Description

本願の発明は、中空容器内に収容した液体を注出するのに、ピストンを往復動させて吸い上げる注出ポンプを中空容器の口頸部に装着した液体注出ポンプ付きの中空容器に係わるもので、中でも、使用済みとなって廃棄する中空容器の分別処理を不要として、回収して再利用するのに適した縦型の往復動式の液体注出ポンプを備えた中空容器に関するものである。  The invention of the present application relates to a hollow container with a liquid dispensing pump in which a dispensing pump that sucks and sucks up a piston by reciprocatingly moving the liquid contained in the hollow container is attached to the neck of the hollow container. In particular, the present invention relates to a hollow container equipped with a vertical reciprocating liquid dispensing pump suitable for collection and reuse without making it necessary to separate and discard used hollow containers. .

従来の中空容器に収容された洗剤やシャンプーあるいは種々の化粧品等の粘性溶液を中空容器から取り出して使用するのに、最近は、中空容器の開口部に装着した注出ポンプを押圧操作することにより内容液を注出するようにした液体容器が、多用されるようになってきている。  In order to take out a viscous solution such as detergent, shampoo or various cosmetics contained in a conventional hollow container from the hollow container, recently, by pressing the dispensing pump attached to the opening of the hollow container, Liquid containers designed to pour content liquids are becoming increasingly used.

そして、このような液体容器に装着された注出ポンプとしては、中空容器本体の口頸部の外周に嵌合した筒状蓋体を貫通して容器内へ垂設させたシリンダからなる吸引部と、該シリンダの内部にピストンを上下動させる作動部材とからポンプ本体が構成されており、前記作動部材を蔓巻きバネからなる付勢部材を介して上下動せしめて、容器内に収容された液体を前記シリンダの下端部に設けた吸い込み弁を介してシリンダ内に吸い上げて、加圧することによりシリンダの上端部に設けた吐出弁と噴射ヘッド部を介して噴射ノズルから外部へ注出するようにしたものが一般的である。  And, as a dispensing pump attached to such a liquid container, a suction part comprising a cylinder penetrating a cylindrical lid fitted to the outer periphery of the mouth neck of the hollow container body and penetrating into the container And an operating member that moves the piston up and down inside the cylinder, and the pump body is moved up and down via an urging member made of a vine spring and accommodated in a container. Liquid is sucked into the cylinder through a suction valve provided at the lower end of the cylinder and pressurized to be discharged from the injection nozzle to the outside through a discharge valve and an injection head provided at the upper end of the cylinder. The ones made are common.

ところで、このような液体注出ポンプは、前記作動部材を上下動させるための操作機構部の違いから、実開平1−78548号や実公昭63−2119号公報に記載するように噴射ヘッド部を手先で直接に押圧して上下動操作せしめる縦型の往復動式の注出ポンプと、実公昭60−26853号や特公昭61−141号公報に記載するようにレバーを指先により引き寄せることに上り上下動操作せしめるトリガー式の注出ポンプとの二種類の形式の注出ポンプに大別される。  By the way, such a liquid pouring pump has an ejection head portion as described in Japanese Utility Model Laid-Open No. 1-78548 and Japanese Utility Model Publication No. 63-2119 because of the difference in the operation mechanism portion for moving the operating member up and down. A vertical reciprocating pouring pump that is pressed directly by the hand and operated to move up and down, and the lever is pulled by the fingertip as described in Japanese Utility Model Publication Nos. 60-26853 and 61-141. It is roughly divided into two types of pumping pumps, which are a trigger type pumping pump that operates up and down.

しかし、前者の縦型の往復動式のものは、容器を台の上に置くか、片方の手で持ってから押圧ヘッド部を一方の手先で押圧しなければならず、やや不便な点はあるが、ポンプの構造が簡単で組み立てが容易であるから、製造コストを低く抑えることができて、また、粘度の高い溶液を注出するのに適しているのに対して、後者のトリガー形式のものは、容器ごと片手で持ってレバーを引くことにより内容液を簡単に注出することができて便利ではあるが、ポンプの構造がやや複雑組み立てに手間取り、製造コストが高くなり、また、あまり粘度が高すぎる溶液を注出するのには不向きであるという難点がある等の種々の理由から、一般的には縦型をした往復動式のものが多く用いられている。  However, the former vertical type reciprocating type must place the container on the table or hold it with one hand and then press the pressing head part with one hand. Although the pump structure is simple and easy to assemble, the manufacturing cost can be kept low, and it is suitable for pouring out a highly viscous solution. Although it is convenient that the liquid can be easily poured out by holding the container with one hand and pulling the lever, the structure of the pump is somewhat complicated and complicated, increasing the manufacturing cost, In general, a vertical reciprocating type is often used for various reasons such as being unsuitable for pouring a solution having a too high viscosity.

