Description

本発明は、使用者が左右２つのレバーを押圧することにより、容器内に収納されている液体内容物を外部に吐出可能なポンプユニットに関する。 The present invention relates to a pump unit capable of discharging liquid contents stored in a container to the outside by a user pressing two levers on the left and right.

容器内部に収納されている液体物を、容器本体に装着したポンプユニットを用いて外部に吐出する技術は、従来からよく知られている。一般的なポンプユニットは、容器口頸部に嵌合させた装着筒からシリンダを容器内へ垂下すると共に、シリンダ内から上方付勢してノズル付き押下ヘッドを上端部に有する作動部材を起立させ、押下ヘッドを押し下げることで、容器内に収納されている液体を吸上げ、ノズルから吐出させている。 A technique for discharging a liquid material stored inside a container to the outside using a pump unit mounted on the container body has been well known. In a general pump unit, a cylinder is hung into the container from a mounting cylinder fitted to the neck of the container, and an operating member having a pressing head with a nozzle at the upper end is erected by urging upward from the inside of the cylinder. By pushing down the pressing head, the liquid stored in the container is sucked up and discharged from the nozzle.

こうした従来のポンプユニットを用いて、容器内の液体を外部に吐出させる際には、ノズルの方向を確認して吐出したい方向へ向けて押下ヘッドを押し下げる必要があるが、視力の弱い者や指の力が弱い者などにはこれらの操作が難しいことが問題となっていた。 When using such a conventional pump unit to discharge the liquid in the container to the outside, it is necessary to check the direction of the nozzle and push down the pressing head in the direction to be discharged. It was a problem that these operations were difficult for people with weak power.

上記問題に対し特開２００１−１５８４６２号公報（特許文献１）及び特開２００７−１６８８６４号公報（特許文献２）には、テコの原理を用いて複数の指で握る動作により小さな力で吐出が可能であるとともに吐出位置を調整できる液体吐出ポンプユニットが開示されている。 In response to the above problems, Japanese Patent Application Laid-Open No. 2001-158462 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2007-168864 (Patent Document 2) use the principle of leverage to discharge with a small force by grasping with a plurality of fingers. A liquid discharge pump unit that is capable and can adjust the discharge position is disclosed.

しかしながら、特許文献１に記載の発明は手のひらへの吐出に特化したものであるため、手のひら以外に吐出する場合には使用できず、かつ吐出部と操作部が大きく横方向に張り出してしまうためコンパクト化が難しいという課題がある。また特許文献２の発明は左右方向からの押圧力で液体を吐出しているため、容器側に案内傾斜面となる特殊な形状を設ける必要があり、様々な既製容器に適用できないという課題がある。 However, since the invention described in Patent Document 1 is specialized for discharging to the palm, it cannot be used when discharging to other than the palm, and the discharging portion and the operating portion greatly protrude in the lateral direction. There is a problem that it is difficult to make it compact. Further, since the invention of Patent Document 2 discharges a liquid by pressing force from the left-right direction, it is necessary to provide a special shape as a guide inclined surface on the container side, and there is a problem that it cannot be applied to various ready-made containers. ..

本願発明は、上記した従来技術が有する課題を解決し、吐出方向が分かりやすく、小さな力で操作でき、また吐出対象となる場所を限定することなく、コンパクトで、かつ多様な既製容器にそのまま使用可能な縦型ポンプユニットを提供することを目的とする。 The present invention solves the above-mentioned problems of the prior art, allows the discharge direction to be easily understood, can be operated with a small force, and can be used as it is in a compact and various ready-made containers without limiting the place to be discharged. It is an object of the present invention to provide a possible vertical pump unit.

