Abstract
A cigarette packaging material includes: a packaging material having an inner bottom surface and defining a housing space above the inner bottom surface, the housing space housing a cigarette such that a longitudinal direction of the cigarette is substantially parallel with a depth direction of the housing space; and a humidity control layer housed in the housing space, disposed along the inner bottom surface, brought into direct contact with the cigarette, and dehumidifying and humidifying the cigarette to control humidity of the cigarette to reach a target humidity.
Description
- The present disclosure relates to a cigarette packaging material and a cigarette product. The present application claims priority from Japanese Patent Application JP2021-121773 filed on Jul. 26, 2021, the content of which is hereby incorporated by reference into this application.
- It is said that a proper humidity of tobacco leaf is approximately 70% RH.
- If humidity of tobacco leaf is lower than the proper humidity, the tobacco leaf burns at high temperature, and the cigarette tastes bad for the smoker. Whereas, if humidity of tobacco leaf is higher than the proper humidity, mold grows on the tobacco leaf.
-
Patent Document 1 discloses a cigarette case (see paragraph [0028]). In the cigarette case, water vapor released from a water-absorbing sponge provides moisture throughout a cigarette housed in the cigarette case (see paragraph [0048]). -
-
- Patent Document: Japanese Unexamined Patent Application Publication No. 2019-031322
- The cigarette case disclosed in
Patent Document 1 can provide the cigarette with moisture; however, the cigarette case cannot deprive the cigarette of moisture. Hence, the humidity of the cigarette might not be maintained at the proper humidity. - The present disclosure is devised to overcome the above problems. The present disclosure is set out to provide: a cigarette packaging material and a cigarette product capable of maintaining humidity of a cigarette at a proper humidity.
- A cigarette packaging material according to an aspect of the present disclosure includes: a packaging material having an inner bottom surface and defining a housing space above the inner bottom surface, the housing space housing a cigarette such that a longitudinal direction of the cigarette is substantially parallel with a depth direction of the housing space; and a humidity control layer housed in the housing space, disposed along the inner bottom surface, and dehumidifying and humidifying the cigarette to control humidity of the cigarette to reach a target humidity.
- A cigarette product according to another aspect of the present disclosure includes: the cigarette packaging material according to the aspect of the present disclosure; and the cigarette.

FIG. 1 is a perspective view schematically illustrating a cigarette product of a first embodiment.FIG. 2 is a cross-sectional view schematically illustrating the cigarette product of the first embodiment. - As illustrated in
FIGS. 1 and 2 , acigarette product 1 of the first embodiment includes: acigarette packaging material 11; and acigarette 12. - The
cigarette packaging material 11 packs thecigarette 12. Thecigarette 12 packaged in thecigarette packaging material 11 may be onecigarette 12 or a plurality ofcigarettes 12. Thecigarette packaging material 11 can control humidity of the packagedcigarette 12 to set to a target humidity. The target humidity is within a range of a relative humidity of 60% RH or more and 80% RH or less. The target humidity is, for example, 70% RH. - The
cigarette 12 is tobacco rolled into a narrow paper cylinder. - As illustrated in
FIGS. 1 and 2 , thecigarette packaging material 11 includes: apackaging material 21; and ahumidity control layer 22. - The
packaging material 21 integrally packages thecigarette 12 and thehumidity control layer 22. Thepackaging material 21 may be either a box having relatively high rigidity, or a soft pack having relatively low rigidity. - As illustrated in
FIG. 2 , thepackaging material 21 has: aninner bottom surface 21A; aninner top surface 21B; and aninner side surface 21C. Thepackaging material 21 defines ahousing space 21S. - The
housing space 21S is surrounded with theinner bottom surface 21A, theinner top surface 21B, and theinner side surface 21C. Thehousing space 21S is defined above theinner bottom surface 21A, and below theinner top surface 21B. Theinner bottom surface 21A and theinner top surface 21B are provided across from one another at thehousing space 21S. - The
