In order to solve the above-mentioned problems, the characteristics of the configuration of the quantitative spray aerosol for space processing of the present invention are: A quantitative spray aerosol for space treatment, comprising: a pressure-resistant container provided with a quantitative spray valve formed by enclosing an aerosol collagen solution containing a control ingredient and a propellant; an actuator and a dip tube for supplying the aerosol collagen solution and the propellant to the quantitative ejection valve, The front end of the liquid immersion pipe is located at a height of less than 6mm from the lowest part of the pressure-resistant container, When the pressure-resistant container is placed on a horizontal plane, the spray shaft of the spray port is at an elevation angle of 10° to 60° with respect to the horizontal plane.

The inventors have conducted various examinations on the spraying direction of the quantitative spray aerosol for space treatment, and obtained the insight that in the case of spraying the medicine at an angle of about 30 to 60° obliquely upward with respect to the horizontal plane, the dispersion of the medicine to the treatment space is uniform, and the Process efficiently. According to the quantitative spray aerosol for space treatment of the present structure, the pressure-resistant container is placed on the bottom of the pressure-resistant container by placing the front end of the liquid immersion tube of the quantitative spray aerosol for space treatment at a height of 6 mm or less from the lowest part of the pressure-resistant container. In the horizontal plane, the spray axis of the spray port is at an elevation angle of 10~60° with respect to the horizontal plane. When the pest control ingredients suitable for pest control are sprayed in such a way that the spray axis of the spray port is at 30~60° with respect to the horizontal plane, the spray can be suppressed.

The quantitative spray aerosol for space treatment according to the present composition can simultaneously control flying pests, creeping pests or house dust mites.

In the quantitative spray aerosol for space treatment of the present invention, Preferably, the spray axis of the spray port is at an elevation angle of 15-50° with respect to the horizontal plane.

According to the quantitative spray aerosol for space treatment of the present composition, by making the spray axis of the spray port of the quantitative spray aerosol for space treatment form an elevation angle of 15 to 50° with respect to the horizontal plane, the spray axis at the spray port is relative to the horizontal plane. When spraying at 30-60°, since the angle of inclination of the pressure-resistant container can be grasped, the occurrence of poor spraying can be suppressed and a stable spraying state can be maintained.

In the quantitative spray aerosol for space treatment of the present invention, The front end of the liquid immersion pipe is preferably located at a height of 3 mm or less from the lowermost part of the pressure-resistant container.

According to the quantitative spray aerosol for space treatment of this structure, by placing the front end of the immersion tube at a height of 3 mm or less from the lowest part of the pressure-resistant container, even when the pressure-resistant container is sprayed at a slight inclination with respect to the horizontal plane, the quantitative spray can be The injection valve reliably supplies aerosol collagen liquid and propellant, which can suppress the occurrence of poor ejection.

In the quantitative spray aerosol for space treatment of the present invention, Preferably, the spraying force at a spraying distance of 5 cm is set to 5-50 gf.

According to the quantitative spray aerosol for space treatment of this structure, by setting the spray force at a spray distance of 5cm to 5~50gf, the sprayed aerosol collagen liquid settles uniformly and adheres to the exposed surface in the treatment space (for example, exists in the treatment space. The floor surface or the wall surface of the space, the surface of the structure of the furniture, etc.), especially the whole floor surface, can exert a practical and sufficient control effect on flying pests, creeping pests and house dust mites.

Hereinafter, the quantitative spray aerosol for space treatment of the present invention will be described. However, the present invention is not intended to be limited to the configurations and examples described in the embodiments described below.

FIG. 1 is a cross-sectional view of a quantitative spray aerosol 100 for space treatment according to the present invention. The quantitative spray aerosol 100 for space treatment includes: a pressure-resistant container 10 provided with a quantitative spray valve 12 in which aerosol collagen solution containing a control component and a propellant is enclosed, and a spray port 21 connected to the quantitative spray valve 12. The actuator 20 and the liquid immersion pipe 30 for supplying the aerosol collagen solution and the propellant to the quantitative spray valve 12 are determined according to the space treatment, and can be used to control flying pests such as mosquitoes, flies, creeping pests such as cockroaches, or house dust mites. and other pests.

