本案はトリガー式の液体噴出器に係る。 The present invention relates to a trigger type liquid ejector.
【０００２】[0002]
実開平1-69658 号が示すように、容器体口頸部に嵌合させる装着筒を起立筒部 下端に有して、起立筒部中間からシリンダを、かつ上端から射出筒を、それぞれ 前方突出し、射出筒前部に枢着させて垂下するトリガーの上部後面へ、上記シリ ンダ内へ前方付勢して嵌合させたピストンから前方突出するピストン棒の前端面 を係合させると共に、上記装着筒の上部内へ下端を、かつピストン外面が前限位 置で対向し、かつ後方位置でピストン外面から外れるシリンダ壁部分に上端を、 それぞれ開口する通気路を穿設し、該通気路を通気性を有し、かつ非通水性の耐 水性シートで遮断させた、トリガー式液体噴出器が知られている。 As shown in Japanese Utility Model Laid-Open No. 1-69658, a mounting cylinder to be fitted into the neck of the container body is provided at the lower end of the standing cylinder, and the cylinder is projected from the middle of the standing cylinder and the injection cylinder is projected from the upper end. , The front end face of the piston rod protruding forward from the piston fitted forwardly into the cylinder is engaged with the rear face of the upper part of the trigger which is pivotally attached to the front part of the injection cylinder and hangs down, and is mounted as described above. Ventilation passages are formed by opening the lower end into the upper part of the cylinder, the piston outer surface facing in the front position, and the upper end on the cylinder wall part that deviates from the piston outer surface at the rear position. A trigger type liquid ejector is known, which has a property of being blocked by a water-resistant sheet that is impermeable to water.

上記従来の液体噴出器は、トリガー操作による噴出液体置換のための外気吸入 を上記通気路およびシートを介して行うものであるが、ピストンの前後両端部を シリンダ内壁面へ圧接させて、ピストン後退時にだけ通気路と外気とが連通する よう設けている。しかし、その噴出器を装着する容器体内が温度変化等により高 圧化することがあり、該状態からのトリガー操作で一旦吐出弁が開くと、その閉 塞が不完全となって、そのためノズル孔から液体が漏れることがあった。該漏れ は、その漏れにより容器体内圧力が低下すると共に停止し、吐出弁の閉塞も確実 となるが、その漏れた液体がノズル周辺を汚すこととなるほか、そのような液漏 れが度重なることで、液体乾燥の都度、液体成分が蓄積されてノズル孔が目塞り することがあった。 The conventional liquid ejector described above sucks the outside air for replacing the ejected liquid by a trigger operation through the air passage and the seat.However, the front and rear end parts of the piston are pressed against the inner wall surface of the cylinder to retreat the piston. The ventilation passage is designed to communicate with the outside air only at times. However, the pressure inside the container in which the ejector is mounted may increase due to temperature changes, etc., and once the discharge valve is opened by a trigger operation from this state, the closing of the discharge valve becomes incomplete, and therefore the nozzle hole Liquid could leak from. The leak stops the internal pressure of the container when it leaks and stops the discharge valve securely, but the leaked liquid contaminates the area around the nozzle and such a leak frequently occurs. As a result, every time the liquid is dried, the liquid component may be accumulated and the nozzle hole may be clogged.
【０００４】 本案は上記外気吸入路を改変して内圧排出兼用路とすることで、上記欠点を除 去するものである。The present invention eliminates the above-mentioned drawbacks by modifying the outside air intake passage so as to also serve as an internal pressure discharge passage.

容器体口頸部嵌合用の装着筒３を下端に付設した、大径筒部５の上壁後部を貫 通して吸上げ筒を起立し、該筒の中間部からシリンダ20を、かつ上端から射出筒 21を、それぞれ前方突出し、射出筒前部に枢着させて垂下するトリガー35の上部 後面へ、上記シリンダ内へ前方付勢させて嵌合させたピストン37から前方突出す るピストン棒38前端面を係合させたトリガー式液体噴出器において、上記大径筒 部５上壁の前部に装着筒３内と外気とを連通する通気路44を穿設すると共に、上 記大径筒部５の筒孔が形成する、装着筒３内から通気路44にいたる通路を、通気 性かつ非通水性で耐水性を有するシート45で遮断した。 A suction cylinder is erected through the rear part of the upper wall of the large-diameter cylinder part 5, which has a mounting cylinder 3 for fitting the neck of the container body at the lower end, and stands up from the middle part of the cylinder to the cylinder 20 and from the upper end. Each of the injection cylinders 21 protrudes forward, and to the upper rear surface of the trigger 35 that is pivotally attached to the front part of the injection cylinder and hangs down, the piston rod 38 that protrudes forward from the piston 37 that is biased forward into the cylinder and fitted. In the trigger-type liquid ejector with the front end surface engaged, a ventilation passage 44 that communicates the inside of the mounting cylinder 3 with the outside air is bored in the front part of the upper wall of the large-diameter cylinder 5 and the large-diameter cylinder described above. The passage from the inside of the mounting cylinder 3 to the ventilation passage 44 formed by the cylindrical hole of the portion 5 is blocked by a sheet 45 having air permeability, water impermeability and water resistance.

図１が示す状態で、射出筒21は吐出弁25が、又通気路44は耐水性シート45が、 それぞれ閉塞しており、よって容器が倒れる等しても容器体内液体が漏れること はない。又温度変化等で容器体内液面上方の空気が膨張すると、上記耐水性シー トは通気性を有するから該シートおよび通気路44を通って外方へ排出される。更 にトリガー操作で容器体内液体が減少すると、上記通気路44および耐水性シート 45を通って外気が容器体内へ入り、負圧化を防止する。 In the state shown in FIG. 1, the discharge valve 25 of the injection cylinder 21 and the water resistant sheet 45 of the ventilation passage 44 are closed, so that the liquid in the container does not leak even if the container falls. Further, when the air above the liquid level in the container expands due to a temperature change or the like, the water resistant sheet has air permeability, and is discharged to the outside through the sheet and the air passage 44. Further, when the liquid in the container decreases due to the trigger operation, the outside air enters the container body through the air passage 44 and the water resistant sheet 45 to prevent negative pressure.

本案は既述構成とするもので、大径筒部５の上壁前部に装着筒３内と外気とを 連通する通気路44を穿設すると共に、大径筒部５の筒孔が形成する、装着筒３内 から通気路44にいたる通路を、通気性かつ非通水性で耐水性を有するシート45で 遮断したから、流通時および使用時を問わず、容器体内が高圧化することがなく 、よって既述従来例の場合のように、容器体内が高圧化したことに基因する液漏 れを防ぐことが出来、又液体噴出により容器体内液体が減少すれば外気が流入す るから、従来同様外気吸入路としても作用する効果がある。 The present invention is configured as described above, and a ventilation passage 44 that communicates the inside of the mounting cylinder 3 with the outside air is bored in the front portion of the upper wall of the large-diameter cylindrical portion 5, and the cylindrical hole of the large-diameter cylindrical portion 5 is formed. Since the passage extending from the inside of the mounting cylinder 3 to the ventilation passage 44 is blocked by the sheet 45 having air permeability, water impermeability and water resistance, the pressure inside the container can be increased during distribution and use. Therefore, as in the case of the above-described conventional example, it is possible to prevent liquid leakage due to the high pressure inside the container body, and if the liquid in the container decreases due to liquid ejection, the outside air flows in. As in the conventional case, it has an effect of acting as an outside air intake passage.
