Description

本発明は、エアゾール式製品に用いられる連続噴射機構に関する。
特にエアゾール式製品の操作部をその静止モード位置から例えば押圧操作したときにステム流入弁（＝定量空間域への流入弁）が開いて、閉状態の出力弁との間の定量空間域に内容物を流入させ、その後の押圧操作解除によりステム流入弁が閉じ、出力弁が開いて、定量空間域の流入済み内容物のみを外部空間に噴射させるようにした定量噴射が前提となる場合の、連続噴射機構に関する。 The present invention relates to a continuous injection mechanism used for aerosol products.
In particular, when the operating part of an aerosol type product is pressed from its stationary mode position, for example, the stem inflow valve (= inflow valve to the fixed volume area) opens and the contents in the fixed volume area between the closed output valve When the inflow of the material, the stem inflow valve is closed by the release of the subsequent pressing operation, the output valve is opened, and the quantitative injection is performed on the assumption that only the inflowed contents in the fixed space area are injected into the external space, The present invention relates to a continuous injection mechanism.

定量噴射タイプのエアゾール式製品では、噴射剤として液化ガス（以下、必要に応じて「噴射用ガス」という。）が用いられ、この液化ガスと噴射対象物とのいわば混合物（溶解物）が外部空間に噴射されることになる。 In the aerosol-type products of the fixed injection type, liquefied gas (hereinafter referred to as “injection gas” if necessary) is used as a propellant, and the so-called mixture (dissolved material) of this liquefied gas and the injection target is external. It will be injected into the space.

本明細書では、このように容器から外部空間へ定量・連続噴射される「噴射対象物＋噴射剤」を「内容物」という。 In this specification, the “injection object + propellant” that is quantitatively and continuously injected from the container to the external space in this way is referred to as “content”.

また、静止モード位置の操作部を例えば押圧してこれを解除したときに定量空間域の流入済み内容物が外部空間に噴射される定量噴射機構を「逆定量噴射機構」と表現する。ただ、この逆定量噴射機構における通常の噴射操作自体については「定量噴射操作」のままを用いる。 In addition, a quantitative injection mechanism that injects the content that has already flowed into the quantitative space area into the external space when the operation unit at the stationary mode position is pressed and released, for example, is expressed as an “inverse quantitative injection mechanism”. However, the “quantitative injection operation” is used as the normal injection operation itself in the reverse quantitative injection mechanism.

なお、利用者にとって、この逆定量噴射機構を内容物連続噴射モードに設定する場合、一般にはエアゾール容器の廃棄に先立って容器内部が空状態になるまで当該モードを継続したときなどには「ガス抜き」と意識し、それ以外の状況では「内容物の（定量噴射に代わる）連続噴射」と意識するものといえる。 For users, when setting the reverse quantitative injection mechanism to the content continuous injection mode, generally, when the mode is continued until the inside of the container is emptied prior to the disposal of the aerosol container, It can be said that it is conscious of "excluding" and conscious of "continuous injection of contents (instead of quantitative injection)" in other situations.

本件出願人はすでに上述の逆定量噴射機構、すなわち噴射ボタンの押圧操作時ではなく、この押圧操作を解除したときの当該噴射ボタンの復帰動作にともなって（ステム流入弁と操作部側出力弁との間の）定量空間域の流入済み内容物を外部空間に噴射する、といったタイプの噴射機構を提案している（特許文献１参照）。なお、以下の記載の[ ]付きの数字は当該特許文献１での参照番号を示している。 The present applicant has not already performed the reverse quantitative injection mechanism described above, that is, at the time of pressing the injection button, but with the return operation of the injection button when the pressing operation is released (the stem inflow valve and the operation unit side output valve). A type of injection mechanism has been proposed in which the inflowed contents in the quantitative space region are injected into the external space (see Patent Document 1). In addition, the number with [] of the following description has shown the reference number in the said patent document 1. FIG.

この逆定量噴射機構は、
1. ステム[3]
2. 当該ステムに取り付けられた弁座部[10]
3. 当該ステムおよび当該弁座部の一体化部材に対して上下動可能な態様で設定された噴射ボタン本体[20]
4. 当該弁座部と当該噴射ボタン本体との間に設けられてこのボタン本体を上方向に付勢するコイルスプリング[15]
などの構成部材からなる。 This reverse quantitative injection mechanism
1. Stem [3]
2. Valve seat attached to the stem [10]
3. Injection button body [20] set in such a manner that it can be moved up and down with respect to the integral member of the stem and the valve seat.
4. A coil spring [15] provided between the valve seat and the injection button body to urge the button body upward
It consists of structural members.

そして、弁座部[10]の環状弁座[17]と噴射ボタン本体[20]の環状弁体[27]とで定量空間域の出力弁を構成している。 The annular valve seat [17] of the valve seat portion [10] and the annular valve body [27] of the injection button main body [20] constitute an output valve in a quantitative space region.

