Description

本発明は、計量ポンプ容器、例えば洗口液などの薬剤、飲み物、香水などの各種液体を収納しかつ計量するのに適した計量ポンプ容器に関する。 The present invention relates to a measuring pump container, for example, a measuring pump container suitable for storing and measuring various liquids such as a drug such as mouthwash, a drink, and a perfume.

この種の計量ポンプ容器として、圧搾可能な胴部から口頸部を起立した容器体と、前記口頸部に付設したヘッド部とからなり、このヘッド部は、有底筒状の広口の計量筒とこの計量筒の上面を閉塞する蓋体とからなり、前記計量筒の底壁の外周部から、前記口頸部の外面に螺合させたネジ筒を、前記底壁の中央部から容器体の底部側へ延びる送出パイプを、それぞれ垂下しており、前記胴部の圧搾により、容器体内の液体を送出パイプの圧搾により、計量筒内に送出するように構成したものが知られている（特許文献１）。 This type of measuring pump container consists of a container body in which the mouth and neck are erected from a squeezable body and a head part attached to the mouth and neck, and this head part is a bottomed tubular wide-mouthed measuring container. It consists of a cylinder and a lid that closes the upper surface of the measuring cylinder, and a screw cylinder screwed from the outer peripheral portion of the bottom wall of the measuring cylinder to the outer surface of the mouth and neck is placed in a container from the central portion of the bottom wall. It is known that each delivery pipe extending to the bottom side of the body is hung down, and the liquid in the container is sent out into the measuring cylinder by squeezing the delivery pipe by squeezing the body. (Patent Document 1).

特開２０１８−３４８５７JP-A-2018-34857

特許文献１の計量ポンプ容器は、一定の程度の圧搾操作を前記胴部に加えることにより、一定量の液体を容器体から計量筒内へ送出するものである。
しかしながら、これでは胴部を圧搾する手に込める力の加減により、送出する液体の量に増減を生じてしまい、正確な計量ができない。
そこで、この容器で計量するときには、予め蓋体を開放し、計量筒内の液位が、この計量筒内に設定された目印に達するまで胴部の圧搾を続けるという手順をとる必要がある。
従って、蓋体を開放する手間、そして、計量筒内の液位を目視する手間が余分に必要であり、面倒である。
特に洗口液などのように一度に使用する液量が一度の吐出操作で得られる液体の量より多いときには、圧搾を繰り返す必要であることがある。その場合には、計量筒内の液位を目視する手間がより多く生じ、使い勝手がよくない。
また計量操作の間に蓋体を開放しているため、誤って容器を傾けたときに、計量中の液体が周囲に溢れてしまう可能性がある。 The measuring pump container of Patent Document 1 delivers a certain amount of liquid from the container body into the measuring cylinder by applying a certain degree of squeezing operation to the body portion.
However, in this case, the amount of liquid to be delivered increases or decreases depending on the amount of force that can be put into the hand that squeezes the body, and accurate measurement cannot be performed.
Therefore, when measuring with this container, it is necessary to open the lid in advance and continue squeezing the body until the liquid level in the measuring cylinder reaches the mark set in the measuring cylinder.
Therefore, it is troublesome to open the lid and to visually check the liquid level in the measuring cylinder.
It may be necessary to repeat squeezing, especially when the amount of liquid used at one time, such as mouthwash, is greater than the amount of liquid obtained in a single discharge operation. In that case, it takes more time and effort to visually check the liquid level in the measuring cylinder, which is not convenient.
In addition, since the lid is opened during the weighing operation, if the container is accidentally tilted, the liquid being weighed may overflow to the surroundings.

本発明の第１の目的は、使い勝手が良い計量ポンプ容器、特にポンピングを繰り返す場合に使い勝手がよい計量ポンプ容器を提供することである。
本発明の第２の目的は、蓋体を閉じたままで簡単に計量することができる計量ポンプ容器を提供することである。 A first object of the present invention is to provide a measuring pump container that is easy to use, particularly a measuring pump container that is easy to use when pumping is repeated.
A second object of the present invention is to provide a measuring pump container that can be easily measured with the lid closed.

