Description

本発明はトリガー式液体噴出器に関する。   The present invention relates to a trigger type liquid ejector.

トリガー式液体噴出器は使用の簡便さから数多くの商品が提案され販売されて来た。そのなかで販売する側は商品の特徴を明確にして競合品との差別化を打ち出し、市場に於ける勝ち残りに凌ぎを削っている。その為トリガー式液体噴出器に対してもより高い機能の要求があり微細な均一安定した霧や切れの良い霧及び泡の供給が要求され、それに伴うトリガー式液体噴出器が提案されている。(例えば,特許文献1参照)   Many types of trigger type liquid ejectors have been proposed and sold for ease of use. Among them, the selling side has clarified the characteristics of the product and launched a differentiation from the competitors, surpassing the remaining in the market. For this reason, there is a demand for a higher function than the trigger type liquid ejector, and there is a demand for supplying a fine, uniform and stable mist, a crisp mist and bubbles, and a trigger type liquid ejector has been proposed. (For example, see Patent Document 1)

上記液体噴出器は、操作レバーを繰り返し牽曳して容器体内の液体を吸引,加圧,圧送するポンプと、このポンプを一体的に備え該ポンプによって加圧,圧送された液体を通過させる送給経路を有するボディと、このボディの送給経路の末端に配置され送給経路を通って圧送された液体を外界に向けて噴出する噴射ノズルとを備え、ボディの送給経路内に、該送給経路を閉塞状態に常時保持し、液体の圧力が規定圧力に達したときにのみ送給経路を開放する蓄圧弁を設けている。   The liquid ejector includes a pump that sucks, pressurizes, and pumps the liquid in the container by repeatedly checking the operation lever, and a pump that is integrally provided with the pump and that passes the liquid pressurized and pumped by the pump. A body having a supply path, and an injection nozzle that is disposed at the end of the supply path of the body and jets liquid that has been pressure-fed through the supply path toward the outside. A pressure accumulating valve is provided that always keeps the feed path closed and opens the feed path only when the pressure of the liquid reaches a specified pressure.

この蓄圧弁は、弁体と弾性部材とから構成されている。弁体は、内部を送給経路の一部として構成した縦筒内に上下動可能に装着している。また、弾性部材は、弁体上部に於いて、弁体の開口から内部空間へと入りこみ縦筒内周に形成した上向き段部形態の弁座に弁体周囲の下向き段部形態のシール部を押し当てて縦筒内を閉塞状態に保持する一方、規定圧力に達したときのみ弁座から弁体を離反させる反発力を有する如く構成している。このトリガー式液体噴出器は、ボディの縦筒内に蓄圧弁を挿入し、配置するだけで蓄圧式の液体噴出器に変更することができ、設計変更するなどの余計な手間をかけることなしに液体の均一な噴出が可能な優れたものである。

This pressure accumulation valve is comprised from the valve body and the elastic member. The valve body is mounted so as to be movable up and down in a vertical cylinder having the inside as a part of the feeding path. In addition, the elastic member has an upward stepped valve seat formed on the inner periphery of the vertical cylinder that enters the inner space from the opening of the valve body at the upper part of the valve body, and a seal portion of the downward stepped portion surrounding the valve body. While being pressed to hold the inside of the vertical cylinder in a closed state, it has a repulsive force that separates the valve body from the valve seat only when the specified pressure is reached. This trigger type liquid ejector can be changed to an accumulator type liquid ejector simply by inserting and arranging a pressure accumulating valve in the vertical cylinder of the body, without any extra effort such as changing the design. It is an excellent one that can uniformly eject liquid.