噴射ボタン本体[20]を押下げていない静止モードの場合、コイルスプリング[15]の弾性力により出力弁が開いている。このときステム[3]のいわゆる流入弁（＝内容物通過用のステム周面孔部とこれを開閉するステムガスケットとからなる弁）が周知のコイルスプリングの作用により閉じている、ことは勿論である。 In the stationary mode in which the injection button body [20] is not depressed, the output valve is opened by the elastic force of the coil spring [15]. At this time, of course, the so-called inflow valve of the stem [3] (= the valve comprising the stem peripheral surface hole for passing the contents and the stem gasket for opening and closing the same) is closed by the action of a known coil spring. .

噴射ボタン本体[20]をその静止モードの位置から押下げると、先ず当該ボタン本体のみがコイルスプリング[15]の弾性力に抗しながら下動して出力弁が閉じる。 When the injection button body [20] is pushed down from the position of the stationary mode, first, only the button body moves downward while resisting the elastic force of the coil spring [15], and the output valve is closed.

出力弁が閉じた後は、ステム[3]，弁座部[10]および噴射ボタン本体[20]が一体となって、すなわち出力弁が閉じたまま下動してステム流入弁が開き、内容物（噴射対象物）が定量空間域に入り込む。 After the output valve is closed, the stem [3], the valve seat [10], and the injection button body [20] are integrated, that is, the output valve is closed and the stem inflow valve is opened. An object (injection object) enters the quantitative space area.

次に、利用者が噴射ボタンの押下げ操作を止めると、ステム[3]が（ステム用の）コイルスプリングの弾性作用により上動して流入弁は閉じ、かつ、噴射ボタン本体[20]がコイルスプリング[15]の弾性作用により（弁座部[10]に対して）上動して定量空間域の出力弁は開く。そのため、定量空間域の流入済み内容物のみが外部空間に噴射される。
特開２００３−２９９９９１号公報 Next, when the user stops the push-down operation of the injection button, the stem [3] is moved up by the elastic action of the coil spring (for the stem), the inflow valve is closed, and the injection button body [20] Due to the elastic action of the coil spring [15] (relative to the valve seat [10]), the output valve in the fixed space area opens. For this reason, only the inflowed contents in the quantitative space region are injected into the external space.
JP 2003-299991 A

本件出願人は、以上の逆定量噴射機構について更なる考察，検討，試作を重ねた結果、噴射ボタン本体付勢用の上記コイルスプリング[15]を省略しても、ステムの静止モードへの復帰の際に、定量空間域の出力弁がそこに流入済みの内容物の圧力で「開」状態になる、すなわち定量空間域への流入内容物が外部空間に確実に噴射されることを検証した。 As a result of further consideration, examination, and trial production of the reverse quantitative injection mechanism described above, the applicant of the present application returns the stem to the stationary mode even if the coil spring [15] for energizing the injection button body is omitted. In this case, it was verified that the output valve of the quantitative space area is in an “open” state with the pressure of the contents already flowing into the valve, that is, the inflow contents into the quantitative space area are reliably injected into the external space. .

そして、この検証に基づいて噴射ボタン本体付勢用の上記コイルスプリング[15]を省略した形の逆定量噴射機構をすでに提案している（特願２００６−０２８３３９参照）。 And based on this verification, the reverse fixed quantity injection mechanism of the form which abbreviate | omitted the said coil spring [15] for energizing an injection button main body has already been proposed (refer patent application 2006-028339).

FIG. 1 shows the content continuous injection mode (= the valve seat 4 is locked to the cylindrical base 7 at the lower position thereof, the inflow valve v1 of the stem 3 is opened, and the injection gas in the reverse quantitative injection mechanism of the present invention. The output valve v2 is also opened due to the pressure of the inside of the container and the external space is in communication)
FIG. 2 shows a stationary mode of the reverse quantitative injection mechanism of FIG. 1 (= the state where both the inflow valve v1 and the output valve v2 are closed without the injection button 5 being operated),
FIG. 3 shows a content inflow mode (= the injection button 5 is pushed, the inflow valve is opened, and the output valve is kept closed) into the fixed volume region of the reverse quantitative injection mechanism of FIG.
FIG. 4 shows a content quantitative injection mode from the quantitative space region of the reverse quantitative injection mechanism of FIG. 1 (= the state in which the pressing operation of the injection button 5 is released, the inflow valve is closed, and the output valve is open),
FIG. 5 shows the continuous injection mode setting means for the contents in the reverse quantitative injection mechanism of FIG. 1 (part 1: a two-step operation in which the injection button 5 at the stationary mode position is rotated in the direction E of FIG. 7 and then pushed down). Indicate

FIG. 7 shows the continuous injection mode setting means (part 3: one-step operation only for rotating the injection button 5 in the stationary mode position in the E direction) in the reverse quantitative injection mechanism of FIG.

