A vacuum cover inscribed with a container is provided to prevent deformation or the decrease of sealability although the vacuum cover is put into a microwave oven or hot food is put in the container. A vacuum cover(Ccd) inscribed with a container is composed of an elastic body(Bcd) for cutting off a storing space from the outside and exhausting or sucking the air from/into the storing space according to the displacement form and a valve(Vu) installed at the body to discharge the internal gas of the storing space, to make the gas flow into the storing space, or to discharge and insert the gas. The body comprises a flange coming into contact with the upper end of the container forming a storing space isolated from the outside together with the body and a closing projection coming into contact with the inside of the container. An air layer is formed at the contact surface of a corresponding unit by the flange and the closing projection.
