FIG. 3 is an enlarged cross-sectional view of the tip of the dip tube of the quantitative injection aerosol for spatial treatment.

Hereinafter, the quantitative injection aerosol for spatial 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 the quantitative injection aerosol 100 for spatial treatment of the present invention. The fixed-quantity injection aerosol 100 for space treatment is provided with a pressure-resistant container 10 provided with a fixed-quantity injection valve 12 in which an aerosol stock solution containing a control component and an injection agent are sealed, and an injection port 21 connected to the fixed-quantity injection valve 12. The actuator 20 is provided with a dip tube 30 that supplies the undiluted aerosol solution and the propellant to the fixed-quantity injection valve 12, and by spatial treatment, flying pests such as mosquitoes and flies, pests such as cockroaches, indoor dust mites, etc. Used to control pests.

[Pressure-resistant container]
The pressure-resistant container 10 includes a storage unit 11 in which the aerosol stock solution and the propellant are stored, and a fixed-quantity injection valve 12 attached to the mouth of the storage unit 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 tin. The appearance of the reservoir 11 may be transparent, translucent, or opaque. The shape of the bottom may be upright, and examples thereof include a flat shape, a concave shape, and five petal-like shapes. It is preferable that the outer surface of the storage portion 11 is provided with a display for the user to recognize that the dip tube 30 is curved and the opposite side in the direction toward the tip 30a is the front surface. For example, it is used that the dip tube 30 is curved and the opposite side in the direction toward the tip 30a is the front surface because a display indicating the front direction F is printed at the position P on the outer surface of the storage unit 11. Can be recognized by a person. The display indicating the front direction F may be, for example, a character or a design, but if the design matches the pattern printed on the actuator 20 when the injection port 21 is directed toward the front direction F, the display may be used. It is possible to make the user recognize the front direction F without impairing the design. Here, the front direction F is a direction in which the injection port 21 is preferably directed at the time of use, and is a direction opposite to the bending direction of the dip tube 30 described later. By pointing the injection port 21 toward the front direction F indicated by the display P, the pressure-resistant container 10 is tilted slightly diagonally upward with respect to the horizontal plane H even when the amount of inclusions is small in the later stage of use of the spatial treatment quantitative injection aerosol 100. Then, the aerosol stock solution and the propellant will be accumulated in the vicinity of the tip 30a of the dip tube 30. As a result, when the quantitative injection aerosol 100 for spatial treatment is injected, the suction of the aerosol stock solution and the propellant by the dip tube 30 is improved, and the occurrence of injection failure can be suppressed. Here, the "injection defect" means a state in which the capacity actually injected by one operation of the actuator 20 is less than 85% of the injection capacity of the fixed quantity injection valve 12. When the storage unit 11 is made of a transparent or translucent resin, it is preferable that the storage unit 11 is further printed with a horizontal display such as a border pattern. The horizontal display is provided to prevent excessive tilting that causes injection failure when the quantitative injection aerosol 100 for spatial treatment is injected. With such a horizontal display, the user psychologically tries to adjust the liquid level of the aerosol stock solution inside the reservoir 11 to the horizontal display, so that the quantitative injection aerosol 100 for spatial treatment is used in an appropriate posture. be able to.

The metering injection valve 12 is attached to the mouth of the storage unit 11, is connected to the actuator 20 on the outside of the pressure-resistant container 10, and is connected to the dip tube 30 on the inside of the pressure-resistant container 10. The fixed-quantity injection valve 12 has a valve mechanism (not shown), and is usually set so that the injection capacity per injection is 0.2 to 5.0 mL.

[Actuator]
The actuator 20 is an operating unit for injecting the undiluted aerosol solution, and the actuator 20 is provided with an injection port 21 which is connected to the metering injection valve 12 and ejects the undiluted aerosol solution from the pressure-resistant container 10 to the outside. Here, the angle of the injection port 21 will be described. FIG. 2 is an explanatory diagram showing (a) an elevation angle of an injection port (injection shaft) and (b) an injection direction in a quantitative injection aerosol 100 for spatial treatment. In the present invention, the angle of the injection shaft O of the injection port with respect to the horizontal plane H when the pressure-resistant container 10 is placed on the horizontal plane H is defined as an elevation angle D (FIG. 2A), and the quantitative injection aerosol 100 for spatial treatment is actually used. The angle of the injection shaft O of the injection port with respect to the horizontal plane H when the aerosol stock solution is injected toward the space is defined as the injection direction angle E (FIG. 2B). Therefore, the elevation angle D is basically an angle peculiar to the quantitative injection aerosol 100 for spatial processing, and the injection direction angle E is an angle that varies depending on the injection posture. In the present invention, when the pressure-resistant container 10 is placed on the horizontal plane H, the elevation angle D of the injection shaft O with respect to the horizontal plane H is set to 10 to 60 ° and 15 to 50 ° in the injection port 21. Is preferable. When the elevation angle D is 10 to 60 °, the aerosol stock solution can be easily sprayed toward the vicinity of diagonally upward 30 to 60 ° (that is, the injection direction angle E is 30 to 60 °). If the elevation angle D is less than 10 °, it is necessary to excessively tilt the pressure-resistant container 10 in order to inject the aerosol stock solution diagonally upward to the vicinity of 30 to 60 ° with respect to the horizontal plane H. If the spray is tilted excessively, injection defects may occur. If the elevation angle D exceeds 60 °, the sprayed aerosol stock solution may adhere to the fingers or the like that operate the actuator 20. In FIG. 2, (a) the spatial treatment quantitative injection aerosol 100 in which the elevation angle D is set to 60 °, and (b) the spatial treatment quantitative injection aerosol 100 are tilted downward by 15 ° to set the injection direction angle E to 45. The state set to ° is illustrated.

