Disclosed is a vacuum container including a container body, a lid for closing the upper end of the container body, a depression defined on the lid, a boss formed on the lid and defined with an air hole, a rotary cover rotatably arranged in the depression and having an accommodating space, and a closure member having a through-hole and coupled to the rotary cover. The vacuum container also includes an airtightening element having a hollow body part fitted around the boss and a lip part extending in a radial direction from the hollow body part. A vacuum maintaining member includes a semi-spherical body received in the closure member and having an airtightening flange part brought into contact with the lip part of the airtightening element. An exposure bar extends upward from the semi-spherical body such that a part of the exposure bar is exposed to the outside through the through-hole of the closure member. The exposure bar is moved upward and downward in accordance with a vacuum state of the inside of the container body. The vacuum container effectively and reliably maintains the inside of the vacuum container under a vacuum state. Also, a user is allowed to easily confirm the vacuum state of the container with the naked eye, and to check an initial vacuumization date of a food item or the remaining effective vacuumization periods, as occasion demands.
