Description

本発明は、足踏み式の液体噴出装置に関し、とくには、吐出機構として、ポンプ式のディスペンサーを用いた足踏み式液体噴出装置を提供しようとするものである。   The present invention relates to a foot-operated liquid ejecting apparatus, and in particular, to provide a foot-operated liquid ejecting apparatus using a pump-type dispenser as a discharge mechanism.

従来、足踏み式の液体噴出装置としては、特許文献1に記載されるようなエアゾール式の容器が主流である。しかしながら、エアゾール式の容器は、内部に可燃性の液化石油ガスやジメチルエーテル等の噴射剤が含まれる場合があり、容器内にガスが残ったまま廃棄した場合、ごみ集積車や廃棄物処理施設で火災・爆発事故の原因となるおそれがある。このような事故を防ぐために、エアゾール式の容器を廃棄する場合には、内部の残留ガスを排出してから廃棄する必要があり、廃棄作業が面倒である。また、エアゾール式の容器は、容器内に充填されたガスの圧力を利用して内容液を噴射するものであるので、噴射ボタンを押している間は内容液が出続けてしまい、噴射量のコントロールが困難であり、また、エアゾール式の容器では、内容液噴射の際に起こり得るステムの押し込み不足等に起因して適正な噴出が行われず、内溶液に対して噴射剤の量を多く噴出してしまうことがあり、こうなると充填されたガスの圧力が不足して容器内に内容液が残ったまま使用できなくなる(残量が増大する)という不具合を生じる。   Conventionally, as a stepping type liquid ejecting apparatus, an aerosol type container as described in Patent Document 1 is mainly used. However, aerosol-type containers sometimes contain propellants such as flammable liquefied petroleum gas or dimethyl ether, and if they are discarded with the gas remaining in the container, they are used in garbage collection vehicles and waste disposal facilities. May cause fire or explosion. In order to prevent such an accident, when an aerosol-type container is to be discarded, it is necessary to discharge the residual gas inside the container, which is troublesome. In addition, the aerosol-type container uses the pressure of the gas filled in the container to inject the content liquid, so the content liquid continues to come out while the injection button is pressed, and the injection amount is controlled. In an aerosol-type container, proper ejection is not performed due to insufficient pushing of the stem that may occur when the liquid content is ejected, and a large amount of propellant is ejected from the internal solution. In such a case, the pressure of the filled gas is insufficient, and there is a problem that the liquid content remains in the container and cannot be used (the remaining amount increases).

このようなことから、吐出機構として、エアゾールに代えてポンプ式(蓄圧式)のディスペンサーを用いた足踏み式の液体噴出装置に対する要望がある。ポンプ式のディスペンサーであれば、エアゾール式の液体噴出装置のような加圧用の噴射剤を必要とせず、容器の廃棄処分に際して爆発等の危険がないため容器を穿孔する等の余計な手間がかからず、その上、ガスの圧力が不足して内容液を吐出できなくなるという不具合がないことから内容液が噴出されずに容器内に残る残量を減らすことができ、また、ポンプ式のディスペンサーは押圧ヘッドをワンプッシュして内容液を噴出できるため定量吐出が可能である。   For this reason, there is a demand for a stepping type liquid ejecting apparatus using a pump type (accumulation type) dispenser instead of aerosol as a discharge mechanism. If it is a pump-type dispenser, there is no need for a pressurizing propellant like an aerosol-type liquid ejection device, and there is no danger of explosion when disposing of the container, so there is an extra effort such as perforating the container. In addition, since there is no problem that the content liquid cannot be discharged due to insufficient gas pressure, the remaining amount remaining in the container without being ejected can be reduced, and a pump-type dispenser Since the content liquid can be ejected by one-pushing the pressing head, it is possible to discharge the liquid quantitatively.

