The invention relates to a smoking article comprising an agent that modifies the negative effect of aerosol-generating agents, resembles tobacco smoke, and preferably contains no more than the minimum amount of products of incomplete combustion or pyrolysis.
The aim of the invention is to improve the taste sensations during smoking.
FIG. 1 shows a smoking article in the form of a cigarette; figure 2 - carbon fuel cell, cross section.15
The smoking article contains a carbon fuel cell 1 at the end of the combustion, and on the opposite side a separate means creating an aerosol disposed between the fuel cell 20 and the mouthpiece 2, having a substrate 3 and an aerosol-forming substance containing an agent selected from the group consisting of levulinic acid, a carbohydrate etheracetate, 25 carbohydrate ether levulinat or mixtures thereof.
The carbohydrate eLira acetate is selected from the group consisting of glucose pentaacetate, sucrose octaacetate and fructose pentaacetate. thirty
In addition, the agent included in the composition of the aerosol-forming substance is contained in an amount that provides smoke during the smoking process with a pH from 4.0 to 7.5.35
The substrate may be made of a substance selected from the group consisting of carbon and alumina, and the ratio of the amount of agent included in the aerosol forming substance to the mass of the substrate is from 0.01 to 8.0.
The use of negative-modifying agents, such as levulinic acid and glucose penta-45 acetate in glucose, in the preferred smoking articles according to the invention reduces the sharpness of the aerosol produced by the smoking article by altering the pH of the aerosol, aromatic substances, etc., an aerosol produced by the smoking article, or both. Moreover, as noted above, this occurs without the formation of undesirable by-products or taste impairment. It has been found that the pH of aer rzol produced by smoking

product using a modifying agent in accordance with the invention, similar to the pH of the smoke produced when smoking conventional cigarettes. In addition, it was found that the resulting aerosol is more prone in the sense that it irritates the oral cavity, nose and throat of the user less. Thus, these products have an improved taste and provide the user with greater smoking pleasure.
In an advantageous embodiment, the modifying agent of the invention is used in aerosol formation means, in particular on a substrate material that serves as a carrier of the substance (or substances) forming the aerosol.
The mass fraction of the modifying agent in the substrate used in the aerosol forming media can vary widely depending on various variables, including the amount of nicotine or other flavors introduced into the aerosol stream, the type of flavors used, i.e. alkaline flavoring agents may require an additional amount of a modifying agent, the type of specific modifying agent used, and whether the modifying agent is used in one or more components of the smoking article.
The modifying agent according to the invention can be incorporated into the aerosol forming means in various ways. For example, when the aerosol forming agents contain a substrate material as a carrier forming an aerosol, the modifying agent can be mixed with the aerosol forming substance added as dust or powder to the substrate, or it can be dissolved or dispersed in H20 or in EtOH and then deposited on the substrate by spraying or dipping, etc.
The modifying agent may also be used in one or more other components of the smoking article. In this case, the amount used should be sufficient so that the pH of the resulting aerosol stream is the same as KaKv and regular cigarette smoke. However, the introduction of modifying agents should be avoided.
This is a combustible element to minimize the formation of unwanted by-products.
The aerosol generating agent is enclosed by the tobacco-containing mass layer 4 and includes a heat-conducting element that is made in the form of a metal capsule 5, the aerosol-forming material is enclosed in this capsule, and the tobacco-containing mass layer 4 encloses the said capsule 5 that contacts the fuel cell 1 when This last covered insulating element 6 fiberglass. At the mouth end of the capsule, two target channels 7 are provided in the center. Mouthpiece 2 contains a ring of acetate cellulose 8 and a segment of sheet nonwoven polypropylene fabric 9 through which the aerosol passes to the smoker. The fuel element 1 has longitudinal channels 10, preferably thirteen, and arranged as shown in FIG. 2. This combustible element is formed from an extruded mixture of carbon (from carbon paper), the binder is sodium carboxymethylcellulose, K2CO3, and water.
The smoking article is wrapped with several layers of 11-17 tissue paper.
When this product is ignited, the combustible element 1 burns, generating heat used to evaporate the tobacco flavoring material and any additional substance or substances forming an aerosol as part of the aerosol forming means. Since the combustible element is relatively short, the combustible cone of the burning flame is always in the immediate vicinity of the aerosol formation means, which contributes to
maximizing heat transfer to the aerosol formation means and, as a result, producing the aerosol.
