Description

本発明は、容器内の内容物を一回使用する分だけ取り出すのに好適な定量注出器に関するものである。   The present invention relates to a quantitative dispenser suitable for taking out the contents in a container for a single use.

育毛剤の如き薬液等、一回の使用量が定められたものは、容器内の内容物を取り出すに際しては計量する必要があり、従来は、中栓に配置された円筒部を適宜上下動させて第一弁及び第二弁を交互に開閉することで容器内の内容物を計量筒部に流し込み、該計量筒部内の内容物を注出口を通して外部に排出するようにしていた（特許文献１参照）。
特開２００２−３３７９１０号公報 For liquids such as hair restorers that have a fixed amount of use, it is necessary to weigh them before taking out the contents in the container. Conventionally, the cylindrical part placed on the inner plug is moved up and down appropriately. By alternately opening and closing the first valve and the second valve, the contents in the container are poured into the measuring cylinder, and the contents in the measuring cylinder are discharged to the outside through the spout (Patent Document 1). reference).
JP 2002-337910 A

ところで、従来のこの種の定量注出容器は、計量に係わる内容物を注出している最中に不用意な力が作用すると容器と計量筒部とを隔絶する弁が簡単にスライドしてしまうこともあって、この場合、計量筒部内に容器内の内容物が流れ込んでしまい定量注出ができないおそれがあった。   By the way, in this type of conventional quantitative dispensing container, if an inadvertent force is applied during the dispensing of the contents related to measurement, the valve that isolates the container from the measuring cylinder part easily slides. In this case, the contents in the container flow into the measuring cylinder and there is a possibility that the quantitative dispensing cannot be performed.

本発明の課題は簡便な操作のもとで計量を行なうことが可能で、計量に係わる内容物のみを確実に注出できる新規な定量注出器を提案するところにある。   An object of the present invention is to propose a novel quantitative dispenser capable of performing weighing under a simple operation and capable of reliably dispensing only contents related to weighing.

本発明は、容器内の内容物の定量取り入れを可能とする貯溜空間を備え、先端開口を通して貯溜空間内の内容物を注出する定量注出器であって、
容器内の内容物を取り入れる窓孔を有し容器の口部に固定保持する外筒と、この外筒の内側に回動自在に挿入、嵌合し外筒の窓孔との連通を可能とする窓孔を有する内筒と、この内筒の一端につながり該内筒及び外筒と協働してその内側に貯溜空間を形成するとともに該貯留空間内の内容物を先端開口を通して注出する注出ヘッドとを備え、
前記注出ヘッドの先端開口に、該先端開口を通り抜け外部に向けて突出する頭部を有しその基部を先端開口の内側端縁に接触させて該先端開口を閉塞状態に維持する一方、該頭部を貯溜空間に向けて押し込んで該先端開口を開放する弁体を設けたことを特徴とする定量注出器である。 The present invention is a quantitative dispenser comprising a storage space that enables the quantitative incorporation of the contents in the container, and for dispensing the contents in the storage space through the tip opening,
Enables communication between the outer cylinder that has a window hole for taking in the contents in the container and is fixedly held at the mouth of the container, and the outer cylinder that is rotatably inserted and fitted inside the outer cylinder. An inner cylinder having a window hole to be connected to one end of the inner cylinder, and in cooperation with the inner and outer cylinders, a storage space is formed on the inner side, and the contents in the storage space are poured out through the tip opening. With a dispensing head,
The tip opening of the dispensing head has a head that projects through the tip opening and protrudes to the outside, and the base is brought into contact with the inner edge of the tip opening to keep the tip opening closed. A quantitative dispenser comprising a valve body that pushes the head toward a storage space to open the tip opening.

上記の構成になる定量注出器においては、前記貯溜空間内に、弁体を支持する弾性部材を配置することができる。   In the quantitative dispenser configured as described above, an elastic member that supports the valve element can be disposed in the storage space.

また、上記の注出器においては、前記注出ヘッドを覆い隠して外筒のベースにねじ止めし、その回動にて、注出ヘッドを内筒とともに供回りさせて外筒の窓孔と内筒の窓孔を連通させるカバーを配置するのが好ましい。   Further, in the above-described dispenser, the dispensing head is covered and screwed to the base of the outer cylinder, and by its rotation, the dispensing head is rotated together with the inner cylinder to form the window hole of the outer cylinder. It is preferable to arrange a cover for communicating the window hole of the inner cylinder.

注出ヘッドを回転させて外筒と内筒の窓孔を相互に合致、連通させてその窓孔を通して容器内の内容物を貯溜空間内に取り入れることで簡単に計量が行なえ、注出ヘッドの回転にて外筒の窓孔と内筒の窓孔を相互にずらし（不一致）て外筒の窓孔を閉じることで貯溜空間内への流れ込みを防止する。   By rotating the dispensing head, the window holes of the outer cylinder and the inner cylinder are aligned and communicated with each other, and the contents in the container can be taken into the storage space through the window hole, allowing easy weighing. By rotating (shifting) the window hole of the outer cylinder and the window hole of the inner cylinder relative to each other by rotation, the window hole of the outer cylinder is closed to prevent inflow into the storage space.

