Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rat-proof, insect-controlling composition and mouse for aerosol sprays for double floors, ceilings and the like of buildings and the like, and an aerosol spray can for insect-controlling.

[0002]

2. Description of the Related Art In recent years, high-tech buildings such as intelligent buildings have been built one after another, and office buildings are air-conditioned throughout the year, especially in buildings with restaurants and trading companies that handle food. The air-conditioning under the double-floor without natural enemies is a good living environment, and it becomes a habitat for insects such as rats and cockroaches, and breeding places for these small animals (breeding of rodents twice in spring and autumn / year, here Like humans,
It is said that the number of people is increasing in the calculation method for the whole year), and even if the traffic lights of trains and trains of financial institutions stop or the lights of underground cities go out all at once, that is "damage from rats". It is said that, because it is an image down, it will go underground without being announced and will be buried with underground information. For this reason, it is considered that what has been conventionally picked up by the media, such as newspapers, is only a part of the damage that is actually occurring. Conventionally, wild mice that live outdoors in forests, etc.
There is creosote oil as a repellent against cockroaches, white spots, etc., and as a repellent against domestic rats, cockroaches, etc., cycloheximide or capsaicin is a micro-encapsulated taste repellent, insecticide (adhesive tape There is). Creosote oil has a strong pungent odor and cannot be used indoors as it is. Cycloheximide or capsaicin microencapsulated taste repellent is kneaded into resin and is used for coating electric wires, etc., and rodents that have bitten the electric wire have no subsequent bite effect, but they are due to taste. , The effect is limited to the rodents, and there is no effect of cleaning the rats from under the floor such as high-tech buildings.
In addition, it is expensive because it is microencapsulated. Rodenticides or insecticides are extremely unsanitary because the carcasses such as mice and cockroaches are troublesome to treat and are left as they are. As described above, no effective repellent is provided at present. In particular, there is not provided a rodent-proof or insect-repellent composition for aerosol spray which can be used immediately and has an immediate effect for several days.

Although aerosol packaging has a long history, it has been widely used for household and industrial use since the Second World War, especially recently, aerosol sprays have been used very much and various kinds of contents have been used. There is a wide variety. Among these contents, paints and insecticides are particularly common, but none for rodent protection. Most spray cans are used in an upright position with the injection port facing up, and the structure of the can is also shown in FIG.
As shown in, a dip tube is fitted into the introduction tube connected to the actuator. As a special one, there is a spray can that is used upside down by utilizing the movement of metal balls, but the structure is complicated and expensive.
In particular, there is no inexpensive spray can with a simple structure that can be sprayed even when it is upside down, which is convenient to use in a space where a spray can, such as a double floor, cannot be placed in an upright position.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems, can be used immediately, has immediate effect, and is effective for about 1 week, and also has a rodent for aerosol spray, a composition for insect repellent, and an inverted state. However, it is an object to provide an aerosol spray can for rats and insects which can be sprayed, has a simple structure and is inexpensive.

[0005]

The above-mentioned problems are solved by adding aerosol of 8 to 30 parts by volume of acacia oil or 5 to 15 parts by volume of abacus oil and soy sauce brain oil to 100 parts by volume of isopropyl alcohol of the first invention of the present application. Rodent for spraying,
Insect repellent having a composition for insect repellent and a sleeve for closing an opening in an introduction pipe connected to an actuator in an aerosol spray can of the second invention and closing the opening by moving the opening and the can depending on whether the can is upright or inverted. Solved with an insect repellent aerosol spray can.

The aroma oil used in the first invention of the present application is a colorless or slightly yellow transparent liquid obtained by cooling the oil obtained by steam-distilling the above-ground portion of the abacus, which is a perennial plant of the family Lipidae, and removing solids. is there.

The camphor oil used in the first invention of the present application is a colorless or slightly yellow transparent part of the distillate fraction of natural camphor oil made by distilling roots, leaves and stems of camphor tree. Is a liquid.

The isopropyl alcohol used in the first invention of the present application is selected from the solubility of acacia oil and camphor oil and the solubility with a propellant.

As the propellant used in the first invention of the present application,
Both liquefied gas and compressed gas can be used, but each has its own characteristics. The advantage of liquefied gas such as Freon 134a, LPG, and dimethyl ether is that it maintains a substantially constant pressure during injection, the injection characteristics do not change, and the remaining amount in the container is small. Disadvantageously, the change with temperature is large, the temperature drops during injection, and it is not suitable for continuous injection for a long time and is expensive. The advantages of compressed gas such as carbon dioxide gas are that the temperature change is small and the temperature range is wide, the amount of propellant is small and the cost is low.
Disadvantageously, the type of injection is limited because it is difficult for the injection particles to become fine. In addition, as the amount of the content is reduced, the injection pressure decreases, and residual liquid is likely to be generated in the container. Further, if the usage is wrong, only the gas may be injected. In the first invention of the present application, chlorofluorocarbon 134a is particularly preferable in view of these advantages and disadvantages, solubility with isopropyl alcohol, aroma oil and soy sauce oil, and avoidance of destruction of the ozone layer.

Freon 134a is a fluorocarbon containing hydrogen and is a nonflammable liquid having a chemical formula of CH ₂ FCF ₃ boiling point of −26 ° C.

In the first invention of the present application, 8 to 30 parts by volume of acacia oil or 5 to 15 parts by volume of acacia oil and soy sauce oil are added to 100 parts by volume of isopropyl alcohol. When using mackerel oil alone against isopropyl alcohol, the repellent effect is reduced if it is less than 8 parts by volume with respect to the rat, even if it exceeds 30 parts by volume, it cannot be expected so much and it is uneconomical. Become. The combination of acacia oil and soy sauce oil also has the same tendency as the case of using acacia oil alone, and a synergistic effect of repelling property due to the combination can be expected between 5 to 15 parts by volume.

