Description

【０００１】
【発明の属する技術分野】
本発明は、トリガーないし作動部材の操作により容器体内の液体をシリンダ内へ吸い上げてノズルから噴出させる液体噴出器において、液体と反応せずかつ環境・廃棄物問題に対応しうる玉弁を設けたものである。
【０００２】
【従来の技術】
例えば、実開平１−１７４０７３号には、作動部材による押下げ式の液体噴出器において、シリンダの底部に設けた吸込み弁を玉弁で形成した液体噴出器が開示されている。
【０００３】
【発明が解決しようとする課題】
玉弁を形成する球状弁体は通常、鋼等の金属で作られているが、容器体内の液体の種類によっては球状弁体並びに液体が劣化するおそれがあった。
また、球状弁体は液体噴出器内部に組み込まれているため、環境対策上の観点から再資源化のために望ましいとされる他の合成樹脂材との分別廃棄が困難であった。
さらに、球状弁体は金属自体で形成されているため、廃棄物処分場において粉砕機の刃を破損するおそれがあった。
【０００４】
本発明の第１目的は、合成樹脂材と無機質材とを混練して球状弁体を形成することにより、液体との間で化学反応が生ずることを防止すると共に、困難な分別廃棄を不要にし、かつ、粉砕機の刃の破損を未然に防止しようというものである。
【０００５】
本発明の第２の目的は、球状弁体の比重を１よりも大とすることによって液体中での速やかな沈降を可能とし、吸込み弁の確実かつ可及的速やかな閉弁を達成しようというものである。
【０００６】
本発明の第３の目的は、無機質材をセラミック粉末等から選定することにより、球状弁体の成形をより一層容易にしようというものである。
【０００７】
本発明の第４の目的は、トリガーを合成樹脂材から形成したバネ材によって付勢することにより、金属と合成樹脂材との分別を不要にするというものである。
【０００８】
本発明の第５の目的は、作動部材を合成樹脂材から形成したバネ材によって付勢することにより、金属と合成樹脂材との分別を不要にするというものである。
【０００９】
【課題を解決するための手段】
第１の手段として、トリガーの操作により吸込み弁を介して容器体内の液体をシリンダ内へ吸い上げ、吐出弁を介してノズルから噴出させる液体噴出器において、上記トリガー４は合成樹脂材から形成したバネ材５によって前方付勢するとともに、上記吸込み弁又は吐出弁の一方又は双方を玉弁によって形成し、かつ該玉弁の球状弁体１０、２７を、比重が１以下の合成樹脂材と比重が１．２以上の無機質材とを混練してこれらの合計比重が１よりも大の球状弁体に形成し、更に上記無機質材を、セラミック粉末、硫酸バリウム、タルク又はアルミナの中から選定するとともに、その無機質材の粒径を５μｍから１００μｍの範囲とした。
【００１０】
第２の手段として、シリンダ内へ嵌合させた作動部材のノズル付き押下げヘッドを操作することにより吸込み弁を介して容器体内の液体をシリンダ内へ吸い上げ、吐出弁を介してノズルから噴出させる液体噴出器において、上記作動部材２９は合成樹脂材から形成したバネ材３８によって上方付勢するとともに、上記吸込み弁又は吐出弁の一方又は双方を玉弁によって形成し、かつ該玉弁の球状弁体１０、２７を、比重が１以下の合成樹脂材と比重が１．２以上の無機質材とを混練してこれらの合計比重が１よりも大の球状弁体に形成し、更に上記無機質材を、セラミック粉末、硫酸バリウム、タルク又はアルミナの中から選定するとともに、その無機質材の粒径を５μｍから１００μｍの範囲とした。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照しながら説明する。
本発明に係る液体噴出器は、トリガー操作により液体を吸い上げて噴出させるトリガー式液体噴出器と作動部材の操作により液体を吸い上げて噴出させる縦型ポンプ式液体噴出器とのいずれの液体噴出器にも適用しうるが、ここではまず本発明を前者に適用した例につき説明する。
【００１５】