housing space 21S houses thecigarette 12 such that a longitudinal direction of thecigarette 12 is substantially parallel with a depth direction of thehousing space 21S. The depth direction of thehousing space 21S is: perpendicular to theinner bottom surface 21A and theinner top surface 21B; and substantially parallel with theinner side surface 21C. The depth direction of thehousing space 21S is a direction from theinner top surface 21B toward theinner bottom surface 21A. - As illustrated in
FIG. 2 , each of thecigarettes 12 includes: a suckedportion 31; and a burningportion 32. - The sucked
portion 31 is located at one end of eachcigarette 12. Theburning portion 32 is located at another end of eachcigarette 12. The suckedportion 31 is sucked at one end of eachcigarette 12. The burningportion 32 burns when eachcigarette 12 is smoked. Eachcigarette 12 is disposed between theinner bottom surface 21A and the innertop surface 21B. The suckedportion 31 is disposed toward the innertop surface 21B. The burningportion 32 is disposed toward theinner bottom surface 21A. - As an example of the cigarette packaging material,
FIGS. 1 and 2 illustrate that thepackaging material 21 includes: amain body 41; and alid 42. The cigarette packaging material may either omit thelid 42 and have an opening in the main body, or include a mechanism with which the main body is partially torn so that thecigarette 12 is taken out. - As illustrated in
FIG. 2 , themain body 41 includes: amain body space 41S; and amain body opening 41P. Thelid 42 includes: alid space 42S; and alid opening 42P. - The
main body space 41S is exposed outside of themain body 41 through themain body opening 41P. Thelid space 42S is exposed outside of thelid 42 through thelid opening 42P. - The
lid 42 can be in a state in which themain body opening 41P is closed, and in a state in which themain body opening 41P is open. When thelid 42 is closed and themain body opening 41P is covered, themain body space 41S and thelid space 42S integrally define thehousing space 21S. When thelid 42 is open and themain body opening 41P is uncovered, themain body space 41S is exposed outside of thepackaging material 21 through themain body opening 41P. Hence, each of thecigarettes 12 can be taken out of themain body space 41S through themain body opening 41P. - The
humidity control layer 22 is housed in thehousing space 21S. Hence, thecigarette 12 and thehumidity control layer 22 are housed together in thehousing space 21S. Such a feature allows moisture to transfer either from thecigarette 12 to thehumidity control layer 22, or from thehumidity control layer 22 to thecigarette 12. - The
humidity control layer 22 dehumidifies and humidifies thecigarette 12 to control the humidity of thecigarette 12 to reach a target humidity. - The humidity control layer 22: absorbs moisture and dehumidifies the
cigarette 12 as indicated by anarrow 51 if the humidity of thecigarette 12 is higher than the target humidity; and releases moisture and humidifies thecigarette 12 as indicated by anarrow 52 if the humidity of thecigarette 12 is lower than the target humidity. Such a feature can keep the tobacco leaf from drying and reduce the risk that the humidity of the tobacco leaf falls below an appropriate humidity. As a result, the tobacco leaf can be kept from burning at high temperature. Consequently, thecigarette 12 will not taste bad for the smoker. Furthermore, the feature can keep the tobacco leaf from getting wet, and reduce the risk that the tobacco leaf might be difficult to burn. Moreover, the feature can keep the tobacco leaf from getting wet, and reduce the risk that mold might grow on the tobacco leaf. - If a desiccant is housed in the
housing space 21S, thecigarette 12 can be dehumidified, but cannot be humidified. If a water-absorbing sponge is housed in thehousing space 21S, thecigarette 12 can be humidified, but cannot be dehumidified. If materials to be housed in thehousing space 21S are switched between a desiccant and a water-absorbing sponge, thecigarette 12 can be dehumidified and humidified. However, the smoker has to switch the materials. In contrast, if thehumidity control layer 22 is housed in thehousing space 21S, thecigarette 12 can be both dehumidified and humidified without switching the materials. - The