前記従来のトリガー式液体噴出器は、縦筒上端より前方へ射出筒を、その下方より前方へシリンダを、それぞれ延設した本体を備え、射出筒の先端にノズルを嵌着し、トリガー操作によりノズルの噴出口より液を噴出させる如く構成している。一方、この種の液体噴出器の収納液としては、洗浄剤,かび取り等の薬剤,化粧料等その種類は多岐にわたり、その使用形態もそれに伴って多様化しており、特に塗布対象位置が陰に隠れて直接の噴出が困難な部位である状態にも多く遭遇する。その様な場合には前記従来の射出筒の先端にノズルを嵌着したものであっては、好ましい塗布が行えない場合がある。   The conventional trigger type liquid ejector includes a main body extending from the upper end of the vertical cylinder to the front and the cylinder from the lower side to the front, and a nozzle is fitted to the tip of the injection cylinder, and the trigger operation is performed. The liquid is ejected from the nozzle outlet. On the other hand, there are various types of liquids stored in this type of liquid ejector, such as cleaning agents, fungi removal agents, cosmetics, etc., and their usage forms are diversified accordingly. Many people also encounter a situation where it is difficult to erupt directly. In such a case, there is a case where a preferable application cannot be performed if a nozzle is fitted to the tip of the conventional injection cylinder.

本発明は上記した点に鑑みてなされたもので、塗布対象部位が陰に隠れた塗布の行い難い場所であっても簡単に対応できるトリガー式液体噴出器を提案する。また、液の噴出を防止した状態と、噴出が可能な状態とを簡単な操作で切り換えることができ、しかもその切り換えを噴出口の好ましい向きと連動したトリガー式液体噴出器を提案する。   The present invention has been made in view of the above points, and proposes a trigger type liquid ejector that can easily cope with a place where the application target is hidden and is difficult to perform application. In addition, a trigger type liquid ejector that can switch between a state in which ejection of liquid is prevented and a state in which ejection is possible by a simple operation and that is linked to the preferred direction of the ejection port is proposed.

第1の手段として、以下の通り構成した。即ち、本体D内部に備えた液流路の中途にシリンダ23を連通させるとともに、シリンダ23内を摺動するプランジャEの押し込み操作を行うトリガーFを備え、トリガーFの操作により容器体内の液を液流路終端のノズルJより噴出する如く構成したトリガー式液体噴出器に於いて、軸線aを中心に回動可能に本体Dに装着した長尺な首筒62の先端に、前記軸線aに対し噴出口88の開口方向を傾倒した状態でノズルJを装着し、首筒62と一体に回動し、トリガーFの引き込み防止状態から、トリガーFの引き込み可能状態への回動が可能なストッパー67を設け、前記トリガーFの引き込み防止状態で、ストッパー67の基板部67a を軸線aに対して下方に垂設するとともに、噴出口88の開口方向を軸線aに対して下方に傾倒したThe first means is configured as follows. That is, the cylinder 23 is communicated in the middle of the liquid flow path provided in the main body D, and the trigger F for pushing the plunger E sliding in the cylinder 23 is provided. In the trigger type liquid ejector configured to be ejected from the nozzle J at the end of the liquid flow path, the axis a is attached to the distal end of a long neck 62 attached to the main body D so as to be rotatable about the axis a. On the other hand, the nozzle J is mounted in a state where the opening direction of the spout 88 is inclined, and the stopper J can be rotated integrally with the neck tube 62 so that the trigger F can be retracted from the retractable state to the retractable state. In the state where the pull-in of the trigger F is prevented, the substrate portion 67a of the stopper 67 is suspended downward with respect to the axis a, and the opening direction of the spout 88 is tilted downward with respect to the axis a .

の手段として、以下の通り構成した。即ち、前記第1の手段に於いて、一定液圧以上で開弁する蓄圧式の吐出弁94をノズルJ内に設けた。 The second means is configured as follows. That is, at the first hand stage, provided the discharge valve 94 of the accumulator type which opens at a predetermined liquid over pressure or in the nozzle J.

の手段として、以下の通り構成した。即ち、前記第1の手段又はの手段のいずれかの手段に於いて、首筒62内に液の流通が可能に嵌着した充填棒Iを設けた。 The third means was configured as follows. That is, in either the first means or the second means, the filling rod I fitted in the neck tube 62 so as to allow the liquid to flow is provided.

