Description

  The present invention relates to a spray container and a container-containing insecticide.

In general, an insecticide contained in a container in which an aerosol-type spray container is filled with an insecticide is known. This container-containing insecticide injects an insecticide toward sanitary pests such as cockroaches, flies, and mosquitoes by pressing an injection button in which an injection hole is formed.
In order to control sanitary pests, particularly cockroaches, users of container-containing pesticides are required to spray insecticides from as far as possible to reliably control cockroaches.

In response to these demands, the number of insecticides to be sprayed at one time, the use of highly effective insecticides, and the extension of the spraying distance of insecticides have been devised. There was a problem that the sprayed insecticide was difficult to hit the cockroach because it was quick. In addition, cockroaches often hide in narrow spaces such as dark spaces and furniture gaps, and there is a problem that it is difficult to determine the spraying direction of the insecticide by visual inspection. Furthermore, if the insecticide is sprayed while holding the insecticide in a container with one hand and operating a lighting device such as a flashlight with the other hand, the spraying direction of the insecticide and the irradiation direction of the lighting device do not necessarily match. There was a problem that the insecticide could not be accurately sprayed on the cockroach.
In order to solve such a problem, a spray-type insecticide provided with an aiming device has been proposed (for example, Patent Document 1).

Japanese Utility Model Publication 2-91664

However, the technique of Patent Document 1 is for spraying an insecticide while looking into the sight, and the user presses the spray button with the face close to the spray-type insecticide, so that the operation is complicated. . In addition, even though the user wants to be as far away from the removal target as possible, the user can look into the sight to bring the face closer to the removal target. Furthermore, it is difficult to visually confirm the extermination object lurking in a dark place or a narrow part.
Therefore, an object of the present invention is to provide a spray container and a container-containing insecticide capable of accurately spraying contents even in a dark place or a narrow part.

  An injection container according to the present invention includes a container main body for storing the contents, an injection means that is attached to the container main body and injects the contents, and a light irradiation means that irradiates light in substantially the same direction as the injection direction of the contents It is characterized by providing. The light irradiation means preferably uses an LED as a light source.

  The container-containing insecticide of the present invention is characterized in that the spray container of the present invention is filled with an insecticide. It is preferable that the light irradiation means irradiates light having a wavelength of 500 to 750 nm.

According to the spray container of the present invention, the spray container includes the spray unit that is mounted on the container body and sprays the contents, and the light irradiation unit that irradiates light in the substantially same direction as the spray direction of the contents. According to the injection container of the present invention, the light source of the light irradiating means is an LED, so that the size can be reduced.

According to the insecticide contained in the container of the present invention, since the spray container of the present invention is filled with the insecticide, the contents can be accurately ejected to the extermination object even in a dark place or a narrow part.
According to the insecticide contained in a container of the present invention, since the light irradiation means irradiates light with a wavelength of 500 to 750 nm, the contents can be easily sprayed on the target to be removed.

It is a perspective view of the injection container concerning one embodiment of the present invention. It is a fragmentary sectional view of the injection container concerning one embodiment of the present invention. It is a fragmentary sectional view of the injection container concerning one embodiment of the present invention. It is a fragmentary sectional view of the injection container concerning one embodiment of the present invention.

  The injection container concerning one Embodiment of this invention is demonstrated with reference to FIGS. 1-2 below. As shown in FIG. 1, the injection container 1 includes a container body 3 including a bottomed cylindrical body 34 and a mouth part 32 having a reduced diameter on the upper part of the body part 34, and an injection unit 2 attached to the mouth 32. For example, liquid contents such as an insecticide, a cleaning agent, and a lubricant are ejected. For convenience of explanation, the injection unit 2 side will be described as the upper side, and the container body 3 side will be described as the lower side.

