The lower nozzle 31 is configured to be raised and lowered, and when a liquid content is injected, the nozzle 31 is inserted into the pouch at an appropriate depth and then rises when the injection is completed, and the nozzle 31 is opened in the opening 1A of the upper end of the pouch 1. The end of the stays.

Thus, when the nozzle 31 stays at the opening end 1A of the pouch 1, it is not necessary to open the pouch 1 one by one, and it is only necessary to sandwich the nozzle 31 between the opening ends 1A during the initial operation. Subsequent operations automatically move up and down for injecting the contents and moving the pouch while moving along the opening end 1A to which the nozzle 31 is connected.

④ Cutting Unit (40)

The cutting unit 40 is a device for individually cutting the pouch containing the contents passing through the injection unit 30, the cutting body 41 at the upper and lower ends of the cutting body 41 having a length up and down as shown in FIG. The upper and lower support parts 45A and 45B are provided to support and fix the upper and lower support parts 45A and 45B.
