【発明の属する技術分野】
本発明は、トリガー式の液体噴出器に関する。
【0002】
【従来の技術】
特開2001-10655号が示すように、射出筒前端部が形成する嵌合筒外面へ、ノズルキャップを回動自在に嵌合させると共に、射出筒前部とノズルキャップとの間に介在させて嵌合筒外面へ上下動自在に嵌合させたストッパ部材を、ノズルキャップの正方向回動で上昇し、かつ逆方向回動で下降可能に形成し、又射出筒前部から後方向への揺動が可能に、かつ前方付勢させて垂下させたトリガーに対して、上記ストッパ部材下部を、下降位置にあっては係合し、かつ上昇位置にあっては離脱して、該離脱位置でだけトリガー後方引き寄せ操作が可能としたトリガー式液体噴出器が知られている。
【0003】
【発明が解決しようとする課題】
上記トリガー式液体噴出器は、トリガー後面から後方突出させたプランジャ押込み用係合板よりも、ストッパ部材と係合させてトリガーの後方揺動を阻止させる係合板を、トリガー後面の下方部分から突出させることとなるため、又そのストッパ部材は射出筒前部へ遊嵌させて垂下するためストッパ部材が大形化して余分の資材を必要とすることとなり、従って又ストッパ部材を上下動させるためのノズルキャップ回動にも多くの力を要することとなるものであった。
【0004】
更にストッパ部材の下部には、該ストッパ部材下降時におけるトリガー引寄せ操作により、トリガーの係合部が圧接することとなるから相当の強度が要求されるが、該ストッパ部材はノズルキャップの正逆回動により上下動させるため摺動させ易いことが望ましく、強度を高めるための大形化は好ましくない。
【0005】
本発明は上記各問題を除去すると共に、その他諸問題を解決可能に設けたものである。
【0006】
【課題を解決するための手段】
第1の手段として、射出筒3前端部が形成する嵌合筒4外面へ、ノズルキャップ5を回動自在に嵌合させると共に、射出筒3前部に設けた前向き段部とノズルキャップ5との間へ介在させて嵌合筒4外面へ上下動自在に嵌合させたストッパ部材10を、ノズルキャップ5の正方向回動により上昇し、かつ逆方向への回動により下降可能に形成し、又射出筒前部から後方向への揺動が可能に、かつ前方付勢させて垂下させたトリガー7に対して、上記ストッパ部材10下部を、下降位置にあっては係合し、かつ上昇位置にあっては離脱して、該離脱位置でだけトリガー後方引寄せ操作が可能とした、トリガー式液体噴出容器において、
上記ストッパ部材10を、嵌合筒4外面へ遊嵌させた摺動縦板11の下端部から第1係合板12を後方突出すると共に該第1係合板の後部下面から係合突部12a を、該係合突部の後面は、該トリガー式液体噴出器が有するシリンダ6前端面へ係合不能に垂下させて形成し、
又射出筒3下面とシリンダ6上面とを補強板3aで連結させ、該補強板前面を摺動縦板11と平行に位置させて、上記係合突部12a が補強板3a前面に接して上下動自在に設け、
ストッパ部材10下降時には、トリガー上部から後方突出する第2係合板14後面が係合突部12a 前面へ接し、又ストッパ部材上昇時には第2係合板14と係合突部12a とが係合不能に形成した。
【0007】
第2の手段として、上記第1の手段を有数と共に上記補強板3a前面を、シリンダ6前端面よりも前方に位置させた。
【0008】
第3の手段として、上記第1又は第2の手段を有すると共に、上記補強板3aを左右一対として、射出筒3下面とシリンダ6上面との各左右両側部間に小間隙を介して平行に並設させると共に、上記第1係合板12後端面の左右方向中間部から案内子12b を後方突設して、該案内子を上記小間隙内へ上下動自在に嵌合させた。
【0009】
第4の手段として、上記第1、第2又は第3の手段を有すると共に、上記射出筒前端部の下面を除く外面から外方へ張出し板15を突出して、これ等張出し板の左右両外端部から前方へ、内面に縦溝16、16を有するガイド板17、17を突出して、それ等両縦溝内へ、上記摺動縦板11の左右両側部を上下動自在に嵌合させた。
【0010】
【発明の実施の形態】
以下図面について説明する。まず従来公知の構造について簡単に説明すると、1は容器体、2は該容器体の口頸部へ嵌合させた装着筒で、該装着筒内からは主筒を起立し、該主筒上端から射出筒3を前方突出している。該射出筒前端部は嵌合筒4とし、該嵌合筒外面へノズルキャップ5を回動自在に嵌合させている。又主筒面の射出筒後部の下面からはシリンダ6を下前方へ傾斜させて突設している。更に射出筒3の前部からは後方向への揺動が可能にトリガー7を垂下し、該トリガー後面から上記シリンダ内へ前方付勢して嵌合されたプランジャ8用押込み板9を突出する。
【0011】
