Artículo para fumar.Article for smoking
La presente invención se refiere a un artículo para fumar y, más específicamente, a un artículo para fumar que contiene un elemento de producción de aroma que produce el aroma por calentamiento sin arder.The present invention relates to an article for smoking and, more specifically, to a smoking article that It contains an aroma production element that produces the aroma by heating without burning.
Ya se conocen y se han propuesto varios tipos de artículos para fumar para disfrutar de los aromas y el humo del tabaco sin quemar las hojas de tabaco. Ejemplos típicos de artículos para fumar del tipo en el que el aroma es producido por un elemento generador de calor montado en el extremo distal del artículo se describen, por ejemplo, en la Publicación KOKAI de Solicitud de Patente Japonesa nº 63-35468, Publicación KOKAI de Solicitud de Patente Japonesa nº 6-46818, correspondiente al documento EP 0545186, Patente Japonesa nº 1681670, Patente Japonesa nº 3012253 y Publicación KOKAI de Solicitud de Patente Japonesa nº 2-84168. En estos artículos para fumar, se introduce elemento productor de aroma granular o en hoja, entre el elemento generador de calor y su extremo correspondiente a la boca. A medida que el elemento de producción de aroma es calentado por el calor del elemento generador de calor, los componentes del aroma se vaporizan y se liberan.Several types of smoking articles to enjoy the aromas and smoke of tobacco without burning the tobacco leaves. Typical examples of articles for smoking of the type in which the aroma is produced by an element heat generator mounted on the distal end of the article is described, for example, in the KOKAI Publication of Application for Japanese Patent No. 63-35468, KOKAI Publication of Japanese Patent Application No. 6-46818, corresponding to EP 0545186, Japanese Patent No. 1681670, Japanese Patent No. 3012253 and KOKAI Publication of Japanese Patent Application No. 2-84168. In these smoking articles, aroma producing element is introduced granular or sheet, between the heat generating element and its end corresponding to the mouth. As the element of aroma production is heated by the heat of the element heat generator, the aroma components vaporize and free.
Se han propuesto, como elemento de producción de aroma, varios materiales moldeados tales como, por ejemplo, un material poroso incombustible y materia prima de tabaco. Sin embargo, el material poroso requiere una energía excesiva para vaporizar o desorber las sustancias aromatizantes absorbidas en su interior, y por consiguiente conlleva el inconveniente de la disminución de la eficiencia de la vaporización o de la desnaturalización térmica de la sustancia aromatizante. Por otra parte, cuando se usa como sustrato un material inflamable tal como un material de tabaco, sustancialmente ocurre la combustión o la descomposición térmica, y por tanto el comportamiento térmico se hace muy inestable, lo que produce un efecto muy desfavorable en la cantidad de aroma suministrado.They have been proposed as an element of production of aroma, various molded materials such as, for example, a fireproof porous material and tobacco raw material. Without However, the porous material requires excessive energy to vaporize or desorb the absorbed flavoring substances in your interior, and therefore entails the inconvenience of decreased efficiency of vaporization or thermal denaturation of the flavoring substance. For other part, when a flammable material such as a substrate is used as a substrate a tobacco material, substantially combustion occurs or the thermal decomposition, and therefore the thermal behavior is it becomes very unstable, which produces a very unfavorable effect on the Amount of aroma supplied.
Además, un artículo para fumar del tipo anteriormente descrito supone un problema básico, como es que la cantidad de aroma producido varía fácilmente, dependiendo del estado de generación de calor del elemento de generación de calor. Como elemento de generación de calor, el que se emplea de un modo más general es un elemento formado usando carbón como materia prima principal. Sin embargo, tal elemento combustible muestra un comportamiento no uniforme en el que la cantidad generadora de calor alcanza su valor máximo durante el periodo desde el encendido hasta la primera mitad del fumado completo, y a continuación la cantidad generadora de calor disminuye gradualmente para llegar eventualmente a extinguirse. Como resultado, la cantidad de aroma liberado por el calor muestra un comportamiento similar y por tanto hay una diferencia significativa creada entre la máxima cantidad y especialmente la cantidad de la última mitad del fumado completo. Por consiguiente, se patentiza que los usuarios sienten un estrés debido al cambio no uniforme en la cantidad de humo y en el aroma durante el fumado, que degrada la sensación de satisfacción.In addition, an article for smoking of the type described above supposes a basic problem, as is that the amount of aroma produced varies easily, depending on the heat generation state of the heat generating element. As an element of heat generation, which is used in a way more general is an element formed using coal as raw material principal. However, such a fuel element shows a non-uniform behavior in which the generating amount of heat reaches its maximum value during the period since the ignition until the first half of complete smoking, and then the heat generating amount gradually decreases to reach eventually to extinguish. As a result, the amount of aroma released by heat shows similar behavior and therefore there is a significant difference created between the maximum amount and especially the amount of the last half of complete smoking. Therefore, it is patented that users feel stress due to the uneven change in the amount of smoke and the aroma during smoking, it degrades the feeling of satisfaction.