なお、図２の「静止モード」とは、その状態の噴射ボタンを利用者が下方に押圧することによりステムが下動して定量空間域への流入弁が開き、また、利用者が当該押圧操作を解除することにより周知のステム付勢用のコイルスプリング（図示省略）の作用で噴射ボタンが元の位置に復帰して当該流入弁が閉じる態様の、モードである。 Note that the “static mode” in FIG. 2 means that when the user presses the injection button in that state downward, the stem moves downward to open the inflow valve to the fixed volume area, and the user presses the press button. This mode is a mode in which the injection button is returned to the original position and the inflow valve is closed by the action of a known coil spring for biasing the stem (not shown) by releasing the operation.

上述したように、本発明の前提となる図示の逆定量噴射機構の場合、
(1)図２の静止モード（流入弁ｖ１：閉，出力弁ｖ２：閉）位置の噴射ボタン５を下方に押圧操作することにより図３の内容物流入モード（流入弁：開，出力弁：閉）に移行し、
(2)この内容物流入モードにおいて容器本体の内容物が定量空間域Ｂに流入し、
(3)噴射ボタン５の押圧操作の解除により図４の内容物定量噴射モード（流入弁：閉，出力弁：開）に移行し、
(4)この内容物定量噴射モードにおいて定量空間域Ｂに流入済みの内容物が外部空間に噴射される。 As described above, in the case of the illustrated reverse quantitative injection mechanism which is a premise of the present invention,
(1) The content inflow mode (inflow valve: open, output valve: in FIG. 3) is operated by pressing down the injection button 5 in the stationary mode (inflow valve v1: closed, output valve v2: closed) position in FIG. Closed)
(2) In this content inflow mode, the content of the container body flows into the quantitative space area B,
(3) When the pressing operation of the injection button 5 is released, the content quantitative injection mode (inflow valve: closed, output valve: open) of FIG.
(4) In this content quantitative injection mode, the content that has already flowed into the quantitative space region B is injected into the external space.

図１の内容物連続噴射モードでは、ステム３と一体の弁座部４が筒状基部７との係合作用により図３の内容物流入モード位置に保持され、かつ、定量空間域Ｂの噴射剤（液化ガス）の圧力により噴射ボタン５が弁座部４に対して上動した図４の内容物定量噴射モード位置に移行している。 In the content continuous injection mode of FIG. 1, the valve seat 4 integrated with the stem 3 is held at the content inflow mode position of FIG. The injection button 5 is moved up to the valve seat portion 4 by the pressure of the agent (liquefied gas), and shifts to the content quantitative injection mode position of FIG.

すなわち、定量空間域Ｂの流入弁ｖ１および出力弁ｖ２はともに開状態になっている。これにより容器本体の内容物は、矢印Ａで示すように「容器本体−ハウジング２−流入弁ｖ１（横孔部３ｂ）−通路域３ａ（定量空間域Ｂ）−Ｌ字状溝部４ｂ（定量空間域Ｂ）−出力弁ｖ２−小径垂下部５ａの内部空間域−噴射用ピース６の通路域６ａ−噴射口６ｂ」などを経て外部空間に噴射される。 That is, both the inflow valve v1 and the output valve v2 in the quantitative space region B are open. As a result, the contents of the container main body, as indicated by an arrow A, “container main body—housing 2—inflow valve v1 (horizontal hole 3b) —passage area 3a (quantitative space area B) —L-shaped groove 4b (quantitative space) Area B) -output valve v2-internal space area of small diameter hanging part 5a-passage area 6a of injection piece 6-injection port 6b ", etc.

図２の静止モードでは、通常のエアゾール式製品と同様にステム３がステム付勢用コイルスプリング（図示省略）の弾性力に基づいて上動し、当該ステムの横孔部３ｂは周知のステムガスケット（図示省略）で閉塞される。すなわち定量空間域Ｂの流入弁は「閉」状態になっている。 In the stationary mode of FIG. 2, the stem 3 moves up based on the elastic force of a coil spring for biasing the stem (not shown) as in a normal aerosol type product, and the lateral hole portion 3b of the stem is a well-known stem gasket. It is blocked by (not shown). That is, the inflow valve in the quantitative space region B is in the “closed” state.

噴射ボタン５は、その小径垂下部５ａの内側下端部分が（ステム３と一体の）弁座部４の円錐台状部４ａに当接した状態になっている。 The injection button 5 is in a state where the inner lower end portion of the small-diameter hanging portion 5a is in contact with the truncated cone portion 4a of the valve seat portion 4 (integrated with the stem 3).

なお、前回の内容物定量噴射モード（図４参照）における出力弁ｖ２の開き（＝円錐台状部４ａと小径垂下部５ａとの間隔）の程度や、中径垂下部５ｂの内周面と弁座部４の逆スカート部４ｃとの摩擦力の大きさに応じて、小径垂下部５ａの内側下端部と円錐台状部４ａとがわずか離間した形の静止モードになることもある。 It should be noted that the degree of opening of the output valve v2 in the previous content quantitative injection mode (see FIG. 4) (= the interval between the truncated cone portion 4a and the small diameter hanging portion 5a) and the inner peripheral surface of the medium diameter hanging portion 5b Depending on the magnitude of the frictional force with the reverse skirt portion 4c of the valve seat portion 4, there may be a stationary mode in which the inner lower end portion of the small diameter hanging portion 5a and the truncated cone portion 4a are slightly separated.

