Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to smoking devices and methods, and more particularly to devices and methods for smoking a smoking agent.

[0002]

BACKGROUND OF THE INVENTION Smoke agents are agents that smoke pesticides by heating. Conventionally, as one method of heating a smoking agent to smoke it, a smoking agent containing a self-combustible substance such as nitrocellulose is used to generate heat of a reaction between a metal oxide and silicon (so-called thermite reaction). However, a direct heating method is known in which the smoke agent itself is self-combusted by directly heating (igniting) all at once. Regarding the heating method by the thermite reaction, see JP-Sho 62-14642.
No. 7 and JP-A-1-288218.

However, since the heating method by the thermite reaction is a combustion reaction, the temperature becomes unnecessarily high at the time of heating, so that the active ingredient in the smoke agent may cause thermal decomposition, and thus the thermal decomposition property is high. There is a problem in using a drug having a high concentration as an active ingredient. On the other hand, a smoke agent containing a so-called organic foaming agent, which generally does not have self-combustibility, is used for a relatively long time indirectly from the outside due to the high heat generated by the hydration reaction of a large amount of calcium oxide and water. There is also an indirect heating method that gently heats for an hour (Japanese Patent Publication No. 59-4920).
No. 1).

In the above indirect heating method, the calorific value per weight of calcium oxide is low in the case of the hydration reaction using calcium oxide. Therefore, in order to effectively volatilize the insecticidal component, it is necessary to use more than the weight of the smoke agent. Much more weight of calcium oxide was needed. Furthermore, in the indirect heating method, even if a large amount of calcium oxide was used, the exothermic rate (hydration reaction rate) after adding water was slow, and it took a considerable amount of time to start smoking.

Japanese Utility Model Publication No. 5-6922 discloses that quicklime is tableted and formed into a ring shape or a cylindrical shape and used as a heating element for heating canned food. However, the heating element for heating is merely intended to be easily filled in a container, to prevent the exothermic agent from splashing, and to uniformly heat the canned food, and to start smoking the smoking agent. It is not enough to obtain the required amount of heat in a short time after adding water.

[0006]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a device that causes less thermal decomposition of an active ingredient, efficiently heats a smoking agent, and quickly starts smoking. The purpose is to provide a method.

[0007]

Means for Solving the Problems The inventors of the present invention have conducted extensive studies to solve the above problems, and have developed an apparatus for heating a smoking agent utilizing high heat generated by the hydration reaction of calcium oxide. The present invention has been completed by discovering that, when the smoker is designed and the smoker is heated by using this device, the smoker of the smoker can be started efficiently and quickly.

That is, the present invention relates to a device for smoking a fumigant, comprising: i) a first container containing water; ii) a heating agent containing calcium oxide. A device as described above, characterized in that it comprises two containers, iii) a third container containing a smoking agent, and iv) means for facilitating the opening of the first and second containers. In the apparatus of the present invention, since the first container in which water is sealed is prepared in advance, it is possible for the user to avoid the trouble of fetching water necessary for the hydration reaction of calcium oxide.

In the device of the present invention, the first container and the second container
The container is installed separately, and the second container is the third
It is recommended to be installed inside the container. By installing the first container and the second container separately, even if these containers are damaged during transportation of the device, calcium oxide which is an active ingredient of the exothermic agent reacts with water to generate heat, As a result, it is possible to avoid the situation where the smoke agent is heated and smoke is generated. For example, the first container may be installed below the bottom surface of the third container. In addition, by installing the second container inside the third container, it is possible to reduce the size and weight of the smoking device.