Por otra parte, la Publicación KOKAI de Solicitud de Patente Japonesa nº 5-277191 describe un ejemplo de artículo para fumar obtenido estratificando juntos un elemento de combustible y un elemento conformado en placa hecho de un elemento de producción de aroma en una cantidad que corresponde al número predeterminado de bocanadas, con el fin de suministrar una calidad de aroma constante. Sin embargo, debido a la estructura en la que el elemento de combustible y el elemento de producción de aroma de un aislante interpuesto están estratificados uno con el otro, la temperatura del elemento combustible disminuye fácilmente, lo que hace difícil mantener la combustión, con lo que resulta muy posible que el artículo se apague. Además, como el elemento de producción de aroma se calienta en todo momento, la calidad del elemento se deteriora en muchos casos por el calor innecesario. Además, como el artículo requiere una adaptación entre la velocidad a la que se quema el elemento combustible con el tiempo de inhalación, a los usuarios les resulta difícil tomarse los intervalos de inhalación que ellos desean, aumentando así el estrés de los usuarios. A esto hay que añadir que la estructura del artículo es complicada, lo que hace que, en consecuencia, su proceso de elaboración sea difícil.On the other hand, the KOKAI Publication of Japanese Patent Application No. 5-277191 describes an example of a smoking article obtained by stratifying together a fuel element and a plate shaped element made of an element of aroma production in a corresponding amount to the predetermined number of puffs, in order to supply A constant aroma quality. However, due to the structure in which the fuel element and the production element of aroma of an interposed insulator are stratified one with the other, the temperature of the fuel element decreases easily, which makes it difficult to maintain combustion, which is very The item may turn off. In addition, as the element of aroma production is heated at all times, the quality of element is deteriorated in many cases by unnecessary heat. Also, as the article requires an adaptation between speed to which the fuel element burns over time inhalation, users find it difficult to take the inhalation intervals they want, thus increasing stress of the users. To this we must add that the structure of the article is complicated, which makes, consequently, your elaboration process is difficult.
La presente invención se ha realizado en vista de los inconvenientes anteriormente descritos, y tiende a proporcionar un artículo para fumar que tenga una estructura simple, que pueda suministrar el aroma en una cantidad estable en cada bocanada, por el cual los usuarios puedan disfrutar de fumar sin sentir el estrés causado por un cambio irregular en la cantidad de humo y en el aroma durante el fumado.The present invention has been realized in view of the drawbacks described above, and tends to provide a smoking article that has a structure simple, that can supply the aroma in a stable amount in each puff, whereby users can enjoy smoking without feeling the stress caused by an irregular change in the amount of smoke and aroma during smoking.

La presente invención se describirá ahora con detalle.The present invention will now be described with detail.
Un artículo para fumar de acuerdo con la presente invención es un llamado artículo para fumar del tipo sin combustión que no quema un elemento de producción de aroma, y provisto de un elemento de producción de aroma que libera un componente aromatizante cuando el elemento se calienta por el calor generado en el elemento de generación de calor encendido. El elemento de producción de aroma tiene una composición específica y es proporcionado en un elemento cilíndrico hueco. El elemento cilíndrico tiene un elemento de generación de calor en su parte final distal, y su parte final proximal constituye la parte del extremo correspondiente a la boca.An article for smoking according to the The present invention is a so-called smoking article of the type without combustion that does not burn an aroma production element, and provided with an aroma production element that releases a flavoring component when the element is heated by heat generated in the heat generating element on. He aroma production element has a specific composition and It is provided in a hollow cylindrical element. The element cylindrical has a heat generating element in its part distal end, and its proximal end part constitutes the part of the end corresponding to the mouth.
La Fig. 1 es una vista en sección esquemática que muestra la estructura de un artículo para fumar de acuerdo con una realización de la presente invención. Un artículo para fumar 10 mostrado en la Fig. 1 tiene un elemento cilíndrico hueco 11 que constituye el cuerpo principal del artículo para fumar. Un elemento de generación de calor 13 es proporcionado en la parte del extremo distal del elemento cilíndrico 11, y la parte del extremo proximal del elemento cilíndrico 11 constituye la parte del extremo correspondiente a la boca 17. El elemento de producción de aroma 15 de la presente invención es proporcionado adyacente al elemento de generación de calor 13 dentro del elemento cilíndrico 11.Fig. 1 is a schematic sectional view. which shows the structure of an article for smoking according to An embodiment of the present invention. An article for smoking 10 shown in Fig. 1 has a hollow cylindrical element 11 that It is the main body of the smoking article. An element of heat generation 13 is provided at the end part distal of the cylindrical element 11, and the proximal end portion of the cylindrical element 11 constitutes the end part corresponding to mouth 17. The aroma production element 15 of the present invention is provided adjacent to the element of heat generation 13 inside the cylindrical element 11.