前記縦型ポンプユニットは、
液体内容物を吸い上げるシリンダと、前記シリンダに連結される押下ヘッドと、前記押下ヘッドの上部に形成される吐出ノズルと、前記押下ヘッドをその内部空間に収容する筒体と、前記筒体の外側に配置され、かつ前記筒体の上部においてヒンジ連結された左右２つの押圧レバーと、を含み、
２つの前記押圧レバーと前記押下ヘッドは、２つの連結アームによってそれぞれ連結され、
前記連結アームの一端は前記押圧レバーとの間で第１可動部を構成し、
前記連結アームの他端は前記押下ヘッドとの間で第２可動部を構成し、
前記押圧レバーは半円筒形状であり、２つの前記押圧レバーは自然状態において側面視でハ字状に開いており、使用者による押圧力によって閉じた状態で前記筒体を取り囲む円筒形状を呈する、
ことを特徴とする。 In order to achieve the above object, the present invention is a vertical pump unit that is mounted on a liquid storage container and discharges the liquid contents to the outside of the container.
The vertical pump unit is
A cylinder that sucks up the liquid contents, a push head connected to the cylinder, a discharge nozzle formed on the upper portion of the push head, a cylinder that accommodates the push head in its internal space, and the outside of the cylinder. Includes two left and right pressing levers, which are arranged in the cylinder and hinged at the top of the cylinder.
The two pressing levers and the pressing head are connected by two connecting arms, respectively.
One end of the connecting arm constitutes a first movable portion with the pressing lever.
The other end of the connecting arm constitutes a second movable portion with the pressing head.
The pressing lever has a semi-cylindrical shape, and the two pressing levers open in a V shape in a side view in a natural state, and exhibit a cylindrical shape surrounding the cylinder in a closed state due to a pressing force by a user.

上記構成を有する本願発明によれば、左右の押圧レバーを手で掴むようにして握ることで、その力が連結アームを介して押下ヘッドを押し下げる下方向の力に変換され、吐出ノズルから容器内の内容物を吐出することが出来る。即ち、テコの原理を応用することで小さな力で内容物を吐出できるとともに、押下げヘッドから吐出ノズルを突出させることで、ピンポイント吐出を容易に行うことができる。 According to the present invention having the above configuration, by grasping the left and right pressing levers by hand, the force is converted into a downward force that pushes down the pressing head via the connecting arm, and the contents inside the container from the discharge nozzle. It is possible to discharge an object. That is, by applying the principle of leverage, the contents can be ejected with a small force, and by projecting the ejection nozzle from the push-down head, pinpoint ejection can be easily performed.

以下、本願発明の実施形態について詳細に説明する。
図１は、本願実施形態に係るポンプユニットの自然状態を示す斜視図であり、図２は、その内部構造を示す断面図である。ポンプユニット１は、液体内容物を吸い上げるためのシリンダ９と、当該シリンダ９に連結される押下ヘッド１０と、当該押下ヘッド１０の上部に形成される吐出ノズル１２と、押下ヘッド１０をその内部空間に収容する筒体２と、当該筒体２の外側に配置され、かつ筒体２の上部においてヒンジ連結された左右２つの押圧レバー３を有している。 Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a perspective view showing a natural state of the pump unit according to the embodiment of the present application, and FIG. 2 is a cross-sectional view showing the internal structure thereof. The pump unit 1 has a cylinder 9 for sucking up liquid contents, a pressing head 10 connected to the cylinder 9, a discharge nozzle 12 formed on the upper portion of the pressing head 10, and an internal space of the pressing head 10. It has a cylinder 2 housed in the cylinder 2 and two left and right pressing levers 3 arranged outside the cylinder 2 and hinged to each other on the upper portion of the cylinder 2.

左右２つの押圧レバー３は、半円筒形状であって樹脂によって一体成形され、筒体２の上部（上面）に固定されたヒンジ連結部７によって薄肉ヒンジ連結されており、自然状態においてハ字状に開いている。また、左右２つの押圧レバー３と押下ヘッド１０は、２つの連結アーム６によってそれぞれ連結されており、連結アーム６の一端は押圧レバー３との間で第１可動部４を構成し、連結アーム６の他端は押下ヘッド１０との間で第２可動部５を構成している。 The two left and right pressing levers 3 have a semi-cylindrical shape and are integrally molded with resin, and are thin-walled hinged by a hinge connecting portion 7 fixed to the upper part (upper surface) of the tubular body 2. Open to. Further, the two left and right pressing levers 3 and the pressing head 10 are respectively connected by two connecting arms 6, and one end of the connecting arm 6 constitutes a first movable portion 4 with the pressing lever 3, and the connecting arm is formed. The other end of 6 constitutes a second movable portion 5 with the pressing head 10.

