Description

Aerosol jetting device

The present invention relates to aerosol injection device for pest control that can be mass sprayed.

The aerosol spraying device can simply control the pest by repeatedly spraying the aerosol enclosed in the container against the pest.

It is preferable that the aerosol injection device can be easily used by anyone, and the aerosol enclosed in the container can effectively control pests, and a safe composition is preferable.

As a structure of the aerosol injection apparatus, the overall external view of the aerosol injection apparatus 10 is shown in FIG. In Fig. 1, reference numeral 1 denotes an aerosol container, 2 denotes a cap portion of a triggered aerosol cap, 31 denotes an operation unit body, 34 denotes a trigger portion, and 37 denote a jet port. Reference numeral 7 denotes a virgin seal which is installed so that the operation part is not operated accidentally during storage or transportation.

FIG. 6 shows the cap 2 taken out, FIG. 7 is a bottom view of the cap 2 viewed from below, and (3) the valve stem 6 protruding from the top of the container 1. It is an operation part which inserts and operates a valve stem. Reference numeral 31 denotes an operation unit body, 32 a fixing plate, 33 a fixing lever, and 34 a trigger portion, respectively. Reference numeral 35 denotes a step inserting portion, 36 denotes a liquid passage in the operating portion 3, 37 denotes a spraying head of the liquid passage tip, and 38 denotes a discharge portion. Spray orifices are shown respectively.

(4) is a cover part fixed to the mount (5) of the container (1), (41) is a supporting rib of the attachment lever 33, (42) is a supporting cut- off) and 43 are the cover circumferential walls, and 44 are the openings at the bottom of the circumferential wall.

In the conventional aerosol cap, since the gap portion 44 was narrow, even if the cap portion 2 was to be disassembled, a tool could not be inserted and it was difficult to remove the cap portion 2.

As described above, the virgin seal is provided on the cap so that the operation unit does not operate accidentally during storage or transportation of the aerosol injection device. That is, the virgin seal is used to ensure that no operator is sprayed at all until the operator starts using the aerosol spray device.

However, when the virgin seal is used as another type of triggered aerosol cap as shown in Figs. 9 and 10, the possibility of the following problems may be considered.

9 and 10 show the virgin seal 102 provided on the upper portion 101 of the operation unit body 107 having the trigger portion 100 and the ejection portion to be fixed to the side wall edge portion 104 of the standing portion 103. One aerosol cap 105 is shown. In the standing part 103, when the force enters too much when holding the virgin seal 102, the operation part main body 107 may be lifted upwards, and the stem insertion part 109 may be pulled out from the valve stem 110. FIG. That is, since the bending gap S1 is formed between the rear wall 106 of the standing part 103 and the bend part 108 of the operation part main body 107, for example, a thumb is attached to the front-end | tip of the operation part main body 107. On the contrary, when holding the virgin seal 102 by applying the forefinger to the virgin seal 102, the bent portion 108 can be greatly bent by lifting the operation unit main body 107 backward. For this reason, as shown in FIG. 11, the step insertion part 109 may ride up on the valve stem 110 in some cases. In this case, there is a possibility that the valve stem 110 is pressed and the contents are injected. In addition, as described above, in addition to the normal injection valve for pressing and injecting the valve stem 110, a stem fixing part which is also removed from the valve stem for a so-called inclined valve for tilting and injecting the valve stem horizontally. There is a possibility that the valve stem may be tilted to misinject the contents.

On the other hand, as an aerosol in a container, various examinations are made about the means for enhancing the effect, For example, the stock solution containing the pest control component with a strong insecticidal effect as an active ingredient, or containing a pest control component (stock solution) ), The composition or the amount of injection is adjusted.

For example, as an aerosol (contents) in an aerosol container in an aerosol spraying device, a preparation of a mass spray type in which a control effect is sufficiently obtained by treating the pest control component in a larger amount is more efficient, and the embodiment thereof Has been reviewed in various ways.

