However, although the drug volatilizer described in Patent Document 1 has openings on the front, back, and side surfaces, the drug container has a very thin thickness of about 1 cm. The flow of air passing through the inside of the medicine container between the opening and the opening is less than the flow of air between the opening on the front and the opening on the back.
About this point, since the chemical volatilization body of patent document 1 is equipped with the hook part 6 which can be locked and used for a door knob as shown in FIG. It will appear remarkably when locked and used. That is, when the hook portion 6 is used while being locked to the door knob, the back surface of the medicine container contacts the door surface or is used with almost no gap between the door surface. A sex medicine will volatilize from the inside of a medicine container mainly by the flow of the air which passes between the opening of a side, and the opening of a front and back, and volatilization efficiency will fall.

  The present invention has been made in view of the above-described conventional problems, and even when used by being locked to a door knob, the door knob agent can ensure sufficient volatilization efficiency of the room temperature volatile agent. The purpose is to provide a volatilization body.

  In order to achieve the above-mentioned object, a door knob drug volatilizer according to claim 1 of the present invention is a door knob drug volatilizer containing a carrier holding a room temperature volatile drug in a drug container having an opening. The opening is provided at least on the side and front, the area of the opening (A) on the side is 10 to 50% of the entire area of the side, and the total area of the opening (B) on the front and back Is 10 to 50% of the total area of the front surface and the back surface, and the area ratio between the opening portion (A) provided on the side surface and the opening portion (B) provided on the front surface and the back surface is A / B = 0. .3 to 3.0.

  The drug volatilizer for a doorknob according to claim 2 of the present invention is such that the drug container has a rectangular parallelepiped main body portion and a cross-sectional shape in a side view of any of a triangular shape, a convex shape, a trapezoidal shape, an arc shape, and a curved shape It is characterized by comprising a lid having a shape.

  According to a third aspect of the present invention, there is provided a door knob drug volatilizer comprising a drug container provided with a foot.

  The door knob drug volatilizer according to claim 4 of the present invention is characterized in that the room-temperature volatile drug uses at least one drug selected from transfluthrin, metfurthrin, empentrin, and profluthrin.

(Drug container)
The drug container used in the present invention is not particularly limited in form as long as it can store a carrier holding a room-temperature volatile drug, which will be described later, but in order to facilitate the exchange of the carrier, It is preferable that the carrier is accommodated by the portion.

The shape of the drug container is not particularly limited as long as it can volatilize the room-temperature volatile drug from the opening of the stored carrier, but it is room temperature volatile by placing it on the air flow formed by the opening described later. In order to volatilize the drug effectively, it is preferable to make the thickness of the center of the drug container thicker than the end. Specifically, the thickness of the center of the drug container is preferably 0.5 to 5.0 cm thicker than the end portion. For example, as shown in FIG. 1, the drug container has a rectangular parallelepiped body portion and a side view. The form formed by the cover part in which the cross-sectional shape in this is circular arc shape is mentioned. The drug container 4 shown in FIG. 1 has a bowl-like shape with a thickness of about 3.6 cm at the center and a thickness of about 1.8 cm at the end.
In addition to the arc shape, the lid portion may have a cross-sectional shape that is any one of a triangular shape, a convex shape, a trapezoidal shape, an arc shape, and a curved shape in a side view.

  Further, the drug container used in the present invention can be provided with a hook portion so that the drug container can be hooked on the door knob and hung. Such a hook portion can be provided with an adjustment function that can adjust the size of the hook portion in accordance with the size of the door knob, like the adjustment hole and opening 9 shown in FIG.

(Aperture)
It is necessary to provide openings on the side and front of the drug container of the present invention in order to volatilize the room temperature volatile drug out of the drug container.
Note that whether or not to provide an opening on the back surface of the drug container is appropriately determined as necessary. Specifically, the drug container used in the present invention can be provided with a foot portion for erecting the container. However, by providing the foot portion on the back surface of the drug container, the back surface of the drug container and the door are provided. When a gap can be ensured between the surface and the surface, it is preferable to provide an opening on the back surface of the drug container.

