Description

The present invention relates to improvements in insect repellent containers.

Conventionally, insect repellents using room temperature volatile insect repellent components have been widely used. The insect repellent is impregnated with a matt, sheet-like or granular cellulose or non-woven carrier with an insect repellent component and stored in a plastic case with volatilized holes or a breathable non-woven inner bag. It is common to make it. In general, insecticides are marketed in a non-breathable plastic bag or aluminum bag so that the room temperature volatile insecticide does not lose due to volatilization during long-term storage or distribution. The insect repellent is taken out. However, polyethylene (PE) and polypropylene (PP) are mainly used as sealants for plastic bags and aluminum bags from the viewpoint of sealing performance and economical efficiency during bag making. Even when plastic bags were used, some of the insect repellent components adsorbed on the sealant, and some loss was inevitable. In the case of a plastic bag or an aluminum bag, once the bag is broken, it is difficult to ensure the sealing property. Further, in the storefront display, there is a problem that the mounting state becomes unstable.

By the way, the same problem exists also about the plastic case in which the carrier containing the room temperature volatile pyrethroid is contained as an insect repellent component, and various proposals have been made so far to prevent loss due to adsorption. For example, Japanese Patent Publication No. 2816363 describes a plastic case in which the material of the case is changed from polypropylene to polyester or polyamide, and Japanese Patent Application Laid-Open No. 11-187797 discloses a case using an amorphous cyclic olefin polymer. Has been. However, these are only related to the improvement of the material of the case, and the fact is that little attention has been paid to the packaging form for directly storing the insect repellent.
Japanese Patent Publication No. 2816363 JP-A-11-187797

The present invention provides a container for an insect repellent that is free from loss due to adsorption of room temperature volatile insect repellent components during long-term storage and distribution, and is advantageous not only in usability, moldability and economy, but also in store display. The purpose is to do.

In order to solve the above problems, the present invention employs the following configuration.
(1) A container composed of a lid and a body that can be opened and closed directly by encapsulating an insect repellent containing a room temperature volatile insect repellent component, and the lid and the body are molded from a non-drug-adsorbing plastic.

(Wherein X and Y are the same or different and represent a hydrogen atom, a methyl group, a halogen atom or a trifluoromethyl group, and Z represents a hydrogen atom, a fluorine atom, a methyl group or a methoxymethyl group). Pyrethroids such as fluorine-substituted benzyl alcohol ester compounds are representative, but are not limited thereto.

Specific examples of the compound represented by the general formula (I) include 2,3,5,6-tetrafluorobenzyl-chrysanthemate (hereinafter referred to as Compound A), 2,3,5,6-tetra Fluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate (hereinafter referred to as Compound B), 2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- ( 2,2-dichlorovinyl) cyclopropanecarboxylate (hereinafter referred to as Compound C), 4-methyl-2,3,5,6-tetrafluorobenzyl-chrysantemate (hereinafter referred to as Compound D), 4- Methyl-2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate (hereinafter referred to as compound E), 4-methyl-2, , 5,6-tetrafluorobenzyl-2,2-dimethyl-3- (2,2-difluorovinyl) cyclopropanecarboxylate (hereinafter referred to as Compound F), 4-methoxymethyl-2,3,5,6 -Tetrafluorobenzyl-chrysanthemate (hereinafter referred to as compound G), 4-methoxymethyl-2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxy Rate (hereinafter referred to as compound H) or 2,3,4,5,6-pentafluorobenzyl-2,2-dimethyl-3- (2-chloro-2-trifluoromethylvinyl) cyclopropanecarboxylate ( Hereinafter, it is referred to as Compound I). One kind of these compounds may be used, or two or more kinds of compounds may be used in combination. In addition, the compound represented by empentrin and general formula (I) has optical isomers and geometric isomers based on the asymmetric carbon or double bond. Of course, the present invention is also included in the present invention.

In the present invention, a suitable carrier is impregnated with the room temperature volatile insect repellent component. Examples of carriers include cellulose carriers such as paper, pulp, linter, viscose and wood, plastic carriers such as ethylene-vinyl acetate resin and olefin polymer, inorganic carriers such as calcium silicate, sublimable solid carriers, and gels such as carrageenan. The carrier is shaped like a mat or sheet, and has an average outer diameter of, for example, 3 mm to 10 mm, or a substantially granular shape, or a rod shape.

The amount of impregnation of the room temperature volatile insect repellent into the carrier is the material, shape and size of the carrier, the place where the insect repellent is applied (drawer, clothes box, clothes chest, closet, etc.), period of use (6 months, 12 months), etc. May be appropriately determined in consideration of the above. For example, a 12-month insect repellent applied to a 50-liter drawer is about 30 to 120 mg, and a 6-month insect repellent applied to a 600-liter clothes chiff is about 100 to 400 mg.

