Description

氣溶膠產生物件    Aerosol-generating object   

本發明有關一種包括氣溶膠形成基材和可燃性熱源的氣溶膠產生物件，以及一種用於形成這種氣溶膠產生物件的方法。 The present invention relates to an aerosol-generating article including an aerosol-forming substrate and a flammable heat source, and a method for forming such an aerosol-generating article.

已有先前技術提出若干種加熱菸草而非燃燒菸草之氣溶膠產生物件。此類「加熱式」氣溶膠產生物件之一目的在於：降低習知菸草中由於菸草之燃燒及熱解所產生之已知有害煙組份種類。在一種已知的加熱式氣溶膠產生物件類型中，氣溶膠係藉由從可燃性熱源將熱傳遞到鄰近可燃性熱源的氣溶膠形成基材來產生。在氣溶膠產生期間，來自可燃性熱源之熱傳遞使氣溶膠形成基材中釋放出揮發性化合物，且該揮發性化合物挾帶在經氣溶膠產生物件吸入之空氣中。所釋出的化合物冷卻時，其會凝結而形成供使用者吸入的氣溶膠。 The prior art has proposed several aerosol-generating articles that heat tobacco rather than burn tobacco. One of the purposes of such "heated" aerosol-generating articles is to reduce the known types of harmful smoke components in conventional tobacco due to tobacco combustion and pyrolysis. In one known type of heated aerosol-generating article, aerosols are generated by transferring heat from a flammable heat source to an aerosol-forming substrate adjacent to the flammable heat source. During the generation of aerosol, heat transfer from a flammable heat source causes volatile compounds to be released from the aerosol-forming substrate, and the volatile compounds are carried in the air inhaled by the aerosol-generating object. When the released compound cools, it condenses to form an aerosol for inhalation by the user.

用於加熱的氣溶膠產生物件中的可燃性熱源之燃燒溫度不應太高以避免在使用加熱的氣溶膠產生物件期間氣溶膠形成基材的燃燒或熱降解。然而，可燃性 熱源的燃燒溫度應該夠高以產生足夠的熱來從氣溶膠形成基材釋放足夠的揮發性化合物，以產生令人可接受的氣溶膠，特別是在初期抽吸期間。 The combustion temperature of the flammable heat source in the heated aerosol-generating article should not be too high to avoid burning or thermal degradation of the aerosol-forming substrate during the use of the heated aerosol-generating article. However, the combustion temperature of the flammable heat source should be high enough to generate enough heat to release enough volatile compounds from the aerosol-forming substrate to produce an acceptable aerosol, especially during the initial puff.

在本技術領域中，已提出多種用於加熱的氣溶膠產生物件的可燃性熱源。用於加熱的氣溶膠產生物件中的可燃性熱源之燃燒溫度通常介於約600℃至800℃之間。 In the art, a variety of flammable heat sources for heating aerosol-generating objects have been proposed. The combustion temperature of the flammable heat source in the aerosol-generating article used for heating is usually between about 600 ° C and 800 ° C.

已知將一絕緣件圍繞包覆於加熱的氣溶膠產生物件的可燃性熱源的外圍，以降低該加熱的氣溶膠產生物件的表面溫度。然而，已發現這種絕緣件在可燃性熱源燃燒期間會降低可燃性熱源的溫度，可能因此降低熱源加熱氣溶膠形成基材來產生氣溶膠的有效性。當一絕緣件實質上延伸可燃性熱源的長度時，這種效應特別顯著。這種絕緣件也會抑制可燃性熱源的持續燃燒，使得可燃性熱源的燃燒時長被降低。 It is known to surround an outer periphery of a flammable heat source of a heated aerosol-generating object with an insulating member to reduce the surface temperature of the heated aerosol-generating object. However, it has been found that such insulators reduce the temperature of the flammable heat source during the combustion of the flammable heat source, which may therefore reduce the effectiveness of the heat source to heat the aerosol-forming substrate to generate the aerosol. This effect is particularly significant when an insulator extends substantially the length of the flammable heat source. Such an insulator also inhibits the continuous combustion of the flammable heat source, so that the burning time of the flammable heat source is reduced.

期望能提供一種氣溶膠產生物件，其在接近熱源處具有一降低的表面溫度，並具有可接受的外觀，且其可以直接和可靠的方式組合。並且期望能提供一種氣溶膠產生物件，其在抽吸期間的初期和末期皆能產生令人可接受的氣溶膠。 It is desirable to provide an aerosol-generating article that has a reduced surface temperature near a heat source and has an acceptable appearance, and that can be combined in a direct and reliable manner. It is also desirable to provide an aerosol-generating article that can produce acceptable aerosols at the beginning and end of the suction period.

根據本發明的第一態樣，提供一種氣溶膠產生物件，其包括氣溶膠形成基材、可燃性熱源，以及包圍可燃性熱源之長度的至少一部分之至少一層陶瓷紙。至少一層陶瓷紙包含纖維素衍生物。 According to a first aspect of the present invention, there is provided an aerosol-generating article including an aerosol-forming substrate, a flammable heat source, and at least one layer of ceramic paper surrounding at least a portion of a length of the flammable heat source. At least one layer of ceramic paper contains cellulose derivatives.

在使用時，可燃性熱源可由一外部熱源點燃，例如一打火機，且可開始燃燒。燃燒的熱源可加熱氣溶膠形成基材，使氣溶膠形成基材的揮發性化合物氣化。在一使用者吸吮氣溶膠產生物件時，空氣可被吸入氣溶膠產生物件並與來自加熱的氣溶膠形成基材的蒸氣混合，以形成一氣溶膠。氣溶膠可從氣溶膠產生物件被吸出並傳送到使用者供使用者吸入。 In use, the flammable heat source may be ignited by an external heat source, such as a lighter, and may begin to burn. The combustion heat source can heat the aerosol-forming substrate to vaporize the volatile compounds of the aerosol-forming substrate. When a user sucks the aerosol-generating object, air can be drawn into the aerosol-generating object and mixed with the vapor from the heated aerosol-forming substrate to form an aerosol. The aerosol can be aspirated from the aerosol-generating article and delivered to the user for inhalation.

所述包圍可燃性熱源的長度的至少一部分之至少一層陶瓷紙可絕緣可燃性熱源。這可降低在可燃性熱源處的氣溶膠產生物件的表面溫度。所述至少一層陶瓷紙也可允許足夠的空氣通過該層，使得可燃性熱源的燃燒可實質上不受阻礙。 The at least one layer of ceramic paper surrounding at least a portion of the length of the flammable heat source can insulate the flammable heat source. This reduces the surface temperature of the aerosol-generating object at the source of the flammable heat. The at least one layer of ceramic paper may also allow sufficient air to pass through the layer so that the combustion of the flammable heat source may be substantially unhindered.

如本文所用，「生物持久性」一詞意指完整的纖維維持在人類呼吸系統的肺部及胸膜(胸腔)中的時長。 As used herein, the term "biological persistence" means the length of time that intact fibers are maintained in the lungs and pleura (thorax) of the human respiratory system.

