【発明の属する技術分野】
この発明は、操作釦に手を掛けて押し下げ、噴出管を押し込むことにより、容器本体内の内容物を吐出して噴出管を通して、操作釦に設けるノズル部から液状・霧状・泡状・粉末状等で噴出する噴出容器に関する。化粧用・芳香用・洗浄用・清掃用・殺虫用・除菌用・塗装用などの各種の、特にポンプ式のものにおいて用いると有効な噴出容器に関する。
【0002】
【従来の技術】
従来、この種の噴出容器にあっては、たとえば納入時や輸送時や携行時などに、意に反して操作釦を押し下げ、容器本体内の内容物を誤ってノズル部から噴出することがあった。このような誤りをなくすため、従来の噴出容器の中には、不使用時は、操作釦を押し下げた状態で容器本体側にねじ付けて、操作釦の往復動作を規制するものがある。
【0003】
しかし、このような噴出容器においては、内容物を誤って噴出することを阻止すべく、操作釦を押し下げると、内容物がノズル部から噴出するから、そのたびごとに容器本体内の内容物を無駄に消費することとなる問題があった。また、ポンプ式の噴出容器の場合には適用できるが、エアゾール式の噴出容器には適用できない問題があった。
【0004】
このため、従来の噴出容器の中には、たとえば図11に示すように、容器本体1の口部1aにポンプ装置pを取り付け、そのポンプ装置pのネジキャップ2に上向きの規制突起3を一体に形成し、不使用時は図示するとおりその規制突起3で操作釦4の押し下げを規制し、使用時は該操作釦4を矢示方向に水平回動することにより規制突起3とずらせて操作釦4の押し下げを可能とするものがある(特開平8−98784号公報参照)。
【0005】
【発明が解決しようとする課題】
ところが、このような従来の噴出容器には、
1)規制突起3が常に上向きに突出したままの状態であるから、使用時には操作釦4の押し下げ操作の邪魔になる
【0006】
2)操作釦4が容易に水平回動することにより規制突起3とずれて操作釦4の押し下げが簡単に可能となるから、操作釦4の回動を阻止すべくそれと規制突起3との間にテープ5を貼り付けなければならないなどの面倒がある
【0007】
3)噴出管6のまわりで一部規制突起3のみが上向きに突出し、見栄えがよくない
【0008】
4)不使用時にノズル部4aにほこりがつくことを防ぐには、操作釦4に別途キャップカバーを被せる必要がある
などの問題があった。
【0009】
そこで、この発明の第1の課題は、上述したような噴出容器において、内容物の無駄な消費をなくすとともに、使用時における操作釦の操作性を向上することにある。
【0010】
第2の課題は、不使用時の見栄えをよくするとともに、操作釦が不用意にロック解除されることを防止することにある。
【0011】
第3の課題は、不使用時の見栄えをよくするとともに、別途キャップカバーを被せる必要なく、ノズル部等にほこりがつくことを防止することにある。
【0012】
第4の課題は、ロック部材の位置決め操作性を向上するとともに、位置決め操作の確実性を高めることにある。
【0013】
【課題を解決するための手段】
そのため、この発明は、上述した第1、第3、第4の課題を達成すべく、操作釦を押し下げて噴出管を押し込み、容器本体内の内容物を噴出管を通して、操作釦に設けるノズル部から噴出する噴出容器において、
容器本体に取り付ける取付部材と、その取付部材に係合して上下動可能に設け、不使用時は上動してロック位置とし、操作釦の押し下げを阻止する一方、使用時は下動してロック解除位置とし、その押し下げを可能とするロック部材とを備え
前記ロック部材をロック位置としたとき、そのロック部材内に前記操作釦のノズル部を収納し、該操作釦の上部に設ける段部を前記ロック部材に当てて前記操作釦の押し下げを阻止する一方、
前記取付部材と前記ロック部材のいずれか一方に突部を、他方にその突部が係合する溝部を形成するとともに、その溝部の両端に前記突部が入り込んで前記ロック部材をロック位置またはロック解除位置に位置決めする嵌合凹部を形成してなる、ことを特徴とする。
【0014】
請求項2に係る発明は、上述した第2の課題を達成すべく、そのような請求項1に記載の噴出容器において、ロック部材を筒形状とし、噴出管のまわりに設けてなる、ことを特徴とする。
【0017】
請求項に係る発明は、上述した第4の課題を達成すべく、そのような請求項1または2に記載の噴出容器において、嵌合凹部の入り口に、突部と係合してロック部材の操作にクリック感を付与する小突起を設けてなる、ことを特徴とする。
【0018】
【発明の実施の形態】
以下、図面を参照しつつ、この発明の実施の形態につき説明する。
図1には、この発明による噴出容器における不使用時の中央部分縦断面を示す。図2には、その背面側から見た外観を示す。
【0019】
図中符号10は、ボトル状の樹脂製容器本体である。容器本体10は、内部に内容物として、たとえば化粧用液体を収納してなる。そして、その口部10aに、ポンプ装置Pを取り付ける。
【0020】
ポンプ装置Pは、容器本体10の口部10aに、取付部材であるネジキャップ12をねじ付けることにより取り付ける。ネジキャップ12は、図3(A)および(B)にも示すように、キャップ部14と、その頂部から上向きに高く突出する内筒部15と、低く突出する外筒部16とを備える。
【0021】
キャップ部14には、後述するロック部材18を収納する環状凹部14aを上向きに開口して設ける。内筒部15には、頂部15aに中心孔15bをあける。また、外筒部16には、周方向に間隔をあけて矩形状の切欠き16aを4つ設け、4つの円弧部16bを残すとともに、それらの対向する円弧部16bの周面に各々突部16cを形成してなる。各突部16cは、細長で、中心軸oに対して角度θで傾斜するように設けてなる。
【0022】
そのようなネジキャップ12には、外筒部16の外側に、上から各突部16cを溝部19に係合して、ロック部材18を取り付ける。ロック部材18は、図4ならびに図5(A)および(B)に示すように、上縁外径が下縁外径よりほんの少し小さな筒形状とする。
