Diffuse volatile materials. The present invention provides these gaskets that are designed to release the material when heated. K Prior Art 3 A variety of volatile materials for infusion or It is known to apply a solid porous sepal, and / or place a volatile material in a structure like a metal pan. These structures can then be placed on a heater to trigger The volatile material was evaporated to the surrounding air order. Sewing materials are reported in the US and Fujian Patent Nos. 6,031,967 and WO99 / 6679. As detailed below in this case, the disclosures of these publications and others are cited in this publication. The case is hereby incorporated into this case as McCaw's information. 15 $ and 'there may be a lag time between the beginning of heating the cymbal until the concentration of the active ingredient in the room reaches the-level. For example, when the cymbal contains an insecticide It may take several minutes to reach the desired level of anti-mosquito or other insects. These products are mainly designed to provide a prolonged release of active ingredients (for example: provide-overnight mosquito protection) Yes-a special problem. In order to reduce the lag time, you may try to increase the active ingredient concentration of the gasket. However, the active ingredient is usually expensive, and in addition, the increased concentration may cause unnecessary high pesticides or Other active ingredients are emitted into the air after the start time. 6 200415989 发明, description of the invention Another method is to change the heater so that it can operate at one temperature during the start time and other All time, it operates at a reduced temperature. Di Er, son-in-law, ^ Da Xi several people are unwilling to discard their existing heaters, and then spend money to buy new models with this function. However, in In the future, three functions of 0, .., and the package will unnecessarily increase the cost of such a heater. US Patent 5,657,574 proposes that a mosquito coil has a uniform concentration of insect pests The preparation is distributed in it, but the fragrance ring has a swollen ignition end. When the fragrance ring starts to ignite, because there are more 10 fragrance rings burning during this time, an additional amount of insecticide will be emitted. However This method is not suitable-a gasket whose bottom is designed to be directly exposed to a heat source. WO 99/66791 provides a plate-type gasket that can be inserted into a heater in an index manner. The gasket The different areas are sequentially heated. 15 The main purpose of this insert is to provide a device that can index a new shim area on the heater when the previous area is exhausted. However, the publication also describes the sequence Areas can carry different volatile components or the same volatile components at different concentrations. An example is provided of using a high-concentration area at night and a low-concentration area during the day. Unfortunately, this method requires the user to move the card in sequence while hoping to use the next stage. In WO 02/17977, the inventor company recently disclosed a pad comprising an exposed pad and a vertical groove located at the bottom of the center and extending through the pad. Different pesticides or active ingredients at different concentrations can be installed in one of the two fibrous regions. Typically, the center of the invention heats up quickly (such as the low-cost heaters used in these developing countries, which are usually warmed up near the center of the heater). Therefore, the insecticide that dwells in the center will distribute faster, while the insecticide that dwells on exposed pads will distribute more slowly. The manufacture of these gaskets is quite difficult because their materials must be completely cut, resulting in the need to assemble several segments. This increases manufacturing costs. ~ US Patent No. 4,439,415 describes a substrate that can be used to emit insecticides, which have different areas filled with different insecticides or other volatile substances. The different regions are arranged on a single-substrate 'which is made of a substance which can make the material non-absorptive, or composed of fragments of different substrates. As such, the device needs to have several components. GB 2,122,903 teaches a substrate with a paper segment or paper segments on the bottom of the box. The materials are distinguished by a separator made of rubber or synthetic resin capable of suppressing liquid penetration. Therefore, different volatile substances can be arranged on the segment without the need to move a volatile substance from the first segment to the second segment. ^ 4 The Tan method also requires difficult manufacturing steps. Therefore, there is still a need to improve volatile divergent gaskets. H Akatsuki 3 20 Summary of the Invention The present invention relates to a gasket for emitting volatile vapors. One type of the base material is a first base material portion and a second base material portion. The second base material portion is disposed at the radially outer end of the first portion. A groove is also formed on the top surface of the substrate, and a ring groove is formed on the radially outer end of the groove on the top surface of the substrate. The first substrate portion is disposed in the radial direction of the groove facing upward and the annular groove, and preferably, the groove having the opening facing upward is actually provided with a cup-shaped structure in the center. The first substrate portion has been coated with a first volatile material, and the volatile material includes a member selected from the group consisting of a pesticide, a fragrance, a deodorant, and a combination thereof. Active ingredient. The second substrate portion is disposed at the radial outer end of the annular groove, and it has been coated with a second volatile material. The volatile material is selected from the group consisting of pesticides, fragrances, The combination of deodorant and ingredients constitutes the unique Qiu ingredients. β The first volatile material may have an active ingredient that is not present in the second volatile material, or the second volatile material may have an activity that is not present in the first volatile material Ingredients. Optionally, the first volatile material may be formulated with at least one active ingredient that is the same as the active ingredient formulated in the second volatile material, and the active ingredient may be different from that formulated in the first volatile material. The concentration is higher in the second material. There is another kind of selectivity for the volatile material. The first volatile material can have at least: the same activity as the active ingredient formulated in the second volatile material, but the rest are formulated in the first type. The active ingredients in the volatile material can be formulated by the person. The active ingredients in the second volatile material are not exactly the same. Based on this, the release rate can be reduced by selecting a suitable dissolving and binding agent. The use of the term "shim" in this case includes "iron knife", "finding", "invention description" and "any gasket". The term "insect control" is defined as killing, repelling or otherwise altering the behavior or breeding of 5 insects. The term "insect control reagent t 2" used in this case order has the broadest meaning to include not only insecticides and insect repellent insects, but also growth regulators and other agents capable of achieving pest control. The definition of "insects" means real insects and 10 small animals controlled by insects, insects, insects, and other energy sentences, the same S-form, or with the same reagents as insects. Generally, the position of the groove with the opening facing upward on the base material can generally be chosen to be placed on the heater centered on the heating point of the heater. Therefore, for most cymbals, the groove with its opening facing up lies at the radial center of the cymbal. In the implementation of a pest control method, the present invention proposes to use tBJ volatile active ingredient in the central groove. It is particularly preferred that the volatile material formulated in the outer edge region of the substrate is Pynamin Forte, whose release rate is lower than that of piperonyl ether, and in the center groove The active ingredient of the volatile material is transfluthrin. In another form, the present invention provides a method for controlling insect pests. The sepals are placed on a heater Then, the cymbal is heated, thereby causing the first and second volatile materials to be emitted from the gasket. In another form, the present invention provides a method for constructing such a diffusive cymbal. A piece of insert board made of a substrate material was obtained. Its 10 200415989 玖, after the description of the invention, a central part of the insert board and ^ a each around the central part of 仫 4. 卩 points, thereby forming -A center groove with one side, with the opening facing upward 5 and then placing the first volatile material in the center groove facing upward, and placing a different volatile N 1 '< Two kinds of volatile materials in the environment The role of the edge groove at the radially outer end of the insert plate portion can minimize the leakage between the two parts of the cymbal (for example, during storage of gaskets for transportation, storage, or store display). 10 15 This method can also include the step of sticking a metal layer on the bottom surface of the board. This can cause the heater to dissipate heat more quickly (for example: the entire substrate is covered, the heat can be removed by a The hot spots of the heater are spread.) When used as an insect control device, the device of the present invention allows the user to quickly achieve the desired protection without wasting a long time of protection. The deodorant or odorant in charge At present, the present invention has the advantage of quickly covering the existing odor (for example, in a bathroom), without the need to lose the ability to provide aroma for a long time.
