Patent number: 8201564Abstract: Fibrous material suitable for incorporation into filter elements of smoking articles such as cigarettes are impregnated with additives and agents such as flavorants, flavorant-enhancers and/or free radical scavengers. The fibrous material is contacted with the additive dispersed in a high pressure gas or supercritical fluid (SCF) held at elevated pressures. The high pressure gas or SCF swells the fibrous matrix and enables the additive to be incorporated within the matrix. When pressure is reduced, the gas or SCF vaporizes and leaves the additive embedded in the fiber interstices. As a result, the additive is slowly released over a finite period of time. When incorporated into a cigarette filter, the additive is released at a desired rate from the interior of the fibrous filter into the cigarette smoke.Type: GrantFiled: December 4, 2006Date of Patent: June 19, 2012Assignee: Philip Morris USA Inc.Inventors: Mark A.

Patent number: 7874296Abstract: Cigarette gas filter is used to filter the gaseous components of main stream smoke. This causes reduction of the delivery of the gaseous constituents of main stream smoke (MSS). The gas filter consists of a narrow annular gap, where the outer side is circumvented by a high permeability wrapper paper. As the cigarette smoke is passed through this annulus gap, the fraction of gases present in the smoke is reduced by diffusion mechanism and due to inflow of air into the annulus by convection mechanism. Since the diffusion coefficient of aerosol particles are several orders of magnitude smaller than the gas molecules, the aerosol particles are kept mainly intact while passing through the annulus. Therefore this filter is applied for reducing the gas/tar ratio. This filter can also be used to filter the gases of non-cigarette smokes.Type: GrantFiled: July 25, 2007Date of Patent: January 25, 2011Inventor: Mohammad Said Saidi
