When reference symbols refer to components of each drawing, it should be noted that like components, even if they are shown in different drawings, have the same reference symbols whenever possible. In addition, if it is found in the description of a specific example that the description of a corresponding known configuration or function interferes with the understanding of the specific example, its detailed description will be omitted.

In addition, when describing the components of the present invention, terms such as "first", "second", "A", "B", "(a)", "(b)", etc. may be used. These terms are intended only to distinguish components from other components, but not to limit the nature, sequence or order of components. When a component is disclosed as being "connected", "connected", or "coupled" to another component, it should be understood that while a component may be directly connected to or associated with another component, there may nonetheless be "connected" between two components. "connected" or "connected" the respective components.

Components used in any of the embodiments and components having a common function will be described using the same names in other embodiments. Unless otherwise indicated, descriptions in any of the embodiments are applicable to other embodiments, and detailed descriptions in overlapping cases will be omitted.

In this specification, "smoking article" may mean an aerosol-generating article such as a cigarette, cigar, or the like. The smoking article may contain an aerosol generating material or substrate. In addition, solid materials based on tobacco raw materials, such as homogenized tobacco web, cut tobacco leaf, homogenized tobacco, and the like, may be included in the smoking article. The smokable material may contain a volatile substance. A smoking article may comprise several segments, each with its own functionality, referred to as "parts". In this specification, the smoking article may be a heated cigarette used together with an aerosol generating device (not shown in the figure) such as an electronic cigarette device, as well as a combustible cigarette, but given that the present invention has an improvement effect, especially in terms of side smoke flow, it is preferable to use a combustible cigarette.

As used herein, "homogenized flavored tobacco leaf" refers to a flavor-containing homogenized tobacco web capable of releasing flavor at room temperature or under heating conditions, the type of flavor being substantially unrestricted as long as it is commonly used in the art.

In this description, the terms "upper" and "lower" are used to refer to the relative positions of the segments that make up the smoking article, depending on the direction in which the user inhales air with the smoking article. The smoking article comprises an upper end (ie the part into which air enters) and a lower end (ie the part from which air exits). While using the smoking article, the user may hold the lower end of the smoking article. The lower end is located below the upper end, and the "end" may also be referred to as the "distal end".

The present invention relates to a smoking article, and according to one embodiment of the present invention, the smoking article comprises a smoking material part and a filter part. In particular, FIG. 1 is a diagram illustrating a schematic configuration of a smoking article according to one embodiment of the present invention. In the smoking article 100, the smoking material portion 10 is located above the filter portion 20 in the direction of flow.

The smoking material portion 10 may be filled with smoking material such as raw tobacco leaf, homogenized tobacco leaves, or a mixture of tobacco leaf and homogenized tobacco leaves. The processed smokable material may be filled into the smokable material portion 10 in the form of a web or cut tobacco leaf. The smokable material portion 10 may be in the form of an elongated rod whose length, circumference and diameter are not substantially limited, but can be set to local dimensions based on the amount of smokable material loaded, user preferences, etc. The smoking material portion 10 may contain at least one of the following aerosol generating materials: glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The smokable material 10 may contain other additives such as a flavoring agent, a wetting agent, and/or an acetate compound. The aerosol generating material and additive materials may be contained in the smokable material.

In one of the embodiments of the present invention, the portion 10 of the smokable material contains cut, homogenized tobacco leaves containing flavoring. Chopped homogenized tobacco leaves are obtained by cutting a homogenized tobacco web, which is a web made from tobacco particles obtained by crushing or grinding one or both leaf blades and stem of a tobacco leaf taken as raw materials. The homogenized tobacco web can be produced by a pulp homogenization process, an impression reconstitution process, a slurry reconstitution process, and the like according to a manufacturing method, and a homogenized tobacco web produced according to the corresponding manufacturing method is distinguished by internal structure, physical properties, and the like. Chopped homogenized tobacco leaves according to one embodiment of the present invention may be sliced pulp homogenized tobacco leaves made by cutting a pulp homogenized tobacco web made in a pulp homogenization process. The pulp-homogenized tobacco web or cut pulp-homogenized tobacco sheet is highly hygroscopic and the like, and thus can maintain excellent workability even when a certain or more flavoring agent or the like is added.

