Description

【発明の属する技術分野】
【０００１】
本発明はトリガー式液体噴出器に関する。
【０００２】
【従来の技術】
トリガー式の液体噴出器は、容器体口頸部外面へ嵌合させる装着筒の上部内から垂直筒を起立すると共に、該垂直筒上端から射出筒を前方突設し、又該射出筒前部に枢着させてトリガーを垂下し、又上記垂直筒から前方突設したシリンダ内へプランジャを前方付勢させて嵌合させ、該プラジャ前端を上記トリガー上部後面へ係合させて、トリガー引寄せでシリンダ内液体を、射出筒前端へノズル嵌合筒を介して嵌合させたノズルヘッドのノズル孔から噴出させ、又トリガー解放によりプランジャが前進してトリガーを復帰させ、このとき容器体内液体がシリンダ内へ吸込みされるよう設けてある。
【０００３】
上記液体噴出器にあっては、悪戯でトリガーを引寄せても液体が噴出するから、射出筒前端に嵌合させたノズル嵌合筒とノズルヘッドとに液体吐出路の前半部と後半部とを設け、ノズル嵌合筒に対してノズルヘッドを回動させると、上記液体吐出路の連通が遮断され、ノズルヘッドを元の位置まで戻さなければ液体を噴出させることが不能に形成されている。
【０００４】
【発明が解決しようとする課題】
上記のように、ノズル嵌合筒に対してノズルヘッドを回動させて液体吐出路を開閉するよう設けた液体噴出器においても、液体吐出路閉塞状態のままで度々トリガーを引寄せすると、該トリガーが撓み又弾性復元することで、プランジャが多少後退し又前進することとなり、するとシリンダ内の異常な高圧化で吐出弁を通って、該吐出弁と上記ノズル嵌合筒等が形成する液体吐出路部分との間の射出筒前方部分内に高圧液体が溜ることがあり、このようになると、上記ノズルヘッドを液体吐出路連通位置まで回したとき、その射出筒前方部分内に溜っていた高圧液体が、トリガー操作を行わないに拘わらずノズル孔から噴出することが生じた。又、トリガーを強く引寄せすると、射出筒内の高圧化でノズルヘッドがノズル嵌合筒から外れるおそれもあった。
【０００５】
本発明は、上記ノズルヘッド回動による液体吐出路開閉機能の有無に拘らず、前限位置でトリガーを引寄せ不能に設けることで、既述欠点を解消するものである。
【０００６】
【課題を解決するための手段】
その手段として、容器体口頸部へ嵌合させる装着筒２内から垂直筒３を起立すると共に、該垂直筒上端から射出筒４を、かつ中間部からシリンダ５を、それぞれ前方突出し、又シリンダ内へ前方付勢させて嵌合させたプランジャ６前端部を、上記射出筒前部から揺動可能に垂設したトリガー７の上部後面へ係合させ、更にノズル嵌合筒８の基板９から連結筒部10を後方突設して、該筒部を上記射出筒４の前端部外面へ水密に嵌着させると共に、基板前面から嵌合筒部11を前方突設し、該嵌合筒部外面へ、ノズルヘッド12の周壁14を嵌合させ、トリガーの操作で、容器体内液体を吸上げてノズルヘッド12のノズル孔15から噴出可能に設けたトリガー式液体噴出器において、上記ノズルヘッド12の周壁14後端と基板９外周部前面との間に環状空隙23を形成して、該空隙内の嵌合筒部11部分外面へ、周方向一部外面から側外方に係止板24を突出したリング25を回動自在に嵌合させ、又上記トリガー７上部前面に、前方張出し板部27を介して上方突出板部28を起立するフック29を付設し、トリガー７前限位置で、上記係止板24を上記フック29の上方突出板部28後面に係合させることで、トリガーを引寄せ不能に設けた。
【０００７】
【発明の実施の形態】
１は一般に使用されているタイプのトリガー式液体噴出器である。該液体噴出器は、周知のように容器体の口頸部外面ヘ螺合する装着筒２の上部内から垂直筒３を起立し、かつ該垂直筒上端から射出筒４を、かつ垂直筒の中間部前面からシリンダ５を、それぞれ前方突出し、又シリンダ５内へコイルバネ等で前方付勢させて嵌合させたプランジャ６前端部を、上記射出筒前部に上端部をピン等を用いて枢着することで揺動自在に斜下前方へ垂設したトリガー７の上部後面へ係合させ、該トリガー引寄せ操作によりシリンダ内液体を射出筒内を通って噴出させ、又トリガー復帰によるシリンダ内負圧化で容器体内液体をシリンダ内へ吸込み可能に設けている。
【０００８】
