【０００１】
【産業上の利用分野】
本発明は、エアゾール式容器、詳しくは使用勝手からノズルヘッド天端を指先で押圧し、ノズルヘッド側方から内容液を噴射させる方式のエアゾール式容器において、使用上の種々の便利性を備える。すなわち、ノズルヘッドにロック位置とロック解位置との所定の回動範囲が与えられて、不使用時の誤注出を避け得るとしたところの手当てが、誤ノズルヘッドの脱落のおそれがなく、かつ、該ノズルヘッドの回動操作が嘴状の噴射孔に手を触れることなくしてヘッド側面の把握操作でもって確実になし得、さらには容器から突出のステムがノズルヘッドと取り合う係嵌部である前記噴射孔基部の係止用段状拡径部に確保された不測の押圧衝撃、設計誤差、温度変形等の影響を緩衝吸収するための遊び間隙が無効化されることなく、不使用時の予期しない内容物の漏れを確実に防止することのできるとしたエアゾール式容器に関する。
【０００２】
【従来の技術】
いわゆるヘアースタイリングフォームやシェービングフォーム等は、通常、エアゾール式容器に収納されている。このエアゾール式容器は、容器本体と、当該容器本体に装備のステムに取り付けの合成樹脂製のノズルヘッドと該容器本体に該ノズルヘッドを組付けるための合成樹脂製の組付き体とから構成されているのが一般であり、叙上ノズルヘッドは、例えば実公平３−４４２９７号公報におけるように、組付き体に回動自在に組み付けられると共に所定の回動位置にて例えばノズルヘッド側からの垂下脚と組付き体の該垂下脚降下阻止用の仕切フロアーに穿孔の該垂下脚の降下を許容する透孔の如くのノズルヘッド押圧機構を有し、当該透孔以外の位置の垂下脚が仕切フロアーに突き当たる回動位置をノズルヘッドの押圧を不能にするロック機構としている。
【０００３】
そして、嘴状に形成されるノズルヘッド内の途中で屈曲の注出路に充填の内容液に対しては注出路基部で密なシールを構成してバックアップしなければならず、これが不全であると容器本体上に垂れ流しとなってしまうので、叙上ノズルヘッドとステムとの取り合いは漏れのなきように所定長の密嵌合部が確保されるのが常である。
【０００４】
叙上の嵌合部においては該注出路基部は段状に拡径されていてここにステムが係嵌しておりノズルヘッドの降下でステム天端を係止押圧するものとされている。
【０００５】
なお、叙上係止部にあっては材料の寸法誤差、たわみ等でロック時にあっても誤ってステムに押圧力が作用しないよう所定の遊び代の確保はロック機構が受け持つ内容物の漏れ阻止上当然のこととされている。
【０００６】
【発明が解決しようとする課題】
しかしながら、叙上のエアゾール式容器にあっては、使用上の種々の不便が未解決のままである。すなわち、ノズルヘッドにロック位置とロック解位置との所定の回動範囲が与えられて、不使用時の誤注出を避け得るとしたところの構造において、ノズルヘッドの押し下げ能のみに配慮したために、上方への脱出（側方に突き出される噴出孔部の係止で起り得る）や、該ノズルヘッドが組付き体内に埋没態様に格納されてヘッド側面の指先での把握がなし得ない結果、肝心の回動操作の手掛りが、突出の嘴状の注出路部となり、指先が嘴先端に残留する収容液が汚れる不快、そして、ロック機構における内容物漏れ阻止機能が不確実なことである。
【０００７】
最後の漏れ阻止能不全の因は、ノズルヘッドとステムとの取り合い密嵌合部に残留する内容液による経時固化接着作用にあるものと解される。
【０００８】
すなわち、この部における緩衝能は、ノズルヘッドとステムとの間に摺動が働くことを前提とするが、この密嵌合部では、不可避の叙上残留によりノズルヘッドとステムとは経時接着現象を呈し互いに摺動不可におちいり、前述の誤作動解消用遊び代が無効化されることによる。
【０００９】
本発明は叙上の事情に鑑みなされたもので、その目的とするところは、ノズルヘッドにロック位置とロック解位置との所定の回動範囲が与えられて、不使用時の誤注出を避け得るとしたところの構造において、該ノズルヘッドの脱落のおそれがなく、かつ、該ノズルヘッドの回動操作が嘴状の噴射孔に手を触れることなくしてヘッド側面の抱握操作でもって確実になし得、さらには、噴射孔基部の係止用段状拡径部と上記容器に装備のステムとの嵌着部に確保された不測の押圧衝撃、設計誤差、温度変形等の影響を緩衝吸収するための遊び間隙が無効化されることのないノズルヘッド側方から内容液を噴射させる方式のエアゾール式容器を提供することにある。