El elemento cilíndrico 11 es normalmente de forma cilíndrica circular, y preferentemente está hecho de un material estable térmicamente tal como aluminio o acero inoxidable. Además, con el fin de reducir su capacidad calorífica, el espesor del elemento cilíndrico 11 se hace preferentemente delgado, por ejemplo de 0,03 mm a 0,1 mm. El elemento cilíndrico 11 puede tener un diámetro interior de aproximadamente 7 mm a 8 mm y una longitud de aproximadamente 80 mm a 120 mm, como en el caso de los cigarrillos normales. La totalidad de la superficie exterior del elemento cilíndrico 11 está normalmente envuelta con un elemento aislante del calor 12 para que el elemento cilíndrico pueda sujetarse con los dedos sin problemas.The cylindrical element 11 is normally of circular cylindrical shape, and preferably is made of a thermally stable material such as aluminum or stainless steel. In addition, in order to reduce its heat capacity, the thickness of the cylindrical element 11 is preferably made thin, by example from 0.03 mm to 0.1 mm. The cylindrical element 11 may have an inner diameter of approximately 7 mm to 8 mm and a length from approximately 80 mm to 120 mm, as in the case of normal cigarettes The entire outer surface of the cylindrical element 11 is normally wrapped with an element heat insulator 12 so that the cylindrical element can Hold on with your fingers without problems.
El elemento de producción de aroma 15 empleado para el artículo para fumar de la presente invención se hace de una diversidad de gránulos, cada uno de los cuales contiene de 65 a 93% en peso de un material de relleno inorgánico no poroso, de 1 a 3% en peso de un aglutinante y de 6 a 32% en peso de una sustancia aromatizante, sobre una base en peso seco.The aroma production element 15 used for the smoking article of the present invention it is made of a diversity of granules, each of which contains 65 to 93% by weight of a non-porous inorganic filler material, 1 to 3% by weight of a binder and from 6 to 32% by weight of a substance flavoring, on a dry weight basis.
La sustancia aromatizante incluye, por ejemplo, una sustancia que genera un aerosol (un alcohol, un sacárido, agua), una sustancia que genera solamente un aroma (mentol, cafeína, un extracto natural), cuando es calentada por el calor procedente del elemento de generación de calor quemado, así como tabaco, un extracto de tabaco y una mezcla de los mismos. Como alcohol, por ejemplo, pueden usarse glicerina, propilenglicol o una mezcla de los mismos.The flavoring substance includes, for example, a substance that generates an aerosol (an alcohol, a saccharide, water), a substance that generates only one aroma (menthol, caffeine, a natural extract), when heated by heat from of the burnt heat generation element, as well as tobacco, a tobacco extract and a mixture thereof. Like alcohol, for For example, glycerin, propylene glycol or a mixture of the same.
El material de relleno orgánico sustancialmente no poroso, que es uno de los componentes del elemento de generación de aroma 15, tiene una superficie específica BET de 3 m^{2}/g o menos.The substantially organic filling material non-porous, which is one of the components of the generation element of aroma 15, has a specific BET surface of 3 m 2 / g or less.
Un llamado material poroso que tiene incontables poros extremadamente finos, por ejemplo, carbón activado, materiales cerámicos tales como esferas de alúmina y sílice, o un tamiz molecular tiene la propiedad de captar otras sustancias en su interior por adsorción o absorción. Cuando se intenta tener un aroma liberado desde un artículo para fumar tal como el de la presente invención con una eficiencia elevada, por el calor, no solo se requiere energía térmica para evaporar la sustancia aromatizante sino también es necesaria más energía térmica para desorber la sustancia aromatizante fuera de los poros, si la sustancia aromatizante está atrapada en los poros del sustrato. Así, la eficiencia de la vaporización se reduce y se induce fácilmente una mayor desnaturalización térmica, ya que el material se calienta continuamente dentro de los poros. En la presente invención, la sustancia aromatizante es simplemente retenida en huecos creados cada uno de ellos dentro de los granos de sustrato hechos de material de relleno inorgánico sustancialmente no poroso. Con esta estructura es posible liberar fácilmente el aroma desde el elemento de producción de aroma 15 mediante calor, sin producir el problema antes descrito con el material poroso.A so-called porous material that has countless extremely fine pores, for example, activated carbon, ceramic materials such as alumina and silica spheres, or a molecular sieve has the property of capturing other substances in its interior by adsorption or absorption. When you try to have a scent released from a smoking article such as this invention with high efficiency, because of the heat, not only requires thermal energy to evaporate the flavoring substance but more thermal energy is also needed to desorb the flavoring substance out of the pores, if the substance Flavoring is trapped in the pores of the substrate. So, the vaporization efficiency is reduced and an induction is easily induced greater thermal denaturation, since the material is heated continuously inside the pores. In the present invention, the flavoring substance is simply retained in created holes each of them inside the substrate grains made of substantially non-porous inorganic filler material. With this structure it is possible to easily release the aroma from the element of production of aroma 15 by heat, without causing the problem described above with the porous material.
