PROBLEM TO BE SOLVED: To easily and correctly separate a container body 2 from a lid 3 during the use, to prevent the lid 3 from being carelessly separated, and to easily form a perforation 6 for separation. SOLUTION: The perforation 6 for separation is formed in a thick-walled portion in the vicinity of a thin-walled hinge 5 for folding provided on a connection portion 4 to connect the container body 2 to the lid 3. When opening/closing the lid 3, only the thin-walled hinge 5 is folded, and the perforation 6 is not affected thereby, and thus, the perforation is not carelessly separated. The perforation 6 with excellent cuttability can be easily formed in the flexible thick-walled portion. |
