Abstract

The carbonaceous heat source composition for non-combustible smoking articles of the present invention contains carbon and contains polyhydric alcohol in a proportion of 0.5 to 5% by weight. Moreover, the non-combustible smoking article of this invention is equipped with such a heat source.

Description

Carbonaceous heat source composition and non-combustible smoking article for non-combustible smoking article {CARBONACEOUS HEAT SOURCE COMPOSITION FOR NON-COMBUSTIBLE SMOKING ARTICLE AND NON-COMBUSTIBLE SMOKING ARTICLE}

The present invention relates to a carbonaceous heat source composition for a non-combustible smoking article, and a non-combustible smoking article.

Tobacco is a typical flavor generator that tastes the flavor in smoke (aerosol) through human taste and smell by burning tobacco leaves.

In recent years, non-combustible smoking articles have been developed for enjoying tobacco flavors and aerosols without burning tobacco leaves instead of or in addition to tobacco. These non-combustible smoking articles have an aerosol-generating section comprising a heat source, which is a heat generating member attached to the tip, and an aerosol-generating material having retained a flavor component on a suitable substrate, wherein the heat source and the aerosol-generating section are physically separated from each other. have. This type of smoking article burns a heat source and heats the combustion heat without burning the aerosol generating material to generate an aerosol containing a flavor component, and the smoker sucks the aerosol to taste the flavor. . As the heat source, only a carbonaceous heat source is used.

Conventionally, in the non-combustible smoking article, the amount of aerosol obtained at the time of smoking is small compared with the amount of the aerosol obtained by the tobacco etc. which were wound by the usual paper, and the satisfaction of smoking is not obtained in many cases. Therefore, proposals have been made to increase the amount of aerosol generated in the non-combustible smoking article.

Japanese Patent Laid-Open No. 5-207868 discloses a carbonaceous fuel composition for a fuel element containing carbon, a binder, tobacco, and sodium. By adding sodium to the fuel composition, smoke speed and puff calories are improved to improve the amount of aerosol generated.

However, in this carbonaceous fuel composition, when the amount of sodium added is increased, the number of aerosols increases, while the amount of carbon monoxide produced also increases considerably.

DISCLOSURE OF INVENTION

The present invention provides a non-combustible carbonaceous heat source composition for a non-combustible smoking article that can increase the amount of aerosol generated while minimizing an increase in the amount of carbon monoxide produced by combustion of a heat source, and a non-combustible type having a heat source composed of such a composition. It aims at providing smoking articles.

In order to solve the above object, according to the first aspect of the present invention, there is provided a carbonaceous heat source composition for a non-combustible smoking article comprising carbon and containing polyhydric alcohol at a ratio of 0.5 to 5% by weight. do.

Best Mode for Carrying Out the Invention

Hereinafter, the present invention will be described in more detail.

The carbonaceous heat source composition for non-combustible smoking articles of the present invention contains carbon and contains 0.5 to 5% by weight of the total weight of the carbonaceous heat source composition. If the amount of polyhydric alcohol is less than 0.5% by weight, the amount of aerosol (TPM) generated does not increase significantly. Moreover, when the amount of polyhydric alcohol exceeds 5 weight%, the increase rate of carbon monoxide (CO) by combustion of a heat source will become large. In particular, when it contains 1.0 weight% or more (5 weight% or less) of polyhydric alcohol, the heat source formed from the said composition becomes a thing which significantly improved complexability. Moreover, when using the heat source containing 1.0 weight% or more (5 weight% or less) of polyhydric alcohol, the amount of TPM will further increase.

As the polyhydric alcohol, glycerin, propylene glycol, or the like can be used.

Usually, in addition to polyhydric alcohol and carbon, the carbonaceous heat source composition of this invention contains the binder for binding carbon. It is preferable that the quantity of a binder is 5-15 weight% of the total weight of a carbonaceous heat source composition. When the amount of the binder is less than 5% by weight, the binding force by the binder tends not to be sufficiently exhibited. If the amount of the binder exceeds 15% by weight, the amount of carbon decreases, so that the heat source tends not to be sufficiently burned.