Es particularmente preferible usar granos de carbonato cálcico que tienen una superficie específica BET de 3 m^{2}/g o menos como material de relleno inorgánico sustancialmente no poroso. Es muy posible que los materiales moldeados granulares estén hechos de materia prima de tabaco, o una materia prima vegetal sustitutoria y su extracto, etc.; sin embargo, en muchos casos tal material causa la combustión o la descomposición térmica por el calor, y por consiguiente el comportamiento térmico se hace inestable. Como resultado, es fácil que la cantidad de aroma suministrado se haga inestable, y es posible causar el problema de la desnaturalización térmica del aroma debida a la porosidad.It is particularly preferable to use grains of calcium carbonate having a specific BET surface of 3 m 2 / g or less as inorganic filler material substantially nonporous. It is very possible that the materials granular molded be made of tobacco raw material, or a substitute vegetable raw material and its extract, etc .; without However, in many cases such material causes combustion or thermal decomposition by heat, and therefore the Thermal behavior becomes unstable. As a result, it is easy that the amount of aroma supplied becomes unstable, and is possible cause the thermal denaturation problem of aroma due to porosity.
Como aglutinante contenido en el elemento de producción de aroma de la presente invención puede usarse celulosa, varios tipos de derivados de celulosa, alginatos, goma guar, goma xantano, goma de algarrobilla y similares. En particular, el uso de metilhidroxietilcelulosa puede mejorar la durabilidad de la sustancia aromatizante y proporcionar un aroma y un sabor excelentes. A medida que se aumenta la cantidad de aglutinante añadido, aumenta la resistencia física del material moldeado, haciendo así posible facilitar su manipulación. Sin embargo, en muchos casos la mayoría de los aglutinantes crean un efecto desfavorable sobre el aroma cuando se calientan a una temperatura elevada. Por consiguiente, siempre y cuando el material pueda ser manipulado sin problemas concretos, la cantidad de aglutinante añadido debe ser preferentemente tan baja como una cantidad en el intervalo de 1 a 3% en peso.As a binder contained in the element of aroma production of the present invention cellulose can be used, various types of cellulose derivatives, alginates, guar gum, gum Xanthan, locust bean gum and the like. In particular, the use of methylhydroxyethyl cellulose can improve the durability of the flavoring substance and provide an aroma and flavor excellent. As the amount of binder increases added, increases the physical strength of the molded material, making it possible to facilitate its handling. However, in many cases most binders create an effect unfavorable about the aroma when heated to a temperature high. Therefore, as long as the material can be handled without concrete problems, the amount of binder added should preferably be as low as an amount in the range of 1 to 3% by weight.
Los gránulos (moldeados o conformados) que constituyen el elemento de producción de aroma de la presente invención pueden prepararse mezclando el material de relleno inorgánico sustancialmente no poroso, el aglutinante y la sustancia aromatizante en las cantidades mencionadas antes, y añadiendo la apropiada cantidad de agua requerida para producir la fuerza de unión del aglutinante. Después, la mezcla se moldea mediante una extrusionadora, una máquina de granular, una máquina para grancear o similar, en un tamaño y una forma predeterminados. Así, los gránulos pueden conformare en pellas, comprimidos, esferas o similares.The granules (molded or shaped) that constitute the aroma production element of the present invention can be prepared by mixing the filler material substantially non-porous inorganic, binder and substance flavoring in the amounts mentioned above, and adding the appropriate amount of water required to produce the force of binder binding. Then, the mixture is molded by extruder, a granular machine, a grancear machine or similar, in a predetermined size and shape. So, the granules can conform into pellets, tablets, spheres or Similar.
Como se muestra en la Fig. 1, se proporciona un elemento 16a resistente al calor y permeable al aire, hecho, por ejemplo, de una malla metálica, entre el elemento de generación de calor 13 y el elemento de producción de aroma 15, de forma que el elemento de producción de aroma 15 no esté en contacto directo con el generador de calor 13.As shown in Fig. 1, a 16a element heat resistant and air permeable, made by example, of a metal mesh, between the generating element of heat 13 and the aroma production element 15, so that the aroma production element 15 is not in direct contact with the heat generator 13.
