Description

  

  Tampon     filtrant    pour la fumée du tabac.    On connaît déjà de nombreux filtres pour  la fumée du tabac, qui revêtent. la forme de       tampon    placé à. une des extrémités d'une ci  garette ou     d'ttn    cigare, ou sur le passage de la  fumée dans le conduit d'une pipe, d'un     fume-          eig-are    ou d'un fume-cigarette.  



  Ces filtres sont en général constitués par       une-    matière fibreuse d'origine organique  (ouate de coton, papier, papier crêpe). Quel  quefois, ils sont en une matière inorganique,   < lui ne revêt pas la forme fibreuse, mais celle  d'un solide spongieux (cartouche en terre  cuite poreuse) ou d'une masse granuleuse  (grains de charbon).  



  On a fait la constatation que les fibres de  verre inorganique, qui peuvent être extrême  ment ténues, retiennent très efficacement     les.     constituants nocifs de la fumée du tabac (ni  eotine, goudrons).  



  La présente invention a pour objet un  tampon filtrant pour la fumée du tabac, cons  titué au moins en     partie    par une matière     fi-          1)i    ruse. Ce tampon est caractérisé en ce qu'une  partie au moins des fibres de cette matière  sont en verre inorganique.  



  La matière fibreuse du tampon peut, par  exemple, né présenter que des fibres en  verre inorganique. Elle peut aussi être un  mélange intime de fibres de cellulose et de  fibres de verre inorganique. Dans ce dernier  cas, elle sera, par exemple, obtenue à partir    d'une pâte renfermant. en mélange intime de  la, pâte à papier et des fibres de verre inorga  nique. La proportion entre fibres de cellulose  et fibres de verre peut. varier dans de     grandes     limites.  



  On a constaté qu'un tampon renfermant  les deux genres de fibres: verre et cellulose,  est plus efficace qu'un tampon ne comportant  que des fibres de cellulose, en ce qui concerne  son pouvoir de rétention des constituants no  cifs de la fumée du tabac.



  Filter pad for tobacco smoke. Many filters are already known for tobacco smoke, which coat. the form of buffer placed at. one end of a ci garette or cigar, or on the passage of smoke in the duct of a pipe, a cigarette holder or a cigarette holder.



  These filters are generally made of a fibrous material of organic origin (cotton wadding, paper, crepe paper). Sometimes they are in an inorganic material, <it does not take the fibrous form, but that of a spongy solid (porous terracotta cartridge) or of a granular mass (grains of coal).



  It has been found that inorganic glass fibers, which can be extremely thin, retain them very effectively. harmful constituents of tobacco smoke (neither eotin, tar).



  The present invention relates to a filter pad for tobacco smoke, consisting at least in part of a cunning fine material. This pad is characterized in that at least part of the fibers of this material are made of inorganic glass.



  The fibrous material of the tampon may, for example, only consist of inorganic glass fibers. It can also be an intimate mixture of cellulose fibers and inorganic glass fibers. In the latter case, it will, for example, be obtained from a containing paste. as an intimate mixture of paper pulp and inorganic glass fibers. The proportion between cellulose fibers and glass fibers can. vary within wide limits.



  It has been found that a tampon containing the two kinds of fibers: glass and cellulose, is more effective than a tampon comprising only cellulose fibers, as regards its capacity to retain the harmful constituents of tobacco smoke. .
