Description

Cigarettes and packaging materials

This invention relates to the cigarette technology which has a capsule in a filter part.

Conventionally, a cigarette is known in which a capsule containing a liquid containing a fragrance is incorporated in a cigarette filter, and the fragrance of the fragrance is enjoyed by rupturing the capsule during smoking.

The capsule is placed inside the filter for filtering mainstream smoke placed at one end of the cigarette, and the user can destroy the capsule placed inside by applying pressure to the filter with a finger (patent) Reference 1).

JP 2003-304856 A

Thus, as an added value given to the user by the capsule, it was considered to change the taste during the smoking by the fragrance in the capsule, but in recent years a new added value has been demanded.

The present invention has been made in view of these facts, and its main technical problem is to provide a new added value to be given to the user by the capsule, and the user ruptures the capsule as a new added value. The purpose is to provide a cigarette with a capsule that allows you to enjoy the feeling of being broken.

According to the study by the present inventors, the “cracked feeling” by the user is related to the tactile sensation (change in pressure) felt by the part applying pressure to the capsule such as a finger, and the sound that the user feels with hearing. I understood. In other words, there is a correlation between “the sound generated when the capsule is ruptured (hereinafter referred to as“ the volume of bursting ”)” and “the feeling of being broken”. A feeling can be felt.

Note that the bursting volume here is defined as the volume calculated by the measurement method described later.

According to the present invention, there is provided a cigarette rod and a filter having a capsule connected to one end of the cigarette rod and holding the contents in the film, the capsule having a bursting volume of 0.7 to 1.. A cigarette that is 0 Vrms is provided.

The rupture hardness of the capsule may be 25 to 70 N, preferably 25 to 40 N, and the capsule film may contain starch and a gelling agent.

Note that the bursting hardness is the force required to burst the capsule. That is, a capsule having a rupture hardness of 25N means a capsule that ruptures when a pressure of 25N is applied.

Also, the capsule may be a breaking capsule for teeth that is divided by teeth, and the deformation rate is preferably 3/4 or less.

The center position of the capsule for breaking teeth is preferably arranged at a position 9 to 20 mm away from the suction end of the filter, and the filter has a tactile sensation detecting portion that provides a tactile sensation different from other parts on the outer peripheral surface. The tactile sensation detection unit is preferably arranged at the same position as the capsule is arranged in the longitudinal direction of the cigarette. The tactile sensation detection unit can be formed by embossing, or can be formed by outer peripheral paper arranged around the hollow part.

Further, a message display unit may be provided that displays that the tooth breaking capsule is to be broken by a tooth. Furthermore, according to this invention, a packaging member provided with the message display part which displays dividing a dental destruction capsule with a tooth is provided.

According to the present invention, as a new added value, there is provided a cigarette with a capsule that allows the user to enjoy a “breaking feeling” when the capsule is ruptured.

Hereinafter, examples of the embodiments of the present invention will be described, but the present invention is not limited to the specific modes of the embodiments, and is defined by the description of the claims and the equivalents thereof.

<First embodiment>
FIG. 1 shows a cigarette having a capsule filter according to an embodiment of the present invention. The cigarette is a cigarette rod 10 in which a cigarette filling 11 is wound with a wrapping paper 12 and a cylindrical filter 20 in which a filter plug 22 in which a capsule 21 is embedded is wound with a winding paper 23 is connected by a chip paper 30. is there. The capsule 21 has a structure in which a content liquid 21b containing a fragrance, which is an example of the content, is wrapped with a film 21a (in this specification, a filter having a structure in which a capsule is embedded in a filter plug is referred to as an “embedded filter” in this specification). Called).

For example, the filter plug has a single yarn fineness of 1.0 to 14.0 g / 9000 m (preferably 5.0 to 14.0 g / 9000 m, more preferably 5.0 to 1 g) extending in a direction substantially parallel to the longitudinal direction of the cigarette. 6.0 g / 9000 m) of cellulose acetate fibers are collected, and as a plasticizer for the filter, for example, triacetin is added to the fiber weight ratio plasticizer addition amount 2 to 10% (preferably 3 to 6%), and the total fineness 17000 to Those prepared under the conditions of 44000 g / 9000 m (preferably 17000 to 35000 g / 9000 m) and ventilation resistance of 100 to 700 mmH ₂ O / 120 mm (preferably 260 to 680 mmH ₂ O / 120 mm) can be used. It is also possible to use a bundle of paper mainly made from plant pulp and having a basis weight of 15 to 60 g / m ² , a thickness of 20 to 150 μmm, and a width of 14 mm to 27 mm. The filter plug may contain activated carbon.

