CONSTITUTION:A plurality of jet apertures 2 are provided on the periphery of the barrel of a tubular body 1, and the tip of the body 1 is so shaped as to allow the tip to penetrate into a mat. In this case, the aperture can be provided, in the form of slit or hole, or in plural steps, on the periphery of the barrel. However, regardless of the form, each jet aperture 2 should be positioned in a direction where it crosses the longitudinal direction of the tubular body directly, and provided in a position corresponding to each layer which constitutes a mat.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tatami treatment tool suitable for exterminating pests and the like on tatami mats.

[Prior art and its problems] Conventionally, in order to exterminate pests and microorganisms on tatami mats, the tatami mats were raised and treated outdoors in direct sunlight without the use of chemicals, or chemicals such as insecticidal powders were used. Because insecticidal liquids were simply sprayed or applied onto the tatami mats, the insecticides did not fully penetrate into the tatami mats, making it impossible to obtain sufficient insecticidal effects. It is also possible to soak the chemicals in the tatami and spray them, but as the permeation and diffusion of the chemicals within the tatami is extremely insufficient, a satisfactory control effect cannot be achieved, and a product suitable for this type of use is desperately needed. It's here.

[Problems to be Solved by the Invention] The present invention has been completed as a result of intensive research aimed at improving the drawbacks of the prior art.

[Means for Solving the Problems] That is, the present invention is a tatami treatment tool that requires a tubular body for exterminating pests and microorganisms on tatami mats to be attached vertically to an aerosol container. The tip of the tubular body is substantially blind-shaped, and the nozzle holes are provided on the circumferential surface of the body of the tubular body in at least two or more stages in the longitudinal direction of the tubular body, and the nozzle holes in each stage are orthogonal to each other. The present invention relates to a light processing tool characterized in that it is provided at a position corresponding to each layer constituting a tatami mat.

[Operations and Examples] Since the present invention has the above-described structure, whenever it is necessary to perform chemical treatment on tatami mats, the tubular body (
It goes without saying that by simply inserting the tatami mat (hereinafter referred to as the main unit) and injecting the chemical, you can treat the tatami very easily while it is still laid, without having to take the trouble of raising it, or even if you do. The drug is dispersed in the tatami mat very well by multiple injections, and the nozzle holes are designed to match the internal structure of the tatami mat (JIS standard), so the drug can be predicted along the grain of the straw. It penetrates more than the
It is characterized in that the distribution of the drug is much more uniform than when simply spraying using a normal nozzle, and furthermore, it does not leave any sting marks on the main body when it is pulled out. Here, the JI

Various additives such as potency enhancers and desiccants (such as superabsorbent resins) may be used in the above-mentioned drugs as necessary.

In the present invention, the shape of the main body is such that the distal end portion is substantially blind-shaped, and the injection holes are provided on the circumferential surface of the body of the main body in at least two stages in the longitudinal direction of the main body, and the injection holes in each stage are orthogonal to each other. The nozzle holes are located at positions corresponding to the layers that make up the tatami mat, and the tip of the body can be easily inserted into the tatami mat from the front, back, or side. There are no restrictions on length, size, width, etc., but the length should be 4.3 to 4.7 cm, depending on the tatami standard (5 cm thick).
cm is preferable, and any thickness can be used as long as it does not leave puncture marks on the tatami mat when extracted.

Furthermore, the main body may be telescopic, bendable (including those having a rubber tube in the middle), detachable, removable, freely rotatable in the axial direction, or may be composed of a plurality of bodies. Materials that are compatible with these forms can be appropriately selected and used. By making it rotatable as described above, the position of the nozzle hole can be appropriately changed and used, which is advantageous because it enables spraying over a wide range. Furthermore, a fitting part for the push button may be provided at the base end of the main body, so that when using an aerosol, for example, it can be easily set by simply fitting it into an existing push button or jet tube. Although this is advantageous, it is also possible to provide a push button at the proximal end of the main body.

The area of the nozzle hole provided in the main body may be the same as or smaller than the inner diameter of the main body, and usually the nozzle hole diameter is 0.1 to 1.
l, in the range of Omm, preferably 0.3 to 0
, 61ars, and when a fitting portion or a push button is provided as described above, it is advantageous to satisfy the following relationship: nozzle hole diameter of push button≧inner diameter of main body≧nozzle hole diameter of main body to improve the spray condition.

However, if more uniformity is required in a weak spray state, separate installation is not required. The number of nozzle holes in the nozzle is determined from the above relationship.

