DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is smoking for incense, i.e. related to <br/> mosquito and incense for Buddhist altar, more particularly, the combustion time without the possible long risk of fade-out at the time of combustion, thus Even if the weight and size are reduced, the same smoking time as that of the conventional incense can be secured, and the volatilization rate of the active ingredient is excellent.
Related to incense sticks for smoking . In this specification, smoke
“Incense sticks” means mosquito coils and Buddhist altar incense sticks.
Below, when these are collectively referred to simply as incense).

[0002]

2. Description of the Related Art As is well known, incense sticks such as mosquito coils and Buddhist altar incense sticks are combustible or supportive agents such as pyrethrum extract cake powder, wood powder, foliage powder such as cedar and tea, tub powder, corn starch. The base material is a paste such as glue, a fungicide such as dehydroacetic acid, a pigment, etc., and water is added to a mixture of active ingredients such as insecticidal components for mosquito coil and incense stick for Buddhist altars. It is manufactured by extrusion punching or extrusion to a weight and size such that it smokes for about 7 hours for mosquito coils and about 40 to 50 minutes for Buddhist altar sticks, and then dried.

[0003] The conditions required as a base material for such incense sticks are: (a) when the incense stick is burned, it is kept burning for a predetermined time without extinguishing; (ii) the volatilization rate of the active ingredient is high; (C) there is no irritation and no off-flavor during smoking, and (d) it has good machine forming aptitude in the kneading, extrusion punching step or extrusion molding step.
And (e) stable and inexpensive supply.

Conventionally, as a base material of mosquito coils, pyrethrum extract meal powder, wood flour, foliage, and the like occupy a large portion thereof.
Pyrethrum extract meal powder has less irritation and off-flavor when burned, and is a raw material with excellent mechanical forming suitability in the kneading and extrusion punching process, but most are imported from foreign countries, There is a drawback that the cost is high, and the production amount of pyrethrum is decreasing. On the other hand, wood flour and foliage emit smoke when burned,
There are drawbacks of emitting mucosal irritants, off-flavors, and tar components, and these have also been heavily relied on overseas in recent years, and their costs have been increasing. Also, from the standpoint of protecting the natural environment and saving resources, it is desired to reduce the amount of the base material used as described above and to develop another base material instead.

[0005] Conventionally, as an alternative material to the base material of the incense stick, for example, coffee bean shell endothelial powder (JP-B-60-5)
No. 8201) and corn core powder (JP-B 61-61)
No. 11922) have been proposed, but their development points are mainly to suppress generation of smoke, mucous membrane irritation and off-flavor during combustion. On the other hand, JP-A-48-7
No. 2336 proposes to use fine mineral powder as part of the substrate. However, when mineral fine powder is used, if the product hardness is sufficiently increased by blending the usual amount of paste, the flammability of the product obtained with the increase in the blending amount of mineral fine powder is increased. On the other hand, if the compounding amount of the paste is reduced in order to improve the flammability and eliminate the extinction, the strength of the molded product is remarkably reduced, and the molded product becomes impractical.

[0006]

From the viewpoint of resource saving as described above, by increasing the burning time of the base material, even if the weight and the size of the incense are made smaller than the conventional incense stick, the same combustion as in the past can be achieved. It is desired to develop a base material that can secure time. However, in this case, it is necessary to simultaneously satisfy the requirement that the incense stick be burned for a predetermined period of time without burning out and that the volatilization rate of the active ingredient be high. Also, in order to reduce the size and weight of the incense stick,
It is required that the material be excellent in machine formability and that the strength does not change, that is, have a certain level of bending strength, and also that the material be supplied stably and inexpensively as a base material as described above.