第１の手段は、口頸部６を起立する容器体２と、
前記口頸部６の外面に嵌合された装着キャップ１０と、
前記口頸部６に取り付けられた吐出ポンプ２０と、を具備し、
この吐出ポンプ２０は、前記装着キャップ１０の下面側から前記容器体２内へ垂設したシリンダ２４を含むポンプ本体２２と、
前記シリンダ２４内から上方付勢状態で昇降可能に起立したステム３６を有し、このステム３６の上端に、押下げ用のヘッド部４２を付設した作動部材３２と、
を備え、
前記ヘッド部４２は、前記ステム３６と連設させた底壁４６の周端から筒周壁４８を起立させた計量筒４４を有し、かつ、この計量筒４４の上面を覆う蓋体５０で密閉させてなり、前記計量筒４４の内部に、ステム３６と連通する計量室Ｍを形成した。 The first means is to use a container body 2 that stands up the mouth and neck 6 and
A mounting cap 10 fitted to the outer surface of the mouth neck 6 and
A discharge pump 20 attached to the mouth and neck 6 is provided.
The discharge pump 20 includes a pump main body 22 including a cylinder 24 vertically installed in the container body 2 from the lower surface side of the mounting cap 10.
An operating member 32 having a stem 36 that stands up from the inside of the cylinder 24 so as to be able to move up and down in an upwardly biased state, and a head portion 42 for pushing down is attached to the upper end of the stem 36.
With
The head portion 42 has a measuring cylinder 44 in which a cylinder peripheral wall 48 is erected from the peripheral end of a bottom wall 46 connected to the stem 36, and is sealed with a lid 50 covering the upper surface of the measuring cylinder 44. A measuring chamber M communicating with the stem 36 was formed inside the measuring cylinder 44.

本手段では、図１に示すように、吐出ポンプ２０は、シリンダ２４内から上方付勢状態で昇降可能に起立したステム３６を有し、このステム３６の上端に、押下げ用のヘッド部４２を付設しており、かつこのヘッド部４２は、前記ステム３６と連設（連結を含む）させた底壁４６の周端から筒周壁４８を起立させた計量筒４４を有する。
そして、前記計量筒４４の内部に、ステム３６と連通する計量室Ｍを形成している。
この構造によれば、前記ヘッド部４２を所要回数だけ押し下げる操作を行うことにより、前記スクイズ式の計量吐出器の胴部の圧搾操作で計量する場合と比較して、正確な計量が可能となる。
また前記計量筒４４は、その計量筒４４の上面を覆う蓋体５０で密閉されている。
こうすることにより、利用者が前記ヘッド部４２を、所要回数以上に押すと、密閉空間である計量筒４４の内部が過度に高圧化して、ヘッド部４２の押し込みが困難となり、利用者がうっかりとして不必要な押し込み操作をすることを回避できる。 In this means, as shown in FIG. 1, the discharge pump 20 has a stem 36 that rises and falls from the inside of the cylinder 24 in an upwardly urged state, and a head portion 42 for pushing down is provided at the upper end of the stem 36. The head portion 42 has a measuring cylinder 44 in which the cylinder peripheral wall 48 is erected from the peripheral end of the bottom wall 46 connected (including connection) with the stem 36.
Then, a measuring chamber M communicating with the stem 36 is formed inside the measuring cylinder 44.
According to this structure, by performing the operation of pushing down the head portion 42 a required number of times, accurate weighing becomes possible as compared with the case of weighing by the squeezing operation of the body portion of the squeeze type measuring discharger. ..
Further, the measuring cylinder 44 is sealed with a lid 50 that covers the upper surface of the measuring cylinder 44.
By doing so, when the user pushes the head portion 42 more than the required number of times, the inside of the measuring cylinder 44, which is a closed space, becomes excessively high pressure, making it difficult to push the head portion 42, and the user inadvertently pushes the head portion 42. It is possible to avoid unnecessary pushing operation.