特開2002−143733号公報JP 2002-143733 A

ところで、ポンプ式のディスペンサーを足踏み式の液体噴出装置に適用するにあたっては、該ディスペンサーを作動させるための機構として、梃子式の作動部材を足で踏み込んで揺動させることにより押圧ヘッドを押し込むものが挙げられるが、このような液体噴出装置にあっては、ディスペンサー付きの容器を装置にセットしていない状態では作動部材が自由に揺動してしまい移送中等における破損の原因になるとともに、容器を装置にセットするに際して作動部材が干渉する場合があり容器を装置にセットし難いという不具合がある。また、踏み込み後の作動部材の揺動姿勢を元に戻す付勢力を、押圧ヘッドの押し込みを元に戻すディスペンサーのばね部材の復元力で補わなければならないため、踏み込み後に作動部材が元の姿勢に復帰するのに時間がかかり、引き続いて内容液を噴出させたい場合にその要求に迅速に対応することができないという問題もある。   By the way, when a pump-type dispenser is applied to a foot-operated liquid ejecting apparatus, as a mechanism for operating the dispenser, there is a mechanism that pushes the pressing head by stepping on and swinging an insulator-type operating member with a foot. In such a liquid ejecting apparatus, the operation member may freely swing in a state where a container with a dispenser is not set in the apparatus, causing damage during transfer and the like. There is a problem that it is difficult to set the container in the apparatus because the operating member may interfere when the apparatus is set in the apparatus. In addition, the biasing force that restores the swinging posture of the actuating member after depressing must be compensated by the restoring force of the spring member of the dispenser that undoes the pressing of the pressing head, so the actuating member returns to its original posture after depressing. There is also a problem that it takes time to return, and it is not possible to quickly respond to the request when the content liquid is to be subsequently ejected.

この点に関しては、ディスペンサー付き容器を足踏み式の液体噴出装置にセットしていない状態(未使用状態)にて、押圧ヘッドを押し込むための作動部材を固定しておくための固定部材を別途設けて作動部材の自由な揺動を制限したり、作動部材を元の姿勢に復帰するためのばね部材をディスペンサーのばね部材とは別に設けて作動部材の揺動姿勢からの復帰を素早く行い得るようしたりすることも考えられるが、いずれにせよ部品点数の増加による製造コストの増大は避けられないものとなる。   In this regard, a fixing member is separately provided for fixing the operating member for pushing the pressing head in a state where the container with the dispenser is not set in the stepping type liquid ejecting apparatus (unused state). A spring member for limiting the free swinging of the actuating member or for returning the actuating member to the original posture is provided separately from the spring member of the dispenser so that the actuating member can be quickly returned from the swinging posture. In any case, an increase in manufacturing cost due to an increase in the number of parts is unavoidable.

それゆえ、本発明は、足踏み式の液体噴出装置の吐出機構としてポンプ式のディスペンサーを用いたものにつき、部品点数の増加を伴うことなく、移送中の作動部材の揺動に起因した破損を防止することができるとともに装置への容器のセットを容易に行うことができ、かつ引き続く内容液の吐出に対する要求にも迅速に対応可能な足踏み式液体噴出装置を提供することをその目的とする。   Therefore, the present invention uses a pump-type dispenser as a discharge mechanism of a stepping-type liquid ejecting device, and prevents damage caused by swinging of an operating member during transfer without increasing the number of parts. It is an object of the present invention to provide a foot-operated liquid ejecting apparatus that can easily set a container in the apparatus and can quickly respond to the demand for subsequent discharge of the content liquid.

本発明は上記課題を解決するためになされたものであり、本発明の足踏み式液体噴出装置は、容器本体の口部に装着したディスペンサーの押圧ヘッドを上下動させることにより、容器本体内の内容液を外部に噴出するディスペンサー付き容器と、ディスペンサー付き容器を上下に変位可能に保持するベース部材と、踏み込み用のペダルが設けられた一端部と、前記ディスペンサー付き容器の下方に位置する他端部との間にて前記ベース部材に揺動可能に軸支され、前記ペダルの踏み込み時に前記他端部により前記ディスペンサー付き容器を上方に押し上げ、変位させる作動部材と、前記ベース部材に固定され、前記ペダルの踏み込みによる前記ディスペンサー付き容器の上方への変位と協働して前記押圧ヘッドを押し込んで前記内容液を噴出させるハウジング部材と、を備え、前記ベース部材に、前記作動部材をペダル踏み込み前の初期姿勢となるよう付勢する一方、ペダル踏み込み時に弾性変形して前記作動部材の揺動を許容するベンド板を一体に形成してなることを特徴とするものである。   The present invention has been made to solve the above-described problems, and the foot-operated liquid ejection device of the present invention moves the press head of a dispenser attached to the mouth of the container body up and down to move the contents in the container body. A container with a dispenser that ejects liquid to the outside, a base member that holds the container with a dispenser in a vertically displaceable manner, one end provided with a pedal for stepping on, and the other end located below the container with a dispenser The base member is pivotally supported by the base member so that the container with the dispenser is pushed upward by the other end when the pedal is depressed, and is fixed to the base member, In cooperation with the upward displacement of the container with the dispenser by depressing the pedal, the pressure head is pushed in and the content liquid is ejected. A bend plate that biases the operating member into an initial posture before the pedal is depressed, and elastically deforms when the pedal is depressed to allow the operating member to swing. It is characterized by being formed integrally.

