Description

【０００１】
【発明の属する技術分野】
本願の発明は、容器内に充填した種々の液状物質を霧状にして噴射するためのエアゾール容器、特に、ゴキブリや白蟻、ダニその他の家屋内に侵入した害虫を駆除するために、必要とする時間だけ連続して殺虫剤を自動的に噴霧するのに適したエアゾール容器に関するものである。
【０００２】
【従来の技術】
ゴキブリやノミ、ダニ等の屋内害虫に対する駆除方法として、駆除する害虫に対して殺虫効果のある薬剤を直接あるいは間接的に噴霧する方法が採られており、従来から使用されてきたものとしては、バルサン（商標登録）やアースレット（商標登録）等の名称で広く一般に知られている、殺虫剤を缶詰状をした容器に密封包装した燻烝形式の殺虫剤入り容器が用いられてきた。
これらの殺虫剤入りの容器は密閉状態にした室内等に於いて、該容器の蓋体を開封した後で発煙せしめるか、あるいは、容器の蓋体を開封したものに水を添加して気化反応せしめるかして、発生した殺虫剤の煙で密室内を充満させて燻烝することにより殺虫する方法を採用したものである。
【０００３】
しかし、密閉された室内でこれらを用いるには、気化した煙を人や犬、猫等の動物がある一定量以上を吸引すると生命に危険を伴うので、使用に伴う煙の発生に際しては、室外に避難する等の厳重な注意が必要である。
また、これらの形式の容器では燻烝を途中で中止することは不可能であるので、開封した容器の殺虫剤の成分は最後まで使い切らなくてはならないので、害虫を駆除すべき空間が小さい場合には無駄になることがあった。
【０００４】
そこで、このような欠点を無くして、害虫の駆除が必要な時に、駆除すべき場所で必要なだけ随時噴霧可能にしたものとして、特開平６−２８４８４６号や特開平８−２６９２４号公報等に見るように、密封容器に殺虫剤と高圧の噴射剤とを封入したスプレー式の殺虫用エアゾール容器がある。
これらは、害虫の駆除には大きな作用を発揮して、充分な防虫効果が持続できると共に、人類に対しては、毒性や環境汚染性等の面での危険性が無くて、人々が直接または間接的に接触しても問題にならず、安全で且つ手軽に使用することができるという点から一般に広く使用されている。
【０００５】
しかし、これらのスプレー式の殺虫用エアゾール容器を用いて害虫を駆除するには、人がエアゾール容器を直接手に持って噴霧操作を行わなければならないので、駆除作業中はスプレーのノズルヘッドを常時押圧しつづけて殺虫剤を噴射しなければならず、例え人体にとって無害だとは言っても、一定時間以上このような殺虫剤の臭いを嗅ぎつづけると、不愉快に感じて気分を悪くする人がでることがある。
【０００６】
そこで、上記したような殺虫方法に代わるものとして、殺虫剤が人体に有害、無害なものに関係なしに人手に頼らずに連続して噴射可能で、且つ、噴射中であっても途中で、殺虫剤の噴射を自由に停止することが可能である殺虫剤入りの噴霧容器が求められるようになり、その一例として特開平７−２２８５０３号公報に見るような、手動式の開閉バルブを備えた耐圧ボンベ型をした殺虫剤入りの噴霧容器が開発されている。
【０００７】
上記殺虫剤入りの噴霧容器は、図５に示すように、高圧ガス用のボンベの形に類似した耐圧容器の本体２１と、該耐圧容器の内部と外部とを連通させるように容器本体の口部に装着した注出用の内管２２と、該内管の外側に空間ｐを設けて内管を覆うように接合した外管２３とから構成されていて、前記内管の外側端部には、回転可能なハンドル２４とこれに連結した開閉弁を設けた弁座部分２５に突設した噴射口２６とが設けられると共に、前記内管２２の容器内側部分には、その先端部に開口部２２ａが、また、該先端部よりやや上の部分に内管の内部に通ずる連通孔２２ｂが設けられており、更に、前記外管２３には、前記空間ｐに通ずる連通孔２３ａが設けられてエアゾール容器が構成されたものである。
【０００８】
上記のような構成にしたエアゾール容器は、前記ハンドル２４を操作して開閉弁を開いた状態にしてから内部に必要とする殺虫剤等ｆを注入した後、加圧噴射剤となる液化した炭酸ガスやフロンガス、石油ガス等ｇを充填してから開閉弁を閉じて殺虫剤等の噴霧が可能なエアゾール製品となす。
