Description

[Technical Field]

[0001] The present invention relates to liquid-filled ammunition and guns. [Background technology]

[0002] Various methods have been proposed for exterminating pests such as cockroaches when they are within sight. For example, there are methods for exterminating pests by hitting them with a stick-shaped object such as a fly swatter, methods for spraying pests with insecticide sprays, and methods for spraying adhesive resin compositions. There is also a method for firing granular material at pests using an insecticide gun.

[0003] Patent Document 1 discloses a fly swatter that catches cockroaches and other insects without crushing them. One side of the fly swatter has a frame with grooves carved into the inside that is tall enough to prevent cockroaches and other insects from being crushed. Single-sided adhesive paper is inserted into the groove, so that cockroaches and other insects are stuck to the adhesive paper when swatted without being crushed, and the adhesive paper can then be thrown away in a trash can or the like.

[0004] Patent Document 2 discloses a composition for capturing insects, which is sprayed onto insects with a resin composition for capturing insects that has a temporary initial adhesiveness after spraying but then becomes non-adhesive, thereby adhering to the insects and trapping them, and then becomes non-adhesive relatively quickly so that the insects can be easily wiped off. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Microfilm of Utility Model Application No. 57-160481 (Utility Model Application No. 59-113086) [Patent Document 2] Japanese Patent Application Publication No. 11-255603

[0006] However, when using a fly swatter to swat pests, the person trying to exterminate them must get close enough to the pest to be able to reach it with the fly swatter, and they may hesitate to get close enough to exterminate it. There is also the risk that the pest may escape while approaching, making it impossible to exterminate. Furthermore, if the pest is in a high place, it cannot be exterminated because the fly swatter cannot reach it.

[0007] Furthermore, the methods described in Patent Documents 1 and 2, which involve spraying insecticide sprays or adhesive resin compositions on pests, can repel pests from a distance, but sprayed droplets of insecticide or other liquids scatter around the area, requiring users to cover their face with goggles or a cloth and wear long sleeves to prevent the spray from coming into contact with the skin, such as the arms. Furthermore, when using insecticide sprays indoors, ventilation and wiping of floors and walls are required. Furthermore, spraying insecticide sprays is not considered desirable when there are infants or sick people in the room.

[0008] As mentioned above, spraying insecticide can kill pests from a distance, but it has a large impact on the surrounding area, and hitting them with a stick does not have an impact on the surrounding area, but the area in which it can be used is limited. For this reason, there has been no method that can capture and kill pests from a distance without affecting the surrounding area. Summary of the Invention [Problem to be solved by the invention]

[0009] To provide a means for capturing and exterminating pests even from a distance without affecting the surroundings. [Means for solving the problem]

[0010] The first means for solving the above problem is a liquid-filled bullet for capturing pests, which has a flexible bag body that deforms and bursts upon impact, and a liquid filled in the bag body for capturing pests.

[0011] A second means for solving the above problem is a gun that fires the above liquid-filled bullet, which has a barrel into which the liquid-filled bullet is loaded, and an ejection mechanism that ejects the liquid-filled bullet toward the tip of the barrel.

[0012] According to the present invention, pests can be captured and exterminated by bursting a liquid-filled bullet, which has a flexible bag that deforms and bursts upon impact, and a liquid filled in the bag for capturing pests. In addition, since the liquid-filled bullet can be fired from a gun, pests can be exterminated from a distance without affecting the surrounding area. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] First Embodiment <Liquid-filled bullets> A liquid-filled bullet 1 according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 3. The liquid-filled bullet 1 is spherical or bullet-shaped. In the following description, the spherical liquid-filled bullet 1 will be referred to as the first embodiment, and the bullet-shaped liquid-filled bullet 1 will be referred to as the second embodiment. FIG. 1 is a cross-sectional view of a liquid-filled bullet according to a first embodiment of the present disclosure. FIG. 2A is a front view of a sabot according to the first embodiment. FIG. 2B is a half-cross-sectional side view of a sabot according to the first embodiment. FIG. 3A is a cross-sectional side view showing the sabot of the liquid-filled bullet according to the first embodiment attached. FIG. 3B is a cross-sectional side view showing the sabot of the liquid-filled bullet according to a second embodiment of the first embodiment attached.

