A paper container,
The opening device includes a through hole provided in the top wall, and a synthetic resin lower plate having the same or a small through hole as the through hole,
At least a part of the outer periphery of the through hole of the lower plate has a fitting protrusion that fits in a pressed state, and the fitting protrusion is fitted on the upper face of the lower plate into the through hole of the lower plate. The upper plate is made of synthetic resin that is polymerized by superposition, and the barrier plate located on the inner surface of the top wall and covering the through hole provided in the top wall. The lower plate is the through hole provided in the lower plate. Is adhered to the outer surface of the top wall so as to be located in the through hole provided in the top wall, and the barrier film is fitted around the through hole on the inner surface of the top wall and the through hole of the lower plate. The upper plate is bonded to the top surface of the fitting projection of the upper plate.
