  • the smoking article concerned is an alternative so-called "non- combustible" smoking article.
  • This type of smoking article does not appear to burn down as does a conventional smoking article, although a heat source within the smoking article does produce heat, which heat is used to produce a flavoured aerosol.
  • This reference is concerned with providing thermal indicators spaced along the length of the smoking article.
  • the thermal indicators comprise substances which cause a visible change at a pre-deter ined temperature and can be used to indicate, for example, which section of the smoking 2

  • EXAMPLE 2 The brand logo of a type of cigarettes was applied to the surface of a cigarette paper at intervals along the length of the paper using a thermochromic substance in the form of an ink. The thus modified cigarette paper was then used to produce both plain and filter-tipped cigarettes. The brand logos were not visible under normal handling temperatures of the cigarette, including manual handling of the cigarette by the consumer. However, when the cigarette was smoked the heat from the burning coal caused the thermochromic substance to change colour and each logo became successively visible along the length of the cigarette as the cigarette was smoked.
  • thermochromic substances in liquid form were applied to the surface of a cigarette paper.
  • the thermochromic substances were chosen such that each adjacent substance changed to a different colour upon heating. All of the thermochromic substances were colourless at normal handling temperatures of the cigarette paper. The thus 7

  • different colours successively appeared down the length of the cigarette.
  • EXAMPLE 4 A cardboard was produced comprising a thermochromic substance in the furnish thereof. The cardboard was used to produce a cigarette pack. When the cigarette pack was picked up by a consumer the thermochromic substance caused the pack to change colour in the region where the hand touched the pack.
  • thermochromic substance in the form of an ink was used to apply a marketing copy line to a conventional cigarette pack.

  • thermochromic substance was used to apply a brand logo to the surface of a conventional cigarette pack.
  • a second thermochromic ink was used to apply a marketing device to the same cigarette pack.
  • the first thermochromic substance was chosen such that it was visible under normal 8
  • thermochromic substance was chosen such that it was invisible at normal temperatures but became visible at body temperature, around 34-37°C, or above. Thus when the pack was at a normal temperature the brand logo was visible on the pack, but when the pack was held in the hand, or indirectly heated, the brand logo disappeared and the marketing device appeared.
  • thermochromic substance was applied to the carton, either when the carton was in the form of a blank or after construction.
  • the thermochromic substance was chosen such that it was not visible at the temperatures to which the carton may be subjected to during transport, storage or use, say up to 50°C, but became visible at unusually high temperatures. Use of such a carton would be useful as an anti-counterfeiting measure.
