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.

Claims

1. A filter ejector, comprising an inner member adapted at one end thereof to be held in the mouth of a smoker and having a passage for the flow of smoke therethrough, an outer tubular member, means for mounting a portion of said inner member within said outer tubular member for rectilinear sliding motion, said outer tubular member including at one end a projection on the inner surface thereof permitting a filter cartridge to be inserted within said outer tubular member and held therein by said projection, said filter cartridge including means permitting a cigarette to be inserted and held therein, and means normally biasing said inner member to a first position within said outer tubular member wherein said filter cartridge may be inserted within said outer tubular member while permitting the user to eject both the filter cartridge and cigarette by sliding said inner member to a second position against the force of said means normally biasing said inner member to said first position such that said inner member engages said cartridge and forces same through said projection thereafter causing said cartridge and cigarette to slide out of said one end of said outer tubular member.

2. A filter ejector as in claim 1, wherein said means normally biasing said inner member to a first position comprises a helical spring positioned between said inner and outer members, said outer tubular member having an abutment adapted to be engaged by one end of said spring and said inner member having an abutment adapted to be engaged by the other end thereof.

3. A filter ejector, comprising an inner member adapted at one end thereof to be held in the mouth of a smoker and having a passage for the flow of smoke therethrough, an outer tubular member, means mounting a portion of said inner member within said outer tubular member for rectilinear sliding motion, said outer tubular member including at one end a projection on the inner surface thereof permitting a filter cartridge to be inserted within said outer tubular member and held therein by said projection, said filter cartridge including means permitting a cigarette to be inserted and held therein, and means normally biasing said inner member towards said projection, the force of said means biasing said inner member being insufficient of itself to move said cartridge over said projection while permitting the user to eject both the filter cartridge and cigarette by sliding said inner member further within said outer tubular member in the direction in which the force of said means normally biasing said inner member acts such that said inner member engages said cartridge and forces same through said projection thereafter causing said cartridge and cigarette to slide out of said one end of said outer tubular member.

4. A filter ejecTor as in claim 3, wherein said means normally biasing said inner member to a first position comprises a helical spring positioned between said inner and outer members, said outer tubular member having an abutment adapted to be engaged by one end of said spring and said inner member having an abutment adapted to be engaged by the other end thereof.

5. A filter ejector as in claim 2, wherein said abutment formed as a part of said outer tubular member is spaced from said one end of said outer tubular member a distance approximating the length of said filter cartridge.

6. A filter ejector as in claim 4, including a second abutment formed as a part of said outer tubular member and extending inwardly thereof, said second abutment being spaced from said one end of said outer tubular member a distance approximating the length of said filter cartridge.
