    摘要： A tightly sealed paper container, comprising a through hole is formed in a container material (3) laminated with thermoplastic synthetic resin layers (4),(5) provided on the front and rear surfaces thereof, a bottom board (8) of the resin and having a through hole (6) substantially equal to the through hole (6) is bonded to the front surface of the container such that the through hole of the bottom board (9) substantially coincides with the through hole (6) of the container material (3), a top board (11) of the resin and having a coupling projection (12), the outer periphery of which is at least partially coupled in pressure contact into the through hole of the bottom board (8), is superposed on the bottom board with the coupling projection coupled into the through hole of the bottom board, and a barrier film (14) covering the through hole of the container material is laminated on the rear surface of the container, the barrier film being bonded to the rear surface of the container and the top surface of the coupling projection.
