Description

Sputum sac and filter cigarette with the sac

The present invention relates to a sac that is suitable for a cigarette filter, and a filter cigarette that uses the sac.

Conventionally, there have been various proposals for a technique of installing a so-called water sac in a filter disposed at one end of a cigarette to improve the inhalation of flavor. Further, water or a solution containing tobacco extract, flavor, or the like is used as a filling liquid in the sac, and it is intended to suitably improve the inhalation scent.

Specifically, in the past, there have been various proposals for a cigarette water filter in which a water sac that is easily destructively filled with a specific filling liquid (for example, water) is filled between the filter materials, or a cigarette that is applied to such a filter. . When the user (smoker) smokes, when the user (smoker) smokes, the finger is pressed by the filter portion to apply an external force in a crushing manner, the specific portion of the sac is broken, and the internal filling liquid is ejected and impregnated. In the filter material.

Since it has been tried to prevent the water sac as described above from being destroyed without applying a certain amount of external force, the internal filling liquid does not leak, and the treatment is also easy. Therefore, if such a water sac is prepared in advance, a filter for filling the sac can be manufactured by simply changing the equipment of the conventional filter manufacturing plant (Patent Document 1, Patent Document 2, Patent Document 3, etc.) .

As described above, in the water sac of the conventional cigarette, when the user applies an external force by sandwiching the filter with a finger, a portion that is easily broken (a breakable portion) is provided, and the internal filling liquid is discharged (released).

However, the conventional sac has been focused on the fact that it can be reliably destroyed when subjected to an external force, but does not care about the extent to which the filling liquid (content) completely flows out of the sac.

Therefore, in the conventional sputum sac, even if the breakage portion is broken as described above, the contents are discharged, and the filling liquid may remain in the sac after the destruction. This is because the ratio of the outflow of the contents varies depending on the number of times the user's destructive force and the destructive action occur, and the same cigarette has a difference in inhaled aroma.

An object of the present invention is to provide a structure having a structure in which the entire capsule can be broken into a flat shape to cause a full amount of the contents to flow out when subjected to an external force, a capsule suitable for use in a cigarette filter, and a filter cigarette using the capsule.

Further, the filling liquid held by the capsule of the present invention is not particularly limited, and may be a liquid, a solid or a content of at least fluidity composed of the two. That is, the present invention contains, in addition to the conventional sputum sac, and further contains a small solid like a microcapsule, and as a whole, a sac that retains the fluid content as a whole.

The above objectives are achieved by a sac that is characterized by: a slightly cylindrical capsule having an open end and opening an internal space, and a cover member closing the open end, wherein the liquid formed by the bladder and the cover member is held by a liquid, a solid or the like The at least the fluid content of the capsule body and the lid member are formed of an elastically deformable material, and the capsule is formed by breaking the contents of the capsule body and flowing out of the contents when an external force is applied.

The above-mentioned balloon body can be integrally planarized when subjected to the aforementioned external force, Further, when the capsule is elastically deformed by the external force, it is formed by being broken by the pressure of the content.

Further, the cover member includes a flattening structure that is flattened in accordance with deformation of the balloon body.

Therefore, it is preferable that the capsule body includes the capsule body portion that forms a hollow polygonal column shape, and a polygonal pyramid-shaped head portion that forms the other end portion corresponding to the shape of the capsule body portion, and constitutes the capsule body portion. In the plurality of corner post parts, the adjacent two corner post part portions are connected by a first joint portion that expands the inner corner formed by the equiangular column component portion, and the plurality of corner pyramid component portions that constitute the head portion are adjacent to each other. The two pyramidal part portions are connected by a second joint portion that expands the inner corner formed by the equal-angle tapered portion, and is formed such that the entire capsule body can be flattened when the external force is applied.

Further, it is preferable that the number of the corner post parts and the pyramid part are each an even number.

Further, the first joint portion and the second joint portion thin portion are formed, and the second joint portion is formed to be thinner than the first joint portion.

In addition, the desired head portion protrudes outward from the body portion of the capsule body. structure.

The flattening structure of the cover member may include a polygonal pyramid-shaped member having the same shape as the head portion, or a sealing film that is stretched over the open end.

Further, the above-described polygonal pyramid-shaped member as the cover member is provided so as to be inserted into the inside of the capsule body portion.

Further, the above contents may contain water, water to which a fragrance is added, or water containing a destructible fine solid containing a fragrance.

