Definitions

• Figure 4 shows an enlarged side elevation view of the first embodiment of the invention in a second state
• Figure 5 shows a perspective view of a part of a second embodiment of the invention in a first state
• the transparent first covering layer section 16 allows viewing of the additive release components 15 around the first filter section 12.
• the first covering layer section 16 is transparent over the whole circumference, or is transparent over only a part of the circumference.
• the covering layer comprises a transparent inner layer, which is formed of a transparent sheet of cellulose acetate.
• the transparent inner layer is surrounded by the outer covering layer, which is paper.
• a window i.e. aperture is formed in the outer covering layer, which is covered by the transparent inner layer.
• Figure 2 shows a perspective view of the smoking article 10, in which a part of the second filter section 13 has been cut away and showing the homogenous filtration material of the second filter section 13.
• the exterior surface of the first filter section 12 is also visible.
• the cylindrical first filter section 12 has a smaller diameter than the adjacent filter sections 13,14, such that the additive release components 15 on the periphery of the first filter section 12 are substantially within the diameter of the second and third filter sections 13,14, and within the covering layer.
• the Filtrona hardness can be determined as follows: a filter rod (for example a length of 102 millimetres) having a mean diameter (D), of about 7.8 millimetres, is compressed between two plates provided in the testing instrument. The rod is subjected to compression for 15 seconds by a load of 300 grams applied to opposite sides of the cylindrical surface of the rod and the average depression (A), that is the decrease in diameter of the rod is measured.
• the third filter section 14' is the same length as a second filter section 13, or the third filter section 14' is longer, e.g. twice as long, as a second filter section 13.
• the filter unit 40 comprises more than two first filter sections 12.
• the filter unit 40 comprises a plurality of first filter sections 12, each separated by a co-axial filter section which forms the second filter section or third filter section.
• the grooves 59a have been shown as extending parallel to a longitudinal access of the filter 50. Alternatively, one or more grooves extend helically or circumferentially and wholly or partly around the first filter section 52 or in any other configuration.
• a covering layer 76 surrounds the first filter section 72, additive release components 75 and the transparent sheets 78.
• the covering layer is formed of an air and fluid impermeable material, as described in any of the embodiments.
• the covering layer 76 is provided with one or more apertures aligned with the transparent sheets 78.
• the transparent sheets 78 are affixed to the covering layer 76, to close the apertures 77 and allow viewing of the additive release components 75.
• the additive release components are located adjacent a periphery of the filter 80, to which the covering layer 76 is directly affixed, without forming a chamber for the additive release components.
• the additive release component are located in a filter, within filtration material. Alternatively, the additive release component are located in a tobacco rod.
• the terms "flavour” and “flavourant” refer to materials which, where local regulations permit, may be used to create a desired taste or aroma in a product for adult consumers. They may include extracts (e.g., licorice, hydrangea, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, menthol, Japanese mint, aniseed, cinnamon, herb, wintergreen, cherry, berry, peach, apple, Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamon, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, piment, ginger, anise, coriander, coffee, or a mint oil from any species of the genus Mentha),