押下ヘッド１０の上下動によるポンプは従来周知の構造であり、ここでは特に説明しない。また押下ヘッド１０は常に上方側に延びるよう付勢されているため、連結アーム６を介して押下ヘッド１０に連結されている押圧レバー３は、上記のとおり自然状態において左右にハ字状に開くように付勢される。 The pump by the vertical movement of the pressing head 10 has a conventionally well-known structure, and is not particularly described here. Further, since the pressing head 10 is always urged to extend upward, the pressing lever 3 connected to the pressing head 10 via the connecting arm 6 opens in a C shape to the left and right in the natural state as described above. Be urged to.

図６（ａ）（ｂ）、図７（ａ）（ｂ）にそれぞれ示すように、第１可動部４及び第２可動部５は、可動軸を用いたヒンジ連結であってもよく、また各パーツを樹脂で一体成形した薄肉ヒンジ連結であってもよい。さらに、左右２つの押圧レバー３は、樹脂によって一体成形したものに限らず、それぞれ別体に成形した後に、可動軸を用いてヒンジ連結してもよい。いずれにしても第１可動部４及び第２可動部５は、周知の手法を用いて、押圧レバー３、押圧ヘッド１０、連結アーム６を可動自在に接続する。 As shown in FIGS. 6 (a) and 6 (b) and 7 (a) and 7 (b), the first movable portion 4 and the second movable portion 5 may be hinged using a movable shaft, and may be connected to each other. A thin-walled hinge connection in which each part is integrally molded with resin may be used. Further, the two left and right pressing levers 3 are not limited to those integrally molded with resin, and may be hinge-connected using a movable shaft after being molded separately. In any case, the first movable portion 4 and the second movable portion 5 movably connect the pressing lever 3, the pressing head 10, and the connecting arm 6 by using a well-known method.

図３は、ポンプユニット１の押圧レバー３を閉じた状態（内容物を最大限に吐出した状態）を示す斜視図であり、図４は、その時の内部構造を示す断面図である。使用者による押圧力によって２つの押圧レバー３が筒体２に沿うように閉じられると、２つの押圧レバー３は円筒形状を呈する。この押圧レバー３が閉じる動作の過程で、連結アーム６が、第２可動部を介して押下ヘッド１０を下方側に押下げることにより、容器内に収容されている液体が吐出ノズル１２から吐出するようになっている。 FIG. 3 is a perspective view showing a state in which the pressing lever 3 of the pump unit 1 is closed (a state in which the contents are discharged to the maximum extent), and FIG. 4 is a cross-sectional view showing the internal structure at that time. When the two pressing levers 3 are closed along the tubular body 2 by the pressing force of the user, the two pressing levers 3 have a cylindrical shape. In the process of closing the pressing lever 3, the connecting arm 6 pushes the pressing head 10 downward via the second movable portion, so that the liquid contained in the container is discharged from the discharge nozzle 12. It has become like.

筒体２の下方部には、液体収納容器に装着するためのネジ式の容器装着部８が形成されており、これによって各種の既製容器にも装着可能となっている。この容器装着部８は、筒体２の上方側より径方向に突出する大径となっており、図３に示すとおり、２つの押圧レバー３が筒体２の上方側の小径部に沿って閉じた際に、２つの押圧レバー３によって呈される円筒と同径の円筒となるように構成されている。 A screw-type container mounting portion 8 for mounting on the liquid storage container is formed in the lower portion of the tubular body 2, whereby it can be mounted on various ready-made containers. The container mounting portion 8 has a large diameter that protrudes in the radial direction from the upper side of the cylinder 2, and as shown in FIG. 3, two pressing levers 3 are along the smaller diameter portion on the upper side of the cylinder 2. When closed, it is configured to be a cylinder having the same diameter as the cylinder presented by the two pressing levers 3.