更に摺動縦板11下端から第1係合板12を後方突出するストッパ部材10の上記摺動縦板11を、図3のように該手動縦板に穿設した嵌合孔13を嵌合筒4の基部外面へ上下動自在に遊嵌させて垂下している。又ノズルキャップ5の後端面一部からは、図3が示す係合子5aを突設して上記嵌合孔13内へ遊挿させており、ノズルキャップ5を回動させることで係合子5aが嵌合筒4外面に沿って移動し、図4のように嵌合筒上面の上方へ位置したとき、摺動縦板11が押し上げられ、又図3のように係合子5aが嵌合筒4の側外方へ移動することで摺動縦板11が下降するよう設けている。
【0012】
本発明にあっては、図4が示すように摺動縦板11が押し上げられたとき、摺動縦板下端から後方突出する第1係合板12が射出筒3の前部下面へ当接ないし近接するよう設けて摺動縦板11の高さを短かく設けた。第1係合板12は後部下面から係合突部12a を垂下しており、図4が示すようにストッパ部材10上昇時にあっては、トリガー7は後方揺動が可能となる。即ち、図1が示すようにストッパ部材下降時にあっては、トリガー7後面から突設した第2係合板14が係合突部12a 前面に接しているため、トリガーの後方揺動は不能であるが、図4のようにストッパ部材10上昇により上記係合突部12a が上方へ移動することで、トリガー7を揺動させても第2係合板14と係合突部12a とは係合せず、よって第2係合板14よりも下方に設けられたプランジャ押込み板9は、プランジャ8をシリンダ奥部内へ付勢に抗して押込み、シリンダ加圧により射出筒を通ってノズルキャップから液体を噴出する。
【0013】
又図3が示すように射出筒3下面とシリンダ6上面とを連結する補強板3aを設け、上記係合突部12a 後面を補強板前面に接して上下動可能に設けた。該補強板前面はストッパ部材10の摺動縦板11と平行させる。
【0014】
又補強板前面はシリンダ6の前端よりも前方に位置させる。
【0015】
図示例にあっては上記補強板を左右一対として射出筒下面とシリンダ上面との左右両側部間に小間隙を介して平行に設け、又図1が示すように第1係合板12後面の左右方向中間部から案内子12b を後方突出させて上記小間隙内へ上下動自在に嵌合させた。
【0016】
更に図示例にあっては、嵌合筒4の下面を除く外面部分からフランジ状に張出し板15を突出させ、かつ該張出し板の左右両外端部から前方へ、内面に縦溝16、16を有するガイド板17、17を突出して、それ等両縦溝内へ、図5のように摺動縦板11の左右両側部を上下動自在に嵌合させている。
【0017】
上記構成において、図1が示すようにストッパ部材10が下降している状態にあっては、トリガー7を後方へ揺動させようとしても、トリガー7上部から後方突出する第2係合板14後端面が、係合突部12a 前面へ接するため、又第1係合板12後面は補強板3a、3a前面に接しているため、後方へ揺動させることは出来ず、よってトリガーから後方突出するプランジャ押込み板9もプランジャ8を押込みすることが不能である。尚このときノズルキャップのノズル孔5bは閉塞されている。
【0018】
次にノズルキャップ5を回動させ、係合子5aを嵌合筒4の上面へ移動させると、摺動縦板11はその左右両側がガイド板17、17の縦溝16、16内へ嵌合されており、かつ係合突部5aの後面は、補強板3a、3aの前面へ上下動自在に接しているため、上方へ押し上げられることとなり、このときストッパ部材10の第1係合板12は射出筒3下面近くまで引き上げられ、よってトリガー7を後方へ揺動させることが出来る。このときノズル孔5bは開孔され、よって射出筒内液体はノズル孔を通って噴出される。
【0019】
【発明の効果】
本発明は既述構成とするもので、請求項1記載のようにノズルキャップ5回動によってストッパ部材10が上昇したとき、該ストッパ部材の第1係合板12が射出筒3下面へ当接ないし近接するよう設けたから、既述従来例に比してストッパ部材の高さを短かく形成でき、従って該ストッパ部材成形材料も少なくすることが出来る。従って又ストッパ部材を上下動させるためのノズルキャップの回動を容易とすることが出来る。
【0020】
又射出筒3下面とシリンダ6上面とを補強板3aで連結したから、射出筒3とシリンダ6と主筒との一体性を高めることが出来、係合突部12a 後面はシリンダ6前端面へ係合不能としたから、トリガー引寄せ時に第1係合板12ないし係合突部12a 後面がシリンダ6の前面へ圧接してシリンダに悪影響を及ぼすこともない。更にその補強板3a、3a前面はストッパ部材の摺動縦板11と平行させて設けたから、ストッパ部材10上下動時の摩擦抵抗を減少させることが出来る。
【0021】
請求項2のように、補強板3a前面を、シリンダ6前端面よりも前方に位置させることで、トリガー引寄せ時に第1係合板12ないし係合突部12a 後面がシリンダ6前面へ圧接することを確実に防止できる。