In Japanese Patent Application Laid-Open No. 46-20837, insecticidal components are dissolved in a solution having a boiling point of 100 ° C. or lower and a total point of 0 ° C. or lower. pressure 3~7kg / cm ² / by at 20 ℃ put a special valve for injecting at least 15ml to one second short ejection insecticidal extensively ejection insecticidal ingredient to (300ml in 20 seconds) I is disclosed. However, in this technique, since a special valve is used, the manufacturing cost is high or the entire contents are ejected all at once, so that it cannot be used repeatedly, and thus there is a deficiency in versatility.

Also disclosed is aerosol composition for mass injection comprising a kerosene-based stock solution and a propellant comprising a fluorofluorohydrocarbon, a flammable liquefied gas, a carbon dioxide gas, and the like. However, this technique is primarily aimed at reducing fluorinated chlorinated hydrocarbons (freons) used in propellants.

In the various conventional techniques as described above, in order to increase the pest control effect, excessively spraying the contents, such as clogging occurs on the treated surface, as a result, safety such as wet floor or walls, or increased flame length It was flawed in terms of things. Therefore, when the spraying amount is reduced to suppress the wetting of the treated surface and the increase in the flame length, the pest control effect becomes insufficient.

In addition, the effects of aerosols on the target pests are not always satisfied by the user, but are changing due to the occurrence of resistance to pest control components of the pests, changes in the living environment, and furthermore, legal regulations. Therefore, the development of the aerosol superior to the conventional one is continuously desired.

Therefore, the aerosol injection apparatus (particularly the one capable of mass injection) has various problems in the conventional apparatus, and there is room for improvement.

First, the excellent pest control effect in the aerosol injection apparatus of this invention is demonstrated.

In the present invention, the pest control effect refers to all effects of controlling pests such as insecticidal effect, ability to knock down pests quickly, and ability to drive off pests.

According to the present invention, after the injection of the aerosol injection device for controlling pests, by using an aerosol injection device that gives an injection in which the air concentration of the pest control component in the injection space is not reduced for at least 5 minutes, The air concentration of the control component is maintained for a long time at a level higher than the air concentration by the conventional aerosol, thereby obtaining an excellent pest control effect. On the other hand, in the conventional mass injection type aerosol injector, the concentration in the air is high immediately after the injection, but the air concentration of the component in the injection space decreases shortly after the injection, and the effect of the pest control component acting on the pest is small. It becomes insufficient.

This is explained more easily by way of example.

After being injected in the aerosol injector, the air concentration of the pest control component in the sprayed air is determined by the amount of the pest control component released in the aerosol injector. However, if the liquid droplets formed after the injection from the aerosol injection device are very minute, the liquid droplets will be scattered immediately after the injection and do not reach the target sea layer or the pest control component rapidly evaporates from the aerosol injection, Immediately after the injection, the concentration in the air reaches its maximum, and the concentration in the air gradually decreases thereafter by the scattering. On the contrary, the larger the size of the liquid drop, the more the sprayed liquid drop is dropped from the spray space before the component is sufficiently discharged from the liquid droplet, and the concentration in the air in the spray space decreases without increasing so much. Therefore, if the size of the liquid drop is in a certain range, the time for the liquid drop to exist in the spraying space is sufficiently long, the component from the liquid drop is sufficiently released, and the concentration in air in the spraying space increases, After time, it turns back to a drop. In this way, when the air concentration increases for a long time, the air concentration of the control component in the spray space is kept at an effective concentration for a long time, and can effectively act on pests. An object of the present invention is to form a state of such an injection product.

However, the concentration in the air is also influenced by the rate of diffusion of the control component from the liquid droplets, the volatilization rate, and the like, and also by the diffusion rate from the injection space, and the like, and is not determined solely by the size of the liquid droplets as described above.

In the present invention, in the spray defined as sprayed by the aerosol spraying device, the concentration in the air of the pest control component is not reduced for 5 minutes after the spraying in the aerosol spraying device. To achieve the object of the invention.

