悪いという問題があった。To make such a spiral paper can,
When the tubular body is cut to an appropriate length, the tubular body is cut from the outside. When the tubular body is cut from the outside,
The end portion cut by being pressed inward from the outside is deformed inward, and in this state, it is impossible to attach the bottom lid or the base as described above to the end portion of the main body. That is, the bottom lid and the base attached to the end of the main body are attached by winding the end of the main body like the can lid.
Therefore, if the cut end remains deformed inward, the bottom lid and base cannot be attached, and it is necessary to cut the tubular body from the outside and then push the end deformed inward outward. It was It is possible to attach a bottom lid or a base to the end by expanding the end deformed inward in this way to the outside. The end faces are separated and become uneven, and when this end part is wound with the bottom lid or the mouthpiece, the cut end face of the end part is not uniform, so the sealing property between the bottom lid or the mouthpiece and the cut end face at the winding part is There was a problem of being bad.