[0015] As shown in FIG. 1, the liquid-filled bullet 1 is a spherical bag 2 filled with a liquid 3 for capturing pests and sealed.

[0016] The bag 2 is filled with the liquid 3 and seals the liquid 3. The bag 2 is made of a flexible thin film. The bag 2 undergoes elastic deformation when deformed slowly. On the other hand, the bag 2 will burst if excessive stress is applied to it in a short period of time. The bag 2 can be made of, for example, polyethylene, vinyl, or rubber. The bag 2 is not limited to these materials, and any material can be used as long as it can be filled with the liquid 3 and sealed. The bag 2 may also be formed by coating the liquid 3.

[0017] The bag 2 has a spherical shape when filled with the liquid 3 and sealed. When filled with the liquid 3 and sealed, the bag 2 contains almost no air inside.

[0018] The liquid 3 can immobilize and capture the limbs of pest insects by dripping onto them. The liquid 3 is a sticky resin liquid. The liquid 3 may contain an insecticide 4.

[0019] Liquid 3 is a resin liquid obtained by diluting a sticky oil-soluble resin with an organic solvent. Examples of oil-soluble resins that can be used include polybutene, polyisobutylene, and natural rubber. Liquid 3 is not limited to these, and can be any sticky material, or a mixture of these materials. Examples of organic solvents that can be used include chlorinated perchloroethylene, trichlene, methyl chloroform, and deodorized kerosene.

[0020] Examples of insecticides that can be used as the insecticide 4 include boric acid, borates, and amidinohydrazone insecticides, as well as organophosphates, carbamates, pyrethroids, oxadiazoles, and phenylpyrazoles. The insecticide 4 may be a mixture of one or more of these insecticides. Alternatively, the insecticide 4 may be contained in the liquid 3 in the form of a microcapsule.

[0021] In an example of the liquid-filled bullet 1, the bag 2 may be a rubber balloon. In this case, the liquid 3 is injected into the liquid-filled bullet 1 through an inlet of the bag 2, and after filling, the inlet is closed and sealed. The same applies when the bag 2 is made of polyethylene or vinyl.

[0022] Alternatively, the liquid-filled bullet 1 may be formed by coating the bag 2 on the outer periphery of the liquid 3. In this case, the bag 2 is formed from a liquid containing sodium alginate and a calcium lactate solution. In this case, the bag 2 is manufactured by first applying an aqueous sodium alginate solution to the entire outer periphery of a spherical or bullet-shaped mass of liquid 3, and then submerging it until it is completely immersed in an aqueous solution in which calcium lactate has been dissolved, thereby forming a coating of sodium alginate and calcium lactate around the liquid 3. In this way, a liquid-filled bullet 1 is obtained in which the bag 2 is filled with the liquid 3.

[0023] The sabot 5 prevents the liquid-filled bullet 1 from exploding due to the impact when fired. As shown in Figures 2A and 2B, the sabot 5 is generally cylindrical in side view and has a recess 5a on the end surface that will be the tip side when loaded into the cylindrical gun. The recess 5a has a hemispherical portion 5b and a cylindrical portion 5c. The recess 5a also has a stopper 5d. The sabot 5 is made of a resin material. The sabot 5 is made by injection molding.

[0024] The hemispherical portion 5b forms the bottom of the recess 5a. The diameter of the hemispherical portion 5b is slightly larger than the diameter of the liquid-filled bullet 1, and the depth of the hemispherical portion 5b is the same as the radius of the liquid-filled bullet 1. The spherical portion 5b conforms to the shape of the rear end face of the liquid-filled bullet 1.

[0025] The cylindrical portion 5c has an inner circumferential surface that is continuous from the semispherical portion 5b to the end face. The diameter of the inner circumferential surface of the cylindrical portion 5c is the same as the diameter of the semispherical portion 5b.

