Description

Capsule for smoking articles, filter equipped with the capsule for the smoking article, and smoking article having the filter

The present invention relates to a capsule for a smoking article in which a liquid for a smoking article such as a cigarette with a filter is enclosed, a filter in which the capsule for the smoking article is mounted, and a smoking article having the filter.

When smoking, the liquid infiltrating into a smoking article such as a cigarette with a filter or the like in which water or an aqueous solution containing an additive for inhaling a fragrance is dissolved can improve the characteristics of the inhaled flavor in the mainstream smoke, and Add different inhaled aromas to mainstream smoke. At this time, the liquid system is placed in the filter body in a state of being sealed in the capsule, and the user breaks the capsule before the smoking, and the liquid is ejected from the capsule to allow the liquid to permeate into the filter. In detail, the user applies an external force to the capsule from the outside of the filter to sandwich the capsule between the fingers to destroy the capsule.

However, since a capsule formed of a polysaccharide such as gelatin is water-soluble, it is not suitable for encapsulation of a hydrophilic liquid, and such a water-soluble capsule is usually limited to use in the sealing of a hydrophobic fragrance or the like. phase In this case, the capsule formed of the synthetic resin is water-insoluble, is suitable for encapsulating a hydrophilic liquid, and has excellent shape stability, but is harder than a water-soluble capsule. Therefore, for a synthetic resin capsule, the following various kinds are easy to be used. Countermeasures against damage.

For example, when the capsule has a cylindrical shape, a plurality of elongated grooves extending radially in the end wall of the capsule are formed, and the grooves are broken when the capsule is subjected to a crushed external force, and the contents can be ejected from the capsule. Liquid (Patent Document 1).

Further, there is also a capsule including a sealed capsule which is broken when the external force is applied to eject the content liquid (Patent Document 2).

Further, there is also known a capsule in which two capsule halves are fitted through an annular seal, and the capsule is crushed to break the seal to eject a liquid (Patent Document 3).

First, the first embodiment will be described.

Fig. 1 is a view showing a case where a filter for a capsule for a smoking article according to the first embodiment of the present invention is used for a cigarette CG as a smoking article, and Fig. 2A shows a device for taking out the cigarette CG. The capsule CA-1 of the filter FL, and the 2B diagram shows a front view of the central portion of the front end wall of the capsule CA-1.

In the first drawing, the cigarette CG having a filter is configured by arranging a filter FL at one end of a cigarette body 100 in which a thin paper is wound into a tobacco rod. The filter FL is provided with a filter main body portion composed of two cylindrical (rod-shaped) filter units 202 and 203 in a flexible casing 201, and the outer casing 201 is, for example, a sheet ( The sheet material is rolled up and then formed into a cylindrical shape at the end. Further, the cigarette body 100 and the filter FL are connected to each other through a tip paper 101 that is placed in the both. Make a cigarette CG with a filter.

In the above casing 201, they are arranged to be spaced apart from each other. The first filter portion 202 serving as the first filter element at both ends and the second filter portion 203 serving as the second filter element. As the material of the filter portions 202 and 203, the same material as that used for the conventional cigarette having a filter, that is, acetate fiber, and further containing charcoal can be used. Charcoal). In addition, a paper filter or the like can also be used. The materials of the filter portions 202, 203 may be the same or different.

The first filter portion 202 located at one end of the outer casing 201 is on the cigarette side, and the second filter portion 203 located at the other end constitutes a suction nozzle. The first filter portion 202 and the second filter portion 203 are disposed apart from each other as described above, and the middle portion thereof is the storage space 204, and strictly includes the first filter portion 202 and the second filter portion 203. The storage space 204 in the middle thereof constitutes a filter body portion. The capsule CA-1 is housed inside the storage space 204.

Here, referring also to FIG. 2A showing the capsule CA-1, the capsule CA-1 is substantially hexagonal columnar (substantially cylindrical), and a liquid is sealed inside the capsule CA-1 by a cover member. In the state in which the filter FL in which the capsule CA-1 is mounted is provided in the cigarette CG, the longitudinal direction of the cigarette CG and the filter body portion will be referred to as the axial direction, and the cigarette body 100 side in the axial direction will be referred to as The front end side and the filter FL side in the axial direction are described as the rear end side as follows.

The capsule CA-1 is composed of a capsule body 10 and a cover member 13 (end wall) which is composed of a cylindrical peripheral wall 11 and a front end wall 12 for closing the opening of the front end of the peripheral wall 11. (end wall) The cover member 13 is configured to close the rear end opening of the peripheral wall 11.