また前記筒周壁４８の上部内面には、フランジ孔ｆを有する内向きフランジ状頂壁４８ｄが付設されている。
そして、そのフランジ孔ｆを後述の蓋体５０のボス部５２で閉鎖することにより、筒周壁４８と底壁４６と内向きフランジ状頂壁４８ｄとで囲まれる計量室Ｍが密閉空間となるように形成している。
本実施形態の底壁４６は、筒周壁４８とは別個の部材（底壁部材）に形成しているが、両者を一体に形成しても構わない。
また図示例の計量筒４４は、縦長の形状としているが、その形状は適宜変更することができる。 As shown in FIG. 2, the measuring cylinder 44 has a straight tubular peripheral wall 48 and a bottom wall 46 that closes the lower surface of the tubular peripheral wall.
Further, an inward flange-shaped top wall 48d having a flange hole f is attached to the upper inner surface of the cylinder peripheral wall 48.

前記底壁４６は、図２に示す如く、前記筒周壁４８の下端部への取付け用の取付筒部４６ｂ、及び、前記ステム３６の上端部との連結用の連結筒部４６ｆを有する。
図示例では、前記底壁４６は、環状下段部４６ａの内周から起立筒部４６ｃを介して環状上段部４６ｅを内方突出した構造を有する。
そして、前記環状下段部４６ａの外周部から前記取付筒部４６ｂを起立するとともに、前記環状上段部４６ｅの内周部から前記連結筒部４６ｆを垂下させている。
また前記起立筒部４６ｃの内面には、前記雌ネジ部４６ｄが形成されている。こうした構成とすることにより、無駄なスペースを生ずることなく、前記雌ネジ部４６ｄを前記底壁４６に形成することができ、コンパクトな構造とすることができる。
もっともこれらの構造は適宜変更することができる。
また図示例では、前記環状下段部４６ａの下面と、前記リング状頂壁２８ａの上面とは相互に平坦な水平面であり、相互に向かい合うように形成されている。
前記リング状頂壁２８ａの上面と前記環状下段部４６ａの下面とは、前記雌ネジ部４６ｄに前記雄ネジ筒２８ｅを螺合させたときに、相互に当接するように形成している。
また前記の上部内面には、縦リブ４６ｇが付設されている。この縦リブ４６ｇの下端面には、前記ステム３６及び通気孔開閉筒４０の各上端が突き当てられている。 As shown in FIG. 2, the bottom wall 46 has a mounting cylinder portion 46b for attaching to the lower end portion of the cylinder peripheral wall 48, and a connecting cylinder portion 46f for connecting to the upper end portion of the stem 36.
In the illustrated example, the bottom wall 46 has a structure in which the annular upper stage portion 46e protrudes inward from the inner circumference of the annular lower stage portion 46a via the upright tubular portion 46c.
Then, the mounting cylinder portion 46b is erected from the outer peripheral portion of the annular lower stage portion 46a, and the connecting cylinder portion 46f is hung from the inner peripheral portion of the annular upper stage portion 46e.
Further, the female screw portion 46d is formed on the inner surface of the standing cylinder portion 46c. With such a configuration, the female screw portion 46d can be formed on the bottom wall 46 without creating wasted space, and a compact structure can be obtained.
However, these structures can be changed as appropriate.
Further, in the illustrated example, the lower surface of the annular lower portion 46a and the upper surface of the ring-shaped top wall 28a are horizontal planes that are flat to each other and are formed so as to face each other.
The upper surface of the ring-shaped top wall 28a and the lower surface of the annular lower stage portion 46a are formed so as to come into contact with each other when the male screw cylinder 28e is screwed into the female screw portion 46d.
Further, a vertical rib 46 g is attached to the upper inner surface. The upper ends of the stem 36 and the vent opening / closing cylinder 40 are abutted against the lower end surface of the vertical rib 46 g.

