Description

The present invention relates to a sheet-like mosquito coil and a method for producing the same. Specifically, the present invention relates to a mosquito coil that has been made from a conventional mosquito coil component in a flexible sheet.
Therefore, the field of use of the present invention relates to the field of manufacture and use of mosquito coils.

  In the past, mosquito coils have been used to make uniform insecticide active ingredients such as pyrethrin and allethrin, pesticide chrysanthemum stalk powder, pesticide chrysanthemum extract powder, woody flour and other vegetable dust base materials, pastes, pigments and pigments. It is manufactured by mixing, adding water and kneading, followed by molding and drying. In the above plant-based dust base, the insecticide chrysanthemum extract powder and insecticide chrysanthemum stem powder are indispensable as a combustion aid for creating a texture unique to mosquito coils and burning them at an appropriate rate.

In recent years, there are few opportunities to use mosquito coils in urban areas due to living environment improvements and the use of other drugs, but they are still indispensable for living in the suburbs or mountains. In particular, it is indispensable as a simple and effective insect avoidance material when camping on mountainous areas or beaches where pesticides that are electrically heated and volatilized cannot be used.
However, the conventional mosquito coil has a certain thickness and is bulky, and is fragile and easily broken. Therefore, in the present application, an attempt is made to realize a mosquito-repelling incense that is sheet-like and flexible and maintains its medicinal effect.

Prior art also exists for sheet-like mosquito coils. For example, Patent Document 1 relates to “mosquito remnant incense”, but has proposed a method in which several sheets of paper are pasted together with a paste containing an anthelmintic agent and cut into an incense stick. However, such a manufacturing method is considered to be extremely troublesome.
Patent Document 2 proposes a pest repellent paper obtained by applying or impregnating a mugwort extract or dokudami extract to paper, but when such paper is used by burning, an appropriate burning rate cannot be obtained. it is conceivable that.

Patent Document 3 proposes a flammable insect repellent that is a paper base material. However, this is basically to produce a paperboard strip as a support and coat the strip with an insect repellent. Therefore, it is considered difficult to produce mosquito coils with the scent, color and feel of insecticides and cedars that have been passed down in Japan for a long time.
Patent Document 4 proposes “scented paper and paper products”. The main purpose of the scent is to mix agarwood or sandalwood fine powder into the papermaking material and make it together, and the purpose is different from that of the present application.
Moreover, it is described in patent document 5, patent document 6, etc. about macroencapsulating insecticide components, such as a pyrethrin and an allethrin.

  Therefore, in the present invention, the mosquito coil has a sheet-like form, and the mosquito coil insecticide component and paper fiber are added or made in one piece. .

  The first of the gist of the present invention is a sheet-like product characterized by spraying or impregnating an insecticide active ingredient on a sheet-like material obtained by integrally paper-making and drying a mosquito coil incense burner plant and other plant fibers. In mosquito coils.

  The second of the gist of the present invention is a sheet-like mosquito coil, characterized in that a mosquito coil incense burner plant, other plant fibers, and a microencapsulated insecticide active ingredient are paper-made and dried. .

  According to the third aspect of the present invention, a mosquito coil incense burner plant and other plant fibers are made in one piece, dried into a sheet, sprayed or impregnated with an insecticide active ingredient, and then applied to the sheet. The sheet-like mosquito coil is characterized by having a perforation line or a half-cut line in a spiral shape or a zigzag shape so as to form a continuous combustion path.

  According to the fourth aspect of the present invention, a mosquito coil incense burner plant, other plant fibers, and a microencapsulated insecticide active ingredient are made into a sheet after being made into paper, and dried into a sheet. The sheet-like mosquito coil is characterized by having a perforation line or a half-cut line in a spiral shape or a zigzag shape so as to form a continuous combustion path.

  The fifth aspect of the present invention is a sheet-like mosquito coil, characterized in that a mosquito coil incense burner plant and other plant fibers are mixed, paper-made together and dried, and then sprayed or impregnated with an insecticide active ingredient. In the manufacturing method.

  Sixth of the gist of the present invention is a sheet-like mosquito coil, characterized by mixing a mosquito coil incense burner plant, other plant fiber, and an active ingredient of microencapsulated insecticide, papermaking and drying. Manufacturing method.

