Description

本発明は、内容物を液化ガスで噴出させるエアゾール容器に関し、詳しくは、使用済みのエアゾール容器に残留するガスを容易に排出することのできる排出機構付きエアゾール容器に関する。   The present invention relates to an aerosol container that ejects contents with a liquefied gas, and more particularly, to an aerosol container with a discharge mechanism that can easily discharge gas remaining in a used aerosol container.

使用済みエアゾール容器には、使用によって放出しきれなかった液化ガスが残留しており、使用済みエアゾール容器がそのまま廃棄されると、廃棄された環境よっては破裂したり、火中に投じられると爆発するおそれがあった。従って、消費者が廃棄する際に残留ガスを完全に放出しておくことが望まれている。   Liquefied gas that could not be released due to use remains in the used aerosol container, and if the used aerosol container is discarded as it is, it may explode depending on the discarded environment or explode if thrown into fire. There was a risk. Therefore, it is desired that the residual gas be completely discharged when the consumer discards.

消費者が押しボタンを押し続けて残留ガスを完全に放出する手段は、作業時間と労力がかかり過ぎるうえに、ガス抜きが不完全に終わり易いことから、消費者が確実にガス抜きをするには、金槌やポンチ等の器具を使って使用済みエアゾール容器に孔を開ける必要がある。   The means by which the consumer continues to push the push button to completely release the residual gas is too time consuming and labor intensive, and the degassing tends to be incomplete. Need to make a hole in the used aerosol container with tools such as hammers and punches.

しかしながら、この残留ガス抜き手段は、作業性が悪いうえに、放出ガスとともに容器内に付着している残留内容物の噴出により、周辺や衣服を汚染してしまう虞があり、作業が面倒であるのでガス抜きを行わないで廃棄されてしまうことが多い。   However, this residual gas venting means is not only workable, but also the surroundings and clothes may be contaminated by the ejection of the residual contents adhering to the inside of the container together with the released gas, and the work is troublesome. Therefore, it is often discarded without venting.

このような問題に対応して、消費者が使用済みエアゾール容器の押しボタンを簡単に継続噴射状態にできれば、消費者の手で確実に残留ガスを抜くことができるので、使用済みエアゾール容器を廃棄する際に、消費者が簡単に継続噴射状態に操作できる残留ガス抜き機構を備えたものが多数提案されている。   Responding to such problems, if the consumer can easily put the push button on the used aerosol container into the continuous injection state, the residual gas can be surely removed by the consumer, so the used aerosol container is discarded. In doing so, many devices have been proposed that include a residual gas venting mechanism that allows a consumer to easily operate in a continuous injection state.

例えば、特開２００２−６８３３９号公報や、特開２００２−２５５２６６号公報には、押しボタンとカバー体の部分に相互に係合する係合手段を形設し、押しボタンの押し下げ時に、押しボタンとカバー体をそれぞれの係合手段によって係合させることにより継続噴射を可能とした残留ガス抜き機構を備えたエアゾール容器が開示されている。   For example, in Japanese Patent Application Laid-Open No. 2002-68339 and Japanese Patent Application Laid-Open No. 2002-255266, an engaging means that engages with the push button and the cover body is formed, and the push button is pressed when the push button is depressed. An aerosol container having a residual gas venting mechanism that enables continuous injection by engaging a cover body with a cover body by respective engaging means is disclosed.

これらの物は、消費者が、廃棄する前に押しボタンを押し下げて、押しボタンとカバー体を係合しておけば、押しボタンを押し続けなくても残留ガスが放出されるので、煩わしいガス抜き作業をすることなく使用済みエアゾール容器のガスを完全に抜き去ることが出来るものである。
特開２００２−６８３３９号公報 特開２００２−２５５２６６号公報 These items are annoying gas because if the consumer pushes down the push button before disposing and engages the push button and the cover body, the residual gas is released without continuing to push the push button. It is possible to completely remove the gas from the used aerosol container without performing the extraction operation.
JP 2002-68339 A JP 2002-255266 A

押しボタンに設けた係合手段とカバー体に設けた係合手段とを係合させて、ガスの放出を継続させることにより残留ガス抜きをする従来公知のガス抜き機構は、押し下げた押しボタンとカバー体とが係合すると、簡単には係合状態が解除できない構成となっており、廃棄後も噴射状態が確実に継続する。   A conventionally known gas venting mechanism for releasing residual gas by engaging the engaging means provided on the push button and the engaging means provided on the cover body and continuing the release of gas includes a push button pressed down When the cover body is engaged, the engagement state cannot be easily released, and the injection state continues reliably even after disposal.

