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。 TECHNICAL FIELD The present invention relates to a pump unit capable of discharging a liquid contained in a container to the outside by a user pressing two left and right levers.

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。 2. Description of the Related Art Techniques for discharging a liquid stored inside a container to the outside using a pump unit attached to a container body are well known in the art. A general pump unit suspends a cylinder into the container from a mounting cylinder fitted to the mouth and neck of the container, and pushes upward from within the cylinder to erect an operating member having a push-down head with a nozzle at the upper end. , by pushing down the push-down 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 press down the push head in the direction you want to discharge. It has been a problem that these operations are 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 order to solve the above problem, Japanese Patent Application Laid-Open Nos. 2001-158462 (Patent Document 1) and 2007-168864 (Patent Document 2) use the principle of leverage to enable ejection with a small force by gripping with multiple fingers. A liquid dispensing pump unit is disclosed that is capable and adjustable in dispensing position.

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 ejection onto the palm, it cannot be used for ejection to other than the palm, and the ejection portion and the operation portion protrude greatly in the lateral direction. There is a problem that it is difficult to make it compact. In addition, since the invention of Patent Document 2 discharges the liquid by pressing force from the left and right directions, it is necessary to provide a special shape that serves as a guide inclined surface on the container side, and there is a problem that it cannot be applied to various ready-made containers. .

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 the natural state of the pump unit according to the embodiment of the present application, and FIG. 2 is a cross-sectional view showing its internal structure. The pump unit 1 includes a cylinder 9 for sucking up the liquid content, a push-down head 10 connected to the cylinder 9, a discharge nozzle 12 formed on the push-down head 10, and the push-down head 10 in its internal space. and two left and right pressing levers 3 arranged outside the cylinder 2 and hinged at the upper part 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 are semi-cylindrical and integrally molded of resin, and are thinly hinged by a hinge connecting portion 7 fixed to the top (upper surface) of the cylindrical body 2, and form a V-shape in a natural state. open to The two left and right pressing levers 3 and the pressing head 10 are connected by two connecting arms 6, and one end of the connecting arm 6 constitutes the first movable portion 4 between the pressing lever 3 and the connecting arm. The other end of 6 constitutes a second movable portion 5 with a 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 vertical movement of the depressing head 10 has a conventionally well-known structure, and will not be described here. Further, since the push-down head 10 is always urged to extend upward, the push lever 3 connected to the push-down head 10 via the connecting arm 6 opens in the left and right in the natural state as described above. is energized 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. 6A, 6B, 7A, and 7B, the first movable portion 4 and the second movable portion 5 may be hinged using a movable shaft, and A thin hinge connection in which each part is integrally molded with resin may be used. Furthermore, the left and right pressing levers 3 are not limited to being integrally molded with resin, and may be molded separately and then hinged using a movable shaft. 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 using a well-known technique.

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), and FIG. 4 is a sectional view showing the internal structure at that time. When the two pressing levers 3 are closed along the cylindrical body 2 by the user's pressing force, the two pressing levers 3 assume a cylindrical shape. In the process of closing the pressing lever 3 , the connecting arm 6 pushes down the pressing head 10 via the second movable portion, whereby the liquid contained in the container is discharged from the discharge nozzle 12 . It's 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 the liquid storage container is formed at the lower portion of the cylindrical body 2, so that it can be mounted to various ready-made containers. The container mounting portion 8 has a large diameter projecting radially from the upper side of the cylindrical body 2. As shown in FIG. It is configured to form a cylinder of the same diameter as the cylinder presented by the two pressure levers 3 when closed.

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はスロークSを上下動することができる。このスローク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 dynamically explaining the principle of the lever used in the present invention, showing that the hinge connecting portion 7 is the fulcrum, the first movable portion 4 is the point of action, and the tip side of the pressing lever 3 is the force point. ing. The left half of FIG. 8 is a cross-sectional view of the state in which the pressing lever 3 is closed, and the right half is a cross-sectional view of the natural state in which the pressing lever 3 is open. 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 and second movable parts, and the angle θ between the pressing head and the pressing lever in its 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を必ずしもスロークSだけ下ける必要はなく、使用者が押圧レバー3を適宜の範囲で押圧することで、必要とする適宜料の内容物を吐出させることができる。 It should be noted that when the pressing operation of the pressing lever 3 is started, the downward movement of the pressing head 10 is also started in conjunction with this pressing operation, and the ejection of the contents from the ejection nozzle 12 is also started. is not necessarily required to be lowered by the stroke S, and the user can press the pressing lever 3 in an appropriate range to discharge the content of the desired amount.

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。 Long holes 13 and 14 are formed in the side surface of the cylindrical body 2 so that the connecting arm 6 and the discharge nozzle 12 can move up and down, respectively. It is

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 embodiments, the liquid discharge pump is described as being used for discharging the liquid contained in the container, but a spray type 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, due to the presence of the left and right pressing levers and the ejection nozzle, the ejection direction can be easily grasped. The pressing head can be pushed down by , and the pressing lever can be held from the left and right, so that a 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 appropriately adjusting the pressing width of the pressing lever, the user can easily adjust the discharge amount. Compared to general trigger pumps, etc., in which the operation part protrudes forward, the forward protrusion is small and compact. is possible. Moreover, since it is not necessary to provide a special structure on the container side, it can be applied to various ready-made containers.