上記射出筒４の前端部外面には、ノズル嵌合筒８の基板９から後方突設した連結筒部１０が水密に嵌着されていると共に、該連結筒部に対して下側に偏心させて、基板９前面から嵌合筒部１１が前方突設され、該嵌合筒部外面へ、ノズルヘッド１２の前壁１３周縁部後面から後方突設した周壁１４内面が回動可能に嵌合されて、ノズルヘッドをノズル嵌合筒に抜出し不能に嵌合させている。これ等ノズル嵌合筒８とノズルヘッド１２とには、射出筒４とノズルヘッド１２の前壁１３中央に穿設したノズル孔１５とを連通する液体吐出路１６が穿設させてある。該液体吐出路は、図示のようにノズル嵌合筒８の基板９中央部から前方突出する弁棒１７外面と、ノズルヘッド１２の前壁１３中央部から上記弁棒１７外面へ水密に嵌合させて後方突設した嵌合筒１８内面とに形成する。即ち、該嵌合筒の後部内面へ筒方向に穿設した第１吐出路１９と、上記弁棒１７の前部外面へ母線方向に穿設した第２吐出路２０とで形成し、図１が示す連通状態から、ノズル嵌合筒８に対してノズルヘッド１２を回動させると、第１吐出路１９が弁棒１７の別の位置へ移動して第２吐出路２０との連通が遮断され、又ノズルヘッド１２を元の位置まで戻すことで、再び図１のように連通するものである。
【０００９】
尚、上記ノズルヘッド回動による液体吐出路開閉機能がなく、上記ノズルヘッド１２がノズル嵌合筒８に対して嵌着固定され、液体吐出路１６が常に開通したノズル構造としてもよい。又、美観や取扱性を考慮して、図示例では垂直筒３、シリンダ５、射出筒４が、これらと一体成形されたカバー２１により包囲されているが、勿論、このようなカバーはなくてもよい。
尚、以上述べた構成は従来公知のものである。
【００１０】
以下、本発明について説明すると、上記ノズルヘッド１２の周壁１４後端と、嵌合筒部１１基端上部より外方に延在する基板９の外周部２２前面との間に環状空隙２３が形成されており、該空隙内の嵌合筒部１１部分外面へ、図２に示したように、周方向一部外面から側外方に係止板２４を突出した、上記環状空間の巾よりやゝ小さな肉厚のリング２５を回動自在に嵌合させている。リング２５は、係止板２４やリング外面を指で回すことで回動させることもできるが、回動を容易にするため、リング周方向の適宜位置に、適宜形状、個数の突起乃至は把手を付設することが望ましい。図示例では、リング２５の係止板２４とは周方向反対側の一部外面から側外方に把手板２６が突出し、ノズル嵌合筒基板外周部２２が形成している回動空間内で前後に揺動することなく安定して回動自在とされ、かつカバー２１上端から上方に延在して、手動操作を障害なく行えるようにしている。
【００１１】
又上記トリガー７上部前面に、前方張出し板部２７を介して上方突出板部２８を起立するフック２９が付設されている。
【００１２】
図３に示したように、トリガー７前限位置で、把手板２６を基板外周部２２前面が形成している回動空間内で、想像線で示した横倒位置から、実線で示した直立位置まで回転させると同時に、上記係止板２４を、トリガー７上部前面が形成している回動空間内で時計回りに回転させ、上記フック２９の上方突出板部２８後面に係合させることで、トリガーが引寄せ不能になり、逆に把手板を該直立位置から横倒位置まで回転させ、上記係止板２４をフック２９から係脱させることで、トリガーが引寄せ可能となる。
【００１３】
【発明の効果】
本発明は、既述構成を有するものであり、請求項１記載のトリガー式液体噴出器は請求項１記載のとおり、ノズルヘッド１２の周壁１４後端と基板９外周部前面との間に環状空隙２３を形成して、該空隙内の嵌合筒部１１部分外面へ、周方向一部外面から側外方に係止板２４を突出したリング２５を回動自在に嵌合させ、又上記トリガー７上部前面に、前方張出し板部２７を介して上方突出板部２８を起立するフック２９を付設し、トリガー７前限位置で、上記係止板２４を上記フック２９の上方突出板部２８後面に係合させることで、トリガーを引寄せ不能に設けたため、ノズルヘッド回動による液体吐出路開閉機能の有無に拘らず、既述従来例の場合のように、トリガー前限位置で誤ってトリガーを引寄せすることで、トリガー下部が撓み又弾性復元しても、トリガー上部が係止板２４と係合して不動の状態となっているため、プランジャが誤って後退する恐れが全く無く、従って既述した高圧液体の噴出やノズルヘッドの外れといった事故を完全に防止することが出来る。

[0001]
The present invention relates to a trigger type liquid ejector.
