Description

    The present invention relates to an insect repellent material using a room temperature volatile insect repellent compound.

A variety of insect repellents and drug carriers for releasing active ingredients into the air using room temperature volatile insect repellent compounds have been proposed. For example, Japanese Patent Application Laid-Open No. 9-308421 (Patent Document 1) discloses an insect repellent material in which a room-temperature volatile chemical is held in a cylindrical material having many foldable paper holes. Japanese Patent Application Laid-Open No. 10-265303 (Patent Document 2) discloses a drug carrier in which a space is provided inside a three-dimensional structure composed of cell walls such as honeycomb, lattice, and mesh. ing.
JP 9-308421 A Japanese Patent Laid-Open No. 10-265303

  The cylindrical material and the three-dimensional structure have been used in the manufacturing method of “Denguri”, which has been well known as a paper toy and decoration material for a long time, and its applied technology. This is an extremely effective means in that a drug containing an active ingredient can be efficiently released into the air at room temperature without being required. However, since the drug carrier is in an exposed state, the chance of the drug adhering to the hand is increased, which is a problem in terms of drug loss and safety.

As a method for avoiding these problems, Japanese Patent Application Laid-Open No. 11-322504 (Patent Document 3) includes cell walls such as a honeycomb shape, a lattice shape, and a mesh shape formed from a material capable of holding an active ingredient. A multi-dimensional structure having at least two inner and outer layers separated from each other at a predetermined interval is disclosed.
JP-A-11-322504

  A three-dimensional structure disclosed in Japanese Patent Application Laid-Open No. 11-322504 is a protective layer in which an active ingredient is not retained as an outermost layer having a large number of cells composed of cell walls such as a honeycomb shape, a lattice shape, and a mesh shape. By doing so, the chance of the drug adhering to the hand is reduced and the safety is improved.

  However, in the three-dimensional structure of the above publication, there is nothing that protects the outermost layer during use, and there is a possibility that it will be caught by something due to its complicated structure, and it will not necessarily touch the inner layer. Is hard to say. In addition, since the three-dimensional structure is a multi-layer structure and complicated, it is difficult to impregnate or inject the drug, and a complicated manufacturing process is required. In order to make the three-dimensional structure into a predetermined shape, a cutting loss is required. There are many problems to be solved.

  Therefore, an object of the present invention is to solve the problem of the prior art that a drug easily adheres to a hand or the like with a simple structure without taking a complicated three-dimensional structure. That is, an object of the present invention is to provide an inexpensive insect-repellent material that has a low chance of a drug adhering to a hand or the like.

  In addition, in the present invention, anyone can easily suppress the volatilization and promote the volatilization of the room temperature volatile insecticidal compound simply by replacing the way the insect repellent is placed upside down or by removing the moored string. It aims at providing the insect repellent which can be.

  The insect repellent material according to claim 1 of the present invention comprises a foldable columnar material comprising a large number of cells containing a room temperature volatile insecticidal compound and a columnar container having a large number of openings enclosing the columnar material. Insect repellent material, wherein either one of the upper end or the lower end of the columnar material is fixed to the surface of the columnar container, and the other end of the columnar material is provided with means for preventing the columnar material from being folded. It is.

  In the insect repellent material according to claim 2 of the present invention, the upper end of the columnar material is fixed to the top plate surface of the columnar container, and the folding preventing means provided at the lower end of the columnar material has a weight for stretching the columnar material. The insect repellent material according to claim 1, wherein a member is attached to a lower end of the columnar material.

  In the insect repellent material according to claim 3 of the present invention, the lower end of the columnar material is fixed to the bottom plate surface of the columnar container, and the folding preventing means provided at the upper end of the columnar material is laminated with the upper end of the columnar material. It is composed of a plate-shaped material, a string-shaped material that is connected to the plate-shaped body and extends through the hole in the top plate of the columnar container and extends to the outside of the columnar container, and a mooring tool provided outside the columnar container. The insect repellent material according to claim 1.

  That is, one of the insect repellents of the present invention promotes the volatilization of the insect repellent compound contained from the surface of each cell of the columnar material when placed normally so that the top plate of the columnar container is on top. When the top plate is turned upside down, a foldable columnar material composed of a large number of cells is folded and the volatilization of the insecticidal compound is suppressed. Another insect repellent material is that when the columnar material is stretched by the string, the volatilization of the insect repellent compound contained in each cell of the columnar material is promoted, and when the string stretching is stopped, the columnar material is folded and the insect repellent It is an insect repellent that suppresses the volatilization of volatile compounds.

