Description

Non-combustion flavor-generating products

[0001] The present invention relates to a non-combustion flavor generating article.

[0002] Non-combustion flavor-generating articles use wrappers made of paper. For example, Patent Document 1 discloses an article for use in a non-combustion aerosol delivery system, the article having a wrapper including a cellulose-based material having a basis weight of more than about 40 grams per square meter. The article is said to be highly resistant to wrinkling or other deformation when inserted into a heating device. Furthermore, Patent Document 2 discloses wrapper paper containing 70 to 95% by weight of pulp fibers. The wrapper paper is said to be heat-resistant or flame-retardant and to have advantageous properties taking into consideration strength, processability, biodegradability, and impact on taste.

[0003] Special table 2023-530900 publication Special table 2023-532249 publication

[0004] Non-combustion flavor-generating articles are required to have strength so that they will not break when inserted into a heating device. This strength is largely dependent on the strength of the wrapper. Furthermore, to improve the appearance of non-combustion flavor-generating articles, the wrapper must have high opacity. It is generally known that increasing the filler content improves the opacity of paper. However, as the filler content increases, the strength of the paper decreases. Thus, there is a trade-off between paper strength and opacity. The inventors conceived the idea that if a wrapper that combines both high strength and high opacity could be provided, a non-combustion flavor-generating article with high strength and excellent appearance could be provided. In view of these circumstances, an object of the present invention is to provide a non-combustion flavor-generating article with high strength and excellent appearance.

[0005] The above-mentioned problems are solved by the following: Aspect 1 A flavor source rod, a cooling section, and a filter section are provided, the flavor source rod has a wrapper containing pulp and a filler, and the pulp in the wrapper has a basis weight of 40 g / m 2 or more, and the basis weight of the filler is 3.9 g / m 2Aspect 2: The non-burning flavor generating article according to Aspect 1, wherein the wrapper has a thickness of 7.0 to 9.0 (mm / 100).

[0008] In this disclosure, "X to Y" includes the end values ​​X and Y. Unless otherwise specified, the weight is the weight after storage for two days or more in an environment of 22°C and 60% relative humidity. In addition, in non-combustion flavor-generating articles, downstream refers to the direction toward the mouthpiece end.

[0009] 1. Non-burning Flavor-Generating Article The non-burning flavor-generating article of this embodiment comprises a flavor source rod, a cooling section, and a filter section. The flavor source rod comprises a wrapper containing pulp and a filler, and the basis weight of the pulp in the wrapper is 40 g / m. 2 or more, and the basis weight of the filler is 3.9 g / m 2 That's all. It is preferable that a cooling section is located downstream of the flavor source rod, and a filter section is located downstream of the cooling section. The size of the non-combustion flavor-generating product is not limited. Preferably, the length is about 50 to 80 mm, and the cross-sectional diameter is about 5.5 to 7.5 mm. In one embodiment, the basis weight of the paper is measured in accordance with JIS P 8124. However, if a sufficiently large test piece cannot be prepared, a smaller test piece may be used. For other measurements, if a sufficiently large test piece cannot be prepared, a smaller test piece may also be used.

[0010] 1-1. First Aspect Fig. 1 shows a first aspect of a non-burning flavor-generating article. In the figure, 100 is a non-burning flavor-generating article, 1 is a flavor source rod, 3 is a cooling section, 5 is a filter section, 51 is a first segment, 52 is a second segment, and V is ventilation. 20 contains pulp and filler, and the basis weight of the pulp is 40 g / m 2 or more, and the basis weight of the filler is 3.9 g / m 2 That's the wrapper. 40 is tipping paper.

[0011] (1) Flavor Source Rod 1 [Wrapper] As will be described in detail below, the wrapper 20 has both high strength and high opacity. Therefore, the flavor source contained in the flavor source rod 1 equipped with the wrapper 20 is not visible through the wrapper, and the flavor source has a good appearance. Furthermore, the non-combustion flavor generating article 100 equipped with the flavor source rod 1 is less likely to deform or break even when external forces are applied during use or transportation. Conventional non-combustion flavor generating articles are prone to breaking or breakage when inserted into a heating device and heated, but the non-combustion flavor generating article 100 of the present embodiment can avoid such problems.

