【発明が解決しようとする課題】
上記前者の公知例にあっては、不用意にトリガーを引寄せても射出筒前端から液体を噴出するから、このような不用意な液体噴出を防止するための安全装置を設けることが望まれ、また後者公知例はそのような安全装置として設けられたが、該後者公知例にあってもその安全装置を施した状態でトリガーを無理に引寄せると、僅かにトリガーおよびプランジャが後退、前進することで容器体内液体が吸込まれ、その結果吸込み弁から上記射出筒前部とノズルキャップとが形成する液体通路開閉機構までの液体流入部分内へ過剰に液体が流入することとなり、該状態からノズルキャップを回して上記開閉機構を開くと、上記過剰に充填されていた液体が液体噴出孔から噴出するおそれがあった。
本発明はトリガー操作を不能とする安全装置を設けることで、上記のような不用意な液体噴出を防止できるよう設けたものである。
【０００５】
【課題を解決するための手段】
第１の手段として、容器体口頸部へ嵌合させた装着筒１内から主筒１ａを起立し、該主筒前面からシリンダ２を、かつ主筒１ａ上端から射出筒３を、それぞれ前方突設し、又射出筒３前部に枢着させて垂設したトリガー４の上方後部に、シリンダ２内へ嵌合させたプランジャ５前端部を連結し、かつトリガー４を前方付勢させ、トリガーの前後方向揺動で容器体内液体をシリンダ２内へ吸込み、かつ該シリンダ内液体を射出筒３前端から噴出可能に設けたトリガー式液体噴出容器において、

上記ストッパ部材１２は、ストッパ板１１後端がシリンダ２下部前端へ係合してトリガー４の後方への引寄せを不能にする係合位置と、ストッパ板１１後端がシリンダ２から下方へ離脱してトリガーの後方への引寄せを可能にする非係合位置とを有する。
【０００６】
第２の手段として、容器体口頸部へ嵌合させた装着筒１内から主筒１ａを起立し、該主筒前面からシリンダ２を、かつ主筒１ａ上端から射出筒３を、それぞれ前方突設し、又射出筒前部に枢着させて垂設したトリガー２０の上方後部に、シリンダ内へ嵌合させたプランジャー５前端部を連結し、かつトリガーを前方付勢させ、トリガーの前後方向揺動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筒前端から噴出可能に設けたトリガー式液体噴出容器において、上記トリガー２０を前壁２１の左右から側壁２２を後方突出する横断面コ字形状としておき、上記トリガー２０の左右両側壁２２間へ上下動自在に嵌合させた摺動板２３上部後面からストッパ板２６を後方突出してストッパ部材２９を形成し、該ストッパ部材のトリガーに対する上動でストッパ板２６後端がシリンダ２下部前端へ係合可能に形成し、更に上記トリガー２０の左右両側壁２２内面と摺動板２３の左右方向側面との一方に係合突起３０を、他方に上下面閉塞の上下方向への長溝３１を形成し、該長溝内へ係合突起を上下動自在に嵌合させ、上記ストッパ部材２９は、ストッパ板２６後端がシリンダ下部前端へ係合してトリガーの後方への引寄せを不能にする係合位置と、ストッパ板２６がシリンダから下方へ離脱してトリガーの後方への引寄せを可能にする非係合位置とを有し、上記長溝３１の一部を、上記係合突起３０が強制通過可能な溝幅を有する幅狭部として、この幅狭部を係合突起３０が通過することで、ストッパ部材２９が上記係合位置から非係合位置へ移行することを特徴とする。

【０００７】

【０００９】
【発明の実施の形態】
以下、本発明に係るトリガー式液体噴出容器の実施形態を図面を参照しながら説明する。
まず、公知のトリガー式液体噴出容器について簡単に説明すると、図示しない容器体口頸部へ嵌合させた装着筒１内から主筒１ａを起立し、該主筒前面からシリンダ２を、かつ主筒１ａ上端から射出筒３を、それぞれ前方突出し、また射出筒３前部に枢着させて垂設したトリガー４の上部後側に、シリンダ２内へ嵌合させたプランジャ５前端部を連結し、トリガー４の前後方向揺動で容器体内液体をシリンダ２内へ吸込み、かつ該シリンダ内液体を射出筒３前端から噴出可能に設けている。
なお、トリガー４は、シリンダ２内に設けたプランジャ５付勢用のバネによりプランジャを介して、又は主筒１ａ等のトリガー４以外の部材に一端を取り付けたバネにより前方付勢させる。
【００１０】
図１乃至図４に示す請求項１記載の発明では、トリガー４を前壁６の左右から側壁７を後方突出する横断面コ字形状として、それら左右両側壁上部外面に上下方向へ伸びる突条である係合突部８を、前後方向に所定の間隔をおいて複数形成する。また前壁６前面に、係合突部８下端とほぼ等しい高さに位置させて上向き段部９を形成する。
【００１１】
さらにトリガー４外面へ上下動自在に嵌合させた矩形状の枠体１０後部からストッパ板１１を後方突設してストッパ部材１２を形成する。ストッパ板１１後端面はシリンダ下部前端面へ係合可能になっており、またストッパ板１１のこの係合位置において、枠体１０下端は係合突条８上端へ係合する。
