JP6012291B2 - Cigarette filter and cigarette using the same - Google Patents

Description

  The present invention relates to a cigarette filter including a fragrance capsule and a cigarette using the same.

  Conventionally, a fragrance capsule is incorporated into a cigarette filter, and the fragrance capsule is crushed when cigarette is used, and the scent of the contents liquid is enjoyed when smoking, and the smell of the butts after extinguishing is masked (Patent Document) 1-5). The details of the fragrance capsule are described in Patent Document 6, for example. A cigarette equipped with such a cigarette filter including a fragrance capsule is designed so that the user can enjoy the scent when smoking by crushing the fragrance capsule. When a perfume capsule is loaded into a cigarette filter, it must be ensured that the capsule quality is maintained until the capsule is broken with a finger during smoking.

  However, after manufacturing a cigarette filter loaded with a fragrance capsule, the state of the capsule cannot be confirmed in the distribution process. Moreover, in the distribution process, it is difficult to always manage the temperature and humidity of the cigarette filter loaded with capsules under a certain condition. Therefore, there has been a demand for a cigarette filter including a fragrance capsule to prevent a deterioration in quality due to deterioration of a capsule film during storage.

FIG. 3 is a cross-sectional view showing still another example of a cigarette having a fragrance capsule according to the present invention. FIG. 4 is a diagram illustrating a change in temperature and humidity of the environment where the cigarette package is stored in the example. FIG. 5 is a graph showing the relationship between the trehalose content (% by mass) of the capsule film and the hardness (N) of the capsule.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a cigarette in which a cigarette rod 10 in which a cigarette filler 11 is wound with a wrapping paper 12 and a filter 20 in which a filter plug 22 in which a fragrance capsule 21 is embedded is wound with a winding paper 23 are connected by a chip paper 30. The fragrance capsule 21 has a structure in which the content liquid 21b is wrapped with a film 21a. The diameter of the fragrance capsule 21 is 3.5 to 4.5 mm.

  The cigarette shown in FIG. 2 has the same structure as the cigarette of FIG. 1 except that it has two filter plugs 22a and 22b arranged in contact with each other. In FIG. 2, the first filter plug 22a may be a charcoal filter, and the second filter plug 22b may have a structure in which the fragrance capsule 21 is embedded in an acetate filter.

  Note that the second filter plug 22b may be a charcoal filter. Further, a fragrance may be added to at least one of the first filter plug 22a and the second filter plug 22b.

  FIG. 3 shows a cigarette in which a cigarette rod 10 in which a cigarette filler 11 is wound with a wrapping paper 12 and a filter 20 having a structure in which a fragrance capsule 21 is provided in a hollow portion between two filter plugs 25 are connected by a chip paper 30. Show. A material paper 26 is wound around the two filter plugs 25, and a forming paper 27 is wound around a space where both are separated from each other and disposed through a hollow portion. There are filter plugs that do not have either one or both of the raw paper and the molded paper (in the case of FIG. 1, only the paper that serves as the raw paper and the molded paper is used).

  When smoking such a cigarette, the film 21a of the fragrance capsule 21 is crushed with a finger, but it is desired that the film of the fragrance capsule does not deteriorate during the storage.

  A conventional perfume capsule film includes a base, a gelling agent, a gelling aid, and a plasticizer. For example, denbun or the like is used as a base, and carrageenan or the like is used as a gelling agent in order to enhance the formability of the capsule film. Moreover, a flexible capsule film is formed by adding, for example, glycerin or sorbitol as a plasticizer. Although the capsule film formed with such a composition has a certain hardness, there is a possibility that after the fragrance capsule is produced, the film may absorb moisture or dehumidify due to environmental changes in temperature and humidity, resulting in deterioration.

  Therefore, the present invention adds a trehalose as a water retention agent to the composition of the conventional capsule film, thereby suppressing the film deterioration due to temperature and humidity changes, while maintaining the predetermined hardness required for the capsule for breaking mounted on the cigarette filter. It was possible to maintain this.

  According to the present invention, the film of the fragrance capsule contains 90% by mass or less of the non-gelatin film forming material with respect to the total mass of the film and 10% by mass or more of trehalose as a water retention agent. Trehalose has high water retention, and even if the external environment changes, the effect of temperature and humidity changes on the capsule itself is moderate. For this reason, according to the present invention, deterioration / disintegration of the capsule film can be suppressed during storage, and the quality is maintained as a cigarette filter loaded with a fragrance capsule, which is very effective.

  In addition, cigarettes are manufactured by connecting cigarette filters to tobacco rods. For example, the cigarette is formed into a bundle of 20 pieces, and then accommodated in an outer box in a state of being wrapped in aluminum inner paper. Further, the entire outer box is wrapped with a transparent film to complete the package. In the process of manufacturing a cigarette package, the transparent film is heat sealed. In this way, even when the package itself is heated, the fragrance capsule containing trehalose is not easily affected by heating, so that deterioration of the capsule film can be suppressed.

  In the present invention, the content of the non-gelatin film-forming material with respect to the mass of the entire film is preferably more than 70% by mass, and the content of trehalose with respect to the mass of the entire film is preferably less than 30% by mass. When the trehalose content is 10% by mass or more and less than 30% by mass, preferably 10% by mass or more and 20% by mass or less, based on the mass of the entire film, a capsule having an appropriate hardness can be obtained.

