【０００４】
【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内から主筒を起立し、該主筒前面からシリンダ１を、かつ主筒上端から射出筒２を、それぞれ前方突出し、又射出筒前部に枢着させて垂設したトリガー３の上方後部に、上記シリンダ１内へ嵌合させたプランジャ４前端部を連結し、かつトリガー３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１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３の左右両側壁６外面へ左右両側板１２を嵌合させたコ字形状の回動部材１１の横板１３後面から係合突部１６を突設すると共に、横板１３前面から左右方向への回動軸１５を前方突設して、該回動軸の左右両端部を上記左右両軸穴８へ回動自在に嵌合させて、トリガー３に対して回動部材１１を上下方向へ回動自在に形成し、
上記係合突部１６を、上記プランジャ４より下方シリンダ１部分前端内面へ係合させた状態では、横板１３後面とシリンダ１の下部前端面とが係合してトリガー３の後方引寄せが不能で、又シリンダ１から下方へ離脱させた状態ではトリガー３の後方引寄せが可能に形成した。
【０００６】
第２の手段として、上記第１の手段を有すると共に、射出筒２前端部へ回動可能に液体噴出部を有するノズルキャップ１７を嵌合させ、これらの嵌合部に、射出筒２に対するノズルキャップ１７の回動で射出筒２が有する射出筒孔と液体噴出部とを連通させ、又遮断させることが自在な液体通路開閉機構を設けた。
【０００７】
第３の手段として、容器体口頸部へ嵌合させた装着筒内から主筒を起立し、該主筒前面からシリンダ１を、かつ主筒上端から射出筒２を、それぞれ前方突出し、又射出筒前部に枢着させて垂設したトリガー３の上方後部に、上記シリンダ１内へ嵌合させたプランジャ４前端部を連結し、かつトリガー３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１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３を前壁５の左右から側壁６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６の外面へ突出板部７を付設し、これら両突出板部に形成した左右方向への軸穴８後部を、該軸穴内径よりも小さい寸法で開口して、該開口部の上下両縁に連続させて後方拡開のテーパ溝１０を設けておき、
上記トリガー３の左右両側壁６外面へ左右両側板１２を嵌合させたコ字形状の回動部材１１の横板１３後面から係合突部１６を突設すると共に、左右両側板１２の前後方向中間部内面から左右方向へ回動軸１５ａを突設して、これら回動軸の先端部を上記左右両軸穴８ａへ回動自在に嵌合させて、トリガー３に対して回動部材１１を上下方向へ回動自在に形成し、

【０００８】
【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内から主筒を起立し、該主筒前面からシリンダ１を、かつ主筒上端から射出筒２を、それぞれ前方突出し、また射出筒２前部に枢着させて垂設したトリガー３の上部後側に、シリンダ１内へ嵌合させたプランジャ４前端部を連結し、トリガー３の前後方向揺動で容器体内液体をシリンダ１内へ吸込み、かつ該シリンダ内液体を射出筒２前端から噴出可能に設けている。
なお、トリガー３は、シリンダ１内に設けたプランジャ４付勢用のバネによりプランジャを介して、又は主筒等のトリガー３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。
【０００９】
本発明では、トリガー３を、前壁５の左右から側壁６を後方突出する横断面コ字形状として、プランジャ４前端部より下方の左右両側壁６部分内面へ突出板部７を付設し、これら両突出板部に軸線が左右方向の軸穴８を形成すると共に、該軸穴後部を、その軸穴内径よりも小さい寸法で開口して、該開口部９の上下両縁に連続させて後方へ拡開するテーパ溝１０を形成する。
【００１０】
トリガー３の左右両側壁６外面へコ字形状の回動部材１１の左右両側板１２を嵌合させると共に、両側板１２後端の上部間に位置する横板１３の左右方向中間部前面から、側板１２の前後方向中間部に至る長さの連結板１４を突設し、該連結板前端から左右に長い断面円形状の回動軸１５を突設して、該回動軸の左右両端部を左右両軸穴８へ回動自在に嵌合させる。
【００１１】
また横板１３後面上部の左右両部に、上下方向に細長で、かつ上下両端部の角部を切除して傾斜面に形成した係合突部１６を形成する。
さらに横板１３と両側板１２とのそれぞれの下部前面の角部を切除して傾斜面に形成する。
なお、１２ a は左右両側板１２のそれぞれの左右方向外面に形成した前後に長い指掛け突条である。
【００１２】
上記ではトリガー３の左右両側壁６内面に軸穴８を有する突出板部７を形成したが、これに限らず請求項３に記載し、かつ図５に示すように、突出板部７を両側壁６外面に付設することも可能である。この場合には横板１３から回動軸１５付きの連結板１４を突設することなく、左右両側壁６の前後方向中間部内面から左右方向へ回動軸を１５ａを突設して、これら回動軸先端部を軸穴８ａへ回動自在に嵌合させる。
【００１３】
なお、請求項２記載のように、射出筒２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１７を嵌合させ、これら射出筒２とノズルキャップ１７との嵌合部に、射出筒２に対するノズルキャップ１７の回動で射出筒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。
【００１４】
次に本実施形態の作用について説明する。
図１はトリガー３の後方引寄せが可能な状態を示し、この状態では回動部材１１はシリンダ１から離間して、横板１３の傾斜面がトリガー３の左右両側壁６後面へ当接している。一方、左右両側板１２の下部前面の角部は切除されて傾斜面を形成しているため、角部がトリガー３の前面へ突出することがなく、従って、トリガー３の後方への引寄せ時に角部が手に接触することがない。
【００１５】
トリガー３の後方への引寄せを不能にするためには回動部材１１を反時計方向へ回動させればよく、すると係合突部１６上端がシリンダ１前端下面へ係合した後、さらに上昇してシリンダ前端を越え、この時点で手を離すと、図２及び図３に示すように係合突部１６下端がシリンダ１前端内面へ係合する。この状態でトリガー３を後方へ引寄せようとしても、横板１３後面がシリンダ１前端面へ係合しているため引寄せ不能である。
【００１６】
なお、液体通路開閉機構により液体噴出孔と射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３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３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、上記の手段によりトリガー３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。
【００１７】
【発明の効果】
請求項１乃至３記載のトリガー式液体噴出容器は、トリガーに取り付けた回動部材をシリンダへ係合可能に設けたので、不使用時におけるトリガー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可能になる。
【００１８】
