Claims

[Scope of Claim for Utility Model Registration] (1) A trunk wall is constructed by winding a fan-shaped blank board made of a packaging material mainly consisting of paper layers and pasting both ends of the blank board. A sealed paper container characterized in that a linear bottom closure part is formed at the lower part of the wall, and a flat rectangular top closure part is formed at the upper part. (2) A synthetic resin film layer having tearability in one direction is provided inside the paper layer of the packaging material so that the tearing direction is from one end of the blank board to the other end, and 2. The sealed paper container according to claim 1, further comprising a grip portion formed by protruding a portion of the packaging material including the synthetic resin film layer from one side end of the blank plate which becomes the outer side when the blank plate is turned.
