[0030] (Container body) The pest control tool of the present invention includes a container body that contains a chemical agent containing a pest repellent component and an organic solvent.

[0031] Here, taking the illustrated embodiment as an example, the main container 2 is a container for containing the drug 1. It has a thin, generally box-like shape and an opening on one side. The drug 1 is filled through the opening, and the opening is sealed with a volatilization film 3. As shown in FIG. 1 , the main container 2 may have a storage section 21 on the upper vertical side for storing most of the drug 1, and multiple flow paths 22 that communicate with the storage section 21 and extend downward. The flow paths 22 are shorter than the storage section 21 in the width direction perpendicular to the vertical direction, longer than the storage section 21 in the up-down direction, and the volume of the storage section 21 is larger than the volume of the flow path 22. By providing such storage sections 21 and flow paths 22, most of the portions of the volatilization film 3 that can contact the drug 1 can remain in contact with the drug 1 over a long period of time, thereby preventing the amount of drug 1 volatilizing from the volatilization film 3 from varying significantly between the beginning, middle, and end of use. In this embodiment, the flow path section 22 is formed in a straight line extending vertically downward from the storage section 21, but in other embodiments, it may be in a broken line shape such as a "L" shape or a zigzag shape, or in an arc shape, as long as the drug 1 flows vertically downward from the storage section 21.

[0032] The main container 2 is typically a laminate of an olefin-based resin layer and a polyethylene terephthalate layer. An alicyclic olefin-based resin may also be used as appropriate. The olefin-based resin layer is, for example, a layer containing polypropylene and / or polyethylene. When main container 2 is formed from a laminate, one or more layers of the laminate may be colored layers.

[0033] Here, the colored layer is a layer in which one or more colors are applied to the entire surface or at least 60% or more of the entire surface. Typically, it is a solid color, but it may also comprise letters, figures, or patterns. The colored layer may typically be a colored polyethylene terephthalate layer. Here, coloring methods include kneading a colorant such as ink, pigment, or dye into the resin, as well as printing a colorant onto a resin sheet.

[0034] The container body is not limited to any particular structure, but may be, for example, a structure obtained by molding a laminate consisting of a colorless polyethylene layer or polypropylene layer and a polyethylene terephthalate layer having a colorant kneaded into it; a structure obtained by molding a laminate consisting of a colorless polyethylene layer or polypropylene layer and a colorless polyethylene terephthalate layer whose surface has been printed with a colorant; a structure obtained by molding a laminate in which a colorless polyethylene layer or polypropylene layer and a colorless polyethylene terephthalate layer whose printed surface has been printed with a colorant are further laminated with a colorless polyethylene terephthalate layer; or a structure obtained by molding a laminate in which a polyethylene terephthalate layer and a colorless polyethylene layer or polypropylene layer are laminated with the printed surface of a printed colorless polyethylene terephthalate layer.

[0035] The ink used to form the colored layer is a mixture of a binder resin with an appropriate amount of a colorant such as a pigment or dye, an extender pigment, a solvent, a stabilizer, a plasticizer, a catalyst, a curing agent, etc. Examples of binder resins include acrylic resins, styrene resins, polyester resins, polyurethane resins, chlorinated polyolefin resins, vinyl chloride-vinyl acetate copolymer resins, polyvinyl butyral resins, alkyd resins, petroleum resins, ketone resins, epoxy resins, melamine resins, fluorine-containing resins, silicone resins, cellulose derivatives, and rubber resins. These may be used alone or in combination of two or more.

[0036] The thickness of the container body is preferably about 100 to 700 μm, and more preferably about 200 to 600 μm.

[0037] One embodiment of the laminate of the container body is preferably, but not limited to, a polyethylene layer or a polypropylene layer disposed on the inside where the drug is contained.

[0038] The container body is colored in the L*a*b* color space with an L value of 80 or less and a b value of 60 or less, preferably an L value of 20 to 80 and a b value of -50 to 50. The measurement is performed by preparing a 5 cm square laminate (film) containing the colorant that constitutes the container body and measuring it with a spectrophotometer CM-5 (manufactured by Konica Minolta). The measurement is performed in transmitted color measurement mode to obtain the L value, a value, and b value. The measurement is performed three times and the average value is calculated.

[0039] Visible colors include, but are not limited to, one color or a combination of two or more colors selected from the group consisting of green, red, purple, blue, magenta, black, and gray.