Moreover, the aforementioned elastically deformable material is selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyethylene terephthalate, polyvinyl alcohol and polydecylamine. One of the food plastic materials.

Further, the above object can be attained by a filter cigarette comprising a filter having the sac of any of the above.

Further, the filter is formed to include a first filter element located on the cigarette side and a second filter element located on the suction side, and a storage space secured between the first and second filter elements. In the storage space, the head portion is configured to be housed in the crotch in a posture toward the first filter element side.

When the hernia sac of the present invention is designed to be flattened when it is deformed by external force deformation, a part of the sac is destroyed, and the fluid content inside is discharged, and the sac is discharged to the outside.

Therefore, by attaching the filter bag to the filter cigarette with the capsule, when the capsule is broken, almost all of the retained contents can be moved toward the filter side, and the inhalation fragrance improved by the content can be uniformized. The goal.

Fig. 4 is an enlarged schematic view showing the state of the capsule in combination with the capsule of Fig. 2 and the lid member of Fig. 3.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a view showing an example in which the sac of the present invention is used in a filter attached to a filter cigarette FC.

The filter cigarette FC is configured by arranging a filter rod 101 at one end of a cigarette 100 in which a tobacco is rolled into a stick shape. The filter rod 101 is provided with a filter made up of two filter elements to be described later in a flexible casing 102, and the bush 102 is made of, for example, a hollow paper tube. Further, the cigarette 100 and the filter rod 101 are connected by a tip paper 103 which is attached by hooking the two to form a filter cigarette FC.

In the bushing 102, a first filter 104a as a first filter element and a second filter 104b as a second filter element are disposed at both ends. The materials of the filters 104a, 104b are the same as those of the filter material used in conventional filter cigarettes, that is, may be acetate fibers, and may further contain charcoal. In addition, a paper filter or the like can also be used.

The first filter 104a at one end of the bushing 102 is a cigarette side, and the second filter 104b at the other end constitutes a suction port. Since the first filter 104a and the second filter 104b are arranged at intervals as described above, the space between them can be secured as a storage. The space 105 houses the capsule 1 therein.

The capsule 1 includes a substantially cylindrical capsule 10 having an opening at one end 10a to open the internal space SP, and a lid member 20 that closes the open end 10a. On the other hand, the fluid content WA is held in the sealed space (the closed internal space SP) formed by the capsule body 10 and the lid member 20. Further, the capsule body 10 and the lid member 20 are formed of an elastically deformable material, and are configured to break the aforementioned capsule body 10 by an external force and to flow out the content WA.

In addition, the first figure is an example in which the capsule 1 is simply placed in the housing space 105 (groove) between the first filter 104a and the second filter 104b, but is not limited to such a form. For example, the same fiber as the filter material may be disposed on the periphery of the capsule 1. Further, if desired, at least one of the liner 102 and the outer layer paper 103 formed as a paper tube is a water-resistant person.

Further, the capsule 1 will be described in detail with reference to Figs. 2 to 4 .

Fig. 2 is an enlarged schematic view of the capsule 10 of the above-described capsule 1 . Further, Fig. 3 is an enlarged schematic view of the cover member 20 of the capsule 1. Next, Fig. 4 is an enlarged schematic view showing a state in which the capsule 10 and the lid member 20 are combined as the capsule 1.

Furthermore, the second (a) is a perspective view of the capsule 10, the second (b) is a plan view of the capsule 10, and the second (c) is the AA section of the second (b). Fig. 2(d) is a BB sectional view in Fig. 2(b), and Fig. 2(e) is a CC sectional view in Fig. 2(c), and then, Fig. 2(f) is a system A bottom view of the capsule 10. The figures 3(a) to 3(f) are the same as Fig. 2, and are diagrams showing the cover member 20. Then, Fig. 4(a) is a plan view of the capsule 1, 4(b) is a view of the AA in Fig. 4(a), and Fig. 4(c) is a BB in Fig. 4(a). Sectional view.

In Fig. 2, the capsule 10 is formed by forming an even-numbered polygonal column with a hollow shape. The capsule body portion 11 having a shape of a hexagonal column (exemplified by a hexagonal column shape) and a head portion 15 having an even-numbered polygonal pyramid shape (exemplified by a hexagonal pyramid shape) corresponding to the shape of the capsule body portion 11 are formed. On the other hand, the head portion 15 is integrally formed so as to protrude outward from the capsule body portion 11.