JP-A-48-62946 teaches that extracted cake flour of a Dutch sensiti or a sessile plant of the sect. Netherlands is effective in delaying the burning rate of incense. However, these are not always sufficient to satisfy the above conditions, and have problems in cost and stable supply. JP-B-46-28119 discloses another method of delaying the burning rate in which an inorganic layer containing an insecticidal component is attached to the surface of a mosquito coil base material layer. However, in order to sufficiently delay the burning rate, it is necessary to attach a large amount of the inorganic layer to the surface of the base material. In that case, however, there is a problem that the burning may disappear. In addition, after a liquid obtained by kneading an inorganic substance is applied to the surface of a mosquito coil and dried, then a liquid containing an insecticidal component is further dropped and dried. It is difficult to say that it is suitable for industrial production that produces incense in large quantities at low cost.

In general, in order to delay the burning rate of the incense stick, it is necessary to increase the amount of the paste to sufficiently solidify the base material. However, in that case, the burn-off may occur, and the volatilization rate of the active ingredient may decrease. That is, the delay of the burning speed and the extinction of the combustion have an inseparable relationship, and if the burning speed is to be delayed, the extinction of the combustion is likely to occur. On the other hand, sufficient flammability is secured to prevent the extinction. It is necessary. Conventionally, a base material that simultaneously satisfies such conflicting requirements has not been found,
For this reason, the thickness of the conventional mosquito coil has a thickness of 3.5 mm x a width of 6 mm (cross-sectional area of about 21 mm ² , weight of about 14 g). Thus, the burning time could only be adjusted slightly depending on the type of substrate.

Accordingly, an object of the present invention is to increase the burning time without fear of extinguishing at the time of burning, so that even if the weight and the size are reduced, it is possible to secure a smoking time equal to or longer than that of the conventional incense stick. Mosquito coil with excellent volatilization rate of active ingredients,
An object of the present invention is to provide incense sticks such as incense sticks for Buddhist altars. Another object of the present invention is to provide an incense stick using a base material which is excellent in long-term flammability, has little mucous membrane irritation and off-flavor, has good machine moldability, and can be supplied stably and at low cost. It is in.

[0010]

According to the present invention, there is provided an incense stick, characterized in that defatted rice bran is blended as one component of a base material in order to achieve the above object. In burning the incense stick, it is preferable to mix the defatted rice bran at a ratio of 5 to 50% by weight based on the total weight of the incense stick in order to sufficiently delay the burning rate.

[0011]

The present inventors have studied various materials as a base material for incense, and found that defatted rice bran is effective in delaying the burning rate despite the fact that it does not extinguish during burning. In other words, it is possible to maintain the burning state for a long time, without impairing the volatilization rate of the active ingredient at all, and with good machine molding aptitude, no mucosal irritation or off-flavor due to combustion, and reduce the size and weight of the incense stick. The present inventors have found that they are most suitable as a substrate for achieving this, and have completed the present invention. That is, the present invention is characterized by using defatted rice bran as a part of the base material of the incense,
As a result, it is possible to simultaneously satisfy the conflicting demands of delaying the burning rate and preventing extinction, and secure a high volatilization rate of the active ingredient.

The incense stick of the present invention, by incorporating defatted rice bran, can prolong the burning time without burning out during burning, and therefore, it is necessary to secure the same burning time as the conventional incense. And the size can be reduced. As a result, the amount of raw materials used is reduced, costs can be reduced, and resources can be saved.
The amount of smoke and the emission of mucosal irritants are also reduced. In general, when the same base material is used, the burning speed increases as the thickness of the incense becomes thinner.If the cross-sectional area is reduced by half, the length must be doubled to secure the same burning time. The reduction in size does not translate into a reduction in weight. However, in the case of the incense stick of the present invention, by appropriately setting the amount of defatted rice bran to be blended, the burning speed is delayed even if the thickness of the incense stick is reduced, so that the length may be about the same as that of the conventional incense stick. Can be reduced. Further, according to the study of the present inventors, it has been found that by reducing the thickness of the incense stick, the volatilization rate of the active ingredient is improved, and it is difficult to extinguish the active ingredient. Therefore, the volatilization rate of the active ingredient can be further improved by reducing the thickness of the incense stick. As a result, it is possible to mix the active ingredient in a small amount.

