Definitions

  • This invention relates to a filter cigarette, comprising a tobacco 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 perforated or porous over at least a part of its area 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 NL-A-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 to 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 tobacco 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 tobacco 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 tobacco column and the filter.
  • the preferred material for layer 5 is 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.
  • the layer 5 comprised a tissue which is crimped to a large extent and the sealed ring had a width of about 2 mm.
  • the whole was surrounded with tip paper 8 with two lines of a suitable perforation 7 and by fastening a tobacco column of about 6 cm thereon, cigarettes were made with that filter.
  • the ventilation degree of these cigarettes that is to say the percentage of air, flowing from the sucking side which when through the perforations, appeared to be 60%.
  • After sealing the layer 5 to the connection with the tobacco column the average ventilation degree appeared to have descended very much.
  • the tar and nicotine outturn the following changes appeared to occur after sealing:
  • Other embodiments are also covered in the scope of the claims.