用於測量生物持久性之適合的短期測試包括短期吸入實驗。一示範短期間吸入實驗包含將囓齒動物每日暴露在既定纖維類型的已知濃度下6小時共5天，隨後定期處死以確定肺纖維負擔。已在下列文獻中描述這種程序：Bernstein,D.M.,C.Morscheidt,H.-G.Grimm,P.Thevenaz，及U.Teichert 1996。使用吸入生物持久性模型之可溶性纖維的評估，九種纖維比較。(Evaluation of soluble fibers using the inhalation biopersistence model,a nine-fiber comparison)吸入毒藥學(Inhalation Toxicol.)8(4)：345-385。測量生物持久性的替代適合之短期測試包括氣管內滴注實驗，其包括通過氣管內滴入方式給予囓齒動物生理鹽水中(含已知量的纖維)並定期處死以確定肺纖維負荷。 Suitable short-term tests for measuring biological persistence include short-term inhalation experiments. A demonstration short-term inhalation experiment involves exposing rodents daily to known concentrations of a given fiber type for 6 hours for 5 days, followed by periodic sacrifice to determine the pulmonary fiber burden. Such procedures have been described in the following documents: Bernstein, D.M., C. Morscheidt, H.-G. Grimm, P. Thevenaz, and U. Teichert 1996. Evaluation of soluble fibers using inhaled biopersistence model, comparison of nine fibers. (Evaluation of soluble fibers using the inhalation biopersistence model, a nine-fiber comparison) Inhalation Toxicol. 8 (4): 345-385. Alternative short-term tests for measuring biological persistence include an intratracheal instillation experiment, which involves administering physiological saline (containing a known amount of fiber) to rodents by intratracheal instillation and sacrifice periodically to determine lung fiber load.

短期吸入法及氣管內滴入法的結果可表示為加權清除半衰期(WT1/2)或自肺部清除90%纖維所需的時間(T90)。 The results of short-term inhalation and intratracheal instillation can be expressed as the weighted clearance half-life (WT1 / 2) or the time required to clear 90% of the fibers from the lungs (T90).

如果短期生物持久吸入測試顯示超過20微米之纖維具有10天或更少的加權半壽命或短期生物持久氣管內滴入測試顯示超過20微米之纖維具有40天或 更少的加權半壽命則纖維可視為具有「低生物持久性」或為「低生物持久」，如在1997年12月5日的歐盟委員會指令97/69/EC的註釋Q中所提出。如果在2mg的細纖維懸浮液(纖維具有5μm的長度、小於3μm的直徑以及超過3：1的長度與直徑比(WHO纖維))之氣管內滴入後的半壽命不超過40天，則纖維也可視為具有「低生物持久性」或為「低生物持久」，如克減自指令97/69/EC的在1999年10月26日針對德國通知關於礦物棉的國家規定之歐盟委員會決定1999/836/EC之注釋Q2中所提出。 Fibers are visible if short-term biopersistent inhalation tests show a fiber with a weighted half-life of 10 days or less over 20 micrometers or short-term biopersistent tracheal instillation tests show a fiber with a weighted half-life of 40 days or less To be "low biopersistent" or "low biopersistent", as proposed in Note Q of the European Commission Directive 97/69 / EC of 5 December 1997. If the half-life after instillation in a trachea of 2mg of fine fiber suspension (fiber has a length of 5 μm, a diameter less than 3 μm, and a length to diameter ratio exceeding 3: 1 (WHO fiber)) does not exceed 40 days, the fiber It can also be regarded as having "low biological persistence" or "low biological persistence", such as the European Commission decision 1999, which was derogated from Directive 97/69 / EC, informing Germany of the national regulations on mineral wool on October 26, 1999 Proposed in Note Q2 of / 836 / EC.

具有低生物持久性的材料可透過一種機制從人類呼吸系統移除或清除。從呼吸系統移除材料的一示範機制為物理移位，如通過粘液纖毛運輸。從呼吸系統移除材料的另一示範機制為化學溶解。如果在呼吸系統的溶劑中材料的可溶性夠高的話，材料可視為「生物可溶解」。 Materials with low biological persistence can be removed or cleared from the human respiratory system through a mechanism. An exemplary mechanism for removing material from the respiratory system is physical displacement, such as transport through mucous cilia. Another exemplary mechanism for removing material from the respiratory system is chemical dissolution. If the solubility of the material in the solvents of the respiratory system is high enough, the material can be considered "biosoluble".

在一些實施例中，陶瓷紙可包含生物可溶纖維。在一些特定實施例中，陶瓷紙的纖維材料可由生物可溶纖維構成。 In some embodiments, the ceramic paper may include biosoluble fibers. In some specific embodiments, the fibrous material of the ceramic paper may be composed of biosoluble fibers.

如本文中所用，「生物可溶解」一詞用來描述可溶解於生物系統中的材料；尤其，用來描述可溶解在人類呼吸系統中的材料。人類呼吸系統中之材料的生物溶解度可與材料在水中的溶解度明顯不同。如本文中所用，生物可溶纖維被視為低生物持久纖維。 As used herein, the term "biosoluble" is used to describe materials that are soluble in biological systems; in particular, it is used to describe materials that are soluble in the human respiratory system. The biological solubility of materials in the human respiratory system can differ significantly from the solubility of materials in water. As used herein, biosoluble fibers are considered low-bio-persistent fibers.

如本文中所用，如果體外靜態溶解度測試指 示物質的至少0.1g溶解在100ml的人類呼吸系統溶劑中的話，則物質被視為「生物可溶的」。類似地，如果少於0.1g的材料溶解在100ml之人類呼吸系統溶劑中，則物質可被視為生物不可溶的。 As used herein, a substance is considered "biosoluble" if at least 0.1 g of the substance in vitro static solubility test indicates that it is dissolved in 100 ml of a human respiratory system solvent. Similarly, a substance can be considered bio-insoluble if less than 0.1 g of material is dissolved in 100 ml of a human respiratory system solvent.

適合的體外靜態溶解度測試包含將待測試物質的取樣在37℃的溫度暴露在適合的溶劑24小時。24小時過後，可藉由判斷溶解-流體組成或剩餘取樣的重量來測量溶解度。例如，使用溶解流體的電感耦合等離子體光譜法的元素分析可用於計算溶解流體中已溶解取樣的總質量。 A suitable in vitro static solubility test involves exposing a sample of the substance to be tested to a suitable solvent at a temperature of 37 ° C for 24 hours. After 24 hours, solubility can be measured by determining the dissolution-fluid composition or the weight of the remaining sample. For example, elemental analysis using inductively coupled plasma spectroscopy with dissolved fluids can be used to calculate the total mass of dissolved samples in the dissolved fluid.

在體外靜態溶解度測試中用作人類呼吸系統溶劑的合適溶劑包括生理鹽水溶液和人類呼吸系統溶劑的替代物，例如已知的模擬肺液(SLF)。已知合適的SLF包括具有約4.5的pH的人造溶酶體液(ALF)，類似於其中肺中的肺泡和間質巨噬細胞吞噬後吸入顆粒將接觸的流體，以及具有約7.4的pH的甘伯(Gamble)溶液，類似於肺內深部的間質液。 Suitable solvents for use as a human respiratory system solvent in an in vitro static solubility test include physiological saline solutions and alternatives to human respiratory system solvents, such as known simulated lung fluid (SLF). Suitable SLFs are known to include artificial lysosomal fluid (ALF) with a pH of about 4.5, similar to fluids in which the particles will be contacted by inhaled alveolar and interstitial macrophages in the lung, and glycine with a pH of about 7.4 Gamble solution, similar to interstitial fluid deep in the lungs.

如本文所用，如果體外動態溶解度測試表明物質表現出在人的呼吸系統溶劑中每小時每平方公分至少150納克的溶出速率常數(ng/cm2‧小時)的話，則物質也可被認為是「生物可溶的」。 As used herein, a substance can also be considered to be a substance if its in vitro dynamic solubility test shows a dissolution rate constant (ng / cm 2 ‧ hours) of at least 150 nanograms per square centimeter per hour in human respiratory system solvents. "Biosoluble".

