2. Description of the Related Art Smoke agents have been used for controlling and controlling pests and mites, such as cockroaches, bed bugs, lice, house dust mites and house dust mites, which live in the home. Smoke smoking agents correspond to high-concentration space treatment agents for a short period of time, and have the advantage of being able to process large spaces without hassle, but require sufficient considerations such as efficacy, safety against human body, and safety against fire. There are two types of smokers currently on the market, one for combustibles and oxygen-releasing substances, such as nitrates,
It contains chromate, perchlorate, etc., and burns at an appropriate speed from the ignited position, and the substance to be volatilized in the burning part volatilizes in the air. The other is prepared by adding an insecticidal component, an organic foaming agent, and, if necessary, a bulking agent (organic or inorganic substance). The insecticidal component is produced by utilizing the power of gas generated during the thermal decomposition of the organic foaming agent. Is to evaporate. A typical example of the organic blowing agent is azodicarbonamide, which has a low odor and a large gas amount. On the other hand, smoking methods have also been diversified in connection with the contents of the smoking agent, and various methods such as heating by adding water to calcium oxide, electric heaters, and the like have been disclosed and put into practical use from conventional ignition by matching. , These methods have the advantage of not using fire, but in order to prevent danger in stock and prevent breakage, the packaging and containers must be strong and airtight,
High costs are required, such as using double plastic containers or metal aluminum cans. Further, in the method of adding water to calcium oxide, there is also a problem that if the amount of water to be added is wrong, smoking does not start.

The present inventors have previously disclosed in Japanese Patent Application Laid-Open No. 58-1830.
No. 1 (Japanese Patent Publication No. 1-57081), the igniter is brought into contact with a smoke agent formed by bagging a smoke agent composition containing an insecticide and an organic foaming agent having a decomposition temperature of 250 ° C. or less. Then, the organic foaming agent is thermally decomposed, and a pesticidal component is erupted from the contact portion. Further, JP-A-63-267705 discloses
JP-A-64-42401 discloses a method disclosed in
As an improvement of the technology described in Japanese Patent No. 18301, a smoking agent composition containing permethrin, an antioxidant, and an organic foaming agent is applied only to the contacted portion of an igniter made of a mildly combustible material when the igniter is contacted. A smoking agent characterized by being packed in a synthetic resin film having a hole, preferably a synthetic resin film having a melting point of 90 to 120 ° C., and a smoking method using the same are disclosed. Although these smoking agents and the smoking method provided a system for easily and efficiently smoking insecticidal components, the use of slow-burning materials such as incense sticks as igniters meant that they could be used. There was room for improvement.

[0004]

DISCLOSURE OF THE INVENTION The present invention relates to an igniter capable of securely and efficiently smoking compared to a conventional smoking method, and more specifically, an organic igniter excellent in usability and safety. An object of the present invention is to provide a smoker igniter that can be efficiently applied to a smoker obtained by enclosing a smoker composition containing azodicarbonamide as a foaming agent in a synthetic resin film bag.

[0005]

Means for Solving the Problems In order to solve the above-mentioned problems, the present inventors have made intensive studies and as a result, put a bar-shaped exothermic agent which does not belong to explosives into a heating agent storage tube, It is recognized that an igniter to which an explosive such as a match head medicine is attached is extremely useful. Further, this igniter and an azo containing one or two selected from zinc oxide and zinc carbonate as a foaming aid are added. The present inventor has found that a very efficient and practical smoke system can be provided by combining a smoke agent composition containing a dicarbonamide blowing agent with a smoke agent sealed in a synthetic resin film bag. Completed the invention.

That is, according to the first aspect of the present invention, there is provided a igniter for a smoking agent in which a rod-shaped exothermic agent not belonging to explosives is placed in an exothermic agent storage tube, and an explosive such as a match head medicine is attached to the tip of the rod-shaped exothermic agent. According to.

A feature of the igniter of the present invention is that a rod-shaped exothermic agent which does not belong to explosives is placed in a heating agent accommodating tube, and an explosive such as a match head medicine is attached to the tip of the rod-shaped exothermic agent. As an example of using a heating agent as an igniter, Japanese Patent Application Laid-Open No. 6-7065 discloses a device such as an incense stick, a squib, a heating wire, or the like.
A device capable of maintaining a temperature of not less than ° C. for a predetermined time is disclosed. However, although there is a description that decomposition is used for a self-propagating smoker, there is no mention of a combination with a smoker, such as the type and amount of a foaming agent or a foaming aid. The present inventors have found that a rod-shaped exothermic agent that does not belong to explosives is placed in an exothermic agent storage tube, and that an explosive such as a match head medicine is attached is particularly effective as a smoker igniter. Preferably, a smoking agent composition using an azodicarbonamide foaming agent containing one or two selected from zinc oxide and zinc carbonate as a foaming aid, that is, a smoking agent described later, that is, a synthetic resin is used. Combining this with the one enclosed in a film bag makes it possible to start and continue the plume smoothly.

