PROBLEM TO BE SOLVED: To provide a paper container wherein a material cost of a pour-out device or the like is not necessary, a machining cost is not increased, inconsistent functions including sealability and unsealability can be easily satisfied, and a pour-out port which is good in appearance at the time of unsealing can be easily formed. SOLUTION: The paper container 1 comprises a laminate including a base layer made of a paper layer, an internal layer having at least a heat-bonding resin layer on one of surfaces of the base layer and an external layer having at least a heat-bonding layer on the other surface. A cutting blade 20 is formed on the paper container 1 on the external layer and the base layer with the internal layer of the paper container 1 left to provide a pour-out port at the time of pouring contents out of the paper container 1. |