このよう構成にした殺虫剤等の噴霧容器は、殺虫駆除を必要とする場所に運ばれた後、該容器を適正に設置してからハンドル４を捻じって弁を開くと、噴射剤の圧力により殺虫剤は噴射口から連続して噴霧することができて、また、弁が閉じる方向へハンドルを捻じることにより何時でも噴霧を中止することができる。
【０００９】
上記のような殺虫剤等のエアゾール式噴霧容器は、連続噴霧と噴霧の中止が自由に選択可能にしたものではあり、また、内容液の詰め替えも可能であるが、しかし、その反面で容器の製造コストが高くつき、また、容器本体の形状を片手で持てる程度の小型に成形するのが困難であり、やや大きくて重いものにならざるを得ないので、大きなビル等に適用する大容量の噴霧容器には適しているが、一般家庭向け等の小容量の噴霧容器としては不向きである。
【００１０】
【発明が解決しようとする課題】
本願の発明は、上記したような種々の問題を解決して、殺虫剤や防臭剤、あるいは芳香剤等の液状物質を耐圧性の密閉容器内に充填したエアゾール容器に於いて、前記液状物質を霧状に連続して自動的に噴霧することができるようにすると共に、必要に応じて液状物質の噴霧を中断することができるようにして、且つ、該容器の不正開封を防止することができるようにした、小型で軽量なエアゾール容器を安価に提供することを目的とするものである。
【００１１】
【課題を解決するための手段】
本願の発明は、耐圧性の密封容器内に液状の噴射物質と噴射用の高圧ガスとを充填すると共に、該密封容器の開口部に設けられた噴射管の噴射ノズル部分を押圧操作することにより噴射管の噴射弁を開いて、前記容器内の容液を噴射せしめるように構成したスプレー式のエアゾール容器に於いて、前記噴射管には、その下端部に噴射弁筺を介して吸引管等の吸引口を設けて、また、該噴射管の上端部には噴射弁を開くように噴射管を押し下げるための押圧操作部材を装着することにより噴射ノズル部を形成して、更に、前記噴射ノズル部には、不用意に噴射管を押し下げるのを防止するための蓋体を被着して、該蓋体を容器本体の係止部に嵌着してエアゾール容器を構成する。
【００１２】
前記押圧操作部材は、お碗状に湾曲した球面部材を重ね合わせた構造に形成して、前記下側球面部材には、その底部中央に噴射管と嵌合する開口部を設けると共に内部表面上に凹溝を設けて、上側球面部材との間に噴射通路を形成し、また、上側球面部材が下側球面部材の周縁部に連結される部分には環状溝を設けると共に該環状溝に連通する噴射口を上側球面部材の縁部に適当な数だけ設けて噴射ノズル部を形成して、更に、前記下側球面部材の外周縁部に、環状の平坦な押圧作動面を設けると共に、前記押圧作動面の外周端から支持枠体の筒状支持部に係合する円筒部を垂設したものを、エアゾール容器本体に設けた支持枠体の円筒支持部に係合せしめて、前記押圧作動面を押圧することにより噴射管を下方へ押し下げることにより、前記噴射管が噴射状態に保持されるようにした押圧操作部材を構成する。
【００１３】
【作用】
本願の発明は、耐圧性の密封容器本体２の開口部３に設けた噴射管４と該噴射管を押し下げる押圧操作部材５とを設けて噴射ヘッド部を形成してなるスプレー式の液体注出容器に於いて、噴射ヘッド部を形成する押圧操作部材５を取り除いた状態にして、前記密封容器内に液状の噴射物質を充填すると共に、容器内を高圧状態に保つ噴射剤を充填した後、下部押圧部材６の球面部６ａの底部中央に設けた開口部６ｅが前記噴射管４の先端に嵌合するように前記押圧操作部材５を被着せしめると共に、前記下部押圧部材６の係合円筒部６ｃが支持枠体８の筒状支持部８ａに係止するように係合して、前記押圧操作部材５の押圧作用により噴射管４が押し下げられて、噴射状態の位置に保持できるようにしたエアゾール容器１を構成する。
【００１４】
このようにして構成されたエアゾール容器１に対して、前記噴射ヘッド部が不用意に押し下げられるのを防止する円筒状の蓋体９を、前記押圧操作部材５に被着せしめると共に、該押圧操作部材を係止して容器本体に嵌合、保持された筒状の支持枠体８に嵌合、固定せしめて、エアゾール容器の噴射ヘッド部を保護すると共に、不用意に内容液が噴射するのを防止するようにして包装製品となす。
【００１５】
