<p><P>PROBLEM TO BE SOLVED: To provide an easily-disassemblable paper container allowing easy manual disintegration of a bottom section without using a cutting tool. <P>SOLUTION: The paper container 1 is made of a laminated sheet 10 in which a sheet paper is prepared as a base material 11 and a surface layer 12 and back layer 13 are made of polyethylene and a vapor deposition film 16 formed by depositing a thin film 15 of a metal or inorganic oxide on a base material film 14 is laminated in the inside of the back layer via an adhesive layer 17. The paper container 1 is provided with: a square cylindrical trunk section 2 having four side plates 21, 21, 21, and 21, and a glue strip 22 connected with one of the side plates and also connected with the adjacent side plates; a top section 3 formed on one opening end of the trunk section; and a bottom 4 formed on the other opening end of the trunk section. A first cut f and second cut g are arranged on the sheet paper 11 section only of the laminated sheet, or are arranged to reach the sheet plate 11 section through the surface layer 12 of the laminated sheet, and a third cut h is also arranged on the back layer 13 only so as to approximately penetrate the back layer. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
