Description

本発明は、トリガー式液体噴出器に関するもので、該噴出器の構造を大きく変更することなしに内容物の均一な噴射を可能にしようとするものである。   The present invention relates to a trigger type liquid ejector, and is intended to enable uniform injection of contents without greatly changing the structure of the ejector.

黴取り剤や洗剤、衣料用糊剤、住居用ワックス、整髪剤、芳香剤等の液体を入れた容器においては操作レバーの牽曳によって容器内の液体を霧状あるいは泡状にして噴出させるトリガー式の噴出器が多用されており、これにより液体の効率的な供給を可能にしている。   Trigger that sprays liquid in the container in the form of mist or foam by checking the operation lever in containers containing liquids such as wrinkle remover, detergent, clothing paste, residential wax, hair conditioner, fragrance, etc. The type of ejector is frequently used, which enables an efficient supply of liquid.

かかるトリガー式液体噴出器は、噴射ノズルを取り付けたボディに、液体の吸引、加圧、圧送を司るポンプ機構を組み込み、該ポンプ機構を、ばね部材にて弾性支持された操作レバーによって駆動する仕組みになっており、近年に至っては、廃棄時における構成部材の分別を不要にして資源の有効活用を図るために、各構成部材を全て合成樹脂にて成形したものも提案されている（例えば特許文献１参照）。

In recent years, in order to make effective use of resources without the need for separation of components at the time of disposal, it has also been proposed that all components are molded from synthetic resin (for example, patents). Reference 1).
Japanese Patent Laid-Open No. 11-290731

ところで、従来型の液体噴出器は、操作レバーの牽曳速度によって液体の噴射形態が変動するため、液体を均一な霧の状態で噴射させるのは困難であった。   By the way, the conventional liquid ejector has difficulty in ejecting the liquid in a uniform mist state because the liquid ejection form varies depending on the check speed of the operation lever.

この点に関しては、規定の圧力でもって弁体を開放して加圧に係る液体を噴出させる蓄圧式の噴出器についての提案がなされているが、液体噴出器を蓄圧式に変えるには設計変更や製造ラインの改造を余儀なくされる。   With regard to this point, a proposal has been made for an accumulator-type ejector that opens the valve body with a specified pressure and ejects the pressurized liquid, but the design change is required to change the liquid ejector to the accumulator type. And forced to remodel the production line.

本発明の課題は、設計変更や製造ラインの改造を伴うことなしに、液体の均一な噴射を可能とするトリガー式液体噴出器を提案するところにある。   An object of the present invention is to propose a trigger type liquid ejector that can uniformly inject liquid without design change or modification of a production line.

本発明は、操作レバーを繰り返し牽曳して容器内の液体を吸引、加圧、圧送するポンプと、このポンプを一体的に備え該ポンプによって加圧、圧送された液体を通過させる送給経路を有するボディと、このボディの送給経路の末端に配置され送給経路を通って圧送された液体を外界に向けて噴射する噴射ノズルとを備えたトリガー式液体噴出器であって、
前記ボディの送給経路内に、該送給経路を閉塞状態に常時保持し、液体の圧力が規定圧力に達したときにのみに該送給経路を開放する蓄圧弁を設け、
前記蓄圧弁は、送給経路内で該経路に沿って往復移動可能な弁体と、この弁体の開口から内部空間へと入り込み送給経路内の弁座に弁体の先端部を押し当てて該経路を閉塞状態に保持する一方、規定圧力に達したときにのみ弁座から弁体を離反させる反発力を有する弾性部材と、送給経路内に設置され、弁体の内部空間に弾性部材とともに入り込んで該弁体の移動を誘導するカートリッジ式のガイドと、を有することを特徴とするトリガー式液体噴出器である。 The present invention includes a pump that repeatedly checks the operation lever to suck, pressurize, and pressurize the liquid in the container, and a feeding path that integrally includes the pump and allows the liquid pressurized and pumped by the pump to pass therethrough. A trigger type liquid ejector comprising: a body having a nozzle; and an injection nozzle that is disposed at an end of a supply path of the body and injects a liquid pumped through the supply path toward the outside,
In the body supply path, a pressure accumulating valve that always keeps the supply path in a closed state and opens the supply path only when the pressure of the liquid reaches a specified pressure is provided,
The accumulator valve is capable of reciprocating along the path in the feeding path, and enters the internal space from the opening of the valve body and presses the tip of the valve body against the valve seat in the feeding path. The elastic member having a repulsive force that separates the valve body from the valve seat only when the specified pressure is reached, and the elastic member that is installed in the feed path and elastically holds in the internal space of the valve body. A trigger type liquid ejector comprising: a cartridge type guide that enters with a member to guide the movement of the valve body .

