Description

本発明は、エアゾール式製品の作動モード設定操作に基づいてそれまでの閉状態から開状態に移行して容器本体の内容物を外部空間域に噴射するためのバルブ作用部（ステム孔部）および、当該バルブ作用部に通じる正倒立使用態様の内容物通路部を少なくとも有する正倒立バルブ機構に関する。 The present invention relates to a valve action part (stem hole part) for injecting the contents of a container main body into an external space region by shifting from a closed state to an open state based on an operation mode setting operation of an aerosol type product. Further, the present invention relates to a forward / reverse valve mechanism having at least a content passage portion of a forward / inverted use mode that communicates with the valve action portion.

· A second moving valve (second valve structure) that is provided in the inflow passage for inversion and falls by its own weight
It is intended for a normal inverted valve mechanism equipped with the above.

なお、本明細書において、
(11)「静止モード」とは操作ボタンがその初期位置（上動位置）に保持されて、バルブ作用部（ステム孔部）が「閉」状態のままで、容器内容物が外部空間に噴射されない状態を示し、
(12)「作動モード」とは操作ボタンが押圧され、バルブ作用部（ステム孔部）が「開」状態となって、本来、容器本体内部と外部空間域とが「正立用流入通路または倒立用流入通路−正倒立共用通路−バルブ作用部」の経路で連通し、容器本体の内容物が外部空間域に噴射される状態を示し、
(13)正倒立バルブ機構の構成要素名称、例えば上方ボール弁，上方弁座，下方ボール弁，下方弁座，上側鞘状部，下側鞘状部材，下側内部空間域，下側孔部，上側筒状部および下側筒状部などの「上」，「下」は、図１〜図３の正立状態での上下を示している。 In this specification,
(11) “Standing mode” means that the operation button is held in its initial position (upward movement position), the valve action part (stem hole part) remains in the “closed” state, and the container contents are injected into the external space. State that is not
(12) “Operation mode” means that the operation button is pressed and the valve action part (stem hole part) is in the “open” state. Communicating through the path of "inverted inflow passage-normal inverted common passage-valve action section", showing the state in which the contents of the container body are injected into the external space area,
(13) Names of components of the upside-down valve mechanism, for example, upper ball valve, upper valve seat, lower ball valve, lower valve seat, upper sheath, lower sheath, lower inner space, lower hole “Upper” and “Lower” of the upper cylindrical portion and the lower cylindrical portion indicate the upper and lower sides in the upright state of FIGS.

正倒立バルブ機構の正立使用状態では、本来、正立用流入通路の第１の移動弁（第１の弁構造）が開き、かつ、倒立用流入通路の第２の移動弁（第２の弁構造）が閉じた状態に設定される。 In the erecting use state of the erecting valve mechanism, the first moving valve (first valve structure) of the erecting inflow passage is originally opened, and the second moving valve of the erecting inflow passage (the second moving valve) The valve structure is set to a closed state.

そして、これら弁構造の各開閉作用により、
(21)正立容器本体下側の内容物は、正立用流入通路，（開状態の）第１の弁構造および正倒立共用通路を経て外部空間域に噴射され、
(22)正立容器本体上側のガス（圧縮ガス，液化ガスそれぞれの気相分）は、閉状態の第２の弁構造によって、外部空間域へ流出することが阻止される。 And by each opening and closing action of these valve structures,
(21) The contents on the lower side of the upright container body are injected into the external space through the upright inflow passage, the first valve structure (in an open state) and the upright common passage,
(22) The gas on the upper side of the upright container body (gas phase components of the compressed gas and the liquefied gas) is prevented from flowing out to the external space by the closed second valve structure.

倒立使用状態では、第１，第２の移動弁の開閉状態が正立使用時とは逆になり、倒立容器本体下側の内容物は倒立用流入通路，（開状態の）第２の弁構造および正倒立共用通路を経て外部空間域に噴射される。また、倒立容器本体上側のガスは、閉状態の第１の弁構造によって、正倒立共用通路に移動することが阻止される。 In the inverted use state, the opening and closing states of the first and second movement valves are opposite to those in the upright use, and the contents under the inverted container body are the inflow passage for the inversion, the second valve (in the open state) It is injected into the external space through the structure and the upside-down shared passage. Further, the gas on the upper side of the inverted container main body is prevented from moving to the normal inverted shared passage by the closed first valve structure.

このように上述の第１，第２の移動弁（弁構造）を備えた正倒立バルブ機構の本来の内容物噴射動作が担保されるためには、その一方が開状態に設定され、その他方が閉状態に設定されることが必要である。 Thus, in order to ensure the original content injection operation of the upside-down valve mechanism having the first and second moving valves (valve structures) described above, one of them is set to the open state, and the other Needs to be set to the closed state.

