Description

【０００１】
【発明の属する技術分野】
この発明は遅延噴射手段を有するエアゾル噴射器に関する。
【０００２】
【従来の技術】
害虫を駆除するための薬液の噴射などにエアゾル噴射器が通常用いられているが、エアゾル噴射器の使用に際しては押しボタンを押すと同時に薬液が噴射されてしまう。又連続して噴射するためには押しボタンの係止手段が必要である。
ところが例えば強い薬液を大量に連続して噴射したい場合、押しボタンをセットした後、薬液を吸い込んだり、又体に付着したりすれば有害であり、押しボタンのセット後すぐに退避しなければならないという不都合を免れなかった。
【０００３】
【課題を解決するための手段】
この発明は前記の欠点を解消するために、エアゾル容器の上部の噴射装置中にクエン酸水溶液等の有機酸又は無機酸又はそれぞれの水溶液を収納した袋を介挿し、又別に予め重曹等の炭酸水素塩又は炭酸塩を用意し、押しボタンを押し下げたとき、クエン酸水溶液の袋を突き破り、クエン酸等の有機酸又は無機酸と、重曹等の炭酸水素塩又は炭酸塩とを反応させてＣＯ2 を発生させ、その圧力で押しボタンを押し下げた時から所定時間後に噴射が開始されるような遅延噴射手段を有するエアゾル噴射器を得たものである。
【０００４】
【実施例】
図１、図２はこの発明の第１実施例の側断面図であって、図１のＸ−Ｘ線の左半分は使用前の状態、右半分は押しボタンを押し下げた状態を夫々示している。図において、１はエアゾル缶、２はマウント、３はマウント２に固定した肩カバー、５は缶から突き出しているノズルステム、２０は押しボタン兼用噴射ノズル体、２１はその頂板、２２は頂板下面に設けた刺突部、２３はノズル、２４は内部に液通路２５を有する中央脚体、２６は押し下げたとき肩カバー先端４と係合して噴射ノズル体２０を押し下げた位置に係止する係止部である。
３０は噴射ノズル体２０と組み合わされた噴射ノズル補助体、３１は中央筒体、３２は中央空所、３３は液通路、３４はノズルステム嵌装部であって、ノズルステム５に嵌装されている。６は作動中に噴射ノズル補助体３０が下降しないように挿入されているストッパである。そして図示の如く噴射ノズル体２０と噴射ノズル補助体３０との間にクエン酸水溶液等の有機酸又は無機酸又はそれぞれの水溶液を収納した袋７を介挿する。又噴射ノズル補助体３０の中央筒体３１の外側の空間に重曹等の炭酸水素塩又は炭酸塩８を入れておく。３８，３９は噴射ノズル体２０と噴射ノズル補助体３０の間に介在するＯリングである。
【０００５】
図１のＸ−Ｘ線の左半分に示される使用前の状態から頂板２１を指で押して押しボタン兼用噴射ノズル体２０を押し下げてＸ−Ｘ線の右半分の状態とする。そのとき、噴射ノズル補助体３０も下がらないようにストッパ６を入れておく。噴射ノズル体２０の押し下げにより、その頂板２１の下面の刺突部２２により袋７を突き破り、クエン酸等と重曹等とを混合させる。
図２のＹ−Ｙ線の左半分は、図１の右半分と同じ図であり、右半分はクエン酸等と重曹等の反応により発生したＣＯ2 の圧力によって噴射ノズル補助体３０を押し下げた状態を示している。噴射ノズル体２０を押し下げたところでストッパ６は抜いておく。図２の左半分（図１の右半分と同様の状態）の状態ではクエン酸等と重曹等との反応によりＣＯ2 ３５が発生し、その圧力で噴射ノズル補助体３０を押し下げ、それによってノズルステム５を押し下げエアゾル缶内の薬液を噴出させ、噴射ノズル補助体の下降によって形成された液通路３７、液通路２５を経てノズル２３から薬液を噴出させる。Ｓはスプレーを、３６は拡がったＣＯ2 を示している。このように押しボタン兼用噴射ノズル体２０を押し下げてからクエン酸等と重曹等の反応によりＣＯ2 を発生させ、その圧力により噴射ノズル補助体３０及びバルブステム５を押し下げて薬液を噴射させるまで所定の時間が経過するので、噴射遅延手段を有す噴射器となるものである。