合適的體外動態溶解度測試包括在測試物質取樣上緩慢地流過合適的溶劑並測量纖維隨時間的溶解。進行該測試很長一段時間，比如至少三星期，以判斷取樣的溶解長期下來是否均勻。更詳言之，將合適的 溶劑緩慢地泵送到已標準化至其表面積的纖維取樣上，使得新鮮溶液總是呈現給取樣。特別合適的體外動態溶解度測試包括在1000小時中以37℃的溫度使合適的溶劑以每小時5ml的速率流過要測試的取樣。收集溶液並分析從纖維取樣中浸出的元素濃度。在測試期間重複收集溶液數次，比如每週兩次，以判斷取樣的溶解經時是否均勻或不變。 A suitable in vitro dynamic solubility test involves slowly flowing a suitable solvent over a sample of test substance and measuring the dissolution of the fiber over time. The test is performed for a long period of time, such as at least three weeks, to determine whether the dissolution of the sample is uniform over time. In more detail, a suitable solvent is slowly pumped onto a fiber sample normalized to its surface area so that fresh solution is always present for sampling. A particularly suitable in vitro dynamic solubility test involves flowing a suitable solvent through a sample to be tested at a rate of 5 ml per hour at a temperature of 37 ° C for 1000 hours. The solution was collected and analyzed for the concentration of elements leaching from the fiber samples. Repeat the collection of the solution several times during the test, such as twice a week, to determine whether the dissolution of the sample is uniform or constant over time.

可藉由判斷溶解-流體組成或剩餘取樣的重量來測量溶解度。例如，使用溶解流體的電感耦合等離子體光譜法的元素分析可用於計算在特定時間間隔溶解流體中已溶解取樣的總質量。由於已知取樣的表面積和溶劑的流速，並且從溶解測量值判斷浸出物濃度，這些值可用來透過已知方法判斷溶解率。溶解率可表示為每小時每平方公分納克(ng/cm2hr)。 Solubility can be measured by judging the dissolution-fluid composition or the weight of the remaining samples. For example, elemental analysis using inductively coupled plasma spectroscopy of dissolved fluids can be used to calculate the total mass of dissolved samples in the dissolved fluid at specific time intervals. Since the sampled surface area and solvent flow rate are known, and the leachate concentration is determined from the dissolution measurements, these values can be used to determine the dissolution rate by known methods. The dissolution rate can be expressed as nanograms per square centimeter (ng / cm 2 hr) per hour.

在體外動態溶解度測試中用作人類呼吸系統溶劑的合適溶劑包括生理鹽水溶液和SLF，如上針對體外靜態溶解度測試所述。 Suitable solvents for use as solvents in the human respiratory system in in vitro dynamic solubility tests include physiological saline solutions and SLF, as described above for in vitro static solubility tests.

Adhesive-free ceramic papers are also suitable, such as Rescor 300 BL from Final Advanced Materials or adhesive-free biosoluble fiber paper from DL-Thermal. Some adhesive-free ceramic papers containing at least one of the following may be suitable: biosoluble fibers, low bio-persistent fibers, and fibers containing at least one of the following: silicon dioxide, calcium oxide, and magnesium oxide. Some binderless ceramic papers containing alkaline earth silicate fibers may be suitable.

在一些實施例中，陶瓷紙可包含生物可溶纖維及低生物持久纖維之一或更多者。為生物可溶及低生物持久的至少一者之合適的材料範例包括，但不限於，二氧化矽、氧化鈣、及氧化鎂。為生物可溶及低生物持久的至少一者之特別合適的材料包括鹼土矽酸鹽類。 In some embodiments, the ceramic paper may include one or more of bio-soluble fibers and low bio-persistent fibers. Examples of suitable materials that are at least one of bio-soluble and low-bio-durable include, but are not limited to, silicon dioxide, calcium oxide, and magnesium oxide. Particularly suitable materials that are at least one of biosoluble and low biopersistent include alkaline earth silicates.

陶瓷紙可具有低導熱係數。換句話說，陶瓷紙可以是良好的熱絕緣體。例如，陶瓷紙在約23℃的溫度下可具有介於約0.5到2W/mK之間的導熱係數。此一低導熱係數特別顯現在陶瓷紙包含編造或非編造的纖維性陶瓷材料。這可能是因為由纖維性陶瓷材料所構成的陶瓷紙能減少傳導性的熱傳遞的相對開放的高度多孔狀結構。 Ceramic paper may have a low thermal conductivity. In other words, ceramic paper can be a good thermal insulator. For example, ceramic paper may have a thermal conductivity between about 0.5 and 2 W / mK at a temperature of about 23 ° C. This low thermal conductivity is particularly manifested in ceramic paper containing fabricated or non-woven fibrous ceramic materials. This may be due to the relatively open, highly porous structure of ceramic paper composed of fibrous ceramic materials that reduces conductive heat transfer.

陶瓷紙可具有對空氣的高透氣性。這可能是因為其相對開放的高度多孔狀結構。所述至少一層陶瓷紙對空氣可為充分可穿透以使可燃性熱源能實質上不受阻礙地燃燒。例如，所述至少一層陶瓷紙可具有對空氣 為大於約4000(cm3/(min*cm2)的透氣性。 Ceramic paper may have high air permeability. This may be due to its relatively open, highly porous structure. The at least one layer of ceramic paper may be sufficiently permeable to air to enable the combustible heat source to burn substantially unhindered. For example, the at least one layer of ceramic paper may have air permeability to air greater than about 4000 (cm 3 / (min * cm 2 ).

所述至少一層陶瓷紙包圍可燃性熱源的長度的至少一部分。本發明之至少一層陶瓷紙可實質上包圍可燃性熱源的全長。這能使氣溶膠產生物件得利於陶瓷紙的隔絕特性，以在使用期間降低在接近熱源處的表面溫度，並得利於陶瓷紙對空氣的透氣性而使足夠的周遭空氣能抵達可燃性熱源，供可燃性熱源實質上不受阻礙地點燃及燃燒。 The at least one layer of ceramic paper surrounds at least a portion of the length of the flammable heat source. The at least one layer of ceramic paper of the present invention may substantially cover the entire length of the flammable heat source. This enables the aerosol-generating objects to benefit the insulation properties of the ceramic paper, to reduce the surface temperature near the heat source during use, and to facilitate the air permeability of the ceramic paper, so that sufficient ambient air can reach the flammable heat source. The flammable heat source ignites and burns substantially unhindered.

陶瓷紙可具有有利的機械性質。例如，因為陶瓷材料的補強效果，特別是有陶瓷纖維時，陶瓷紙可以是可彎折且可加工的。陶瓷紙可以具有機械加工性，其有助於形成圍繞熱源的長度的至少一部分的陶瓷紙層。 Ceramic paper can have advantageous mechanical properties. For example, because of the reinforcing effect of ceramic materials, especially when ceramic fibers are present, ceramic paper can be bendable and processable. The ceramic paper may have a machinability that helps to form a ceramic paper layer around at least a portion of the length of the heat source.

如本文中所用，術語「層」係用以描述大致符合可燃性熱源的形狀之材料體。所述至少一層陶瓷紙可以是於配置來包圍熱源之任何合適類型的層。合適的層的類型尤其包括包裹物和塗覆層。如本文中所用，「塗覆層」一詞用以描述覆蓋並黏著於熱源的材料層。 As used herein, the term "layer" is used to describe a body of material that generally conforms to the shape of a flammable heat source. The at least one layer of ceramic paper may be any suitable type of layer configured to surround the heat source. Suitable types of layers include inter alia wraps and coatings.

