Description

   Roll paper for non-combustion heating type smoking articles, non-combustion heating type smoking articles and electric heating type smoking system   

The present invention relates to roll paper for non-combustion heating type smoking articles, non-combustion heating type smoking articles and electric heating type smoking systems.

Non-burning heated smoking articles in the form of heating from the periphery of a tobacco rod containing tobacco shreds to deliver volatile components to the user are known. In non-combustion heating type smoking articles, tobacco rods wrapped with rolled paper are heated. However, unlike conventional cigarettes, the tobacco rods remain unburned after use (after heating).

In the conventional cigarettes, white (colorless) paper is generally used as a roll paper for wrapping tobacco shreds, although there are cases in which a trademark is added.

In a non-combustion heating type smoking article, when a conventional paper used for cigarettes is used as a rolled paper for wrapping tobacco shreds, discoloration may be uncomfortable for the user due to heating during use.

Accordingly, the present invention has as its object to provide a roll paper for a non-combustion heating type smoking article which does not cause a discomfort in appearance due to heating.

In order to solve the above problems, the present inventors focused on using a roll paper having a portion having a certain color difference ΔE * or more after heating to make the uncomfortable discoloration less noticeable.

When paper with pulp as the main material is heated at a certain temperature or more, it will be coked and change color to brown. Because this reason is a physical phenomenon caused by the thermal decomposition of pulp or paper constituents, it cannot be simply prevented. This discoloration. However, even if the discoloration caused by coking occurs, in order to prevent the discoloration from being recognized as an uncomfortable color, it was found that a specific heat-sensitive material can be added to the roll paper in advance to cause a color difference of more than a certain value before and after heating. Makes discomfort discoloration less noticeable.

    [Example]    

Hereinafter, the present invention will be described more specifically with reference to the examples. However, the present invention is not limited to the description of the following examples without departing from the gist.

<Preparation of Paper Samples>

A commercially available rolled paper for tobacco rods was cut into 5 cm × 5 cm pieces.

In addition, the heat-sensitive material was selected from the substances shown in Table 1 below, and an aqueous solution of each substance was prepared at the concentrations shown in Table 1. Each aqueous solution was applied to the cut roll paper in a width of 3 cm using a pen.

In addition, a person who did not apply the cut roll paper at all was used as a control group. The content of citric acid (which is described in Table 1 as a coating amount but not applied) in a commercially available tobacco rod roll paper is about 1.2% by weight based on the entire amount of the roll paper.

A commercially available self-extinguishing tobacco roll paper (coated with a self-extinguishing agent on the surface in contact with tobacco shreds) was prepared as Comparative Example 1.

Each sample was placed on domestic aluminum foil paper (material: aluminum foil thickness: 11 μm), and heated at 200 ° C. for 5 minutes in a regenerative furnace (product name: Muffle Furnace F0410, manufactured by Yamato Scientific).

<Color difference measurement>

ΔE * was measured on each sample before and after heating using a spectrophotometer (manufactured by X-Rite, product name SpectroEye). The measurement was performed under the conditions of light source D65, no light source filter, and viewing angle of 2 °. One sample was placed on a paper with ISO whiteness of 92%, and the spectrophotometer was pressed against the top.

The measurement was repeated five times for the portion coated with the heat-sensitive material, and the average value was used for analysis.

The results of the color difference measurement are shown in Table 1.

From the results in the above Table 1, it can be known that the color difference ΔE * before and after heating at 200 ° C for 5 minutes is applied to a paper roll as a heat-sensitive material containing an aqueous solution containing the substances shown in Table 1. In contrast, in the control group or Comparative Example 1, the color difference ΔE * was less than 15. In addition, regarding samples with a color difference ΔE * of 15 or more, although the color change was such that the color difference ΔE * before and after heating became 15 or more, under the observation of a functional inspector, uncomfortable colors were not recognized even after heating. .

On the other hand, regarding the control group or Comparative Example 1 in which the color difference ΔE * was not more than 15, the appearance after heating was slightly uncomfortable under the observation of a functional inspector compared to before heating.
