Description

本発明は、容器内の液体を吸引、加圧、圧縮して噴出させる噴出器に用いて好適なノズルに関するものであり、液体の噴出操作で該液体を少なくとも２種類のパターンで同時に噴出させて使用感を一層明瞭にしようとするものである。   The present invention relates to a nozzle suitable for use in an ejector that ejects a liquid in a container by suction, pressurization, and compression. The liquid is ejected simultaneously in at least two patterns by a liquid ejection operation. It is intended to further clarify the feeling of use.

整髪料や育毛剤は、塗布対象物に対して広範囲にまんべんなく塗布することができるように霧状にして噴出させるのが普通であり、そのための噴霧器としては、トリガースプレーや押圧ヘッドを備えたスプレーなどこれまでに多数のものが提案されている（例えば特許文献１参照）。   Hair conditioners and hair growth agents are usually sprayed in the form of a mist so that they can be applied evenly over a wide range of objects to be applied. So far, many have been proposed (see, for example, Patent Document 1).

特公昭６０−３２５０５号公報Japanese Patent Publication No. 60-32505

ところで、頭皮に直接液体を吹きつける育毛剤のような液体を対象とするものにおいては、該液体を霧状にして噴出させた場合に、それが降りかかっているかどうか明瞭ではなく、使用感が得られにくいところに問題を残していた。   By the way, in the case of liquids such as a hair-growth agent that sprays liquid directly on the scalp, it is not clear whether or not the liquid is sprayed when sprayed in the form of a mist. It left a problem where it was difficult to obtain.

本発明の課題は、噴出させた液体が降りかかっていることを明瞭に把握できる新規な噴出ノズルを提案するところにある。   The subject of this invention exists in the place which proposes the novel ejection nozzle which can grasp | ascertain clearly that the ejected liquid is falling.

本発明は、液体の噴出経路を有するノズル本体と、このノズル本体の噴出経路の出側端に装着され該噴出経路を通して送給された液体を外界へ向けて噴出させるチップとからなる噴出ノズルであって、
前記チップは、霧状とストリーム状、あるいは水滴状とストリーム状の少なくとも２種類の噴出パターンにて液体を同時に噴出させる異なる噴出開孔を有することを特徴とする噴出ノズルである。 The present invention is an ejection nozzle comprising a nozzle body having a liquid ejection path, and a tip that is mounted on the exit end of the ejection path of the nozzle body and ejects liquid fed through the ejection path toward the outside. There,
The tip is an ejection nozzle characterized by having different ejection openings for ejecting liquid simultaneously in at least two types of ejection patterns of mist and stream, or water droplet and stream.

液体の噴出パターンのうちの１つをピンポイントにて衝突させることができるストリーム状にすることで、噴出衝撃が伝わり、液体が降りかかっているかどうか明瞭になり、使用感が得られる。   By making one of the liquid ejection patterns into a stream shape that can be collided at a pinpoint, the ejection impact is transmitted, and it becomes clear whether the liquid is falling, and a feeling of use is obtained.

以下、図面を用いて本発明をより具体的に説明する。
図１は本発明にしたがう噴出ノズルを備えた液体噴出器の断面を示したものであり、図２は液体の噴出状況を示した図である。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows a cross-section of a liquid ejector equipped with an ejection nozzle according to the present invention, and FIG. 2 shows the state of liquid ejection.

図における１は押圧ヘッドとして使用されるノズル本体である。このノズル本体１は液体の噴出経路１ａを有しており、その天面を押圧して上下に繰返し往復移動させることで液体の噴出を可能とする。   In the figure, reference numeral 1 denotes a nozzle body used as a pressing head. The nozzle body 1 has a liquid ejection path 1a, and the top surface is pressed and reciprocated up and down to allow liquid ejection.

また、２はノズル本体１の噴出経路１ａの出側端にアンダーカット嵌合により装着されたチップである。このチップ２はその背面を図３に示すように、スピン通路２ａを経て霧状に噴出させる噴出開孔２ｂと、ストリーム状に噴出させる噴出開孔２ｃとを備えている。   Reference numeral 2 denotes a tip attached to the outlet end of the ejection path 1a of the nozzle body 1 by undercut fitting. As shown in FIG. 3, the chip 2 is provided with an ejection hole 2b that ejects in the form of a mist through the spin passage 2a, and an ejection opening 2c that ejects the stream in the form of a stream.

２種類の噴出開孔２ｂ、２ｃを有するノズルにて液体を異なるパターンで同時に噴出させると、図２に示すようにストリーム状に噴出させたところが局所的に強く衝突することになり、これにより液体が降りかかっているかどうか明瞭に把握できることになる（使用感が得られる）。   When liquids are simultaneously ejected in different patterns using nozzles having two types of ejection openings 2b and 2c, the portions ejected in a stream form as shown in FIG. It is possible to clearly understand whether or not it is falling (you can get a feeling of use).

上掲図１に示した噴出ノズルは噴出開孔２ｂ、２ｃの何れもが、単一の噴出経路１ａを通して液体を供給する構成のものを例として示しているが、図４に他の実施の形態を示す如く、チップ２とノズル本体１の相互間に別途に通路３を設けてそれぞれの噴出開孔２ｂ、２ｃから液体を噴出させてもよい。なお、本実施例では、スピン通路２ａをチップ２の背面に形成したが、これに限るものではなく、チップ２には噴出開孔２ｂのみとしてスピン通路２ａをチップ２の背面に当接するノズル本体１に形成することもできる。   The jet nozzle shown in FIG. 1 shows an example in which both of the jet openings 2b and 2c supply liquid through a single jet passage 1a, but FIG. 4 shows another embodiment. As shown in the embodiment, a separate passage 3 may be provided between the tip 2 and the nozzle body 1 to eject the liquid from the respective ejection openings 2b and 2c. In this embodiment, the spin passage 2a is formed on the back surface of the chip 2. However, the present invention is not limited to this. 1 can also be formed.

図５、図６は本発明にしたがう噴出ノズルのさらに他の実施の形態を示したものである。ここに示した噴出ノズルは、チップ２の中央に位置する噴出開孔２ｂからはストリーム状のパターンで液体を噴出させ、噴出開孔２ｂを取り囲む円周上に等間隔に１２個の噴出開孔２ｃを設け、その噴出開孔２ｃのそれぞれから水滴状のパターンで噴出させるのに適した構造のものである。   5 and 6 show still another embodiment of the ejection nozzle according to the present invention. The ejection nozzle shown here ejects liquid in a stream-like pattern from the ejection aperture 2b located in the center of the chip 2, and 12 ejection apertures are equally spaced on the circumference surrounding the ejection aperture 2b. 2c is provided, and has a structure suitable for being ejected from each of the ejection openings 2c in a water droplet pattern.

かかる噴出ノズルにおいても、噴出開孔２ｂから噴出させたストリーム状のパターンのほうが局所的に強く衝突することとなり使用感が明瞭になる。   Also in such an ejection nozzle, the stream-like pattern ejected from the ejection opening 2b locally collides more strongly, and the usability becomes clear.

噴出パターンについて本発明の実施の形態では、霧状とストリーム状のパタ―ン、あるいはストリーム状と水滴状のパターンの組合せについて示したが、噴出パターンは用途等に応じて種々変更できるものであり、実施例のものには限定されない。また、噴出開孔の形状や数も適宜に変更可能であり、この点についての制約もない。   Regarding the ejection pattern In the embodiment of the present invention, the mist and stream patterns, or the combination of the stream and water droplet patterns are shown. However, the ejection pattern can be variously changed according to the application. However, the present invention is not limited to the examples. Further, the shape and number of the ejection openings can be changed as appropriate, and there is no restriction on this point.

噴出された液体が所望の領域に降りかかっているかどうかを明瞭に把握できる噴出ノズルが提供できる。   An ejection nozzle that can clearly grasp whether or not the ejected liquid is falling on a desired region can be provided.