このように構成されたエアゾール容器１を使用するには、包装を解いてから蓋体９を取り除いた後、前記押圧操作部材５を押し下げると、前記支持枠体８の筒状支持部８ａに係合されていた下部押圧部材６の円筒部６ｃの先端が、支持枠体の係止部を越えて押し下げられて、円筒部の先端の係止突部が支持枠体の係止部の下に固定されて、噴射管４はその先端を押し下げられて噴射状態に保持されるので、容器内の内容液は噴射剤の圧力により勢い良く噴射される。
【００１６】
【実施例】
以下に、本願発明について、最適な一つの実施例に基づいて、図面を参照しつつ詳細に説明する。
本願の発明は、図１に示すように、耐圧性密封容器の開口部３に、噴射管４を上下方向に摺動可能に保持するように突設した開口筒状体３ａを巻き締めて固定してエアゾール容器本体２を形成すると共に、該容器本体の肩部２ａに、押圧操作部材５からなる噴射ヘッド部を係合、保持するための円筒状の支持枠体８を嵌合、固定する突起を形成して、該支持枠体８に、前記噴射管４を押し下げるための押圧操作部材５を押圧可能に係止すると共に、前記押圧操作部材を保護する蓋体９を嵌着して、エアゾール容器１を構成したものである。
【００１７】
前記押圧操作部材５は、図２及び４に示されるように、お碗状をした半球面部６ａの周縁部に環状の平坦な押圧作動面６ｂと係合筒状部６ｃとを連接した押圧部下面部材６と、該押圧部下面部材の半球面部６ａに重畳されると共に、該半球面部の突出縁部６ｄに嵌合、固定するように形成した半球面状をした押圧部上面部材７とから構成されていて、前記噴射管４に前記押圧操作部材５を押圧可能に嵌合して噴射ヘッド部を形成する。
【００１８】
このような噴射ヘッド部は、具体的には図１及び２に示すように、上記押圧部の下部押圧部材６は、お碗状をした球面部６ａの底面中央部には、容器本体２に設けられた噴射管４に押圧可能に嵌合する開口部６ｅが設けられると共に、前記球面部には噴射路となる凹状溝６ｆを設けられてなる半球面状をした部材からなり、更に、該半球面状部の突出した縁部６ｄの外側の外周面に、環状の平坦な押圧作動面６ｂを形成すると共に、該押圧作動面の外周端部に筒状側壁６ｃを垂設して、容器本体２に嵌合した支持枠体８の筒状支持部８ａに係合するように係止部が形成されている。
【００１９】
同様に、前記押圧部上面部材７は、前記押圧部下面部材６の球面部６ａの内周面に合致するように形成した半球面状部材７ａの周縁部に、前記下面部材の半球面部の突出した周縁６ｄに嵌合する嵌合部７ｂを設けると共に、該嵌合部には前記凹状溝６ｆ端部に連通した環状の噴射路７ｃと該噴射路に連通する噴射孔７ｄを設けて形成されている。
【００２０】
上記のように形成された押圧上面部材７の半球面状部材７ａを押圧下面部材６の球面部６ａに重畳すると共に、該下面部材６の球面部６ａの突出した縁部６ｄに前記上面部材７の嵌合部７ｂを嵌合せしめて、図３に見るように一体化すると、両球面部の間には容器本体の噴射管４の開口端から前記噴射孔７ｄに連通する噴射溝６ｆからなる噴射炉が形成されて押圧操作部材５が構成される。
【００２１】
一方、エアゾール容器本体２の開口部に嵌合、固定されて、押圧操作部材５を係合して支持する支持枠体８は、図１及び図４に示すような構造をした円筒体で構成されている。
即ち、容器本体２の肩部に設けられた環状の係合突部２ａに嵌合する嵌合筒部８ｃと、それに連続した蓋体嵌合筒部８ｂと押圧操作部材５が係止する係合筒部８ａとが段状に形成された外側円筒体８１と、該外側円筒体の内側に、容器本体２の開口部３の巻き締め部３ｂに嵌合する嵌合溝８ｄを設けた内側円筒体８２を外側円筒体の係合筒部８ａの内面に連結して形成されて、概略段状をした二重の円筒体に構成されている。
そして、前記外側円筒体８１の係合筒部８ａには、押圧下面部材６の係合筒状体６ｃの先端部に形成された係合凸部を係止する係合凹部が形成されている。
【００２２】
このような構造にした支持枠体８を嵌合、固定してなるエアゾール容器本体２に、前記したように構成した押圧操作部材５を嵌着するには、該押圧操作部材５の下部押圧部材６の球面部６ａの底部中央の開口部６ｅを前記容器本体２の噴射管４に合わせて押し下げると、該下部押圧部材６の係合筒状体６ｃが前記支持枠体８の円筒支持部８ａに係合せしめることができる。
そして、前記押圧操作部材５の係合筒状体６ｃの先端部に形成された係合凸部が円筒支持部８ａの係合凹部に係止されて、エアゾール容器１の噴射ヘッド部が形成される。
【００２３】
