Patent Document 1: Japanese Patent Laid-Open No. Hei 2-238874

However, the fire extinguisher attached to the cigarette with the filter has the following requirements. First, for example, to suppress fire extinguishers before smoking or smoking Unexpected movement, the fire extinguisher must be securely attached to the filter. Second, the fire extinguisher must be easily separated from the filter and the fire extinguisher can be safely slid to the fire side. Here, in Patent Document 1, it is described that an adhesive may be attached to one point of the short cylinder and temporarily fixed to any position of the paper tobacco. At this time, the smoker must stretch the short tube body with the adhesive followed by the long side direction (axial direction) of the paper roll toward the fire side (front end side), and separate the short cylinder from the paper roll tobacco. At this time, if the smoker separates the short cylinder from the paper roll by one-handed stretching, the short cylinder moves toward the burning side of the fire, and the hand touches the fire.

The present invention has been made in view of the above circumstances, and its object In order to provide a cigarette with a filter, the fire extinguisher is fixed before smoking and during smoking, and at the end of smoking, the smoker can easily and safely slide the fire extinguisher to the fire part of the tobacco rod with one hand.

In order to solve the above problems, the present invention fixes a fire extinguishing cylinder formed of a flame-retardant material into a cylindrical shape by a paste applied to a surface of a destructible capsule or a rupturable capsule, and the fire extinguisher is filtered. When the mouth is separated, the paste is dissolved by breaking the dissolution liquid released by the subsequent paste or the destructible capsule disposed in the vicinity thereof.

More specifically, the filter-attached cigarette of the present invention has a tobacco rod that is wrapped with a shredded tobacco, a filter attached to one end of the tobacco rod, and is formed into a cylindrical shape by a flame-retardant material and fixed to the filter. a fire extinguishing cylinder of a peripheral surface of the nozzle; and a fixing portion disposed between the outer circumferential surface of the filter and the inner circumferential surface of the fire extinguishing cylinder and fixing the fire extinguishing cylinder to the filter; The fixing portion includes a destructible capsule, a paste which is applied to the surface of the easily destructible capsule or the vicinity of the easily destructible capsule, and a solution which is enclosed in the easily destructible capsule and dissolves the paste.

According to the above-mentioned cigarette with a filter, before smoking In the case of smoking, the fire extinguisher is fixed to the filter through the paste of the fixing portion, so that the fire extinguisher can be prevented from unintentionally moving. Then, since the easily destructible capsule of the fixing portion is easily destructible, the destructible capsule can be easily crushed by one hand by the crushing operation at the end of smoking. Next, when the destructible capsule is destroyed, the solution is released from the inside of the easily destructible capsule, and the solution is dissolved by the solution. Thus, the fire extinguisher is separated from the filter by dissolving the paste, and the fire extinguishing cylinder is allowed to slide on the tobacco rod. As a result, the smoker can slide the fire extinguisher toward the fire side.

According to the above composition, the smoker does not need to turn the fire extinguisher toward the incense The smoke is laterally stretched and can be separated from the filter. Therefore, when the fire extinguisher is separated from the filter, the fire extinguisher can be prevented from moving too strongly toward the fire side. Thereby, it is possible to suppress the situation in which the hand comes into contact with the fire when the fire extinguisher is separated from the filter. As a result, the smoker can easily and safely slide the fire extinguisher to the portion of the fire at the end of the tobacco rod with one hand.

From the above, the cigarette according to the present invention, before smoking and The fixing of the fire extinguisher is ensured during smoking, and at the end of smoking, the smoker can easily and safely slide the fire extinguisher to the fire part of the tobacco rod with one hand.

Further, the solution may contain a fragrance. By This configuration suppresses the odor of cigarette butts. Then, since the dissolved solution enclosed in the destructible capsule contains the fragrance, the smoker performs the fire extinguisher in addition to In addition to the action of separating the filter, it is not necessary to force the action of releasing the fragrance to the outside, and the odor of the cigarette butt can be suppressed.

