Japanese Utility Model Publication No. 1-161655

  However, in the aerosol injection device 100 disclosed in the above-mentioned Patent Document 1, when a hole that allows invasion of harmful animals such as spiders and snakes, and pests such as mites, cockroaches, and white ants is plugged, the intrusion is prevented. When the above-mentioned mixed liquid is sprayed around the permissible entrance / exit, the nozzle 102 may not reach the entrance / exit.

  For this reason, the liquid mixture is injected at a location away from the aforementioned entrance and exit, and the mixed liquid is not efficiently injected into the entrance and exit, and a lot of liquid mixture is required to block the entrance and exit, which is a waste. May occur.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an aerosol injection device capable of accurately and efficiently injecting aerosol contents to a desired location, and a button attached to the aerosol injection device. It is to provide.

The above-described object of the present invention is achieved by the following configuration.
(1) an aerosol container containing the aerosol contents;
A valve stem provided at an end of the aerosol container and extending in the axial direction of the aerosol container;
A button having its own button base end attached to the tip of the valve stem in order to eject the aerosol contents from the tip of the valve stem;
A long pipe attached to the button;
An aerosol spray device comprising:
The button is formed hollow from the button proximal end to the button distal end to guide the aerosol contents ejected from the distal end of the valve stem, and the long pipe is detachable. A pipe fitting part for fitting is provided at the button tip part, and the lever part is provided on the button side part so as to extend to the side part of the aerosol container and fully open the valve stem at the time of use. An aerosol injection device characterized by that.
(2) The ratio between the inner diameter of the valve stem and the inner diameter of the long pipe is set so that the inner diameter of the long pipe is 0.5 or more when the inner diameter of the valve stem is 1. (1) The aerosol injection device according to the above.
(3) The tip of the lever portion is provided so as to be located obliquely above the end of the aerosol container in a state where the valve stem of the aerosol container is directed downward. The aerosol injection device according to the above (1) or (2).
(4) The aerosol content in the aerosol container is an aerosol composition containing a harmful animal repellent, a hard foam raw material, and a propellant,
The long pipe is used to be directed toward the hole to allow the entry of harmful animals, and the lever portion is operated in a state where the valve stem of the aerosol container is directed downward. Thus, the aerosol composition is injected into the air and cured to form a hard foam containing the harmful animal repellent, and the hard foam closes the hole. The aerosol injection device according to any one of (1) to (3) above.
(5) In order to eject the contents of the aerosol contained in the aerosol container from the tip of the valve stem provided at the end of the aerosol container and extending in the axial direction of the aerosol container. A button that can be attached to the tip of the button at the base end of the button,
In order to guide the aerosol contents ejected from the distal end portion of the valve stem, it is formed hollow from the button proximal end portion to the button distal end portion, and for detachably fitting a long pipe It has a pipe fitting portion at the button tip portion, and is formed to extend to the side portion of the aerosol container, and has a lever portion at the button side portion for fully opening the valve stem at the time of use. button.

