Definitions

  • This invention relates to filters and the removal from tobacco smoke of poisons and other constituents that may be either harmful or distasteful to a smoker.
  • tobacco smoke contains various alkaloids and other poisonous materials such as nicotine and also tarry and other constituents which have a highly irritating effect on the mucous membranes of the smoker and frequently leave objectionable deposits in the respiratory system.
  • Other harmful constituents in tobacco smoke include carbon monoxide, ammonia, aldehydes, pyridine bases and pyrrole derivatives.
  • An object of this invention is to provide a tobacco smoke filter in which the filtering material is capable of removing poisons such as nicotine and other harmful con stituents from tobacco smoke in a highly improved and eflicient manner without so altering the smoke as to spoil its taste and appeal to the smoker.
  • Filtering materials that have been used heretofore for tobacco smoke remove constituents from the smoke by a purely physical absorption or adsorption and therefore, at best, remove only a limited proportion of the nicotine and other harmful constituents. Also it is characteristic of such materials to desorb or begin to give off again some of these poisonous materials after the filter material has been in use for a period of time.
  • Smoke filtering materials used or proposed heretofore include materials such as special kinds of porous paper, bentonite, molybdic acid and silica gel. At best, however,
  • these cation exchange materials are capable of removing nicotine and other volatile basic nitrogen compounds efficiently and selectively from a much larger quantity of tobacco smoke than the previously known physical or mechanical filter materials. These latter materials quickly become saturated and lose their ability to remove harmful constituents from the smoke, thus necessitating either frequent changes of the filtering material if used in cartridge form in some kind of a pipe stem, cigar or cigarette holder, or the use of larger quantities of the filtering material if employed in some kind of built in filter.
  • any of the organic cation exchange materials which have a reasonably high ion exchange capacity and are capable of being regenerated with acid and used in the hydrogen condition can be employed for filtering tobacco smoke with good results.
  • These products are well known for the conditioning of water and treatment of dilute solutions of chemicals, and are usually wter insoluble synthetic resins containing either sulfonic or carboxylic groups or both that exert chemical'ion exchange activity. it is possible to regenerate them with either a dilute solution of an acid or common salt.
  • the sulfonic group cation exchange resins and sulfonated coal are particularly eitective in accordance with my invention for filtering tobacco smoke and may be used in any suitable manner.
  • cation exchange material employed has an exchange capacity of at least 6'kilograins per cubic foot (expressed in terms of CaCO3). While my invention is not limited thereto, I have found that cation exchangers readily available on the market and highly efiective for my purposes include those of the sulfonated coal type and sulfonated resins such as the phenol formaldehyde, polystyrene and polyvinyl type resins. Such materials have been referred to in various publications including Ion Exchange by Nachod, published 1949 by Academic Press, Inc., and Ion Exchange Resins by Kunin and Myers, published 1950 by John Wiley '& Sons, Inc.
  • Cation exchangers may be manufacture-d in the form of granules or beads and usually are sold in granular form with the particles ranging in size from 16 to 50 mesh.
  • the exchangers may be used in this physical form and simply placed in an enclosure, housing or cartridge of some kind through which the tobacco smoke to be filtered is passed. If desired, these materials may be ground to finer particle sizes and either used alone or mixed with particles of inert or other substances.
  • a particularly efiicient way of utilizing these exchange materials and one that is made possible by their extremely efficient operation for long periods of time, is by depositing the finely ground material on some kind of a more or less porous carrier.
  • the exchange material may be ground very fine and made up into a slurry which is deposited on layers of fabric, paper or the like where it is allowed to dry.
  • the finely ground exchanger may be mixed with pulp or paper fibers, and this physical mixture dried to produce a light flufiy filtering medium.
  • the amounts of the cation exchanger used with such carriers may, of course, be varied greatly depending upon the way in which the material is to be used and the amount of nicotine and other basic substances that have to be removed from the smoke.
  • Smoke filters mode of these exchange materials ordinarily will be discarded after use.
  • it is possible to regenerate cation exchange materials by soaking them in a dilute solution of acid such as 3 to solution of hydrochloric or sulfuric acid. After this acid treatment, the resin may be air or force dried and again used for filtering smoke. It will be found that such materials will have as great a capacity for removing nicotine and other volatile basic nitrogen compounds from smoke after such regeneration as they had in their original state.
