To provide an inexpensive paper container for a semisolid made easy to take out a content by horizontally tearing the barrel part of a gabled top type liquid carton to open it and made re-sealable.

This paper container for a semisolid is equipped with a tearing piece held by two weak lines in between provided to a square pole-like barrel part. The barrel part is torn off from the end part of the tearing piece to be opened. At a portion where the tearing piece crosses the heat-seal part of the barrel part in the vertical direction, an anti-sealing material is applied to either one of the opposing heat seal surfaces.
