CONSTITUTION: A lid body (2) is formed with an air passage hole for passing air from a container body (8) or external air. A check valve (4) controls the movement of internal air and external air through the air passage hole. An air control cap (6) has an air control hole (6-2) for controlling the speed and amount of internal air and external air. A packing (3) has a container inlet adhesion unit formed along the outside of the lid body. A double cap(5) has two packing grooves for mounting an O-ring which reinforces the airtight sealing of the check valve and the packing.
