Filter apparatus for removing tar and other deleterious substances from tobacco smoke

Abstract

Abstract Apparatus is disclosed for removing tars and other deleterious material from tobacco smoke including a cylindrical housing including an entrance chamber for receiving the tobacco product, such as a cigarette, and terminated at the inner end by a disk having a selected number of apertures therethrough for the passage of tobacco smoke. Further, channels are disposed within the disk to direct the flow of smoke from the end of the tobacco product into the apertures. An annular smoke guide is disposed on the rearward side of the aforementioned disk to present an edge onto which the smoke is directed by the disk apertures, whereby the tars and various deleterious products may be deposited. Further, the smoke is further drawn through a porous filter, whereby any remaining deleterious products may be absorbed. Such filter apparatus may be mounted within a holder including a mouthpiece having a passage therethrough in communication with the aforedescribed filter apparatus. In one illustrative embodiment, the mouthpiece is connected to a resilient bushing and is resiliently biased against an end of the filter apparatus to assure that air does not leak about the outer surface of the tobacco product and filter apparatus. In addition, the holder includes a cavity for mounting therein the filter apparatus and for facilitating the rectilinear movement of the mouthpiece to thereby enable the aforedescribed filter apparatus to be ejected therefrom. In one illustrative embodiment, the cigarette receiving opening of the cavity has therein a resilient holding projection for securing the filter apparatus within the cartridge, but permitting upon actuation of the mouthpiece member, the rejection therethrough of the filter apparatus.