[0026] The stopper 5d prevents the liquid-filled bullet 1 attached to the sabot 5 from accidentally ejecting. The stopper 5d is provided so as to protrude inward from the inner periphery of the cylindrical portion 5c. The height of the stopper 5d is shorter than the dimension between the outer periphery of the sabot 5 and the cylindrical portion 5c of the recess 5. Two stoppers 5 are provided at the tip of the recess 5a. The stopper 5d may be provided over the entire inner periphery of the recess 5a. Alternatively, the stopper 5d may be provided integrally with the cylindrical portion 5c. The stopper 5d may be formed to fit the shape of the front end face of the liquid-filled bullet 1.

[0027] The sabot 5 may have a split structure. In this case, the sabot 5 is composed of two members split along a plane passing through the axis of the cylindrical shape. The two members of the sabot 5 are combined at a split line 5e and attached to the liquid-filled bullet 1. The two members of the sabot 5 separate from the liquid-filled bullet 1 during flight after launch.

[0028] A second embodiment of the liquid-filled bullet may have a bullet-like shape. As shown in FIG. 3B, the liquid-filled bullet 1B has a pointed tip and a hemispherical rear end in a side view. The liquid-filled bullet 1B is symmetrical about a line connecting the tip and rear ends, and has a circular shape in a front view. The liquid-filled bullet 1B has a bullet-shaped bag 2B filled with liquid 3 and sealed.

[0029] When attached to the sabot 5, the liquid-filled bullet 1B is arranged so that its rear end faces the hemispherical portion 5b at the bottom of the recess 5a of the sabot 5.

[0030] The pointed tip of the liquid-filled bullet 1B reduces the effect of air resistance during flight, allowing the liquid-filled bullet 1B to fly straighter and improve the accuracy of hitting pests.

[0031] Second Embodiment <Gun> A gun according to a second embodiment of the present disclosure will be described below with reference to FIGS. 4 to 7. The gun 10 fires a liquid-filled bullet 1. The gun 10 can use a spring-activated air compression type, a low-pressure gas type, or a spring type as the ejection mechanism 110 for firing the liquid-filled bullet 1. In the following description, the ejection mechanism 110 of the gun 10 will be referred to as a first embodiment, a second embodiment, and a third embodiment, respectively, as a spring-activated air compression type, low-pressure gas type, and spring type. FIG. 4 is a schematic diagram of a gun according to the first embodiment of the present disclosure. FIG. 5A is a front view of an adapter according to the present disclosure. FIG. 5B is a side partial cross-sectional view of an adapter according to the present disclosure. FIG. 6 is a schematic diagram of a gun according to a second embodiment of the present disclosure. FIG. 7 is a schematic diagram of a gun according to a third embodiment of the present disclosure.

[0032] <First Example> The gun 10 according to the first embodiment is equipped with a spring-activated air compression ejection mechanism 110. The spring-activated air compression mechanism is a so-called air-cocking mechanism, in which a spring is manually compressed and air is compressed by the spring. As shown in FIG. 4, the gun 10 is equipped with a barrel 100, an ejection mechanism 110, a trigger 128, a grip 140, and a magazine 142. The ejection mechanism 110 is provided coaxially with the barrel 100 behind the barrel 100. The grip 140 is provided below the ejection mechanism 110, and the magazine 142 is provided inside the grip 140. The trigger 128 is also provided in front of the grip 140.

[0033] The barrel 100 pushes out and fires the liquid-filled bullet 1. The barrel 100 has a cylindrical bore 100a formed inside. The tip of the bore 100a forms the muzzle. An elastic ring 112 is attached to the inner peripheral wall of the rear end of the bore 100a. The inner diameter of the elastic ring 112 is approximately the same as the outer diameter of the liquid-filled bullet 1.

[0034] The ejection mechanism 110 ejects the liquid-filled bullet 1. As described above, the ejection mechanism 110 is a spring-activated air compression type. The ejection mechanism 110 is composed of a slider 116, a cylinder 118, and a piston 120.