しかしながら、係合手段を作動させるガス抜き機構によって残留ガスを完全に排出するには、それなりの放出時間を要するので、消費者がガス抜き作業中に用事が発生してガス抜き作業を中断しなければならない事態も想定されるが、従来公知の残留ガス抜き機構は、この点についての配慮が全くなされておらず、作業者は排出が終了する迄見守るか、継続噴射中のものを完了を待たずして廃棄しなければならなかった。   However, since it takes a certain amount of time to completely discharge the residual gas by the degassing mechanism that operates the engaging means, the consumer must interrupt the degassing operation due to the occurrence of errands during the degassing operation. However, the conventional residual gas venting mechanism does not take this point into consideration at all, and the operator watches until the discharge ends or waits for completion of the continuous injection. It had to be discarded.

本発明は、上記の問題に鑑みてなされたもので、残留ガスの排出が容易にできるとともに、ガス抜き作業の中途でも、速やかにガス抜き作動を解除できる機能を有する残留ガス抜き機構付きエアゾール容器にすることを課題にしている。   The present invention has been made in view of the above-described problem, and is an aerosol container with a residual gas venting mechanism that can easily discharge residual gas and can quickly release the gas venting operation even in the middle of the gas venting operation. The challenge is to make it.

本発明は、上記の問題を解決する為に、エアゾール缶の上端をエアゾールバルブで密閉し中央に上下動可能に上方へ付勢された状態のバルブステムが起立する容器本体と、前記容器本体の上端部に嵌着されたカバー体と、前記バルブステムに嵌着されて前記カバー体の内側に上下動可能に配備された押しボタンと、を有してなり、前記カバー体の周壁にスリットを設けることにより、内方に弾性変形可能にして弾性復帰可能な掛止板部を形成し、且つ前記押しボタンの外側に、該押しボタンが継続噴射可能な押し下げ位置において内方に弾性変形させた前記掛止板部と係合可能な上向き突起を形成し、内方に弾性変形させた前記カバー体の掛止板部に前記押しボタンの上向き突起を係合させることにより継続噴射を可能とするとともに、前記押しボタンを更に押圧して下降させることにより、前記掛止板部と押しボタンとの係合が解除されて、継続噴射の中止を可能とした。   In order to solve the above problems, the present invention provides a container body in which an upper end of an aerosol can is sealed with an aerosol valve and a valve stem in a state of being urged upward so as to be vertically movable in the center, A cover body that is fitted to the upper end portion, and a push button that is fitted to the valve stem and arranged to be movable up and down inside the cover body, and has a slit in the peripheral wall of the cover body By providing, a latch plate portion that can be elastically deformed inward and can be elastically restored is formed, and the push button is elastically deformed inward at the push-down position where the push button can be continuously ejected on the outside of the push button. An upward projection that can be engaged with the retaining plate portion is formed, and the upward projection of the push button is engaged with the retaining plate portion of the cover body that is elastically deformed inward, thereby enabling continuous injection. Together with the above By that is further lowered by pressing button, the engagement between the engaging plate portion and the push button is released, to allow discontinuation of continuous injection.

スリットが、カバー体の周壁の周方向へ延びて設けられている構成とすることが好ましい。   The slit is preferably provided so as to extend in the circumferential direction of the peripheral wall of the cover body.

また、掛止板部が、カバー体の周壁上端に開放された縦方向の二条のスリットで形成され、前記掛止板部の上端内側には押しボタンの上向き突起と係合する下向き突起が形成されている構成としてもよい。   Further, the latch plate portion is formed by two vertical slits opened at the upper end of the peripheral wall of the cover body, and a downward projection that engages with the upward projection of the push button is formed inside the upper end of the latch plate portion. It is good also as the structure currently made.

また、前記縦方向の二条のスリットで形成された掛止板部が、カバー体の周壁の中心を挟んで対向して形成されている構成としてもよい。   Moreover, it is good also as a structure which the latching board part formed of the said 2 slits of the vertical direction opposes on both sides of the center of the surrounding wall of a cover body.