このような従来から多用されいる縦型の往復動ポンプの一般的な例としては、図6に示すように、容器本体32の口頸部32aに螺着した蓋体33により容器内に垂設する合成樹脂でできたシリンダ35の下端部に形成された弁座35bに金属製のボール35aが密着するように設けて吸い込み弁を形成し、また、前記シリンダ内に上下動可能に嵌合した筒状ピストン36aを有する合成樹脂製ステム36の上端部に形成された弁座36bに金属製ボール36cが密着するように設けて吐出弁を形成してポンプ本体を形成すると共に、前記ステム上端部に押圧ヘッド部38aと噴射ノズル37とを有する合成樹脂製の噴射ヘッド38を嵌合、固定して注出ポンプ31を形成したものがある。  As a typical example of such a conventional vertical reciprocating pump, as shown in FIG. 6, a lid 33 screwed to the mouth / neck portion 32a of the container body 32 is suspended in the container. A suction valve is formed by providing a metal ball 35a in close contact with a valve seat 35b formed at the lower end of a cylinder 35 made of synthetic resin, and fitted into the cylinder so as to be movable up and down. A metal ball 36c is provided in close contact with a valve seat 36b formed at the upper end of a synthetic resin stem 36 having a cylindrical piston 36a to form a discharge valve to form a pump body, and the upper end of the stem The injection pump 31 is formed by fitting and fixing the injection head 38 made of synthetic resin having the pressing head portion 38 a and the injection nozzle 37.

上記のような構造をした注出ポンプ31は、その押圧ヘッド部38aをシリンダ内の金属スプリング39の弾性力に抗して押し下げる操作を行うと、ステム36が下方へ変位してシリンダー35内に充満している内容液を加圧すると共に、吸い込み弁のボール35cがシリンダー下端の開口部を閉じるので、加圧された内容液は吐出弁のボール36cを押し上げて開口して噴射ノズル37から吐出される。
次いで、押圧ヘッド部38aの押圧操作を停止すると、噴射ヘッド38はスプリングの弾性復元力により元の位置に復帰して、吐出弁のボール36cがステム上端部の吐出路を閉じるので、シリンダー35内が負圧となって容器内の溶液をシリンダ内に吸い上げて、次の噴射操作に備える構成になっている。
In the pouring pump 31 having the above-described structure, when the pressing head portion 38a is pushed down against the elastic force of the metal spring 39 in the cylinder, the stem 36 is displaced downward into the cylinder 35. The filled content liquid is pressurized and the suction valve ball 35c closes the opening at the lower end of the cylinder, so that the pressurized content liquid pushes up the discharge valve ball 36c to open and is discharged from the injection nozzle 37. The
Next, when the pressing operation of the pressing head portion 38a is stopped, the ejection head 38 is returned to its original position by the elastic restoring force of the spring, and the discharge valve ball 36c closes the discharge path at the upper end of the stem. Becomes a negative pressure, sucks the solution in the container into the cylinder, and prepares for the next injection operation.

ところで、近年になって洗剤等の注出容器に限らず、合成樹脂を用いた種々の液体容器が多用されるようになった結果、使用済みとなった空の容器が大量に廃棄されるようになるにつれて、これらの容器は大量のゴミとなって集められるが、その処理について社会的な環境面からの対策が求められるようになり、また、これらは限りある地球資源は有効に利用すべきであるとの動きが出てきて、使用済みとなった容器の再生利用が必要になってきた。  By the way, in recent years, not only detergent dispensing containers, but also various liquid containers using synthetic resins have been frequently used. As a result, a large number of used empty containers are discarded. As these containers are collected as large amounts of garbage, social and environmental measures are required for their disposal, and these limited earth resources should be used effectively. It has become necessary to recycle used containers.

そして、従来から行われていた容器等の合成樹脂製品を回収して処理する方法としては、回収された合成樹脂製品はそのまま焼却処理されるか、または、破砕してから圧縮してペレット状の固形燃料にしたものを補助燃料として燃焼させるのが一般的な方法であったものが、最近になって、合成樹脂成形品に用いる原料樹脂にしたり、あるいは、繊維製品の原料として再生する方法が採られるように
なってきた。
And as a method of recovering and processing a synthetic resin product such as a conventional container, the recovered synthetic resin product is incinerated as it is, or crushed and then compressed into a pellet form Although it was a common method to burn a solid fuel as an auxiliary fuel, recently, there is a method of using it as a raw material resin for synthetic resin molded products or regenerating it as a raw material for textile products. It has come to be adopted.

このように使用済みの合成樹脂容器等を原料樹脂として再生利用するに当たって採られている一般的な方法としては、回収した合成樹脂容器等を破砕機により小さく破砕した後、該細片を洗浄、乾燥させたものを押し出し機により溶融押し出してペレット状に成形してから、該ペレットをそのまま直接に押し出しあるいは射出成形装置に供給して成形するか、または、該ペレットにバージン原料ペレットを混合してから各種の成形を行う等の各用途に応じた方法があるが、これらは再生ペレットに樹脂以外の金属等の異物が混入していないということを前提としたものである。  As a general method that has been taken to recycle a used synthetic resin container or the like as a raw material resin, the recovered synthetic resin container or the like is crushed into small pieces by a crusher, and then the pieces are washed. The dried product is melt-extruded by an extruder and formed into a pellet shape, and then the pellet is directly extruded or supplied to an injection molding apparatus for molding, or the pellet is mixed with virgin raw material pellets. However, these methods are based on the premise that foreign materials such as metals other than resin are not mixed in the recycled pellets.