図１において、１はトリガー式液体噴出器で、容器体口頸部外面へ嵌合させた装着筒２の上端内から起立筒３を起立している。起立筒３から図示しない射出筒とシリンダとを前方突出し、シリンダ前部からトリガー４を揺動自在に垂下している。５はトリガー４及びピストンを前方付勢するバネ材で、前端をトリガー４に、また、後端を起立筒３基部に、それぞれ係合させている。さらに、シリンダからピストン脚棒６を前方突出してその前端をトリガー４後面へ係合させている。
【００１６】
７は起立筒３内面へ嵌着させた吸上げパイプ嵌合筒で、該吸上げパイプ嵌合筒下端から吸上げパイプ８を垂下すると共に、吸上げパイプ８よりも上方の吸上げパイプ嵌合筒７筒部分内面に下部小径のテーパ状吸込み弁座９を突設し、その上面に球状弁体１０を載置して玉弁による吸込み弁を形成すると共に、その下面に吸上げパイプ８上端面を当接させている。
【００１７】
ここまでは従来のトリガー式液体噴出器と同様の構成であるが、本発明にあっては、球状弁体１０を金属自体で形成することなく、合成樹脂材を基調とした材質によって形成した点で従来のものと異なる。すなわち、本発明は球状弁体１０を、合成樹脂材と無機質材との混練により形成する点にその特徴を備えている。
【００１８】
以下、この点につきさらに詳細に説明すると、合成樹脂材としては比重１以下の材質を使用し、また、無機質材としては比重１．２以上の材質を使用し、かつ、これらの合計比重が水の比重１よりも大となるようにする。合計比重を１よりも大とする理由は次の通りである。
【００１９】
すなわち、液体噴出後、トリガー４の復帰動作によりシリンダ内は負圧化するが、この負圧化により球状弁体１０がテーパ状吸込み弁座９から離隔して容器体内の液体が吸上げられる。そして、シリンダ内負圧が解消し液体の吸上げが完了すると、球状弁体１０は液体内を沈降してテーパ状吸込み弁座９を閉じる必要があるが、この球状弁体１０の比重が１以下であると、液体の比重も１以下であることから、球状弁体１０は浮遊してテーパ状吸込み弁座９を閉じることが不可能か、あるいは沈降するにしても沈降速度が緩慢でテーパ状吸込み弁座９を直ちに閉じることができないからである。
【００２０】
実施例として、合成樹脂材としてのポリプロピレンに無機質材としてアルミナを２０〜５０重量％の割合で混練したもの、あるいはポリプロピレンに無機質材としてセラミック粉末を２０〜５０重量％の割合で混練したものが挙げられる。アルミナとセラミック粉末のそれぞれのポリプロピレンに対する混練割合を２０重量％以上としたのは合計比重を１以上にするためであり、また、５０重量％以下としたのは成形可能限度だからである。
【００２１】
ポリプロピレン以外の合成樹脂材として、ポリエチレン等のポリオレフィン等を挙げることができ、また、アルミナ及びセラミック粉末以外の無機質材として硫酸バリウム及びタルクを挙げることができる。
なお、無機質材の粒径としては成形容易性を考慮して５〜１００μｍの範囲にあるのが好ましい。
【００２２】
次に、本発明を縦型ポンプ式液体噴出器に適用した例について説明する。
図２において、２０は縦型ポンプ式液体噴出器で、容器体口頸部外面へ嵌合させた装着筒２１の上端から内向きフランジ２２を介してガイド筒２３を起立し、シリンダ２４上端に付設した外向きフランジを、内向きフランジ２２下面に係合させてシリンダ２４を垂下している。
【００２３】
シリンダ２４下端から吸上げパイプ嵌合筒２５を垂下し、該吸上げパイプ嵌合筒上端から下部小径のテーパ状吸込み弁座２６を突設しその上面に球状弁体２７を載置して玉弁による吸込み弁を形成すると共に、その下面に吸上げパイプ２８上端面を当接させている。
【００２４】
２９は作動部材で、シリンダ２４内へ上方付勢させて嵌合させた、ステム３０下端に筒状ピストン３１を有し、かつ、ステム３０上端に形成した上部小径のテーパ部３０ａ外面へノズル付き押下げヘッド３２の上端内に垂設した短筒状吐出弁座３３を当接自在ならしめている。さらに、ステム３０外面へ案内筒３４を嵌着させ、該案内筒３４の上端部に有底の囲成筒３５を形成し、該囲成筒３５内にノズル付き押下げヘッド３２内の内筒３６を垂下している。
【００２５】
さらに、ノズル付き押下げヘッド３２は内筒３６の外周に外筒３７を垂下し、該外筒下端をガイド筒２３内面へ上下動自在に係合させている。３８は作動部材２９を上方付勢するバネ材で、そのバネ上端を囲成筒３５の上端へ係合させると共に、そのバネ下端を内向きフランジ２２上面へ当接させている。