[0035] The slider 116 constitutes the exterior of the extrusion mechanism 110. A cylinder 118 and a piston 120 are provided inside the slider 116. The slider 116 is configured to be manually slidable in the horizontal direction.

[0036] The cylinder 118 and the piston 120 constitute the air pump 114. The cylinder 118 is cylindrical with a bottom, and includes a cylindrical bottom and a cylindrical portion. The cylindrical bottom has a convex tip 118a. The cylindrical portion has a peripheral wall. The piston 120 is cylindrical with a bottom, and includes a cylindrical bottom and a cylindrical portion. A rubber gasket 122 is provided on the outside of the cylindrical bottom 120a. The cylinder 118 and the piston 120 are inserted coaxially with their cylindrical bottoms facing each other, and are freely slidable.

[0037] The tip of a piston spring 124 is attached to the inside of piston bottom portion 120a of piston 120. The rear end of piston spring 124 is attached to a cylinder stopper 126 provided on a shoulder inside the gun. Piston 120 has a piston engagement portion 120b on the upper side of the rear end, and the front surface of piston engagement portion 120b comes into contact with and engages with the rear surface of slider engagement portion 116a provided inside slider 116.

[0038] A locking hole 118c is formed in the lower part of the peripheral wall of the cylinder 118, and a fitting hole 120c is provided in the lower side of the peripheral wall of the piston 120. In addition, a swing stopper 134 pivotally supported by a bearing member 136 is provided on the outside of the outer peripheral wall of the cylinder 118.

[0039] The trigger 128 is pulled by the user's finger to fire the liquid-filled bullet 1. The trigger 128 is pivotally supported by a swing shaft 128a, and a support shaft 128b at the opposite end of the trigger 128 across the swing shaft 128a is pivotally supported by a connecting lever 130. The connecting lever 130 is pivotally secured to a rotating lever 132 by a support shaft 132a. The rotating lever 132 is L-shaped and is pivotally supported at its center by a rotating shaft 132b. The rotating lever 132 abuts against a swing stopper 134 at the end opposite the end where the support shaft 132a is located and the end where the rotating shaft 132b is located. The swing stopper 134 is rod-shaped and pivotally supported by a bearing member 136, and has a tip claw 134a at the end opposite the portion pivotally supported by the bearing member 136 on the side where the rotating lever 132 abuts. One end of a coil spring 138 is attached below the tip claw 134a of the swing stopper 134. The other end of the coil spring 138 is attached inside the gun grip 140, and urges the tip claw 134a upward.

[0040] The handle 140 is held by the user of the gun 10. The user can pull the trigger 128 with their finger while holding the handle 140 in their palm. A magazine 142 is removably attached inside the handle 140. The magazine 142 has a pusher member 144 that is actuated upward by a pusher spring 146 at the bottom. The magazine 142 stores multiple liquid-filled bullets 1. Here, if the liquid-filled bullets 1 are equipped with sabots 5, the magazine 142 stores the liquid-filled bullets 1 with the sabots 5 attached.

[0041] The gun 10 may have a protrusion 100c in the barrel 100b for dividing the sabot 5. The height of the protrusion 100c from the inner peripheral surface of the barrel 100b is lower than the distance from the outer peripheral surface of the sabot 5 to the recess 5a. The protrusion 100c has a flat shape in top view, and is provided so that its longitudinal direction is parallel to the axial direction. The protrusion 100c may have a pointed shape on the loading section 100b side in top view.

[0042] The protrusions 100c are provided at two locations on the inner circumferential surface of the gun bore 100a. The protrusions 100c are provided in front of the liquid-filled bullet 1 equipped with the sabot 5 attached to the attachment portion 100b in the axial direction of the gun bore 100b. The protrusions 100c are provided in a position corresponding to the parting line 5e of the liquid-filled bullet 1 equipped with the sabot 5 attached to the attachment portion 100b in the circumferential direction of the axis of the inner circumferential surface of the gun bore 100b.