[0012] 1) Basis Weight The flavor source rod 1 is a substantially cylindrical member for generating flavor components contained in a flavor source such as a tobacco raw material. The flavor source rod 1 comprises a flavor source and a wrapper 20 wrapped around the flavor source. The wrapper 20 in this embodiment contains pulp and a filler, and the basis weight of the pulp is 40 g / m 2 or more, and the basis weight of the filler is 3.9 g / m 2 That is all. If the basis weight of the pulp is less than this value, the strength of the paper is insufficient. If the basis weight of the filler is less than this value, the opacity of the paper is insufficient. It has been known that there is a trade-off between the strength and opacity of paper, but if the basis weight of the pulp and the basis weight of the filler are within the above ranges, both high strength and high opacity can be achieved. From this perspective, the lower limit of the basis weight of the pulp is preferably 41 g / m 2 The lower limit of the basis weight of the filler is preferably 7 g / m 2 That's all.

[0013] However, if the basis weight of the pulp is too high, the rigidity of the paper becomes too high, which may reduce the workability in the production of flavor source rods (hereinafter also referred to as "suitability for winding"). From this viewpoint, the basis weight of the pulp is preferably 55 g / m 2 In addition, if the basis weight of the filler is too high, the paper may become brittle. From this viewpoint, the basis weight of the filler is preferably 9 g / m 2 Therefore, the basis weight of the pulp is preferably 41 to 55 g / m 2 The basis weight of the filler is preferably 7 to 9 g / m 2 is.

[0014] The basis weight of the pulp and the basis weight of the filler can be determined as follows: 1) Measure the basis weight of the wrapper. If the wrapper contains a coating layer, measure the basis weight of the paper after removing the coating layer according to a standard method. The basis weight determined in this step is designated as B. 2) Calculate the filler content of the wrapper. The filler content is determined by measuring the crude ash content according to a standard method. 3) Calculate the pulp content of the wrapper. The pulp content is determined by subtracting the crude ash content from the weight of the paper after removing the coating layer. 4) Divide basis weight B proportionally by the filler content and the pulp content to determine the basis weight of the pulp and the basis weight of the filler. Multiple heating temperatures may be set when determining the crude ash content, depending on the thermal decomposition temperature of the filler. For example, if calcium carbonate accounts for the majority of the filler, the temperature may be 400°C.

[0015] The basis weight of the wrapper is preferably 50 to 70 g / m 2 , more preferably 50 to 65 g / m 2 The basis weight of the wrapper is the sum of the basis weight of the base paper and the basis weight of the coating layer.

[0016] 2) Opacity From the viewpoint of improving the appearance, the opacity of the wrapper 20 is preferably 70% or more, more preferably 75%, and even more preferably 78% or more. There is no upper limit, but in one embodiment, it is 80% or less. That is, the opacity of the wrapper 20 is preferably 70 to 80%, 75 to 80%, or 70 to 78%.

[0017] Opacity is measured in accordance with JIS P 8149. JIS P 8149 requires a sample piece measuring approximately 75 mm x 150 mm. However, if a sample piece of this size cannot be prepared, a jig for fixing the sample may be used. The jig is preferably made of black metal and is constructed of a material that does not transmit or reflect light.

[0018] 3) Tensile Strength: From the viewpoint of providing a non-combustion flavor-generating article with excellent strength, it is preferable that the tensile strength (MD) of the wrapper 20 be high. However, if the tensile strength is too high, the suitability for rolling may be reduced. From this viewpoint, the tensile strength is preferably 50 to 68 N / 15 mm. The tensile strength is measured in accordance with JIS P 8113.

[0019] 4) Rigidity The rigidity of the wrapper 20 is evaluated by loop stiffness. The loop stiffness of the wrapper 20 is preferably 11 g or less. A loop stiffness value in this range results in excellent winding suitability. Loop stiffness is measured as follows. Using a Loop Stiffness Tester (registered trademark) DA manufactured by Toyo Seiki Seisakusho, Ltd., a sample deformed into a loop shape is compressed in the radial direction of the loop to measure the stress. The sample width is 25 mm, and the compression speed is 3.3 mm / s.