El elemento de generación de calor 13
proporcionado en la parte del extremo distal del elemento cilíndrico
11 del artículo para fumar de la presente invención puede estar
hecho de un material carbonoso tal como el carbón. El material
carbonoso puede conformarse en la forma que se desee mediante una
extrusionadora, una máquina de grancear o similares. Es preferible
que la forma del material carbonoso sea un cilindro circular. Tal
elemento de generación de calor incluye una vía para el flujo de
aire a través de la cual se introduce aire en el elemento
cilíndrico 11 desde el exterior, pasando por el elemento de
generación de calor 13 por medio de la succión desde el extremo
correspondiente a la boca, y se deja que el aire introducido
calentado por el elemento de generación de calor 13 pase a través
de la vía de flujo de aire creada entre los gránulos 151 del
elemento de producción de aroma 15, haciendo así posible que el
fumador disfrute del componente aromatizante así producido. Tal vía
de flujo de aire puede hacerse de al menos una ranura provista en
una superficie circular externa del material formado del cilindro
carbonoso a lo largo del eje longitudinal del elemento cilíndrico
11 o al menos un orificio pasante hecho a través del material
formado del cilindro carbonoso a lo largo del eje longitudinal del
elemento cilíndrico 11. La Fig. 1 ilustra tales vías de flujo, esto
es, un orificio pasante 131 hecho a través del elemento de
generación de calor 13 en su dirección axial y una diversidad de
orificios pasantes (los orificios pasantes 132 y 133 se muestran en
la Fig. 1) dispuestos alrededor del orificio
pasante
131.The heat generating element 13 provided at the distal end portion of the cylindrical element 11 of the smoking article of the present invention may be made of a carbonaceous material such as coal. The carbonaceous material can be shaped in the manner desired by an extruder, a pelletizing machine or the like. It is preferable that the shape of the carbonaceous material is a circular cylinder. Such heat generating element includes a path for the flow of air through which air is introduced into the cylindrical element 11 from the outside, passing through the heat generating element 13 by means of suction from the end corresponding to the mouth, and the introduced air heated by the heat generating element 13 is allowed to pass through the air flow path created between the granules 151 of the aroma production element 15, thus making it possible for the smoker to enjoy the flavoring component thus produced. Such an air flow path may be made of at least one groove provided on an external circular surface of the material formed of the carbonaceous cylinder along the longitudinal axis of the cylindrical element 11 or at least one through hole made through the material formed of the carbonaceous cylinder along the longitudinal axis of the cylindrical element 11. Fig. 1 illustrates such flow paths, that is, a through hole 131 made through the heat generating element 13 in its axial direction and a variety of through holes (the through holes 132 and 133 are shown in Fig. 1) arranged around the hole
intern 131.
No solo el tipo y la composición del material carbonoso, sino también la forma (la profundidad de cada ranura y el diámetro de cada orificio pasante) y el número de vías de flujo de aire en el elemento de generación de calor 13 tienen efecto sobre las características de combustión tales como el tiempo de encendido del elemento de generación de calor, la velocidad de combustión, la temperatura de combustión y la cantidad de producto creado por la combustión. En particular, en relación con la característica del tiempo de encendido, se requiere que sea el tiempo de encendido que puede esperarse sin que el usuario sienta ninguna diferencia significativa desde el encendido de un cigarrillo ordinario (dentro del plazo de aproximadamente 1 segundo). De acuerdo con la presente invención, se ha encontrado que puede conseguirse un tiempo de encendido para el material carbonoso de aproximadamente 1,5 segundos eligiendo una composición de material carbonoso tal que el conductividad térmica a temperatura ambiente (aproximadamente 22ºC) sea 1,0 W/m\cdotK o menos. Además, de acuerdo con la presente invención, se ha encontrado que cuando el elemento de generación de calor está hecho de una composición de material de carbón que contiene el material de relleno inorgánico sustancialmente no poroso en una cantidad de 15 a 65% en peso (el resto es carbón), la cantidad de carbón se reduce sustancialmente. Así, la cantidad de producto de combustión, especialmente de monóxido de carbono, puede reducirse aún más. Al mismo tiempo, la cantidad de combustión, esto es, el número de bocanadas, puede disminuir, y por consiguiente puede reducirse la cantidad total de producto de combustión. Como material de relleno inorgánico sustancialmente no poroso es particularmente adecuado el carbonato cálcico que tiene una superficie específica BET de 3 m^{2}/g o menos. El calor generado por la combustión del elemento de generación de calor 13 calienta el elemento de producción de aroma 15 dispuesto adyacente al elemento de generación de calor y hace que se vaporice el aroma que se ha de liberar.Not only the type and composition of the material carbonaceous, but also the shape (the depth of each groove and the diameter of each through hole) and the number of flow paths of air in the heat generating element 13 have an effect on the combustion characteristics such as the time of ignition of the heat generating element, the speed of combustion, combustion temperature and product quantity created by combustion. In particular, in relation to the characteristic of the on time, it is required to be the Power-on time that can be expected without the user feeling no significant difference since the ignition of a ordinary cigarette (within approximately 1 period second). In accordance with the present invention, it has been found that an ignition time can be achieved for the material carbonaceous of approximately 1.5 seconds choosing a composition of carbonaceous material such that the thermal conductivity to ambient temperature (approximately 22 ° C) be 1.0 W / mK or less. In addition, according to the present invention, it has been found that when the heat generating element is made of a carbon material composition containing the material of substantially non-porous inorganic filler in an amount of 15 to 65% by weight (the rest is coal), the amount of coal is substantially reduced. Thus, the amount of combustion product, Especially carbon monoxide, it can be further reduced. To the same time, the amount of combustion, that is, the number of puffs, can decrease, and therefore can reduce total amount of combustion product. As filler material substantially non-porous inorganic is particularly suitable the calcium carbonate having a specific BET surface of 3 m 2 / g or less. The heat generated by the combustion of the element of heat generation 13 heats the production element of aroma 15 arranged adjacent to the heat generating element and causes the aroma to be released to vaporize.