【００１２】
なお、請求項３記載のように、射出筒３前端部へ回動可能に液体噴出孔を有するノズルキャップ１３を嵌合させ、これら嵌合部に、射出筒３に対するノズルキャップ１３の回動で射出筒３が有する射出筒孔と液体噴出孔とを連通させ、又遮断させることが可能な液体通路開閉機構を設けることも可能である。この液体通路開閉機構は、例えば実開昭６２−１８７６６５号に記載されているように公知である。
図中１４は主筒１ａに連通する吸込みパイプで、その下端は容器体（図示せず）底部に達する。
【００１３】
次に本実施形態の作用について説明する。ストッパ部材１２がトリガー４に対して上限位置に位置する場合には、図１及び図２に示すように、ストッパ板１１後端面がシリンダ２下部前端面へ係合しており、従って、トリガー４の後方への引寄せが不能である。なお、この状態では枠体１０下端が係合突部８上端へ係合しているため、ストッパ板１１後端がシリンダ２前端から下方へ離脱することが防止される。
【００１４】
トリガー４の後方への引寄せを可能にするためには、係合突部８上端を乗り越えさせて枠体１０を下降させて、ストッパ板１１をシリンダ２から下方へ離脱させればよい。なお、この状態では枠体１０の前下端は上向き段部９に係合し、かつ枠体１０の左右両内面は係合突部８へ乗り上がった状態にある。
【００１５】
なお、図示しない液体通路開閉機構により射出筒３の射出筒孔とノズルキャップ１３の液体噴出孔とを遮断させることも可能であるが、この場合でもトリガー４を僅かではあるが前後へ揺動させることも不可能ではなく、仮にこの液体通路開閉機構による遮断状態でトリガー４を揺動させると過剰充填が生じ、ここで液体噴出孔と射出筒孔とを連通させて遮断を解除すると液体が噴出するという不具合が生ずるが、上記ストッパ部材１２によりトリガー４を引寄せ不能にしておけばこのような事態を未然に防止することができる。
【００１６】
図５及び図６は請求項２記載のトリガー式液体噴出容器を示すもので、トリガー２０は前壁２１の左右から側壁２２を後方突出する横断面コ字形状に形成する。また、トリガーの左右両側壁２２間へ上下動自在に嵌合させた左右一対の摺動板２３間上面を閉塞する頂板２４を両側壁２２後方へ延出させると共に、その延出させた頂板２４部分の左右両側から短板２５を垂下して、これら頂板２４と短板２５とでストッパ板２６を形成し、さらに両摺動板２３間の前面を閉塞する前板２７をトリガー前壁２１へ上下動自在に接触させると共に、両摺動板２３下面を底板２８で閉塞してストッパ部材２９を形成し、該ストッパ部材のトリガー２０に対する上動でストッパ板２６後端がシリンダ下部前端へ係合可能に形成する。
【００１７】
さらにトリガー２０の左右両側壁２２内面から係合ピン３０を左右方向内方へ突設すると共に、左右両摺動板２３に上下面閉塞の上下方向への長溝３１を形成し、該長溝内へ係合ピン３０を上下動自在に嵌合させる。
これら係合ピン３０と長溝３１とは上記とは逆に、係合ピン３０を摺動板２３に、また長溝３１をトリガー側壁２２に形成することもできる。
なお、請求項４記載のように、長溝３１の前後両側面下部から突起３２を突設して、係合ピン３０が強制通過可能な溝幅に形成することが好ましい。
【００１８】
次に本実施形態の作用について説明する。
トリガー２０の後方への引寄せを不能にするためには、図５に示すように、ストッパ部材２９をトリガー２０に対して上動させて、ストッパ板２６後端面をシリンダ２下部前端面へ係合させればよい。
【００１９】
長溝３１に突起３２を形成した請求項４では、ストッパ部材２９を上動させると、係合ピン３０が相対的に下降して突起３２上面へ係合するが、ここからさらにストッパ部材２９を上動させると、係合ピン３０が前後両突起３２間を通過して突起３２下面へ係合する。したがってストッパ板２６後端面がシリンダ２前端面から離脱することが確実に防止される。
トリガー２０の後方への引寄せを可能にするためには、ストッパ部材２９を下降させてストッパ板２６をシリンダ２から下方へ離脱させればよい。
【００２０】
【発明の効果】
請求項１及び２記載のトリガー式液体噴出容器は、トリガーの後方への引寄せを不能にするストッパ部材を設けたので、不使用時におけるトリガーの後方への引寄せを不能とすることができ、このため子供の悪戯等本来の目的以外の噴出防止が図れる。
【００２１】
請求項３記載のトリガー式液体噴出容器は、トリガーの後方への引寄せを不能にすることができるため、液体通路開閉機構による液体噴出孔と射出筒孔との遮断後におけるトリガーの僅かの揺動によって生ずる過剰充填に起因する不測の噴出といった事態を未然に防止することができる。
【００２２】