本発明のトリガー式液体噴出器は、軸線aを中心に回動可能に本体Dに装着した長尺な首筒62の先端に、前記軸線aに対し噴出口88の開口方向を傾倒した状態でノズルJを装着しているので、塗布対象位置が物の陰に隠れて直接見えない位置であっても容易に塗布することができ、しかも、首筒62は長尺であるため、比較的奥まった場所でも容易に対処できる。   The trigger type liquid ejector of the present invention is in a state in which the opening direction of the spout 88 is inclined with respect to the axis a at the tip of a long neck cylinder 62 attached to the main body D so as to be rotatable about the axis a. Since the nozzle J is mounted, it can be applied easily even if the application target position is hidden behind the object and cannot be seen directly, and the neck tube 62 is long so that it is relatively deep. It can be easily handled in any place.

首筒62と一体に回動し、トリガーFの引き込み防止状態から、トリガーFの引き込み可能状態への回動が可能なストッパー67を設けた場合には、不使用時にはトリガーの引き込み防止状態にしておけば、誤っての液の噴射を防止できる。また、ストッパー67は回動させるだけで引き込み可能状態となるため、その操作は極めて簡単であり、しかも、それと同時に噴出口88の開口方向も噴射に適した方向に変えることができる利点もある。   When a stopper 67 that can rotate from the state in which the trigger F is retracted to the state in which the trigger F can be retracted is provided, the trigger 67 is prevented from being retracted when not in use. If this is done, it is possible to prevent accidental liquid injection. Further, since the stopper 67 can be retracted only by rotating, its operation is very simple, and at the same time, there is an advantage that the opening direction of the ejection port 88 can be changed to a direction suitable for injection.

一定液圧以上で開弁する蓄圧式の吐出弁94をノズルJ内に設けた場合には、液切れが良く、噴霧粒が小さく、また、円滑で且つ均一な噴出が可能となる。   When a pressure-accumulation type discharge valve 94 that opens at a certain fluid pressure or higher is provided in the nozzle J, liquid breakage is good, spray particles are small, and smooth and uniform ejection is possible.

首筒62内に液の流通が可能に嵌着した充填棒Iを設けた場合には、首筒62内の液圧の安定化を図ることができ、液の流れの安定化を図ることができるものであり、それによって、蓄圧式の吐出弁94に送られる液圧も安定化し、圧力損失を減少してプライミングの回数を少なくでき、より均一な噴出が可能となる。   When the filling rod I fitted in the neck tube 62 so that the liquid can be circulated is provided, the liquid pressure in the neck tube 62 can be stabilized, and the liquid flow can be stabilized. As a result, the hydraulic pressure sent to the accumulator discharge valve 94 is also stabilized, the pressure loss can be reduced, the number of priming operations can be reduced, and more uniform ejection can be achieved.

以下、本発明の実施例の形態を図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The injection cylinder 22 projects from the upper front surface of the outer-layer vertical cylinder 21, and the cylinder 23 projects forward from the lower side. The left and right sides and the rear part of the main body D are covered with a cover 24 formed integrally with the main body D.