図３の内容物流入モードは、利用者が静止モードの噴射ボタン５を押圧して、当該噴射ボタン，弁座部４およびステム３が一体となって押下げられた状態である。 The content inflow mode of FIG. 3 is a state in which the user presses the injection button 5 in the stationary mode, and the injection button, the valve seat portion 4 and the stem 3 are pressed together.

このとき、小径垂下部５ａ（噴射ボタン５）の内側下端部分が弁座部４の円錐台状部４ａに密接し、かつ、ステム３の横孔部３ｂが、通常のエアゾール式製品の場合と同じようにそれまでのステムガスケット（図示省略）による閉塞から解除された状態になる。 At this time, the inner lower end portion of the small-diameter hanging portion 5a (injection button 5) is in close contact with the truncated cone portion 4a of the valve seat portion 4, and the lateral hole portion 3b of the stem 3 is a normal aerosol type product. Similarly, it will be in the state released from the blockage by the previous stem gasket (not shown).

すなわち定量空間域Ｂの流入弁ｖ１が開き、出力弁ｖ２が閉じることになり、容器本体の内容物が矢印Ｃで示すように「横孔部３ｂ−通路域３ａ−Ｌ字状溝部４ｂ」を経て当該定量空間域に流入して収納される。 That is, the inflow valve v1 in the fixed volume area B is opened and the output valve v2 is closed, and the contents of the container main body are indicated by an arrow C so that the “lateral hole portion 3b-passage region 3a-L-shaped groove portion 4b” is formed. Then, it flows into the quantitative space area and is stored.

図４の内容物定量噴射モードは、利用者が噴射ボタン５の押圧操作を解除して、
(11)ステム３がステム付勢用コイルスプリング（図示省略）の弾性力により上動して図２の静止モードの位置に復帰し、その横孔部３ｂ（流入弁ｖ１）が通常のエアゾール式製品の場合と同じようにステムガスケット（図示省略）で閉塞され、
(12)かつ、定量空間域Ａに流入済みの噴射剤の圧力により噴射ボタン５が弁座部４に対して上動し、出力弁ｖ２が開いた、
状態になっている。 In the content quantitative injection mode of FIG. 4, the user releases the pressing operation of the injection button 5,
(11) The stem 3 is moved up by the elastic force of the stem energizing coil spring (not shown) to return to the position of the stationary mode shown in FIG. 2, and its horizontal hole 3b (inflow valve v1) is a normal aerosol type. As with the product, it is closed with a stem gasket (not shown)
(12) In addition, the injection button 5 is moved up with respect to the valve seat portion 4 by the pressure of the propellant that has already flowed into the fixed volume area A, and the output valve v2 is opened.
It is in a state.

すなわち定量空間域Ｂの流入弁ｖ１が閉じ、出力弁ｖ２が開くことになり、それまで当該定量空間域に収納されていた内容物は、矢印Ｄで示すように「出力弁ｖ２−小径垂下部５ａの内部空間域−噴射用ピース６の通路域６ａ−噴射口６ｂ」などを経て外部空間に噴射される。 That is, the inflow valve v1 in the quantitative space area B is closed and the output valve v2 is opened. The contents stored in the quantitative space area until then are indicated by the arrow “D. It is injected to the external space through the internal space region 5a—the passage region 6a of the injection piece 6—the injection port 6b ”and the like.

ここで、定量空間域Ｂに流入済みの噴射剤の圧力により噴射ボタン５が弁座部４に対して上動するのは、当該噴射ボタンの小径垂下部５ａの下端面部分および、小径垂下部５ａと中径垂下部５ｂとの間の環状空間域の天井面部分のそれぞれに、図示上方向への噴射剤（液化ガス）の圧力が作用するからである。 Here, the injection button 5 moves upward relative to the valve seat portion 4 by the pressure of the propellant that has already flowed into the quantitative space region B. The lower end surface portion of the small diameter hanging portion 5a of the injection button and the small diameter hanging portion This is because the pressure of the propellant (liquefied gas) in the upward direction in the figure acts on each of the ceiling surface portions of the annular space area between 5a and the middle diameter hanging portion 5b.

