JP 2002-326044 A

しかしながら、前記従来の押下ヘッドでは、ノズル孔を開閉するために、例えば、装着筒部材や梃子部材等が設けられており、しかもこれらの部品を連動させる必要もあり、部品点数が多く、構造が複雑であるという問題があった。   However, in the conventional pressing head, for example, a mounting cylinder member, a lever member, and the like are provided in order to open and close the nozzle hole, and it is necessary to interlock these parts, and the number of parts is large and the structure is large. There was a problem of being complicated.

本発明は、上述した事情に鑑みてなされたものであって、その目的は、部品点数を低減し、構造の簡素化を図った上でノズル孔を開閉することができる押下ヘッドを提供することである。   The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a pressing head capable of opening and closing a nozzle hole after reducing the number of parts and simplifying the structure. It is.

上記課題を解決するために、この発明は以下の手段を提案している。
本発明に係る押下ヘッドは、上方付勢状態で押込み可能にステムを起立した吐出器に装着される押下ヘッドであって、周壁部に形成された貫通孔を通して前方に向けて開口すると共に後方に向けて延在し、且つ前記ステム内に連通する横筒を内部に有する有底筒状のヘッド本体と、前記横筒内に後方付勢状態で前進摺動可能に嵌合されたノズル筒部材と、前記横筒内に前後方向に沿って延設された開閉ピンと、が備えられ、該開閉ピンは、前記ノズル筒部材内に挿入されると共に、前記ノズル筒部材の前端部に形成されたノズル孔を閉塞していることを特徴とするものである。 In order to solve the above problems, the present invention proposes the following means.
A pressing head according to the present invention is a pressing head mounted on a discharger having a stem standing upright so as to be able to be pressed in an upward biased state, and opens toward the front through a through-hole formed in a peripheral wall portion, and rearward. A bottomed cylindrical head main body having a horizontal cylinder extending in the direction and communicating with the inside of the stem, and a nozzle cylinder member fitted in the horizontal cylinder so as to be slidable forward in a rearward biased state. And an open / close pin extending in the front-rear direction in the horizontal cylinder, and the open / close pin is inserted into the nozzle cylinder member and formed at the front end of the nozzle cylinder member The nozzle hole is closed.

本発明に係る押下ヘッドによれば、ステム内から横筒内に流入される内容物の液圧によってノズル筒部材が後方付勢力に抗して横筒内で前進させられる。これにより、ノズル筒部材のノズル孔が開閉ピンから離反し、ノズル孔が開口させられる。
そして、横筒内への内容物の流入が停止すると、ノズル筒部材が後方付勢力により横筒内で後退させられる。これにより、ノズル筒部材のノズル孔が開閉ピンに接近し、ノズル孔が閉塞させられる。 According to the pressing head according to the present invention, the nozzle cylinder member is advanced in the horizontal cylinder against the rear urging force by the hydraulic pressure of the contents flowing into the horizontal cylinder from the stem. Thereby, the nozzle hole of the nozzle cylinder member is separated from the opening / closing pin, and the nozzle hole is opened.
When the inflow of contents into the horizontal cylinder stops, the nozzle cylinder member is retracted in the horizontal cylinder by the rear biasing force. Thereby, the nozzle hole of a nozzle cylinder member approaches an opening-and-closing pin, and a nozzle hole is obstruct | occluded.

この結果、例えば装着筒部材や梃子部材等を設けるといった従来技術のような構成としなくても、ノズル孔を開閉することが可能になる。従って、ノズル孔を開閉可能な押下ヘッドの部品点数を低減し、構造の簡素化を図ることができる。   As a result, it is possible to open and close the nozzle holes without using a configuration as in the prior art such as providing a mounting cylinder member, a lever member, or the like. Therefore, the number of parts of the pressing head that can open and close the nozzle hole can be reduced, and the structure can be simplified.

また、本発明に係る押下ヘッドでは、前記ノズル筒部材には、前記横筒より柔軟な材質で形成されたシール筒部材が備えられ、前記シール筒部材は、前記横筒内に摺動可能に嵌合されていることが好ましい。   In the pressing head according to the present invention, the nozzle tube member is provided with a seal tube member made of a material more flexible than the horizontal tube, and the seal tube member is slidable in the horizontal tube. It is preferable that it is fitted.