In addition, in the conventional mass injection type aerosol spraying device, the sprayed treatment surface tends to get wet or the flame length increases. In the present invention, however, the use of an aerosol injector which imparts an injection in which the concentration in the air after the injection does not decrease for 5 minutes can be excellently suppressed to increase the wettability of the treated surface and increase in flame length.

After the injection of the aerosol injector for pest control, an aerosol injector in which the concentration in the air of the pest control component in the injection space does not decrease for at least 5 minutes, preferably 7 minutes is preferable.

In the present invention, the concentration in the air of the pest control component in the spray space does not decrease for at least 5 minutes when the air concentration is increased immediately after the spraying, and the maximum concentration is substantially maintained after reaching the maximum. And, when the concentration in air increases immediately after spraying for at least 5 minutes. Preferably, the concentration in the air is increased for 5 minutes.

In the present invention, the injection space refers to a space surrounded by a trajectory drawn by particles containing the pest control component injected from the aerosol injection device.

In the present invention, the term "after injection" refers to a period after the injection of the aerosol injection device is completed. Injectables are those injected from an aerosol injector.

As a means for preventing the concentration in the air after injection of the pest control component of the aerosol spraying device of the present invention not to be reduced until at least 5 minutes, it is not limited as long as it can be achieved, but preferably the injection amount of the aerosol is 5 g or more per 5 seconds. At the same time, the volume ratio of the propellant / stock solution in the aerosol is set to 2 or more. Thereby, the said air concentration can be set, the increase in the wetness of a treated surface and the flame length is suppressed, and the pest control effect becomes excellent.

In the present invention, by specifying the amount and amount of injection of the propellant relative to the stock solution, the particles containing the injected pest control component have an appropriate particle diameter and reach farther, and also the scattering volume of the propellant. It is also very large compared to the conventional product (for example, about 6 times that of the conventional product at 2.4 seconds after injection), thereby not only maintaining the effective concentration in the air for a long time, but also excellent in pest control effect, It also works against distant pests and can effectively control them.

In the present invention, the volume ratio of the propellant / stock solution of the aerosol injector is preferably 2 to 7. In the present invention, the injection amount of the aerosol injection device is preferably 5 to 15 g / 5 seconds. Thereby, the effect of this invention becomes more remarkable.

Moreover, another preferable aspect in the aerosol injection apparatus of this invention is

5) The propellant is blended 3 to 5 times in volume ratio with respect to the stock solution containing a pest control component and a solvent, and the injection quantity of a solvent is 4.0 ml / 10 second or more.

In this case, it is more preferable that the aerosol injection device is a mass injection type.

In 5), the aerosol is sprayed on the pest by setting the ratio (v / v) of the propellant to the stock solution in a specific range and setting the injection amount of the solvent contained in the stock solution to 4.0 ml / 10 seconds. It has the effect of remarkably suppressing the movement of a pest from a place, and can exhibit the excellent insecticidal effect. Specifically, spraying an aerosol spraying device toward a pest reduces the roaming behavior of cockroaches and the like, and in particular, can stop the activity of the pest with high agility so that it rarely moves there, and also effectively prevents the pest. It can be insecticide.

In the conventional aerosol injection device, even when the injection treatment is carried out, pests may move around in the place, so that the injection of the aerosol is continued until the activity is stopped. However, in the form of 5), since the movement of the pest from the place where the aerosol is sprayed with respect to the pest can be suppressed, the number of spraying can be reduced, the consumption of the aerosol can be reduced, and it can not be wasted. . In addition, since the pests can be knocked down effectively, the amount of aerosol sprayed to the surrounding environment becomes appropriate, and the usefulness that the pollution of the human living environment can be suppressed is obtained.

Here, the suppression effect of the pest moving distance after the aerosol injection is different from the simple insecticidal effect (that is, even if the insecticidal effect is excellent, the effect of suppressing the pest moving distance after the aerosol injection is not good).