The cut homogenized tobacco leaves contain a flavorant, but in the case of homogenized tobacco leaf pulp, the material of the homogenized tobacco leaves is made into cut tobacco paper, which may be impregnated with a flavoring agent or coated with a flavoring agent, after which it is compressed to introduce the flavoring agent into the homogenized tobacco leaves. The flavor may contain menthol, peppermint, spearmint oil, various fruit flavor components and the like, and is not particularly limited as long as the material is commonly used in the art.

In one of the embodiments of the present invention, the flavoring agent is contained in the cut homogenized tobacco leaves in an amount of from 4 to 20 wt.%, in particular, from 6 to 16 wt.%, more precisely from 8 to 12 wt.% of the mass of cut homogenized tobacco leaves. If the flavor content exceeds the above range, the flavor perception may be excessive, which reduces user satisfaction, and processability may also be reduced due to the flavor remaining after the flavor penetrates into the cut homogenized tobacco leaves. If the flavor content is less than the above range, the sidestream flue quality improvement effect due to the addition of flavor may be small.

The cut homogenized tobacco leaves may contain at least one of the following aerosol generating materials: glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol, as well as other smoking materials contained in the part of the smoking material, and may additionally contain other additive materials such as a flavoring agent, a wetting agent and/or an acetate compound. If the total content of auxiliary materials is increased by the content of fragrance, aerosol-generating material and other auxiliary materials, workability can be improved by additionally adding a binder material. As a binder, natural gum can be used, given that a person can also inhale the binder, as well as additional materials. In one embodiment of the present invention, the binder is guar gum and/or gum arabic.

In one of the embodiments of the present invention, the cut homogenized tobacco leaves containing flavoring are present in the part of the smoking material in an amount of from 5 to 25 wt.%, in particular, from 6 to 20 wt.%, more precisely, from 8 to 16 wt.% , based on the mass of a part of the smoking material. If the content of chopped homogenized tobacco leaves containing flavor exceeds the above range, the flavor sensation will be excessive, which will reduce user satisfaction, and the content of tobacco leaf, which is a raw material with high functionality, in particular nicotine migration and the like, can be reduced in parts of the smoking material, which will reduce the user's satisfaction with smoking. If the content of cut homogenized tobacco leaves containing flavor is less than the above range, the effect of improving sidestream smoke by adding cut homogenized tobacco leaves containing flavor may be negligible.

The length of the cut homogenized tobacco leaves containing the flavorant may be less than the diameter of the rod-shaped portion 10 of the smoking material, which will allow the portion 10 of the smoking material to be properly filled. In this case, the length of cut homogenized tobacco leaves means the length of the longest segment from any point on the surface of cut homogenized tobacco leaves to another point on the surface. In one embodiment of the present invention, the cut homogenized tobacco leaves comprise 20 wt.% or more, in particular 25 wt.% or more, more precisely 30 wt.% or more of cut homogenized tobacco leaves, the length of which exceeds the diameter of the part of the smokable material. In order for sliced homogenized tobacco leaves whose length exceeds the diameter of the smoking material part can be filled into the smoking material part 10, the length in at least one direction must be less than the diameter of the smoking material part, and the part of the cut homogenized tobacco leaves whose length exceeds the diameter part of the smoking material is oriented horizontally in the longitudinal direction of the part of the smoking material. When the smoking article is a combustible cigarette, the cut homogenized tobacco leaves constituting the smoking material portion 10 are burned in the longitudinal direction of the smoking material portion. Meanwhile, when the cut homogenized tobacco leaves containing the flavoring agent are oriented so as to be elongated in the longitudinal direction, the durability of the sidestream odor improving effect can be increased.