Further, the fire extinguishing cylinder has a two-layer structure including the foregoing The inner layer of the fixing portion, which is followed by the paste, and the outer layer of the inner layer, the inner layer may be formed of a liquid penetrating material, and the outer layer may be formed of a liquid non-penetrating material. Thereby, the solution containing the fragrance released from the easily destructible capsule penetrates into the inner layer which is a liquid penetrating material, and on the other hand, the solution does not penetrate the outer layer formed of the liquid non-penetrating material. As a result, it is possible to suppress the case where the solution containing the fragrance oozes out to the outer peripheral side of the fire extinguishing cylinder. Thereby, it is possible to suppress the smell of the perfume attached to the finger of the fire extinguisher by the smoker during the crushing operation. Conversely, the liquid-permeable material can form the aforementioned outer layer. Thereby, the smoker's finger can be attached to the smell of the fragrance to impart a fragrance to the finger.

Further, the above configuration is formed by a liquid penetrating material The inner layer of the fire extinguisher can slide the fire extinguisher to the fire side in the state where the inner layer of the fire extinguisher is impregnated with the fragrance, so that the smell of cigarette butts on the fire side of the fire extinguishing and the fire extinguishing can be effectively suppressed. Further, since the fragrance is enclosed in the destructible capsule in the form of a solution, the aroma component of the fragrance can be prevented from scattering to the outside until the destructible capsule is destroyed. Moreover, since the smoker destroys the easily destructible capsule, the fragrance is released, so that the fragrance can be inhibited from affecting the flavor during smoking.

Moreover, the package of the filter material contained in the filter is wrapped Paper, and a layer paper disposed on the outer peripheral side of the aforementioned wrapper and wrapping the filter with the tobacco rod, at least a portion of each of which is formed of a liquid permeable liquid penetrating material. By doing so, smoking When the destructurable capsule is destroyed at the end, the solution containing the fragrance released from the easily destructible capsule can be allowed to permeate into the filter through the outer layer paper and the portion of the wrapping paper formed of the liquid penetrating material. Thereby, the cigarette odor generated from the filter side can be effectively suppressed.

Moreover, the fire extinguishing cylinder is transmitted through a plurality of the aforementioned fixing portions Then, on the outer peripheral surface of the filter, the plurality of fixing portions may be arranged along the circumferential direction of the fire extinguishing cylinder. Thereby, the fragile capsule of the plurality of fixing portions can be simultaneously destroyed by one crushing operation.

Moreover, the fire extinguishing cylinder is connected through the two fixing portions The fixing portions may be disposed on the outer peripheral surface of the filter, and the fixing portions may be disposed at two places facing each other in the circumferential direction of the fire extinguisher. According to this configuration, it is possible to suppress the unintended movement of the fire extinguisher before smoking and during smoking, so that the degree of fixation of the fire extinguisher to the filter can be sufficiently ensured. Moreover, the destructible capsules in all the fixing portions can be simultaneously destroyed by one crushing operation of the smoker, so that the fire extinguishing using the fire extinguishing cylinder is made easier. This can improve the usability of the fire extinguisher.

Moreover, a mark may be attached to the outer surface of the fire extinguisher Note that the mark indicates the position of the fixing portion disposed on the inner circumferential side of the fire extinguisher. According to this configuration, the smoker can easily and surely grasp the position of the fixed portion (destructible capsule). Thereby, the smoker can correctly crush the capsule of the fixed portion at the end of smoking, and the operability of the fire extinguisher can be further improved.

Further, the means for solving the problems in the present invention can be combined and used within a feasible range.

According to the present invention, a cigarette with a filter can be provided. The fixing of the fire extinguisher is ensured before smoking and during smoking, and at the end of smoking, the smoker can easily and safely slide the fire extinguisher to the fire part of the tobacco rod with one hand.

<Embodiment 1> <Cartridge with filter>

Fig. 1 is an external view of a filter cigarette (hereinafter simply referred to as "cigarette") 1 according to the embodiment. The cigarette 1 has a tobacco rod 2, a filter 4 connected to one end of the tobacco rod 2 through a tipping paper 3, and a fire extinguisher 5 belonging to a tubular fire extinguisher for extinguishing the cigarette 1. The tobacco rod 2 is a so-called "single roll" in which the shredded tobacco 21 is wrapped in a roll paper 22 and formed into a cylindrical shape (rod shape). The broken line in Fig. 1 indicates the position of the boundary between the tobacco rod 2 and the filter 4 in the cigarette 1.

