1. A method for manufacturing a sheet material container
wherein the sheet material container comprises:
one or a plurality of sheet members including a main-body forming sheet member that has an outer film layer and an inner film layer which are mutually stacked,
a containing region that accommodates contents, and
a container body that is configured from the main-body forming sheet member and that surrounds the containing region, and
the main-body forming sheet member having a main-body sealing portion, which is an attached region between the outer film layer and the inner film layer, and a non-attached region where the outer film layer and the inner film layer are partially not attached, and further having a filling portion where a filler is enclosed between the layers of the outer film layer and the inner film layer in the non-attached region,
the method comprising:
introducing gas into the containing region so as to expand the container body;
injecting the filler between the layers of the outer film layer and the inner film layer in the non-attached region in a state where the container body has been expanded,
wherein the sheet material container has an inner bag that defines the containing region,
wherein the inner bag is configured from an inner-bag forming sheet member, which is an innermost-layer sheet member among the one or plurality of sheet members,
wherein the main-body forming sheet member has an external air intake hole, through which external air is taken in, in a gap between an outer surface of the inner bag and an inner surface of the container body,
wherein closing the external air intake hole is performed after the expanding of the container body, and
wherein injecting the filler is performed in a state where the external air intake hole is closed.