なお、本発明の足踏み式液体噴出装置にあっては、前記作動部材に、前記ベンド板からの付勢力を受けるとともに前記ペダル踏み込み時にベンド板からの付勢力をもって弾性変形する当接板を設けてなることが好ましい。   In the foot-operated liquid ejection device of the present invention, the operating member is provided with a contact plate that receives an urging force from the bend plate and elastically deforms with the urging force from the bend plate when the pedal is depressed. It is preferable to become.

さらに、本発明の足踏み式液体噴出装置にあっては、前記ベンド板を上方に向けて凸となるよう屈曲させてなることが好ましい。   Furthermore, in the foot-operated liquid ejection device of the present invention, it is preferable that the bend plate is bent so as to be convex upward.

本発明の足踏み式液体噴出装置にあっては、ディスペンサー付き容器をベース部材にセットする前の状態では、作動部材は、ベース部材に一体に形成されたベンド板によって略水平姿勢に付勢されているため、移送中等に足踏み式液体噴出装置が揺らされたり傾けられたりしても作動部材が揺動して破損することはない。また、ディスペンサー付き容器をベース部材にセットする際にも、作動部材はベンド板に付勢されてペダル踏み込み前の初期姿勢に維持されているため、作動部材がディスペンサー付き容器に干渉することがなく、ディスペンサー付き容器のセットをスムーズに行うことができる。実際にディスペンサー付き容器内の内容液を吐出するにあたっては、使用者が、ベース部材に揺動可能に支持された、足で踏むことのできるペダルを踏み込むと、作動部材がベンド板の付勢力に抗して揺動し、その作動部材の揺動と連動してディスペンサー付き容器が上方に押し上げられハウジング部材によって押圧ヘッドが下方に押し込まれるので、容器本体内の内容液が加圧、圧縮されて押圧ヘッドの噴出口より噴出する。このようにして内容液の吐出が行われた後に使用者がペダルの踏み込みを解放すると、作動部材はベンド板の付勢力により元の初期姿勢に戻されるので押圧ヘッドを元に位置に復帰させるばね部材の付勢力のみで作動部材を初期姿勢に戻す場合に比べて短時間に作動部材を初期姿勢に戻すことができ、引き続いて内容液の吐出の要求があった場合でもそれに迅速に対応することが可能である。   In the foot-operated liquid ejection device of the present invention, before the container with the dispenser is set on the base member, the actuating member is biased to a substantially horizontal posture by a bend plate formed integrally with the base member. Therefore, even if the foot-operated liquid ejection device is shaken or tilted during transfer or the like, the actuating member will not swing and be damaged. Further, when the container with a dispenser is set on the base member, the operating member is biased by the bend plate and is maintained in the initial posture before the pedal is depressed, so that the operating member does not interfere with the container with the dispenser. The container with the dispenser can be set smoothly. When actually discharging the liquid in the container with a dispenser, if the user steps on a pedal that can be stepped on with a foot supported by the base member so as to be able to swing, the actuating member will act on the urging force of the bend plate. The container with dispenser is pushed upward in conjunction with the swing of the operating member, and the pressing head is pushed downward by the housing member, so that the liquid content in the container body is pressurized and compressed. It ejects from the outlet of the pressing head. When the user releases the pedal after the discharge of the content liquid in this way, the operating member is returned to the original initial position by the urging force of the bend plate, so that the spring that returns the pressure head to the original position is restored. Compared to returning the operating member to the initial position with only the urging force of the member, the operating member can be returned to the initial position in a short time, and even if there is a subsequent request to discharge the content liquid, it can respond quickly. Is possible.

したがって、本発明の足踏み式液体噴出装置によれば、部品点数の増加を伴うことなく、移送中の作動部材の揺動に起因した破損を防止することができるとともに装置への容器のセットを容易に行うことができ、かつ引き続く内容液の吐出に対する要求にも迅速に対応することができる。   Therefore, according to the foot-operated liquid ejection device of the present invention, it is possible to prevent breakage due to the swinging of the operating member being transferred without increasing the number of parts and to easily set the container in the device. And can respond promptly to requests for subsequent discharge of the content liquid.

