The present invention relates to carbonaceous compositions of the heater is non-combustible Smoking products and Smoking product of this type.

Tobacco is a typical aromatic material, emits the fragrance of smoke (aerosol)generated by burning tobacco leaves, which is sensed by receptors of the taste and smell of a man.

In recent years, to replace or Supplement tobacco created tobacco products non-flammable type to get pleasure from the perception of aroma and taste of tobacco, and to get pleasure from the perception of an aerosol without burning tobacco leaves. These tobacco products are non-combustible type includes a heater, which is the element that generates heat, which is installed at the tip, and aerosol generating section that contains a material for the formation of aerosol formed from the respective substrate, which is applied to a component which aroma. The heater is physically separated from the aerosol generating section. In the Smoking product of this type of heater is ignited, and the heat from the combustion heats the element to the aerosol formation without it burning for aerosol formation containing a component which aroma. Smokers inhale the aerosol to get pleasure from the perception of flavor. The heater is used exclusively plastiras the th heater.

Many conventional tobacco products non-flammable type generate fewer aerosol when Smoking than regular cigarettes, and do not provide enough satisfaction from Smoking. Thus, had the idea of generating an increased amount of the aerosol.

In published application Japan No. 5-207868 disclosed carbonaceous fuel composition for fuel element containing: carbon, binder, tobacco and sodium. By adding sodium in the fuel composition increases the rate of decay and the caloric value of the torque and increase the output of the aerosol in the "Smoking".

However, with increasing amount of added sodium in this carbonaceous fuel composition of the release of the aerosol increases, but this greatly increases the amount of carbon monoxide.

The present invention is to create a carbonaceous composition for heater Smoking products are non-combustible type, through which you can increase the amount of aerosol that can be generated at the same time reducing the amount of carbon monoxide that can be generated in the combustion heater, and the aim of the present invention is to provide a Smoking product is non-combustible type, containing a heater comprising this composition.

To achieve the above objectives according to the first aspect of the present invention created carbonaceous composition for heater Smoking products are non-combustible type, characterized in that it contains coal and 0.5-5.0 wt.% a polyhydric alcohol.

In the drawings:

Figure 1 is a longitudinal cross-section of an exemplary Smoking products are non-combustible type;

Figure 2 - chart of the relationship between content of glycerin and increase TPM or increase the speed of ignition.

The present invention is described below in more detail.

Carbonaceous composition of heater Smoking products are non-combustible type according to the invention contains coal and 0.5-5.0 wt.% a polyhydric alcohol of the total weight of the carbonaceous composition of the heater. If the amount of polyhydric alcohol is less than 0.5 wt.%, the number of generated aerosol (TPM) is not increased substantially. In addition, if the amount of polyhydric alcohol exceeds 5.0 wt.%, it increases the amount of carbon monoxide (CO)from the combustion heater. In particular, if the polyhydric alcohol is contained in an amount of 1.0 wt.% or more (5.0 wt.% or less), it significantly improves the Flammability of the heater is made of this composition. Also, if you use a heater containing a polyhydric alcohol in an amount of 1.0 wt.% or more (5.0 wt.% or less), the amount of TPM increases to a greater extent.

As a polyhydric alcohol can be used glycerin, propylene glycol, etc.

In General whisteria the second composition of the heater according to the invention contains a binder for binding of coal in addition to the polyhydric alcohol and coal. The amount of binder is preferably from 5-15 wt.% of the total weight of the carbonaceous composition of the heater. If the amount of the binder is less than 5 wt.%, it has a tendency to manifest binding properties of the binder is insufficient. Also, if the amount of the binder exceeds 15 wt.%, the amount of coal decreases, resulting in has a tendency to under-burning heater.

As a binder can be used alginate (e.g., ammonium salt and sodium salt), carboxymethyl cellulose or its salt (e.g. sodium salt), pectin and carageenan or its salt (e.g. sodium salt), guar gum, etc.

In addition, carbonaceous composition of the heater according to the invention may contain calcium carbonate (particle). Calcium carbonate, in his introduction, is preferably introduced in a ratio of from 30-55 wt.% of the total weight of the carbonaceous composition of the heater. If the amount of calcium carbonate is less than 30%, there is a tendency that the effect of suppressing receive insufficient. Also, if the amount of calcium carbonate exceeds 55 wt.%, the number of puffs when Smoking Smoking products is significantly reduced and, thus, such carbonaceous heater is practically unacceptable.

Carbonaceous composition of the unit's electric is according to the invention contains 0.5 to 5.0 weight. % polyhydric alcohol, as mentioned above, and the rest is carbon, including the case where the heater further comprises a binder and / or calcium carbonate. Source (raw material) coal (particles) is not particularly limited, and can be used any known type of coal.

Carbonaceous composition of the heater according to the invention can be molded in the form of a heater by applying the technology of molding, such as extrusion. This polyhydric alcohol can be mixed with other materials prior to molding or can be submitted to other raw materials, using another method, in which a nozzle for supplying a polyhydric alcohol attached to the mixing/kneading part moulding machine for feeding a polyhydric alcohol from the nozzle in the form used on the molding machine.

Smoking product is non-combustible type according to the invention contains a section for the formation of aerosol by heating, and the heater is placed on the end of the aerosol generating section so that it was physically separated from the aerosol generating section, and the heater consists of carbonaceous compositions of the heater according to the invention. So as a Smoking product according to the invention is non-flammable product type, line combustion occurring during mount the Oia and observed in the case of Smoking the product of the burning type, does not exist in the aerosol generating section.