[0043] The ejection mechanism 110 may include an adapter 110a. Similar to the sabot 5, the adapter 110a ejects the liquid-filled bullet 1 while preventing it from exploding due to the impact of firing. As shown in FIGS. 5A and 5B, the adapter 110a is generally cylindrical in side view and includes a recess 110a1 on its end surface, which will be the tip end when the cylindrical bullet is loaded into a gun. The recess 110a1 has a hemispherical portion 110a2 and a cylindrical portion 110a3. The adapter 110a is made of, for example, a resin material. The adapter 110a is manufactured by, for example, injection molding. The liquid-filled bullet 1 attached to the adapter 110a is attached so that its rear end faces the spherical surface 110a2 at the bottom of the recess 110a1 of the adapter 110a, just like when it is attached to the sabot 5.

[0044] The spring-activated air compression system will be explained below. Figure 4 shows the initial state, with the slider 116 positioned at the rear of the barrel 100 and the nose 118a of the cylinder 118 connected to the elastic ring 112 at the rear end of the barrel 100. Also, the cylinder 118 and piston 120 are not yet in their stroke, with their bottoms approaching each other, the volume of the front chamber 118b is small, and the piston spring 124 is in an extended state.

[0045] Next, when the user slides the slider 116 rearward, the slider engagement portion 116a of the slider 116 presses the piston engagement portion 120b, moving the piston 120 rearward. Further sliding the slider 116 rearward also moves the piston 120 rearward, compressing the piston spring 124. At this time, the cylinder 1118 also moves rearward along with the piston 120, and the nose portion 118a is separated from the elastic ring 112 of the bore 100a. Meanwhile, the locking hole 118c of the cylinder 118 is restricted by the tip claw 134a, preventing it from moving rearward beyond a certain point. This causes the piston 120 to stroke relative to the cylinder 118, drawing air into the front chamber 118b of the cylinder 118. A liquid-filled bullet 1 is loaded into the loading portion 100b at the rear end of the barrel 100 through the bullet supply port 142a of the magazine 142. The piston 120 is locked in place as the fitting hole 120c engages with the tip claw 134a, and remains in that position.

[0046] Next, when the user returns the slider 116 to its original position, the cylinder 118 returns to its original position and the nose 118a connects to the elastic ring 112. Here, the nose 118a pushes the liquid-filled bullet 1 loaded from the magazine 142 into the elastic ring 112, connecting the nose 118a to the elastic ring 112. As a result, the space from the liquid-filled bullet 1 in the bore 100a to the packing 122 of the piston 120, i.e., the nose 118a and the front chamber 118b, are sealed. While the cylinder 118 and the piston 120 are in a stroke state, the piston spring 124 is compressed.

[0047] When the trigger 128 is pulled in this state, the connecting lever 130 moves forward, causing the swing stopper 134 to swing clockwise via the rotating lever 132, disengaging the tip pawl 134a from the fitting hole 120c. As a result, the piston 120 strokes forward under the force of the expanding piston spring 124. The piston 120 is urged forward by the compressed piston spring 124, compressing the air in the front chamber 118b of the cylinder 118, increasing its pressure. This forces the air in the front chamber 118b out and ejects it from the nose 118a. The air ejected from the ejection port pressurizes the liquid-filled bullet 1 in the loading section 100b of the bore 100a. The pressurized liquid-filled bullet 1 passes through the elastic ring 112, advances through the bore 100a, and is fired from the muzzle.

[0048] <Second Example> A gun 10B according to a second embodiment will be described below. In the gun 10B according to this embodiment, the extrusion mechanism 210 is gas-powered. As shown in FIG. 6, the gun 10B includes a gas cylinder 220 filled with compressed gas. The gas cylinder 220 is connected to a flow path leading to a pressurizing chamber 212 at the rear end of the gun bore 200a. A valve 214 is provided in the flow path, and the gas in the gas cylinder 220 is blocked by the valve 214. In the description of this embodiment, details common to the first embodiment will be omitted.