図３の内容物流入モードおよび図４の内容物定量噴射モードの各動作が担保されるためには、定量空間域Ｂへの流入噴射剤の圧力に関し、
(21)内容物流入モードにおける、ステム３および弁座部４に対して図示下方向に作用する（当該圧力に基づく）荷重が、ステム付勢用の周知のコイルスプリング（図示省略）の上方向への付勢力、例えば2.0kgfよりも小さく、
(22)かつ、内容物定量噴射モードにおける、噴射ボタン５に対して図示上方向に作用する（当該圧力に基づく）荷重が、当該噴射ボタンの自重および、逆スカート部４ｃと中径垂下部５ｂとの間の摩擦力の合力よりも大きい、
ことが必要である。 In order to secure each operation of the content inflow mode of FIG. 3 and the content quantitative injection mode of FIG. 4, regarding the pressure of the inflowing propellant to the quantitative space region B,
(21) In the content inflow mode, the load acting on the stem 3 and the valve seat 4 in the downward direction (based on the pressure) is the upward direction of a well-known coil spring for biasing the stem (not shown). Less than 2.0kgf, for example,
(22) In the content quantitative injection mode, the load acting on the injection button 5 in the upward direction (based on the pressure) is caused by the weight of the injection button, the reverse skirt portion 4c, and the medium diameter hanging portion 5b. Greater than the resultant frictional force between
It is necessary.

これは、例えば上記(21)の要件を満足しないと、上記流入内容物の圧力の作用で弁座部４と噴射ボタン５とが相対的に離れる方向に移動、例えばステム３および弁座部４が図３の位置よりも下動して定量空間域Ｂの出力弁ｖ２が開き、通常の噴射状態になるからである。 For example, if the requirement (21) is not satisfied, the valve seat 4 and the injection button 5 move in a direction away from each other by the action of the pressure of the inflow contents. For example, the stem 3 and the valve seat 4 This is because the output valve v2 in the fixed space B is opened from the position in FIG.

以上の定量空間域Ｂへの流入内容物の圧力に基づく上記荷重は例えば（0.3〜1.5）kgfに設定する。ただ、この数値は単なる一例であって、上記(21)，(22)の要件を満たす任意の値に設定し得ることは勿論である。 The load based on the pressure of the contents flowing into the quantitative space B is set to (0.3 to 1.5) kgf, for example. However, this numerical value is merely an example, and it is needless to say that it can be set to any value that satisfies the requirements (21) and (22).

図４の内容物定量噴射モードにおいて、定量空間域Ｂの流入済み内容物が略外部空間に噴射されて当該定量空間域の内容物圧力がいわば消失すると、噴射ボタン５はその自重で下動して図１の静止モードの位置へ移行する。 In the content quantitative injection mode of FIG. 4, when the inflowed content in the quantitative space region B is substantially injected into the external space and the content pressure in the quantitative space region disappears, the injection button 5 moves down with its own weight. To the position of the still mode shown in FIG.

図５〜図７の内容物の連続噴射モード設定手段のそれぞれに共通する基本的特徴は、通常の使用状態でも容器側に取り付けられたままであるカバー体８（および噴射ボタン５）と容器本体との間の相対的な回動操作をともなって、弁座部４，４(1)およびステム３を流入弁ｖ１の開状態に設定し、保持することである。 The basic features common to each of the continuous injection mode setting means of the contents shown in FIGS. 5 to 7 are the cover body 8 (and the injection button 5) and the container body that remain attached to the container side even in a normal use state. The valve seats 4, 4 (1) and the stem 3 are set to the open state of the inflow valve v1 and held together with the relative rotation operation between the two.

以下の記載では、単なる説明の便宜上、容器本体に対してカバー体８を回動させる形の操作を前提とする。なお、この回動操作に先立って筒状基部７，７(1)，７(2)の連結片７ｈを分離しなければならないことは勿論である。 In the following description, for convenience of explanation, it is assumed that the cover body 8 is rotated with respect to the container body. Needless to say, the connecting pieces 7h of the cylindrical base portions 7, 7 (1), 7 (2) must be separated prior to this turning operation.

図５の連続噴射モード設定手段（その１）の場合、静止モード位置（図２参照）のカバー体８をＥ方向（＝時計方向）に回動操作してから噴射ボタン５を下方に押し込むことにより、弁座部４が内容物連続噴射モード位置に移動して保持される。すなわちエアゾール式製品は内容物連続噴射モード（図１参照）に設定保持される。 In the case of the continuous injection mode setting means (part 1) in FIG. 5, the cover button 8 at the stationary mode position (see FIG. 2) is rotated in the E direction (= clockwise) and then the injection button 5 is pushed downward. Thus, the valve seat portion 4 is moved to and held in the content continuous injection mode position. That is, the aerosol type product is set and held in the content continuous injection mode (see FIG. 1).

図６の連続噴射モード設定手段（その２）の場合は、静止モード位置の噴射ボタン５を下方に押し込んだ状態でカバー体８をＥ方向に回動操作することにより、弁座部４(1)が内容物連続噴射モード位置に移動して保持される。 In the case of the continuous injection mode setting means (No. 2) in FIG. 6, the valve seat 4 (1) is turned by rotating the cover body 8 in the E direction with the injection button 5 in the stationary mode position pushed down. ) Is moved to the content continuous injection mode position and held.