[0040] (Volatile film) The volatilizing film 3 is a member that seals the opening of the main container 1 and can be made of, for example, low-density polyethylene or polypropylene. The volatilizing film 3 does not allow the liquid drug 1 to pass through, but allows the vaporized drug 1 to pass through. When low-density polyethylene, for example, is used as the volatilizing film 3, it has a lower crystallinity than general polyethylene, with a density of 0.910 to 0.930, and much of the vaporized drug 1 passes through the amorphous portion and is dispersed to the outside. Among low-density polyethylenes, linear low-density polyethylenes with a density of 0.910 to 0.925 and few branched chains are more preferred. By using such linear low-density polyethylene, the amount of volatilized drug 1 contained therein can be adjusted so that it does not vary significantly depending on the time of use.

[0041] The thickness of the volatilization film 3 is preferably 50 to 100 μm, and more preferably 60 to 90 μm. With such a thickness, the volatilization rate of the enclosed drug 1 can be adjusted so that it does not change significantly depending on the time of use. In addition, the oxygen gas permeability of the volatilization film 3 is 1000 to 6000 cc / m in an environment of 23°C. 2 ·24hr·atm), and 1200 to 3000cc / (m 2 It is preferable that the gas permeability is in this range (24 hrs atm). When the gas permeability is in this range, the amount of volatilization of the agent 1 can be adjusted so that it does not vary significantly depending on the time of use, and the pest control effect tends to last for a long period of time, such as 200 days. The gas permeability is preferably measured by gas chromatography using the isobaric method described in JIS K 7126-2.

[0042] [Volatilization promotion method] The present invention also provides a pest control device comprising: an agent containing a pest repellent component and an organic solvent; a container body containing the agent; and a volatilizing film sealing an opening of the container body, The present invention relates to a method for promoting the volatilization of a pesticide using a pest control tool, the container body of which is a colored container having an L value of 80 or less and a b value of 60 or less in the L*a*b* color space. In the volatilization promotion method of the present invention, the various components and their contents, the properties of the container, etc. are the same as those described for the pest control tool. [Example]

[0043] Next, the present invention will be described in detail with reference to examples, but the present invention is not limited to the following examples. The unit of the amount of each component in the tables is w / v % unless otherwise specified in the tables.

[0044] Example 1 At room temperature of 20°C, 10 g of transfluthrin was added as a pyrethroid compound to a 200 ml Griffin beaker, and a chain hydrocarbon compound with branched chains having 10 to 16 carbon atoms was added as a liquid isoparaffin hydrocarbon until the total volume reached 100 ml. The mixture was stirred until uniformly dissolved, yielding a total of 100 ml of the drug (transfluthrin concentration 10 w / v%). The obtained drug was then placed in the main container 2 as shown in Figure 1 and stored in a container with an oxygen gas permeability of 2550 cc / (m 2 The pesticide was encapsulated in linear low-density polyethylene (LLDPE) with a film thickness of 70 μm to obtain a pest control device.

[0045] The container of this Example 1 was obtained by laminating a polyethylene terephthalate layer printed with red coloring onto a laminate consisting of a polyethylene terephthalate layer and a polyethylene layer, and then vacuum molding the laminate. The measured values ​​of the L*a*b* color space of the container body are as shown in Table 1.

[0048] Example 4 A pest control device was obtained in the same manner as in Example 1. However, the color tone of the container body used and the measured values ​​in the L*a*b* color space are as shown in Table 1.

[0049] Example 5 A pest control device was obtained in the same manner as in Example 1. However, the color tone of the container body used and the measured values ​​in the L*a*b* color space are as shown in Table 1.

[0050] (Comparative Example 1) A pest control device was obtained in the same manner as in Example 1. However, the color tone of the container body used and the measured values ​​in the L*a*b* color space are as shown in Table 1.

[0051] (Comparative Example 2) A pest control device was obtained in the same manner as in Example 1. However, the color tone of the container body used and the measured values ​​in the L*a*b* color space are as shown in Table 1.

[0052] [Table 1]

[0053] [Increase / decrease rate of drug volatilization] From July 8, 2021 to August 25, 2021, the pest control devices of the examples and comparative examples were left in the open air at the prevailing temperature and humidity. Five days after the start of the test, the amount of volatilized pesticide was measured as the weight loss, and the amount of volatilized pesticide was continuously measured under the same conditions. The results are shown in Figure 4.

[0054] The test results for the pest control devices of these Examples and Comparative Examples showed that after 44 days, the pest control devices of the Examples showed an improvement rate of up to 21.33% when the transparent container body was used as the standard. The improvement rates are summarized in Table 2. Here, the improvement rate was calculated using the following formula. Improvement rate (%) = (amount of drug volatilized in each example - amount of drug volatilized in Comparative Example 1) / amount of drug volatilized in Comparative Example 1

[0055] [Table 2]

[0056] As a result, it was confirmed that the pest control devices of the Examples exhibited significantly enhanced volatilization compared to the pest control devices of the Comparative Examples.