The defatted rice bran used in the present invention is obtained by defatting the rice bran produced when brown rice is polished, and the rice bran itself is produced in large quantities in Japan, and is supplied inexpensively and stably. In addition, defatted rice bran is also obtained in large quantities as a by-product during the production of bran oil, and is supplied stably and inexpensively. Rice bran itself has an effect of retarding the burning rate when used as a base material for incense, but in the case of defatted rice bran, the effect is even greater. The compounding amount of the defatted rice bran is 5 to 50% by weight, more preferably 10 to 35% by weight, based on the total weight of the incense stick. If the blending amount of the defatted rice bran is less than 5% by weight, it is difficult to obtain a sufficient effect of delaying the burning rate, which is not preferable. On the other hand, the amount of defatted rice bran is 5
If the content exceeds 0% by weight, particularly incense sticks having a large cross-sectional area are undesirably extinguished. Further, the particle size of the defatted rice bran is desirably 50 mesh pass, more preferably 80 mesh pass, in consideration of suitability for machine molding, surface smoothness of the formed incense, and the like.

Other base materials for the incense include, for example, pyrethrum extract meal powder, wood powder, foliage powder such as cedar and tea, coconut powder, endothelial powder of coffee bean husk, corn core powder, carbon and various other conventionally known materials. A combustion aid can be used. Also,
As the paste, tab powder is mainly used. In addition to tab powder, conventionally known substances such as corn starch, carboxymethylcellulose, dextrin, polyvinyl alcohol, gum arabic, and defatted flaxseed meal can be used.
It is not preferable that the amount of the paste is too large because the paste easily extinguishes during burning.

When the incense stick of the present invention is used as a mosquito coil, various known insecticides can be used as the active insecticide, but from the viewpoint of safety, pyrethroids such as pinamine forte and ethok are used. Insecticides are preferred. The incense stick of the present invention may further contain, in addition to the above-mentioned various components, a dye such as malachite green and a fungicide such as dehydroacetic acid. The incense stick according to the present invention is obtained by kneading the above-mentioned various components with water and shaping it into an appropriate shape. Can be used as In the case of a mosquito coil, the compound is generally produced by kneading the composition with water, extruding the mixture into a sheet, punching it into a spiral, and drying. The active ingredient can be impregnated by spraying, coating, dropping, dipping, or the like after incense molding. According to the present invention, even if the size and weight of the incense stick are reduced, the same burning time as that of the conventional incense stick can be secured, but the size of the incense stick is generally 5 to 50 mm ² , and more preferably 5 to 20 mm ² is desirable. . Incense size is 5m
If it is less than m ^{2 or more} than 50 mm ² , the volatilization rate of the active ingredient is undesirably reduced.

EXAMPLES Hereinafter, the present invention will be described more specifically with reference to Test Examples and Examples, but it is needless to say that the present invention is not limited to the following Examples.

Test Example 1 As shown in Table 1, the amount of defatted rice bran was added to a predetermined amount of pyrethrum extract cake powder, wood flour, and tub flour,
The mixture was kneaded by adding about equal amount of warm water, extruded into a belt shape by an extruder, then punched into a spiral shape by a punching machine, and dried by air drying to obtain a test incense stick (3.5 m thick).
m, width 6 mm). Various characteristics of the incense stick were measured. The results are shown in Table 1.

[Table 1] As is evident from the results shown in Table 1, the incense in which defatted rice bran was blended according to the present invention increased the burning time per volume as the amount of defatted rice bran increased in comparison with the incense without defatted rice bran. It became long and did not go out. Further, almost no off-flavor was generated during the combustion, and the moldability and the drying property were also good. In addition, by adding defatted rice bran, it was possible to greatly reduce the amount of expensive pyrethrum extract extracted meal powder.

Test Example 2 As shown in Table 2, the amount of defatted rice bran was added to a predetermined amount of pyrethrum extract meal powder, wood flour, tea flour, and tub flour at varying amounts, mixed, and mixed in approximately equal amounts. The mixture was kneaded with hot water, extruded into an extruder, extruded into rods having a cross-sectional area of Xmm ² of various sizes, cut into a predetermined length, and dried by air drying to obtain a test incense stick. In this case, pinamine forte was used as an active ingredient. About this incense stick, the burning rate and the volatilization rate were measured. The results are also shown in Table 2. The volatilization rate was determined by collecting smoke with a funnel-shaped suction device, absorbing the smoke into silica gel, extracting with a solvent, and then performing gas chromatography.