In one embodiment of the present invention, sliced homogenized tobacco leaves that are longer than the diameter of the smoking material portion occupy 70% or more, in particular 75% or more, more specifically 80% or more, of the longitudinal direction of the smoking material portion. In this case, "occupying 70% or more, in particular 75% or more, more precisely 80% or more in the longitudinal direction" means that the proportion of the corresponding material is 70% or more, 75% or more, or 80% or more of the total length of the part of the smoking material taken as 100%. "Relevant material" means that the material is found in a cross section perpendicular to the longitudinal direction. The aforementioned sliced homogenized tobacco leaves having a long length can cover the longitudinal direction of a part of the smoking material with one or more sliced homogenized tobacco leaves and should be arranged so as not to overlap in the longitudinal direction, that is, even with a small amount, the maximum volume area can be covered. . If the cut, homogenized flavor-containing tobacco leaves cover 70% or more of the smoking material in the longitudinal direction, the user may continuously experience an improvement in the sidestream smoke flavor until the end of smoking.

The filter part 20 is located below the smoking material part 10 and serves as a filter through which the aerosol material generated in the smoking material part 10 passes just before it is inhaled by the user. The filter part 20 may be formed from various materials, and for example, the filter part 20 may be a cellulose acetate filter. The filter part 20 may be either a cellulose acetate filter in which the flavor material is not processed, or a transfer jet system (TJNS) filter in which the flavor material is processed.

In one of the embodiments of the present invention, the filter part 20 may be a tubular structure with a cavity inside. The filter part 20 can be made by inserting into its interior (eg a cavity) a structure, in particular a film or tube, of the same or a different material. Part 20 of the filter in accordance with one of the embodiments of the present invention is shown in FIG. 1 as a single filter monofilter, but the invention is not limited to this embodiment. For example, it is natural that the filter portion 20 can be configured as a double or triple filter with two acetate filters to improve filtration efficiency. In addition, although not shown in the figure, a crushable capsule (not shown in the figure) in which the inner liquid containing the flavor is wrapped with a film can also be included in the filter portion 20.

The outer side of the smoking material part 10 and the filter part 20 may be wrapped with a wrapper 30a or 30b.

The smoking material part 10 may be wrapped with the smoking material part wrapper 30a. Part of the cigarette smoke generated during the combustion of the common smoking material part 10 is released into the atmosphere through the smoking material part wrapper 30a before passing through the cigarette filter, and the sidestream smoke causes discomfort to those around the smoker. Various attempts have been made to reduce such sidestream smoke, for example, fillers such as magnesium oxide, titanium oxide, cerium oxide, alumina, calcium carbonate and zirconium carbonate have been added to conventional cigarette paper. However, if the side flue flow is reduced by simply using these fillers, the taste of the smoke deteriorates, or burnout, reduction in ash fineness, and the like occurs, that is, the problems that arise are difficult to solve by a proper combination of the materials included in the fillers. Magnesium oxide (MgO and/or Mg(OH) ₂ ) and calcium carbonate (CaCO ₃ ) are applied to wrapper 30a of a piece of smoking material in accordance with one embodiment of the present invention to prevent smoking off-flavour, reduce ash fineness and burnout while reducing lateral smoke flow.

The filter part 20 may be wrapped with the filter part wrap 30b. The filter part wrap 30b may be made of grease-proof wrapping paper, and aluminum foil may be additionally applied to the inner surface of the filter part wrap 30b.

The smoking material part 10 wrapped with the smoking material part wrap 30a and the filter part 20 wrapped with the filter part wrap 30b may be combined and wrapped with wrapping paper 40. The wrapping paper 40 may be wrapped around at least a part (for example, the part below in the direction of flow) of the wrapper 30a of the smoking material part and the outer periphery of the wrapper 30b of the filter part, as shown in FIG. In other words, at least the smokable material portion 10 and the filter portion 20 may be wrapped in wrapping paper 40 and physically combined. In one of the embodiments of the present invention, the wrapping paper 40 may be, in particular, non-porous wrapping paper that does not have grease-proof properties. In addition, the wrapping paper 40 can also prevent the filter portion 20 from being ignited, in particular by including a non-combustible material.