しかし、前記した発明のように従来から使用されている注出ポンプには、スプリングやボール弁に金属部品が使用されているのが一般的であり、このような従来の注出ポンプを備えた容器を回収して破砕機で破砕すれば、破砕片の中には金属異物が混入することになるので、各種の成形に使用可能な再生樹脂とするには、樹脂片中の異物を除去することが必要となる。
そして、一般に破砕した樹脂片に混入した異物を除去するには、比重差を利用した沈降分離法や風力選別法、磁性を利用した磁気選別法等が用いられているが、異物を完全に分離するには手間と時間がかかるのと同時に多額の設備費を要し、また、使用済みの容器等に金属が混ざっていると破砕機を傷めるので補修費用が嵩むことにもなる。
However, as in the above-described invention, the conventional pumping pumps generally use metal parts for springs and ball valves, and are equipped with such conventional pumping pumps. If the container is collected and crushed with a crusher, metal foreign matter will be mixed in the crushed piece. To make a recycled resin that can be used for various moldings, remove the foreign matter in the resin piece. It will be necessary.
And generally, in order to remove foreign matter mixed in the crushed resin pieces, sedimentation separation method using specific gravity difference, wind separation method, magnetic separation method using magnetism, etc. are used, but the foreign matter is completely separated. This requires labor and time, and at the same time, requires a large amount of equipment. In addition, if a metal is mixed in a used container or the like, the crusher is damaged, and repair costs increase.

そこで、廃棄される合成樹脂製の注出容器を再生利用し易いものとするためには、金属部品を一切使用せずに形成された注出ポンプを用いて液体注出容器を構成することが考えられる。
そして、そのようなものとしては既に特開平6−191571号や実願平2−77008号公報に記載するようなものが提案されており、これらの注出容器は、粘性が高い液体を注出するには動作が不安定に成りがちで、またベローズ等の構造が複雑で成形に際してやや面倒な点があった。
Therefore, in order to make it easy to recycle the discarded plastic resin dispensing container, it is possible to configure the liquid dispensing container using a dispensing pump formed without using any metal parts. Conceivable.
And as such a thing, what is already described in Unexamined-Japanese-Patent No. 6-191571 and Japanese Patent Application No. 2-77008 is proposed, These pouring containers pour liquid with high viscosity. Therefore, the operation tends to become unstable, and the structure of the bellows and the like is complicated and there are some troublesome points in molding.

上記のような点を改良して、注出ポンプの作動部材を上方へ付勢する弾性部材をエラストマーにより形成すると共に、その他の全構成部材も合成樹脂で形成した注出ポンプを備えた注出容器を、出願人は特開平10−235242号公報として提案している。
上記発明の注出容器は、図7に示すように、容器本体の口頸部に装着した筒状蓋体12を貫いてシリンダ15を垂設すると共に、該シリンダ内に挿通したステム16にピストン18を設けてなる作動部材を上下動可能にして、前記シリンダ下端部にポペット17により形成した吸い込み弁を設けて、容器内の溶液を吸い上げて噴射するようにした注出容器に於いて、前記筒状蓋体12の天板部の内寄りに起立する筒状部12bの外面へ嵌着させた弾性部材13の基筒部13aから弾性筒部13bを起立させて、該弾性筒部の上端部を内側下方へ湾曲させて、該湾曲部の下端に嵌合短筒部13cを設けてエラストマー製の弾性部材13を形成すると共に、前記嵌合短筒部13cを、シリンダ15内から上方へ起立せしめた作動部材のステム16と、押圧ヘッド14から垂下してステム先端に嵌合した嵌合筒14bとが形成する液体吐出用起立管の上部外面に固着させて、前記弾性部材43により作動部材を上方へ付勢させてステム46を上下動可能とした注出ポンプを備えたものである。
The above-described improvements have been made so that the elastic member for urging the operation member of the extraction pump upward is made of an elastomer, and all other components are also made of synthetic resin. The applicant has proposed a container as Japanese Patent Laid-Open No. 10-235242.
As shown in FIG. 7, the dispensing container according to the present invention has a cylinder 15 penetrating through a cylindrical lid 12 attached to the mouth and neck of the container body, and a stem 16 inserted into the cylinder. In the dispensing container in which the actuating member provided with 18 is movable up and down, a suction valve formed by the poppet 17 is provided at the lower end of the cylinder, and the solution in the container is sucked up and sprayed. The elastic cylinder part 13b is raised from the base cylinder part 13a of the elastic member 13 fitted to the outer surface of the cylindrical part 12b standing inward of the top plate part of the cylindrical lid 12, and the upper end of the elastic cylinder part And the fitting short tube portion 13c is provided at the lower end of the bending portion to form the elastomeric elastic member 13, and the fitting short tube portion 13c is moved upward from the inside of the cylinder 15. Steering stem 16 of the actuating member Then, the stem is fixed to the upper outer surface of the riser pipe for liquid discharge formed by the fitting cylinder 14b suspended from the pressing head 14 and fitted to the stem tip, and the operating member is urged upward by the elastic member 43. 46 is provided with a pumping pump that can move up and down.

