Description

【0001】
【発明の属する技術分野】
本発明は、ポンプによって吸引、加圧した内容物を泡状にして噴出させるディスペンサーに用いて好適な噴射ノズルに関するものであり、該噴射ノズルとディスペンサー本体(スピンエレメント)との連結を確実にしてスプレーパターンの安定化を図ろうとするものである。
【0002】
【従来の技術】
黴び取り剤や漂白剤あるいは整髪剤等の内容物を泡状にして噴出させるディスペンサーは、レバーを牽曳して内容物を噴出させるトリガータイプや押圧ヘッドを押し込んで内容物を噴出させるプライミングタイプのものが知られている。
【0003】
上記のような従来型のディスペンサーに装着される噴射ノズルはそのタイプの如何にかかわらず、ディスペンサー本体のスピンエレメントの先端に係合する噴射チップを備えるものでその構造はほぼ共通しており、それらは、噴射チップの背面に設けられた溝部にスピンエレメントの先端を差し込むことで連結されている(例えば特許文献1、特許文献2参照)。
【0004】
【特許文献1】
特公昭62−42667号公報。
【0005】
【特許文献2】
実公昭60−27484号公報。
【0006】
ところで、従来のディスペンサーは、内容物を噴射させる際、該噴射チップの背面には高い圧力がかかるため噴射ノズルがスピンエレメントから離れるように浮き上がってその間から内容物が漏れだしスプレーパターンに影響を与えるおそれがあった。
【0007】
【発明が解決しようとする課題】
本発明の課題は、上述のような従来問題を解消できる新規な噴射ノズルを提案するところにある。
【0008】
【課題を解決するための手段】
本発明は、ディスペンサーのスピンエレメントの先端に装着され該スピンエレメントの通路につながる開孔を有する噴射チップを備えたノズルであって、
前記噴射チップに、内筒と外筒とを同心二重配置にしてその相互間に環状溝を設け、この環状溝にスピンエレメントの先端を差し込むことによってそれらを相互に連結し、この時、該環状溝の溝底部においてシール部を形成するとともに、内筒の外表面とスピンエレメントの内表面との間でシール部を形成してなることを特徴とするディスペンサー用噴射ノズルであり、このノズルは、噴射チップと造泡筒とを組み合わせて泡生成部材とすることができる。
【0009】
【発明の実施の形態】
以下、図面を参照して本発明をより具体的に説明する。
【0010】
図1、図2は本発明に従う噴射ノズルをトリガー式ディスペンサー(噴出器)に装着した実施の形態を示したものである。
【0011】
図1、2において1はディスペンサー本体内に組み込まれた噴射筒、2は噴射筒の先端に一体的に設けられたスピンエレメント、3はスピンエレメント2の通路2aにつながる開孔hを有する噴射チップ、4は噴射チップ3を内装する泡生成部材であって、この泡生成部材4と噴射チップ3とにて噴射ノズルを構成する。
【0012】
また、5は噴射チップ3の内筒3aと外筒3bを同心2重配置にしてその相互間に形成される環状溝、6はレバー、7はレバー6に係合するピストン、8はピストン7をスライド可能に保持するシリンダー、そして9は内容物を吸引する吸引管である。
【0013】
上記の構成になる噴射ノズルはスピンエレメント2を環状溝5に差し込むことによってそれらを相互に連結することができるようになっており、この時、環状溝5の溝底部においてシール部Sが、また、内筒3aの外表面とスピンエレメント2の内表面との間でシール部Sがそれぞれ形成されることとなり、噴射チップ3の背面に高い圧力がかかっても、従来型の噴射ノズルに比較して該噴射チップ3が受ける圧力面積を小さくすることができるので噴射ノズルがスピンエレメント2から簡単に浮き上がって内容物が漏れだすことはなくスプレーパターンが常に安定化される。
【0014】
本発明の実施の形態では、噴射チップ3の全体を泡生成部材4にて覆う構造を例として示したが、泡生成部材4の外壁部を取り除いて噴射チップ3の先端内でに泡生成部材4を内装する構造を採用してもよい。また、内容物を棒状にして噴出させる場合や霧状にして噴出させる場合には噴射チップ3から泡生成部材4を取り外した構造とすることもできる。
【0015】
【発明の効果】
本発明によれば、噴射チップとスピンエレメントとの相互間で2箇所のシール部を形成するようにしたので内容物を噴出させる際に噴射ノズルがスピンエレメントから浮き上がって内容物が漏れだすことがなく安定したスプレーパターンのもとでの噴出が可能になる。

BACKGROUND OF THE INVENTION
The present invention relates to an injection nozzle suitable for use in a dispenser that causes the contents sucked and pressurized by a pump to be foamed and ejected. The connection between the injection nozzle and the dispenser body (spin element) is ensured. It is intended to stabilize the spray pattern.
[0002]
[Prior art]
The dispenser that foams the contents such as wiping agent, bleach or hairstyling agent in the form of foam is a trigger type that checks the lever and ejects the contents, and a priming type that pushes the pressure head and ejects the contents Things are known.
[0003]
Regardless of the type, the injection nozzle mounted on the conventional dispenser as described above is provided with an injection tip that engages the tip of the spin element of the dispenser body, and its structure is almost the same. Are connected by inserting the tip of the spin element into a groove provided on the back surface of the injection tip (see, for example, Patent Document 1 and Patent Document 2).
[0004]
[Patent Document 1]
Japanese Examined Patent Publication No. 62-42667.
[0005]
[Patent Document 2]
Japanese Utility Model Publication No. 60-27484.
[0006]
By the way, when a conventional dispenser injects the contents, a high pressure is applied to the back surface of the injection tip, so that the injection nozzle floats away from the spin element, and the contents leak from there and affect the spray pattern. There was a fear.
[0007]
[Problems to be solved by the invention]
The subject of this invention exists in the place which proposes the novel injection nozzle which can eliminate the above conventional problems.
[0008]
[Means for Solving the Problems]
The present invention is a nozzle having an injection tip attached to the tip of a spin element of a dispenser and having an opening connected to a passage of the spin element,
The injection tip, an annular groove between its mutually by the inner cylinder and an outer cylinder concentrically double arrangement provided, interconnected them by tip pointing write Mukoto spin element in the annular groove, when the The dispenser spray nozzle is characterized in that a seal portion is formed at the groove bottom portion of the annular groove and a seal portion is formed between the outer surface of the inner cylinder and the inner surface of the spin element. A nozzle can be made into a foam production | generation member combining an injection tip and a foaming cylinder.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
[0010]
1 and 2 show an embodiment in which a spray nozzle according to the present invention is mounted on a trigger type dispenser (spouter).
[0011]
1 and 2, reference numeral 1 denotes an injection cylinder incorporated in the dispenser main body, 2 denotes a spin element integrally provided at the tip of the injection cylinder, and 3 denotes an injection tip having an opening h connected to the passage 2a of the spin element 2. Reference numeral 4 denotes a foam generating member that houses the injection tip 3, and the foam generation member 4 and the injection tip 3 constitute an injection nozzle.
[0012]
Reference numeral 5 denotes an annular groove formed between the inner cylinder 3a and the outer cylinder 3b of the injection tip 3 which are concentrically arranged, 6 is a lever, 7 is a piston engaged with the lever 6, and 8 is a piston 7 Is a slidable cylinder, and 9 is a suction tube for aspirating the contents.
[0013]
The injection nozzle configured as described above can be connected to each other by inserting the spin element 2 into the annular groove 5. At this time, the seal portion S is also provided at the groove bottom of the annular groove 5. , becomes the seal portion S 1 is formed respectively between the outer surface and the inner surface of the spin element 2 of the inner cylinder 3a, even if a higher pressure on the back of the injection tip 3, compared to conventional injection nozzle Since the pressure area received by the spray tip 3 can be reduced, the spray nozzle can be easily lifted from the spin element 2 and the contents do not leak out, so that the spray pattern is always stabilized.
[0014]
In the embodiment of the present invention, the structure in which the entire spray tip 3 is covered with the foam generating member 4 is shown as an example, but the outer wall portion of the foam generating member 4 is removed and the foam generating member is formed in the tip of the spray tip 3. 4 may be adopted. Further, when the contents are ejected in the form of a rod or in the form of a mist, the foam generating member 4 can be removed from the ejection tip 3.
[0015]
【The invention's effect】
According to the present invention, since two seal portions are formed between the spray tip and the spin element, when the contents are ejected, the spray nozzle may float from the spin element and the contents may leak out. It is possible to erupt under a stable spray pattern.