シリンダ23は外筒23a と内筒23b とを備えており、外筒23a 内に同心円状に内筒23b を突設し、外筒23a より短い内筒23b 外面と外筒23a 内面との間をシリンダ室Rとして画成している。そして、シリンダ室R後端部の外層縦筒21に設けた透孔25と、外層縦筒21と縦筒13との間に形成した連通溝26とで、シリンダ室R内と射出筒22内とを連通させ、また、連通溝26と縦筒13の上端部に穿設した切欠き15とで、射出筒22内と吸込み弁14下流の縦筒13内とを連通させている。   The cylinder 23 is provided with an outer cylinder 23a and an inner cylinder 23b. The inner cylinder 23b is provided concentrically in the outer cylinder 23a, and the inner cylinder 23b shorter than the outer cylinder 23a is provided between the outer surface and the inner surface of the outer cylinder 23a. A cylinder chamber R is defined. The inside of the cylinder chamber R and the inside of the injection cylinder 22 are formed by a through hole 25 provided in the outer layer vertical cylinder 21 at the rear end of the cylinder chamber R and a communication groove 26 formed between the outer layer vertical cylinder 21 and the vertical cylinder 13. Further, the inside of the injection cylinder 22 and the inside of the vertical cylinder 13 downstream of the suction valve 14 are communicated with each other by the communication groove 26 and the notch 15 formed in the upper end portion of the vertical cylinder 13.

プランジャEは、前端閉塞で後端開口の筒状をなす基部30を備え、外筒23a 内周を液密摺動する前後一対のスカート状をなす外側摺動部31を基部30外周に突設し、内筒23b 外周を液密摺動する内側摺動部32を基部30内周に突設して構成しており、コイルスプリングs1により前方へ付勢させている。 Plunger E includes a base 30 that forms a cylindrical shape with a closed front end and a rear end opening, and a pair of front and rear slidable outer slidable parts 31 that project liquid-tightly slide on the inner periphery of outer cylinder 23a. and constitute the inner sliding portion 32 for liquid-tight sliding inner cylinder 23b outer periphery projecting from the inner circumference of the base 30, thereby urged forward by the coil spring s 1.

トリガーFは、射出筒22の先端部両側に上端部を回動可能に連結してシリンダ23の前方へ揺動可能に垂下させており、プランジャEの先端部に上部を連繋させて係止しており、後方への引き込みによりプランジャEをコイルスプリングs1の付勢力に抗して後方へ移行させる如く構成している。 The trigger F has an upper end pivotably connected to both sides of the tip of the injection cylinder 22 and hangs down to the front of the cylinder 23. The trigger F is connected to the tip of the plunger E with the upper part locked. The plunger E is configured to move backward against the urging force of the coil spring s 1 by pulling backward.

接続部材Gは、射出筒22の先端面に裏面を当接する基板50の裏面より後方へ突設した嵌合筒51を射出筒22外周に嵌合させて装着しており、基板50の前面からは長首部材Hを回動可能に嵌合させる支筒52を突設し、その中央部に透孔53を穿設している。   The connecting member G is mounted by fitting a fitting cylinder 51 projecting rearward from the back surface of the substrate 50 that abuts the back surface to the front end surface of the injection cylinder 22 from the front surface of the substrate 50. Has a support tube 52 for fitting the long neck member H in a rotatable manner, and a through hole 53 is formed in the center thereof.

長首部材Hは、支筒52外周に抜け出しを防止して回動可能に装着筒部60を嵌合させており、装着筒部60の先端より中心側へ延設したフランジ61を介して前方へ首筒62を延設している。従って、首筒62はその軸線aを中心に回動可能に装着されている。また、フランジ61の裏面より支筒52内周に液密摺動可能に嵌合させたシール筒63を突設している。首筒62はノズルJを本体Dより離間した前方に位置させるためのものであり、その長さとしては、この種のトリガー式液体噴出器の一般的な大きさを考慮すれば、例えば、10cm〜30cm位の長さが参考として挙げられるが当然これに限られず、用途等により種々選択することができる。   The long neck member H is fitted to the mounting cylinder part 60 so as to be prevented from coming off from the outer periphery of the support cylinder 52 and to be rotated, and is forward through a flange 61 extending from the tip of the mounting cylinder part 60 to the center side. The neck tube 62 is extended. Accordingly, the neck cylinder 62 is mounted so as to be rotatable about the axis a. Further, a seal cylinder 63 is provided so as to project from the back surface of the flange 61 to the inner periphery of the support cylinder 52 so as to be capable of liquid-tight sliding. The neck 62 is for positioning the nozzle J in front of the main body D. The length of the neck 62 is, for example, 10 cm in consideration of the general size of this type of trigger type liquid ejector. Although the length of about 30 cm is mentioned as a reference, naturally it is not restricted to this, It can select variously by a use etc.