【００１０】
【課題を解決するための手段】
上記目的を達成するために本発明のエアゾール式容器は、上端部にステム４を上方付勢状態に突出させたエアゾール式容器である容器本体１と、付設の嘴状の注出路６の基部筒片５を該ステム４に嵌着させたノズルヘッド３と、当該ノズルヘッド３を昇降自在および回動自在に組み込みする該容器本体１の上端部に組付く合成樹脂製の組付き体２とから構成され、適正位置でのみノズルヘッド３押し下げでの液体噴出を可能とするエアゾール式容器において、ノズルヘッド３をその側周壁が組付き体２上端より露呈するように組み込みするものとし、組付き体２とノズルヘッド３との間にはノズルヘッド３抜け止め機構を配設し、ノズルヘッド３にあっては、その周端部から複数の脚片１２を垂設すると共に、該脚片１２の下端部にテーパー面１３を形成して乗上げ部１１を構成し、組付き体２にあっては、組付き体２の脚片１２に対向する箇所に開口部１５を開設した平坦板１４を配設の係合部１０を設け、組付き体２に対するノズルヘッド３のロック方向への回動に伴う係合部１０への乗り上げにより、ノズルヘッドの下動を不能とし、かつ、解ロック方向への回動に伴う脚片１２と開口部１５との一致位置でヘッドの下動を可能とし、平坦板１４の中央開口部の上面周縁部に該筒片５を嵌挿する一部に切欠き２１を形成した短円筒形状の規制筒２０を立設し、平坦板１４の中央開口部に下端部を嵌入させることにより、この規制筒２０内に嵌入する状態となる筒片５の切欠き２１に対向する箇所には、切欠き２１を設けることにより形成された規制筒２０の端縁に周方向から対向する突出高さで突片１９を径方向に突設し、突片１９の規制筒２０の端縁に対する突き当たりにより、組付き体２に対するノズルヘッド３の回動変位限を設定し、切欠き２１とは略反対側となった規制筒２０の外周面部分に径方向に延出した縦薄平板状の肉薄片２２を立設し、この肉薄片２２に対向位置する脚片１２の内側面に、延出端部を肉薄片２２の延出端部に周方向から対向させた縦平板状の弾接片２３を立設し、この肉薄片２２と弾接片２３とは、ノズルヘッド３とロック位置とがロック解位置との間を回動変位する途中で、相互にその延出端部を突き当て、継続するノズルヘッド３の回動により相互に弾性変形して乗り越え、この乗り越え時の勢いの良い弾性復帰動作の軽い衝撃により、パチンという軽い衝撃音と衝撃感が発生するものとし、筒片５とステム４との注出路６に係止用に段状に拡径を施した所定の遊び代確保の嵌着構成を、当該段状拡径部から所定長の密嵌部２４とし、次いでゆるやかに拡径して遊嵌部としたうえで終端のガイド用遊嵌部２５としたものである。
【００１１】
【作用】
組付き体２とノズルヘッド３との嵌挿部に確保のノズルヘッド３抜け止め機構により、ノズルヘッドの脱落のおそれがない。ノズルヘッド３は組付き体２上端より高く位置される結果、ノズルヘッド側面の抱握操作でもってなし得る。
所定長確保のノズルヘッドとステムとの取り合い部は、密嵌部と遊嵌部とに分割された結果、密嵌部が大巾に短縮する。このため、残留液による接着度は低減し、ノズルヘッドとステム間の経時相互摺動不可の現象は解消する。しかし、不可欠の密嵌シールは維持される。
【００１２】
注出路基部下端開口部は遊嵌の組付けガイド部となっているうえに、これに続いて上記の遊嵌部が設けられているので、組み付けに手間取ることはなく、単に、下端開口部が拡がりに開口したのみのものでは得られない滑らかなガイド能を奏する。
【００１３】
【実施例】
以下、本発明の一実施例を、図面を参照しながら説明する。
ノズルヘッド３は、合成樹脂製の有頂円筒体の頂壁下面中央から細円筒形状をした筒片５を垂下設すると共に、有頂円筒体の筒壁１８の下端縁に、等間隔に４つの脚片１２を、筒壁１８の一部を下方に延長した形態で垂設し、この脚片１２の下端部にテーパー面１３を形成して乗り上げ部１１を構成している。
【００１４】