  According to the present invention, the columnar material is stretched or folded by simply replacing the top of the insect repellent or pulling or loosening the string, facilitating the promotion of volatilization of the room temperature volatile insecticidal compound and It is possible to switch the suppression, and an insecticide excellent in convenience is provided. In addition, it is easy to inject insect repellent compounds (hereinafter sometimes simply referred to as “drugs”) into the columnar material, reducing the chance of the insect repellent compounds adhering to the hands etc. without taking a complicated structure. An insect repellent with improved properties is provided.

As the room temperature volatile insect repellent compound used in the present invention, a compound having a vapor pressure at 25 ° C. of 1.0 × 10 ⁻⁶ mmHg or more is preferable, and a vapor pressure at 25 ° C. is usually 1.0 × 10 ^−6. Empentrin, transfluthrin, 1-ethynyl-2-fluoro-2-pentenyl 3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxy in the range of ~ 5.0 × 10 ⁻² mmHg 1-ethynyl-2-methyl-2-pentenyl 3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate, 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl 3- (1-propenyl) -2,2-dimethylcyclopropanecarboxylate, 2,3,5,6-tetrafluoro-4-methyl Insecticides typified by room temperature volatile pyrethroid compounds such as benzyl 3- (1-propenyl) -2,2-dimethylcyclopropanecarboxylate, N, N-diethyl-m-toluamide, caran-3,4-diol Pest repellent compounds such as 1-methylpropyl 2- (2-hydroxyethyl) -1-piperidinecarboxylate are used.

  As the columnar member made of a large number of foldable cells used in the present invention, as described above, what is called “Denguri” and known as a paper toy or decoration can be used. It is obtained by laminating and integrating a large number of porous sheets on each sheet alternately by half a pitch and applying and bonding an adhesive in a linear form, and then cutting or hollowing into a predetermined shape. When the uppermost and lowermost porous sheets are linearly stretched in opposite directions, a large number of cells are formed. In English, it is called “honeycomb tissue decoration” because the spread as shown in FIG. 3 looks like a beehive. In addition, the feature of dengue is that it returns to the original form which is a normal laminated body when it stops stretching or spreading.

  The above examples can be expanded into a fan shape formed by swinging 180 ° about one side of one end face as shown in FIGS. 2 and 3, or a columnar shape or a spherical shape (not shown) further rotated 360 °. It is generally used as a decoration or a toy.

  However, the collapsible columnar material composed of a large number of cells in the present invention linearly stretches the uppermost layer and the lowermost porous sheet in opposite directions so that a large number of cells as shown in FIG. It is preferable to use it so as to be formed almost uniformly. When stretched into a fan shape with the side of one end face as an axis as shown in FIGS. 2 and 3, in the case of FIG. 2, the cells near the center of the fan shape become smaller and the cells at the outer edge portion become larger. Therefore, it is not preferable because the volatilization of the insect-repellent compound occurs, and in the case shown in FIG. 3, a relatively uniform cell is formed and looks good, but each cell has an opening on only one side and is poorly ventilated. It is not an efficient form for volatilization of compounds. However, as shown in FIG. 1, the stretched columnar material forms uniform cells as a whole, and the volatilization of the room temperature volatile insecticide compound is uniform and the wind is good, so it is distributed inside the columnar material. It is preferable because an effective insect repellent effect is obtained without causing bias in the insect repellent compound. It should be noted that the columnar material of the present invention in which the method for producing dengue is used will naturally return to the original form of a normal laminated body when stretching is stopped. It is stretched when is applied, and when it is removed, it is folded and contracts until it looks like the original laminate.

The porous sheet used for the columnar material in the insect repellent material of the present invention includes paper materials such as paperboard, filter paper, synthetic fiber mixed paper and the like, nonwoven fabrics, felted fabrics, inorganic fiber sheets, plastic porous materials, etc. It is possible to transfer the remaining liquid sequentially according to the volatilization state of the room temperature volatile insecticidal compound, and use a chemically inert substance for the room temperature volatile insecticidal compound contained. In the case of a porous sheet made of a paper material, the basis weight is preferably 10 to 70 g / m ² . When the basis weight is lower than 10 g / m ² , the strength of the paper is insufficient, and when the basis weight is higher than 70 g / m ² , the rigidity of the paper becomes too high, which is not preferable. So-called thin paper having a basis weight of about 20 g / m ² is most preferably used from the viewpoint of easy formation of cells, stretching and folding.