本発明の残留ガス排出機構付きエアゾール容器によれば、カバー体の周壁にスリットを設けることにより形成した掛止板部を、内方に弾性変形可能にして且つ弾性復帰可能としたので、従来周知の残留ガス排出機構と同様に、廃棄に際して、残留ガスの継続噴射を可能とするとともに、押しボタンを更に押圧して下降させることにより、掛止板部と押しボタンとの係合が解除されて、残ガス処理の継続噴射を速やかに中止できるようにしたので、作業者がガス抜き作業中に用事が発生してガス抜き作業を中断しなければならない場合でも、ガス抜き作業を速やかに安全に中断して対処することができる。   According to the aerosol container with a residual gas discharge mechanism of the present invention, the latch plate portion formed by providing a slit in the peripheral wall of the cover body can be elastically deformed inward and can be elastically restored. As in the case of the residual gas discharge mechanism, the residual gas can be continuously injected upon disposal, and the push button is further pushed down to release the engagement between the latch plate portion and the push button. Since the continuous injection of the residual gas treatment can be stopped promptly, even if an operator needs to interrupt the degassing operation during the degassing operation, the degassing operation can be performed quickly and safely. Can be interrupted and dealt with.

以下、本発明の残留ガス排出機構付きエアゾール容器の好適な実施の形態を、図面を参照しながら詳細に説明する。   Hereinafter, preferred embodiments of an aerosol container with a residual gas discharge mechanism of the present invention will be described in detail with reference to the drawings.

図１乃至図１０は、本発明の残留ガス排出機構付きエアゾール容器の第一の実施の形態を示しており、図２乃至図３に示すように、この実施の形態の残留ガス排出機構付きエアゾール容器は、エアゾール缶２の上端をエアゾールバルブ３で密閉し中央に上下動可能に上方へ付勢された状態のバルブステム４が起立する容器本体１と、容器本体１の上端部に嵌着されたカバー体１０と、バルブステム４に嵌着されて前記カバー体１０の内側に上下動可能に配備された押しボタン３０と、を有し構成されている。   FIGS. 1 to 10 show a first embodiment of an aerosol container with a residual gas discharge mechanism of the present invention. As shown in FIGS. 2 to 3, the aerosol with a residual gas discharge mechanism of this embodiment is shown in FIGS. The container is fitted to the container main body 1 in which the upper end of the aerosol can 2 is sealed with an aerosol valve 3 and the valve stem 4 is urged upward so as to be movable up and down in the center, and the upper end of the container main body 1 is fitted. The cover body 10 and a push button 30 that is fitted to the valve stem 4 so as to be movable up and down inside the cover body 10.

容器本体１は、噴射用の液化ガスと流動性の内容物が充填されたエアゾール缶２の口部にエアゾールバルブ３をクリンプして密閉して成り、エアゾール缶２の肩部には、カバー体１０の周壁１１下端に設けた内向きの環状突起１２とアンダーカット係合する係合用の周溝５が凹設されている。   The container body 1 is formed by sealing and sealing an aerosol valve 3 at the mouth of an aerosol can 2 filled with a liquefied gas for injection and a fluid content. A circumferential groove 5 for engagement with an inward annular projection 12 provided at the lower end of the peripheral wall 11 is engaged with the undercut.

カバー体１０は、円形の頂壁１３の端縁から周壁１１が垂下形成された略キャップ状を呈し、カバー体の周壁１１の上部には押しボタン３０の噴口３１が覗く窓穴１４が形成されている。また、窓穴１４と直径沿いに対向する周壁１１には、周壁１１から頂壁１３にかけて窓穴１４よりも大きく切り欠いた指挿入用の切欠部１５が形成されている。   The cover body 10 has a substantially cap shape in which the peripheral wall 11 is suspended from the edge of the circular top wall 13, and the window hole 14 through which the nozzle 31 of the push button 30 is viewed is formed in the upper part of the peripheral wall 11 of the cover body. ing. Further, the peripheral wall 11 facing the window hole 14 along the diameter is formed with a notch 15 for inserting a finger that is larger than the window hole 14 from the peripheral wall 11 to the top wall 13.