  On the other hand, since the chemical volatilization body of the present invention is mainly used by hooking and hanging the hook part on the door knob, when the foot part is not on the back side of the chemical container, the back side of the chemical container is the door. It will be in the state which contacts a surface or there is almost no clearance gap between door surfaces. Therefore, in such a state, that is, when it is not particularly necessary to secure the air flow between the opening on the back surface and the opening on the side surface and the front surface, do not provide the opening on the back surface of the medicine container. It can also be.

  Here, the area occupied by the opening on each surface (opening ratio) is preferably 10 to 50% of the entire area of the side surface for the opening on the side surface from the viewpoint of volatilization efficiency. Is preferably 10 to 50% of the entire area of the front and back surfaces.

  Furthermore, also about the area ratio (opening ratio) of the opening part (A) provided in the side surface and the opening part (B) provided in the front surface and the back surface, A / B = 0.3-3 from the point of volatilization efficiency. 0.0 is preferable.

(Room temperature volatile chemicals)
The room temperature volatile drug used in the present invention is not particularly limited as long as it has a property of volatilizing in the air at room temperature, but a pyrethroid type drug is used in order to exert a stronger insect-proof effect. Among these, from the viewpoint of volatilization performance, it is preferable to use transfluthrin, metfurthrin, empentrin, or profluthrin.
As for these pyrethroid drugs, there are various optical isomers or geometric isomers, but any isomers can be used, and more than two kinds can be used in combination. it can.

In addition, a synergist, a repellent, an antibacterial agent, an antifungal agent, a fragrance, a fragrance, etc. can be used simultaneously for the room temperature volatile chemical | medical agent used by this invention.
For example, as a synergist, octachlorodipropyl ether (trade name S-421), isobornyl thiocyanoacetate (trade name IBTA), N-octylbicycloheptenecarboximide (trade name Sinepilin 222), N- (2-ethylhexyl) -1-isopropyl-4-methylbicyclo [2,2,2] oct-5-ene-2,3-dicarboximide (trade name Sinepirine 500).
As repellents, N, N-diethyl-m-toluamide (trade name Diet), dimethyl phthalate, dibutyl phthalate, 2-ethyl-1,3-hexanediol, 1,4,4a, 5a, 6,9, Examples include 9a, 9b-octahydrodibenzofuran-4a-carbaldehyde, p-menthane-3,8-diol, and the like.
Antibacterial agents include hinokitiol, tetrahydrolinalol, eugenol, citronellal, allyl isothiocyanate, and the like.
Examples of the antifungal agent include isopropylmethylphenol and orthophenylphenol.
As a fragrance, citronella oil, orange oil, lemon oil, lime oil, yuzu oil, lavender oil, peppermint oil, eucalyptus oil, jasmine oil, coconut oil, green tea essential oil, limonene, α-pinene, linalool, geraniol, phenylethyl Examples include alcohol, amylcinnamic aldehyde, cuminaldehyde, and benzyl acetate.
Examples of the fragrances include fragrance ingredients containing green leaf alcohol and green leaf aldehyde called “green fragrance”.
Furthermore, a coloring agent, an antistatic agent, etc. may be mix | blended suitably, and if a color is added or a time indicator is equipped so that the end point of use can be visually recognized, the commercial value can be further increased.

  In addition, the room temperature volatile chemicals used in the present invention have sufficient stability, but in order to further improve the stability, it is possible to add a stabilizer such as an antioxidant, for example, 2,2'-methylenebis (4-ethyl-6-t-butylphenol), 4,4'-methylenebis (2-methyl-6-t-butylphenol), BHT, BHA, mercaptobenzimidazole and the like can be used.

  Further, by using ultraviolet absorbers such as paraaminobenzoic acids, cinnamic acids, salicylic acids, benzophenones and benzotriazoles as ultraviolet absorption inhibitors, the light resistance during storage and use can be further improved.

(Carrier)
The carrier used in the present invention is not particularly limited as long as it can gradually volatilize the retained room temperature volatile agent from the surface, for example, a polyolefin resin such as a polyethylene resin or a polypropylene resin, Alternatively, resin carriers formed by polymerizing monomers such as carboxylic acid esters, paper carriers such as pulp paper, paperboard, and synthetic fiber mixed paper, and fiber carriers such as nonwoven fabrics and woven fabrics. Can be mentioned.
By having such a structure, the volatilization rate of each room temperature volatile chemical | medical agent can be made according to each room temperature volatile chemical | medical agent, and a more effective insect-proof effect can be expressed.
In addition, these carriers may be used alone as in the case of the room temperature volatile chemicals, or two or more of them may be used in combination.