Fig. 2 is a schematic view showing a longitudinal section of the cigarette 1 of the first embodiment. Fig. 3 is a cross-sectional view taken along the arrow A-A of Fig. 2. The filter 4 is a member for filtering the smoke component contained in the mainstream smoke when the mainstream smoke generated by smoking the cigarette 1 passes, and includes a filter material 4 formed into a cylindrical shape, and a package wrapped around the filter medium 41. Paper 42. As the filter medium 41, a known filter material for cigarettes can be suitably used, and for example, a fiber bundle of cellulose acetate formed into a cylindrical shape can be used.

The filter 4 including the filter medium 41 and the wrapped paper 42 is wound around the entire outer layer paper 3, and is connected to one end side of the tobacco rod 2 through the outer layer paper 3. The outer layer paper 3 integrally wraps the end portion of the tobacco rod 2 with the filter 4 as a whole, thereby connecting the same. Therefore, the outer layer paper 3 forms the outer peripheral surface of the filter 4. Hereinafter, in the longitudinal direction (axial direction) of the tobacco rod 2, the end portion on the side to which the filter 4 is connected is referred to as a "rear end", and the end portion on the opposite side is referred to as a "front end" (tip end). Further, when the cigarette 1 is smoked, the "hot spot" is formed by the burning of the tobacco rod 2 on the front end side. Further, in the longitudinal direction (axial direction) of the filter 4, the end portion on the side to which the tobacco rod 2 is connected is referred to as a "front end". The end on the opposite side is called the "sucking end".

<extinguish tube>

The cigarette 1 has a fire extinguisher 5 which is used for a fire extinguisher in which the smoker does not have to perform the action of pressing out the cigarette 1 at the end of smoking. The fire extinguisher 5 is formed into a cylindrical shape by a flame-retardant material, and is fixed to the outer peripheral surface of the filter 4 in a state of being inserted into the filter 4. In the present embodiment, the fire extinguisher 5 is made of flame retardant paper. Here, the term "flame retardant material" also includes a non-combustible material, and "flame-retardant paper" may also contain non-combustible paper. Further, in the present embodiment, the fire extinguisher 5 is formed of a flame-retardant paper, but it may be formed of a metal foil or the like. Further, the length of the fire extinguisher 5 (the dimension along the axial direction) is not particularly limited, and the lengths of the filter 4 are shorter in the examples shown in Figs. 1, 2, and 2. Next, the fire extinguisher cylinder 5 is attached so as to expose the suction port end side of the filter 4 and cover the outer periphery of the front end side of the filter 4.

At the end of smoking, the smoker performs an operation of separating the fire extinguisher 5 from the filter 4 and sliding the fire extinguisher 5 to the fire portion located on the front end side of the tobacco rod 2. The inner circumference of the fire extinguisher 5 is set to a size slightly larger than the length of the outer periphery of the filter 4 and the tobacco rod 2. Thereby, when the smoker finishes, the smoker separates the fire extinguisher 5 from the filter 4, and the fire extinguisher 5 can be smoothly and easily slid to the position of the fire formed on the front end side of the tobacco rod 2. In addition, as will be described in detail later, if the smoker slides the fire extinguisher 5 to the fire position of the tobacco rod 2 at the end of smoking, the fire is surrounded by the fire-retardant fire extinguisher 5, and the cigarette 1 can be automatically extinguished. Or it can assist the fire extinguishing of cigarette 1.

Here, the symbol 51 in the figure indicates the inner circumference of the fire extinguisher 5 The surface 52 indicates the outer circumferential surface of the fire extinguisher 5. A fixing portion 6 is interposed between the outer layer paper 3 of the package filter 4 and the inner circumferential surface 51 of the fire extinguishing cylinder 5, and the fire extinguishing cylinder 5 is fixed to the outer layer paper 3 of the package filter 4 by the fixing portion 6 ( The outer surface of the filter 4). Fig. 4 is a view showing the detailed structure of the fixing portion 6 of the first embodiment. The fixing portion 6 includes a destructible capsule 61 which is easily destructible, a paste 6 applied to the surface of the destructible capsule 61, and a solution which is accommodated (sealed) inside the destructible capsule 61 and used to dissolve the paste 62. 63.