Further, in the apparatus of the present invention, the third container has a double container structure having an inner container and an outer container, and the smoking agent is stored in the inner container and the third container is The space between the outer container and the outer container may form a heat insulating layer. By forming the heat insulating layer, the heat generated during smoking can be absorbed and the device can be cooled from the side surface, and the temperature rise of the entire device can be suppressed. Further, the third container may have a raised bottom structure. By taking the structure of the raised bottom, the device can be cooled from the bottom surface and the temperature rise of the entire device can be suppressed. Further, the third container needs to have a plume hole. The fumes are preferably provided on the ceiling surface of the third container. The presence of the fumes facilitates the release of the active ingredient (for example, an insecticide, a bactericide, or a mixture thereof) in the smoke agent to the outside during smoking. However, before using the smoking device, prevent the smoking agent from scattering from the fumes,
In order to prevent decomposition and alteration of the smoke agent components due to moisture and other substances present in the atmosphere, it is preferable that the fumes be blocked with a film or the like. Then, it is convenient that the film is melted and the fumes are exposed when the smoke device is heated so that the active ingredient in the fumigant can be discharged from the fumes.
This film is preferably a heat-meltable film.

The material of the first container is polyethylene,
Examples thereof include cellophane, aluminum, polypropylene and the like and composite materials thereof. Calcium oxide in the exothermic agent preferably has an exothermic rate of 5 ° C./sec or more when 20 g of the calcium oxide is reacted with 6 mL of water. In the present specification, the "heat generation rate" means from the start time of heat generation due to the hydration reaction of calcium oxide and water to the maximum temperature arrival time,
The average temperature rise per second is shown. Heat generation rate is 25 ℃
Or at room temperature, put 20 g of calcium oxide powder or granules in a glass tube, hydrate it with 6 ml of water, measure the internal maximum temperature with a CA thermocouple placed in the center of calcium oxide, and start the hydration reaction. It can be determined by obtaining the average temperature rise per second until the maximum temperature is reached. The heat generation rate of conventional calcium oxide used for heating smoking agents is 20 g of calcium oxide
When reacted with ml, it is about 3 ° C / sec or less. on the other hand,
The heat generation rate of calcium oxide used in the present invention is 5 ° C./sec or more, preferably 6 ° C./sec or more, when 20 g of calcium oxide is reacted with 6 ml of water. The calcium oxide used in the present invention, which has an exothermic rate of 5 ° C./sec or more when 20 g of calcium oxide is reacted with 6 ml of water, is
It will be referred to as "highly active calcium oxide".

Further, the exothermic agent is molded, and as a result, the maximum temperature reached on the surface of the exothermic agent is caused by the heat generated when the calcium oxide in the exothermic agent reacts with water. It should be above. The maximum surface temperature of the exothermic agent is preferably 200 ° C. or higher. For example, the exothermic agent is preferably molded at a tableting pressure of 100 to 400 kg / cm ² , and the porosity (%) of the molded exothermic agent is 30 to 60.
%, And the hardness is preferably 2 to 20 kgf. In a preferred embodiment, the exothermic agent is molded into the shape of a perforated molded body. In the present specification, "perforated molded article"
The term "cylindrical, cubical, rectangular parallelepiped, polygonal columnar, polygonal, spherical or other shaped article having one or two or more holes" means that the holes penetrate the article. Good
It does not have to penetrate. When the hole does not penetrate, the depth of the hole is preferably 1/3 or more of the thickness of the molded body. Examples of such a perforated molded body include a cylindrical, ring-shaped, and cup-shaped molded body. Further, instead of the perforated molded body, a calcium oxide unit is obtained by tableting by molding a highly active calcium oxide into a groove on the surface of the molded body or forming the molded body into a star shape or the like. A molded product having a surface area per weight that is similar to that of the perforated molded product can also obtain the same effect as that of the perforated molded product of the present invention. By molding the exothermic agent, especially tableting, the apparent specific gravity becomes high, and it is possible to design the form of the smoke device with a smaller amount of heating space than before, and it has become smaller and lighter than before. A smoking device can be designed.

The weight ratio of water sealed in the first container to calcium oxide contained in the exothermic agent sealed in the second container is preferably 1: 1 to 1: 6. It is also preferable to react 100% by weight or less of calcium oxide with water based on the total weight of the smoking agent to be heated. The second container is preferably made of a heat conductive material. The thermally conductive material preferably has a thermal conductivity (at 25 ° C.) of 5 W / m · ° C. or higher, more preferably 10 W / m · ° C. or higher. Thermally conductive materials can include aluminum, tinplate, copper, and iron. By manufacturing the second container with a heat conductive material, the thermal efficiency can be improved, and as a result, the smoking device can be reduced in size and weight.