この場合、シール筒部材が横筒より柔軟な材質で形成されているので、横筒とシール筒部材との間の液密性を向上することができる。このため、ノズル筒部材の外周面側を通って内容物が外部に漏出するのを抑制し、内容物を確実にノズル孔から吐出させることができる。   In this case, since the seal cylinder member is formed of a material that is more flexible than the horizontal cylinder, the liquid tightness between the horizontal cylinder and the seal cylinder member can be improved. For this reason, it can suppress that a content leaks outside through the outer peripheral surface side of a nozzle cylinder member, and can discharge a content from a nozzle hole reliably.

本発明に係る押下ヘッドによれば、部品点数を低減し、構造の簡素化を図った上でノズル孔を開閉することができる。   According to the pressing head according to the present invention, the nozzle hole can be opened and closed after the number of parts is reduced and the structure is simplified.

横筒６の前端開口部には、貫通孔５を通して挿通筒部材１２が装着されている。この挿通筒部材１２内には、ノズル筒部材８の前側部分が挿通されている。挿通筒部材１２には、周壁部４の外周面における貫通孔５の開口周縁部上に配置されるリング状の前端壁１３と、この前端壁１３の後面から後方に延設され、横筒６の前端開口部内及び貫通孔５内に嵌合される装着筒１４と、が備えられている。
なお、前端壁１３と装着筒１４とは同軸上に配設されている。また、前端壁１３の内径は装着筒１４の内径よりも小さく、前端壁１３の外径は装着筒１４の外径より大きくなっている。 An insertion tube member 12 is attached to the front end opening of the horizontal tube 6 through the through hole 5. A front portion of the nozzle cylinder member 8 is inserted into the insertion cylinder member 12.

And a mounting cylinder 14 fitted into the front end opening and the through hole 5.
The front end wall 13 and the mounting cylinder 14 are arranged coaxially. The inner diameter of the front end wall 13 is smaller than the inner diameter of the mounting cylinder 14, and the outer diameter of the front end wall 13 is larger than the outer diameter of the mounting cylinder 14.

ノズル筒部材８は、例えばＰＥ、ＰＰ等のポリオレフィン樹脂や、ＰＥＴ等のポリエステル樹脂等の合成樹脂材料で形成されたノズル筒本体８ｂを備えている。ノズル筒本体８ｂのうち、挿通筒部材１２から前方に突出した前端部は、前方に向かうに従って漸次縮径され、その前端にノズル孔１５が形成されている。また、ノズル筒本体８ｂの後部には、その径方向外方に向けて鍔部１６が突設されている。鍔部１６の外径は、挿通筒部材１２の装着筒１４の内径より大きく、且つ横筒６の内径よりも小さくなっている。   The nozzle cylinder member 8 includes a nozzle cylinder body 8b formed of a synthetic resin material such as a polyolefin resin such as PE or PP, or a polyester resin such as PET. In the nozzle cylinder body 8b, the front end portion protruding forward from the insertion cylinder member 12 is gradually reduced in diameter toward the front, and a nozzle hole 15 is formed at the front end. Further, a flange portion 16 projects from the rear portion of the nozzle cylinder main body 8b toward the radially outer side. The outer diameter of the flange portion 16 is larger than the inner diameter of the mounting cylinder 14 of the insertion cylinder member 12 and smaller than the inner diameter of the horizontal cylinder 6.

また、本実施形態では、ノズル筒部材８には、横筒６より柔軟な材質で形成されたシール筒部材１７が備えられ、このシール筒部材１７が、横筒６内に摺動可能に嵌合されている。図示の例では、シール筒部材１７は、ノズル筒本体８ｂより柔軟な材質で形成されている。
シール筒部材１７の材質としては、例えば、ニトリルゴム、ブチルゴム、シリコンゴム、熱可塑性エラストマー等の軟材質や、ウレタン等が挙げられる。 In this embodiment, the nozzle cylinder member 8 is provided with a seal cylinder member 17 made of a material more flexible than the horizontal cylinder 6, and the seal cylinder member 17 is slidably fitted into the horizontal cylinder 6. Are combined. In the illustrated example, the seal cylinder member 17 is formed of a material that is more flexible than the nozzle cylinder body 8b.
Examples of the material of the seal cylinder member 17 include soft materials such as nitrile rubber, butyl rubber, silicon rubber, and thermoplastic elastomer, and urethane.

図示の例では、シール筒部材１７は、ノズル筒本体８ｂの後端部の外周面に嵌合され、その前端縁が鍔部１６の後面に当接し、その後端部１７ａがノズル筒本体８ｂの後端縁８ａよりも後方に突出している。また、シール筒部材１７において、後端部１７ａは、この後端部１７ａより前側に位置する前側部分１７ｂより薄肉とされると共に、後方に向かうに従い漸次拡径している。そして、シール筒部材１７において、後端部１７ａの後端の外径は、前側部分１７ｂの外径よりも大きくなっており、シール筒部材１７のうち後端部１７ａの後端のみが横筒６の内周面に当接している。
なお、シール筒部材１７の後端部１７ａは、横筒６内において流通孔６ｃよりも前側に位置する部分に配設されている。 In the illustrated example, the seal tube member 17 is fitted to the outer peripheral surface of the rear end portion of the nozzle tube main body 8b, the front end edge thereof is in contact with the rear surface of the flange portion 16, and the rear end portion 17a is the nozzle tube main body 8b. It protrudes rearward from the rear edge 8a. Further, in the seal cylinder member 17, the rear end portion 17a is thinner than the front side portion 17b positioned in front of the rear end portion 17a and gradually increases in diameter toward the rear. In the sealing cylinder member 17, the outer diameter of the rear end of the rear end portion 17a is larger than the outer diameter of the front side portion 17b, and only the rear end of the rear end portion 17a of the sealing cylinder member 17 is a horizontal cylinder. 6 is in contact with the inner peripheral surface.
The rear end portion 17a of the seal cylinder member 17 is disposed in a portion located in front of the flow hole 6c in the horizontal cylinder 6.

また、挿通筒部材１２の前端壁１３とノズル筒本体８ｂの鍔部１６との間には、コイルスプリング１８が介在されており、このコイルスプリング１８によりノズル筒部材８が後方に付勢されている。   Further, a coil spring 18 is interposed between the front end wall 13 of the insertion tube member 12 and the flange portion 16 of the nozzle tube body 8b, and the nozzle tube member 8 is urged rearward by the coil spring 18. Yes.

開閉ピン９は、ノズル筒部材８内に挿入されると共に、ノズル孔１５を閉塞している。図示の例では、開閉ピン９は、横筒６の後端壁６ａから横筒６と同軸に、前方に向けて延設されている。
なお、ノズル筒本体８ｂの内周面と開閉ピン９の外周面との間には隙間が設けられている。 The open / close pin 9 is inserted into the nozzle cylinder member 8 and closes the nozzle hole 15. In the illustrated example, the open / close pin 9 extends from the rear end wall 6 a of the horizontal cylinder 6 toward the front, coaxially with the horizontal cylinder 6.
A gap is provided between the inner peripheral surface of the nozzle cylinder main body 8 b and the outer peripheral surface of the open / close pin 9.

次に、以上のように構成された押下ヘッド１を用いて内容物Ｆを吐出する方法について、図１及び図２を参照して説明する。
まず、ヘッド本体７の頂壁部１０を押下すると、横筒６の下端壁６ｂに当接されたステム２もヘッド本体７と共に下方に移動する。この際、図２に示すように、内容物Ｆがステム２内から流通孔６ｃを介して横筒６内に流入し、この内容物Ｆの液圧によってノズル筒部材８が前方に向けて押圧される。 Next, a method of discharging the contents F using the pressing head 1 configured as described above will be described with reference to FIGS.
First, when the top wall portion 10 of the head main body 7 is pressed, the stem 2 that is in contact with the lower end wall 6 b of the horizontal cylinder 6 also moves downward together with the head main body 7. At this time, as shown in FIG. 2, the content F flows into the horizontal cylinder 6 from the stem 2 through the flow hole 6c, and the nozzle cylinder member 8 is pressed forward by the hydraulic pressure of the content F. Is done.

そして、ノズル筒部材８は、コイルスプリング１８による後方付勢力に抗して、シール筒部材１７の後端部１７ａが横筒６の内周面に摺接しながら、横筒６内で前進する。これにより、ノズル筒部材８のノズル孔１５が開閉ピン９から離反し、ノズル孔１５が開口させられる。すると、横筒６及びノズル筒部材８の各内部の内容物Ｆが、ノズル孔１５から外部に吐出される。   The nozzle cylinder member 8 moves forward in the horizontal cylinder 6 while the rear end portion 17 a of the seal cylinder member 17 is in sliding contact with the inner peripheral surface of the horizontal cylinder 6 against the rear biasing force of the coil spring 18. Thereby, the nozzle hole 15 of the nozzle cylinder member 8 is separated from the opening / closing pin 9, and the nozzle hole 15 is opened. Then, the contents F inside the horizontal cylinder 6 and the nozzle cylinder member 8 are discharged from the nozzle hole 15 to the outside.

次に、ヘッド本体７の頂壁部１０に対する前述の押下を解除すると、ステム２が上昇し横筒６内へのステム２からの内容物Ｆの流入が停止される。この際、ノズル筒部材８にコイルスプリング１８による後方付勢力が作用しているので、ノズル筒部材８が横筒６内で後退させられる。これにより、ノズル筒部材８のノズル孔１５が開閉ピン９に接近し、ノズル孔１５が閉塞させられる。なお、ステム２の上昇に伴い、押下ヘッド１も上方に移動させられる。   Next, when the above-described pressing on the top wall portion 10 of the head body 7 is released, the stem 2 rises and the flow of the contents F from the stem 2 into the horizontal cylinder 6 is stopped. At this time, since the rear urging force of the coil spring 18 acts on the nozzle cylinder member 8, the nozzle cylinder member 8 is retracted in the horizontal cylinder 6. Thereby, the nozzle hole 15 of the nozzle cylinder member 8 approaches the open / close pin 9 and the nozzle hole 15 is closed. As the stem 2 is raised, the pressing head 1 is also moved upward.

以上に示したように本実施形態に係る押下ヘッド１によれば、例えば装着筒部材や梃子部材等を設けるといった従来技術のような構成としなくても、ノズル孔１５を開閉することが可能になる。従って、ノズル孔１５を開閉可能な押下ヘッド１の部品点数を低減し、構造の簡素化を図ることができる。   As described above, according to the pressing head 1 according to the present embodiment, the nozzle hole 15 can be opened and closed without using the configuration of the prior art such as providing a mounting cylinder member, a lever member, or the like. Become. Therefore, the number of parts of the pressing head 1 that can open and close the nozzle hole 15 can be reduced, and the structure can be simplified.

また、シール筒部材１７が横筒６より柔軟な材質で形成されているので、横筒６とシール筒部材１７との間の液密性を向上することができる。このため、ノズル筒部材８の外周面側を通って内容物Ｆが外部に漏出するのを抑制し、内容物Ｆを確実にノズル孔１５から吐出させることができる。   Further, since the seal cylinder member 17 is formed of a material that is more flexible than the horizontal cylinder 6, the liquid tightness between the horizontal cylinder 6 and the seal cylinder member 17 can be improved. For this reason, it can suppress that the content F leaks outside through the outer peripheral surface side of the nozzle cylinder member 8, and can discharge the content F from the nozzle hole 15 reliably.

なお、本発明の技術的範囲は上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
例えば、上記実施形態では、ノズル筒部材８を後方付勢状態とするためにコイルスプリング１８を用いているが、これに変えてノズル筒本体８ｂと一体に形成された樹脂材料からなるスプリングを用いてもよい。この場合、更なる部品点数の削減を図ることができる。 The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above embodiment, the coil spring 18 is used to place the nozzle cylinder member 8 in the rear biased state, but instead of this, a spring made of a resin material integrally formed with the nozzle cylinder body 8b is used. May be. In this case, the number of parts can be further reduced.

また、上記実施形態では、シール筒部材１７を、横筒６やノズル筒本体８ｂより柔軟な材質で形成したが、例えば横筒６やノズル筒本体８ｂと同じ材質で形成しても構わない。更にまた、シール筒部材１７は、ノズル筒本体８ｂと一体に形成されていても構わない。   Moreover, in the said embodiment, although the seal cylinder member 17 was formed with the material more flexible than the horizontal cylinder 6 or the nozzle cylinder main body 8b, you may form with the same material as the horizontal cylinder 6 or the nozzle cylinder main body 8b, for example. Furthermore, the seal cylinder member 17 may be formed integrally with the nozzle cylinder body 8b.

また、上記実施形態では、ノズル筒本体８ｂの前端部は、挿通筒部材１２から前方に突出しているものとしたが、内容物Ｆの吐出時及びヘッド本体７を押下する前の待機時の別を問わず、挿通筒部材１２から前方に突出していなくても構わない。   Further, in the above embodiment, the front end portion of the nozzle cylinder main body 8b protrudes forward from the insertion cylinder member 12. However, the nozzle cylinder main body 8b is separated from the front when the contents F are discharged and before the head main body 7 is pressed. Regardless of the case, it does not need to protrude forward from the insertion tube member 12.

その他、本発明の趣旨に逸脱しない範囲で、上記実施形態における構成要素を周知の構成要素に置き換えることは適宜可能であり、また、上記した変形例を適宜組み合わせてもよい。   In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
