□ This ring 2 has a flange part 14 at the upper end and a container body 10.
A flexible thin film material is attached to the upper surface of the flange portion 14 to form a main deposit. Further, the diameter of the welded portion 15 is reduced toward the tip, and two protrusions 16 are formed along this outer peripheral portion. This protrusion 1'6

A spirally wound paper tube is made of a straight paper tube with a plastic interior film 12 pasted on the inside of a plurality of paper layers 11. A long plastic tape wrapped around 1
3, and the joint portion of this plastic tape 13 is formed by overlapping a flat edge 13a on one side and a bag-shaped edge 13b bent into a bag shape on the opposite side.

部分において僅かに容器本体１０の内方に突出する。Then, the seam portion of the innermost paper layer 11 is placed on top of this seam portion. Therefore, plastic tape 1
The three-layer interior film formed by No. 3 slightly protrudes inward of the container body 10 at the seam portion of the paper layer 11.
容器本体１の上端部はテーパ状に外側に拡径されたリン
グ装着部１ａが形成されている。この装着部１ａの傾斜
角度はリング溶着部１５の傾斜角よりも僅かに大きく形
成されている。The upper end of the container body 1 is formed with a ring attachment part 1a whose diameter is expanded outward in a tapered shape. The angle of inclination of this mounting portion 1a is formed to be slightly larger than the angle of inclination of the ring welded portion 15.
容器本体上部の装着部１ａのテーパ状の傾斜角度は本出
願人の実験によれば３乃至６度の範囲が最もリング２の
溶着に適している。According to experiments conducted by the applicant, a range of 3 to 6 degrees is most suitable for welding the ring 2 to the tapered angle of the mounting portion 1a on the upper part of the container body.
すなわち、リング２を容器本体１０に超音波溶着する場

る。That is, when the ring 2 is ultrasonically welded to the container body 10, the ring 2 is attached to a horn of an ultrasonic welding device and is vibrated together with the horn at about 18,000 hz. At this point, if the taper angle of the welded portion 1a of the container body is smaller than 3 to 6 degrees, the amount of heat generated due to friction will be small and complete welding will not be achieved. Moreover, if it is larger than this range, the downward load of the horn acts on the ring 2, causing the flange portion 14 to become uneven, and further cracking may occur.

巻き締めて固着する。When manufacturing the paper tube container 10, one or more paper layers 1
A metal can 3 containing quicklime 4 and a water container 5 is inserted from below into a container body 1 formed of an interior film layer 12,
The metal can 3 and the metal bottom lid 7 are tightly wound and fixed to the lower end of the container body.
この後、超音波溶着装置により容器本体１０の上部にリ
ング２を溶着する。Thereafter, the ring 2 is welded to the upper part of the container body 10 using an ultrasonic welding device.
この場合、容器本体１０の上端部を予めテーパ状に拡径

ホーンをリング２に押圧し、リング２を振動させる。In this case, the diameter of the upper end of the container main body 10 is expanded in advance into a tapered shape to form the ring attachment part 1a, and the paper tube container 10 formed in this way is shaped so that the upper end thereof is tapered in correspondence with the container main body. The container body 10 is housed in an anvil formed in the container body 10 and held so that the container body 10 is not deformed. After the ring 2 is attached to the attachment part 1a of the container body 10, the horn of the ultrasonic wJ@ device is pressed against the ring 2 to vibrate the ring 2.
容器本体１０の装着部１ａはテーパ状に形成されている

との間には隙間が生じることなく完全に溶着することが
できる。Since the attachment part 1a of the container body 10 is formed in a tapered shape, the welded part 15 of the ring 2, that is, the two protrusions 16 of this welded part, completely contact the inner surface of the attachment part 1a of the container body, and the welded part 15 of the ring 2 completely contacts the inner surface of the attachment part 1a of the container body. sealed. Furthermore, since the seam part of the interior film 12 is formed in three layers, even if a gap is formed at the seam part of the paper layer that overlaps the seam part of the interior film, only a part of the film will slip into this gap. This prevents the film inside the container body from slipping into the gaps between the paper layers. Therefore, the ring 2 and the interior film 12
They can be completely welded without any gaps between them.

Since the ring that attaches the top lid of the material is ultrasonically welded to the tapered attachment part of the container body, it can be welded in a liquid-tight manner, completely preventing leakage of the contents. Therefore, the upper end of the paper tube container can be sealed extremely easily, and the manufacturing cost of the paper tube container can be reduced.