【0022】
請求項3のようにすることで、案内子12b により補強板3a、3a前面に対する第1係合板12の横ずれを防止できる。
【0023】
請求項4のようにすることで、ノズルキャップ5回動によるストッパ部材10の上下動が容易となる。

[0002]
[Prior art]
As shown in Japanese Patent Application Laid-Open No. 2001-10655, the nozzle cap is rotatably fitted to the outer surface of the fitting cylinder formed by the front end of the injection cylinder, and is interposed between the front of the injection cylinder and the nozzle cap. A stopper member fitted to the outer surface of the fitting cylinder so as to be movable up and down is formed so that it can be raised by rotating the nozzle cap in the forward direction and can be lowered by turning in the reverse direction. The lower part of the stopper member is engaged in the lowered position and detached in the raised position with respect to the trigger that is swingable and biased forward, and is detached in the raised position. There is known a trigger type liquid ejector capable of pulling back the trigger only at the top.
[0003]
[Problems to be solved by the invention]
The trigger-type liquid ejector protrudes from the lower part of the rear surface of the trigger, rather than the engaging plate for pushing the plunger, which protrudes backward from the rear surface of the trigger. Therefore, the stopper member is loosely fitted to the front part of the injection cylinder and hangs down, so that the stopper member becomes large and requires extra materials. Therefore, the nozzle for moving the stopper member up and down is also required. A large amount of force is also required to rotate the cap.
[0004]
Furthermore, the trigger member is pressed against the lower part of the stopper member by the trigger pulling operation when the stopper member is lowered, so that a considerable strength is required. It is desirable to make it easy to slide because it is moved up and down by rotation, and it is not preferable to increase the size to increase the strength.
[0005]
The present invention eliminates the above problems and provides other problems.
[0006]
[Means for Solving the Problems]
As a first means, the nozzle cap 5 is rotatably fitted to the outer surface of the fitting cylinder 4 formed by the front end portion of the injection cylinder 3, and the forward stepped portion provided at the front part of the injection cylinder 3 and the nozzle cap 5 are provided. A stopper member 10 that is interposed between them and fitted to the outer surface of the fitting cylinder 4 so as to be movable up and down is formed so that it can be raised by rotating the nozzle cap 5 in the forward direction and lowered by turning in the reverse direction. Further, the lower portion of the stopper member 10 is engaged with the trigger 7 which is swingable in the rear direction from the front portion of the injection cylinder and suspended by being forwardly biased, when in the lowered position, and In the trigger type liquid ejection container that is separated at the raised position and that allows the trigger rearward pulling operation only at the detached position,

Set up freely,
When the stopper member 10 is lowered, the rear surface of the second engagement plate 14 projecting rearward from the upper part of the trigger comes into contact with the front surface of the engagement projection 12a, and when the stopper member is raised, the second engagement plate 14 and the engagement projection 12a cannot be engaged. Formed.
[0007]
As a second means, the front face of the reinforcing plate 3a is positioned forward of the front end face of the cylinder 6 together with the first means.
[0008]
As a third means, the first or second means is provided, and the reinforcing plates 3a are paired on the left and right sides in parallel with a small gap between the left and right sides of the lower surface of the injection cylinder 3 and the upper surface of the cylinder 6.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
The drawings will be described below. First, a conventionally known structure will be briefly described. 1 is a container body, 2 is a mounting cylinder fitted to the mouth and neck of the container body, and the main cylinder is raised from the inside of the mounting cylinder. The injection cylinder 3 protrudes forward. The front end of the injection cylinder is a fitting cylinder 4, and a nozzle cap 5 is rotatably fitted to the outer surface of the fitting cylinder. Further, the cylinder 6 is provided so as to be inclined downward and forward from the lower surface of the rear portion of the main cylinder surface of the injection cylinder. Further, the trigger 7 is suspended from the front portion of the injection cylinder 3 so as to be swingable in the rear direction, and the pushing plate 9 for the plunger 8 that is fitted forwardly into the cylinder is projected from the rear surface of the trigger. .
[0011]
Further, the sliding vertical plate 11 of the stopper member 10 projecting backward from the first engaging plate 12 from the lower end of the sliding vertical plate 11 is inserted into the fitting cylinder 13 through the fitting hole 13 formed in the manual vertical plate as shown in FIG. It hangs freely on the outer surface of the base 4 so as to freely move up and down. Further, an engaging element 5a shown in FIG. 3 is projected from a part of the rear end surface of the nozzle cap 5 and is loosely inserted into the fitting hole 13, and the engaging element 5a is turned by rotating the nozzle cap 5. When it moves along the outer surface of the fitting cylinder 4 and is positioned above the upper surface of the fitting cylinder as shown in FIG. 4, the sliding vertical plate 11 is pushed up, and the engaging element 5a is inserted into the fitting cylinder 4 as shown in FIG. The sliding vertical plate 11 is provided so as to descend by moving to the outer side.
[0012]
In the present invention, when the sliding vertical plate 11 is pushed up as shown in FIG. 4, the first engagement plate 12 protruding rearward from the lower end of the sliding vertical plate does not contact the lower surface of the front portion of the injection cylinder 3. The sliding vertical plate 11 was provided short so as to be close to each other. The first engaging plate 12 hangs from the lower surface of the rear portion of the engaging protrusion 12a. As shown in FIG. 4, when the stopper member 10 is raised, the trigger 7 can swing backward. That is, as shown in FIG. 1, when the stopper member is lowered, the second engaging plate 14 protruding from the rear surface of the trigger 7 is in contact with the front surface of the engaging protrusion 12a, so that the trigger cannot swing backward. However, as shown in FIG. 4, the engaging protrusion 12a moves upward as the stopper member 10 is raised, so that the second engaging plate 14 and the engaging protrusion 12a are not engaged even when the trigger 7 is swung. Therefore, the plunger push-in plate 9 provided below the second engagement plate 14 pushes the plunger 8 against the urging force inside the cylinder, and ejects liquid from the nozzle cap through the injection cylinder by cylinder pressurization. To do.
[0013]
As shown in FIG. 3, a reinforcing plate 3a for connecting the lower surface of the injection cylinder 3 and the upper surface of the cylinder 6 is provided, and the rear surface of the engaging projection 12a is in contact with the front surface of the reinforcing plate so as to be movable up and down. The front surface of the reinforcing plate is parallel to the sliding vertical plate 11 of the stopper member 10.