The injection unit 2 includes a fitting portion 23 that fits into the mouth portion 32, an operation portion 10, and an injection nozzle 22 in which an injection hole 21 is formed. Two support plates 24 are erected above the fitting portion 23, and the operation portion 10 is pivotally supported on the support plate 24 by a support shaft 26.
As shown in FIG. 2, the injection nozzle 22 is connected to an injection button 38 provided in the mouth 32, and injects the contents in the container body 3 in the injection direction F when the injection button 38 is pressed. It is. An irradiation switch 36 is provided above the injection button 38, and the operation unit 10 and the injection button 38 are connected via the irradiation switch 36.

  The operation unit 10 includes an irradiating unit 11 and a lever 20 extending below the irradiating unit 11, and is rotatable about the support shaft 26 when the lever 20 is operated. It is. An irradiation hole 12 that is a substantially circular opening and a light guide path 13 that follows the irradiation hole 12 are formed in the irradiation section 11. , And a light source 15 located on the opposite side of the irradiation hole 12 with the condenser lens 14 interposed therebetween. The light source 15 is electrically connected to the battery 16 and the irradiation switch 36.

In the present embodiment, the “injection means” includes the injection nozzle 22 and the injection button 38.
In the present embodiment, the “light irradiating means” includes an irradiation hole 12, a light guide path 13, a condenser lens 14, and a light source 15, and an irradiation direction S of light irradiated from the irradiation hole 12 is set. The direction is substantially the same as the injection direction F. Here, “substantially the same direction” means that the center of the spread (irradiation range) of the light irradiated from the irradiation unit 11 at the distance (effective injection distance) at which the contents can be effectively injected onto the injection target is the injection nozzle 22. It means entering into the spread (injection range) of the contents when the contents are ejected from. For example, when the content is an insecticide, the distance between the tip of the spray nozzle 22 and the removal target is usually 50 to 100 cm. For this reason, it is preferable that the irradiation direction S and the injection direction F are set such that the center of the irradiation range is located within the injection range at a distance of 50 to 100 cm from the tip of the injection nozzle 22.
The effective spray distance can be determined according to the application. For example, when the content is an insecticide, the effective spray distance is, for example, a distance of 20 to 120 cm from the tip of the spray nozzle 22. The effective spray distance can be set to an arbitrary distance by adjusting the length of the spray nozzle 22 and the ratio of the propellant in the content liquid.
The injection range is arbitrarily set depending on the hole diameter and shape of the injection hole 21 and the ratio of the propellant in the content liquid.
The irradiation range is arbitrarily set by changing the type of the light source 15 and the type of the condenser lens 14.

 The container body 3 may be anything that has been conventionally used as an aerosol container, and examples thereof include a pressure-resistant container made of metal such as tinplate, resin, or glass.

 The hole diameter R (FIG. 2) of the irradiation hole 12 is not specifically limited, For example, you may be 2-15 mm.

The light source 15 is not specifically limited, For example, LED (light emitting diode), a halogen lamp, an incandescent lamp etc. are mentioned, Among these, LED is preferable. If it is LED, the irradiation part 11 can be reduced in size. In addition, it is possible to irradiate light of a specific wavelength. For example, in the case where the content is an insecticide, by eliminating light in the ultraviolet region, it is possible to prevent repelling behavior against ultraviolet light to be removed.
The light emitted from the light source 15 can be determined according to the application. For example, when the contents are used as an insecticide, the light can be determined in consideration of the repellent property of sanitary pests to be controlled. For example, when the target for extermination is a cockroach, white light, red light, orange light, yellow light, and green light are preferable, among which green to yellow to red that are 500 to 750 nm are more preferable, and 560 to 700 nm are more preferable. By using a light source having such a wavelength, the repelling behavior of cockroaches when irradiated with light can be prevented, and the contents can be ejected onto the cockroaches.

  The condensing lens 14 should just be what can condense the light which the light source 15 emits to arbitrary ranges. Usually, within the effective injection distance, the injected content has a high concentration at the center of the injection range. For this reason, when the irradiation range is too wide, it becomes difficult to apply the center of the spray range to the injection target. On the other hand, if the irradiation range is too narrow, it is difficult to aim at the injection target in a dark place or a narrow part. Accordingly, the irradiation range can be determined in consideration of the application, effective injection distance, injection range, and the like. Is preferable, and 5 to 20 cm is more preferable.