In the aspect 5 of the present invention, the injection amount of the solvent is preferably 5.0 ml / 10 seconds or more, and more preferably 6.0 ml / 10 seconds or more. Although it does not restrict | limit especially, Preferably it is about 10.0 ml / 10 second.

Moreover, in the form of said 5) of this invention, it is preferable that it is a mass injection type. Thereby, the effect of the form of said 5) is exhibited more effectively. Here, the mass injection type means that the injection amount per unit time is increased by about 3 to 7 times as compared with the conventional aerosol injection amount, and specifically, the total injection amount is preferably 20 to 100 ml / 10 seconds, more preferably. Means 25-70 ml / 10 second.

In the present invention, the injection amount of the entire aerosol and the injection amount of the solvent means the amount injected per 5 seconds or 10 seconds, and the aerosol is injected for 5 seconds or 10 seconds, and the amount or solvent of the spray injected in the meantime is measured It is obtained by doing. Since the injection amount of the aerosol injection device may not be indicated even when the amount of injection per hour shorter than 5 seconds is measured, the amount injected per 5 seconds or 10 seconds is defined as the standard amount of the injection amount.

As a means for enabling such a large volume injection, there are means such as selecting a valve hole diameter or a button hole diameter for which the target injection is possible, or adjusting the injection pressure. It is necessary to select the means by which the function becomes possible.

In the form of said 5) of this invention, the specific ratio (v / v) of an undiluted | stock solution and a propellant, the injection quantity of a solvent, a large quantity injection type, and the relationship with the said effect are explained further, as follows.

(A) A mass spray aerosol injector consisting of 50 ml of a stock solution (containing a total of 50 ml in a solvent) and 250 ml of a propellant containing 0.5 grams of pest control components (proportion of stock solution and propellant, 1: 5.00).

(B) A mass spray aerosol injector consisting of 70 ml of a stock solution (70 ml total in solvent) and 230 ml of propellant containing 0.5 gram of pest control component (proportion of stock solution and propellant, 1: 3.33).

The aerosol spraying apparatuses of (A) and (B) have the same spraying amount (for example, a large amount of spraying type three times larger than that of any conventional one) when comparing the above effects, and the amount of the pest control component in the aerosol. Even in this case, the (B) side is superior to the (A). That is, by increasing the amount of the solvent in the stock solution and increasing the ratio to the propellant, the injection amount of the solvent becomes larger, and the effect can be further increased.

In addition, in the aerosol injection apparatus of (A), when the mass injection type aerosol injection apparatus which increases the injection amount (for example, about 5 times) is set to (C), the injection amount of (C) is more than that of (A). It becomes many, and the said effect becomes more excellent. In the above aspect 5 of the present invention, the larger the injection amount is, the better.

In the form of 5) of the present invention, the amount of the pest control component which is the active ingredient does not increase, and the air of the pest control component which is the active ingredient in the atmosphere after the injection is compared with the aerosol spray device which does not enter the form of 5). Although the medium concentration is almost the same, the movement distance of the pest after spraying can be remarkably suppressed as described above, and the insecticidal effect is also excellent.

This is explained concretely.

The aerosol injection device (Sample 2 of Example 5 to be described later) and the aerosol injection device (Sample 3 of Example 5) which do not fit into the form of 5) of the present invention are injected, and the injection space The concentration of the pest control component (imiprothrin) in the body was determined.

(How to measure)

A sampling tube containing about 3 g of silica gel is installed inside the sealed chamber. Each aerosol was sprayed for a predetermined time toward the bottom and wall edges in the chamber. In addition, the injection time was set so that the quantity to which the pest control component is injected may be the same in both samples.

At 15 liters / minute in the sampling tube, the air in the chamber is sucked for 3 minutes and the spray particles in the air in the chamber are uniformly trapped in the sampling tube containing silica gel. Sampling was performed up to 20 minutes at predetermined intervals rather than immediately after injection, and the pest control components trapped in silica gel were analyzed using gas chromatography, and the concentration of the pest control components per 1 m ³ was determined by the following equation.

