Description

The present invention relates to an improved cylindrical insect repellent diffuser that has a high insect repellent effect and is convenient not only to be placed or hung on a desired place but also to be carried at work.

Conventionally, sheets and nets (nets) containing room temperature volatile (transpiration) insecticidal and insect repellent components (hereinafter sometimes simply referred to as insect repellents) are well known as insect repellent products.

However, such insect repellent sheets and insect nets, particularly insect repellent nets, have a large transpiration area and a high transpiration amount of the insect repellent agent per unit area, so that the insect repellent effect is excellent. May adhere directly to the surface of the human body, which causes a problem in carrying, and there is a problem in using it as a portable device, particularly for carrying it at work.

Insect repellents such as insect repellent sheets and nets are accommodated in resin containers provided with a large number of ventilation holes, or such repellent substrates are sandwiched between reticulated protective sheets that do not contain insect repellents. There is known a chemical diffuser that prevents direct contact of an insect repellent substrate such as a sheet or insect net with the human body, thereby preventing the insect repellent from adhering directly to the human body.

Utility Model Registration No. 3104770

However, it takes time and effort to manufacture and process such a resin container, and it is too bulky, so it is inconvenient to carry, and the drug diffusion area depends on the size of the container. Had the problem of being difficult.

The present invention has been made in view of the problems of the prior art as described above, and can be easily manufactured. The insect repellent is not directly in contact with the human body and can be folded compactly when not in use. It is very convenient, and when it is used, the insecticidal net can be covered on the base material to widen the area to spread the drug, so it has a high insecticidal effect and can be placed or hung on a desired location. In addition, the present invention provides a cylindrical insect-repellent chemical diffuser that is convenient for carrying when working.

The tubular insect repellent diffuser of the present invention is
(1) An insect repellent net containing a room temperature volatile insecticide / insect repellent component is stacked on the inner side, and a protection net containing no insecticide / insect repellent component is placed on the outer surface, and the left and right ends are joined. A cylindrical insect repellent diffusion net comprising a cylindrical multi-layer net, and (2) a plate comprising at least one plate-like support frame having a square planar outer shape and having a central portion perforated. The plate-like support is of a size that can be tightly inserted into the inner surface of the cylindrical insect-repellent drug-dissipating net, and the height of the plate-like support is the insect-repellent agent-diffusing It is characterized by being in the range of 0.5H to 1.5H with respect to the height (H) of the net.

The cylindrical insect repellent diffuser of the present invention can be easily manufactured, and since the protective film serves as the outer surface, the insect repellent contained in the insect repellent net does not directly contact the human body, and is shaped when not in use. However, it is very convenient to carry because the plate-like support is taken out from the cylindrical insect repellent diffusion net or it can be folded compactly without taking it out. By penetrating, it is possible to widen the drug diffusion area, so the insect repellent effect is also high, and there is an effect that it is particularly convenient for carrying at work.

The insect repellent release net 1 according to the present invention has a room temperature volatile insecticide / insect repellent component (hereinafter, sometimes simply referred to as an insect repellent) as an inner surface and a insect net / insect repellent component-free protective net. 3 is formed of a cylindrical multilayer net that is overlapped in a quadrangular shape so as to be an outer surface, and whose left and right or upper and lower ends are coupled.

The insect repellent net 2 in the insect repellent net is a net made of various natural fibers such as cocoons, hemp and wool, various synthetic fibers such as acrylic and polyester, or a blended fiber thereof, and also a thermoplastic resin. Although a net is mentioned, a resin net formed from a thermoplastic resin is particularly preferably used.

Examples of such thermoplastic resins include polyolefin resins such as polyethylene and polypropylene, ethylene-methyl methacrylate copolymers, ethylene-vinyl acetate copolymers, polyamide resins such as nylon, soft polyvinyl chloride resins, polyester resins, acrylic resins, polyethylene terephthalate ( Examples thereof include thermoplastic resins such as PET) resins and olefinic elastomers such as ethylene-propylene-butadiene. The thermoplastic resin here is a general term for such thermoplastic resins and elastomers.

When a thermoplastic resin is used as a raw material, for example, a low-density polyethylene and a high-density polyethylene are appropriately mixed for the purpose of adjusting spinnability and flexibility as a resin net, adjusting the content of insecticidal components and the evaporation rate, etc. The thermoplastic resin may be used as a mixture, for example, by mixing with an olefin resin or by mixing an ethylene-methyl methacrylate copolymer with an olefin resin.

The insect repelling net 2 needs to contain a room temperature volatile insect repellent and any method for incorporating the insect repellent may be used. For example, the insect repellent may be volatile such as acetone, ethanol, ether, etc. Examples of the method include dissolving in an organic solvent such that the concentration is in the range of about 1 to 50% by weight, and impregnating a net made of various base materials produced in advance in this insect repellent solution.