Reference numeral 24 denotes an overcap that is attached to the base cap 19 and can be removed during use.

ベース部材5は、ディスペンサー付き容器3を上下に摺動可能に保持するとともに作動部材11を揺動可能に支持するものであって、図3および図4に示すように、載置面G(図1参照)に沿って水平に延びるベース板26と、ベース板26の背面側にて立設されたベース筒28と、ベース筒28の内側でベース板26と平行に延びる支持板30と、ベース筒28の上端部に連設された外周壁32と、外周壁32の内側にて支持板30に立設された内周壁34とを備えている。内周壁34と支持板30の、内周壁34に囲まれた部分は、ディスペンサー付き容器3を上下に摺動可能に保持する保持部36を構成する。また、支持板30には作動部材11の他端部を挿通させるための開口h1が形成されるとともに該開口h1の近傍位置に作動部材11の後述する軸部を受ける一対の軸受38が設けられている。   The base member 5 holds the dispenser-equipped container 3 slidably up and down and supports the operating member 11 so as to be swingable. As shown in FIGS. 3 and 4, the mounting surface G (FIG. 1), a base plate 28 standing on the back side of the base plate 26, a support plate 30 extending parallel to the base plate 26 inside the base tube 28, and a base An outer peripheral wall 32 provided continuously with the upper end of the cylinder 28 and an inner peripheral wall 34 provided upright on the support plate 30 inside the outer peripheral wall 32 are provided. A portion of the inner peripheral wall 34 and the support plate 30 surrounded by the inner peripheral wall 34 constitutes a holding portion 36 that holds the dispenser-equipped container 3 slidably up and down. The support plate 30 is formed with an opening h1 through which the other end portion of the operating member 11 is inserted, and a pair of bearings 38 for receiving a shaft portion (described later) of the operating member 11 is provided in the vicinity of the opening h1. ing.

そして、ベース部材5には、開口h1に対応する位置にて支持板30から垂下する垂壁40の下端に底板42が連設されており、この底板42には作動部材11をペダル踏み込み前の初期姿勢となるよう付勢する一方、ペダル踏み込み時に弾性変形して作動部材11の揺動を許容する、上方に向けて凸となるよう屈曲したベンド板44が一体に延設されている。底板42の、ベンド板44の基部に対応する位置にはベンド板44を弾性変形し易くする一対の切り込みs1が形成されている。この例では、ベンド板44は、底板42から立ち上がって前方側に傾斜して延びる第1傾斜部分44aと該第1傾斜部分44aの先端から水平に延びる水平部分44bと該水平部分44bの先端から下方に向けて傾斜して延びる第2傾斜部分44cとで構成されるがこれに限定されない。なお、図3および図4において、符号h2は作動部材11をベース部材5に組み付ける際に作動部材11の他端部を通すためにベース筒28に形成された、支持板30の開口h1に通じる切欠きである。   The base member 5 is provided with a bottom plate 42 connected to the lower end of the hanging wall 40 that hangs down from the support plate 30 at a position corresponding to the opening h1. The bottom plate 42 is provided with the operating member 11 before the pedal is depressed. A bend plate 44 that is bent so as to protrude upward is integrally extended so as to be biased to an initial posture and elastically deform when the pedal is depressed to allow the operation member 11 to swing. A pair of cuts s1 that facilitate elastic deformation of the bend plate 44 are formed at positions corresponding to the base of the bend plate 44 of the bottom plate 42. In this example, the bend plate 44 rises from the bottom plate 42 and extends obliquely toward the front side, a horizontal portion 44b extending horizontally from the tip of the first inclined portion 44a, and a tip of the horizontal portion 44b. Although it is comprised with the 2nd inclination part 44c extended and inclined toward the downward direction, it is not limited to this. 3 and 4, reference symbol h <b> 2 leads to an opening h <b> 1 of the support plate 30 formed in the base cylinder 28 for passing the other end of the operating member 11 when the operating member 11 is assembled to the base member 5. It is a notch.

