The above object has been achieved by the present invention, and a non-burning type flavor-generating product according to the present invention comprises a rod-shaped body having a plurality of vertical grooves formed on an outer peripheral surface thereof. It is wrapped by the outer wrapper,
The outer wrapper forms the vertical groove of the rod as an axial through passage.

According to the non-burning type flavor generating product of claim 1,
When the outer surface of the flavor generator is heated, the flavor in the outer wrapper, i.e., the flavor generating sheet, is generated from its inner surface in the form of vapor or aerosol in the axial through-passage, and therefore,
It is sucked through the mouth part. In the flavor generating product according to the second aspect, the flavor generating sheet forming the outer wrapper includes a tobacco flavoring material. In this case, the inhalation of vapor or aerosol generated from the tobacco flavoring material is pseudo smoking.

[0007] In the flavor generating product of the third aspect, the tobacco powder is also contained in the rod-like body, and in this case, the rod-like body is also heated so that not only the outer wrapper but also the tobacco powder in the rod-like body is removed. Also its flavor is generated in the form of steam or aerosol. The flavor-generating product according to claim 4 is provided with air permeability to the outer wrapper. In this case, the flavor in the form of steam or aerosol generated from the flavor-generating sheet is:
The air flows into the axial through passage together with the air passing through the outer wrapper.

The flavor-generating product according to claim 5 has a ventilation resistance of 5%.
It is set to 0 to 150 mmHg. Such a range of the ventilation resistance is the same as that of a normal filter cigarette, and does not give an unpleasant sensation when sucked.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a non-burning type flavor generating product includes a flavor generating rod 2 and a flavor generating rod 2.
And a filter plug 6 connected to one end of the filter paper via a tip paper piece 4 winding.
Forms the mouthpiece of the flavor generating product.

The flavor generating rod 2 has a rod-shaped body 8 therein, and a plurality of vertical grooves 10 are formed on the outer peripheral surface of the rod-shaped body 8. As is apparent from FIG. 2, the vertical grooves 10 are arranged at equal intervals in the circumferential direction, and extend from one end to the other end of the rod 8 in the axial direction thereof. The rod 8 is
The tobacco powder is contained in the base material. For example, the rod 8 can be obtained by mixing a tobacco powder, a tobacco extract component, a tobacco smoke concentration component, and the like with a binder, and extruding the mixture. In this case, it is preferable that the interior of the extruded rod 8 is not dense and has a certain degree of air permeability.

Further, instead of the extrusion molding, the rod-shaped body 8 can also be obtained by incorporating the tobacco powder, the tobacco extraction component and the tobacco smoke concentration component in the tow of the acetate fiber, and thermoforming the tow. it can. The above-mentioned filter plug 6 is also formed from an acetate fiber tow. The rod-shaped body 8 is wrapped by an outer wrapper 12, and the outer wrapper 12 forms the vertical groove 10 of the rod-shaped body 8 as an axial passage 14. In other words, as shown in FIG.
Are open at both ends.

The outer wrapper 12 is formed of a flavor-generating sheet having air permeability.
And a tobacco flavoring material 1 formed in layers on the inner surface of the nonwoven fabric 16 as shown in FIG.
8 is formed. Here, tobacco flavoring material 18
Is formed by applying a mixture of tobacco powder, a soluble component thereof and a flavoring agent generally used in the cigarette manufacturing industry onto the nonwoven fabric 16.

The ventilation resistance of the flavor-generating product can be reduced to 50 as a whole by adjusting the individual ventilation resistances of the filter plug 6, the rod-shaped body 8 and the outer wrapper 12, the number of the axial through-passages 14, and the passage cross-sectional area. It is set in the range of ~ 150mmHg. The above-mentioned non-burning type flavor generating product is heated from the outside without the flavor generating rod 2 being entirely or partially burned, and by this heating, the tobacco flavoring material 18 of the outer wrapper 12 and the rod-shaped body 8 The tobacco flavor of the tobacco powder is generated in each axial through-passage 14 in the form of vapor or aerosol. These vapors or aerosols
Along with the suction at the mouth end, the user from the mouth end, from the tip of the flavor generation rod 2, and through each axial through-passage 14 and the filter plug 6 together with the air flowing in through the outer wrapper 12, , Sent into the mouth of the smoker.

A part of the steam and the aerosol is
And it will also be sent into the smoker's mouth through the filter plug 6. Since the outer wrapper 12 can be wound along the outer peripheral surface of the rod 8, the flavor generating rod 2 can be manufactured in the same manner as a normal cigarette rod,
Its manufacture becomes easy.

Since the axial passages 14 of the flavor generating rod 2 are open at the end surface thereof, the air flows through the axial passages 14 without receiving the air passing through the outer wrapper 12. And the inhalation of flavor in the form of vapor or aerosol is possible. In this case, the heater unit for heating the flavor generation rod 2 may be any unit that inserts and receives the flavor generation rod 2 and heats the air on the tip side of the flavor generation rod 2 in the heater unit.

When the outer wrapper 12 is the flavor generating rod 2 having air permeability, the heater unit heats the flavor generating rod 2 not only from the front end side of the flavor generating rod 2 but also from outside the outer wrapper 12. Is there
Alternatively, it is sufficient that the flavor generation rod 2 is heated only from the outside of the outer wrapper 12. In this case, the heater unit disclosed in Japanese Patent Application Laid-Open No. 7-84627 can be used.

Further, the flavor generating product has a ventilation resistance of 50 to
Since it is in the range of 150 mmHg, the same suction resistance as that of a normal filter cigarette, that is, a smoking feeling can be provided. The invention is not restricted to the embodiments described above. For example, the rod 8 of the flavor generation rod 2 is not necessarily
The flavor is not limited to the one containing the tobacco powder, and the flavor may be generated only from the outer wrapper 12.

Further, the flavor contained in the flavor generating sheet forming the outer wrapper 12 and the flavor contained in the rod 8 are not limited to those described above, but include flavors other than tobacco and tobacco components, such as menthol, caffeine, and glycerin. Various sources can be used as the source of the flavor. The flavor generating sheet or rod 8 may contain a gas adsorbent such as activated carbon, silica gel, and activated alumina.

[0019]

As described above, according to the non-burning type flavor generating product of the first aspect, since the outer peripheral surface of the rod is covered with the outer wrapper made of the flavor generating sheet, the winding of the outer wrapper is easy. And its manufacture becomes easy. Since a plurality of axial through-paths are formed between the outer wrapper and the rod-shaped body, the flavor-generating product does not disturb the outer wrapper by guiding heated air to the axial through-passage at the tip side. It can be heated by burning and its flavor in the form of a vapor or aerosol can be inhaled through its axial penetration.

According to the flavor generating product of the second aspect, since the tobacco powder is contained in the rod-shaped body, if the rod-shaped body is also heated without burning, the flavor of the tobacco powder is in the form of vapor or aerosol. Occurs, which allows simulated smoking without sidestream smoke. According to the flavor generating product of claim 3, since the outer wrapper is provided with air permeability, if the flavor generating product is heated from at least one of the front end side and the outer peripheral side, the flavor generation product passes the flavor through the axial through-passage. And various heater units for heating the flavor-generating product can be used.

According to the fourth aspect of the present invention, since the whole airflow resistance is in the same range as that of a normal filter cigarette, there is no sense of incongruity in inhaling the flavor.
