<p><P>PROBLEM TO BE SOLVED: To enable the disassembly of a container to be more easily performed than a conventional one while maintaining the original strength and durability of the container in the gable top type liquid packaging paper container having a spout plug. <P>SOLUTION: An easily peelable varnish layer N for container disassembly is applied and formed on the internal surfaces of the overlapping top sealing plates 2C4 and 4C4, and the internal and external surfaces of the folding top sealing plates 1C4 and 3C4. In this case, the overlapping top sealing plates 2C4 and 4C4 are connected to the upper part of a rectangular top plate 2C31 having the spout plug and the upper part of a rectangular top plate 4C31, and are confronted with each other. The folding top sealing plates 1C4 and 3C4 are connected to the upper parts of folding equilateral triangular top plates 1C32 and 3C32. A top sealing section C4 which is heat-sealed with the confronted overlapping top sealing plates and the folding top sealing plates is pulled to the outside while peeling the top sealing section C4 through the easily peelable varnish layer on both sides of the butted confronted section C41, and the top section C3 is opened into an triangular shape. In addition, the bottom section C1 is opened into a square shape by cutting to open the three sides of the square bottom plate. After the container C is formed into a square cylindrical body, the container C is folded into a flat shape and disassembled. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
