In order to smoothly perform an opening and closing operation of an opening and closing lid part while ensuring the airtightness of the interior of a packaging body, a lid body for a wet wipe packaging body is provided with a frame body (110) in which a lid opening part (111) that surrounds an opening part (11) from outside is formed, and an opening and closing lid part (120) which is rotatably connected to the frame body (110) via a hinge part (130) and closes the lid opening part (111) from the front surface side. A fitting part (112) protruding to the front surface side is circularly provided in the frame body (110). The fitting part (112) is formed by an inner wall part (113), an outer wall part (114), and a groove part (115) formed between the inner wall part (113) and the outer wall part (114), and a protruding part (121) that protrudes to the back surface side and fits in the groove part (115) is circularly provided in the opening and closing lid part (120). The distance between the protruding part (121) and the hinge part (130) at a position where the lid opening part (111) and the hinge part (130) are closest to each other is greater than or equal to five times the height of overlap of the protruding part (121) and the fitting part (112). |
