Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet insecticide which is effective for controlling fleas, mites and the like, and more particularly to an insecticide sheet which can be cut and pasted into an arbitrary shape.

[0002]

2. Description of the Related Art Conventionally, spray-type and fumigation-type insecticides have been widely used as insecticides for controlling pests such as mites and fleas parasitic on living environments such as carpets, tatami mats and clothing, and animals such as pets. ing. However, these spray-type or fumigation-type insecticides diffuse not only in the place where the pests inhabit, but also in the surrounding area, and thus have a problem of affecting human bodies and animals. In recent years, insecticides with considerably low toxicity have been developed, but the effect of the insecticides diffused in the air on small animals, sickly ill persons, and the like cannot be ignored. On the other hand, insect repellents such as camphor and naphthalene for protecting clothing and the like from pests, and insect repellent sheets obtained by impregnating or applying insect repellent to a base material such as paper are also widely used. These are mainly composed of volatile repellents and have the effect of preventing pests from sticking to clothing etc.
There is no effect of actively exterminating fleas etc. in the habitat.

[0003]

The present invention can be directly applied to places where fleas, ticks and the like inhabit, and is a highly safe sheet-like insecticide in which pesticidal agents are not released to the environment. It is intended to provide an agent. Another object of the present invention is to provide a sheet-like insecticide which can be applied very easily to any place.

[0004]

The insecticidal sheet of the present invention that achieves the above object has a substrate in which a drug layer containing an insecticide and having low tackiness is formed on at least one surface of the substrate. Here, the insecticide means an insecticide that is effective against microorganisms such as fleas and ticks, and includes a wide range of insecticides including miticides. Such an insecticidal sheet can be used by sticking it to any place such as a carpet or a tatami mat or the pet itself by utilizing the weak adhesiveness of the drug layer, and the insecticidal component is volatilized from the drug layer or applied. It exerts an insecticidal effect by penetrating into places. Further, since the drug layer is covered with the base material, there is no possibility that the insecticide will diffuse outside. Therefore, effects on the environment and animals including humans can be minimized. Furthermore, since the drug layer has weak adhesiveness, when the insecticidal sheet is peeled off from the adherend after use, dead insects and the like can also be adsorbed to the drug layer and removed. This also provides an effect of preventing asthma and the like caused by dead mites and the like.
Further, the insecticidal sheet of the present invention has been cut out. As a result, the sheet can be cut into an arbitrary shape, adhered to a size corresponding to a place to be applied. In particular, by making the shape of the cutting process into an animal pattern, application to animals such as pets becomes easy.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing one embodiment of an insecticidal sheet according to the present invention. This insecticidal sheet 10 is composed of a sheet-like base material 1 and a coating layer 2 formed on the base material 1,
The coating layer 2 is formed by applying a coating liquid containing an insecticide and a weak adhesive, and has a weak adhesive property.
The coating layer 2 is preferably provided with a separator 3 that can be easily peeled off. The separator 3 is peeled and removed when the insecticide sheet is used. The separator 3 facilitates storage and handling of the insecticide sheet before use, and also prevents the insecticide from escaping from the coating layer 2.

As the substrate 1, any sheet-like material may be used, and paper, coated paper, cloth, non-woven fabric, or a plastic film such as polyethylene or polyester can be used. Particularly, a flexible material is used. Is preferred. Thereby, it can be easily attached to an uneven place such as an animal body or furniture having a curved surface. When a permeable material such as paper or cloth is used, the coating layer 2
It is preferable to apply a resin coating such as polypropylene or polyethylene on the opposite side. Thereby, it is possible to prevent the medicine from escaping from the surface on the opposite side of the coating layer 2, to enhance the effect of the medicine on the application surface, and to prevent environmental pollution.

On the back surface of the base material 1 (the surface opposite to the surface on which the coating layer 2 is formed), if necessary, characters, patterns and the like are printed, or a sheet on which such printing is performed is laminated. You may.
Thereby, a decorative effect can be given to the insecticide sheet, or information necessary for use, such as a method of use and precautions for use, can be carried on the insecticide sheet itself.

[0008] As the insecticide contained in the coating layer 2, a known chemical having a flea-killing and acaricidal effect can be used. For example, pyrethroid-based insecticides such as fernothrin and fenpropatrin, organic phosphorus-based compounds such as fenitrothion, diphenylcarninol-based compounds such as quercene, and phenyl salicylate are used. The amount of the insecticide contained in the coating layer 2 is not particularly limited, but is 10 to 80 ml / m ² per unit area of the sheet,
More preferably, the content is about 30 to 50 ml / m ² .

As the weak pressure-sensitive adhesive, there can be used known pressure-sensitive adhesives such as rubber-based, acrylic-based, silicone-based and polyvinyl ether-based adhesives used for adhesive tapes, adhesive sheets, double-sided tapes and the like. It is preferable that the adhesive has low tackiness and does not remain on the kimono. The coating layer 2 can be formed by coating the base material 1 with the above-mentioned insecticide and weak adhesive dissolved or dispersed in an appropriate solvent. When the weak pressure-sensitive adhesive is a solventless pressure-sensitive adhesive, a pesticide may be mixed with the pressure-sensitive adhesive composition to obtain a pesticide-containing pressure-sensitive adhesive, which may be coated on the substrate 1. The thickness of the coating layer 2 is not particularly limited, but is usually about 10 to 50 μm, preferably about 20 to 30 μm.

