Description

【０００１】
【産業上の利用分野】
本発明は、エアゾール缶用のバルブ装置に関し、特に内部圧力の昇圧のために液状の内容物とは別に炭酸ガスなどによる圧力ガスを圧力充填されるエアゾール缶用のバルブ装置に関するものである。
【０００２】
【従来の技術】
エアゾール缶用のバルブ装置は、一般に、弁体、弁座部を内蔵したバルブ本体より垂下された合成樹脂などによる可撓性のディップチューブを有し、ディップチューブの先端に重り部材を装着され、重り部材の底面（先端面）にディップチューブの先端ポートを開口されている。このバルブ装置はバルブ本体に一体接続されたマウンテンキャップと共にエアゾール缶の口部にかしめ結合されることによりエアゾール缶を密閉する。この装着状態下においては、先端ポートは重り部材と共にエアゾール缶の底部近傍にて缶内の内容物中に浸漬される。
【０００３】
エアゾール缶には、内部圧力を昇圧するために、液状の内容物とは別に炭酸ガスなどが圧力充填されるものがあり、この炭酸ガスの圧力充填は、エアゾール缶に内容物を充填したのちに、エアゾール缶にかしめ結合されたバルブ装置より行われる。
バルブ装置よりの炭酸ガスの圧力充填時には、そのガス充填によってエアゾール缶の内圧が急上昇して規定圧力以上になることを回避するために、炭酸ガスを内容物である液中に溶かすことによって圧力上昇を抑制しながら行う必要がある。このことに対して炭酸ガスはディップチューブの先端ポートより内容物中に噴出するから、炭酸ガスは、ある程度、内容物中に溶けるが、しかし充分ではないことが多い。このため従来は、エアゾール缶を外部より揺らして内容物を撹拌することにより、炭酸ガスが内容物に溶け易いようにしている。
【０００４】
【発明が解決しようとする課題】
しかしながら、この場合には、エアゾール缶を外部より揺らすための装置が別途必要となり、炭酸ガスの圧力充填装置、充填ラインの構造が複雑なものになる。
本発明は、上述の如き問題点に着目してなされたものであり、エアゾール缶を外部より揺らす装置を必要とすることなく、内容物を撹拌した状態にて炭酸ガスなどの圧力ガスをエアゾール缶内に良好に圧力充填できるように改良されたエアゾール缶用のバルブ装置を提供することを目的としている。
【０００５】
【課題を解決するための手段】
上述の目的を達成するため、本発明によるエアゾール缶用のバルブ装置は、バルブ本体より垂下された可撓性のディップチューブの先端に重り部材を装着され、前記重り部材に前記ディップチューブの先端ポートが開口形成されているエアゾール缶用のバルブ装置において、前記先端ポートが前記重り部材に前記ディップチューブの径方向と同方向に延在して設けられた横孔により前記重り部材の側面に開口していることを特徴としている。
【０００６】
【作 用】
上述の構成によれば、バルブ装置よりエアゾール缶内に炭酸ガスなどの圧力ガスが圧力充填されると、その圧力ガスは重り部材の側面に開口した先端ポートより噴出されるから、その反力によって重り部材が、ディップチューブより吊り下げられてエアゾール缶内の内容物中に浸漬された状態で、横方向に振り回されるようにして激しく動くようになる。これにより内容物がかき回され、エアゾール缶を外部より揺らすことなく撹拌効果が得られ、炭酸ガスなどの圧力ガスが内容物に溶け易いようになり、所要の圧力ガスの圧力充填が良好に行われるようになる。
【０００７】
【実施例】
以下に添付の図を参照して本発明を実施例について詳細に説明する。
図１は本発明によるバルブ装置を取り付けられたエアゾール缶の一実施例を示している。図１において、１は圧力構造体によるエアゾール缶を、３はバルブ装置を各々示している。
【０００８】
バルブ装置３はバルブ本体５と一体接続されているマウンテンキャップ７をもってエアゾール缶１の口部９にかしめ結合され、シール部材１１と共にエアゾール缶１を密閉容器とする。バルブ本体５は、内部に弁体、弁座部、ばねなどを内蔵し、ステム１３を押し下げられることにより開弁する一般的構造のものである。
【０００９】
バルブ本体５のポート１５には合成樹脂などによる可撓性のディップチューブ１７の一端がはめ込み式に連通接続されている。ディップチューブ１７は、バルブ本体５より垂下され、エアゾール缶１の底部に位置する先端に重り部材１９が装着されている。重り部材１９は盲孔２１にディップチューブ１７を挿入されており、盲孔２１と重り部材１９の外側面との間にディップチューブ１７の径方向と同方向に延在した横孔２３による先端ポート２５が重り部材１９の側面に開口している。これによりディップチューブ１７は側方開口の先端ポート２５のみをもってエアゾール缶１内に連通する。
【００１０】
エアゾール缶１に対する炭酸ガスの圧力充填は、エアゾール缶１に内容物を装填したのちに、エアゾール缶１にかしめ結合されたバルブ装置３のステム１３より逆流式に行われる。
バルブ装置３よりエアゾール缶１内に炭酸ガスが圧力充填されると、その炭酸ガスは重り部材１９の側面に開口している先端ポート２５より噴出されるから、その噴射反力がディップチューブ１７の径方向の力（推力）として重り部材１９に作用する。このため重り部材１９は、ディップチューブ１７より吊り下げられてエアゾール缶１内の内容物中に浸漬された状態で、ディップチューブ１７と共に横方向に振り回されるようにして激しく動くようになる。
【００１１】
これによりエアゾール缶１内に内容物がかき回され、エアゾール缶１を外部より揺らすことなく撹拌効果が得られ、炭酸ガスが内容物に溶け易いようになり、エアゾール缶１の内圧が急上昇することが回避され、所要の炭酸ガスの圧力充填が良好に行われるようになる。
なお、炭酸ガスを２５ｋｇｆ／ｃｍ2 程度の圧力をもって圧力充填する場合には、先端ポート２５の口径は０．４〜１．０ｍｍ程度であればよい。また先端ポート２５の形状は円形の限定されることはなく、スリット状であってよい。
【００１２】
表１は、水／アルコール混合物を収容した容器に対して炭酸ガスを充填し、同じ平衡圧力を得る場合の実験結果を示している。実験は、異なった水／アルコール比率の内容物を収容した容器に対して、本発明のエアゾール缶用のバルブ装置により炭酸ガスを充填する場合（横方向）と、比較例として従来のバルブ装置により充填する場合（下方）との双方で行った。表から明らかなように、本発明のエアゾール缶用のバルブ装置により炭酸ガスを充填する場合には、初期圧力値が低い値で所定の平衡圧力を得ることができ、本発明のバルブ装置の優位性が立証されている。

【発明の効果】
以上の説明から理解される如く、本発明によるエアゾール缶用のバルブ装置によれば、バルブ装置よりエアゾール缶内に炭酸ガスなどの圧力ガスが圧力充填されると、その圧力ガスは重り部材の側面に開口した先端ポートより噴出され、その反力によって重り部材がエアゾール缶内の内容物中に浸漬された状態で、横方向に振り回されるようにして激しく動くようになるから、内容物がかき回され、エアゾール缶を外部より揺らすことなく撹拌効果が得られ、炭酸ガスなどの圧力ガスが内容物に溶け易いようになり、所要の圧力ガスの圧力充填が良好に行われるようになる。これによりエアゾール缶を外部より揺らす装置が不要になり、炭酸ガスの圧力充填装置、充填ラインの構造が簡素化される。

[Industrial application fields]
The present invention relates to a valve device for an aerosol can, and more particularly, to a valve device for an aerosol can that is filled with a pressure gas such as carbon dioxide gas in addition to a liquid content in order to increase the internal pressure.
[0002]
[Prior art]
A valve device for an aerosol can generally has a flexible dip tube made of synthetic resin or the like suspended from a valve body incorporating a valve body and a valve seat, and a weight member is attached to the tip of the dip tube. The tip port of the dip tube is opened on the bottom surface (tip surface) of the weight member. This valve device seals the aerosol can by being caulked to the mouth of the aerosol can together with a mountain cap integrally connected to the valve body. Under this mounted state, the tip port is immersed in the contents of the can near the bottom of the aerosol can together with the weight member.
[0003]
Some aerosol cans are pressure-filled with carbon dioxide gas in addition to the liquid contents in order to increase the internal pressure. This pressure filling with carbon dioxide gas is performed after filling the aerosol cans with the contents. And a valve device that is caulked to an aerosol can.
When filling the pressure of carbon dioxide from the valve device, the pressure rises by dissolving the carbon dioxide in the liquid, which is the contents, in order to avoid the internal pressure of the aerosol can rising rapidly due to the gas filling and exceeding the specified pressure. It is necessary to do this while restraining. On the other hand, carbon dioxide gas jets into the contents from the tip port of the dip tube, so that the carbon dioxide gas is dissolved to some extent in the contents, but is often not sufficient. For this reason, conventionally, by stirring the contents by shaking the aerosol can from the outside, the carbon dioxide gas is easily dissolved in the contents.
[0004]
[Problems to be solved by the invention]
However, in this case, a separate device for shaking the aerosol can from the outside is required, and the structure of the carbon dioxide pressure filling device and the filling line becomes complicated.
The present invention has been made paying attention to the problems as described above, and does not require a device that shakes the aerosol can from the outside, and pressure gas such as carbon dioxide gas can be applied to the aerosol can while stirring the contents. It is an object of the present invention to provide a valve device for an aerosol can which is improved so that it can be pressure-filled inside.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a valve device for an aerosol can according to the present invention has a weight member attached to the tip of a flexible dip tube suspended from the valve body, and the weight member has a tip port of the dip tube. In the valve device for an aerosol can in which the opening is formed, the distal end port is opened on a side surface of the weight member by a lateral hole provided in the weight member so as to extend in the same direction as the radial direction of the dip tube. It is characterized by having.
[0006]
[Operation]
According to the above-described configuration, when pressure gas such as carbon dioxide gas is pressure-filled into the aerosol can from the valve device, the pressure gas is ejected from the tip port opened on the side surface of the weight member. When the weight member is suspended from the dip tube and immersed in the contents in the aerosol can, the weight member moves vigorously as if it is swung in the lateral direction. As a result, the contents are stirred, a stirring effect is obtained without shaking the aerosol can from the outside, pressure gas such as carbon dioxide gas is easily dissolved in the contents, and pressure filling with the required pressure gas is performed well. It becomes like this.
[0007]
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows an embodiment of an aerosol can fitted with a valve device according to the present invention. In FIG. 1, 1 shows an aerosol can by a pressure structure, and 3 shows a valve device.
[0008]
The valve device 3 is caulked and joined to the mouth 9 of the aerosol can 1 with a mountain cap 7 integrally connected to the valve body 5, and the aerosol can 1 is used as a sealed container together with the seal member 11. The valve main body 5 has a general structure in which a valve body, a valve seat portion, a spring and the like are built in and opened when the stem 13 is pushed down.
[0009]
One end of a flexible dip tube 17 made of synthetic resin or the like is connected to the port 15 of the valve body 5 in a fitting manner. The dip tube 17 is suspended from the valve main body 5, and a weight member 19 is attached to the tip located at the bottom of the aerosol can 1. The weight member 19 has a dip tube 17 inserted into the blind hole 21, and a distal end port formed by a lateral hole 23 extending in the same direction as the radial direction of the dip tube 17 between the blind hole 21 and the outer surface of the weight member 19. 25 is open to the side surface of the weight member 19. As a result, the dip tube 17 communicates with the inside of the aerosol can 1 with only the tip port 25 having a side opening.
[0010]
The pressure filling of the carbon dioxide gas into the aerosol can 1 is performed in a reverse flow manner from the stem 13 of the valve device 3 that is caulked and coupled to the aerosol can 1 after the contents are loaded into the aerosol can 1.
When carbon dioxide gas is pressure-filled into the aerosol can 1 from the valve device 3, the carbon dioxide gas is ejected from the distal end port 25 opened on the side surface of the weight member 19. It acts on the weight member 19 as a radial force (thrust). For this reason, the weight member 19 hangs from the dip tube 17 and is vigorously moved while being swung in the horizontal direction together with the dip tube 17 while being immersed in the contents in the aerosol can 1.
[0011]
As a result, the contents are stirred in the aerosol can 1, a stirring effect is obtained without shaking the aerosol can 1 from the outside, carbon dioxide gas is easily dissolved in the contents, and the internal pressure of the aerosol can 1 rises rapidly. This avoids the required pressure filling of carbon dioxide gas.
When carbon dioxide is pressure-filled with a pressure of about 25 kgf / cm 2 , the diameter of the tip port 25 may be about 0.4 to 1.0 mm. The shape of the distal end port 25 is not limited to a circular shape, and may be a slit shape.
[0012]
Table 1 shows experimental results when a container containing a water / alcohol mixture is filled with carbon dioxide gas to obtain the same equilibrium pressure. In the experiment, a container containing contents with different water / alcohol ratios was filled with carbon dioxide gas by the valve device for an aerosol can of the present invention (in the horizontal direction), and a conventional valve device was used as a comparative example. This was done both when filling (downward). As is apparent from the table, when carbon dioxide gas is filled by the valve device for an aerosol can of the present invention, a predetermined equilibrium pressure can be obtained with a low initial pressure value, and the superiority of the valve device of the present invention. Sex has been proven.

【The invention's effect】
As can be understood from the above description, according to the valve device for an aerosol can according to the present invention, when pressure gas such as carbon dioxide gas is pressure-filled into the aerosol can from the valve device, the pressure gas is applied to the side surface of the weight member. Since the weight member is immersed in the contents in the aerosol can by the reaction force, it moves vigorously as if it is swung laterally, and the contents are stirred. The stirring effect can be obtained without shaking the aerosol can from the outside, and the pressure gas such as carbon dioxide gas can be easily dissolved in the contents, and the pressure filling of the required pressure gas can be satisfactorily performed. This eliminates the need for a device for shaking the aerosol can from the outside and simplifies the structure of the carbon dioxide pressure filling device and filling line.