For example, the at least one layer of ceramic paper may surround a flammable heat source about half the length. The at least one layer of ceramic paper may surround more than half the length of the flammable heat source. The at least one layer of ceramic paper may surround a length of the combustible heat source between about 60% and about 100%. The at least one layer of ceramic paper may surround the flammable heat source by at least about 70% of its length. The at least one layer of ceramic paper may surround the flammable heat source by at least about 80% of its length. The at least one layer of ceramic paper may surround the flammable heat source by at least about 90% of its length. The at least one layer of ceramic paper of the present invention may substantially surround the length of the flammable heat source.

所述至少一層陶瓷紙可包圍可燃性熱源的全長。如本文中所用，「長度」一詞用以描述氣溶膠產生物件之縱向方向上之氣溶膠產生物件的一組件或一部分的尺寸。 The at least one layer of ceramic paper may surround the entire length of the flammable heat source. As used herein, the term "length" is used to describe the size of a component or part of an aerosol-generating object in the longitudinal direction of the aerosol-generating object.

Advantageously, the at least one layer of ceramic paper surrounding the aerosol-forming substrate can reduce the surface temperature of the aerosol-generating article at the aerosol-forming substrate.

所述至少一層陶瓷紙可在可燃性熱源的下游端包圍可燃性熱源。這有利於降低氣溶膠產生物件在可燃性熱源之部分(其在氣溶膠產生物件正常運作期間最接近使用者)的表面溫度。 The at least one layer of ceramic paper may surround the flammable heat source at a downstream end of the flammable heat source. This is beneficial to lower the surface temperature of the aerosol-generating article at the portion of the flammable heat source that is closest to the user during normal operation of the aerosol-generating article.

所述至少一層陶瓷紙可在可燃性熱源的上游端包圍可燃性熱源。 The at least one layer of ceramic paper may surround the flammable heat source at an upstream end of the flammable heat source.

所述至少一層陶瓷紙可在上游端和下游端包圍可燃性熱源。 The at least one layer of ceramic paper may surround a flammable heat source at an upstream end and a downstream end.

可燃性熱源未被覆蓋的部分在此可稱為「裸露」部分。可提供本發明之至少一層陶瓷紙以覆蓋或包圍可燃性熱源的「裸露」或未覆蓋部分。 The portion of the flammable heat source that is not covered may be referred to herein as the "naked" portion. At least one layer of ceramic paper of the present invention may be provided to cover or surround the "naked" or uncovered portion of the flammable heat source.

在一些實施例中，可由至少一額外層在上游 端包圍可燃性熱源的一部分。所述至少一額外層可為捲菸紙層。在這些實施例中，可燃性熱源的上游部分為裸露部分。換言之，可燃性熱源的上游部分並未被至少一額外層所覆蓋。在一些實施例中，所述至少一層陶瓷紙可包圍可燃性熱源的上游部分。所述至少一層陶瓷紙可從包圍可燃性熱源的上游端之所述至少一額外層的上游端包圍可燃性熱源至可燃性熱源的下游端處或周圍。因此，在這些實施例中，可藉由在下游端的至少一額外層及在上游端的至少一層陶瓷紙之組合實質上沿可燃性熱源的長度包圍可燃性熱源。在一些實施例中，至少一層陶瓷紙及至少一額外層可沿可燃性熱源的長度重疊。 In some embodiments, a portion of the flammable heat source may be surrounded at the upstream end by at least one additional layer. The at least one additional layer may be a cigarette paper layer. In these embodiments, the upstream portion of the flammable heat source is a bare portion. In other words, the upstream portion of the flammable heat source is not covered by at least one additional layer. In some embodiments, the at least one layer of ceramic paper may surround an upstream portion of a flammable heat source. The at least one layer of ceramic paper may surround the flammable heat source from the upstream end of the at least one additional layer surrounding the flammable heat source to or around the downstream end of the flammable heat source. Therefore, in these embodiments, the combustible heat source may be surrounded substantially by the length of the combustible heat source by a combination of at least one additional layer at the downstream end and at least one layer of ceramic paper at the upstream end. In some embodiments, at least one layer of ceramic paper and at least one additional layer may overlap along the length of the flammable heat source.

可燃性熱源、氣溶膠形成基材和至少一層陶瓷紙可配置成實質上防止或抑制氣溶膠形成基材的溫度在可燃性熱源燃燒期間超過約375℃。例如，可燃性熱源、氣溶膠形成基材和至少一層陶瓷紙之形狀、大小及配置可被構造成實質上防止或抑制氣溶膠形成基材的溫度在可燃性熱源燃燒期間超過約375℃。這可保持氣溶膠形成基材的完整性。例如，若氣溶膠形成基材包含一或多個氣溶膠形成劑，氣溶膠形成劑可能在溫度超過約375℃時遭受熱解。在甚至更高的溫度下，且當氣溶膠形成基材包含例如煙草時，煙草可能會燃燒。 The flammable heat source, the aerosol-forming substrate, and the at least one layer of ceramic paper may be configured to substantially prevent or inhibit the temperature of the aerosol-forming substrate from exceeding about 375 ° C during the combustion of the flammable heat source. For example, the shape, size, and configuration of the flammable heat source, the aerosol-forming substrate, and the at least one layer of ceramic paper may be configured to substantially prevent or inhibit the temperature of the aerosol-forming substrate from exceeding about 375 ° C during the combustion of the flammable heat source. This maintains the integrity of the aerosol-forming substrate. For example, if the aerosol-forming substrate contains one or more aerosol-forming agents, the aerosol-forming agent may be subject to pyrolysis at temperatures exceeding about 375 ° C. At even higher temperatures, and when the aerosol-forming substrate contains, for example, tobacco, tobacco may burn.

可燃性熱源、氣溶膠形成基材和至少一層陶瓷紙可構造成使得在可燃性熱源燃燒期間，氣溶膠形成基材在距離氣溶膠形成基材近端面2mm的溫度在至少約6分鐘的期間為至少約100℃。 The flammable heat source, the aerosol-forming substrate, and at least one layer of ceramic paper may be configured such that during the combustion of the flammable heat source, the aerosol-forming substrate is at a temperature of 2 mm from the proximal end surface of the aerosol-forming substrate for a period of at least about 6 minutes At least about 100 ° C.

如本文中所用，術語「近」和「遠」係用以描述根據本發明的氣溶膠產生物驗的組件或組件部分的相對位置。氣溶膠產生物件的組件的近端是指該組件最接近氣溶膠產生物件的嘴端的一端，而氣溶膠產生物件的組件的遠端是指該組件最遠離氣溶膠產生物件的嘴端的一端。典型地，可燃性熱源設置於氣溶膠產生物件的遠端。 As used herein, the terms "near" and "far" are used to describe the relative position of a component or component part of an aerosol-generating object according to the invention. The proximal end of the component of the aerosol-generating object refers to the end of the component closest to the mouth end of the aerosol-generating object, and the distal end of the component of the aerosol-generating object refers to the end of the component farthest from the mouth end of the aerosol-generating object.