すなわち、第１，第２の移動弁（弁構造）がともに閉じて、正倒立共用通路が、容器本体内容物の正立用流入通路および倒立用流入通路のいずれとも連通しない（＝容器本体内容物が外部空間域に噴射されない）、といった状況が継続しないようにしなければならない。 That is, the first and second movement valves (valve structure) are both closed, and the normal inverted shared passage does not communicate with either the upright inflow passage or the inverted inflow passage of the container main body contents (= the container main body content). It should be ensured that the situation does not continue, such as the object is not injected into the outer space.

本発明は、正立用流入通路および倒立用流入通路のそれぞれに弁構造を設けたタイプの正倒立バルブ機構において、作動モードでの正倒立状態の変更にともない当該弁構造が「双方閉」状態になったことを内容物噴射量の減少によって利用者にいわば示唆するとともに、この示唆に基づく作動モード操作中断という簡単な操作により当該「双方閉」状態を解消する、ようにしたものである。 The present invention relates to a normal inverted valve mechanism of a type in which a valve structure is provided in each of the upright inflow passage and the upright inflow passage. When the normal inverted state is changed in the operation mode, the valve structure is in a “both closed” state. In other words, it is suggested to the user by reducing the content injection amount, and the “both closed” state is eliminated by a simple operation of operation mode operation interruption based on this suggestion.

従来、正倒立使用タイプのバルブ機構において、実質的に、
(31)正立用流入通路［410],[411]および倒立用流入通路[420],[421]と、その下流側の正倒立共用通路[401]とを備え、
(32)正立用流入通路の出力側部分に、自重で落下する第１の移動弁[600]および当該移動弁に対する第１の弁座[700]からなる第１の弁構造を設け、
(33)倒立用流入通路の出力側部分に、自重で落下する第２の移動弁[600]および当該移動弁に対する第２の弁座[700]からなる第２の弁構造を設け、
(34)第１の移動弁が第１の弁座に当接し、かつ、第２の移動弁が第２の弁座に当接する状態が生じるのを阻止するため、第１の移動弁と第２の移動弁との間に、第１の弁座と第２の弁座との間隔よりも長い所定長さのプランジャ[800]を介在させる、
ようにした正倒立バルブ機構がすでに提案されている（特許文献１参照）。 Conventionally, in the valve mechanism of the upside down use type,
(31) Equipped with an upright inflow passage [410], [411] and an upside down inflow passage [420], [421], and a downstream downstream normal upright common passage [401],
(32) A first valve structure comprising a first moving valve [600] dropping by its own weight and a first valve seat [700] for the moving valve is provided at the output side portion of the inflow passage for erecting,
(33) A second valve structure comprising a second moving valve [600] dropping by its own weight and a second valve seat [700] for the moving valve is provided at the output side portion of the inflow passage for inversion,
(34) In order to prevent a situation in which the first moving valve contacts the first valve seat and the second moving valve contacts the second valve seat, A plunger [800] having a predetermined length longer than the distance between the first valve seat and the second valve seat is interposed between the two moving valves,
Such a normal upside-down valve mechanism has already been proposed (see Patent Document 1).

この従来の正倒立使用タイプのバルブ機構の場合、上記(34)で述べたように所定長さのプランジャといった新たな機械要素を準備し、これを第１の移動弁と第２の移動弁との間にいわば離間スペーサとして設けたものである。 In the case of this conventional upside-down type valve mechanism, as described in (34) above, a new mechanical element such as a plunger having a predetermined length is prepared, and this is used as a first moving valve and a second moving valve. In other words, it is provided as a spacing spacer.

この離間スペーサの存在により、第１の移動弁と第２の移動弁との間には、少なくとも当該離間スペーサ（プランジャ）の長さ、すなわち第１の弁座と第２の弁座との間隔よりも大きな長さの隔たりが確保される。 Due to the existence of the separation spacer, at least the length of the separation spacer (plunger) between the first movement valve and the second movement valve, that is, the distance between the first valve seat and the second valve seat. Larger length separation is ensured.

そのため、第１の移動弁が第１の弁座に当接し、かつ、第２の移動弁が第２の弁座に当接して第１，第２の弁構造がともに閉状態に設定される、といったことは機構的に生じえない。 Therefore, the first moving valve is in contact with the first valve seat, and the second moving valve is in contact with the second valve seat so that the first and second valve structures are both set in the closed state. Such a thing cannot occur mechanically.

