Description

The present invention relates to an improvement of a spiral incense.

Spiral scents such as mosquito coils are mainly used to control adult mosquitoes, and have long been loved as an indispensable part of summer in ordinary households. The mosquito coil was devised in 1890, and at that time the rod was about 30cm long and the burning time was about 1 hour, but after that the shape of the mosquito coil was changed from a rod to a spiral. Also, the burning time for one bottle was about 7 to 8 hours according to the human bedtime. Swirl incense is convenient because it can be easily used anywhere in a match, maintains a certain insecticidal effect until it burns out, and excels in the diffusion of active ingredients. It can be said that the insecticidal form.
Spiral incense is a mixed powder containing active ingredients, binder, extender such as vegetable powder, kneaded with dye, antifungal agent and water, then put into a plate-like sheet through an extruder and spiraled by a punching machine. Generally, it is punched and dried to a moisture content of about 7 to 10%. Green swirl incense using malachite green as a dye is the mainstream.

By the way, some proposals for applying a pattern or design to the surface of an incense stick have been known. For example, a method of printing on a stick-shaped incense stick using a roller (Japanese Patent Laid-Open No. 51-151344) and a stick-shaped incense stick with characters or pictures printed on the surface (Japanese Utility Model Laid-Open No. 7-38137) are disclosed. These are all related to rod-shaped incense that lacks technical specificity and cannot be applied to spiral incense. In addition, these publications have no description about the generation of harmful components due to combustion, and have not been any reference in creating a spiral incense that maintains conventional safety and takes into consideration design.
Japanese Patent Laid-Open No. 51-151344 Japanese Utility Model Publication No. 7-38137

An object of the present invention is to provide a spiral incense that not only retains the insecticidal efficacy, safety, quality, and the like of a conventional spiral incense but also takes into account design.

In order to solve the above problems, the present invention adopts the following configuration.
( 1 ) A spiral incense that has a edible colorant that does not generate harmful components during combustion and that does not contain heavy metals, and is printed on the surface using ink containing the colorant .

The spiral incense according to the present invention has not only the insecticidal efficacy, safety and quality of the conventional spiral incense, but also has design, so that its practicality is extremely high.

As the spiral incense to which printing is applied in the present invention, in addition to a general mosquito coil, an incense for fly, an incense for harmful insects may be used, and the color of the incense is not particularly limited, and as a dye Various examples include a green one using malachite green, a yellow one not using a dye, and a black one containing elementary ash as a base material.

What is necessary is just to select a conventionally well-known thing suitably as a raw material and a base material used for manufacture of the spiral incense of this invention.
The active ingredient is preferably a pyrethroid insecticide from the viewpoint of insecticidal efficacy and safety, and includes natural insecticidal chrysanthemum powder, allethrin, flamethrin, praretrin, empentrin, transfluthrin, metfurthrin and the like. In the case of synthetic pyrethroids, when there are optical isomers or geometric isomers based on asymmetric carbon or double bonds in the chemical structure, it is a matter of course to include each alone or in any mixture. In addition, in order to enhance the insecticidal efficacy, a synergist such as piperonyl butoxide, MGK-264, and cinepirin 500 can be added.
Examples of the binder include starch, tab powder, carboxymethylcellulose, etc., and examples of the bulking agent include pesticide chrysanthemum extract powder, fir, toga, hinoki, tea, citrus and other plant powders, diatomaceous earth, clay, kaolin, Examples thereof include mineral powder such as talc, and raw ash.
Further, as a dye blended in the spiral incense itself, green dyes such as malachite green and mosquito green are representative, and as an antifungal agent, ethyl rhodanacetate, potassium sorbate, sodium dehydroacetate and the like are used.

The spiral incense of the present invention is a pigment that does not generate harmful components during combustion and does not contain heavy metals after kneading the mixture containing the raw material and water, punching into a spiral shape, drying to a moisture content of about 7 to 10% It is characterized by printing on the surface using an ink formulated with.
Here, the pigment that does not generate harmful components during combustion and does not contain heavy metals is preferably a food pigment, but is not limited thereto as long as it meets the object of the present invention. Examples of food dyes include red for food red No. 3 (erythrosine), food red No. 40, gardenia red pigment, safflower red pigment, paprika pigment, yellow for food yellow No. 5, gardenia yellow, and indigo for food blue No. (Brilliant Blue), Indigo, etc., and these dyes have almost no concern of generating harmful components during combustion.
On the other hand, synthetic pigments commonly used in pad printing and silk screen printing, such as red alizarin lake, yellow azo, and indigo phthalocyanine, are safe when they are applied to swirl incense, although they generate trace amounts of harmful components during combustion. It was recognized that this was not preferable. When the synthetic pigment is burned at a high temperature, no particular problem is caused. Therefore, the phenomenon is considered to occur due to the fact that the spiral incense is slow burning and the temperature of the burning part is 700 to 800 ° C. It is done.
In addition, when a pigment containing heavy metal is used, even if no harmful components are generated during combustion, harmful heavy metals may remain in the ash after combustion, which does not meet the object of the present invention.