  In addition, in the resin carrier, a polymer blend in which the content ratio of the polyolefin copolymer containing a large amount of the carboxylic acid ester monomer and the olefin homopolymer is adjusted and mixed can be used. Depending on the case, other high molecular compounds such as styrene-based thermal elastomer may be contained.

The monomer such as carboxylic acid ester is effective for controlling the volatilization of the room temperature volatile chemical from the carrier surface. For example, methyl acrylate, ethyl acrylate, methyl methacrylate, methacryl Examples include ethyl acid and vinyl acetate.
Furthermore, the blending ratio of these carboxylic acid ester monomers with respect to the polyolefin resin is generally used because the higher the carboxylic acid ester monomer blending ratio tends to slow the bleed speed of the room temperature volatile chemical. What is necessary is just to adjust suitably according to the kind and content of a room temperature volatile chemical | medical agent, or a use purpose, Preferably it adjusts in 1-20 mass% with respect to polyolefin resin.

  The method for retaining the room temperature volatile drug on the carrier in the present invention is not particularly limited as long as it is a method capable of gradually vaporizing the room temperature volatile drug held on the carrier from the surface of the carrier. Examples thereof include a method in which a room temperature volatile chemical is kneaded into a carrier and is held, and a method in which a room temperature volatile chemical is impregnated or kneaded in a paper or fiber carrier.

Here, when a resin carrier is used as the carrier, it is preferably meshed from the viewpoint of volatilization efficiency, and the diameter of the filament of the mesh is also in the range of 0.1 to 2 mm from the point of volatilization efficiency. It is preferable to make it.
In addition, the diameter of a filament is suitably set from the said range according to the kind and usage period of a normal temperature volatile chemical | medical agent. That is, in the case of a room-temperature volatile chemical with a high vapor pressure (high volatilization rate), it is adjusted to suppress volatilization by increasing the filament diameter, and the vapor pressure is low (low volatilization rate) In the case of a drug, adjustment is made to promote volatilization by reducing the filament diameter.

  Moreover, it is preferable to make it the range of 40-85% also from the point of volatilization efficiency and air permeability also about the magnitude | size (opening rate) of the mesh (opening) of a mesh, and also to make it 50-75%. preferable.

  On the other hand, the mesh shape of the mesh is not particularly limited, and may be appropriately set such as a square shape, a rhombus shape, and a hexagon shape as necessary.

The content of the room temperature volatile drug retained on the carrier will be appropriately determined depending on the type of room temperature volatile drug used, the usage environment, the conditions of use, etc. In order to facilitate molding after kneading a room temperature volatile chemical when using a resin carrier, and to prevent the room temperature volatile chemical from excessively bleeding on the surface of the carrier and causing stickiness, 0 It is preferable to be in the range of 5 to 15% by weight.
That is, when the content of the room temperature volatile drug is less than 0.5% by weight, it is difficult to secure the amount of the active ingredient necessary for insect control, while the content of the room temperature volatile drug is 15% by weight. In the case of exceeding the above, when a resin carrier is used, molding after kneading the room temperature volatile chemical becomes difficult, and the room temperature volatile chemical excessively bleeds on the surface of the carrier and is likely to cause stickiness. .

In addition, normally, content of the normal temperature volatile chemical | medical agent mix | blended with a support | carrier is about 30-600 mg, and is illustrated as the usage-amount about about 30-120 days.
Moreover, in setting the content, although it varies depending on the type of the room temperature volatile chemical to be used, for example, when using metfurthrin alone, the minimum volatilization amount necessary for exhibiting the insect-proofing effect is 0.03 mg / Since it is 0.03 mg / hr or more for profluthrin alone and 0.06 mg / hr or more for transfluthrin alone, the content at 30 days is 30 to 500 mg for metofluthrin and 30 to 30 for proflothrin. In the case of 300 mg and transfluthrin, it may be set in the range of 60 to 500 mg.
