Abstract: In a paper container 10 having a hexahedral configuration which is formed by shaping paper into a box, the paper container 10 comprises a container main body 12 and a lid member 14 hingedly attached to a back side edge part of an upper end open surface 13 of the container main body 12 and adapted to open/close the upper end open surface 13, a front board 15 of the container main body 12 being formed with a concave cutout part 16 extending from the upper end open surface 13. The lid member 14 comprises an upper surface lid part 17 for covering the upper end open surface 13, a front surface lid part 18 large enough to cover the concave cutout part 16, and a pair of side lid parts 19 interposed between side edge parts of the upper surface lid part 17 and side edge parts of the front surface lid part 18 and adapted to vertically join the front surface lid part 18 with the upper surface lid part 17.