したがって、自重で落下する上方移動弁のみが対応弁座に当接した閉状態となり、貯蔵容器の内容物は「下方側の内容物流入通路‐開状態の下方弁構造‐正倒立共用通路‐開状態のバルブ作用部」を経て外部に噴射される。 Therefore, only the upward movement valve that falls under its own weight is in a closed state where it abuts the corresponding valve seat, and the contents of the storage container are `` the lower content inflow passage-the open lower valve structure-the upside-down shared passage-the open It is injected to the outside through the “valve action portion”.

実開平６−５４５７６号公報Japanese Utility Model Publication No. 6-54576

このように、上述した従来の正倒立バルブ機構では、正立用流入通路に設けられた第１の移動弁（弁構造）と倒立用流入通路に設けられた第２の移動弁（弁構造）との間に上記所定長さの離間スペーサ（プランジャ）を新たに介在させ、これにより、正立用流入通路の第１の弁構造および倒立用流入通路の弁構造がともに閉状態となることを、機構的に阻止している。すなわち、離間スペーサ（プランジャ）といった新たな構成要素を第１，第２の各移動弁の間に配している。 Thus, in the above-described conventional normal inverted valve mechanism, the first movement valve (valve structure) provided in the upright inflow passage and the second movement valve (valve structure) provided in the inversion inflow passage. The spacing spacer (plunger) having the predetermined length is newly interposed between the first valve structure of the upright inflow passage and the valve structure of the upflow inflow passage. , Is mechanically blocking. That is, a new component such as a separation spacer (plunger) is arranged between the first and second movement valves.

そのため、正倒立バルブ機構を組み立てる際の工程数が増えて組立作業の手間がかかり、さらには部品点数が増えて製品のコストアップにつながるなどの問題点があった。 For this reason, the number of processes for assembling the upside-down valve mechanism is increased, requiring time for assembly work, and the number of parts is increased, leading to an increase in product cost.

本発明は、正倒立バルブ機構の作動モードでの正倒立状態の変更にともない、正立用，倒立用の各流入通路の第１，第２の弁構造（倒立作動用，正立作動用）が「双方閉」状態に設定される上記原因に着目して、正倒立バルブ機構の構成要素数を特に増やすことなしに、当該弁構造の「双方閉」状態を解消するようにしたものである。 According to the present invention, the first and second valve structures of the inflow passages for upright and upside down (for upright operation and upright operation) in accordance with the change of the upside-down state in the operation mode of the upside-down valve mechanism Paying attention to the above-mentioned cause that is set to the “both sides closed” state, the “both sides closed” state of the valve structure is eliminated without particularly increasing the number of components of the normal inverted valve mechanism. .

正立用，倒立用の各流入通路に弁構造を単に設けただけの正倒立バルブ機構、すなわち上記離間スペーサを設けるなどの工夫をしていない正倒立バルブ機構の作動モードのとき、その正倒立を逆にすることにより正立用，倒立用の各流入通路の弁構造が「双方閉」の状態になってしまい、当該閉状態が、仮に正倒立バルブ機構を静止モードに復帰させても継続する本質的な理由は次のとおりである。 When the normal inverted valve mechanism is simply provided with a valve structure in each inflow passage for upright and inverted, that is, when the normal inverted valve mechanism is not devised such as providing the above-mentioned separation spacer, By reversing, the valve structure of each inflow passage for erecting and inverting becomes “both closed”, and the closed state continues even if the erecting valve mechanism is returned to the stationary mode. The essential reasons for doing this are as follows.

