In a house, windows and entrances are entrances for pests. As a method of suppressing the invasion of pests from the entry port, it is conceivable to place insect repellents in these places.

As an example of such an insect repellent, an insect repellent in which a volatile insect repellent is held in a net and stored in a container having an open window, or a net in which a volatilizing agent is held is fitted into a frame member. Tools (see Patent Document 1) and the like are known.

Japanese Unexamined Patent Publication No. 2006-314284

By the way, when the net is stored in a container and used, the volatilizing agent volatilizes from the surface of the net, and as a method of increasing the amount of volatilization, it is conceivable to fold the net and store it in the container. However, in this case, the nets are likely to come into contact with each other. If there are many contact portions between the nets, the volatilization of the drug in the contact portion may be hindered and the volatilization amount may decrease.

By the way, this problem may occur when a volatile agent such as a repellent, a fragrance, and an antibacterial agent is used in addition to the insect repellent.

Therefore, it is an object of the present invention to minimize the parts where the molded bodies containing the volatile agent can come into contact with each other and prevent the amount of the volatile agent from being reduced.

The present invention is a three-dimensional drug volatilizer in which a plurality of planar drug volatilizers composed of a resin composition containing a volatilizing agent are superposed, and the volatilizing agent comprises a room temperature volatilizing pyrethroid-based insecticidal component. The planar drug volatilizer is composed of an outer edge member and an internal member arranged inside the outer edge member, and the other planar drug volatilizer superposed on the planar drug volatilizer is between the two. The above-mentioned problem was solved by using a three-dimensional drug volatilizer bonded by the rib material provided in the above.

The drug volatilizer according to the present invention is a stack of a plurality of planar drug volatilizers made of a resin composition containing a volatilizing agent, and at the time of this stacking, a rib material is interposed and bonded. Therefore, it is possible to prevent the planar drug volatilizers from coming into contact with each other, control the volatilization of the volatilizing agent, and keep the planar drug volatilizer clean.

The three-dimensional drug volatilizer according to the present invention is a three-dimensional drug volatilizer formed by superimposing a plurality of planar drug volatilizers composed of a resin composition containing a volatilizing agent.

[Volatile drug]
The volatile agent refers to a pyrethroid insecticidal component having volatile properties at room temperature. Examples of this include transfluthrin, metoflutrin, empentrin, profluthrin, allethrin, flamethrin, prarethrin, resmethrin, phthalthrin, phenothrin, natural pyrethrin and the like.

In the present invention, in addition to the room temperature volatilizing pyrethroid insecticidal component, other insect repellents, repellents, air fresheners, deodorants, fungicides, antibacterial agents and the like may be used in combination.

Examples of the other insect repellent include organophosphorus insecticidal components such as dichlorvos, fenitrothion, and marathon, and insect growth regulators such as methoprene and hydroprene. Examples of the repellent include N, N-diethyltoluamide (DEET), dimethylphthalate, dibutylphthalate, 2-ethyl-hexanediol, dibutylsuccinate, p-menthane-3,8-diol and the like.

Examples of the fragrance include citronella oil, orange oil, lemon oil, lime oil, yuzu oil, lavender oil, peppermint oil, eucalyptus oil, jasmine oil, cypress oil, green tea essential oil, limonene, α-pinene, linalol, geraniol and phenyl. Examples thereof include ethyl alcohol, amylcinnamic aldehyde, and benzyl acetate. Examples of the deodorant include volatile ones such as hiba oil, cypress oil, bamboo extract, yomogi extract, pyruvic oil, ethyl pyruvate, and pyruvate ester such as phenylethyl pyruvate.

Examples of the fungicide include 2-n-octyl-4-isothiazolin-3-one, isopropylmethylphenol, orthophenylphenol and the like. Examples of the antibacterial agent include hinokitiol, tetrahydrolinalool, eugenol, citronellal, allyl isothiocyanate and the like.

In addition, although optical isomers or geometric isomers based on asymmetric carbons and unsaturated bonds may be present in the above compounds, it goes without saying that each of them alone or an arbitrary mixture is also included in the present invention. Is.