前記筒周壁４８は、図２に示す如く、前記環状下段部４６ａから、少なくとも前記起立筒部４６ｃよりも高く上方へ延びている。
図示例では、前記筒周壁４８の下端部内面に切欠き４８ａを周設して、この切欠き４８ａを前記環状下段部４６ａの外周部に液密にかみ合わせている。
また前記切欠き４８ａの上側で前記筒周壁４８の下部内面に前記取付筒部４６ｂを密嵌させている。
もっともこれらの構造は適宜変更することができる。
また筒周壁４８の上端部は、後述の蓋周壁５０ｂとかみ合う係止爪４８ｂに形成されている。
本実施形態では、前記筒周壁４８及び蓋体５０の各後部をヒンジ４８ｃで連結している。
なお、本明細書では、説明の便宜上、図１の右側を“後”と、左側を“前”と、これらに直交する方向を“左右”というものとする。
図示例のヒンジは、筒周壁４８及び後述の蓋周壁５０ｂと一体に連続する薄肉ヒンジに形成されているが、この構造は適宜変更することができる。
図示例では、筒周壁４８の上端面は、後端側から前方へ下がる傾斜面に形成している。
こうすることにより、前記蓋周壁５０ｂの外面上端部に対する後述の蓋周壁５０ｂの着脱を容易にするためである。
前記筒周壁４８の上部内面からは内向きフランジ状頂壁４８ｄを介して口筒部４８ｅが起立されている。この口筒部は、内容物を外部のコップなどに注ぐための注出口、内容物が飲料である場合には、飲み口として用いることができる。
この口筒部４８ｅには、図４に示す如く、その筒壁の後側を、前側から後下方へ切断した切割りnが形成されている。
また図示例では、前記筒周壁４８の前面に、後述の指掛け部５０ｃの下側に位置させて凹み４８ｆを形成している。
さらに好適な図示例では、前記補助筒４９より上側に位置させて、前記筒周壁４８の外周面に回転操作時の指当て用のローレットを形成してもよい。 As shown in FIG. 2, the tubular peripheral wall 48 extends upward from the annular lower stage portion 46a at least higher than the standing tubular portion 46c.
In the illustrated example, a notch 48a is provided around the inner surface of the lower end portion of the tubular peripheral wall 48, and the notch 48a is liquid-tightly meshed with the outer peripheral portion of the annular lower stage portion 46a.
Further, the mounting cylinder portion 46b is tightly fitted to the lower inner surface of the cylinder peripheral wall 48 on the upper side of the notch 48a.
However, these structures can be changed as appropriate.
Further, the upper end portion of the cylinder peripheral wall 48 is formed on a locking claw 48b that meshes with the lid peripheral wall 50b described later.
In the present embodiment, the rear portions of the tubular peripheral wall 48 and the lid 50 are connected by a hinge 48c.
In this specification, for convenience of explanation, the right side of FIG. 1 is referred to as “rear”, the left side is referred to as “front”, and the direction orthogonal to these is referred to as “left and right”.
The hinge of the illustrated example is formed as a thin-walled hinge integrally continuous with the cylinder peripheral wall 48 and the lid peripheral wall 50b described later, but this structure can be appropriately changed.
In the illustrated example, the upper end surface of the cylinder peripheral wall 48 is formed as an inclined surface that descends forward from the rear end side.
By doing so, it is easy to attach / detach the lid peripheral wall 50b, which will be described later, to the upper end of the outer surface of the lid peripheral wall 50b.
From the upper inner surface of the cylinder peripheral wall 48, the mouth cylinder portion 48e stands up via the inward flange-shaped top wall 48d. This mouthpiece can be used as a spout for pouring the contents into an external cup or the like, and as a drinking spout when the contents are beverages.
As shown in FIG. 4, the mouth cylinder portion 48e is formed with a cut n in which the rear side of the cylinder wall is cut from the front side to the rear lower side.
Further, in the illustrated example, a recess 48f is formed on the front surface of the cylinder peripheral wall 48 so as to be located below the finger hook portion 50c described later.
In a more preferred illustrated example, a knurl for finger contact during a rotation operation may be formed on the outer peripheral surface of the cylinder peripheral wall 48 by being positioned above the auxiliary cylinder 49.