[0020] 5) Diffusivity The diffusivity of the wrapper 20 is preferably 1 cm / s or less, and more preferably 0.2 cm / s or less. Diffusivity is an indicator of the diffusivity of a substance, particularly a gas, and having a diffusivity in this range for the wrapper 20 improves the flame retardancy of the wrapper. Diffusivity is measured in accordance with CRM No. 77.

[0021] 6) Thickness The thickness of the wrapper 20 is preferably 7.0 to 9.0 (mm / 100), more preferably 7.2 to 8.6 (mm / 100), and even more preferably 7.2 to 7.8 (mm / 100). If the wrapper is too thick, the opacity tends to be high, but the thermal conductivity and roll-up suitability may be reduced. The thickness is measured in accordance with JIS P 8118.

[0022] 7) Coating Layer From the viewpoint of reducing staining, the wrapper 20 may have a coating layer. The basis weight of the coating layer is preferably 3 to 10 g / m 2 , more preferably 5 to 8 g / m 2The basis weight of the coating layer is determined by the weight of the coating layer, which is determined by the difference between the weight of the wrapper before coating and the weight of the wrapper after coating. The weight of the wrapper before coating may be estimated as the weight of the wrapper after coating with the coating layer removed.

[0023] The material constituting the coating layer is not limited, but the following materials are preferred from the viewpoint of minimizing the impact on flavor and taste: alginic acid and its salts (e.g., sodium salts); polysaccharides such as pectin, guar gum, and gum arabic; cellulose derivatives such as ethyl cellulose, methyl cellulose, carboxymethyl cellulose, and nitrocellulose; and starch and its derivatives. Examples of starch and its derivatives include ether derivatives such as carboxymethyl starch, hydroxyalkyl starch, and cationic starch; and ester derivatives such as starch acetate, starch phosphate, and starch octenyl succinate. Gum arabic, pectin, or starch is particularly preferred. The flavor source is preferably wrapped around the wrapper 20 so that the coating layer is positioned inside the wrapper 20. Positioning the coating layer inside the wrapper 20 can prevent the spread of stains.

[0024] 8) Wrapping Region It is preferable that 60% or more of the circumferential area of ​​the flavor source rod 1 is wrapped with the wrapper 20. The ratio W / T of the area W wrapped with the wrapper 20 to the total circumferential area T of the flavor source rod 1 is preferably 60 to 100%, 70 to 100%, or 75 to 100%. When W / T is 60% or more, sufficient strength is achieved without using another wrapper. Therefore, in a more preferred embodiment, the area W is wrapped with only the wrapper 20. As shown in FIG. 1 , the wrapper 20 may be present continuously around the circumferential area of ​​the flavor source rod 1. Alternatively, the wrapper 20 may be present discontinuously around the circumferential area of ​​the flavor source rod 1. Examples of the wrapper 20 present discontinuously around the circumferential area of ​​the flavor source rod 1 include the following: An embodiment in which the wrapper 20 is present in stripes such that the longitudinal direction of the wrapper 20 presence area is approximately parallel to the longitudinal direction of the flavor source rod 1. An embodiment in which the wrapper 20 is present in a striped pattern with the longitudinal direction of the wrapper 20 being approximately parallel to the circumferential direction of the flavor source rod 1. An embodiment in which the wrapper 20 is present in a spiral pattern extending in the longitudinal direction of the flavor source rod 1. However, from the standpoint of manufacturing efficiency, etc., it is preferable that the wrapper 20 be present continuously around the lateral circumference of the flavor source rod 1.

[0025] [Flavor Source] The shape of the flavor source filled in the wrapper is not limited, and examples thereof include a sheet, the sheet cut into widths of 0.8 to 1.2 mm, or cut pieces cut into widths of 0.8 to 1.2 mm. The sheet may be gathered, folded, or spirally wound without being cut, and then filled into the wrapper to form a flavor source rod. Alternatively, the sheet may be cut into strips and then filled concentrically into the wrapper to form a flavor source rod. Alternatively, the sheet may be cut into strips and then filled so that the longitudinal direction of the strips is parallel to the longitudinal direction of the flavor source rod to form a flavor source rod.