【０００６】
図３以下は第２実施例を示し、図３は容器の全体図の断面図、図４は噴射機構部分を取り出して示した断面図であって、１はエアゾル容器、２はマウント、３はマウントに固定された肩カバー、４０は肩カバー３にねじこまれたボタン兼用噴射ノズル体、４１はノズル、４２はねじ込部、４３は噴射ノズル体に固定された液通路筒、４４は液通路筒の適当な位置にあけられた横方向の小孔、４５は液通路筒の下方先端の刺突部、４６は缶上面４７に取り付けられた封鎖体、４８は封鎖体４６の上端にあって上記の小孔４４を封鎖している封鎖部、５０は缶１内にある噴射原液、５１は原液５０中にある吸上管、５２は吸上管の下端の開口であって、吸上管５１は図示の如く封鎖体４６の下端部に嵌め込まれている。
【０００７】
７は封鎖体４６の内部に介装されているクエン酸水溶液等の有機酸又は無機酸又はそれぞれの水溶液を封入した袋、８は原液５０中に予め混合又は溶解されている重曹等の炭酸水素塩又は炭酸塩である。
図５はボタン兼用噴射ノズル体４０をねじ込んで下方に下げた状態を示す。液通路筒４３の下方先端の刺突部４５は下降してクエン酸水溶液を封入した袋７を突き破り、内部のクエン酸水溶液等は吸上管５１を通って原液５０中に入り、その中にある重曹等８と反応してＣＯ2 を発生する。図６は原液中にＣＯ2 ３５が発生している状態を示している。ＣＯ2 は上昇して缶１内の空間９に入り、その空間内のＣＯ2 ３６は原液５０を圧し、原液は吸上管５１中を上昇する。図５に示すように、噴射ノズル体４０をねじ込むとそれに固定された液通路筒４３も下降し、小孔４４は封鎖部４８よりも下方に下がり、小孔４４は開放される。それで吸上管５１を上昇した薬液は小孔４４から液通路筒４３の内部を通ってノズル４１から噴射される。図６でＳはスプレーを示している。
【０００８】
図７、図８は、図６の噴射状態から噴射を停止した時の状態を示すもので、噴射を停止したいときは、ボタン兼用噴射ノズル体４０をねじ戻して上昇させれば、封鎖部４８と小孔４４とは再び合致し、液通路を遮断し噴射を停止する。ＣＯ2 は上部空間９にあって原液５０を押しているので、噴射ノズル体４０を再びねじ込めば噴射を再開することができる。
図９、図１０は、図３以下に示す実施例の別の実施態様を示すものである。図３以下に示した実施例のものでは、ＣＯ2 による圧力が少しかかった時から微量の噴射が始まるという不具合があったので、図９、図１０ではそれを改良して一定の圧力に達するまで噴射が始まらないようにしたものである。即ち、図９に示すようにボタン兼用噴射ノズル体４０の内部において、バネ６０で封鎖片６１を押さえるようにしてある。そうすれば、バネ６０の選択により、所定の圧力で封鎖片を押さえているので、ＣＯ2 の圧力がその所定圧力以上になったときバネ６０に抗して封鎖片６１を押し上げて噴射が始まるので最初から充分な噴射を確保することができる。
【０００９】
【発明の効果】
この出願の発明は前記のような構成であって、押ボタン兼用噴射ノズル体を押し下げた後、クエン酸等と重曹等との反応で生ずるＣＯ2 の圧力により所定時間後に遅延して噴射が始まるので、大量の薬液を連続して噴射したいときも、噴射状態にセット後、充分に退避する時間があるので、薬液を吸い込んだり、体に付着したりする危険を除くことができる。