上記のようにして噴射ヘッド部を形成した押圧操作部材５は、エアゾール容器１の開口筒状体３ｂから突出した噴射管４を保護すると共に、使用する際に前記噴射管を押し下げる作用と、噴射ヘッドのノズルを噴射状態に保つ作用を兼ねたものである。
【００２４】
そこで、液状の噴射物質が充填されたエアゾール容器１を噴霧させて使用するに際しては、包装された容器の外装紙等を取り除いてから噴射ヘッド部を覆っている蓋体９を外して、該エアゾール容器１を殺虫駆除等を行う場所の適当なところに置いてから、押圧操作部材５の押圧作動面６ｂに指先を押し当てた状態で下方へ強く押し込むと、押圧操作部材５の球面部６ａの底部が噴射管４を押し下げながら、その係合筒状体６ｃの先端の係合凸部は円筒支持部８ａの係合凹部を乗り越えた所で停止する。
【００２５】
このようにして、押圧操作部材５で噴射管４が押し下げられると、容器内の噴射物質は噴射管４の開口部から勢い良く吹き出されて、押圧操作部材５内の噴射溝６ｆを通って噴射路７ｃへと導かれた後、噴射ヘッド部の噴射孔７ｄから外気中に噴霧されるが、前記係合筒状体６ｃの先端の係合凸部が円筒支持部８ａの係合凹部下に係止して、押圧操作部材５は押し下げられた位置に停止したままであるから、噴射物質は噴射孔７ｄから連続して噴霧される状態に保たれる。
【００２６】
従って、本願発明に於いては、上記のようにして押圧操作部材５を押し下げられると、内容液が霧状になって勢い良く噴射されるので、エアゾール容器１から手を離して素早く退避しなければならない。
しかし、本願発明の押圧操作部材５から手を離して安全な場所に退避しても、押圧操作部材５が噴射管４を押し下げたままの位置で保持されているので、元の位置に戻ることもなくて、そのままの状態で噴霧を続けさせることができる。
【００２７】
そして、殺虫駆除や消毒等を行う場所や条件によっては、人が立ち入って作業することが困難な所もあるが、そのような場合でも、本願の発明ような構成をしたエアゾール容器１を用いれば、押圧操作部材５を押し下げたままにして投げ込むことにより殺虫駆除等を行うことが可能である。
また、場合によっては、途中で噴霧を中止したい場合もあるが、そのような時には、押圧操作部材５を上方へ強く押し上げて後退させることにより、噴射管４が元の位置に復帰するので、内容液の噴霧を途中で停止させることができて、エアゾール容器に収容されている溶液を無駄に噴霧させる必要が無い。
【００２８】
以上、説明したように、本願の発明は、エアゾール容器に於ける噴射ヘッド部を、容器の開口部に摺動可能に設けた噴射管と該噴射管を押圧する別体の押圧操作部材とから噴射ヘッド部を構成すると共に、該押圧操作部材を容器本体に設けた支持枠体８に押圧進退が可能な係合構造にして、前記支持枠体に蓋体を嵌合せしめてエアゾール容器としたので、殺虫剤等による燻烝に限らず、色々な香料やハーブ等の精神安定作用を有する芳香剤あるいは消臭材等を必要な時間連続して噴射が可能であり、また、内容物質を必要な量だけ噴射したところで停止することも可能である。
【００２９】
【発明の効果】
本願発明のエアゾール容器は、内容液を自動的に連続して噴射することができると同時に、必要に応じて随時噴射を中止することができるので、内容液を必要以上に無駄に使い捨てすることがない。
また、人が立ち入ることが困難な場所でも使用することができるので、毒性の強い殺虫剤を用いた噴霧あるいは燻烝するのに適している。

BACKGROUND OF THE INVENTION
The invention of the present application requires an aerosol container for spraying various liquid substances filled in the container in the form of a mist, particularly for controlling cockroaches, white ants, mites and other pests that have entered the house. The present invention relates to an aerosol container suitable for automatically spraying insecticides continuously over time.
