Definitions
- This invention relates to a tipping assembly for an elongate smoking article, such as a cigarette.
- a tipping assembly for an elongate smoking article, the assembly comprising an open-ended tube provided with a plurality of apertures spaced round the circumference of the tube, thereby dividing the tube into two sections and providing communication between the inside and outside of the tube, and a tipping wrapper surrounding the tube, characterised in that said portion of the tipping wrapper overlying the apertures is adapted to permit gas flow both through the apertures and said portion and to offer greater resistance to the gas flow than is provided by the apertures alone
- the tipping assembly 100 comprises an open-ended polyethylene tube 30, 25 mm in length, wrapped in tipping paper 20 by means of which the tube 30 is attached to the tobacco rod 10.
- the polyethylene tube 30 is provided with four apertures or slots 60 each 3 mm long and 1 mm wide and extending through the wall of the tube 30. The longer axis of each slot 60 is parallel to the longitudinal axis of the tube 30.
- the slots 60 are equidistantly spaced round the circumference of the tube 30 about half-way along the tube.
- the tipping paper 20 is provided with a circumferential series of perforations 70 overlying the slots 60.
- the perforations 70 are of 0.80 mm diameter or less.
- FIG. 3 and 4 there is shown a second embodiment comprising a tobacco rod and tipping assembly similar to that shown in Figures 1 and 2, identical features retaining the same numbering, and further provided with a sheet 50 of porous plug wrap material (of porosity 850-1600 Filtrona K units) between the tube 30 and the perforated tipping paper 20 and a 5 mm plug 40 of acetate filter material at the mouth end of the tube.
- the tube is 20 mm in length, making an overall tube and plug length of -25 mm.
- cigarettes provided with tipping assemblies according to the embodiments of Figures 1/2 and 3/4 were prepared and compared with a conventional filter cigarette (the control) using standard methods of analysis on a smoking machine and were also subjectively assessed by a smoking panel.
- the tipping wrapper of each of the cigarettes of the invention was perforated with four holes, one hole above each slot in the tube.
- the four holes were each about 0.8 mm diameter and 0.75 mm diameter for the embodiments of Figures 1/2 and 3/4 respectively.
- FIG. 5 there is shown a third embodiment of the invention comprising a cylindrical tobacco rod 110 enwrapped in cigarette paper 115, and a tipping assembly indicated generally at 1000.
- the tipping assembly comprises a cellulose acetate filter rod 200 of conventional construction and in abutment therewith an open-ended polyethylene tube 130 wrapped in tipping paper 120 by means of which the tube and filter rod are attached to the tobacco rod.
- the tube 130 is divided into two tubular sections 131 and 132 by three apertures 160 extending round the circumference of the tube 130 and separated by three narrow integral webs 161 of the material of the tubing which hold the two sections 131,132 in a fixed relationship apart from each other.
- the tipping paper 120 is provided with a circumferential series of perforations 170 overlying the apertures 160.
- the perforations 170 are 0.8 mm diameter or less, considerably smaller than the width of the apertures 160, which is about 2 mm.
- FIG. 7,8 and 1 0 there is shown a fourth embodiment comprising a tobacco rod and tipping assembly similar to that of Figures 5,6 and 9, identical features retaining the same numbering, and further provided with a plug 140 of cellulose acetate filter material at the mouth end of the tube.
- the tube 130 is substantially shorter than the tube of Figures 5 and 6.
- FIG. 10 and 11 there is shown a fifth embodiment similar to that of Figures 5 and 6 except that the separated sections 131,132 of the tube 130 are held in a fixed relationship to each other not by integral webs but by rectangular vanes 180 of polyethylene extending longitudinally within the tube 130 from one section to the other and radially outwards from the longitudinal axis of thetube to a distance at least equal to the internal radius of the tube.
- any of the third, fourth, and fifth embodiments may be modified by the incorporation of a sheet of porous plug wrap material (of typical porosity 200-1600 Filtrona K units) between the tube and the tipping paper.
- the tube 130 may be divided into its sections 131, 132 by a number of apertures 160 other than three together with the respective number of webs 161 in order to suit specific smoking requirements.
- the tube may be filled partly or wholly with highly porous material such as cellulose acetate in the sections 131 or 132.
- the filter rod 200 may at least in part occupy section 131.
- the tipping assembly of the invention shows that it is possible to achieve low tar yields with high nicotine, low carbon monoxide, and acceptable smoking panel ratings, compared with conventional filters which utilise high levels both of filtration and dilution.
- Perforations in the tipping wrapper may be provided by a large number of .small perforations or by a small number of relatively large perforations.
- the tipping wrapper may alternatively be adapted to permit gas flow through the apertures in the tube by providing a tipping wrapper having a very high porosity rather than by providing perforations.
- the tube may be made of impervious material other than polyethylene, such as cardboard.