According to the configuration of the above (1), the end of the long pipe fitted to the pipe fitting part of the button is brought close to the entrance / exit allowing the entry of harmful animals (including pests), and then the lever part is aerosolized. By operating toward the container, the aerosol contents can be intensively sprayed around the entrance / exit, that is, at a desired location. At this time, if a long pipe with a large diameter is used as the long pipe, an injection amount corresponding to the opening area can be obtained for a relatively large entrance / exit. On the other hand, if a long pipe having a small diameter is used as the long pipe, an injection amount corresponding to the opening area can be obtained for a relatively small entrance / exit.
In addition, the lever part extends to the side of the aerosol container and is formed to fully open the valve stem at the time of use, so that the valve stem can be operated sufficiently with a smaller force for the length. The desired injection amount can be obtained with certainty. For this reason, efficient injection can be performed.
According to the configuration of (2) above, the ratio of the inner diameter of the valve stem to the inner diameter of the long pipe is such that the inner diameter of the long pipe is 0.5 or more when the inner diameter of the valve stem is 1. Therefore, the progress of the curing of the aerosol contents in the valve stem and in the long pipe can be suppressed, and efficient injection can be performed for a long time without causing clogging or the like. it can. In addition, it is good to process a mold release agent in these pipes beforehand. At this time, it is preferable to treat the inner surface of these pipes with a release agent.
According to the configuration of (3) above, the tip of the lever portion is provided obliquely above the end of the aerosol container with the valve stem of the aerosol container facing downward. Therefore, for example, when the valve stem is used while being directed downward, the user can operate the lever portion while gripping the aerosol container, that is, the main body of the aerosol injection device. For this reason, efficient injection can be performed and usability can be improved.
According to the configuration of (4) above, the aerosol content is an aerosol composition including a harmful animal repellent, a raw material for rigid foam, and a propellant, and is a length disposed below the aerosol container. By moving the end of the shank pipe closer to the entrance allowing the entry of harmful animals and then operating the lever part toward the aerosol container, the aerosol composition adheres around the entrance allowing the entry of harmful animals. It hardens to form a hard foam containing a pest repellent, and the hard foam closes the doorway.
According to the configuration of the above (5), the lever portion is moved to the aerosol after the end of the long pipe fitted to the pipe fitting portion of the button is brought close to the entrance / exit allowing entry of harmful animals (including pests). By operating toward the container, the aerosol contents can be intensively sprayed around the entrance / exit, that is, at a desired location. At this time, if a long pipe with a large diameter is used as the long pipe, an injection amount corresponding to the opening area can be obtained for a relatively large entrance / exit. On the other hand, if a long pipe having a small diameter is used as the long pipe, an injection amount corresponding to the opening area can be obtained for a relatively small entrance / exit.
In addition, since the lever part is formed to extend to the side part of the aerosol container and is formed to fully open the valve stem at the time of use, the valve stem can be sufficiently operated with a smaller force for the length. Thus, a desired injection amount can be obtained with certainty. For this reason, efficient injection can be performed.

Here, in the present invention, the propellant described above may be either compressed gas or liquefied gas. Examples of the compressed gas include carbon dioxide gas, nitrogen gas, and compressed air. In addition, examples of the liquefied gas include liquefied petroleum gas, dimethyl ether, propane, butane, liquefied CO ₂ , and liquefied N ₂ . Moreover, you may use the mixed gas of compressed gas and liquefied gas as a propellant. The blending amount may be a blending amount capable of injecting the aerosol contents in the aerosol container from the aerosol spraying device, and may be in a range of 5 parts by weight to 90 parts by weight that does not hinder the implementation of the present invention.

  Further, in the present invention, the aerosol contents in the aerosol container can include an aerosol composition containing an animal repellent and a raw material for rigid foam in addition to the above-mentioned propellant, but further if necessary. Various solvents, additives and the like may be included. For example, a foamed polyurethane aerosol composition can be used as the aerosol composition. Polyurethane foam resin is not only excellent in abrasion resistance, chemical resistance and adhesion of polyurethane resin, but also excellent in elasticity, heat insulation, sound insulation, etc., and widely used as heat insulation material for factories and buildings It has been. The foamed polyurethane resin is roughly classified into a one-component curable type and a two-component curable type. Specific examples of these are one-component curable type using a prepolymer, polyol and polyisocyanate. And a two-component curing type. For example, in the case of a one-component curable type using a prepolymer, a one-component foamed polyurethane aerosol composition contained in an aerosol container basically comprises a urethane prepolymer and a propellant as raw materials for a hard foam. A polyurethane foam is formed by being injected and cured from an aerosol injection device.

