Abstract

A simulated smoking device, adapted for non-burning or non-combustion uses, comprises: a container defining a passageway therethrough; a source of vaporizable nicotine in fluid communication; and means for preventing the evaporation of said nicotine during periods of non-use. The source of vaporizable nicotine may be an absorbent material which has a nicotine-bearing material absorbed therein. The absorbent may also have absorbed therein a pH adjustment, water and/or flavoring ingredients. The device, at ambient temperatures and pressures, releases nicotine vapors into air drawn through the passageway of the container during use.

Claims

2. The device of claim 1, wherein said nicotine-bearing material is selected from the group consisting of:

nicotine (d), nicotine (l), nicotine (dl), nicotine salts, and nicotine esters.

3. The device of claim 1, wherein ingredients for flavoring and pH adjustment of said nicotine-burning material are also absorbed into said absorbent material.

4. The device of claim 3, wherein said flavoring ingredients are selected from the group consisting of:

orange flavoring, lemon flavoring, menthol, spearmint flavoring, peppermint flavoring, and cinnamon flavoring.

5. The device of claim 1, wherein water is also absorbed into said absorbent material in order to provide for the humidification of said vapors to reduce the drying effect or said vapors on the mouth of a user.

6. The device of claim 1, further comprising:

a first closure at a first end of said passageway; and

a second closure at a second end of said passageway,

said closures being adapted to prevent evaporation of said nicotine-bearing material when said device is not in use.

7. The device of claim 6, wherein each of said closures comprises:

a resilient flap affixed to said container, said flap adapted to seal said passageway when air is not drawn through said passageway by said user and adapted to permit the flow of air through said passageway when air is drawn through said passageway by said user.

8. The device of claim 1, further comprising:

a first moisture seal at a first end of said passageway; and

a second moisture seal at a second end of said passageway.

9. The device of claim 8, wherein each of said seals comprises:

a porous plug disposed across said passageway, said plug being adapted to provide minimal resistance to the flow of gases therethrough and to substantially prevent the flow of liquids therethrough.

10. The device of claim 1, wherein said container is cylindrical in shape, having an outer diameter and a length selected to simulate the appearance of a conventional cigarette.

11. The device of claim 10, wherein said absorbent material comprises:

an absorbent cylinder having an external diameter corresponding to the inner diameter of said container.

12. The device of claim 10, wherein said absorbent material is recessed from the ends of said cylindrical container, thereby preventing contact between said member and the mouth of a user drawing air through said device.

13. The device of claim 10, further comprising:

a cylindrical band affixed around a first end of said cylinder, said band being adapted to simulate the appearance of a filter tip.

14. The device of claim 10, wherein said comprises:

a first tapered portion bounded by a first frustoconical sidewall and tapering inward from a first end of said container;

a second tapered portion bounded by a second frustoconical sidewall and tapering inward from a second end of said container; and

a central cylindrical portion communicating between said first portion and said second portion, the sidewall of said central portion being defined by said absorbent member.

15. The device of claim 14, wherein the diameter and length of said central portion are selected to provide a predetermined rate of vapor release from said mixture.

16. The device of claim 14, further comprising:

an annular divider disposed within said central portion; and

wherein said absorbent material comprises;

a first absorbent material disposed on a first side of said divider; and

a second absorbent material disposed on a second side of said divider;

said first and second absorbent members adapted to have separately absorbed therein a pair of compounds having incompatible characteristics.

17. The device of claim 16, wherein said divider is longitudinally positioned within said cylinder to control the relative amounts of surface area of said first and second absorbent materials exposed to said passageway, thereby controlling the relative amounts of vapor released from said first and second absorbent materials.

18. The device of claim 16, wherein the relative porosities of said first and second absorbent materials are selected to control the relative amounts of vapor released from said first and second members.

19. A simulated smoking device which is adapted for non-heating or non-combustion uses, comprising:

a container defining a passageway therethrough;

means containing a source of vaporizable nicotine, said means disposed within the container, and providing for the reduction of pressure of air drawn through the passageway;

said source being capable, when the device is not heated above ambient room temperature and in the absence of combustion, or releasing significant amounts of nicotine vapors into air drawn through said passageway by the user of said device.

20. The device of claim 19 wherein said source of vaporizable nicotine is capable, in the absence of tobacco, of releasing nicotine vapors into air drawn through said passageway.

21. The device of claim 20 wherein said nicotine is selected from the group consisting of nicotine (d), nicotine (l), nicotine (dl), nicotine salts, and nicotine esters.

22. The device of claim 21 wherein the ingredients for flavoring and pH adjustment of said nicotine are also included with said source.

23. The device of claim 22 wherein said flavoring ingredients are selected from the group consisting of orange flavoring, lemon flavoring, menthol, spearmint flavoring, peppermint flavoring and cinnamon flavoring.

24. The device of claim 23 wherein water is also included with said source of vaporizable nicotine in order to provide for the humidification of said vapors to reduce the drying effect of said vapors on the mouth of the user.

25. The device of claim 19, 20, 21, 22, 23 or 24, wherein said source of vaporizable nicotine comprises an absorbent material having nicotine absorbed therein.

26. The device of claim 19 further comprising:
