[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a transpiration liquid containing bag for evaporating a medicine for the purpose of insecticide, aroma, deodorization, insect repellent, and the like, and a heat transpiration method and apparatus using the same.
[0002]
[Prior art]
Conventionally, as a heat transpiration method for pest control, a method is known in which an insecticide component impregnated in a porous substrate (solid mat) such as a fiber board is heated to evaporate. However, this transpiration method has a problem that since the insecticide component remains in the solid mat, it cannot be volatilized to the end and is wasteful. Moreover, it is desired that the transpiration amount of the insecticide component is stable over a long period of time.
[0003]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a transpiration liquid containing bag which can be used up by transpiration of the transpiration liquid to the end and which can be stably transpiration for a long period of time, and a heating transpiration method and apparatus using the same. .
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present inventors have conducted extensive research, and as a result, the transpiration liquid is contained and sealed in a bag made of a gas permeable film having at least one side flexible, and when the transpiration liquid is heated, While transpiration from the gas permeable film, the inside of the bag is depressurized as the transpiration occurs, and the two films forming the bag change in the direction of contact with each other, and the gas permeable film serving as the transpiration surface is wide with the transpiration liquid. Since the contact state is maintained in the area, stable transpiration is possible over a long period of time, and unlike the conventional mat-type heat transpiration method, a new fact that the transpiration liquid can be evaporated to the end is found, and the present invention is found. It came to be completed.
[0005]
That is, the transpiration liquid containing bag of the present invention is characterized in that at least one surface is made of a flexible gas permeable film, and the transpiration liquid is contained and sealed inside.
It is preferable that a part of the gas permeable film is transparent or translucent, so that the remaining state of the transpiration liquid in the accommodation bag can be visually confirmed.
[0006]
The heating and transpiration method of the present invention is a method in which the transpiration liquid-containing bag is heated to evaporate the transpiration liquid from at least one side of the gas permeable film, and the transpiration liquid comes into contact with the one side of the gas permeable film. It is characterized by being heated and evaporated in such a state.
[0007]
The heating and transpiration device of the present invention comprises the transpiration liquid containing bag, bag support means for holding the transpiration liquid containing bag, and a heater for heating the transpiration liquid containing bag held by the bag support means. It is characterized by that.
[0008]
In addition, an insecticide, an aromatic agent, a deodorant, a disinfectant, a fungicide, an insecticide etc. are illustrated by the transpiration | evaporation liquid in this invention. These transpiration liquids are preferably active ingredients (for example, insecticide ingredients) themselves, as in the case of an insecticide.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the case of using an insecticidal active ingredient as a transpiration liquid will be described as an example, and the transpiration liquid storage bag, heating transpiration method and apparatus of the present invention will be described.
[0010]
Fig.1 (a) is a perspective view which shows one Embodiment of the transpiration | evaporation liquid storage bag of this invention, FIG.1 (b) is the AA sectional drawing. As shown in FIGS. 1 (a) and 1 (b), the transpiration liquid containing bag 11 is formed by stacking two identical or different gas permeable films 12 and 12 and sealing the peripheral portion thereof to form a sealing portion 13. The pesticide body 14 is housed inside. Thus, since the transpiration liquid containing bag 11 was formed with the two gas permeable films 12 and 12, the transpiration liquid containing bag 11 can be used without distinguishing front and back.
[0011]
As the gas permeable film 12, any film can be used as long as it does not permeate the liquid insecticidal active substance 14 but can permeate the chemical component volatilized from the insecticidal active substance 14. Examples of such a gas permeable film include stretched or unstretched polypropylene, polyethylene (for example, linear low density polyethylene, low density polyethylene, etc.), polyethylene terephthalate, polymethylpentene, and the like. These films may be used alone or in combination of two or more. A microporous film having a large number of fine holes formed by laser light or the like in the film can also be suitably used as the film 12 alone or by being bonded to another gas permeable film. Furthermore, a porous film having a hole with a needle or the like can be used by being bonded to another gas permeable film. As a material for a microporous or porous film having holes formed by a laser or a needle, a film made of polypropylene, nylon or the like can also be used. The thickness of the gas permeable film 12 is about 10 to 100 μm, preferably 30 to 70 μm.
[0012]
Further, the gas permeable film 12 is preferably one that does not swell or tear during use, and does not cause crystallization (powdering) of the active ingredient on the surface. An example of such a film is a composite film in which two or more kinds of films are bonded together. Specifically, for example, a composite film in which stretched polypropylene, polyethylene terephthalate, perforated film (for example, perforated polyethylene terephthalate film) or the like is bonded to the outer surface of the polyethylene or unstretched polypropylene can be given.
[0013]
Further, the gas permeable film 12 is preferably transparent or translucent. This is because the remaining state of the insecticidal body 14 can be grasped visually and the end point can be easily determined.
[0014]
The pesticide base 14 to be used is a pesticide component itself that does not contain a solvent, and may be a mixture of two or more pesticide components. Moreover, you may add 1 type (s) or 2 or more types, such as a stabilizer used normally, antioxidant, an ultraviolet-ray inhibitor, and a coloring agent, to the insecticidal body 14 as an additive.
[0015]
As the insecticidal active substance 14 that can be used in the present invention, any insecticidal substance may be used as long as it evaporates by heating and exhibits a pest control effect. Examples of such an insecticidal substance 14 include transfluthrin, flamethrin, d-T80-flamethrin, empentrin, phenothrin, resmethrin, phthalthrin, d-T80-phthalthrin, S-1955 (manufactured by Sumitomo Chemical Co., Ltd.), Examples thereof include, but are not limited to, S-1264 (manufactured by Sumitomo Chemical Co., Ltd.) and isomers thereof, bifenthrin, fenfenoxuron, amidoflumet and the like. These insecticides have a vapor pressure of 4.8 × 10 ^-6 (25 ° C.) mmHg or more, preferably 4.8 × 10 ^-6 ~ 6.0 × 10 ^-3 It may be (25 ° C.) mmHg.
[0016]
The additive may be in the minimum necessary amount. Usually, the stabilizer is about 5% by weight or less, the antioxidant is about 5% by weight or less, and the ultraviolet ray inhibitor is about 5% with respect to the total amount including the insecticidal active substance 14. It may be less than wt%. In addition to these, various additives such as commonly used efficacy enhancers, volatilization rate improvers, deodorants, and fragrances can be optionally added.
[0017]
In addition, when a coloring agent such as a pigment is added to the insecticidal body 14, the visibility is further improved and the remaining state of the insecticidal body 14 can be easily grasped, so that the end point can be easily confirmed even from a distance. As the coloring agent to be added, a coloring agent that does not affect the transpiration of the insecticidal active substance 14, is not discolored by heating or light throughout the period of use, is excellent in visual recognition from a distance, and the end point is easily understood. The amount of the colorant added is 0.001 to 0.1% by weight, preferably 0.01 to 0.1% by weight, based on the total amount.
[0018]
Such a colorant can be selected from, for example, azo dyes, anthraquinone dyes, and combinations of two or more of these dyes. Specific examples include pigments such as orange No. 403, green No. 202, purple No. 201, red No. 225, and yellow No. 204.
[0019]
The amount of the insecticidal active substance 14 accommodated in the transpiration liquid containing bag 11 is particularly limited because it is appropriately determined according to the transpiration of the drug used, the transpiration amount per unit time, the target transpiration duration, and the like. Although it is not a thing, about 75-4500 mg normally, Preferably it should just be about 150-1500 mg. Further, the size of the transpiration liquid containing bag 11 may be appropriately determined according to the amount of the insecticidal active substance 14.
[0020]
Such a transpiration liquid containing bag 11 is formed into a bag shape by, for example, laminating films 12 and 12 cut into a predetermined size and sealing three sides, and then a predetermined amount of insecticidal body 14 is placed inside the bag. After the injection, the remaining side can be sealed and sealed. Examples of the sealing method include thermal bonding and bonding with an adhesive.
[0021]
The evaporating liquid storage bag 11 may be placed directly on the heater surface, and the internal insecticidal body 14 may evaporate by heating the heater. As a preferred evaporating method, a heating evaporating apparatus 21 as shown in FIG. The transpiration liquid containing bag 11 is placed in the tray 22 (bag support means), and the tray 22 is placed on the sheet heater 23. The heater 23 heats the transpiration liquid containing bag 11 through the tray 22 with the heater 23. The method of evaporating the insecticidal active ingredient 14 is mentioned. The insecticidal body 14 is evaporated from the surface of the gas permeable film 12 on the upper surface.
[0022]
The tray 22 is made of a material having high thermal conductivity such as a metal such as aluminum. Further, the tray 22 may be fixed to the heat generating surface of the heater 23. By using the tray 22, heat can be uniformly transmitted to the entire lower surface of the transpiration liquid containing bag 11, and the film 12 of the transpiration liquid containing bag 11 is brought into direct contact with the heater 23. Thermal degradation can be prevented.
[0023]
The heating temperature of the transpiration liquid containing bag 11 at this time is appropriately determined in consideration of the volatilization amount per unit time of the active ingredient, and the surface temperature of the film 12 on the heater 23 side is usually about 40 to 160 ° C., preferably It heats so that it may become the range of about 60-120 degreeC. In addition, the temperature of the insecticidal body 14 in the transpiration liquid containing bag 11 at the time of heating is about 45 to 165 ° C, preferably about 65 to 125 ° C.
One of the two films 12 and 12 of the transpiration liquid containing bag 11 may be a gas impermeable film. The gas non-permeable film includes not only substantially non-gas permeable film but also inferior gas permeable film.
[0024]
The transpiration liquid containing bag 11 may be used as it is, but may be supported by a frame (bag support means) at the time of use. FIG. 3A is a sectional view showing an example of a structure supported by a frame, and FIG. 3B is a plan view thereof. As shown in FIGS. 3A and 3B, the structure 41 has a structure in which the peripheral seal portion 13 of the vaporized liquid storage bag 11 is sandwiched from above and below by two frames 42 and 42. Examples of the method for holding the vaporized liquid storage bag 11 include a method of bonding the holding portions 43 and 43 and the seal portion 13 by heat bonding or bonding using an adhesive, a method of holding the bolts, a holding tool, or the like. For the frame body 42, for example, a metal such as aluminum, a heat resistant resin, or a heat resistant material such as wood can be used.
[0025]
In use, the structure 41 may be placed on the surface of the heater 53 and heated as shown in FIG. Thereby, the active ingredient can be evaporated from the gas permeable film 12 on the upper surface of the transpiration liquid containing bag 11. At this time, the evaporating liquid storage bag 11 is separated from the heater 53 by the frame body 42 and does not directly contact the heater 53, so that the gas permeable film 12 is deteriorated by directly contacting the heater 53. Can be prevented. Moreover, since the frame bodies 42 and 42 are arrange | positioned at both surfaces of the transpiration | evaporation liquid storage bag 11, it can be used without the front and back distinction. The heating temperature of the transpiration liquid containing bag 11 may be approximately the same as that of the heating transpiration device 21 described above. The structure 41 may be placed on the surface of the heater 53 via a tray.

Slits 73, 73 are formed, and a plurality of notches 74 are formed at the upper end and the lower end of the frame 70.
[0027]
For example, when the gas permeable film on the lower surface is a hard film, the both ends of the vaporized liquid storage bag 11 need only be inserted into the slits 73 and 73. On the other hand, when the transpiration liquid containing bag 11 is composed of two flexible soft films, a fixing means (not shown) for fixing and holding both ends inserted into the slits 73 and 73 is provided. Alternatively, a support member such as a mesh plate may be placed between the slits 73 and 73, and the transpiration solution containing bag 11 may be placed thereon.

At this time, since a plurality of notches 74 are provided at the lower end of the frame body 70, outside air flows into the frame body 70 from the notches 74, and then the gap between the transpiration liquid containing bag 11 and the frame body 70. 76 (FIG. 5C) passes as an ascending current. For this reason, the active ingredient evaporated from the transpiration liquid containing bag 11 can be rapidly diffused. The outside air intake is not limited to the notch 74, and may be a plurality of through holes or slits.
[0029]
The slits 73 and 73 are formed at substantially the center of the height of the frame body 70, and notches 74 are formed at the upper end and the lower end of the frame body 70, respectively. The surface may be placed on the heater 75.

The sealing part 13 of the transpiration liquid containing bag 11 is clamped and fixed by the clamping parts 83, 83. As a fixing method, a method similar to that of the structure 41 described above can be used. The frame 82 has an opening at the center thereof, and curved projections 84 and 84 are formed on both sides.
[0031]
As shown in FIG. 6A, the structure 81 is used by being placed on the heater 86 as it is. At this time, the protruding portion 84 serves as a spacer or a leg portion to separate the vaporized liquid storage bag 11 from the heater 86. In this state, the transpiration liquid containing bag 11 is indirectly heated by the heater 86 to evaporate the active ingredient. The structure 81 can be used without distinction between the front and back sides, and the amount of material used for the structure 81 can be reduced.

The groove portion 98 may be formed on the entire inner wall surface of each frame body 96a, 96b, or may be formed only on the inner wall surfaces at opposite ends of each frame body 96a, 96b.
[0033]
The frames 96a and 96b may be bonded to each other by bonding or the like, but can be used repeatedly by exchanging the transpiration liquid containing bag 11 as, for example, fitting by a concave portion and a convex portion provided on each opposing end face. You may do it. Further, when the gas permeable film on the lower surface is a hard film, for example, the vaporized liquid storage bag 11 may be simply inserted into the grooves 98 and 98 at both ends. On the other hand, when the transpiration liquid containing bag 11 is made of a flexible soft film, both ends inserted into the grooves 98, 98 are fixed by heat bonding, bonding with an adhesive, or the like. A support member (not shown) such as a mesh plate may be stretched between 98, and the transpiration liquid containing bag 11 may be placed thereon.