[Pressure-resistant container] The pressure-resistant container 10 includes a storage part 11 for storing the aerosol collagen solution and the propellant, and a quantitative injection valve 12 attached to the mouth of the storage part 11 . The storage portion 11 has a bottomed cylindrical shape or a bottomed substantially cylindrical shape, and is formed of a resin such as polyethylene terephthalate, or a metal such as aluminum or tinplate. The appearance of the storage part 11 can be transparent, translucent or opaque. The shape of the bottom may be as long as it can stand, and examples thereof include a flat shape, a concave shape, and a five-petal shape. The outer side surface of the storage portion 11 is preferably provided with a display for allowing the user to recognize that the liquid immersion tube 30 is bent and the opposite side of the direction in which the front end 30a faces is the front side. For example, by the position of P on the outer side of the storage part 11 , printing and displaying the display of the front direction F, etc., the user can recognize that the liquid immersion tube 30 is bent and the opposite side of the direction in which the front end 30a faces is the front side. The display indicating the front direction F can be, for example, a text or a pattern, but if it is a pattern that is consistent with the pattern printed on the actuator 20 when the ejection port 21 faces the front direction F, the design will not be impaired, and it can be used. The reader recognizes the frontal direction F. Here, the so-called front direction F refers to the preferred direction in which the ejection port 21 faces during use, and refers to the direction on the opposite side of the bending direction of the liquid immersion tube 30 to be described later. By orienting the ejection port 21 toward the front direction F indicated by the display P, even in the state where there are few enclosed objects in the post-use period of the quantitative ejection aerosol 100 for space treatment, if the pressure-resistant container 10 is slightly inclined upward with respect to the horizontal plane H, If the direction is inclined, the aerosol collagen solution and the propellant can be accumulated in the vicinity of the front end 30 a of the liquid immersion tube 30 . As a result, when the quantitative spray aerosol 100 for spraying space processing is sprayed, the liquid immersion tube 30 can effectively suck up the aerosol collagen liquid and the propellant, and it is possible to suppress the occurrence of ejection failure. The term "injection failure" here means a state in which the actual injection volume does not reach 85% of the injection volume of the quantitative injection valve 12 by one operation of the actuator 20 . In the case where the storage portion 11 is made of transparent or translucent resin, it is preferable to further print a horizontal display such as horizontal stripes on the storage portion 11 . The horizontal display is provided so as to prevent excessive inclination that may cause poor spraying when the quantitative spraying aerosol 100 for spraying space processing is sprayed. If there is such a level display, since the user will psychologically make the liquid level of the aerosol collagen liquid in the storage part 11 consistent with the level display, the quantitative spray aerosol 100 for space processing can be used in an appropriate posture.

The quantitative injection valve 12 is installed at the mouth of the storage part 11 , is connected to the actuator 20 on the outside of the pressure-resistant container 10 , and is connected to the liquid immersion pipe 30 on the inside of the pressure-resistant container 10 . The quantitative injection valve 12 has a valve mechanism (not shown), and is set so that the injection volume per injection is usually 0.2 to 5.0 mL.

