Abstract
A paper container includes four body portion panels forming a cylindrical body portion having a square section. The paper container is configured so that upper ends of the body portion panels are continuously provided with a pair of gable roof-forming panels which include exterior top seal panels opposed to each other, and provided with a pair of gable wall-forming panels which include interior top seal panels opposed to each other. Any one of the panels serves as a spout and is to be opened. The gable wall-forming panels are folded out between the gable roof-forming panels, and the exterior top seal panels and the interior top seal panels are heated and sealed with each other at a predetermined position so as to be hermetically sealed.