[Resin composition]
The resin composition is a composition for forming a planar drug volatilizer, and is a composition in which the resin contains the volatilizer or the like.

The resin is not particularly limited as long as it is possible to gradually volatilize the volatile agent contained therein from the surface as it is or when a carrier described later is used.
For example, polyolefin resins such as branched low density polyethylene (LDPE), polyethylene (PE) such as linear low density polyethylene (LLDPE), polypropylene (PP), or carboxylic acid esters (vinyl acetate, methyl methacrylate). , Ethyl methacrylate, etc.) and polyolefin-based copolymers and the like. Such a carboxylic acid ester is effective in controlling the volatilization of the volatile agent from the resin surface, and generally, the higher the blending ratio of the carboxylic acid ester with the polyolefin resin, the slower the bleeding rate of the volatile agent tends to be. .. In the present invention, an ethylene-vinyl acetate copolymer (EVA), an ethylene-methyl methacrylate copolymer (EMMA), or the like in which 1 to 35% by weight of a carboxylic acid ester is blended with respect to a polyolefin resin is preferably used. Will be done.
Further, a polymer blend in which the content ratio of the polyolefin-based copolymer and the homopolymer of the olefin is adjusted and mixed can be used, and if necessary, another polymer compound such as a styrene-based elastomer may be contained. You can also.
The carboxylic acid ester means an unsaturated carboxylic acid ester or a carboxylic acid vinyl ester.

In addition to the volatile agent, a carrier such as talc, alumina, silica, or white carbon may be used in combination with the resin composition, and a colorant, a stabilizer, an antistatic agent, or the like may be appropriately added to the resin composition. You may mix it. When a carrier is used, it is convenient to use a manufacturing process in which a masterbatch in which a resin contains a high concentration of a volatilizing agent is prepared in the first step, and the resin is further diluted to a predetermined concentration in the second step. Is. In addition, communication bubbles may be generated from the inside of the resin composition to the surface portion, and the volatile chemicals inside may easily bleed to the surface.

The content of the volatile agent in the resin composition is appropriately determined depending on the type of volatile agent to be used, the type of resin, the environment of use, the period of use and the like. It is necessary to increase the content of the volatilizing agent as the period of use becomes longer, but it is appropriate to set the content in the range of 1 to 20% by weight. If it is less than 1% by weight, it is difficult to secure the amount of drug required to exert the effect, while if it exceeds 20% by weight, it becomes difficult to mold after kneading the volatile agent, and further, the resin surface In some cases, the volatilizing agent bleeds excessively, which may cause a problem that stickiness is likely to occur.

When the carrier is used, the amount of the carrier used in the resin composition is preferably 5 parts by weight or more, preferably 10 parts by weight or more, based on 100 parts by weight of the volatile agent to be used. If it is less than 5 parts by weight, the ability to retain the volatile agent is inferior and it becomes difficult to manufacture by masterbatch. On the other hand, the upper limit of the amount of the carrier used is preferably up to 50 parts by weight, preferably about 35 to 40 parts by weight, based on 100 parts by weight of the volatile agent. If it is more than 50 parts by weight, it may affect the strength of the three-dimensional drug volatilizer and the bleeding property of the volatilizer.

Specifically, a rib material 14 is arranged between two planar drug volatilizers 11, and one end of the rib material 14 is bonded to one planar drug volatilizer 11, and the other of the rib materials 14 is bonded. By binding to another planar drug volatilizer 11 at the end, the two planar drug volatilizers 11 are bonded via the rib material 14. The rib material 14 can prevent the adjacent planar chemical volatilizers 11 from coming into direct contact with each other. The member of the planar chemical volatilizer 11 on which the rib member 14 is arranged may be an outer edge member 12 or an inner member 13.
The type of the volatilizing agent contained in the plurality of planar drug volatilizers 11 constituting the three-dimensional drug volatilizer 10 according to the present invention is the same volatilizing agent for each planar drug volatilizer 11. It may be a different volatile agent.

If the rib material 14 is molded from the resin composition, the surface area of the three-dimensional drug volatilizer 10 according to the present invention can be increased, which leads to an increase in the volatilization amount of the volatilizing drug. preferable.