Airborne concentration of pest control component (㎍ / m ³ ) = pest control component analysis value (μg) / [sampling flow rate (liters / minute) × suction time (minutes) × 1000]

In the aerosol spraying apparatus of the form 5) of the present invention and the aerosol spraying apparatus not included in the form of 5), the concentrations in the air of the pest control component as the active ingredient were almost the same.

Thus, although the concentration in the air of the pest control component which is the active ingredient in the atmosphere after the spraying in this manner is almost the same, the sample of the form of 5) of the present invention has a moving distance of the pest after spraying as described below. Can be significantly suppressed, and its insecticidal effect is also excellent. Therefore, the effect of the form of said 5) of this invention is effective not only the pest control component of an active ingredient but also a pest control component, a solvent, a propellant, the ratio and injection amount of these lands, and the injection quantity of a solvent, and interacting suitably, It is expressed.

The aerosol injection apparatus of this invention is an aerosol injection apparatus which can spray pests by spraying suitably repeatedly, without spraying the whole quantity at once.

In addition, the aerosol injection apparatus in the present invention can also be combined with the aerosol container containing the propellant, the stock solution, and various aerosol caps, which is a feature of the invention, and the combination of the trigger type aerosol cap of the present invention. It is not limited.

Next, the structure of the aerosol injection device which concerns on this invention is demonstrated.

FIG. 2 is a top view of the cap 2 of the aerosol jetting apparatus 10 shown in FIG. 1, FIG. 3 is a bottom view of the cap 2 of the aerosol jetting apparatus 10 shown in FIG. 1, respectively. 4 is a side sectional view of the cap part 2 of the aerosol injection apparatus 10 shown in FIG. 1, and FIG. 5 is a side sectional view of the state which can be used by peeling off the virgin seal 7. As shown in FIG.

In FIG. 4 which is a side cross-sectional view, the operation part 3 is hold | maintained by the virgin seal 7, and the valve stem 6 is prevented by the operation part 3, even if the trigger part 34 is accidentally applied during storage or transport. It descends and it is no longer sprayed. As shown in FIG. 5, when the virgin seal 7 is removed, the valve stem inserting portion 35 and the valve stem 6 are engaged, and the operation portion 3 is a holding cutout portion 42 of the rib 41. The valve stem 6 is rotated counterclockwise by pressing a finger on the trigger portion 34 and pulling like a trigger, with the attachment lever 33 engaged in the center as the center.

As can be seen in FIG. 3, in the present invention, the width of the gap is increased so that the dismantling tool can insert the gap 45 at the lower end of the cover circumferential wall 43, so that the tool is inserted thereinto the cap part. (2) can be easily removed.

Figure 8 shows another embodiment of the aerosol injection device of the present invention.

The aerosol cap 111 of this embodiment includes a stem inserting portion 139, a ejecting portion 138, a passage portion 137 and a trigger portion 134 through which the stem inserting portion 139 and the ejecting portion 138 pass through each other. The operation part main body 131 and the standing part 119 which have is included. In addition, the base 118 of the aerosol cap 111 is fitted with the mount 5 provided in the upper part of the container 1. The standing part 119 is formed so that it may come up from this base 118, and may surround the operation part main body 131 on both sides. At the rear of the operation unit main body 131, a bent portion 133 connecting the rear wall 121 of the entrance portion 119 and the operation unit main body 131 is provided.

It is injected from the blowing unit 138 through. On the other hand, the virgin seal 117 is formed to be fixed to the side wall edge 120 of the standing portion 119, through the cutting member 116 (tear chip) in the upper portion of the operation unit body 131. When using an aerosol injection device, this virgin seal 117 is removed and used. In addition, it is difficult to cut by making the tearing part of the cutting member 116 thinner and / or thinner so that the virgin seal 117 can be easily peeled off so that the stem insert 139 does not rise to the step, and the wrong injection is performed. You can prevent it.