【００２６】
このような縦型ポンプ式液体噴出器において、作動部材２９を押し下げるとシリンダ２４内の液体は高圧化するが、ステム３０上端面と案内筒３４上端面とを合計した上側受圧面積の方が筒状ピストン３１下端部の下側受圧面積よりも大であるため、ステム３０が下降してテーパ部３０ａが短筒状吐出弁座３３から離隔し液体がノズルから噴出する。
【００２７】
一方、吸込み弁を形成する球状弁体２７は作動部材２９の押下げ時にはテーパ状吸込み弁座２６に押し付けられているが、作動部材２９の上昇によりシリンダ２４内が負圧化するとテーパ状吸込み弁座２６から離隔し、シリンダ負圧が解消すると液体内を沈降してテーパ状吸込み弁座２６へ着座する。
【００２８】
縦型ポンプ式液体噴出器２０の上記構成は従来公知のものと同様の構成であり、本発明にあっては、吸込み弁を形成する球状弁体２７が従来公知のものと異なっている。本発明にあっては、球状弁体２７を金属自体で形成することなく、合成樹脂材を基調とした材質によって形成した点で従来公知のものと異なっている。すなわち、本発明は球状弁体２７を、合成樹脂材と無機質材との混練によって形成する点に特徴を有するが、この球状弁体２７の構成は上記第１の実施形態とまったく同一の構成であるから、重複を避けるためその説明を省略する。
【００２９】
以上は本発明を、トリガー式液体噴出器と縦型ポンプ式液体噴出器とのそれぞれの吸込み弁座を形成する玉弁に適用した例について説明したが、これに限らず吐出弁を玉弁で形成したものについても適用できるこというまでもない。
【００３０】
なお、トリガー式液体噴出器におけるトリガー４を前方付勢するバネ材５と、縦型式液体噴出器における作動部材２９を上方付勢するバネ材３８とのそれぞれは合成樹脂材によって形成するのが好ましい。再資源化の観点から望ましいとされる金属材と合成樹脂材との困難な分別廃棄を不要にするという請求項４及び５記載の発明の目的に沿うからである。
【００３１】
【発明の効果】
本発明の液体噴出器は、球状弁体を合成樹脂材と無機質材とにより形成したので容器体の中味に対して安定であり、したがって球状弁体及び容器体中味の劣化のおそれといった問題の解決が図れる。また、球状弁体を従来のように金属自体で形成することなく、合成樹脂材と無機質材とによって形成するので、環境対策上の観点から再資源化のために望ましいとされる金属材と合成樹脂材との困難な分別作業が不要になりそのまま廃棄することができ、したがってコスト削減が可能になる。さらに、球状弁体を金属自体で形成しないため、廃棄物処理場における粉砕機の刃の破損が防止される。
【００３２】
又本発明の液体噴出器は、球状弁体の比重を１よりも大とするため、液体中での速やかな沈降が可能となり吸込み弁の確実かつ可及的速やかな閉弁が達成される。
【００３３】
又本発明の液体噴出器は、無機質材をセラミック粉末等から選定するため、球状弁体の成形がより一層容易になる。
【００３４】
更に本発明の液体噴出器は、トリガーを上方付勢するバネ材を合成樹脂材から形成するため、金属材と合成樹脂材との困難な分別が不要になる。
【００３５】
更に本発明の液体噴出器は、作動部材を前方付勢するバネ材を合成樹脂材から形成するため、金属材と合成樹脂材との困難な分別が不要になる。

BACKGROUND OF THE INVENTION
The present invention provides a ball valve that does not react with the liquid and can cope with environmental and waste problems in a liquid ejector that sucks the liquid in the container into the cylinder by the operation of the trigger or the operating member and ejects it from the nozzle. Is.
[0002]
[Prior art]
For example, Japanese Utility Model Laid-Open No. 1-174073 discloses a liquid ejector in which a suction valve provided at the bottom of a cylinder is formed by a ball valve in a push-down type liquid ejector by an operating member.
[0003]
[Problems to be solved by the invention]
The spherical valve body forming the ball valve is usually made of metal such as steel, but the spherical valve body and the liquid may be deteriorated depending on the type of liquid in the container.
Further, since the spherical valve body is incorporated in the liquid ejector, it is difficult to separate and dispose of it with other synthetic resin materials that are desirable for recycling from the viewpoint of environmental measures.
Furthermore, since the spherical valve body is made of metal itself, there is a risk of damaging the blade of the pulverizer at the waste disposal site.
[0004]
The first object of the present invention is to prevent a chemical reaction with a liquid by kneading a synthetic resin material and an inorganic material to form a spherical valve body, and eliminate the need for difficult separation and disposal. In addition, it is intended to prevent damage to the blade of the pulverizer.
[0005]
The second object of the present invention is to enable rapid sedimentation in a liquid by making the specific gravity of the spherical valve body greater than 1, and to achieve the reliable and prompt closing of the suction valve. Is.
[0006]
The third object of the present invention is to further facilitate the formation of the spherical valve body by selecting the inorganic material from ceramic powder or the like.
[0007]
The fourth object of the present invention is to eliminate the need for separating the metal and the synthetic resin material by biasing the trigger with a spring material formed from the synthetic resin material.
[0008]
A fifth object of the present invention is to eliminate the need for separating the metal and the synthetic resin material by biasing the operating member with a spring material formed from the synthetic resin material.
[0009]
[Means for Solving the Problems]
As a first means, in the liquid ejector that sucks the liquid in the container into the cylinder through the suction valve by the operation of the trigger and ejects the liquid from the nozzle through the discharge valve, the trigger 4 is a spring formed from a synthetic resin material. The material 5 is biased forward, and one or both of the suction valve and the discharge valve is formed by a ball valve, and the spherical valve bodies 10 and 27 of the ball valve have a specific gravity of a synthetic resin material having a specific gravity of 1 or less. 1.2 or more inorganic materials are kneaded to form a spherical valve body having a total specific gravity greater than 1, and the inorganic material is selected from ceramic powder, barium sulfate, talc or alumina. The particle size of the inorganic material was in the range of 5 μm to 100 μm .
[0010]
As a second means, the liquid in the container is sucked into the cylinder through the suction valve by operating the push-down head with the nozzle of the operating member fitted into the cylinder, and ejected from the nozzle through the discharge valve. In the liquid ejector, the actuating member 29 is biased upward by a spring material 38 formed of a synthetic resin material , and one or both of the suction valve and the discharge valve are formed by a ball valve, and a spherical valve of the ball valve The bodies 10 and 27 are kneaded with a synthetic resin material having a specific gravity of 1 or less and an inorganic material having a specific gravity of 1.2 or more to form a spherical valve body having a total specific gravity greater than 1, and the inorganic material. Was selected from ceramic powder, barium sulfate, talc or alumina, and the particle size of the inorganic material was in the range of 5 μm to 100 μm.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
The liquid ejector according to the present invention includes any one of a trigger type liquid ejector that sucks up and ejects liquid by a trigger operation and a vertical pump type liquid ejector that sucks up and ejects liquid by operating an operation member. Here, an example in which the present invention is applied to the former will be described first.
[0015]
In FIG. 1, reference numeral 1 denotes a trigger type liquid ejector, which erects an upright cylinder 3 from the upper end of a mounting cylinder 2 fitted to the outer surface of the container body neck. An injection cylinder (not shown) and a cylinder project forward from the upright cylinder 3, and the trigger 4 is suspended from the front of the cylinder in a swingable manner. A spring material 5 biases the trigger 4 and the piston forward, and the front end is engaged with the trigger 4 and the rear end is engaged with the upright cylinder 3 base. Further, the piston leg bar 6 protrudes forward from the cylinder, and its front end is engaged with the rear surface of the trigger 4.
[0016]
A suction pipe fitting cylinder 7 is fitted to the inner surface of the upright cylinder 3. The suction pipe 8 is suspended from the lower end of the suction pipe fitting cylinder, and the suction pipe fitting above the suction pipe 8 is fitted. A cylindrical small suction valve seat 9 is projected on the inner surface of the cylinder 7 and a spherical valve body 10 is placed on the upper surface thereof to form a suction valve by a ball valve, and on the lower surface of the suction pipe 8 The end face is in contact.
[0017]
Up to this point, the configuration is the same as that of the conventional trigger type liquid ejector. However, in the present invention, the spherical valve body 10 is not formed of metal itself, but is formed of a material based on a synthetic resin material. It is different from the conventional one. That is, the present invention is characterized in that the spherical valve body 10 is formed by kneading a synthetic resin material and an inorganic material.
[0018]
Hereinafter, this point will be described in more detail. As the synthetic resin material, a material having a specific gravity of 1 or less is used, and as the inorganic material, a material having a specific gravity of 1.2 or more is used, and the total specific gravity is water. So that the specific gravity is greater than 1. The reason why the total specific gravity is larger than 1 is as follows.
[0019]
That is, after the liquid is ejected, the pressure in the cylinder is reduced by the return operation of the trigger 4, but by this negative pressure, the spherical valve body 10 is separated from the tapered suction valve seat 9 and the liquid in the container body is sucked up. When the negative pressure in the cylinder is eliminated and the suction of the liquid is completed, the spherical valve body 10 needs to settle in the liquid and close the tapered suction valve seat 9, but the specific gravity of the spherical valve body 10 is 1 If it is below, the specific gravity of the liquid is also 1 or less, so that the spherical valve body 10 cannot float and close the tapered suction valve seat 9, or even if it sinks, the settling speed is slow and tapered. This is because the suction valve seat 9 cannot be closed immediately.
[0020]
Examples include those obtained by kneading alumina as a mineral material in a proportion of 20 to 50% by weight with polypropylene as a synthetic resin material, or those obtained by kneading ceramic powder as a mineral material in polypropylene in a proportion of 20 to 50% by weight. It is done. The reason why the kneading ratio of alumina and ceramic powder to polypropylene is 20% by weight or more is to make the total specific gravity 1 or more, and the reason why it is 50% by weight or less is the limit for molding.
[0021]
Examples of synthetic resin materials other than polypropylene include polyolefins such as polyethylene, and examples of inorganic materials other than alumina and ceramic powder include barium sulfate and talc.
The particle size of the inorganic material is preferably in the range of 5 to 100 μm in consideration of ease of molding.
[0022]
Next, an example in which the present invention is applied to a vertical pump type liquid ejector will be described.
In FIG. 2, reference numeral 20 denotes a vertical pump type liquid ejector. A guide cylinder 23 is erected from an upper end of a mounting cylinder 21 fitted to an outer surface of a container body mouth and neck through an inward flange 22, and The attached outward flange is engaged with the lower surface of the inward flange 22 to suspend the cylinder 24.
[0023]
A suction pipe fitting cylinder 25 is suspended from the lower end of the cylinder 24, a tapered suction valve seat 26 having a lower diameter is protruded from the upper end of the suction pipe fitting cylinder, and a spherical valve element 27 is placed on the upper surface thereof. While forming the suction valve by a valve, the upper end surface of the suction pipe 28 is made to contact | abut on the lower surface.
[0024]
Reference numeral 29 denotes an actuating member which has a cylindrical piston 31 at the lower end of the stem 30 and is fitted into the cylinder 24 by being biased upward, and a nozzle is provided on the outer surface of the upper small diameter tapered portion 30a formed at the upper end of the stem 30. A short cylindrical discharge valve seat 33 suspended from the upper end of the push-down head 32 is provided so as to be freely contactable. Further, a guide tube 34 is fitted to the outer surface of the stem 30, a bottomed surrounding tube 35 is formed at the upper end of the guide tube 34, and the inner tube in the pressing head 32 with the nozzle is formed in the surrounding tube 35. 36 is suspended.
[0025]
Further, the push-down head 32 with a nozzle hangs an outer cylinder 37 on the outer periphery of the inner cylinder 36 and engages the lower end of the outer cylinder with the inner surface of the guide cylinder 23 so as to be movable up and down. Reference numeral 38 denotes a spring material that biases the actuating member 29 upward. The upper end of the spring is engaged with the upper end of the surrounding cylinder 35, and the lower end of the spring is brought into contact with the upper surface of the inward flange 22.
[0026]
In such a vertical pump type liquid ejector, when the actuating member 29 is pushed down, the liquid in the cylinder 24 is increased in pressure, but the upper pressure receiving area obtained by adding up the upper end surface of the stem 30 and the upper end surface of the guide cylinder 34 is the cylinder. Since the lower pressure receiving area of the lower end of the cylindrical piston 31 is larger, the stem 30 is lowered, the tapered portion 30a is separated from the short cylindrical discharge valve seat 33, and the liquid is ejected from the nozzle.
[0027]
On the other hand, the spherical valve body 27 forming the suction valve is pressed against the tapered suction valve seat 26 when the operating member 29 is pushed down. However, when the pressure in the cylinder 24 is reduced by the raising of the operating member 29, the tapered suction valve 27 is pressed. When the cylinder is separated from the seat 26 and the negative pressure of the cylinder is eliminated, the liquid settles down and is seated on the tapered suction valve seat 26.
[0028]
The above-described configuration of the vertical pump type liquid ejector 20 is the same as that of a conventionally known one. In the present invention, the spherical valve body 27 forming the suction valve is different from the conventionally known one. In the present invention, the spherical valve body 27 is different from a conventionally known one in that it is made of a material based on a synthetic resin material without being made of metal itself. That is, the present invention is characterized in that the spherical valve body 27 is formed by kneading a synthetic resin material and an inorganic material. The configuration of the spherical valve body 27 is exactly the same as that of the first embodiment. Therefore, the description is omitted to avoid duplication.
[0029]
The above is an example in which the present invention is applied to a ball valve that forms the respective suction valve seats of the trigger type liquid ejector and the vertical pump type liquid ejector. Needless to say, it can be applied to the formed one.
[0030]
Each of the spring material 5 that biases the trigger 4 in the trigger type liquid ejector forward and the spring material 38 that biases the operating member 29 in the vertical type liquid ejector upward is preferably made of a synthetic resin material. . This is because the purpose of the inventions according to claims 4 and 5 is to eliminate the need for difficult separation and disposal of the metal material and the synthetic resin material, which are desirable from the viewpoint of recycling.
[0031]
【The invention's effect】
The liquid ejector of the present invention is stable with respect to the contents of the container body because the spherical valve body is formed of a synthetic resin material and an inorganic material, and thus solves the problem of the possibility of deterioration of the contents of the spherical valve body and the container body. Can be planned. In addition, the spherical valve body is made of a synthetic resin material and an inorganic material without being formed of the metal itself as in the prior art. Difficult separation work with the resin material becomes unnecessary and can be discarded as it is, so that cost reduction is possible. Furthermore, since the spherical valve body is not formed of the metal itself, breakage of the blade of the pulverizer at the waste disposal site is prevented.
[0032]
In addition, since the specific gravity of the spherical valve body is greater than 1, the liquid ejector of the present invention can quickly settle in the liquid, and the suction valve can be closed as reliably and as quickly as possible.
[0033]
In addition, since the liquid ejector of the present invention selects the inorganic material from ceramic powder or the like, the spherical valve body can be more easily formed.
[0034]
Furthermore, in the liquid ejector of the present invention , since the spring material that biases the trigger upward is formed from a synthetic resin material, it is not necessary to separate the metal material from the synthetic resin material.