As the chip paper 30, paper made of vegetable pulp and having a basis weight of 20 to 60 g / m ² and a thickness of 20 to 60 μm can be used. As the winding paper 23, paper made of vegetable pulp and having a basis weight of 20 to 100 g / m ² , a thickness of 20 to 150 μmm, and an air permeability of 5 to 30000 CU can be used.

For example, the cigarette has a tobacco rod length (a in the figure) of 53 to 67 mm, a filter length (b in the figure) of 17 to 31 mm, an outer peripheral length of the chip paper of 14 to 26.1 mm, and the cigarette longitudinal direction of the capsule The size can be 1 to 8 mm.

<Capsule>
The capsule 21 has a structure in which a content liquid 21b containing a fragrance, which is an example of the content, is wrapped with a film 21a. As the capsule, a sphere or a cylinder can be used.

The film-forming material contains, for example, starch and a gelling agent. For example, gellan gum or gelatin is used as the gelling agent. The film forming material may further contain a gelling aid. For example, calcium chloride is used as the gelling aid. In the present invention, the film forming material may further contain a plasticizer. Glycerin and / or sorbitol is used as the plasticizer. The film-forming material may further contain a colorant.

Also, the capsule may contain the contents of the individual such as granules.

As the fragrance contained in the capsule content liquid, for example, menthol, plant essential oil, and the like can be used. As a fragrance solvent contained in the content liquid, for example, medium chain fatty acid triglyceride (MCT) can be used. The content liquid may further contain other additives such as a pigment, an emulsifier, and a thickener.

The capsule 21 in this embodiment has a burst volume of 0.7 to 1.0 Vrms (the user may feel uncomfortable when the burst volume exceeds 1.0 Vrms), and has a burst hardness of 25 to 70 N, preferably 25 to 40 N (if the bursting hardness is too high, it may be difficult for the user to break the capsule), and the deformation rate is 3/4 or less. In this way, since the bursting volume of the capsule is 0.7 Vrms or more, the user can enjoy the “breaking feeling” due to the bursting sound. When the capsule is spherical, it is preferable that the diameter is 4.0 to 6.0 mm since the user can fully feel the presence of the capsule because the “breaking feeling” is improved.

<Deformation rate>
Note that the bursting hardness and deformation rate of the capsule can be adjusted by changing the composition and thickness of the film forming material, and the deformation rate is a filter when the filter plug is not subjected to external pressure as shown in FIG. Defined as (C−D) / C, where C is the distance of the portion e where the plug 212a is pushed and D is the distance of the portion e ′ where the filter plug 212b is pushed when the filter plug is subjected to external pressure. Is done.

<Action that enhances the feeling of cracking>
In the present embodiment, the capsule burst hardness is increased as one method for increasing the burst volume. Here, if the bursting hardness is increased in order to increase the bursting volume, it may be difficult to break the capsule with a finger as in the conventional case. In such a case, the bursting sound volume can be increased by making the capsule into a tooth breaking capsule for the user to divide by the teeth, and the user can be given a great “feeling of cracking”.

Further, by setting the deformation rate to 3/4 or less, the pressure applied to the capsule by the user is increased in a shorter time (in other words, the total amount of applied pressure applied to the capsule by the user is further reduced). ) By releasing the repulsive force from the capsule at the same time as the capsule is destroyed, a greater tactile sensation (change in pressure) can be given to the user.

Furthermore, in the case of this embodiment, since the bursting hardness of the capsule is large, the magnitude of the repulsive force released is also larger than that of the conventional capsule, and a greater tactile sensation (change in pressure) can be given to the user.

In this way, it is possible to give the user a greater “feeling of cracking” by simultaneously giving a bursting sound volume and a large tactile sensation (change in pressure).

<Capsule production method>
The method for producing the fragrance capsule is not particularly limited, but for example, the dropping method is preferable because the fragrance capsule having a seamless film can be produced. In this method, by using a double nozzle and simultaneously discharging the content liquid from the inner nozzle and the liquid film substance from the outer nozzle, the film liquid can wrap the content liquid seamlessly. For example, a capsule having a high bursting hardness can be produced by increasing the thickness of the coating 21a during production.

<Destruction capsule for teeth>
If the capsule is a dental breaker capsule, the user can feel the vibration caused by breaking the capsule directly through the skull with the auditory nerve by dividing the capsule with the teeth, which is greater than when the capsule is crushed with a finger. Can be obtained.

Also, even if such bone conduction sound is full of sounds around the user, it is not hindered by these sounds, so a large “cracked feeling” can be obtained in any environment.

In addition, the capsule can be destroyed without releasing the cigarette during smoking from the mouth, and you can enjoy a smooth smoking style like never before.