The rib material 14d having a protrusion in the middle, as shown in FIG. 1 (g), has a Y-shape, and one outer edge member 12 (or inner member 13) to be connected is bifurcated. The rib material 14e having a shape sandwiched between the portions may be an H-shaped rib material or an X-shaped rib material having the same effect as the bifurcated portion of FIG. 1 (g), although not shown. By using such various rib materials, the surface area of the rib material itself can be increased, and the amount of volatilization of the volatilizing agent can be increased.

The number of rib materials 14 used is not particularly limited, and is not particularly limited as long as it is possible to prevent the adjacent planar chemical volatilizers 11 from coming into direct contact with each other, and two or more are preferable. Three or more are preferable. Further, the upper limit of the number is not particularly limited because it leads to an increase in the amount of volatilization of the volatilizing agent.

The formation of the bond between the rib material 14 and the planar chemical volatilizer 11 (in the rib material 14e of FIG. 1 (g), the portion of the rib material opposite to the bifurcated portion) is not particularly limited, but for example, In the outer edge member 12 and the inner member 13 constituting the planar chemical volatilizer 11, a recess is provided at a position where the rib member 14 is arranged, and the rib member 14 is incorporated in the recess to form a bond. When a bifurcated portion such as the rib material 14e of 1 (g) is provided, a bond may be formed by sandwiching the outer edge member 12 or the inner member 13 constituting the planar chemical volatilizer 11 between the bifurcated portions. At the time of molding the planar chemical volatilizer 11, there is a case where the rib material 14 is integrally molded to form a bond.
By forming these bonds, the rib member 14 and the outer edge member 12 and the inner member 13 can be more firmly bonded.

When the rib material 14 is integrally molded to form a bond at the time of molding the planar chemical volatilizer 11, the tip portion of the rib material 14 is bifurcated and has an outer edge as in the rib material 14e of FIG. 1 (g). Except for the case where the member 12 or the internal member 13 is sandwiched, as described above, the outer edge member 12 or the internal member 13 constituting the planar chemical volatilizer 11 is provided with a recess at the place where the rib material 14 is arranged. It is preferable to form a bond by incorporating the rib material 14 in the recess.

As a specific example of the three-dimensional drug volatilizer 10, the three-dimensional drug volatilizer 10a shown in FIG. 1 (b) using the planar drug volatilizer 11a shown in FIG. 1 (a) can be mentioned. The three-dimensional drug volatilizer 10a is obtained by superimposing a plurality of planar drug volatilizers 11a and joining the adjacent planar drug volatilizers 11 to each other via the rib material 14 arranged between them. is there.

In addition, the three-dimensional drug volatilizer 10b shown in FIG. 2B using the planar drug volatilizer 11b shown in FIG. 2A can be mentioned. As shown in FIG. 2A, the planar drug volatilizer 11b is formed by connecting at least two of the plurality of planar drug volatilizers 11a with a connecting member 15. In FIG. 2A, the three planar drug volatilizers 11a are connected by using the two connecting members 15. By doing so, the group of the planar drug volatilizer 11 used as one set can be clearly grasped. In order to use this planar drug volatilizer 11b to form a three-dimensional drug volatilizer 10b, by bending the connecting member 15, specifically, the joint portion between the connecting member 15 and the outer edge member 12 or its vicinity thereof. By bending at least two of the above, the two connected planar drug volatilizers can be arranged so as to face each other and superposed. Then, by arranging the rib material 14 between them, the two opposing planar chemical volatilizers 11 can be bonded to each other via the rib material 14.