ハウジング部材7は、ペダル9の踏み込みによるディスペンサー付き容器3の上方への変位と協働して押圧ヘッド17を押し込んで容器本体13内の内容液を噴出させるものであり、図1に示すように、ディスペンサー付き容器3の周囲を取り囲み下端部がベース部材5の外周壁32に外側からねじ嵌合して保持される胴体部48と、該胴体部48の上端に連設されて中央に押圧ヘッド17を突出させる開口h3を形成する頂壁部50とからなる。該開口h3の縁部は、ディスペンサー付き容器3を上方に変位させた際に押圧ヘッド17の外筒17cに形成された段差mに当接する押込み部50aを構成する。なお、各部材3,5,7,11の製造上の寸法誤差を考慮して、ハウジング部材7の高さは、作動部材11を作動させない状態(初期状態)において押込み部50aと押圧ヘッド17の段差mとの間に所定の隙間Aが生じる高さとしておくことがよい。また、この例では、ハウジング部材7は、ねじによりベース部材5に固定すると説明したが、ハウジング部材7は、ベース部材5の外周壁32にアンダーカット嵌合により固定するようにしてもよい。さらに、ハウジング部材7の形状は、押圧ヘッド17を押し込むことができればとくに限定はなく、例えば、材料削減やデザイン性等の目的で胴体部48に一以上の開口部またはスリットを設けてもよい(図示省略)。また、ハウジング部材7は、透明または半透明の樹脂で形成することが好ましく、このようにすれば容器本体13内の内容物の残量を外部から容易に把握することが可能となる。   The housing member 7 cooperates with the upward displacement of the dispenser-equipped container 3 by depressing the pedal 9, and pushes the pressing head 17 to eject the content liquid in the container body 13, as shown in FIG. A body portion 48 surrounding the periphery of the container 3 with a dispenser and having a lower end portion screwed and held on the outer peripheral wall 32 of the base member 5 from the outside; 17 and a top wall portion 50 that forms an opening h3 from which 17 is projected. The edge portion of the opening h3 constitutes a pushing portion 50a that comes into contact with a step m formed on the outer cylinder 17c of the pressing head 17 when the container 3 with a dispenser is displaced upward. In consideration of manufacturing dimensional errors of the members 3, 5, 7, 11, the height of the housing member 7 is set so that the pressing portion 50 a and the pressing head 17 are in a state where the operating member 11 is not operated (initial state). It is preferable to set the height such that a predetermined gap A is formed between the step m. In this example, it has been described that the housing member 7 is fixed to the base member 5 with screws. However, the housing member 7 may be fixed to the outer peripheral wall 32 of the base member 5 by undercut fitting. Furthermore, the shape of the housing member 7 is not particularly limited as long as the pressing head 17 can be pushed in. For example, one or more openings or slits may be provided in the body portion 48 for the purpose of material reduction, design, and the like ( (Not shown). The housing member 7 is preferably formed of a transparent or translucent resin. In this way, the remaining amount of the contents in the container body 13 can be easily grasped from the outside.

作動部材11は、使用者によるペダル9の踏み込みによりディスペンサー付き容器3を上方に変位させ(押し上げ)、ハウジング部材7の押込み部50aに押圧ヘッド17を押し込ませて容器本体13内の内容液を噴出させるものであり、図5および図6に示すように、一端部に設けられた上記ペダル9と、該ペダル9から後方に延びるチャンネル形状(断面C字形状)の本体部52と、本体部52の側面にそれぞれ設けられ、ベース部材5の一対の軸受38にそれぞれ支持される一対の軸部54とを有してなる。また、作動部材11の本体部52の内側には、ベース部材5の底板42から延出するベンド板44の先端が当接するよう作動部材11の延在方向に直交する向きで配置され、該ベンド板44からの付勢力をもって弾性変形可能な当接板56が下方に向けて設けられている。さらに、ペダル9の上面には図示のように、滑り止め用の凸部9aを設けてもよい。   The actuating member 11 displaces (pushes up) the dispenser-equipped container 3 when the user depresses the pedal 9, and pushes the pressing head 17 into the pushing portion 50 a of the housing member 7 to eject the content liquid in the container body 13. As shown in FIGS. 5 and 6, the pedal 9 provided at one end, a channel-shaped main body 52 extending rearward from the pedal 9 (C-shaped cross section), and a main body 52 And a pair of shaft portions 54 respectively supported by the pair of bearings 38 of the base member 5. Further, an inner side of the main body portion 52 of the operating member 11 is arranged in a direction orthogonal to the extending direction of the operating member 11 so that the tip of the bend plate 44 extending from the bottom plate 42 of the base member 5 is in contact with the bend. A contact plate 56 that can be elastically deformed by an urging force from the plate 44 is provided downward. Further, as shown in the figure, a non-slip convex portion 9a may be provided on the upper surface of the pedal 9.