[0002]
[Prior art]
The liquid ejector of the trigger type is configured such that a vertical cylinder is erected from the upper part of the mounting cylinder to be fitted to the outer surface of the neck of the container body, an injection cylinder projects forward from an upper end of the vertical cylinder, and a front part of the injection cylinder is provided. And the plunger is urged forward into the cylinder projecting forward from the vertical cylinder to engage the plunger, and the front end of the plunger is engaged with the upper rear surface of the trigger to draw the trigger. Then, the liquid in the cylinder is ejected from the nozzle hole of the nozzle head fitted to the front end of the injection cylinder via the nozzle fitting cylinder, and the release of the trigger causes the plunger to advance and return the trigger. It is provided so as to be sucked into the cylinder.
[0003]
In the above liquid ejector, since the liquid is ejected even if the trigger is pulled by mischief, the first half and the second half of the liquid ejection path are provided to the nozzle fitting cylinder and the nozzle head fitted to the front end of the injection cylinder. When the nozzle head is rotated with respect to the nozzle fitting cylinder, the communication of the liquid discharge path is interrupted, and it is impossible to eject the liquid unless the nozzle head is returned to the original position. .
[0004]
[Problems to be solved by the invention]
As described above, even in the liquid ejector provided to open and close the liquid discharge path by rotating the nozzle head with respect to the nozzle fitting cylinder, if the trigger is frequently pulled while the liquid discharge path is closed, the When the trigger is bent or elastically restored, the plunger retreats or moves forward a little, and then the fluid formed between the discharge valve and the nozzle fitting cylinder and the like passes through the discharge valve due to abnormally high pressure in the cylinder. In some cases, high-pressure liquid may accumulate in the front portion of the injection cylinder between the discharge path and the nozzle head. When this occurs, when the nozzle head is turned to the liquid discharge path communication position, the high-pressure liquid accumulates in the front portion of the injection cylinder. The high-pressure liquid spouted from the nozzle hole regardless of the trigger operation. Further, if the trigger is strongly pulled, the nozzle head may come off from the nozzle fitting cylinder due to a high pressure in the injection cylinder.
[0005]
The present invention solves the above-mentioned drawback by providing a trigger so as not to be pulled at the front end position regardless of the presence or absence of the liquid discharge path opening / closing function by the rotation of the nozzle head.
[0006]
[Means for Solving the Problems]
As means therefor, the vertical cylinder 3 is erected from the inside of the mounting cylinder 2 to be fitted to the mouth and neck of the container body, the injection cylinder 4 is projected forward from the upper end of the vertical cylinder, and the cylinder 5 is projected forward from the middle part. The front end of the plunger 6 fitted by being urged forward into the inside is engaged with the upper rear surface of the trigger 7 which is swingably suspended from the front of the injection cylinder, and further from the substrate 9 of the nozzle fitting cylinder 8. The connecting cylinder portion 10 is projected rearward, the cylinder portion is fitted watertight to the outer surface of the front end portion of the injection cylinder 4, and the fitting cylinder portion 11 is projected forward from the front surface of the substrate. A trigger-type liquid ejector provided with a peripheral wall 14 of a nozzle head 12 fitted to an outer surface thereof, which is provided so as to be capable of sucking up liquid in the container and ejecting the liquid from a nozzle hole 15 of the nozzle head 12 by operating a trigger. An annular gap 23 is formed between the rear end of the peripheral wall 14 of the Then, a ring 25 having a locking plate 24 projecting outwardly from a part of the outer surface in the circumferential direction is rotatably fitted to the outer surface of the fitting cylindrical portion 11 in the space. A hook 29 for raising the upper protruding plate portion 28 via a front protruding plate portion 27, and engaging the locking plate 24 with the rear surface of the upper protruding plate portion 28 of the hook 29 at the front end position of the trigger 7. By doing so, the trigger was set to be unpullable.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Reference numeral 1 denotes a commonly used type of trigger type liquid ejector. As is well known, the liquid ejector raises the vertical cylinder 3 from the upper part of the mounting cylinder 2 screwed to the outer surface of the mouth and neck of the container body, and the injection cylinder 4 from the upper end of the vertical cylinder. The front end of the plunger 6, which is projected forward from the front of the intermediate portion and is fitted into the cylinder 5 by being urged forward by a coil spring or the like, is pivoted to the front end of the injection cylinder using a pin or the like. The trigger 7 pulls the liquid in the cylinder through the injection cylinder by the trigger pulling operation. It is provided so that the liquid in the container can be sucked into the cylinder by reducing the pressure.