前記補助筒４９は、計量筒の外周面上部に付設されたフランジ状突部ｂを介して垂下されている。
この補助筒４９は、前記案内筒部１８に近接又は当接され、ヘッド部４２の昇降を案内させるように形成されている。もっとも、補助筒及びフランジ状突部を省略して、前記計量筒４４を、案内筒部１８に近接又は当接させた構造としても構わない。
なお、前記補助筒４９の上端側には、開蓋状態の蓋体を係止させるための係止凸部ｐが形成されている。なお、係止凸部の位置は適宜変更することができる。 The auxiliary cylinder 49 hangs down via a flange-shaped protrusion b attached to the upper part of the outer peripheral surface of the measuring cylinder.
The auxiliary cylinder 49 is formed so as to be brought close to or in contact with the guide cylinder portion 18 to guide the ascending / descending of the head portion 42. However, the auxiliary cylinder and the flange-shaped protrusion may be omitted, and the measuring cylinder 44 may be brought close to or in contact with the guide cylinder portion 18.
A locking convex portion p for locking the lid in the opened state is formed on the upper end side of the auxiliary cylinder 49. The position of the locking convex portion can be changed as appropriate.

前記蓋体５０は、図２に示す如く、天板５０ａの周端から蓋周壁５０ｂを垂設している。
そして蓋周壁５０ｂの後端を前記ヒンジ４８ｃで前記筒周壁４８に連結させている。
もっとも、こうしたヒンジキャップの構成に代えて、前記蓋周壁５０ｂを筒周壁４８に螺着させたネジキャップの構成としてもよい。
前記蓋周壁５０ｂの下端部内面は、筒周壁４８の上端に着脱可能に嵌着されている。好適な図示例では、前記係止爪４８ｂとかみ合う凹部を形成しており、これにより、前記計量室Ｍ内の高圧化に抵抗して、閉蓋状態を維持できるようにしている。なお、図示例と反対に、蓋周壁側に凹凸状の係合手段の凸部を、筒周壁側に凹部を形成してもよい。
前記蓋周壁５０ｂの前部には、指掛け部５０ｃが付設されている。
前記天板５０ａの上面後部側には、前記蓋体５０の開蓋時に前記係止凸部ｐとかみ合う係合凹部ｒを形成してもよい。これにより、前記蓋体５０の開蓋状態が維持される。なお、図示例と異なり、蓋体側に係止凸部を、補助筒側に係合凹部を形成してもよい。
前記天板５０ａの下面からは、柱状のボス部５２が垂設されている。
このボス部５２は、前記口筒部４８ｅの内面に密嵌されている。こうすることにより、前記内向きフランジ状頂壁４８ｄのフランジ孔ｆをより確実に密閉するように形成している。
図示例では、前記天板５０ａの中央部に型抜き孔ｉを形成して、この型抜き孔の孔縁から栓筒５２ａを垂下するとともに、この栓筒の下端を栓板５２ｂで閉塞することにより、前記ボス部５２を形成している。
また前記型抜き孔ｉを塞ぐ閉塞シート５４の外周部を、その型抜き孔の周囲の天板部分に接着している。
もっとも、ボス部５２の構造は、前記フランジ孔ｆを確実に閉鎖できれば、どのような構造でも構わない。
また図示例の栓筒５２ａは、その筒壁の外周面の上部前側から下部後側に亘って斜めに斜行する係合段部５３を有し、この係合段部を境として、その下側の筒壁部分を上側の筒壁部分より薄肉にしている。
前記係合段部５３は、前記口筒部４８ｅの上端面の少なくとも一部（図示例では、上端面の前側及び後側）に係止されている。 As shown in FIG. 2, the lid body 50 has a lid peripheral wall 50b hung vertically from the peripheral end of the top plate 50a.
Then, the rear end of the lid peripheral wall 50b is connected to the tubular peripheral wall 48 by the hinge 48c.
However, instead of such a hinge cap configuration, a screw cap configuration in which the lid peripheral wall 50b is screwed onto the tubular peripheral wall 48 may be used.
The inner surface of the lower end of the lid peripheral wall 50b is detachably fitted to the upper end of the tubular peripheral wall 48. In a preferred illustrated example, a recess that meshes with the locking claw 48b is formed so that the lid can be maintained in the closed state by resisting the increase in pressure in the measuring chamber M. Contrary to the illustrated example, a convex portion of the concave-convex engaging means may be formed on the peripheral wall side of the lid, and a concave portion may be formed on the peripheral wall side of the cylinder.
A finger hook portion 50c is attached to the front portion of the lid peripheral wall 50b.
On the rear side of the upper surface of the top plate 50a, an engaging recess r that meshes with the locking convex portion p when the lid 50 is opened may be formed. As a result, the open state of the lid body 50 is maintained. In addition, unlike the illustrated example, a locking convex portion may be formed on the lid side and an engaging concave portion may be formed on the auxiliary cylinder side.
A columnar boss portion 52 is vertically provided from the lower surface of the top plate 50a.
The boss portion 52 is tightly fitted to the inner surface of the mouth cylinder portion 48e. By doing so, the flange hole f of the inward flange-shaped top wall 48d is formed so as to be more reliably sealed.
In the illustrated example, a die-cutting hole i is formed in the central portion of the top plate 50a, the plug tube 52a is hung from the hole edge of the die-cutting hole, and the lower end of the plug tube is closed by the plug plate 52b. Therefore, the boss portion 52 is formed.
Further, the outer peripheral portion of the closing sheet 54 that closes the die-cutting hole i is adhered to the top plate portion around the die-cutting hole.
However, the structure of the boss portion 52 may be any structure as long as the flange hole f can be reliably closed.
Further, the stopper cylinder 52a of the illustrated example has an engaging step portion 53 that is obliquely oblique from the upper front side to the lower rear side of the outer peripheral surface of the cylinder wall, and below the engaging step portion 53 as a boundary. The cylinder wall part on the side is thinner than the cylinder wall part on the upper side.
The engaging step portion 53 is locked to at least a part of the upper end surface of the mouth cylinder portion 48e (in the illustrated example, the front side and the rear side of the upper end surface).