[0049] When trigger 222 is pulled, hammer 216 swings in conjunction with the trigger, causing hammer nose 218 connected to hammer 216 to strike the shaft of valve 214. This opens valve 214, allowing gas in gas cylinder 220 to pass through valve 214 and be sent into pressurization chamber 212 at the rear end of bore 200a. Liquid-filled bullet 1 is pushed out by the pressure of the gas in pressurization chamber 212 and fired.

[0050] <Third Example> A gun 10C according to a third embodiment will now be described. The gun 10C of this embodiment has a spring-type ejection mechanism 310. As shown in FIG. 7, the gun 10C includes a striking rod 312 in a guide hole 310a behind a loading section 300b of a gun bore 300a. A housing chamber 310b behind the guide hole 310a includes an ejection spring 314 that biases a flange 312a at the rear end of the striking rod 312. The rear end of the housing chamber 310 is closed by a screw 316 and a female screw 318. The striking rod 312 is locked by engaging the flange 312a with a left shoulder 320b of an engagement piece 320. The engagement piece 320 is pivoted to a swing rod 322 by a swing shaft 320a and is biased by a spring 324 provided in a hole 322b of the swing rod 322. The swing rod 322 is pivoted by a swing shaft 322a and is swingable. A guide groove 326 that guides the engagement piece 320 is provided below the chamber 310b. The rear end 326a of the guide groove 326 is inclined downward. A roller provided at the end of the trigger 330 abuts the front surface of the swing rod 322, and one end of a helical spring 328 abuts and biases the swing rod 322 against a groove 322c provided on the rear surface. The trigger 330 is protected by a protective frame 334b. The helical spring 328 is attached to a support 334a provided inside the handle 334, and the other end abuts against the inner wall of the handle 334. The lower part of the barrel 300 is provided with a bullet storage hole 338 and a bullet supply hole 300c that communicates with the bore 300a. The liquid-filled bullet 1 in the bullet storage hole 338 is supplied to the bullet supply hole 300c by the swinging of the protruding piece 336 pivoted on the swing shaft 330a. In the explanation of this embodiment, the contents common to the first embodiment will be omitted.

[0051] When the trigger 330 of the gun 10C is pulled, the roller 332 swings counterclockwise and presses the swing rod 322. As the swing rod 322 swings clockwise, the engagement piece 320, which is pivoted to the tip of the swing rod 322, moves rearward along the guide groove 326. The striking rod 312, whose left shoulder 320b and flange 312a are engaged, is pulled rearward, compressing the ejection spring 314. When the engagement piece 320 reaches the rear end 326a, the engagement between the left shoulder 320b and flange 312a is released. This causes the compressed ejection spring 314 to return to its original length, expelling the liquid-filled bullet 1 loaded in the loading section 300b of the gun bore 300a. When trigger 330 is pulled, protrusion 336 swings counterclockwise, scooping up liquid-filled bullet 1 from bullet storage hole 338. When trigger 330 is released, swing rod 322 and protrusion 336 return to their original positions, and left shoulder 320b of locking piece 320 engages with flange 312a of striking rod 312. Liquid-filled bullet 1 is then fed through bullet supply hole 300c into bore 300a and loaded into loading section 300b.

[0052] <Firing process> An example of a process for firing a liquid-filled bullet 1 according to the present disclosure from a gun 10 will be described below with reference to Fig. 4 and Figs. 8A to 8D. Figs. 8A to 8D are schematic diagrams illustrating a process for firing a liquid-filled bullet equipped with a sabot according to the present disclosure from a gun. Note that, although the description uses the reference numerals of the gun 10A according to the first example embodiment in some parts, this is not limited to the gun according to the first example embodiment, and guns according to the other examples also follow a similar firing process.

[0053] As shown in FIG. 8A, a spherical liquid-filled bullet 1 with a sabot 5 attached is loaded into the loading section 100b of the bore 100a inside the barrel 100 of the gun 10. Specifically, the sabot attached to the liquid-filled bullet 1 is pushed into an elastic ring 112 provided on the inner peripheral wall at the rear end of the bore 100a. Here, the hemispherical section 5b of the recess 5a of the sabot 5 conforms to the shape of the rear end of the liquid-filled bullet 1. Compressed air is stored in an ejection mechanism 110 (not shown). The muzzle of the gun 10 is pointed toward a pest T on a wall W.