Normalmente, el elemento de generación de calor 13 está rodeado por un elemento de inclusión 14 resistente al calor y está introducido y fijado en el elemento cilíndrico 11.Normally, the heat generating element 13 is surrounded by a heat-resistant inclusion element 14 and is inserted and fixed in the cylindrical element 11.
En el elemento cilíndrico 11, puede proporcionarse un elemento de suministro de aroma 18 en un lado aguas abajo del elemento de producción de aroma 15. El elemento de suministro de aroma 18 puede llevar varios tipos de aromas o similares cuando el aroma necesita caracterizarse más añadiendo otros aromas al componente de aroma generado por el elemento de producción de aroma 15, o cuando es preferible que los diversos tipos de aromas no sean expuestos a una temperatura elevada. El elemento de suministro de aroma 18 puede hacerse de tabaco o tabaco reconstituido, o de papel que lleva un aroma, o de un vehículo tal como una tela no tejida, dependiendo de la finalidad. Además, es posible que el elemento de suministro de aroma 18 se proporcione en forma de un material moldeado que contiene un aroma.In the cylindrical element 11, it can provide an aroma supply element 18 on one side downstream of the aroma production element 15. The element of supply of aroma 18 can carry various types of aromas or similar when the aroma needs to be further characterized by adding other aromas to the aroma component generated by the element of aroma production 15, or when it is preferable that the various types of aromas are not exposed to an elevated temperature. He aroma supply element 18 can be made of tobacco or tobacco reconstituted, or of paper bearing an aroma, or of such a vehicle as a non-woven fabric, depending on the purpose. It is also it is possible that the aroma supply element 18 is provided in form of a molded material that contains an aroma.
En la parte del extremo correspondiente a la boca 17, puede proporcionarse un filtro 171 para tabaco, que se emplea de un modo general en la técnica. Para suministrar eficientemente el aroma en una cantidad que pueda ser finalmente fumada por el fumador con respecto a la cantidad de aroma liberado, puede usarse un filtro de baja eficiencia de filtración que tiene una eficiencia de filtración del 20% o menos o un filtro hueco. Además, puede hacerse una diversidad de orificios de ventilación VH en la porción del extremo correspondiente a la boca 17 que perforen a través del elemento de aislamiento del calor 12 y del elemento cilíndrico 11 en las posiciones que se desee (normalmente en una dirección circular de la porción del extremo correspondiente a la boca 17) de acuerdo con las necesidades con el fin de ajustar la magnitud de la succión y la presión de succión.In the part of the end corresponding to the mouth 17, a filter 171 for tobacco can be provided, which is generally employed in the art. To provide efficiently the aroma in an amount that can finally be smoked by the smoker with respect to the amount of aroma released, a low filtration efficiency filter can be used which has a filtration efficiency of 20% or less or a hollow filter. In addition, a variety of VH ventilation holes can be made at the end portion corresponding to the mouth 17 that pierce through the heat insulating element 12 and the element cylindrical 11 in the desired positions (usually in a circular direction of the end portion corresponding to the mouth 17) according to the needs in order to adjust the magnitude of suction and suction pressure.
En la presente invención es posible que el elemento de producción de aroma 15 y el elemento de suministro de aroma 18 estén dispuestos para estar en contacto directo entre sí; sin embargo, es preferible proporcionar una porción hueca 19 entre estos elementos como se muestra en la Fig. 1. En algunos casos, la porción hueca 19 sirve para favorecer el enfriamiento del aerosol o aroma generado a partir del elemento de producción de aroma 15, haciendo así posible reducir la pérdida causada por la condensación del aerosol o aroma en el elemento de suministro de aroma 18 y la parte del extremo correspondiente a la boca 19. El volumen de la porción hueca 19 puede ajustarse arbitrariamente de acuerdo con el propósito. Cuando la porción hueca 19 se proporciona como se describió anteriormente, se proporciona un elemento permeable al aire 16b similar al elemento permeable al aire 16a en un lado aguas abajo del elemento de producción de aroma 15 de manera que los gránulos 151 no se muevan.In the present invention it is possible that the aroma production element 15 and the supply element of aroma 18 are arranged to be in direct contact with each other; however, it is preferable to provide a hollow portion 19 between these elements as shown in Fig. 1. In some cases, the hollow portion 19 serves to favor the cooling of the aerosol or aroma generated from the aroma production element 15, thus making it possible to reduce the loss caused by condensation of the spray or aroma in the aroma supply element 18 and the part of the end corresponding to the mouth 19. The volume of the hollow portion 19 may be arbitrarily adjusted in accordance with the purpose. When the hollow portion 19 is provided as described above, a permeable element is provided to the air 16b similar to the air permeable element 16a on a water side below the aroma production element 15 so that the 151 granules do not move.
