【０００１】
【発明の属する技術分野】
本発明はトリガー式液体噴出器に関する。
【０００２】
【従来の技術】
トリガー式液体噴出器として、例えば、容器体口頚部に嵌合させた装着キャップと、該キャップ上方に嵌着固定するとともに、装着キャップ上端から起立した縦筒の中間部からシリンダを、その上部からは射出筒をそれぞれ前方へ突出してなるポンプ本体と、上記射出筒先端に嵌着させたノズルヘッドと、上記射出筒前部から前後揺動可能に垂設するとともに、上記シリンダ内に前方付勢状態で嵌合させたプランジャの先端部を押し込み可能に連係させたトリガーとを備え、該トリガーの操作により内蔵ポンプ機構の作用で容器体内の液を吸い上げてノズルヘッドの噴出口より噴出する如く構成したものが知られている。
【０００３】
また、この種噴出器では、一般に、不用意なトリガーの操作による液の漏出、或いは商品陳列時に於ける悪戯の防止を図るために、射出筒前端に設けたノズル嵌合筒にノズルヘッドを回動可能に設けるとともに、両者間にノズルヘッドを回動させることにより液流路の連通が遮断され、元の状態に戻せば連通する開閉機構を設けている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記した開閉機構を設けたものにあっても、トリガーはプランジャを介して液圧により押し込み不能に係止されているため、液流路閉塞状態のままで度々トリガーを引き寄せると、プランジャの若干の押し込みが可能となり、シリンダ内の異常な高圧化で吐出弁を通って、吐出弁下流の射出筒前方部分内に高圧液体が溜まることがあり、このようになるとノズルヘッドを液流路連通位置まで回した時、その射出筒前方部分内に溜まっていた高圧液体が、トリガー操作を行わなくてもノズル孔から噴出する不都合が生じたり、また、トリガーを強く引き寄せると、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虞もあった。
【０００５】
本発明は上記した点に鑑みなされたもので、不使用時等にトリガー操作を確実に防止して上記した不都合を解消することができ、また、使用時には取り扱いが便利であり、その構造も簡単な優れたトリガー式液体噴出器を提案するものである。
【０００６】
【課題を解決するための手段】
第１の手段として、以下の通り構成した。即ち、容器体口頚部３に嵌合させた装着キャップ４と、該キャップ上端から起立して上部から射出筒７を前方へ突出してなるポンプ本体９と、射出筒７前部から前後揺動可能に垂設したトリガー10と、射出筒７先端に回動可能に嵌着させたノズルヘッド11とを備え、トリガーの操作により容器体内の液を吸い上げてノズルヘッドの噴出口16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、ノズルヘッド11からトリガー10前面に沿って垂下するとともに、前面に後方引き寄せ防止突部14を突設し、且つ、側面からトリガー側面に当接係止させた係止板部15を後方突設してなる揺動被覆板13を、ノズルヘッド11の回動に伴う回動が可能に設けてなる如く構成した。
【０００７】
第２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、上記揺動被覆板13が、噴出口16を開口してノズルヘッド11の外周面に嵌着したノズルヘッドカバー17からトリガー10前面に沿って垂下してなる揺動被覆板13である如く構成した。
【０００８】
第３の手段として、以下の通り構成した。即ち、前記第１の手段又は第２の手段のいずれかの手段に於いて、上記係止板部15に代えて、トリガー10側面から裏面に亘り嵌合係止するとともに、トリガー側板10b 後端縁内面に離脱可能に係合する係合突起18を突設してなる係止板部15A を設けた。
【０００９】
第４の手段として、以下の通り構成した。即ち、前記第１の手段乃至第３の手段のいずれかの手段に於いて、上記ノズルヘッド11の回動により液流路の開閉切り換えが可能に構成するとともに、ノズルヘッド11の液流路遮断状態で揺動被覆板13の係止板部15，15A がトリガーに当接係止した状態となる如く構成した。
【００１０】
【発明の実施の形態】
以下、本発明の実施例の形態を図面を参照して説明する。
【００１１】
本発明のトリガー式液体噴出器は、容器体口頚部に嵌合させる装着キャップと、装着キャップ上端から起立して上部から射出筒を前方へ突出してなるポンプ本体と、射出筒前部から揺動可能に垂設したトリガーと、射出筒先端部に回動可能に嵌着させたノズルヘッドとを備え、トリガーの操作により容器体内の液を吸い上げてノズルヘッドの噴出口より噴出する如く構成した公知のポンプ機構を備えたものである。
【００１２】
図示例では、容器体２の口頚部３に嵌合させる装着キャップ４と、装着キャップ上方に嵌着固定するとともに、装着キャップ上端から起立した縦筒５の中間部からシリンダ６を、その上部からは射出筒７をそれぞれ前方へ突出し、これら縦筒５、シリンダ６、射出筒７の上面、両側面、後面をカバー８で被覆してなるポンプ本体９と、射出筒７前部から前後揺動可能に垂設したトリガー10と、射出筒７先端部に回動可能に嵌着させたノズルヘッド11とを備えている。
【００１３】
