Article for providing aerosol to oral cavity or lung

Abstract

An article for providing an aerosol to an oral cavity or a lung. The article has a rod-shaped structure and comprises an aerosol matrix section. The aerosol matrix section comprises an aerosol matrix and paper wrapping the aerosol matrix. The aerosol matrix comprises two or more components, each component comprises a plant material or a matrix material prepared from a substance comprising the plant material, and the hardness of at least one of the components is greater than the average hardness of the other component(s). Under the condition of the same filling density, the overall hardness of the aerosol matrix section is significantly improved. Moreover, when the component material with high hardness is a material that has improved hardness after treatment, only the wrapping pressure in the rolling process can cause the material that has improved hardness after treatment to show a certain degree of adhesion, so that all the components in the aerosol matrix section can be partially bonded, thereby improving the overall hardness without significantly reducing gaps in the aerosol matrix section, thus ensuring the thermal transfer effect.

Description

An article used to deliver an aerosol to the mouth or lungs Technical Field

[0001] The present invention belongs to the field of agricultural product application and medical technology, and in particular relates to an article for providing aerosol to the oral cavity or lungs. Background Art

[0002] In agricultural products, such as tobacco, when consumers smoke cigarettes made from tobacco leaves, the smoke produced by the cigarettes enters the lungs through the mouth. It is simple to smoke and can be smoked at any time in places where smoking is allowed. Studies have found that the smoke produced by certain plants has a very good therapeutic effect on some oral or lung diseases after entering the mouth or lungs.

[0003] For some diseases involving the mouth or lungs, direct drug delivery via spray is an effective treatment. Spraying medication directly into the mouth or lungs in the form of an aerosol directly onto the affected area can enhance therapeutic efficacy. However, existing spray devices are bulky, and some require a dedicated power source, forcing patients to visit a hospital for spray therapy.

[0004] Whether burning conventional tobacco or other plants, the smoke produced can affect the environment in public places. During the combustion process, temperatures reach around 800°C, causing some components to decompose and produce harmful substances. Consequently, heated cigarettes have been developed. By heating the smoking device at around 300°C, the smoking components are atomized into an aerosol for consumption by consumers. Heating methods used in smoking devices include resistance heating, infrared heating, and electromagnetic heating. During use, the smoking section of the cigarette must be inserted into the smoking device, which requires a certain degree of strength. To achieve this, sufficient hardness or strength is often used to support the cigarette, or a long filament of the smoking matrix is ​​used to enhance the overall strength of the smoking matrix. However, using strong cigarette paper results in poor results with infrared and resistance heating methods, and using a long filament of the smoking matrix makes mass production difficult.

[0005] Summary of the Invention

[0006] The object of the present invention is to provide an article for providing aerosol to the oral cavity or lungs, so as to solve the problems existing in the above-mentioned background technology.

[0007] To achieve the above objectives, this application is implemented through the following technical solutions:

[0008] An article for providing an aerosol to the oral cavity or lungs, the article being a rod-shaped structure and comprising an aerosol matrix segment, wherein the aerosol matrix segment comprises an aerosol matrix and paper wrapping the aerosol matrix;

[0009] The aerosol matrix includes two or more components, each of which includes plant materials or a base material prepared from substances including plant materials, and the hardness of at least one component is greater than the average hardness of the other components.

[0010] Furthermore, the base material of each component is the same or different.

[0011] Furthermore, the material of the component with high hardness is a material that has its own hardness or a material whose hardness is increased after being processed.

[0012] Furthermore, the difference between the hardness value of the component with greater hardness and the average hardness value of other components is ≥5.

[0013] Furthermore, the material with increased hardness after treatment is a gel with increased hardness sprayed on a base material.

[0014] Furthermore, the surface viscosity of the component with high hardness after spraying the gel does not cause it to adhere to each other or to other components unless subjected to external pressure.

[0015] Furthermore, the content of the component with high hardness accounts for more than 30% of the aerosol matrix by weight.

[0016] The beneficial effects of the present invention are:

[0017] This technical solution uses a material with high hardness as at least one component in the composition of the aerosol matrix. When it is wrapped with paper to form an aerosol matrix segment, the overall hardness of the aerosol matrix segment is significantly improved under the same filling density. Moreover, when the component material with high hardness is a material that has been processed to increase the hardness, no material adhesion will occur during the normal production process. Only when the wrapping pressure is applied during the rolling process will a certain degree of adhesion appear, partially bonding the components in the aerosol matrix segment, thereby improving the overall hardness. The voids inside the aerosol matrix segment will not be significantly reduced, thereby ensuring the heat transfer effect. DETAILED DESCRIPTION

[0018] The technical solution of the present invention is described in detail below. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and cannot be interpreted as limiting the technical solution of the present invention.

[0019] The present application provides an article for providing aerosol to the oral cavity or lungs. The article of the present application is a rod-shaped structure. Specifically, reference can be made to the shape of existing cigarettes, including conventional cigarettes and heat-not-burn cigarettes, that is, the entire structure is rod-shaped, which is specifically determined by the outer wrapping paper. The type of paper can be one or more, for example, one type of paper wraps the aerosol matrix to form an aerosol matrix segment, one type of paper wraps the mouth segment, and one type of paper connects the aerosol matrix segment and the mouth segment to form a rod-shaped shape.

[0020] In the present technical solution, one or more functional segments may be provided between the aerosol matrix segment and the mouth segment as required, such as structures for supporting, cooling, assisting in adding certain specific flavors, filtering and removing certain components or types of components in the aerosol, and the specific structure may be determined according to actual needs.