図７の連続噴射モード設定手段（その３）の場合は、静止モード位置のカバー体８をＥ方向に回動操作するだけで、弁座部４(1)が内容物連続噴射モード位置に移動して保持される。 In the case of the continuous injection mode setting means (No. 3) in FIG. 7, the valve seat 4 (1) is moved to the content continuous injection mode position simply by rotating the cover body 8 in the stationary mode position in the E direction. Held.

そして、いずれの連続噴射モード設定手段においてもその設定モードを解除するには、カバー体８を当該モードの設定時（のＥ方向）とは逆方向に回動操作して元の位置まで戻せばよい。 In order to cancel the setting mode in any of the continuous injection mode setting means, the cover body 8 is rotated in the direction opposite to that when the mode is set (in the E direction) and returned to the original position. Good.

ここで、図５の連続噴射モード設定手段（その１）の場合、静止モードにおける弁座部４の固定爪状部４ｇと筒状基部７との位置関係が、その連結片７ｈを取り外した後でカバー体８をＥ方向に回動したときに、弁座部テーパ面４ｊがそれまでの凹状案内部７ｄの位置から基部テーパ面７ｅとの対向状態にスムーズに移行できる形になっている。 Here, in the case of the continuous injection mode setting means (part 1) in FIG. 5, the positional relationship between the fixed claw-like portion 4g of the valve seat portion 4 and the cylindrical base portion 7 in the stationary mode is determined after the connecting piece 7h is removed. When the cover body 8 is rotated in the E direction, the valve seat taper surface 4j can smoothly transition from the position of the concave guide portion 7d so far to the base taper surface 7e.

そのため、連結片７ｈを筒状基部７から取り外した上で、
(31)先ずカバー体８（およびこれと連動する弁座部４，噴射ボタン５）を任意の角度（図示の場合は略９０度以下の範囲）だけＥ方向に回動させて弁座部テーパ面４ｊを基部テーパ面７ｅに対向させ、
(32)その後、噴射ボタン５を下方に押圧して弁座部テーパ面４ｊが基部テーパ面７ｅを乗り越えさせてから、当該押圧操作を解除することにより、
(33)弁座部４およびステム３は、ステム付勢用のコイルスプリング（図示省略）の上方向への付勢力によって、当該弁座部の係止用上面４ｈが筒状基部７の係止用底面７ｆに当接した状態の内容物連続噴射モード（図１参照）に確実に保持される。 Therefore, after removing the connecting piece 7h from the cylindrical base 7,
(31) First, the cover body 8 (and the valve seat 4 and the injection button 5 interlocked therewith) is rotated in the E direction by an arbitrary angle (in the illustrated case, a range of approximately 90 degrees or less) to thereby taper the valve seat. The surface 4j is opposed to the base tapered surface 7e,
(32) Then, after the injection button 5 is pressed downward and the valve seat tapered surface 4j gets over the base tapered surface 7e, the pressing operation is released,
(33) The valve seat portion 4 and the stem 3 are engaged with the stem base biasing coil spring (not shown) by the upward biasing force so that the latching upper surface 4h of the valve seat portion latches the cylindrical base portion 7. The content continuous injection mode (see FIG. 1) in contact with the bottom surface 7f is reliably held.

連結片７ｈを筒状基部７から取り外すには、例えば当該連結片の外側への露出部分を引っ張るなどして薄肉部分７ｊを引き裂けばよい。 In order to remove the connecting piece 7h from the cylindrical base 7, for example, the thin portion 7j may be torn by pulling the exposed portion of the connecting piece to the outside.

なお、弁座部テーパ面４ｊが基部テーパ面７ｅを乗り越えるのはそれぞれ自らの弾性に抗するかたちで変形できるからである。乗り越えた後は自弾性力によって元の形状に復帰する。 The reason why the valve seat taper surface 4j overcomes the base taper surface 7e is that it can be deformed in a manner that resists its own elasticity. After getting over, it will return to its original shape by self-elasticity.

図６の連続噴射モード設定手段（その２）の場合は同じく連結片７ｈを筒状基部７(1)から取り外した上で、
(41)先ず噴射ボタン５を下方に押圧して凸状部４ｋが筒状基部７(1)の係止用段部７ｋよりも下方に位置するようにし、

(43)弁座部４(1)およびステム３は、ステム付勢用のコイルスプリング（図示省略）の上方向への付勢力によって、当該弁座部の凸状部４ｋの上面が筒状基部７(1)の係止用段部７ｋに当接した状態の内容物連続噴射モード（図１参照）に確実に保持される。 In the case of the continuous injection mode setting means (No. 2) in FIG. 6, the connecting piece 7h is also removed from the cylindrical base 7 (1),
(41) First, the injection button 5 is pressed downward so that the convex portion 4k is positioned below the locking step portion 7k of the cylindrical base portion 7 (1).
(42) The cover body 8 (and the valve seat portion 4 (1) and the injection button 5 interlocked with the cover body 8) is pushed at an arbitrary angle (in the case of the range of about 90 degrees or less) while being pressed downward. By releasing the pressing operation after rotating in the E direction,
(43) The valve seat portion 4 (1) and the stem 3 are formed so that the upper surface of the convex portion 4k of the valve seat portion is a cylindrical base portion by the upward biasing force of a coil spring for stem biasing (not shown). 7 (1) is securely held in the content continuous injection mode (see FIG. 1) in contact with the locking step 7k.

