Problems solved by technology

In this insect repellant, the end point of volatilization of the volatile agent at room temperature and the end point of sublimation of the sublimation substance are basically at the same time, but, as shown in the examples, ethynthrin is compared to the sublimation substance Sunsapry (2, 4,6-triisopropyl-1,3,5-trioxane) content is high, even if a non-woven fabric with a large mesh weight (weight per unit area of ​​Japanese textile fabrics) is used, the danger of chemical leakage cannot be avoided. It is also difficult to adjust the speed of volatilization and sublimation with large non-woven fabrics
Furthermore, since it is necessary to form a gas permeation suppressing layer on a part of the inner surface of the air-permeable material, the structure is complicated, and there are also problems in manufacturability, and it cannot be said that it can certainly meet the practical requirements.

Embodiment 1

[0045] figure 1 A cross-sectional view showing an example of the insect repellent of the present invention (both sides of the flexible bag are made of Japanese paper).

[0046] The insect repellant 1 is composed of a flexible bag 3 containing a drug carrier 2 formed by carrying a volatile drug at room temperature on a sublimable substance. The flexible bag 3 is made of Japanese paper 4 and laminated thereon. The drug-permeable film 5 on the inner surface is formed.

[0047] In this example, the following design was carried out, that is, 10 mg of ethynthrin, which is a volatile drug at room temperature, was supported on 1.0 g of disc-shaped sunsupri (colored in blue) with a thickness of 5 mm, and The drug carrier 2 was prepared (the drug loading amount relative to the sublimable substance: 1.0%), four of which were placed in a drawer with a capacity of about 50 L, and used for 3 to 4 months. In addition, the unit payment of Japanese paper is 20g / m 2 , the wall thickness of t...

Embodiment 2

[0050] figure 2 A cross-sectional view showing another example of the insect repellent of the present invention (a flexible bag made of Japanese paper on one side and a drug-impermeable film on the other side).

[0051] One side of the flexible bag 3 is composed of Japanese paper 4 and a drug-permeable film 5 laminated on the inner surface thereof, and the other side is a drug-impermeable polyester film 6 .

[0052] In this example, the following design was carried out, that is, 120 mg of ethynthrin, which is a volatile drug at room temperature, was supported on 10 g of disc-shaped sansupri (colored blue) with a thickness of 7 mm, and prepared Four of the finished drug carrier 2 (the drug loading amount relative to the sublimable substance: 1.2%) were placed in a suit wardrobe with a volume of about 800 L and used for one year. In addition, the unit payment of Japanese paper is 25g / m 2 , the wall thickness of the polyethylene used for its inner surface lamination is 12 μm. ...

Embodiment 3

[0055] According to Example 1, various drug carriers 2 and flexible bags 3 shown in Table 1 were prepared. Table 2 shows the results of the volatilization test by placing them in a 50-L suitcase at 25°C. In addition, the residual amount of the normal temperature volatile chemical and the sublimation substance over time is expressed as a relative ratio to the initial value.

[0056] [Table 1]

[0057]

[0058] [Table 2]

[0059]

[0060] In the case of the insect repellent of the present invention, the volatilization of the volatile agent at room temperature and the sublimation of the sublimation substance proceed substantially in parallel, and both are completed substantially at the same time, so it was confirmed that the present invention has an excellent endpoint display function. In addition, by changing the size and material of the flexible bag, it is possible to set a usage period of 3 to 4 months, 6 months, or 1 year according to the application.

Abstract

The present invention provides a insect-proofing agent, which has high insect-proofing effect, at the same time, can display using terminal definitely due to the volatilization of normal temperature volatility medicament and the sublimation of subliming material end at one time, also manufacturability is excellent. The insect-proofing agent is characterized in that it contains medicament carrier by pliability bag, the medicament carrier is made by making one or two normal temperature volatility medicament selected from the eneyne pyrethrin, tetrafluoro pyrethrin, bingfu pyrethrin and methoxy benzyl fluorine pyrethrin to be carried on subliming material with 0.5 to 2.0 percent by weight. The two or single surface of the pliability bag is coated with japanese paper or non-slub cloth of 10 to 50g / m<2> and medicament permeance film which wall thickness is 10 to 30 [mu]m, under the state of single surface, the other surface is formed by non permeating film, and at least parts of the medicament carrier can contact to the inner surface of the pliability bag even though the medicament carrier reduces along with the sublimation of the subliming material, thus, the using terminal can be identified by watching the disappear state of the medicament carrier.

Description

technical field [0001] The present invention relates to an improvement of an insect repellant, which is realized by accommodating a drug carrier in a flexible bag, and the drug carrier is constituted by carrying a sublimation substance with a volatile drug at room temperature. Background technique [0002] At present, as insect repellents for clothing, sublimable insect repellents such as solid p-dichlorobenzene, naphthalene, camphor, etc., and liquid room temperature volatile agents such as empenthrin (empenthrin) are known to be impregnated into paper, plastics, etc. An insect repellent formed after being placed in a carrier such as a container, and then loaded into a container. [0003] The former sublimation insect repellant is weak against clothing pests such as clothes moth and black fur beetle, and has problems in terms of harmfulness and environmental pollution. On the other hand, room-temperature volatile pyrethroid agents such as ethynthrin, etc., have higher inse...