Furthermore, in the case of a tooth breaking capsule, the capsule can be broken smoothly, and the reaction that occurs when the capsule is broken is small. Therefore, even if the capsule is broken during smoking, the ash at the combustion end is less likely to fall off.

Furthermore, there is no possibility that the lipstick adhering to the filter surface sticks to the finger even if the capsule is broken when the user who wears the lipstick holds the filter with his lips and smokes.

<Second embodiment>
FIG. 3 shows a second embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals, and redundant description will be omitted, and parts different from those in the first embodiment will be described below.

In the cigarette shown in FIG. 3, the center position of the fracture capsule 21 for teeth having a bursting volume of 0.7 to 1.0 Vrms is between a distance L from the suction end E of the filter of 9 to 20 mm, more preferably 11 to 15 mm. The tooth destruction capsule 21 is arranged so as to be. With such an arrangement, the user can easily apply teeth to the position of the tooth breaking capsule 21 and the tooth breaking capsule 21 can be easily divided by the teeth.

The chip paper 30 is embossed as an example of the tactile sensation detection unit 40 at the same position (hereinafter referred to as “capsule corresponding position”) where the capsule 21 is arranged in the longitudinal direction of the cigarette. When the user destroys the tooth destruction capsule 21 with teeth, the user cannot visually confirm the position of the tooth destruction capsule 21 but can feel the embossed portion by touching the teeth or lips. The position of the breaking capsule 21 is easily known, and the breaking capsule 21 for teeth is easily broken. The tactile sensation detection unit 40 is defined as a portion that can be detected by tactile sensation.

The tactile sensation detection unit 40 is not limited to embossing, but may be anything that can sense its presence by contact with teeth or lips. Further, the hardness of the filter 20 at the capsule-corresponding portion may be changed.

<Third embodiment>
FIG. 4 shows a cigarette according to the third embodiment. This cigarette includes a cylindrical tobacco rod 10 in which a cigarette filling 11 is wound with a wrapping paper 12, and a cylindrical filter 20 having a structure in which a tooth breaking capsule 21 is provided in a hollow portion between two filter plugs 25. These are connected by chip paper 30 (a filter having such a structure in which a hollow portion is formed between a plurality of filter plugs is referred to as a “cavity filter” in this specification). Winding paper 26 is wound around the two filter plugs 25, and a forming paper 27 is wound around the space where both are spaced apart from each other and disposed through a hollow portion.

The capsule 21, the filter plug 25, the chip paper 50, and the web 26 can be the same as those described in the first embodiment, and the cigarette dimensions are the same as those described in the first embodiment. Things can be used.

Also, the capsule manufacturing method is the same as the capsule described in the first embodiment, and the description thereof is omitted here.

For the formed paper 27, the same paper as the web 26 can be used, and the length of each filter plug 25 in the cigarette longitudinal direction is 5 mm or more. The hollow part should just be a magnitude | size which can accommodate the capsule 21. FIG.

In the case of the filter 20 having the structure in which the tooth breaking capsule 21 is provided in the hollow portion of the cavity filter, the chip paper 30 (an example of the outer peripheral paper) located around the hollow portion serving as the capsule-corresponding position is more than the other portion. Since it easily deforms, it becomes a tactile sense detection unit. Thus, the application to the cigarette having the cavity filter of the present invention is preferable because a tactile sensation detection unit can be obtained without requiring a special configuration. The outer peripheral paper is defined by a sheet-like object that is arranged on the outer periphery in the radial direction of the hollow portion and whose surface is exposed to the outside.

<Measures against bleeding>
As shown in FIG. 5, it is possible to use a permeation-preventing molded paper 52 that prevents penetration of the content liquid of the capsule as the molded paper and not use the web 26.

Examples of the permeation-preventing molded paper 52 include a water-resistant paper having a water-resistant performance, an oil-resistant paper having an oil-resistant performance, a water-resistant oil-resistant paper having a water-resistant and oil-resistant performance, and a wax having a water-resistant or / and oil-resistant performance. Can be used. In such a case, the air permeability may be almost zero.

Further, a gap filling layer 54 is formed between the permeation prevention molded paper 52 and the filter plug 25, and fills the gap between the permeation prevention molded paper 52 and the filter plug 25. As the gap filling layer 54, an adhesive such as glue or hot melt can be used. In addition, when a paper coated with a wax having water resistance or / and oil resistance is used on the inside, the wax can serve as a gap filling layer.

By adopting such a configuration, it is possible to reduce a possibility that the content liquid leaks to the outside when the content liquid comes out of the capsule 21 in the hollow portion.