The exothermic rods used in the present invention include:
Examples include a firing rod made of silicon iron and a metal oxide, and an ignition agent for charcoal. Japanese Patent Application Laid-Open No. HEI 9-175907 discloses a smoke igniter in which a heating agent is filled in a heating agent storage container and a match head medicine is attached thereto. The exothermic agent is used, and a gap is easily generated between the match head medicine and the exothermic agent due to vibration or the like. Therefore, since it is necessary to densely fill the heat generating agent into the storage container, a fume hole for discharging the combustion gas is provided in the heat generating agent storage container in order to prevent an increase in the internal pressure due to the combustion gas generated when the heat generating agent is burned. I had to. In the igniter of the present invention, a gap is generated between the exothermic agent and the exothermic agent storage tube to insert the rod-shaped exothermic agent into the exothermic agent storage tube,
The internal pressure does not increase, and there is no need to provide a fumarole. Further, since the match head medicine is directly attached to the rod-shaped heating agent, there is no fear that a gap is formed between the heat generation agent and the match head medicine. As the shape of the exothermic agent storage tube used in the present invention, a cylindrical or prismatic shape into which a rod-shaped exothermic agent can be easily inserted is preferable. The material is preferably made of metal in order to efficiently transmit the amount of heat generated from the exothermic agent to the smoking agent, and examples of the metal include iron, aluminum, brass, and copper. The thickness is preferably 0.3 mm or less, and particularly preferably 0.1 mm to 0.2 mm. The rod-shaped exothermic agent may be stored in the exothermic agent storage tube, and then an explosive, such as a match head medicine, may be attached thereto, or the exothermic agent may be attached first, and then stored in the exothermic agent storage tube. In addition, when the rod-shaped exothermic agent is placed in the exothermic agent storage tube and an ignition agent such as a match head medicine is attached, the opening of the exothermic agent storage tube must be turned downward, and the rod-shaped exothermic agent is not fixed at that time. When,
There is a risk that the bar-shaped exothermic agent may fall off or shift.
For this reason, it is preferable to fix the bar-shaped exothermic agent to the exothermic agent storage tube. As a fixing method, a method of caulking a part of the exothermic agent storage tube, a method of using an adhesive or a pressure-sensitive adhesive, and a combination of an adhesive with a igniting agent There is a method, a method of filling the gap between the exothermic agent and the storage tube, a method of using other fixing tools, and the like. Of these, the method of caulking a part of the exothermic agent storage tube is practical, and the method of caulking the opening end is particularly preferable because it can be fixed easily and securely.

According to a second aspect of the present invention, a firing rod made of silicon iron and a metal oxide is used as a bar-shaped exothermic agent, and a metal tube having a thickness of 0.3 mm or less is used as an exothermic agent storage tube.

According to a third aspect of the present invention, the bar-shaped exothermic agent is fixed by caulking an open end of the exothermic agent storage tube in which the bar-shaped exothermic agent is stored. By adopting such a method, the explosive can be deposited economically and efficiently without extra cost and without the rod-shaped exothermic agent falling off or shifting. In addition, even when an explosive such as a match head medicine is attached to the rod-shaped exothermic agent and then put into the exothermic agent storage tube, the rod-shaped exothermic agent with the explosive and the exothermic agent storage tube may be connected to another fixing device, adhesive, or the like. It is possible to simply and efficiently fix without using. There is no particular limitation on the method of caulking the opening end of the exothermic agent storage tube, but it is preferable to caulk three or more places at equal intervals in order to uniformly apply a pyrotechnic such as a match head medicine.

[0011] The invention according to claim 4 is characterized in that one or two kinds selected from pyrethroid insecticides and carbamate insecticides, azodicarbonamide, and one or two kinds selected from zinc oxide and zinc carbonate. The smoke agent obtained by enclosing the smoke agent composition containing the resin in a synthetic resin film bag is brought into contact with a heating agent storage tube, and the heat is generated to form an injection hole in the film bag, thereby thermally decomposing the azodicarbonamide. At least, the present invention relates to a smoker igniter which continuously smokes the smoker composition from the nozzle hole. That is, a rod-shaped exothermic agent that does not belong to explosives is placed in an exothermic agent storage tube, and an igniter to which an explosive such as a match head medicine is attached is combined with the characteristics of the smoker composition and the material of the film bag,
The plume can be started and continued more efficiently and smoothly.