En la presente invención, es preferible que los gránulos 151 estén introducidos en el elemento cilíndrico 11 en su estado de empaquetamiento más estrecho. Si los gránulos 151 se ponen sueltos en el elemento cilíndrico, se distribuyen irregularmente en el elemento cuando se están usando y así las vías de fluido formadas entre los gránulos 151 se hacen irregulares, deteriorando así la uniformidad de la cantidad de aroma suministrado. Por esta razón, es preferible que los gránulos rellenen el elemento cilíndrico en su densidad de empaquetamiento más estrecha para que pueda mantenerse el estado de relleno inicial. Se entiende que el empaquetamiento más estrecho es un estado en el que los gránulos son introducidos densamente en el elemento mediante vibración o golpeteo, etc.In the present invention, it is preferable that granules 151 are inserted in the cylindrical element 11 in its narrower packing state. If the granules 151 are put loose in the cylindrical element, they are distributed irregularly in the element when they are being used and thus the fluid paths formed between the granules 151 they become irregular, thus deteriorating the uniformity of the amount of aroma supplied. For this reason, it is preferable that the granules fill the cylindrical element in its narrower packing density so it can be maintained The initial fill status. It is understood that the packaging more narrow is a state in which the granules are introduced densely in the element by vibration or tapping, etc.
Aquí, se ha encontrado que es preferible que la longitud rellena (L) de los gránulos 151 introducidos en el estado de empaquetamiento más estrecho y el diámetro interno (D) del elemento cilíndrico 11 se ajusten de forma que la relación entre ellos (L/D) sea de 2 a 4. Cuando la relación es menor de 2, hay una tendencia tal que el comportamiento de la producción del componente de aroma a partir del elemento de producción de aroma 15 es fácilmente afectada por el patrón de generación de calor del elemento de generación de calor 13. Por otra parte, cuando la relación es mayor que 4, hay una tendencia tal que la cantidad de aroma suministrado desciende fácilmente debido a la condensación y la deposición del componente en el elemento de producción de aroma 15. Así, hay una tendencia a que se deteriore la uniformidad del suministro de aroma. Por consiguiente, cuando el diámetro interior del elemento cilíndrico 11 es aproximadamente 7 a 8 mm como en el caso de los cigarrillos ordinarios, la longitud rellena (L) se ajusta preferentemente en un intervalo de aproximadamente 14 a 32 mm. Además, se ha encontrado también que el tamaño de los gránulos 151 se ajusta preferentemente de forma que la relación entre el diámetro mayor (d) y el diámetro interior (D) del elemento cilíndrico 11 (D/d) sea de 3,5 a 16, o más preferentemente de 4 a 15. Cuando la relación es menor que 4, la capacidad calorífica por gránulo 151 disminuye y por consiguiente existe la tendencia a que disminuya la cantidad de aroma suministrado en el estado inicial del acto de fumar. Por otra parte, cuando la relación es mayor que 15, la resistencia a la succión aumenta y por tanto la succión tiende a hacerse difícil. Por consiguiente, cuando el diámetro interior (D) del elemento cilíndrico 11 es aproximadamente de 7 a 8 mm, como en el caso de los cigarrillos corrientes, el diámetro mayor de los gránulos 151 debe ajustarse preferentemente en un margen de aproximadamente 2,0 a 0,5 mm. El diámetro mayor de los gránulos se define como el diámetro más grande en la dirección axial o en la dirección radial.Here, it has been found that it is preferable that the filled length (L) of the granules 151 introduced in the state narrower packing and internal diameter (D) of cylindrical element 11 fit so that the relationship between them (L / D) be from 2 to 4. When the ratio is less than 2, there is a trend such that the component's production behavior of aroma from the aroma production element 15 is easily affected by the heat generation pattern of the heat generating element 13. On the other hand, when the ratio is greater than 4, there is a trend such that the amount of Scent supplied drops easily due to condensation and the deposition of the component in the aroma production element 15. Thus, there is a tendency for the uniformity of the aroma supply Therefore, when the inside diameter of the cylindrical element 11 is approximately 7 to 8 mm as in the case of ordinary cigarettes, the length filled (L) is preferably fits in a range of about 14 to 32 mm In addition, it has also been found that the size of the granules 151 is preferably adjusted so that the relationship between the larger diameter (d) and inner diameter (D) of the element cylindrical 11 (D / d) is 3.5 to 16, or more preferably 4 to 15. When the ratio is less than 4, the heat capacity by granule 151 decreases and therefore there is a tendency to decrease the amount of aroma supplied in the initial state of the act of smoking. On the other hand, when the relationship is greater than 15, the suction resistance increases and therefore the suction It tends to become difficult. Therefore, when the diameter inside (D) of the cylindrical element 11 is approximately 7 to 8 mm, as in the case of ordinary cigarettes, the diameter greater than the granules 151 should preferably be adjusted in a margin of approximately 2.0 to 0.5 mm. The largest diameter of the granules are defined as the largest diameter in the axial direction or in the radial direction.
La presente invención se describirá ahora presentando ejemplos reales; sin embargo, la invención no debe limitarse a los ejemplos que siguen.The present invention will now be described. presenting real examples; however, the invention must not limit yourself to the examples that follow.