また、前記ポンプは、液体の吸引、排出開口を有しボディにつながるシリンダーと、このシリンダーの内側にスライド可能に設置され操作レバーの牽洩にて往復移動するピストンにて構成し、前記シリンダーには、ピストンの往動端への移動により開放される開孔と、この開孔及び容器の空気置換口とをつなぎ、空気の貯留空間を形成する緩衝部を設けることができる。   The pump is composed of a cylinder that has a suction and discharge opening for liquid and is connected to the body, and a piston that is slidably installed inside the cylinder and reciprocates when the operating lever leaks. Can be provided with a buffer portion that connects an opening that is opened by movement of the piston to the forward end and the opening and the air replacement port of the container to form an air storage space.

ボディの送給経路内に蓄圧弁を挿入、配置するだけで蓄圧式の液体噴出器に変更することができ、設計を変更するなどの余計な手間をかけることなしに液体の均一な噴射が可能となる。   By simply inserting and placing an accumulator valve in the body's feed path, it can be changed to an accumulator-type liquid ejector, and liquid can be uniformly ejected without extra effort such as changing the design. It becomes.

ピストンの往動端への移動によって開放される開孔と容器の空気置換口との間に空気の貯留空間を設けると、液体の噴射量（吐出量）を増加させるべくピストンのストロークを大きくしてもシリンダーの断面積を変更する必要がないため操作レバーの牽曳が重くなることはない（操作性が改善される）。   If an air storage space is provided between the opening opened by the movement of the piston to the forward end and the air replacement port of the container, the stroke of the piston is increased to increase the liquid injection amount (discharge amount). However, since there is no need to change the cross-sectional area of the cylinder, the check of the operating lever does not become heavy (operability is improved).

以下、図面を用いて本発明をより具体的に説明する。
図１は本発明にしたがうトリガー式液体噴出器の実施の形態を示したものであり、図における１は液体噴出器のボディである。このボディ１は送給経路sを有するボディ本体１ａと、空気置換口ｈを有し吸引管ｋにつがるインテイク１ｂからなる。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows an embodiment of a trigger type liquid ejector according to the present invention, and 1 in the figure is a body of the liquid ejector. The body 1 includes a body main body 1a having a feeding path s and an intake 1b having an air replacement port h and connected to a suction pipe k.

また、２はボディ１に一体的につながるポンプである。このポンプ２はボディ１の送給経路sに通じる開孔ｓ１及びインテイク１ｂの空気置換口ｈにつながる開孔ｓ２を有するシリンダー２ａと、このシリンダー２ａ内にて往復移動可能なピストン２ｂと、このピストン２ｂをシリンダー２ａ内で弾性支持するスプリング２ｃからなる。上記開孔ｓ２はシリンダー２ａの底部に設けられるもので、ピストン２ｂの復動端位置にて該ピストン２ｂの摺動リップ部により空気置換口ｈ及び開孔ｓ２を通した液漏れを防止するようにシールされている。 Reference numeral 2 denotes a pump integrally connected to the body 1. And the pump 2 is a cylinder 2a having an opening s 2 lead to air displacement opening h of apertures s 1 and Intake 1b leading to the feeding path s of the body 1, and reciprocally movable piston 2b in the cylinder 2a in The spring 2c elastically supports the piston 2b in the cylinder 2a. The apertures s 2 are those provided at the bottom of the cylinder 2a, prevents leakage through the air displacement ports h and opening s 2 by sliding the lip portion of the piston 2b at the backward end position of the piston 2b It is sealed to do.

３はボディ１の送給経路sの末端に配置され該送給経路sを通って圧送された液体を外界へ向けて噴射する噴射ノズル、４はボディ１に枢支軸を介して揺動可能に保持されピストン２ｂを押圧する操作レバー、５はボディ１をねじあるいはアンダーカットの如き係合手段にて容器の口部に固定保持するキャップ、６はボディ１の送給経路ｓ内に配置された蓄圧弁である。   3 is an injection nozzle that is arranged at the end of the feeding path s of the body 1 and jets the liquid pressure-fed through the feeding path s toward the outside, and 4 can swing on the body 1 via a pivot shaft. An operation lever 5 that holds the body 1 and presses the piston 2b, 5 is a cap that fixes and holds the body 1 to the mouth of the container by an engaging means such as a screw or undercut, and 6 is disposed in the feeding path s of the body 1. Accumulator valve.