筒片５は、その内部を、筒壁１８の外周面上端部に出口を開口した注出路６の垂直路部分としており、この筒片５の内周面下端部には、拡径した段部が形成されていて、この段部面を押圧面７とすると共に、拡径した部分の口径を、容器本体１の上端部に突出したステム４の外径とほぼ等しくしている。この段状拡径部を、所定長の対ステム４密嵌部２４を経て更に拡径した開口に至るガイド用遊嵌部２５の２段拡径構成とした。
【００１５】
該組付き体２は、容器本体１の上端部に嵌め込みにより不動に組付く合成樹脂製の円筒形状体に成形されており、この円筒形状体の内部を上下に区画する形態で隔壁状に係合部１０を構成する平坦板１４が設けられている。この平坦板１４には、中央にステム４が下方から突出すると共に、組付けられたノズルヘッド３の筒片５が上方から嵌入できる開口部が開設されていると共に、周端部には、ノズルヘッド３の脚片１２に対向して、係合部１０を構成する４つの開口部１５が周方向に沿って等間隔に形成されている。
【００１６】
すなわち、ノズルヘッド３のロック解状態では、乗り上げ部１１の脚片１２の下端部が係合部１０の開口部１５に位置し、ノズルヘッド３は下降し得るので、筒片５の押圧面７は、ステム４の上端面である当接面８に当接し、この状態でノズルヘッド３に押し下げ力が作用すると、押圧面７が当接面８に押し付けられて密接触状態となったまま、ステム４が押し下げられ、内容物が注出される。
【００１７】
このロック解状態からノズルヘッド３を設定方向に回動させると、係合部１０の開口部１５の開口縁に対する乗り上げ部１１のテーパー面１３の乗り上げ動作により、乗り上げ部１１の脚片１２が係合部１０の平坦板１４上に乗り上がる。この乗り上げ部１１の係合部１０に対する乗り上がりにより、ノズルヘッド３は組付き体２に対して上昇変位し、筒片５の押圧面７とステム４の当接面８との間に、ノズルヘッド３および組付き体２に生じる撓み代よりも大きい値の間隙９（遊び代）を形成する。この態様は、図１に示されている。ノズルヘッド３に自ら昇動する能力は無く、押圧解除ではステム４の上方付勢によって押し上げられるのみであり、その後の上記のロック方向への回動による乗り上げ使用でもって、図１に示す間隙９確保の態様が実現する。
【００１８】
ノズルヘッド３の筒壁１８の外周面には、略対称に位置して一対の係止片１６（図１および図４参照）が突設されており、この係止片１６に対向して、組付き体２の周壁の内周面上端部に、係止片１６に上方から係止する周突条状の抜け止め部１７が形成されている。
【００１９】
この係止片１６の抜け止め部１７に対する係止により、組付き体２に対してノズルヘッド３は、回動自在ではあるが抜け出し不能に組付け保持されることになる。
【００２０】
平坦板１４の中央開口部の上面周縁部には、一部に切欠き２１を形成した短円筒形状の規制筒２０（図２参照）が立設されており、平坦板１４の中央開口部に下端部を嵌入させることにより、この規制筒２０内に嵌入する状態となる筒片５の切欠き２１に対向する箇所には、切欠き２１を設けることにより形成された規制筒２０の端縁に周方向から対向する突出高さで突片１９が、径方向に突設されており、突片１９の規制筒２０の端縁に対する突き当りにより、組付き体２に対するノズルヘッド３の回動変位限を限定している。
【００２１】
すなわち、乗り上げ部１１の脚片１２が係合部１０の開口部１５に嵌入した回動位置で、突片１９は規制筒２０の一方の端面に当接して、ノズルヘッド３のロック解位置を設定し、反対に、乗り上げ部１１の脚片１２が係合部１０の平坦板１４上に乗り上げた回動位置で、突片１９は規制筒２０の他方端面に当接して、ノズルヘッド３のロック位置を設定している。
【００２２】
切欠き２１とは略反対側となった規制筒２０の外周面部分には、径方向に延出した縦薄平板状の肉薄片２２（図１および図２参照）が立設されており、この肉薄片２２に対向位置する脚片１２の内側面に、延出端部を肉薄片２２の延出端部に周方向から対向させた縦平板状の弾接片２３（図１および図２参照）が立設されている。
【００２３】
