Description

[Detailed description of the invention] The present invention utilizes air or water, or a pyrogenic composition that generates heat in the presence of air and water, to heat agents such as insecticides, fungicides, or fragrances. This invention relates to a simple chemical fumigation tool that can perform functions such as insecticidal, sterilizing, and aroma imparting.

Conventionally, fumigation sheets or mats have been known in which pesticides, bactericides, aromatics, etc. that volatilize by heating are applied or impregnated in the form of solutions or dispersions onto drug-retaining substrates such as synthetic resin sheets or compressed non-woven mats. These sheets or mats are usually heated using a heating wire or a heating plate to volatilize the insecticidal/sterilizing active ingredient or the aromatic ingredient in the base material, thereby exerting their respective desired effects.

However, as mentioned above, since electric power is used as a heating means, the use has so far been limited to indoor use.

On the other hand, when enjoying outdoor leisure activities such as camping and fishing, people are often troubled by mosquitoes, flies, lice, and other pests. Therefore, countermeasures such as applying insect repellent liquid to the skin or burning mosquito coils are taken, but the former may not be applicable to people with skin diseases or allergies. In the latter case, there is a risk of getting burned or, in the worst case, causing a fire.

These drawbacks can be overcome by using the aforementioned chemical fumigation sheets or mats, but in this case, problems remain with the heating means.

In this case, a heat-generating composition made by mixing iron powder and an oxidizing agent or granular caustic soda with a water retention agent such as calcium carbonate is stored in a breathable inner bag, and this inner bag is further covered with an air-blocking resin film. Heat-generating heat-retaining devices sealed in an airtight outer bag made of metal foil or the like have been known so far. These heat-retaining devices can be used by removing the air-permeable inner bag from the airtight outer bag or, if necessary, by loosening the heat-generating composition inside the inner bag. Alternatively, in the presence of air and water, it generates heat at a relatively high sensible temperature (50°C to 70°C) and maintains the exothermic action for 7 to 8 hours.

Therefore, the present invention focused on the heat generating effect of the heat-generating heat insulating device described above over a relatively long period of time, and by utilizing this as a heating means for the above-mentioned chemical fumigation mat, it can kill insects and kill insects outdoors without electrical equipment. The purpose is to provide a simple chemical fumigation device that can exert a sterilizing effect or an aroma imparting effect in an outdoor living space such as a tent, and its main point is to use air or water, or air and water. The drug layer containing the vaporizable drug is heated by a heating element made of an exothermic composition that generates heat in the presence of the vaporizable drug.

In the present invention, the drug layer is a drug-retaining base material such as paper, non-woven fabric, synthetic resin film, etc., containing a known insecticide/bactericide that volatilizes by heating, such as α-bromocinnamaldehyde or pyrethroid insecticide, or a desired known flavoring agent. It is made by impregnating it or kneading it into it.

On the other hand, the heating element is a synthetic resin film, paper, non-woven fabric, etc. with many small holes made of air, water, or a known exothermic composition that generates heat in the presence of air and water. It is housed in an inner bag made of breathable material.

As is already clear, the insecticidal active ingredient or aromatic ingredient in the upper drug layer is volatilized by heating with the heating element, so the two need to be in close contact with each other.

According to one embodiment of the present invention, an air-permeable drug-retaining base material such as paper, nonwoven fabric, or synthetic resin film (in which case, a large number of small holes are perforated) impregnated with or kneaded with a drug as described above. In this way, an inner bag containing the exothermic composition is formed. This breathable inner bag is further enclosed within an airtight outer bag made of an air-blocking synthetic resin film, metal foil, or the like. The drug may be contained on the entire surface of the flat inner bag, or may be contained only on one of the upper and lower sides of the inner bag.

According to another embodiment of the present invention, the drug holding base material is made in the form of a sheet or a small piece of mat separately from the breathable inner bag of the heating element, and the drug holding base material is made in the form of a sheet or a small piece of matte separately from the breathable inner bag of the heating element, and the drug holding base material is formed on the surface of the inner bag through an adhesive at the time of use. affixed to. It is convenient if the adhesive is applied in advance to one side of the drug-holding base material or to an arbitrary location on the surface of the air-permeable inner bag of the heating element. In addition,
The surface of the adhesive layer is covered with a separator in a conventional manner. Further, the drug holding base material is housed together with the heating element in an airtight outer bag, or is housed in a separate airtight bag and attached to the heating element.

The heating element housed in the airtight bag, or the heating element and the drug holding base material, may be further housed in a box made of synthetic resin, for example, which has a large number of small holes, and the box body has the airtightness. Once removed from the bag, the heating element and drug-holding substrate can be housed therein for use in fumigation.

As described above, the chemical fumigation device of the present invention utilizes as a heating means a heating element in which a pyrogenic composition that generates heat in the presence of air, water, or air and water is housed in a breathable inner bag, The inner bag itself contains an insecticidal bactericide or aromatic agent that volatilizes when heated, or the inner bag is configured so that a drug holding base material containing the drug can be applied to the surface of the inner bag, At least the heating element is enclosed in an airtight outer bag, so when enjoying outdoor recreational activities such as camping or fishing outdoors where there is no electrical equipment, the fumigation device of this invention can be carried in a corner of a backpack or carry bag. However, when necessary, if the heating element and drug holding base material are removed from the airtight outer bag, or both are taken out and combined, the drug will be volatilized by the high temperature heat (approximately 50°C to 70°C) emitted by the heating element. It exerts its insecticidal, sterilizing, and fragrance-imparting effects over a long period of time (about 7 to 8 hours). Moreover, since the proposed fumigation tool does not use electricity or fire at all, there is no risk of electrical leakage or electric shock, and there is no risk of burns or injury.
There is no risk of fire or the like.
