Wrappers for non-combustion heated smoking articles, non-combustion heated smoking articles and electrically heated smoking systems

The present invention relates to wrappers for non-combustion heated smoking articles, non-combustion heated smoking articles and electrically heated smoking systems.

BACKGROUND OF THE INVENTION [0002] Non-combustion heating type smoking articles of a type in which heating is performed around a tobacco rod containing shredded tobacco and volatile components are delivered to the user are known. In a non-combustion heating type smoking article, a tobacco rod wrapped in wrapping paper is heated, but unlike conventional cigarettes, the tobacco rod remains unburned even after use (after heating).

In conventional cigarettes, it is common to use white (colorless) paper as the wrapping paper for recommending shredded tobacco, although logos and the like may be attached thereto.

It has been found that in non-combustion heating type smoking articles, when wrapping paper used in conventional cigarettes is used as wrapping paper recommended for shredded tobacco, discoloration that is unpleasant to the user may occur due to heating during use.

Therefore, an object of the present invention is to provide a wrapper for a non-burning heating type smoking article, which does not cause discomfort with regard to the appearance that may occur due to heating.

In order to solve the above problem, the present inventors focused on making the unpleasant discoloration less conspicuous by using wrapping paper having a portion having a certain or higher color difference ΔE* compared to before heating after heating.

Paper whose main material is pulp is discolored to a tea system when heated at a certain temperature or higher, but the cause is physical due to thermal decomposition of the constituents of pulp or paper, so such discoloration cannot be easily prevented. However, even if discoloration occurs due to burning, in order to prevent the discoloration from being recognized as an unpleasant color, a specific heat-sensitive material is added to the wrapping paper in advance, and a certain color difference occurs before and after heating, so that rather unpleasant discoloration is prevented. I found that it can be made unobtrusive.

As described above, the non-combustion heating type smoking article comprises a cigarette rod portion composed of a filler 11 and a first wrapping paper 12 for recommending the filler 11, and an end portion opposite to the tobacco rod portion. The tobacco rod part and the mouthpiece part are connected by using a second wrapper identical to or different from the one recommended for the filler. When the non-combustion heating type smoking article is wrapped around an electric heating type device, the outer circumferential surface of the tobacco rod and the second wrapping paper (chip paper 13) connecting the tobacco rod and the branch pipe 14 A part of the configured outer circumferential surface contacts the heat transfer member 25 inside the electric heating type device 20 .

The heater 24 inside the electric heating device 20 generates heat under control by the control unit 22 . As the heat is transferred to the tobacco rod of the non-combustion heating type smoking article through the heat transfer member 25, the aerosol generating base and flavor components included in the filler 11 of the tobacco rod volatilize together.

Due to heating by the heater 24, the tobacco rod is generally heated to 150 to 250 °C.

When measuring ΔE*, the heating temperature of the wrapping paper is 200°C and the time is 5 minutes, which is set on the premise of using the electrically heated smoking system according to the embodiment of the present invention.

Vapor containing the aerosol-generating material and flavor components generated by heating is aerosolized inside the branch pipe portion 14 by the mechanism described above, and passes through the filter portion 15 of the non-combustion type smoking article 10. It reaches the user's oral cavity.

Example

Although the present invention will be described more specifically with reference to examples, the present invention is not limited to the description of the following examples, unless the gist thereof is exceeded.

<Preparation of paper samples>

Commercially available cigarette rod paper was cut into 5 cm × 5 cm pieces.

In addition, as the heat sensitive material, substances shown in Table 1 below were selected, and aqueous solutions of each substance were prepared at the concentrations shown in Table 1. Using a brush, each aqueous solution was applied to the cut paper in a width of 3 cm.

In addition, as a control, the cut paper was used with nothing applied. In addition, commercially available cigarette rod paper contains about 1.2% by weight of citric acid as a flame retardant relative to the total amount of the paper (Table 1 shows the coating amount, but it is not coated).

Further, commercially available self-extinguishing wrapping paper for tobacco rods (a self-extinguishing agent is coated on the surface in contact with shredded tobacco) was prepared as Comparative Example 1.

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

< Color difference measurement >

ΔE* was measured for each sample before and after heating using a spectrophotometer (manufactured by X-Rite, product name SpectroEye). The measurement was carried out by placing one sample on a sheet of paper having an ISO whiteness of 92% and pressing the spectrophotometer firmly on it under conditions of a viewing angle of 2° without a light source D65 and a light source filter.

The measurement was repeatedly performed at 5 locations on the portion where the heat sensitive material was applied, and the average value was used for analysis.

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

From the results of Table 1 above, it was found that the color difference ΔE* before and after heating at 200 ° C. for 5 minutes was 15 or more when the aqueous solution containing the substances shown in Table 1 as the heat-sensitive material was applied to the wrapping paper, and the control or comparative example 1 In , the color difference ΔE* did not reach 15. In addition, the sample having a color difference ΔE* of 15 or more was discolored to such an extent that the color difference ΔE* before and after heating was 15 or more, but when the panelist observed the sample, it was not recognized as an unpleasant color even after heating.

On the other hand, as for the control and Comparative Example 1 having a color difference ΔE* of less than 15, the panelist observed that the appearance after heating gave a slightly unpleasant impression compared to before heating.
