JP5895067B2 - Non-burning flavor suction tool - Google Patents

Description

  The present invention relates to a non-burning type flavor suction tool.

  Conventionally, as an alternative to ordinary cigarettes (cigarettes), there is a non-burning product that has a flavor source such as tobacco leaves and a holder that contains the flavor source, and provides flavor components to the user without burning the flavor source. A type flavor suction tool is known (see, for example, Patent Document 1).

  Moreover, the cigarette which comprises the microcapsule containing a fragrance | flavor in a filter part is known (for example, refer patent document 2).

  Further, there is a smokeless tobacco product for oral use such as snuff tobacco used by a user in the oral cavity, and a smokeless tobacco product for oral use having a capsule filled with a liquid in a water-permeable bag containing a tobacco raw material. It is known (see, for example, Patent Document 3).

  In the non-burning type flavor inhaler disclosed in Patent Document 1, it is desirable to include a component that can be volatilized at room temperature in the flavor component provided to the user because it does not accompany the burning of the flavor source, but it is highly volatile. Since the flavor component is volatilized in large quantities during production, transportation, and storage, there is a problem that the flavor may be deteriorated.

  In addition, in the cigarette disclosed in Patent Document 2, since the microcapsule is disposed between the chip paper (Tipping paper) and the filter plug, the microcapsule is included in the microcapsule when the microcapsule is crushed. There is a problem that the fragrance penetrates into the filter plug and the fragrance component is not efficiently released by suction.

  In addition, since the non-burning type flavor inhaler disclosed in Patent Document 1 does not accompany the burning of the flavor source, the amount of the flavor component delivered to the user by the non-burning type flavor inhaler is larger than that of the cigarette. Few.

  In the cigarette disclosed in Patent Document 2, a vent hole is formed between the tobacco portion, which is a flavor source, and the location where the microcapsule is disposed, but the non-combustion type flavor suction tool disclosed in Patent Document 1 In this case, if an air hole is formed between the flavor source and the location of the microcapsule, the amount of air passing through the flavor source during suction is reduced, and the flavor derived from the flavor source is further reduced. It is difficult to adopt the same configuration as the cigarette disclosed in the above.

  Further, as a modified example of Patent Document 2 in which a configuration in which microcapsules are arranged between an outer layer and an inner layer of a chip paper having a two-layer structure is disclosed, an outer layer and an inner layer of a holder having a two-layer structure are disclosed. If a non-burning type flavor suction device is used in which a microcapsule is arranged between the flavor source and the location where the microcapsule is placed, the ventilation channel of the microcapsule There is a problem that the perfume component is not efficiently released because it hardly passes through the arrangement location.

  Further, when the tobacco product for oral cavity disclosed in Patent Document 3 is employed as a flavor source of a non-burning type flavor suction tool, the microcapsules are arranged together with a powdery flavor source enclosed in a bag-like pouch. Therefore, the microcapsules are difficult to fix, it is difficult to specify the position of the capsules, and it is difficult to crush the microcapsules in order to release the fragrance.