Due to the small size and special characteristics of the combustion of the fuel element, it usually after several hours begins to burn over almost the entire free length. Thus, a portion of the fuel element 1 adjacent to the aerosol generating means quickly becomes hot, which significantly increases the heat transfer to the aerosol generating means, especially during the first and subsequent puffs. Since the predominant fuel cell
is so short, there is no long section of unburned fuel cell acting as a heat absorbing agent, which was usually in previously known thermal aerosol products. Since the aerosol-forming substance is physically separated from the fuel cell,

the aerosol is exposed to significantly lower temperatures than those developed by the fuel cell, which minimizes the likelihood of thermal decomposition. Similarly, the lower temperatures used to form the aerosol significantly reduce the amount of unwanted by-products associated with the modifying agents used to reduce the sharpness of the aerosol produced.
The substance or substances forming the aerosol used in the articles according to the invention 5 must be capable of forming an aerosol at temperatures developing in the means of forming the aerosol when heated by the action of the combustion of the fuel cell. Such substances are predominantly non-tobacco, non-aqueous aerosol forming substances and consist of carbon, hydrogen and oxygen, but they may include other materials. Such substances may be in solid, semi-solid or liquid state. The boiling point or sublimation of a substance and / or a mixture of substances can reach up to about 500 ° C. Substances with such characteristics include polyhydric alcohols, such as glycerin, triethylene glycol and propylene glycol, as well as aliphatic mono-, di- and polycarboxylic acids, such as methyl stearate, dodecanoate, dimethyltetradodecanoate and others.
The preferred aerosol forming substances are polyhydric alcohols or mixtures of polyhydric alcohols. More preferred aerosol forming agents are selected from glycerin, triethylene glycol and propylene glycol.
When the substrate material is used as a carrier, the aerosol-forming substance can be dispersed by any known method on the surface or inside the substrate in
a concentration sufficient to penetrate into the material or to form a coating on it. For example, an aerosol forming agent may be applied in full concentration or applied from a dilute solution by dipping, spraying, vapor deposition or similar methods. The solid components forming the aerosol can be mixed with the substrate material and evenly distributed elsewhere in the other until the formation of the final substrate.
Although the dosage of the substance forming the aerosol will vary depending on the type of carrier and the type of substance forming the aerosol, the amount of liquid substances forming the aerosol can usually vary from l / 20 to "140 mg, mainly from A / 40 up to l / 110 mg. The maximum possible amount of an aerosol forming substance deposited on the substrate, ku, must be supplied to the user in the form of WTPM. Preferably, the mass fraction of the aerosol forming substance deposited on the substrate and delivered to the user in the form of WTPM is more than 2%, predominantly over 15% and most predominantly over 20%.
Aerosol formation agents may also contain one or more flavoring volatile agents, such as menthol, vanillin, artificial coffee, tobacco extracts, nicotine, caffeine, liqueurs, and other agents that enhance the flavor of the aerosol. They may also contain any other desired volatile solid or liquid materials. These additional agents can be placed between the aerosol formation means and the mouthpiece, for example, on a separate Isha substrate in the chamber, either in the form of a covering of the channel leading to the mouthpiece, or in an additional portion of tobacco.
One of the particularly preferred aerosol forming agents comprises an alumina substrate containing sprayed and dried tobacco extract, levulinic acid or glucose pentaacetate, one or more flavoring agents, and an aerosol forming agent such as glycerin.
Portion of tobacco, which can also be part of the modifying agent
According to the invention, it may be located behind the fuel element. In these cases, the hot fumes are entrained through tobacco, extraction and sublimation of volatile components from the tobacco without burning it or significant pyrolysis. Thus, the user receives an aerosol containing the flavor and aroma of natural tobacco without the numerous combustion products contained in a conventional cigarette.
Products of the type described may be used or modified for use as a means of delivery to a drug user, for delivering pharmacologically volatile or physiologically active materials, such as ephedrine, metaproterenol, terbutaline or the like.
The use of this product containing an aerosol-forming substance comprising the specified agent will reduce the sharpness of the aerosols and eliminate the formation of undesirable by-products and the deterioration of taste.
