Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は２室を有するチューブ容器の製造方法に関す
る。The present invention relates to a method for manufacturing a tube container having two chambers.
従来より、２室を有するチューブ容器の製造方法とし
ては種々提案されているが、例えば実開昭58-61742号公
報に記載されているものが知られている。Conventionally, various methods of manufacturing a tube container having two chambers have been proposed. For example, the method described in Japanese Utility Model Laid-Open No. 58-61742 is known.
これは第５図ないし第８図に夫々横断面図で示すよう
に、収容部20と収容部21とを一体成型して両者の間に隔
壁22を形成したもの（第５図）、収容部20と収容部21と
を独立的に形成し両者を並設したもの（第６図）、第６
図に示すものにおいて収容部の接触面に嵌合凹凸23・24
を夫々形成したもの（第７図）、第６図に示すものにお
いて収容部の接触面に着脱自在の介在部材25を設けたも
の（第８図）である。As shown in the transverse sectional views of FIGS. 5 to 8, the accommodating portion 20 and the accommodating portion 21 are integrally molded to form a partition wall 22 therebetween (FIG. 5), accommodating portion. 20 and the accommodating part 21 are formed independently and are arranged side by side (Fig. 6), 6
As shown in the figure, the fitting surface 23.24
7 (FIG. 7) and FIG. 6 (FIG. 8), in which a removable interposition member 25 is provided on the contact surface of the accommodating portion.
また、この容器の口筒部27・28は第９図に示すように
収容部20・21に独立的に形成されており、これら半円状
の口筒部27・28を合わせた状態で正規の口筒部となるよ
うになっている。Further, the mouth cylinders 27 and 28 of this container are independently formed in the accommodating portions 20 and 21 as shown in FIG. 9, and the semi-circular mouth cylinders 27 and 28 are normally formed. It is designed to be the mouth tube part.
ところが、前記した従来のものにおいては、一体成型
した容器内に隔壁を形成したり、収容部を独立的に形成
する必要があるため成型が困難であり量産性に欠けると
いう問題がある。However, the above-mentioned conventional ones have a problem that molding is difficult and mass productivity is poor because it is necessary to form a partition wall in the integrally molded container or to separately form the containing portion.
また、口筒部を収容部に独立的に形成するものである
ため、両者の合わせ部分で段差が生じ易くこれに取り付
けられるキャップとの液密性が充分でないという問題が
ある。Further, since the mouth tube portion is formed independently in the accommodating portion, there is a problem in that a step is likely to occur at the mating portion of both and the liquid tightness with the cap attached to this is not sufficient.
本発明は前記事項に鑑みてなされたもので、成型が容
易であり量産性に優れ、併せて口筒部とキャップとの密
閉性をも向上させることができるようにした２室チュー
ブ容器の製造方法を提供することを技術的課題とする。The present invention has been made in view of the above matters, and is a method of manufacturing a two-chamber tube container that is easy to mold and has excellent mass productivity, and that can also improve the sealing property between the mouth tube and the cap. It is a technical task to provide a method.
本発明は前記技術的課題を解決するために、以下のよ
うな製法とした。The present invention has the following manufacturing method in order to solve the above technical problems.
即ち、筒状体１の中央部に、円周上に沿って筒状体１
の円周を残存部３を残して切り込み２を入れる。That is, at the center of the tubular body 1, the tubular body 1 is provided along the circumference.
Make a cut 2 on the circumference of the circle leaving the remaining portion 3.
この残存部３をヒンジとして筒状体１の両端部４・５
が密着する方向に折り、この残存部３側の開口部６に口
筒部７を接着する。Both ends 4 and 5 of the tubular body 1 using the remaining portion 3 as a hinge
Are folded in the direction in which the contact portions are in close contact with each other, and the mouth tube portion 7 is bonded to the opening portion 6 on the remaining portion 3 side.
一方、筒状体１の両端部４・５を密封して、独立した
２つの収容部８・９を形成する。On the other hand, both end portions 4 and 5 of the tubular body 1 are sealed to form two independent storage portions 8 and 9.