[0002]
[Prior art]
As a method for combating indoor pests such as cockroaches, fleas, ticks, etc., a method of directly or indirectly spraying a pesticide with an insecticidal effect on the pests to be exterminated has been adopted. A jar-shaped insecticide-containing container in which an insecticide is hermetically packaged in a canned container, which is widely known under the names of Balsan (registered trademark) and Earthlet (registered trademark), has been used.
These pesticide-containing containers can be smoked after opening the lid of the container in a sealed room or the like, or by adding water to the container with the lid of the container opened, a vaporization reaction In other words, a method of killing insects by filling the closed room with smoke of the generated insecticide and trapping it was adopted.
[0003]
However, in order to use these in a sealed room, it is dangerous to inhale the vaporized smoke more than a certain amount of animals such as humans, dogs and cats. Strict caution is required, such as evacuating.
In addition, since it is impossible to stop the sputum in the middle of these types of containers, the insecticide components in the opened container must be used up to the end, so there is little space to remove pests There was a waste.
[0004]
Therefore, Japanese Patent Application Laid-Open No. 6-284846 and Japanese Patent Application Laid-Open No. 8-26924 disclose that such defects are eliminated and spraying can be performed as necessary at a place to be controlled when pest control is required. As can be seen, there is a spray-type insecticide aerosol container in which an insecticide and a high-pressure propellant are sealed in a sealed container.
These have a great effect on pest control and can maintain a sufficient insect control effect, and for human beings, there is no danger in terms of toxicity, environmental pollution, etc. Indirect contact is not a problem and is generally widely used because it can be used safely and easily.
[0005]
However, in order to control pests using these spray-type insecticide aerosol containers, a person must hold the aerosol container directly in his / her hand to perform the spraying operation. If you keep pressing and spraying insecticides, even if it is harmless to the human body, if you keep smelling such insecticides for a certain period of time, people who feel unpleasant and feel bad Sometimes
[0006]
Therefore, as an alternative to the insecticidal method as described above, the insecticide can be continuously sprayed without relying on human hands irrespective of harmless or harmless to the human body, and even during the spraying, A spray container containing an insecticide capable of freely stopping the spraying of the insecticide has come to be demanded. As one example, a manual open / close valve as shown in JP-A-7-228503 is provided. Spray containers with insecticides in the form of pressure cylinders have been developed.
[0007]
As shown in FIG. 5, the spray container containing the insecticide includes a pressure vessel main body 21 similar to the shape of a high-pressure gas cylinder and a mouth of the vessel main body so that the inside and outside of the pressure vessel communicate with each other. And an outer pipe 23 joined to cover the inner pipe by providing a space p outside the inner pipe. The outer pipe 23 is attached to the outer end of the inner pipe. Is provided with a rotatable handle 24 and an injection port 26 projecting from a valve seat portion 25 provided with an opening / closing valve connected thereto, and an opening at the tip of the inner tube 22 on the inner side of the container. The portion 22a is provided with a communication hole 22b that communicates with the inside of the inner tube at a position slightly above the tip, and the outer tube 23 is provided with a communication hole 23a that communicates with the space p. This is an aerosol container.
[0008]
The aerosol container having the above-described structure is a liquefied carbonic acid that becomes a pressurized propellant after injecting a necessary insecticide or the like f into the inside after operating the handle 24 to open the on-off valve. After filling with gas, Freon gas, petroleum gas, etc. g, the on-off valve is closed to make an aerosol product that can be sprayed with insecticides.