前記蓋体５０の天板５０ａを押し下げると、前記吐出ポンプ本体２２のステム３６から内容物が計量筒４４内へ送出され、その押下げ操作の回数に応じた液体が計量筒４４内に計量される。
例えば洗口液のように一度に使用する液量が比較的多い場合には、吐出ポンプ２０を複数回作動させればよいが、この場合に、前記閉鎖状態で操作回数が一定回数を超えると、計量室Ｍが高圧化するために、吐出ポンプ２０を操作させることができなくなる。
従って、利用者が誤って所要回数を超えて内容液を計量室Ｍ内へ吐出してしまうことを防止することができる。
また計量中に内向きフランジ状頂壁４８ｄのフランジ孔ｆはボス部５２で閉鎖されたままであるから、誤って容器を倒すなどしても、周囲に液体がこぼれることがない。
計量作業が終了したときには、図４に示すように、蓋体５０を開蓋する。そして内容物が洗口液である場合には、口筒部５０に口を付けて、そのまま口腔内を洗浄すればよい。 When the top plate 50a of the lid 50 is pushed down, the contents are sent out from the stem 36 of the discharge pump main body 22 into the measuring cylinder 44, and the liquid corresponding to the number of pressing operations is weighed into the measuring cylinder 44. To.
For example, when the amount of liquid used at one time is relatively large, such as mouthwash, the discharge pump 20 may be operated a plurality of times, but in this case, when the number of operations exceeds a certain number in the closed state, Since the pressure of the measuring chamber M is increased, the discharge pump 20 cannot be operated.
Therefore, it is possible to prevent the user from accidentally discharging the content liquid into the measuring chamber M more than the required number of times.
Further, since the flange hole f of the inward flange-shaped top wall 48d remains closed by the boss portion 52 during weighing, the liquid does not spill around even if the container is accidentally tilted.
When the weighing operation is completed, the lid 50 is opened as shown in FIG. When the content is a mouthwash, the oral cavity may be washed as it is by attaching a mouth to the mouth tube portion 50.