筒状体１を加工するだけで独立した２つの収容部を形
成でき、量産性に優れている。Only by processing the tubular body 1, two independent housing portions can be formed, which is excellent in mass productivity.
また、口筒部７は別体で取り付けるものであるため半
円状の口筒部を合わせるものに比較して精度を高くする
ことができ、密閉性にも優れている。Further, since the mouth tube portion 7 is attached as a separate body, the accuracy can be made higher than that in which a semi-circular mouth tube portion is combined, and the sealing performance is excellent.
前記切り込み２を筒状体１の円周の略（2/（２＋
π））が残存するように形成した場合、残存部３の長さ
を開口部６の全周の1/πとすることができるため開口部
６は略円形となる。Approximately the circumference of the cylindrical body 1 (2 / (2+
π)) is formed so as to remain, the length of the remaining portion 3 can be set to 1 / π of the entire circumference of the opening 6, so that the opening 6 has a substantially circular shape.
本発明の実施例を第１図ないし第４図に基づいて説明
する。An embodiment of the present invention will be described with reference to FIGS.
まず、柔軟性合成樹脂製の筒状体１の中央部に、第１
図に示すように円周上に沿って切り込み２を入れる。そ
の際、筒状体１の円周の（2/（２＋π））を残存して切
り込み２を入れる。First, in the central part of the tubular body 1 made of flexible synthetic resin, the first
Make a notch 2 along the circumference as shown. At that time, the notch 2 is made by leaving (2 / (2 + π)) of the circumference of the cylindrical body 1.
そして第２図に示すように前記残存部３をヒンジとし
て、筒状体１の両端部４・５が密着する方向に筒状体１
を折ると残存部３側の開口部６が略円形となる。As shown in FIG. 2, the remaining portion 3 is used as a hinge, and the tubular body 1 is moved in a direction in which both end portions 4 and 5 of the tubular body 1 are in close contact with each other.
When is folded, the opening 6 on the remaining portion 3 side becomes substantially circular.
次に、第３図に示すように、この残存部３側の開口部
６の口筒部７を接着する。この口筒部７は円形のショル
ダー部7aから筒体7bを立設し、その口縁にノズル体7cを
嵌着したものである。このノズル体7cは内部で２つの流
路を直角方向に曲げたものであり、独立した筒状体１内
に夫々連通せしめてある。Next, as shown in FIG. 3, the mouth tube portion 7 of the opening 6 on the remaining portion 3 side is bonded. In this mouth cylinder portion 7, a cylindrical body 7b is erected from a circular shoulder portion 7a, and a nozzle body 7c is fitted to the edge of the cylinder body 7b. The nozzle body 7c is formed by bending two flow paths in a direction perpendicular to the inside, and is made to communicate with each other in the independent cylindrical body 1.
そして、第４図に示すように筒状体１の両端部４・５
を加熱圧潰して密封し、独立した２つの収容部８・９を
形成する。続いて筒体7bにキャップ7dを螺合した後、内
容物を夫々の収容部８・９々充填し製品とする。Then, as shown in FIG. 4, both end portions 4 and 5 of the tubular body 1 are
Are crushed by heating and sealed to form two independent housing portions 8 and 9. Then, after the cap 7d is screwed into the cylindrical body 7b, the contents are filled in the respective storage portions 8 and 9 to obtain a product.
前記実施例では筒状体１に切り込み２を入れる際、筒
状体１の円周の（2/（２＋π））を残存して切り込み２

もよい。この場合、開口部６を楕円等の円形以外の形状
とすることができる。In the above embodiment, when the cut 2 is made in the tubular body 1, the cut 2 is made by leaving (2 / (2 + π)) of the circumference of the tubular body 1.
However, the present invention is not limited to this example, and the notch 2 having an arbitrary length may be formed from about 1/2 of the circumference to the limit where the containing portions 8 and 9 are not separated. Good. In this case, the opening 6 can have a shape other than a circle such as an ellipse.