  Therefore, in the present invention, examples of the hard foam material used for the aerosol composition include one-pack type or two-pack type hard foam polymer, hard foam prepolymer, and hard foam monomer. The one-pack type is preferable because it is superior in terms of usability. The blending amount may be in the range of 5 parts by weight to 90 parts by weight as long as the implementation of the present invention is not hindered. Here, the term “hard” refers to a hardness that allows the formed foam to be cut horizontally or perpendicularly to the processing surface with a sharp blade such as a cutter. And the typical thing of the raw material for hard foams (in other words, the raw material for hard foamed resin) is the above-mentioned urethane prepolymer. For example, a suitable foamed polyurethane aerosol composition can be obtained from 40 to 99 parts by weight of urethane prepolymer and 1 to 60 parts by weight of a propellant composed of at least one of a liquefied gas and a compressed gas. In addition, you may mix | blend a solvent as needed.

  Examples of the solvent generally include water, alcohols such as methyl alcohol and ethyl alcohol, glycols, ketones such as acetone and methyl ethyl ketone, ethers such as tetrahydrofuran and dioxane, hexane, kerosene, paraffin, and kerosene. Etc. can be used. These solvents may be used alone or in combination of two or more.

  Further, a pest repellent may be mixed with an amino resin such as melamine resin and microencapsulated so as to be scattered in the foam. In this way, the persistence of the harmful animal repellent effect is increased.

  In the present invention, harmful animal repellents include pepper powder, capsaicin (for example, nordihydrocapsaicin I, dihydrocapsaicin, homodihydrocapsaicin I, nordihydrocapsaicin II, homodihydrocapsaicin II, capsaicin, homocapsaicin I, homocapsaicin II. Etc.), powder paste, terpineol, camphor, wasabi, allyl isothiocyanate, thymol, rosemary extract and the like.

  Capsaicins also have a repellent effect against white ants and other pests.

In addition, the amount of the harmful animal repellent-containing rigid foamed urethane resin used in the method for repelling harmful animals using the aerosol spray device of the present invention is the content of the harmful animal repellent component in the urethane resin, the application method, the application location, etc. The amount to be applied per hole cm ^{2 at} the entrance / exit of the sputum is usually 0.05 g, preferably 0.1 g to 0.5 g, in this case harmful animal repellent component The amount of the active ingredient may be 1 mg to 50 mg.

  In the present invention, the harmful animals to be repelled are not particularly limited, and examples thereof include spiders, spiders, and earth dragons. Examples of insect pests include cockroaches, termites, ants and other insect pests, centipede, geji and other insect pests, and insects which easily enter holes such as bees and abs (these are also harmful animals).

  ADVANTAGE OF THE INVENTION According to this invention, the button attached to the aerosol injection apparatus which can inject an aerosol content to a desired location accurately and without waste, and an aerosol injection apparatus can be provided.

It is good to have.

  By setting in this way, the lever portion 11 has a three-dimensional shape that allows the valve stem 3 to be fully opened at the time of use. In addition, in a state where the valve stem 3 of the aerosol container 2 is directed downward, the distal end portion of the lever portion 11 is provided so as to be positioned obliquely upward with respect to the end portion of the aerosol container 2 (for example, FIG. reference).

  As shown in FIG. 5, a male screw portion 12 is formed on the outer peripheral surface of the pipe fitting portion 9.

  As shown in FIG. 6, an internal thread portion 13 is formed on the inner peripheral surface of the valve stem screw insertion portion 10. The body 7 has an upper inner diameter of, for example, 4.0 mm to 6.0 mm, a length of, for example, 10.0 mm to 30.0 mm, and a lower inner diameter of, for example, 5.0 mm to 7 mm. And the length dimension is, for example, 24.0 mm to 30.0 mm.

  As shown in FIG. 7, the bent portion 8 has an upper inner diameter of 3.3 mm to 5.3 mm, for example, and a lower inner diameter of 2.5 mm to 4.5 mm, for example.

