【０００１】
【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】
例えば特開平 10‐146548号が示すように、容器体口頸部に嵌合させる装着筒から縦筒を起立させて、該縦筒上部から射出筒を前方突出し、該射出筒前部から揺動可能に垂下させたトリガーと、射出筒後部下方に付設されたシリンダ内へ一半部を嵌合させて外方突出するプランジャの先端部とを連結して、該トリガーの揺動で容器体内液体を上記縦筒から垂下された吸上げパイプを介してシリンダ内へ吸込み、かつ該シリンダ内液体をノズル取付け部材を介して射出筒前端に嵌合させたノズルから噴出可能とし、又そのノズルは回動可能としてその回動位置によって液体吐出路の開閉が可能に、かつノズル孔からの噴出液体は高速回転し乍ら噴出するよう設けられている。
【０００３】
【発明が解決しようとする課題】
上記のような液体噴出器は、通常縦筒下部内に吸込み弁を、縦筒中間部に設けたシリンダとの連通孔上方の縦筒上部内に吐出弁を、それぞれ設け、又射出筒前端部にノズル取付け部材を設けているが、このように個別に設けることは面倒であり、又吐出弁から射出筒前端のノズル孔までの距離が長くなるにつれて液体流出時の抵抗が増大するために液体噴出圧が低下し、更に吐出弁からノズル孔までの液体流路が長くなるにつれて、液体噴出後にその吐出弁からノズル孔までの液体流路部分内に残る液体量が増えることとなり、該残存液体が洩れ易くなる。
本発明は、吸込み弁体と吐出弁体とノズル取付け部とを備えた棒状部材を射出筒内へ嵌合させ、もって上記従来の欠点を除去するものである。
【０００４】
【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に嵌合させる装着筒から縦筒を起立させて、該縦筒上部から射出筒を前方突出し、該射出筒前部から揺動可能に垂下させたトリガーと、射出筒後部下方に付設されたシリンダ内へ一半部を嵌合させて外方突出するプランジャの先端部とを連結して、該トリガーの揺動操作で容器体内液体を上記縦筒から垂下させた吸上げパイプを介して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部へ嵌合させたノズルから噴出可能としたトリガー式液体噴出器において、
上記射出筒４内へ、前棒部12と後棒部13とを圧縮バネ片14で一体に連結形成した棒状部材11を、前棒部12は、後部外面から放射状に突設した係合子17先端を射出筒の筒壁内面へ圧接固定させて、かつ後棒部13は、後端に付設した吸込み弁体18を上記射出筒後壁に穿設した吸込み弁孔15へ圧接し吸込み弁19を形成させて嵌合させ、更に前棒部12の前部外面へ、ノズル前壁5aから後方突設した内筒5bを嵌合させることで、該棒状部材外面と、射出筒４およびノズル内筒5bとの間に、上記吸込み弁孔15とノズル前壁5a中心に穿設したノズル孔5cとを連通する液体通路16を形成し、前棒部12の中間部から前外方へ拡開突設したスカート状の弾性弁体21の外周を液体通路壁面へ圧接させて吐出弁22とし、
更に上記吸込み弁19と吐出弁22との間の液体通路部分とシリンダ内とを連通させてシリンダに対する液体出入路26とした。
【０００５】
第２の手段として、上記第１の手段を有すると共に前棒部12の前部外周面とノズル内筒の内面との間の液体通路部分の前半部と後半部とを、前棒部12外面に穿設した第１溝部23と内筒内面に穿設した第２溝部24とのいずれかの一方と他方とで形成して、
該液体通路部分は、前棒部12に対する内筒5bの回動により連通および遮断が自在に形成した。
【０００６】
【発明の実施の形態】
まず従来公知の構造部分について簡単に説明すると、１は容器体口頸部に嵌合させる装着筒で、該装着筒からは縦筒２を起立し、該縦筒前面からはシリンダ３が、又縦筒上端からは射出筒４が、それぞれ前方突出させてあり、射出筒前端にはノズル５を嵌合させている。射出筒前部からはトリガー６が前後方向への揺動が可能に垂下されており、該トリガー上部にはシリンダ内へ後部を嵌合させたプランジャ７前端を連結し、又そのトリガーを板バネ８で前方付勢させている。尚９は縦筒２下部から垂設された吸上げパイプである。
本発明にあっては、上記射出筒４内へ、合成樹脂製の棒状部材11を嵌合させた。
【０００７】