The nozzle holes are provided in at least two or more stages in the longitudinal direction of the main body on the outer circumferential surface of the body, with the nozzle holes in each stage orthogonal to each other, and at positions corresponding to the respective layers constituting the tatami mat. In this case, the tatami can be processed with one touch. At this time, it is advantageous to provide the injection holes in a staggered manner, as shown in FIG. 3a, for example, since it is possible to treat a wider range of tatami mats.

In the present invention, as the injection mechanism applied to the main body, any type that is used for this type of application can be used, such as an aerosol type, a type using various pumps, and a type using a cylinder. , can be used in combination with a compressor, etc. as appropriate.

When using the above cylinder, the pressure is quite high, so
It is used by attaching it to a suitable spray gun. Other suitable auxiliary means may be adopted for the main body, for example, the tip of the main body can be attached and detached at an appropriate position in the longitudinal direction of the main body (of course, the proximal end is also possible) for safety when not in use. It can be used to adjust the degree of penetration of the main body into the bone when it is in use, and it can be used to adjust the degree of penetration of the main body into the bone when it is not in use. By moving the stopper toward the tip, stopping when the tip is no longer visible, and fixing the main body to the body with a set screw, the tip of the main body can be protected and injuries caused by misuse can be avoided (Figure 4). reference).

In addition, the tubular body can be stored in the container so that it can be moved in and out, and a part of the container is retracted, so that the tubular body can be used.When not in use, the main body is stored in the container. Although it is safe, the container may be equipped with a suitable stopper just to be safe.

Furthermore, instead of housing the device in the container, the main body itself may be used in combination with, for example, a bellows-shaped cover and a stopper to prevent the cover from shrinking.

In the present invention, the sprayer as one of the spray mechanisms described above may be an automatic spray type with an intermittent valve. In this case, if you set the main body of the sprayer toward the area where cockroaches are infested, such as the gap behind the tatami mat,
Aerosol can be automatically and intermittently sprayed to such cockroach-infested areas.

In the present invention, the hole diameters of the injection hole of the main body, the injection hole of the push button, and the valve stem are in the range of 0.3 to 0.6 mm, and the hole diameter of the injection valve housing and the hole diameter of the paper tap are 0.3 to 0.6 mm. The hole diameter is in the range of 3 to 0.5 mm, and the difference between the hole diameter of at least one of the injection valve housing and the dip tube and the hole diameter of the paper tap is within 0.1 mm. You can take it. In this case, as a filling liquid, when the active ingredient solution and propellant are combined, the active ingredient solution is 30%
~60% by volume can be advantageously used.

In the aerosol agents normally used in the royal market, the hole diameter of this housing is 0.7 to 1.5 mm, and the hole diameter of the dip tube is large, 1 to 3.5 mm.Compared to this, the hole diameter of the paper tap is 0.25 mm. ~0.4 mm, and the difference greatly exceeds 0.1 mm.If this is used in an inverted position, a large amount of propellant will be sprayed, and the ratio with the active ingredient solution in the aerosol container will be disrupted. By keeping this difference within 0.1 mm, for example, the effectiveness of insecticides will be uniform, and the propellant will run out first and only the active ingredient solution will remain without being sprayed. There is an advantage that the amount of injection per unit time for upright and inverted positions can be made almost the same.

The active ingredient solution referred to in the present invention is a solvent whose vapor pressure is substantially lower than the injection pressure at room temperature, such as hexane, 3.3.4-trimethylnonane, cyclohexane, kerosene, naphtha, Petroleum solvents such as normal paraffin, isoparaffin, and liquid paraffin; Chlorinated hydrocarbons such as dichloroethane and trichloroethane;
A solution of alcohols and ether derivatives such as ethyl alcohol, isopropyl alcohol, and ethylene glycol, as well as water, containing the aforementioned active ingredients such as pyrethroid insecticides such as allethrin, phthalthrin, permethrin, and phenothrin, and organic compounds such as DDVP and fenitrothion. Phosphorous insecticides, carbamate insecticides, synergists such as piveronyl butoxide, and deodorizing or deodorizing agents are dissolved as they are or emulsified with a surfactant.

In addition, as a propellant, for example, fluorocarbons (fluorocarbon-1
1, Freon-112, Freon-113, etc.), liquefied petroleum gas, dimethyl ether, etc. are used alone or in combination.

Next, the tatami treatment tool of the present invention will be explained in more detail based on Examples, but the present invention is not limited only to these Examples.