蓄圧弁６は後端部にて開口する内部空間ｐを有し、送給経路s内で該経路sに沿って移動可能な弁体６ａと、この弁体６ａの開口６ａ′から内部へと入り込み送給経路ｓ内の弁座ｖに弁体６ａのシール部ｖ′を押し当てて該経路sを閉塞状態に保持する一方、規定圧力に達したときにのみ弁座ｖから弁体６ａを離反させる反発力を有する弾性部材６ｂと、送給経路s内に配置され、弁体６ａの内部空間ｐに弾性部材６ｂとともに入り込んで弁体６ａの移動を誘導するカートリッジ式のガイド６ｃからなる。弁体６ａの上部外周面には送給経路ｓ内周面に密に接する摺動リップ部が形成されており、弾性部材６ｂは、ステンレス等の金属製のスプリングや合成樹脂製のスプリングが適用可能となっている。   The pressure accumulating valve 6 has an internal space p that opens at the rear end, and within the feeding path s, is movable along the path s, and from the opening 6a 'of the valve body 6a to the inside. The seal portion v ′ of the valve body 6a is pressed against the valve seat v in the entry / feed path s to hold the path s in a closed state, while the valve body 6a is moved from the valve seat v only when the specified pressure is reached. An elastic member 6b having a repulsive force for separating and a cartridge-type guide 6c that is disposed in the feeding path s and enters the internal space p of the valve body 6a together with the elastic member 6b to guide the movement of the valve body 6a. A sliding lip portion that is in close contact with the inner peripheral surface of the feeding path s is formed on the upper outer peripheral surface of the valve body 6a, and a metal spring such as stainless steel or a synthetic resin spring is applied to the elastic member 6b. It is possible.

上記の構成になる液体噴出器は、規定圧力に達する前の段階では図２（ａ）に示す状態にあるが、加圧に係る液体の圧力が規定圧力に達したときに図２（ｂ）に示す如く蓄圧弁６の弁体６ａが弁座ｖから離反するものであり、液体は操作レバー４の牽曳速度に係わりなく常に一定の状態で噴射されることになる。   The liquid ejector configured as described above is in the state shown in FIG. 2A before reaching the specified pressure, but when the pressure of the liquid related to pressurization reaches the specified pressure, FIG. As shown in FIG. 2, the valve body 6a of the pressure accumulating valve 6 is separated from the valve seat v, and the liquid is always ejected in a constant state regardless of the check speed of the operation lever 4.

弁体６ａが弁座ｖから離反する規定圧力は、弾性部材６ｂの反発力や弁体６ａに形成した摺動リップ部の送給経路ｓ内周面に対する摺動抵抗を変更することで調整することができる。   The specified pressure at which the valve body 6a is separated from the valve seat v is adjusted by changing the repulsive force of the elastic member 6b and the sliding resistance of the sliding lip formed on the valve body 6a with respect to the inner peripheral surface of the feed path s. be able to.

図３は本発明にしたがうトリガー式液体噴出器の他の実施の形態を示したものである。
このトリガー式液体噴出器は、先の実施の形態でポンプ２の内側に組み込まれていたステンレス製コイルスプリングに換えて樹脂製スプリングをポンプ２の外側に配置した液体噴出器に係わるもので、７は操作レバー４の牽曳に際してポンプ２のピストン２ｂを初期位置に復帰させる板ばね、８はシリンダー２ａの外側で空気の貯留空間を形成する環状の緩衝部である。この緩衝部８はシリンダー２ａを同心の内外２重構造とすることにより当該シリンダー間に形成されるもので、ピストン２ｂの往動端への移動により開放される開孔ｓ２と、この開孔ｓ２及び容器の空気置換口ｈとをつなぐようになっている。なお、当該シリンダー構造にあっては、内側シリンダーに形成される開孔ｓ２は当該シリンダー側面よりも上方に形成されている。 FIG. 3 shows another embodiment of the trigger type liquid ejector according to the present invention.
This trigger type liquid ejector relates to a liquid ejector in which a resin spring is arranged outside the pump 2 in place of the stainless steel coil spring incorporated inside the pump 2 in the previous embodiment. Is a leaf spring for returning the piston 2b of the pump 2 to the initial position when the operation lever 4 is depressed, and 8 is an annular buffer portion that forms an air storage space outside the cylinder 2a. The buffer portion 8 intended to be formed between the cylinder by the cylinder 2a and concentric inner and outer double structure, the opening s 2 which is opened by the movement of the forward end of the piston 2b, the opening s 2 and the air replacement port h of the container are connected. Incidentally, in the said cylindrical structure is opening s 2 formed inside the cylinder is formed above the said cylinder side.

