A tipping material for such a smoking article is also disclosed.

Abstract: A smoking article (10) comprises a rod (12) of smokeable material and a filter (14) attached to one end of the rod. The filter comprises an elongate body of filter material (16) wrapped with a transparent plug wrap (18). A first tipping wrapper (20a) overlies the join between the rod and the filter to attach the filter to the rod. At least one additional tipping wrapper (20b) is provided around the filter, spaced from and separate to the first tipping wrapper such that a portion of the transparent plug wrap is exposed between the first and at least one additional tipping wrapper to define a window portion (22) through which the filter material is visible. A method of producing such a smoking article is also disclosed.

Abstract: The present invention concerns an at least partially transparent cigarette filter tipping film comprising a biodegradable substrate, and softener in an amount of less than 25% by weight of the biodegradable substrate, and a cigarette filter comprising a filtration material encased in a cylinder of the said tipping film.

Abstract: Provided herein are compositions for removal of contaminants from an air stream. The composition contains a filtration agent having one or more components that can adsorb tar or other contaminants from smoke. Also provided is a method for removing a contaminant from an air stream. Also provided are a system and a kit employing the filtration agent.

Abstract: A filtered cigarette possesses at least one breakable capsule in its filter element. The filter element can possess a central cavity extending from the cigarette tobacco rod towards the middle of the filter element. The central cavity may be defined by an inner filter portion. The inner filter portion can be surrounded by an outer filter portion comprised of filter tow material that is generally permeable to the smoke generated by the cigarette. At least one breakable capsule is disposed in the central cavity of the filter element. The breakable capsules are spherical in shape, and are composed of a gelatin outer shell that encloses a payload of triglycerides and flavoring agents. The breakable capsules are adapted to rupture in response to pressure applied by the smoker to the outside region of the filter element.

Abstract: A system and associated method for analyzing a filter element of at least one of a filter rod and a smoking article is provided. At least one sensor element is adapted to interact with the filter element so as to determine an object insertion status with respect thereto and to generate an output signal in response. The object insertion status includes at least one of an object presence within the filter element, an object absence from the filter element, a proper insertion of an object into the filter element, a defective insertion of an object into the filter element, a proper object within the filter element, and a defective object within the filter element. An analysis unit is in communication with the at least one sensor element and responsive to the output signal therefrom to generate an indicia corresponding to the object insertion status.

Abstract: A smoking machine for smoking a smoking article is disclosed. The smoking machine comprises one or more electrochemical cells for analyzing the composition of a smoke stream from the smoking article. This can allow a gas or vapor phase chemical to be analyzed directly in real time without the need for pre-conditioning or preparation.

Abstract: A cigarette holder for extracting tar has first tar extractor with a stick and a first disc with apertures. A second tar extractor has a cylinder fitted to the stick and a second disc provided on one end of the cylinder and fitted in a flue of transparent resin. Smoke collision portions in the flue face the apertures. Smoke is compressed and accelerated when it passes through the apertures and expands again to collide with the smoke collision portions. It then collides with the second disc. Then the smoke is compressed and accelerated when it passes through the outer circumference of the second disc and the flue. Tar is extracted at each stage and the smoke is cooled by the second tar extractor before it reaches a mouth piece of the holder.

Abstract: A filter material for reducing the content of harmful substances in tobacco smoke. The filter material comprises a ground and not additionally activated expanded clay produced without adding foreign substances, and zeolite as the filter material. The filter is suitable for tobacco products such as cigarettes, cigars and cigarillos, and for smoking articles such as tobacco pipes and cigarette and cigar holders.

Abstract: An article is provided in which a flavor generating medium is electrically heated to combustion to evolve inhalable flavors or other components in vapor and/or aerosol form. The article has a plurality of charges of the flavor generating medium which are heated to combustion sequentially to provide individual puffs.

Abstract: An apparatus and method for removing toxic materials from tobacco which comprises a filter element which includes a seaweed. In use, the apparatus removes toxic materials from tobacco vapors which pass through the filter element.

Abstract: A smoke filter and a method for manufacturing the filter from a continuous multifilament filter tow are described in which a portion of the filter tow is treated with a dye to impart color to a discrete elongated zone of dye-treated filaments that is in substantial alignment with the longitudinal axis of the smoke filter.

Abstract: A device for discouraging cigarette smoking is disclosed comprising a cigarette filter having a mouthpiece oppositely disposed from a cigarette holder with a passageway therebetween. A filter paper is treated to be invisibly pervious only within the configurations of the letters of a word or words directed to the dangers of smoking. The treated filter paper is located in said passageway to close the free passage of smoke from the cigarette holder to the mouthpiece.The method of discouraging cigarette smoking is disclosed comprising the use of the foregoing structure wherein a cigarette is placed in the cigarette holder, the cigarette is lighted, and the smoke is withdrawn from the lighted cigarette so that the smoke from the lighted cigarette will move from the cigarette through the pervious portions of the filter paper, whereupon the letters of the words will entrap smoke particles so as to make the letters of the word or words visible.

Abstract: A cigarette holder having an attractive appearance and a compact structure suitable for use by ladies without any feel of reluctance, and capable of effectively removing nicotine and tar while permitting a visual check of the state of removal of nicotine and tar from the outside. A nicotine extractor made of a colored material, for removing the nicotine and tar by impact caused by collision of smoke, is fitted in a cigarette holder body made of a transparent material. When the colored nicotine extractor has become invisible from the outside of the cigarette holder body due to accumulation of nicotine and tars, the cigarette is no longer usable and can be discarded.

Abstract: A tar and nicotine filter device attachable to one end of a cigarette, including a molded, hard plastic tube for placing in a persons mouth, the tube containing two filter cartridges spaced apart by a tar trap therebetween, the invention in one design containing a cotton wad in the tar trap that is made to be visible so to inform a smoker when the device is tar saturated so to be discarded, and in another design of the invention, the tube is made of two interfitted pack so to allow opening and replacing the saturated cartridges.

Abstract: An improved smoking device comprising a container of smoking material, positioned juxtaposed to a viewing chamber that enables the observation of the trails of entrapped smoke and the determination of the amount of smoke in the viewing chamber. The smoke in the viewing chamber is forced into a smoke storage bag removed from the viewing chamber, when the smoker blows into a pipe stem. The blowing action mixes the smoke with the smoker's breath and provides an ideal smoke filled atmosphere in the bag which the smoker can then inhale.