すなわち、
(41)例えば初期噴射で、下方移動弁が下方弁座から離間して内容物が外部空間域に正常噴射されているとき、上方移動弁は、容器本体内部の大きなガス圧力を内容物流入通路から下方向に受けるとともに、容器本体内部（大圧力）から外部空間域（低圧力：大気圧）へと流れる内容物噴射通路の途中の正倒立共用通路からは小さなガス圧力を上方向に受けるので、当該上方移動弁は、結果として下方向に強く押されて上方弁座に当接した状態に維持され、
(42)この上方移動弁に作用するガス圧力の大小関係は正倒立逆転後も変化しないので、逆転後の下方移動弁（＝逆転前の上方移動弁）は上方向に強く押されて正倒立逆転後の下方弁座（＝逆転前の上方弁座）に当該したままであり、
(43)また、正倒立逆転後の上方移動弁（＝逆転前の下方移動弁）は、逆転前の上方移動弁と同様のガス圧力を上下方向に受けることにより、逆転後の上方弁座に強く当接した状態に維持され、
(44)このように作動モードでの正倒立逆転にともない上下の各移動弁が対応弁座に当接した形にいわばロックされてしまうと、正倒立バルブ機構の作動モードを解除して静止モードに移行させたとしても当該ロック状態における各移動弁に作用する上下方向圧力の大小関係に変化が生じえない、
からである。 That is,
(41) For example, in the initial injection, when the downward movement valve is separated from the downward valve seat and the contents are normally injected into the external space area, the upward movement valve causes the large gas pressure inside the container body to Because it receives from the inside of the container body (large pressure) to the outside space (low pressure: atmospheric pressure), it receives a small gas pressure from the upside-down shared passage in the middle of the content injection passage. As a result, the upward movement valve is strongly pressed downward and maintained in contact with the upper valve seat,
(42) Since the magnitude relationship between the gas pressures acting on the upward movement valve does not change even after the reverse rotation, the downward movement valve after the reverse rotation (= the upward movement valve before the reverse rotation) is strongly pushed upward and is normally inverted. The lower valve seat after reverse rotation (= upper valve seat before reverse rotation) remains applicable,
(43) In addition, the upward movement valve after forward and reverse rotation (= downward movement valve before reverse rotation) receives the same gas pressure as the upward movement valve before reverse rotation in the vertical direction, so that the upper valve seat after reverse rotation Maintained in strong contact,
(44) In this way, if the upper and lower moving valves are locked in contact with the corresponding valve seats due to forward / reverse rotation in the operation mode, the operation mode of the normal inversion valve mechanism is canceled and the stationary mode Even if it is shifted to, there can be no change in the magnitude relationship of the vertical pressure acting on each moving valve in the locked state,
Because.

そこで本発明では、作動モードにおいて本来「開状態」となる下方弁構造が閉じた「双方閉」状態のときにも容器本体内容物を正倒立共用通路へ流入させるためのバイパス通路を形成し、かつ、この「双方閉」状態で静止モードへ復帰した後も当該バイパス通路からの流入動作が継続して（外部空間域から分離後の）当該正倒立共用通路の圧力を高めることにより、下方弁構造が開状態に移行するようにしている。 Therefore, in the present invention, a bypass passage is formed to allow the contents of the container body to flow into the upside-down shared passage even when the lower valve structure that is originally in the open state in the operation mode is closed. In addition, even after returning to the stationary mode in this “both sides closed” state, the inflow operation from the bypass passage continues (after separation from the external space area), thereby increasing the pressure of the upside-down shared passage, The structure is shifted to the open state.

ここで、利用者は、第１，第２の各弁構造の「双方閉」状態を、内容物噴射量の減少、すなわち当該閉状態へ移行する前の「本来の流入通路＋バイパス通路」経由の大噴射量から、閉状態移行後の「バイパス通路のみ」の小噴射量への変化に応じて認識できる。 Here, the user decreases the content injection amount from the “both closed” state of the first and second valve structures, that is, “original inflow passage + bypass passage” before shifting to the closed state. Can be recognized according to the change from the large injection amount to the small injection amount of “bypass passage only” after the transition to the closed state.

そして利用者が内容物噴射量の減少を認識して作動モードの設定操作を解除すると、バルブ作用部が閉じ、正倒立共用通路には依然としてバイパス通路から内容物が流入し、これに応じて正倒立共用通路の圧力が高まり、概略、「下方移動弁に対する正倒立共用通路からの下方向への圧力＋下方移動弁の自重」が「下方移動弁に対する下方流入通路からの上方向への圧力」以上になると、下方移動弁が落下して下方弁構造の閉状態が解消されて本来の内容物噴射状態に復帰する。 When the user recognizes the decrease in the content injection amount and cancels the operation mode setting operation, the valve action part is closed, and the content still flows from the bypass passage into the normal inverted shared passage. The pressure in the inverted shared passage increases, and roughly, "downward pressure from the forward inverted shared passage with respect to the downward movement valve + own weight of the downward movement valve" is "upward pressure from the downward inflow passage with respect to the downward movement valve" If it becomes above, a downward movement valve will fall, the closed state of a downward valve structure will be canceled, and it will return to the original content injection state.

このようなバイパス通路の設定により、正倒立バルブ機構の構成要素数を増やさずに、正倒立バルブ機構の噴射動作の正常化や利便性の向上化を図ることを目的とする。 An object of the present invention is to normalize the injection operation of the normal inverted valve mechanism and improve convenience without increasing the number of components of the normal inverted valve mechanism by setting the bypass passage.