[0014]
The front surface of the reinforcing plate is positioned in front of the front end of the cylinder 6.
[0015]
In the illustrated example, the reinforcing plates are provided as a pair on the left and right sides in parallel between the left and right side portions of the lower surface of the injection cylinder and the upper surface of the cylinder with a small gap between them, and as shown in FIG. The guide 12b protrudes rearward from the middle portion in the direction and is fitted into the small gap so as to be movable up and down.
[0016]
Further, in the illustrated example, the projecting plate 15 is projected in a flange shape from the outer surface portion excluding the lower surface of the fitting cylinder 4, and the longitudinal grooves 16, 16 are formed on the inner surface forward from the left and right outer ends of the projecting plate. As shown in FIG. 5, the left and right side portions of the sliding vertical plate 11 are fitted into the vertical grooves so as to be movable up and down.
[0017]
In the above configuration, when the stopper member 10 is lowered as shown in FIG. 1, the rear end surface of the second engagement plate 14 protruding rearward from the upper portion of the trigger 7 even if the trigger 7 is swung back. However, since it is in contact with the front surface of the engaging protrusion 12a and the rear surface of the first engaging plate 12 is in contact with the front surface of the reinforcing plates 3a, 3a, it cannot be swung back, and therefore the plunger push-out protruding backward from the trigger The plate 9 is also unable to push the plunger 8. At this time, the nozzle hole 5b of the nozzle cap is closed.
[0018]
Next, when the nozzle cap 5 is rotated and the engaging element 5a is moved to the upper surface of the fitting cylinder 4, the sliding vertical plate 11 is fitted into the vertical grooves 16 and 16 of the guide plates 17 and 17 on both left and right sides. The rear surface of the engaging projection 5a is in contact with the front surfaces of the reinforcing plates 3a and 3a so as to be movable up and down, so that the first engaging plate 12 of the stopper member 10 is pushed upward. The trigger cylinder 7 is pulled up to the vicinity of the lower surface of the injection cylinder 3, and thus the trigger 7 can be swung back. At this time, the nozzle hole 5b is opened, so that the liquid in the injection cylinder is ejected through the nozzle hole.
[0019]
【The invention's effect】
The present invention has the above-described configuration. When the stopper member 10 is raised by the rotation of the nozzle cap 5 as described in claim 1, the first engagement plate 12 of the stopper member does not contact the lower surface of the injection cylinder 3. Since they are provided close to each other, the height of the stopper member can be made shorter than that of the conventional example described above, and therefore the molding material for the stopper member can also be reduced. Therefore, the nozzle cap for moving the stopper member up and down can be easily turned.
[0020]
In addition, since the lower surface of the injection cylinder 3 and the upper surface of the cylinder 6 are connected by the reinforcing plate 3a, the integrity of the injection cylinder 3, the cylinder 6 and the main cylinder can be improved, and the rear surface of the engagement protrusion 12a is directed to the front end surface of the cylinder 6. Since the engagement is disabled, the rear surface of the first engagement plate 12 or the engagement protrusion 12a is not pressed against the front surface of the cylinder 6 when the trigger is pulled, and the cylinder is not adversely affected. Further, since the front surfaces of the reinforcing plates 3a and 3a are provided in parallel with the sliding vertical plate 11 of the stopper member, the frictional resistance when the stopper member 10 moves up and down can be reduced.
[0021]
As described in claim 2, by positioning the front surface of the reinforcing plate 3a in front of the front end surface of the cylinder 6, the rear surface of the first engaging plate 12 or the engaging projection 12a is pressed against the front surface of the cylinder 6 when the trigger is pulled. Can be reliably prevented.
[0022]
According to the third aspect of the present invention, it is possible to prevent the first engaging plate 12 from being laterally displaced with respect to the front surfaces of the reinforcing plates 3a and 3a by the guide 12b.
[0023]
By making it like Claim 4, the vertical movement of the stopper member 10 by nozzle nozzle 5 rotation becomes easy.