[Table 2]

As is evident from the results shown in Table 2, the incense containing the defatted rice bran of the present invention (Examples Nos. 5 to 9) is the same as the conventional incense containing no defatted rice bran (Example No. 12). In comparison, the burning rate was delayed, and the effect became more significant as the blended amount of defatted rice bran was increased, and even when the blended amount was increased, burning did not occur. On the other hand, incense sticks (Example No. 10, 1
In 1), although the effect of retarding the burning rate is recognized, the extinction occurs, especially when the amount of the starch increases and the thickness of the incense increases so as to approach the normal size (20 mm ² ). It turns out that it becomes easy. In addition, as is clear from Table 2, when the burning speed of the conventional incense stick (the cross-sectional area of Example No. 12 X: 20 mm ² ) is 50 minutes / 10 cm, the Example No. No. 6 having a cross-sectional area of 15 mm ² ,
No. 7 with a cross-sectional area of 10 mm ² , 8 is comparable to the burning rate of 5 mm ² , which means that the diameter of the incense can be reduced and / or the length of the incense can be shortened in order to achieve the same burning rate as a conventional incense. This means that usage can be reduced. The incense stick of the present invention containing defatted rice bran showed a volatilization rate of the active ingredient which was equal to or higher than that of a commercially available mosquito coil. Also,
Although the volatilization rate of the active ingredient does not decrease so much even if the blending amount of the defatted rice bran is increased, the volatilization rate of the active ingredient decreases in the incense blended with starch, and it can be seen that the volatility decreases particularly as the blending amount of the starch increases. . Furthermore, incense sticks having various cross-sectional areas having a cross-sectional area of 20 mm ² or more other than those shown in Table 2 were formed, and the burning rate was measured for those incense sticks. as a result,
For incense with 15% by weight of defatted rice bran, cross section 30m
In the case of m ² , 72 minutes / 10 cm (no blending: 56 minutes / 10 c
m), 78 minutes / 10 cm for a cross section of 40 mm ² (no blending: 65 min / 10 cm), 83 for a cross section of 50 mm ²
The burning rate was slowed down to 10 minutes / min (no blending: 71 minutes / 10 cm). However, as compared with a cross-sectional area of 20 mm ² or less, the delay ratio tended to decrease as the cross-sectional area increased. If the cross-sectional area exceeds 50 mm ² , the burn-out will occur during combustion, which is not preferable.

Test Example 3 As shown in Table 3, varying amounts of defatted rice bran were added to predetermined amounts of wood flour, charcoal flour, and tub flour, mixed, and approximately equal amounts of warm water were added. The mixture was extruded into rods having a cross section of Xmm ² of various sizes through an extruder, cut into a predetermined length, and dried by air drying to obtain a test incense stick. In addition,
At this time, a floral-based compounded fragrance was also used. The burning rate of the incense was measured. The results are shown in Table 3.

[Table 3] As is evident from the results shown in Table 3, the incense containing the defatted rice bran of the present invention (Examples Nos. 13 to 16) also contains defatted rice bran, even for a combustion base material using a coal powder having a high burning rate. The burning rate was delayed as compared with the incense stick (Example No. 17) which was not provided, and the effect became more remarkable as the blended amount of defatted rice bran was increased, and even when the blended amount was increased, burn-out did not occur during burning.

Test Example 4 As shown in Table 4, rice bran (oil bran before defatting) or defatted rice bran was added to a predetermined amount of pyrethrum extract meal powder, wood flour, and tub flour, and mixed. Then, add about equal amount of water and knead it, extrude it into an extruder and extrude it into rods of various diameters,
Cut to length. This was dried by air drying to obtain a test incense stick. The burning rate of this incense was measured. Table 5 shows the results.