図７の連続噴射モード設定手段（その３）の場合は同じく連結片７ｈを筒状基部７(2)から取り外した上で、
(51)カバー体８（およびこれと連動する弁座部４(1)，噴射ボタン５）をＥ方向に回動させることにより、
(52)弁座部４(1)およびステム３は、ステム付勢用のコイルスプリング（図示省略）の上方向への付勢力によって、当該弁座部の凸状部４ｋの上面が筒状基部７(2)の水平状カム面７ｐに当接した状態の内容物連続噴射モード（図１参照）に確実に保持される。 In the case of the continuous injection mode setting means (part 3) in FIG. 7, the connecting piece 7h is also removed from the cylindrical base 7 (2),
(51) By rotating the cover body 8 (and the valve seat portion 4 (1) and the injection button 5 linked thereto) in the E direction,
(52) The valve seat portion 4 (1) and the stem 3 are formed so that the upper surface of the convex portion 4k of the valve seat portion is a cylindrical base by the upward biasing force of a coil spring for stem biasing (not shown). 7 (2) is held in the content continuous injection mode (see FIG. 1) in a state of being in contact with the horizontal cam surface 7p.

ここで、図７の設定手段の弁座部４(1)の凸状部４ｋは、静止モード（＝連結片７ｈが接続されたままで噴射ボタン５が押圧されてない状態）において、その天面部分が筒状基部７(2)の斜め状カム面７ｎの上端側の始まり部分よりも低い位置となるように設定されている。 Here, the convex part 4k of the valve seat part 4 (1) of the setting means in FIG. 7 has its top surface in the stationary mode (= the state in which the injection button 5 is not pressed while the connecting piece 7h is connected). The portion is set to be lower than the starting portion on the upper end side of the oblique cam surface 7n of the cylindrical base 7 (2).

そのため、利用者が連結片７ｈを筒状基部７(2)から取り外してカバー体８と容器側との回動方向における拘束状態を解除した後で、当該カバー体を図示Ｅ方向に回動操作して弁座部４(1)および噴射ボタン５を同じ方向に連動させると、当該弁座部は、その凸状部４ｋが斜め状カム面７ｎに倣いながら下方向へ移動する。 Therefore, after the user removes the connecting piece 7h from the cylindrical base 7 (2) and releases the restraint state in the rotational direction between the cover body 8 and the container side, the cover body is rotated in the direction E in the figure. When the valve seat portion 4 (1) and the injection button 5 are interlocked in the same direction, the valve seat portion moves downward while the convex portion 4k follows the oblique cam surface 7n.

すなわち弁座部４(1)は、周方向に対する当該弁座部のリブ４ｆとカバー体８の内側スリット８ｅとのいわばロック作用により当該カバー体とともに回動しながら下動して、その凸状部４ｋが筒状基部７(2)の水平状カム面７ｐに安定的に保持される。すなわち内容物連続噴射モード（図１参照）に設定される。なお、このときの弁座部４(1)のリブ４ｆは筒状基部７(2)の環状鍔部７ｂの上面近くまで移動している。 That is, the valve seat portion 4 (1) moves downward with the cover body by a so-called locking action of the rib 4f of the valve seat portion with respect to the circumferential direction and the inner slit 8e of the cover body 8, and its convex shape. The portion 4k is stably held on the horizontal cam surface 7p of the cylindrical base 7 (2). That is, the content continuous injection mode (see FIG. 1) is set. At this time, the rib 4f of the valve seat 4 (1) has moved to the vicinity of the upper surface of the annular flange 7b of the cylindrical base 7 (2).

図５〜図７の連続噴射モード設定手段においてその設定モードを解除するには、カバー体８（およびこれと連動する弁座部４，４(1)）を先の回動操作時とは逆の反時計方向（Ｅとは逆の方向）に回して、当該弁座部それぞれの固定爪状部４ｇおよび凸状部４ｋと、筒状基部７，７(1)，７(2)それぞれの係止用底面７ｆ，係止用段部７ｋおよび水平状カム面７ｐとの係合状態を解消させればよい。 In order to cancel the setting mode in the continuous injection mode setting means shown in FIGS. 5 to 7, the cover body 8 (and the valve seat portions 4 and 4 (1) interlocked therewith) is reverse to the previous turning operation. Turn counterclockwise (opposite direction to E), the fixed claw-like portion 4g and convex portion 4k of each valve seat portion, and the cylindrical base portions 7, 7 (1), 7 (2) What is necessary is just to cancel the engagement state with the bottom face 7f for latching, the step part 7k for latching, and the horizontal cam surface 7p.