また、容器本体内部と正倒立共用通路との間のバイパス通路を、周知の変形可能な内容物流入用チューブが取り付けられた正立用流入通路の一部から正倒立共用通路へいたる通路態様のものとして、倒立使用時においてもバイパス通路の入力部ができるだけ倒立容器本体の下側空間に位置して噴射用ガスの流入を阻止する、すなわち倒立容器本体の上側空間に存在している噴射用ガスがこのバイパス通路に流入するのを阻止し、これにより所定圧力に基づく容器本体内容物の効率的噴射の持続化を図ることを目的とする。 In addition, the bypass passage between the container main body and the upside-down shared passage is a passage mode extending from a part of the upright inflow passage to which the well-known deformable contents inflow tube is attached to the upside-down common passage. As a matter of course, the input part of the bypass passage is located in the lower space of the inverted container body as much as possible to prevent the inflow of the injection gas even in the inverted use, that is, the injection gas existing in the upper space of the inverted container body The purpose of this is to prevent the inflow of the contents of the container body based on a predetermined pressure, thereby preventing the inflow of the contents into the bypass passage.

また、正立用流入通路および倒立用流入通路の内容物流入部を正立，倒立それぞれの使用態様における容器本体底部に近い部分に位置するように設定し、これにより容器本体内容物が正立用流入通路，倒立用流入通路に入っていかないで容器本体に残留したままになるのを極力さけて、容器本体内容物の有効利用化を図ることを目的とする。 In addition, the contents inflow portion of the upright inflow passage and the upright inflow passage is set so as to be located near the bottom of the container main body in each of the upright and inverted use modes. The purpose is to effectively use the contents of the container body by avoiding remaining in the container body without entering the inflow path and the inflow path for inversion.

本発明では、作動モードの際に正倒立共用通路が容器本体内部と連通する形にして、第１の弁構造および第２の弁構造の双方閉状態のときにも容器本体内容物の正倒立共用通路への流入動作を確保するための、バイパス通路を形成している。 In the present invention, when the first and second valve structures are both closed, the normal and inverted common passage communicates with the inside of the container body during the operation mode, so that the container body contents are normally inverted. A bypass passage is formed to ensure the inflow operation to the common passage.

すなわち、正倒立共用通路への内容物流入路として、本来の正立用または倒立用の流入通路の他に、第１の弁構造および第２の弁構造に対するバイパス通路を設けている。 That is, a bypass passage for the first valve structure and the second valve structure is provided in addition to the original upright or inverted inflow passage as the content inflow passage to the upright common passage.

したがって、外部空間域への噴射口からは流入通路経由の内容物と、バイパス通路経由の内容物とがいわば加算されて噴射される。なお、流入通路およびバイパス経路それぞれの内容物通過抵抗は、単位時間あたりに噴射口から噴射される流入通路経由の内容物がバイパス通路経由のそれよりも多くなるように設定されている。 Therefore, the contents via the inflow passage and the contents via the bypass passage are added and injected from the injection port to the external space area. The content passage resistance of each of the inflow passage and the bypass passage is set so that the content via the inflow passage injected from the injection port per unit time is larger than that via the bypass passage.

そのため、第１，第２の弁構造が「双方閉」になると噴射口からの内容物噴射量が明示的に少なくなる。 Therefore, when the first and second valve structures are “both closed”, the content injection amount from the injection port is explicitly reduced.

また、作動モード設定操作を解除して正倒立バルブ機構が静止モードに復帰すると、バルブ作用部が閉じて正倒立共用通路が外部空間域から遮断される。 Further, when the operation mode setting operation is canceled and the normal inverted valve mechanism returns to the stationary mode, the valve action part is closed and the normal inverted shared passage is blocked from the external space area.

そして、正倒立共用通路にはバイパス通路経由で容器本体の内容物が流入するので、それに応じて正倒立共用通路の圧力が高まっていき、第１，第２の各移動弁に対する上方向および下方向の圧力がバランスする。これにより、そのときの下方移動弁が自重で落下して、下方の弁構造は「開」状態となる。すなわち本来の下方流入通路（正立用流入通路または倒立用流入通路）が正常に動作する。 And since the contents of the container body flow into the normal inverted shared passage via the bypass passage, the pressure of the normal inverted shared passage increases accordingly, and the upward and downward directions with respect to the first and second moving valves are increased. Directional pressure balances. Thereby, the downward movement valve at that time falls by its own weight, and the lower valve structure becomes the “open” state. That is, the original lower inflow passage (upright inflow passage or inverted inflow passage) operates normally.

このように内容物噴射量の減少により、利用者は第１，第２の各弁構造がそれぞれ閉状態になったことを認識でき、また、利用者の当該認識後の作動モードの設定操作解除にともない当該「双方閉」状態が解消されるので、正倒立バルブ機構の構成要素数を増やすことなしに、その利便性の向上化を図ることができる。 Thus, the user can recognize that each of the first and second valve structures has been closed due to the decrease in the content injection amount, and the user can cancel the operation mode setting operation after the recognition. Accordingly, since the “both closed” state is eliminated, it is possible to improve the convenience without increasing the number of components of the forward / reverse valve mechanism.