However, in order to stably contain an insect repellent and to evaporate for a long period of time, a thermoplastic resin is used as a raw material, and a predetermined amount of the insect repellent is directly kneaded in advance in the thermoplastic resin, and this is melt-spun. Spinning by the usual method of the above, the obtained insect repellent drug-containing single fiber is knitted as it is, twisted into a yarn and then knitted into a net shape, or the insect repellent drug-containing thermoplastic resin composition A method in which an article is directly formed into a net shape by an extrusion method using a rotary die is preferable.

The thickness of the net of the insect-proof net, the area per mesh (mesh area), the shape of the mesh and the like are not particularly limited and are arbitrary, but generally the thickness of the net yarn constituting the net is 0.01 to about 3 mm, preferably about 0.05 to 1 mm, mesh area network one per 0.5～500Mm ^2, preferably in the range from 5 to 200 mm ^2, the shape of the mesh rectangular, square, such as rhombic Examples include a quadrangle, a hexagon, and a circle.

As insect repellents to be contained in the insect repellent net, those known as room temperature volatile insecticides or insect repellents are applied, and the amount is set as the type of insect repellent component, the type of base material, the shape of the repellent net, and the radiation Generally, it is in the range of 0.5 to 10% by weight as the content in the insect net, although it varies depending on various conditions such as the expected use period.

Examples of the room temperature transpiration insect repellent used for this purpose include, for example, empentrin, transfluthrin, metfurthrin (2,3,5,6-tetrafluoro-4-methoxymethylbenzyl 3- (1-propenyl) -2, 2-dimethylcyclopropanecarboxylate), profluthrin (2,3,5,6-tetrafluoro-4-methylbenzyl 3- (1-propenyl) -2,2-dimethylcyclopropanecarboxylate) Examples include pyrethroid compounds, and among these, metfurthrin, profluthrin, and transfluthrin are preferably used.

The protective net 3 is for preventing a human hand or the like from directly touching the insect repellent net on the inner surface, and the material and manufacturing method of the insect repellent net, except that the insect repellent is not contained. The insect net and protective net are basically the same, and the material, mesh shape, mesh size, mesh thread thickness, etc. may be the same or different, but at least the mesh size of the protective net It is preferable that the size is such that a human finger does not enter for the purpose.

The insect net 2 and the protection net 3 are stacked in a square shape to form a multilayer net in which the protection net 3 is superimposed on the insect net 2.
FIG. 1 shows an example in which the protective net 3 is superimposed on the insect net 2 in the direction of the arrow, but of course there is no problem even if the opposite is true.

Thereafter, the insect repellent net 2 is formed on the inner surface and the protective net 3 is disposed on the outer surface so that the left and right ends of the multilayer net are joined to form an insect repellent drug diffusion net 1 composed of a cylindrical multilayer net as shown in FIG. Is done.
At this time, the insect net 2 and the protection net 3 are preferably the same in length in the lateral direction so that both ends can be combined into a cylindrical shape, but strictly if the connection is possible. It need not be the same length.

Similarly, the height of the insect-proof net and the height of the protection net are usually the same in terms of the length in the vertical direction, but there is no problem even if the protection net is slightly higher than the insect-proof net from the viewpoint of the protection net.
However, the height H of the cylindrical insect repellent agent diffusion net 1 in such a case means the overall height including the protective net.

In addition, when stacking the insect-proof net and the protective net, the nets may be simply stacked so that there is no slack between the faces so that the faces of the two nets are not extremely separated from each other. Alternatively, they may be partially joined in a linear or linear shape by a heat fusion method or an adhesive, or stitched.

The bonding method for the left and right ends of the multilayer net for forming the insect repellent net 1 is not particularly limited, but in order to strengthen the bonding, the end portions are bonded to each other by heat fusion or an adhesive. Or a method by sewing or the like is preferable.
In addition, the insect repellent agent diffusion net is provided with an appropriate pattern by attaching printing or a decorative member to the insect repellent net and / or the protection net to such an extent that the agent dispersal performance is not significantly impaired. It can also be improved.

The cylindrical insect-repellent drug diffusion net 1 composed of such a multilayer net is derived from the net structure and has stretchability as a whole, particularly when the net base material is a thermoplastic resin, as described above. It is suitable for the present invention because it is excellent in the ability to retain a drug and is excellent in the stretchability of the net itself.

The plate-like support 4, which is another constituent member of the cylindrical insect repellent diffuser of the present invention, disperses the insect repellent from the cylindrical insect repellent diffuser net 1 and holds the net in a predetermined shape. And has at least one plate-like support frame 5 with a planar outer shape being quadrangular and having a center portion thereof perforated.