The ink used for printing is prepared by mixing the pigment with a medium, a solvent, and the like, and the one containing edible ink is called “edible ink”.
The blending amount of the dye is preferably set to 30% by weight or more in order to improve the concealing property since the color of the spiral scented base is easy to see through. The medium and the solvent may be appropriately selected from conventionally known ones.
In printing, if necessary, a solvent for dilution may be added. However, the amount added should be suppressed as much as possible so as not to cause a decrease in concealing property and uneven printing.

In the present invention, pad printing, silk screen printing, ink jet printing, or the like can be adopted as a printing method. However, pad printing or silk screen printing is more preferable because of the particularity that the printing substrate is easily stained. In the case of inkjet printing, there is a merit that multi-color printing can be performed, but since the viscosity and concealment property of the ink are lower than the former, the jetting time is lengthened or the substrate surface is coated with medium. Ingenuity is required.
In pad printing or silk screen printing, in order to prevent deterioration of concealability and uneven printing, the plate depth is maximized, the powder on the spiral incense stick surface is removed before printing, and the pad or A measure such as washing the silk mesh of the screen is taken. If the printing density is insufficient, it is sufficient to increase the amount of ink by multiple printing at the same place.
In the case of silk screen printing, since the pressure applied to the printing substrate is larger than that of pad printing, it is preferable to place the spiral incense on a relatively soft plate such as urethane or silicon.

The spiral incense with the design and characters printed in this way retains the insecticidal efficacy, safety and quality of conventional spiral incense, and also has design, so you can enjoy the sense of fun while enjoying mosquitoes, flies and other pests. It is useful for extermination.

Next, based on a specific embodiment, the spiral incense of the present invention will be described in more detail.

dl, d-T80-alleslin 0.3 parts, α-starch and tab powder binder 18 parts and wood powder 81 parts mixed powder malachite green 0.2 parts After adding 0.1 part of potassium sorbate as a glaze and 100 parts of water and kneading, it is extruded to form a plate-like sheet, punched into a spiral shape by a punching machine, dried to a moisture content of about 7 to 10%, and then green A spiral incense stick (1) was produced.
On the other hand, as a pad printing ink, a composition containing 40% by weight of a gardenia pigment which is a yellow food pigment, medium and a propylene glycol solvent was prepared. A plate with a pattern imitating an animal elephant was prepared, and the elephant pattern (2) was pad-printed on the spiral incense stick (1) from which the powder on the surface was removed using the ink. During printing, part of the surface base material of the spiral incense stick (1) might adhere to the pad and mix with ink, so printing was interrupted and the pad was washed.

The spiral incense stick (1) of the present invention thus obtained was used while sleeping in a 6 tatami room. I enjoyed the design before ignition, and I was not bothered by mosquitoes while sleeping. Moreover, since there was no possibility of generating harmful components, it could be used with confidence.

Various spiral scents were prepared according to Example 1, and the performance was evaluated for the following items. The results are shown in Table 1.
(1) Insecticidal efficacy: The insecticidal efficacy of the target pests was examined and evaluated by ○, Δ, ×.
(2) Designability: Whether or not it has designability was evaluated by ○, Δ, ×.
(3) Safety: From the viewpoint of the generation of harmful components, evaluation was made by ○, Δ, ×.

As a result of the test, it was confirmed that the spiral incense of the present invention was excellent in insecticidal efficacy, design and safety, and extremely practical. In addition, since the color of the incense base material is easy to see through, the prescription of the ink is more preferable that the amount of the pigment is increased to 30% or more.
On the other hand, the conventional spiral incense stick (Comparative Example 1) is inferior in design, and as in Comparative Example 2, the incense stick produced using a synthetic pigment such as alizarin lake generates a toxic component in a small amount during combustion. It was not preferable in terms of safety. In addition, even if it is a synthetic pigment, since it is not a slow burning incense incense stick form and does not produce a problem in particular when it is burned at a high temperature, the knowledge of the present invention is a novel obtained only after testing a spiral incense. Is.

The spiral incense of the present invention is highly practical as an insecticide, and can be applied to other incense sticks such as Buddhist altars.

The top view of an example of the spiral incense of this invention is shown.