Using crack product is non-combustible type according to the invention can increase the TPM, for example, by 16.0% or more, at the same time suppressing the increase in the formation of carbon monoxide, for example, 5% or less in comparison with Smoking product is non-combustible type, which use coaly heater, not containing polyhydric alcohol.

In particular, the characteristics of the heater containing a polyhydric alcohol in a ratio of from 1.0 to 5.0 wt.%, can be improved in relation to the time of ignition by 11% or more in comparison with carbonaceous heat source, not containing polyhydric alcohol.

The example of Smoking products are non-combustible type according to the invention is described with reference to Figure 1.

The Smoking article 10 non-combustible type shown in figure 1, contains a section 11, in which when heated forms a spray that contains a component which aroma. In the example shown in figure 1, section 11 for aerosol formation consists of a first part 111 for aerosol formation and the second part 112 for aerosol formation. The first part 111 for aerosol formation contains a hollow cylinder made of heat-resistant material, such as aluminum or stainless steel (not shown)filled with, for example, fine-cut tobacco or tobacco crumbs. W heaven part 112 for aerosol formation contains like a hollow cylinder (not shown), filled, for example, fine-cut tobacco or tobacco crumbs. The first part 111 for aerosol formation and the second part 112 for aerosol formation are in contact with each other and are arranged in the longitudinal direction of the Smoking articles 10.

Cylindrical carbonaceous heater 12, is made of the composition according to the invention is located near the front end section 11 for aerosol formation (the front end of the first part 111 for aerosol formation) so that it was physically separated from section 11 for aerosol formation. The heat source 12 in the axial direction is formed a through hole 121 to the suction of external air. The outer periphery of the heater 12, in General, is surrounded by a heat-resistant element 13 consisting, for example, fiberglass. At the rear end of the section 11 to aerosol formation (at the rear end of the second part 112 for aerosol formation) may be positioned normal to the filter 14. The entire outer periphery of the section 11 for aerosol formation and filter 14 and part of the outer periphery of the heater 12, is surrounded by a heat-resistant element 13 is wrapped in a wrapping material 15 made of insulating material, to combine them into one. This Smoking product is non-combustible type may have the appearance of a conventional cigarette.

The present invention is described Nizhyn Examples but the present invention is not limited to these examples.

Examples 1-4, Comparative example 1

As shown in Table 1, coaly heater was molded from the compositions containing glycerol (0.5-5.0 wt.%), coal (45.0-a 49.5 wt.%), alginate ammonium (10 weight%), which served as a binder and calcium carbonate (40 wt.%). Smoking product having the design shown in figure 1, was fabricated using this carbonaceous heater. For Comparative example 1 was manufactured Smoking product in the same manner as in the above example, using carbonaceous heater that has not been added glycerin. These Smoking products, respectively, were subjected to tests for burning when smoked on an automatic Smoking machine under standard conditions area [according to the standard method of measurement TIOJ (fourth edition), Appendix 1] for measuring the amount of generated TPM and CO and determine the number of puffs.

Was determined using tobacco products described in Examples 1-4 and Comparative example 1, the time of ignition of the heater. The conditions of the first tightening the choice set so that the amount of air in prosise was 35 cm3/2C for igniting Smoking articles using a cigarette lighter. the hen all end surface of the heater was lit when the second tightening under standard conditions area [according to the standard method of measurement TIOJ (fourth edition), Annex 1], and it is burning the entire leaf surface was observed five or more times after the second tightening determined set value of the first torque as the time of ignition.

The results of the above tests are presented in Table 2. Table 2 also shows the results of tests showing the increase in TPM, the increase in CO and an increase in the speed of ignition, which was calculated by taking as a base the number of generated TPM and CO, and the time of ignition, obtained in Comparative example 1. In addition, the chart (see Figure 2) shows the relationship between the content of glycerin and increase TPM or increase the speed of ignition. In figure 2 the lineandshows the increase (%) TPM and linebshows the increase (%) rate of fire.

As shown by the above test results, tobacco products of Examples 1-4, which used the carbonaceous heat sources, obtained from carbonaceous compositions for heat sources containing glycerol in a ratio of from 0.5 to 5.0 wt.%, provide an increase in the number of generated TPM by 16.4% or more (max - 35.8%), in comparison with Smoking product of Comparative example 1, which used a carbonaceous heater, which does not contain glycerin. Also Smoking articles of Examples 1-4, essentially showed no increase in the amount of CO. The number of generated TPM increased with increase in the content of glycerol in the range of from 0.5 wt.% (Example 1) to 5.0 wt.% (Example 4). In particular, when the glycerin content was 1.0 wt.% or more, the resultant TPM was significantly increased (Examples 2-5). In addition, the time of ignition is improved by 11.1-16.7 per cent, when the glycerin content was 1% or more (Examples 2-5). The sample, in which the glycerin content was 0.5% (Example 1)showed an increase in the education TPM 16.4%, although the time of ignition has not improved.

In particular, the quantity of generated TPM can be increased by adding glycerol, but at the same time constrained by the increase in the number of formed CO by regulating the amount of carbon in the composition of the heater.

As clearly seen when considering the diagram in figure 2, even if glycerin is added in excess of 5%, the increase (%) TPM insignificant improved and there is also the fear that in the presence of glycerol in amounts exceeding 5%, increases the amount of pyrolysis products, which is undesirable.

On the basis of the invention (described above), we created a simple construction in which, in accordance with studies, the number is the amount of polyhydric alcohol in carbonaceous compositions heater Smoking products are non-combustible type is from 0.5 to 5.0 wt.%, thus, the amount of aerosol generated in the element for aerosol formation can be increased while reducing the amount of generated carbon monoxide in the combustion heater.