[Table 4]

[0022]

[Table 5] From the results shown in Table 5, it can be seen that although the rice bran has an effect of delaying the burning time, the effect of defatted rice bran is remarkable.

Example 1 A incense stick having a cross-sectional area of about 13 mm ² and a burning time (about 7 hours / roll) having substantially the same burning time as that of a commercially available mosquito coil can be obtained by removing pyrethrum extract wood powder, wood powder, tea powder, and tub. Combustion base material with defatted rice bran mixed with flour and pinamine forte and other malachite green,
A predetermined amount of an antifungal agent and the like are added and mixed, kneaded by adding about an equal amount of warm water, extruded into a belt shape by an extruder, then punched into a spiral by a punching machine, and dried by air drying. Manufacturing,
This was used as a test incense stick (the amount of pinamine forte used at this time was the same as that of a commercially available incense stick (0.3%) / 1 volume). When one incense stick (6.3 g) was used in a room of 6 tatami mats, it smoked for a burning time of 7 hours, and mosquitoes could be completely controlled. When the volatilization rate of the active ingredient was measured for this incense stick, the commercial incense stick A was 64% and the commercial incense stick B68% was 6%.
It was equal to or higher than 8% although the burning rate was delayed.

Example 2 An incense stick having a cross-sectional area of about 7 mm ² and having substantially the same burning time and volatilization rate as a commercially available mosquito coil can be obtained by adding defatted rice bran to pyrethrum extract meal powder, wood powder, tea powder, and tub powder. A predetermined amount of the blended combustion base material and pinamine forte, other malachite green, an antifungal agent, etc. are added and mixed, and about an equal amount of warm water is added and kneaded, and the mixture is extruded into a belt shape by an extruder, and then punched. It was punched into a spiral by a punching machine and dried by air drying to produce a test incense stick. The amount of raw material used for one incense stick was examined. As a result, it was possible to manufacture the incense stick with 49% less raw material as compared with a commercially available incense stick, thereby reducing costs and saving resources.

Example 3 An incense stick having a cross-sectional area of about 10 mm ² having an outer diameter approximately the same as that of a commercially available mosquito coil (about 12 cm) was mixed with defatted chrysanthemum extract cake powder, coconut powder, and tub powder with defatted rice bran. Add a predetermined amount of a combustion base material, ethok, other malachite green, fungicide, etc., mix, add about equal amount of warm water, knead, extrude this into a belt shape with an extruder, and then spirally shape with a punching machine. And dried by air drying to produce a test incense stick. When one roll of this incense stick (about 12 g) was used outdoors in a kennel, there was no mosquito bite for a very long time of 10 hours compared to about 6 hours for burning a commercial incense stick.

Example 4 The diameter (2 mm) and length (1
4cm) incense, cedar leaf powder, birch bark powder, tub powder, tea powder, and a combustion base in which defatted rice bran is blended with a predetermined amount of a fragrance, other pigments, fungicides, etc. The mixture was kneaded with hot water, extruded into a rod by an extruder, and dried by air drying to produce a test incense stick.
When this incense stick was burned between Buddhas of 8 tatami mats, the burning time of the commercial incense stick was about 40 minutes, and for a long time of 65 minutes, there was no nasty smell and a faint fragrance was flowing.

[0027]

As described above, the incense according to the present invention can have a longer burning time without burning out by burning defatted rice bran as a component of the base material. Weight and size can be reduced to ensure the same burning time as incense sticks. as a result,
The amount of raw materials used can be reduced, cost can be reduced, resources can be saved, and the amount of smoke and the emission of mucosal irritants can be reduced. Further, by reducing the thickness of the incense stick, an effect of further improving the volatilization rate of the active ingredient is obtained, and as a result, the advantage that the amount of the active ingredient can be reduced can be obtained. In addition, the defatted rice bran used in the present invention can be obtained in large quantities and inexpensively in Japan, and because it is an imported product, it is possible to reduce the compounding amount of pyrethrum extract cake powder and the like, which is expensive and may be supplied in the future, and the supply amount is concerned about. The advantages in practical use are extremely large, such as the cost can be considerably reduced and there is no fear of supply instability.