[0008]
On the outer surface of the front end portion of the injection cylinder 4, a connecting cylinder 10 projecting rearward from the substrate 9 of the nozzle fitting cylinder 8 is fitted in a watertight manner, and is eccentric to the lower side with respect to the connecting cylinder. The fitting tube 11 protrudes forward from the front surface of the substrate 9, and the inner surface of the peripheral wall 14 projecting rearward from the rear surface of the front wall 13 of the nozzle head 12 is rotatably fitted to the outer surface of the fitting tube. Then, the nozzle head is fitted to the nozzle fitting cylinder so that it cannot be pulled out. The nozzle fitting tube 8 and the nozzle head 12 are provided with a liquid discharge passage 16 that communicates the injection tube 4 with a nozzle hole 15 formed in the center of the front wall 13 of the nozzle head 12. As shown in the figure, the liquid discharge path is fitted watertight to the outer surface of the valve stem 17 projecting forward from the center of the substrate 9 of the nozzle fitting cylinder 8 and the outer surface of the valve stem 17 from the center of the front wall 13 of the nozzle head 12. Then, it is formed on the inner surface of the fitting cylinder 18 projecting rearward. That is, the first discharge passage 19 is formed in the rear inner surface of the fitting tube in the cylinder direction, and the second discharge passage 20 is formed in the front outer surface of the valve stem 17 in the generatrix direction. When the nozzle head 12 is rotated with respect to the nozzle fitting tube 8 from the communication state indicated by, the first discharge path 19 moves to another position of the valve rod 17 and communication with the second discharge path 20 is cut off. By returning the nozzle head 12 to the original position, the nozzle head 12 communicates again as shown in FIG.
[0009]
It should be noted that a nozzle structure in which the nozzle head 12 is fitted and fixed to the nozzle fitting cylinder 8 and the liquid discharge path 16 is always open may be employed without the function of opening and closing the liquid discharge path by the rotation of the nozzle head. Further, in consideration of aesthetics and handling, the vertical cylinder 3, the cylinder 5, and the injection cylinder 4 are surrounded by the cover 21 integrally formed with them in the illustrated example. Is also good.
The configuration described above is conventionally known.
[0010]
Hereinafter, the present invention will be described. An annular gap 23 is formed between the rear end of the peripheral wall 14 of the nozzle head 12 and the front surface of the outer peripheral portion 22 of the substrate 9 extending outward from the upper end of the base of the fitting cylinder 11. As shown in FIG. 2, the locking plate 24 protrudes outwardly from a part of the outer circumferential surface to the outer surface of the fitting cylindrical portion 11 in the space. (4) The small thickness ring 25 is rotatably fitted. The ring 25 can be rotated by rotating the locking plate 24 or the outer surface of the ring with a finger. However, in order to facilitate rotation, an appropriate shape and number of protrusions or handles are provided at appropriate positions in the ring circumferential direction. It is desirable to attach. In the illustrated example, the handle plate 26 protrudes outward and outward from a part of the outer surface of the ring 25 on the side opposite to the locking plate 24 in the circumferential direction, and is formed in the rotation space formed by the nozzle fitting cylinder substrate outer peripheral portion 22. It is rotatable stably without swinging back and forth, and extends upward from the upper end of the cover 21 so that manual operation can be performed without obstacles.
[0011]
Further, a hook 29 is provided on the front surface of the upper portion of the trigger 7 so as to erect an upwardly projecting plate portion 28 via a front extending plate portion 27.
[0012]
As shown in FIG. 3, at the front end position of the trigger 7, the handle plate 26 is moved from the sideways position shown by the imaginary line to the upright position shown by the solid line in the rotation space formed by the front surface of the substrate outer peripheral portion 22. At the same time, the locking plate 24 is rotated clockwise in the rotation space formed by the upper front surface of the trigger 7 and engaged with the rear surface of the upper protruding plate portion 28 of the hook 29. Then, the trigger cannot be pulled, and conversely, the handle plate is rotated from the upright position to the lying position, and the locking plate 24 is disengaged from the hook 29, whereby the trigger can be pulled.
[0013]
【The invention's effect】
The present invention has the above-described configuration, and the trigger-type liquid ejector according to the first aspect has an annular shape between the rear end of the peripheral wall 14 of the nozzle head 12 and the front surface of the outer peripheral portion of the substrate 9 as described in the first aspect. A gap 23 is formed, and a ring 25 having a locking plate 24 projecting outward from a part of the outer surface in the circumferential direction is rotatably fitted to the outer surface of the fitting cylindrical portion 11 in the gap. A hook 29 is provided on the upper front surface of the trigger 7 to raise the upward projecting plate portion 28 via the front extending plate portion 27. At the front end position of the trigger 7, the locking plate 24 is connected to the upward projecting plate portion 28 of the hook 29. By engaging with the rear surface, the trigger is provided so as not to be pulled, regardless of the presence or absence of the liquid ejection path opening / closing function by the rotation of the nozzle head, as in the case of the above-described conventional example, erroneously at the trigger front limit position. Pulling the trigger causes the lower part of the trigger to flex Also, even if the plunger is resiliently restored, the upper portion of the trigger engages with the locking plate 24 and remains immobile, so there is no danger of the plunger being retracted by mistake. Accidents such as slippage can be completely prevented.