作動部材11の他端部(本体部52の後方側の端部)には、U字状のスリットs2によりベンド片58が一体に区画形成されており、該ベンド片58は、押圧ヘッド17にその押込み限度を超える押込み力が加わった際にそれ自体の弾性揺動によりその押込み力を解放するよう構成されている。具体的には、ベンド片58のばね定数は、押圧ヘッド17を元の位置に復帰させるばね部材(ポンプ機構に組み込まれた上記ばね部材)のばね定数よりも大きく設定されており、このため、ベンド片58は、押圧ヘッド17がそのストロークエンドに達するまでの間はポンプ機構のばね部材が優先的に変形するため弾性揺動せず、押圧ヘッド17がストロークエンドに達した後に弾性揺動して押圧ヘッド17に加わる過剰な押圧力を吸収、解放する。図中の符号58aは、ベンド片58の上面に設けられ容器本体13の底部13dに向けて突出する突起であり、該突起58aは容器本体13の底部13dと当接する部分が曲面をなす形状に形成されている。この例では、突起58aを2つ設けているが、このような突起58aは一つのみ設けてもよい。   A bend piece 58 is integrally formed with a U-shaped slit s2 at the other end of the actuating member 11 (the rear end of the main body 52). When a pushing force exceeding the pushing limit is applied, the pushing force is released by its own elastic swing. Specifically, the spring constant of the bend piece 58 is set larger than the spring constant of the spring member (the spring member incorporated in the pump mechanism) that returns the pressing head 17 to the original position. The bend piece 58 does not swing elastically until the pressing head 17 reaches the stroke end because the spring member of the pump mechanism is preferentially deformed, and elastically swings after the pressing head 17 reaches the stroke end. The excessive pressing force applied to the pressing head 17 is absorbed and released. Reference numeral 58a in the drawing is a protrusion provided on the upper surface of the bend piece 58 and protruding toward the bottom portion 13d of the container main body 13, and the protrusion 58a has a shape in which a portion contacting the bottom portion 13d of the container main body 13 forms a curved surface. Is formed. In this example, two protrusions 58a are provided, but only one such protrusion 58a may be provided.

なお、作動部材11が水平状態(図6(a),(b)に示す状態)からベース板26(ベース板26を設けない場合には載置面G)に当接するまで(図9に示す状態)の揺動変位量は、ハウジング部材7の押込み部50aと押圧ヘッド17の段差mとの間に形成されるようにした上記隙間Aと押圧ヘッド17のストローク(ポンプ機構21のピストンのストローク)との和である必要押上げ量よりも大きく設定しておくことが好ましく、これによれば、押圧ヘッド17がストロークエンド(押込み限度)に達した時点においても作動部材11に所定の踏み込み代(図8に示す隙間B)を残しておくことができる。   Note that the operation member 11 is in a horizontal state (the state shown in FIGS. 6A and 6B) until it comes into contact with the base plate 26 (the mounting surface G when the base plate 26 is not provided) (shown in FIG. 9). The swing displacement amount in the state) is the stroke of the gap A and the pressure head 17 (the stroke of the piston of the pump mechanism 21) formed between the pushing portion 50a of the housing member 7 and the step m of the pressure head 17. It is preferable to set it to be larger than the required push-up amount, which is the sum of the press member 17), and according to this, even when the press head 17 reaches the stroke end (push-in limit), the actuating member 11 has a predetermined depression amount. (The gap B shown in FIG. 8) can be left.