(actuator) The actuator 20 is an actuating part for spraying the aerosol collagen solution. The actuator 20 is provided with a spray port 21 which is connected to the quantitative spray valve 12 and sprays the aerosol collagen solution from the pressure container 10 to the outside. Here, the angle of the injection port 21 will be described. 2 is an explanatory diagram showing (a) the elevation angle of the injection port (injection axis) and (b) the injection direction of the quantitative injection aerosol 100 for space treatment. In the present invention, the angle of the injection axis O of the injection port relative to the horizontal plane H when the pressure-resistant container 10 is placed on the horizontal plane H is defined as the elevation angle D ( FIG. 2( a )), and the quantitative injection for space processing is actually taken by hand. In the aerosol 100, the angle of the injection axis O of the injection port when the aerosol collagen solution is injected into the space with respect to the horizontal plane H is defined as the injection direction angle E (FIG. 2(b)). Therefore, the elevation angle D is basically an inherent angle of the quantitative spray aerosol 100 for space processing, and the spray direction angle E is an angle that varies with the spray posture. In the present invention, when the pressure-resistant container 10 is placed on the horizontal plane H, the elevation angle D of the jetting axis O relative to the horizontal plane H is set to 10-60°, more preferably 15-50°. When the elevation angle D is 10 to 60°, the aerosol collagen solution can be easily sprayed in the vicinity of 30 to 60° obliquely upward (that is, the spray direction angle E is 30 to 60°). If the elevation angle D is less than 10°, it is necessary to incline the pressure-resistant container 10 excessively in order to spray the aerosol collagen liquid in the vicinity of 30° to 60° obliquely upward with respect to the horizontal plane H. In this way, when the pressure-resistant container 10 is excessively tilted and sprayed, there may be problems. There is a risk of poor injection. When the elevation angle D exceeds 60°, the sprayed aerosol collagen liquid may adhere to the finger or the like operating the actuator 20 . In FIG. 2 , (a) the quantitative spray aerosol 100 for space processing is exemplified with the elevation angle D set to 60°, and (b) the quantitative spray aerosol 100 for space processing is inclined downward by 15°, and the spray direction angle E is set. It is in the state of 45°.

The number, shape, and size of the injection ports 21 are not particularly limited. The number of the injection ports 21 may be one, or may be two or more, but from the viewpoint of simplicity and low cost, the number of the injection ports 21 is preferably one. In addition, regarding a nozzle or an actuator having two ejection ports, the vertical bisector of the line segment connecting the centers of each ejection port 21 is defined as an ejection axis O, and regarding a nozzle or actuator having three or more ejection ports , the injection axis O of the injection port 21 is defined as follows. When the injection port 21 exists in the center of the injection part of a nozzle or an actuator, the orthogonal line which penetrates the center of the central injection port 21 is made into the injection axis O. In the case where the injection port 21 does not exist in the center of the injection part of the nozzle or the actuator, the injection axis O is defined as an orthogonal line passing through the center of the polygonal circumscribed circle connecting the centers of the injection ports 21 .

The shape (cross-sectional shape) of the ejection port 21 may be various irregular shapes other than a circle, an ellipse, a polygon, and the like. The opening area of the injection port 21 is preferably 0.05-8.0 mm ² , more preferably 0.1-4.0 mm ² , and still more preferably 0.2-3.0 mm ² . For example, when the number of the injection ports 21 is one and the shape of the injection ports 21 is circular, the size (orifice size) of the injection ports 21 is preferably 0.3 mm or more, more preferably 0.4 mm or more, and more preferably 0.6 mm above. Moreover, the nozzle diameter is preferably 3.0 mm or less, more preferably 2.0 mm or less, and still more preferably 1.8 mm or less.

The actuator 20 may or may not have a nozzle. In the case of having a nozzle, it may be a nozzle with a protrusion or a nozzle without a protrusion, but it is preferably a nozzle with a protrusion. In the case of an actuator with a nozzle, the length of the nozzle is not particularly limited, but is preferably 2.0 to 80 mm, more preferably 3.0 to 70 mm, and particularly preferably 4.0 to 60 mm. The operation button in the actuator 20 can be a push button or a trigger button.