Further, the three-dimensional drug volatilizer 10c shown in FIG. 3 (b) using the planar drug volatilizer 11c shown in FIG. 3 (a) can be mentioned. As the three-dimensional drug volatilizer 10c, a plurality of perfect circular planar drug volatilizers 11 having different inner diameters (11ca to 11cc in FIG. 3 (b)) are used, and this is shown in FIG. 3 (b). The next large planar drug volatilizer 11cc is arranged on the upper surface side and the lower surface side of the planar drug volatilizer 11ca having the largest diameter, and the next smallest planar drug volatilizer is placed outside the planar drug volatilizer 11cc. Arrange 11cc. Then, by arranging the rib material 14 between the opposing planar drug volatilizers, the opposing planar drug volatilizers can be bonded via the rib material 14. As a result, in FIGS. 3A to 3D, a three-dimensional drug volatilizer 10c having a shape in which two truncated cones are overlapped on a surface having a large diameter can be obtained. In this case, the shape of the outer edge member 12 of the planar drug volatilizer 11 to be used, the size, number and shape of the planar drug volatilizer 11 to be used, the order of arrangement of the planar drug volatilizers 11 having a plurality of sizes, etc. By devising other shapes, for example, a shape in which two truncated cones are overlapped on a surface with a small diameter, a shape in which two truncated cones are overlapped, and a shape in which the height and flatness are changed, the central part It is possible to obtain a three-dimensional drug volatilizer having a shape such as a donut with a hole in the cone.

By the way, as the shape of the three-dimensional drug volatilizer 10, as shown in FIG. 2B, the shapes of the two planar drug volatilizers 11 facing each other are the same, and when they are overlapped, they are exactly overlapped with each other. Or, as shown in FIG. 3 (b), when planar drug volatilizers 11 having similar shapes of different sizes are used and these are overlapped, other than the shapes that do not exactly overlap, FIG. 2 (c) ), The shapes of the two opposing planar drug volatilizers 11 are the same, but when they are overlapped, they do not exactly overlap, or, although not shown, the two opposing planar drugs. The shape of the volatilizer 11 is different, such as a triangle and a quadrangle, and when these are overlapped, a shape that does not exactly overlap can be mentioned.

[Storage container]
In the resin composition, the volatilizing agent bleeds on the surface of the planar drug volatilizer and volatilizes from the surface. Therefore, when the planar drug volatilizer is touched by a hand, the volatilizing agent adheres to the hand. There is a fear. Therefore, it is preferable that the three-dimensional drug volatilizer obtained by assembling this planar drug volatilizer by the method described later is stored in a storage container for use.

As a plastic container for storing the drug volatilizer, the three-dimensional drug volatilizer inside is hard to touch, the above-mentioned three-dimensional drug volatilizer can be stored, and the room temperature volatilizing pyrethroid insecticidal component is stably volatilized. If possible, the shape and size are not particularly limited, but from the viewpoint of volatilization efficiency, the ratio (opening ratio) of the opening to the container is in the range of 10 to 50% of the total surface area of the container. It is preferable to do so.

As long as the area of the opening is within the above range, the opening may be opened not only on the front surface and the back surface of the storage container but also on the side surface, the upper surface surface, and the lower surface surface, and the shape of the opening portion is particularly high. It is not limited.

The shape of the storage container is also not particularly limited, but when a rectangular parallelepiped three-dimensional drug volatilizer 10a or 10b is used, the rectangular parallelepiped storage container 21a shown in FIG. 4A is used in correspondence with this. When a three-dimensional drug volatilizer 10c having a shape in which two truncated cones are overlapped is used, the spherical storage container 21b shown in FIG. 4B is used in correspondence with the three-dimensional drug volatilizer 10c. However, play in the storage container is reduced and rattling can be prevented. The spherical shape includes a true spherical shape and an elliptical spherical shape.

Examples of the structure of the plastic container include a bent flat sheet-shaped plastic member, an integrally molded plastic product, and the like.
In the case where the flat sheet-shaped plastic member is bent, the container is assembled by using two of the bent members as a set so that the bent surfaces of the respective members overlap each other.

Further, a tongue piece portion having a notch may be provided at the end portion of the bent surface of the bent member, and the hook portion may be extended so that the tongue piece portion can be folded back and raised. In this case, a storage window for folding the hook portion may be provided above the back surface. This makes it possible to use the product according to various usage methods.
That is, when the tip portion of the hook portion shown here is locked to the above-mentioned container, for example, the upper surface portion, the container is blown off by wind when used outdoors, or when hung indoors, when used. Problems such as accidental dropping are eliminated, and a certain effect can be expected where you want to use it.

