To provide a paper cup container configured to improve the step of a flange upper surface in the paper cup container having a flange part.
A paper cup container includes a paper layer, a cylindrical body part formed by a laminate having a thermoplastic layer provided at both sides, a bottom part, and a lid material. The body part has a body laminating part sealed by overlapping both side end edges of a body forming blank, and a flange part formed by evenly crushing an upper end outward after rolling up it more than once. The upper part of both right and left side end edge of the body forming blank has a corner cut part notched in a triangle shape. In the body laminating part, the thermoplastic layer extended from the paper layer is folded back outward in the side end edge being the inside of the container. In the upper corner cut part of the side end edge, the paper layer is not present in an intersection portion between the side end edge and the corner cut part, but a triangle resin part only comprising the thermoplastic layer is formed.
