It is also possible to lower the member 2 so that the mouth of the folded bag b is folded deeper to the outside of the packaging container a.

Further, in the present invention, since the size and position of the insert 1 and the locking member 2 can be adjusted, even if the size and depth of the bag and the packaging container are changed,
The inner bag can be satisfactorily hung. Regarding the size of the mouth of the bag, as described above, the frame portions of the bottom portion 12, the top portion 13 and the intermediate portion 14 are extended leftward or rightward and the columns 11 are moved leftward or rightward. As a result, the position of each locking member 2 provided in the intermediate portion 14 also changes, and a bag with a wider mouth can be accommodated. Since the expansion position of each locking member 2 can be adjusted and changed by adjusting and changing the stroke of the air cylinder 18 for expansion, or adjusting and changing the length of its piston rod. It is also possible to carry out only such adjusting means. However, for major changes, it is advantageous to change the positions of the support columns 11 and the like, and by changing the positions of the support columns 11 and the like, the size of the entire insert 1 can be adjusted, so that a more reliable insertion is possible. Work becomes possible.

Regarding the depth of the bag, as described above, by rotating the screw shaft 24 and moving the sliding air cylinder 21 up and down, the intermediate portion 14 attached to the piston rod and the locking member 2 are vertically moved. The position can also be adjusted. Therefore, the length between the locking member 2 and the bottom portion 12 of the insert 1 can be adjusted, and it is possible to cope with bags having different depths. It should be noted that a length between the locking member 2 and the lower end of the insert 1 can be reduced by providing a replenishing member (not shown) at the bottom 12 of the insert 1 instead of or in combination with such adjusting means. It may be adjusted.