また、シリンダ６内に押し込み可能に嵌合させたプランジャ12の先端を、トリガー10の上部に連係させて、トリガー10と内蔵ポンプ機構とを連係させている。また、射出筒７前端部には図示しないノズル嵌合筒を嵌着し、このノズル嵌合筒を介してノズルヘッド11を回動可能に嵌合させており、ノズルヘッド11とノズル嵌合筒には、ノズルヘッド11の回動により液流路の開閉切り換えが可能な公知の開閉機構を備えているものが採用できるが、ノズルヘッド11を単に射出筒７先端部に回動可能に嵌着させた構造のものであっても良い。更に、トリガー10は、縦長の前板10a 両側から後方へ一対の側板10b を延設して構成しており、各側板上端部を前板より上方へ突設し、該突設部分を射出筒７前部両側のカバー８内面にそれぞれ枢着して前後方向の揺動が可能に構成している。
【００１４】
本発明では、上記したこの種の噴出器に於いて、不使用時にトリガー10の不用意な引き込みを確実に防止する目的で揺動被覆板を設けている。
図１に示す実施例に於いて揺動被覆板13は、ノズルヘッド11からトリガー10前面に沿って垂下するとともに、前面に後方引き寄せ防止突部14を突設し、且つ、側面からトリガー側面に当接係止させた係止板部15を後方突設し、ノズルヘッド11の回動に伴う回動が可能に設けている。従って、揺動被覆板13がトリガー10前方に位置する場合には、トリガー10を後方へ引くことができず、その結果、液の不用意な漏出を防止できる。また、揺動被覆板13を側方へ回動させるとトリガー10の引き込みが可能となり、液の噴出が可能となる。
【００１５】
この際、トリガー10とノズル嵌合筒との間に上記した開閉機構を備えたものを使用する場合には、液流路遮断状態で揺動被覆板13の係止板部15がトリガー10に当接係止した状態となる如く構成する。従って、この状態では、液流路の遮断と、揺動被覆板13によるトリガー10の後方への引き込み防止との二重ロック構造になる。
【００１６】
後方引き寄せ防止突部14は、指先を掛け、更に無理やり引こうとすると違和感を覚える如き形態の突部で、後方への引き込みを触覚的に防止させるためのもので、例えば、図示例の如き、揺動被覆板13前面中央を縦断し、側面から見て前縁が縦波形をした突条形態のものが採用でき、また、図示しないが、揺動被覆板13前面中央を縦断し、側面から見て縦長長方形状のものが採用できる。
【００１７】
また、本実施例では、ノズルヘッド11の外周面に前面噴出口16部分を開口してノズルヘッドカバー17を嵌着しており、該ヘッドカバー17の下面より揺動被覆板13を一体に延設しているが、揺動被覆板13は、ノズルヘッドカバー17から一体に延設する場合に限らず、射出筒７に回動可能に嵌着させたノズルヘッド11から直接延設しても良い。また、上記係止板部15は、上記図１〜図３に示す実施例のものに限らず、トリガー10の側面から裏面に亘り嵌合係止する横断面鉤形をなすものであってもよい。
【００１８】
図４は本発明の他の実施例を示すもので、本実施例では、図１の実施例に於いて上記係止板部15に代えて、トリガー10の側面から裏面に亘り嵌合係止するとともに、トリガー側板10b 後端縁内面に離脱可能に係合する係合突起18を突設してなる係止板部15A を設けている。この場合も揺動被覆板13はノズルヘッドカバー17の下面より一体に延設しても良く、ノズルヘッド11から直接一体に延設しても良い。また、上記開閉機構を備えたものであっても、単にノズルヘッドを回動可能に設けたものであっても良い。
尚、上記各部材は全て合成樹脂により形成することが可能である。
【００１９】
【発明の効果】
以上説明した如く本発明の液体注出容器は、既述構成としたことにより、不使用時には、揺動被覆板13によりトリガー10の引き込みを確実に防止できて不用意な液の漏出を防止でき、また、使用時には揺動被覆板を側方に回動させるだけで液の注出が可能となるとともに、使用後はその係止板部15をトリガーに当接係止させるまで揺動被覆板を逆に回動させれば元の状態に戻るため取り扱いも極めて便利である。また、係止板部の存在で、使用後の揺動被覆板を元のトリガー前面位置に正確に戻すのを容易に行える。
【００２０】
また、噴出口16を開口してノズルヘッド11の外周面に嵌着したノズルヘッドカバー17からトリガー10前面に沿って垂下してなる揺動被覆板13を設けたものにあっては、揺動被覆板の取り付けが容易で、既存のトリガー式液体噴出器を利用して製造することができる利点を兼ね備える。
【００２１】
また、トリガー側面から裏面に亘り嵌合係止するとともに、トリガー側壁後端縁内面に離脱可能に係合する係合突起18を突設してなる係止板部15A を設けたものにあっては、外力等により簡単に揺動被覆板が回動することを防止できるものである。
【００２２】
また、ノズルヘッド11の回動により液流路の開閉切り換えが可能に構成するとともに、ノズルヘッドの液流路遮断状態で揺動被覆板の係止板部がトリガーに当接係止した状態になる如く構成したものにあっては、揺動被覆板のトリガーの引き込みの防止と、ノズル部分の液流路遮断との二重ロック構造となり、また、液流路の内圧が高まることはなく、液流路の遮断を解除した際の液の暴発やノズルヘッドが外れる等の不都合を防止できる。