The capsule body portion 11 includes six corner post parts 12a to 12f which are formed in a cylindrical hexagonal column shape (12c to 12e on the back side in the second (a) view are not shown), and are adjacent to each other. Six joint portions (first joint portions) 13a to 13f that are expandably connected to each other at an inner corner formed by the component portions between the equiangular column component portions (13c to 13e on the back side in the second (a) figure) It is formed without being shown).

Then, the head 15 is also formed in the same manner. That is, the head portion 15 includes six pyramidal component portions 16a to 16f constituting a hexagonal pyramid shape, and the inner corners formed by the respective component portions adjacent to the equiangular pyramid component portions are connected to each other in a contractible manner. Six joint portions (second joint portions) 17a to 17f are formed.

The capsule body portion 11 and the head portion 15 are integrally formed of a plastic material having a moderate elasticity to constitute the capsule body 10.

Further, it is preferable that the annular connecting portion 18 located between the capsule body portion 11 and the head portion 15 is also a part portion adjacent to the corner post portion portions 12a to 12f and the pyramid member portions 16a to 16f (this is preferable). At this time, for example, the corner portion formed by the corner post portion 12a and the pyramid component portion 16a) forms a contractible joint portion (third joint portion) (see Fig. 2(a)).

Therefore, when the capsule body portion 11 of the capsule body 10 is subjected to a force other than crushing it, the joint portion at one of the opposing positions is bent in a U shape, and the inner angle is reduced to a minimum angle of 0 degrees. The other joints are extended, and the inner corners are expanded to a maximum angle of 180 degrees. As a result, the capsule body portion 11 can be in the form of being folded into two layers. Then, since the joint portion (second joint portion) of the head portion 15 is bent along with the deformation of the capsule body portion 11, the head portion 15 is also deformed into a fold. In the form of two layers, the entire capsule 10 is flattened. At this time, the space SP in the capsule body 10 is in a state of almost elimination.

Then, when the joint portions (second joint portions) 17a to 17f provided on the head portion 15 are deformed by an external force, they are easily broken by other pressures based on the pressure of the fluid content WA held from the inside. form. For example, in the capsule body 10 formed of a plastic material, the joint portions (second joint portions) 17a to 17f provided on the head portion 15 side are compared with the joint portion provided on the trunk body portion 11 (first The joint portions 13a to 13f are formed to be thinner, and can be easily set to be easily destructible. That is, the capsule 1 is realized by the thin-walled structure.

The second (e) diagram enlarges the portion of the joint portion (thin portion) 17e of the head portion 15, and the wall thickness t of the thin portion is formed in a relatively thin manner as compared with the original wall thickness T of the head portion 15. When the internal angle formed by the adjacent component parts is expandable, the structure is easily broken (easy to cut). In the second (e) diagram, the inside is cut into a V shape (the cutting angle α is, for example, 30°), and it can be confirmed that it is in a thin state.

On the other hand, the joint portions (first joint portions) 13A to 13F and the joint portion 18 (third joint portion) formed in the capsule body portion 11 are simply expanded (retracted) by the internal angle. Formed in a way that is not destroyed.

Furthermore, the cover member 20 that closes the open end 10a of the balloon body 10 will be described with reference to Fig. 3 . The lid member 20 is formed into a flattening structure that is flattened by the deformation of the capsule body 10 which can be planarized as described above. As for the cover member 20, when the capsule body 10 is flattened, it is flattened so as not to cause obstruction. Therefore, it is possible to obtain a member in a state in which the contents are discharged when the joint portions 17a to 17f of the head portion 15 are broken. Therefore, in order to prevent the cover member 20 from being broken by the pressure of the contents or falling off from the open end 10a before the joint portions 17a to 17f are broken, It is fixed by an adhesive or a heat fusion treatment or the like.

Fig. 3 is a view showing a cover member 20 which is formed into a suitable structure, and has a pyramid shape similar to that of the above-described head portion 15. That is, the cover member 20 shown in Fig. 3 also includes six pyramidal component portions 21a to 21f constituting a hexagonal pyramid shape, and six joint portions that are flexibly coupled between the individual pyramidal component portions ( The fourth joints 22a to 22f are formed. As long as the cover member is formed in such a structure, when the capsule 10 is deformed and flattened as described above, it will be flattened. Further, although the joint portions 22a to 22f of the lid member 20 are also easily bent, it is desirable to form a thin portion which is not broken.