  As shown in FIG. 8, the large diameter long pipe 5 is detachably attached to the pipe fitting portion 9 of the button 4. The large-diameter long pipe 5 has a base end portion into which the male screw portion 12 of the pipe fitting portion 9 is screwed (more specifically, the large-diameter long pipe 5 is rotated along the male screw portion 12. The base end portion covers the male screw portion 12). The large-diameter long pipe 5 has an inner diameter of 2.0 mm to 10.0 mm, for example, and a length of 5.0 cm to 30.0 cm. The tip of the large-diameter long pipe 5 is an injection port 14. The shape of the injection port 14 is not limited to a circular shape, and may be appropriately selected according to the shape of the entrance / exit allowing the entry of harmful animals, such as an oval shape or a slit. The large-diameter long pipe 5 is easily detached from the pipe fitting portion 9 by being rotated in the anti-screwing direction.

As shown in FIG. 9, the button 4 is attached to the valve stem 3 at the valve stem screwing portion 10. The valve stem 3 has a male screw portion 15 that is screwed into the valve stem screwing portion 10 of the button 4, and is attached to the valve mounting portion 17 of the mountain cap 16 via a seal rubber 18 that also functions as a holder.
The mountain cap 16 is provided to increase the stability of the aerosol contents.

The seal rubber 18 is formed of, for example, a rubber material having a predetermined elasticity. For this reason, the valve stem 3 is always positioned at a neutral position where the seal rubber 18 stands in the axial direction of the aerosol container 2 due to the elasticity of the seal rubber 18. Yes. The lower end portion of the valve stem 3 is provided with a flange portion 20 that is engaged with the seal rubber 18 at one end surface thereof. In addition, four communication holes 19 are provided at predetermined intervals in the peripheral edge of the flange 20 to introduce the aerosol contents.
In the aerosol injection device 1 configured as described above, the aerosol content (that is, the remaining liquid) remaining in the bubble stem 3 after the operation is obtained by injecting only the gas by erecting the aerosol container 2, It is easily removed from the bubble stem 3. That is, according to the aerosol injection device 1 of the present embodiment, it is possible to easily prevent the residual liquid in the bubble stem 3 from being cured.

  Further, the ratio of the inner diameter D1 of the valve stem 3 to the inner diameter D2 of the large long pipe 5 is such that the inner diameter D1 of the valve stem 3 is 1, and the inner diameter of the large long pipe 5 is 1. D2 is set to be 0.5 or more.

  As shown in FIG. 10, a small-diameter long pipe 6 can be detachably attached to the pipe fitting portion 9 of the button 4 instead of the large-diameter long pipe 5. The small-diameter long pipe 6 has an outer diameter dimension of, for example, 4.0 mm to 6.0 mm so as to be inserted into the inner peripheral portion of the pipe fitting portion 9 and has a length of, for example, 5.0 cm to 30.0 cm. Have dimensions. The small-diameter long pipe 6 is easily removed from the pipe fitting portion 9 by being pulled out. Also in this case, the inner diameter D3 of the small-diameter long pipe 6 is set to be 0.5 or more when the inner diameter D1 of the valve stem 3 is 1.

  Next, with reference to FIGS. 11 and 12, a method of using the aerosol injection device 10 will be described.

  First, the aerosol spray device 10 is shaken well with the hand. Thereby, the undiluted | stock solution in the aerosol container 2 and a propellant are stirred and mixed. In addition, when the stirring ball (not shown) is accommodated in the aerosol container 2, the said stirring ball acts so that a stock solution and a propellant may be stirred and mixed.

  Then, as shown in FIG. 11, the aerosol injection device 10 (so that the large-diameter long pipe 5 (small-diameter long pipe 6) faces downward, that is, the valve stem 3 of the aerosol container 2 faces downward. The aerosol container 2 is sandwiched between the thumb and forefinger of the hand upside down (see FIG. 1), and the remaining three fingers are hooked on the lever portion 11.

  Then, after the injection port 14 of the large-diameter long pipe 5 is inserted into an entrance / inlet that allows entry of harmful animals (including pests), the lever portion 11 is pulled toward the aerosol container 2.

