PROBLEM TO BE SOLVED: To facilitate the breaking of a wrapping film which is hermetically joined and covers a container main body wherein the opening section is closed with a lid by forming an external wide flange section along the outer contour of the lid, forming a deep groove section on the internal side of the flange section, and at the same time, forming a flat surface section which flushes with the flange section, on the internal wall surface of the deep groove section. SOLUTION: For a lid 15 which covers the opening section of a container main body 11, an external wide flange section is formed along the outer contour, and a deep groove section 17 of which the external wall surface is hermetically joined and fitted in the internal wall of the opening section, is formed on the inside of the flange section 16, and at the same time, an internal wide flat surface section 18 which flushes with the flange section 16 is formed in a manner to be connected to the internal wall surface of the deep groove section 17. Then, the external wide flange section 16 and the internal wide flat surface section 18 are formed in a manner to flush with each other, and thus, a wrapping film W is hermetically joined to both sections across the deep groove section 17, and covers both sections. Therefore, the wrapping film W can be firmly joined to the external wide flange section 17 and the internal wide flat surface section 18, and the wrapping film W can be easily broken by the tip of a finger nail or the like. |