上記発明の注出ポンプは、ステム16からなる作動部材を上下動可能付勢した弾性部材13や吸い込み弁17等を、その他のポンプ構成部材及び容器本体と同様な合成樹脂で形成したので、使用済みとなった注出容器を破砕して再生利用する際に、樹脂以外の不純物が混入することはない。
しかし、このような構造の注出ポンプは、作動部材を上下動可能に付勢させる弾性部材13の弾性筒状部13bを、押圧ヘッド14のステム嵌合筒14bの凹溝内に湾曲せしめるようにして設けたものであるから、弾性部材13の伸縮量や伸縮力その他が制約されたり、また、正確に組み立てるには細心の注意を要する等の問題がある。
Since the pumping pump of the above invention is formed of the same synthetic resin as the other pump constituent members and the container body, the elastic member 13, the suction valve 17 and the like that urge the actuating member consisting of the stem 16 to move up and down are used. Impurities other than resin are not mixed when crushing and recycling recycled dispensing containers.
However, in the dispensing pump having such a structure, the elastic cylindrical portion 13b of the elastic member 13 that urges the operating member to move up and down is curved in the concave groove of the stem fitting cylinder 14b of the pressing head 14. Therefore, there is a problem that the amount of expansion and contraction, the expansion and contraction force, etc. of the elastic member 13 are restricted, and careful attention is required for accurate assembly.

内溶液を注出するための注出ポンプを装着した液体注出容器が使用済みとなり廃棄された後で、該容器を回収して再生利用するのが容易な構造にした注出容器を形成するために、前記液体中空容器に装着する注出ポンプに於ける付勢部材のスプリングや逆止弁等の部品に金属材料を使用せずに、注出ポンプ全体の部品を容器本体と同様な合成樹脂により成形したものを用いることにより、使用済みとなって回収された液体注出容器を破砕機で破砕して再生利用する際に、破砕機が損傷したり、破砕片に樹脂以外の不純物が混在する恐れがないようにした液体注出容器を提供する。  After the liquid dispensing container equipped with a dispensing pump for dispensing the internal solution is used and discarded, the dispensing container is formed so that the container can be easily recovered and recycled. Therefore, the parts of the entire pumping pump are synthesized in the same manner as the container body without using metal materials for the springs and check valves of the biasing member of the pumping pump installed in the liquid hollow container. By using a molded product made of resin, the crusher may be damaged or the impurities other than the resin may be present on the crushed pieces when the used liquid recovery container is crushed with a crusher and recycled. Provided is a liquid dispensing container that is not likely to be mixed.

本願の発明は、合成樹脂製中空容器の口頸部に螺着した円筒状の蓋体により容器本体内にシリンダを垂設した状態で固定すると共に、該シリンダ内の底部に吸い込み弁を設けてなるポンプ本体と、前記シリンダ内に吐出弁やピストンを有するステムを上方へ付勢状態で上下動可能に嵌合せしめて突設すると共に、該ステムの上端部に噴射ノズルを有する噴射ヘッド部を嵌合して固定した作動部材とら構成してなる縦型の往復動式の液体注出ポンプに於いて、前記吸い込み弁部及び吐出弁を合成樹脂で形成して、また、前記作動部材を上下動可能に付勢する弾性部材をポンプ本体と同種の合成樹脂またはエラストマー樹脂等で形成すると共に、弾性部材を上部の肉厚部と下部のやや肉厚の支持部と中間の弾性変形部とからなる容易に弾性変形が可能な構造に形成して、組み立てが容易で、安価に製造可能な構造にした縦型の往復動式液体注出ポンプに構成することにより、該液体注出ポンプを備えた液体中空容器を、安価で、再生利用が容易であるものに形成する。  The invention of the present application is fixed in a state in which the cylinder is suspended in the container body by a cylindrical lid body screwed to the mouth and neck of the synthetic resin hollow container, and a suction valve is provided at the bottom of the cylinder. A pump body and a stem having a discharge valve and a piston are fitted into the cylinder so as to be movable upward and downward, and an injection head portion having an injection nozzle is fitted to the upper end of the stem. In a vertical reciprocating liquid dispensing pump constituted by a fixed operating member, the suction valve portion and the discharge valve are formed of synthetic resin, and the operating member is moved up and down. The elastic member to be urged is formed of the same type of synthetic resin or elastomer resin as the pump body, and the elastic member is composed of an upper thick part, a lower thick support part, and an intermediate elastic deformation part. Easily elastic deformation By forming a vertical reciprocating liquid dispensing pump that has a structure capable of being assembled easily and can be manufactured at low cost, a liquid hollow container equipped with the liquid dispensing pump is provided. It is cheap and easy to recycle.