Examples 1 to 6 150 ml of kerosene solution containing pyrethroid insecticide permethrin 1.33% and 150 ml of liquefied petroleum gas
was filled into an aerosol container with an internal capacity of 390 m1, and
A valve was attached and sealed as shown in the table to obtain an aerosol agent for a tatami treatment tool of the present invention. A button was attached to this and the main body was connected, and a jetting test (30 seconds) was conducted.The difference between the upright and inverted positions was considered acceptable if it was within 10%, and acceptable if it was within 20%.

The results are also listed in Table 1.

[Left below] Examples 7 to 10 In Example 1, the propellant was 70 ml of dimethyl ether.
An aerosol agent for a tatami treatment tool of the present invention was obtained in the same manner as in Example 1, except that 80 ml of liquefied petroleum gas was used. A jetting test was conducted using the obtained aerosol agent. The results are shown in Table 2.

[Margins below] An example of the implementation of the different processing tool of the present invention will be described below. Figures 1a to lc are partially omitted sectional views showing an example of the different processing tool of the present invention, and Figures 2a to 2b are partially cutaway front views showing another example of the different processing tool of the present invention. 3a to 3b are cross-sectional views showing still another example of the different processing tool of the present invention, and FIG. 4 is a partially cutaway front view showing still another example of the different processing tool of the present invention. .

In Figures 1a to lc, Figures 2a to 2b, Figures 3a to 3b, and Figure 4, (1) is a main body;
A plurality of nozzle holes (2) are provided on the circumferential surface of the body of the body (
1) The tip has a shape that can be practically used as a tatami mat.

When in use, by connecting it to a suitable aerosol, cylinder, or other spraying means, and inserting it into the tatami mat to spray, the drug can be sprayed very well from the nozzle nozzle, as evidenced by the test results described below. It is possible to obtain a very good diffusion distribution state in the bone. In addition, the insecticidal effect has been very good, and it has a unique structure as an insecticidal tool for bones.

In the present invention, the arrangement and shape of the nozzle holes are limited to one on the circumferential surface of the body.
When it is provided only in one stage (see Figure 1a), when it is provided in multiple steps (see Figures 1C, 2a-2b, 3a-3b, and 4), In FIG. 1C, the lowest nozzle hole (2) is provided so as to spray diagonally downward, which is advantageous because it enables spraying over a wider area. Examples of cases in which vertical and horizontal slit-shaped nozzle holes are provided include the different treatment tools shown in FIGS. 1b and 2b.

Next, the shape of the main body (1) is such that the base end of the main body (1) is provided with a fitting part (which is advantageous because it is in the form of a cap, so it can be directly attached to a push button, etc.) that fits into the push button or spray barrel of the sprayer.
(see Figures 2a-2ti) or a push button (see Figures 3a-3b). In this case, as shown in Fig. 3a, when the main body (1) is attached to the stem of a normal sprayer and inserted into the tatami, the upper surface (4a) of the push button (4) becomes the pressing surface, so the surface of the tatami is pressed. It is easy to use because it can also be used as a surface, and the one shown in Fig. 3b is advantageous when the sprayer is used with the sprayer lying on its side.

In addition, the different processing tool shown in FIG.
A screw (5b) long enough to reach the circumferential surface (la) of the main body (1) is provided in the middle of the circumferential surface (5a) of the main body (1), so that the cover (5) can be stopped at an appropriate position. ing. In this case, by tightening the screw (5b) at a point where the tip of the main body (1) is hidden from the lower end of the tubular cover (5),
The tip of the main body (1) can be protected and the danger from its use can be removed, and since it is provided in a slidable manner, the depth of the nozzle's penetration (insertion) into the bone can be adjusted. This is advantageous because it allows you to

After 10 days had passed, 500+ng of the sample was taken out and the number of mites living there was observed using a stereomicroscope. The results are shown in Table 4. The results for the untreated plot are also shown in Table 4 as a control.

[Blank below] [Effects of the Invention] Since the present invention has the above-described structure, whenever it is necessary to treat tatami mats with chemicals, it is possible to simply insert the main body into the tatami mats and inject the medicine. It goes without saying that it is extremely easy to dispose of the tatami while it is laid out without raising it, and even if it is to be raised again.
- The drug spreads very well inside the tatami by multiple injections, and because the nozzle holes are arranged to match the internal structure of the tatami, the drug penetrates along the grain of the straw more than expected. Compared to simply spraying using a normal nozzle, the drug can be distributed much more uniformly, and when it is pulled out, it does not leave any sting marks on the main body.