The contents stored in the container body 3 contain insecticides, repellents, cleaning agents, bactericides, lubricants and the like and propellants, and among them, those containing insecticides and propellants are preferable. . The effect of the present invention is remarkable in the control of sanitary pests lurking in a dark place or a narrow part.

These can be used individually by 1 type or in combination of 2 or more types.

 The repellent contains an active ingredient having a repellent action against pests, and as an active ingredient, DEET, IR-3535, methylundecyl ketone, nerolidol, pinene, eucalyptol, citronellal, camphor, linalool, Geraniol, p-menthane-3,8-diol, terpineol, 2-ethyl-1,3-hexanediol, repellents such as cinnamic aldehyde, eugenol, pyrethroid, eucalyptus, cinnamon, citronella, clove, laurel, pine, peppermint , Essential oils extracted from geranium, hiba, lemongrass, etc., extracts and the like. These can be used individually by 1 type or in combination of 2 or more types.

The solvent used for the insecticide or repellent is not particularly limited. For example, water, alcohols such as methanol, ethanol and 2-propanol, glycols such as ethylene glycol and propylene glycol, ethylene glycol monomethyl ether and ethylene glycol mono Alkylene glycol alkyl ethers such as ethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, propylene glycol monoethyl ether, dipropylene glycol monomethyl ether, hexylene glycol, methyl stearate, ethyl stearate, diisopropyl adipate , Diisobutyl adipate, methyl lactate, ethyl lactate, butyl lactate, iso myristate Fatty acids such as organic acid esters such as propyl, n-butyl myristate, isobutyl myristate, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclic esters such as propylene carbonate, hexane, pentane, isopentane, cyclopentane, kerosene Group hydrocarbons, dimethyl carbonate, diethyl carbonate, N-methyl-2-pyrrolidone, N-ethyl-2-pyrrolidone, γ-butyrolactone and the like.

Next, the usage method of the injection container 1 is demonstrated using FIGS.
The injection container 1 in FIG. 2 is in a state where the lever 20 is not operated and the irradiation switch 36 and the injection button 38 are not pressed. Hereinafter, the state of FIG. 2 is referred to as “normal state”. FIG. 3 is a partial cross-sectional view of the injection device 1 showing a state in which light is irradiated toward the injection target. FIG. 4 is an injection showing a state in which the contents are injected while irradiating the light toward the injection target. 2 is a partial cross-sectional view of the device 1.
A finger is put on the lever 20 of the normal injection container 1, the injection nozzle 22 is directed toward the injection target, and the lever 20 is operated in the direction of arrow A, that is, the direction approaching the container body 3. When the lever 20 is operated in the direction of arrow A, the operation unit 10 rotates about the support shaft 26 to enter the operation unit 10a (FIG. 3), and the irradiation switch 36 is pressed to turn on the light source 15. The light emitted from the lit light source 15 propagates in the light guide path 13, passes through the condenser lens 14, and is irradiated from the irradiation hole 12 as the irradiation light 17 in the irradiation direction S. At this time, since the injection button 38 is not pressed, the contents are not injected (the aiming operation is described above).

  Next, while irradiating the irradiation light 17 to the injection target, the lever 20 is further operated in the direction of arrow B (FIG. 3), and the operation unit 10a is rotated about the support shaft 26 as the axis of the operation unit 10b. State (FIG. 4). The operation unit 10 b presses the injection button 38 via the irradiation switch 36 and injects the content liquid in the container main body 3 from the injection hole 21 in the injection direction F. Then, the content liquid becomes a spray liquid 27 that spreads in a mist shape in an arbitrary shape, and is sprayed onto a spray target (a spray operation). At this time, the irradiation direction S1 shown in FIG. 4 is inclined downward as compared with the irradiation direction S shown in FIG. 3. However, since the injection target is caught within the injection range by the aiming operation, Injected into an injection range corresponding to the irradiation range determined by the aiming operation.

