Abstract
A bag container including a synthetic-resin container body shaped by using a mold and including a spout-forming portion and a filling inlet portion that project outward therefrom. Contents are first filled through the filling inlet portion, and then fusion-bond sealing is applied to the filling inlet portion. The filling inlet portion has, at its sealing base portion, a square cross-sectional shape. A tip-end-side cross-section-changing portion and a cylindrical portion are provided on the tip-end side with respect to the sealing base portion. Four triangular panels each isosceles triangle shaped are connectedly provided on the side of the container body with respect to the sealing base portion along a circumferential direction of the filling inlet portion, a base of each isosceles triangle formed of one of sides of the square cross-sectional shape. When the fusion-bond sealing is to be applied to the filling inlet portion, a region on the tip-end side with respect to the sealing base portion is folded flat while positioning a pair of opposing corners on opposite edges of the filling inlet portion.