The capsule CA-1 of this configuration is inside the storage space 204, and is indicated by a dotted line in the axis A1, the first figure, and the second AA of the filter body portion indicated by a one-dot chain line in Fig. 1 . The axis A2 of the capsule CA-1 is placed coaxially. Further, the capsule CA-1 does not need to have the axis A2 coaxial with the axis A1 of the filter body portion, and may be parallel to the axis A1 of the capsule body portion and the axis A2 of the capsule CA-1.

The vertical cross section of the peripheral wall 11 of the capsule body 10 has a substantially regular hexagonal shape with respect to the axial direction, and has six peripheral wall faces 11a and a joint portion 11b formed between the peripheral wall faces 11a. Although not shown, a groove along the axial direction is formed on the inner surface of the joint portion 11b, so that the capsule body 10 is more easily deformed with respect to an external force in a direction perpendicular to the axial direction.

The front end wall 12 of the capsule body 10 is composed of a central portion 20 and a peripheral portion 21 which is a plane perpendicular to the axial direction of the axial portion, and the peripheral portion 21 is from the central portion 20 to the peripheral wall. The front end of the 11 extends obliquely with respect to the axial direction.

The central portion 20 is a regular hexagonal plane which is similar to the cross-sectional shape of the peripheral wall 11 of the capsule body 10 which is perpendicular to the axial direction. The peripheral edge portion 21 is composed of six faces extending from the respective sides of the center portion 20 to the side of the front end side of each of the peripheral wall faces 11a.

Further, in the outer surface of the center portion 20, a plurality of groove portions 22 which are linear are formed. The groove portion 22 is formed as a thin-walled region thinner than other regions in the central portion 20, for example, a V-shaped cross section or a U-shaped cross section. ditch.

In the present embodiment, as shown in Figs. 2A and 2B. It is to be noted that the groove portion 22 is formed by connecting six straight lines between the vertices of the central portion 20 of the regular hexagon, and the six-pointed star in which the right and left opposite triangles overlap each other is drawn. Therefore, in the center portion 20, as shown by the asterisk in FIG. 2B, the intersection point 23 (joining point) where the six linear groove portions 22 merge with each other is formed.

Preferably, for the preferred synthetic material of the capsule body 10, it is preferably selected from, for example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyparaphenylene. A plastic material for foods of any one of a group consisting of polyethylene terephthalate, polyvinyl alcohol, and polyamide.

The cover member 13 is formed by using an adhesive or a heat fusion process or the like. It is fixed to the capsule body 10 so that the contents of the capsule CA-1 do not leak. Although the same material as that of the capsule body 10 can be used, as a film material such as a laminate film, the opening can be closed by heat sealing. When such a sealing film is used, it is only required to be adhered to the opening edge of the capsule body 10 by a thermoplastic adhesive. In the case of the adhesive, for example, a polyolefine resin, a low molecular weight polyethylene, and an EVA (ethylene vinvl alcohol) can be used. A hot melt adhesive or the like as a main agent. On the other hand, when the capsule body 10 is crushed and flattened, the lid member 13 may be formed in a shape including a flattened shape of a taper which protrudes inwardly so as not to be an obstacle.

Furthermore, in terms of the liquid enclosed in the capsule CA-1, The one which can improve the flavor of a cigarette can be suitably selected, for example, any of water, a flavor which is hydrophilic with water, and a flavor component which is hydrophobic can be used. In the case of a hydrophobic flavor component, it may be formulated in an emulsified state, and a solvent such as propylene glycol or ethanol may be used. More specifically, for example, a solution in which sugar, tobacco extract, flavor, or the like is dissolved in water, or a water-based solution such as branty can be used as the liquid. Further, if necessary, a chemical solution for preventing deterioration or the like may be mixed. Further, as the liquid, a fine solid such as a microcapsule (scented capsule) containing a fragrance may be used, or a form in which the above-mentioned flavor capsule is floated in a liquid liquid may be used as a liquid. .

In addition, it is preferable to use the outer casing 201 and the wrapping paper. At least one of 101 has a structure in which a sheet having a water resistance function is used to prevent the liquid from leaking to the outer peripheral portion.

The capsule CA-1 constructed in this manner receives the force F from the user (the force of pinching the filter portion with the finger) by the filter FL of the cigarette CG as indicated by the white arrow on the black background of Fig. 1 . When the front end wall 12 is broken, the internal liquid is ejected to one of the first filter portions 202 as indicated by the black thick arrow symbol in Fig. 1 .
