【発明の詳細な説明】
本発明は、合成樹脂製チユーブ容器における下
端部のシール加工方法に関するものであつて、下
端部であるシールエンド部分を肉厚にしてシール

ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for sealing the lower end of a tube container made of synthetic resin. The purpose is to allow the shape of the part to be as desired.
従来よりの合成樹脂製のチユーブ容器は、円筒
形状の胴部下端部を扁平に押し潰し、この下端部
を加熱溶融化させてシール金型によりシールを達
成する手段をとつていた。 Conventional tube containers made of synthetic resin have a method of flattening the lower end of a cylindrical body, heating and melting the lower end, and achieving a seal using a sealing mold.
しかしながらこの手段によつて得られたシール
エンド部分の肉厚は、溶融により、胴部の周壁を
重ね合せた肉厚よりも薄くなつてしまうので、シ
ール部と胴部との接続部の強度が劣ることが多々
であつた。 However, the thickness of the seal end obtained by this method becomes thinner than the thickness of the overlapping peripheral walls of the body due to melting, so the strength of the connection between the seal and the body decreases. It was often inferior.
また、例えばシールエンド部分に孔を穿ち、容
器を逆さ吊りにし得る構成とする場合等の異形シ
ールが考えられるのであるが、該部分が肉薄であ
ると強度上問題が残り、しかも所望の形状を得る
ことができず、さらに別本物をシールエンド部分
に付形するには、別途の装置、工程を加えざるを
得ない。 In addition, an irregularly shaped seal can be considered, for example, where a hole is drilled in the seal end part so that the container can be hung upside down, but if this part is thin, there will be problems in terms of strength, and furthermore, it will not be possible to form the desired shape. In order to shape a separate piece into the seal end portion, separate equipment and processes must be added.
本発明は、上述した従来の欠点を解消するべく
創案されたものであつて、シールエンド部となる
容器の下端部を加熱溶融化させた後に折りたたん
で重ね合せ、さらにこの下端部を、シール金型を
兼ねた割り金型により、肉厚となつた所望の形状
のシールエンド部に成形するようにしたものであ
る。 The present invention was devised in order to solve the above-mentioned conventional drawbacks.The lower end of the container, which serves as the seal end, is heated and melted, and then folded and stacked, and the lower end is then folded into a sealing metal. A split mold that also serves as a mold is used to mold the seal end into a thick, desired shape.
以下本発明の一実施例を図面に従つて説明す
る。 An embodiment of the present invention will be described below with reference to the drawings.
図面にあつて、合成樹脂によつて成形された円
筒形状のチユーブ容器の胴部１は、逆立姿勢でそ
の下部が仮クランプ装置３によつて左右から扁平
に押し潰されて挾持され、下端部２は前記仮クラ
ンプ装置３から所望長さだけ突出している（第１
図）。 In the drawing, the body 1 of a cylindrical tube container made of synthetic resin is held in an inverted position with its lower part flattened from left and right by a temporary clamp device 3, and the lower end The portion 2 protrudes from the temporary clamp device 3 by a desired length (first
figure).
そして仮クランプ装置３より突出した前記下端
部２に対し、上方よりヒーター装置４を下降させ
てヒーター４′により加熱溶融化させる（第２
図）。 Then, the heater device 4 is lowered from above to the lower end portion 2 protruding from the temporary clamp device 3, and the heater 4' heats and melts the lower end portion 2 (second
figure).
次いでこの溶融状態の下端部２に対し上方より
曲げ治具５を下降させ、所望長さの下端部２を巻
回する等して折りたたんで重ね合せる（第３図）。 Next, the bending jig 5 is lowered from above to this molten lower end portion 2, and the lower end portion 2 of a desired length is rolled or otherwise folded and overlapped (FIG. 3).
このようにして折りたたまれ、かつ未だ溶融状
態にある下端部２をシール金型を兼ねた割り金型

る（第４図，第５図）。 The lower end 2 folded in this way and still in a molten state is sealed by the split mold 6 which also serves as a sealing mold, and the lower end 2 is shaped into a desired shape to form a seal end 2'. Yes (Figures 4 and 5).
この場合、第３図にあつての曲げ治具５の折り
曲げ回数、折り曲げ、重ね合せ状態は、仮クラン

所望のものに設定されることになる。 In this case, the number of times the bending jig 5 is bent, the folding state, and the overlapping state of the bending jig 5 shown in FIG. It is set to a desired value depending on the shape and shape.
また第４図にあつての割り金型６は、前記した
ようにシール金型をも兼ねているが、その成形型
面６′は、所望するシールエンド２′の形状に対応

態となるものである。 Furthermore, the split mold 6 shown in FIG. 4 also serves as a seal mold as described above, and its mold surface 6' corresponds to the desired shape of the seal end 2'. Therefore, when a hole for hanging is to be formed, for example, a pin is placed on the mold surface 6' and is passed through the lower end 2.
そして第１図にあつての下端部２の仮クランプ

なる。 The amount of protrusion of the lower end portion 2 from the temporary clamp device 3 in FIG. 1 is determined depending on the shape and wall thickness of the seal end 2' to be molded.

折曲げ加工を必要とする。 Furthermore, when the sheet body forming the body part 1 is made of a single layer synthetic resin, the number of times the lower end part 2 is bent, that is, the number of times it is overlapped, is not particularly limited, and the number of times the lower end part 2 is folded is not particularly limited. This can be determined according to the shape, but if the sheet is a laminated sheet using aluminum foil, the bending process must be performed at least twice, which is the number of times that the two end faces of the lower end can be wrapped around. do.

となつている。 As is clear from the above description, the seal processing method according to the present invention includes a step of folding and overlapping the melted lower end portion 2 between the melting step of the lower end portion 2 and the sealing step using the split mold 6. Therefore, the lower end portion 2 in FIG. 4 before being sealed by the split mold 6 has a wall thickness that is at least twice as thick as the wall thickness when the body portion 1 is flattened and stacked. It's summery.

化に富んだものにすることができる。 Therefore, the seal end 2' formed by the split mold 6 also has a sufficient wall thickness.
Furthermore, by forming the mold surface 6' of the split mold 6 into a desired shape, the shape of the seal end 2' can be varied.

損、脱落等のおそれもない。 Moreover, after the seal end is formed, there is no need for any equipment or process to shape the desired shape, for example, the hanging part, as a separate object, and the shape part is the seal end 2' itself that is integrated with the body, so it is strong. It has excellent properties and there is no risk of breakage or falling off.