  The present invention assumes an insect repellent material that can be used for about three months, and the columnar material described above is also preferable in that stretching and folding are repeated every day. The pitch for applying the linear adhesive is not particularly limited, and the pitch may be the same or different. In addition, since the pitch is related to the size of the cell when stretched, it can be appropriately selected in consideration of the method of using insect repellents such as the volatilization rate and volatilization amount of the drug, and also the design, and the pitch is 5 to 30 mm. Is preferred. The size of the cell formed from a pitch of 15 to 30 mm is one of the preferred embodiments because the insect repellent compound is easily and efficiently volatilized and is excellent in aesthetics.

  As a foldable columnar material consisting of a large number of cells of the present invention, usually a large number of porous sheets coated with an adhesive in the form of a line at the same pitch are laminated together by alternately adhering to each of them by a half pitch. However, the present invention is not necessarily limited to this. For example, an aspect in which the pitch of the upper half and the lower half of the columnar material is different, and an aspect in which the upper half and the lower half of the columnar material are crossed in the direction of the applied adhesive line are also possible. include. The shape of the porous sheet is not particularly limited as long as the circular shape is somewhat excellent due to smoothness of stretching and folding, but may be a quadrilateral, hexagonal, circular, star shape, or other designable shape. In addition, many porous sheets may have the same shape or different shapes.

In order to explain the present invention, a production procedure is described below, but the present invention is not particularly limited to this method. First, an adhesive is linearly applied to one porous sheet at the same pitch, that is, at a certain distance. The porous sheet surface to which the adhesive is applied may be one side. Prepare another porous sheet coated with adhesive, and shift the non-adhesive surface of the second porous sheet by shifting the linear adhesive by a half pitch to the adhesive surface of the first porous sheet. Superimpose and bond. The linear adhesive is applied in the same direction (parallel) without crossing, and the adhesive application direction of the sheets to be overlapped is also applied in the same direction (parallel) as the underlying sheet. The third sheet is returned by a half pitch so that it is at the same position as the first sheet, and the fourth sheet is shifted by a half pitch so that it is at the same position as the second sheet. Glue up to the number of sheets. When the predetermined number of sheets is reached, the porous sheets not coated with the adhesive are stacked and bonded. For example, a laminate composed of 52 sheets of about 20 g / m ² thin paper, with a glue pitch of 20 mm, cut into 65 mm × 65 mm and used as a columnar material, and a predetermined amount of a normal room temperature volatile insect repellent compound The contained insect repellent material can satisfy the required volatilization amount of the active ingredient between 6 mats.

  The laminate produced by the above procedure appears to be a simple laminate of porous sheets while being folded unless stretched. When the uppermost layer and the lowermost layer porous sheet are linearly stretched in opposite directions, a large number of uniform cells are formed as shown in FIG. 1, and a foldable columnar material consisting of a large number of cells is formed. . For the convenience of explaining the present invention, regarding the columnar material, the stretched state is also referred to as an elongated columnar material, and the folded state is also referred to as a folded columnar body.

  As long as the columnar container used for the insect repellent material of the present invention can contain the elongated columnar material, its horizontal cross-sectional shape is not particularly limited, and may be a quadrangular column, a hexagonal column, a cylinder, or the like. it can. The columnar material may have a shape different from that of the columnar material as long as the expanded columnar material does not touch the side wall surface of the columnar container and the columnar material can be folded. However, with respect to the height, it is preferable that the columnar material is stretched almost evenly when the encapsulated columnar material is stretched to the full height of the columnar container. When the gap between the porous sheets is not stretched and the cells remain without being opened, the load on the porous sheet and its bonded portion is the smallest and the possibility of destroying the columnar material is reduced.

The material of the columnar container is not particularly limited, such as paper such as paperboard, molded plastic, and metal such as a wire mesh. In the case of paper, a paperboard having a basis weight of 300 to 1,000 g / m ² is preferably used in terms of strength, waist (rigidity), ease of processing, and production cost. In addition, a paper container is preferable because it has less environmental impact than other materials in terms of disposal and can be easily recycled. It is also preferable in that the loss of the insect repellent compound is small because adsorption that impairs the volatilization of the insect repellent compound is difficult to occur as in certain types of plastics.