Of course, an embedding filter can also be constituted by using the web 26 and the gap filling layer 54 that prevent the penetration of the content liquid of the tooth breaking capsule 21 like the above-mentioned molded paper.

<Fourth embodiment>
FIG. 6 shows a cigarette according to the fourth embodiment. The cigarette of the fourth embodiment is provided with a message display section 62 indicating that the tooth breaking capsule 21 is to be divided by a tooth in the same cigarette as in the first to third embodiments.

The display unit 62 may be a character display such as “BREAK BY TEETH” or an illustration as shown in FIG. 7 as long as the message is transmitted to the user. Also, the illustration and characters as shown in FIG. 7 can be expressed by embossing, and the function as a tactile sensation detection unit can be added to the message display unit.

Examples of the packaging member that accommodates the cigarette include a package as shown in FIG. 8A, a film that wraps the package, and the like, and these packaging members may include the message display unit 62. As a method of providing the message display unit, in addition to displaying directly on the packaging member, as shown in FIG. 8B, it can also be realized by putting a member such as paper 64 provided with the message display unit 62 in the packaging member. Is possible.

In addition, each component and each condition setting in each embodiment of the present invention described above can be combined individually and individually unless otherwise specified.

<Rupture volume>
Hereinafter, the definition of the bursting volume in the present invention will be described.

The measurement of the bursting volume was performed with the measurement system shown in FIG. The capsule 21 placed on the stage 91 is pushed from above with a rheometer 92 (Sun® RHEOMETER® CR3000EX (manufactured by Sun Kagaku Co., Ltd.)) and ruptured. The microphone 93 (AT9942 (manufactured by Audio-Technica Co., Ltd.)) and the amplifier 94 (Microphone Amplifier AT-MA2 (manufactured by Audio-Technica Co., Ltd.)) connected to the microphone 93 is installed. Acquisition was performed (the gain setting of the amplifier 94 was measured in the MAX state). Then, the acquired sound data is sent to the personal computer 96 through the AD converter 95, and numerical calculation processing is performed by software (acoustic vibration diagnosis system Visible Wave (manufactured by Mitsubishi Electric Engineering Co., Ltd.)), and an effective value (Vrms) is obtained. Calculated as volume. This volume is defined as “burst volume” in the present specification (the present invention).

The measurement was performed in an indoor environment at a temperature of 22 degrees and a humidity of 60%. As the capsule, a capsule stored in an indoor environment at a temperature of 22 degrees and a humidity of 60% was used.

Next, the relationship between burst volume and capsule burst hardness will be described.

A plurality of capsules whose bursting hardness was changed by changing the film thickness of the capsules were prepared, and the bursting volume of the capsules was measured one by one using the measurement system shown in FIG. The measurement results are shown in FIGS. 10, 11, and 12 are graphs in which the vertical axis represents the burst volume and the horizontal axis represents the capsule burst hardness, and the characteristics of each capsule are plotted. The capsule burst hardness obtained by using the least square method for each plot. A straight line indicating the ratio of volume increase to increase (hereinafter referred to as “increase ratio”) is also shown.

10, 11, and 12, it can be seen that the burst volume increases as the burst hardness increases, and the increase ratio decreases as the burst hardness of the capsule increases. The increase ratio of the capsule to the burst hardness of 10 to 40N (slope of 0.014) is greatly decreased (slope of 0.0039), and the burst hardness of about 70N. If it becomes above, an increase rate will fall further (inclination 0.0013).

The burst hardness of the capsule was measured with a rheometer when the capsule was broken with the aforementioned rheometer. Each capsule changes burst hardness by changing the film thickness as described above, and other conditions such as composition are all the same.

The capsule was prepared by mixing the film substance and the content liquid and dropping. The film substance and the content liquid constituting the capsule were as follows.

(I) Film material (15% by weight based on the weight of the whole capsule)
Main ingredients: Gelatin, starch, gellan gum, glycerin, sorbitol, etc. (ii) Contents liquid (85% by weight based on the weight of the whole capsule)
Medium-chain fatty acid triglycerides (tricapril / glycerine caprate): 83% of the total content
Fragrance (Menthol, Citrus, Orange, etc.): 17% of the total content
The prepared perfume capsule was a sphere having a diameter of about 4.5 mm.

For these reasons, it is preferable that the capsule has a burst hardness of 25 to 70 N from the viewpoint of setting the burst volume to 0.7 to 1.0 Vrms with the burst hardness of the capsule. Further, when the capsule burst hardness is 25 to 40 N, the burst volume can be effectively increased by increasing the capsule burst hardness.

For reference, a plurality of burst volumes of conventional capsules were measured by the same method, and the result was about 0.4 to 0.64 Vrms.