棒状部材は、前棒部12と後棒部13とを圧縮バネ片14で一体に連結しており、前棒部12の前部外面へ、キャップ状に形成したノズル５の前壁5aから後方突設した内筒5bを嵌合させ、該棒状部材の外面と射出筒４および上記内筒5bの内周面との間に、射出筒後壁を形成する縦筒部分に穿設した吸込み弁孔15と、ノズル前壁中心に穿設したノズル孔5cとを連通する液体通路16を形成している。又前棒部12の後部外面から放射状に数個の係合子17を突出し、それ等先端を射出筒孔内面へ圧接させて該前棒部を射出筒内へ固定しており、このように固定させることで、後棒部13の後端に付設した吸込み弁体18を既述吸込み弁孔15の前面へ、圧縮バネ片14の付勢により圧接させて吸込み弁19を形成している。該後棒部は横断面十字形状等に形成して液体通路形成溝20を縦設しており、又圧縮バネ片の付勢に抗して前進し、又その付勢により後退可能である。
【０００８】
前棒部12はその中間部から前外方へ拡開させてスカート状の弾性弁体21を突出しており、該弁体外周を液体通路外壁面へ圧接させて吐出弁22を形成している。図示例ではノズル内筒5bの外周部後端から薄肉筒部5dを射出筒の前部内壁面へ圧接させて突出し、その薄肉筒部内面へ上記弾性弁体外周を圧接するが、その薄肉筒部を設けないで、弾性弁体外周を射出筒内壁面へ圧接させて吐出弁を形成してもよい。
【０００９】
前棒部12の前部外周面とノズル内筒5bの内面との間の液体通路部分は、それ等外周面、又は内周面の一方に形成した溝だけで形成してもよいが、図示例ではその前半部と後半部とを、前棒部12外面に穿設した第１溝部23と、内筒5b内面に穿設した第２溝部24とのいずれかの一方で形成し、ノズル５を回動させることで図示のようにそれ等両溝部を連通させたり、又遮断させることが可能とする。又前棒部前端面とノズル前壁5aの後面との間の液体通路部分は、前棒部の前端面ないし前壁後面のいずれかへ公知のスピン溝25を穿設することで形成する。これ等は既述従来例において、ノズル取付け部材とノズルとが形成していた液体通路部と同様に形成している。尚そのスピン溝は、噴霧器として使用する場合にだけ設けるもので、水鉄砲状に液体噴出させる場合は、通常の溝とする。
【００１０】
上記射出筒内の液体通路16のうち、吸込み弁19から吐出弁22までの部分とシリンダ３内とを液体出入路26で連通させる。図示例では射出筒後端とシリンダ後端部との間にその液体出入路を形成している。
上記構成とした液体噴出器を容器体に取付け、数回トリガー６を揺動操作させてシリンダ内に液体を吸込ませた状態から、トリガーを引寄せすると、プランジャ７が後退してシリンダ内液体は加圧され、よって液体出入路26を通って射出筒内の液体通路16に入り、吐出弁22を通り、更に第１溝部23，第２溝部24，スピン溝25を通って高速回転しながらノズル孔5cから噴出される。トリガーを離すと板バネ８の付勢によりトリガーおよびプランジャ７が前進し、シリンダ３および液体通路16内が負圧化するため、吸込み弁19が開いて容器体内液体が吸上げパイプ９および液体出入路26を通り、シリンダ内へ吸込みされる。以後トリガー操作の反復によりシリンダ内液体をノズル孔から噴出し、又シリンダ内へ液体吸込みすることが出来る。
【００１１】
【発明の効果】
本発明は既述構成とした棒状部材11を射出筒４内へ嵌合させて、吸込み弁19と吐出弁22とを形成するから、従来のように縦筒２内へそれ等両弁を別々に形成する面倒がなく、又吐出弁22は前棒部12の中間部に付設した弾性弁体21の外周を液体通路外壁面へ圧接させて形成するから、該吐出弁を射出筒前端へ嵌合させたノズルのノズル孔5cまでの距離を短かくでき、よってそのノズル孔から噴出する液体圧の低下を少くすることが出来、従って又液体噴出後にその吐出弁からノズル孔までの間に残存する液体を少くすることが出来る。更に前棒部12の前部外周面とノズル内筒5bの内面との間の液体通路部分の前半部と後半部とを、前棒部外面に穿設した第１溝部23と内筒5b内面に設けた第２溝部24とのいずれかの一方および他方で形成して、前棒部12に対するノズル内筒の回動でそれ等両溝部が連通、および遮断が自在に形成することで、同様の機能達成のために従来用いられていたノズル取付け部材を不要とすることが出来る。

As the ejection pressure decreases and the liquid flow path from the discharge valve to the nozzle hole becomes longer, the amount of liquid remaining in the liquid flow path portion from the discharge valve to the nozzle hole after liquid ejection increases, and the residual liquid Is likely to leak.