  • the ca ion exchanger to be used as a filter is not already in the hydrogen exchanging condition, it should be treated with a dilute solution of acid and air or force dried as in the procedure for regeneration before it is used in the filter.
  • the granular or finely divided filter material may be packed into removable filter cartridges which are placed in a special chamber in a pipe stem, in a cigarette holder, or in a cigar holder so that the smoke from the burning tobacco is drawn through the cartridge by the smoker.
  • the exchange material will be held in some form of enclosure or housing whether this be a part of the cigarette, cigar, holder or pipe or a separate removable cartridge.
  • the exchange material may be used in the filter in a variety of forms. For example, it may be used loose .in the form of finely divided particles, it may be deposited on a porous material such as silica gel, paper plugs, cork or'tobacco, or'it may be deposited on cringled paper or impregnated in such paper or even extruded in the form of fine fibers.
  • the filter material may also be used in the form of an extruded porous plug of the ion exchange resin. As will be apparent to those skilled in the art, the effectiveness of such .material for removing nicotine and other objectionable substances from the smoke depends to a large extent upon the contact between the smoke and the exchange material.
  • any-of the .above forms may be used in either built-in or removable filters in pipe stems or holders, or maybe used in filters built into the tip or one end of cigarettes, cigars or similar smoking materials as will be well understood by those skilled in the art.
  • a smoke filter containing simply the cation exchange material will be entirely satisfactory.
  • Such a filter will remove selectively the nicotine and other basic irritants from the smoke and impart a mildness to it without dehydrating the smoke or otherwise destroying its appeal to the smoker.
  • High boiling tars and hydrocarbons are also removed to some extent by mechanical filtering and condensing action common to all types of filters.
  • a method of removing poisons from tobacco smoke which comprises passing such smoke in a smoking article in contact with particles of a high capacity organic cation exchange material in the hydrogen exchanging condition.
  • a device for smoking tobacco having therein a tobacco smoke filter which comprises an enclosure through which smoke from burning tobacco is drawn, and finely divided high capacity cation exchange material in said enclosure as a filtering material for removing poisons from the smoke drawn therethrough, said exchange material being in the hydrogen exchanging condition.
  • a built-in cigarette filter containing high capacity acid regenerated cation exchange material as its principal active filtering material 3.
  • a cartridge for filtering tobacco smoke in a smoking article to remove poisons therefrom which contains high capacity acid regenerated cation exchange material as its principal filtering material.
  • a filter in a smoking pipe which contains as its principal filtering constituent hydrogen exchanging high capacity cation exchange material.
  • a filter for removing poisons from tobacco smoke in a smoking article which comprises cation exchange resin in the hydrogen exchanging condition deposited in dispersed form on a carrier of inert material to expose extensive areas of resin surface to contact with the smoke.
  • a filter for removing poisons from tobacco smoke in a smoking article which comprises finely ground hydrogen exchanging cation exchange resin deposited in dispersed form on paper.
  • a filter for removing poisons from tobacco smoke in a smoking article which comprises finely ground hydrogen exchanging cation exchange resin deposited in dispersed form on paper pulp fibres.
  • a smoking article having therein a tobacco smoke filter which comprises a housing with openings to permit smoke from burning tobacco to be drawn therethrough, and finely divided organic sulfonated cation exchange material in the hydrogen exchanging condition disposed therein so that smoke drawn through the housing passes in direct contact with such material.
  • a smoking article having therein a tobacco smoke filter which comprises a housing with openings to permit smoke from burning tobacco to be drawn therethrough, and finely divided organic carboxylic type cation exchange material in the hydrogen exchanging condition disposed therein so that smoke drawn through the housing passes in direct contact with such material.
  • a smoking article having therein a tobacco smoke filter which comprises a housing with openings to permit smoke from burning tobacco to be drawn therethrough, and finely divided cation exchange resin in the hydrogen exchanging condition disposed therein to filter poisons out of smoke drawn through the housing.
  • a cigarette having a built-in filter at one end thereof for removing poisons from smoke drawn therethrough, said filter containing as its principal active filtering material cation exchange material in the hydrogen exchanging condition.
  • a cigarette having a built-in filter at one end thereof for removing poisons from smoke drawn therethrough, said filter consisting essentially of cation exchange resin in the hydrogen exchanging condition deposited on a carrier of fibrous material.
