を汚染することがないエアゾール缶用注出装置に関する
。Detailed Description of the Invention (Industrial Application Field) The present invention can prevent the contents from dripping that occurs immediately or within a short period of time after ejecting the contents from an aerosol can, and does not contaminate the nozzle. This invention relates to a dispensing device for aerosol cans.
（従来の技術及び解決しようとする課、Ｉ！ｉ）エアゾ
ール缶用注出装置（通称、スパウトと称される）は、ス
パウトの操作部を押すことにより。(Prior art and the section to be solved, I!i) A dispensing device for an aerosol can (commonly called a spout) is used by pressing the operating part of the spout.
バルブのステムを押し、バルブを開口して内容物を注出
する構造になっている。The structure is such that the valve stem is pressed to open the valve and pour out the contents.
しかし、スパウトの操作部の押圧を止めるとノズルの下
に位置するバルブが閉じるため、スパウト内に内容物が
残るが、その内容物にはガスが含有しているため体積が
膨張し、ノズル先端から液が膨出し、液だれ現象を起こ
す。粘度の比較的高い内容物の場合は液ぎれが悪いため
、−層着しい現象となる。液だれかあるとノズルや缶を
汚してきたならしい。However, when the pressure on the operating part of the spout is stopped, the valve located below the nozzle closes, and the contents remain inside the spout, but because the contents contain gas, the volume expands, and the tip of the nozzle The liquid swells out, causing a dripping phenomenon. If the content is relatively high in viscosity, the liquid will not run out easily, resulting in a phenomenon of layering. It seems that if there was any liquid, it would have contaminated the nozzle and can.
そのため、スパウトの先端部にバルブ機構を設け、２つ
のバルブで液だれを防止する方法が行われているが、ス
テム側のバルブが先に閉じる構造であるため、先端バル
ブの先に液が膨出し、依然として液だれを起こしてしま
い、完全に防ぐことはできない。For this reason, a method is used to prevent liquid dripping by installing a valve mechanism at the tip of the spout and using two valves, but since the valve on the stem side closes first, the liquid expands beyond the tip valve. However, it still causes dripping, which cannot be completely prevented.
また、他の液だれ防止機構として、実開昭６２−５８４

プ内の空気室に収容する機構がある。In addition, as another drip prevention mechanism,
As shown in No. 7, an inlet is provided above the nozzle body, and a pump with a presser is fixed in a sealed state above the inlet and the presser is pressed to open the air chamber inside the pump. At the same time as shrinking, open the valve and release the pressure on the presser foot (
There is a mechanism for storing a portion of the contents in the nozzle into the air chamber in the pump (after the valve is operated).
しかし、このような機構では、以下のような問題乃至制
約がある。However, such a mechanism has the following problems or limitations.
（１）ノズルが横向きのものにしか適用できず、上方向
に内容物を噴出させるスパウトには適用できない。(1) It can only be applied to a nozzle that is oriented horizontally, and cannot be applied to a spout that spouts the contents upward.
（２）押え部をポンプにしているため、デザイン面で制
約を受ける。(2) Since the presser foot is a pump, there are restrictions in terms of design.
（３）ノズル通路の側面部にポンプを設けているため、
構造が複雑になり、構成部品数が多くなると共にコスト
高となる。(3) Since the pump is installed on the side of the nozzle passage,
The structure becomes complicated, the number of component parts increases, and the cost increases.
（４）ノズルより上部のポンプ側に液が溜るため、操作
直後に一旦引かれた液が自重で降りてきてノズルから液
だれし、完全な液だれ防止ができない。(4) Since liquid accumulates on the pump side above the nozzle, the liquid that has been drawn down immediately after operation comes down under its own weight and drips from the nozzle, making it impossible to completely prevent dripping.
本発明は、上記従来技術の欠点を解消し、簡単な機構に
より液だれを完全に防止し得るエアゾール缶用注出装置

When the valve is not operated, the volume inside the nozzle is at its maximum,
A liquid dripping device characterized in that by arranging a volume variable mechanism that minimizes the volume when the valve is operated, liquid remaining on the tip of the spout nozzle is drawn back into the spout by increasing the volume after the valve operation. The present invention summarizes a dispensing device for aerosol cans with a prevention function.
以下に本発明を更に詳細に説明する。The present invention will be explained in more detail below.
（作用）
第１図は従来のスパウト機構を示したもので、エアゾー
ル缶１の上部にスパウト４がクリンチ部２を介して装着
されており、これにオーバーキャップ３が取外し可能に
被着されている。スパウト４は、先端にスパウト注出口
５Ｌを有するノズル部５と、バルブ部６と押部７を有し
、バルブ部６のステム８に設けられた通液路とノズル部
５に設けられた通液路とがそれぞれ同一線上になるよう
に配置されている。(Function) Fig. 1 shows a conventional spout mechanism, in which a spout 4 is attached to the top of an aerosol can 1 via a clinch part 2, and an overcap 3 is removably attached to this. There is. The spout 4 has a nozzle part 5 having a spout spout 5L at the tip, a valve part 6 and a push part 7, and has a liquid passage provided in a stem 8 of the valve part 6 and a passage provided in the nozzle part 5. The liquid passages are arranged so as to be on the same line.
まず、スパウト４の押部７を押すことにより、バルブ部
６が開口し、ステム８及びノズル部５を通じ、スパウト
注出口５□から内容物を噴出する。First, by pushing the pushing part 7 of the spout 4, the valve part 6 opens and the contents are spouted from the spout outlet 5□ through the stem 8 and the nozzle part 5.
押すのをやめるとバルブ６が閉鎖し、液の注出は止まる
が、液の中に残存するガスのためバルブは閉鎖してもノ
ズル部５内の内容物が膨張し、ノズルの先端に浮き出し
、液だれ現象を起こす。ノズル径を細くしてノズル部５
内の体積を少なくすれば、その分液だれ量は少なくなる
が、液だれは止まらないし、噴出量、状態が悪くなる。When you stop pushing, the valve 6 closes and the liquid stops pouring out, but due to gas remaining in the liquid, the contents inside the nozzle part 5 expand even when the valve is closed, and float to the tip of the nozzle. , causing a dripping phenomenon. Nozzle part 5 by reducing the nozzle diameter
If the internal volume is reduced, the amount of liquid dripping will be reduced, but the dripping will not stop and the amount and condition of the spray will worsen.
一方、本発明による液だれ防止機構は、エアゾール缶用
注出装置において、スパウトのバルブ操作部を押圧し、
エアゾールのバルブ部を開口して。On the other hand, the drip prevention mechanism according to the present invention presses the valve operation part of the spout in an aerosol can dispensing device,
Open the aerosol valve.
スパウトのノズル先端から内容物を噴出する時に、この
スパウトノズルの下部とバルブステム先端との間に、バ
ルブ操作をしない時にノズル内の容積が最大となり、バ
ルブ操作時に最小になるような容積可変機構を備えたス
パウト構造であり、少なくとも容積可変可動部を備えて
いる。When spouting the contents from the nozzle tip of the spout, there is a volume variable mechanism between the lower part of the spout nozzle and the tip of the valve stem that maximizes the volume inside the nozzle when the valve is not operated and minimizes it when the valve is operated. The spout structure is equipped with at least a variable volume movable part.
したがって、ノズル先端から噴出させた後でバルブを閉
じると、ノズル部内の内容積が大きくなる構造であるの
で、ノズル部内に内容物を収めてしまうものであるから
、液だれを起こす内容物がノズル先端からはみ出すこと
がなく、完全に液だれを起こさなくすることができる。Therefore, when the valve is closed after ejecting from the tip of the nozzle, the internal volume inside the nozzle section is structured to increase, so the contents will be contained within the nozzle section, so the contents that cause dripping will be transferred to the nozzle. It does not protrude from the tip and completely prevents dripping.
このような容積可変機構としては、後述の実施例に示す
杯状のアダプターが適しているが、これのみに限定され
ないことは云うまでもない。要は。As such a volume variable mechanism, a cup-shaped adapter shown in an embodiment described later is suitable, but it goes without saying that the mechanism is not limited to this. The point is.
バルブ操作時に容積が最小となり、バルブ操作後に容積
が最大となる形状であればよい。なお、容積が最大にな
る時に、スパウトノズルの通液孔に連通ずる空間が容積
可変機構の可動部周囲の空間と連通しない機構であるこ
とが必要である。若干の連通は許容できるものの、連通
量が大きくなると、容積可変機構の容積が最大になって
も内容物を引き戻す効果が少なくなり、液だれ防止効果
が減殺されるので好ましくない。Any shape may be used as long as it has a minimum volume when the valve is operated and a maximum volume after the valve is operated. In addition, it is necessary that the space communicating with the liquid passage hole of the spout nozzle does not communicate with the space around the movable part of the volume variable mechanism when the volume is maximized. Although some communication is acceptable, if the amount of communication becomes large, the effect of pulling back the contents will decrease even if the volume of the volume variable mechanism is maximized, and the drip prevention effect will be diminished, which is not preferable.
アダプターの形状、材質は、内容物の粘度等の性状に応
じ、操作性に適合する構造が良い。The shape and material of the adapter should be selected according to the properties such as the viscosity of the contents, and should be suitable for ease of operation.
また、アダプターの材質は操作時に抵抗が少なく、操作
終了と同時に復元する必要があるため、最も適した硬さ
、弾性体が必要であり、ＬＤＰＥ、ＥＶＡ−ＥＥＡ、Ｅ
ＰＲ、ポリブタジェン等、熱可塑性弾性ポリマーが適し
ている。すなわち、アダプターは射出成形により成形す
る場合、射出成形の可能な弾性ポリマーが適している。In addition, since the material of the adapter has low resistance during operation and needs to be restored as soon as the operation is completed, the most suitable hardness and elastic material is required, such as LDPE, EVA-EEA, EVA-EEA, etc.
Thermoplastic elastic polymers such as PR, polybutadiene, etc. are suitable. That is, when the adapter is molded by injection molding, an elastic polymer that can be injection molded is suitable.
（実施例） 次に本発明を実施例により具体的に説明する。(Example) Next, the present invention will be specifically explained using examples.

形成されており、これらの平坦面５□と垂直壁５．とに
よって形成される空間内で、杯状アダプター９が容積可
変可能に配置されでいる。On the other hand, a flat surface 5□ is formed around the liquid passage in the lower part of the nozzle portion 5, and vertical walls 53 are formed at both ends of this flat surface 5□. A cup-shaped adapter 9 is disposed within the space formed by the cap and the cup-shaped adapter 9 so as to be able to vary its volume.
したがって、このアダプター９は、スパウト押圧部７を
操作し押圧している間は杯状可変部が変形して偏平状態

いる。アダプターの材質はＥＶＡを用いた。スパウトは
ＰＰ製とした。Therefore, in this adapter 9, while operating and pressing the spout pressing part 7, the cup-shaped variable part deforms and becomes flat, and the gap 10 between it and the lower part of the nozzle is almost eliminated.
When the pressing operation is stopped, the shape of the adapter 9 is restored to its original shape, and the gap 10 is also restored to its original volume. EVA was used as the material of the adapter. The spout was made of PP.

、液だれは全く起きなかった（第４図（ｃ）参照）。First, turn the aerosol can down (see Figure 4 (a)),
When the press part 7 of the spout is pressed, the valve part 6 of the aerosol can opens, and concentrated coffee is ejected from the spout spout 5 through the stem 8 and inside the nozzle (Fig. 4(b)).
reference). After spouting a predetermined amount of concentrated coffee (for about 3 seconds), when the operation was stopped, the concentrated coffee was sucked into the nozzle, and no dripping occurred (see Fig. 4(c)).