humidity control layer 22 is disposed along theinner bottom surface 21A. Thehumidity control layer 22 is placed on theinner bottom surface 21A. Such a feature can keep each of thecigarettes 12 from interfering thehumidity control layer 22 when thecigarette 12 is taken out of themain body space 41S. - The
humidity control layer 22 is in direct contact with thecigarette 12. Such a feature can effectively control the humidity of thecigarette 12 to reach the target humidity. If water vapor can be exchanged between thehumidity control layer 22 and thecigarette 12, thehumidity control layer 22 and thecigarette 12 do not have to be in direct contact with each other, and may be spaced apart from each other. This is because the humidity can be controlled to reach the target humidity if water vapor is permeable between thehumidity control layer 22 and thecigarette 12 through a moisture-permeable material. Because the burningportion 32 of eachcigarette 12 is disposed toward theinner bottom surface 21A, thehumidity control layer 22 disposed along theinner bottom surface 21A comes into direct contact with the burning portion of eachcigarette 12. As the humidity rises, the density of the air decreases. Hence, the higher the humidity of the air is, the more likely the air moves upwards. Thus, thehumidity control layer 22 is disposed along theinner bottom surface 21A, and the burningportion 32 is disposed toward theinner bottom surface 21A. When thecigarette 12 is humidified, the air highly humid and discharged from the humidity control layer readily permeates into the cigarette through the burning portion. As a result, the tobacco leaf readily reaches the target humidity. - If a water-absorbing sponge is housed in the
housing space 21S, the water-absorbing sponge cannot be brought into direct contact with thecigarette 12. This is because when the water-absorbing sponge is brought into direct contact with thecigarette 12, the water-absorbing sponge wets thecigarette 12 with liquid water. Whereas, if thehumidity control layer 22 is housed in thehousing space 21S, thehumidity control layer 22 can be brought into direct contact with thecigarette 12. This is because even if thehumidity control layer 22 is brought into direct contact with thecigarette 12, thehumidity control layer 22 does not wet thecigarette 12 with liquid water. - The
humidity control layer 22 is shaped into either a block or a sheet. Thanks to such a feature, thehumidity control layer 22 is disposed readily along theinner bottom surface 21A. -
FIG. 3A is a view schematically illustrating a humidity control layer included in the cigarette product of the first embodiment. - The
humidity control layer 22 is capable of controlling humidity; that is, if the relative humidity of the air around thehumidity control layer 22 is higher than the equilibrium humidity of thehumidity control layer 22, thehumidity control layer 22 absorbs moisture from the air around thehumidity control layer 22, and if the relative humidity of the air around thehumidity control layer 22 is lower than the equilibrium humidity of thehumidity control layer 22, thehumidity control layer 22 releases the moisture into the air around thehumidity control layer 22. Compared with a desiccant represented by the A-type silica gel, thehumidity control layer 22 can desorb moisture when heated at relatively low temperature. Furthermore, thehumidity control layer 22 can repeatedly absorb and release moisture. Hence, in principle, thehumidity control layer 22 can maintain humidity control capabilities on a semipermanent basis. The equilibrium humidity of thehumidity control layer 22 can be controlled with a material contained in thehumidity control layer 22. - As illustrated in
FIG. 3A , thehumidity control layer 22 includes: aresin material 101; and ahumidity control liquid 102. - The
humidity control layer 22 is shaped into either a block or a sheet. Theresin material 101 of thehumidity control layer 22 is made of aresin 121. Because thehumidity control layer 22 is shaped into either a block or a sheet, water does not seep out from the humidity control layer under the weight of the cigarette itself. Hence, the cigarette does not get wet with liquid water. - The
resin 121 may be either an ionic resin or a non-ionic resin. - The ionic resin contains at least one selected from the group consisting of, for example, alkali metal salt of polyacrylic acid and starch-acrylate graft polymer. The alkali metal salt of polyacrylic acid contains, for example, sodium polyacrylate.
