Definitions

  • ABSTRACT A cigarette having a filter prepared by kneading a mixture of gluten and wheat flour with water, baking the kneaded mixture, and crushing the backed product into coarse grains of less than 60 mesh.
  • the present invention relates to a material used as an adsorbent for cigarettes or tobaccos (which will hereinafter be referred to as cigarette filter material).
  • cigarette filter material a material used as an adsorbent for cigarettes or tobaccos
  • the present invention relates to a cigarette filter material prepared from gluten and wheat flour.
  • the invention relates to a cigarette having a mouthpiece containing the cigarette filter material as an adsorbent as well as for cigarette holders or tobacco pipes in which the cigarette filter material is used as an adsorbent.
  • Cigarettes with filters have been in use for some time.
  • a cigarette with filter that is, a cigarette having a mouthpiece containing a filter or adsorbent material began to be commercially sold and since that time the demand for such cigarettes has been increasing gradually. This increase is partially caused by the announcement by medical or hygienical groups that smoking has some relation to the growth of lung cancer and that the adsorbing or filtering of nicotine and irritating matter by an adsorbent is in the general interest of smokers.
  • the present inventors have succeeded in making a cigarette filter material capable of providing a very suitable smoking taste which is fitted to the requirement of smokers and which has low resistance to permeability and a high adsorbability of tar.
  • Prior known cigarette filter materials which are employed are:( l) acetate fibers, (2) fibers rolled tubularly within a roll of paper, (3) a roll of piled crape papers, (4) a roll of piled pipe sheet, (5) a mouthpiece filled with cotton, (6) a roll of a laminate of thin cotton cloth and paper, (7) a layer of activated carbon, and (8) a mixture of activated carbon and acetate fibers or paper.
  • These materials are used along or in layers of a combination of two or three kinds of materials, or two or three layers of the aforementioned materials.
  • the inventors have discovered, during the investigation of various kinds of proteins, that they have a high adsorbability for gases. As the result of various studies, the inventors have succeeded in obtaining a cigarette filter material having both a high filtering efficiency and a very excellent smoking taste.
  • an object of the present invention is to provide an improved cigarette filter material which has a high filter efficiency for nicotine and other irritative matter in the smoke of cigarettes or tobaccos and at the same time providing an excellent smoking taste for the smoker.
  • Another object of this invention is to provide a cigarette having a mouthpiece containing the cigarette filter material.
  • a further object of the present invention is to provide a cigarette holder or a tobacco pipe having a filter portion containing the cigarette filter material.
  • the drawing is a device for testing the filter material of the present invention.
  • a cigarette filter material prepared by kneading gluten and wheat flour with water and then baking the kneaded mixture.
  • the cigarette filter material of the present invention when the cigarette filter material of the present invention was prepared by sufficiently kneading gluten and wheat in a mixing ratio of from 1 1.5 to 2 l with water and then baking the kneaded mixture, it showed an excellent adsorption rate for tar as shown above. Also, when the cigarette filter material was used as a filter or an adsorbent for cigarettes, it showed no resistance to the passage of smoke, the filter did not degrade the taste of the cigarette smoke, and it fit the requirement of smokers.
  • the filter material of the present invention may be effectively used as a filter for smoking pipes or a filter material for the mouthpiece of cigarettes.
  • the filter material may be used in smoking pipes or used as a filter material for the mouthpiece of cigarettes after it has been crushed into coarse grains of less than 60 mesh. Further, the cigarette filter material of the present invention may be used together with other filter materials.
  • EXAMPLE Lite by using the test device shown in the Figure. The results of the comparison are shown in the following table. In the test, a Japanese cigarette by the name of Ikoi" was employed.
  • a water tank is equipped with a control cock 2.
  • a rubber plug 3 is plugged in the opening of the tank 1 and a bent glass tube 4 is inserted in the plug until the end of the glass tube 4 opens into the tank.
  • the opposite end of the glass tube 4 is connectedto one end of a glass tube 7 by means of a rubber tube 5.
  • the other end of the glass tube 7 is connected, by means of a rubber tube 8, to a funnel 9 for holding a cigarette [0.
  • the inside diameter and the length of the glass tube 7 are 6 mm. and 35 mm., respectively.
  • a filter sample 6 is placed in the central portion of the glass tube 7. In operation, the smoke of the lit cigarette 10 is sucked into the tank 1 through the filter 6 by permitting the water in the tank 1 to flow out through the cock 2.
  • the opening of the cock 2 is so controlled that the volume of air sucked into the tank through the filter is 1,000 ml./ 3.5 min. This volume is required for proper burning of the cigarette.
  • a filter material for a cigarette consisting essentially of a kneaded and baked mixture of water, wheat flour and gluten and wherein said gluten and said wheat flour are present in a ratio of from 1:15 to 2:1 by weight.
  • a cigarette filter material as in claim 1 in which the baked mixture is crushed in the fonn of a coarse powder.
  • crushed baked mixture comprises coarse powder having a size of substantially smaller than 60 mesh.