(Liquid Immersion Tube) The liquid immersion tube 30 is a hollow member made of resin such as polyethylene or polypropylene attached to the quantitative injection valve 12. When the quantitative injection valve 12 is operated, the aerosol collagen liquid and the propellant enclosed in the pressure-resistant container 10 are supplied to the quantitative injection valve 12. Injection valve 12 . The liquid immersion tube 30 itself has a linear shape, but when it is attached to the quantitative injection valve 12 and inserted into the pressure-resistant container 10, it becomes bendable. Therefore, by properly bending the liquid immersion tube, the front end 30a of the liquid immersion tube can be easily arranged at an appropriate position in the pressure-resistant container 10 . The front end 30a of the liquid immersion pipe 30 is attached to the quantitative injection valve 12 so that the height h from the lowermost part B of the pressure vessel 10 is 6 mm or less, preferably 3 mm or less. Here, the lowermost part B of the pressure-resistant container 10 refers to the position closest to the horizontal surface H among the inner surfaces of the pressure-resistant container 10 when the pressure-resistant container 10 is placed on the horizontal surface H. As shown in FIG. In the case where the bottom surface of the pressure-resistant container 10 is dome-shaped as shown in FIG. 1 , the aerosol collagen liquid enclosed in the pressure-resistant container 10 exists in the lowermost part B in the later stage of use of the quantitative spray aerosol 100 for space treatment. Therefore, by arranging the front end 30a of the liquid immersion tube 30 at a distance of 6 mm or less from the lowest part B of the pressure-resistant container 10, even when the pressure-resistant container 10 is sprayed with a slight inclination relative to the horizontal plane H, the front end 30a is still located in the air The aerosol collagen solution and the propellant can be reliably supplied to the quantitative injection valve 12 under the liquid surface of the dissolved collagen solution and the propellant. As a result, it is possible to suppress the occurrence of ejection failure in the later stage of use of the quantitative ejection aerosol 100 for space processing. If the height h of the front end 30a from the lowermost part B of the pressure-resistant container 10 exceeds 6 mm, when the pressure-resistant container 10 is slightly inclined with respect to the horizontal plane H during spraying, the front end 30a is likely to be higher than the aerosol collagen liquid and the liquid level of the propellant. , as a result, there is a possibility that ejection failure will occur. The liquid immersion tube 30 preferably has a linear shape extending vertically downward when one end is installed on the quantitative injection valve 12, and vertically extends downward when one end is installed on the quantitative injection valve 12, and is bent at the curved portion 30b. shape, or a curved shape as a whole. More preferably, the front end 30a is located near the inner side surface S of the pressure-resistant container 10, and the curved portion 30b is bent, or the whole is bent. The liquid immersion tube 30 is in the shape of the curved portion 30b being bent, or the whole is in a curved shape. When the front end 30a is located near the inner side S of the pressure vessel 10, the distance d from the inner side S of the pressure vessel 10 to the front end 30a It is set to 25 mm or less, preferably 15 mm or less, more preferably 6 mm or less, and still more preferably 3 mm or less. By setting the distance d from the inner side surface S to the front end 30a to be 25 mm or less, even when the pressure-resistant container 10 is sprayed at an inclination with respect to the horizontal plane H, the aerosol collagen liquid located near the inner side surface S can be reliably supplied to the quantitative injection valve 12. And spraying agent, can inhibit the occurrence of poor spraying. The front end 30a of the liquid immersion tube 30 can be processed into various shapes. Fig. 3 is an enlarged cross-sectional view of the front end of a liquid immersion tube for quantitative spraying aerosol for space treatment, (a) illustrates an obliquely cut oblique end, (b) illustrates a U-shaped (concave) cut U end, (c) ) exemplifies the arc end portion of the arc-shaped (convex) cut, and (d) illustrates the right-angle end portion of the right-angle cut. Of these, (a) the oblique end portion of the oblique cut, (b) the U end portion of the U-shaped cut, or (c) the arc end portion of the arc-shaped cut is preferable. By making the front end 30a into such a shape, the upward suction of the aerosol collagen solution and the propellant becomes favorable, and the occurrence of ejection failure can be further suppressed.

<Aerosol Collagen Solution> For the aerosol collagen solution, a control component containing the following components as one of its main components can be used: (A) a compound whose vapor pressure at 30°C is less than 1×10 ^-4 mmHg (hardly volatile control component) ), (B) a compound with a vapor pressure of 2×10 ^-4 ~1×10 ^-2 mmHg at 30°C (volatile control ingredient), or a mixture of (A) and (B). Hereinafter, the aerosol collagen solution A which contains the less volatile control component and the aerosol collagen solution B which contains the volatile control component will be described.

[Aerosol Collagen Liquid A] As one of the main components of the aerosol collagen solution A, the non-volatile control component can be used as a creeping pest control compound for the control of creeping pests represented by cockroaches, bed bugs, ants, etc., and/or mainly used for indoor control Dust mites control compounds for dust mites.