図８は、本発明で利用するテコの原理を力学的に説明する図であり、ヒンジ連結部７が支点、第１可動部４が作用点、押圧レバー３の先端側が力点となることを示している。図８の左半分は押圧レバー３が閉じた状態の断面図、右半分は押圧レバー３が開いた自然状態の断面図であり、図示するように押圧レバー３の押圧動作によって、押下ヘッド１０はストロークＳを上下動することができる。このストロークＳは、押圧レバー３の長さＬ、第１可動部及び第２可動部の設置位置、押下ヘッドと自然状態の押圧レバーとのなす角度θによって適宜に調整することができる。 FIG. 8 is a diagram for mechanically explaining the principle of leverage used in the present invention, showing that the hinge connecting portion 7 is a fulcrum, the first movable portion 4 is an action point, and the tip end side of the pressing lever 3 is a force point. ing. The left half of FIG. 8 is a cross-sectional view in a state where the pressing lever 3 is closed, and the right half is a cross-sectional view in a natural state in which the pressing lever 3 is opened. The stroke S can be moved up and down. This stroke S can be appropriately adjusted by the length L of the pressing lever 3, the installation positions of the first movable portion and the second movable portion, and the angle θ formed by the pressing head and the pressing lever in the natural state.

なお、押圧レバー３の押圧動作が開始されると、この押圧動作に連動して押下ヘッド１０の下方移動も始まり、これによって内容物の吐出ノズル１２からの吐出も開始されるため、押下ヘッド１０を必ずしもストロークＳだけ下げる必要はなく、使用者が押圧レバー３を適宜の範囲で押圧することで、必要とする適宜量の内容物を吐出させることができる。 When the pressing operation of the pressing lever 3 is started, the pressing head 10 also starts to move downward in conjunction with this pressing operation, and thereby the ejection of the contents from the ejection nozzle 12 is also started. Therefore, the pressing head 10 is started. It is not always necessary to lower the stroke S by the stroke S, and when the user presses the pressing lever 3 in an appropriate range, a required appropriate amount of contents can be discharged.

また、筒体２の側面には、連結アーム６及び吐出ノズル１２が上下動できる長孔１３、１４がそれぞれ形成され、さらに押圧レバー３にも、吐出ノズル１２が上下動できる長孔１５が形成されている。 Further, on the side surface of the tubular body 2, elongated holes 13 and 14 that allow the connecting arm 6 and the discharge nozzle 12 to move up and down are formed, respectively, and further, the pressing lever 3 also has an elongated hole 15 that allows the discharge nozzle 12 to move up and down. Has been done.

また、上記実施例では容器内に収容されている液体の吐出ポンプとして説明したが、スプレー式ポンプや泡ポンプであっても良い。 Further, in the above embodiment, the liquid discharge pump contained in the container has been described, but a spray pump or a foam pump may be used.

以上のとおり本願発明によれば、左右の押圧レバーと吐出ノズルの存在により、吐出方向が容易に把握できるとともに、左右の押圧レバーの下半分を掴んで横方向に押すとテコの原理により軽い力で押下げヘッドを押し下げることができ、左右から押圧レバーをホールドできるため安定した吐出操作を行うことができる。 As described above, according to the present invention, the discharge direction can be easily grasped by the presence of the left and right pressing levers and the discharge nozzle, and when the lower halves of the left and right pressing levers are grasped and pushed laterally, a light force is applied by the principle of the lever. The push-down head can be pushed down with, and the pressing lever can be held from the left and right, so stable discharge operation can be performed.

また押圧レバーの押し幅を適宜に調節することで、使用者は吐出量を容易に調整でき、操作部が前方に張り出している一般的なトリガーポンプ等に比べて、前方への張り出しが小さくコンパクト化が可能である。また容器側に特殊な構造を設ける必要がないため様々な既製容器に適用することが出来る。 In addition, by adjusting the push width of the pressing lever appropriately, the user can easily adjust the discharge amount, and the forward protrusion is smaller and more compact than a general trigger pump with the operation unit protruding forward. Can be converted. Moreover, since it is not necessary to provide a special structure on the container side, it can be applied to various ready-made containers.