首筒62の先端にはノズルJを嵌着させるための支持筒64を基板65を介して突設している。基板65はノズルJの噴出口を傾倒させるために首筒62に対して下方へ傾いて形成されており、支持筒64は基板65と直交して突設している。また、基板65の前面には蓄圧式の吐出弁体を装着するための小径シリンダ部66を突設している。また、首筒62の内部に充填棒Iを嵌着している。充填棒Iは、首筒62内の液圧の安定化を図り、液の流れの安定化を図るためのものであり、リブ70により首筒62内面との間に液の流路を確保している。   A support tube 64 for fitting the nozzle J is provided at the tip of the neck tube 62 through a substrate 65. The substrate 65 is formed so as to be inclined downward with respect to the neck tube 62 in order to tilt the nozzle J, and the support tube 64 projects perpendicularly to the substrate 65. In addition, a small-diameter cylinder portion 66 for mounting a pressure-accumulation type discharge valve body is projected from the front surface of the substrate 65. A filling rod I is fitted inside the neck cylinder 62. The filling rod I is intended to stabilize the liquid pressure in the neck cylinder 62 and to stabilize the liquid flow. The rib 70 ensures a liquid flow path between the inner surface of the neck cylinder 62 and the rib 70. ing.

装着筒部60の下面からはストッパー67を一体に延設している。ストッパー67は装着筒部60下面中央部より垂設した基板部67a の後縁下部より側方へ伸びる横板67b を延設し、横板67b の外側縁より後方へ支持板67c を延設し、支持板67c の前後方向中間部より内方へトリガーFの後面に当接係止する第1係止板67d を、後端縁よりシリンダ23の外筒23a 前面に当接する第2係止板67e をそれぞれ突設して構成している。従って、ストッパー67は接続部材Gとの接続部分に於ける抗力だけでなく、シリンダ23前面に於ける抗力が働き、二重の抗力により、確実にトリガーFの引き込みを防止できる。   A stopper 67 is integrally extended from the lower surface of the mounting cylinder 60. The stopper 67 extends a horizontal plate 67b extending laterally from a lower part of the rear edge of the substrate portion 67a suspended from the central portion of the bottom surface of the mounting cylinder 60, and extends a support plate 67c backward from the outer edge of the horizontal plate 67b. The first locking plate 67d that contacts and locks the rear surface of the trigger F inwardly from the front-rear intermediate portion of the support plate 67c, and the second locking plate that contacts the front surface of the outer cylinder 23a of the cylinder 23 from the rear edge. 67e is projected and configured. Therefore, the stopper 67 not only acts on the connecting portion with the connecting member G but also acts on the front surface of the cylinder 23, and the double drag can reliably prevent the trigger F from being pulled in.

ノズルJは、支持筒64の外周に抜け出しを防止して周壁80を嵌合させて長首部材Hに嵌着しており、周壁80の前端縁より内方へ延設したフランジ部81より後方へ大径シリンダ部82を延設しており、フランジ部81の内周縁より前方へチップ嵌合筒83を延設している。また、フランジ部81の内周縁部には吐出弁座84を形成している。チップ嵌合筒83内には周囲を周方向複数のリブ85により支持されることにより周囲に液の流通が可能な隙間をあけて支持された芯棒86を設けており、芯棒周囲から前面に亘りスピン形成用の公知のチップ87を嵌着している。このチップ87中央の噴出口88は、軸線aに対して下方に傾倒した状態で開口している。 The nozzle J is prevented from slipping out from the outer periphery of the support cylinder 64 and is fitted to the long neck member H by fitting the peripheral wall 80, and rearward from the flange portion 81 extending inward from the front end edge of the peripheral wall 80. A large-diameter cylinder portion 82 is extended to the front, and a chip fitting cylinder 83 is extended forward from the inner peripheral edge of the flange portion 81. A discharge valve seat 84 is formed on the inner peripheral edge of the flange portion 81. Inside the chip fitting cylinder 83 is provided a core rod 86 that is supported by a plurality of circumferential circumferential ribs 85 so that a liquid can flow around it. A known chip 87 for spin formation is fitted over the entire area. The jet outlet 88 at the center of the tip 87 opens in a state of being tilted downward with respect to the axis a.

