It should be understood that may be "connected", "coupled" or "connected".

Elements included in one embodiment and elements having common functions will be described using the same names in other embodiments. Unless described to the contrary, the description described in any one embodiment can also be applied to other embodiments, and specific descriptions will be omitted to the extent of overlap.

In this specification, the term "smoking article" may refer to an object capable of generating aerosol, such as cigarettes (cigarettes) and cigars. The smoking article may include an aerosol-generating material or an aerosol-forming substrate. In addition, the smoking article may include a solid material based on tobacco raw materials such as leaf tobacco, cut filler, and reconstituted tobacco. Smoking substances may contain volatile compounds. The smoking article may include several segments, each having a functional function, such segments as "... It is marked as “Part”. In the present specification, the smoking article may be not only a combustion type cigarette, but also a heating type cigarette used with an aerosol generating device (not shown) such as an electronic cigarette device, but considering that the present invention has an improved effect, particularly in sidestream smoke If so, combustion type cigarettes can be preferably applied.

In the present specification, the term “aroma leaf leaf” refers to a leaf leaf that can emit a fragrance at room temperature or under heating conditions, including a spice, and the type of the spice is not particularly limited as long as it is generally used in the art.

In this specification, the terms "upstream" and "downstream" are terms used to denote the relative positions of the segments constituting the smoking article with respect to the direction in which the user draws air using the smoking article. The smoking article includes an upstream end (ie, a portion through which air enters) and an opposite downstream end (ie, a portion through which air exits). When using the smoking article, the user may bite the downstream end of the smoking article. The downstream end is located downstream of the upstream end, while the term “end” may also be described as “end”.

The present invention relates to a smoking article, and according to one embodiment of the present invention, the smoking article includes a smoking substance portion and a filter portion. For reference purposes, FIG. 1 provides a diagram showing the schematic configuration of a smoking article according to one embodiment of the present invention. In the smoking article 100, the smoking substance portion 10 is located upstream compared to the filter portion 20.

The smoking substance unit 10 may be filled with smoking substances such as raw leaf tobacco, leaf tobacco, or a mixture of leaf tobacco and leaf tobacco. The processed smoking material may be filled in the smoking material unit 10 in the form of a sheet or cut filler. The smoking material unit 10 may have a long elongated rod shape, and its length, circumference and diameter are not particularly limited, but a size generally used in the related art considering the filling amount of smoking material, user's preference, etc. can be adjusted with The smoking material part 10 may include at least one aerosol generating material selected from glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol. The smoking substance portion 10 may contain other additives such as flavoring agents, humectants and/or acetate compounds. The aerosol-generating substances and additives may be contained in smoking substances.

According to one embodiment of the present invention, the smoking material portion 10 includes a planar leaf cut filler containing a flavoring agent. The planar leaf cut filler is prepared by cutting a planar leaf sheet, and the planar leaf sheet is a sheet made of particulate tobacco obtained by grinding or pulverizing one or both of leaf lamina and tobacco leaf stem as a raw material. . The platelet sheet may be manufactured by a papermaking method, a rolling method, a slurry method, etc. according to a manufacturing method, and the platelet sheet manufactured according to each manufacturing method has a difference in internal structure or physical properties. The sheet cut leaf cut filler according to one embodiment of the present invention may be a paper cut sheet cut filler prepared by cutting a paper-made sheet cut sheet manufactured according to a paper-making method. The paper-type planar leaf sheet or paper-type planar leaf cut filler has excellent hygroscopicity and can maintain excellent fairness even when substances such as spices are introduced at a certain level or more.

The planar leaf cut filler contains a fragrance, and in the case of paper-type planar leaf, paper is prepared from the material of the planar leaf, impregnated with a fragrance or applied with a fragrance, and then pressurized to infiltrate the fragrance into the planar leaf. The fragrance may include menthol, peppermint, spearmint oil, various fruit flavoring ingredients, and the like, and is not particularly limited as long as it is a material commonly used in the art.

According to one embodiment of the present invention, the spice is 4% to 20% by weight, specifically 6% to 16% by weight, more specifically 8% to 12% by weight based on the weight of the planar leaf cut filler. It is contained in the upper leaf cut sheath. When the content of the spice exceeds the above range, the user's satisfaction may be reduced because the fragrance is excessively felt, and fairness may be deteriorated due to the remaining spice after the spice penetrates into the planar cut grass. When the amount of the spice is less than the above range, the effect of improving sidestream smoke due to the addition of the spice may be insignificant.

Like the smoking materials included in other smoking material parts, the sheet leaf cut filler includes at least one aerosol generating material selected from glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol and may additionally contain other additives such as flavoring agents, wetting agents and/or acetate compounds. When the content of the total additives increases due to the inclusion of fragrances, aerosol generating materials, and other additives, it is possible to improve processability by additionally adding binding materials. Natural gum can be used as a binding material considering that the binding material can actually be inhaled into the human body like the additive material. According to one embodiment of the present invention, the binding material is guar gum, gum arabic or a combination thereof.

According to one embodiment of the present invention, the planar leaf cut filler containing the fragrance is 5% to 25% by weight, specifically 6% to 20% by weight, more specifically 8% to 8% by weight based on the weight of the smoking material part. 16% by weight is included in the smoking substances part. If the content of the planar leaf cut filler containing the flavor exceeds the above range, the user's satisfaction may be reduced due to excessive fragrance, and the content of the raw material leaf tobacco having high functionality such as nicotine transfer in the smoking material part is reduced, thereby reducing the user's satisfaction. Smoking gratification may be reduced. When the content of the planar cut filler containing the spice is less than the above range, the sidestream smoke improvement effect due to the addition of the planar cut filler containing the spice may be insignificant.