[0054] Next, when trigger 128 (not shown) is pulled, the engagement between fitting hole 120c of piston 120 of ejection mechanism 110 and tip claw 134a is released, and the restoring force of compressed piston spring 124 causes piston 120 to eject air from front chamber 118b through nose section 118a, pushing the rear end of sabot 5 loaded in loading section 100b toward the tip of bore 100a.

[0055] Compressed air from the ejection mechanism 110 pushes the rear end surface of the sabot 5, transmitting force from the hemispherical portion 5b of the recess 5a of the sabot 5 to the liquid-filled bullet 1. The liquid-filled bullet 1 cannot deform within the recess 5a due to the force received from the sabot 5, and therefore does not explode. The liquid-filled bullet 1 travels through the barrel 100b together with the sabot 5 and is fired from the muzzle at the tip. As shown in FIG. 8B, the sabot 5 passes over a protrusion 100c provided on the barrel 100b, and is separated by the protrusion 100c along a parting line 5e.

[0056] As shown in Figure 8C, the liquid-filled bullet 1 fired from the gun 10 flies due to inertia. Meanwhile, the sabot 5, which is separated into two by the protrusion 100c, flies out from the tip of the gun bore 100a, separates from the liquid-filled bullet 1, loses speed due to air resistance, and eventually falls. The liquid-filled bullet 1 fired from the gun 10 flies until it hits the point of impact.

[0057] As shown in Figure 8D, when liquid-filled bullet 1 hits wall W, the impact point, a change in momentum in a very short period of time causes the shape of liquid 3 to change dramatically into an approximately disk shape. This deformation of liquid 3 causes a localized force exceeding the allowable stress in bag 2, causing it to burst. Liquid 3 spills out of burst bag 2 and falls on the limbs of the pest, which then locks the limbs together with the liquid 3, or locks the limbs to wall W, immobilizing and trapping the pest.

[0058] <Other Examples> Another example of a process for firing a liquid-filled bullet 1 according to the present disclosure from a gun 10 will be described below with reference to Figures 9A and 9B. Figures 9A and 9B are schematic diagrams illustrating a process for firing a liquid-filled bullet according to the present disclosure from a gun equipped with an adapter. In this example, the ejection mechanism 110a of the gun 10 is equipped with an adapter 110a, and the liquid-filled bullet 1 does not have a sabot 5 attached. Note that in this explanation, explanations of parts that overlap with the firing process according to the above example will be omitted.

[0059] As shown in FIG. 9A, an adapter 110a is provided in a loading section 100b of a bore 100a inside a barrel 100 of a gun 10, and a spherical liquid-filled bullet 1 is loaded into a recess 110a1 of the adapter 110a. Specifically, the adapter 110a is pressed into an elastic ring 112 provided on the inner peripheral wall at the rear end of the bore 100a, and the liquid-filled bullet 1 is loaded by being pressed into the adapter 110a. Here, a hemispherical section 110a2 of the recess 110a1 of the adapter 110a conforms to the shape of the rear end of the liquid-filled bullet 1. Compressed air is stored in an ejection mechanism 110 (not shown).

[0060] Next, when trigger 128 (not shown) is pulled, the engagement between fitting hole 120c of piston 120 of ejection mechanism 110 and tip claw 134a is released, pushing adapter 110a loaded in loading section 100b along with liquid-filled bullet 1 toward the front of bore 100a. At this time, the rear end of adapter 110a receives the force of compressed air, and the hemispherical portion 110a2 of recess 110a1 of adapter 110a contacts and transmits the force to liquid-filled bullet 1. Because liquid-filled bullet 1 attached to adapter 110a cannot deform within recess 110a2 due to the impact of firing, it does not explode. The liquid-filled bullet 1 travels through bore 100b together with adapter 110a and is fired from the muzzle at the front. As shown in Figure 9B, adapter 110a is stopped by stopper 100d at the front of bore 100a. Meanwhile, the liquid-filled bullet 1 is ejected from the recess 110a of the adapter 110a due to inertia, and then the liquid-filled bullet 1 separates from the adapter 110a, ejects from the tip of the gun bore 100a, and is fired.