- The non-ionic resin contains at least one selected from the group consisting of, for example, a vinyl acetate copolymer, a maleic anhydride copolymer, polyvinyl alcohol, and polyalkylene oxide.
- The
resin material 101 may contain a clay mineral. - The clay mineral contains at least one selected from the group consisting of, for example, silicate mineral and zeolite. The silicate mineral contains at least one selected from the group consisting of, for example, sepiolite, attapulgite, kaolinite, perlite, dolomite, glassy tuff, and these minerals calcined to form a foam article.
- The humidity control liquid 102 absorbs or releases moisture. The humidity control liquid 102 impregnates the
resin 121. Such a feature makes it possible to increase an area of an interface between the humidity control component and the air, compared with a case where the humidity control liquid is used alone. Hence, the humidity can be controlled quickly. - The humidity control liquid 102 contains at least one selected from the group consisting of, for example, polyhydric alcohol and metal salt.
- The polyhydric alcohol contains at least one selected from the group consisting of, for example, glycerin, propanediol, butanediol, pentanediol, trimethylolpropane, butanetriol, ethylene glycol, diethylene glycol, triethylene glycol, and lactic acid. The polyhydric alcohol desirably contains a polyhydric alcohol having three or more hydroxyl groups. The polyhydric alcohol having three or more hydroxyl groups contains, for example, glycerin. The polyhydric alcohol may constitute a dimer or a polymer.
- The metal salt contains at least one of, for example, lithium chloride, sodium formate, potassium formate, sodium acetate, potassium acetate, sodium lactate, potassium lactate, sodium benzoate, potassium benzoate, sodium propionate, and potassium propionate. The metal salt contained in the
humidity control liquid 102 is desirably hygroscopic. If thehumidity control liquid 102 contains a hygroscopic metal salt, thehumidity control liquid 102 can exhibit high water absorptivity. - The metal salt may be more preferably carboxylic acid salt. Examples of the carboxylic acid salt include sodium formate, potassium formate, sodium acetate, potassium acetate, sodium lactate, potassium lactate, sodium benzoate, potassium benzoate, sodium propionate, and potassium propionate.
FIG. 3B is a graph showing moisture absorption isotherms of sodium formate as an example of carboxylic acid salt and glycerin as an example of polyhydric alcohol. In the graph shown inFIG. 3B , the horizontal axis represents relative humidity, and the vertical axis represents a moisture absorption rate. Note that the moisture absorption rate is expressed as a percentage of the amount of absorbed moisture observed when the relative humidity is varied with reference to the own weight in an absolute dry state at 25° C. When the humidity is controlled within a target humidity range of 60% RH to 80% RH, sodium formate is greater in corresponding moisture absorptivity range than glycerin. This shows that, with respect to glycerin, sodium formate exhibits a small variation in controlled humidity caused when the same amount of moisture is absorbed or released. Hence, sodium formate is more capable of controlling humidity within the target humidity range than glycerin when moisture enters from the outside. For the use of the present invention, carboxylic acid salt such as sodium formate is more preferable. - The humidity control liquid 102 may include a component other than the polyhydric alcohol and the metal salt. For example, the
humidity control liquid 102 may include at least one selected from the group consisting of ketone, an organic solvent having an amide group, a saccharide, and a substance to be used as a raw material for a moisturizing cosmetic product. The organic solvent having an amide group contains at least one selected from the group consisting of, for example, formamide and acetamide. The saccharide contains at least one selected from the group consisting of, for example, sucrose, pullulan, glucose, xylose, fructose, mannitol, and sorbitol. The substance to be used as a raw material for a moisturizing cosmetic product contains at least one selected from the group consisting of, for example, 2-methacryloyloxyethyl phosphorylcholine (MPC), betaine, hyaluronic acid, and collagen. -
