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、噴出器本体の前面上部から前部に中心軸を有する射出筒を前方突出させ、該射出筒の前方突出部分外面へノズル孔付きのノズルキャップを嵌合させ、射出筒前部から前後方向への揺動が可能に垂設したトリガーを付勢に抗して後方へ引寄せ操作することで、容器体内液体をシリンダ内へ吸込み、かつ該シリンダ内液体を射出管を介して上記ノズル孔から噴出できるよう設けているが、上記ノズルキャップを射出筒に対して正逆両方向へ回動可能とし、その回動範囲の両端で射出筒側とノズル筒側とにそれぞれ付設した係合部が接して回動が停止し、その一方の回動停止位置で射出筒とノズルキャップとに設けた第1、第2液体噴出通路が遮断され、又他方回動停止位置で上記両通路が連通するよう設けている(特許文献1)。   The trigger type liquid ejector projects an injection cylinder having a central axis from the front upper part to the front part of the ejector main body forward, and a nozzle cap with a nozzle hole is fitted to an outer surface of a front projecting portion of the injection cylinder. By pulling the trigger that is suspended from the front part so that it can swing in the front-rear direction against the biasing operation, the liquid in the container is sucked into the cylinder, and the liquid in the cylinder is injected into the injection pipe. The nozzle cap can be rotated in both forward and reverse directions with respect to the injection cylinder, and attached to the injection cylinder side and the nozzle cylinder side at both ends of the rotation range, respectively. The engaging portion comes into contact with each other to stop the rotation, and at one rotation stop position, the first and second liquid ejection passages provided in the injection cylinder and the nozzle cap are blocked, and at the other rotation stop position, the above-mentioned Both passages are connected (patented) Document 1).

上記構成とすることで、両液体噴出通路遮断位置へノズルキャップを回動させておけば、トリガー操作しても液体噴出しないが、該遮断位置で誤ってトリガー操作すると射出筒内の噴出用液体が高圧化し、そのためトリガー操作をしなくてもノズルキャップを液体噴出通路連通位置へ回すだけで射出筒内液体がノズル孔から噴出することがあった。   With the above configuration, if the nozzle cap is rotated to the both liquid ejection passage blocking position, the liquid will not be ejected even if the trigger operation is performed, but if the trigger operation is mistakenly performed at the blocking position, the ejection liquid in the injection cylinder Therefore, even if the trigger operation is not performed, the in-cylinder liquid may be ejected from the nozzle hole only by rotating the nozzle cap to the liquid ejection passage communication position.

そのため上記遮断位置でのトリガー操作を不能とするためノズルキャップからトリガー前面を覆う操作板を垂下させて、該操作板がトリガー前面を覆う状態で液体噴出通路が遮断し、又ノズルキャップの回動はその操作板を介して行うようにしたトリガー式液体噴出器も知られている(特許文献2)。
実公昭60−27482号公報 特開2004−89806号公報
Therefore, in order to disable the trigger operation at the blocking position, the operation plate covering the trigger front surface is suspended from the nozzle cap, the liquid ejection passage is blocked while the operation plate covers the trigger front surface, and the nozzle cap is rotated. There is also known a trigger type liquid ejector that is operated through the operation plate (Patent Document 2).
Japanese Utility Model Publication No. 60-27482 JP 2004-89806 A

上記のようにノズルキャップから操作板を垂下させた場合は該操作板でノズルキャップを回動させることから該操作板がレバーの機能を果すこととなってトルクが大となり、よってノズルキャップが過剰に回動して液体噴出通路連通方向への回動を停止させるために設けた係合子を乗り越えるおそれがあった。   When the operation plate is suspended from the nozzle cap as described above, the nozzle cap is rotated by the operation plate, so that the operation plate functions as a lever, resulting in a large torque, and therefore the nozzle cap is excessive. There is a risk of overcoming the engaging element provided to stop the rotation in the direction of communication with the liquid ejection passage.

本発明はそのような欠点を除くため、上記係合部に代えて、又その係合部と共に、液体噴出通路開通方向へのノズルキャップの回動を阻止させる係合手段を設けて使い易く、又液体噴出の開始および停止を確実に行えるよう設けた。   In order to eliminate such drawbacks, the present invention is easy to use by providing an engaging means for preventing the nozzle cap from rotating in the liquid ejection passage opening direction in place of the engaging portion or together with the engaging portion. In addition, it was provided so that liquid ejection could be started and stopped reliably.

