<P>PROBLEM TO BE SOLVED: To provide a container with an inner lid which enables an inner lid to be securely installed with the top end opening of a mouth part covered with the inner lid in a loosely fitted state without allowing the inner lid to be stuck on the inner surface of the top surface part of a cap. <P>SOLUTION: The container 10 with the inner lid is provided with the inner lid 22 with a flange which is installed on the top end opening 14 of the mouth part 13 in a loosely fitted state with the flange 20 placed on the mouth part 13 of a container body 11 and allows the cap 12 to be mounted on the mouth part 13. When the cap 12 is mounted on the mouth part 13, a part 26a of the inner lid body 21 gets into contact with the inner part 18b of the inner surface 18 of the top surface part of the cap 12 before the circumferential edge part 18a of the inner surface 18 of the top surface part of the cap 12 gets into contact with the flange 20 placed on the mouth part 13. In a state where the inner surface 18 of the top surface part is in contact with the flange 20, the part 26a of the inner lid main body is pressed by the inner part 18b of the inner surface 18 of the top surface part and the inner lid body 21 is elastically deformed to produce an urging force X in the direction of pushing up the cap 12. <P>COPYRIGHT: (C)2009,JPO&INPIT |