As shown in FIG. 3, the simplest example of the plate-like support body 4 is composed of a single plate-like support frame body 5 having a central portion thereof pierced. Using the stretchability of the cylindrical insect repellent agent diffusion net, a cylindrical insect repellent agent diffuser that is tightly inserted into the inner side surface of the net and whose surface is covered with a protective net is obtained.
In the case where such a plate-like support is composed of a single plate-like support frame, the plate-like support and the plate-like support frame have the same meaning.

The perforated portion 6 of the plate-like support frame serves as a release surface for the insect-repellent agent of the cylindrical insect-repellent agent diffuser, while the width of the frame in the frame portion 7 of the plate-like support frame increases the strength as the plate-like support frame. Therefore, the area and the frame width of the penetrating part are appropriately determined in consideration of the diffusion rate of the insect repellent and the strength of the plate-like support frame.

Similarly, when the thickness of the plate-like support frame is too thin, it depends on the size of the plate-like support, but when it is tightly inserted into the inner side surface of the cylindrical insect repellent drug release net, The plate-like support frame may be bent and the predetermined shape may not be maintained, so that the strength of the plate-like support frame is not bent when the cylindrical insect repellent diffusion net is tightly inserted. A sufficient thickness is required.

Examples of the base material of the plate-like support frame 5 include a metal plate, a plastic sheet, a cardboard, and a wood board, and are not particularly limited. However, polyethylene, polypropylene, and the like are easy to handle, easy to process, and lightweight. A sheet made of a general-purpose thermoplastic resin such as a polyolefin resin such as PET, a polyester resin such as PET, or a polyamide resin such as polyvinyl chloride, polystyrene, or nylon is preferably applied, and these may be transparent depending on the material. It may be opaque or may be pre-colored to improve design properties.

In addition, since the required strength of the plate-shaped support frame varies depending on the strength of the expansion and contraction force of the cylindrical insect-repellent drug diffusing net inserted therethrough, the thickness and frame width of the plate-shaped support frame are the material, tube It also depends on the material of the insect repellent net, the thickness of the threads that make up the net, the net density (number of meshes per unit area), etc. The frame width does not have to be the same around the entire circumference. Depending on the shrinking direction of the insect repellent net, the thickness of the plate-like support frame, the frame width, etc. may be set to the extent that there is no bend based on these various conditions. .

For example, when the cylindrical insect repellent net is made of a general polyolefin fiber and is a polyolefin sheet such as a plate-like support frame polypropylene sheet, the thickness is usually 0.1 mm or more. The upper limit is not particularly limited, but even if it is too thick, there is no particular practical significance, and it is at most about 5 mm.
Further, although the frame width depends on the sheet thickness, the size of the plate-like support frame 5 and the like, generally, since the area of the perforated portion 6 in the plate-like support frame becomes relatively narrow if it is made too large. It is about 3 to 20 mm.

The cylindrical insect repellent diffuser of the present invention is basically composed of the above-described one plate-shaped support frame and a cylindrical insect repellent net, and in use, the cylindrical insect repellent is attached to the plate-shaped support frame. The medicine diffusion net is closely inserted and integrated, and the insect repellent contained in the cylindrical insect repellent net is released from the perforated part of the plate-like support frame, thereby exhibiting its function. become.

Here, the height of the plate-like support frame is preferably about the same as the height H of the cylindrical insect repellent agent diffusion net from the viewpoint of appearance, but the strength of the plate-like support frame member and the tube insect repellent agent diffusion net There is no reason why it must be the same depending on the material and properties of the material, but if it is too short, the upper and / or lower ends of the cylindrical insect repellent agent diffusion net will protrude from the plate-like support frame and free cylindrical insect repellent agent will be released. Since there are many net parts, the shape is not stable, and if it is too long, the exposed surface of the plate-like support frame part will increase and the appearance will be impaired, so it is usually within the range of 0.5 to 1.5H. is there.

The cylindrical insect repellent spreader according to the present invention is composed of the above-described cylindrical insect repellent spread net and a plate-like support composed of at least one plate-like support frame. As shown in FIG. 5, the plate-shaped support frames 5 and 5 ′ are connected to each other with the same outer dimensions, and the connecting portion 8 is a bent side of less than 180, preferably 90 degrees or less, more preferably 45 degrees. A plate-like support body (FIG. 5) bent below is preferably used practically.

Here, in order to bend the two connecting plate-like support frames, a narrow groove-like cut 9 is made at a position corresponding to the bent side, and further cut partially at the center and both ends of the cut. It is also effective to provide a notch and shorten the length of the bent side to make it easier to bend.

