The present invention relates to a smoking article, and according to an embodiment of the invention, the smoking article includes a smoking material part and a filter part. For reference, Figure 1 is a schematic configuration diagram of a smoking article according to one embodiment of the present invention. In the smoking article 100, the smoking material portion 10 is located upstream of the filter portion 20.

The smoking material portion 10 may be filled with, for example, raw leaf tobacco, reconstituted tobacco leaves, or a mixture of tobacco leaves and reconstituted tobacco leaves. The processed smoking material may be filled in the smoking material portion 10 in the form of sheets or cut tobacco leaves. The smoking material part 10 may have an elongated rod shape, and its length, circumference, and diameter are not particularly limited, but may be adjusted to those commonly used in the field by considering the filling amount of the smoking material, the user's preference, etc. size of. The smoking material portion 10 may include at least one aerosol-generating material selected from the group consisting of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Smoking material portion 10 may contain other additive materials such as flavoring agents, wetting agents, and/or acetate compounds. Smoke generating materials and additive materials may be included in the smoking material.

According to one embodiment of the present invention, the smoking material portion 10 includes cut and reconstituted tobacco leaves containing flavoring agents. Cut reconstituted tobacco leaves are made by cutting reconstituted tobacco sheets into sheets. The reconstituted tobacco sheets are sheets made from particulate tobacco, where the particulate tobacco is made by cutting leaf lamina as the raw material. It is made by grinding or pulverizing one or both of tobacco leaf stem and tobacco leaf stem. The reconstituted tobacco sheet can be manufactured through a paper reconstituted process, a cast reconstituted process, a slurry reconstituted process, and similar processes according to respective manufacturing methods, and according to each manufacturing method The reconstituted tobacco sheets produced by the method have differences in internal structure, physical properties, or similar characteristics. The cut reconstituted tobacco leaves according to one embodiment of the present invention may be paper cut reconstituted tobacco leaves produced by cutting paper cut reconstituted tobacco sheets produced using a paper reconstituted process. Paper-shaped restructured tobacco sheets or paper-shaped cut restructured tobacco leaves have excellent water absorption and other similar properties, and therefore can maintain excellent processability even when more than a certain amount of flavoring and other materials are added.

Cut tobacco leaves contain flavoring agents, but in the case of paper-like reconstituted tobacco leaves, cut tobacco paper is made from the material of reconstituted tobacco leaves, which may be impregnated in flavoring agents or applied with flavoring agents, and Pressurization is continued to allow the flavoring agent to penetrate into the reconstituted tobacco leaves. The flavoring agent may include menthol, peppermint, spearmint oil, various fruit flavor ingredients, and the like, and the type of flavoring agent is not particularly limited, and it may be any type commonly used in related fields.

According to one embodiment of the present invention, the flavoring agent is included in the cut restructured tobacco leaves in an amount of 4 to 20 weight percent based on the weight of the cut restructured tobacco leaves, specifically 6 weight percent. The ratio is to 16 weight percent, and more specifically 8 to 12 weight percent. If the content of the flavoring agent exceeds the above range, the user may experience excessive aroma and reduce user satisfaction, and the processability may also be impaired due to the flavoring agent remaining after the flavoring agent penetrates into the cut reconstituted tobacco leaves. reduce. When the content of the flavoring agent is less than the above range, the effect of improving the side stream smoke by adding the flavoring agent may not be significant.

The cut reconstituted tobacco leaves may include at least one aerosol-generating material selected from the group consisting of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, together with the aerosol-generating material contained in the smoking material portion 10 As with other smoking materials, they may further contain other additive materials, such as flavoring agents, wetting agents, and/or acetate compounds. If the total content of additive materials is increased by including flavoring agents, aerosol-generating materials, and other additive materials, processability can be improved through the addition of additional binding materials. Taking into account the fact that adhesive materials may actually be inhaled into the human body as well as additive materials, natural glue may be used as the adhesive material. According to an embodiment of the present invention, the adhesive material is guar gum, gum arabic, or a combination thereof.

According to one embodiment of the present invention, the cut restructured tobacco leaves containing flavoring agents are included in the smoking material portion 10 in an amount of 5 to 25 weight percent based on the weight of the smoking material portion 10 , specifically 6 to 20 weight percent. , and more specifically 8 to 16 weight percent. If the content of the cut recombinant tobacco leaves containing the flavoring agent exceeds the above range, the user may feel excessive flavor and the user's satisfaction is reduced, and the smoking material part 10 may have high levels of nicotine migration, etc. The content of functional raw materials in tobacco leaves may be reduced, which may reduce users' smoking satisfaction. If the content of the flavoring-containing cut and reconstituted tobacco leaves is less than the above range, the effect of improving sidestream smoke by adding the flavoring-containing cut and reconstituted tobacco leaves may not be significant.