【0023】
そして、そのロック部材18の内面には、対向する位置に溝部19を形成する。各溝部19は、中心軸oに対して角度θ傾斜する傾斜部19aと、その上端に設ける上嵌合凹部19bと、下端に設ける下嵌合凹部19cとを有する。各嵌合凹部19b・19cの入り口には、突部16cと係合してロック部材18の操作にクリック感を付与する小突起a・bをそれぞれ設けてなる。
【0024】
ロック部材18は、ネジキャップ12に係合して上下動可能に設けるが、図1および図2に示す状態では、回動して上動し、小突起bを乗り越えて突部16cを下嵌合凹部19c内に入れ、突部16cの上端面mに下嵌合凹部19cの下向き段部nを突き当てて該ロック部材18の下動を阻止し、ロック位置で位置決め保持してなる。
【0025】
一方、ネジキャップ12の内筒部15内には、頂部15aに突き当ててパッキン20を入れる。そして、そのパッキン20を圧縮してシリンダ22を収納する。シリンダ22には、下端部外周に吸上げ管23の上端部を取り付ける。吸上げ管23は、下端部を容器本体内10内の底部までのばしてなる。
【0026】
シリンダ22内には、上向き段部上にコイルスプリング24を載せ、そのコイルスプリング24を介してピストン25を収納し、シリンダ室Sを区画する。ピストン25には、シリンダ室S内と外部とを連通する連通路25aを設け、その連通路25aを塞ぐように弾性弁26を取り付けてなる。
【0027】
ピストン25の上部は、噴出管28内に挿入して円錐部25bを下向き段部28aに押し当てる。噴出管28は、ネジキャップ12の中心孔15bを貫通して上向きに突出する一方、下部をシリンダ22内に収納してなる。そして、噴出管28の下部外周28bをシリンダ22の上部内周に押し当ててそのシリンダ22との間を液密に保持するとともに、内筒部15の頂部15aとの間でパッキン20を圧縮してなる。
【0028】
噴出管28の上部には、噴出管28内の噴出路28cと内部流路30aとを連通して操作釦30を取り付ける。操作釦30には、内部流路30aと連通してノズル部31を設け、そのノズル部31に、噴出口32aを有するノズル部材32を取り付ける。図6には、そのノズル部材32を取り付ける前の操作釦30の中央縦断面を示す。そして、この操作釦30は、ロック位置にある上述したロック部材18内にノズル部31を収納し、上部外周の下向き段部30bをロック部材18の上端面と対向してなる。
【0029】
これにより、図1および図2に示す状態では、ロック部材18は上動してロック位置に保持するから、操作釦30の頂面30cに指を掛けて操作釦30を押し下げようとしても、下向き段部30bをロック部材18の上端面に当ててその操作釦30の押し下げを阻止してなる。
【0030】
このように、図示例では、不使用時に、筒形状のロック部材18を上動してロック位置とし、噴出管28のまわりを被って設けるから、見栄えをよくすることができるとともに、ロック部材18内に操作釦30のノズル部31を収納するから、別途キャップカバーを被せる必要なく、ノズル部31等にほこりがつくことを防止することができる。
【0031】
また、突部16cを下嵌合凹部19c内にはめ込んでロック部材18の下動を阻止するから、操作釦30の押し下げを確実にロックすることができる。
【0032】
さて、いま、この噴出容器を使用するときは、ロック部材18を持って回動する。そして、小突起bを乗り越えて突部16cを下嵌合凹部19c内から出し、突部16cの上端面mと下嵌合凹部19cの下向き段部nとの係合を外して溝部19内の傾斜部19a内に入れ、傾斜部19a内を通して突部16cを移動してロック部材18を下動する。
【0033】
そして、ロック部材18の下部をネジキャップ12の環状凹部14a内に収納し、突き当たったところでロック部材18をさらに回動して小突起aを乗り越えて突部16cを上嵌合凹部19b内に入れる。これにより、図7および図8に示すように突部16cの下端面qに上嵌合凹部19bの上向き段部rを突き当てて該ロック部材18の上動を阻止し、ロック部材18を、操作釦30の押し下げを可能とするロック解除位置に位置決め保持する。
【0034】
その後、容器本体10を持って操作釦30の噴出口32aを目的部位に向け、頂面30cに指を当てて操作釦30を押し下げ、図9および図10に示すように噴出管28を押し込んでコイルスプリング24に抗してピストン25を押し下げ、シリンダ室S内の容積を狭めてそのシリンダ室S内の圧力を高める。
【0035】
そして、シリンダ室S内の圧力の高まりとともに、やがて弾性弁26を開き、吸上げ管23を介してシリンダ室S内まで吸上げた容器本体10内の内容物を、連通路25aを通して吐出し、噴出管28に対してピストン25が相対移動して下向き段部28aから円錐部25bを離し、噴出路28cを通して操作釦30の内部流路30aに入れ、操作釦30のノズル部31に設ける噴出口32aから噴出する。
【0036】
ピストン25の内外圧力差が低下すると、コイルスプリング24の付勢力でピストン25が上動して円錐部25bが下向き段部28aに押し当たり、噴出口32aからの内容物の噴出を停止する。その後、操作釦30から指を離すと、コイルスプリング24の付勢力で噴出管28が自動復帰する。
【0037】
使用後は、再びロック部材18を持って今度は逆方向に回動する。そして、小突起aを乗り越えて突部16cを上嵌合凹部19b内から出し、突部16cの下端面qと上嵌合凹部19bの上向き段部rとの係合を外して溝部19内の傾斜部19a内に入れ、傾斜部19a内を通して突部16cを移動してロック部材18を上動する。
【0038】
そして、ロック部材18の下部をネジキャップ12の環状凹部14a内から出し、ロック部材18を上動して回動し、小突起bを乗り越えて突部16cを再び下嵌合凹部19c内に入れ、図1および図2に示すように突部16cの上端面mに下嵌合凹部19cの下向き段部nを突き当てて該ロック部材18の下動を阻止し、ロック部材18をロック位置で位置決め保持してなる。
