selected from the group consisting of: polyester tow, cellulose acetate, polypropylene and combination thereof; (b) one or more insulating sections made from a material which is chemically inert to nicotine and wherein said insulating sections are linearly aligned with said nicotine-bearing sections and are arranged to be sequentially alternating with said nicotine bearing sections; and (c) a fluid impermeable housing, said housing retaining said nicotine bearing and insulating sections, and housing being formed from a laminar flexible material, said material including at least one paper layer and at least one polymer layer.
Claim 2
Dependent Claim 143 words
An improved nicotine dispensing device for nonpyrolytic use, said device being adapted to release nicotine-bearing vapors into air drawn through said device, said device comprising: (a) one or more nicotine-bearing sections containing from 1 to 30 mg. of nicotine, characterized by the presence of a fibrous material, said fibrous material being selected from the group consisting of: polyester tow, cellulose acetate, polypropylene and combination thereof; (b) one or more insulating sections made from a material which is chemically inert to nicotine and wherein said insulating sections are linearly aligned with said nicotine-bearing sections and are arranged to be sequentially alternating with said nicotine bearing sections; and (c) a fluid impermeable housing, said housing retaining said nicotine bearing and insulating sections, and housing being formed from a laminar flexible material, said material including at least one paper layer and at least one polymer layer.
Claim 3
Dependent Claim 26 words
The improved nicotine dispensing device of claim 1 wherein said fibrous material is configured to permit the free flow of air drawn through said dispensing device.
Claim 4
Dependent Claim 31 words
The improved nicotine dispensing device of claim 1 wherein the configuration of said insulating sections and said nicotine bearing sections are designed to simulate the pressure drop associated with conventional cigarettes.
Claim 5
Dependent Claim 30 words
The improved nicotine dispensing device of claim 1 wherein the material forming said polymer layer is selected from the group consisting of: cellulose acetate, polypropylene, polyester, polyethylene and combinations thereof.
Claim 6
Dependent Claim 45 words
The improved nicotine dispensing device of claim 1 wherein said laminar, flexible material includes two paper layers separated by a polyester layer, said paper layers permitting the attachment of said flexible material to the outermost surface of said nicotine bearing sections and said insulating sections.
Claim 7
Dependent Claim 21 words
The improved nicotine dispensing device of claim 1 wherein said housing is adapted to simulate the appearance of a filter-tip cigarette.
Claim 8
Dependent Claim 181 words
An improved nicotine dispensing device for non-pyrolytic use, said device being adapted to release nicotine bearing vapors into air drawn through said device, said device comprising: (a) one or more nicotine bearing sections containing from 1 to 30 milligrams of nicotine, characterized by the presence of a fibrous material, said fibrous material being selected from the group consisting of: polyester tow, cellulose acetate, polypropylene and combinations thereof; said fibrous material being configured to permit the free flow of air drawn through said dispensing device; (b) one or more insulating sections made from a material which is chemically inert to nicotine and wherein said insulating sections are linearly aligned with said nicotine bearing sections and are arranged to be sequentially alternating with said nicotine-bearing sections; and (c) a fluid impermeable housing, said housing retaining said nicotine bearing and insulating sections, said housing being formed from a laminar flexible material that includes two paper layers separated by a polyester layer, said paper layers permitting the attachment of said flexible material to the outermost surface of said nicotine bearing sections and said insulating sections.
Claim 9
Dependent Claim 181 words
An improved nicotine dispensing device for non-pyrolytic use, said device being adapted to release nicotine bearing vapors into air drawn through said device, said device comprising: (a) one or more nicotine bearing sections containing from 1 to 30 milligrams of nicotine, characterized by the presence of a fibrous material, said fibrous material being selected from the group consisting of: polyester tow, cellulose acetate, polypropylene and combinations thereof; said fibrous material being configured to permit the free flow of air drawn through said dispensing device; (b) one or more insulating sections made from a material which is chemically inert to nicotine and wherein said insulating sections are linearly aligned with said nicotine bearing sections and are arranged to be sequentially alternating with said nicotine-bearing sections; and (c) a fluid impermeable housing, said housing retaining said nicotine bearing and insulating sections, said housing being formed from a laminar flexible material that includes two paper layers separated by a polyester layer, said paper layers permitting the attachment of said flexible material to the outermost surface of said nicotine bearing sections and said insulating sections.