尚トリガー式液体噴出器は各種液体噴出用として用いられており、液体の洗浄剤や漂白剤噴出用としても用いられているが、pHが8を越えるアルカリ性のものや6未満の酸性のもの、特にpHが11を越える場合や3未満の場合、誤ってトリガーを引いたり予期せぬ事態でトリガーが引かれて内溶液が吐出され、身体等にかかって危険な状態を引き起こしたり不具合が発生する懸念があった。
本発明はそのような課題の解決も目的とする。
The trigger type liquid ejector is used for ejecting various liquids, and is also used for ejecting a liquid detergent or a bleaching agent. Especially when the pH exceeds 11 or less than 3, the trigger is accidentally pulled or the trigger is pulled due to an unexpected situation, and the internal solution is discharged, causing a dangerous state or malfunction on the body etc. There was concern.
The present invention also aims to solve such problems.

第1の手段として、噴出器本体1の前面上部から前方突出させた中心軸4付き射出筒5へノズルキャップ11を嵌合させ、該ノズルキャップから垂下してトリガー24前面を覆う操作板21を介して行うノズルキャップの正逆両方向回動で、射出筒の中心軸4とノズルキャップとがそれぞれ有する第1、第2液体噴出路7、18が操作板垂下状態で断絶し、操作板回動状態で連通するトリガー式液体噴出容器において、
上記操作板21を正方向へ回動させて上記両液体噴出路が連通したとき、互いに係合する第1係合子29と第2係合子30とを、トリガー上部の前面に突設した突部と、ノズルキャップ11の外周壁後部を切欠いて形成した切欠き面とで形成し
上記ノズルキャップ11を、ノズル孔付きのキャップ本体11aと、該キャップ本体の外周筒面へ回動不能に嵌着させた外周壁11bとで正面視ほぼ正三角形状に形成し、該外周壁外面の一角部19aが下方に、該一角部の向いの辺20aが水平状に位置する状態で上記一角部19aの後部から操作板21を垂下させ、該状態から操作板を正方向へ回動させて他角部19bと向い合う辺20bがノズルキャップ上面で水平状となったとき、両液体噴出路7、18が連通可能に形成し、
上記ノズルキャップ11を後面開口の多重筒として、第1液体噴出路7付き中心軸4外面へ嵌合させた第2液体噴出路18付き最内筒の外面と、該最内筒外面へ遊嵌させた射出筒5内面とに、上記第1、第2液体噴出路7、18が連通したときに係合する第1、第2係合突部27、28を付設した。
As a first means, a nozzle cap 11 is fitted to an injection cylinder 5 with a central shaft 4 projecting forward from the front upper part of the ejector body 1, and an operation plate 21 that hangs down from the nozzle cap and covers the front surface of the trigger 24 is provided. When the nozzle cap is rotated in both forward and reverse directions, the first and second liquid ejection passages 7 and 18 of the central axis 4 of the injection cylinder and the nozzle cap are disconnected while the operation plate is suspended, and the operation plate is rotated. In the trigger type liquid ejection container that communicates in the state,
When the operation plate 21 is rotated in the forward direction so that the two liquid ejection paths communicate with each other, the first engaging member 29 and the second engaging member 30 that are engaged with each other project from the front surface of the trigger upper portion. And a notch surface formed by notching the rear portion of the outer peripheral wall of the nozzle cap 11 ,
The nozzle cap 11 is formed in a substantially equilateral triangular shape when viewed from the front by a cap main body 11a with a nozzle hole and an outer peripheral wall 11b non-rotatably fitted to the outer peripheral cylindrical surface of the cap main body. The operation plate 21 is suspended from the rear portion of the corner 19a with the corner 19a facing downward and the side 20a facing the corner positioned horizontally, and the operation plate is rotated in the forward direction from this state. When the side 20b facing the other corner 19b becomes horizontal on the upper surface of the nozzle cap, both the liquid ejection paths 7 and 18 are formed so as to communicate with each other,
The nozzle cap 11 is formed as a multiple cylinder with a rear opening, and the outer surface of the innermost cylinder with the second liquid ejection path 18 fitted to the outer surface of the central shaft 4 with the first liquid ejection path 7 and loosely fitted to the outer surface of the innermost cylinder. First and second engaging projections 27 and 28 that are engaged when the first and second liquid ejection passages 7 and 18 communicate with each other are provided on the inner surface of the injection cylinder 5 that has been made to move.

