When the lid 200 is closed or opened, the air inside the main body 100 communicates with the outside. When the lid 200 is closed, the airflow inside and outside the main body 100 can be blocked. At this time, the edge of the first sealing member 270 is kept in close contact with the inner surface of the main body 100 even when the lid 200 is inserted into or withdrawn from the main body 100, The flow of air except for the first exhaust port 213, the second exhaust port 271 and the third exhaust port 281 can be completely blocked.

First, an operation of tightening or unlocking the lid 200 to the main body 100 will be described.

The lid 200 is pushed into or pulled out of the main body 100 by pushing the lever 260 downward and allowing the air below the lid 200 to flow to the outside of the upper side as shown in FIG. At this time, the second sealing member 280 fixed to the lever 260 is pushed downward, and at least the second sealing member 280 near the lever 260 and the first sealing member 270 are separated from each other, The second exhaust port 271 and the third exhaust port 281 are opened and the sealing member 250 and the sealing protrusion 264 are separated from each other so that the first exhaust port 213 can be opened. Air in the lower part of the lid 200, that is, the inside of the main body 100, flows through the third exhaust port 281, passes through the second exhaust port 271, and then passes through the first exhaust port 213, As shown in FIG. As a result, the sealed state inside the main body 100 is released.

In this state, when the lid 200 is fastened to the main body 100, the cap 200 is fitted to the upper portion of the main body 100 to make the upper surface of the main body 100 closely contact the packing 240, And the body 230 and the body locking piece 110 may be fastened together. When the lid 200 is separated from the main body 100, the lid 200 and the main body locking piece 110 may be unlocked and then the main body 100 may be pulled in the opposite direction.

Next, the operation of sealing the inside and the outside of the main body 100 after the lid 200 is fastened to the main body 100 will be described.

4, when the lid 200 is closed, the lower air of the lid 200 is blocked from the upper side while the lever 260 is pulled upward. At this time, the second sealing member 280 fixed to the lever 260 is pulled upward, and at least the second sealing member 280 near the lever 260 and the first sealing member 270 come in close contact with each other, The exhaust port 281 is blocked by the shielding protrusion 272 and the sealing member 250 and the sealing protrusion 264 are brought into close contact with each other so that the first exhaust port 213 can be clogged. In addition, the second sealing member 280 can be clogged with the first sealing member 270 and clogged with the second exhaust hole 271. Therefore, the lower side of the lid 200, that is, the inside of the main body 100, is cut off from the outside on the upper side of the lid 200. As a result, the inside of the main body 100 becomes a sealed state.