The number, shape, and size of the injection ports 21 are not particularly limited. The number of injection ports 21 may be one or two or more, but from the viewpoint of simple and low cost manufacturing, the number of injection ports 21 may be one. preferable. For nozzles or actuators with two injection ports, the perpendicular bisector of the line segment connecting the centers of each injection port 21 is the injection axis O, and for nozzles or actuators with three or more injection ports. The injection shaft O of the injection port 21 is defined as follows. If the injection port 21 is located in the center of the injection portion of the nozzle or actuator, the orthogonal line penetrating the center of the injection port 21 at the center is defined as the injection axis O. If the injection port 21 does not exist in the center of the injection portion of the nozzle or actuator, the orthogonal line penetrating the center of the polygonal circumscribed circle connecting the centers of the injection ports 21 is defined as the injection axis O.

The shape (cross-sectional shape) of the injection port 21 may be a circular shape, an elliptical shape, a polygonal shape, or any other irregular shape. The opening area of the injection port 21 is preferably 0.05 to 8.0 mm ² , more preferably 0.1 to 4.0 mm ² , and further preferably 0.2 to 3.0 mm ² . preferable. For example, when the number of injection ports 21 is one and the shape of the injection ports 21 is circular, the size (injection port diameter) of the injection ports 21 is preferably 0.3 mm or more, preferably 0.4 mm or more. It is more preferably present, and more preferably 0.6 mm or more. Further, the nozzle diameter is preferably 3.0 mm or less, more preferably 2.0 mm or less, and further preferably 1.8 mm or less.

The actuator 20 may have a nozzle or no nozzle. In the case of having a nozzle, the one with a protruding nozzle or the one with a non-protruding nozzle may be used, but the one with a protruding nozzle is preferable. 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. As the operation button in the actuator 20, a push-down type button or a trigger type button can be adopted.

