  The present invention provides a control device that contains a liquid for controlling dwarf sanitary pests. The control device of the present invention is intended for sanitary pests having the property of walking around the ground (that is, dwarf) (hereinafter referred to as dwarf sanitary pests) and is intended to control them.

  Embodiments of the present invention will be described below. FIG. 1 is a perspective view of a pest control apparatus 10 according to an embodiment of the present invention, and FIGS. 2 to 4 are cross-sectional views of the pest control apparatus 10 according to an embodiment of the present invention.

  The pest control apparatus 10 of this embodiment includes a bottle part 1 and a liquid absorbing part 2 for sucking the liquid from the inside of the bottle part 1 to the outside when the liquid is accommodated in the bottle part 1. . The bottle portion 1 includes a bottom portion 1b that faces the floor surface when the pest control device 10 is placed on the floor surface, and an upper surface portion 1a that is not intended to face the floor surface. A first opening 3 is provided in 1a. The liquid absorption part 2 has a configuration in which the first opening 3 is sealed and the inside of the bottle part 1 is communicated with the outside through the first opening 3. Specifically, the liquid absorption part 2 is provided with a sheath 2a and a liquid absorption core 2b that fits through the lumen of the sheath 2a, and the liquid absorption core 2b extends in the internal direction and the external direction of the bottle part 1. It has an end face (also referred to as an inner end and an outer end, respectively) and a side face in close contact with the lumen of the sheath 2a, and a first opening is formed at the end of the sheath 2a near the outer end of the liquid absorbent core 2b. A plug portion 2c that is in close contact with the portion 3 is configured.

  In the figure, a second opening 4 is provided in the upper surface portion 1a of the bottle portion 1, and a breathable liquid sealing portion 5 for sealing the liquid 6 inside the bottle portion 1 is second. The opening 4 is covered.

  Since the breathable liquid sealing part 5 covers the 2nd opening part 4, the liquid accommodated in the inside of the bottle part 1 is the pest control instrument 10 of this embodiment, even if the bottle part 1 falls down. There is no leakage from the second opening 4. Furthermore, even if the container is heated as the room temperature rises, the air inside the expanded bottle part 1 is expelled from the second opening 4 to the outside of the bottle part 1, so that the inside of the bottle part 1 This liquid does not leak out of the bottle part 1 through the liquid absorption core 2b.

  The liquid is accommodated in the bottle part 1, the liquid absorbing part 2 is inserted from the outside of the bottle part 1 to the inside through the first opening 3, and the stopper part 2 c is in close contact with the first opening 3. As a result, the inner end of the liquid absorbent core 2 b comes into contact with the liquid, and the outer end of the liquid absorbent core 2 b faces the outside of the bottle part 1. Since the first opening 3 is sealed by the liquid absorption part 2 and the lumen of the sheath 2a is in intimate contact with the liquid absorption core 2b, the liquid absorption core is provided between the inside and the outside of the bottle part 1. 2b and the second opening 4 communicate with each other. The liquid inside the bottle 1 is sucked out of the bottle 1 through the liquid absorbent core 2b, and the gas inside and outside the bottle 1 is opened at the second opening. The inside and outside of the bottle part 1 can be moved via the part 4.

  As described above, the pest control device 10 of the present embodiment allows the duck hygiene pest approaching the upper surface portion 1a of the bottle portion 1 to absorb the liquid sucked up to the end surface of the liquid absorbing core 2b of the liquid absorbing portion 2 to the outer end. It is an instrument for controlling dwarf hygiene pests that are killed by licking.

  The pest control device 10 of the present embodiment is a device that can be used without causing liquid to leak from the bottle portion 1. The shape of the bottle part 1 is not limited to the semicircular shape shown in the drawing, as long as the pest can reach the outer end of the liquid absorbent core 2b. It may be designed in consideration of the amount of liquid to be stored in the bottle part 1 and the user's preference regarding the appearance, and may be a cylindrical shape, a prismatic shape (cube or rectangular parallelepiped), or a cone or pyramid shape Good.

  The 2nd opening part 4 should just be provided in area | regions other than a bottom face part, and is not limited to the upper surface part 1a of the bottle part 1. FIG. That is, the 2nd opening part 4 may be provided in the stopper part 2c. A configuration in which the second opening 4 is provided in the plug 2c is shown in FIGS. 2b and 3b.

  The pest control device 10 of the present embodiment does not need to consider the pressure resistance of the bottle portion 1 because the second opening 4 is provided. The material of the bottle part 1 is not particularly limited as long as it does not affect the liquid to be stored. For example, polyester resin (for example, polyethylene terephthalate (PET)), olefin resin (for example, polypropylene (PP), polyethylene (PE)) Etc.), glass, ceramics and the like are preferably used. Moreover, in order to visually observe the amount of liquid remaining inside, the bottle part 1 may be transparent.

