Definitions

  • This invention relates to filters for cigarettes, cigars or cheroots.
  • One object of the invention is to provide an efiicient filter which can be easily and cheaply produced.
  • Another object of the invention is to provide an efficient filter which can be readily incorporated in the article to be smoked.
  • a further object of the invention is to provide a filter which in addition to absorbing moisture contained in the smoke and products of combustion will also absorb the harmful tarry constituents of tobacco, preventing these from passing into the smokers mouth.
  • a still further object of the invention is to provide a method for readily producing the improved filter.
  • Figure 1 illustrates a cigarette having fitted in one end thereof a filter made according to the invention, the paper tube of the cigarette being broken away at the filter end to show the filter.
  • FIG. 2 shows the filter separately in longitudinal central section
  • FIG. 3 illustrates one method of producing filters according to the invention.
  • the filter shown in Figures 1 and 2 comprises three parts, namely, two discs a, a of viscose sponge, between which is disposed a disc or wad c of absorbent cotton, these three parts being contained in a paper tube f, which, with the filter parts contained therein, is disposed at the end of a cigarette d so as to form an extension of the tobacco b.
  • Filters such as shown in Figures 1 and 2 may be made in the manner shown in Figure 3, in which f is a paper tube having alternately disposed therein wads or pieces a of viscose sponge and wads or pieces of absorbent cotton 0.
  • the viscose sponge pieces a are of twice the length required for the filter, so that a corresponding number of filters can be cut from the rod shown in Figure 3 by cutting along the transverse lines e.
  • foam rubber may be used, or one of these parts may be made of foam rubber and the other part of viscose sponge. Both materials act satisfactorily to absorb moisture in tobacco smoke and the products of combustion of the tobacco and, in the case of cigarettes, of the enclosing paper, and thereby improve the taste of the smoked article; they do not themselves harmfully afiect the taste, and they have the further advantage that they can be readily cut by rotating cutters.
  • I may also use folded or coiled sheets.
  • the above materials may be used alone, but it is of advantage to include in the filter a wad of the like 0 of absorbent cotton which absorbs, in particular, the tarry constituents of the tobacco.
  • the placing of the cotton wad between the other two filter parts prevents fibres from the cotton reaching the lips or tongue of the smoker and also maintains the original length or thickness of the wad, and prevents contact between tht cotton fibres and the tobacco.
  • the prefabricated cigarette filters made according to the invention can be readily introduced into the cigarette rod of ordinary cigarette making machines for incorporation in the cigarettes produced by such machines, and the filters themselves can be readily produced in the manner described in connection with Figure 3.
  • a filter for cigarettes, cigars or cheroots comprising two parts made of viscose sponge and a third part made of absorbent cotton, the said cotton part being disposed between the two parts made of viscose sponge.
  • a filter for cigarettes, cigars or cheroots comprising a cylindrical casing, two parts made of viscose sponge and a third part made of absorbent cotton, all said parts being disposed in and retained by said cylindrical casing, and said cotton part being disposed between the two parts made of viscose sponge.