The cover member 20 is formed into a hexagonal ring frame portion 23 at the periphery of the adjacent six pyramid component portions 21a to 21f. By inserting the ring frame portion 23 into the inner circumference of the open end 10a of the capsule body 10, the space SP in the capsule body 10 becomes a sealed space, and a state in which the content WA can be held is formed. That is, as shown in Fig. 4, in the open end 10a of the capsule 10 of Fig. 2, the capsule 1 can be formed by fitting the cover member 20 of Fig. 3.

Further, as shown in Fig. 4, the cover member 20 has a hexagonal pyramid shape (even polygonal shape) similarly to the head portion 15 of the capsule body 10, but the protruding direction (the direction of the apex of the pyramid) is different. In other words, the cover member 20 does not protrude outward from the inside of the capsule body portion 11, as it does not protrude outward as in the head portion 15. When such a method is formed, for example, compared with a case where the lid member 20 is formed in a flat plate shape and mounted vertically, it is expected that the strength (extra-destructiveness) of the external force can be weakened, and the folding can be easily performed (flattening property is improved). Further, when the cover member 20 is deformed in this manner, the fluid content is reduced due to the narrowing of the sealed space, and the internal pressure is increased, and it is expected that the joint portion 16a to 16f which is the head 15 which is easy to break the structure is damaged. The secondary effect.

The capsule body 10 and the cover member 20 are formed of an elastically deformable material. The material to be used is a food selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyethylene terephthalate, polyvinyl alcohol and polydecylamine. Use plastic materials.

Further, as described above, the contents of the capsules 1 are filled with the contents WA, and the contents WA are not limited to the conventional filling liquid as long as they have fluidity which can flow out when the capsules are broken, and may be liquid, solid or both. Former.

In other words, as the content WA, any of water, a hydrophilic perfume, and a hydrophobic fragrance can be used. In the case of a hydrophobic fragrance, it can be adjusted to be in an emulsified state, and a solvent such as propylene glycol or ethanol can be used. More specifically, as the content WA, for example, a solution for dissolving sugar, tobacco extract, flavor, or the like in water or a solution containing water as a matrix such as brandy may be used. In addition, anti-deterioration liquid can be mixed if necessary.

In addition, as for the content WA, a fine solid such as a microcapsule (scented sac) which is used for the fragrance of the fragrance can be used, and in the content WA, the fragrance sac can be made into a floating liquid. .

Again, referring to Fig. 1, the capsule 1 is arranged such that the head 15 of the capsule 10 approaches the first filter 104a on the cigarette side. In other words, since the content ingested is the first filter 104a that is farther from the suction port, the content does not flow out to the suction port and the suction taste is impaired.

Further, the outer diameter of the capsule 10 of the above-mentioned capsule 1 is relatively small compared to the inner diameter of the liner 102, whereby the inner surface of the liner 102 and the capsule can be clearly as shown in Fig. 1. Between the outer faces of 10, the smoke from the cigarette 100 is restrained by the presence of the sac 1 and passes through the filters 104a, 104b, ensuring sufficient passage of the smoke to the suction port. Smoke flow path.

Next, the operation of the user (smoker) who smokes the filter cigarette FC having the above-described capsule 1 will be described. The user holds the filter rod 101 with a finger as indicated by an arrow AR in Fig. 1, and then, when the filter rod 101 is pressed by the outside, the internal capsule 1 is The bushing of the filter rod 101 is elastically deformed together.

Here, the capsule body 10 is formed by a capsule body portion 11 having a hexagonal prism shape and a head portion 15 having a hexagonal pyramid shape, and the lid member 20 for plugging the open end 10a of the bottom portion is also a hexagonal pyramid shape. Therefore, even when the external force is initially applied, even if the capsule body portion 11 is temporarily unstable, it is in a state of being easily perpendicular to the axis acting on the external force, and finally the entire capsule 1 is flattened. At this time, the pressure of the content WA sealed in a liquid-tight state acts on the periphery, but since the joint portions 16a to 16f of the head portion 15 are set to be easily broken, at least a part of the joint portion is broken by pressure. .

Thereby, the content WA in the capsule 1 flows out in the direction of the first filter 104a. Thereafter, since the entire capsule 1 is flattened as a whole, the internal space is substantially eliminated, so that the entire amount of the contents is surely discharged without remaining in the container.

