Description

Technical Field

[0001] This invention relates to a woven filter rod including flavored sheets and a smoking article including the filter rod. Background Technology

[0002] For heated tobacco sticks, specialized equipment is required to heat the medium (including tobacco and other cigarette raw materials, flavorings, and aerosols) to release the smoke flavor. Existing equipment for heating tobacco sticks designed to release smoke flavor incorporates temperature programs to achieve high-temperature heating, taking into account heat transfer to the medium. The heating temperature is typically maintained between 200°C and 400°C. Unlike traditional cigarettes inhaled by burning tobacco, heating the medium in a heated tobacco stick can generate a large amount of water vapor. The internal heating temperature of the medium is approximately 100°C to 200°C. The airflow generated within the medium also maintains a corresponding temperature; therefore, if no cooling material is provided downstream of the medium, the smoker will inhale hot air.

[0003] Currently, polymeric materials (PLA, CA, PET, etc.) that can absorb heat from the airflow and undergo a phase change are used as cooling materials for heated smoke rods. These materials are applied to the entire cross-section of the filter rod by forming them into a woven structure. However, products made by spinning and weaving PLA are already on the market, but these are not only expensive but also have low unit yield and production efficiency.

[0004] Therefore, a cooling material is being actively developed to improve the economy and functionality of the new type of heated smoke rod. Summary of the Invention

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, detailed descriptions of relevant well-known functions or structures are omitted where it would unnecessarily obscure the essence of the invention. Furthermore, the terminology used in this specification to accurately describe embodiments may vary depending on the intent of the user or operator or the conventions of the technical field to which this invention pertains. Therefore, the definitions of terminology should be based on the overall content of the specification. The same reference numerals in the various drawings denote the same parts.

[0031] Throughout the instruction manual, when it is stated that a component is "on" another component, this includes not only cases where one component is in contact with another component, but also cases where another component exists between the two components.

[0032] Throughout the specification, when stating that a part "includes" a certain component, it may also include other components rather than excluding the possibility of the existence of other components.

[0033] The woven filter rod of the present invention and smoking articles including the woven filter rod will be described in detail below with reference to embodiments and accompanying drawings. However, the present invention is not limited to these embodiments and drawings.

[0034] The present invention relates to a woven filter rod, which can be used in smoking products and includes flavored fiber, the flavored fiber comprising fibers cut from flavored flakes.

[0035] According to one embodiment of the present invention, the flavored sheet comprises a cellulose-based polymer, a plasticizer, and a flavoring substance. The flavored sheet is in the form of a film, and the flavoring substance is contained within the cellulose-based polymer, thereby improving the persistence of the transferred aroma and / or cigarette flavor in smoking products. Furthermore, for example, in smoking products such as cigarette sticks, the cellulose-based polymer undergoes a phase transition (crystallization) only at the temperature (high temperature) of the airflow moving towards the smoker, thus providing an airflow cooling effect. Moreover, since the flavored sheet has high tensile strength and flexibility, it does not need to be coated on a base paper and can be used itself as part of a fibrous phase filter rod.

[0036] According to one embodiment of the present invention, the "smoking article" can be any inhalable product or any product that provides a smoking experience, regardless of whether it is based on cigarettes, tobacco derivatives, expanded tobacco, reconstituted tobacco, or cigarette substitutes. For example, the smoking article can refer to an inhalable product capable of generating an aerosol, such as cigarettes, cigars, cigarillos, electronic cigarettes (e.g., heated electronic cigarettes). The smoking article may include aerosol-generating substances or aerosol-generating matrices. Furthermore, the smoking article may include solid substances based on tobacco raw materials such as reconstituted tobacco, shredded tobacco, and recycled tobacco. Alternatively, the smoking article may include volatile compounds.

[0037] According to one embodiment of the invention, the cellulose-based polymer can be an adhesive material, while also providing a polymer matrix for forming a sheet that retains flavor substances, is flexible, and has high tensile strength. For example, the cellulose-based polymer can also be used with solvents (e.g., water) and alcohols used to dissolve and / or disperse components used for film formation and / or sheet formation. For example, it can include at least one selected from the group consisting of methylcellulose, ethylcellulose, carboxymethylcellulose, carboxyethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxyethylmethylcellulose, and agar, but is not limited thereto. Preferably, it can be methylcellulose and hydroxypropylmethylcellulose.

[0038] According to one embodiment of the present invention, the cellulose-based polymer is 20% to 60% by weight, 20% to 50% by weight, or 30% to 40% by weight of the flavored sheet. When the content of the cellulose-based polymer is less than 20% by weight, it is difficult to have sufficient tensile strength and flexibility to be used as part of a woven filter rod, or it is also difficult to make into a sheet. When it exceeds 60% by weight, the sheet will undergo physical changes (e.g., breakage or cracking), and the flavor substances in the sheet cannot release the flavor well, making it difficult to improve the cigarette flavor and the persistence of the smoking taste.