  The material of the sheath 2a is not particularly limited as long as it does not affect the liquid to be stored, and the material exemplified as the material of the bottle part 1 may be used. By providing the sheath 2a, the surface area of the exposed liquid absorbent core 2b can be reduced and leaching can be prevented. Needless to say, it is possible to prevent the seepage due to the fluctuation of the internal pressure of the bottle portion 1 when standing upright. The length of the sheath 2a may be set so that the contact area between the liquid and the liquid absorbent core 2b is kept constant from the phase in which the amount of liquid remaining inside is large to the phase in which it is small, and is exposed from the sheath 2a. The shorter the length of the liquid absorbent core 2b, the more the contact area is kept constant. That is, it is preferable that all the side surfaces of the liquid absorbent core 2b are covered with the sheath 2a inside the bottle portion 1, and the end of the sheath 2a may coincide with the position of the internal end of the liquid absorbent core 2b. More preferred. With this configuration, the liquid absorbent core 2b comes into contact with the liquid only at the end face of the inner end.

  However, in this case, in order not to prevent contact between the inner end of the liquid absorbent wick 2b and the liquid, the sheath 2a and the liquid absorbent wick 2b are separated from the bottom 1b of the bottle portion 1 so as not to contact the bottom 1b. There must be.

  On the other hand, by bringing the inner end of the liquid absorbent core 2b into contact with the bottom 1b of the bottle part 1, the position of the liquid absorbent part 2 can be stably maintained, and the liquid contained in the bottle part 1 can be retained. The liquid can be sucked up from the side surface of the liquid absorbent core 2b without any excess. In this case, it is necessary to expose the side surface of the liquid absorbent wick 2b from the sheath 2a. However, by reducing the length of the liquid absorbent wick 2b protruding from the tip of the sheath 2a as much as possible, the remaining amount of liquid is small. Except for the case, the contact area between the liquid and the liquid absorbent core 2b can be kept constant, and the liquid stored in the bottle portion 1 can be sucked up from the side surface of the liquid absorbent core 2b without leaving any excess. The length of the liquid absorbent core 2b protruding from the distal end of the sheath 2a may be set in consideration of the material of the liquid absorbent core 2b based on the amount of liquid to be sucked up per unit time. In addition, as shown in FIG. 4, it is preferable that the bottom face part 1b of the bottle part 1 is a shape where the directly under the lower end of the said liquid absorption core 2b was pushed down rather than the edge part. Thereby, since the liquid is collected in the vicinity of the liquid absorption core 2b protruding from the tip of the sheath 2a, the remaining amount of the liquid can be extremely reduced.

  A liquid-absorbing material may be used for the liquid-absorbent core 2b, such as synthetic fibers (for example, polyethylene, polypropylene, polyester, nylon, etc.), natural fibers (for example, cotton, linen, etc.), or composite materials thereof. Nonwoven fabric made of glass fiber, glass fiber, etc., and preferably non-woven fabric made of polyethylene, polypropylene, or polyester. The length of the liquid absorbent core 2b may be appropriately set in consideration of the length from the first opening 3 to the deepest part of the bottom 1b and the height protruding from the plug 2c.

  The plug portion 2c may be integrally configured as a part of the sheath 2a, or may be configured such that a member separate from the sheath 2a is bonded to the sheath 2a. In addition, as a structure necessary for sealing the first opening 3 with the liquid absorption part 2, for example, a groove, a protrusion, or the like may be provided in the first opening 3 and the plug part 2 c, respectively. . Furthermore, in order to facilitate the sealing of the first opening 3 by the liquid absorption part 2, the entire sheath 2a or the contact surface with the first opening 3 may be made of an elastic material, and the first opening The contact surface of the portion 3 with the plug portion 2c may be made of an elastic material.

  The breathable liquid sealing portion 5 that seals the second opening 4 is not particularly limited in material and shape as long as the breathable liquid sealing portion 5 has a breathability and does not allow water to pass through. In order to facilitate the configuration of the control device 10, an upper surface portion 1a or a stopper portion of the bottle portion 1 is made of a material having both air permeability and waterproofness (for example, a film of fluorine-containing polyethylene resin) via an adhesive layer. The structure fixed to 2c may be sufficient.

  Further, in order to prevent the liquid in the bottle part 1 from evaporating by the time when the pest control device 10 is used, a cap or seal that can be easily detached by the user is used until the outer end of the liquid absorbent core 2b and the liquid are used. It is preferable to cover the sealing portion 5.

  A pest control device 10 ′ shown in FIGS. 5 to 8 has a configuration similar to that of the pest control device 10 shown in FIGS. 1 to 4 and covers the upper surface portion 1 a and the liquid absorption portion 2 of the bottle portion 1. 7 is further provided. 5 to 7 are perspective views of the pest control apparatus 10 'according to the embodiment of the present invention, and FIG. 8 is a cross-sectional view of the pest control apparatus 10 according to the embodiment of the present invention. 1-4, since the liquid absorption core 2b is exposed on the outer surface of the bottle part 1, the infant may touch. As shown in FIG. 5, the pest control device 10 ′ further includes a cover portion 7 that functions as a child proof in order to eliminate such a possibility. The cover part 7 covers the upper part of the first opening part 3 and the second opening part 4 and is locked to the bottle part 1 with a gap between the cover part 7 and the bottle part 1. The cover part 7 has a locking part 7 a for securing to the bottle part 1. In the pest control device 10 ′ shown in FIG. 5, the convex portion 7b formed on the edge of the cover portion 7 communicates with the locking portion 7a, and the concave portion absorbs liquid from the outside of the pest control device 10 ′. An intrusion port 8 is formed for the dwarf sanitary pest to approach the core 2b. 6 and 7 show modifications in which the entrance 8 of FIG. 5 is widened. Of the leg portions 7b ′ and the hooking portions 7b ″ constituting the convex portion 7b, FIG. 6 shows an aspect in which the height of the leg portions 7b ′ is increased, and FIG. 7 shows the length of the hooking portion 7b ″. A lengthened embodiment is shown.