また、容器本体内部と正倒立共用通路との間のバイパス通路を、周知の変形可能な内容物流入用チューブが取り付けられた正立用流入通路の一部から正倒立共用通路へいたる通路態様のものとして、倒立使用時においてもバイパス通路の入力部ができるだけ倒立容器本体の下側空間に位置して噴射用ガスの流入を阻止する、すなわち倒立容器本体の上側空間に存在している噴射用ガスがこのバイパス通路に流入するのを阻止しているので、所定圧力に基づく容器本体内容物の効率的噴射の持続化を図ることができる。 In addition, the bypass passage between the container main body and the upside-down shared passage is a passage mode extending from a part of the upright inflow passage to which the well-known deformable contents inflow tube is attached to the upside-down common passage. As a matter of course, the input part of the bypass passage is located in the lower space of the inverted container body as much as possible to prevent the inflow of the injection gas even in the inverted use, that is, the injection gas existing in the upper space of the inverted container body Is prevented from flowing into the bypass passage, so that the efficient injection of the contents of the container main body based on the predetermined pressure can be maintained.

また、正立用流入通路および倒立用流入通路の内容物流入端部を正立，倒立それぞれの使用態様における容器本体底部に近い部分に位置するように設定しているので、最後まで噴射されずに容器本体に残留したままとなる内容物の量を極力少なくして、容器本体内容物の有効利用化を図ることができる。 In addition, the contents inflow end of the upright inflow passage and the upright inflow passage are set so as to be located close to the bottom of the container main body in each of the upright and inverted use modes. In addition, the amount of the contents remaining in the container body can be reduced as much as possible, and the container body contents can be effectively used.

図１乃至図６の正倒立バルブ機構の基本的特徴は、
(71)上記(61)の内容物の正立用流入通路といわば並列になる形で上記(53)のサブルートを設け、
(72)作動モードの途中で正倒立が逆に設定されることによって上方ボール弁８および下方ボール弁９が「双方閉」状態になると、外部空間への内容物放出量が減少する、すなわち上記(51)，(52)の一方のメインルートおよび上記(53)のサブルートの「（Ａ＋Ｃ）または（Ｂ＋Ｃ）」から、サブルートのみの「Ｃ」に減少し、
(73)この内容物放出量の減少を認識した利用者が操作ボタン１の押圧を止めると、「双方閉」状態のボール弁８，９間の小径縦筒状部６ｃは外部空間から遮断され、当該筒状部には上記(53)のサブルートにより容器本体内容物が流入してそこでの内容物圧力が大きくなって、最終的には、下側に位置している当該ボール弁が落下し、上記(51)，(52)の正立または倒立のメインルートが復活する、
ことである。 The basic features of the upside down valve mechanism of FIGS.
(71) The sub route of (53) is provided in parallel with the upright inflow passage of the contents of (61),
(72) When the upper ball valve 8 and the lower ball valve 9 are set to the “both closed” state by setting the upside-down in the middle of the operation mode, the amount of content discharged to the external space decreases, that is, From “(A + C) or (B + C)” of one of the main routes (51) and (52) and the sub-route of (53) above, it is reduced to “C” of only the sub-route,
(73) When the user who recognizes the decrease in the content discharge amount stops pressing the operation button 1, the small-diameter vertical cylindrical portion 6c between the ball valves 8 and 9 in the “both closed” state is blocked from the external space. Then, the contents of the container main body flow into the cylindrical portion by the sub route of (53), and the pressure of the contents there increases, and finally, the ball valve located on the lower side falls. , The upright or inverted main route of (51), (52) above is revived,
That is.

