As shown in Fig. 9 and 11, a space B is inevitably generated between the sides of the inlay 10 and the vinyl paper 20, and through the space B thus generated, When the contents are dropped into the inpurpose 10 by the hopper not shown in the figure, the contents may not be immediately released into the inlay 10 but may be introduced into the space B, It is inevitably present that the contents are discharged to the space portion B due to the backward flow or recoil in the inlay 10. The contents discharged into the space portion B due to the flow of the container bag when the contents are discharged from the space portion B, that is, between the inward side 10 and the vinyl paper 20, There is a problem that friction with the vinyl sheet 10 and the vinyl sheet 20 can occur and the vinyl sheet 20 as well as the inlaid sheet 10 are damaged. There are still problems that remain uninvolved.

8 and 9, even if the contents are maximally introduced into the inside of the inlay 10, the contents can not be supplied as much as the space portion B, so even if the same container bag is used, the amount of the contents is relatively small, There is a side.