  The intrusion port 8 is not required to contain an infant's finger, and is preferably less than 13 mm. By having such a configuration, the pest control device 10 ′ can accidentally absorb the liquid absorbing wick from the outside of the bottle portion 1 without preventing the target dwarf sanitary pest from approaching the liquid absorbing wick 2 b. Touching 2b can be prevented.

  5-8, the cover part 7 of the structure which covers the whole surface is shown along the shape of the upper surface part 1a of the bottle part 1, but the infant's finger | toe of the cover part 7 of the bottle part 1 is shown. The upper part of the first opening 3 and the second opening 4 should be covered and locked to the bottle part 1 so as to avoid touching the liquid absorbing part 2, and the target dwarf sanitary insect pest is liquid absorbing wick. If it does not hinder the approach to 2b, the entire upper surface portion 1a may be covered or a part of the upper surface portion 1a may be covered.

A schematic diagram showing the relationship between the bottle part 1 and the cover part 7 is shown in FIG. When the cover portion 7 partially covers the upper surface portion 1a (FIG. 9a), that is, when the intrusion port 8 is defined by the upper surface portion 1a and the cover portion 7, a recess and / or at the edge of the cover portion 7 The convex part is not necessary. The distance d ₁ of the gap between the bottle part 1 and the cover part 7 may be a distance (3 mm or more) at which the target dwarf sanitary insect pest easily enters and exits. When the shortest distance d ₂ between the parts 7c and the bottle portion 1 than 6.5 mm, it is possible to improve the efficiency of creeping insect pests of interest approaches the wick 2b significantly.

Further, when the cover portion 7 covers the entire surface of the upper surface portion 1a (FIG. 9b), that is, when the entry port 8 is defined by the floor surface and the cover portion 7, a recess functioning as the entry port 8 is formed in the cover portion 7. It suffices if it is provided at the edge of the. The distance d ₁ of the gap between the bottle part 1 and the cover part 7 and the distance d ₃ between the end part 7c defining the entry port 8 in the cover part 7 and the floor surface d ₃ may be a cheap distance (more than 3mm), but when the shortest distance d ₄ between the end portion 1c and the cover part 7 of the bottle portion 1 than 6.5 mm, approaching creeping insect pests of interest to wick 2b Efficiency can be greatly improved.

  The cover portion 7 may have a cylindrical shape, a prismatic shape (cube or rectangular parallelepiped shape), a cone shape or a pyramid shape as in the bottle portion 1, and only the shape shown in FIGS. Instead, the shape shown in FIG. 10 may be used. In the cover portion shown in FIG. 10, an intrusion port 8 is formed in a direction perpendicular to the Z direction (mainly the X direction) in the drawing, and a region facing the liquid absorbing portion 2 is indicated by a virtual line.

  Further, in order to prevent the liquid in the bottle part 1 from evaporating by the use of the pest control device 10 ', the cap or seal that can be easily detached by the user is attached to the outer end of the liquid absorbent core 2b until the use. It is preferable to cover. When such a configuration is adopted, the pest control device 10 ′ may be provided separately from the bottle portion 1 and the cover portion 7. When the pest control device 10 ′ is used, the cover portion 7 removes the cap or the seal. What is necessary is just to be latched by the bottle part 1 which released | separated.

A polycup lid (diameter 10 cm) was placed on the shelter, and absorbent cotton soaked in water was placed. In order to prevent escape, full-on was pre-painted on the inner side. Separately, 20 black wagtails (10 males and 10 females) were released in a resin container, and the upper part of the resin container was covered with nylon goose and allowed to acclimate for about 24 hours. On the next day after release, one pest control device and one solid feed were placed in a resin container. Three days later, the number of dead insects in the resin container was examined, and the death rate was calculated. During the test period, the temperature inside the resin container was maintained at about 25 ° C. The treatment group was repeated twice, and the non-treatment group was repeated once. The death rate is shown below.

  If the shortest distance from the bottom end of the cover part 7 to the bottle part 1 is set to 6.5 cm or more, the death rate of cockroaches is remarkably improved. Therefore, when the distance is 6.5 cm or more, the liquid absorbent core It was found that cockroaches can be approached efficiently to 2b.

  By using the present invention, dwarf sanitary pests such as cockroaches that are sanitary pests can be safely controlled.