[0061] As shown in Figure 9B, a liquid-filled bullet 1 fired from a gun 10 flies due to inertia and hits a wall surface W at the impact point. When the liquid-filled bullet 1 hits, the bag body 2 deforms and bursts, causing the liquid 3 to splash out. The splashed liquid 3 binds the limbs of the pest T to each other or to the wall surface W, trapping the pest T.

[0062] <First aspect> The liquid-filled bullet 1 according to the first aspect of the present disclosure is a liquid-filled bullet for capturing pests, and has a flexible bag body 2 that deforms and bursts upon impact upon collision, and a liquid 3 filled in the bag body for capturing pests. According to the first aspect, the liquid-filled bullet 1 is constructed by filling a liquid 3 for capturing pests into a flexible bag body 2 that deforms and bursts upon impact upon impact, so that when the bullet is fired and hits a wall or the like, the bag body deforms and bursts, allowing the liquid to fly out and capture pests. <Second aspect> In the second embodiment, the liquid-filled bullet 1 according to the first embodiment has a spherical or bullet shape. According to the second aspect, the liquid-filled bullet 1 has a spherical or bullet-like shape, so that the influence of air resistance during flight can be suppressed. <Third aspect> The third aspect is a liquid-filled bullet 1 according to the second aspect, which is provided with a sabot 5 having a semi-spherical portion 5b on the rear end surface. According to the third aspect, the liquid-filled bullet 1 is provided with the sabot 5 having the semispherical portion 5b on the rear end surface, so that the bag body 2 can be prevented from being deformed and bursting due to the impact at the time of firing. <Fourth aspect> In a fourth aspect, in the liquid-filled bullet 1 according to the first aspect, the liquid 3 is viscous. According to the fourth aspect, the liquid-filled bullet 1 has a sticky liquid 3, so that the limbs of pests to which the liquid 3 is attached are immobilized and the pests can be trapped. Furthermore, when a pest is trapped with a sufficient amount of liquid 3, the sticky liquid 3 closes the spiracles of the pest, suffocating the pest. <Fifth aspect> A fifth aspect is a liquid-filled bullet 1 according to the first aspect, wherein the liquid 3 comprises an insecticide 4. According to the fifth embodiment, the liquid-filled bullet 1 can kill the captured pests because the liquid 2 contains the insecticide 4. <Sixth aspect> A sixth aspect of the present disclosure is a gun 10 that fires a liquid-filled bullet 1 having a bag body 2 filled with a liquid 3 for capturing pests, and has a barrel 100b into which the liquid-filled bullet 1 is loaded, and an extrusion mechanism 110 that extrudes the liquid-filled bullet 1 toward the tip of the barrel 100b. According to the sixth aspect, the gun 10 has a barrel 100a into which a liquid-filled bullet 1 is loaded, and an ejection mechanism 110 that pushes the liquid-filled bullet 1 toward the tip of the barrel 100b, so that the liquid-filled bullet 1 can be fired from the tip of the barrel 100b by the ejection mechanism 110. <Seventh aspect> In a seventh aspect, in the gun 10 according to the sixth aspect, the ejection mechanism 110 is of a low-pressure gas type, an air compression type, or a spring type. According to the seventh embodiment, the gun 10 can be used without affecting the surroundings because the ejection mechanism 110 is a compressed gas type, a spring-activated air compression type, or a spring type. <Eighth aspect> In the eighth aspect, in the gun 10 according to the sixth aspect, the ejection mechanism 110 includes an adapter shaped to fit the rear end of the liquid-filled bullet 1. According to the eighth aspect, the gun 10 has an extrusion mechanism 110 equipped with an adapter 110a shaped to fit the rear end surface of the liquid-filled bullet 110, so that the bag body 2 of the liquid-filled bullet 1 can be prevented from being deformed by the impact at the time of firing, and will not burst.