If the quantitative spray aerosol 100 for space treatment of the present invention is sprayed in a certain amount in the treatment space in the room, the sprayed particles will mainly settle on the floor surface as adhesive particles. It shows excellent control effect on especially creeping pests or house dust mites. In addition, by containing the low-volatile control component, the less-volatile control component is suppressed from volatilizing into the atmosphere from the adherent particles deposited on the floor surface. Through such action mechanisms, the quantitative spray aerosol 100 for space treatment of the present invention has high safety and can be used even in a occupied situation.

Solvents, isopropyl myristate (IPM), hexyl laurate and other higher fatty acid esters with a carbon number of 16 to 20, glycol ether solvents with a carbon number of 3 to 10, and ketone-based solvents, etc. Among these, lower alcohols having 2 to 3 carbon atoms, hydrocarbon-based solvents, and higher fatty acid esters having 16 to 20 carbon atoms are preferred. In particular, lower alcohols with a carbon number of 2 to 3 are due to the uniformity of diffusion of spray particles or the exposed surfaces in the treatment space (for example, the floor surface or wall surface in the treatment space, the surface of structures such as furniture, etc.), especially It is not easy to produce stickiness on the floor surface, so it is better. The above-mentioned organic solvents may be used in combination of two or more.

In addition, if the specific gravity of the aerosol collagen solution A is in the above range, since the adherent particles also enter the gaps or hidden places in the process of sedimentation, when the pyrethrum-based compound is used as the control component, it is also expected that cockroaches can be fully expected. Wait for the flying effect of flying out of gaps or hidden places.

Examples of pest control compounds include metofluthrin, Profluthrin, transfluthrin, empenthrin, Terallethrin, and fenfluthrin Esters (furamethrin) and the like. Among these, in consideration of vapor pressure, stability, basic insecticidal efficacy, etc., metofluthrin, profluthrin, and transfluthrin are preferable. In the acid component or alcohol moiety of these compounds, optical isomers or geometric isomers based on asymmetric carbon may exist, and each of these or any mixture thereof is also included in the volatile control component. If the quantitative spray aerosol 100 for space treatment of the present invention is sprayed in a certain amount in the treatment space in the room, the spray particles containing the volatile control components will mainly settle as adhesive particles and adhere to the exposed surface of the treatment space (for example, exist in the treatment space) The floor surface or wall surface in the space, the surface of the structure such as furniture, etc.), especially the floor surface, and in the treatment space, it shows an excellent control effect on flying pests, creeping pests or house dust mites.

The content of the control ingredient in the aerosol collagen solution B is 1~90w/v%, more preferably 5~80w/v%, and still more preferably 8~75w/v%. When the content of the control component in the aerosol collagen solution B is in the above range, the control component is easily dissolved in the organic solvent, and when the aerosol is sprayed, the sprayed particles are formed in an optimum state.

＜Propellant＞ Examples of propellants used in the quantitative spray aerosol 100 for space treatment of the present invention include liquefied petroleum gas (LPG), dimethyl ether (DME) and hydrofluoroolefin, as well as nitrogen gas, carbon dioxide gas, nitric oxide and Compressed gas such as compressed air. The above-mentioned propellants can be used alone or in a mixed state, but those containing LPG as the main component are easy to use.

In the quantitative spray aerosol 100 for space treatment of the present invention, the volume ratio (a/b) of the aerosol collagen solution (a) and the spray agent (b) filled in the pressure-resistant container 10 is preferably adjusted to 10 in terms of volume ratio /90~50/50. When the capacity ratio (a/b) is in the above-mentioned range, a sufficient amount of the control component can be uniformly diffused to the entire exposed surface, especially the entire floor surface.

In the quantitative spraying aerosol 100 for space treatment of the present invention, the spraying force of the part with a distance of 5 cm from the spraying port 21 is preferably 5-50 gf.

Based on Examples 1 to 49 and Comparative Examples 1 to 7, the quantitative spray aerosol for space treatment of the present invention was further examined in detail. In order to confirm the effect of the quantitative spray aerosol for space treatment of the present invention, quantitative spray aerosols for space treatment having the characteristic structure of the present invention (Examples 1 to 49) were produced, and spray tests were carried out. Then, for comparison, quantitative spray aerosols for space treatment (Examples 1 to 7) not having the characteristic structure of the present invention were produced, and the same effect confirmation test was carried out.