BACKGROUND OF THE INVENTION
The present invention relates to an aerosol injector having delayed injection means.
[0002]
[Prior art]
An aerosol injector is usually used for spraying a chemical solution for exterminating pests. However, when using the aerosol injector, the chemical solution is sprayed at the same time as the push button is pressed. Further, in order to continuously inject, a push button locking means is required.
However, for example, if you want to inject a large amount of strong chemical continuously, it is harmful if you inhale or adhere to the body after setting the push button, and you must evacuate immediately after setting the push button. I could not escape the inconvenience.
[0003]
[Means for Solving the Problems]
In order to eliminate the above-mentioned drawbacks, the present invention inserts a bag containing an organic acid or inorganic acid such as citric acid aqueous solution or each aqueous solution into an injection device at the upper part of the aerosol container, and separately separates carbonic acid such as sodium bicarbonate. When hydrogen salt or carbonate is prepared and the push button is pressed down, the bag of citric acid aqueous solution is broken through, and an organic acid or inorganic acid such as citric acid is reacted with bicarbonate or carbonate such as sodium bicarbonate to react with CO. 2 is obtained, and an aerosol injector having a delay injection means that starts injection after a predetermined time from when the push button is pressed down by the pressure is obtained.

And the bag 7 which accommodated organic acid, inorganic acids, or each aqueous solution, such as a citric acid aqueous solution, is inserted between the injection nozzle body 20 and the injection nozzle auxiliary body 30 like illustration. Further, hydrogen carbonate such as baking soda or carbonate 8 is put in a space outside the central cylinder 31 of the injection nozzle auxiliary body 30. Reference numerals 38 and 39 denote O-rings interposed between the injection nozzle body 20 and the injection nozzle auxiliary body 30.
[0005]
From the state before use shown in the left half of the XX line in FIG. 1, the top plate 21 is pushed with a finger to push down the push-button spray nozzle body 20 to the right half of the XX line. At that time, the stopper 6 is inserted so that the spray nozzle auxiliary body 30 does not fall. By pushing down the spray nozzle body 20, the bag 7 is pierced by the piercing portion 22 on the lower surface of the top plate 21, and citric acid or the like and sodium bicarbonate or the like are mixed.
The left half of the YY line in FIG. 2 is the same as the right half of FIG. 1, and the right half pushed down the injection nozzle auxiliary body 30 by the pressure of CO 2 generated by the reaction of citric acid or the like with sodium bicarbonate. Indicates the state. The stopper 6 is pulled out when the spray nozzle body 20 is pushed down. In the state of the left half of FIG. 2 (the same state as the right half of FIG. 1), CO 2 35 is generated by the reaction of citric acid or the like with baking soda, etc. The stem 5 is pushed down to eject the chemical solution in the aerosol can, and the chemical solution is ejected from the nozzle 23 through the liquid passage 37 and the liquid passage 25 formed by the lowering of the injection nozzle auxiliary body. S indicates spray and 36 indicates expanded CO 2 . In this way, after the push button / jet nozzle body 20 is pushed down, CO 2 is generated by the reaction of citric acid or the like with baking soda, etc., and the pressure is lowered until the spray nozzle auxiliary body 30 and the valve stem 5 are pushed down to inject the chemical liquid. Therefore, the injector has an injection delay means.
[0006]

FIG. 5 shows a state where the button / jet nozzle body 40 is screwed and lowered downward. The piercing portion 45 at the lower end of the liquid passage cylinder 43 descends and breaks through the bag 7 containing the citric acid aqueous solution, and the citric acid aqueous solution and the like enter the stock solution 50 through the suction pipe 51 and enter it. Reacts with certain baking soda 8 to generate CO 2 . FIG. 6 shows a state in which CO 2 35 is generated in the stock solution. CO 2 rises and enters the space 9 in the can 1, CO 2 36 in the space presses the stock solution 50, and the stock solution rises in the suction pipe 51. As shown in FIG. 5, when the injection nozzle body 40 is screwed, the liquid passage cylinder 43 fixed thereto is also lowered, the small hole 44 is lowered below the blocking portion 48, and the small hole 44 is opened. Thus, the chemical liquid that has moved up the suction pipe 51 is ejected from the nozzle 41 through the small hole 44 and through the inside of the liquid passage cylinder 43. In FIG. 6, S indicates a spray.

In the example shown in FIG. 3 and the subsequent figures, there was a problem that a small amount of injection started when a little pressure was applied by CO 2. Therefore, in FIG. 9 and FIG. Until the injection starts. That is, as shown in FIG. 9, the blocking piece 61 is pressed by the spring 60 inside the button / jet nozzle body 40. Then, since the sealing piece is pressed at a predetermined pressure by the selection of the spring 60, when the CO 2 pressure exceeds the predetermined pressure, the sealing piece 61 is pushed up against the spring 60 and injection starts. Therefore, sufficient injection can be secured from the beginning.
[0009]
【The invention's effect】
The invention of this application is configured as described above, and after pushing down the push-button combined injection nozzle body, the injection is delayed after a predetermined time by the pressure of CO 2 generated by the reaction between citric acid and sodium bicarbonate. Therefore, even when it is desired to inject a large amount of chemical liquid continuously, there is sufficient time to retreat after setting in the injection state, thereby eliminating the risk of inhaling the chemical liquid or adhering to the body.