[Dip tube]
The dip tube 30 is a hollow member made of a resin such as polyethylene or polypropylene attached to the fixed-quantity injection valve 12, and when the fixed-quantity injection valve 12 is operated, the aerosol stock solution and the propellant sealed in the pressure-resistant container 10 are quantified. It is supplied to the injection valve 12. Although the dip tube 30 itself has a linear shape, it can be curved when it is attached to the metering injection valve 12 and inserted into the pressure resistant container 10. Therefore, by appropriately bending the dip tube, the tip 30a thereof can be easily arranged at an appropriate position in the pressure-resistant container 10. The tip 30a of the dip tube 30 is attached to the metering injection valve 12 so that the height h from the lowermost portion B of the pressure resistant container 10 is 6 mm or less, preferably 3 mm or less. Here, the lowermost portion B of the pressure-resistant container 10 is a portion closest to the horizontal plane H on the inner surface of the pressure-resistant container 10 when the pressure-resistant container 10 is placed on the horizontal plane H. As shown in FIG. 1, even when the bottom surface of the pressure-resistant container 10 has a dome shape, the aerosol stock solution enclosed in the pressure-resistant container 10 exists at the bottom B until the end in the latter stage of use of the quantitative injection aerosol 100 for spatial treatment. Will be done. Therefore, since the tip 30a of the dip tube 30 is located at a position 6 mm or less from the lowermost portion B of the pressure-resistant container 10, the tip 30a is the aerosol stock solution even when the pressure-resistant container 10 is sprayed at a slight angle with respect to the horizontal plane H. And because it is located below the liquid level of the propellant, the aerosol stock solution and the propellant can be reliably supplied to the fixed quantity injection valve 12. As a result, it is possible to suppress the occurrence of injection defects in the late use of the quantitative injection aerosol 100 for spatial treatment. When the height h of the tip 30a from the lowermost portion B of the pressure-resistant container 10 exceeds 6 mm, the tip of the pressure-resistant container 10 from the liquid surface of the aerosol stock solution and the propellant when the pressure-resistant container 10 is tilted slightly with respect to the horizontal plane H at the time of injection. 30a tends to be in a high position, and as a result, injection defects may occur. The dip tube 30 has a linear shape that extends in the downward vertical direction with one end attached to the fixed-quantity injection valve 12, and the dip tube 30 extends in the downward vertical direction with one end attached to the fixed-quantity injection valve 12 and curves in the curved portion 30b. It is preferable that the shape is curved or the whole is curved. Among them, it is more preferable that the curved portion 30b has a curved shape or a curved shape as a whole so that the tip 30a is located in the vicinity of the inner side surface S of the pressure resistant container 10. When the dip tube 30 has a curved shape at the curved portion 30b or a curved shape as a whole and the tip 30a is located in the vicinity of the inner surface S of the pressure-resistant container 10, the inner side surface S to the tip 30a of the pressure-resistant container 10 is located. The distance d is set to be 25 mm or less, preferably 15 mm or less, more preferably 6 mm or less, still more preferably 3 mm or less. Since the distance d from the inner surface S to the tip 30a is 25 mm or less, the aerosol stock solution and the propellant in the vicinity of the inner surface S can be reliably sprayed even when the pressure-resistant container 10 is sprayed at an angle with respect to the horizontal plane H. It can be supplied to the fixed-quantity injection valve 12 to further suppress the occurrence of injection defects. The tip 30a of the dip tube 30 can be processed into various shapes. FIG. 3 is an enlarged cross-sectional view of the tip of the dip tube of the quantitative injection aerosol for spatial treatment, in which (a) an obliquely cut oblique end portion and (b) a U-shaped (concave) cut end portion. , (C) The arc end portion cut into an arc shape (convex shape), and (d) the right angle end portion cut at a right angle are illustrated. Of these, (a) an obliquely cut oblique end portion, (b) a U-shaped cut U-end portion, or (c) an arc-shaped cut arcuate end portion are preferable. Since the tip 30a has these shapes, the aerosol stock solution and the propellant can be sucked up well, and the occurrence of spray failure can be further suppressed.

The undiluted aerosol solution has (A) a compound having a vapor pressure of less than 1 × 10 ^-4 mmHg (non-volatile control component) at 30 ° C. and (B) vapor at 30 ° C. as control components that are one of its main components. A compound having a pressure of 2 × 10 ^-4 to 1 × 10 ⁻² mmHg (volatile control component) or a mixture of (A) and (B) can be used. Hereinafter, a solution containing a refractory control component will be referred to as an aerosol stock solution A, and a solution containing a volatilization control component will be referred to as an aerosol stock solution B.

Among these, phenothrin, cyphenothrin, permethrin, cypermethrin, cyfluthrin, bifenthrin, phenpropatrin, tralomethrin, etofenprox, and dinotefuran are preferable. If optical isomers or geometric isomers based on asymmetric carbon are present in the acid component or alcohol portion of the pyrethroid compound, each of them or any mixture thereof is also included in the pest control compound. Examples of the tick control compound include amidoflumeth, benzyl benzoate, phenyl salicylate, benzyl salicylate, dibutyl sebacate, dipropyl sebacate, dibutyl adipate, diethyl phthalate, dipropyl phthalate, dibutyl phthalate, and p-menthan-3. , 8-diol, 3-iodo-2-propynylbutyl carbamate, phenotrin, DEET and the like.

In the quantitative injection aerosol 100 for spatial treatment of the present invention, when a certain amount is sprayed in an indoor treatment space, the spray particles mainly settle on the floor surface as adhesive particles, but the treatment is carried out by containing a refractory control component. It shows an excellent control effect especially against scab pests and indoor dust mites in space. In addition, by including the refractory control component, the volatilization of the refractory control component from the adherent particles settled on the floor surface into the air is suppressed. Due to such a mechanism of action, the quantitative injection aerosol 100 for spatial treatment of the present invention is highly safe and can be used even in the presence of a person.

The content of the control component in the aerosol stock solution A is 1 to 90 w / v%, preferably 5 to 80 w / v%, and more preferably 30 to 75 w / v%. When the content of the control component in the aerosol stock solution A is within the above range, the control component is easily dissolved in the organic solvent, and when the aerosol is sprayed, the jet particles are formed in an optimum state.