次いで、上記形態をとる足踏み式液体噴出装置1の作用について説明する。図7は、ディスペンサー付き容器3をベース部材5の保持部36内にセットする前の状態を示しており、この状態では、作動部材11は、ベース部材5の底板42に一体に形成されたベンド板44によって略水平姿勢に付勢されているため、移送中等に足踏み式液体噴出装置1が揺らされたり傾けられたりしても作動部材11が揺動して破損することはない。また、ディスペンサー付き容器3をベース部材5の保持部36内にセットする際にも、作動部材11はベンド板44に付勢されて略水平姿勢に維持されているため、作動部材11とくには作動部材11の他端部がディスペンサー付き容器3に干渉することがなく、ディスペンサー付き容器3のセットをスムーズに行うことができる。実際にディスペンサー付き容器3内の内容液を吐出するにあたっては、ディスペンサー付き容器3のオーバッキャップ24を外し、ディスペンサー付き容器3をベース部材5の保持部36内にセットし、ハウジング部材7をベース部材5に装着した状態から、使用者が、ベース部材5に揺動可能に支持された、足で踏むことのできるペダル9を踏み込むと、図8に示すように、作動部材11がベンド板44の付勢力に抗して揺動し、その作動部材11の揺動と連動してディスペンサー付き容器3が上方に押し上げられハウジング部材7の押込み部50aによって押圧ヘッド17が下方に押し込まれるので、容器本体13内の内容液が加圧、圧縮されて押圧ヘッド17の噴出口17aより例えば霧状の形態で噴出する。このようにして内容液の吐出が行われた後に使用者がペダル9の踏み込みを解放すると、押圧ヘッド17はポンプ機構21のばね部材の付勢力をもっても元の位置へ戻され、揺動姿勢にある作動部材11はベンド板44の付勢力をもって元の水平姿勢(図1の状態)に戻されるので、ポンプ機構21のばね部材の付勢力のみで作動部材11を水平姿勢に戻す場合に比べて短時間に作動部材11を水平姿勢に戻すことができ、引き続いて内容液の吐出の要求があった場合でもそれに迅速に対応することが可能である。   Next, the operation of the foot-operated liquid ejecting apparatus 1 that takes the above form will be described. FIG. 7 shows a state before the container 3 with a dispenser is set in the holding portion 36 of the base member 5. In this state, the actuating member 11 is a bend formed integrally with the bottom plate 42 of the base member 5. Since the plate 44 is biased to a substantially horizontal posture, the actuating member 11 will not swing and be damaged even if the foot-operated liquid ejection device 1 is shaken or tilted during transfer or the like. Further, when the container 3 with a dispenser is set in the holding portion 36 of the base member 5, the operating member 11 is biased by the bend plate 44 and is maintained in a substantially horizontal posture. The other end of the member 11 does not interfere with the container 3 with a dispenser, and the container 3 with a dispenser can be set smoothly. When actually discharging the liquid in the container 3 with a dispenser, the overcap 24 of the container 3 with a dispenser is removed, the container 3 with a dispenser is set in the holding portion 36 of the base member 5, and the housing member 7 is used as a base. When the user depresses the pedal 9 which can be stepped on with his / her foot supported by the base member 5 so as to be swingable from the state where it is mounted on the member 5, as shown in FIG. Since the container 3 with a dispenser is pushed upward in conjunction with the swing of the actuating member 11, the pressing head 17 is pushed downward by the pushing portion 50a of the housing member 7. The content liquid in the main body 13 is pressurized and compressed and ejected from the ejection port 17a of the pressing head 17 in, for example, a mist form. When the user releases the depression of the pedal 9 after the content liquid is discharged in this way, the pressing head 17 is returned to the original position even with the urging force of the spring member of the pump mechanism 21, and is brought into the swinging posture. Since one actuating member 11 is returned to the original horizontal posture (the state shown in FIG. 1) by the urging force of the bend plate 44, the actuating member 11 is returned to the horizontal posture only by the urging force of the spring member of the pump mechanism 21. The actuating member 11 can be returned to the horizontal posture in a short time, and it is possible to respond quickly even if there is a subsequent request for the discharge of the content liquid.

このように、本実施形態の足踏み式液体噴出装置1は、部品点数の増加を伴うことなく、移送中の作動部材の揺動に起因した破損を防止することができるとともに装置への容器のセットを容易に行うことができ、かつ引き続く内容液の吐出に対する要求にも迅速に対応することができる。   As described above, the foot-operated liquid ejection device 1 of the present embodiment can prevent breakage due to swinging of the operating member during transfer without increasing the number of parts, and can set a container in the device. Can be easily performed, and the request for the subsequent discharge of the content liquid can be quickly met.

また、本実施形態の足踏み式液体噴出装置1によれば、作動部材11にベース部材5のベンド板44からの付勢力を受けるとともにペダル踏み込み時に該付勢力をもって弾性変形する当接板56を設けたことから、ペダル9の踏み込み時にベンド板44および当接板56の双方をベンド変形させて、作動部材11の踏み込み感をより滑らかなものとすることができる。   Further, according to the foot-operated liquid ejecting apparatus 1 of the present embodiment, the operating member 11 is provided with the contact plate 56 that receives the biasing force from the bend plate 44 of the base member 5 and elastically deforms with the biasing force when the pedal is depressed. For this reason, when the pedal 9 is depressed, both the bend plate 44 and the contact plate 56 are bent, and the feeling of depression of the actuating member 11 can be made smoother.