  As shown in FIG. 12, since the lever portion 11 has a three-dimensional shape that allows the valve stem 3 to be fully opened, the lever portion 11 is operated so as to approach the side portion of the aerosol container 2. The valve stem 3 is tilted against this, whereby the aerosol content in the aerosol container 2 is fed from the communication hole 19 into the valve stem 3 and from the button 4 into the large-diameter long pipe 5. From the injection port 14 (refer FIG. 1 etc.), it injects to the circumference | surroundings of the entrance / exit which permits invasion of a harmful animal.

  At this time, since the large-diameter long pipe 5 has a large diameter, the relatively large entrance / exit is closed with an injection amount corresponding to the opening area.

  Further, since the lever portion 11 is formed to extend to the side portion of the aerosol container 2 and is formed so as to fully open the valve stem 3 at the time of use, it does not contact the aerosol container 2 with a smaller force for its length. In the range, the valve stem 3 can be operated sufficiently. For this reason, a desired injection amount can be obtained with certainty and efficient injection is performed.

  After the injection is finished, when the finger is released from the lever portion 11, the urging spring 19 returns the valve stem 3 to the neutral position where it rises in the axial direction of the aerosol container 2.

  And when the period of non-use passes, the aerosol content (that is, residual liquid) which remains without being injected in the valve stem 3 and the large diameter long pipe 5 (small diameter long pipe 6). However, the ratio between the inner diameter D1 of the valve stem 3 and the inner diameter D2 of the large-diameter long pipe 5 (small-diameter long pipe 6) is (1) :( 0.5 Therefore, the progress of the curing of the aerosol contents in the valve stem 3 and the large-diameter long pipe 5 (small-diameter long pipe 6) can be suppressed without causing clogging or the like. Efficient injection can be performed for a long time. At this time, it is preferable to treat the inner surface of these pipes 5 and 6 with a release agent.

As described above, according to the present embodiment, the injection hole 14 of the large-diameter long pipe 5 or the small-diameter long pipe 6 fitted to the pipe fitting portion 9 of the button 4 is used for harmful animals (including pests). ), And the lever portion 11 is pulled so as to be close to the aerosol container 2, whereby the aerosol contents can be intensively jetted around the entrance / exit, that is, at a desired location. it can.
At this time, if the large-diameter long pipe 5 is used, an injection amount corresponding to the opening area can be obtained for a relatively large entrance / exit. On the other hand, if the small-diameter long pipe 6 is used, an injection amount corresponding to the opening area can be obtained for a relatively small entrance / exit.
In addition, since the lever portion 11 extends to the side of the aerosol container 2 and is formed so as to fully open the valve stem 3 at the time of use, the valve stem 3 is sufficiently operated with a smaller force corresponding to its length. Therefore, a desired injection amount can be obtained with certainty. For this reason, efficient injection can be performed.

  Furthermore, the ratio of the inner diameter dimension D1 of the valve stem 3 to the inner diameter dimensions D2 and D3 of the large diameter long pipe 5 and the small diameter long pipe 6 is as follows. Since the dimensions D2 and D3 are set to be 0.5 or more, the progress of curing of the aerosol contents in the valve stem 3 and the long pipes 5 and 6 can be suppressed, and clogging and the like can be prevented. Efficient injection can be performed for a long time without occurring.

  In addition, according to the present embodiment, the tip of the lever portion 11 is provided so as to be obliquely above the end of the aerosol container 2 in a state where the valve stem 3 of the aerosol container 2 is directed downward. Therefore, the user can operate the lever portion 11 while holding the aerosol container 2. For this reason, efficient injection can be performed and usability can be improved.

  Moreover, according to this embodiment, the aerosol content is a foamed polyurethane aerosol composition containing a harmful animal repellent, a urethane prepolymer, and a propellant, and the injection ports 14 of the long pipes 5 and 6 are provided. By moving the lever portion 11 toward the aerosol container 2 after approaching the entrance allowing the entry of harmful animals, a rigid polyurethane foam containing a harmful animal repellent is provided around the entrance allowing the entry of harmful animals. The body adheres and hardens and closes the doorway.

In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimension, numerical value, form, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
For example, the mountain cap 16 of the aerosol spray device 1 may be used to cover and seal the cap.
