PROBLEM TO BE SOLVED: To prevent foreign objects from the outside of a container from entering the container without obstructing the fitting between the container body and a lid body when a lid closed container is formed by a method wherein the height of a part which is closer to a hinge-form operating part, of a protruding part is formed larger than that of a part which is away from the hinge-form operating part, and the height of a recessed part is formed into a uniform height which is not more than the height of the part being away, of the protruding part. SOLUTION: On a protruding part 1 which is formed on the rim part of a container body A, the height h1 of a protruding part (1a) which is closer to a hinge-form operating part 3, is formed to be larger than the height h2 of a protruding part (1b) which is away from the hinge-form operating part 3, and in the meantime, the height of a recessed part 2 which is formed on the rim part of a lid body B, to be fitted on the protruding part 1, is formed in a manner to become a uniform height which is not more than h2 . When a lid closed container is formed, a flange part which is closer to the hinge-form operating part is not completely joined, and a gap is easy to generate at the time of storage and carrying, but since the container is formed so as to be h1 >h2 , and the protruding part 1 which is formed on the rim part of the container body A and the recessed part 2 which is formed on the rim part of the lid body B are joined, and the side surface of the protruding part 1 which is formed on the rim part of the container body A, closes the gap on the inside of the closed lid container when the lid is closed. |