本發明於更進一步係能夠使一部便宜之加熱器（於加 熱面上之加熱不均一）之缺點改變成優點。這是藉由將該 中心凹槽置放於該加熱器之一個中心部分來予以達成。 這些優點可以在允以一種非常有效之製造方法下被達 成。一種低成本之壓鑄操作能夠快速形成該開口朝上之凹 槽及環溝，且其灌注可經由使用杯子來予以協助。 應可被暸解的是該杯子具有兩種主要的功能。第一種 功能是提供一種快速灌注墊片中心區域之方法（可將揮發 11 200415989 玖、發明說明 物質倒人該杯+，然後令其經由該杯子之側璧渗漏至該第 一個部分中）。這可減短引發一有效灌注所需之時間，因 此加速製造之加工過程。 第二種功能是該杯子的底部很靠近加熱器。於某些實 5施例中（例如：當材料已被移除時），這可降低該材料本身 的絶熱性，而於加熱器起動後加速活性成份開始散發。 本發明之這些及其他優點可由下列描述來顯明。下列 描述係參照該等闡釋本發明較佳實施例之檢附圖式。然而 ，本發明之申請專利範圍應視整個本發明所涵概之範疇來 10 作判斷。 圖式簡單說明 第1圖是一個已被置放於一部加熱器上之本發明發散 墊片之透視圖； 第2圖是第1圖發散墊片沿第丨圖之線2-2之剖視圖； 15 第3圖是一個墊片上形成有一個中心凹槽之基材部分 之俯視平面圖； 第4圖是第3圖基材之俯視平面圖，但其上同時形成有 一個環溝；

之raid®加熱器，亦可使用其他的加熱器，其包含但不限 制於那些具有加熱面呈水平、垂直或其他方向之加熱器。 忒墊片10基本上是一種像插板之基材，其在大約中心 5設置有一個杯形凹槽，且於該中心凹槽18之近距離内設置 一圍繞環溝20。該環溝將該基材16區分為一個第一個/内圈 基材部分22(設置於該中心凹槽18與該環溝?〇之間），以及 一個第二個/外圈基材部分24(居於該環溝2〇之徑向外端）。 現在參照第2圖，該基材16可以藉由自基材“之中心 1〇移除材料或藉由壓鑄該材料來構型。類似地，該環溝2〇可 以挖開該基材16或使用一種壓鑄裝置來壓製。最佳地，該 中心凹槽18與該環溝20是同時於一種施加於基材上之單次 壓鑄壓製中被形成。 該中心凹槽18與該環溝20較佳是不延伸至該基材16之 15底部，藉此使該基材16保持是一片單件材料。該第一個及 第二個基材部分22及24可以不同的活性成份及/或不同位 准之活性成份來處理，或以不同的非活性成份添加物物來 予以設置，俾以產生不同散發速率或不同的功效。 最佳之本發明基材16環溝是被黏貼至一金屬薄片背襯 20 26。這可改善由該加熱器14至該墊片1〇之熱傳導性。 該基材16之上半部較佳是一種以紙漿/纖維素為主之 材料（例如··一片紙板，或一種紙板棉混合物）製成。該基 材能夠被裁剪及尺寸化，俾以置放入一傳統加熱器14之加 熱面板12上。 13 玖、發明說明 、任擇地，，亥基材可以其他的多孔性材料，例如：合成 纖維、燒結玻璃、聚合塊、塑膠粒、天然或合成織物、陶 瓷材料（例如·赤土陶或陶土）及其他吸收性或吸附性多孔 材料來予以製成。當使用陶曼材料時，該中心凹槽18可以 5種適合之陶究釉料（例如：以石夕為主之不易燃透明釉料） 來予以塗覆。 第3-5圖是顯示處於各種不同構型階段之墊片。於 k疋種適合之基材16材料後，可於該基材丨6形成中心凹 槽18。同時還形成圍繞環溝2〇。 1 〇 /内圈基材部分2 2之最佳形式是呈-種救生圈之形狀 第3-5圖顯不該中心凹槽18與該環溝川可以設置成數種 不同的形狀’而使該部分22具有多種其他的形狀。最希望 的是該環溝是完全或以至少18〇。之角度來包圍該中心凹槽 μ ’俾以助於由該外環基材部分24分隔出該第—個基材部 襄溝有助於使邊活性成份或揮發性材料由該内圈 基材部分22至該外環基材部分24之滲漏減至最少。 由於亥環溝典型地是不挖通插板，因此於該部分22及 24之間罪近該金屬薄片襯底26處可能會有些許滲漏。然而 ;X展溝相g殊，滲漏基本上是可避免的，特別是當 20揮發性物質在加熱步驟中快速移動之期間。 見在參R?、第5圖，該金屬薄片襯底26可以被黏貼在該 基材16之底面。該襯底26可以一種鋁或其他金屬薄片製成 ’且其可以藉由使用一種聚合性黏劑來黏貼至該基材。一 種此種黏劑是“711”（商業上可購自New Berlin, Winsconsin 14 玖、發明說明 之ManUfacturer Resources，^ )。其他可被接受之黏劑是 由丙稀酸、胺基甲酸乙酉旨及其他具有溫度财受性之材料所 構成。可選擇性地使用其他連接_種金屬性薄片至該基材 16之方法。 5 於該金屬薄片襯底26被連接至該基材16之後，一包含一 種所欲活性成份之第-種揮發性材⑽可以被滴注或傾倒入 該中心凹槽18内。該材料28會快速滲漏入該第一個部分& 藉此來灌注該部分。該環溝2G會抑制該活性成份進—步渗漏 或漫延至剩餘之該墊片10及至該外環基材部分24。 10 一包含一種活性成份（其較佳是不同於該第一種揮發 性材料）之第二種揮發性材料30可以塗覆、灌注或予以施 加至該外環基材部分24。該環溝2〇亦可限制該第二種揮發 性物質向内滲漏至該第一個部分22。 孩外％基材部分24可以一種具有一種缓釋活性成份之 15第二種揮發性材料30來予以灌注，且該中心凹槽18可以一 種具有一種速釋活性成份之化學性質相異之第一種揮發性 材料28來予以塗覆。於最佳之昆蟲防制裝置中，該第二種 揮發性材料30是100亳克之一種具有一種由化學組成物·· 40%地亞列寧（Pynamin Forte®)(一種殺蟲劑有效成份）、4〇% 20胡椒基丁醚（PiPeronyl butoxide)(PBO，協助性/釋放試劑）及 20% Isopar Μ(碳氫化合物溶劑）所配製成之液體溶液。 一種供用於此種塾片之第一種揮發性材料2 §是5 〇毫克 之一種具有由4%拜富寧（transfluthrin)(殺蟲劑之活性成份） 及96% IS0par E(碳氫化合物溶劑）所配製成之化學組成物之 15 200415989 玖、發明說明 液體溶液。拜富寧（transfluthrin)因為其具有一較高之蒸氣 壓’所以比地亞列寧（Pynarnin Forte)揮發更快。 可選擇性地，該揮發性材料28及30可包含任何一種其 他適用之已知殺蟲劑、驅蟲劑、生長調節劑或其他昆蟲防 5 制試劑。例如，該揮發性材料22及24可包有機磷殺蟲劑、 脂質本曱驢胺基殺蟲劑、天然驅蟲劑（例如：香茅油、天 然除蟲荆及除蟲菊萃取物）以及合成之除蟲菊S旨。適合之 除蟲菊酯包含：諸如異亞列寧（D-allethrin)之亞列寧 (allethrin)、地亞列寧（Pynamin⑧）、拜富寧（benfluthrin)、 10 畢芬寧（bifenthrin)、右亞列寧（S-bioallethrin)、百亞列寧 (esbiothrin)、右亞列寧（S-bioallethrin，商品名 esbiol)、百

disadvantages of an inexpensive heater (uneven heating on the heating surface) into advantages. This is achieved by placing the central groove in a central portion of the heater. These advantages can be achieved while allowing a very efficient manufacturing method. A low-cost die casting operation can quickly form the grooves and ring grooves with the openings facing up, and the pouring can be assisted by using a cup. It should be understood that the cup has two main functions. The first function is to provide a method for quickly filling the central area of the gasket (it can pour the volatile 11 200415989 玖, the substance of the invention into the cup +, and then let it leak into the first part through the side 璧 of the cup ). This can reduce the time required to initiate an effective infusion, thereby speeding up the manufacturing process. The second function is that the bottom of the cup is very close to the heater. In some embodiments (for example, when the material has been removed), this can reduce the thermal insulation of the material itself, and accelerate the emission of active ingredients after the heater is activated. These and other advantages of the invention will be apparent from the following description. The following description refers to these drawings for explaining preferred embodiments of the present invention. However, the scope of patent application of the present invention should be judged based on the entire scope of the present invention. Brief Description of the Drawings Figure 1 is a perspective view of a divergent gasket of the present invention that has been placed on a heater; Figure 2 is a sectional view of the divergent gasket of Figure 1 along line 2-2 of Figure 丨15 FIG. 3 is a top plan view of a base material portion with a central groove formed on a gasket; FIG. 4 is a top plan view of the base material of FIG. 3, but a ring groove is formed at the same time; FIG. 5 Is an exploded perspective view of the cymbal of Figure 1; and Figures 6A-6F are top views of an alternative embodiment of the gasket of the present invention. Detailed description of the preferred embodiment t u Referring first to FIG. 1, it is shown that a gasket 10 is placed on a horizontal heating surface 12 of an electric heater 14. The heater 14 may be a 12 200415989 发明, invention description resistance heater, such as the raid® heater sold by sc Johnson & sn, Inc., or other heaters, This includes, but is not limited to, those heaters having a heating surface that is horizontal, vertical, or otherwise. The cymbal gasket 10 is basically a substrate like a board, which is provided with a cup-shaped groove at about the center 5 and a ring groove 20 is provided within a short distance from the center groove 18. The annular groove divides the substrate 16 into a first / inner ring substrate portion 22 (located between the central groove 18 and the annular groove?), And a second / outer ring substrate portion 24 (at the radially outer end of the annular groove 20). Referring now to FIG. 2, the substrate 16 may be configured by removing material from the center 10 of the substrate or by die-casting the material. Similarly, the annular groove 20 may dig the substrate 16 or A die-casting device is used for pressing. Optimally, the central groove 18 and the annular groove 20 are simultaneously formed in a single die-casting pressing applied to the substrate. The central groove 18 is compared with the annular groove 20 Preferably, it does not extend to the bottom of 15 of the substrate 16, thereby keeping the substrate 16 as a single piece of material. The first and second substrate portions 22 and 24 may have different active ingredients and / or different Level of active ingredients to treat, or set with different inactive ingredient additives, to produce different emission rates or different effects. The best 16 ring groove of the substrate of the present invention is adhered to a metal sheet Backing 20 26. This can improve the thermal conductivity from the heater 14 to the pad 10. The upper half of the substrate 16 is preferably a pulp / cellulose based material (eg a piece of cardboard , Or a cardboard-cotton blend). The substrate can be cut and sized It is placed on the heating panel 12 of a conventional heater 14. 13 Description of the invention, optionally, the substrate can be other porous materials, such as: synthetic fibers, sintered glass, polymer blocks, plastic Granules, natural or synthetic fabrics, ceramic materials (such as terracotta or terracotta), and other absorbent or absorbent porous materials. When using talman materials, the center groove 18 can be 5 kinds of suitable ceramics Glaze (for example: non-flammable transparent glaze mainly composed of Shi Xi) to be coated. Figures 3-5 show the gaskets in various different configuration stages. After 16 kinds of suitable substrates 16 materials A center groove 18 can be formed on the substrate 丨 6. At the same time, a ring groove 20 is also formed around the substrate 10. The optimal form of the substrate portion 22 of the inner ring is a shape of a life buoy. The central groove 18 and the ring groove can be provided in several different shapes, so that the portion 22 has a variety of other shapes. It is most desirable that the ring groove is completely or at least 180 ° to surround the center. Groove μ '俾 to help with the outer ring substrate Separation of the first substrate portion Xianggou at 24 points helps to minimize leakage of edge active ingredients or volatile materials from the inner ring substrate portion 22 to the outer ring substrate portion 24. The trench is typically not dug through the plug board, so there may be some leakage between the portion 22 and 24 near the metal foil substrate 26. However, the X channel is relatively different, and the leakage is basically possible. Avoided, especially when 20 volatiles move rapidly during the heating step. See reference R ?, Figure 5, the metal foil substrate 26 can be adhered to the bottom surface of the substrate 16. The substrate 26 It can be made of an aluminum or other metal sheet 'and it can be adhered to the substrate by using a polymerizable adhesive. One such adhesive is "711" (commercially available from New Berlin, Winsconsin 14 玖, ManUfacturer Resources of the Invention, ^). Other acceptable adhesives are made of acrylic acid, urethane, and other materials that are temperature-sensitive. Alternatively, other methods of attaching a metallic foil to the substrate 16 may be used. 5 After the metal foil substrate 26 is connected to the substrate 16, a first volatile material containing a desired active ingredient can be dripped or poured into the central groove 18. The material 28 quickly leaks into the first section & thereby filling the section. The ring groove 2G will inhibit the active ingredient from leaking or spreading to the remaining gasket 10 and to the outer ring base material portion 24. 10 A second volatile material 30 containing an active ingredient, which is preferably different from the first volatile material, may be coated, poured, or applied to the outer ring substrate portion 24. The annular groove 20 can also limit the second volatile substance from leaking inwardly to the first portion 22. The outer substrate portion 24 may be infused with a second-release active ingredient 15 and a second volatile material 30, and the central groove 18 may be a first-released active ingredient with different chemical properties. A volatile material 28 is applied. In the best insect control device, the second volatile material 30 is 100 g. It has a chemical composition of 40% Pynamin Forte® (an active ingredient of an insecticide), 40% 20 piperonyl butyl ether (PiPeronyl butoxide) (PBO, assisting / releasing agent) and 20% Isopar M (hydrocarbon solvent) formulated liquid solution. A first volatile material for use in this type of cymbal 2 § is 50 mg of a compound with 4% transfluthrin (the active ingredient of an insecticide) and 96% ISOpar E (a hydrocarbon solvent ) 15 200415989 of chemical composition formulated 玖, invention description liquid solution. Transfluthrin volatilizes faster than Pynarnin Forte because it has a higher vapor pressure '. Alternatively, the volatile materials 28 and 30 may include any other known insecticide, insect repellent, growth regulator or other insect control agent. For example, the volatile materials 22 and 24 may include organophosphate insecticides, lipid-based ammonium amine-based insecticides, natural insect repellents (eg, citronella oil, natural pyrethrum and pyrethrum extract) Synthetic pyrethrum S purpose. Suitable pyrethroids include: allethrin such as D-allethrin, Pynamin (R), benfluthrin, 10 bifenthrin, dextrolenin (S- bioallethrin), esbiothrin, S-bioallethrin (trade name esbiol), bioresmethrin, cycloprothrin, cyf! uthrin, type B- Beta-cyfluthrin, cyhalothrin, deltamethrin, empenthrin 15, esfenvalerat, fenpropathrin, fenvalerate , Flucythrinate, tau-fluvalinate, kadethrin, permethrin, phenothrin, such as Etoc® prallethrin), 歹 | J's resmethrin, tefluthrin, tetramethrin or tralomethrin. Other volatile pesticides described in U.S. Patent No. 4,439,415 can also be used. Volatile insect growth regulators such as metoprene and hydroprone can also be used. Alternatively, or in addition, fragrances such as lemon essential oil, eucalyptus essential oil, and citronella, as well as deodorants according to the invention, may be used. Although the ring groove 20 shown can effectively restrict the active ingredient from spreading or leaking from the one substrate portion 22 to the second substrate portion 24 (and vice versa), the ring groove 20 can also be a A sealant (for example, a rubber material or another form of material) is used to avoid absorption of the active ingredient 28, and to help any kind of active ingredient spread. In one embodiment, when the gasket 10 is heated for the first time, the gasket 10 can generate a very large amount of emitted volatile material 28. Therefore, the subsequent remaining emission rate levels are mainly generated by the second portion 24. This 10 helps to quickly protect or change a surrounding environment that was previously directed to adequate processing 'and provides long-term protection thereafter. In an embodiment (which is somewhat similar to the form of FIG. 4 but has a wider bad groove), the center groove 18 may be disposed in the center of the substrate 16 and has a diameter of about 0.34 cm. diameter. The ring groove 20 may have a ring shape having an inner diameter of about 1.06 cm and an outer diameter of about .75 cm. The thickness of the substrate 16 is approximately 0.26 cm, and the depth of the central groove 18 and the mounting groove 20 may be approximately 0.1 cm or more individually. Figures 6A-F show various changes in the configuration of the central groove 18 and the annular groove 20. In particular, the ring groove 20 is shown as a polygonal shape 20 (6A), an oval shape (6B), as a star (6C), as a wide circle (6D), as a star shape ( 6E), and like a type of four arrows (6F). The color of each different shim area can be individually and differentially dyed, for example, by the inclusion of various dyes in the infusion material. Since dyes are also volatile, discoloration or discoloration can be used to judge old and new. 17 200415989 发明, description of the invention The shape of the central groove 18 can also be changed, as shown in the figure for example, in which an oval central groove 18 is shown. Although it is shown as a single ring groove 20, it can be clearly understood that a cymbal plate with several concentric ring grooves of different types and different types of volatile substances can also be set to generate 3 or more different divergent areas. There are other changes in the preferred embodiment that are also intended to be included in the scope of the patent application. 15 In addition, the gasket of the present invention can also be-with an anti-infective device / Aromatizer / Deodorizer 'uses a variety of different active ingredients for their purpose, including, but not limited to, ethylene glycol, ethylene glycol, and dipropylene glycol known in the art. Furthermore, Even if it has the same active ingredient and substrate, a cymbal tablet with reference to the present invention can be used under the condition that the solvent, adhesive and the like are adjusted to appropriately regulate the release rate. For example, the central volatile substance may include a formulation PynaminForte® 'in a hydrocarbon solvent, and its volatile substances can be the same or have some piperonyl but () xide. Therefore, the scope of patent application of the present invention should According to these, the scope of the present invention is determined. [Industrial application] 20 The present invention is to provide improved volatile materials for pest control, fragrances, anti-infectives and similar practical volatile materials, especially those in the first When it is used, it will produce a more intense divergent gasket.