図示の正倒立バルブ機構のさらなる特徴は、
(74)容器本体内部と正倒立共用通路との間のバイパス通路を、ディップチューブ１０の先に続く下側内部空間域７ｂと、正倒立共用通路の始まり部分である小径縦筒状部６ｃとの間に形成して、倒立使用時においてもバイパス通路の入力部ができるだけ倒立容器本体の下側空間に位置して噴射用ガスの流入を阻止する、すなわち倒立容器本体の上側空間に存在している噴射用ガスがこのバイパス通路に流入するのを阻止し、
(75)正立用流入通路の内容物流入部をディップチューブ１０の端部とし、また、倒立用流入通路の内容物流入部をカバー体７の環状低内周面部分７ａの端部とし、すなわち正立，倒立それぞれの使用態様における容器本体底部に近い部分に設定することにより、容器本体内容物が正立用流入通路，倒立用流入通路に入らずに噴射されないままになるのを極力少なくしている、
ことである。 Further features of the illustrated inverted valve mechanism are:
(74) A bypass passage between the inside of the container body and the normal inverted shared passage, a lower internal space area 7b following the tip of the dip tube 10, and a small-diameter vertical cylindrical portion 6c which is a starting portion of the normal inverted shared passage, Even when used upside down, the input part of the bypass passage is located in the lower space of the inverted container body as much as possible to prevent the flow of the injection gas, that is, it exists in the upper space of the inverted container body. Prevent the injection gas from flowing into this bypass passage,
(75) The content inflow portion of the upright inflow passage is the end of the dip tube 10, and the content inflow portion of the inversion inflow passage is the end of the annular low inner peripheral surface portion 7a of the cover body 7, that is, By setting the part close to the bottom of the container body in each of the standing and inverted usage modes, it is possible to minimize the possibility that the contents of the container body will remain uninjected without entering the upright inflow passage and the upright inflow passage. Yes,
That is.

図１および図２の正立静止モードでは、操作ボタン１およびステム２がコイルスプリング５の作用により上動して図示の位置に保持されている。 1 and 2, the operation button 1 and the stem 2 are moved upward by the action of the coil spring 5 and are held at the illustrated positions.

このとき、
・ステム２の横孔部２ａはステムガスケット３で閉塞され、
・上方ボール弁８は容器本体内部の大きなガス圧力の作用によって中間部材６の上方弁座に６ａに密接し、
・下方ボール弁９はカバー体７の斜めリブ状部７ｂの上面部分に当接し、
・横孔部２ａより上流側の各通路域には内容物が充足されている。 At this time,
The lateral hole 2a of the stem 2 is closed with the stem gasket 3,
The upper ball valve 8 is brought into close contact with the upper valve seat 6a of the intermediate member 6 by the action of a large gas pressure inside the container body,
The lower ball valve 9 abuts on the upper surface portion of the oblique rib portion 7b of the cover body 7,
-Each passage area upstream from the side hole 2a is filled with contents.

操作ボタン１が押下げられる、すなわちステム２が下方に移動することにより横孔部２ａの閉塞状態は解除される（図３参照）。 When the operation button 1 is pushed down, that is, the stem 2 moves downward, the closed state of the lateral hole 2a is released (see FIG. 3).

そして、容器本体内容物は、図３の黒矢印で示されるように、上記(51)の正立メインルートおよび上記(53)のサブルートを介して外部空間に噴射される。 Then, as shown by the black arrow in FIG. 3, the container body contents are injected into the external space via the upright main route (51) and the sub route (53).

このとき、上方ボール弁８は静止モードのときと同様の下方向へのガス圧力作用により上方弁座６ａに密接し、下方ボール弁９は内容物噴射流を受けて浮き状態になっている。なお、上方ボール弁８の直下の小径縦筒状部６ｃは内容物流出通路の一部であって、当該小径縦筒状部から上方ボール弁８が受ける上方向への内容物圧力（ガス圧力）は上記下方向へのガス圧力よりも十分に小さい。そのため、上方ボール弁８は上方弁座６ａに密接する。 At this time, the upper ball valve 8 is brought into close contact with the upper valve seat 6a by the downward gas pressure action as in the stationary mode, and the lower ball valve 9 is in a floating state by receiving the content injection flow. The small-diameter vertical cylindrical portion 6c directly below the upper ball valve 8 is a part of the content outflow passage, and the upward content pressure (gas pressure) received by the upper ball valve 8 from the small-diameter vertical cylindrical portion. ) Is sufficiently smaller than the gas pressure in the downward direction. Therefore, the upper ball valve 8 is in close contact with the upper valve seat 6a.

利用者が、図３の正立作動モードのバルブ機構をその使用状況に応じて図４に示すような上下逆の倒立作動モードにすると、
(81)それまでの正立作動モードで上方ボール弁８に作用していた下方向（図４の上方向）へのガス圧力（内容物圧力）は特に変化せず、当該ボール弁と上方弁座６ａとの密接状態が維持され、
(82)下方ボール弁９はその自重などで落下して下方弁座６ｂに密接し、
(83)上記(52)，(62)の倒立メインルートおよび倒立用流入通路は上方ボール弁８で遮断され、
(84)上記(63)の正倒立共用通路への内容物流入路は上記(53)の内容物バイパス流Ｃのサブルートのみとなる。 When the user sets the valve mechanism in the upright operation mode in FIG. 3 to the upside-down inverted operation mode as shown in FIG. 4 according to the usage situation,
(81) The gas pressure (content pressure) in the downward direction (upward direction in FIG. 4) that has been acting on the upper ball valve 8 in the upright operation mode is not particularly changed, and the ball valve and the upper valve The close state with the seat 6a is maintained,
(82) The lower ball valve 9 falls due to its own weight, etc., and comes into close contact with the lower valve seat 6b,
(83) The inverted main route and the inflow passage for inversion in the above (52) and (62) are blocked by the upper ball valve 8,
(84) The content inflow path to the upside-down shared passage of (63) is only the sub-route of the content bypass flow C of (53).

