Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
97 words
A cigarette-simulating smokeable device for releasing an aerosol into the mouth of a smoker comprising: (a) a rod of fuel having a longitudinally extending passage therethrough; (b) a chamber in gaseous communication with an end of the passage whereby during smoking hot gases from the burning fuel rod enter the chamber (c) inhalant material located in the chamber which, when contacted by the hot gases during smoking forms an aerosol for inhalation by the smoker, (d) the chamber having at an end remote from the fuel rod a mouth-end closure member which is permeable to the aerosol.
Claim 2
Dependent Claim
97 words
A cigarette-simulating smokeable device for releasing an aerosol into the mouth of a smoker comprising: (a) a rod of fuel having a longitudinally extending passage therethrough; (b) a chamber in gaseous communication with an end of the passage whereby during smoking hot gases from the burning fuel rod enter the chamber (c) inhalant material located in the chamber which, when contacted by the hot gases during smoking forms an aerosol for inhalation by the smoker, (d) the chamber having at an end remote from the fuel rod a mouth-end closure member which is permeable to the aerosol.
Claim 3
Dependent Claim
42 words
A device as claimed in claim 1 in which the chamber and the mouth-end closure member are of unitary construction and may be formed by moulding or extruding a conventional smoke filter plug to provide a chamber to contain the inhalant material.
Claim 4
Dependent Claim
23 words
A device as claimed in claim 1 in which the fuel rod is a moulding or extrusion of reconstituted tobacco and/or tobacco substitute.
Claim 5
Dependent Claim
19 words
A device as claimed in claim 3 in which the wall of the fuel rod is impermeable to air.
Claim 6
Dependent Claim
49 words
A device as claimed in claim 1 in which the inhalant material comprises nicotine source material whose composition lies within the range 30-60% by weight of a solution of nicotine source material in triacetin or benzyl benzoate encapsulated in 40-70% by weight of gum acacia or a modified starch.
Claim 7
Dependent Claim
36 words
A device as claimed in claim 5 in which the inhalant material further comprises microcapsules formed by the coacervation method which capsules comprise 50-80% by weight of flavourant in a mixture of gelatin and gum acacia.
Claim 8
Independent Claim
25 words
A device as claimed in any preceding claim in which the end of the fuel rod to be lighted is closed by a combustible member.
Claim 9
Dependent Claim
50 words
A device as claimed in claim 1 in which the inhalant material comprises spray dried granules of flavourant whose composition lies within the range 30-60% by weight of a solution of flavourant and triacetin or benzyl benzoate and capsulated in 40-70% by weight of gum acacia or a modified starch.