The coating layer 2 may contain, in addition to the insecticide and the weak adhesive described above, additives such as a pigment for adjusting the adhesiveness and a leveling agent, if necessary.

As the separator 3, a paper, a plastic film, or the like, which has been subjected to a release treatment, can be used, and a material having particularly high airtightness is preferable. Thus, even when a volatile chemical is used as the insecticide, the escape of the vaporized gas is prevented, and long-term storage is possible. When the insecticidal sheet is folded or stacked and stored, only one separator 3 may be interposed between the facing coating layers 2.

It is preferable that such an insecticidal sheet has been subjected to a predetermined cutting process at perforations 4 or the like.
The cutting process can be provided, for example, in a lattice shape of 30 cm × 30 cm, so that it can be cut and pasted to a desired size with a minimum unit of 30 cm × 30 cm. In addition, even a large-sized sheet adapted to a fold or a carpet can be easily folded or unfolded, and the perforations 4 provide good adhesion to an adherend.

The cutting may be performed by forming perforations 4 in the shape of an animal pattern as shown in FIG. In the figure, 4 is a perforation along the pattern of the small dog vest, and 4 'is a perforation along the pattern of the medium vest, which are formed concentrically. By cutting out the shape surrounded by a desired perforation, a pattern of the insecticidal sheet 10 suitable for the purpose is obtained, and the insecticidal sheet 10 can be stuck to the body of the animal.

In this case, by printing a pattern corresponding to the pattern on the back surface of the base material 1 of the insecticidal sheet 10, the cutting operation becomes easy, and a decorative effect can be obtained after pasting. Such a pattern-shaped perforation may be formed together with the lattice-shaped perforation described above.

The insecticidal sheet 10 according to the present invention having the above configuration.
Is cut off a portion corresponding to the size or shape of the adherend as needed, then adhered so that the weakly adherent drug layer 2 comes into contact with the adherend, and left for a certain period of time. As a result, the insecticide is vaporized and filled between the adherend and the drug layer 2, or when the insecticide is a contact-type insecticide, the pest directly contacts the insecticide, and It can kill parasites such as mites and fleas that have infested or lived there. On the other hand, since the insecticide is covered with the base material 2, it is not released into the environment, so that a high insecticidal effect can be obtained. In addition, the leaving time after sticking the sheet is not particularly limited, and the effect is usually obtained in several days to several hours, although it varies depending on the application place.

After use, the insecticidal sheet can be easily peeled off from the adherend, and at this time, dead insects can also be peeled off.

In the above embodiment, the case where the coating layer 2 containing an insecticide and a weak adhesive is formed by coating on the surface of the substrate 1 has been described, but the surface of the substrate 1 contains the insecticide. Coating layer 2
May be formed on the coating layer 2 partially, for example, along a cutout line. Since the weak adhesive layer is partially provided, it is possible to secure the contact between the agent of the coating layer 2 and the adhered portion.

When the substrate 1 is made of a material such as paper or cloth into which the coating liquid easily penetrates, the substrate 1 is not coated but is immersed in a solution containing an insecticide to impregnate the substrate 1 with the chemical. May be.
In this case, since the entire substrate also serves as the drug layer, it is preferable that one surface after resin impregnation is coated with a resin in order to prevent the diffusion of the drug from the surface opposite to the sticking surface. Further, it is desirable that the weak adhesive layer is formed partially on the substrate 1 impregnated with the drug, whereby the same effect as that of the insecticidal sheet described above can be obtained without preventing the diffusion of the insecticide by the weak adhesive layer. Can be.

Further, in the above-described embodiment, the case where the drug layer 2 is provided on one surface of the base material 1 has been described, but the drug layer 2 may be provided on both surfaces of the base material 1. Such an insecticidal sheet can obtain an insecticidal effect on both the carpet and the tatami (floor) by being interposed between the carpet and the tatami (floor), for example. It can also function as a fixing member for fixing so as not to shift.

EXAMPLES Examples of the insecticidal sheet of the present invention will be described below. Example After forming perforations on a 90 cm × 90 cm coated paper at 30 cm intervals vertically and horizontally, a coating solution for a drug layer was coated on the uncoated side of the paper so as to have a coating amount of 160 ml / m ^2. Then, a drug layer was formed. The coating solution for the drug layer used was a mixture of 25% by weight of fernotrin in a usual coating solution for an acrylic weak pressure-sensitive adhesive for producing a pressure-sensitive adhesive tape. A separator was laminated on the drug layer to obtain an insecticidal sheet.

After the separator of the insecticidal sheet was peeled off, the drug layer side was stuck to a carpet, left for 24 hours, and the number of mites per unit area before and after sticking was determined. As a result, the number of mites was reduced from 100 to 46, and the insecticidal effect of this insecticidal sheet was confirmed. After peeling, no weak adhesive was observed on the carpet.

[0022]

As is clear from the above examples, the insecticidal sheet of the present invention can be adhered to an arbitrary place by providing a weakly adhesive drug layer on the surface of a sheet-like substrate. Since the insecticidal effect can be obtained, and since there is no emission of the drug into the air, the effect can be maintained for a long time and the influence on the environment can be minimized.

Further, the insecticidal sheet of the present invention can be cut into an arbitrary size and shape by cutting, and can be easily folded or expanded even if it is large in size. It also has good adhesion to the adherend.