注出ヘッドの先端開口に弾性支持した弁体により計量に係わる内容物の適量注出が可能となる。   The valve body elastically supported at the tip opening of the dispensing head can dispense an appropriate amount of contents related to measurement.

以下、図面を用いて本発明をより具体的に説明する。
図１（ａ）（ｂ）は本発明にしたがう定量注出器を容器の口部に装着した例で示したものであり、図１（ａ）は平面図であり、図１（ｂ）は側面を断面で示した図である。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 (a) and 1 (b) show an example in which a quantitative dispenser according to the present invention is attached to the mouth of a container, FIG. 1 (a) is a plan view, and FIG. It is the figure which showed the side surface in the cross section.

図における１は内容物を収納する容器、２は外筒である。この外筒２はその側壁に容器１内の内容物を取り入れる窓孔２ａと、容器１の口部１ａにねじ止め又はアンダーカット嵌合により固定される基部２ｂを有する。   In the figure, 1 is a container for storing contents, and 2 is an outer cylinder. The outer cylinder 2 has a window hole 2a for taking the contents in the container 1 into its side wall, and a base 2b fixed to the mouth 1a of the container 1 by screwing or undercut fitting.

また、３は外筒２の内側に抜き出し不能、回転自在に挿入され、密に嵌合する有底筒状の内筒である。この内筒３は底部に外筒２とアンダーカット等の手段により嵌合する突出部を有するとともに、側壁には外筒２の窓孔２ａとの連通を可能とする窓孔３ａを有している。   Reference numeral 3 denotes a bottomed cylindrical inner cylinder that cannot be extracted inside the outer cylinder 2 and is rotatably inserted and closely fits. The inner cylinder 3 has a projecting portion which is fitted to the outer cylinder 2 by means such as undercut at the bottom, and a window hole 3a which allows communication with the window hole 2a of the outer cylinder 2 on the side wall. Yes.

４は内筒３の一端（露出端）に回動不能につながり該内筒３及び外筒２と協働してその内側に貯溜空間Ｍを形成する注出ヘッドである。この注出ヘッド４はその先端に貯溜空間Ｍ内の内容物の注出を可能とする先端開口４ａを有している。   A dispensing head 4 is connected to one end (exposed end) of the inner cylinder 3 so as not to rotate and cooperates with the inner cylinder 3 and the outer cylinder 2 to form a storage space M inside thereof. The dispensing head 4 has a distal end opening 4a that allows the contents in the storage space M to be dispensed at the distal end.

５は注出ヘッド４の先端開口４ａに設けられた弁体、６は弁体５と一体成形されそれを貯溜空間Ｍ内（内筒２の内側段部等を利用する）にて支持する弾性部材（ばね等）、そして、７は注出器全体を覆うカバーである。   5 is a valve body provided at the tip opening 4a of the dispensing head 4, and 6 is an elastic body that is formed integrally with the valve body 5 and supports it in the storage space M (using the inner step portion of the inner cylinder 2). A member (spring or the like), and 7 is a cover that covers the entire dispenser.

弁体５は先端開口４ａを通り抜け外部に向けて突出する溝付きの頭部５ａを有しその基部５ｂを弾性部材６の反発力により先端開口４ａの内側端縁に押圧、接触させて該先端開口４ａを閉塞状態に維持する一方、該頭部５ａを弾性部材６の反発力に抗して貯溜空間Ｍに向けて押し込むことで溝部を介して先端開口４ａを開放することができるようになっている。なお、頭部５ａに形成される溝は一本以上形成されていればよく、その数は任意であり、内容物の粘度や吐出量等に合わせて本数や大きさ等が適宜に設定される。   The valve body 5 has a grooved head portion 5a protruding through the tip opening 4a and projecting outward, and the base portion 5b is pressed and brought into contact with the inner edge of the tip opening 4a by the repulsive force of the elastic member 6. While the opening 4a is kept closed, the tip opening 4a can be opened through the groove portion by pushing the head portion 5a toward the storage space M against the repulsive force of the elastic member 6. ing. In addition, the groove | channel formed in the head 5a should just be formed 1 or more, The number is arbitrary, A number, a magnitude | size, etc. are set suitably according to the viscosity, discharge amount, etc. of the contents. .

外筒２の先端で注出ヘッド４を回転させると該注出ヘッド４につながる内筒３は外筒２の内側で回動することになり、この回動にて外筒２の窓孔２ａと内筒３の窓孔３ａを相互に合致、連通させる。   When the dispensing head 4 is rotated at the tip of the outer cylinder 2, the inner cylinder 3 connected to the dispensing head 4 is rotated inside the outer cylinder 2. By this rotation, the window hole 2 a of the outer cylinder 2 is rotated. And the window hole 3a of the inner cylinder 3 are matched and communicated with each other.

