PURPOSE: A sealing part structure is provided to seal the lower part of the storage space of a container by the sealing part, thereby ensuring a long-term storage inside the storage space of the container. CONSTITUTION: A sealing support part(101) is combined around the outer ring-shaped part(104) of a receiving part(201). A sealing part(103) is formed on the sealing support part and inside the sealing support part. The inner side of the outer ring-shaped part of the sealing part is tightly adhered to the inner wall(206) of the receiving part to maintain a sealing capability. A connection part(105) is formed between the sealing support part and the sealing part. A cutting line(102) is formed on both outer sides around the connection part. A protrusion part(110) is formed in an upper direction of the protruded sealing part. The opening part(107) of a main body having an outer ring-shaped projection is formed on a fixing part. A circular projection(207) of an operating unit is fixed around the opening part of the main body.
