Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention is a disposable miticidal disposable product in which a disposable dust bag installed in an electric vacuum cleaner contains a unit amount of a granular preparation containing menthone. The present invention relates to a dust collecting bag.

(B) Conventional techniques and problems to be solved Recently, it has been regarded as a problem that mites are involved in the cause of asthma in the home, and as a countermeasure, mite species are removed by sucking futons and carpet with an electric vacuum cleaner. This is one effective means. However, among the inhaled mites, it is said that the mite, Plutella xylostella, is almost killed by mechanical action, but it has been found that the mosquitoes, Dermatophagoides farinae and Dermatophagoides farinae, which cause asthma, are hard to die by mechanical action. ing. Therefore, even if the dust mites are stored in the electric vacuum cleaner once, they are extremely small pests, and it is possible that some of them will come out of the vacuum cleaner again.

As a countermeasure against this, in an electric vacuum cleaner of a type that collects dust in a paper bag, a paper bag and a support for fixing the paper bag to the vacuum cleaner have been proposed in which a microbial insecticide is permeated or applied ( (See JP-A-59-207124).

However, the above-mentioned publication does not specifically disclose what the microbial insecticide is composed of, nor does it specifically show how the insecticide is impregnated or applied.

On the other hand, conventionally used acaricides are diversions of publicly known pesticides, which are usually highly toxic and have an effect upon contact with mites, but they have not always been sufficient.

Then, as a result of studying various drugs, the inventor found that 1-mentone showed an insecticidal effect against dust mites by its vapor. However, since l-menthone is a liquid and can be used as an object by permeation, it has a problem of durability.

(C) Means and Actions for Solving the Problems Thus, according to the present invention, the disposable dust-collecting bag body installed in the electric vacuum cleaner contains a unit amount of the menthone-containing granular preparation for acaricide. Provided is a disposable dust-collecting bag.

The menthone-containing granular preparation used in this invention is 1-
(Mentone and 1-menthone-containing essential oil) impregnated and retained in a porous inorganic particle) encapsulated in an inclusion compound such as cyclodextrin) microencapsulated with a polymer film) laccamide (Dainippon Ink and Chemicals) Resins such as industrial polyamide resins) are included.

The l-menthone used in this invention is usually about 30% in essential oils such as mint oil (including those obtained from mint (Mentha arvensis L. var.piperascens Holmes) and mint (Mentha Piperita L.)) and peniroyal oil. %
It is contained and is the most naturally occurring isomer among the four optically active forms of menthone, and is a volatile liquid (bp 209 to 210 ° C) at room temperature.

As the active ingredient of the preparation of the present invention, 1-menthone may be substantially contained. Substantially containing means at least about 10% (by weight), preferably about 25% or more,
More preferably, it means containing at least 32%. Therefore, in addition to l-menthone, other isomers of menthone may be contained, and dementhmented oil obtained by dementing mint oil [also known as menton oil (l-menton content about 70%) or mentha white oil (l -Mentone content about 30%] and the like.

It is not known that such l-menthone actually has an acaricidal effect, and according to the study by the present inventors, 1-mentone exerts an insecticidal effect by contact with dust mites, which have a low effect with ordinary insecticides. It has been found that it is a very unique drug that not only shows but also shows an insecticidal effect by its vapor. 1-Mentone exerts an insecticidal effect when it is further brought into contact with the mites, Plutella xylostella, and Acarina. In addition, l-
Menthone is virtually non-toxic and harmless to the human body.
However, since l-menthone is an oil and a volatile oil, it is not suitable for direct use in a bag for dust collection, and it has been found that it is suitable to use it as a sustained release containing preparation.

As the l-menthone-containing granular preparation, those obtained by impregnating and holding the porous inorganic granular material are preferable from the viewpoints of economy and handling. Examples of porous inorganic particles include silica, calcium silicate, alumina gel, and shirasu.
The size of these granules is about 0.5 to 5 mm in diameter. Further, the granular material may be molded into a disc shape for use. In this case, the size may be, for example, about 20 mm in diameter, but is not limited to this. Impregnation of the granular material with 1-menthone or an essential oil containing the same can be performed by either a direct spraying method or an impregnation method. In this case, l-menthone is replaced with dipropylene glycol (DPG),
It is preferred to dilute and impregnate a retaining agent such as polyethylene glycol (PEG) or liquid paraffin. More specifically, for example, Fluorite RM-30 (made by Tokuyama Soto) 1 kg
Examples of the method include spraying a blend of 1 kg of l-menthone and 1 kg of DPG directly and uniformly.

The unit usage amount of the menthone-containing granular preparation in the present invention means an amount used once for one dust bag. The amount used varies depending on the size of the dust bag and the period of use. The dust bag is usually abandoned within 1-2 months, and during that period, an effective amount of 1 against dust mites
-It is preferred to use an amount sufficient to supply menthone vapor. The specific amount is appropriately determined with reference to the properties of 1-menthone and the material of the sustained-release preparation, such as porosity, pore size, preparation size, and unit surface area.

The unit amount of the menthone-containing granular preparation may be put in the dust bag in advance, but it should be taken out in a sealed container such as a polymer film, aluminum laminated film or paper when it is put in, and the dust bag should be taken out. It is preferable to use the method of putting it in the body of the body.

In addition, the dust-collecting bag usually has a support body having a dust suction port at a substantially central portion for attaching to a vacuum cleaner and 2
It consists of a bag of the main body consisting of three to three layers,
The menthone-containing granular preparation may be adhered to an appropriate portion of the above-mentioned support (for example, a portion located inside the bag of the main body), or may be previously inserted between two or three layers of the main body bag. . Still another application is an O-ring shape having an inner diameter larger than the diameter of the dust collecting port of the dust collecting bag, such as a mesh pipe that can hold the above-mentioned granular preparation and is breathable and flexible. Examples of such a method include forming an object and holding the granular preparation in the O-ring-shaped object, adhering it to the inside of the bag body so as to be located around the dust suction port, or locking it to the mouth.

The disposable dust-collecting bag installed in the electric vacuum cleaner according to the present invention is a known bag itself, and the shape and material thereof are not particularly limited.

(D) Example FIG. 1 shows one specific example of the acaricidal disposable dust collecting bag of the present invention.

1 is a main body of a paper bag body, 2 is a support for attaching to a vacuum cleaner, and 3 is a menthone-containing granular preparation. Granules containing menthone are porous silica with an average diameter of 3 mm1
20 g of a mixed solution obtained by blending 0 g of mint oil (containing 30% of 1-menthone) 10 g of dipropylene glycol (DPG),
It was made by direct spraying and impregnation, and 1.5 g of this preparation contains 0.15 g of 1-menthon as a unit dose.
Then, this preparation is stored in a non-breathable polymer film, opened at the body of the bag at the time of use, and the granular preparation is inserted.

(E) Effect of the device In the bag for dust collection according to the device, mites housed together with dust are killed therein, and mites do not go out. The acaricide used is gradually evaporated and released from the granular preparation in the bag body and exhibits an acaricidal effect for a relatively long period of time, and since it is harmless to the human body, there is no problem in handling at home.