As a binder, arginate (for example, ammonium salt, sodium salt), carboxymethylcellulose or its salt (for example, sodium salt), pectin, carrageenan or its salt (for example, sodium salt), guar gum Etc. can be used.

Moreover, the carbonaceous heat source composition of the present invention may include calcium carbonate (particles). When calcium carbonate contains this, it is preferable to mix | blend in the ratio of 30 to 55 weight% of the total weight of a carbonaceous heat source composition. If the amount of calcium carbonate is less than 30%, the combustion suppression effect tends to not be sufficiently exhibited. In addition, when the amount of calcium carbonate exceeds 55% by weight, the number of puffs of the smoking article is significantly reduced, which is not practically appropriate.

As described above, the carbonaceous heat source composition contains 0.5 to 5% by weight of a polyhydric alcohol, and the balance is carbon, including the case of further containing a binder and / or calcium carbonate. There is no restriction | limiting in particular in the origin (raw material) of the carbon (particle) to be used, All well-known carbon can be used.

The carbonaceous heat source composition of the present invention can be molded as a heat source by molding means such as extrusion molding. At this time, the polyhydric alcohol is mixed with other raw materials before molding, or a polyhydric alcohol supply nozzle or the like is attached to the mixing / kneading portion of the molding machine, and the polyhydric alcohol is transferred to other raw materials from the nozzle during molding in the molding machine. Can supply

The non-combustible smoking article of the present invention includes an aerosol-generating section that generates an aerosol by heating, and a heat source that is physically separated from the aerosol-generating section at one end of the aerosol-generating section. It consists of the carbonaceous heat source composition of this invention. Since the smoking article of the present invention is a non-combustion type, a combustion line generated at the time of combustion, which is seen as a combustion type smoking article, does not exist at all in the aerosol-generating section.

In the non-combustible smoking article of the present invention, compared to the non-combustible smoking article using a carbonaceous heat source containing no polyhydric alcohol, while suppressing the increase rate of carbon monoxide to, for example, 5% or less, the TPM is, for example, 16.0% or more. Can be increased.

In particular, the heat source containing the polyhydric alcohol in the ratio of 1.0-5 weight% can be improved 11% or more compared with the carbonaceous heat source whose ignition time does not contain a polyhydric alcohol.

Hereinafter, an example of the non-combustible smoking article of the present invention will be described with reference to FIG. 1.

The non-combustible smoking article 10 shown in FIG. 1 has an aerosol-generating section 11 that is heated to generate an aerosol containing a flavor component. In the example shown in FIG. 1, this aerosol-generating section 11 is composed of a first aerosol-generating portion 111 and a second aerosol-generating portion 112. The first aerosol-generating portion 111 is a cylinder (not shown) formed of a thermally stable material such as aluminum or stainless steel, for example, filled with sheet tobacco and tobacco, and the second aerosol-generating portion 112. Is filled with tobacco, for example, in the same cylinder (not shown). The first aerosol-generating portion 111 and the second aerosol-generating portion 112 are in contact with each other and are located in the longitudinal direction of the smoking article 10.

At the tip of the aerosol-generating section 11 (the tip of the first aerosol-generating portion 111), the columnar carbonaceous heat source 12 made of the composition of the present invention is provided so as to be physically separated from the aerosol-generating section 11. It is. The heat source 12 is provided with a through hole 121 for inserting external air in the axial direction. The heat source 12 is normally surrounded by the heat-resistant member 13 which consists of glass wool, for example, the outer periphery. An ordinary filter 14 can be attached to the rear end of the aerosol-generating section 11 (the rear end of the second aerosol-generating portion 112). The entire outer circumference of the aerosol-generating section 11 and the filter 14 and the partial outer circumference of the heat source 12 surrounded by the heat-resistant member 13 are wound by a foreskin material 15 made of a heat insulating material. These three members are integrated by this. Such a non-combustible smoking article may have the appearance of a normal cigarette.