However, even with the above-described opening / closing mechanism, the trigger is locked so that it cannot be pushed in by hydraulic pressure via the plunger. Slight push-in is possible, and high pressure liquid may accumulate in the front part of the injection cylinder downstream of the discharge valve due to abnormally high pressure in the cylinder. In this case, the nozzle head is connected to the liquid flow path. The high-pressure liquid that has accumulated in the front part of the injection cylinder when it is turned to the position will not be able to be ejected from the nozzle hole without trigger operation. There is also a possibility that the nozzle head may come off from the nozzle fitting cylinder due to the conversion.

The pump mechanism is provided.
[0012]
In the illustrated example, the mounting cap 4 to be fitted to the mouth / neck portion 3 of the container body 2 and the upper portion of the mounting cap are fitted and fixed to the upper portion of the mounting cap 4, and the cylinder 6 is inserted from the upper portion of the vertical cylinder 5 upright from the upper end of the mounting cap. Each protrudes forward from the injection cylinder 7, and the vertical cylinder 5, the cylinder 6, the pump main body 9 in which the upper surface, both side surfaces, and the rear surface of the injection cylinder 7 are covered with the cover 8, and swings back and forth from the front of the injection cylinder 7. A trigger 10 that is vertically suspended and a nozzle head 11 that is rotatably fitted to the tip of the injection cylinder 7 are provided.
[0013]
Further, the tip of the plunger 12 fitted so as to be able to be pushed into the cylinder 6 is linked to the upper part of the trigger 10, and the trigger 10 and the built-in pump mechanism are linked. A nozzle fitting cylinder (not shown) is fitted to the front end portion of the injection cylinder 7, and the nozzle head 11 is rotatably fitted through the nozzle fitting cylinder. The nozzle head 11 and the nozzle fitting cylinder In this case, a known opening / closing mechanism capable of switching the opening and closing of the liquid flow path by the rotation of the nozzle head 11 can be used. It may be of the structure made. Further, the trigger 10 is configured by extending a pair of side plates 10b from both sides of the longitudinal front plate 10a to the rear, projecting the upper end of each side plate upward from the front plate, and projecting the projected portion into the injection cylinder. 7 The front and rear covers 8 are pivotally attached to the inner surfaces of the covers 8 so as to be swingable in the front-rear direction.