切欠部１５の下方には、切欠部１５と所定間隔をおいて平行するカバー体１０の周壁１１の周方向へ延びるスリット１６が設けられている。このスリット１６の上部の周壁部は、押圧すれば内方に弾性変形可能にして、押圧を解除すれば弾性復帰可能な掛止板部１７となっている。   A slit 16 extending in the circumferential direction of the peripheral wall 11 of the cover body 10 is provided below the notch 15 and is parallel to the notch 15 at a predetermined interval. The upper peripheral wall portion of the slit 16 is a retaining plate portion 17 that can be elastically deformed inward when pressed and can be elastically restored when the pressure is released.

この係止板部１７は、押しボタン３０の押し下げ時に、掛止板部１７を内方に弾性変形させて、押しボタン３０の係合手段と係合させることにより、押しボタン３０を押し下げ状態に維持して継続噴射を可能とする残留ガス抜き機構を構成している。そして、掛止板部１７の係合状態から更に押しボタン３０を下降させることにより、押しボタン３０と掛止板部１７との係合が外れると、掛止板部１７は弾性的に自己復帰して押しボタン３０をフリーにする。   When the push button 30 is pushed down, the locking plate portion 17 elastically deforms the latch plate portion 17 inward and engages with the engaging means of the push button 30, thereby bringing the push button 30 into a pushed-down state. A residual gas venting mechanism that maintains and enables continuous injection is configured. When the push button 30 is further lowered from the engagement state of the latch plate portion 17 and the engagement between the push button 30 and the latch plate portion 17 is released, the latch plate portion 17 elastically self-resets. Thus, the push button 30 is released.

また、カバー体１０の頂壁１３には、破断可能な複数の連結片１８を介して引き離し可能に保護板１９が一体形成されている。この保護板１９は、窓穴１４側に前側縁１９ａを有し切欠部１５側に円弧の後側縁１９ｂを自由端とした末広がりの舌片状の板部に垂壁１９ｃが垂下形成されたものであり、その平面形状は、保護板１９下面に位置する押しボタン３０の平面形状の大部分とほぼ相似形を呈している。   A protective plate 19 is integrally formed on the top wall 13 of the cover body 10 so as to be separated through a plurality of breakable connecting pieces 18. This protective plate 19 has a hanging wall 19c suspended from a divergent tongue-shaped plate portion having a front edge 19a on the window hole 14 side and a rear edge 19b of the arc on the notch 15 side as a free end. The planar shape thereof is substantially similar to the majority of the planar shape of the push button 30 located on the lower surface of the protection plate 19.

保護板１９は、使用以前に、不用意に押しボタン３０が押されてしまったり、不正使用の防止を目的に設けたものであり、使用するときは、切欠部１５に指を入れ保護板１９を上方に引き上げて連結片１８を破断して引き離す。図４は、押しボタン３０を装着したカバー体１０を示しており、図５乃至図６は、押しボタン３０を装着したカバー体１０の保護板１９を引き離して取り去った状態を示している。   The protection plate 19 is provided for the purpose of preventing the push button 30 from being inadvertently pressed before use or preventing unauthorized use. When using the protection plate 19, a finger is put into the notch 15 and the protection plate 19 is used. Is pulled upward to break and separate the connecting piece 18. 4 shows the cover body 10 to which the push button 30 is attached, and FIGS. 5 to 6 show a state in which the protective plate 19 of the cover body 10 to which the push button 30 is attached is pulled away and removed.

また、カバー体１０における保護板１９の下方は、保護板１９の側縁に沿って頂壁１３から垂下する前板２０と、窓穴１４側を前方として末広がりに対面する二枚の側板２１、２１と、による押しボタン３０が作動可能に収納された押しボタン３０のガイド部となっている。   Further, the lower side of the protective plate 19 in the cover body 10 includes a front plate 20 that hangs down from the top wall 13 along the side edge of the protective plate 19, and two side plates 21 that face the end of the window hole 14 side forward, 21 is a guide portion of the push button 30 in which the push button 30 is operably accommodated.