In the present invention, a rod-shaped member having a suction valve body, a discharge valve body, and a nozzle mounting portion is fitted into an injection cylinder, thereby eliminating the above-described conventional drawbacks.
[0004]

The outer periphery of the protruding skirt-like elastic valve body 21 is pressed against the wall surface of the liquid passage to form a discharge valve 22,
Further, the liquid passage portion between the suction valve 19 and the discharge valve 22 and the inside of the cylinder are connected to form a liquid inlet / outlet passage 26 for the cylinder.
[0005]
As the second means, the first half means and the rear half part of the liquid passage portion between the front outer peripheral surface of the front rod portion 12 and the inner surface of the nozzle inner cylinder are provided as the outer surface of the front rod portion 12. Formed by either one or the other of the first groove portion 23 drilled in the second groove portion 24 drilled in the inner cylinder inner surface,
The liquid passage portion was formed so as to be freely communicated and blocked by the rotation of the inner cylinder 5b with respect to the front rod portion 12.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
First, a conventional well-known structural part will be briefly described. Reference numeral 1 denotes a mounting cylinder to be fitted to a container body neck, and a vertical cylinder 2 is erected from the mounting cylinder, and a cylinder 3 is The injection cylinder 4 protrudes forward from the upper end of the vertical cylinder, and the nozzle 5 is fitted to the front end of the injection cylinder. A trigger 6 is suspended from the front of the injection cylinder so as to be swingable in the front-rear direction. A front end of a plunger 7 having a rear portion fitted into the cylinder is connected to the top of the trigger, and the trigger is connected to a leaf spring. 8 is biased forward. Reference numeral 9 denotes a suction pipe suspended from the lower portion of the vertical cylinder 2.
In the present invention, the rod-shaped member 11 made of synthetic resin is fitted into the injection cylinder 4.
[0007]
The rod-shaped member integrally connects the front rod portion 12 and the rear rod portion 13 with a compression spring piece 14, and is rearward from the front wall 5 a of the nozzle 5 formed in a cap shape on the front outer surface of the front rod portion 12. A suction valve that is fitted in the projecting inner cylinder 5b and is formed in a vertical cylinder portion that forms the rear wall of the injection cylinder between the outer surface of the rod-shaped member and the injection cylinder 4 and the inner peripheral surface of the inner cylinder 5b. A liquid passage 16 is formed to communicate the hole 15 with the nozzle hole 5c formed in the center of the nozzle front wall. Also, several engaging elements 17 project radially from the rear outer surface of the front rod portion 12, and the front rod portion is fixed to the inside of the injection cylinder by press-contacting the distal ends thereof to the inner surface of the injection cylinder hole. As a result, the suction valve body 18 attached to the rear end of the rear rod portion 13 is brought into pressure contact with the front surface of the suction valve hole 15 by the bias of the compression spring piece 14 to form the suction valve 19. The rear bar portion is formed in a cross-shaped cross section and the like and has a liquid passage forming groove 20 vertically, and can move forward against the biasing force of the compression spring piece and can be retracted by the biasing force.
