201002219 六、發明說明： 【發明所屬之技術領域】 特別是關於具備包含香 本發明係關於—種吸煙物品 味成分之濾嘴的吸煙物品。 【先前技術】 吸煙物品、例如香煙係由香煙絲、紙、滤嘴、或依情 況之填充在濾嘴之活性炭等各種素材所構成。與者，香煙 專吸煙物品係添加有各種香味成分，而創造出每個香煙努 品所特有之味道或香味。近年來，為了品脅更廣泛之香味， 係改變香煙本身所呈現之香味，或者為了增強香味而詞_附 設在香煙之濾嘴添加香味成分。 就對濾嘴香煙添加香味成分之添加方法而言，以往係 採用直接將香味成分添加在濾'嘴之方法、使香咮成分吸附 在活性炭等多孔性粒子而將該多孔性粒子添加在濾' 嘴之方 法專。然而，在具有直接添加香味成分之濾、嘴的香煙中， 透過香煙製品之流通過程，由於包裝内之吸附平衡，香味 成分會從濾嘴部移行至其他香煙材料部，因而有無法穩定 地品嘴香味之傾向。具備含有吸附香味成分之多孔性板子 之滤嘴的香煙係在吸煙時，香味成分從多孔性粒子之脫離 不完全’而無法釋放出充分之香味成分。 再者：，在例如曰本特開平4-75578號公報及曰本貫公 平5-45198號公報中，揭示有一種將以天然多糖類被覆香 料之粒子裝填在濾嘴，在吸煙時粉碎粒子而使香味成分發 散之形式的香煙。再者，在日本特開平10-279986號公報 321200 3 201002219 中，揭示有一種具備添加包接有香味成分之環糊精之滤嘴 的香煙。此外，在日本實公昭48-40719號公報中’揭示有 一種將以聚乙婦醇等被覆之香料膠囊添加在濾、嘴之香煙 然而，該等香煙並非皆可在不吸煙時穩定地保持香味成 分，且在吸煙時並非皆可立刻釋放出香味成分。 【發明内容】 (發明所欲解決之課題） 因此，本發明之目的在於提供一種穩定地保持香味成 分，且在吸煙時立刻可釋放出香味成分之吸煙物品。 (解決課題之手段） 在不吸煙時，為了在濾嘴中穩定地保持香味成分’較 佳為使香味成分在濾嘴中固定化，因此最好將香味成分導 入至適當之基體材料中。此外，在考慮到在吸煙時使香味 成分有效率地釋放出時，基體材料係以容易因吸煙時產生 之氣溶膠所包含之水分而溶解者為佳，且較佳為與氣溶膠 之接觸表面積大。因此’較佳為儘可能將香味成分導入粒 子杈小之水溶性基體中。考慮上述見解，本發明人等係在 經過精心研究之結果發現，藉由將香味成分導入具有i至 100以111之範圍内之粒子徑且顯示20# m以下之平均粒子徑 的水溶性基體粒子中，即可達成所希望之目的。 ^亦即’依據本發明而提供一種吸煙物品，其具有氣溶 膠產生部及附設在前述氣溶膠產生部之濾嘴部，其中，前 V遽^ °卩係含有複數個香味放出性粒子’前述複數個香味

Description of the Invention: [Technical Field to Which the Invention Is Applicable] In particular, a smoking article including a filter containing a flavor component of a smoking article of the present invention is provided. [Prior Art] A smoking article, for example, a cigarette, is composed of various materials such as cigarette silk, paper, a filter, or activated carbon filled in a filter depending on the situation. With you, cigarettes are made with a variety of flavoring ingredients to create a unique taste or aroma for each cigarette. In recent years, in order to threaten a wider fragrance, the flavor of the cigarette itself is changed, or the flavor is added to the filter of the cigarette to add a flavor component. In the method of adding a flavor component to a filter cigarette, a method of directly adding a flavor component to a filter mouth, and adsorbing a camphor component to a porous particle such as activated carbon to add the porous particle to the filter is conventionally used. The method of mouth is specialized. However, in a cigarette having a filter or a mouth directly added with a flavor component, the flow of the cigarette product is transferred, and the flavor component migrates from the filter portion to the other cigarette material portion due to the adsorption balance in the package, so that the product cannot be stably stabilized. The tendency of the mouth to smell. A cigarette having a filter containing a porous plate that adsorbs a flavor component is incompletely detached from the porous particles when smoking, and a sufficient flavor component cannot be released. Further, in Japanese Patent Publication No. Hei 4-75578 and Japanese Patent Publication No. Hei 5-45198, it is disclosed that a particle coated with a natural polysaccharide-based perfume is filled in a filter to pulverize particles during smoking. A cigarette in the form of a scented component. Further, a cigarette having a filter for adding a cyclodextrin containing a flavor component is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei 10-279986, No. Hei. In addition, Japanese Laid-Open Patent Publication No. SHO 48-40719 discloses a cigarette in which a fragrance capsule coated with polyephedol or the like is added to a filter or a mouth. However, not all of the cigarettes can stably maintain the fragrance when not smoking. Ingredients, and not all of them can be released immediately when smoking. DISCLOSURE OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION Therefore, an object of the present invention is to provide a smoking article which stably retains a flavor component and which can release a flavor component immediately upon smoking. (Means for Solving the Problem) In order to stably maintain the flavor component in the filter when not smoking, it is preferable to fix the flavor component in the filter. Therefore, it is preferable to introduce the flavor component into an appropriate base material. Further, in consideration of efficient release of the aroma component at the time of smoking, the matrix material is preferably dissolved by moisture contained in the aerosol generated during smoking, and preferably has contact surface area with the aerosol. Big. Therefore, it is preferred to introduce the flavor component into the water-soluble matrix of the small particle size as much as possible. In view of the above findings, the present inventors have found through careful study that water-soluble base particles having an average particle diameter of 20# m or less are introduced by introducing a flavor component into a particle diameter having a range of i to 100 in the range of 111. In order to achieve the desired purpose. ^ In other words, according to the present invention, there is provided a smoking article having an aerosol generating portion and a filter portion attached to the aerosol generating portion, wherein the front V遽^°卩 system contains a plurality of flavor releasing particles' Each of the plurality of flavor-releasing particle systems respectively comprises a water-soluble matrix containing a flavor component, and has a particle diameter in the range of 1 to 100 # m and exhibits a particle diameter of 2 〇 ym or less in the range of 4 321200 201002219. 4-Α» Jftv J2. Λτΐι - average particle diameter [Embodiment] _ The smoking article of the present invention is included in the filter portion of the plurality of flavor-releasing particles in the aerosol generating portion.
