  • the ends of the rod of tobacco and the filter material are axially joined by a sheet of overlapping tipping paper, which is wrapped around and adhered to the outside ot both the cigarette paper and the plug wrap to hold the cigarette together.
  • the tipping paper is perforated to provide vent channels between the filter material and the external air around the cigarette. Often, the vent channels are arranged in a ring around the circumference of the filter. When a smoker draws on the cigarette, external air enters the filter through the vent channels to dilute the smoke passing through the filter.
  • vent channels in tipping paper are formed by perforating the tipping paper using a series of pins during the paper manufacturing or cigarette assembly process.
  • Another known method is to create the vent channels by passing the tipping paper under a pulsing laser beam in the cigarette assembly machine. Both of these techniques require the use of expensive, specialised perforation equipment.
  • vent channels remaining unobstructed. If one or more of the vent channels is blocked, the level of ventilation is undesirably reduced.

  • the plug wrap may comprise a paper with a base weight of 25 gsm and a porosity of 3000 Coresta (CU). This allows external air entering through the tipping paper 400 to enter the filter material 210 and dilute the smoke, as is described in detail below.
  • the tipping paper 400 comprises a layer of embossed paper sheet configured to allow external air to enter the filter 200 through embossed sections of the tipping paper 400 during smoking.
  • the natural porosity of the tipping paper 400 may be very low such that it is substantially non-porous, for example one Coresta (1 CU), but is increased by embossing the paper 400 to open the paper's fibrous structure.
  • the tipping paper 400 may comprise an embossed TP595DW paper supplied by Tann Paper with a natural (unembossed) porosity of less than 2 CU. After being embossed, the porosity of the tipping paper 400 may be five hundred Coresta (500 CU) or higher.
  • the tipping paper 400 of this example is provided with an embossed pattern comprising embossed portions 410 spaced at short, regular intervals over substantially the entire external surface of the tipping paper 400.

  • the effect may be that a desired level of filter ventilation can be achieved without the need to form the conventional vent channels discussed above.
  • An example area of the embossed tipping paper 400 is shown in Figure 4, in which the tipping paper 400 is embossed with a pattern comprising a series of embossed portions 410.
  • Each of the embossed portions 410 may comprise small vent holes 411 in the tipping paper 400, which are formed automatically as the fibrous structure of the paper 400 is opened during the embossing process.
  • the individual size of the vent holes 41 1 may be significantly smaller than the conventional vent channels discussed above, for example one to ten microns (1 to ⁇ ).
  • the embossed pattern may comprise a plurality of equally spaced embossed portions 410, which are each approximately circular in shape with an outer diameter of approximately one thousand, eight hundred microns (1800 ⁇ ). It will be appreciated, however, that the embossed portions 410 may be of any suitable shape and size. The embossed portions 410 may each extend radially outwards from the generally smooth surface profile of the smoking article 100 to provide a textured surface at the exterior of the tipping paper 400.
  • each embossed portion 410 comprises eight substantially parallel ridges 412.
  • the centre of each of the ridges 412 is spaced from the centre of its neighbouring ridges 412 by a distance of approximately three hundred microns (300 ⁇ ).
  • the ridges 412 are of varying lengths and have their centre points aligned along a single axis so as to form an approximately circular embossed portion 410.

  • Each of the ridges 412 may comprise a plurality of the vent holes 41 1 referred to above. Additionally or alternatively, vent holes 41 1 may be located between the ridges 412 or at the periphery of the embossed portion 410. It will appreciated that the vent holes 41 1 represent the areas at which the highest rate of gaseous exchange through the tipping paper 400 can take place, and that their presence in the tipping paper 400 significantly increases the average porosity of the tipping paper 400 as a whole.
  • the embossed portions 410 are provided over a wide area of the tipping paper 400, rather than in a circumferential ring as is common for conventional vent channels.
  • the embossed pattern may comprise embossed portions 410 spaced at short, regular intervals over substantially the entire external surface of the tipping paper 400 on the filter 200.
  • the distance between adjacent embossed portions 410 may be of the same order of magnitude as that of the width or diameter of the embossed portions 410, or may be approximately equal to the width or diameter of the embossed portions 410 as in Figure 4.
  • the spread of embossed portions 410 over a large surface area of the filter 200 reduces the probability of a significant proportion of the available air passageway between the filter 200 and the external air being simultaneously obstructed during smoking of the cigarette 100.
  • This provides an advantage over conventional vent holes, which are confined to a small area of the tipping paper 400 (for example a circumferential ring) and therefore have a higher chance of being simultaneously obstructed.
  • the large number of small diameter vent holes 411 provided by embossing the tipping paper 400 may provide a more consistent percentage volume of external air in the gaseous flow
  • the ventilation provided by the embossed tipping paper 400 may be such that conventional vent channels are not required.
  • an embossed tipping paper 400 with an average porosity of 500 CU may provide a vent level of approximately 50% when a standard gaseous flow rate of 1.05 litres per minute is passing axially through the filter material 210. More specifically, when the cigarette 100 is lit and gas is flowing through the filter 200 from the tobacco rod 300 at a constant rate of 1.05 litres per minute towards the mouth end of the filter 200, 50% of the gas delivered to the mouth end of the filter 200 may consist of external air drawn into the filter 200 through the embossed tipping paper 400.
  • the vent level provided by the embossed tipping paper 400 may be substantially independent of the gaseous flow rate through the filter 200.
  • a 50% vent level may be observed at gaseous flow rates of 2.05 litres per minute and 3.1 litres per minute.
  • a lower or higher vent level can be achieved by respectively reducing or increasing the porosity of the embossed tipping paper 400.
  • One way in which this may be achieved is by reducing or increasing the pressure applied to the tipping paper 400 during the paper embossing process, as is discussed in more detail further below.
  • other techniques may also be used such as increasing or decreasing the size of the individual protrusions used to create the embossed pattern on the paper 400, or increasing or decreasing the surface area of the tipping paper 400 which is embossed.
  • Varying the porosity of the paper 400 by changing the surface area of the paper 400 to which the embossed pattern is applied is a potentially simpler technique than the other techniques discussed above because there will be no need to make significant adjustments to the embossing equipment.
  • the area of the paper 400 subjected to the embossing process can be adjusted whilst keeping the pressure settings and embossing rollers constant.
  • tipping papers 400 configured to provide vent levels of anything between 1 and approximately 60% may be produced by varying the embossing pressure.
  • Tipping papers 400 configured to produce vent levels of 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45% and 50% may all be included within this range.
  • the tipping paper 400 may be glued around the circumferential surface of the plug wrap 220 and the circumferential surface of an abutting end of the rod 300 using circumferential stripes of adhesive PVA material to secure the two together.
  • the adhesive material between the plug wrap 220 and the tipping paper 400 may be confined to single narrow stripe proximate the mouth end of the filter 200.
  • additional stripes of adhesive between the plugwrap 220 and the tipping paper 400 may be provided to deliberately obstruct some of the embossed portions 410 to reduce the vent level.

  • a tipping paper 400 comprising both embossed portions 410 and a ring of conventional vent channels may provide a vent level of 80% or 90%.
  • the tipping paper 400 may be pre-printed with a pattern.