如本文中所用，「氣溶膠」一詞用以描述開孔泡沫。氣溶膠可為中孔性(mesoporous)。「中孔性」一詞是指含有直徑介於約2奈米至約50奈米範圍內的孔之材料。氣溶膠可包含互連結構網絡，該互連結構網絡可為奈米結構。氣溶膠可呈現約50%或更多的孔隙度。氣溶膠可呈現約90%或更多的孔隙度。可藉由從傳統膠移除液體成份來形成氣溶膠。傳統的膠應理解為意指固體分散在液體中的半固體膠體懸浮液。 As used herein, the term "aerosol" is used to describe an open-cell foam. The aerosol may be mesoporous. The term "mesoporosity" refers to materials containing pores having a diameter ranging from about 2 nanometers to about 50 nanometers. The aerosol may include a network of interconnected structures, which may be a nanostructure. Aerosols can exhibit porosity of about 50% or more. Aerosols can exhibit porosity of about 90% or more. Aerosols can be formed by removing liquid components from traditional gums. Traditional gums are understood to mean semi-solid colloidal suspensions in which solids are dispersed in a liquid.

氣溶膠典型具有非常低的導熱係數。不希望受限於理論，氣溶膠中的傳導性熱傳遞因其高孔隙度而受到抑制，而氣溶膠中的對流性熱傳遞因孔的小直徑受到抑制。孔的小直徑限制空氣移動通過氣溶膠。 Aerosols typically have very low thermal conductivity. Without wishing to be bound by theory, conductive heat transfer in aerosols is suppressed due to their high porosity, while convective heat transfer in aerosols is suppressed due to the small diameter of the pores. The small diameter of the holes restricts air movement through the aerosol.

如本文中所用，「纖維強化氣溶膠」一詞是指包含以纖維材料強化的氣溶膠基質的複合材料。 As used herein, the term "fiber-reinforced aerosol" refers to a composite material comprising an aerosol matrix reinforced with a fiber material.

氣溶膠產生物件2的組件被包覆在一層香煙紙7中。香煙紙7包圍導熱元件9，但未延伸超過導熱元件9的遠端，在可燃性熱源3的遠端部分之上。 The components of the aerosol-generating article 2 are covered in a layer of cigarette paper 7. The cigarette paper 7 surrounds the heat-conducting element 9 but does not extend beyond the distal end of the heat-conducting element 9 above the distal portion of the flammable heat source 3.

根據本發明，氣溶膠產生物件2更包括一層陶瓷紙5。陶瓷紙5實質上包圍可燃性熱源3的長度及香煙紙7、導熱元件9和氣溶膠形成基材4的遠端部分。換句話說，該層陶瓷紙5為在氣溶膠產生物件2的遠端的徑向外層。 According to the invention, the aerosol-generating article 2 further comprises a layer of ceramic paper 5. The ceramic paper 5 substantially surrounds the length of the flammable heat source 3 and the distal end portion of the cigarette paper 7, the heat conducting element 9, and the aerosol-forming substrate 4. In other words, this layer of ceramic paper 5 is a radially outer layer at the distal end of the aerosol-generating article 2.

該層陶瓷紙5包含介於約60重量%至約70重量%之間的二氧化矽；介於約16重量%至約22重量%之間的氧化鈣；及介於約12重量%至約19重量%之間的氧化鎂。該層陶瓷紙5亦包含氧化鋁。該層陶瓷紙5亦 包含纖維素衍生物黏合劑。纖維素衍生物黏合劑包含以8重量%的濃度分散於水中的CMC。 The layer of ceramic paper 5 comprises between about 60% by weight and about 70% by weight of silica; between about 16% by weight and about 22% by weight of calcium oxide; and between about 12% by weight and about 19% by weight of magnesium oxide. This layer of ceramic paper 5 also contains alumina. This layer of ceramic paper 5 also contains a cellulose derivative binder. The cellulose derivative binder contains CMC dispersed in water at a concentration of 8% by weight.

複數個空氣入口8配置於氣溶膠形成基材4以允許周遭空氣被吸入氣溶膠產生物件2。空氣入口8包括複數個穿孔，其通過香煙紙7和其下層包圍氣溶膠形成基材4的濾嘴塞19。空氣入口8配置在氣溶膠形成基材4的近端面和遠端面之間。 The plurality of air inlets 8 are disposed on the aerosol-forming substrate 4 to allow ambient air to be drawn into the aerosol-generating article 2. The air inlet 8 includes a plurality of perforations which pass through the cigarette paper 7 and a filter plug 19 of the aerosol-forming substrate 4 surrounding the aerosol-forming substrate 4. The air inlet 8 is arranged between the proximal end surface and the distal end surface of the aerosol-forming substrate 4.

當使用者抽吸氣溶膠產生物件2的嘴件10時，周遭空氣可通過空氣入口8被吸入氣溶膠產生物件2中。被吸進入氣溶膠產生物件2中的空氣可沿著氣溶膠產生物件2的氣流路徑流動，從空氣入口8通過氣溶膠形成基材4、傳遞元件11、冷卻元件12和間隔元件13到達嘴件10，並從嘴件10流出到使用者供吸入。氣流通過氣溶膠產生物件2的大致方向係以箭頭指示。 When the user sucks the mouthpiece 10 of the aerosol-generating article 2, the surrounding air can be drawn into the aerosol-generating article 2 through the air inlet 8. The air sucked into the aerosol-generating object 2 can flow along the airflow path of the aerosol-generating object 2 and reach the mouthpiece from the air inlet 8 through the aerosol-forming substrate 4, the transmission element 11, the cooling element 12, and the spacer element 13. 10, and flows from the mouthpiece 10 to the user for inhalation. The general direction of the airflow through the aerosol-generating object 2 is indicated by arrows.

在使用中，使用者可藉由將可燃性熱源3曝露於外部熱源，例如打火機，來點燃可燃性熱源3。可燃性熱源3可點燃並燃燒，且熱可從可燃性熱源3透過導熱部件6和導熱元件9的傳導而傳送到氣溶膠形成基材4。加熱的氣溶膠形成基材4的揮發性成分可以被氣化。使用者可抽吸氣溶膠產生物件2的嘴件10，使周遭空氣通過空氣入口8被吸入氣溶膠產生物件2的氣流路徑中。來自加熱的氣溶膠形成基材4的蒸氣可被夾帶在抽吸通過氣溶膠形成基材4的空氣中，並可與該空氣一起被吸向嘴件10。當蒸氣被吸向嘴件10時，該蒸氣可冷卻以形成氣溶膠。氣溶膠可從嘴件10被吸出並被傳送 到使用者供吸入。 In use, the user can ignite the flammable heat source 3 by exposing the flammable heat source 3 to an external heat source, such as a lighter. The flammable heat source 3 can be ignited and burned, and heat can be transferred from the flammable heat source 3 to the aerosol-forming substrate 4 through conduction of the thermally conductive member 6 and the thermally conductive element 9. The volatile components of the heated aerosol-forming substrate 4 may be vaporized. The user can suck the mouthpiece 10 of the aerosol-generating article 2 so that the surrounding air is drawn into the airflow path of the aerosol-generating article 2 through the air inlet 8. Vapor from the heated aerosol-forming substrate 4 may be entrained in the air sucked through the aerosol-forming substrate 4 and may be sucked toward the mouthpiece 10 together with the air. When the vapor is drawn toward the mouthpiece 10, the vapor may be cooled to form an aerosol. The aerosol can be aspirated from the mouthpiece 10 and delivered to a user for inhalation.

應理解的是，實質上為不透氣的第一阻隔物6抑制空氣被抽吸通過可燃性熱源3及進入氣溶膠形成基材4中。因此，第一阻隔物6實質上將氣溶膠產生物件2的氣流路徑與可燃性熱源3隔離。 It should be understood that the substantially air-impermeable first barrier 6 prevents air from being drawn through the combustible heat source 3 and into the aerosol-forming substrate 4. Therefore, the first barrier 6 substantially isolates the airflow path of the aerosol-generating object 2 from the flammable heat source 3.