In addition, one or a plurality of over-bending prevention protrusions 11 are provided on the frame portion of any one of the plate-like support frames so that the bending angle is adjusted so that the bending angle is not excessively over a desired angle. It is also effective to do.
Such a protrusion 11 may be a rod-shaped, conical or pyramidal protrusion, or a columnar protrusion, and the height of the protrusion may be bent when the tip of the protrusion is the other plate-like support frame. What is necessary is just to be able to prevent the bending beyond the desired angle by contacting the frame portion.

Similarly, in the case where the material of the plate-like support frame is a thermoplastic resin sheet such as a polypropylene sheet, there is a resilience as the material itself, so even if it is bent at the bent side, it will return to its original state. Since the repulsive stress acts, the degree of bending possible can be adjusted by adjusting the depth of the cut.

In the present invention, it is preferable to make a cut so that such a repulsive stress remains even after bending.

The bent plate-shaped support (FIG. 5) is bent in this way, and the inner periphery of the cylindrical insect repellent drug release net is the total outer periphery of the plate-shaped support (plate-shaped support frame). The cylindrical insect repellent net, which is about the same as, preferably slightly shorter than, twice the height H of the body and the sum of the spatial distances between the end edges of the two folded plate-like support frames. The cylindrical insect repellent drug diffusion net is held by two folded plate-like support frames by tightly penetrating the side using the elasticity of the net, and the presence of the plate-like support frame The part of the cylindrical insect repellent that diffuses the part of the part is due to the repulsive force of the folded two plate-like support frames to return to the original state and the stretchability of the tubular insect repellent. Despite the absence of the plate-like support frame, it is tightly pinched and, as a result, shown in FIG. Such cross-section cylindrical insect agents dissipation of the triangle are obtained.

In such a plate-like support frame, a decorative body having an arbitrary shape that may be colored is provided in the penetrating part integrally with the frame part, so that the decorative body is a cylindrical insect repellent net. It is visible from the outside through the mesh and the design is remarkably improved.

A plate-like support including such a decorative body can be obtained by a usual method, for example, at the same time as cutting from a plastic sheet as a substrate.

In addition, since there is too much area occupied by the decorative body in the punched-through portion, the drug sustained release from the cylindrical insect repellent drug release net is blocked by the decorative body and the drug sustained release property is generally reduced. The area ratio of the decorative body in the punched-out portion is 50% or less, preferably about 30% or less.

The plate-like support body in the case where the plate-like support frame body is composed of one or two sheets has been described above. In addition, in the present invention, three or more plate-like support frame bodies having the same or different external dimensions are connected. Further, each connecting portion is bent into a mountain shape, and the outermost sides are in contact with each other, and the cross section with respect to the height can be a square tube shape with a triangle or more.

In this case, when these cylindrical plate-like supports are inserted into the inner side of the cylindrical insect repellent net, in many cases the inner side of the insect repellent net is supported by each plate. The shape is along the frame surface, but depending on the cross-sectional shape and the nature of the insect repellent net, the insect repellent net contacts only a part or all of the plate-like support, In some cases, it does not extend along all the plate-like support frame surfaces.

Further, the cross section with respect to the height is composed of five or more connecting plate-like support frames having the same or different outer dimensions, and each connecting portion is alternately bent in a valley shape, and the outermost sides are in contact with each other. It can also be a star-shaped cylindrical tube.

In this case, the insect repellent agent diffusion net is in contact with only the connecting portions (bent sides) of the plate-like support frame, and the insect repellent agent diffusion net is not in contact with the plate-like support frame between the bent portions. It is in a state that stretched the space

Furthermore, as another aspect, the plate-like support is a cylindrical or elliptical cylinder whose cross section with respect to the height formed by joining both ends of a single square plate-like support frame is circular or elliptical. You can also.

In this case, the upper and lower ends of the cylindrical or elliptical shape are provided with frame portions, but it goes without saying that an arbitrary support frame portion for connecting the upper and lower frame portions is necessary to maintain the shape, In general, two or more such support frame portions are provided, and the intervals are generally equal.

The width of the support frame portion depends on the thickness of the plate-like support, but it is sufficient to obtain the strength necessary to connect the upper and lower ends of the cylindrical or elliptical shape and maintain the shape, If the width is too wide, the sustained release of the drug from the cylindrical insect repellent drug release net is blocked by the support frame portion, and the sustained drug release is reduced.

The cylindrical insect repellent diffuser of the present invention described above can be easily manufactured, and since the protective film is the outer surface, the insect repellent contained in the insect repellent net does not directly contact the human body. Although it depends on the shape, it is very convenient to carry because the plate-like support is taken out from the cylindrical insect repellent diffusion net, or it can be folded compactly without taking it out. Since the drug diffusion area can be increased by penetrating the support body, the insect repellent effect is also high, and it is convenient to carry at work as well as to be placed or hung on the desired place, There is an effect that the range of use is wide.