請求項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ことができるため、液体通路開閉機構により液体噴出孔と射出孔とを遮断させても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。

BACKGROUND OF THE INVENTION
The present invention relates to a trigger type liquid ejection container.
[0002]
[Prior art]
For example, as shown in Japanese Utility Model Laid-Open No. 6-31854, the main cylinder is erected from the inside of the mounting cylinder fitted to the container body neck and neck, the cylinder from the front surface of the main cylinder, and the injection cylinder from the upper end of the main cylinder, The front and rear direction of the trigger is such that the front end of the plunger fitted into the cylinder is connected to the upper rear part of the trigger that protrudes forward and is pivotally attached to the front part of the injection cylinder, and the trigger is biased forward. 2. Description of the Related Art A trigger-type liquid ejection container is known in which a liquid in a container is sucked into a cylinder by swinging and the liquid in the cylinder is ejected from the front end of an injection cylinder.
[0003]
Further, as shown in Japanese Utility Model Publication No. 62-187665, a nozzle cap having a liquid ejection hole is fitted to the front end portion of the injection cylinder so as to be rotatable, and the nozzle cap is rotated with respect to the injection cylinder at these fitting portions. It is also known to provide a liquid passage opening / closing mechanism that allows the injection cylinder hole and the liquid ejection hole of the injection cylinder to communicate with each other and to be blocked.
[0004]
[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.

[0008]
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 brief description will be given of a known trigger type liquid ejection container. A main cylinder is erected from the inside of a mounting cylinder fitted to a container body neck which is not shown, and the cylinder 1 is raised from the front surface of the main cylinder and the upper end of the main cylinder. The front end of the plunger 4 fitted into the cylinder 1 is connected to the upper rear side of the trigger 3 projecting forward from each of the injection cylinders 2 and pivotally attached to the front part of the injection cylinder 2. The liquid in the container is sucked into the cylinder 1 by swinging in the front-rear direction, and the liquid in the cylinder can be ejected from the front end of the injection cylinder 2.
The trigger 3 is biased forward by a plunger 4 biasing spring provided in the cylinder 1 via a plunger or a spring having one end attached to a member other than the trigger 3 such as a main cylinder.
[0009]
In the present invention, the trigger 3 is formed in a U-shaped cross section that protrudes backward from the left and right sides of the front wall 5, and the protruding plate portions 7 are attached to the inner surfaces of the left and right side walls 6 below the front end of the plunger 4. Both projecting plate portions are formed with shaft holes 8 whose left and right axes are formed in the left and right directions, and the rear portions of the shaft holes are opened with dimensions smaller than the inner diameters of the shaft holes, and are continuously connected to the upper and lower edges of the opening 9 A tapered groove 10 is formed to expand to the right.