ガイド部を構成する各側板２１、２１の下端前方には、押しボタン３０の前方に設けた一対の回転軸３２が回動自在に嵌合する一対の軸受孔２２が形成され、各側板２１、２１の後方には、押しボタン３０の後方に設けた一対のガイド突起３３を上下方向に案内する一対のガイド溝２３が切り欠かれている。また、前板２０の下端が押しボタン３０の上面前方に当接していて、押しボタン３０の上方への動きを抑制している。   A pair of bearing holes 22 into which a pair of rotating shafts 32 provided in front of the push button 30 are rotatably fitted are formed in front of the lower ends of the side plates 21 and 21 constituting the guide portion. A pair of guide grooves 23 for guiding a pair of guide protrusions 33 provided on the rear side of the push button 30 in the vertical direction are cut out behind the push button 30. In addition, the lower end of the front plate 20 is in contact with the upper front of the push button 30 to suppress the upward movement of the push button 30.

押しボタン３０は、カバー体１０のガイド部の側板２１にその両側面３４を接して配置されている。押しボタン３０は、その噴口３１側を前方として平面形状が末広がりに形成されており、その上面後方には指掛け凹所３５が形成され、指掛け凹所３５の後端下方には、後方に延びる端縁円弧の円弧板３６が設けられ、円弧板３６の後端縁中央には上向き突起３７が突設されており、この上向き突起３７が残留ガス抜き機構を構成する押しボタン３０側の係合手段となっている。   The push button 30 is disposed in contact with the side plate 21 of the guide portion of the cover body 10 on both side surfaces 34. The push button 30 is formed so that its planar shape is widened with the nozzle hole 31 side in front, a finger hook recess 35 is formed at the rear of the upper surface, and a rear extending end is provided below the finger hook recess 35. An arc plate 36 having an edge arc is provided, and an upward projection 37 projects from the center of the rear edge of the arc plate 36. The upward projection 37 is an engaging means on the push button 30 side constituting the residual gas venting mechanism. It has become.

押しボタン３０には、バルブステム４に嵌合し内容物が通過する縦通路３８と、縦通路３８に直交して連通し先端に噴口３１を有する横通路３９が穿設されている。横通路３９の噴口３１はカバー体１０の窓穴１４を覗く位置にある。押しボタン３０の噴口３１の下方には、カバー体１０の内周壁に弾性的に接する板バネ４０が垂設されている。   The push button 30 is provided with a vertical passage 38 which is fitted to the valve stem 4 and through which the contents pass, and a horizontal passage 39 which is orthogonal to the vertical passage 38 and has a nozzle 31 at the tip. The nozzle hole 31 of the lateral passage 39 is in a position to look into the window hole 14 of the cover body 10. A leaf spring 40 that is elastically in contact with the inner peripheral wall of the cover body 10 is provided below the nozzle hole 31 of the push button 30.

また、押しボタン３０は、その前方に垂設した脚板４１の回転軸３２がガイド部側板２１の軸受孔２２に回動自在に嵌合し、その後方に垂設した脚板４２のガイド突起３３がガイド部側板２１のガイド溝２３に昇降可能に嵌合して作動可能に取り付けられている。   Further, the push button 30 has a rotating shaft 32 of a leg plate 41 suspended in front of the push button 30 rotatably fitted in the bearing hole 22 of the guide portion side plate 21, and a guide projection 33 of a leg plate 42 suspended in the rear thereof. A guide groove 23 of the guide part side plate 21 is fitted so as to be movable up and down so as to be operable.

上記の部材から成るエアゾール容器を組み立てるには、予め押しボタン３０をカバー体１０の下方からガイド部に挿入して組み付けておく。そして、このカバー体１０を容器本体１に被せて治具を使って押圧すれば、カバー体１０の周壁１１下端に設けた内向きの環状突起１２とエアゾール缶２の肩部の周溝５がアンダーカット係合すると共に、押しボタン３０の縦通路３８にバルブステム４が嵌合して簡単に組み立てることができる。   In order to assemble the aerosol container composed of the above members, the push button 30 is inserted into the guide portion from below the cover body 10 and assembled in advance. And if this cover body 10 is covered on the container main body 1 and pressed using a jig, an inward annular projection 12 provided at the lower end of the peripheral wall 11 of the cover body 10 and a circumferential groove 5 on the shoulder portion of the aerosol can 2 are formed. In addition to the undercut engagement, the valve stem 4 can be fitted into the vertical passage 38 of the push button 30 for easy assembly.