在此實施例中，該層陶瓷紙5在氣溶膠形成基材4的遠端的一小部分上延伸。因此，該層陶瓷紙5與空氣入口8間隔開來。此一間隔實質上將陶瓷紙5與空氣入口8隔離，使得被抽吸通過氣溶膠產生物件2的氣流路徑的空氣不會發生與該層陶瓷紙5接觸。 In this embodiment, the layer of ceramic paper 5 extends over a small portion of the distal end of the aerosol-forming substrate 4. Therefore, this layer of ceramic paper 5 is spaced from the air inlet 8. This interval substantially isolates the ceramic paper 5 from the air inlet 8 so that the air sucked through the air flow path of the aerosol-generating object 2 does not come into contact with the layer of ceramic paper 5.

應可理解的是，在一些實施例中，該層陶瓷紙可在空氣入口的近處。在這些實施例中，陶瓷紙在空氣入口近處的部分可以一實質上對纖維及顆粒為不可穿透的材料所塗覆。這可實質上將該層陶瓷紙在空氣入口近處的部分隔離，使得被抽吸通過氣溶膠產生物件的氣流路徑的空氣不會與該層陶瓷紙的接觸。 It should be understood that in some embodiments, this layer of ceramic paper may be near the air inlet. In these embodiments, the portion of the ceramic paper near the air inlet may be coated with a material that is substantially impermeable to fibers and particles. This can substantially isolate the portion of the ceramic paper layer near the air inlet, so that the air sucked through the air flow path of the aerosol-generating object will not contact the ceramic paper layer.

收集實驗數據來決定各種類似於圖1所示之氣溶膠產生物件2的氣溶膠產生物件之可燃性熱源和氣溶膠形成基材在可燃性熱源燃燒期間的溫度。每一種受測的氣溶膠產生物件包含一不同的材料層，其實質上包圍可燃性熱源的長度。在實驗中，於氣溶膠產生物件中形成2mm深的孔；其中兩個孔形成於可燃性熱源中在圖1中所示之位置T1及T2，而其中一個孔形成在氣溶膠形成基材中在圖1中所示之位置T3。在每一個孔中***一熱電偶以測量在每一位置的溫度。特別是，實驗數 據是針對包含實質上包圍可燃性熱源的長度的一層陶瓷紙以及不包含實質上包圍可燃性熱源的長度的材料層之氣溶膠產生物件所收集。圖2-4顯示各種氣溶膠產生物件在三個不同位置的溫度對時間之實驗測量圖。 The experimental data is collected to determine the temperature of the flammable heat source and the aerosol-forming substrate of the aerosol-generating object similar to the aerosol-generating object 2 shown in FIG. Each aerosol-generating object tested includes a different layer of material that substantially surrounds the length of the flammable heat source. In the experiment, holes 2 mm deep were formed in the aerosol-generating article; two of the holes were formed in the flammable heat source at positions T 1 and T 2 shown in FIG. 1, and one of the holes was formed in the aerosol-forming substrate The position T 3 in the material is shown in FIG. 1. Insert a thermocouple in each hole to measure the temperature at each location. In particular, the experimental data was collected for an aerosol-generating article including a layer of ceramic paper having a length substantially surrounding the flammable heat source and a material layer not including a length substantially surrounding the flammable heat source. Figures 2-4 show experimental measurements of temperature versus time for various aerosol-generating objects at three different locations.

圖2顯示在距離可燃性熱源的遠端2mm的位置測得的溫度，該位置相當於圖1所示之位置T1。換句話說，圖2顯示在可燃性熱源之遠端的溫度。 FIG. 2 shows the temperature measured at a position 2 mm from the far end of the flammable heat source, which corresponds to the position T 1 shown in FIG. 1 . In other words, Figure 2 shows the temperature at the far end of the flammable heat source.

圖3顯示在距離可燃性熱源的遠端5mm的位置測得的溫度，該位置相當於圖1所示之位置T2。換句話說，圖3顯示在沿著可燃性熱源的長度約一半的位置的溫度。 FIG. 3 shows the temperature measured at a position 5 mm from the far end of the flammable heat source, which corresponds to the position T 2 shown in FIG. 1. In other words, FIG. 3 shows the temperature at a position about half the length of the flammable heat source.

圖4顯示在距離可燃性熱源的遠端11mm的位置測得的溫度，該位置相當於圖1所示之位置T3。換句話說，圖4顯示在氣溶膠形成基材的遠端處的溫度。 FIG. 4 shows the temperature measured at a position 11 mm from the far end of the flammable heat source, which corresponds to the position T 3 shown in FIG. 1. In other words, FIG. 4 shows the temperature at the distal end of the aerosol-forming substrate.

所有溫度曲線是使用電子溫度探針以***氣溶膠產生物件的相應組件中約2mm深處的方式來測量。 All temperature profiles were measured using an electronic temperature probe, inserted approximately 2 mm deep into the corresponding component of the aerosol-producing object.

在圖2、3和4中，標記為20的「SMAR」線顯示不具有「裸」可燃性熱源的的氣溶膠產生物件的溫度曲線。換言之，「SMAR」線22線顯示不具有實質上包圍可燃性熱源的長度的材料層的氣溶膠產生物件的溫度曲線。 In Figures 2, 3 and 4, the "SMAR" line labeled 20 shows the temperature profile of an aerosol-generating article without a "naked" flammable heat source. In other words, the "SMAR" line 22 shows a temperature curve of an aerosol-generating article having no material layer having a length substantially surrounding the flammable heat source.

在圖2、3和4中，標記為21的「陶瓷紙1」線顯示具有實質上包圍可燃性熱源的長度的一層陶瓷紙之氣溶膠產生物件的溫度曲線。在「陶瓷紙1」測試中實質上包圍可燃性熱源的長度的陶瓷紙為可從Morgan Advanced Materials公司購得之Superwool® Plus纖維。 In Figures 2, 3, and 4, the "ceramic paper 1" line labeled 21 shows the temperature profile of an aerosol-generating article with a layer of ceramic paper having a length that substantially surrounds a flammable heat source. The length of ceramic paper that substantially surrounded the flammable heat source in the "ceramic paper 1" test was Superwool® Plus fiber available from Morgan Advanced Materials.

在圖2、3和4中，標記為22的「陶瓷紙2」線顯示具有實質上包圍可燃性熱源的長度的一層陶瓷紙的氣溶膠產生物件的溫度曲線。在「陶瓷紙2」測試中實質上包圍可燃性熱源的長度的陶瓷紙為可從Ningbo Firewheel Thermal Insulation & Sealing Co.公司購得之CFP陶瓷纖維紙。 In Figures 2, 3, and 4, the "ceramic paper 2" line labeled 22 shows the temperature profile of an aerosol-generating article with a layer of ceramic paper having a length that substantially surrounds a flammable heat source. The ceramic paper of a length substantially surrounding the flammable heat source in the "ceramic paper 2" test was a CFP ceramic fiber paper commercially available from Ningbo Firewheel Thermal Insulation & Sealing Co.

在圖2、3和4中，標記為23的[玻璃紙」線顯示具有實質上包圍可燃性熱源的長度的一層陶瓷紙的氣溶膠產生物件的溫度曲線。在「玻璃紙」測試中實質上包圍可燃性熱源的長度的陶瓷紙為包含玻璃纖維的陶瓷紙。 In FIGS. 2, 3, and 4, the [cellophane] line labeled 23 shows the temperature profile of an aerosol-generating article having a layer of ceramic paper having a length that substantially surrounds a flammable heat source. In the "cellophane" test, a ceramic paper having a length substantially surrounding a flammable heat source is a ceramic paper containing glass fibers.