【0039】
このように、図示例では、使用時は、ロック部材18を下動してロック解除位置とし、操作釦30の押し下げを可能とするから、使用時にはロック部材18が邪魔にならず、操作釦30の操作性を向上することができる。
【0040】
また、各嵌合凹部19b・19cの入り口に、突部16cと係合してロック部材18の操作にクリック感を付与する小突起a・bを設けるから、ロック部材18をロック位置またはロック解除位置に位置決める位置決め操作性を向上するとともに、クリック感により操作を確認して位置決め操作の確実性を高めることができる。
【0041】
なお、ネジキャップ12やロック部材18は、ポリアセタールやポリオレフィン系樹脂などでつくるが、それら両部材を同材質でつくると、クリック感をよくし、一層位置決め操作性を向上するとともに、位置決め操作の確実性を高めることができる。
【0042】
【発明の効果】
したがって、この発明によれば、不使用時は、ロック部材を上動してロック位置とし、操作釦の押し下げを阻止するから、操作釦のロック操作時に容器本体の内容物を無駄に消費することがない。また、使用時は、ロック部材を下動してロック解除位置とし、操作釦の押し下げを可能とするから、ロック部材が邪魔にならず、使用時における操作釦の操作性を向上することができる。ポンプ式の噴出容器に限らず、エアゾール式の噴出容器にも適用することができる。
【0043】
請求項2に係る発明によれば、ロック部材を筒形状とし、不使用時には上動してロック位置とし、噴出管のまわりを被って設けるから、ロック解除の操作性がよく、見栄えもよくすることができる。また、ロック部材を筒形状とするから、ロック部材をロック位置としたとき、ロック部材と操作釦の係合が確実で、不用意に操作釦との係合が外れるおそれがなく、誤って操作釦が押し下げられることもない。
【0044】
また、この発明によれば、不使用時に、ロック部材をロック位置としたとき、そのロック部材内に操作釦のノズル部を収納し、操作釦の上部に設ける段部をロック部材に当てて操作釦の押し下げを阻止するから、不使用時の見栄えをよくするとともに、別途キャップカバーを被せる必要なく、ロック部材で被ってノズル部等にほこりがつくことを防止することができる。
【0045】
さらに、この取付部材とロック部材のいずれか一方に突部を、他方にその突部が係合する溝部を形成するとともに、その溝部の両端に突部が入り込んでロック部材をロック位置またはロック解除位置に位置決めする嵌合凹部を形成するから、ロック部材の位置決め操作性を向上するとともに、位置決め操作の確実性を高めることができる。
【0046】
請求項に係る発明によれば、嵌合凹部の入り口に、突部と係合してロック部材の操作にクリック感を付与する小突起を設けるから、クリック感により操作確認を可能として、同じくロック部材の位置決め操作性を向上するとともに、位置決め操作の確実性を高めることができる。

An operation button 30 is attached to the upper part of the ejection pipe 28 by connecting the ejection path 28 c in the ejection pipe 28 and the internal flow path 30 a. The operation button 30 is provided with a nozzle portion 31 in communication with the internal flow path 30 a, and a nozzle member 32 having a jet port 32 a is attached to the nozzle portion 31. FIG. 6 shows a central longitudinal section of the operation button 30 before the nozzle member 32 is attached. The operation button 30 is configured such that the nozzle portion 31 is housed in the above-described lock member 18 at the lock position, and the downward stepped portion 30 b of the upper outer periphery faces the upper end surface of the lock member 18.
[0029]
Accordingly, in the state shown in FIGS. 1 and 2, the lock member 18 moves upward and is held in the locked position. Therefore, even if the operator presses the operation button 30 down by placing a finger on the top surface 30 c of the operation button 30, The step 30b is applied to the upper end surface of the lock member 18 to prevent the operation button 30 from being pushed down.

The piston 25 is pushed down against the coil spring 24 to reduce the volume in the cylinder chamber S and increase the pressure in the cylinder chamber S.
[0035]