The feature of the present embodiment lies in that the restricting means 140 for maintaining the fitting state between the valve stem 6 and the stem inserting portion 139 is fitted into the gap portion of the bent portion 133. In this embodiment, a wedge-shaped protrusion member is used as a regulating means. When the operator removes the virgin seal 117 with a finger by this regulating means 140, even if the operator accidentally lifts the operation unit main body 131 upward, the regulating means 140 is fitted into the gap between the bent portions 133. ) Regulates the movement of the operation unit main body 131, the inclination of the stem inserting portion 139 becomes small, and the stem inserting portion 139 does not get on the valve stem 6. In addition, in this embodiment, although the wedge-type protrusion member was used as the restricting means 140, the present invention is not limited thereto. For example, the filling member may be inserted and fixed to fill the gap between the protrusion and the bent portion 133 integrally formed with the rear wall 121 in the gap between the bent portion 133. In addition, a stopping mechanism may be provided between the protruding member or the filling member and the rear wall 121 so that the protruding member or the filling member does not fall out from the gap between the bent portions 133.

Example 1

The active ingredient at the time of spraying the aerosol spraying apparatus which enclosed the aerosol of the prescription number 3 shown in the said Table 1 in the container 1 of the apparatus of FIG. 1, and the aerosol spraying apparatus of the conventional product a shown in following Table 4 ( The following test was done to measure the air concentration of phthalinsine). In addition, the conventional product a is a pest control aerosol consisting of 180 ml of a propellant consisting of a stock solution, LPG and DME adjusted to 120 ml pest control components (450 mg phthaline and 60 mg resmethrin) No. 1 kerosene It is injection volume 2.3g / 5 second. The injection amount of the aerosol injection device (invention product) of this invention is about 6 g / 5 second.

In the 1.8 m ³ chamber, a sampling tube (Φ 15 mm x 100 mm, silica gel about 6.0 g) was attached at a position approximately 1 m high at the bottom surface, corresponding to the center of the chamber. Each aerosol is sprayed for 5 seconds in the injection window (approximately 1.6 m in height), and every 3 minutes in the air sampling tube at regular intervals immediately after the injection, the air is sampled at a rate of about 18 liters / minute, and the particles in the air are Trapped. The sampling tube was installed in the injection space referred to in the present invention.

Sampling was carried out for 1 hour immediately after injection, and the active ingredient trapped in the sampling tube was analyzed by gas chromatography. Phthalin's concentration in air (μg / m ³ ) is expressed as: air concentration (μg / m ³ ) = 1000 x analysis value (μg) / [sampling flow rate (liters / minute) × 3 (minutes)] / m ³ ).

The result is shown in FIG. As shown in Fig. 12, the concentration of phthalinsine in the air of the present invention was shorter after the injection than that of the conventional product a, but rose to 7 minutes after the injection, and then became higher than the conventional product. This indicates that the spray space is maintained for a long time in a state where the concentration in the air is high, which significantly improves the insecticidal effect.

In addition, in the present invention, the proportion of the propellant is increased, so that the injected active ingredient has a suitable particle diameter, which is considered to have a significant influence on the air concentration or the insecticidal effect of this component.

On the other hand, when the characteristic of the particle | grains sprayed using the said this invention product (prescription number 3) was measured, the particle | grains of the particle diameter of 11 micrometers or less were contained in 32.3 +/- 5.8 (%) of the sprayed particles.

Moreover, the flying volume of the sprayed material after the injection of each aerosol was measured using the said this invention product (prescription number 3) and the said conventional product a. The measuring method injects each aerosol, measures the volume occupied by the sprayed liquid droplet (the volume of the space enclosed by the orbit where the droplet is drawn), and shows the result in FIG. 13.

As shown in Fig. 13, the present invention had a significantly larger scattering volume over time than the conventional product a, and was about 6 times as large as the conventional product a after at least 2.4 seconds. . From this result, it turns out that the effective air density | concentration of the pest control component exists in a wide range, and shows that the insecticidal effect is remarkably improved.