  The shape and number of the many openings provided in the columnar container are not particularly limited, and are not particularly limited as long as they do not hinder the volatilization of the drug and the diffusion out of the container. It may be a figure. The size such as the slit width and the circle diameter may be 3 to 15 mm, and a width of 5 to 12 mm is particularly preferable because it is difficult for a finger or the like to enter the columnar container.

  The columnar container preferably has a shape that can be easily assembled. For example, the development shown in FIG. 4 is a preferred example of a paper columnar container. The developed view of FIG. 4 shows the insertion type at the top and bottom, but in addition to this, the so-called hell bottom type in which the bottom is integrated and the one-touch pasting type in which the bottom is assembled when raised Is preferable as a paper columnar container that can be easily assembled. It is preferable that the columnar container has a shape that can be easily assembled because the columnar container can be provided to consumers together with the columnar material folded in a state before assembly.

  The method of fixing the upper end or lower end of the columnar material to the columnar container is not particularly limited as long as the columnar material does not come off from the fixing surface of the columnar container in use, and can be fixed with a double-sided adhesive tape or glue. It is.

In the insect repellent material of the present invention, the means for preventing the folding of the columnar material provided at the end of the columnar material not fixed to the columnar container is different between the aspect of claim 2 and the aspect of claim 3. The aspect of Item 2 will be described specifically with reference to the drawings, using examples. That is, as the member having the upper end of the columnar material fixed to the top plate surface of the columnar container and having a weight for stretching the columnar material attached to the lower end of the columnar material, paper such as paperboard is more preferable. It may be made of plastic or metal. When using paperboard or the like, it may be a laminate of a plurality of sheets. For example, the tissue paper having a basis weight of 20 g / ^{m 2} to the columnar member created by superimposing 52 sheets at a pitch 20 mm, when using a paperboard having a basis weight of 600~1,200g / ^{m 2} as the member, the member columnar container It was confirmed that it was suitable as a member having a weight to stretch the columnar material. The shape of the member may be a plate shape, a ring shape or a frame shape, and may be the same as or different from the shape of the porous sheet constituting the columnar material. If the shape is the same, the size is preferably the same or slightly larger, and if the shape is different, the size is preferably slightly larger.

  In the insect repellent material according to the aspect of claim 2, when the columnar material folded by some means such as a fastener is removed so as not to be stretched to the top plate of the columnar container, the weight attached to the lower end of the columnar material is removed. The folded columnar material is stretched so that the member having the columnar container moves by free fall to the bottom plate surface side of the columnar container, and the cells of the columnar material are in a state of being almost evenly opened and contained as shown in FIG. Volatilization area of insect repellent compounds is greatly increased and volatilization is promoted. On the other hand, when the insect repellent material is turned over and the top plate is turned down, the member moves to the top plate surface side, the columnar material is folded into a state as shown in FIG. 6, the volatilization area is drastically reduced, and volatilization is suppressed. Is done. That is, it is possible to control the volatilization of the room temperature volatile insecticidal compound that easily volatilizes from the columnar material simply by replacing the top and bottom surfaces of the columnar container of the insecticidal material so that they are upside down.

  Therefore, 1 to several insect repellents according to the aspect of claim 2 are installed in a suitable indoor location such as a residence, office, warehouse, etc. with the top surface of the columnar container facing upward, Used to control In use, when the top plate surface of the insect repellent material of the present invention is turned up, the columnar material is stretched to promote the volatilization of the room temperature volatile insect repellent compound and function as an insect repellent material. When not used, when the insect repellent material is turned upside down, the columnar material is folded and the volatilization of the insect repellent compound can be suppressed. Therefore, the insect repellent effect can be maintained for a long time with a simple operation that anyone can do.

  Next, although an Example demonstrates in detail, the aspect of Claim 2 of this invention is not limited to the following examples.