As the pressure in the cylinder chamber S increases, the elastic valve 26 is eventually opened, and the contents in the container body 10 sucked up to the cylinder chamber S through the suction pipe 23 are discharged through the communication passage 25a. The piston 25 moves relative to the ejection pipe 28 to separate the conical portion 25b from the downward stepped portion 28a, enters the internal flow path 30a of the operation button 30 through the ejection path 28c, and is provided at the nozzle portion 31 of the operation button 30. It ejects from 32a.
[0036]
When the internal / external pressure difference of the piston 25 decreases, the piston 25 moves upward by the urging force of the coil spring 24, the conical portion 25b hits the downward stepped portion 28a, and the ejection of the contents from the ejection port 32a is stopped. Thereafter, when the finger is released from the operation button 30, the ejection pipe 28 is automatically restored by the urging force of the coil spring 24.
[0037]
After use, the lock member 18 is held again and this time it rotates in the opposite direction. Then, over the small protrusion a, the protrusion 16c is taken out of the upper fitting recess 19b, the lower end surface q of the protrusion 16c is disengaged from the upward step r of the upper fitting recess 19b, and the groove 19 The lock member 18 is moved upward by moving the protrusion 16c through the inclined portion 19a.
[0038]
Then, the lower part of the lock member 18 is taken out of the annular recess 14a of the screw cap 12, and the lock member 18 is moved upward to rotate, over the small protrusion b, and the protrusion 16c is again inserted into the lower fitting recess 19c. As shown in FIGS. 1 and 2, the downward fitting step 19c of the lower fitting recess 19c is abutted against the upper end surface m of the projection 16c to prevent the lock member 18 from moving downward, and the lock member 18 is locked at the locked position. Positioned and held.
[0039]
In this way, in the illustrated example, when used, the lock member 18 is moved down to the unlocked position, and the operation button 30 can be pushed down. The operability can be improved.
[0040]
In addition, small protrusions a and b are provided at the entrances of the fitting recesses 19b and 19c to engage the protrusions 16c to give a click feeling to the operation of the lock member 18, so that the lock member 18 is locked or unlocked. The positioning operability for positioning to the position can be improved, and the reliability of the positioning operation can be improved by confirming the operation with a click feeling.
[0041]