When the spray container for insecticides and the like having such a structure is transported to a place where insecticide control is required and then the container is properly installed and the handle 4 is twisted to open the valve, the pressure of the propellant Thus, the insecticide can be continuously sprayed from the injection port, and spraying can be stopped at any time by twisting the handle in the direction in which the valve is closed.
[0009]
Aerosol spray containers such as insecticides as described above can be freely selected for continuous spraying and stopping of spraying, and the contents can be refilled. The manufacturing cost is high, and it is difficult to mold the container body into a small size that can be held with one hand, and it must be somewhat large and heavy. Although it is suitable for a spray container, it is not suitable for a small-capacity spray container for general household use.
[0010]
[Problems to be solved by the invention]
The invention of the present application solves the various problems as described above, and in an aerosol container filled with a liquid material such as an insecticide, a deodorant, or a fragrance in a pressure-resistant sealed container, the liquid material is It is possible to spray continuously in a mist state automatically, interrupt the spraying of the liquid substance if necessary, and prevent unauthorized opening of the container.

The pressing operation member 5 having the injection head portion formed as described above protects the injection pipe 4 protruding from the open cylindrical body 3b of the aerosol container 1 and also has an action of pushing down the injection pipe when used, This also serves to keep the nozzle of the head in the jetting state.
[0024]
Therefore, when the aerosol container 1 filled with the liquid propellant is sprayed and used, the cover 9 covering the ejection head portion is removed after removing the outer packaging paper of the packaged container, and the aerosol container 1 is removed. When the container 1 is placed at an appropriate place for insecticidal extermination or the like and then pressed strongly with the fingertip pressed against the pressing operation surface 6b of the pressing operation member 5, the spherical portion 6a of the pressing operation member 5 While the bottom part pushes down the injection pipe 4, the engaging convex part at the tip of the engaging cylindrical body 6c stops at the point where it has passed over the engaging concave part of the cylindrical support part 8a.
[0025]
Thus, when the injection tube 4 is pushed down by the pressing operation member 5, the injection material in the container is blown out from the opening of the injection tube 4 and injected through the injection groove 6 f in the pressing operation member 5. After being guided to the path 7c, the outside is sprayed into the outside air from the ejection hole 7d of the ejection head portion, but the engagement convex portion at the tip of the engagement cylindrical body 6c is below the engagement concave portion of the cylindrical support portion 8a. Since the pressing operation member 5 remains locked at the depressed position, the spray material is kept sprayed from the spray hole 7d continuously.
[0026]
Therefore, in the present invention, when the pressing operation member 5 is pushed down as described above, the content liquid is atomized and jetted vigorously, so the hand must be released quickly from the aerosol container 1. I must.
However, even when the pressing operation member 5 of the present invention is released and retreated to a safe place, the pressing operation member 5 is held in a position where the injection pipe 4 is pressed down, so that it returns to the original position. Without spraying, spraying can be continued as it is.
[0027]
And depending on the place and conditions for insecticidal and disinfecting, there are places where it is difficult for people to enter and work, but even in such a case, if the aerosol container 1 configured as the invention of the present application is used, It is possible to carry out insecticidal extermination or the like by throwing the pressing operation member 5 while pressing it down.
In some cases, it may be desired to stop spraying in the middle. In such a case, the injection tube 4 is returned to its original position by pushing the pressing operation member 5 upward and moving backward. The spraying of the liquid can be stopped halfway, and there is no need to spray the solution contained in the aerosol container wastefully.
[0028]
As described above, the invention of the present application includes an injection tube in which an injection head portion in an aerosol container is slidably provided in an opening of the container, and a separate pressing operation member that presses the injection tube. Since the ejecting head portion is configured, the pressing operation member has an engaging structure capable of pressing and retreating to the support frame body 8 provided in the container body, and the lid body is fitted to the support frame body to form an aerosol container. In addition to sputum caused by insecticides, various fragrances and herbs can be sprayed with fragrances or deodorants that have a tranquilizing action for the required time, and the contents are required. It is also possible to stop when the amount is injected.
[0029]
【The invention's effect】
The aerosol container of the present invention can automatically and continuously inject the content liquid, and at the same time can stop the injection at any time if necessary, so that the content liquid can be discarded more than necessary. Absent.