[0014]
In the present invention, the above-described ejector is provided with a swing covering plate for the purpose of surely preventing inadvertent pulling of the trigger 10 when not in use.
In the embodiment shown in FIG. 1, the swing covering plate 13 hangs down from the nozzle head 11 along the front surface of the trigger 10, has a rear pulling preventing projection 14 on the front surface, and extends from the side surface to the trigger side surface. The locking plate portion 15 that is abutted and locked is provided so as to protrude rearward so that the nozzle head 11 can be rotated as the nozzle head 11 rotates. Therefore, when the swing covering plate 13 is positioned in front of the trigger 10, the trigger 10 cannot be pulled backward, and as a result, inadvertent leakage of the liquid can be prevented. Further, when the swing covering plate 13 is rotated to the side, the trigger 10 can be pulled in, and the liquid can be ejected.
[0015]
At this time, when using the above-described opening / closing mechanism between the trigger 10 and the nozzle fitting cylinder, the locking plate portion 15 of the swing covering plate 13 is attached to the trigger 10 in the liquid flow path shut-off state. It is configured so as to be in a contact-locked state. Therefore, in this state, a double lock structure in which the liquid flow path is blocked and the trigger 10 is prevented from being pulled back by the swing covering plate 13 is obtained.
[0016]
The rear pulling prevention protrusion 14 is a protrusion of a form that feels uncomfortable when the fingertip is hung and further forcibly pulled, and for tactile prevention of pulling backward, for example, as shown in the example, The front surface of the rocking cover plate 13 can be vertically cut, and the front edge of the ridge shape can be adopted when viewed from the side. A vertically long rectangular shape can be used.
[0017]
Further, in this embodiment, the nozzle head cover 17 is fitted by opening the front jet port 16 portion on the outer peripheral surface of the nozzle head 11, and the swing covering plate 13 is integrally extended from the lower surface of the head cover 17. However, the oscillating cover plate 13 is not limited to being integrally extended from the nozzle head cover 17 but may be directly extended from the nozzle head 11 that is rotatably fitted to the injection cylinder 7. Further, the locking plate portion 15 is not limited to the embodiment shown in FIGS. 1 to 3, and may have a cross-sectional shape that fits and locks from the side surface to the back surface of the trigger 10.

At the same time, a locking plate portion 15A is provided in which an engagement projection 18 is provided projectingly engaged with the inner surface of the rear edge of the trigger side plate 10b. Also in this case, the swing covering plate 13 may be integrally extended from the lower surface of the nozzle head cover 17, or may be directly extended from the nozzle head 11. Moreover, even if the opening / closing mechanism is provided, the nozzle head may be simply provided so as to be rotatable.
It should be noted that all of the above members can be made of synthetic resin.
[0019]
【The invention's effect】
As described above, since the liquid dispensing container of the present invention has the above-described configuration, when not in use, the swing cover plate 13 can reliably prevent the trigger 10 from being pulled in and prevent inadvertent liquid leakage. In use, the liquid can be dispensed by simply rotating the rocking cover plate to the side, and after use, the rocking cover plate is held until the locking plate portion 15 is brought into contact with and locked to the trigger. If it is rotated in reverse, it will return to its original state, so handling is extremely convenient. Further, the presence of the locking plate portion makes it easy to accurately return the used swing covering plate to the original trigger front surface position.
[0020]
In addition, in the case of providing a rocking covering plate 13 that hangs along the front surface of the trigger 10 from the nozzle head cover 17 that opens the jet nozzle 16 and is fitted to the outer peripheral surface of the nozzle head 11, the rocking covering The plate can be easily attached, and has the advantage that it can be manufactured using an existing trigger type liquid ejector.
[0021]