[Example 1] An aerosol collagen solution A was prepared by dissolving fenothrin (40w/v%) as a less volatile control component in ethanol. 3.5 mL of the aerosol collagen solution A and 5.3 mL of liquefied petroleum gas as a propellant were pressurized and filled into a pressure-resistant container with a quantitative spray valve with a spray capacity of 0.4 mL. This filling amount is theoretically capable of performing quantitative injection up to 22 times. An actuator with a spray port is installed on the quantitative spray valve of the pressure-resistant container. When the pressure-resistant container is placed on a horizontal plane, the spray axis is at an elevation angle (D) of 60° with respect to the horizontal plane. Example 1 is obtained. Quantitative jet aerosol for space treatment. In the quantitative spray aerosol for space treatment in Example 1, the liquid immersion tube is cut with a U-shaped front end, and is installed in the pressure-resistant container so that the height (h) between the front end and the lowermost part of the pressure-resistant container becomes 1 mm. for quantitative injection valves. The spray force of the quantitative spray aerosol for space treatment in Example 1 is 15gf at a spray distance of 5cm.

[Examples 2 to 24, Comparative Examples 1 to 5] Based on Example 1, and with the configurations shown in Table 1, various quantitative spray aerosols for space treatment of Examples 2 to 24 and Comparative Examples 1 to 5 were produced. The quantitative spray aerosol for space treatment in Examples 16, 17, 21, 22, 23, and 24 uses a quantitative spray valve with a spray volume of 0.2 mL or 1.0 mL. In theory, a maximum of 22 quantitative sprays can be performed. way to adjust the filling amount of the pressure-resistant container.

<Spray test (spray angle 45°)> The quantitative spray aerosols for space treatment of Examples 1 to 24 and Comparative Examples 1 to 5 were fixed so that the spray axis of the spray port was at a spray angle of 45° with respect to the horizontal plane, and the spray was repeated. Before starting the calculation of the number of injections, carry out 2 empty shots, and then calculate the number of injections until the normal injection cannot be performed. In addition, in this embodiment, the so-called "incapable of normal injection" is synonymous with the aforementioned "injection failure", which means that the actual injection volume due to the operation of the actuator does not reach 85% of the injection volume of the quantitative injection valve. The same applies to the following examples. The test was repeated four times for each quantitative spray aerosol for space treatment, and the effect of suppressing spray failure was evaluated according to the following evaluation criteria corresponding to the average value of the number of sprays. (Evaluation Criteria) A: More than 18 times B: 16 or 17 times C: 14 or 15 D: less than 14 times

In addition, if the ejection failure occurred in one or more of the four tests until the second time from the start of the calculation, it was determined that there was ejection failure in the initial stage of use. The test results are shown in Table 1.

As a result of the test, in the case of spraying the agent at an angle of 45° above the horizontal plane, the quantitative spray aerosols for space treatment in Examples 1 to 24 were more than 14 times until they could not be sprayed normally.

In addition, the quantitative spray aerosols for space treatment of Examples 1 to 24 did not experience spray defects in the initial stage of use.

On the other hand, in Comparative Examples 1 to 5, the quantitative spray aerosols for space treatment were 13 times or less until they could not be sprayed normally, and the occurrence of spray failure in the later period of use was not sufficiently suppressed. In addition, the quantitative spray aerosols for space treatment of Comparative Examples 1 to 3 and 5 also had poor spraying in the initial stage of use.

The test was repeated four times for each quantitative spray aerosol for space treatment, and the effect of suppressing spray failure was evaluated according to the following evaluation criteria corresponding to the average value of the number of sprays. (Evaluation Criteria) A: More than 18 times B: 16 or 17 times C: 14 or 15 D: less than 14 times

In addition, if the ejection failure occurred in one or more of the four tests until the second time from the start of the calculation, it was determined that there was ejection failure in the initial stage of use. The test results are shown in Table 2.

