The lid for a conventional sealed container having such a configuration has an arc-shaped outer lid in which a plurality of insertion holes are formed in a central portion thereof, and a fitting groove portion having a pivoting protrusion is formed in the lower portion thereof, and a pressure plate is formed in the inner central portion of the lid. Consists of a circular inner lid that is inserted into the outer periphery of the outer lid with a fixed thickness formed, the life of the lid is extended, the one-touch operation on the pressing piece by simply releasing the sealing force between the lid and the container of the lid It is easy to open and close and can be reused, thereby reducing the burden of purchasing cost.

However, as shown and described, the components are complicated, so that not only the increase or decrease in production cost, but also the method of manipulating the pressing pieces is a method of catching and tightening them on both sides. This adds a lot of cost to households with the hassle of having to repurchase new ones.

The present invention is devised to solve the problems with the lid for the conventional hermetic container as described above, there is no difficulty in opening the lid by discharging the air in the hermetic seal by a simple operation, and the configuration is simple. The purpose is to provide a lid for a sealed container that can reduce the production cost.