すなわち弁座部４，４(1)の固定爪状部４ｇ，凸状部４ｋをそれぞれ筒状基部７，７(1)，７(2)の凹状案内部７ｄ，７ｍの部分まで戻せばよい。 That is, the fixed claw-like portion 4g and the convex portion 4k of the valve seat portions 4 and 4 (1) may be returned to the concave guide portions 7d and 7m of the cylindrical base portions 7, 7 (1) and 7 (2), respectively. .

この戻りにともない上下方向への移動が自由になった弁座部４，４(1)は、ステム用コイルスプリングの付勢力により上動してステム３とともに静止モード位置へ自動復帰する。その結果、ステム３の横孔部３ｂが周知のステムガスケットで閉塞され、定量空間域Ｂへの流入弁ｖ１が閉状態となる。 The valve seats 4, 4 (1), which are free to move in the vertical direction along with this return, are moved upward by the urging force of the coil spring for stem and automatically return to the stationary mode position together with the stem 3. As a result, the lateral hole portion 3b of the stem 3 is closed with a well-known stem gasket, and the inflow valve v1 to the quantitative space region B is closed.

なお、マウンティングキャップ１に取り付けられた筒状基部７，７(1)，７(2)に対して弁座部４，４(1)，噴射ボタン５およびカバー体８をセットするには例えば、
(61)先ず、弁座部４，４(1)の位置規制用・連動用の突状部４ｅを噴射ボタン５の溝状部５ｄに入れて、当該弁座部および当該噴射ボタンをいわば単一化し、
(62)続いて、この単一化した弁座部を、その一対の固定爪状部４ｇ，凸状部４ｋと筒状基部７，７(1)，７(2)の一対の凹状案内部７ｄ，７ｍとをそれぞれ一致させながら当該筒状基部の開口域７ｃに入れて、当該弁座部の中央孔部をステム３の出力端部分に強く嵌合させ、
(63)続いて、カバー体８を、その外側スリット８ｆと筒状基部７，７(1)，７(2)の連結片７ｈとを一致させ、またその一対の内側スリット８ｅと弁座部４，４(1)の一対のリブ４ｆとをそれぞれ一致させながら当該筒状基部に押し込んで、当該カバー体の嵌合用突状部８ｃを、上述のようにマウンティングキャップ１の外端環状部分１ｂと（その上側の）筒状基部７の環状鍔部７ｂの下面端部分との間に回動可能な形で、嵌合させればよい。 In order to set the valve seats 4, 4 (1), the injection button 5 and the cover body 8 to the cylindrical bases 7, 7 (1), 7 (2) attached to the mounting cap 1, for example,
(61) First, the position restricting / interlocking protruding portion 4e of the valve seat portions 4 and 4 (1) is inserted into the groove-like portion 5d of the injection button 5, and the valve seat portion and the injection button are simply called. Unify,
(62) Subsequently, the unitized valve seat part is connected to the pair of fixed claw-like parts 4g, the convex part 4k and the pair of concave guide parts of the cylindrical base parts 7, 7 (1), 7 (2). 7d and 7m are made to coincide with each other and put into the opening region 7c of the cylindrical base portion, and the central hole portion of the valve seat portion is strongly fitted to the output end portion of the stem 3,
(63) Subsequently, the cover body 8 has its outer slit 8f aligned with the connecting piece 7h of the cylindrical base 7, 7 (1), 7 (2), and the pair of inner slit 8e and the valve seat. The pair of ribs 4f of 4 and 4 (1) are pushed into the cylindrical base portion while being matched with each other so that the fitting protruding portion 8c of the cover body is connected to the outer end annular portion 1b of the mounting cap 1 as described above. And (on the upper side thereof) may be fitted in a rotatable manner between the lower end portion of the annular flange portion 7b of the cylindrical base portion 7.

これにより弁座部４，４(1)は静止モード（図１参照）に設定される。このとき、カバー体８の内側筒状部８ｂの下端部分は筒状基部７，７(1)，７(2)の環状鍔部７ｂに略当接している。 As a result, the valve seats 4 and 4 (1) are set to the stationary mode (see FIG. 1). At this time, the lower end portion of the inner cylindrical portion 8b of the cover body 8 is substantially in contact with the annular flange portion 7b of the cylindrical base portions 7, 7 (1), 7 (2).

上記(61)の、弁座部４，４(1)の位置規制用・連動用の突状部４ｅを噴射ボタン５の溝状部５ｄに入れる場合、その初期段階で当該突状部が当該溝状部の下側の内周面に当たっているときには互いに遠ざかる方向にいわば弾性変形し、突状部４ｅが溝状部５ｄに入ることにより当該突状部や当該内周面は元の状態に復帰する。 When the projecting part 4e for position regulation / interlocking of the valve seat parts 4 and 4 (1) of the above (61) is put into the groove part 5d of the injection button 5, the projecting part is in the initial stage. When it touches the lower inner peripheral surface of the groove-like portion, it is elastically deformed in a direction away from each other, and the protrusion 4e enters the groove-like portion 5d so that the protrusion and the inner peripheral surface are restored to the original state.