[0008]
The front rod portion 12 is expanded from the middle portion to the front outer side to project a skirt-like elastic valve body 21, and the discharge valve 22 is formed by pressing the outer periphery of the valve body against the outer wall surface of the liquid passage. . In the illustrated example, the thin cylindrical portion 5d protrudes from the rear end of the outer peripheral portion of the nozzle inner cylinder 5b while being pressed against the front inner wall surface of the injection cylinder, and the outer periphery of the elastic valve body is pressed against the inner surface of the thin cylindrical section. The discharge valve may be formed by pressing the outer periphery of the elastic valve body against the inner wall surface of the injection cylinder without providing the valve.
[0009]
The liquid passage portion between the front outer peripheral surface of the front rod portion 12 and the inner surface of the nozzle inner cylinder 5b may be formed only by the outer peripheral surface or a groove formed on one of the inner peripheral surfaces. In the illustrated example, the front half and the rear half are formed by either one of a first groove 23 drilled in the outer surface of the front rod 12 and a second groove 24 drilled in the inner surface of the inner cylinder 5b. The two grooves can be communicated or blocked as shown in FIG. A liquid passage portion between the front end surface of the front rod portion and the rear surface of the nozzle front wall 5a is formed by drilling a known spin groove 25 on either the front end surface of the front rod portion or the rear surface of the front wall. These are formed in the same manner as the liquid passage portion formed by the nozzle mounting member and the nozzle in the conventional example described above. The spin groove is provided only when used as a sprayer, and is used as a normal groove when liquid is ejected in the form of a water gun.
[0010]
Of the liquid passage 16 in the injection cylinder, a portion from the suction valve 19 to the discharge valve 22 and the inside of the cylinder 3 are communicated with each other through a liquid inlet / outlet passage 26. In the illustrated example, the liquid inlet / outlet path is formed between the rear end of the injection cylinder and the rear end of the cylinder.
When the liquid ejector configured as described above is attached to the container body and the trigger 6 is swung several times to suck the liquid into the cylinder, the plunger 7 is retracted and the liquid in the cylinder is Thus, the nozzle enters the liquid passage 16 in the injection cylinder through the liquid inlet / outlet passage 26, passes through the discharge valve 22, and further rotates at high speed through the first groove portion 23, the second groove portion 24, and the spin groove 25. It is ejected from the hole 5c. When the trigger is released, the trigger and plunger 7 are moved forward by the urging of the leaf spring 8, and the cylinder 3 and the liquid passage 16 are negatively pressured. Therefore, the suction valve 19 is opened and the liquid in the container is sucked in and out of the suction pipe 9 and liquid. It passes through the path 26 and is sucked into the cylinder. Thereafter, the liquid in the cylinder can be ejected from the nozzle hole and the liquid can be sucked into the cylinder by repeating the trigger operation.
[0011]
【The invention's effect】
In the present invention, since the rod-shaped member 11 having the above-described configuration is fitted into the injection cylinder 4 to form the suction valve 19 and the discharge valve 22, these valves are separately provided in the vertical cylinder 2 as in the prior art. The discharge valve 22 is formed by pressing the outer periphery of the elastic valve body 21 attached to the intermediate portion of the front rod portion 12 to the outer wall surface of the liquid passage, so that the discharge valve is fitted to the front end of the injection cylinder. The distance to the nozzle hole 5c of the combined nozzle can be shortened, so that the drop in the liquid pressure ejected from the nozzle hole can be reduced, and therefore the remaining between the discharge valve and the nozzle hole after the liquid ejection. The amount of liquid to be used can be reduced. Further, a first groove portion 23 and an inner surface of the inner cylinder 5b which are formed in the outer surface of the front rod portion with a front half portion and a rear half portion of the liquid passage portion between the front outer peripheral surface of the front rod portion 12 and the inner surface of the nozzle inner tube 5b. It is formed by either one or the other of the second groove portions 24 provided on the front and the nozzle inner cylinder with respect to the front rod portion 12 so that both the groove portions can be freely communicated and blocked. The nozzle mounting member conventionally used for achieving the above function can be dispensed with.