請求項２記載のトリガー式液体噴出容器は、長溝下部の一部を係合突起が強制通過可能な溝幅に形成したので、ストッパ部材のシリンダからの離脱防止がより確実になる。

[Problems to be solved by the invention]
In the former known example, since the liquid is ejected from the front end of the injection cylinder even if the trigger is inadvertently pulled, it is desirable to provide a safety device for preventing such inadvertent liquid ejection. The latter known example is provided as such a safety device, but even in the latter known example, if the trigger is forcibly pulled with the safety device applied, the trigger and the plunger are slightly moved backward and forward. As a result, the liquid in the container is sucked, and as a result, the liquid excessively flows into the liquid inflow portion from the suction valve to the liquid passage opening / closing mechanism formed by the front portion of the injection cylinder and the nozzle cap. When the nozzle cap is turned to open the opening / closing mechanism, the excessively filled liquid may be ejected from the liquid ejection hole.
The present invention is provided to prevent the inadvertent liquid ejection as described above by providing a safety device that disables the trigger operation.

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a trigger type liquid ejection container according to the present invention will be described with reference to the drawings.
First, a known trigger type liquid ejection container will be briefly described. A main cylinder 1a is erected from the inside of a mounting cylinder 1 fitted to a container body neck and neck portion (not shown), and the cylinder 2 is moved from the front surface of the main cylinder. The front end of the plunger 5 fitted into the cylinder 2 is connected to the upper rear side of the trigger 4 which protrudes forward from the upper end of the cylinder 1a and is pivotally attached to the front of the injection cylinder 3. The liquid in the container is sucked into the cylinder 2 by swinging the trigger 4 in the front-rear direction, and the liquid in the cylinder can be ejected from the front end of the injection cylinder 3.