The test results show that in the case of spraying the agent at an angle of 30° above the horizontal plane, the quantitative spraying aerosols for space treatment in Examples 25 to 32 are more than 15 times until they cannot be sprayed normally. Occurrence is inhibited. Among them, when the pressure-resistant container is placed on the horizontal plane, the actuator for setting the ejection port so that the ejection axis is at an elevation angle of 50° or less with respect to the horizontal plane is installed. The effect of suppressing poor ejection in the later period of use is particularly excellent. In addition, the quantitative spray aerosols for space treatment of Examples 25 to 32 did not experience spray defects in the initial stage of use.

In contrast, the quantitative spraying aerosols for space treatment in Comparative Examples 6 and 7 were less than 14 times until they could not be sprayed normally, and the effect of suppressing poor spraying in the later period of use was higher than that of the quantitative spraying for space treatment in Examples 25 to 32. Aerosols are worse. In addition, the quantitative spray aerosols for space treatment of Comparative Examples 6 and 7 also had poor spray at the initial stage of use.

Otherwise, by the same procedure as the quantitative spray aerosol for space treatment of Example 1, the quantitative spray aerosol for space treatment of Example 33 was obtained.

[Examples 34 to 38] Taking Example 33 as the criterion, and with the configurations shown in Table 3, various quantitative spray aerosols for space treatment of Examples 34 to 38 were produced.

<Spray test (spray angle 60°)> The quantitative spray aerosol for space treatment of Examples 33 to 38 was fixed in such a way that the spray axis of the spray port was at a spray angle of 60° with respect to the horizontal plane, and the spray was repeated. Before starting the calculation of the number of injections, carry out 2 empty shots, and then calculate the number of injections until the normal injection cannot be performed. The test was repeated four times for each quantitative spray aerosol for space treatment, and the effect of suppressing spray failure was evaluated according to the following evaluation criteria corresponding to the average value of the number of sprays. (Evaluation Criteria) A: More than 18 times B: 16 or 17 times C: 14 or 15 D: less than 14 times

In addition, if the ejection failure occurred in one or more of the four tests until the second time from the start of the calculation, it was determined that there was ejection failure in the initial stage of use. The test results are shown in Table 3.

Occurrence is inhibited. Among them, when the pressure-resistant container is placed on the horizontal surface, the actuator for setting the ejection port so that the ejection axis is at an elevation angle of 40 to 50° with respect to the horizontal surface is installed. , and the effect of suppressing poor ejection in the later period of use is particularly excellent. In addition, the quantitative spray aerosols for space treatment of Examples 33 to 38 did not experience spray defects in the initial stage of use.

[Example 39, 40] Based on Example 1, and with the constitution shown in Table 4, various quantitative spray aerosols for space treatment of Examples 39 and 40 were produced. In the case of the quantitative spray aerosol for space treatment of Examples 39 and 40, when a quantitative spray valve with a spray volume of 0.2 mL or 2.0 mL is used, the filling of the pressure-resistant container can also be adjusted in a way that theoretically a maximum of 22 quantitative sprays can be performed. quantity.

<Diffusion Uniformity Test> Glass plates of 20×20 cm were installed at 6 to 8 places on the floor of a closed house with a volume of 25 m ³ (area 10 m ² , height 2.5 m). In such a way that the spray axis of the spray port is at a spray angle of 45° with respect to the horizontal plane, the quantitative spray aerosols for space treatment of Examples 13 to 17, 39 and 40 are kept at a position of 1.5m in the center of the house, and a certain amount of spray is carried out. spray treatment. After 1 hour from the spray treatment, all the glass plates were taken out, the control components adhering to each glass plate were washed out with acetone, and analyzed by a gas chromatograph. For the control component adhering to the glass plate, the deviation between the glass plates was analyzed, and the diffusion uniformity of the sprayed particles was evaluated. The results are shown in three stages of A, B, and C in order from those with good diffusion uniformity. Furthermore, the above-mentioned spray test (the spray angle of 45°) was carried out with respect to the quantitative spray aerosols for space treatment of Examples 39 and 40. The test results of the spray test (spray angle 45°) and the diffusion uniformity test are shown in Table 4.