In the impregnation, if necessary, a solvent such as petroleum, aromatic hydrocarbon or alcohol can be used, and if necessary, a surfactant, a dispersant, a stabilizer, a fragrance, a colorant, an antistatic agent. You may mix | blend an agent etc. suitably. In addition, as long as it does not interfere with the volatilization performance of the room temperature volatile insect repellent component, other highly insecticidal, insect repellent and repellent components (eg, hinokitiol, carvone, safrole, citronellol, cinnamic aldehyde, etc.) Etc.), an acaricide, a disinfectant, a deodorant and the like can be added to form a multipurpose pharmaceutical composition.

In the present invention, such an impregnated carrier is housed in a case or bag to produce an insect repellent, but the specification and form of the insect repellent are not limited at all. For example, a cellulose impregnated mat or sheet is stored in a non-drug-adsorbing plastic case or non-woven fabric molded body provided with volatilization holes, or granular or substantially granular cellulose impregnated beads are used for breathable cellulose. The form accommodated in a system material or a non-woven fabric inner bag can be suitably employed.
Examples of the material of the plastic case include, but are not limited to, polyesters such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyamide (PA), polyacetal, polycarbonate, and methylpentene polymer. Among these, if recycled polyester is used, it is useful from the viewpoint of resource saving, and by adding inorganic substances such as calcium carbonate, magnesium carbonate and titanium oxide to this, it is possible to reduce incineration calories.
Further, it is more convenient if an insect repellent is provided with an indicator function (for example, a discoloration function) indicating the end point of use.

The present invention, as a packaging form for directly encapsulating the insect repellent, is a container composed of a lid and a body that can be opened and closed without being hermetically packaged with a conventional non-breathable plastic bag or aluminum bag, The lid body and the main body are formed of a non-drug-adsorbing plastic, or an insect repellent container having an inner surface laminated with a non-drug-adsorbing plastic film is used.
In other words, in storing room temperature volatile insect repellent components, it has been essential to ensure strict sealing by heat sealing so far, but the present invention overturns this finding and can be opened and closed from the lid and the main body. Even if the container is configured, use an insect repellent container in which the lid and the main body are molded from a non-drug-adsorbing plastic, or the inner surface is laminated with a non-drug-adsorbing plastic film. Thus, it has been found that the loss of the room temperature volatile insect repellent component during long-term storage and distribution can be sufficiently suppressed.

Examples of the material of the drug non-adsorbing plastic or plastic film include polyester (PET, PBT, etc.), polyamide, polyacetal, polycarbonate, polyacrylonitrile, etc. Polyester is preferred from the viewpoint of moldability and availability. Molding into a container is performed by pressing, extruding, or calendaring using the plastic or any plastic material in which the plastic film is laminated on the inner surface (in this case, it may be drug-adsorbing like PP). It can be carried out by a usual method such as inflation, blow molding, injection molding, vacuum molding and the like.

The container for insect repellents of the present invention is opened and closed during use, but usually retainability between the lid and the main body is maintained. Therefore, in order to further enhance the engagement between the lid and the main body, it is a preferred embodiment to attach the following.
(1) The upper surface of the container is formed in a substantially rectangular shape whose four sides are curved outward.
(2) Wrap the lid and main body with a film band. In this case, it may be partially wound or may be shrink-wrapped as a whole.
(3) Spot-sealing the engagement portion between the lid and the main body.
(4) The insect repellent container is further stored in a non-sealing paper box or bag that may have an opening.

The container for insect repellents of the present invention can be placed vertically with the container upper surface facing the front, and can be displayed in stores in any manner of placement or hanging by attaching an appropriate member. For example, if necessary, a hook for store display may be provided on the insect repellent container, or a mount having a hook function may be bonded to the insect repellent container. In addition, the container for insect repellent of the present invention has an advantage that it is easy to handle when storing an unused insect repellent.
According to the insect repellent container of the present invention, the stored insect repellent causes almost no loss of the room temperature volatile insect repellent component during storage. It is possible to efficiently exhibit excellent insect repellent effects against various pests such as. Furthermore, when the indicator function (e.g., discoloration function) indicating the end point of use is linked to the remaining amount of room temperature volatile insect repellent component, for example, discoloration proceeds due to loss of the insect repellent component during storage, and the indicator function during use It can also solve the problem of inaccuracy.

Next, the insect repellent container of the present invention will be described in more detail based on specific examples and test examples.