なお、図４〜図６の倒立状態のとき、ディップチューブ１０は、その内容物流入側端部が容器本体内部の下側空間域に位置するように屈曲している。また、この屈曲状態を担保するため、必要に応じて、ディップチューブ１０の内容物流入側には周知の重りなどが取りつけられる。 4 to 6, the dip tube 10 is bent so that its content inflow side end is located in the lower space area inside the container body. In order to secure this bent state, a known weight or the like is attached to the contents inflow side of the dip tube 10 as necessary.

エアゾール容器では、容器本体内部の上側空間域に噴射剤（圧縮ガス，液化ガスの気相分）が存在し、下側空間域に噴射対象内容物（原液，粉末）などが存在している。図４〜図６の倒立状態におけるディップチューブ１０の屈曲は、上側空間域の噴射剤ではなく、下側空間域の噴射対象内容物を正倒立共用通路に流入させて操作ボタン１の噴射口１ａから放出するためである。 In an aerosol container, a propellant (gas phase component of compressed gas and liquefied gas) exists in the upper space area inside the container body, and contents to be injected (raw solution, powder) and the like exist in the lower space area. The bending of the dip tube 10 in the inverted state of FIGS. 4 to 6 is not the propellant in the upper space area, but causes the contents to be injected in the lower space area to flow into the normal inverted common passage and the injection port 1a of the operation button 1 It is for releasing from.

ここで図３の正立作動モードから図４の倒立作動モードにシフトした場合、噴射口１ａからの内容物放出量が図３の「Ａ＋Ｃ」から図４の「Ｃ」へと減少する。 Here, when shifting from the upright operation mode of FIG. 3 to the inverted operation mode of FIG. 4, the content discharge amount from the injection port 1 a decreases from “A + C” in FIG. 3 to “C” in FIG. 4.

この内容物放出量の見た目上の減少程度（噴射流の大きさの変化）は、試作品で検証したところ略１／２以下であり、明確に視認できるほどの変化といえる。 The extent of the apparent decrease in the amount of contents released (change in the magnitude of the jet flow) is about ½ or less as verified by the prototype, and can be said to be a change that is clearly visible.

図５に示すように、利用者が、この内容物放出量の激減をみて操作ボタン１の押圧を解除することにより、ステム２はコイルスプリング５の作用で初期位置に復帰してその横孔部２ａがステムガスケット３で閉塞される。 As shown in FIG. 5, when the user releases the pressing of the operation button 1 while seeing a drastic decrease in the content discharge amount, the stem 2 returns to the initial position by the action of the coil spring 5, and the side hole portion 2 a is closed by the stem gasket 3.

その結果、横孔部２ａより上流側である上記(84)の内容物バイパス流Ｃのサブルートが噴射口１ａと遮断された状態になる。 As a result, the sub-route of the content bypass flow C (84), which is upstream of the horizontal hole portion 2a, is blocked from the injection port 1a.

この遮断状態での内容物バイパス流Ｃにより、図５の上方ボール弁８の直上の小径縦筒状部６ｃの圧力も大きくなっていく。そして、概略、上方ボール弁８に対し「下方向に作用する（小径縦筒状部６ｃの）圧力＋上方ボール弁の自重」が「上方向に作用する圧力」を超えた段階で、当該上方ボール弁は落下する。 Due to the content bypass flow C in the shut-off state, the pressure in the small-diameter vertical cylindrical portion 6c immediately above the upper ball valve 8 in FIG. 5 also increases. In general, when the “pressure acting on the lower side (the small diameter vertical cylindrical portion 6c) + the weight of the upper ball valve” on the upper ball valve 8 exceeds the “pressure acting on the upper side”, The ball valve falls.

この上方ボール弁８の落下により、図６に示すように、上記(52)の倒立メインルートが確保されて、操作ボタン１の噴射口１ａからは倒立使用時の本来の流れである（Ｂ＋Ｃ）が放出される。 Due to the fall of the upper ball valve 8, as shown in FIG. 6, the inverted main route (52) is secured, and the original flow from the injection port 1a of the operation button 1 during the inverted use (B + C). Is released.