Example 1 is shown in FIG. 1 as an example of the columnar material of the present invention. A method for producing the columnar member 1 shown in FIG. 1 will be described below. A 20 g / m ² thin paper was used as the porous sheet 2 and a 20 mm pitch, that is, a distance of 20 mm was separated and an adhesive was applied in a line shape having a width of about 2 mm. Next, apply the same adhesive to the other same thin paper, and shift the linear adhesive to the adhesive application surface of the first thin paper by a half pitch (10 mm). The non-adhesive of the second thin paper The surfaces were overlapped and adhered. Similarly, up to 51 sheets were laminated and bonded to the thin paper to be stacked one by one while shifting by a half pitch (10 mm). Finally, a laminate obtained by laminating thin papers without adhesive applied and trimmed to individual sizes of 65 mm × 65 mm was stretched with both hands, as shown in FIG. A large number of cells formed by the porous sheet 2 are in an open state, and it was confirmed that they can be used as the foldable columnar material 1 composed of a large number of cells of the present invention.

As a member 4 having a weight for stretching the columnar material, an 800 g / m ² paperboard having a size of 65 mm × 65 mm was adhered to the one end surface of the columnar material 1 in accordance with the shape of the thin paper with a double-sided adhesive tape.

  The columnar material 1 has 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl (1R) -trans-3- (1-propenyl (Z / E = 8 / 1))-2,2-dimethylcyclopropanecarboxylate (Pyrethroid compound manufactured by Sumitomo Chemical Co., Ltd., trade name: Eminence) was used in an amount of 300 mg in a folded state.

Next, a columnar container 5 having a top plate 10 and a bottom plate 11 having a square shape of 89 mm × 89 mm, a height of 160 mm, and 16 slit-shaped openings 9 was prepared. The columnar container 5 was punched out of cardboard having a basis weight of 350 g / m ² according to the development shown in FIG. A broken line shows the bending part, the paste part 6, the top plate, and the insertion part 7 of a bottom plate. The convex part 8 in FIG. 4 is a part that becomes a leg of the insect repellent material when the top plate and the bottom plate are assembled into the square columnar container 5, and is effective for stably installing the insect repellent material in a balanced manner.

  Next, after attaching the member 4 to one porous sheet surface of the columnar material 1 and fixing the plate material of the other porous sheet surface to the top plate 10 with a double-sided adhesive tape, the columnar material 1 is not stretched. After applying the paper strip as described above, the assembling work was proceeded in the order of bending, pasting, and insertion, and the insect repellent material of Example 1 was produced. A developed view before assembly is shown in FIG. Although this insect repellent can be provided in an assembled state, since it is a structure that anyone can easily assemble with a simple operation, the compact before assembly or during assembly as shown in FIGS. 10 and 11 It can be provided at a stage where it can be in good condition and is excellent in terms of logistics and storage. Since the columnar material 1 needs to be folded until just before the start of use, the columnar material is used together with the member 4 by a method other than the removable paper belt shown in FIG. 10, for example, a stretch prevention means such as a rubber band or an insertion tool. It is more preferable that 1 is fixed to the top plate 10 so as not to be stretched. At the start of use of the insect repellent material, these fasteners are removed, and the folded columnar material 1 is stretched and used.

  5 to 9 show usage examples of the insect repellent material of the present invention. FIG. 5 shows the state of the insect repellent material when the top plate is on the upper side, and FIG. In FIGS. 5 and 6, portions that cannot be seen from the outside inside the columnar container are indicated by dotted lines. 7 to 9 are schematic diagrams of the inside of the insect repellent material, and show the columnar material 1 and the top plate 10 (dotted line) of the columnar container 5. The folded columnar material 1 before the start of use is covered with a paper band 12 so that the member 4 is not dropped and stretched (FIG. 7). When the paper strip 12 that fixes the columnar material 1 is removed, the member 4 falls in the direction of the bottom plate 11 (FIG. 8). Finally, the member 4 reaches the bottom plate 11, and the columnar material 1 is stretched and opened. It becomes the columnar material 1 which consists of the cell 3 (FIG. 9).

  Therefore, as shown in FIG. 5, when the top plate 10 is turned up, the columnar member 1 is maintained in a state in which many cells 3 are opened. On the other hand, when the top plate 10 is lowered as shown in FIG. 6, the member 4 is dropped in the direction of the top plate 10, so that the columnar material 1 is folded and apparently thin paper sheets are laminated.

  In other words, the user can control the volatilization of the room temperature volatile insect-repellent compound that is easily volatilized from the columnar material simply by changing the placement of the insect-repellent material. It is used as an insect repellent material for control. When not used, when the insect repellent material is turned over, the columnar material is folded and the volatilization of the insect repellent compound can be suppressed.

