Definitions

  • THE PRESENT INVENTION relates to a filter, and more particularly relates to a filter for use with a cigarette.
  • the present invention seeks to provide an improved filter.
  • a sheet of cigarette filter material adapted to be rolled , or to have a portion thereof rolled to form a cylindrical cigarette filter.
  • the sheet has one planar surface, and an opposed surface provided with parallel ridges.
  • the ridges are of 'saw-tooth' form.
  • the sheet has two opposed planar surfaces and is adapted to be rolled in a spiral manner.
  • one edge of the sheet is provided with a ridge.
  • the ridge is of filter material and the sheet has different properties to those of the ridge.
  • the sheet has a backing having one surface supporting a plurality of fibres that extend away from the backing.
  • the sheet may be made of fibrous material, or may be made of a porous material.
  • T e sheet may be provided with tear lines or lines of mechanical weakness dividing the sheet into a plurality of regions of predeterrnined shape and size.
  • the lines are orthogonal, lines in one direction being substantially evenly spaced apart, and in the transverse direction, comprising groups of line, the groups being spaced apart, and the lines in each group being relatively close to each other.
  • the sheet may be impregnated or provided with a flavouring.
  • the sheet is in combination with a pack of cigarette papers.
  • the invention also relates to a pack of cigarette papers having one edge of a sheet of filter material as described above claims secured thereto.
  • the invention also provides a method of rolling a cigarette comprising the steps of taking a sheet of filter material as described above, and rolling the sheet, or part of the sheet, to form a cylindrical filter, and incorporating the filter into a cigarette.
  • FIGURE 1 is a perspective view of a pack of cigarette rolling papers incorporating a filter material
  • FIGURE 2 is a perspective view, on an enlarged scale , of part of a filter material
  • FIGURE 3 is a perspective view of part of a filter made from the material of Figure 2,
  • FIGURE 4 is a view corresponding to Figure 2 showing an alternate form of filter material
  • FIGURE 5 is a view corresponding to Figure 3 showing a filter made from the material of Figure 4
  • FIGURE 6 is a view corresponding to Figure 2 showing a modified form of filter material
  • FIGURE 7 is a view corresponding to Figure 3 showing a filter made from the material of Figure 6.
  • FIGURE 8 is a view corresponding to Figure 2 showing another alternate form of filter material
  • FIGURE 9 is a view corresponding to Figure 3 showing a filter made from a material as shown in Figure 6, and
  • FIGURE 10 is a side view of a cigarette provided with a filter.
  • FIG. 1 a pack 1 of interleaved cigarette papers, of the type commonly used by persons who roll their own cigarettes is shown, the pack having a slot 2 from which a cigarette paper is emerging.
  • the sheet of filter material 4 is of rectangular form, and one edge 5 of the sheet is secured to the pack 1.
  • the sheet is provided with spaced apart fold line 6, which are spaced by a distance equal to the width of the pack 1 so that the sheet of filter material 4 can be folded or pleated to form a folded stack that will lie adjacent to, and be the same size as the pack 1, so that the combination of the pack 1 and the filter material 4, when folded, can be easily handled and stored, for example in a pocket or tobacco pouch.
  • the sheet of filter material 4 is divided into predetermined areas by transverse lines of weakness or tear lines 7, and axially extending lines of weakness or tear lines 8, 9, 10. The tear lines facilitate the tearing of the filter material into elements of a predetermined size and shape, selected to be ideal for use in fo ⁇ riing a cigarette filter when a cigarette is being rolled with a paper from the pack 1.
  • the lines 7 are spaced apart by a substantial distance, and may be used to provide elements of filter material 4 of desired width.
  • the orthogonally extending lines 8,9 and 10 are spaced from the edges of the sheet of filter material 4, but are close together, in a group of lines. Further groups of lines, equivalent to the lines 8,9 and 10 are provided, with the groups of lines being evenly spaced apart.
  • An appropriate combination of intersecting lines may be selected by a person preparing a filter for a rolled cigarette, so that the element torn from the sheet has a desired length.
  • the element of filter material that is torn from the sheet of filter material 4 is rolled to form a cylindrical filter that can easily be incorporated into a cigarette as the cigarette is rolled.
  • Figure 2 shows one example of a sheet of filter material 20 which may be attached to a pack 1 of the type described above.
  • the material 20 may be porous, and may thus be of a fibre material, or may be formed from porous cork or other material.
  • the lower surface 21 of the material is planar and the upper- surface is formed with a plurality of parallel ridges 22, 23.
  • the ridges are of 'saw tooth' form.
  • Figure 4 shows a sheet 30 of filter material, which again may be of a porous or fibrous nature, but the sheet 30 has planar upper and lower surfaces 31, 32.
  • a cylinder such as the cylinder 34 shown in Figure 5
  • a cylindrical filter is created with no open gas flow path.
  • Figure 6 shows a modification of the sheet 30 of Figure 4.
  • one edge of the sheet is provided with a ridge 35 which may be of semi-circular cross-section.
  • the presence of the ridge 35 facilitates rolling the sheet into a cylinder, as shown in Figure 7, with no open gas flow path.
  • the ridge 35 may comprise the filter material and the rest of the sheet 30 may be of lighter gauge, or even impervious to gas.
  • FIG 8 shows another filter material 40, which has a backing sheet 41, which may be an impervious sheet, carrying, on one surface, a plurality of upstanding fibres 42.
  • the structure thus resembles that of a carpet.
  • the filter material 40 is rolled to form a cylinder 43, as shown in Figure 9, the fibres extend radially inwardly, substantially closing any open gas flow path. The fibres provide a filtering effect.
  • a cylinder as shown in Figure 3, Figure 5, Figure 7 or Figure 9, may be used as a filter in a cigarette.
  • Figure 10 shows a cigarette 50 which incorporates a cylindrical filter 51, which is one of the cylinders as described above, and - tobacco 52.
  • the filter material may .be provided in different grades, exhibiting different degrees of filtering ability.
  • the thickness of the sheet of filter material, or the density of fibres, or the porosity of the filter material may be selected to provide filters ranging from a light gauge to a heavy gauge.
  • the filter material may be impregnated to provide a desired flavour, such as mint.