Then, the user ignites the filter cigarette FC to smoke. When smoking, as described above, since the first filter 104a is impregnated with the contents, the content of the water-soluble component contained in the smoke stream from the cigarette 100 can be reduced by the contents, and the inhalation flavor can be improved by the added flavor. At this time, since the contents in the sac are all in a state of almost full outflow, the user can taste a uniformly improved inhalation scent.

Hereinafter, an embodiment of a filter cigarette with a sac of the present invention will be described.

(Example)

The contents are made of water sacs, which are suitable for use with filter cigarettes as an example of the above-mentioned sac.

As a edible plastic material, a low-density polyethylene (NOVATEC LD, manufactured by Nippon Polyethylene Co., Ltd.) was used to produce a water sac by injection molding. The joint portion (thin portion) is formed by a mold used for molding.

In the state in which the open end of the body portion of the sac is open, 45 mg of distilled water is injected thereinto, and the lid member is fitted (installed) at the open end to make the inside a dense liquid state, and then the back of the cover member is gathered. A guanamine (arylamine)/low-density polyethylene laminated sheet (NY#15/DL/AJ-1, 70 μm, manufactured by TAMAPORI Co., Ltd.) was heat-sealed to completely seal the leeches which are examples of the sac of the present invention. bag.

The filter portion of the commercially available filter cigarette was modified to produce a filter cigarette with the above-described water sac.

Specifically, two acetate cellulose filters (2.5Y/35000) cut into a length of 10 mm were prepared as the first filter (104a) and the second filter (104b). The filter that was originally installed was removed using tweezers, and instead, the two filters were separately arranged at 7 mm to form a storage space (105) in which the above-described water sac (1) was installed. The head of the head of the otter (15) is attached to the side of the cigarette (100). The outer paper (103) and the bushing (102) are closed to form a filter cigarette (FC).

The finger portion of the cigarette is pinched by a finger to break the inner water sac. When the filter portion is decomposed for confirmation, it is confirmed that the inside water is moved to the first filter on the side of the cigarette (100), and the inside of the capsule is free of water.

As described above, the capsule of the present invention is configured to be flattened when subjected to an external force, and when it is broken and the contents of the inside are discharged, it can be made Completely exhausted. Accordingly, by using the filter cigarette with such a sac in the filter portion, the improved inhalation flavor can be improved when the sac is used.

The above description is based on the premise that the filter material is immersed in the state in which the filter material is impregnated. However, in the case of the filter cigarette FC with the sac of the present invention, the cigarette 100 can be enjoyed without damaging the sac. The original inhalation of the fragrance. That is, the filter cigarette FC used in the present invention can be used as a usual filter cigarette according to its preference, even if it does not damage the capsule body, since it ensures the passage of the smoke from the tobacco 100 to the suction port. And smoking.

Furthermore, the invention is not limited to the embodiments described above.

In terms of the shape of the capsule body portion 11, the capsule body portion 11 has an even-numbered polygonal column shape from the viewpoint of a suitable shape, and the foregoing embodiment has a hexagonal column shape, but may also have an 8-corner column shape. 10 corner column shape, etc.

However, since the capsule of the present invention is formed of a resilient plastic material, even in the case of the above-described even polygonal column shape (for example, the case of the capsule body portion and the head of the odd-numbered 9-corner column shape) In the case of destruction, it is expected to be flattened as described above. Further, the shape of the capsule body portion 11 is not particularly limited as long as the material to be used is deformed when the external force is applied to the side surface and finally flattened.

Further, in the foregoing embodiment, the cover member 20 that closes the opening of the capsule body 10 is not limited to the same shape as the head portion 15. When the capsule body 10 is flattened, the content cannot be leaked without hindering the deformation of the capsule body 10, and it may be a film-like heat seal or the like. When such a film is used, the opening edge 10a of the capsule 10 can be followed by a thermoplastic adhesive. As the adhesive, for example, an adhesive polyolefin resin, a low molecular weight polyethylene, and EVA (ethylene vinyl alcohol) as a main component of a hot melt adhesive can be used.

Further, the above embodiments are illustrative of a capsule suitable for use with a filter cigarette. However, the capsule of the present invention is not limited to the filter attached to such a cigarette. That is, the capsule of the present invention can also be applied to a commercially available water-smoking article attached to a cigarette. In the case of a water hood, most of the bushings are formed of synthetic resin, and the aforementioned sac of the present invention can be disposed inside. In the case of a water pipe, the filter material can be designed to have only one side of the content discharge side.
