Another embodiment of the invention is shown in section in Fig. 3; again like features retain the same reference numbers. In this embodiment, the mouthpiece 3 may be made of a plastics material and comprise a passage 8 that extends internally through the mouthpiece 3 in a direction along the length of its axis. The passage extends from an open annular end 9 to an opening 10 formed in the mouth end 4. The passage 8 may accommodate a filter element 11 which may be a filter plug of cellulose acetate or paper.
The mouthpiece 3 may comprise internal ribs (not shown) which extend radially into the passage 8 to assist in gripping the filter element ii. The passage 8 follows the external profile of the mouthpiece 3 so that it narrows toward the opening lci in the io mouth end 4.
Another embodiment of the invention is shown in section in Fig. 4; again like features retain the same reference numbers. In this embodiment, the mouthpiece 3 is solid; that is, it does not comprise a passage as per the embodiment of Fig. 3. Instead it is homogenously formed from a suitable filter material such as cellulose acetate.
Another embodiment of the invention is shown in section in Fig. 5; again like features retain the same reference numbers. In this embodiment, the rod shaped portion 2 is a conventional cigarette 12 comprising a filter portion 13 at a filter end 14 and a cigarette body 15 that contains the tobacco. In this embodiment, the mouthpiece 3 is substantially as described with reference to Fig. 3; however, the acetate filter 11 is omitted from the mouthpiece and instead the annular end 9 of the mouthpiece 3 abuts the filter end 14 of the cigarette 12 and the tipping paper 7 extends into overlapping relation about the filter portion 13 and the cigarette body 15.
Another embodiment of the invention is shown in section in Fig. 6; again like features retain the same reference numbers. In this embodiment, the mouthpiece 3 is substantially as described with reference to Fig. 4; that is, the mouthpiece 3 is solid and preferably made from filter material such as cellulose acetate. In this embodiment, the rod shaped portion 2 is a paper rod 16 containing tobacco. Therefore the mouthpiece 3 also serves as a filter for the rod shaped portion 2.
Another embodiment of the invention is shown in Fig. 7; again like features retain the same reference numbers. In this embodiment, the mouthpiece 3 comprises two .. separately formed cellulose acetate filter elements: a first rod shaped element 17 which is solid, that is to say not hollow; and a second tubular element 18. The first and second elements 17, 18 are axially aligned to the rod shaped part 2 and attached thereto by an overlapping band of tipping paper 7, with the first filter element 17 disposed between the rod shaped part 2 and the tubular filter element 18. Optionally, a band of plug wrap 19 may be provided around the filter elements 17,18 to further support the assembly.
During manufacture of a tobacco industry product as shown in Fig. 7, the tubular filter element 18 is clamped and subjected to heat and pressure so that the mouthpiece 3 tapers from the rod shaped portion 2. In such embodiments the rod shaped portion 2 is a paper rod 16 containing tobacco.
With reference to any of the embodiments of Figs. I to 7, the mouthpiece 3 is placed in the mouth of an adult user during use, their lips forming a seal around the mouth end 4 so that they may draw air through the tobacco industry product 1 to entrain an aerosol produced by the rod shaped portion 2 of the tobacco industry product 1.
Again, with reference to any of the embodiments of Figs. 1 to 7, the mouthpiece 3 tapers so that the transverse cross sectional profile of the mouthpiece 3, that is to say the mouthpiece 3 when viewed end on to its longitudinal axis, changes from being circular where it extends from the rod shaped portion 2 to having a flattened profile at the mouth end 4, preferably an oval profile. This is more clearly seen in Fig. 8, which represents an embodiment generic to the embodiments described with reference to Figs. 1 to 7.
In another embodiment shown in Fig. 9, a tobacco industry product is provided comprising a stepped mouthpiece 20 in place of the tapered mouthpiece 3 of embodiments illustrated by Figs. 1 to 8. The step represents a step change in the transverse cross sectional profile from being substantially circular to being flattened. A
mouth end 21 of the mouthpiece 20 comprises the organoleptic substance 5.
A key characteristic of the flattened profile of the mouth end 4 of the mouthpiece 3,20 is that the transverse cross sectional profile of the mouth end 4 is defined relative to perpendicular major and minor axes A1, A2 (shown in Figs. 8 and 9) such that the profile is longer in a direction extending along the major axis Ai relative to a direction extending along the minor axis A2.

- 7 -Compared to a non-flattened profiled, an advantage of providing a mouth end 4 with a flattened profile is increased contact area with the user's lips when the mouth end 4 is placed in the user's mouth resulting in an increased effect of the organoleptic 5 and allowing less organoleptic substance 5 to be used, or to provide an increased user sensation or taste.
According to the invention the organoleptic substance 5 is arranged so as to contact the user's lips during use. With reference to the embodiments of Figs. 2 to 7, the organoleptic substance 5 is preferably applied to the tipping paper 7 used to attach the ./o mouthpiece 3 to the rod shaped part 2, the organoleptic substance 5 being applied to all, or a portion of, the tipping paper 7 corresponding to the mouth end 4 of the mouthpiece 3. The organoleptic substance 5 provides the user with a sensation or taste on their lips associated with the particular organoleptic used. In other embodiments, where tipping paper is omitted, the organoleptic substance 5 may be applied directly to an outer surface of the mouthpiece 3. Alternatively, the organoleptic substance 5 may be incorporated or otherwise impregnated into the mouthpiece 3 either during manufacture or subsequently thereto.
Also, by providing a mouth end 4 that is flattened in section, the tobacco industry product 1 is easier for a user to remove from a tobacco industry product pack.
Specifically, tobacco industry products are commonly arranged close-packed, with their longitudinal axes parallel, so that an array of ends of tobacco industry products is presented to a user from an open end of the pack. Arranging the mouthpieces 3 of the above described embodiments so as to be accessible from the open end of the pack allows the user to more easily grasp the flattened end of the mouthpiece 3 and remove the tobacco industry product.
According to the invention, the organoleptic substance 5 is preferably selected to provide a sensation from the list of sensations: cool, sweet, sour or hot.
In one embodiment of the invention the organoleptic substances is selected to provide a cool sensation provided by an artificial compound such as WS-3, WS-23 or Physcool.
In one embodiment of the invention the organoleptic substances is selected to provide a sweet sensation provided an artificial compound such a sodium salt of saccharine or thaumatin.

- 8 -In one embodiment of the invention the organoleptic substance 5 is selected to provide a sour sensation provided by, for example, citric acid. The citric acid may be naturally occurring or it may be synthesised.
In one embodiment of the invention the organoleptic substance 5 is selected to provide a hot sensation provided by, for example, nonivamide. The nonivamide may be naturally occurring or it may be synthesised.
With reference to the embodiments of Figs. 2 to 7, the organoleptic substance 5 may be applied to the tipping paper 7 prior to attaching the rod shape portion 2 to the mouthpiece 3.
Also according to the invention there is provided a method of manufacturing a tobacco industry product i comprising the mouthpiece 3 of any of the embodiments of Figs. ito 7; the method comprising providing an organoleptic substance 5 on or in the mouth end 4, 21 for contact with a user's lips.
In another embodiment, providing an organoleptic substance 5 on or in the mouth end 4,21 comprises applying or incorporating the organoleptic substance 5 into the tipping paper 7.