The pyrethroid insecticides used in the present invention include phenothrin, permethrin, cyphenothrin,
Cypermethrin, allethrin, praletrin, framethrin, resmethrin, etofenprox, etc., which are fast-acting against pests and highly safe for humans and animals, so that they can be found in cockroaches, bedbugs, lice, house dust mites that live in the home. It is suitable for controlling or controlling dust mites. When an optical isomer or a geometric isomer based on an asymmetric carbon or a double bond is present in the chemical structure and the like, each or any mixture thereof is, of course, included in the present invention. is there. Particularly preferred compounds are phenothrin, permethrin, cyphenothrin and cypermethrin, which are expected to have more residual effects. Examples of the carbamate insecticide include methoxadiazone.

One or two selected from pyrethroid insecticides and carbamate insecticides are suitably incorporated in the smoker composition in an amount of 2 to 15% by weight. 2% by weight
If it is less than 15%, the desired effect cannot be obtained. On the other hand, if it exceeds 15% by weight, the jetting power of the blowing agent is undesirably affected.

In the present invention, in addition to the above insecticides, other types of insecticides, acaricides, fungicides, fungicides, fungicides, fungicides, and pyrethroid insecticides. Synergists, stabilizers, perfumes, excipients and the like may be added. Examples of the insecticide include organophosphorus insecticides such as fenitrothion, dichlorvos, diazinon, and tocthione.
Alternatively, compounds such as silafluofen, hydroprene, and pyrifenoxyphen can be exemplified. Examples of the acaricide include phenyl salicylate, 3-iodo-2-propynylbutyl carbamate, and the like.
Examples of antibacterial agents and bactericides include 2-mercaptobenzothiazole, 2- (4-thiazolyl) benzimidazole, triforine, 3-methyl-4-isopropylphenol,
Examples thereof include o-phenylphenol, but are not limited thereto.

In the present invention, as the blowing agent, a smoke-absorbing composition obtained by blending azodicarbonamide with a specific auxiliary agent, that is, one or two selected from zinc oxide and zinc carbonate, is suitably used. Azodicarbonamide has low odor peculiar to the foaming agent and exhibits excellent foaming performance due to a large amount of gas. Insecticidal components have the disadvantage of being difficult to apply. However, the present inventors can lower the decomposition temperature of azodicarbonamide by adding a specific amount of one or two selected from zinc oxide and zinc carbonate to azodicarbonamide and belong to explosives. Finding that a method of combining a rod-shaped exothermic agent into an exothermic agent storage tube and combining it with an igniter attached with an explosive such as a match head medicine is extremely useful in providing an efficient smoker system It was done. On the other hand, other adjuvants known to lower the decomposition temperature of the organic foaming agent, such as zinc stearate, zinc octoate, calcium stearate, urea, melamine, guanidine, etc., alone can provide efficient smoking performance. Did not.
Further, as another means for lowering the decomposition temperature of the organic blowing agent,
There is also a method of mixing other types of blowing agents having a low decomposition temperature, but there are many problems for home use because an unpleasant odor cannot be avoided.

The azodicarbonamide in the blowing agent is preferably blended in an amount of 70 to 97% by weight based on the total amount. 70
%, The blowing power of the blowing agent is insufficient, and the insecticidal component may not be sufficiently diffused. The amount of one or two selected from zinc oxide and zinc carbonate is preferably in the range of 1 to 15% by weight, more preferably 2 to 5% by weight, based on the total amount. If the amount is less than 1% by weight, the effect of the adjuvant cannot be obtained. If the amount exceeds 15% by weight, although the jetting power is increased and the time required for smoking is reduced, the volatilization rate of the insecticidal component is reduced, and after the smoking. This is not preferable because the contamination due to the settling of the auxiliary agent becomes noticeable. The azodicarbonamide foaming agent blended with an auxiliary agent thermally decomposes at 140 ° C. to 205 ° C., and allows continuation of smoking even with a small heat source, but as long as the smoke performance is not hindered,
Other auxiliary agents described above may be added.

The fumigation agent suitably used in the present invention is obtained by encapsulating a fumigation composition in a synthetic resin film bag in consideration of simplicity. As a material of the synthetic resin film bag, polyethylene, polypropylene, nylon, polyester and the like can be generally used, but as a result of examining to efficiently maintain the plume, the thickness is preferably about 20 to 50 microns, and polyethylene is preferably used. Those obtained by laminating the film with another synthetic resin film, such as polyethylene-laminated cellophane and polyethylene-laminated polypropylene, were particularly effective. If the smoking agent is put in a heat-resistant container provided with a smoke hole equipped with the smoke igniter of the present invention and the explosive is ignited, the smoke can be smoothly and efficiently continued. The material of the heat-resistant container is paper, ceramic,
Examples thereof include plastic and metal.

According to a fifth aspect of the present invention, the amount of each component in the smoker composition is specified in a preferable range as described above.