Next, the integrally molded plastic product may be molded by ordinary injection molding or vacuum forming regardless of the molding method, but the upper surface and the lower surface and the front surface and the back surface may be integrated by using a hinge. , The manufacturing process can be further simplified if they are integrated by fitting. Further, in this case, if a hook portion is provided on the upper surface portion of the container so that it can be raised, it can be used more effectively.

That is, similarly to the above, if the tip portion of the hook portion shown here can be locked to a part of the container, for example, an opening or a recess provided on the upper surface at the time of use, in the case of outdoor use, When the container is blown by the wind or hung indoors, problems such as accidental dropping during use can be eliminated, and a reliable effect can be expected at the place where the container is to be used.

In addition, which part of the container to lock is a matter to be appropriately selected at the time of manufacturing, but if it is locked on the same surface as the surface on which the hook portion is provided, the container can be moved from the installation position at the time of use. It is preferable because it can prevent the container from moving.

Various plastic materials such as polyethylene terephthalate, polyethylene, polypropylene, polybutylene terephthalate, nylon, and polyamide can be used as the plastic material used for these flat sheet-shaped plastic members and integrally molded plastic products, but the strength is high. In consideration of the above and its properties, it is preferable to use polyethylene terephthalate (PET) or polybutylene terephthalate (PBT).

Although various thicknesses of these plastics can be used, those having a thickness of 0.05 to 2 mm can be used from the viewpoint of the shape of the resin carrier, its relationship with its volatilization performance, economic efficiency, and the like. preferable.

[Storage bag]
The drug volatilizer of the present invention is generally stored in a storage container, then stored in a drug-impermeable film bag and put on the market, and is opened at the time of use. Of course, only the drug volatilizer may be contained in a drug impermeable film bag and put on the market, and the drug volatilizer taken out from the bag at the time of use may be loaded into the storage container. Here, examples of the material of the drug impermeable film bag include polyester (PET, PBT, etc.), polyamide, polyacetal, polyacrylicnitrile, and the like, and the wall thickness thereof is determined within a range that does not impair flexibility. In addition, in order to impart heat-sealing property, the inner surface of these chemical impermeable films can be laminated with polyethylene, polypropylene film or the like.

It was kneaded to produce a pelletized masterbatch.
Next, 100 parts by weight of the obtained pellets and 300 parts by weight of the LDPE were kneaded at 120 to 140 ° C., and then the obtained resin composition was injection-molded. As shown in FIG. 1A, the outer shape is rectangular, as shown in Table 1. The number of grid-like planar drug volatilizers having the outer shape shown in Table 1 was prepared. At this time, a rectangular parallelepiped rib material having the sizes shown in Table 1 was simultaneously formed on each planar chemical volatilizer by integral molding. The number of ribbed materials formed was as follows. Further, when a three-dimensional drug volatilizer is produced using the obtained planar drug volatilizer, Table 1 shows the locations of the outer edge member and the inner member of the planar drug volatilizer facing each other at the tips of the rib materials. A rib material incorporating portion (recess) having the size shown was formed at the same time as the molding of the above-mentioned planar chemical volatilizer.

Furthermore, in Example 3, the number was set to 8 for the first-stage planar drug volatilizer and 0 for the second-stage planar drug volatilizer.
On the other hand, in Comparative Examples 1 to 3, since the rib material was not used, the rib material and the recess were not formed during the molding of all the planar chemical volatilized bodies. Then, the planar drug volatilizers to be used were directly superposed to form a three-dimensional drug volatilizer. In Comparative Example 4, since one planar drug volatilizer was used, this was treated as it was as a three-dimensional drug volatilizer.
Each of the obtained three-dimensional drug volatilizers was hung indoors, and the volatilization amount and volatilization time of the volatilizing drug were measured under the conditions of 25 ° C. and a wind speed of 0.5 m. The volatilization amount and the volatilization time were measured by measuring the weight of the three-dimensional drug volatilizer over time.
As a result, the time of volatilization of the drug and the average volatilization amount over the entire period are as shown in Table 1.
