Abstract

Abstract A cigarette filter which can be adapted to any kind of cigarette, regular or filter, and be torn off if desired. It could be used for filtering smoke and selectively diluting said smoke with air. When used in combination with an ordinary cigarette, the resulting cigarette comprises a cylindrical tobacco roll, surrounded with its usual paper wrapper, and a filter. The filter is spacedly mounted at one end of the tobacco roll to define a hollow cylindrical inner space therebetween. Inside the hollow cylindrical inner space, there is a porous disc, in which the opposite faces are preferably both concave. This disc is positioned substantially half-way between the end of the cylindrical tobacco roll and the filter to divide the hollow cylindrical space into a first and a second smoke cooling chamber. Perforations are provided in the walls of both smoke cooling chambers and the perforations can at will be covered or uncovered to cause one or both chambers to become permeable to air. In this manner, when only filtering of the smoke is desired the filter cigarette is used as such. When smoke diluted with air is desired, the first cooling chamber is made permeable to air. Finally, if air exclusively is intended to be inhaled, both cooling chambers are rendered permeable to air thus precluding any substantial inhaling of smoke. The disclosure also relates to a filter cigarette adapted with the above supplementary filtering device.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 392 words
A filter cigarette intended for filtering smoke and selectively diluting said smoke with air comprising: a. a cylindrical tobacco roll surrounded with a paper wrapper; b. a filter; c. first means to mount said filter adjacent one end of said cylindrical tobacco roll and spaced therefrom, said first means including a masking tear strip means for permitting the removal of said filter from said tobacco roll, said tear strip means being mounted in sticking engagement over said paper wrapper; d. said first means defining a hollow cylindrical chamber between said one end of said tobacco roll and said filter; e. a circular porous disc positioned in said hollow cylindrical chamber substantially halfway between said one end of said tobacco roll and said filter; f. said circular porous disc dividing said hollow cylindrical chamber portion into a first smoke cooling chamber between said one end of said tobacco roll and said disc, said first smoke cooling chamber portion receiving smoke from said one end of said tobacco roll, and a second smoke cooling chamber portion between said disc and said filter, said second cooling chamber receiving smoke passing from said first smoke cooling chamber and through said disc; g. said first means including a pair of air permeable portions, each portion effecting communication between the exterior of said cigarette and one of said cooling chamber portions, said first means further including removable second and third means each of which cooperate with one of said air permeable portions to selectively seal said portions thereby blocking communication between the exterior of said cigarette and one of said cooling chamber portions whereby if no filtering of smoke is desired said first means and said filter are removed from said one end of said cylindrical tobacco roll by said tear strip means, if only filtering of said smoke is desired, the filter cigarette is used as such while said second and said third means are in place on said first means, if smoke diluted with air is desired said second means is removed to cause said first cooling chamber portion to be permeable to air, and if air in the substantial absence of smoke is intended to be inhaled, said second and said third means are removed to cause both said cooling chamber portions to be rendered permeable to air thus precluding any substantial inhaling of smoke.
Claim 2
Dependent Claim 392 words
A filter cigarette intended for filtering smoke and selectively diluting said smoke with air comprising: a. a cylindrical tobacco roll surrounded with a paper wrapper; b. a filter; c. first means to mount said filter adjacent one end of said cylindrical tobacco roll and spaced therefrom, said first means including a masking tear strip means for permitting the removal of said filter from said tobacco roll, said tear strip means being mounted in sticking engagement over said paper wrapper; d. said first means defining a hollow cylindrical chamber between said one end of said tobacco roll and said filter; e. a circular porous disc positioned in said hollow cylindrical chamber substantially halfway between said one end of said tobacco roll and said filter; f. said circular porous disc dividing said hollow cylindrical chamber portion into a first smoke cooling chamber between said one end of said tobacco roll and said disc, said first smoke cooling chamber portion receiving smoke from said one end of said tobacco roll, and a second smoke cooling chamber portion between said disc and said filter, said second cooling chamber receiving smoke passing from said first smoke cooling chamber and through said disc; g. said first means including a pair of air permeable portions, each portion effecting communication between the exterior of said cigarette and one of said cooling chamber portions, said first means further including removable second and third means each of which cooperate with one of said air permeable portions to selectively seal said portions thereby blocking communication between the exterior of said cigarette and one of said cooling chamber portions whereby if no filtering of smoke is desired said first means and said filter are removed from said one end of said cylindrical tobacco roll by said tear strip means, if only filtering of said smoke is desired, the filter cigarette is used as such while said second and said third means are in place on said first means, if smoke diluted with air is desired said second means is removed to cause said first cooling chamber portion to be permeable to air, and if air in the substantial absence of smoke is intended to be inhaled, said second and said third means are removed to cause both said cooling chamber portions to be rendered permeable to air thus precluding any substantial inhaling of smoke.
Claim 3
Dependent Claim 58 words
A filter cigarette as claimed in claim 1, wherein said first means comprise a filter wrapper which surrounds said filter and extends past said one end of said tobacco roll over said paper wrapper, said filter and said one end being spaced from one another and defining said hollow cylindrical chamber between said tobacco roll and said filter.
Claim 4
Dependent Claim 19 words
A filter cigarette as claimed in claim 2, wherein said removable second and third means comprise masking tear strips.