In the present embodiment, the easily destructible capsule 61 is formed into In the shape of a ball, the entire spherical surface is covered with the paste 62. However, the subsequent paste 62 in the fixing portion 6 may be applied so as to cover a part of the surface of the destructible capsule 61. Examples of the material which imparts destructibility to the destructible capsule 61 include gelatin or pullulan. By using these to produce the destructible capsule 61, the easily destructible capsule 61 which can be easily broken (crushed) when the smoker presses can be obtained.

Here, the interior of the easily destructible capsule 61 is sealed and dissolved. The solution 63 of the paste 62 is then dissolved. As will be described later in detail, when the smoker performs the crushing operation of crushing the capsule 61 at the end of smoking, the solution 63 in which the destructible capsule 61 is sealed releases and dissolves the paste 62, thereby releasing the fire extinguisher 5 for the package. The subsequent state of the paper 3 outside the filter 4. Next, the paste 62 is preferably, for example, a starch-based adhesive, a urethane resin-based adhesive, a polyvinyl alcohol-based adhesive, an acrylic resin-based adhesive, a CMC (carboxymethylcellulose) paste, or a polyvinylpyrrolidone paste. Wait. However, the type of the paste 62 formed on the surface of the easily destructible capsule 61 is not limited to the above exemplification. Further, the solution 63 enclosed in the interior of the destructible capsule 61 is, for example, water, Glycerin, propylene glycol, aqueous ethanol solution, ethanol, vinegar, acetone, vegetable oil, olive oil, medium chain triglyceride (MCT), etc., but are not limited to these examples.

Next, the arrangement state of the fixing portion 6 in the present embodiment will be described. kind. In the example shown in Fig. 3, two (a pair of) fixing portions 6 are disposed between the outer layer paper 3 and the fire extinguishing cylinder of the package filter 4. More specifically, the fixing portions 6 are respectively disposed at two places facing each other in the circumferential direction of the fire extinguisher 5 (filter 4). In other words, the pair of fixing portions 6 are disposed at positions deviated by about 180 degrees in the circumferential direction of the fire extinguisher 5 (filter 4). However, the configuration of the fixing portion 6 is not limited to the above configuration example.

Moreover, the symbols 7 shown in FIGS. 1 to 3 are formed in The mark of the outer peripheral surface 52 of the fire extinguisher 5. Reference numeral 7 denotes a position of the fixing portion 6 (destructible capsule 61) disposed on the inner circumferential surface 51 side of the fire extinguisher 5. In the example shown in Fig. 1, the mark 7 is formed by printing a dot on the outer peripheral surface 52 of the fire extinguisher 5. However, as long as the smoker can discriminate the position of the fixed portion 6, various modifications can be employed. That is, the shape, size, and the like of the mark 7 can be changed to other aspects. Further, the outer peripheral surface 52 can be formed by the so-called uneven processing such as embossing or gravure printing, instead of printing ink on the outer peripheral surface 52 of the fire extinguisher 5, or both.

Reference numeral 7 denotes the outer peripheral surface 52 of the fire extinguisher 5 and the solid The fixed portion 6 is disposed at a position where the upper portion 6 is overlapped with each other, and the fixed portion 6 is interposed between the outer layer paper 3 of the package filter 4 and the fire extinguishing tube 5. As described above, the fixing portions 6 are respectively disposed at two positions facing each other in the circumferential direction of the fire extinguishing cylinder 5 (filter 4) (a position shifted by 180° in the circumferential direction). Therefore, the configuration of the fixing portion 6 is matched. The pair of marks 7 are respectively printed on two places facing each other in the circumferential direction of the fire extinguisher 5 (filter 4) (a position shifted by 180 in the circumferential direction).

According to the cigarette 1 described above, before smoking or during smoking The fire extinguishing cylinder 5 is fixed to the filter 4 through the fixing portion 6 (more specifically, the outer peripheral sheet 3 constituting the outer surface of the filter 4), so that the fire extinguishing cylinder 5 can be prevented from unintentionally moving toward the front end side of the tobacco rod 2.