の手段として,上記第1の手段を有し、かつpHが8を超えるか、もしくはpHが6未満の液体洗浄剤又は液体漂白剤を噴出用液体とした。 As a second means, a liquid cleaning agent or a liquid bleaching agent having the first means and having a pH of more than 8 or a pH of less than 6 was used as the ejection liquid.

第1の手段のようにすることで、トリガー式液体噴出器使用者が第1、第2係合子29、30の係合による、液体噴出通路連通方向への、つまり正方向へのノズルキャップ回動完了に気付き易く、よってそのノズルキャップの過剰回動を防ぐことが出来る。 By using the first means , the trigger type liquid ejector user can rotate the nozzle cap in the liquid ejection passage communication direction, that is, in the positive direction by the engagement of the first and second engagement elements 29 and 30. It is easy to notice the completion of the movement, and therefore it is possible to prevent the nozzle cap from excessively rotating.

又それ等第1、第2係合子29,30 はトリガーおよびノズルキャップ外面へ形成するから大きくしてもノズルキャップ内等に設ける場合と異って他物の邪魔となることがない。   Also, since the first and second engaging members 29 and 30 are formed on the outer surface of the trigger and the nozzle cap, even if they are large, they do not interfere with other objects unlike the case where they are provided in the nozzle cap or the like.

更に、外見上液体噴出通路連通位置と遮断位置とを見分け易く、よって操作板21を介して行うノズルキャップの過剰な回動を未然に防止できる。 In addition, it is easy to distinguish between the liquid ejection passage communication position and the blocking position in appearance, so that excessive rotation of the nozzle cap performed through the operation plate 21 can be prevented beforehand.

また、正方向へのノズルキャップの過剰回動阻止手段を二重に行うことができると共に、第1、第2係合突部27、28はノズルキャップの最内筒外面と射出筒5の内面とに付設するから、ノズルキャップに設ける第1係合突部27移動路としての空間をノズルキャップ内に位置させることが出来、よって該空間内へ埃等が入ってノズルキャップ回動の妨げとなることがない。 Further , the means for preventing excessive rotation of the nozzle cap in the forward direction can be doubled, and the first and second engaging projections 27 and 28 are provided on the outer surface of the innermost cylinder of the nozzle cap and the inner surface of the injection cylinder 5. Therefore, the space as the movement path of the first engaging protrusion 27 provided in the nozzle cap can be positioned in the nozzle cap, and thus dust or the like enters the space and prevents the nozzle cap from rotating. Never become.

第2の手段のようにすることで、pHが8を超えるか、もしくはpHが6未満の液体洗浄剤又は液体漂白剤噴出用のトリガー式液体噴出器としても安全に使用することが出来る。
By using the second means , it can be safely used as a trigger type liquid ejector for ejecting a liquid detergent or liquid bleach having a pH of more than 8 or less than 6.

以下図面について説明する。まず公知の部分について説明すると、1はトリガー式液体噴出器で該噴出器の上部内に、横設した射出管2前端へ仕切板3付きの射出部材2a を嵌着させ、該仕切板中心から中心軸4を、かつ該中心軸を囲んで射出筒5をそれぞれ前方突出し、その中心軸と射出筒との間の仕切板部分には透孔6を穿設して上記射出管内と射出筒内とを連通させている。中心軸4の前部外面へは第1液体噴出路7としての溝を母線方向へ穿設し、又中心軸前面へはスピン溝8を設けている。   The drawings will be described below. First, a known part will be described. 1 is a trigger type liquid ejector, and an injection member 2a with a partition plate 3 is fitted to the front end of a horizontal injection tube 2 in the upper portion of the ejector, and from the center of the partition plate. The central axis 4 and surrounding the central axis project the injection cylinder 5 forward, and a through hole 6 is formed in the partition plate portion between the central axis and the injection cylinder so that the inside of the injection pipe and the injection cylinder And communicate with each other. A groove as a first liquid ejection path 7 is formed in the front surface of the central shaft 4 in the generatrix direction, and a spin groove 8 is provided on the front surface of the central shaft 4.

