【0001】
【発明の属する技術分野】
本発明は、トリガー式液体噴出容器に関する。
【0002】
【従来の技術】
容器体口頸部から起立する主筒の前面からシリンダを、主筒上端から射出筒を、それぞれ前方突出すると共に、射出筒前部から垂設したトリガー上部に、上記シリンダ内へ嵌合されて前方突出するプランジャ前端部を係合させて、そのトリガーの前後方向揺動で容器体内液体を吸上げ、継手管を介して射出筒前端へ接続させたノズルキャップから噴出可能に設け、又継手管に対してノズルキャップを回動可能に設けて、第1の特定位置では液体吐出路が開き、第2の特定位置では液体吐出路が閉塞可能に設けたトリガー式液体噴出容器が知られている。
【0003】
【発明が解決しようとする課題】
上記従来例では、継手管前半とノズルキャップとの間に液体吐出路開閉機構が設けられているが、その液体吐出路閉塞状態においてもトリガーを強く引いたり、離したりすると、該トリガーは通常合成樹脂製で或る程度弾性変形するから、プランジャもシリンダ内で多少前進、後退することとなり、そのため上記トリガー操作の度に射出筒内が高圧化して液体吐出路が開放される第1の特定位置までノズルキャップを回したとき、高圧化された射出筒内液体が不用意に噴出して周辺を汚すことがあった。
【0004】
本発明は、ノズルキャップの正逆両方向への回動により上下動してトリガーの操作を可能としたり、又不能とするストッパ部材を設けて、ノズルキャップを液体吐出路が閉塞される第2の特定位置まで回すと、上記ストッパ部材が下降することで、自動的にトリガーの引寄せ操作が不能となるよう設けたものである。
【0005】
【課題を解決するための手段】
容器体口頸部から起立する主筒の前面からシリンダを、主筒上端から射出筒を、それぞれ前方突出すると共に、射出筒前部から垂設したトリガー上部に、上記シリンダ内へ嵌合されて前方突出するプランジャ前端部を係合させて、そのトリガーの前後方向揺動で容器体内液体を吸上げ、継手管を介して、射出筒前端へ接続させたノズルキャップから噴出可能に設け、又継手管に対して、ノズルキャップを回動可能に設けて、第1の特定位置では液体吐出路が開き、第2の特定位置では液体吐出路が閉塞可能に設けたトリガー式液体噴出容器において、
起立板22下端から垂下板23を介して係合板24を後方突出すると共に、該係合板の前後方向中間部下面に前向き段部25を有して係合板の後半下面よりも前半下面を高くし、又上記起立板には嵌合孔26と該孔側方の上下方向にガイド長孔27とを、それぞれ穿設したストッパ部材21を設け、
嵌合孔26を継手管の前部外面へ遊嵌させて継手管7が前後方向中間部に有する仕切り板8とノズルキャップ12との間に起立板22を位置させると共に、係合板24は、プランジャ係合位置よりも下方のトリガーの前壁部分に穿設した透孔31に通し後方突設し、又ノズルキャップ後端面から後方突設した係合棒34を嵌合孔26の内面へ係合させると共に、ガイド長孔27内へ仕切り板8から突出するピン33を摺動可能に嵌合させ、
ノズルキャップ12が第2の特定位置にある状態では、係合板24後端面がシリンダの下部前端面へ係合すると共に、係合板24の前向き段部25前面へ、トリガー前壁に穿設した透孔31下縁から後方突出する横設板32の後端面を係合させて設け、上記第2の特定位置から継手管7を中心として第1の特定位置へノズルキャップ12を回動させると、係合棒34が嵌合孔26内壁面に沿って上方へ摺動し乍ら嵌合孔内壁面を押上げることでストッパ部材21を押上げ可能となし、ノズルキャップ回動により係合棒34が起立板上方部分へ移動したとき、係合板後端面は、シリンダの下部前端面とプランジャ下面との間へ、又前向き段部25は横設板32の後端面上方へ、それぞれ移動可能に形成した。
【0006】
【発明の実施の形態】
以下図面について説明する。まず従来公知の部分について説明すると、1は容器体、2はその容器体口頸部外面へ螺合させた装着筒で、該装着筒を下端に有して、図示しない主筒が起立し、該主筒前面からシリンダ3を、又上端から射出筒4を、それぞれ前方突出する。その射出筒前部からはトリガー5が垂下され、該トリガーの上部後面へは上記シリンダ3内へ嵌合されて前方突出するプランジャ6前端部を係合させている。トリガーはプランジャ又はその他部分で前方付勢させておく。
【0007】
上記射出筒前端からは継手管7を介してノズルキャップを前方突出させる。継手管7は前後方向中間に仕切り板8を有し、該仕切り板後方の継手管部分を射出筒4前部へ嵌着させ、又仕切り板前方の継手管部分外面へノズルキャップ12を回動可能に嵌合させている。
【0008】
上記仕切り板の中央部からは流路形成棒9を、又該棒を囲んでノズルキャップ嵌合筒10を、それぞれ前方突出し、それ等棒とノズルキャップ嵌合筒との間の仕切り板部分に透孔11を穿設している。
【0009】
ノズルキャップ12は周壁13の前後方向中間部に仕切壁14を有し、該仕切壁中心にノズル孔15を穿設すると共に、そのノズル孔を囲んで後方へ流路形成筒16を突出し、上記流路形成棒9外面と流路形成筒16内面とに、それぞれ穿設した溝で液体吐出路一部を形成し、ノズルキャップ回動で上記両溝が連通する位置をノズルキャップの第1の特定位置とし、又上記両溝が位置ずれして液体吐出路が遮断されるノズルキャップの位置を第2の特定位置としている。尚17はカバーである。
【0010】
本発明にあっては、図5が示すように、起立板22下端から垂下板部23を介して係合板24を後方突出すると共に、該係合板の前後方向中間部下面に前向き段部25を有して係合板の後半下面よりも前半下面を高くし、又上記起立板には嵌合孔26と該孔側方に上下方向へのガイド長孔27とを、それぞれ穿設したストッパ部材21を設け、上記嵌合孔26を継手管7前部へ遊嵌させて仕切り板8とノズルキャップ12との間に位置させ、又係合板24はトリガー前壁に穿設した透孔31に通して、後方突出させ、図1が示す、ノズルキャップの第2特定位置にあっては、その係合板後端面をシリンダ3の下部前端面へ係合させると共に、上記トリガー前壁の透孔31下縁から後方突設した横設板32の後端面を、既述係合板の前向き段部25前面へ係合させている。又図5と図6とが示すようにガイド長孔27内へは仕切り板8前面から突設したピン33を摺動可能に嵌合させている。尚上記トリガー前壁に穿設する透孔31は上下方向に長く設けて垂下板24の下部も挿入可能とすることが出来る。
【0011】
既述起立板22に穿設する嵌合孔26は、上下方向に長い楕円の左右一方の側面に、張出切欠き部26a を設け、該切欠き部を嵌合孔の一部としている。該張出し切欠き部の側縁は嵌合孔の頂部内面から下側方へ半放物線状に延び、かつその下側方の半放物線状部分先端からその先端上内方の嵌合孔部分へ傾斜面状に延びている。その傾斜面状部は後述係合棒の係合段部26b を形成する。
【0012】
上記嵌合孔26内へは、ノズルキャップ12の外周部後端面から後方突出させた係合棒34を図6が示すように挿入させる。該係合棒は液体吐出路開閉のためのノズルキャップ12の回動で、嵌合孔26に対して図2が示すように下側方へ移動したり、又図3が示すように上方へ移動したりする。係合棒34が下側方に位置するとき、ノズルキャップ12は第2特定位置にあって液体吐出路を閉塞し、又ノズルキャップを回して係合棒34を上方へ移動させたとき、ノズルキャップは第1特定位置へ移動し、このとき液体吐出路は開放している。
【0013】
上記ノズルキャップ回動による係合棒34の移動の際、該係合棒は嵌合孔26の内壁面に接し摺動することで、継手管7に対する嵌合孔26の位置を上方へ押上げたり、又下降させたりする。即ち、係合棒34が図2が示すように下側方に位置するとき、図1が示すように嵌合孔26の上部内面は継手管7の上面に接し、又嵌合孔の下部内面と継手管下面との間には間隙が形成されており、該状態からノズルキャップ12を回すと、係合棒34も嵌合孔26の側面、正確には既述張出し切欠き部26a の内面に沿って上方へ移動するが、図1が示すように嵌合孔26の上部内面が継手管7上面に接する状態では、継手管7の中心軸線から嵌合孔26の上部内面までの距離よりも、継手管中心軸線から係合棒34の外面までの距離が大であるため、係合棒が上方へ近ずくにつれて係合棒は嵌合孔26の内面に沿って摺動し乍ら嵌合孔内壁面を上方へ押上げ、図3のように係合棒34が上方へ達したとき、嵌合孔の上部内壁面は係合棒34の上面に接している。
【0014】
係合棒34が嵌合孔26の内壁面を介してストッパ部材21を引上げることで、ストッパ部材21の係合板24は、図1が示す既述の位置から図3が示す位置まで引上げられ、又ノズルキャップ12を上記と逆方向へ回すことで図3の位置から図1の位置へ復帰する。図3が示す位置において、係合板24後端面はシリンダ3の下部前端面とプランジャ6との間へ移動し、又前向き段部25は横設板32の後端面から外れ、上方へ移動する。よって該状態ではトリガー5の操作が可能となり、ノズルキャップは第1の特定位置にあって液体吐出路を開放しているため、液体噴出操作が可能である。
【0015】
【発明の効果】
本発明は既述構成とするものであり、液体吐出路が閉塞する、図1のノズルキャップ第1特定位置では、ストッパ部材21の係合板24後端面がシリンダ3の下部前端面へ係合すると共に、該係合板が下面に有する前向き段部25へ、トリガー前壁に穿設した透孔31下縁から後方突出する横設板32の後端面が係合するから、又上記透孔31はプランジャ6係合位置よりも下方に穿設するから、該液体吐出路閉塞状態ではトリガー操作しても、又該トリガーが多少弾性変形しても、上記前向き段部25に後端面を係合する横設板32より上方のトリガー部分は弾性変形することがなく、よって従来のようにプランジャ6が動くことは全くなく、よって既述従来例の欠点を除くことが出来る。
【0016】
又上記係合板24を有するストッパ部材21は、ノズルキャップ12を第1の特定位置から第2の特定位置へ、又該第2の特定位置から第1の特定位置へ回動させるだけで上下動して既述トリガー操作を不能とする係止板位置とトリガー操作を可能とする上昇位置との間を上下動するよう設けたから、そのトリガー操作を不能とする安全装置を施す操作と該安全装置を外す操作が極めて容易であり、簡単に行うことが出来る。又上記ストッパ部材21は継手管7の仕切板8とノズルキャップ12との間およびその下方にあって、上記操作によって上下動するだけであるから、ノズルキャップおよびトリガー側方へ突出する安全装置に比べて他物の邪魔となることもない。

A specific position is set, and the position of the nozzle cap at which the two grooves are displaced and the liquid discharge path is blocked is defined as a second specific position. Reference numeral 17 denotes a cover.
[0010]
In the present invention, as shown in FIG. 5, the engagement plate 24 protrudes rearward from the lower end of the upright plate 22 through the hanging plate portion 23, and a forward stepped portion 25 is provided on the lower surface of the intermediate portion in the front-rear direction of the engagement plate. A stopper member 21 having a front half lower surface than a rear lower surface of the engagement plate, and a fitting hole 26 in the upright plate and a guide long hole 27 in the vertical direction on the side of the hole. The fitting hole 26 is loosely fitted to the front part of the joint pipe 7 so as to be positioned between the partition plate 8 and the nozzle cap 12, and the engagement plate 24 is passed through a through hole 31 formed in the front wall of the trigger. 1, the rear end face of the nozzle cap is engaged with the lower front end face of the cylinder 3, and the trigger cap wall is below the through hole 31 in the second specific position shown in FIG. The rear end surface of the horizontal plate 32 projecting rearward from the edge is engaged with the front surface of the forward stepped portion 25 of the aforementioned engagement plate. Further, as shown in FIGS. 5 and 6, a pin 33 protruding from the front surface of the partition plate 8 is slidably fitted into the guide slot 27. The through hole 31 formed in the front wall of the trigger is provided long in the vertical direction so that the lower part of the hanging plate 24 can be inserted.
[0011]
The fitting hole 26 drilled in the upright plate 22 is provided with an overhang notch 26a on one of the left and right sides of an ellipse that is long in the vertical direction, and the notch is a part of the fitting hole. The side edge of the overhang notch extends in a semi-parabolic shape from the top inner surface of the fitting hole to the lower side, and is inclined from the tip of the lower semi-parabolic part to the fitting hole portion on the inner side of the tip. It extends in a planar shape. The inclined surface portion forms an engagement step portion 26b of an engagement rod which will be described later.
[0012]
As shown in FIG. 6, the engaging rod 34 protruded rearward from the rear end surface of the outer peripheral portion of the nozzle cap 12 is inserted into the fitting hole 26. The engagement rod is moved downward as shown in FIG. 2 with respect to the fitting hole 26 by the rotation of the nozzle cap 12 for opening and closing the liquid discharge path, or upward as shown in FIG. Or move. When the engaging rod 34 is positioned on the lower side, the nozzle cap 12 is in the second specific position and closes the liquid discharge path, and when the engaging cap 34 is moved upward by turning the nozzle cap, the nozzle The cap moves to the first specific position, and the liquid discharge path is open at this time.
[0013]
When the engagement rod 34 is moved by rotating the nozzle cap, the engagement rod slides in contact with the inner wall surface of the fitting hole 26 to push the position of the fitting hole 26 with respect to the joint pipe 7 upward. Or descend. That is, when the engaging rod 34 is positioned on the lower side as shown in FIG. 2, the upper inner surface of the fitting hole 26 is in contact with the upper surface of the joint pipe 7 as shown in FIG. When the nozzle cap 12 is turned from this state, the engagement rod 34 is also attached to the side surface of the fitting hole 26, more precisely, the inner surface of the overhang notch 26a described above. 1, when the upper inner surface of the fitting hole 26 is in contact with the upper surface of the joint pipe 7 as shown in FIG. 1, the distance from the center axis of the joint pipe 7 to the upper inner surface of the fitting hole 26 However, since the distance from the joint pipe central axis to the outer surface of the engagement rod 34 is large, the engagement rod slides along the inner surface of the fitting hole 26 and fits as the engagement rod approaches upward. When the inner wall surface of the fitting hole is pushed upward and the engaging rod 34 reaches the upper side as shown in FIG. 3, the upper inner wall surface of the fitting hole is in contact with the upper surface of the engaging rod 34.

When the engaging rod 34 pulls up the stopper member 21 through the inner wall surface of the fitting hole 26, the engaging plate 24 of the stopper member 21 is pulled up from the position shown in FIG. 1 to the position shown in FIG. Further, the nozzle cap 12 is returned to the position shown in FIG. 1 from the position shown in FIG. In the position shown in FIG. 3, the rear end surface of the engagement plate 24 moves between the lower front end surface of the cylinder 3 and the plunger 6, and the forward stepped portion 25 moves away from the rear end surface of the lateral plate 32 and moves upward. Therefore, in this state, the trigger 5 can be operated, and since the nozzle cap is in the first specific position and the liquid discharge path is opened, the liquid ejection operation is possible.
[0015]
【The invention's effect】
The present invention is configured as described above, and the engagement plate 24 rear end surface of the stopper member 21 is engaged with the lower front end surface of the cylinder 3 at the nozzle cap first specific position of FIG. At the same time, since the rear end surface of the lateral plate 32 projecting rearward from the lower edge of the through hole 31 drilled in the front wall of the trigger is engaged with the forward stepped portion 25 of the engaging plate on the lower surface, the through hole 31 Since the plunger 6 is drilled below the position where the plunger 6 is engaged, the rear end face is engaged with the forward stepped portion 25 even if the trigger is operated or the trigger is somewhat elastically deformed when the liquid discharge path is closed. The trigger portion above the horizontal plate 32 is not elastically deformed. Therefore, the plunger 6 does not move at all as in the prior art, so that the disadvantages of the conventional example described above can be eliminated.
[0016]
The stopper member 21 having the engagement plate 24 moves up and down simply by rotating the nozzle cap 12 from the first specific position to the second specific position and from the second specific position to the first specific position. Since the above-described locking plate position that disables the trigger operation and the raised position that enables the trigger operation are provided to move up and down, an operation for applying a safety device that disables the trigger operation and the safety device The operation of removing is extremely easy and can be performed easily. The stopper member 21 is located between and below the partition plate 8 of the joint pipe 7 and the nozzle cap 12 and only moves up and down by the above operation. Therefore, the stopper member 21 is a safety device that protrudes to the side of the nozzle cap and trigger. Compared to other things, it does not get in the way.