Example 2

The following efficacy test was done about the aerosol injection apparatus for pest control of this invention.

In addition, the injection amount of this invention was about 6 g / 5 second, and the aerosol injection apparatus of the conventional product a was used as a comparative example.

(Method and result)

Lower the stainless steel gauge (250 mm x 250 mm x 250 mm) containing 20 housefly (male / female = 1: 1) from the ceiling, the aerosol at a position of 1 m, 1.5 m and 2.0 m at a horizontal distance from the center of the gauge. The injection device was injected for about 1 second, and the test which observed the knockdown number of housefly and the mortality rate (%) after 24 hours was performed and averaged about 2 times. The results are shown in Table 2 below.

As is apparent from Table 2, the present invention shows excellent effects in rapidness in effect and lethal effect as compared to the conventional product a. Moreover, the pest control effect of this invention is maintained even if it becomes a long distance. This is considered to be because the particle characteristics of the sprayed particles of the present invention are appropriate and the spray reaches farther.

Example 3

The conventional product a, the comparative product which increased only the injection quantity of the conventional product a (6.0 g / 5 second), and the aerosol shown in Table 3 (the prescription numbers 1 to 4 shown in Table 1) of the container of the apparatus of FIG. In order to compare the degree of wetness to the treatment surface using the aerosol injection device (the present invention) enclosed in (1), each aerosol injection device is sprayed for 2 seconds from a distance of 20 cm toward the surface by installing a blank paper. The degree of wetting of the blank paper at that time was compared with the area (length cm x width cm). In addition, the flame length was measured. The results are shown in Table 3.

In addition, in order to compare the control effect on the housefly by using each aerosol injection device described in Table 3 above, the stainless steel gauge (250 mm x 250 mm x 250 mm) containing the housefly is lowered from the ceiling, and is horizontal from the center of the gauge. Each aerosol injection device was injected for 1.5 seconds at a position of 75 cm in distance, and each test was performed to observe the knockdown number of the housefly and the mortality rate (%) after 24 hours each time. The results are shown in Table 3.

As shown in Table 3, when the present invention was observed, the wetness of the wall surface was about the same as that of the conventional product a with a small injection amount, and the increase in the flame length was also suppressed. Moreover, in this invention, the return length from the flame source of flame length is also suppressed.

From the results of Table 3, in the present invention, when the injection amount per unit time was made constant, the tendency to decrease slightly appeared as the amount of the undiluted solution with respect to the insecticidal effect, but the insecticidal effect was completely good.

As mentioned above, although the conventional product a is a level which can be comparatively satisfied with respect to wettability and a flame length, the insecticidal effect is remarkably worse and the comparative product is a level which is comparatively satisfactory with respect to a pesticidal effect, but remarkably worsens with respect to wettability. do. Therefore, it turns out that the conventional product a and the comparative product cannot improve both wettability, flame length, and insecticidal effect.

On the other hand, the present invention obtained excellent effects in any of the wettability of the wall surface, the flame length and the insecticidal effect. In particular, if the propellant / stock solution ratio is 200/100 (2 times) to 260/40 (6.5 times), it may be better in terms of insecticidal effect.

Example 4

Next, in the aerosol injection apparatus of this invention, the insecticidal control effect in actual use condition was tested.

Male and female (1: 1) house flies (Denken strain) were loosened in a 1.8 m ³ chamber, and left for a while, and then each aerosol injection device (device) 1) was sprayed for 1.7 seconds toward the fly scattered in the chamber. The number of knocked down flies and% mortality after 24 hours were measured at each elapsed time from the start of the injection. The results are shown in Table 4 below.

As shown in Table 4, the present invention exhibited excellent effects in fastness and lethality, and also exhibited excellent pest control effect in actual use conditions, compared with the conventional products a to c. This shows that the action and effect of the aerosol injection apparatus of this invention are fully exhibited even in actual use conditions.