1 is a cross-sectional view showing an example of a non-combustible smoking article.

2 is a graph showing the relationship between the glycerin content, the TPM increase rate and the complexation improvement rate.

Hereinafter, although an Example demonstrates this invention, this invention is not limited to these.

Examples 1-4, Comparative Example 1

As shown in Table 1 below, carbon from a composition consisting of glycerin (0.5 to 5 wt%), carbon (45.0 to 49.5 wt%), a binder ammonium arginate (10 wt%), and calcium carbonate (40.0 wt%) Molded vaginal heat source. The smoking article of the structure shown in FIG. 1 was produced using this carbonaceous heat source. As a comparative example 1, the smoking article was produced similarly using the carbonaceous heat source which did not add glycerin. These smoking articles were smoked and burned by an automatic smoking machine under standard smoking conditions (TIOJ Standard Measurement Method [Fourth Edition Appendix 1]), and the amount of TPM produced, the amount of CO produced and the number of puffs were measured.

In addition, the ignition time of the heat source was measured about the smoking articles of Examples 1-4 and Comparative Example 1. The first puff is arbitrarily set under conditions of 2 seconds / 35 cc of air suction amount and ignited with a lighter, and at the time of the second puff under standard smoking conditions (TIOJ standard measurement method [4th edition] Annex 1), When the whole front end surface burned and combustion of the whole front end surface of this heat source was observed 5 or more times also regarding the puff after the 2nd time, the 1st puff setting value was made into ignition time.

The above result is shown in Table 2. Table 2 also shows the TPM increase rate, CO increase rate, and complex improvement rate calculated based on the TPM generation amount, CO generation amount, and ignition time of Comparative Example 1. Moreover, the graph which shows the relationship between the glycerin content rate, TPM increase rate, and complex improvement rate shown in Table 2 is shown in FIG. In FIG. 2, the line a shows the TPM increase rate, and the line b shows the ignition improvement rate.

Figure 112008067359710-pct00001

Figure 112008067359710-pct00002

As the above result showed, the smoking article of Examples 1-4 which used the carbonaceous heat source obtained from the carbonaceous heat source composition containing glycerin in the ratio of 0.5-5 weight% uses the carbonaceous heat source which does not contain glycerin. Compared with the smoking article of the comparative example 1, TPM production | generation amount is 16.4% or more (up to 35.8%). In addition, in the smoking articles of Examples 1-4, there is almost no increase of CO. In addition, the amount of TPM produced is improved as the glycerin content rate increases from 0.5 weight% (Example 1) to 5 weight% (Example 4). In particular, when the glycerin content is 1.0% by weight or more, the amount of TPM produced is remarkably improved (Examples 2 to 5). Furthermore, regarding the ignition time, the glycerin content rate is 1% or more (Examples 2 to 5), and 11.1 to 16.7% is improved. When the glycerin content was 0.5% (Example 1), the ignition time was not improved, but the TPM increase rate was 16.

It was improved to 4%.

That is, the amount of TPM produced can be increased by adding glycerin, while controlling the amount of carbon in the heat source composition to suppress the increase in the amount of CO produced.

Also, as is clear from Fig. 2, the addition of more than 5% of glycerin does not significantly increase the TPM increase rate, and the amount of more than 5% of glycerin is undesirable because it may increase the thermal decomposition products. .

As described above, according to the present invention, in the carbonaceous heat source composition for a non-combustible smoking article, by adopting a simple configuration in which the amount of the polyhydric alcohol is set within the range of 0.5 to 5% by weight, The amount of aerosol generated from the aerosol-generating member can be increased while minimizing the increase in the amount of carbon monoxide produced.

New benefits and modifications are easy for those skilled in the art. Therefore, in the broader aspect, this invention should not be limited to the specific base material and typical aspect described here. Accordingly, various modifications may be made without departing from the spirit or scope of the general concept of the invention as defined by the appended claims and their equivalents.