  Also, in this example, almost all of the columnar materials and columnar containers constituting the insect repellent material are manufactured mainly from paper, and even when all the insect repellent compounds are volatilized and used, the insect repellent material is discarded. The load is low, and it can be recycled into papermaking materials.

Next, the aspect of Claim 3 of this invention is demonstrated concretely. That is, the lower end of the columnar member is fixed to the bottom plate surface of the columnar container, and the folding preventing means provided at the upper end of the columnar member includes the plate member 15 laminated on the upper end of the columnar member 1 and its plate shape. A string-like material 13 connected to the body 15 and extending through the hole in the top plate 10 of the columnar container and extending to the outside of the columnar container, and a mooring tool 14 provided outside the columnar container. The plate-like material 15 is made of a relatively thin paperboard of 300 to 500 g / m ² because it is sufficient if the columnar material 1 has a waist (rigidity) sufficient to maintain a flat surface when the columnar material 1 is stretched by the string-like material 13. Use. The string-like material 13 can be used without any particular limitation as long as plant fibers or synthetic fibers are twisted. The length of the string-like material 13 is longer than at least the height of the columnar container, one end is connected and integrated with the plate-like material 15 fixed to the upper end of the columnar material 1, and the columnar container starts from the upper end of the folded columnar material 1. When the return prevention tool which does not pass the hole of the top plate 10 of a columnar container is provided between the mooring part 14 provided in the other end from the part which penetrated the hole of the top plate 10 and reached the exterior of the columnar container preferable. The mooring portion provided at the other end of the string-like material is not limited in its shape, and a hook or ring-like plastic or metal is preferably used. It is also a preferable example that the ring formed by folding the other end of the string-like material is a mooring tool. Further, these mooring tools may also serve as a return prevention tool.

  Next, although an Example demonstrates in detail, the aspect of Claim 3 of this invention is not limited to the following examples.

  Example 2 is shown in FIGS. 12 and 13 as an example of the columnar material of the present invention. The columnar material of Example 2 can be the same as that of Example 1 as it is. However, the upper end of the columnar material was laminated and integrated with a plate-like material from which the string-like material connected from the opposite surface extends. Since the columnar container is almost the same as the developed view of FIG. 4 and is omitted, a relatively small diameter hole through which the string-like material 13 penetrates is provided at the center of the top plate 10 of the developed view of FIG. 11, the lower end of the columnar material having the string-like material laminated on the upper end was fixed with a double-sided adhesive tape, and preparation for starting the assembly of the insect repellent material of Example 2 was completed. The process up to bending and pasting proceeded in the same way as in Example 1, but after inserting the end of the string-like material 13 extending from the upper end of the columnar material 1 through the hole in the center of the top plate of the columnar container before insertion. Insertion was performed, and the end of the string-like material 13 extending outside from the hole of the top plate 10 after assembly was folded back to form a knot ring 14 as the anchoring portion 14, thereby completing the insect repellent material of Example 2.

  The state before use of the insect repellent material of Example 2 is shown in FIG. The columnar material 1 is folded, and the volatilization of the contained drug is suppressed. The ring (the mooring portion 14) at the end of the string-like material 13 extending from the insect-repellent top plate 10 was hooked on the hook hanging from the ceiling and suspended in the air to start use. Due to its weight, the columnar container was lowered by the same length as the height of the columnar container and stopped. Therefore, the upper end of the columnar member 1 was pulled up to the upper end of the columnar container, and it was confirmed that each cell was open. This state is shown in FIG. The columnar material 1 is stretched, and the volatilization of the contained drug is promoted. When the suspended insect repellent material is removed from the hook, most of the string-like material 13 extending long outside the container is drawn into the container, and the columnar material 1 is folded. It was confirmed that the volatilization of was suppressed. Although the insect repellent material of Example 2 was placed on a table, the string-shaped material was pulled upward to stretch the columnar material, and the string-shaped material was left as it was without moving using a clothespin as a back-preventing tool. The columnar material remained stretched. When the clothespin was removed, most of the string-like material was drawn into the container, and the columnar material was folded.

  Also in the insect repellent material of Example 2, the user can easily control the volatilization of the room temperature volatilizing insect repellent compound that volatilizes from the columnar material simply by suspending or removing the insect repellent material, and the columnar material 1 is stretched. It was confirmed that it was used as an insect repellent for controlling mosquitoes, spiders, etc. with the cell open.