Further, at the end of the cigarette 1 smoking, the smoker performs a crushing operation of crushing the fire extinguisher 5 from the outside. Here, the destructible capsule 61 disposed in the fixing portion 6 on the inner circumferential surface 51 side of the fire extinguisher 5 is easily destructible. Therefore, the fire extinguisher 5 is lightly pinched by one hand and a moderate force is applied, whereby the easily destructible capsule 61 can be easily crushed. As described above, when the fixing portion 6 is crushed by the crushing operation of the smoker, the dissolved liquid 63 enclosed in the destructible capsule 61 is released to the outside. As a result, the paste 62 coated on the surface of the destructible capsule 61 is dissolved by the solution 63. As a result, the fixed state of the fire extinguisher 5 fixed to the filter 4 is released, and the fire extinguisher 5 is separated from the filter 4. Thereby, the state in which the fire extinguishing cylinder 5 is allowed to slide the tobacco rod 2 is obtained. That is, the state in which the fire extinguisher 5 is slidable relative to the tobacco rod 2 . If the fire extinguisher 5 is slid to the fire part of the tobacco rod 2, the cigarette 1 will automatically extinguish the fire. Therefore, the smoker can extinguish the cigarette 1 without performing the action of pressing the flame of the cigarette 1.

According to cigarette 1, the smoker does not need to turn the fire extinguisher 5 toward the incense The fire side (front end side) in the longitudinal direction (axial direction) of the cigarette 1 is stretched, and the fire extinguisher 5 can be separated from the filter 4 by one hand, and the fire extinguisher 5 can be slid toward the fire side. Thus, that is, when the fire extinguisher 5 is separated from the filter 4, it is not necessary to The fire extinguisher 5 is stretched toward the fire side, so that the fire extinguisher 5 separated from the filter 4 does not move too strongly toward the fire side. Therefore, there is no possibility that the hand is exposed to the fire when the fire extinguisher 5 is separated from the filter 4.

According to the cigarette 1 of the above embodiment, it is smoking The fixing of the fire extinguisher 5 is ensured before and during smoking, and the smoker can easily and safely slide the fire extinguisher 5 to the fire part of the tobacco rod 2 with one hand at the end of smoking. Further, the cigarette 1 overflows the solution 63 from the crushable destructive capsule 61 when the fire extinguisher 5 is separated from the filter 4, so that the fire extinguisher 5 can be imparted with liquid impermeability. When the fire extinguishing cylinder 5 is in the stratified structure, when the liquid is not penetrable in any of the layers, the dissolved liquid 63 does not ooze out to the outer peripheral surface 52 side of the fire extinguishing cylinder 5, and the adhesion of the dissolved liquid 63 to the fingers of the smoker can be suppressed.

Further, the cigarette 1 of the present embodiment is a crushing fixing portion 6 The destructible capsule 61 is dissolved in the paste 62 by the dissolution liquid 63 released from the destructible capsule 61, whereby the fire extinguisher 5 can be easily separated from the filter 4. Therefore, from the viewpoint of improving the ease of separation of the fire extinguishing cylinder 5 fixed to the filter 4, the number of the fixing portions 6 is preferably not too large. For this reason, the number of the fixing portions 6 to which the fire extinguishing cylinder 5 is fixed to the filter 4 can be four or less. Accordingly, the fire extinguisher 5 can be more easily separated from the filter 4 by the crushing operation of the smoker.

Moreover, the fire extinguisher 5 is fixed to the plurality of fixing portions 6 In the case of the filter 4 (the outer layer paper 3 of the package filter 4), as in the present embodiment, a plurality of fixing portions 6 can be arranged along the circumferential direction of the fire extinguishing cylinder 5 (filter 4). Thus, by arranging the plurality of fixing portions 6 in the circumferential direction of the fire extinguishing cylinder 5 (filter 4), the destructibility in the plurality of fixing portions 6 can be performed by one crushing operation. The capsule 61 is simultaneously destroyed.

Moreover, if it is fixed by at least two (two places) fixing portions 6 The fire extinguisher 5 is considered to ensure the degree of fixation of the fire extinguisher 5 required for the unintended sliding (separation from the filter 4) of the fire extinguisher 5 before and during smoking. Here, in the present embodiment, two fixing portions 6 are interposed between the outer layer paper 3 and the fire extinguishing cylinder 5, and the two fixing portions 6 are respectively disposed in the fire extinguishing cylinder 5 (filtering) The position in the circumferential direction of the mouth 4). Thereby, the undesired movement of the fire extinguishing cylinder 5 before and during smoking is suppressed, so that the degree of fixation of the fire extinguishing cylinder 5 with respect to the filter 4 can be sufficiently ensured. Moreover, the destructive capsules 61 of all the fixing portions 6 can be simultaneously destroyed by one crushing operation by the smoker, so that the fire extinguishing using the fire extinguishing cylinder 5 is easier, and the usability of the fire extinguishing cylinder 5 is also improved.