[0026] The packing density of the flavor source is not particularly limited, but is usually 200 to 800 mg / cm from the viewpoint of ensuring the characteristics of the non-combustion flavor-generating product and imparting a good flavor and smoking taste. 3 and preferably 250 to 600 mg / cm 3The length of the flavor source rod is not limited, but is preferably 10 to 25 mm. The diameter is also not limited, but is preferably 6 to 8 mm.

[0027] The flavor source may generate steam when heated. The heating temperature is not limited, but is about 30 to 400°C. To promote the generation of aerosol, an aerosol source such as glycerin, propylene glycol, 1,3-butanediol, or other polyol may be added to the flavor source. The amount of the aerosol source added is preferably 5 to 50 wt %, more preferably 10 to 30 wt %, based on the dry weight of the flavor source. Examples of flavor sources include tobacco-derived tobacco materials and materials in which flavors are supported on a carrier. Of these, the flavor source is preferably a tobacco material. Known flavors can also be added to the tobacco material.

[0028] (2) Cooling Section The cooling section 3 is adjacent to the downstream side of the flavor source rod 1. "Downstream" refers to the direction toward the mouthpiece end. The cooling section 3 is a component for promoting aerosolization by cooling flavor components and vapor generated in the flavor source rod 1. The cooling section 3 may be a hollow paper tube. The paper tube is preferably made of cardboard, which is more rigid than tipping paper. The paper tube may be provided with ventilation V (openings). Multiple ventilations are preferably provided along the circumference of the paper tube. The cooling section 3 may also be filled with a gathered sheet to improve heat exchange efficiency. The dimensions of the cooling section 3 are not limited, but the length is preferably 10 to 25 mm and the diameter is preferably 5.5 to 7.5 mm. The tipping paper may be made of known paper.

[0029] (3) Filter Section In this embodiment, the filter section 5 includes a first segment 51 and a second segment 52. The first segment 51 is preferably a solid filter, and may be, for example, an acetate filter. The second segment 52 may be a center-hole filter, and may be, for example, a hollow acetate filter. The dimensions of the filter section 5 are not limited, but the length is preferably 15 to 30 mm, and the diameter is preferably 5.5 to 7.5 mm. The length of the first segment 51 is preferably 5 to 10 mm, and the length of the second segment 52 is preferably 10 to 20 mm.

[0030] In this embodiment, the first segment 51 is wrapped with an inner plug wrapper 61. The first segment 51 and the second segment 52 are wrapped with and joined together with an outer plug wrapper 62. Furthermore, the filter section 5 and the cooling section 3 are joined together with tipping paper 40. The inner plug wrapper and the outer plug wrapper may be made of known paper.

[0031] 1-2. Second Aspect FIG. 2 shows a second aspect of the combustion-type flavor-generating article 100. In the figure, 9 is a tip plug and 42 is a second tipping paper. Other symbols are defined the same as in FIG. 1. The tip plug 9 is provided to impart a function. For example, the tip plug 9 can be a solid filter. In this case, it is possible to prevent the flavor source from falling off the tip of the combustion-type flavor-generating article 100. Furthermore, if a flavoring agent is carried on the tip plug 9, it is also possible to deliver the flavor. The second tipping paper may be made of known paper.

[0032] In this embodiment, the tip plug 9 and the flavor source rod 1 are wrapped and joined with the wrapper 20. The tip plug 9, the flavor source rod 1, and the cooling section 3 are then joined with the second tipping paper 42. The wrapper 20 exists across the joint between the tip plug 9 and the flavor source rod 1, thereby increasing the strength of the joint. While conventional combustion-type flavor-generating articles are prone to breakage at the joint between components, the combustion-type flavor-generating article 100 of this embodiment avoids such problems. The second embodiment differs from the first embodiment in that it includes the tip plug 9 and the wrapping, but is otherwise the same as the first embodiment. Generally, the term "wrapper" is often used to refer to a material that wraps one component, but in the present disclosure, the term "wrapper" refers to a material that wraps one or more components.