[0010]
The left and right side plates 12 of the U-shaped rotating member 11 are fitted to the outer surfaces of the left and right side walls 6 of the trigger 3, and from the front in the left and right direction middle portion of the horizontal plate 13 located between the upper portions of the rear ends of the both side plates 12, A connecting plate 14 having a length that reaches the middle portion in the front-rear direction of the side plate 12 is projected, and a pivot shaft 15 having a circular cross section that is long to the left and right is projected from the front end of the coupling plate. Is fitted to the left and right shaft holes 8 so as to be rotatable.
[0011]
Further, on both left and right portions of the upper rear surface of the horizontal plate 13, there are formed engaging protrusions 16 that are elongated in the vertical direction and are formed on the inclined surfaces by cutting off the corners at both the upper and lower ends.
Further, the corners of the lower front surfaces of the horizontal plate 13 and the side plates 12 are cut out to form inclined surfaces.
Incidentally, the 12 a is a long finger-hooking protrusion around which is formed on each of the right and left direction outer surface of the left and right side plates 12.
[0012]
In the above description, the protruding plate portion 7 having the shaft hole 8 is formed on the inner surfaces of the left and right side walls 6 of the trigger 3. However, the present invention is not limited to this, and as shown in FIG. It is also possible to attach to the outer surface of the wall 6. In this case, without providing the connecting plate 14 with the rotating shaft 15 from the horizontal plate 13, the rotating shaft 15a protrudes from the inner surface in the front-rear direction middle portion of the left and right side walls 6 in the left-right direction. The tip end of the rotating shaft is fitted into the shaft hole 8a so as to be freely rotatable.
[0013]
In addition, as described in claim 2, a nozzle cap 17 having a liquid ejection hole is rotatably fitted to the front end portion of the injection cylinder 2, and the injection cylinder is fitted to a fitting portion between the injection cylinder 2 and the nozzle cap 17. 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 to communicate with each other and to be blocked by the rotation of the nozzle cap 17 with respect to 2. This liquid passage opening / closing mechanism is known, for example, as described in Japanese Utility Model Laid-Open No. 62-187665.
[0014]
Next, the operation of this embodiment will be described.
FIG. 1 shows a state in which the trigger 3 can be pulled backward. In this state, the rotating member 11 is separated from the cylinder 1, and the inclined surface of the horizontal plate 13 is in contact with the rear surfaces of the left and right side walls 6 of the trigger 3. Yes. On the other hand, the corners of the lower front surfaces of the left and right side plates 12 are cut off to form an inclined surface, so that the corners do not protrude to the front surface of the trigger 3, and therefore when the trigger 3 is pulled backward. The corner does not touch the hand.
[0015]
In order to disable the trigger 3 from being pulled backward, the rotating member 11 may be rotated counterclockwise. After the upper end of the engaging projection 16 is engaged with the lower surface of the front end of the cylinder 1, When it rises and exceeds the front end of the cylinder and is released at this point, the lower end of the engaging protrusion 16 is engaged with the inner surface of the front end of the cylinder 1 as shown in FIGS. Even if the trigger 3 is to be pulled backward in this state, it cannot be pulled because the rear surface of the horizontal plate 13 is engaged with the front end surface of the cylinder 1.
[0016]
It is possible to block the liquid ejection hole and the injection hole by the liquid passage opening / closing mechanism, but even in this case, it is not impossible to slightly swing the trigger 3 back and forth. When the trigger 3 is swung in the shut-off state by the opening / closing mechanism, overfilling occurs, and when the shut-off is canceled by connecting the liquid ejection hole and the injection hole, the liquid is ejected. Such a situation can be prevented beforehand by making 3 impossible to draw.
[0017]
【The invention's effect】
Since the trigger type liquid ejection container according to claims 1 to 3 is provided with a rotating member attached to the trigger so as to be engageable with the cylinder, the trigger pulling when not in use can be made impossible. This makes it possible to prevent eruptions other than the original purpose.
[0018]
In the trigger type liquid ejection container according to claim 2, since the trigger can be prevented from being pulled backward, even if the liquid ejection hole and the injection hole are blocked by the liquid passage opening / closing mechanism, the trigger is caused by overfilling. Unexpected eruptions can be prevented in advance.