図７は、押しボタン３０の指掛け凹所３５を押圧して作動させた噴射状態を示しており、廃棄の為に残留ガスを継続噴射状態に維持するには、図８に示すように、押しボタン３０を押圧したまま、掛止板部１７を押圧して内方に弾性変形させ、押しボタン３０の上向き突起３７を掛止板部１７に係合させればよい。   FIG. 7 shows an injection state in which the finger recess 35 of the push button 30 is pressed and operated. To maintain the residual gas in the continuous injection state for disposal, as shown in FIG. While the button 30 is being pressed, the latching plate portion 17 may be pressed and elastically deformed inward, and the upward projection 37 of the pushbutton 30 may be engaged with the latching plate portion 17.

ガス抜き作業を中断しなければならないときは、掛止板部１７に係合状態の押しボタン３０を押して更に下降させれば、掛止板部１７が自身の弾性反転力で弾性復帰して押しボタン３０との係合状態が解除される。したがって、押しボタン３０はフリーとなり、その押圧を中止すれば、押しボタン３０は、バルブステム４の上昇力と板バネ４０の弾性復帰力により静止位置に寸時に復帰する。このように、押しボタン３０を指を使って押し離すという、指による瞬時のアクションで残留ガスの排出処理作業を中断することができる。   When it is necessary to interrupt the degassing operation, if the push button 30 engaged with the latch plate portion 17 is pushed and further lowered, the latch plate portion 17 is elastically restored by its own elastic reversal force and pushed. The engaged state with the button 30 is released. Accordingly, the push button 30 becomes free, and if the push is stopped, the push button 30 returns to the stationary position in time by the rising force of the valve stem 4 and the elastic return force of the leaf spring 40. In this way, the residual gas discharge processing operation can be interrupted by an instantaneous action of the finger by pressing and releasing the push button 30 with the finger.

図９乃至図１０は、第二の実施の形態を示しており、この容器の基本的形態は先の実施の形態と同様であるので、共通する部分については同一符号を付し、その説明を省略する。   9 to 10 show a second embodiment. Since the basic form of this container is the same as that of the previous embodiment, common portions are denoted by the same reference numerals, and the description thereof is omitted. Omitted.

この容器にあっては、カバー体１０ａの周方向に延びるスリット１６ａによって形成さた掛止板部１７ａは、周壁１１の内側、即ち、内周壁面２４に沿って形成されている。この掛止板部１７ａは、第一の実施の形態における掛止板部１７と同様に、内方に弾性変形可能にして且つ弾性復帰可能に設定されており、作動方法や作用効果も同様である。   In this container, the retaining plate portion 17 a formed by the slit 16 a extending in the circumferential direction of the cover body 10 a is formed along the inner side of the peripheral wall 11, that is, along the inner peripheral wall surface 24. The latch plate portion 17a is set so as to be elastically deformable inward and elastically returnable in the same manner as the latch plate portion 17 in the first embodiment, and has the same operation method and effect. is there.

この実施の形態によれば、合成樹脂製のカバー体１０ａを成形する射出成形用の金型を、複雑な割型構造にすることなくスリット１６ａの形成が可能である。したがって、制作費が安価な構造の経済的な金型を用いて、周壁周方向に延びる掛止板部１７ａが形成されたカバー体１０ａを生産することができる。   According to this embodiment, it is possible to form the slit 16a without making the mold for injection molding for molding the cover body 10a made of synthetic resin into a complicated split mold structure. Therefore, it is possible to produce the cover body 10a in which the retaining plate portion 17a extending in the circumferential wall circumferential direction is formed using an economical mold having a structure with a low production cost.

