And the valve seating groove 22 and the valve seating groove 22 in which the valve seating groove 22 and the air contact hole 24 are formed in the center portion to open and close the inlet, and are installed in the valve seating recess 22 of the lid body 20. Is mounted on the inner packing mounting groove 28-1 of the rim 28 of the lid body 20, and closes the inner surface of the inlet part 12 of the container body 10 when it is closed. A packing 40 for keeping the airtightness is provided.

The packing 40 extends in a substantially horizontal direction while being bent outwardly from the mounting portion 42 and the mounting portion 42 on the inner side, and is in close contact with the inner surface of the inlet portion 12 of the container body 10 and upwards near the end portion. It consists of the close contact part 44 in which the elastic protrusion 44-1 was formed, and this close contact part 44 is provided in the structure which becomes thinner toward the edge part.

Looking at the use of such a conventional vacuum container lid, as shown in Figure 10 while covering the lid of the inlet portion 12 of the container body 10 while the contents such as food and the like inside the container body 10 When the user presses the lid body 20 downward, the contact portion 44 of the packing 40 contacts the inlet portion 12 of the container body 10 and the lid is bent with its outer end facing upward. As it descends, air in the container body 10 is discharged from the container 1 while lifting the check valve 30 through the air communication hole 24. When the pressing force of the user is removed, the lowered lid is slightly raised by the elastic restoring force of the packing 40, thereby expanding the air in the container to vacuum the inside of the container.