FIGS. 4A, 4B, and 4C are views schematically illustrating a method for producing the humidity control layer included in the cigarette product of the first embodiment. - In producing the
humidity control layer 22, as illustrated inFIG. 4A , theresin material 101 is prepared. - Then, as illustrated
FIG. 4B , ahumidity control liquid 111 is prepared. Furthermore, theprepared resin material 101 is immersed in the preparedhumidity control liquid 111. Theresin material 101 is continuously immersed in thehumidity control liquid 111 for, for example, several hours to one day. Thus, thehumidity control liquid 111 permeates into theresin material 101, and thehumidity control layer 22 is formed. The permeatinghumidity control liquid 111 serves as thehumidity control liquid 102 included in thehumidity control layer 22. - Then, as illustrated in
FIG. 4C , the formedhumidity control layer 22 is taken out of the remaininghumidity control liquid 111. The takenhumidity control layer 22 swells by, for example, 2 to 20 times. -
FIG. 5 is a cross-sectional view schematically illustrating a first other example of the resin material included in the cigarette product of the first embodiment. - The
resin material 101 illustrated inFIG. 5 includes: theresin 121; and acarrier 122. In theresin material 101 illustrated inFIG. 5 , theresin 121 is powdery or particulate. Furthermore, thecarrier 122 is a porous solid. The porous solid is a foam article. Furthermore, thecarrier 122 carries theresin 121. When the porous solid constituting thecarrier 122 is a foam article, thecarrier 122 has high rigidity. Thus, thehumidity control layer 22 is stable in shape. Thecarrier 122 may be impregnated with thehumidity control liquid 102. - The
resin material 101 is powdery or particulate. When theresin material 101 is powdery or particulate, the surface area of theresin material 101 is large. This is highly effective in quickly absorbing or removing moisture. -
FIG. 6 is a cross-sectional view schematically illustrating a second other example of the resin material included in the cigarette product of the first embodiment. - The
resin material 101 illustrated inFIG. 6 includes: theresin 121; and thecarrier 122. In theresin material 101 illustrated inFIG. 6 , theresin 121 is either powdery or particulate. Furthermore, thecarrier 122 is a porous solid. The porous solid is either a nonwoven fabric or a woven fabric. Furthermore, thecarrier 122 carries theresin 121. When the porous solid constituting thecarrier 122 is either a nonwoven fabric or a woven fabric, thecarrier 122 is flexible. Hence, thecarrier 122 can alter in shape. Thecarrier 122 may be impregnated with thehumidity control liquid 102. Furthermore, when the porous solid constituting thecarrier 122 is either a nonwoven fabric or a woven fabric, the tobacco leaf falling from thecigarette 12 can be caught by the porous solid. Such a feature can keep tobacco leaf, falling from thecigarette 12, from coming out of thecigarette packaging material 11. -
FIG. 7 is a cross-sectional view schematically illustrating a third other example of the resin material included in the cigarette product of the first embodiment. - The
resin material 101 illustrated inFIG. 7 includes: theresin 121; and thecarrier 122. In theresin material 101 illustrated inFIG. 7 , theresin 121 is either powdery or particulate. Furthermore, thecarrier 122 is a ventilating member that allows an air flow to run in a direction perpendicular to the cross-section illustrated inFIG. 7 . One end of a cigarette comes into direct contact in a direction perpendicular to the cross-section illustrated inFIG. 7 . The ventilating member includes, for example, a corrugated nonwoven fabric. Furthermore, thecarrier 122 carries theresin 121. Thecarrier 122 may be impregnated with thehumidity control liquid 102. - The present disclosure shall not be limited to the above-described embodiment, and may be replaced with a configuration substantially the same as, a configuration having the same advantageous effects as, or a configuration capable of achieving the same object as, the configurations described in the above-described embodiment.