この肉薄片２２と弾接片２３とは、ノズルヘッド３がロック位置とロック解位置との間を回動変位する途中で、相互にその延出端部を突き当て、継続するノズルヘッド３の回動により相互に弾性変形して乗り越え、この乗り越え時の勢いの良い弾性復帰動作の軽い衝撃により、パチンという軽い衝撃音と衝撃感が発生するので、使用者は、この衝撃音を聞くと共に衝撃感を触感することにより、ノズルヘッド３のロック状態を音および触感で知ることができ、これにより好ましい使用感を得ることができる。
【００２４】
なお、係合部１０および乗り上げ部１１は、図示実施例に示した構成に特定されるものではなく、例えば、突起状の係止片１６を乗り上げ部１１とし、抜け止め部１７を、この係止片１６が係合する溝構造として係合部１０とすることも可能である。
【００２５】
【発明の効果】
本発明は、上記した構成となっているので、下記する効果を奏する。
すなわち、従来品にあって未解決のノズルヘッドの不測の脱落が無く、ノズルヘッドのロック、ロック解の回動操作に際しての最も好適なノズルヘッド側面把握を可能とし、さらには、ノズルヘッドとステムの嵌着部に生じる摺動不全を解消して不測の漏れを解消した。これに加え、使用上好適なるロック、ロック解位置を衝撃音をもって知らせる機能をも兼備し、好便性優れるエアゾール式容易を提供する。

[Industrial applications]
INDUSTRIAL APPLICABILITY The present invention has various conveniences in use in an aerosol-type container, more specifically, an aerosol-type container in which the top end of a nozzle head is pressed with a fingertip for convenience of use and a liquid content is ejected from the side of the nozzle head. That is, the nozzle head is provided with a predetermined rotation range between the locked position and the unlocked position, so that the care that allows avoiding erroneous ejection when not in use, without the risk of the erroneous nozzle head falling off, In addition, the rotation operation of the nozzle head can be reliably performed by grasping the side surface of the head without touching the beak-shaped injection hole, and furthermore, by the engaging portion where the stem protruding from the container engages with the nozzle head. A play gap for buffering and absorbing the influence of unexpected pressing impact, design error, temperature deformation, etc. secured at the stepped enlarged diameter portion for locking of the injection hole base is not invalidated, and is not used. The present invention relates to an aerosol-type container capable of reliably preventing unexpected leakage of contents.