[0033] 1-3. Third Embodiment Figure 3 shows a third embodiment of the combustion-type flavor-generating article 100. The symbols in the figure are defined the same as in Figure 2. In this embodiment, the tip plug 9 and the flavor source rod 1 are wrapped and joined with the second tipping paper 42. The tip plug 9, the flavor source rod 1, and the cooling section 3 are then joined with the wrapper 20. In this embodiment, the wrapper 20 also straddles the joint between the tip plug 9 and the flavor source rod 1, thereby increasing the strength of the joint. The third embodiment differs from the second embodiment in terms of the wrapping, but is otherwise the same as the second embodiment.

[0034] 1-4. Fourth Embodiment Figure 4 shows a fourth embodiment of the combustion-type flavor-generating article 100. The symbols in the figure are defined the same as in Figure 2. In this embodiment, the tip plug 9 is wrapped with a second wrapper 22, and the flavor source rod 1 is wrapped with a wrapper 20. The tip plug 9, the flavor source rod 1, and the cooling portion 3 are joined together with a second tipping paper 42. The second wrapper 22 may be made of a known paper different from the wrapper 20, or may be made of the same paper as the wrapper 20. The fourth embodiment differs from the second embodiment in terms of wrapping, but is otherwise the same as the second embodiment.

[0035] 1-5. Fifth Aspect FIG. 5 shows a fifth aspect of the combustion-type flavor-generating article 100. The symbols in the figure are defined the same as those in FIG. 2. In this embodiment, the tip plug 9 is wrapped with a second wrapper 22, and the flavor source rod is wrapped with a third wrapper 23. The tip plug 9, the flavor source rod 1, and the cooling section 3 are joined together with a wrapper 20. The second wrapper may be made of the same paper as the wrapper 20. The second wrapper may be made of paper having a lower pulp basis weight than the wrapper 20. The third wrapper 23 may be made of a known paper different from the wrapper 20, or may be made of the same paper as the wrapper 20. The third wrapper 23 may also be made of paper having a lower pulp basis weight than the wrapper 20. By making the second wrapper 22 and the third wrapper 22 out of paper having a lower pulp basis weight than the wrapper 20, manufacturability is maintained. The fifth aspect differs from the second aspect in terms of wrapping, but is otherwise the same as the second aspect.

[0036] 2. Non-Combustion Flavor Generating System The combination of a non-combustion flavor generating article and a heating unit is also called a non-combustion flavor generating system. Figure 6 shows one embodiment of this system. In the figure, 100 is a non-combustion flavor generating article, and 30 is a heating unit equipped with a heater. The heating unit includes a heater, a housing, a power source, etc.

[0037] The heater preferably electrically heats the flavor source rod 1. A heater that heats from the outer periphery of the flavor source rod 1 (external heating system) can be used. Alternatively, a heater that is inserted into the flavor source rod 1 and heats from the inside can also be used. In particular, the non-combustion flavor-generating article according to this embodiment has the remarkable effect of preventing the flavor source rod 1 from breaking when using the external heating system.

[0038] The non-combustion flavor generating system may also be an induction heating (IH) system. In this embodiment, the heating unit 30 is configured with an induction coil.

Examples 5 and 6 were rated as B because no punctures occurred at 2,500 rods / min, but rods with weak glue were produced at 2,700 rods / min.

[0051] [Diffusivity] Measured in accordance with CRM No. 77.

[0052] [Bending Strength] Figure 8 shows an outline of the measurement method. A paper tube X with a length of 15.5 mm and a paper tube Y with a length of 44.5 mm were prepared. Both were wrapped with the paper (wrapper) to prepare a pseudo-rod sample 200 in which the paper tubes X and Y were connected. The connection J between the paper tubes X and Y was heated at 295°C for 5 minutes. The connection J was fixed on the stage S so that it served as a fulcrum, and the end face of the paper tube X was pressed down with a plunger P to break the sample at the connection J. The stress at this time was taken as the breaking strength.