The trigger 4 is biased forward by a plunger 5 biasing spring provided in the cylinder 2 via a plunger, or by a spring having one end attached to a member other than the trigger 4 such as the main cylinder 1a.
[0010]
In the invention according to claim 1 shown in FIGS. 1 to 4, the trigger 4 has a U-shaped cross section that protrudes rearward from the left and right sides of the front wall 6, and the ridge extends in the vertical direction on the upper outer surfaces of the left and right side walls . A plurality of engaging projections 8 are formed at predetermined intervals in the front-rear direction. An upward stepped portion 9 is formed on the front surface of the front wall 6 at a height substantially equal to the lower end of the engaging protrusion 8.
[0011]
Further, a stopper plate 11 is projected rearward from a rear portion of the rectangular frame 10 fitted to the outer surface of the trigger 4 so as to be movable up and down, thereby forming a stopper member 12. The rear end surface of the stopper plate 11 can be engaged with the front end surface of the cylinder lower portion, and the lower end of the frame 10 is engaged with the upper end of the engaging protrusion 8 at this engaging position of the stopper plate 11.
[0012]
According to the third aspect of the present invention, the nozzle cap 13 having the liquid ejection hole is fitted to the front end portion of the injection cylinder 3 so as to be rotatable, and the nozzle cap 13 is rotated with respect to the injection cylinder 3 in these fitting portions. It is also possible to provide a liquid passage opening / closing mechanism that allows the injection cylinder hole and the liquid ejection hole of the injection cylinder 3 to communicate with each other and to be blocked. This liquid passage opening / closing mechanism is known, for example, as described in Japanese Utility Model Laid-Open No. 62-187665.
In the figure, 14 is a suction pipe communicating with the main cylinder 1a, and the lower end thereof reaches the bottom of a container body (not shown).
[0013]
Next, the operation of this embodiment will be described. When the stopper member 12 is positioned at the upper limit position with respect to the trigger 4, as shown in FIGS. 1 and 2, the rear end surface of the stopper plate 11 is engaged with the lower front end surface of the cylinder 2. Cannot be pulled backwards. In this state, the lower end of the frame body 10 is engaged with the upper end of the engaging protrusion 8, so that the rear end of the stopper plate 11 is prevented from detaching downward from the front end of the cylinder 2.
[0014]
In order to enable the trigger 4 to be pulled rearward, the upper end of the engagement protrusion 8 is overcome, the frame body 10 is lowered, and the stopper plate 11 is released from the cylinder 2 downward. In this state, the front lower end of the frame body 10 is engaged with the upward stepped portion 9, and both the left and right inner surfaces of the frame body 10 are on the engaging protrusion 8.
[0015]
Although it is possible to block the injection cylinder hole of the injection cylinder 3 and the liquid ejection hole of the nozzle cap 13 by a liquid passage opening / closing mechanism (not shown), the trigger 4 is slightly swung back and forth even in this case. However, if the trigger 4 is swung in the shut-off state by the liquid passage opening / closing mechanism, overfilling occurs. When the shut-off is released by connecting the liquid ejection hole and the injection cylinder hole, the liquid is ejected. However, if the trigger 4 cannot be pulled by the stopper member 12, such a situation can be prevented.
[0016]
5 and 6 show a trigger type liquid ejection container according to a second aspect of the present invention. The trigger 20 is formed in a U-shaped cross section that protrudes backward from the left and right sides of the front wall 21 through the side wall 22. Further, a top plate 24 that closes the upper surface between the pair of left and right sliding plates 23 fitted between the left and right side walls 22 of the trigger so as to freely move up and down extends to the rear of the side walls 22 and the extended top plate 24. The short plate 25 is suspended from both the left and right sides of the portion, the top plate 24 and the short plate 25 form a stopper plate 26, and a front plate 27 that closes the front surface between the sliding plates 23 is connected to the trigger front wall 21.
