Then, the horn 5 moves toward the paper container 1 and the recessed portion at the tip of the horn 5 fits into the spout 2. Then, in this state, the peripheral edge of the horn 5 presses the peripheral edge of the mouth plug insertion hole of the paper container 1 from the outer surface and ultrasonic vibration is applied, whereby the mounting seat portion of the mouth cap is attached to the inner surface of the paper container 1. Is welded to.

Then, the support plate 3 is lowered by the action of the lower air cylinder, and the paper container 1 returns to the original position as shown in (e). With this, the spout welding step is completed, and the paper container 1 is sent to the next step.

ることがある。When the stopper of the liquid paper container is welded by utilizing ultrasonic vibration, the conventional method uses a jig for receiving the paper container transferred to the stopper welding portion as described above. Up and down movements such as raising using an air cylinder for insertion and lowering to the original position after completion of welding are required.
The mechanism of the device becomes complicated, and when raising the paper container, there may occur a trouble that the plug is displaced or comes off.