(1) Since the sheet-like mosquito coil of claim 1 or 2 is rich in flexibility, it can be bent, printed, foil-pressed, perforated, half-cut, etc. Is easy.
(2) In the embodiment of claim 2 or claim 4 containing the microencapsulated insecticide component, the persistence of the insecticide component can be increased.
(3) In the embodiment of claim 3 or claim 4, in which the perforated line or the half-cut line is inserted in a spiral shape or a zigzag shape so that the sheet-like mosquito coil is formed as a continuous combustion path, Can be used as a mosquito-repellent incense immediately after separation.
(4) The manufacturing method according to claims 6 and 7 is characterized in that the mosquito coil can be manufactured in the paper making process without molding or extruding.

As described above, conventional mosquito coils are generally used as insecticide active ingredients such as pyrethrin and allethrin as insecticide chrysanthemum stalk powder, pesticide chrysanthemum extract powder, vegetable powder base materials such as wood powder, glue and pigments, It is manufactured by mixing pigments and the like uniformly, adding water, kneading, molding into a flat plate shape, die cutting, and drying. The reason for being limited to such processing steps is that the paper making process was considered difficult with the conventional composition.
Therefore, in the present invention, paying attention to the paper making of the flame retardant plant with flexible plant fiber and spraying the insecticide component, or paper making the microencapsulated insecticide component together with the plant fiber, It is a thin sheet-shaped mosquito coil.

  FIG. 1 is a manufacturing process diagram of the first form of the sheet-like mosquito coil, FIG. 2 is a manufacturing process diagram of the second form of the sheet-like mosquito coil, and FIG. 3 is a perforated line or a half-cut line spirally to the sheet-like mosquito coil. FIG. 4 is a diagram showing a state where the sheet-like mosquito coil has been inserted and a perforation line or a half-cut line is inserted in a folded shape.

  As shown in FIG. 1, a sheet-like mosquito coil incense stick 1 according to the first embodiment is made by paper-making a mosquito coil incense burner plant 11 and another plant fiber 12, preferably a Japanese paper raw material, and drying. However, about several to 10% of moisture is left. After drying, spraying or impregnation with the insecticide active ingredient is followed by pressing if necessary. The plant fiber 12 preferably contains at least one kind of Japanese paper raw material. This is because the flexibility of the sheet-like mosquito coil is increased.

As shown in FIG. 2, the sheet-like mosquito coil 2 of the second form is made by paper-making the mosquito coil incense burner plant 11, the plant fiber 12, and the microencapsulated insecticide active ingredient 21 together and drying. After drying, press if necessary.
In both the first form and the second form, the thickness of the sheet after drying is finished to a thickness between 500 μm and 1000 μm. More preferably, the thickness is 700 μm to 900 μm. This is because by setting the thickness to such a degree, the flexibility is well broken, cracking, post-processability is excellent, and there is no problem in terms of combustibility. In the vicinity of a thickness of 800 μm, the rice tsubo is about 120 g / m ² .

The mosquito-repellent incense burner plant 11 is a material mainly composed of pesticide-extracted chrysanthemum extract powder, stem powder, wood powder, cedar and tea foliage powder, tab foliage powder, and the like. Insecticidal chrysanthemum-extracted cocoon powder and stem powder have an insecticide medicinal effect and a scent peculiar to a mosquito coil. Cedar foliage powder is also well known as an incense scent component. JP-A-56-2058 uses corn core powder, JP-A-58-99401 uses cocoa husk powder, cinnamon leaf powder, tarragon extract powder, In Japanese Patent No. 308512, orange peel is used, and in Japanese Patent Publication No. 60-58201, coffee bean husk is used, but these may be used together.
When making paper, these plant fibers are mixed and chopped for use. However, since they are crushed by a pulper, the thickness and length of the raw material itself are not particularly problematic.

In addition to the above, if necessary, pigments, pigments, pastes and fungicides are added. Mosquito green is used as a pigment, water-soluble cellulose, CMC, PVA, constitutive and the like as a paste, and dehydroacetic acid as a fungicide.
As an example, the composition of the mosquito coil incense burner plant 11 can be about 30-50% pesticide extracted chrysanthemum powder, 15-20% wood flour, 10% cedar flour, and about 10-15% pig flour. However, the present invention is not limited to this.
In principle, the mosquito-repellent incense burner plant 11 is collected and used as described above, but a commercially available mosquito-repellent incense can be purchased and pulverized as soon as possible. In this case, the plant fiber is crushed to about 20 μm to 500 μm in length and thickness, and mixed with other plant fibers, particularly Japanese paper raw material, to make paper. However, since the insecticide component is washed away in the paper making process, it must be added again.

