Definitions

  • This invention relates to a filter cigarette, comprising a tabacco column, wrapped up in cigarette paper, and a filter, which filter comprises cellulose acetate or other suitable material surrounded by a layer which is impermeable to air, such as filter wrapping paper, and surrounded by tip paper which is entirely or partly perforated or porous and which is extending over the filter wrapping paper and an end portion of the cigarette paper.
  • a filter for such a cigarette is known from Dutch patent application 80 01948.
  • This known filter has filter wrapping paper which is impermeable to air in which slots are pressed in more or less regular distances around the outer periphery, which slots also locally compress the cellulose acetate.
  • the tip paper of the known filter is porous or is provided with perforations and none of the slots is extending over the entire length of the filter, only air would reach the mouth of the smoker through that slots when smoking a cigarette provided therewith. So the smoke would be diluted with ventilation air as it were, and that would have advantageous influence on the tar and nicotine supply of the cigarette.
  • the invention aims at improve the situation as described above.
  • the material with the open structure can be a non-woven or a tissue of which the warp and weft preferably have different crimp. In the latter case the warp threads with a stronger crimp than the weft threads extend preferably in the direction of the longitudinal axis of the cigarette.
  • the cigarette shown in the drawing comprises a tabacco column surrounded by cigarette paper 1 and a filter 2.
  • the filter with a length of approximately 25 mm comprises in radial direction from the inside to the outside a bar of cellulose acetate 3 surrounded by filter wrapping paper 4 impermeable to air.
  • a layer 5 made of a material with an open structure is wrapped around this filter wrapping paper of which a ring 6 is sealed which . is adjacent to the tabacco column.
  • the layer impermeable to air 4 can also be obtained by sealing one of the surfaces of the layer 5 with open structure.
  • the outer periphery of the filter comprises a tip paper 8 provided with perforations 7 which is also connected to part of the cigarette paper 1 in order to achieve a connection between the tabacco column and the filter.
  • layer 5 is thought of a kind of gauze, but a non-woven material can be preferred as the visible end of the filter does not have an appearance which differs from the appearance of a normal filter cigarette.
