Abstract (en)
[origin: EP0376612A2] A tightly sealed paper container, wherein a through hole (2) is formed in a container material laminated with a thermoplastic synthetic resin layer provided at the outermost layers of the front and rear of a paper board base, a lining member (3) made of synthetic resin and having a smaller hole (4) than the through hole is so positioned that the small through hole of the lining member is included within the through hole of the container material so as to be contacted with the inner surface of the container, and a pull tab piece (5) covering the through hole of the container material is contacted with the outer surface of the container. The surrounding of the small through hole of the lining member slightly projects outwardly from the front surface of the container material. A half-cut line (6) is provided on the outer surface of the container along a boundary between a contact portion of the pull tab piece to the outer surface of the container and a non-contact portion of the pull tab piece for a knob.