Examples of the drug that can be used as the smoke agent include various drugs such as insecticides and bactericides and their mixtures depending on the purpose. Examples of the insecticide include pyrethroids such as permethrin, allethrin, resmethrin, cyphenothrin, plaethrin, phenothrin, fenvalerate, fenpropatrine, etofenprox, fenitrothion, dichlorvos (DDVP), diazinon, prothiophos, and bait. Organophosphorus drugs such as Tex, and carbamate drugs such as propoxur and methoxadiazone can be used.

As the above-mentioned bactericides, bactericides for agricultural chemicals such as isophthalonitrile, procymidone, bayletone and morestan, siabendazole, 3-iodo-2-propynyl butyl carbamate (IPBC), IF-1000 and the like for environmental hygiene A germicide or the like can be used. The content of the above-mentioned agents is 1% by weight or more and 30% or more based on the total weight of the smoking agent.
It is preferably not more than wt%.

The smoke agent contains a combustion base. Examples of the combustion base include nitrocellulose, azodicarbonamide, dinitrosopentamethylenetetramine, oxybisbenzenesulfonyl hydrazide, nitroguanidine, potassium chlorate and ammonium nitrate. Examples thereof include a composition comprising an oxidizing agent such as the above and a combustible substance such as sugar and wood flour.

Smoke agents are, in addition to the above-mentioned agents and combustion bases,
An exothermic aid such as melamine and zinc oxide, and an inorganic mineral substance such as clay, kaolin, talc and diatomaceous earth may be contained. Furthermore, binders and fragrances such as carboxymethyl cellulose, hydroxypropyl methyl cellulose, polyvinyl alcohol and starch, piperonyl butoxide, S
Additives such as efficacy enhancers such as -421 and antioxidants such as BHT and tocopherol may be contained. In a preferred embodiment, the smoke agent comprises a combustion base consisting of a composition consisting of nitrocellulose, azodicarbonamide, dinitrosopentamethylenetetramine, oxybisbenzenesulfonyl hydrazide, nitroguanidine, an oxidizing agent, and a flammable substance. . As the dosage form of the smoke agent,
Powders, granules, tablets, pastes and the like can be mentioned.

The weight ratio of calcium oxide in the exothermic agent enclosed in the second container to the combustion base in the smoking agent contained in the third container is preferably 4:50 to 50:50. .
Examples of the material of the third container include paper, aluminum, polyethylene and the like. The inside of the third container may be coated so as to prevent or reduce the infiltration of the ingredients in the smoking agent into the third container. For example, the inside of the third container can be coated with a material such as aluminum or polyethylene.

The second container preferably has a hole on the bottom surface. By providing holes on the bottom surface, it is possible to prevent the internal pressure of the second container from rising due to the water vapor generated by the hydration reaction of calcium oxide, and to prevent the scattering of boiling water containing calcium hydroxide produced by this hydration reaction. can do. Hole diameter (φ)
Is preferably 3 to 10 mm. When the second container having a hole on the bottom surface is adopted, it becomes necessary to provide the smoke device body with a water vapor barrier property. This is because calcium oxide easily absorbs moisture. As one of the means for solving the problem, it is possible to install the second container inside the third container and further design such that these containers are housed in an outer container in a state of being wrapped in a bag. In this case, the first container may be installed separately from the bag, and the means for facilitating the opening of the first container and the second container may be installed separately from the first container and the bag. I hope you are there. The bag preferably has a water vapor barrier property, for example, an aluminum bag. Preferably, the bag is made of a resin-laminated aluminum film. By laminating the aluminum film with the resin, heat sealability is imparted, and the bag can be easily sealed by heat.

The present invention uses a means for facilitating the opening of a container to open a first container containing water and a second container containing an exothermic agent containing calcium oxide. To bring the water enclosed in the first container into contact with the exothermic agent in the second container to react the calcium oxide in the exothermic agent with water, and heat the smoking agent by the heat generated in the reaction. Also provided is a method of smoking a smoking agent, characterized by:
