【発明の詳細な説明】 ＜産業上の利用分野＞ この発明はエアゾール容器内の液の吸い上げに使用する
ディップチューブに関する。TECHNICAL FIELD The present invention relates to a dip tube used for sucking up a liquid in an aerosol container.
＜従来技術とその問題点＞ エアゾール容器には液を吸い上げる通称ディップチュー
ブと呼ばれる吸液管を設けてある。<Prior art and its problems> The aerosol container is provided with a liquid suction tube commonly called a dip tube for sucking up the liquid.
ところでエアゾール容器は傾けたり逆さにして使用する
ことがあるが、容器内の残液が少ないときに液を吸い上
げるためには、チューブが撓んで吸込口が常に残液へ垂
れ下がるようにしなければならない。By the way, the aerosol container may be used by tilting or upside down, but in order to suck up the liquid when the residual liquid in the container is small, it is necessary to bend the tube so that the suction port always hangs down to the residual liquid.
この要求を満たすべくチューブの吸込口に錘りを取付け
ているが、それでも充分ではなく、残液を完全に吸い上
げることはできなかった。A weight is attached to the suction port of the tube in order to meet this requirement, but this is not enough and the residual liquid could not be completely sucked up.
残液を完全に吸い上げるようにするためにはチューブを
薄肉の可撓性のあるものにすればよいわけであるが、チ
ューブの基端部は、エアゾール容器の噴霧ノズルに接続
した弁体の液取入口であるスピゴットに固嵌せねばなら
ないので、チューブはかなり嵌合性強度のあるものに構
成せねばならない。In order to completely suck up the residual liquid, the tube should be thin and flexible, but the base end of the tube is the liquid of the valve body connected to the spray nozzle of the aerosol container. The tube must be constructed to be fairly fit, as it must fit tightly into the inlet spigot.
嵌合性強度のあるチューブにするにはチューブを厚肉の
ものに成形すればよいわけであるが、厚肉にすれば可撓
性が乏しくなり、嵌合性強度を高めることと柔軟性にす
ぐれた可撓性を付与することとは二律背反的事項で、両
者を充分に満足せしめ得るチューブの製造は殆ど不可能
か至難である。To make a tube that has a good fitting strength, it is sufficient to mold the tube into a thick wall, but if you make it thick, the flexibility will be poor, and the fitting strength will be increased and flexibility will be improved. Providing excellent flexibility is a trade-off, and it is almost impossible or difficult to manufacture a tube that can satisfy both requirements.
＜本発明の目的＞ 本発明は噴霧ノズル弁体の前記スピゴットにタイトに嵌
合できて脱落を防止できる嵌合強度を有し、それでいて
可撓性にすぐれていて、吸込口が常に容器内液に臨み、
液が残らないよう完全に容器内液を噴霧できるディップ
チューブを提供できるようにした。<Purpose of the present invention> The present invention has a fitting strength capable of tightly fitting the spigot of the spray nozzle valve body and preventing the spigot from falling off, yet has excellent flexibility, and the suction port is always the liquid in the container. To the
It was made possible to provide a dip tube capable of completely spraying the liquid in the container so that no liquid remains.
＜本発明の手段＞ 上記目的を達成するために、本発明に係るディップチュ

に蛇腹部を形成し、次いで前記蛇腹部をチューブの軸線
方向で圧縮せしめること、 を特徴とする。<Means of the present invention> In order to achieve the above object, a method for manufacturing a dip tube according to the present invention is a method of forming a tube made of a synthetic resin having a thickness having an appropriate fitting strength and then fitting the tube. A thin-walled flexible portion is formed by heating and stretching on a portion excluding the combined base end portion, a bellows portion is formed on the thin-walled flexible portion, and then the bellows portion is compressed in the axial direction of the tube.
＜実施例＞ 次ぎに本発明に係るディップチューブの製造方法の一例
を添付図面に示す一具体例により説明する。<Example> Next, an example of a method for producing a dip tube according to the present invention will be described with reference to a specific example shown in the accompanying drawings.
第１図は本発明方法を実施するための材料たる合成樹脂
性のチューブで、全体に肉を厚く形成して強度の大なる
ものとしてある。FIG. 1 shows a synthetic resin tube which is a material for carrying out the method of the present invention, and has a thick wall to increase the strength.
この厚肉チューブ１における嵌合用基端部1aを除く蛇腹
形成用部1bを、図示を省略した加熱・延伸装置により加
熱、引張せしめて第２図のごとく軸線方向に延伸させら
れた薄肉部２を形成する。The thin portion 2 of the thick-walled tube 1 excluding the fitting base end portion 1a is heated and stretched by a heating / stretching device (not shown) and stretched in the axial direction as shown in FIG. To form.
次いでチューブの前記薄肉部２に図示を省略した成形型
により第３図のごとく蛇腹３を形成せしめる。Next, the bellows 3 is formed on the thin portion 2 of the tube by a molding die (not shown) as shown in FIG.
さらに、蛇腹部３をチューブの軸線方向で加圧して圧縮
蛇腹部３′に形成する。Further, the bellows portion 3 is pressed in the axial direction of the tube to form a compression bellows portion 3 '.
この実施例の方法により製造されたディップチューブ
は、チューブ本体１における嵌合用基端部は厚肉にして
嵌合強度が大となっているので、エアゾール容器の噴霧
ノズル用弁体の液取入口たるスピゴットへ脱落すること
のないようタイトに嵌合できる。The dip tube manufactured by the method of this embodiment has a thick fitting base end portion in the tube body 1 to have a large fitting strength, and therefore, the liquid intake port of the valve element for the spray nozzle of the aerosol container. It can be fitted tightly so that it will not fall into the barrel spigot.
しかしてチューブの一部には蛇腹部３を形成してある
が、この蛇腹部は前述のごとく薄肉に形成してあるの
で、すぐれて可撓性に富むものとなっている。Then, although the bellows portion 3 is formed in a part of the tube, the bellows portion is formed thin as described above, and thus has excellent flexibility.
したがって、エアゾール容器内の残液が少なくなったと
きに容器を傾けたり逆さにすると、ディップチューブは
蛇腹３部分で容易に撓んで吸込口たる下部開口端が容器
内の残液中に垂れ下がり、容器内の液を最後まで噴霧さ
せることができる。Therefore, if the container is tilted or turned upside down when the residual liquid in the aerosol container is low, the dip tube easily bends at the bellows 3 part and the lower open end, which is the suction port, hangs down into the residual liquid in the container. The liquid inside can be sprayed to the end.
＜効果＞ 上述した本発明方法によれば、エアゾール容器における
噴霧ノズル用弁体の液体取入口たるスピゴットへ外れな
いよう固嵌でき、それでいて蛇腹部の可撓性がすぐれて
いて、この蛇腹部の撓みにより容器内残液に吸込口たる
開口端を臨ませることができ、これによりエアゾール容
器用の液を残ることなく噴霧できるディップチューブを
容易に製造することができる利点がある。<Effect> According to the above-described method of the present invention, the spray nozzle valve body in the aerosol container can be firmly fitted to the spigot serving as the liquid intake port, and yet the bellows portion has excellent flexibility, and the bellows portion Due to the bending, the residual liquid in the container can be exposed to the opening end serving as the suction port, which has an advantage that a dip tube capable of spraying the liquid for the aerosol container without remaining can be easily manufactured.