As a Japanese paper raw material, wood-based bast fibers such as cocoons, cocoons, and husks are used as is well known. The cocoon fibers are long and strong, with a fiber length of about 10 to 15 mm, and are suitable for paper. The fibers of the three bases and the husks have a fiber length of about 5 mm. Bamboo fibers are sometimes used.
In the case of husk, soak the husk in water and add alkali to boil. After that, the raw material is beaten with a beater and passed through a screen to obtain one paper fiber at a time.
By adding these Japanese paper raw materials, flexible and flexible sheet characteristics can be obtained. The paper-making method may be manual or mechanical. In the case of Japanese paper raw material, the ratio with the mosquito coil incense burner plant 11 is about 1: 9. Instead of the Japanese paper raw material, or together with the Japanese paper raw material, a general pulp material or other vegetable fiber may be used.

  As the microencapsulated insecticide active ingredient 21, a macroencapsulated insecticide ingredient such as natural pyrethrin or allethrin is used. Natural pyrethrin is an insecticide and a powerful insecticide. It is known that both natural pyrethrin and allethrin are fast-acting, but human animals and plants have almost no toxicity. However, there is a problem with fish poison, but it can be alleviated by microencapsulation. Natural pyrethrin is a lipophilic substance that is liquid at room temperature and contains pyrethrin 1, pyrethrin 2, cineline 1, cinerin 2, jasmorin 1, and jasmolin 2. Allethrin is a mixture of eight isomers but is also a lipophilic substance. Although natural pyrethrin or allethrin itself can be microencapsulated, it is usually used by mixing with a compatible solvent.

Examples of the film material of the microcapsule include starch, polyurethane, polyurea, polyamide, polyester, polycarbonate, and the like. Starch, polyurethane, and polyurea are preferable, and starch is particularly preferable. This is because starch dissolves in water, does not easily flow out due to the difference in specific gravity, and is easily entangled with fibers.
The average particle size of the microcapsules is preferably 5 μm or more and 100 μm or less. This is because the medicinal effect cannot be sufficiently exerted when the thickness is less than 5 μm. The content in the microencapsulated insecticide composition is usually said to be 1 to 40%. The additive of the active ingredient in the microcapsule with respect to the mass of the plant fiber may be in the range of 0.5 to several percent.

In the first embodiment, when spraying or impregnating the pesticide active ingredient, a solvent for dissolving pyrethrin or allethrin, such as dimethylbenzene, dodecylbenzene, butylhydroxytoluene, liquid paraffin, kerosene, cottonseed oil, castor oil, large Dissolve in bean oil, corn oil, etc. and impregnate by spray spraying or dipping in solution. Instead of being immersed in the solution, roll coating or Mayer bar coating may be used. Japanese Patent Laid-Open No. 52-61229 describes that an electric mosquito mat is gravure coated, but such a large-scale apparatus is not necessary. A microencapsulated drug can also be used, but in that case, it is necessary to dissolve and apply in an appropriate binder resin.
The ratio of the insecticide active ingredient to the plant fiber after drying is in the range of 0.5 to several%, as described above.

When a perforation line or a half-cut line is put on a sheet-like mosquito coil, it can be put in a spiral shape as shown in FIG. 3 or in a zigzag shape as shown in FIG. Of course, it is possible to use a circular spiral instead of a rectangular shape as shown in FIG. If the perforated line 3 shown in the figure is cut off and either one end is hung with a string or fixed to a fixed object and burned from the other end, it can be used as a mosquito coil. Moreover, if it cut | disconnects to predetermined length, it can be used only for the required combustion time. Moreover, you may carry the cut | disconnected required length and use it as a fragrance | flavor.
Most parts of the perforation line or half-cut line are cut so as not to be troublesome in cutting work, and it is necessary to devise a form that can be used if a small part is cut off. The surrounding cutting is also performed at the same time. Such processing can be performed by flat pressure punching using a punching blade.

The spiral or zigzag cut line may be a completely cut line, but in that case, the portability deteriorates. It is preferable to use a form pasted on the surface.
The sheet-like mosquito coils 1 and 2 can be subjected to silk screen printing or foil stamping. When these processes are performed, the perforation line or the half-cut line is punched after that, and finally, a light hot pressing step is performed.

It is a manufacturing-process figure of the 1st form of a sheet-like mosquito coil. It is a manufacturing-process figure of the 2nd form of a sheet-like mosquito coil. It is the state figure which put the perforation line or the half cut line spirally in the sheet-like mosquito coil. It is the state figure which put the perforation line or the half cut line in the shape of a spell in the sheet-like mosquito coil.