本願発明は、上記に説明したように液体注出装置を構成するポンプ本体、吐出弁を有する作動部材、作動部材を付勢する弾性部材等の全てを、ポンプ本体と同一または同種の熱可塑性合成樹脂により形成したので、このような注出装置を備えた液体注出容器が使用済みとなって廃棄された後に、回収して再生利用するに際して、ポンプ本体部分を分別する必要がなくて、回収した液体注出容器をそのまま破砕機にかけて破砕しても、従来のように樹脂の以外に金属等の異なる材料が用いていないので、破砕機を傷めたり、再生ペレット化する際に、樹脂以外の異物が混入する恐れもないので、分別廃棄をする必要がなくて再生利用を行うことが容易である。
また、弾性部材が外部から見えるようにしたものでは、容器の他の部分とは異なる色の材料を用いて形成することにより、色彩の変化に富んだ容器を形成することが可能になり、また、キャラクター形状にすることにより嗜好性のある容器にすることができる。
As described above, the invention of the present application is the same or the same type of thermoplastic composite as the pump body, including the pump body constituting the liquid dispensing device, the operating member having the discharge valve, and the elastic member for biasing the operating member. Since it is made of resin, there is no need to separate the pump body part when collecting and recycling after the liquid dispensing container equipped with such a dispensing device has been used and discarded. Even if the liquid discharge container is crushed by crushing as it is, different materials such as metal are not used other than resin as in the past, so when crushing the machine or regenerating pellets, Since there is no possibility that foreign matter is mixed, there is no need to separate and discard, and it is easy to recycle.
In addition, in the case where the elastic member is visible from the outside, it is possible to form a container rich in color change by forming it using a material having a different color from the other parts of the container. By making the character shape, it is possible to make a container with taste.

熱可塑性合成樹脂をブロー成形により成形してなる液体中空容器の口頸部の外周部に螺着する蓋体に液体注出ポンプを装着するために、蓋体2を円筒状に形成すると共に円筒21内周面にネジ山21aを形成して、また、該円筒状蓋体の天板部の周縁部に上方へ立設する筒状体22を設けて、該筒状壁の内側に平坦なフランジ状の頂壁部23と該フランジ状の頂壁の内端部を上方へ起立せしめて逆U

本願発明は、上記のような構成をした蓋体2の前記逆U字状の筒状内壁25と筒状外壁24とから形成されるシリンダ嵌合筒部27に、中空容器本体と同一または同種の熱可塑性合成樹脂で成形してなるシリンダ5の上端部を嵌合せしめて固定すると共に、該シリンダ内の底部には吸い込み弁を構成する樹脂製のポペット7を設けてポンプ本体を形成する。  In the present invention, the cylinder fitting cylinder portion 27 formed of the inverted U-shaped cylindrical inner wall 25 and the cylindrical outer wall 24 of the lid body 2 configured as described above is the same as or similar to the hollow container body. The cylinder 5 formed by the thermoplastic synthetic resin is fitted and fixed at the upper end, and a resin poppet 7 constituting a suction valve is provided at the bottom of the cylinder to form a pump body.

このように形成したポンプ本体のシリンダ5内に、ピストン8を有する下部筒体6aと吐出弁を有する上部筒体6bとからなるステム6を摺動自在に嵌合せしめて、該ステムの先端部分を蓋体2の挿通口28から突出せしめると共に、該ステム6の先端部に噴射ノズル4aを有する噴射ヘッド部4の嵌合筒部4bを嵌合せしめて固定して押圧操作が可能な作動部材に形成する。
その際に、前記蓋体2の天板部と噴射ヘッド部4の下面との間に、前記作動部材を上方へ付勢するエラストマー樹脂からなる筒状の弾性部材3を、ステム6と嵌合筒部4bを囲むようにして装着して液体注出ポンプを構成する。
A stem 6 consisting of a lower cylinder 6a having a piston 8 and an upper cylinder 6b having a discharge valve is slidably fitted into the cylinder 5 of the pump body formed as described above, and the distal end portion of the stem is attached. It is made to project from the insertion port 28 of the lid 2 and is formed into an operating member capable of being pressed by fitting and fixing the fitting cylinder portion 4b of the ejection head portion 4 having the ejection nozzle 4a to the tip portion of the stem 6. To do.
At that time, a cylindrical elastic member 3 made of an elastomer resin that biases the operating member upward is fitted between the top plate portion of the lid 2 and the lower surface of the ejection head portion 4 and the stem 6. A liquid dispensing pump is configured by being mounted so as to surround the cylindrical portion 4b.

前記噴射ヘッド部4は、図1及び図2に見るように、上記蓋体3の筒状体22の内周面に係合する大きさの外筒部4cとステム6の上端部が嵌合する大きさの内径を有する嵌合筒部4bと液体を噴射するためのノズル4aとを有しており、前記外筒部4cの内周面と嵌合筒部4bの外周面とで形成される周溝4dには、前記作動部材を上下動可能に付勢した筒状の弾性部材3の上端部3eが嵌着されるような構造にすると共に、前記外筒部4cの内周面には弾性部材3が抜けないように係止する係止突起4eが設けられている。  As shown in FIGS. 1 and 2, the ejection head portion 4 is fitted with an outer cylindrical portion 4 c of a size that engages with the inner peripheral surface of the cylindrical body 22 of the lid 3 and an upper end portion of the stem 6. And a nozzle 4a for injecting liquid, and is formed by an inner peripheral surface of the outer cylindrical portion 4c and an outer peripheral surface of the fitting cylindrical portion 4b. The circumferential groove 4d has a structure in which an upper end portion 3e of a cylindrical elastic member 3 that urges the actuating member so as to move up and down is fitted, and on the inner circumferential surface of the outer cylindrical portion 4c. Is provided with a locking projection 4e for locking the elastic member 3 so as not to come off.

また、前記弾性部材3は、図1に示すように、その下部部分が前記蓋体2の筒状体22と内筒壁24との間に形成された円周状の凹溝26内に嵌合するやや大径の円筒部分3aと、上部部分が噴射ヘッド部4の外筒部4cと嵌合筒部4bとの間に形成された円周状の凹溝4dに嵌合するやや小径の円筒部分3bとを、中間部分のテーパー部分3cで連結して概略筒状体に形成されたものである。
そして、前記弾性部材3は、上部部分が肉厚で、中間部分が肉薄で、下部部分がやや肉厚で、安定した形に弾性変形するように形成されているが、肉厚の形状の変化の付け具合により、ヘッドを押圧した時の弾性部材が点線で示すように変形する形状は異なったものとなるようにすることもできる。
As shown in FIG. 1, the elastic member 3 has a lower portion fitted in a circumferential concave groove 26 formed between the cylindrical body 22 and the inner cylindrical wall 24 of the lid body 2. The slightly larger diameter cylindrical portion 3a and the upper portion are fitted in a circumferential concave groove 4d formed between the outer cylinder portion 4c and the fitting cylinder portion 4b of the ejection head portion 4. The cylindrical portion 3b is connected by a tapered portion 3c at an intermediate portion, and is formed into a substantially cylindrical body.
The elastic member 3 is formed such that the upper part is thick, the middle part is thin, the lower part is slightly thick, and is elastically deformed into a stable shape. Depending on the condition, the shape of deformation of the elastic member when the head is pressed may be different as shown by the dotted line.

そして、前記弾性部材3は、適正な弾性力と反発力とを有するエラストマー樹脂あるいはポンプ本体と同種の樹脂で射出成形等により成形されるが、該弾性部材3は、図1に見るように下方の大径の円筒部分3aはやや肉厚の支持部で、中間のテーパー部分3cは肉薄の弾性変形し易い構造に形成されると共に、上方の小径の円筒部分3bは肉厚の変形しにくい構造に形成されており、また、前記弾性部材3の上端部と下端部には、それぞれフランジ状の突起片3d,3eが設けられていて、変形防止と抜け止めとの機能を持ち合わせている。
前記弾性部材3が蓋体2の嵌合筒部27及び噴射ヘッド4の嵌合筒部4Bと嵌合する面に外気と連通する隙間が設けられるが、図1に於いては、記弾性部材の突起片3dと蓋体2とが接する面に外気を導入するための間隙3gが形成されている。
しかし、外気導入孔は、このように限定されるものではなくて、外気を遮断するようにステム6を包んで設ける弾性部材3の適当な箇所に穿孔して形成することも可能である。
The elastic member 3 is formed by injection molding or the like with an elastomer resin having an appropriate elastic force and repulsive force or a resin of the same type as the pump main body. The large-diameter cylindrical portion 3a is a slightly thick support portion, the intermediate taper portion 3c is formed in a thin and easily elastically deformable structure, and the upper small-diameter cylindrical portion 3b is thin and difficult to deform. In addition, flange-shaped protrusions 3d and 3e are provided at the upper end and the lower end of the elastic member 3, respectively, and have functions of preventing deformation and retaining.
A gap communicating with the outside air is provided on the surface where the elastic member 3 is engaged with the fitting cylinder part 27 of the lid body 2 and the fitting cylinder part 4B of the ejection head 4, but in FIG. A gap 3g for introducing outside air is formed on the surface where the projection piece 3d and the lid 2 are in contact with each other.
However, the outside air introduction hole is not limited to this, and can be formed by perforating the elastic member 3 provided around the stem 6 so as to block the outside air.

本願発明は、上記のようにして構成した注出ポンプを設けた筒状蓋体2を、中空容器本体の口頚部1aに螺着して内容液の注出が可能な容器を構成する。
そして、容器内に収容した溶液を注出するに際しては、前記注出ポンプの噴射ヘッド部4を押圧して作動部材を上下動させることにより、シリンダ5内が負圧になって吸入弁が開いて容器体内の液がシリンダ内に導入され、図1に示すようになって注出準備が完了する。
The present invention constitutes a container capable of dispensing the content liquid by screwing the cylindrical lid body 2 provided with the dispensing pump constructed as described above to the neck portion 1a of the hollow container body.
When the solution stored in the container is dispensed, the cylinder 5 is negatively pressured by opening the suction valve by pressing the spray head 4 of the dispensing pump and moving the operating member up and down. Then, the liquid in the container is introduced into the cylinder, and the preparation for dispensing is completed as shown in FIG.

続いて、再び噴射ヘッド8を手先で押し下げると、弾性部材3のテーパー部分3cと大径の下部円筒部分3aとが圧縮変形して、図2に示すように作動部材が押し下げられた状態になるので、ポペット7が下降して吸入弁が閉じると同時にシリンダ5内の圧力が高くなって、加圧されたシリンダ内の溶液が吐出弁を押し開くので、溶液はステム6及び噴射ヘッド部4内の吐出路を通って、噴射ノズル4aから噴射するようにして注出される。  Subsequently, when the ejection head 8 is pushed down again by the hand, the tapered portion 3c of the elastic member 3 and the large-diameter lower cylindrical portion 3a are compressed and deformed, and the operating member is pushed down as shown in FIG. Therefore, the poppet 7 is lowered and the suction valve is closed. At the same time, the pressure in the cylinder 5 is increased, and the pressurized solution in the cylinder pushes the discharge valve open, so that the solution is in the stem 6 and the ejection head unit 4. Is discharged from the injection nozzle 4a through the discharge passage.

次に、手先を噴射ヘッド部4から離して押圧状態が解除されると、弾性部材3の復元力により作動部材が上昇して、シリンダ6内が負圧化されるために吐出弁が閉じられて、吸い込み弁が開くので、再び容器内の溶液がシリンダ内に導入されると同時に、容器内には外気導入用の間隙3g及び吸気孔5aを通して外気が導入されるので、容器内の圧力は大気圧と等しくなって、次の注出操作が可能な状態になる。  Next, when the pressing state is released by moving the hand away from the ejection head portion 4, the operating member is raised by the restoring force of the elastic member 3, and the inside of the cylinder 6 is negatively pressurized, so the discharge valve is closed. Since the suction valve is opened, the solution in the container is again introduced into the cylinder, and at the same time, outside air is introduced into the container through the gap 3g for introducing outside air and the intake hole 5a. It becomes equal to the atmospheric pressure, and the next dispensing operation is possible.

上記した実施例に於いては、蓋体の構造を図1に示すように、円筒状蓋体2の頂壁周縁部に胴部から連続するように筒状体22を起立せしめておいて、該筒状体22とその内側に設けた嵌合筒部の内筒壁24との間に形成される円周状の装着溝26内に弾性部材3の下端部のフランジ状の突起部3dを密着せしめて嵌着して、テーパ部分3cが安定して変形するようにした。
従って、噴射ヘッドが押し下げられた時に、弾性部材3は、外側が噴射ヘッド部4の外筒部4cと蓋体2の筒状体22とで覆われた状態で圧縮変形されるが、本願発明は、注出ポンプを容器に装着する蓋体および作動部材を付勢する弾性部材は、必ずしも上記したような構造に限定する必要はなくて、次のような構造にしてもよい。
In the above-described embodiment, as shown in FIG. 1, the structure of the lid body is such that the cylindrical body 22 is erected so as to be continuous from the body portion at the peripheral edge of the top wall of the cylindrical lid body 2. A flange-like protrusion 3d at the lower end of the elastic member 3 is provided in a circumferential mounting groove 26 formed between the cylindrical body 22 and the inner cylindrical wall 24 of the fitting cylindrical portion provided on the inner side thereof. The taper portion 3c is stably deformed by closely fitting.
Therefore, when the ejection head is pushed down, the elastic member 3 is compressed and deformed in a state where the outer side is covered with the outer cylinder portion 4c of the ejection head portion 4 and the cylindrical body 22 of the lid body 2. The elastic member that urges the lid and the actuating member for mounting the dispensing pump on the container is not necessarily limited to the above-described structure, and may be structured as follows.

実施例2.
本願発明の変形例一つとして、実施例1で用いた円筒状をした蓋体2の天板部の周縁部に起立した筒状体22に代えて、図3に示したように、高さを低くした環状突起52を設けた蓋体2Aとなして、該環状突起52を弾性部材3Aの下端部に形成した環状突起の下面に係合して嵌合せしめるように形成したので、弾性部材が直接に見えるようになるから、色彩や特徴ある形状にすることにより容器に変化をもたらすことが可能になる。
また、実施例1で用いた弾性部材3の下部円筒部3aの下端部を、図3に示したように、外向きに設けたフランジ状の突起部32dの下面に前記蓋体2Aの環状突起52の内壁面に嵌合可能な嵌合筒部32fを設けると共に、該蓋体の環状突起52面に係合する逆L字状の係合面を形成して、弾性部材3Aの大径の下部円筒部32aとなして、該下部円筒部32aと、小径の上部円筒部32bの上端部に外向きのフランジ状の突起部32eを設けると共に、噴射ヘッド部4の周溝4dに嵌合可能に形成した上部円筒部32bとを中間のテーパー部32cにより連結したので、図4に示すように円筒状の弾性部材3Aは変形が容易になる。
Example 2
As a modification of the present invention, instead of the cylindrical body 22 standing on the peripheral edge of the top plate portion of the cylindrical lid body 2 used in the first embodiment, as shown in FIG. Since the lid 2A is provided with the annular projection 52 having a lowered height, the annular projection 52 is formed so as to be engaged with and fitted into the lower surface of the annular projection formed at the lower end of the elastic member 3A. Since it becomes visible directly, it is possible to change the container by making it a color or a characteristic shape.
Further, as shown in FIG. 3, the lower end portion of the lower cylindrical portion 3a of the elastic member 3 used in the first embodiment is formed on the lower surface of the flange-shaped projection portion 32d provided outward, and the annular projection of the lid 2A. A fitting cylinder portion 32f that can be fitted to the inner wall surface of 52 is provided, and an inverted L-shaped engagement surface that engages with the surface of the annular protrusion 52 of the lid is formed, so that the elastic member 3A has a large diameter. The lower cylindrical portion 32a is provided with an outward flange-shaped projection 32e at the upper end of the lower cylindrical portion 32a and the small-diameter upper cylindrical portion 32b, and can be fitted into the circumferential groove 4d of the ejection head portion 4. Since the upper cylindrical portion 32b formed in the above is connected by the intermediate tapered portion 32c, the cylindrical elastic member 3A is easily deformed as shown in FIG.

上記のように形成した弾性部材3Aの上部円筒部32bの外向きのフランジ状突起部32eを、前記発明と同様に噴射ヘッド部4の筒状体4bの内周面と嵌合筒部4cの外周面とで形成される周溝4dに嵌着すると共に、前記上部円筒部32bの内面が嵌合筒部4bの外周面に密着するように固定する。そして、蓋体2Aの天板から突出したステム6に前記噴射ヘッド部4の嵌合筒部4bを嵌合せしめると同時に、弾性部材3Aの下部円筒部32aの下端のフランジ状突起部32dが蓋体2Aの環状突起52面に係合するようにして、突起部下面の逆L字状の嵌合筒部32fを前記環状突起52内に嵌合せしめて、前記弾性部材3Aにより作動部材の突出したステム6と嵌合筒部4bを包むようにして固定して液体注出ポンプを構成する。このような構成にして注出ポンプは組み立ても容易に行うことができて、内容液を注出する際に噴射ヘッド4を押圧すると、図4に示すように、弾性部材3Aが圧縮変形して、ステム6が押し下げられてシリンダー内が加圧状態になって内容液が注出される。  As described above, the outward flange-like protrusion 32e of the upper cylindrical portion 32b of the elastic member 3A formed as described above is connected to the inner peripheral surface of the cylindrical body 4b of the ejection head portion 4 and the fitting cylindrical portion 4c. The upper cylindrical portion 32b is fixed so that the inner surface of the upper cylindrical portion 32b is in close contact with the outer peripheral surface of the fitting cylindrical portion 4b. Then, at the same time that the fitting cylinder portion 4b of the ejection head portion 4 is fitted to the stem 6 protruding from the top plate of the lid 2A, the flange-like projection portion 32d at the lower end of the lower cylindrical portion 32a of the elastic member 3A is covered by the lid. An inverted L-shaped fitting tube portion 32f on the lower surface of the protruding portion is fitted into the annular protrusion 52 so as to engage with the annular protrusion 52 surface of the body 2A, and the operating member protrudes by the elastic member 3A. The stem 6 and the fitting cylinder portion 4b are fixed so as to wrap, and a liquid dispensing pump is configured. With such a configuration, the dispensing pump can be easily assembled. When the ejection head 4 is pressed when dispensing the content liquid, the elastic member 3A is compressed and deformed as shown in FIG. The stem 6 is pushed down, the inside of the cylinder is pressurized, and the content liquid is poured out.

As shown in FIG. 5, the outward flange-like projection 2e provided at the upper end of the upper cylindrical portion 2b of the elastic member 3A used in the second embodiment is inwardly flange-like projection. 42e is formed so as to be fitted in the mounting groove 4d of the ejection head portion 4, and an outward flange-like projection portion 42d is provided at the lower end portion of the lower cylindrical portion 42a, and a lid is formed on the lower surface of the projection portion. Can be fitted to the inner surface of the annular projection 52 of the lid body 2A by forming a fitting cylindrical portion 42f that can be fitted to the annular projection 52 of the lid body.

A shaped elastic member 3B is formed.

上記のように形成した弾性部材3Bは、小径の上部円筒部42bのフランジ状突起部42eを、噴射ヘッド部4の外筒部4cの内周面と嵌合筒部4bの外周面とで形成される周溝4d内に嵌着すると共に、前記円筒部42bの外面が前記外筒部4cの内周面に密着するように固定してから、蓋体2Aの天板から突出したステム6に噴射ヘッド部4の嵌合筒部4bを嵌合せしめると共に、弾性部材3Bの下部円筒部42aの下端のフランジ状突起部42dが蓋体2Aの環状突起52の端面に係合するようにして、突起部の下面の逆L字状の嵌合筒部42fを環状突起52内面に嵌合せしめて、前記弾性部材3Bにより作動部材の突出したステム6を包むようにして固定する。  In the elastic member 3B formed as described above, the flange-like protrusion 42e of the small-diameter upper cylindrical portion 42b is formed by the inner peripheral surface of the outer cylindrical portion 4c of the ejection head portion 4 and the outer peripheral surface of the fitting cylindrical portion 4b.