The planar leaf cut filler containing the spice may have a length shorter than the diameter of the rod-shaped smoking material unit 10 so that it can be properly filled in the smoking material unit 10. Here, the length of the plate cut sheath means the longest length of the lengths from any one point on the surface of the plate cut cut sheath to another point on the surface. According to one embodiment of the present invention, the sheet cut filler includes 20% by weight or more, specifically 25% by weight or more, and more specifically 30% by weight or more of a platelet cut filler having a length longer than the diameter of the smoking material part. In order for the sheet leaf cut filler having a length longer than the diameter of the smoking substance portion to be filled in the smoking substance portion 10, the length in at least one direction must be shorter than the diameter of the smoking substance portion, and the length of the sheet leaf cut filler is greater than the diameter of the smoking substance portion. The long portion is oriented horizontally to the length direction of the smoking material portion. When the smoking article is a combustible cigarette, the leaf cut filler included in the smoking substance portion 10 is burned along the longitudinal direction of the smoking substance portion. In this case, the durability of the odor improvement effect of sidestream smoke may be increased.

According to one embodiment of the present invention, the sheet leaf cut filler having a length longer than the diameter of the smoking material part covers 70% or more, specifically 75% or more, more specifically 80% or more in the longitudinal direction of the smoking material part. Here, “covering 70% or more, or 75% or more, or 80% or more in the longitudinal direction” means 70% or more, or 75% or more, or 80% or more when considering the total length of the smoking substance part as 100%. means that a particular substance exists in “A specific material exists” means that a specific material is found in a cross section perpendicular to the length direction. The above-described long sheet cut filler may cover the lengthwise direction of the smoking substance part with one or more sheet cut filler, and cover the widest possible range even with a small amount only when the sheet cut filler is arranged so as not to overlap in the length direction. can do. When the planar cut filler containing the spice covers 70% or more of the smoking material portion in the longitudinal direction, the user can continuously feel the odor improvement effect of sidestream smoke until smoking is completed.

The filter unit 20 is disposed downstream of the smoking material unit 10 and serves as a filter through which the aerosol generated from the smoking material unit 10 passes immediately before the user inhales it. The filter unit 20 may be formed of various materials, for example, the filter unit 20 may be a cellulose acetate filter. The filter unit 20 may be a cellulose acetate filter in which fragrance materials are not flavored or a TJNS (transfer jet nozzle system) filter in which fragrance materials are flavored.

According to one embodiment of the present invention, the filter unit 20 may be a tube-shaped structure including a hollow therein. The filter unit 20 may be manufactured by inserting a structure such as a film or a tube made of the same or different material into the inside (eg, hollow). Although the filter unit 20 according to one embodiment of the present invention is shown in FIG. 1 as being a mono filter composed of a single filter, it is not limited thereto. For example, it is natural that the filter unit 20 may be provided with a dual filter or a triple filter having two acetate filters to increase filter efficiency. In addition, although not shown, a crushable capsule (not shown) having a structure in which an inner liquid containing a fragrance is wrapped with a film may be included inside the filter unit 20 .

The outside of the smoking substance part 10 and the filter part 20 may be wrapped by a wrapper 30a or 30b.

The smoking substance portion 10 may be wrapped by a smoking substance portion wrapper 30a. Some of the cigarette smoke generated in the combustion 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 the sidestream smoke gives secondhand smokers an unpleasant feeling. Various attempts have been made, such as adding fillers such as magnesium oxide, titanium oxide, cerium oxide, aluminum oxide, calcium carbonate, zirconium carbonate, etc. to cigarette paper for reducing sidestream smoke, but simply applying these fillers to reduce sidestream smoke gives a feeling of smoking. It has been difficult to solve the above problems through an appropriate combination of materials entering the filler, due to deterioration, burning off, or deterioration of retrograde integrity. The smoking material part wrapper 30a according to one embodiment of the present invention is magnesium oxide (MgO and/or Mg(OH) ₂ ) and calcium carbonate in order to reduce sidestream smoke and at the same time prevent a burning sensation, a deterioration in retrograde consistency, and burnout. (CaCO ₃ ) is applied as a mixed filler.

The filter unit 20 may be wrapped by a filter unit wrapper 30b. The filter unit wrapper 30b may be made of paper having oil resistance, and aluminum foil may be further included on the inner surface of the filter unit wrapper 30b.

The smoking substance portion 10 wrapped by the smoking substance portion wrapper 30a and the filter portion 20 wrapped by the filter portion wrapper 30b may be combined and packaged by the tip paper 40 . As shown in FIG. 1 , the tip paper 40 may be wrapped around at least a portion of the smoking material wrapper 30a (for example, a downstream portion) and the outside of the filter wrapper 30b. In other words, at least a portion of the smoking substance unit 10 and the filter unit 20 are further wrapped by the tip paper 40 and may be physically coupled. According to one embodiment of the present invention, the tip paper 40 may be made of non-porous paper that is not oil-resistant, but is not limited thereto. In addition, the tip paper 40 may prevent the filter unit 20 from burning by including an incombustible material, but is not limited thereto.