さらに、本実施形態の足踏み式液体噴出装置1では、図8に示す、押圧ヘッド17がストロークエンドに達した時点では作動部材11には所定の踏み込み代(隙間B)が残っており、この状態から使用者がさらにペダル9を踏み込んで押圧ヘッド17にその押込み限度を超える押込み力が加わる場合には、図9に示すように作動部材11の他端部に設けられたベンド片58がそれ自体の弾性揺動によりその押込み力を解放するので、押圧ヘッド17に過剰な押圧力が加わることがなく、ディスペンサー15の破損を回避することができる。   Further, in the foot-operated liquid ejection device 1 of the present embodiment, when the pressing head 17 reaches the stroke end as shown in FIG. 8, a predetermined stepping margin (gap B) remains in the operating member 11, and this state When the user further depresses the pedal 9, and a pressing force exceeding the pressing limit is applied to the pressing head 17, the bend piece 58 provided at the other end of the operating member 11 itself is shown in FIG. Since the pushing force is released by the elastic swing of the pressure, excessive pressing force is not applied to the pressing head 17, and damage to the dispenser 15 can be avoided.

さらに、本実施形態の足踏み式液体噴出装置1によれば、押圧ヘッド17がその押込み限度に到達した時点においても作動部材11に踏み込み代(隙間B)が残るよう構成したことから、各部材3,5,7,11に製造上の寸法誤差が生じた場合でも確実に押圧ヘッド17をストロークエンドまで押し込むことができ、より安定した定量吐出を実現することができる。   Further, according to the foot-operated liquid ejecting apparatus 1 of the present embodiment, the stepping allowance (gap B) remains in the actuating member 11 even when the pressing head 17 reaches its pressing limit. 5, 5, 7, and 11, even if a manufacturing dimensional error occurs, the pressing head 17 can be surely pushed to the stroke end, and more stable quantitative discharge can be realized.

さらに、本実施形態の足踏み式液体噴出装置1によれば、ペダル9が踏み込まれていない初期状態において、ハウジング部材7の押込み部50aと、押圧ヘッド17の、押込み部50aが当たる部分(段差m)との間に所定の隙間Aが形成されるよう構成したことから、各部材3,5,7,11に製造上の寸法誤差が生じた場合でも該隙間Aの存在により寸法誤差を吸収して安定した定量吐出を実現することができる。   Furthermore, according to the foot-operated liquid ejection device 1 of the present embodiment, in the initial state where the pedal 9 is not depressed, the portion (step m) of the pushing portion 50a of the housing member 7 and the pushing portion 50a of the pressing head 17 hits. ), A predetermined gap A is formed between each of the members 3, 5, 7, and 11, so that the dimensional error is absorbed by the existence of the gap A even if a dimensional error in manufacturing occurs. And stable dispensing can be realized.

しかも、本実施形態の足踏み式液体噴出装置1によれば、作動部材11の他端部に形成されたベンド片58に、容器本体13の底部13dと当接する部分が曲面をなす突起58aを設けたことから、作動部材11によりディスペンサー付き容器3を押し上げる際に突起58aの曲面(外面)が容器本体13の底部13dの表面を円滑に摺動し、スムーズな踏み込み感を実現することができる。   Moreover, according to the foot-operated liquid ejecting apparatus 1 of the present embodiment, the bend piece 58 formed at the other end of the operating member 11 is provided with a protrusion 58a having a curved surface at a portion in contact with the bottom 13d of the container body 13. As a result, when the operation member 11 pushes up the container 3 with a dispenser, the curved surface (outer surface) of the protrusion 58a smoothly slides on the surface of the bottom 13d of the container body 13, and a smooth feeling of depression can be realized.

本発明により、足踏み式の液体噴出装置の吐出機構としてポンプ式のディスペンサーを用いたものにつき、部品点数の増加を伴うことなく、移送中の作動部材の揺動に起因した破損を防止することができるとともに装置への容器のセットを容易に行うことができ、かつ引き続く内容液の吐出に対する要求にも迅速に対応可能な足踏み式液体噴出装置を提供することが可能となった。   According to the present invention, a pump-type dispenser is used as a discharge mechanism of a stepping-type liquid ejecting apparatus, and damage due to the swinging of the operating member during transfer can be prevented without increasing the number of parts. In addition, it is possible to provide a stepping type liquid ejecting apparatus that can easily set a container in the apparatus and can quickly respond to a request for subsequent discharge of the content liquid.
