Abstract
A paper container for containing liquid such as milk and juice is disclosed. The container is formed of a thick paper provided thereon with vertical and horizontal folding lines intersecting each other at right angles. The intersecting portions of the folding lines are such formed as to be different in configurations for a predetermined length. In this way, splits and pin holes can be prevented from occurring when the thick paper is folded along the grooves to build up a container.