Further, the cigarette 1 of the present embodiment is outside the fire extinguisher 5 The circumferential surface 52 is provided with a mark 7 indicating the position of the fixing portion 6 disposed on the inner circumferential surface 51 side of the fire extinguisher 5, so that the smoker can easily and surely grasp the position of the fixing portion 6. Therefore, at the end of smoking, according to the position of the mark 7, the smoker can grasp at a glance where the fire extinguisher 5 should be pressed to separate the fire extinguisher 5 from the filter 4. Thereby, the smoker can crush the fragile capsule 61 of the fixing portion 6 more accurately at the end of smoking, and the usability of the fire extinguisher 5 can be improved.

Next, the flame-retardant paper forming the fire extinguisher 5 will be described. This embodiment In the state, the evaluation test of the flame retardancy of various samples (hereinafter referred to as "flame retardancy evaluation test") was carried out according to the following method. The flame retardancy evaluation test will be described in detail below.

Fig. 5 is a schematic view of a test apparatus 100 used in a flame retardancy evaluation test. The test apparatus 100 includes a power supply unit 110, a heater 120, a data logger 130, a thermocouple 140, and the like. The specifications of each machine included in the test apparatus 100 are as follows. That is, the power supply unit 110 uses a DC stabilized power supply device (output adjustment: 10A), and the heater 120 uses a resistance heating portion (heating portion) of an electric heating igniter (Bolgwaldt). Further, the data logger 130 has a sampling rate of 1 point per second (1 point / 1 s). Again, the thermocouple 140 uses a k thermocouple ( =0.5mm).

The flame retardancy evaluation test using the above test apparatus 100 was carried out in the following order. The sample (paper) 150 of the test object is brought into contact with the heater 120 and heating is started. After the heating of the heater 120 is started, the heater temperature is measured by the thermocouple 140, and the sample temperature of the sample 150 opposite to the heater is measured. After 30 seconds from the start of heating, the heating of the heater 120 was stopped, and the temperature history of the sample 150 from the start of heating to 120 seconds passed was measured. In the above test, the point at which the sample temperature was higher than the heater temperature was detected, and the time required to start the heating of the sample 150 until the sample temperature exceeded the heater temperature was measured.

Fig. 6 shows the results of the flame retardancy evaluation test conducted with the samples 1 to 4. As shown in Fig. 6, in the test 1 and the sample 3, the sample temperature did not exceed the heater temperature during the test. On the other hand, in the sample 2, the sample temperature exceeded the heater temperature 17 seconds after the start of heating. Further, in the sample 4, the sample temperature exceeded the heater temperature 10 seconds after the start of heating. In the present embodiment, a sample which is required to have a sample temperature of more than the heater temperature after the start of heating of the sample is 18 seconds or longer (including a case where the sample temperature never exceeds the heater temperature) may be defined as a flame-retardant paper. For example, according to the definition, the sixth In the samples 1 to 4 shown in the test results, the sample 1 and the sample 3 which satisfy the condition that the sample temperature exceeds the heater temperature for 18 seconds or more after the start of heating are flame-retardant paper, and it is preferable to use such a flame-retardant paper. Make a fire extinguisher 5. The fire extinguisher 5 having the flame-retardant paper having such a property is disposed in such a manner as to surround the fire of the tobacco rod 2, whereby the fire extinguisher 5 can be easily fired without igniting the fire.