Ejemplo Experimental 1Experimental Example one
La Fig. 2A y la Fig. 2B muestran los resultados del análisis por DSC (calorimetría diferencial de barrido) para el caso en el que se empleó carbonato cálcico que tiene una superficie específica BET de 1 m^{2}/g como material de relleno inorgánico no poroso, y se mezcló con sustancia aromatizante (Fig. 2A), y para el caso en el que se empleó alúmina que tiene una superficie específica BET de 120 m^{2}/g como material de relleno inorgánico poroso y se mezcló con la misma sustancia aromatizante a la misma relación (Fig. 2B). Cuando se usa el material de relleno inorgánico no poroso, el pico endotérmico producido por la vaporización de la sustancia aromatizante aparece solamente una vez, como se muestra en la Fig. 2A. Por otra parte, cuando se usa el material de relleno inorgánico poroso, aparece un pico endotérmico (pico endotérmico (1)) y otro pico endotérmico (pico endotérmico (2)) en una zona de temperatura más alta, como se muestra en la Fig. 2B. Los resultados indican que se requiere más energía para vaporizar la sustancia aromatizante adsorbida en el material poroso. Por consiguiente, a partir de los resultados puede entenderse que el uso de un material no poroso es significativamente ventajoso.Fig. 2A and Fig. 2B show the results of the analysis by DSC (differential scanning calorimetry) for case in which calcium carbonate having a surface was used BET specific of 1 m 2 / g as inorganic filler material non-porous, and mixed with flavoring substance (Fig. 2A), and for the case in which alumina was used that has a surface BET specific of 120 m2 / g as inorganic filler material porous and mixed with the same flavoring substance to it relationship (Fig. 2B). When inorganic filler material is used non-porous, the endothermic peak produced by the vaporization of the flavoring substance appears only once, as shown in Fig. 2A. On the other hand, when the filling material is used inorganic porous, an endothermic peak appears (endothermic peak (1)) and another endothermic peak (endothermic peak (2)) in an area of higher temperature, as shown in Fig. 2B. The results indicate that more energy is required to vaporize the substance flavoring adsorbed on the porous material. Therefore, to from the results it can be understood that the use of a material Non-porous is significantly advantageous.

Un artículo para fumar similar al del Ejemplo 1, excepto que el contenido de carbonato cálcico en el elemento de generación de calor se ajustó en 40% en peso, y el artículo para fumar así preparado fue sometido a un proceso de fumado similar. Los resultados indicaron que la cantidad de monóxido de carbono generada se redujo al 55% de la del Ejemplo 1.A smoking article similar to that of Example 1, except that the calcium carbonate content in the element of heat generation was set at 40% by weight, and the item for Smoking so prepared was subjected to a similar smoking process. The results indicated that the amount of carbon monoxide generated was reduced to 55% of that of Example 1.
Ejemplo Comparativo 1Comparative Example one
En el caso en que el elemento de producción de aroma es débil al calor y tiene una propiedad o forma tales que se quema fácilmente, el estado relleno varía debido a la combustión y la cantidad de aroma generado aumenta bruscamente por el calor de combustión. Por consiguiente, su comportamiento se hace incluso más irregular o no uniforme que el comportamiento de generación de calor del propio elemento de generación de calor. Aquí, se preparó un material de producción de aroma a partir de medio de hoja picada hecho de pulpa y material basado en tabaco, como se describe en la publicación de solicitud de patente japonesa KOKAI nº 6-46818, y una sustancia aromatizante (por ejemplo glicerina) contenida en el medio en un 40% en peso, y rellenado para tener una longitud de aproximadamente 30 mm. Así pues, se fabricó un artículo para fumar similar al del Ejemplo 2. La Fig. 6 muestra los resultados de la medida de la cantidad de sustancia aromatizante recogida en cada bocanada. La cantidad total de material de aroma recogido fue aproximadamente 13 mg, lo que no era muy diferente de la del Ejemplo 1, mientras que el índice de uniformidad era tan bajo como 0,31. Además, el artículo para fumar se desmontó después de fumarlo y se examinó. Se encontró que algo de la hoja picada se había incinerado y perdido por combustión.In the case where the production element of aroma is weak to heat and has a property or form such that it burns easily, the filled state varies due to combustion and the amount of aroma generated increases sharply due to the heat of combustion. Consequently, their behavior becomes even more irregular or non-uniform that the behavior of generating heat of the heat generation element itself. Here, he prepared an aroma production material from chopped leaf medium made of pulp and tobacco-based material, as described in the Japanese patent application publication KOKAI No. 6-46818, and a flavoring substance (for example glycerin) contained in the medium by 40% by weight, and filled to have a length of approximately 30 mm. So it was manufactured a smoking article similar to that of Example 2. Fig. 6 shows the results of the measurement of the amount of flavoring substance Pickup at each puff. The total amount of aroma material collected was approximately 13 mg, which was not very different from that of Example 1, while the uniformity index was so low as 0.31. In addition, the smoking article was disassembled after of smoking it and it was examined. It was found that some of the chopped leaf was He had cremated and lost from combustion.
