<p><P>PROBLEM TO BE SOLVED: To provide a paper-made container for a liquid, used for storing the liquid such as beverage, seasoning agent, detergent, medical supplies and industrial chemicals, easily handled, and having an improved self-standing property so that the container is not easily topped by absorbing unevenness of a container bottom part without impairing the characteristics and the appearance of the paper-made container for the liquid. <P>SOLUTION: A square paper-made container for a liquid is formed by forming an original paper in a cylindrical shape while one end thereof forms a folded bottom part. The level of a surface in which the original paper of the container bottom is lower than a ridge part so that the original paper part folded and superposed when forming the bottom part, is not projected from a plane formed by four points supporting the container bottom part. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