[0039] According to one embodiment of the present invention, the flavoring substance can release fragrance and / or impart fragrance properties, or can improve the smell of smoking, and any flavoring substance that can be used in smoking articles can be used without limitation, including at least one of the following groups: organic acids selected from lactic acid, citric acid, malic acid, etc.; licorice; sucrose; fructose syrup; isosweet; cocoa; lavender; cinnamon; cardamom; celery; fenugreek; sage; sandalwood; bergamot; geranium; honey extract; rose oil; vanilla; lemon oil; orange oil; peppermint oil; cinnamon; parsley seed; cognac; jasmine; chamomile; menthol; cinnamon; ylang-ylang; salvia; spearmint; ginger; coriander; clove extract (or clove substance); and coffee, but is not limited thereto.

[0040] According to one embodiment of the present invention, the flavoring substance is 10% to 50% by weight, 10% to 40% by weight, 10% to 30% by weight, or 10% to 20% by weight of the flavoring tablet. When it is within the above range, the persistence of the transferred flavor and / or cigarette flavor can be improved, a high concentration can be achieved, and the flavor and / or flavor intensity can be adjusted by adding concentration.

[0041] According to one embodiment of the present invention, the plasticizer may include at least one selected from the group consisting of propylene glycol, polyethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, glycerol, and sorbitol, but is not limited thereto. Preferably, it may be propylene glycol and glycerol.

[0042] According to one embodiment of the present invention, in order to adjust the hardness of the fragrance sheet, the plasticizer is 1% to 20% by weight, 1% to 15% by weight, 1% to 10% by weight, or 5% to 10% by weight of the fragrance sheet. When the content of the plasticizer is less than 1% by weight, it is difficult to have suitable tensile strength for use as a component of woven filter rods. When the content of the plasticizer exceeds 20% by weight, the sheet is prone to tearing due to poor physical properties (e.g., too low tensile strength or too soft), making it difficult to manufacture or use as fragrance sheet fibers for woven filter rods.

[0043] According to one embodiment of the present invention, the thickness of the fragrance sheet is less than 1 mm, 0.1 mm to 1 mm, or 0.5 mm to 0.8 mm, and the fragrance sheet can be cut into fragrance sheet fibers. When the thickness of the fragrance sheet exceeds 1 mm, the flexibility of the sheet cannot be well achieved, making it difficult to make a woven filter rod, and the fragrance cannot be released well due to the increased thickness; if the fragrance sheet is too thin, the cooling effect may not be achieved.

[0044] According to one embodiment of the present invention, the scented sheet has sufficient tensile strength to be used as part of a woven filter rod. For example, the tensile strength of the scented sheet is 1.0 kgf / 15 mm or more, 2.0 kgf / 15 mm or more, 5.0 kgf / 15 mm or more, or 1.0 kgf / 15 mm to 10 kgf / 15 mm. When the tensile strength is within the above range, a scented sheet with a balance of hardness and flexibility suitable for use in woven filter rods can be provided.

[0045] According to one embodiment of the present invention, the average diameter (i.e., thickness) of the fragranced sheet fibers can be less than 1 mm, 0.1 mm to 1 mm, or 0.5 mm to 0.8 mm. When the average diameter of the fragranced sheet exceeds 1 mm, it is difficult to achieve flexibility and thus cannot be made into a woven filter rod, and the increased thickness will prevent the fragrance from being released effectively; if the fragranced sheet is too thin, a cooling effect may not be achieved.

[0046] According to one embodiment of the present invention, without departing from the purpose of the present invention, the shape, thickness, length, etc. of the woven filter rod can be changed according to the smoking product. For example, when used as a filter rod for cigarettes or electronic cigarettes, the diameter of the woven filter rod can be 4.5 mm to 8 mm, the circumference can be 14 mm to 25 mm, and the length can be 5 mm to 20 mm.

[0047] This invention relates to smoking articles including the woven filter rod of this invention.

[0048] According to one embodiment of the present invention, the smoking article may include a filter rod portion and a smoking substance portion. A cooling and aroma-releasing effect is provided by introducing a woven filter rod with flavoring fibers suitable for the present invention. The filter rod portion includes the woven filter rod. For example, the filter rod portion may be a single-shaped filter rod, a two-piece filter rod, or a three-piece filter rod. For example, the filter rod portion may include at least one of a porous matrix structure filter rod, a tubular structure filter rod, and a paper tube filter rod.

[0049] According to one embodiment of the present invention, the two-piece filter rod may include a first filter rod and a second filter rod including a woven structure filter rod of the present invention. According to one embodiment of the present invention, the three-piece filter rod may include a first filter rod, a second filter rod including a woven structure filter rod of the present invention, and a third filter rod including a tubular filter rod or a paper tube filter rod; or it may include a first filter rod, a second filter rod including a tubular filter rod or a paper tube filter rod, and a third filter rod including a woven structure filter rod of the present invention. For example, in a heated tobacco stick, the first filter rod is located in the direction closer to the smoker (downstream direction), and the second and third filter rods are sequentially located in the direction farther from the smoker (upstream direction).