かかる構成の噴出器においても、操作レバー４の牽曳動作において液体の圧力が規定圧力に達したときに初めて蓄圧弁６の弁体６ａが弁座ｖから離反し液体は操作レバー４の牽曳速度に係わりなく常に一定の状態で噴射されることになる。   Also in the ejector having such a configuration, the valve body 6a of the pressure accumulating valve 6 is separated from the valve seat v for the first time when the pressure of the liquid reaches the specified pressure in the check operation of the operation lever 4, and the liquid is checked by the operation lever 4. The fuel is always injected in a constant state regardless of the speed.

トリガー式液体噴出器のポンプ２については、液体の噴射量を増大させるためにはピストン２ｂのストロークを単に大きくすることが考えられるが、トリガー式液体噴出器のストロークは空気置換口ｈの位置が動かせないため開孔ｓ２の位置がおのずと固定されてしまい、これによりピストン２ｂのストロークを延長した場合、開孔ｓ２はシール不能となり空気置換口ｈ及び開孔ｓ２を通じてシリンダー２ａ内に液体が流入するおそれが生じることからピストン２ｂのストロークの延長可能な距離が制限される。このような状況で噴射量を増大させるにはシリンダー２ａの断面積を大きくする対応しか採り得ず、結果的に操作レバー４の牽曳が重くなるのが避けられない。本発明は、シリンダー２ａを同心の内外２重構造とし、該シリンダー２ａの開孔ｓ２と空気置換口ｈとの相互間を緩衝部８でつないでおくことにより開孔ｓ２の位置を操作レバー４側にずらすことを可能としたものであり、これによりストロークを大きくすることができるとともに、空気置換口ｈ及び開孔ｓ２を通じてシリンダー２ａ内に内容物が流入するのを防止することが可能となる。シリンダー２ａを同心の内外２重構造とし、この緩衝部８を設けることで操作性を劣化させることなしにピストン２ｂのストロークを約２倍程度まで延長することが可能となる。 For the pump 2 of the trigger type liquid ejector, it is conceivable to simply increase the stroke of the piston 2b in order to increase the amount of liquid injection. However, the stroke of the trigger type liquid ejector is such that the position of the air replacement port h is position for not move opening s 2 is will be fixed naturally, thereby when extended stroke of the piston 2b, liquid opening s 2 is sealed crippled becomes the cylinder 2a through air displacement ports h and opening s 2 Is likely to flow in, the distance over which the stroke of the piston 2b can be extended is limited. In order to increase the injection amount in such a situation, it is only possible to take measures to increase the cross-sectional area of the cylinder 2a. As a result, it is inevitable that the check of the operation lever 4 becomes heavy. The present invention is a cylinder 2a and concentric inner and outer double structure, manipulate the position of the aperture s 2 by previously connecting between each other and opening s 2 and the air replacement port h of the cylinder 2a in the buffer section 8 is obtained by allowing the shift lever 4 side, thereby it is possible to increase the stroke, that the contents in the cylinder 2a through air displacement ports h and opening s 2 is prevented from flowing It becomes possible. By providing the cylinder 2a with a concentric inner / outer double structure and providing the buffer portion 8, the stroke of the piston 2b can be extended to about twice without deteriorating the operability.

蓄圧弁６は図５に示すように弁体６ａにおける摺動リップを削除して弾性部材６ｂの抵抗のみで蓄圧する構造にしてもよいし、図６に示すように弁体６ａの摺動リップを削除するとともにスプリングに換えて弁体６ａと一体になる弾性部材６ｂ′を設けてもよく（図示の参考例では上方に向け凹となる湾曲板状の弾性部材）、この点に関する構成は種々に変更することが可能で、図示のものには限定されない。 The pressure accumulating valve 6 may have a structure in which the sliding lip in the valve body 6a is deleted as shown in FIG. 5 to store pressure only by the resistance of the elastic member 6b, or the sliding lip of the valve body 6a as shown in FIG. May be provided and an elastic member 6b 'integrated with the valve body 6a may be provided in place of the spring (a curved plate-like elastic member that is concave upward in the illustrated reference example ). However, the present invention is not limited to the illustrated one.