期望具有實質上包圍可燃性熱源的長度之材料層的氣溶膠產生物件的溫度曲線呈現實質上類似於或超過具有裸可燃性熱源(亦即，不具有實質上包圍可燃性熱源的長度的材料層)的氣溶膠產生物件的溫度曲線20。當可燃性熱源呈現與裸可燃性熱源類似或更大的溫度時，這表示實質上包圍可燃性熱源的長度之材料層並沒有實質上抑制可燃性熱源的燃燒。 It is desirable that the temperature profile of an aerosol-generating article having a layer of material that substantially surrounds a flammable heat source exhibit a temperature profile that is substantially similar to or exceeds that of a bare flammable heat source (that is, a material layer that does not have a length that substantially surrounds the flammable heat source). The aerosol produces a temperature profile 20 of the object. When the flammable heat source exhibits a temperature similar to or greater than that of the bare flammable heat source, this means that the material layer that substantially surrounds the length of the flammable heat source does not substantially inhibit the combustion of the flammable heat source.

另人驚訝的是，如圖2、3和4所示，在可燃性熱源絕大部分的燃燒期間，具有實質上包圍可燃性熱源的長度的一層陶瓷紙的氣溶膠產生物件的溫度曲線21、22、23在氣溶膠產生物件的三個位置上皆實質上類似於不具有實質上包圍可燃性熱源的長度的材料層的氣溶膠產生物件的溫度曲線20。此外，在氣溶膠產生經歷 的某些期間，具有實質上包圍可燃性熱源的長度的一層陶瓷紙的氣溶膠產生物件的溫度曲線21及22實際上超過不具有實質上包圍可燃性熱源的長度的材料層的氣溶膠產生物件的溫度曲線20。 Surprisingly, as shown in Figs. 2, 3 and 4, during the combustion of most of the flammable heat source, the temperature profile of the aerosol-generating article having a layer of ceramic paper substantially surrounding the length of the flammable heat source, 21, 22 and 23 are substantially similar to the temperature profile 20 of the aerosol-generating object at three positions of the aerosol-generating object without a material layer having a length substantially surrounding the flammable heat source. In addition, during certain periods of aerosol generation, the temperature profiles 21 and 22 of the aerosol-generating article having a layer of ceramic paper that substantially surrounds the length of the flammable heat source actually exceed the temperature curve 21 and 22 that do not have a length that substantially surrounds the flammable heat source. The aerosol of the material layer produces a temperature profile 20 of the article.

此另人驚訝的結果表示提供至少一層實質上包圍可燃性熱源的長度的陶瓷紙有利地實質上不阻礙可燃性熱源的燃燒。實際上，提供該層陶瓷紙可在可燃性熱源燃燒期間提高可燃性熱源的溫度。 This surprising result indicates that providing at least one layer of ceramic paper of a length substantially surrounding the flammable heat source advantageously does not substantially hinder the combustion of the flammable heat source. In fact, providing this layer of ceramic paper can increase the temperature of the flammable heat source during the combustion of the flammable heat source.

圖5顯示如上述般針對三種特定氣溶膠產生物件所收集的進一步實驗資料的圖。與圖4類似，圖5顯示在氣溶膠形成基材的遠端之溫度，在距離可燃性熱源的遠端11mm的位置所測得，該位置相當於圖1所示之位置T3。所有溫度曲線同樣是使用電子溫度探針以***氣溶膠產生物件的相應組件中約2mm深處的方式來測量。 Figure 5 shows a graph of further experimental data collected for the three specific aerosol-generating objects as described above. Similar to FIG. 4, FIG. 5 shows the temperature at the far end of the aerosol-forming substrate, measured at a position 11 mm from the far end of the flammable heat source, which is equivalent to the position T 3 shown in FIG. 1. All temperature curves are also measured using an electronic temperature probe, inserted approximately 2 mm deep into the corresponding component of the aerosol-producing object.

在圖5中，標記為30的「SMAR」線顯示具有「裸」可燃性熱源之氣溶膠產生物件的溫度曲線。換言之，「SMAR」線22線顯示不具有實質上包圍可燃性熱源的長度的材料層的氣溶膠產生物件的溫度曲線。 In FIG. 5, the “SMAR” line labeled 30 shows a temperature curve of an aerosol-generating article having a “naked” flammable heat source. In other words, the "SMAR" line 22 shows a temperature curve of an aerosol-generating article having no material layer having a length substantially surrounding the flammable heat source.

在圖5中，標記為31的“玻璃紙”線顯示具有實質上包圍可燃性熱源的長度之一層陶瓷紙的氣溶膠產生物件的溫度曲線。在「玻璃紙」測試中實質上包圍可燃性熱源的長度的陶瓷紙為包含玻璃纖維的陶瓷紙。包含玻璃纖維的陶瓷紙具有約1mm的厚度及約5.5mm的長度，從可燃性熱源的遠端延伸於可燃性熱源的全長及 氣溶膠形成基材的遠端上方。 In FIG. 5, a “cellophane” line labeled 31 shows a temperature curve of an aerosol-generating article having a length of a layer of ceramic paper substantially surrounding a flammable heat source. In the "cellophane" test, a ceramic paper having a length substantially surrounding a flammable heat source is a ceramic paper containing glass fibers. The ceramic paper containing glass fiber has a thickness of about 1 mm and a length of about 5.5 mm, and extends from the distal end of the flammable heat source to the full length of the flammable heat source and above the distal end of the aerosol-forming substrate.

在圖5中，標記為32的“生物可溶解纖維”線顯示具有實質上包圍可燃性熱源的長度之一層陶瓷紙的氣溶膠產生物件的溫度曲線。在「生物可溶解纖維」測試中實質上包圍可燃性熱源的長度的陶瓷紙為可從Morgan Advanced Materials公司購得之Superwool® Plus纖維。Superwool® Plus纖維包含生物可溶解鹼土矽酸鹽纖維。包含生物可溶解纖維的陶瓷紙具有約0.5mm的厚度及約5.5mm的長度，從可燃性熱源的遠端延伸於可燃性熱源的全長及氣溶膠形成基材的遠端上方。 In FIG. 5, the “biodissolvable fiber” line labeled 32 shows a temperature curve of an aerosol-generating article having a layer of ceramic paper having a length substantially surrounding a flammable heat source. The length of ceramic paper that substantially surrounded the flammable heat source in the "biodissolvable fiber" test was Superwool® Plus fiber available from Morgan Advanced Materials. Superwool® Plus fibers contain bio-soluble alkaline earth silicate fibers. The ceramic paper containing biodissolvable fibers has a thickness of about 0.5 mm and a length of about 5.5 mm, extending from the distal end of the flammable heat source to the full length of the flammable heat source and above the distal end of the aerosol-forming substrate.

另人驚訝的是，如圖5所示，發現到在約200秒時期後具有包含生物可溶解鹼土矽酸鹽纖維之陶瓷紙層的氣溶膠產生物件之溫度曲線32表示出比在200秒時期後不具有實質上包圍可燃性熱源的長度的材料層的氣溶膠產生物件的溫度曲線30及具有包含玻璃纖維的陶瓷紙層的氣溶膠產生物件的溫度曲線31更高的溫度。 Surprisingly, as shown in FIG. 5, it was found that the temperature curve 32 of an aerosol-generating article having a ceramic paper layer containing a bio-soluble alkaline earth silicate fiber after a period of about 200 seconds indicates that The temperature profile 30 of the aerosol-generating article which does not have a length of material layer substantially surrounding the flammable heat source and the temperature profile 31 of the aerosol-generating article having a ceramic paper layer containing glass fiber are higher.