図１１乃至図１２は、第三の実施の形態を示しており、この実施の形態におけるカバー体１０ｂは、容器本体１ｂのクリンプリム６に嵌着する台部２５の上面に、上端に内向きのフランジ２７を有する周壁１１が立設され、この周壁１１には、周壁上端に開放された縦方向の二条のスリット１６ｂ、１６ｂで形成された掛止板部１７ｂ、１７ｂが周壁１１の中心を挟んで対向して形成され、各掛止板部１７ｂ、１７ｂは、内方に弾性変形可能にして且つ弾性復帰可能に設定されている。また、各掛止板部１７ｂ、１７ｂの上端内側には、押しボタン３０ｂの上向き突起３７と係合可能な下向き突起２６がフランジ２７の下面に縦断面鉤形状に形成されている。   FIG. 11 to FIG. 12 show a third embodiment. The cover body 10b in this embodiment is inwardly facing the upper surface of the base portion 25 fitted to the crimp prim 6 of the container body 1b. A peripheral wall 11 having a flange 27 is erected. On the peripheral wall 11, latch plate portions 17 b and 17 b formed by two vertical slits 16 b and 16 b opened at the upper end of the peripheral wall sandwich the center of the peripheral wall 11. The latching plate portions 17b and 17b are set so as to be elastically deformable inward and to be elastically returnable.

A cover body 10c in this embodiment has an inward flange at the upper end on the upper surface of a base portion 25 that fits into the crimp prim 6 of the container body 1c. The peripheral wall 11 having 27 is erected, and the peripheral wall 11 is formed with a latch plate portion 17c formed by two longitudinal slits 16c, 16c opened at the upper end of the peripheral wall. It is set so that it can be elastically deformed inward and can be elastically restored. Further, a downward projection 26 that can be engaged with the upward projection 37 of the push button 30c is formed on the lower surface of the flange 27 in the shape of a vertical cross section on the inner side of the upper end of the latch plate portion 17c.

本実施の形態における押しボタン３０ｃは、発泡製品やクリーム状製品に適用されるものである。円形の基盤４４の中央下面にバルブステム４に嵌合する縦通路管４５が垂設され、基盤４４の上面の中央寄りに縦通路管４５に連通するノズル４６が立設され、このノズル４６の基部に沿った基盤上に押圧台４７が形成され、この押圧台４７が形成された基盤４４の外縁に沿って上向き突起３７が形成されている。そして、カバー体１０ｃの開口部に位置するこの押しボタン３０ｃは、その上向き突起３７をカバー体の掛止板部１７ｃの側に位置させて、掛止板部１７ｃと直径に沿い対向するカバー体の周壁１１のフランジ２７と連結ヒンジ４８を介して一体に連結成形されている。   The push button 30c in the present embodiment is applied to foam products and cream products. A vertical passage pipe 45 fitted to the valve stem 4 is suspended from the center lower surface of the circular base 44, and a nozzle 46 communicating with the vertical passage pipe 45 is erected near the center of the upper surface of the base 44. A pressing base 47 is formed on the base along the base, and an upward projection 37 is formed along the outer edge of the base 44 on which the pressing base 47 is formed. And this push button 30c located in the opening part of the cover body 10c makes the upward protrusion 37 located in the side of the latching board part 17c of a cover body, and the cover body which opposes the latching board part 17c along a diameter. The peripheral wall 11 is integrally formed through a flange 27 and a connecting hinge 48.

廃棄の為に残留ガスを継続噴射状態に維持するときは、押しボタン３０ｃの押圧台４７を押圧したまま、掛止板部１７ｃを指で押して内方に弾性変形させ、押しボタン３０ｃの上向き突起３７に掛止板部１７ｃの下向き突起２６を係合させればよい。   When the residual gas is maintained in the continuous injection state for disposal, while the pressing base 47 of the push button 30c is pressed, the retaining plate portion 17c is pushed with a finger to be elastically deformed inward, and the upward protrusion of the push button 30c. What is necessary is just to engage the downward protrusion 26 of the latching plate part 17c with 37.

ガス抜き作業を中断するときは、既述した実施の形態と同様に、係合状態の押しボタン３０ｃの押圧台４７を押して更に下降させれば、掛止板部１７ｃが自身の弾性反転力で弾性復帰して、押しボタン３０ｃとの掛止板部１７ｃとの係合状態が解除され、フリーとなった押しボタン３０ｃによる噴射を直ちに停止することができる。   When the gas venting operation is interrupted, as in the above-described embodiment, if the pressing base 47 of the push button 30c in the engaged state is pressed and further lowered, the retaining plate portion 17c is caused by its own elastic reversal force. The elastic state is restored, the engagement state of the push button 30c with the latch plate portion 17c is released, and the injection by the push button 30c that has become free can be stopped immediately.