  After the perfume capsule is loaded into the cigarette filter, it is impossible to keep the ambient temperature and humidity constant until the consumer destroys the perfume capsule during cigarette / packaging manufacturing and distribution process. Since the state of the capsule cannot be visually confirmed after production, the fragrance capsule according to the present invention is effective for application to a cigarette.

  In the present invention, the film-forming material contains, for example, a base and a gelling agent. As the base, for example, starch, dextrin and the like are used. Examples of gelling agents include gellan gum and carrageenan. In the present invention, 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. Examples of the plasticizer include glycerin and sorbitol. In the present invention, the film forming material may further contain a colorant.

  The content of the base is 25 to 50% by mass, the content of the gelling agent is 10 to 20% by mass, the content of the gelling aid is 5% by mass or less, and the content of the plasticizer is 20 to 30% by mass. Preferably there is.

  In the present invention, for example, menthol, plant essential oil or the like can be used as the fragrance contained in the content liquid of the fragrance capsule.

  In the present invention, for example, medium-chain fatty acid triglyceride (MCT) can be used as a fragrance solvent contained in the content liquid.

  In the present invention, the content liquid may further contain other additives such as a pigment, an emulsifier, and a thickener.

  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.

In the cigarette of the present invention, it is preferable to use oil-resistant paper for the forming paper 27 shown in FIG. 2, for example, which is in direct contact with the fragrance capsule 21 of at least chip paper and / or filter wrapper. Among oil resistances, for example, oil-resistant paper manufactured by Nippon Paper Papillia Co., Ltd. is preferable because no film or fluororesin is used. Table 1 shows the characteristics of the oil-resistant paper manufactured by Nippon Paper Papillia Co., Ltd.

  Examples of the present invention will be described below.

[Examples 1A to 1F]
A content liquid of a fragrance capsule was prepared using menthol as a fragrance, medium chain fatty acid triglyceride (MCT) as a solvent, an emulsifier and the like.

  Prepare starch, gellan gum (gelling agent), calcium chloride (gelling aid), glycerin (plasticizer), sorbitol (plasticizer), trehalose, and colorant as the coating substances in the proportions shown in Table 2, Mixing with the content liquid, a fragrance capsule having a diameter of 4.5 mm was prepared by a dropping method. The amount of change in trehalose content was adjusted by the starch content. The cigarette filter shown in FIG. 2 was produced using each of the perfume capsules, and the cigarette shown in FIG. 2 was further produced.

  The manufactured cigarette was packaged in a normal small box with 20 boxes. This small box is stored in an environment where the temperature changes between 25 ° C. and 55 ° C. and the humidity changes between 65% and 35% as shown in FIG. The breakdown of the encapsulated film was investigated. Specifically, the number of capsule films disintegrated after 2 weeks, 4 weeks, 2 months, and 3 months was examined. The results are also shown in Table 2.

Table 2 shows that when the trehalose content in the capsule film is 10% by mass, the capsule film does not collapse even after 4 weeks, and when it is 20% by mass, the capsule film does not collapse even after 2 months. .

[Examples 2A to 2F]
In the same manner as described above, a fragrance capsule content liquid was prepared using menthol as a fragrance, medium chain fatty acid triglyceride (MCT) as a solvent, an emulsifier and the like.

  Prepare the starch, gellan gum (gelling agent), calcium chloride (gelling aid), glycerin (plasticizer), sorbitol (plasticizer), trehalose, and colorant as the coating substances in the proportions shown in Table 3 above. Mixing with the content liquid, a fragrance capsule having a diameter of 4.5 mm was prepared by a dropping method.

  The hardness (N) of each of the obtained fragrance capsules was measured with a hardness measuring instrument (Sun Kagaku Co., Ltd., rheometer). Table 3 shows the average hardness values measured for 20 flavor capsules of the same specification. FIG. 5 shows the relationship between the trehalose content (% by mass) of the capsule film and the hardness (N) of the capsule film.

  It can be seen from Table 3 and FIG. 5 that the trehalose content is preferably 10% by mass or more and less than 30% by mass with respect to the mass of the entire capsule film.

When the trehalose content is 30% or more, the moisturizing property of trehalose is high, so the fragrance capsule itself becomes soft, and when the fragrance capsule is crushed with a finger from the outer periphery of the filter, the breaking sound is weakened, and a split feel is obtained. I can't. That is, the broken capsule used for the cigarette filter needs to have a certain hardness, and the trehalose content is also regulated to a predetermined amount with respect to the total capsule coating. At this time, if the content of the plasticizer (glycerin, sorbitol, etc.) with respect to the mass of the entire capsule film is 20 to 30% by mass, the hardness required for the capsule film can be maintained. Thus, with respect to the mass of the entire capsule film, the trehalose content is 10% by mass or more and less than 30% by mass, and the plasticizer (glycerin, sorbitol, etc.) content is 20 to 30% by mass. The quality can be maintained until the capsule is destroyed during smoking while maintaining the hardness of the capsule film.