According to this embodiment, since the light irradiation means for irradiating light in substantially the same direction as the content injection direction is provided, the content can be accurately injected onto the injection target even in a dark place or a narrow portion. In addition, the injection direction can be matched with the injection target even if it is away from the injection target.
Furthermore, since the aiming operation and the injection operation can be performed by a series of operations of one lever, the contents can be injected onto the injection target more easily and accurately.

The present invention is not limited to the above-described embodiment.
In the above-described embodiment, an aerosol-type container is used, but the present invention is not limited to this. For example, a container including a trigger pump, that is, a pump is operated by operating a lever, and a certain amount of contents are stored. You may inject. In addition, when using the container provided with a trigger pump, the content does not need to contain a propellant.

 In the above-described embodiment, the aiming operation and the ejection operation can be performed by one lever. However, the present invention is not limited to this, and the aiming operation and the ejection operation can be performed using different levers, switches, buttons, or the like. You may perform by operation. For example, the light source is turned on by pressing a switch provided in the operation unit, and the contents are operated by operating the lever while pressing this switch. However, in order to inject the contents to the injection target more easily and accurately, it is preferable that the aiming operation and the injection operation can be performed by a series of operations of one lever as in the above-described embodiment.

 In the above-described embodiment, the irradiation unit and the lever are integrated, but the present invention is not limited to this, and the irradiation unit and the lever may be separated.

 In the above-described embodiment, the irradiation unit is provided on the upper portion of the lever. However, the present invention is not limited to this, and for example, the irradiation unit may be provided on the container body or on the support plate of the operation unit. It may be provided. Moreover, an irradiation part, a lever, and an injection hole may be integrated. However, from the viewpoint of preventing an obstacle when gripping the container body or an obstacle when operating the lever, it is preferable that the irradiating portion is provided on the upper portion of the lever.

  EXAMPLES Hereinafter, although an Example is shown and this invention is demonstrated in detail, this invention is not limited by the following description.

(Example 1)
An LED (product name: OSHR5161A-QR, color tone: red, dominant wavelength (λd); 620 to 630 nm, standard luminous intensity: 7 cd, manufactured by Opto Supply Limited) is used as a light source, and an injection container similar to the injection container 1 of FIG. Produced.
A bottomed cylindrical container with a diameter of 42 cm was placed under twilight, and one cockroach was released into the container and allowed to acclimatize by leaving it for more than 30 minutes. Thereafter, when the cockroach was stationary, the cockroach was irradiated with light from the injection container (irradiation range: φ10 cm, LED energization condition: 24.5 mA), and the time until the cockroach repellent behavior was observed was measured. The repellent behavior was observed for three males and three females for the three species of American cockroaches, German cockroaches and black cockroaches. The time until repellent behavior was observed (the time required to exit from the irradiation range of φ10 cm) was scored according to the following repellent judgment criteria, and the average value for each type of cockroach was defined as repellent by type. The average values of the three types of cockroach repellency were classified into the following comprehensive judgment criteria, and were evaluated as comprehensive evaluations. These results are shown in Table 1.

5 points: No repellent behavior is seen even after 60 seconds.
4 points: Time to repelling behavior was 30 seconds or more and less than 60 seconds.
3 points: Time to repelling action was 15 seconds or more and less than 30 seconds.
2 points: Time to repelling behavior was 5 seconds or more and less than 15 seconds.
1 point: Time to repelling behavior was less than 5 seconds.

<Comprehensive evaluation criteria>
A: The average repellency by type (repellency average) is 4.7 points or more (no repellency behavior is observed).
A: Average repellent property is 4.0 points or more and less than 4.7 points (almost no repellent behavior is observed).
A: The average repellency is 3.0 points or more and less than 4.0 points (repellency behavior is slightly recognized).