In addition, the flame retardant paper can be made by ordinary cigarettes. It is obtained by performing a process for reducing oxygen penetrating energy by using a paper material (for example, cellulose fiber paper or the like). An example of a processing method for lowering the oxygen permeability of the paper material is a method of drying the film forming material on the surface of the paper material to be processed and drying it. The film forming material may, for example, be a cellulose derivative such as alginic acid and a salt thereof (for example, a sodium salt), pectin, polyvinyl alcohol, ethyl cellulose, methyl cellulose or carboxymethyl cellulose; starch or a derivative (for example, an ether derivative such as carboxymethyl starch, hydroxyalkyl starch or cationic starch, an acetate derivative such as starch acetate, starch phosphate or octenylsuccinic acid starch), but is not limited thereto. Wait. These film forming materials can be generally used as an aqueous solution of 1.0 to 30.0% by weight, and such an aqueous solution can be applied to the surface of the paper material constituting the fire extinguishing cylinder 5 by, for example, a suitable printing method such as gravure printing. Thereafter, the applied film forming material is dried, whereby the oxygen permeability of the paper material can be lowered and the flame retardancy can be imparted as compared with that before the processing.

Next, the coated destructive capsule in the fixing portion 6 will be described. A combination of the surface paste 62 of the surface 61 and the solution 63 enclosed in the interior of the destructible capsule 61. Here, in addition to the combination of the paste and the solution, the evaluation of the ease of dissolution of the solution with the paste is also performed (hereinafter referred to as It is "Solubility Evaluation Test"). The solubility evaluation test will be described in detail below. In the solubility evaluation test, a cigarette 200 with a filter as shown in Fig. 7 is prepared, and a paste portion 203 which is a part of the surface of the layer paper 202 on the outer peripheral surface of the filter 201 is coated with a paste, and the sheet 204 is passed. In the filter 201. The size of the pasted area 203 is 2 mm x 1 mm. Further, the size of the paper sheet 204 is 2 mm × 20 mm, and the material of the paper sheet 204 is the sample 1 described in Fig. 6. Further, the paste of the paper sheet 204 is applied to the entire paste-coated region 203. After the paste was dried, 10 μl of the solution was added between the outer layer paper 202 and the paper sheet 204. Thereafter, the sheet 204 was stretched upward, and the elapsed time required to peel off the sheet 204 was measured, and the evaluation price was evaluated in four stages based on the elapsed time.

Fig. 8 is a view showing the results of a solubility evaluation test. Fig. 8 shows the elapsed time (hereinafter referred to as "peeling time") from the post-stretching of the paper sheet 204 to the peeling in the solubility evaluation test in the combination of each of the paste and the solution. In the test, a starch-based adhesive, a urethane resin-based adhesive, a polyvinyl alcohol-based adhesive, an acrylic resin-based adhesive, a CMC (carboxymethylcellulose) paste, and a poly-polymer can be used in the test.

<Embodiment 2>

Next, the second embodiment will be described. Fig. 9 is a view showing a schematic configuration of a filter 4A of the second embodiment. Here, differences from Embodiment 1 will be mainly described. The filter 4A of the second embodiment contains a fragrance in the solution 63 of the destructible capsule 61 sealed in the fixing portion 6A.

Moreover, the fire extinguisher 5A has a two-layer structure and has a fixed portion. The inner layer 50A followed by the paste 63 of 6A and the outer layer 50B laminated to the inner layer 50A. Next, the inner layer 50A of the fire extinguisher 5A is formed of a liquid penetrating material that penetrates the liquid. Further, the outer layer 50B is formed of a liquid non-penetrating material that does not penetrate the liquid. Further, reference numeral 42A in Fig. 9 is a liquid penetrating portion formed in a portion of the package paper 42 around the filter medium 41 in the filter 4A. Further, the symbol 3A is a liquid penetrating portion formed in a part of the outer layer paper 3. The liquid penetrating portion 42A in the wrapper 42 and the liquid penetrating portion 3A in the outer layer paper 3 are formed of a liquid penetrating material that penetrates the liquid. The liquid penetrating portion 42A of the wrapped paper 42 and the liquid penetrating portion 3A of the outer layer paper 3 are disposed at positions corresponding to the fixed portion 6 in the longitudinal direction of the filter 4, respectively.

In the filter 4A configured as described above, at the end of smoking, The fragile capsule 61 of the fixed portion 6A is broken by the crushing operation of the smoker, and the solution 63 containing the fragrance enclosed therein is released. The dissolution liquid 63 is dissolved in the paste 63 and the fire extinguisher 5A is separated from the filter 4A, whereby the fire extinguisher 5A can be slid to the fire side, which is the same as in the first embodiment.

