Abstract
Abstract A non-combustible simulated cigarette inhaler device includes a hollow cylindrical tube having an open air inlet end and an opposed open air outlet end to be placed in the mouth of a user. A first element of air permeable material is located within the hollow tube across a segment of the transverse cross-sectional area of the tube and a second element of air permeable material is located within the hollow tube across the remaining segment of the transverse cross-section of the tube. The first element is impregnated with a nicotine free base material. The second element is impregnated with an acid which is reactive with the free base to form a salt having a pH in the range of approximately 5 to 7. Examples of such acids are 2-butenoic acid, 2-methyl-2-butenoic acid, isocaproic, caproic, and caprylic acids.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
A non-combustible simulated cigarette inhaler device comprising: a hollow cylindrical tube having an open air inlet end and an opposed open air outlet end; a first element of air permeable material located within the tube across a segment of the transverse cross-sectional area of the tube; a volatilizable nicotine free base material impregnating the first element; a second element of air permeable material located within the tube next to the first element substantially across the remaining segment of the transverse cross-sectional area of the tube; and, a volatilizable acid impregnating the second element which acid is reactive with the nicotine free base to form a salt having a pH in generally the range of approximately 5 to approximately 7.
Claim 2
Dependent Claim
119 words
A non-combustible simulated cigarette inhaler device comprising: a hollow cylindrical tube having an open air inlet end and an opposed open air outlet end; a first element of air permeable material located within the tube across a segment of the transverse cross-sectional area of the tube; a volatilizable nicotine free base material impregnating the first element; a second element of air permeable material located within the tube next to the first element substantially across the remaining segment of the transverse cross-sectional area of the tube; and, a volatilizable acid impregnating the second element which acid is reactive with the nicotine free base to form a salt having a pH in generally the range of approximately 5 to approximately 7.
