CONTAINER MADE OF COMPOSITE PAPER |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a paper-made container having a polygonal opening and capable of preventing the leakage or the like of a content from a corner of a polygonal shape when heat-sealing the opening with a lid. <P>SOLUTION: The paper-made container is formed of a paper-made base material with a plastic-made film layer laminated at least on one side of raw paper, and has a polygonal opening, and an edge continuous to the opening. A strip-like flexible plastic member having a predetermined width is welded along the opening so as to cover the opening. A structure free from leakage at the opening can be obtained by heat-sealing the lid by using a section of the plastic member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