吐出弁体Kは、小径シリンダ部66に摺動可能に嵌合させた環状小径摺動部90と、大径シリンダ部82に摺動可能に嵌合させた環状の大径摺動部91とをそれぞれ環状基部92の後部および前部より突設し、また、環状基部92の先端に環状基部92との間の液の流通が可能に弁部93を突設し、コイルスプリングs2により常時前方へ付勢され、弁部93を吐出弁座84に圧接してこの部分に吐出弁94を形成している。 The discharge valve body K includes an annular small diameter sliding portion 90 slidably fitted to the small diameter cylinder portion 66, and an annular large diameter sliding portion 91 slidably fitted to the large diameter cylinder portion 82. the projecting from the rear and front of the annular base 92, respectively, also the distribution can the valve portion 93 of the liquid between the annular base 92 to the tip of the annular base 92 to protrude, normally by the coil spring s 2 The valve portion 93 is urged forward and the valve portion 93 is pressed against the discharge valve seat 84 to form a discharge valve 94 at this portion.

上記の如く構成されたトリガー式液体噴出器1は、図1の状態からストッパー67を回動させるとトリガーFの引き込みが可能となり、また、その際、首筒62が回転するとともに、ノズルJが回転して図2に示す如く上方を向く。次いで、トリガーFを引きプランジャEを後方へ押し込むとシリンダ室R内の加圧液が射出筒22から首筒62を介してノズルJ内に導入される。ここで、大径摺動部91と小径摺動部90との径差で生じる圧力により吐出弁体Kが上流側に押圧されコイルスプリングs2の付勢力に抗して吐出弁94を開いて噴出口88から外部へ噴出される。 In the trigger type liquid ejector 1 configured as described above, when the stopper 67 is rotated from the state shown in FIG. 1, the trigger F can be retracted. At that time, the neck 62 is rotated and the nozzle J is rotated. Rotate and face upward as shown in FIG. Next, when the trigger F is pulled and the plunger E is pushed backward, the pressurized liquid in the cylinder chamber R is introduced into the nozzle J from the injection cylinder 22 through the neck cylinder 62. Here, by opening the discharge valve 94 against the urging force of the coil spring s 2 discharge valve body K is pressed to the upstream side by the pressure generated by the difference in diameter between the large diameter sliding portion 91 and the small-diameter sliding portion 90 It is ejected from the spout 88 to the outside.

トリガーFをある程度まで引いて液の噴出が一定量行われるとコイルスプリングs2の付勢力により吐出弁94が閉じ、次いでトリガーIの押圧を解除すれば、コイルスプリングs1の作用でプランジャEが押圧されシリンダ室R内が負圧化され、吸込み弁14が開いて容器体内の液をシリンダ室R内に導入する。 When the trigger F is pulled to a certain extent and a certain amount of liquid is ejected, the discharge valve 94 is closed by the biasing force of the coil spring s 2 , and then when the trigger I is released, the plunger E is moved by the action of the coil spring s 1. The pressure in the cylinder chamber R is reduced and the suction valve 14 is opened to introduce the liquid in the container into the cylinder chamber R.

図4は他の例を示すもので、図1の例に於いて、ノズルJの先端に開閉可能な蓋板89を設けている。他は図1の例と同様であるため説明を省略する。   FIG. 4 shows another example.
