- the predetermined region may be formed to direct additive towards the side of the filter.
- the additive for example additive comprising a colourant, may reach the periphery of the filter so that a visual indication is provided to the user that the additive has been released.
- Figure 1 shows a tape 1 having a plurality of additive-containing members in the form of sealed pockets 2 spaced along its length. Each pocket 2 has an inner space containing an additive.
- the tape and pockets may be formed from a flexible polymeric material such as Polyvinyl alcohol (PVOH) or polyethylene (PE).
- a cut section 1a of the tape 1 may be positioned within the cellulose acetate plug of the filter 3 of a cigarette 4.
- the smoker can cause the pocket 2 to rupture so as to release its additive. In this way, the smoker may cause the smoke drawn from the cigarette 4 to be selectively flavoured.
- the tape 1 is provided with a weakened corner region 5 at one end of the pocket 2.
- the pocket breaks in weakened corner region 5 when pressure is applied to the outside of the filter 3.
- the pocket 2 includes a smoke modifying agent (e.g. water, triacetin, or a flavourant) and the weakened corner region 5 is configured to direct the smoke modifying agent towards the tobacco rod of the cigarette 4.
- a smoke modifying agent e.g. water, triacetin, or a flavourant
- the weakened corner region 5 is configured to direct the smoke modifying agent towards the tobacco rod of the cigarette 4.
- This is particularly advantageous in filters in which smoke flow is slower nearer the tobacco end than nearer the mouth end, which may for example be the case if ventilation holes are provided near the mouth end. In this case directing smoke modifying agent towards the mouth end provides increased interaction time between the smoke modifying agent and the smoke.
- each pocket 2 is provided with a weakened corner region 5 on the mouth end region of the pocket rather than on the tobacco end region.
- a smoke modifier in the form of a flavourant is contained in the pocket 2.
- the pocket 2 of Figure 4 is configured to direct flavourant towards the mouth end of the cigarette 4. This results in the flavourant being released near the mouth end for maximum flavour.
- a horizontal or vertical form, fill, seal method may be used to manufacture the tape 1.
- the tape 1 may be formed from two or more polymeric layers which are sealed together such that the non-sealed areas form the pockets 2.
- Heat-sealing, ultrasonic sealing, water bonding or any other suitable process may be used to form the seals.
- the weakened corner regions 5 of the tape 1 may be formed in a modified vertical form, fill, seal method.
- the seal step in particular may be modified to provide the pocket 2 with a transverse edge which makes an acute angle with the longitudinal axis of the filter 3, thereby to provide a weakened corner region 5.
- Figure 5 illustrates a method of manufacturing the tape 1.
- cavities 7 are formed in a first layer 6. This forming may involve causing the first layer 6 to adopt to the shape of a mould (not shown) which is under vacuum.
- the cavities 7 protrude from one side (e.g. the lower side) of the layer 6.
- the cavities 7 are shaped such that they have a transverse edge which makes an acute angle with the longitudinal axis of the first layer 6.
- the cavities 7 are filled with additive 8.
- a second layer 9 is positioned on the first layer 6 on the opposite side (e.g. the upper side) from the side from which the cavities 7 protrude.
- the layers 6, 9 are sealed to each other, e.g. using heat sealing.
- a sealed area 10 is formed around each of the cavities 7, thus forming the pockets 2 in the tape 1.
- the cavities may be regularly shaped, e.g. with transverse edges that are perpendicular to the longitudinal axis of the first layer.
- the part of the sealed area between the pockets may be provided with a transverse edge which makes an acute angle with the longitudinal axis of the tape.
- tapes having a weakened sealing region may also be manufactured using a similar method.
- unsealed areas may be provided between the pockets such that there is a narrower sealed area at a transverse edge of each pocket than there is at the longitudinal edges of each pocket.
- the layers of the tape come apart in this narrower sealed area and the pocket ruptures.
- a sealed area at a longitudinal edge of each pocket may be made sufficiently narrow that the layers of the tape come apart in this area.
- a sealed area may be made weaker by including therein one or more unsealed areas.
- a sealed area may include a narrow unsealed area ("line") passing therethrough in a direction perpendicular to the edge of the pocket.
- the line is sufficiently narrow that the additive cannot pass therethrough but makes it easier for the layers of the tape to come apart.
- the strength of the seal could also be controlled by varying, for example, the temperature of the sealing unit.
- the tape 1 may be wound onto a reel and then drawn from the reel into a flow of filter tow passing through a filter rod maker, so as to be incorporated into an elongate filter rod.
- the cutter of the filter maker then cuts the elongate filter rod into segments to form individual filter rods, each containing one or more pockets 2.
- This filter manufacturing process is substantially similar to that described in WO2010/003899 , but with the elongate capsule-containing tube of WO2010/003899 replaced by the tape 1.
- the methods described above facilitate the positioning of the pocket 2 and its weakened region 5 in the filter 3.
- a part of the tape 1 along a longitudinal edge of the tape 1 may be folded back and sealed to the tape 1. This can have the effect of reducing the longitudinal tensile stretch and increasing the longitudinal tensile strength of the tape 1. This in turn can facilitate the handling of the tape 1 during manufacture, for example when the tape 1 is wound onto and subsequently drawn from the reel.
- FIG. 6a shows a further example of a section 11a of tape 11 positioned within the cellulose acetate plug of the filter 13 of a cigarette 14.
- the section 11a includes a first fluid-containing pocket 12a and a second fluid-containing pocket 12b.
- the pair of pockets 12a, 12b have the same longitudinal disposition along the tape 11.
- the pockets 12a, 12b are positioned so that applying squeezing finger-pressure to the outside of the filter causes both pockets 12a, 12b to break simultaneously so as to simultaneously release both fluid additives.
- Weakened regions (not shown) in each of the pockets may direct the smoke modifying agent towards the tobacco rod and/or the mouth end of the cigarette, wherein the direction may depend upon the type of additive as described above.
- the tape 11 may be manufactured and included in the filter 13 using similar methods to those described above.

- the un-sealed body is then filled with the additive 22. This may involve holding the un-sealed body vertically with its open end facing upwards.
- the un-sealed body is then sealed by distorting and then joining together walls sections of the tubular section 21a, thereby forming the second end section 21c.
- the wall sections may be joined together by heat sealing, ultrasonic welding, water bonding or any other suitable process.
- the additive release component 20 is adapted to contain the additive 22 until such time as it is released by the smoker.
- the component 20 is adapted to rupture in the second end section 21c.

- the component 20 can be aligned with the longitudinal axis of the filter and can have weakened regions at either end so that the additive 22 is released towards either the tobacco end or the mouth end of the filter.