Next, a mouse and insect repellent aerosol spray can according to the second invention of the present application will be described. As mentioned above, conventional spray cans using aerosols such as paints and pesticides are used in an upright state.Due to the structure of the double floor, the spray cans should not be inverted during operation to spray below the floor. And it doesn't scatter enough until I put it under the floor. For this reason, the second invention of the present application is such that even when used in an inverted state, it can be sufficiently scattered up to under the floor as in the case of being used in an upright state. As shown in FIGS. 1 and 2, an opening 4 is provided in an introduction pipe 3 connected to an actuator 2 of an aerosol spray can 1 for rodent protection and insect control, and the introduction pipe 3 is provided.
The sleeve 5 is fitted in the. In the upright state shown in FIG. 1, the sleeve 5 falls to the position of the stopper 6 provided on the introduction tube 3 by its own weight and closes the opening 4. When sprayed in this state, the content moves from the lower end of the tube 7 following the introduction tube 3. Then, it is ejected from the ejection port 8. A packing 9 is fitted between the stopper 6 and the sleeve 5 so as to more reliably prevent the contents from entering from below the sleeve 5, and to prevent the contents from entering from above the sleeve 5, the upper end of the sleeve 5 and the opening. This is dealt with by making the interval between the parts 4 longer.

In the inverted state shown in FIG. 2, the sleeve 5 descends to the end of the introduction tube 3 on the actuator 2 side by its own weight, and the opening 4 is released. When spraying in this state, the contents enter from the opening 4 and the injection port 8 Is jetted from.

The aerosol spray can used for the rodent-proof and insect-control aerosol spray can 1 according to the second invention of the present application can be the one conventionally used for aerosol spray cans of insecticides and the like, and the sleeve 5 and the stopper 6 are newly added. Should be provided.

The sleeve 5 fitted into the introduction pipe 3 is preferably made of metal such as stainless steel in terms of weight and rust. Sleeve 5
The pipe diameter may be slightly larger than the outer diameter of the introducing pipe 3 and can be moved along the introducing pipe 3 by its own weight. The contents infiltrate into the gap between the sleeve 5 and the introduction pipe 3 to act as lubricating oil, and the movement of the sleeve 5 is smooth. Sleeve 5
Is a length that completely closes and releases the opening 4 provided in the introduction tube 3.

The stopper 6 provided on the introduction tube 3 may be any one that can stop the movement of the sleeve 5 by providing metal or synthetic resin or the like by an appropriate means such as welding adhesion.

As the packing 9 fitted between the sleeve 5 and the stopper 6, an elastic solvent-resistant resin, for example,
Silicone, Teflon, etc. can be used.

The opening 4 provided in the introduction tube 3 is determined by the ease of movement of the contents, the strength, and the relation of blocking by the sleeve 5.

[0019]

In the first aspect of the present invention, isopropyl alcohol, acacia oil and camphor oil are easily dissolved in each other, so that they can be uniformly sprayed as an aerosol by a propellant from an aerosol spray can. Fluorocarbon 134 as a propellant
When a is used, the flon 134a has good solubility with isopropyl alcohol, acacia oil and soy sauce brain oil, so the aerosol sprayed from the aerosol spray can becomes a very fine and uniform mist, which is a repellent acacia oil and soup. Carry brain oil. Double floors are usually constructed on a concrete floor. The surface layer of a concrete floor has numerous micropores that are traces of excess water vaporized by the hydration reaction that occurs when cement paste is cast. The acacia oil and camphor oil carried in the form of fine and uniform atomized aerosol are adsorbed by the fine pores. Therefore, the concentration of the repellent in the space under the double flooring is effectively maintained for a long time. For example

[Residual rate of ambient concentration by spraying] A space (height 10 cm) under a wide double-floor material is divided into 5 × 10 (m) with a filler (product name: Nytobo Co., Ltd., product name: Tycalock). The rat-proof and insect-control aerosol spray cans of the present invention shown in FIG. 1 contain 40% by volume of isopropyl alcohol, 5% by volume of capsular oil, 5% by volume of camphor oil, and Freon 134a50.
Enclose the volume%, invert the can from the double floor material notch (85 mm square), and at 20 ° C, approximately 3.5 kg / cm
^{It is} jetted for 5 seconds at a pressure of ² (gauge pressure), and the air under the double floor material is sampled from the notch (85 mm square) 5 m away from the injected notch and the repellent gas concentration is measured by gas chromatography. A graph of the concentration over time is shown in FIG. Since the measured values were not stable immediately after injection, the initial measurement was made after half a day.

As shown in the graph of FIG.
After 8 days, 0 ppb remains at 50 ppb, which is 20% of the initial concentration. Next, the repellent effect against black rats was tested under the same conditions.

The space (height 10 cm) under the same wide double floor material as in the test of "survival ratio of ambient concentration by spraying" is shown in FIG.
As shown in Fig. 4, it is divided into 10 × 10 (m) compartments, further divided in half with a filling material, an opening (width 10 cm) 10 is provided at the end, and sufficient food 11 and water 12 are placed as shown in FIG.
Furthermore, the infrared video camera 13 is set under the floor and the black rat R. Five rattus were released, acclimated for one week, and their movements were observed. The black rat confirmed that he would live in 50% of both rooms without bias. Then, rodent-proof and insect-control aerosols were sprayed from the notch (85 mm square) 14 of one room shown in FIG. As a result, it was on the 9th day after the injection that the first black rat appeared in the room.