FIG. 1 shows a perspective view of one embodiment of the insect repellent container of the present invention. A bento box-shaped insect repellent container 1 (vertical approximately 18 cm × horizontal approximately 10 cm × height 7 cm) is composed of a lid 2 made of PET and a main body 3 made of PET. Yes. The upper surface of the lid 2 has a substantially rectangular shape that is slightly curved outward.
FIG. 2 shows a cross-sectional view of an example of the insect repellent 4 used in this embodiment. A pulp mat 5 having a size of 5.1 cm × 2.1 cm and a thickness of 1.0 mm was uniformly impregnated with a chemical solution consisting of 100 mg of empentrin and 15 mg of a paraffinic solvent, and this mat was provided with a volatilization hole 6. An insect repellent 4 for 12 months of use was prepared by storing in a recycled PET plastic case 7. Next, 20 parts of the insect repellent (4) were stored in the insect repellent container 1, and then both parts were wound with a film band 8 in order to improve the attachment between the lid 2 and the main body 3.
When the insect repellent container 1 containing an insect repellent thus obtained was stored in a warehouse for 1 year, it initially retained the impregnated amount of empentrin, and no loss due to volatilization or loss due to adsorption to the container was observed. Also, at the storefront, the lid 2 can be placed vertically with the top surface of the lid 2 facing the front, and variations in display have increased. After the film band 8 was removed at the time of use, the lid body 2 was opened and several insect repellents 4 were taken out, and the rest could be stored with the lid body 2 closed. That is, unlike conventional aluminum bag packaging, once the bag is broken, it is not difficult to ensure sealing performance.

A chemical solution consisting of 150 mg of compound E and 50 mg of paraffinic solvent is prepared by using a pulp-like carrier having a size of 7.8 × 5.8 cm and a thickness of 1.2 mm, and a size of 2.0 × 1.0 cm and a thickness A 1.0 mm indicator mat (a method in which the original coloring fades when the amount is below a predetermined amount in conjunction with the remaining amount of insect repellent components) is impregnated, and these are stored in a PET plastic case to prepare an insect repellent did. The shape of the plastic case is based on the description of Design Registration No. 1033184, with a breathable double-folded hook having a mesh hole, a mat-shaped carrier storage part (12.5 × 7.2 cm), and an indicator mat A storage unit was provided. According to Example 1, a polypropylene material insect repellent container 1 (about 15 cm long × about 10 cm wide × 5 cm high) laminated with polyacrylonitrile having an inner surface of 20 μm thick, and the two insect repellents were prepared. Stowed. In addition, the engagement part between the lid and the main body was spot-sealed at intervals of 1 cm so that both parts were sufficiently attached.
In the insect repellent container containing the insect repellent thus obtained, no loss of insect repellent components was observed in any of the mat-like carrier and the indicator mat during long-term storage. When the insect repellent was taken out from this insect repellent container and suspended in a 800-liter chiffon, it was found that the stored garment was not damaged by clothing pests for about one year. In addition, the amount of the insect repellent component in the indicator mat at the start of use maintained the initial charged value. As a result, the indicator function was accurate, and the fading indicating the end point was not accelerated.

According to Example 1, various insect repellent containers were produced. Insect repellents shown in Table 1 were prepared, and 20 of them were stored in insect repellent containers. Table 2 shows the insecticidal component recovery after storage at 40 ° C for 2 months.

As a result of the test, the insect repellent contained in the insect repellent container of the present invention hardly caused the loss of the room temperature volatile insect repellent component during storage. In addition, as shown in the present invention 3 and the present invention 4, wrapping with a film band or further storing in a small paper box, etc., enhances the attachment between the lid and the main body and further reduces the insecticidal component loss. Since it can prevent further, it was also confirmed that it is a preferable form.
On the other hand, in the conventional packaging method using an aluminum bag using a polyethylene film as a sealant (Comparative Example 1), the adsorption loss of the insect repellent component to the sealant is inevitable. In the case of a container using a plastic film, the same was unsuitable. In addition, as in Comparative Example 2, when an aluminum bag made of polyester is used as the sealant, the adsorption loss of the insect repellent component can be suppressed, but once the bag is broken, it is difficult to ensure the sealing property when storing the unused portion. It was unsatisfactory in terms of convenience, such as being unable to display vertically at the store.

The container for insect repellents of the present invention is useful for effective use of a room temperature volatile insect repellent component, and is excellent in practicality, and thus has high industrial utility.

The perspective view of one Example of the container for insect repellents of this invention is shown. A sectional view of an example of an insect repellent used in the present invention is shown.