Furthermore, in the present embodiment, the fire extinguishing cylinder 5A is a two-layer structure. The inner layer 50A is formed of a liquid penetrating material. In this way, contain The solution 63 of the fragrance released from the destructible capsule 61 will infiltrate into the inner layer 50A which is a liquid penetrating material, and on the other hand, the outer layer 50B which is formed by the liquid non-penetrating material will not penetrate the solution. 63. As a result, it is possible to suppress the fragrance-containing solution 63 from oozing out to the outer peripheral surface 52 side of the fire extinguishing cylinder 5A. Thereby, it is possible to suppress the smoke of the smoker's finger from pinching the fire extinguisher 5A at the time of the crushing operation.

Moreover, the fire extinguisher 5A is immersed in the inner layer 50A. In the state of sliding to the side of the fire, it can suppress the smell of cigarette butts on the fire side of the fire extinguishing and after the fire. Further, since the fragrance is enclosed in the destructible capsule 61 in the form of the solution 63, the aroma of the fragrance can be suppressed from being dispersed to the outside until the destructible capsule 61 is destroyed. Then, when the destructible capsule 61 is destroyed at the end of smoking, the fragrance is released, so that the fragrance is inhibited from affecting the flavor during smoking.

Furthermore, the filter 4A of the present embodiment is in the outer layer The liquid penetrating portions 3A and 42A are formed at positions corresponding to the fixing portion 6A of the paper 3 and the wrapping paper 42. Thereby, at the end of smoking, the solution 63 containing the fragrance released from the damaged destructible capsule 61 can be infiltrated through the liquid penetrating portions 3A, 42A in the outer layer paper 3 and the wrapped paper 42. Filter medium 41. Thereby, the cigarette odor generated from the side of the filter 4A can be suppressed.

In this embodiment, it is formed of a liquid penetrating material. The inner layer 50A of the fire extinguishing tube 5A and the liquid penetrating portions 3A and 42A are formed on the outer layer paper 3 and the wrapped paper 42, so that the cigarette odor in both the fire side and the filter side can be reduced. Next, the fire extinguishing cylinder 5A is placed by dissolving the dissolving liquid 63 in the paste 62 for fixing the fixing portion 6A to the filter 4A. In addition to the action of separating from the filter 4A, the smoker does not need to reluctantly perform the action of releasing the fragrance to the outside, and the soot odor of the fire or the filter can be suppressed. However, the above-described configuration on the side of the fire extinguishing cylinder 5A can be used to suppress the odor of the butt on the fire side, and the above-described configuration on the side of the outer paper 3 and the wrapped paper 42 can be used to reduce the odor of the cigarette butt on the filter side.

Moreover, in the example shown in Fig. 9, it is on the outer paper 3 and the roll. A part of the wrapping paper 42 forms the liquid penetrating portions 3A, 42A, but the liquid penetrating portions 3A, 42A can be formed integrally on the outer layer paper 3 and the wrapped paper 42. Further, in the example shown in Fig. 9, the positions of the liquid penetrating portions 3A and 42A in the longitudinal direction of the filter 4A correspond to the positions of the fixed portion 6A, but the present invention is not limited thereto. The solution 63 containing the fragrance released from the destructible capsule 61 can pass through the liquid penetrating portions 3A, 42A and penetrate into the filter medium 41, and the position of the liquid penetrating portions 3A, 42A and the position of the fixing portion 6 can also be used in this range. Deviation. However, by conforming to the positions so as to coincide with each other, the fragrance of the destructible capsule 61 can be more efficiently infiltrated into the filter medium 41, so that the suppressing effect of the cigarette odor of the filter can be further enhanced.

In addition, in the present embodiment, it is sealed in a destructible glue. The type of the fragrance contained in the solution 63 in the capsule 61 is not particularly limited, and various flavors which can be added to a general cigarette can be widely used. Further, the fragrance contained in the solution 63 may be vaporized while destroying the destructible capsule 61, or may be vaporized by the heat of the fire when the fire extinguisher 5A is moved to the fire position. In the latter case, there is the advantage that a lower vapor pressure perfume can be used. Furthermore, in the latter case, the fragrance is released at the position of the fire rather than the position of the filter, so it is difficult for the smoker to feel the smell of the fragrance, and it is also possible to suppress the influence on the fragrance. advantage.
