Definitions

  • the present invention relates to the filters provided for the cigarettes in order to prevent the harmful substances contained in tobacco, from reaching the respiratory tract.
  • the cigarette smoke contains up to five hundred substances which are detrimental for the human health, in the form of a suspension; and said substances are inhaled and entrained with the smoke, to the respiratory system of the smoker.
  • these harmful substances are, for instance, tar and the derivatives thereof, sulphur, various radio-active substances, and the like.
  • the irritant effects of said substances lead to various pulmonary diseases, particularly to fatal health problems such as bronchial cancer generally known as the lung cancer and chronic obstructive pulmonary disease (COPD).
  • COPD chronic obstructive pulmonary disease
  • cigarettes are provided with filter-tips that adsorb said harmful substances, so that at least a part of these substances will be prevented from reaching the respiratory tract.
  • All of the filters that are used for this purpose employ the mechanical filtration techniques.
  • the particles of harmful substances are trapped on various fibrous or porous substances, mainly cellulose, while the cigarette smoke passes between the narrow spaces between the fibres or pores.
  • Said shank joint comprises a metallic and generally aluminium tube that connects the parts.
  • the tobacco smoke which comes into contact at a high temperature, with said metal, condenses when it contacts with said cold metal surface and leaves an important portion of the harmful substances it contains, on this metal tube.
  • the tar or paste formed by the accumulation of the harmful substances on this metal part, has to be removed and wiped off.
  • the object of the present invention is to realize a filter that prevents the harmful, toxic substances present in the cigarette, from reaching the respiratory tract of the smoker.
  • Figure la is the cross-sectional view of the cigarette filter with spherical absorbing surfaces
  • Figure lb is the cross-sectional view of the cigarette filter with absorbing surfaces in the form of stripes.
  • the cigarette filter (1) according to the present invention comprises adsorbing surfaces (2), placed in a conventional cigarette filter element (1), whereby the warm cigarette smoke will get cooler and condense when it comes into contact with said surfaces, which form a base (substrate) for the harmful substances laden in said smoke.
  • physical filtration is provided by means of the cigarette filter (1) according to the present invention.
  • the adsorbing surfaces (2) placed in the cigarette filter (1) are preferably spherical metal particles with a diameter within a range of 0.5-1 mm ( Figure la).
  • the reason for preferring a spherical form as a geometrical shape is that the spheres have larger surface areas.
  • adsorbing surfaces (2) are used as the material of said adsorbing surfaces (2).
  • Said adsorbing surfaces (2) are placed homogeneously into the filter (1).
  • the metal particles used as adsorbing surfaces may be such structures as spheres, cubes, rectangular prisms, etc., as well as in the form of stripes placed along the filter (Fig. lb).
  • said adsorbing surfaces (2) change colour due to macroscopic modification.

Abstract

Les surfaces adsorbantes (2) du filtre de cigarette (1) décrit dans l'invention forment une surface refroidissant la fumée encore chaude, laquelle, parvenant au contact de surfaces (2) plus froides, se refroidit brusquement. Dès lors, les substances toxiques de la fumée forment une suspension, se lient aux surfaces adsorbantes (2), y restent emprisonnées, et ne pénètrent pas dans les voies respiratoires.