[0002]
[Prior art]
So-called hair styling foams, shaving foams and the like are usually stored in aerosol type containers. This aerosol-type container is composed of a container body, a synthetic resin nozzle head attached to a stem mounted on the container body, and a synthetic resin assembly for attaching the nozzle head to the container body. Generally, the nozzle head described above is rotatably assembled to the assembled body as described in, for example, Japanese Utility Model Publication No. 3-44297, and at a predetermined rotation position, for example, from the nozzle head side. A hanging head and a nozzle head pressing mechanism such as a through hole that allows the hanging leg to descend is provided on a partition floor for preventing the hanging leg from descending, and the hanging leg at a position other than the through hole is provided. A rotation mechanism that hits the partition floor is a lock mechanism that disables pressing of the nozzle head.
[0003]
And, for the content liquid of the filling in the bent spout in the middle of the beak-shaped nozzle head, a tight seal must be provided at the base of the spout to back up, and if this is inadequate Since the nozzle head and the stem may run down onto the container body, a tight fitting portion of a predetermined length is always secured so that there is no leakage between the nozzle head and the stem.
[0004]
In the fitting portion described above, the base of the spouting path is enlarged in a stepped manner, and the stem is engaged therewith so that the top end of the stem is locked and pressed by the lowering of the nozzle head.
[0005]
In addition, at the above-mentioned latching part, a predetermined play allowance should be secured to prevent the leakage of the contents held by the locking mechanism so that the pressing force does not accidentally act on the stem even when locking due to dimensional error of the material, bending etc. It has been taken for granted.
[0006]
[Problems to be solved by the invention]
However, in the above-mentioned aerosol type container, various inconveniences in use remain unresolved. That is, in the structure in which the nozzle head is provided with a predetermined rotation range between the lock position and the unlock position to avoid erroneous injection when not in use, only consideration is given to the nozzle head depressing ability. , The nozzle head may escape upward (possibly caused by the locking of the ejection hole protruding to the side), or the nozzle head is assembled and stored in the body in a buried manner, and the finger cannot grasp the side surface of the head. The clue to the pivotal operation of the pivot becomes a projecting beak-shaped spouting path, the fingertip becomes unpleasant to contaminate the liquid remaining at the tip of the beak, and the function of preventing the contents from leaking in the lock mechanism is uncertain. .
[0007]
It is understood that the last cause of the failure to prevent the leakage is due to the time-dependent solidification and adhesion of the content liquid remaining in the close fitting portion between the nozzle head and the stem.
[0008]
In other words, the buffering capacity in this part is based on the premise that sliding occurs between the nozzle head and the stem. And the above-mentioned play allowance for eliminating malfunction is invalidated.
