Abstract: A vacuum receptacle lid for easy sealing includes a lid body that closes and opens an inlet portion of a receptacle body provided with a space containing contents, a valve installation hole formed at a part thereof, at least one air vent hole, and a packing installation groove which is opened downwardly in a C shape inside a rim thereof. A check valve providing a combining projection at a bottom surface of a body portion enclosing the air vent hole is inserted into and combined with the valve installation hole and exhausts air of the inside of the receptacle body via the air vent hole blocking inflow of external air by enclosing, opening and closing the air vent hole. A packing is accommodated and installed at the packing installation groove and includes upper, lower, and intermediate contact portions which have a cross-section of a zigzag shape.