The aerosol stock solution A contains an organic solvent in addition to the above-mentioned control components. As the organic solvent, an aerosol stock solution A can be prepared by dissolving the above-mentioned control component, and a solvent capable of forming optimum jet particles when the prepared aerosol stock solution A is sprayed is used. In the quantitative injection aerosol 100 for spatial treatment of the present invention, the organic solvent includes, for example, ethanol, a lower alcohol having 2 to 3 carbon atoms such as isopropanol (IPA), a normal paraffin, and a hydrocarbon solvent such as isoparaffin. , Isopropyl myristate (IPM), hexyl laurate and the like, higher fatty acid esters having 16 to 20 carbon atoms, glycol ether solvents having 3 to 10 carbon atoms, ketone solvents and the like. Among these, lower alcohols having 2 to 3 carbon atoms, hydrocarbon solvents, and higher fatty acid esters having 16 to 20 carbon atoms are preferable. In particular, lower alcohol having 2 to 3 carbon atoms has a diffusion uniformity of spray particles and an exposed surface in the treatment space (for example, a floor surface or a wall surface existing in the treatment space, a surface of a structure such as furniture, etc.). This is particularly preferable because it does not easily cause stickiness on the floor surface. It is also possible to use a mixture of two or more of the above organic solvents. Further, as the organic solvent, it is also possible to further mix glycol ethers, hydrocarbon solvents such as normal paraffin and isoparaffin, and ketone solvents.

The specific gravity of the aerosol stock solution A is preferably 0.85 to 1.15, more preferably 0.89 to 1.10. When the specific gravity of the aerosol stock solution A is in the range of 0.85 to 1.15, when a fixed amount of the quantitative injection aerosol 100 for spatial treatment of the present invention is sprayed in the indoor treatment space, the spray particles are mainly used as adhesive particles on the floor. Since it settles and adheres to the surface, an appropriate control effect can be obtained. In addition, if the specific gravity of the aerosol stock solution A is within the above range, the adherent particles also enter gaps and shadows in the process of sedimentation. Therefore, when a pyrethroid compound is used as a control component, cockroaches and the like enter the gaps. You can also expect a flushing effect that pops out of the shadows.

In addition to the above components, the aerosol stock solution A contains an antifungal agent, an antibacterial agent, a bactericidal agent, an fragrance, a deodorant, a stabilizer, an antistatic agent, an antifoaming agent, and an addition.

Volatile control components, which are one of the main components of aerosol stock solution B, include flying pests such as mosquitoes and flies, pest insects such as cockroaches, bed bugs, and ants, and pests such as indoor dust mites. A pest control compound for controlling flies can be used. Examples of the pest control compound include metoflutrin, profluthrin, transfluthrin, empentrin, terraresulin, flamethrin and the like. Among these, metoflutrin, profluthrin, and transfluthrin are preferable in consideration of vapor pressure, stability, basal insecticidal efficacy, and the like. If optical isomers or geometric isomers based on asymmetric carbon are present in the acid component or alcohol moiety of these compounds, each of them or any mixture thereof is also included in the volatilization control component. When a fixed amount of the quantitative injection aerosol 100 for spatial treatment of the present invention is injected in an indoor treatment space, the spray particles containing the volatile control component are mainly treated as adhesive particles on an exposed surface in the treatment space (for example, in the treatment space). Excellent control effect against flying pests, spider pests and indoor dust mites in the treatment space where it settles and adheres to the floor surface, wall surface, surface of structures such as furniture, etc. Is shown.

The content of the control component in the aerosol stock solution B is 1 to 90 w / v%, preferably 5 to 80 w / v%, and more preferably 8 to 75 w / v%. When the content of the control component in the aerosol stock solution B is within 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.

The aerosol stock solution B contains an organic solvent in addition to the above-mentioned control components. As the organic solvent, an aerosol stock solution B can be prepared by dissolving the above-mentioned control component, and a solvent capable of forming optimum jet particles when the prepared aerosol stock solution B is sprayed is used.

In addition to the above components, the aerosol stock solution B contains an antifungal agent, an antibacterial agent, a bactericidal agent, an fragrance, a deodorant, a stabilizer, an antistatic agent, an antifoaming agent, and an addition. A shaping agent or the like can be appropriately blended. These additional components are the same as those added to the aerosol stock solution A described above.

[Mixture of aerosol stock solution A and aerosol stock solution B]
When the mixture of the above aerosol stock solution A and aerosol stock solution B is used as the aerosol stock solution (A + B), effective control against all of flying pests, pests and indoor dust pests becomes possible, and it is wider. It can be used for various purposes.

In the quantitative injection aerosol 100 for spatial treatment of the present invention, the volume ratio (a / b) of the aerosol stock solution (a) and the propellant (b) filled in the pressure-resistant container 10 is 10/90 to 50 / by volume. It is preferably adjusted to 50. When the volume ratio (a / b) is within the above range, a sufficient amount of the control component can be uniformly diffused over the entire exposed surface, particularly the entire floor surface.

The quantitative injection aerosol 100 for spatial treatment of the present invention preferably has an injection force of 5 to 50 gf at a position where the distance from the injection port 21 is 5 cm.