11はノズルキャップで、図示例にあっては該キャップをノズルキャップ本体11aと該ノズルキャップ本体外周面へ嵌着させた外周壁11bとで形成しており、そのキャップ本体は中心にノズル孔12を有する前壁板13外周から前方へ前筒14を、かつ後方へ後筒15を、それぞれ突出させており、前筒前端からは上記後筒15を囲んで折返し筒16を後方突出させている。又上記ノズル孔を囲んで前壁板中央部後面からは内筒17を後方突出させて中心軸4外面へ回動可能に嵌合させ、該内筒の後半内面へは第2液体噴出路18としての溝を穿設している。又内筒17と上記後筒15との間からは短く設けた中間筒32を後方突出させ、該中間筒を既述射出筒5の前部内面へ嵌合させている。   Reference numeral 11 denotes a nozzle cap. In the illustrated example, the cap is formed by a nozzle cap main body 11a and an outer peripheral wall 11b fitted to the outer peripheral surface of the nozzle cap main body. The front cylinder 14 has a front cylinder 14 projecting forward and a rear cylinder 15 projecting rearward from the outer periphery, and the folded cylinder 16 projects rearward from the front cylinder front end so as to surround the rear cylinder 15. . Further, the inner cylinder 17 is protruded rearward from the rear surface of the central portion of the front wall plate so as to surround the nozzle hole, and is rotatably fitted to the outer surface of the central shaft 4. As a hole is drilled. Further, a short intermediate cylinder 32 is protruded rearward from between the inner cylinder 17 and the rear cylinder 15, and the intermediate cylinder is fitted to the front inner surface of the injection cylinder 5.

上記ノズルキャップ本体11a と外周壁11b とは、図2が示すように正面からみて、角先端部を面取りし、かつ各辺部を多少弯曲させたほぼ正三角形状としており、外周壁11b の一角部19aを下方に、該一角部と向い合う辺20aをほぼ水平とした状態で、上記一角部19aから操作板21を垂下させている。尚該操作板の正方向回動側の側面から係止板22をトリガー側面外方を通って後方突出させ、その後端面をシリンダ23の前端面へ係合し、そのため操作板21を後方へ移動させることが出来ないよう設けている。   As shown in FIG. 2, the nozzle cap body 11a and the outer peripheral wall 11b have a substantially equilateral triangular shape with chamfered corner tips and slightly curved sides, as seen from the front. The operation plate 21 is suspended from the corner 19a with the portion 19a downward and the side 20a facing the corner almost horizontal. The locking plate 22 is protruded rearward from the side of the operation plate on the positive rotation side, passing through the trigger side surface, and the rear end surface is engaged with the front end surface of the cylinder 23, so that the operation plate 21 is moved rearward. It is set up so that it cannot be made.

24は上部を、二又状に分岐させたトリガーでそれ等両上端部を射出管前部の両側へ枢着させており、そのトリガー上部から後方突出させた棒25後端を噴出器本体が有するシリンダ23内から前方付勢させて前方突出させたプランジャ26前面の凹部内へ係合させることで、トリガーは前方付勢されている。尚該トリガー24は、図8が示すようにトリガー本体外面へ長く設けたカバー24aを嵌着させてレバー機能を高めることもあり、このようにトリガーは二体で形成してもよい。   24 is a trigger whose upper part is bifurcated, and both upper ends thereof are pivotally attached to both sides of the front part of the injection pipe. The trigger is forward-biased by being engaged in a concave portion on the front surface of the plunger 26 that is forwardly urged from within the cylinder 23 and protruded forward. As shown in FIG. 8, the trigger 24 may be provided with a long cover 24a on the outer surface of the trigger body to enhance the lever function. Thus, the trigger may be formed of two bodies.