[0021] The aerosol matrix wrapped in paper means that after heating or ignition, part of the substance in the aerosol matrix can form an aerosol for the user to enter the mouth or lungs by inhalation. In the present application, it is preferred to use heating to form aerosol release of part of the substance in the aerosol matrix.

[0022] In the present application, the aerosol matrix is ​​composed of two or more components mixed in a set ratio. The specific number of components can be determined according to actual production needs. However, regardless of the number of components, the matrix material of each component is a natural plant or a substance prepared from natural plants. The natural plants here are plants grown or collected through agricultural cultivation, including the roots, stems, leaves, flowers, etc. of plants, such as tobacco leaves, tea leaves of tea trees, etc.; substances prepared from natural plants, such as reconstituted tobacco leaves prepared by adding other components using tobacco powder, particles, tobacco stems, etc. In the present application, the process of reconstituted tobacco leaves is existing conventional technology, such as papermaking, roller pressing, etc.

[0023] In order to improve or meet the user's sensory needs, corresponding additives may be added to the base material of each component according to design or needs. The additives include flavors, nicotine, Chinese herbal medicine extracts, smoke agents, etc. Here, the ingredients of flavors, Chinese herbal medicine extracts and smoke agents are not listed one by one. All usable ingredients can be used, and the amount used is also added according to the design.

[0024] Here, we take tobacco shreds processed from tobacco leaves as an example. After the tobacco shreds are cut into shreds, they are flavored according to current conventional production, that is, flavors and fragrances designed according to the formula, Chinese medicinal raw material extracts, such as chrysanthemum leaf extract, ginseng extract, etc., are added. A certain amount of smoke-generating agent can also be added as needed. The type of smoke-generating agent in this application is not limited, such as glycerin, propylene glycol, etc., and the specific amount is not limited. In this way, the preparation of a certain component in the aerosol matrix is ​​completed.

[0025] In the present application, the matrix materials of the various components of the aerosol matrix may be the same or different, depending on actual needs. The same matrix material here means that in the various components within the aerosol matrix segment, the matrix materials of each component are all made of the same material. For example, the matrix materials of the various components of the aerosol matrix are all tobacco prepared from cut tobacco leaves, and more specifically, they can be tobacco prepared from cut tobacco leaves of the same variety. In conventional production, different parts of the same variety of tobacco leaves are considered to be different tobacco leaves after being cut. However, in the present application, all tobacco leaves prepared from cut tobacco leaves of the same variety or grade, except for stems, are considered to be made of the same matrix material.

[0026] The aerosol matrix of the present application includes two or more components, and the hardness of at least one component is greater than that of the other components. The material of the component with high hardness here is the material with its own hardness or the material with increased hardness after treatment. In this technical solution, the components that constitute the aerosol matrix usually need to be processed, such as adding fragrance, adding additives, etc. The hardness of the material itself usually refers to the hardness of the base material itself, or the base material is treated to increase the hardness of the base material. Moreover, the hardness value of the component with high hardness (detected according to the currently used detection method) and the average hardness value of other components have a difference greater than 5.

[0027] In the technical solution of the present application, if the hardness of the material itself is large, here it refers to the hardness of the base material itself, which is not described in detail here. The focus is on the material with increased hardness after treatment, that is, spraying a gel with increased hardness on the base material. Taking the base materials of the various components of the aerosol matrix as an example, all of them are tobacco leaves prepared from tobacco leaves. By spraying the gel with increased hardness in the late stage of the tobacco processing to the flavoring and adding process, in the present application, the spraying of the base material does not require one surface or both surfaces of the base material. In the specific production process, there is a problem that some surfaces are not sprayed with the gel for increasing hardness during the spraying process. As long as the hardness is increased to a suitable hardness, there are many types of gels that can increase hardness in the existing technology, but food-grade gels need to be selected, such as chitosan-alginate, gel with corresponding ingredients added to agar, chitosan-polyvinyl alcohol hydrogel, sodium alginate-polyvinyl alcohol hydrogel, gelatin / polysaccharide colloid compound gel, etc., which are not described in detail here. Moreover, under normal circumstances, the surface viscosity of the hard component after spraying the gel on the base material is not significantly different from the surface viscosity of the component not sprayed with the gel. This is to avoid the situation of sticking together during the production process, especially before rolling, which affects normal production. Of course, non-stickiness can also be achieved by increasing the flipping frequency before rolling, and because the base material's anti-shattering performance is increased after spraying the gel.

[0028] Among all the components of the aerosol matrix, the content of the component with high hardness accounts for more than 30% of the aerosol matrix by weight percentage, but it is not recommended to exceed 75%. The technical solution adopts the component with high hardness to improve the hardness of the aerosol matrix segment after rolling on the one hand, so as to facilitate insertion into the receiving cavity of the smoking device. On the other hand, after spraying the gel, during the heating and smoking process, due to the barrier of the gel, in the early stage of smoking, the part of the component with high hardness that can form an aerosol cannot quickly form an aerosol and release. In the middle and late stages of smoking, the substance that can form an aerosol in the component with high hardness enters the smoke in large quantities, supplementing the reduction in the production of aerosol substances of the remaining components, resulting in the deficiency of corresponding substances in the smoke, thereby ensuring the stability of the aerosol content throughout the entire smoking process.

[0029] The above description is merely an embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application discloses the preferred embodiments as above, it is not intended to limit the present application. Any technical personnel familiar with the present profession, without departing from the scope of the technical solution of the present application, using the technical content disclosed above to make slight changes or modifications are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