The length of the cut and restructured tobacco leaves containing the flavoring agent may be shorter than the diameter of the rod-shaped smoking material part 10 so as to be properly filled in the smoking material part 10 . Here, the length of the cut restructured tobacco leaves means the longest length among the lengths from any point on the surface of the cut restructured tobacco leaves to another point on the surface. According to one embodiment of the present invention, the cut reconstituted tobacco leaves comprise 20% by weight or more of cut reconstituted tobacco leaves that are longer than the diameter of the smoking material part 10 , specifically 25% by weight or more, and more specifically 30% by weight or More. In order to fill the smoking material part 10 with cut and restructured tobacco leaves longer than the diameter of the smoking material part 10 , its length in at least one direction needs to be shorter than the diameter of the smoking material part 10 , and in the cut and restructured tobacco leaves, it is longer than the smoking material part 10 . A portion of the diameter of the portion 10 is oriented horizontally in the longitudinal direction of the smoking material portion 10 . When the smoking article is a burning cigarette, the cut and restructured tobacco leaves contained in the smoking material part 10 are burned along the longitudinal direction of the smoking material part 10 . At this time, by orienting and elongating the cut restructured tobacco leaves containing the flavoring agent in the length direction, the durability of the odor improving effect of the side stream smoke can be improved.

According to one embodiment of the present invention, the cut restructured tobacco leaves longer than the diameter of the smoking material part 10 cover 70% or more, specifically 75% or more, and more specifically 80% or more of the longitudinal direction of the smoking material part 10 More often. Here, "covering 70% or more, 75% or more, or 80% or more in the longitudinal direction" means When the total length of the smoking material portion 10 is 100%, 70% or more, 75% or more, or 80% or more of the particular material is present. "There is a specific material" means that the specific material is found in a cross-section perpendicular to the longitudinal direction. The above-mentioned cut and restructured tobacco leaves with a longer length can cover the longitudinal direction of the smoking material part 10 through one or more pieces of cut and restructured tobacco leaves, and need to be arranged so as not to overlap in the longitudinal direction, so that even a small number can cover the widest possible area. Fan around. If the cut restructured tobacco leaves containing flavorings cover 70% or more of the smoking material portion 10 in the longitudinal direction, the user can continue to feel the improvement effect of the sidestream smoke odor until the smoking is completed.

The filter portion 20 is provided downstream of the smoking material portion 10 and serves as a filter through which the aerosol material generated in the smoking material portion 10 passes immediately before being inhaled by the user. The filter part 20 may be formed of various materials. For example, the filter part 20 may be a cellulose acetate filter. The filter portion 20 may be a cellulose acetate filter in which no flavoring material is treated, or a Transfer Jet Nozzle System (TJNS) filter in which flavoring material is treated.

According to one embodiment of the present invention, the filter portion 20 may be a tubular structure containing a hollow therein. The filter portion 20 may be manufactured by inserting a structure (eg, hollow) such as a membrane or a tube made of the same or different materials therein. The filter part 20 according to one embodiment of the present invention is shown as a mono filter formed of a single filter in Figure 1, but is not limited thereto. For example, in order to improve the filtration efficiency, the filter part 20 may also be configured as a dual filter or a triple filter having two cellulose acetate filters. In addition, although not shown, the filter portion 20 may also include a crushable capsule (not shown) having a structure in which an internal liquid containing a flavoring agent is wrapped by a film.

The outer sides of the smoking material part 10 and the filter part 20 may be wrapped by wrapping paper (smoking material part wrapping paper 30a or filter part wrapping paper 30b).

The smoking material portion 10 may be wrapped by a smoking material portion wrapper 30a. Some cigarette smoke generated during the burning process of the general smoking material part 10 is released into the atmosphere through the smoking material part wrapper 30a before passing through the cigarette filter, and this side flow smoke will cause discomfort to people who inhale second-hand smoke. Various attempts have been made to reduce this sidestream smoke, such as adding fillers such as magnesium oxide, titanium oxide, cerium oxide, aluminum oxide, calcium carbonate, and zirconium carbonate to conventional cigarette papers. However, if only these fillers are used to reduce sidestream smoke, the smoke flavor will be reduced, or burnt, ash fineness will be reduced, etc. Therefore, it will be difficult to penetrate the materials contained in the filler. Appropriate combinations to solve these problems. The smoking material part wrapper 30a according to one embodiment of the present invention uses magnesium oxide (MgO and/or Mg(OH) ₂ ) and calcium carbonate (CaCO ₃ ) to avoid smoke flavor, reduction in ash fineness, and burning, And also reduces sidestream smoke.

The filter part 20 may be wrapped by the filter part wrapper 30b. The filter part wrapper 30b may be made of oil-resistant wrapper, and may further include aluminum foil on the inner surface of the filter part wrapper 30b.

The smoking material part 10 wrapped by the smoking material part wrapper 30a and the filter part 20 wrapped by the filter part wrapper 30b may be combined and wrapped using the filter joint paper 40. The filter bonding paper 40 may surround at least a portion (downstream partial area) of the smoking material portion wrapper 30a and the periphery of the filter portion wrapper 30b, as shown in FIG. 1 . In other words, at least a portion of the smoking material portion 10 and the filter portion 20 may be further wrapped by and physically coupled thereto by filter bonding paper 40 . According to an embodiment of the present invention, the filter bonding paper 40 may be made of non-porous packaging paper that is not resistant to oil, but is not limited thereto. In addition, the filter bonding paper 40 may further contain non-combustible materials to prevent the filter component 20 from burning, but is not limited thereto.