[0009]
The present invention has been made in view of the circumstances described above, and its purpose is to provide a nozzle head with a predetermined rotation range between a lock position and a lock release position, thereby preventing erroneous ejection when not in use. In the structure that can be avoided, there is no risk of the nozzle head falling off, and the rotation operation of the nozzle head can be reliably performed by holding the side of the head without touching the beak-shaped injection hole. Absorbing the impact of unexpected pressing impact, design error, temperature deformation, etc. secured at the fitting portion between the stepped enlarged diameter portion of the injection hole base and the stem mounted on the container It is an object of the present invention to provide an aerosol-type container of a type in which a content liquid is jetted from a side of a nozzle head in which a play gap is not invalidated.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the aerosol-type container according to the present invention comprises a container body 1 which is an aerosol-type container having a stem 4 protruding upward at an upper end portion, and a base cylinder of an attached beak-shaped spout 6. A nozzle head 3 having a piece 5 fitted to the stem 4 and an assembled body 2 made of synthetic resin attached to an upper end of the container body 1 into which the nozzle head 3 is vertically and rotatably incorporated. In an aerosol type container which is configured and capable of ejecting liquid by pushing down the nozzle head 3 only at an appropriate position, the nozzle head 3 is incorporated so that a side peripheral wall thereof is exposed from an upper end of the assembly 2. A nozzle head 3 retaining mechanism is arranged between the nozzle head 3 and the nozzle head 3. In the nozzle head 3, a plurality of leg pieces 12 are suspended from the peripheral end thereof, and Tapered lower end In the assembled body 2, a flat plate 14 having an opening 15 is provided at a position facing the leg piece 12 of the assembled body 2. A portion 10 is provided, and the nozzle head 3 rides on the engaging portion 10 in association with the rotation of the nozzle head 3 with respect to the assembled body 2 in the locking direction. A notch 21 is formed in a part of the flat plate 14 at a part where the cylindrical piece 5 is inserted into the upper peripheral edge of the central opening of the flat plate 14 at a position where the leg piece 12 and the opening 15 coincide with each other. A short cylinder-shaped regulating cylinder 20 is erected, and the lower end thereof is fitted into the central opening of the flat plate 14 so as to face the notch 21 of the tube piece 5 which is fitted into the regulating cylinder 20. The circumferential edge of the regulating cylinder 20 formed by providing the notch 21 The projecting piece 19 protrudes in the radial direction at an opposite projecting height, and the rotational displacement limit of the nozzle head 3 with respect to the assembled body 2 is set by the contact of the projecting piece 19 with the end edge of the regulating cylinder 20. A vertically thin flat plate-shaped thin piece 22 extending in the radial direction is provided on the outer peripheral surface portion of the regulating cylinder 20 on the substantially opposite side to the inner surface of the leg piece 12 opposed to this thin piece 22. A vertical flat plate-like elastic contact piece 23 having an extending end portion facing the extending end portion of the thin piece 22 from the circumferential direction is erected, and the thin thin piece 22 and the elastic contact piece 23 are connected to the nozzle head 3. In the middle of the rotational displacement between the lock position and the unlock position, the extended ends of the nozzle heads 3 abut against each other, and the nozzle head 3 continues to be elastically deformed by the continuous rotation of the nozzle head 3 to get over. The light impact of the elastic return operation with good momentum generates a light impact sound and a sense of impact A fitting structure for securing a predetermined play allowance having a stepped diameter increase for locking in the spouting path 6 between the tubular piece 5 and the stem 4 is provided from the stepped enlarged diameter portion to a predetermined length. The fitting portion 24 is formed, and then the diameter is gradually increased to form a loose fitting portion, and then the guide loose fitting portion 25 at the end is formed.
[0011]
[Action]
The nozzle head 3 is prevented from falling off by the nozzle head 3 retaining mechanism secured at the fitting insertion portion between the assembled body 2 and the nozzle head 3. As a result of the nozzle head 3 being positioned higher than the upper end of the assembly 2, the nozzle head 3 can be held by a gripping operation on the side surface of the nozzle head.
The fitting portion between the nozzle head and the stem having a predetermined length is divided into a close fitting portion and a loose fitting portion, so that the close fitting portion is greatly reduced in width. Therefore, the degree of adhesion due to the residual liquid is reduced, and the phenomenon that the nozzle head and the stem cannot slide with each other over time is eliminated. However, the essential tight seal is maintained.
[0012]
The lower end opening of the base of the spouting path serves as an assembly guide portion for loose fitting, and since the above loose fitting portion is provided subsequently thereto, there is no trouble in assembling. It provides a smooth guiding ability that cannot be obtained by simply opening it in the spread.