此令人驚訝的結果表示可藉由具有實質上包圍可燃性熱源的長度並包含生物可溶解鹼土矽酸鹽纖維之陶瓷紙層的氣溶膠產生物件增加抽煙時間，即使與具有包含玻璃纖維的陶瓷紙層的氣溶膠產生物件相比。藉由在點燃熱源後將根據本發明的氣溶膠產生物件置於惠特曼濾紙上來觀察其效應以測試它們。例如，氣溶膠產生物件是24小時控制在約23℃±3℃和相對溼度55%±5%的條件下。使用一電子打火機點燃條件受控的氣溶膠產生物件，並讓其持續燃燒2分鐘。2分鐘後，將 氣溶膠產生物件置到一疊惠特曼濾紙上10分鐘。10分鐘後，檢驗惠特曼濾紙。可觀察到具有實質上包圍可燃性熱源的長度的陶瓷紙層的氣溶膠產生物件在任何惠特曼濾紙上不會產生任何孔洞，而在最上層濾紙中產生一小褐變區域。這結果顯示，設置實質上包圍可燃性熱源的長度的該層陶瓷紙降低了在接近熱源附近的表面溫度。 This surprising result indicates that smoking time can be increased by an aerosol-generating article having a length that substantially surrounds a flammable heat source and containing a ceramic paper layer of bio-soluble alkaline earth silicate fibers, even with ceramics containing glass fibers. The paper layer is compared to aerosol-generating objects. They were tested by observing their effects by placing aerosol-generating objects according to the invention on Whitman filter paper after igniting the heat source. For example, the aerosol-generating article is controlled under conditions of about 23 ° C ± 3 ° C and relative humidity of 55% ± 5% for 24 hours. An electronic lighter is used to ignite the aerosol-generating object under controlled conditions and let it burn for 2 minutes. After 2 minutes, the aerosol-generating article was placed on a stack of Whitman filter paper for 10 minutes. After 10 minutes, inspect the Whitman filter paper. It can be observed that an aerosol-generating article having a length of a ceramic paper layer substantially surrounding a flammable heat source does not create any holes in any Whitman filter paper, but creates a small browning region in the uppermost filter paper. This result shows that the provision of the layer of ceramic paper having a length substantially surrounding the flammable heat source reduces the surface temperature near the heat source.

圖6中顯示根據本發明之一種氣溶膠產生物件的第二實施例的示意圖。氣溶膠產生物件102實質上類似於圖1所示的氣溶膠產生物件2。氣溶膠產生物件102包括可燃性熱源103、氣溶膠形成基材104、一層陶瓷紙105和一層菸草紙107，其以與圖1所示的氣溶膠產生物件2的相對應組件類似方式配置。然而，可燃性熱源103為一非盲式熱源。非盲式熱源103包括一碳質材料的環形體115，其具有延伸於遠端面和近端面之間的通道116。通道116形成部分通過氣溶膠產生物件的氣流路徑，且使空氣能從氣溶膠產生物件的近端被抽吸通過可燃性熱源103到氣溶膠形成基材104。陶瓷紙層105與通過氣溶膠產生物件102的氣流路徑間隔開，使得被抽吸通過氣流路徑的空氣不會與陶瓷紙層105接觸。 FIG. 6 is a schematic diagram showing a second embodiment of an aerosol-generating article according to the present invention. The aerosol-generating article 102 is substantially similar to the aerosol-generating article 2 shown in FIG. 1. The aerosol-generating object 102 includes a flammable heat source 103, an aerosol-forming substrate 104, a layer of ceramic paper 105, and a layer of tobacco paper 107, which are configured in a similar manner to corresponding components of the aerosol-generating object 2 shown in FIG. However, the combustible heat source 103 is a non-blind heat source. The non-blind heat source 103 includes an annular body 115 of carbonaceous material, which has a channel 116 extending between a distal surface and a proximal surface. The channel 116 forms an air flow path that partially passes through the aerosol-generating object, and enables air to be sucked from the proximal end of the aerosol-generating object through the combustible heat source 103 to the aerosol-forming substrate 104. The ceramic paper layer 105 is spaced from the airflow path through the aerosol-generating object 102 so that the air drawn through the airflow path does not contact the ceramic paper layer 105.

一不可燃且實質上不透氣的第一阻隔物106係配置在可燃性熱源103的近端和氣溶膠形成基材104的遠端之間，類似於有關上述圖1中所述的第一阻隔物6。然而，不同於上述的第一阻隔物6，第一阻隔物106 包括對準通道116的開孔120，以使空氣能從通道116通過到氣溶膠形成基材104。 A non-combustible and substantially air-impermeable first barrier 106 is disposed between the proximal end of the flammable heat source 103 and the distal end of the aerosol-forming substrate 104, similar to the first barrier described in FIG. 1 above. 6. However, unlike the first barrier 6 described above, the first barrier 106 includes an opening 120 aligned with the channel 116 so that air can pass from the channel 116 to the aerosol-forming substrate 104.

一不可燃且實質上不透氣的第二阻隔物117被塗覆在通道116的內表面上。第二阻隔物117將通過通道116的空氣與可燃性熱源103以及可燃性熱源的燃燒產物隔開。 A non-combustible and substantially air-impermeable second barrier 117 is coated on the inner surface of the channel 116. The second barrier 117 separates the air passing through the passage 116 from the combustible heat source 103 and the combustion products of the combustible heat source.

因為可燃性熱源103是非盲式熱源，氣溶膠產生物件102不包括配置在氣溶膠形成基材104處的空氣入口。當使用者抽吸氣溶膠產生物件102的嘴件時，周遭空氣可通過穿過熱源103的通道116進入氣溶膠產生物件102中。被抽吸進入氣溶膠產生物件102的空氣可沿著氣溶膠產生物件102的氣流路徑流動，經由通道116通過氣溶膠形成基材104、傳遞元件、冷卻元件和間隔元件到達嘴件，並從嘴件流出到使用者供吸入。氣流通過氣溶膠產生物件102的大致方向係以箭頭指示。 Because the combustible heat source 103 is a non-blind heat source, the aerosol-generating article 102 does not include an air inlet disposed at the aerosol-forming substrate 104. When the user sucks the mouthpiece of the aerosol-generating object 102, the surrounding air can enter the aerosol-generating object 102 through the passage 116 passing through the heat source 103. The air sucked into the aerosol-generating object 102 can flow along the airflow path of the aerosol-generating object 102, pass through the channel 116 through the aerosol-forming substrate 104, the transmission element, the cooling element and the spacer element to reach the mouthpiece, and from the mouth The pieces flow out to the user for inhalation. The general direction of airflow through the aerosol-generating object 102 is indicated by arrows.

應理解的是，在某些實施例中，除了通過可燃性熱源的空氣通道，也可在氣溶膠產生物件中提供其他空氣入口。 It should be understood that in some embodiments, in addition to the air passage through the flammable heat source, other air inlets may be provided in the aerosol-generating article.

上述特定實施例意在舉例說明本發明。然而，本發明之其它實施例可在不偏離本發明請求項所定義的範疇下實施，且應理解上述的具體實施例並非是限制性的。 The specific embodiments described above are intended to illustrate the invention.