上記操作板21が図1、図2のように垂下して、トリガー24前面を覆う状態で既述第1、第2液体噴出通路7,18 は遮断され、それ等両通路が連通する図3の位置まで操作板21を正方向(図示例では反時計回り)へ回して他角部19b が下方へ位置したとき、該他角部と向い合う辺20bがほぼ水平となる。   The operation plate 21 hangs down as shown in FIGS. 1 and 2 and covers the front surface of the trigger 24, so that the first and second liquid ejection passages 7 and 18 are blocked, and these passages communicate with each other. When the operation plate 21 is rotated in the forward direction (counterclockwise in the illustrated example) to the position of (2) and the other corner portion 19b is positioned downward, the side 20b facing the other corner portion becomes substantially horizontal.

本発明にあっては、図5が示すように上記両通路連通状態で係合する第1係合子29と第2係合子30とを、トリガー24の上部前面と、ノズルキャップ11の外周壁11b の後部とに設けた。図示例において第2係合子30は図5、図6が示すように外周壁11b の他角部19b 側面を切欠きし、該切欠き面で形成した。第2係合子30はノズルキャップ11回動時に該ノズルキャップ後部に形成された弧状路31を通ることとなり、該弧状路は、図5が示すように角部においては該角部を切欠きし、又辺部においては両側を切欠き孔として辺部外方に形成している。   In the present invention, as shown in FIG. 5, the first engagement element 29 and the second engagement element 30 that are engaged in the above-mentioned two-passage communication state are connected to the upper front surface of the trigger 24 and the outer peripheral wall 11 b of the nozzle cap 11. And provided at the rear. In the illustrated example, the second engagement element 30 is formed by notching the side surface of the other corner portion 19b of the outer peripheral wall 11b as shown in FIGS. The second engagement element 30 passes through an arcuate path 31 formed at the rear part of the nozzle cap 11 when the nozzle cap 11 is rotated, and the arcuate path is cut out at the corner as shown in FIG. Moreover, in the side part, both sides are formed as a notch hole outside the side part.

又図3が示すように既述射出筒内面と該射出筒内面へ遊嵌させた内筒17の外面とには、上記両通路連通状態で互いに係合する第1、第2係合突部27,28 を付設した。尚これ等両係合突部は必ずしも必要ではない。
Further, as shown in FIG. 3, the first and second engagement protrusions that engage with each other in the above-mentioned passage communication state are formed on the inner surface of the injection cylinder 5 and the outer surface of the inner cylinder 17 that is loosely fitted to the inner surface of the injection cylinder. Parts 27 and 28 were added. These two engaging protrusions are not always necessary.

本発明は上記構成とするもので、上記実施形態にあっては図1、図2が示す操作板21垂下状態から図3のように他角部19b が下方へ、又他辺部20b が上方へ水平に位置する状態まで回動させたとき、第1、第2液体噴出路7,18 が連通し、このとき第1係合突部27と第2係合突部28とが係合し、又該係合と同時に図5が示すように第1係合子29と第2係合子30とが係合してノズルキャップ11の過剰回動を防止する。よって該状態からトリガー操作で液体噴出をさせることが出来る。   The present invention is configured as described above. In the above embodiment, the other corner portion 19b is downward and the other side portion 20b is upward as shown in FIG. 3 from the suspended state of the operation plate 21 shown in FIGS. When the first and second liquid ejection paths 7 and 18 are communicated with each other, the first engagement protrusion 27 and the second engagement protrusion 28 are engaged with each other. Simultaneously with the engagement, as shown in FIG. 5, the first engagement element 29 and the second engagement element 30 are engaged to prevent the nozzle cap 11 from excessively rotating. Therefore, the liquid can be ejected from the state by a trigger operation.

液体噴出後に操作板21を復帰させれば該操作板から後方突出する係止板22が図7のようにトリガー側面へ接して復帰方向への過剰回動を停止させ、又係止板後端面がシリンダ23前端面へ接して操作板21の後方押込みを不能とするものである。   When the operation plate 21 is returned after the liquid is ejected, the locking plate 22 protruding rearward from the operation plate contacts the side of the trigger as shown in FIG. 7 to stop the excessive rotation in the return direction, and the rear end surface of the locking plate Is in contact with the front end surface of the cylinder 23 and makes it impossible to push the operation plate 21 backward.
