PROBLEM TO BE SOLVED: To provide a closed container which may hermetically seal the interior of a container body by attaching a lid to the container body for storing objects, enables easy attachment/detachment of the lid, and maintains high sealability.SOLUTION: A closed container 1 includes: a container body 10; and a lid 20. The lid 20 comprises: a body part 30 formed by a hard synthetic resin; and an outer periphery part 40 formed by a soft synthetic resin and includes a fitting groove 50. The fitting groove 50 comprises: an inner side wall 31 formed by the hard synthetic resin; and a ceiling part 41 and an outer side wall 42 which are formed by the soft synthetic resin. A sealing rib 51 and an engagement protrusion 55 are formed by the soft synthetic resin in the fitting groove 50. When the lid 20 is attached to the container body 10, the engagement protrusion 55 engages with a flange part 15 of the container body 10 and the sealing rib 51 contacts with an upper end surface 16 of the flange part 15 to elastically deform and seal the interior of the container body 10. |