[0050] According to one embodiment of the present invention, the woven filter rod includes flavored sheet fibers, which comprise fibers cut from flavored sheets. According to another embodiment of the present invention, the flavored sheet comprises a cellulose-based polymer, a plasticizer, and a flavoring substance. The flavored sheet is in the form of a film, containing the flavoring substance within the cellulose-based polymer, thereby improving the persistence of the transferred aroma and / or cigarette flavor in smoking products. Furthermore, for example, in smoking products such as cigarette sticks, the cellulose-based polymer undergoes a phase transition (crystallization) only at the temperature (high temperature) of the airflow moving towards the smoker, thus providing an airflow cooling effect. Moreover, since the flavored sheet has high tensile strength and flexibility, it does not need to be coated on the base paper and can be used itself as part of the fibrous phase filter rod.

[0051] According to one embodiment of the present invention, the cellulose-based polymer can be an adhesive material, and also provides a polymer matrix for forming a sheet that retains flavor substances, is flexible, and has high tensile strength. For example, it can include at least one selected from the group consisting of methylcellulose, ethylcellulose, carboxymethylcellulose, carboxyethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxyethylmethylcellulose, and agar, but is not limited thereto. Preferably, it can be methylcellulose and hydroxypropylmethylcellulose.

[0052] According to one embodiment of the present invention, the cellulose-based polymer is 20% to 60% by weight, 20% to 50% by weight, or 30% to 40% by weight of the flavored sheet. When the content of the cellulose-based polymer is less than 20% by weight, it is difficult to have sufficient tensile strength and flexibility to be used as part of a woven filter rod, or it is also difficult to make into a sheet. When it exceeds 60% by weight, the sheet will undergo physical changes (e.g., breakage or cracking), and the flavor substances in the sheet cannot release the flavor well, making it difficult to improve the cigarette flavor and the persistence of the smoking taste.

[0053] According to one embodiment of the present invention, the flavoring substance may impart fragrance and / or aroma properties, or may enhance the flavor of smoking, and any flavoring substance that can be used in smoking articles may be used without limitation, including at least one of the following groups: organic acids selected from lactic acid, citric acid, malic acid, etc.; licorice; sucrose; fructose syrup; isosweet; cocoa; lavender; cinnamon; cardamom; celery; fenugreek; sage; sandalwood; bergamot; geranium; honey extract; rose oil; vanilla; lemon oil; orange oil; peppermint oil; cinnamon; parsley seed; cognac; jasmine; chamomile; menthol; cinnamon; ylang-ylang; tanshinone; spearmint; ginger; coriander; clove extract (or clove substance); and coffee, but is not limited thereto.

[0054] According to one embodiment of the present invention, the flavoring substance is 10% to 50% by weight, 10% to 40% by weight, 10% to 30% by weight, or 10% to 20% by weight of the flavoring tablet. When it is within the above range, the persistence of the transferred flavor and / or cigarette flavor can be improved, a high concentration can be achieved, and the flavor and / or flavor intensity can be adjusted by adding concentration.

[0055] According to one embodiment of the present invention, the plasticizer may include at least one selected from the group consisting of propylene glycol, polyethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, glycerol, and sorbitol, but is not limited thereto. Preferably, it may be propylene glycol and glycerol.

[0056] According to one embodiment of the present invention, in order to adjust the hardness of the fragrance sheet, the plasticizer is 1% to 20% by weight, 1% to 15% by weight, 1% to 10% by weight, or 5% to 10% by weight of the fragrance sheet. When the content of the plasticizer is less than 1% by weight, it is difficult to have suitable tensile strength for use as part of a woven filter rod. When the content of the plasticizer exceeds 20% by weight, the sheet is prone to tearing due to poor physical properties (e.g., too low tensile strength or too soft), making it difficult to manufacture or use as fragrance sheet fibers in a woven filter rod.

[0057] According to one embodiment of the present invention, the thickness of the fragrance sheet is less than 1 mm, 0.1 mm to 1 mm, or 0.5 mm to 0.8 mm, and the fragrance sheet can be cut into fragrance sheet fibers. When the thickness of the fragrance sheet exceeds 1 mm, the flexibility of the sheet cannot be well achieved, making it difficult to make a woven filter rod, and the fragrance cannot be released well due to the increased thickness; if the fragrance sheet is too thin, the cooling effect may not be achieved.

[0058] According to one embodiment of the present invention, the scented sheet has sufficient tensile strength to be used as part of a woven filter rod. For example, the tensile strength of the scented sheet is 1.0 kgf / 15 mm or more, 2.0 kgf / 15 mm or more, 5.0 kgf / 15 mm or more, or 1.0 kgf / 15 mm to 10 kgf / 15 mm. When the tensile strength is within the above range, a scented sheet with a balance of hardness and flexibility suitable for use in woven filter rods can be provided.

[0059] According to one embodiment of the present invention, the average diameter (i.e., thickness) of the fragranced sheet fibers can be less than 1 mm, 0.1 mm to 1 mm, or 0.5 mm to 0.8 mm. When the average diameter of the fragranced sheet exceeds 1 mm, it is difficult to achieve flexibility and thus cannot be made into a woven filter rod, and the increased thickness will prevent the fragrance from being released effectively; if the fragranced sheet is too thin, a cooling effect may not be achieved.