この状態で図２に示す如く容器を反転させると、窓孔２ａ、３ａを通して容器１内の内容物が貯溜空間Ｍ内に取り込まれ、これにより内容物の計量がなされる。   When the container is inverted in this state as shown in FIG. 2, the contents in the container 1 are taken into the storage space M through the window holes 2a and 3a, and the contents are weighed.

計量後に注出ヘッド４を再度回転させて内筒３の窓孔３ａをずらして外筒２の窓孔２ａを閉じると貯溜空間Ｍは密閉されることとなり、容器１がどのような姿勢にあろとも貯溜空間Ｍ内には所定量の内容物が保持される。   When the dispensing head 4 is rotated again after the measurement and the window hole 3a of the inner cylinder 3 is shifted to close the window hole 2a of the outer cylinder 2, the storage space M is sealed, and the container 1 is in any posture. In both cases, a predetermined amount of contents are held in the storage space M.

貯溜空間Ｍ内の内容物を注出するには、図３に示すように、注出ヘッド４の先端開口４ａから突出する弁体５の頭部５ａを塗布すべき面に押しつける。そうすると、弁体５の基部５ｂが先端開口４ａの内側端縁から離反して該先端開口４ａが開放され溝部を介して貯溜空間Ｍ内の内容物が注出されることとなる。   In order to pour out the contents in the storage space M, as shown in FIG. 3, the head 5a of the valve body 5 protruding from the tip opening 4a of the pour head 4 is pressed against the surface to be coated. Then, the base 5b of the valve body 5 is separated from the inner edge of the tip opening 4a, the tip opening 4a is opened, and the contents in the storage space M are poured out through the groove.

弁体５の頭部５ａを塗布すべき面から離すと弾性部材６の復元力により基部５ｂが先端開口４ａの内側端縁にすぐさま接触して内容物の注出が停止する。   When the head portion 5a of the valve body 5 is separated from the surface to be coated, the base portion 5b immediately contacts the inner edge of the tip opening 4a by the restoring force of the elastic member 6, and the dispensing of the contents stops.

注出ヘッド４と内筒３とをつなぐ手段としては具体的に、リブとこのリブに係合する溝部（スプライン等）を適用することができるが、内筒３を確実に回動させることができるものであればリブと溝部を利用したものには限定されない。   Specifically, as a means for connecting the dispensing head 4 and the inner cylinder 3, a rib and a groove (spline or the like) engaged with the rib can be applied. However, the inner cylinder 3 can be reliably rotated. If possible, it is not limited to those using ribs and grooves.

また、弁体５の頭部５ａは、内容物を効率良く注出するために外径を小さくしておくこともできる。弁体５と弾性部材６は一体成形したものとして説明したが、別体ものとして構成してもよい。   Moreover, the head 5a of the valve body 5 can also have a small outer diameter in order to pour out the contents efficiently. Although the valve body 5 and the elastic member 6 have been described as being integrally molded, they may be configured as separate bodies.

外筒２の窓孔２ａはそれが開状態にあるか、閉状態にあるかを把握しやすくするため、開閉状態のそれぞれで注出ヘッド４の回転を停止するストッパーを設けるとともに、注出ヘッド４の外表面にはそれを明示するマークを付することができる。本実施例では、図１（ａ）に示したように、窓孔２ａ、３ａの連通位置（計量時）、非連通時（注出時）を外部より目視可能とするため、外筒２の側壁より突出するフランジ部には計量、注出等の文字を、また、注出ヘッド４の側壁にはそれに適合するマークを、成形、印刷あるいはホットスタンプ等の方法により設ける。   The window hole 2a of the outer cylinder 2 is provided with a stopper for stopping the rotation of the dispensing head 4 in each of the open and closed states in order to make it easy to grasp whether the window hole 2a is in the open state or the closed state. The outer surface of 4 can be marked with a mark. In this embodiment, as shown in FIG. 1 (a), in order to make the communication position (when measuring) and non-communication (when dispensing) the window holes 2a and 3a visible from the outside, Characters such as metering and pouring are provided on the flange portion protruding from the side wall, and marks suitable for it are provided on the side wall of the pouring head 4 by a method such as molding, printing or hot stamping.

図４（ａ）（ｂ）は本発明にしたがう他の実施の形態を示した図である。
この例は、注出ヘッド４を覆い隠して外筒２の基部２ｂにねじ止めするカバー８を設けた構造のものである。このカバー８は、その内側に注出ヘッド４を取り囲む環状体８ａを備えている。 4 (a) and 4 (b) are diagrams showing another embodiment according to the present invention.
In this example, a cover 8 is provided that covers and covers the dispensing head 4 and is screwed to the base 2 b of the outer cylinder 2. The cover 8 includes an annular body 8a that surrounds the dispensing head 4 on the inside thereof.