[0013]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The nozzle head 3 has a cylindrical member 5 having a thin cylindrical shape hanging down from the center of the lower surface of the top wall of the synthetic resin-made cylindrical body, and the nozzle head 3 is provided at regular intervals on the lower end edge of the cylindrical wall 18 of the top-shaped cylindrical body. The two leg pieces 12 are vertically provided with a part of the cylindrical wall 18 extending downward, and a tapered surface 13 is formed at the lower end of the leg piece 12 to constitute the riding section 11.
[0014]
The inside of the tube piece 5 is a vertical path portion of the pouring path 6 having an outlet opened at the upper end portion of the outer peripheral surface of the tube wall 18. The step surface is used as the pressing surface 7, and the diameter of the enlarged portion is made substantially equal to the outer diameter of the stem 4 protruding from the upper end of the container body 1. The step-shaped enlarged portion has a two-stage enlarged configuration of a guide loose fitting portion 25 which reaches a further enlarged opening through the tight fitting portion 24 for the stem 4 having a predetermined length.
[0015]
The assembled body 2 is formed into a cylindrical shape made of a synthetic resin which is fixed to the upper end of the container main body 1 by being fitted into the upper end portion thereof. A flat plate 14 constituting the joint 10 is provided. The flat plate 14 has a stem 4 projecting from below in the center, an opening through which the tubular piece 5 of the assembled nozzle head 3 can be fitted from above, and a nozzle at the peripheral end. Opposite to the leg pieces 12 of the head 3, four openings 15 forming the engaging portion 10 are formed at equal intervals along the circumferential direction.
[0016]
That is, in the unlocked state of the nozzle head 3, the lower end of the leg 12 of the climbing portion 11 is located at the opening 15 of the engaging portion 10, and the nozzle head 3 can descend. Abuts against the contact surface 8, which is the upper end surface of the stem 4, and when a pressing force acts on the nozzle head 3 in this state, the pressing surface 7 is pressed against the contact surface 8 and remains in a close contact state. The stem 4 is pushed down, and the contents are poured out.
[0017]
When the nozzle head 3 is rotated in the set direction from the unlocked state, the leg piece 12 of the riding portion 11 is engaged by the riding operation of the tapered surface 13 of the riding portion 11 with respect to the opening edge of the opening 15 of the engaging portion 10. It rides on the flat plate 14 of the joint 10. The nozzle head 3 is displaced upward with respect to the assembled body 2 by the climbing of the climbing portion 11 with respect to the engaging portion 10, and the nozzle head 3 is positioned between the pressing surface 7 of the tubular piece 5 and the contact surface 8 of the stem 4. A gap 9 (play allowance) having a value larger than a bending allowance generated in the head 3 and the assembled body 2 is formed. This aspect is shown in FIG. The nozzle head 3 does not have the ability to ascend by itself, and is only pushed up by the upward bias of the stem 4 when the pressure is released. The gap 9 shown in FIG. A mode of securing is realized.
[0018]
A pair of locking pieces 16 (see FIG. 1 and FIG. 4) project from the outer peripheral surface of the cylindrical wall 18 of the nozzle head 3 so as to be located substantially symmetrically. At the upper end of the inner peripheral surface of the peripheral wall of the assembled body 2, a ridge-shaped retaining portion 17 that locks the locking piece 16 from above is formed.
[0019]
By the locking of the locking piece 16 to the retaining portion 17, the nozzle head 3 is rotatably but non-removably mounted on the assembled body 2.
[0020]
At the peripheral edge of the upper surface of the central opening of the flat plate 14, a short cylindrical regulating cylinder 20 (see FIG. 2) having a cutout 21 is provided upright. By fitting the lower end, the portion facing the notch 21 of the tube piece 5 which is in a state of being fitted into the regulating tube 20 is provided at the edge of the regulating tube 20 formed by providing the notch 21. A protruding piece 19 is protruded in the radial direction at a protruding height opposed from the circumferential direction. When the protruding piece 19 abuts against the end edge of the regulating cylinder 20, the rotational displacement of the nozzle head 3 with respect to the assembled body 2 is limited. Is limited.
