Definitions

  • the present invention relates to a wrapping paper for a non-combustion heating-type smoking article, a non-combustion heating-type smoking article, and an electric heating-type smoking system.
  • Non-combustion heating-type smoking articles of a type in which heating is performed from around a tobacco rod including shredded tobacco to deliver volatile components to a user are known.
  • a tobacco rod wrapped by a wrapping paper is heated, but the tobacco rod is left unburned after use (after heating) unlike conventional cigarettes.
  • white (colorless) paper while having a logo or the like in some cases, is commonly used as a wrapping paper for wrapping shredded tobacco.
  • the present inventors focused on using a wrapping paper having a colored part having a discolored region in a specific range after heating to make the unpleasant discoloration less noticeable.
  • Paper made mostly from pulp will be scorched and discolored brown if heated at or above a certain temperature. Such discoloration cannot be easily prevented because it is caused for a physical reason due to thermal decomposition of pulp and components of the paper.
  • the present inventors have found that discoloration, if caused by scorching, can be made less easily recognizable as an unpleasant scorch color if the degree of discoloration from the color of the original paper is low in a certain range.
  • the present inventors have found that the problem of unpleasant discoloration described above can be solved by using a paper having a region where the color difference before and after heating is small.
  • the present inventors have discovered that such a region where the color difference is at a visually acceptable level can be expressed by a mathematical formula, and found that by using, as a wrapping paper, a paper having a colored part that exhibits a specific numerical value when values of L*, a*, and b* before and after heating are substituted in the mathematical formula, the problem of unpleasant discoloration peculiar to non-combustion heating-type smoking articles can be solved.
  • the problem to be solved by the present invention is peculiar to non-combustion heating-type smoking articles heated with electric heating-type devices, and is a problem that has not arisen in conventional smoking articles (e.g., cigarettes).
  • a wrapping paper for a non-combustion heating-type smoking article which wrapping paper does not cause appearance-related unpleasantness that may be caused by heating, can be provided.

  • the pre-heating L* value of the colored part may be 90 or less.
  • the values of L*, a*, and b* before and after heating are each a simple average of values measured at five points in a colored part of a sample paper.

This operation was performed quickly (within 3 seconds) to minimize the decrease of the temperature in the muffle furnace. Under the heating conditions in this example (preset muffle furnace temperature: 230°C, paper sample heating time: 3 minutes), the actual temperature of the paper reached about 230°C, which was the same as the preset muffle furnace temperature, in 1 minute at the latest after the door was closed.

  • L* is an axis representing lightness
  • a* is an axis representing blue to yellow
  • Paper samples before and after heating were shown to 20 panelists one by one, and unsightliness they received from the color tone of the samples was inquired.
  • the appearance impression of the sample was evaluated as ⁇ , and when the number was less than 11, the appearance impression of the sample was evaluated as O. The results thereof were used for analysis.
  • Formula (1) means that the appearance impression after heating is almost determined by ⁇ L*a*b*, which is a color difference between a paper sample before heating and a paper sample after heating. For example, as the value of ⁇ L* decreases and the values of ⁇ a* and ⁇ b* increases, the discriminant score increases, which means that the post-heating impression of the paper is located in a worse direction.

  • Samples that gave bad appearance impressions in the evaluation are indicated by " ⁇ " and located at points where values of ⁇ a* and ⁇ b* are both large. This means that upon heating, the color has greatly changed toward red-violet, yellow, or a combination thereof, that is, brown, and many of these samples have relatively small ⁇ L* values. That is, these samples are samples that visually come closer to what is called a pale scorch color to a deep scorch color, and it can be intuitively understood that these samples give bad appearance impressions.
  • samples of " O" that gave good appearance impressions are located at points where values of ⁇ a* and ⁇ b* are both small. This means that upon heating, the color has greatly changed toward blue, green, or a combination thereof, that is, blue-green. Some are evaluated as O despite having relatively low ⁇ L* values, that is, having low lightness and being dark. Many of these samples, in contrast to the samples of ⁇ , have relatively small L* values before heating and large a* and b* values, that is, are dark and have high saturation. Such a sample having a deep hue is less likely to undergo a noticeable change upon heating, which leads to a good appearance impression.
  • the degree of change in color of a paper before and after heating was focused, and its region was quantified to define an effective range.
